Patent Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a first aid adhesive plaster for
curing or disinfecting an affected part of a skin like a wound or
an insect bite by sticking it on the affected part, and particularly
relates to the first aid adhesive plaster which restrains delay
in curing of the wound or the like or pigmentary deposit on the
wounded part of the skin which are caused by exposure to ultraviolet
rays and suppress an influence of the ultraviolet rays on a liquid
medicament and an ointment.
[0003] 2. Description of the Prior Art
[0004] A conventional first aid adhesive plaster, which is widely
known, comprises an adhesive sheet having a rectangular shape, a
pad of a gauze or the like stuck to a center of an upper surface
of the adhesive sheet and release papers covering the upper surface
of the pad and separable right and left. When used, the release
papers are removed and the first aid adhesive plaster is stuck to
the skin in a state that the pad is placed on the affected part
like the wound. To cure or to disinfect the affected part like the
wound more effectively, the first aid adhesive plaster has been
invented in which a capsule body encapsulating a liquid medicament
is placed on the pad adhering onto the adhesive sheet, as described
in Patent Document 1, for example. When it is used, a thin film
made of an aluminum foil forming a bottom face of the capsule body
is broken by a projection with a sharp tip projecting downwardly
from the upper part of the inner surface of the capsule body by
pressing and deforming an upper part of the capsule body so that
the liquid medicament in the capsule body may flow on the pad to
make the pad impregnated with the medicament.
[0005] Further, as described in Patent Document 2, the first aid
adhesive plaster has been invented in which an ointment is laid
on the upper surface of the pad adhering onto the center of the
upper surface of the rectangular adhesive sheet. The pad having
a layer of the ointment is covered with a synthetic resin protecting
cover, which is removably stuck to an adhesive agent layer of the
adhesive sheet, and the release paper is stuck onto the adhesive
layer of the adhesive sheet except the part of the protecting cover.
[0006] However, when any of the above-mentioned first aid adhesive
plasters are used by sticking them to the affected part of the skin
like the wound or the insect bite, exposure of the affected part
to ultraviolet rays while repairing of the skin delays regeneration
of a normal skin due to penetration of the ultraviolet rays through
the pad, and causes a change in a color of the skin leaving the
pigmentary deposit or a trace of wound.
[0007] In view of the circumstances, the first aid adhesive plaster
has been developed (Patent Document 3, for example) in which the
adhesive sheet is formed by laying the adhesive agent layer on a
supporting sheet, being a uniaxial oriented film, and the pad is
stuck onto the adhesive sheet, which is covered with the release
paper. The uniaxial oriented film is made of a thermoplastic resin
composition prepared by compounding thermoplastic resin with inorganic
filler like calcium carbonate, calcium oxide, silica, titanium oxide,
or alumina, etc.; with an additive like a dispersing agent, a heat
stabilizer, an ultraviolet absorber, a lubricant, or a pigment.

No. 1893533.
[0009] [Patent Document 2] Japanese Patent Application Laid-Open
No. 2001-104367.
[0010] [Patent Document 3] Japanese Patent Application Laid-Open
No. 5-111507.
[0011] However, although the supporting sheet made of the thermoplastic
resin and forming the adhesive sheet includes an ultraviolet blocking
agent, the manufacturing cost is high since the whole supporting
sheet is formed with the thermoplastic resin composition including
the inorganic filler, the dispersing agent, ultraviolet blocking
agent, the pigment or the like. Moreover, air permeability of the
whole adhesive sheet is not enough and a rash is developed on the
skin where the adhesive layer adheres. In addition, it is uneconomical
to include the ultraviolet blocking agent in an unnecessary part
of the plaster, being the part except the pad which is placed on
the wound or the like. Furthermore, when the necessary number of
the first aid adhesive plaster are taken out of a storing bag or
a storing box to be carried, the first aid adhesive plasters are
exposed to the solar light (ultraviolet rays) and the efficiency
of the medicine is influenced.
SUMMARY AND ADVANTAGES OF THE INVENTION
[0012] This invention is made in view of the above-mentioned problems.
A purpose of the invention is to provide the first aid adhesive
plaster in which an ultraviolet blocking function is demonstrated
evenly and only at the area of the pad, so that it may be mass-produced
at a low price and that deterioration of the efficiency of the medicine
may be suppressed to the utmost even when the first aid adhesive
plaster is exposed to the sun light.
[0013] In the first aid adhesive plaster to be used in a manner
that the release papers stuck onto the adhesive agent layer of the
adhesive sheet is removed and the adhesive sheet is stuck onto the
skin in a state that the pad member stuck onto the center of he
upper surface of the adhesive agent layer is placed on the affected
part of the skin like the wound or the insect bite, this invention
according to claim 1 is characterized by the pad member comprising
the pad to be placed on the affected part of the skin and a ultraviolet
blocking film disposed on the pad.
[0014] In the meantime, the ultraviolet blocking film is the film
containing fine particles like titanium oxide, zinc oxide, magnesium
silicate, or magnesium oxide dispersing and reflecting ultraviolet
rays, the film coated with a synthetic resin coating material compounded
with such fine particles, the film containing a salicylic acid-based
ultraviolet absorbing agent like salicylic acid 2-ethylhexyl, or
the film coated with the synthetic resin coating material compounded
with such ultraviolet absorbing agent.
[0015] In the first aid adhesive plaster structured as above, the
invention according to claim 2 relates to a preferable structure
of the pad member. Namely, the preferable structure is that the
ultraviolet blocking film is laid on the lower surface of the pad,
or the ultraviolet blocking film is interposed between the two pads
that are laminated.
[0016] Further, the invention according to claim 3 relates to another
preferable structure of the pad member. Namely, the pad member comprises
the pad, a cushioning material laid on the lower surface of the
pad, and the ultraviolet blocking film disposed between the pad
and the cushioning material or the ultraviolet blocking film disposed
on the lower surface of the cushioning material.
[0017] Furthermore, the invention according to claim 12 relates
to the first aid adhesive plaster for demonstrating an ultraviolet
blocking function without using the ultraviolet blocking film. Namely,
in the adhesive plaster to be used by removing the release papers
stuck onto the adhesive agent layer of the adhesive sheet, and then
by sticking the adhesive sheet onto the skin while placing the pad
member, adhering to the center of the upper surface of the adhesive
agent layer, on the affected part of the skin like the wound, at
least the upper layer part or the lower layer part of the pad is
formed to be an ultraviolet blocking agent layer containing an ultraviolet
blocking agent.
[0018] In the first aid adhesive plaster, the invention is characterized
by a net wrapping the pad member, the lower surface of which net
is stuck onto the adhesive agent layer of the adhesive sheet.
[0019] The invention is characterized by the pad, constituting
the pad member, which is made of the rectangular gauze or the unwoven
fabric with a fixed thickness. In the invention, the ultraviolet
blocking film laid on the pad of the first aid adhesive plaster
described in the above claims is made of the synthetic resin film
containing the ultraviolet blocking agent composed of titanium oxide,
zinc oxide or a processed substance of these, or is made of the
synthetic resin film coated with a layer of the ultraviolet blocking
agent. The ultraviolet blocking film is formed to have a substantially
the same size and shape as the form of the pad in plan view. The
invention is characterized by the ultraviolet blocking film formed
to be a porous film having a number of small air holes all over.
[0020] In the first aid adhesive plaster described in the above
claims, the invention is characterized by the release papers stuck
onto the adhesive agent layer of the adhesive sheet for covering
the pad member. The invention is that the ointment is laid on the
pad member, which is covered with the synthetic resin protecting
cover, and the protecting cover is releasably stuck to the adhesive
agent layer of the adhesive sheet. Further, the invention is that
the capsule body made of synthetic resin, whose opening bottom face
is closed by an aluminum foil, for encapsulating the liquid medicament
is placed on the pad member. The capsule body is held on the pad
member by the release papers stuck onto the adhesive agent layer
of the adhesive sheet.
[0021] Further, in the first aid adhesive plaster described in
the above claim, the invention is characterized by the ultraviolet
blocking film which is laminated and integrated with at least the
part corresponding to the encapsulated liquid medicament at least
on one side face of the synthetic resin capsule body.
[0022] Furthermore, the first aid adhesive plaster described in
the above claims, the invention is characterized by the ultraviolet
blocking film laminated and integrated with at least a part corresponding
to the pad member on at lease one side face of the protecting cover
in the first aid adhesive plaster comprising the pad member, the
ointment and a dome-shaped protecting cover for protecting the ointment.
[0023] According to the invention described in claim 1, the pad
member adhering to the center of the upper surface of the adhesive
layer of the adhesive sheet comprises the pad placed on the affected
part of the skin like the wound and the ultraviolet blocking film
disposed on the pad. Therefore, the first aid adhesive plaster having
the ultraviolet blocking function is manufactured easily at a low
cost only by incorporating the ultraviolet blocking film with the
pad of the first aid adhesive plaster of a conventional structure
in a state of layers without compounding the ultraviolet blocking
agent with a base material sheet of the adhesive sheet. Further,
since characteristics of the adhesive sheet like air permeability
and moisture permeability are hardly ruined, the rash is hardly
developed on the skin. Furthermore, delay in curing of the affected
part due to the ultraviolet is eliminated and the change in the
color of the skin or the pigmentary deposit is restrained by covering
the affected part like the wound or the insect bite with the ultraviolet
blocking film to restrain exposure of the affected part to the ultraviolet
rays.
[0024] According to the invention described in claim 2, the pad
member has the structure that the ultraviolet blocking film is laid
on the lower surface of the pad or is interposed between two layers
of the pad, which are laminated. Therefore, the pad is provided
with the ultraviolet blocking function by the ultraviolet blocking
film without ruining a soft touch of the pad and without damaging
a lip of the wound. In addition, the pad member with the ultraviolet
blocking function in a simple structure is manufactured easily.
[0025] Further, the pad member according to the invention described
in claim 3 comprises the pad, the cushioning material laid on the
lower surface of the pad, and the ultraviolet blocking film disposed
between the pad and the cushioning material or disposed on the lower
surface of the cushioning material. Therefore, in addition to the
effect of the pad member mentioned in claim 2, the pad is softly
pressed against the whole affected part like the wound by the cushioning
material with a proper pressing force, and an effect of curing the
affected part is promoted without damaging the wound or the like.
[0026] The invention according to claim 12 relates to the first
aid adhesive plaster structured to demonstrate the ultraviolet blocking
function without using the ultraviolet blocking film. Namely, the
pad member has the structure that at least one of the upper layer
part or the lower layer part of the pad is formed to be the ultraviolet
blocking agent layer containing the ultraviolet blocking agent.
Therefore, the pad member is made to have the ultraviolet blocking
function while hardly ruining the air permeability and flexibility
of the pad. Consequently, exposure of the affected part to the ultraviolet
rays are restrained, delay in curing the affected part is eliminated,
and the change in the color of the skin or the pigmentary deposit
is restrained by the ultraviolet blocking layer while the pad is
in soft contact with the affected part like the wound or the insect
bite.
[0027] According to the invention, the pad member is wrapped with
the net and the lower surface of the net is stuck onto the adhesive
agent layer of the adhesive sheet. Therefore, the pad constituting
the pad member and the ultraviolet blocking film are kept in a form
of stably and integrally laminated layers by the net without deviation
and separation even when the ultraviolet blocking film is placed
on the lower surface of the pad without being stuck, and the pad
member is accurately placed on the affected part like the wound.
Further, when the first aid adhesive plaster is manufactured, the
pad member may be handled without deforming it since the whole pad
member is covered with the net, and it may be placed on an accurate
position of the center of the upper surface of the adhesive sheet,
resulting in improved manufacturing efficiency.
[0028] The pad constituting the pad member is made of the rectangular
gauze or the unwoven fabric having a fixed thickness, as described
in the above claim. Therefore, the pad that excels in flexibility,
air permeability and moisture permeability is provided as mentioned
above. In addition, the ultraviolet blocking agent layer as described
in claim 12, is easily formed by coating or impregnating at least
one of the upper layer part and the lower layer part of the pad
with a suspension liquid or a paste of the ultraviolet blocking
agent and various additives, and then by drying it.
[0029] Further, in the first aid adhesive plaster described in
the above claims, the ultraviolet blocking film is made of the synthetic
resin film containing the ultraviolet blocking agent composed of
titanium oxide, zinc oxide or a processed substance of these, or
the synthetic resin film coated with a layer of the ultraviolet
blocking agent. The ultraviolet blocking film having the ultraviolet
blocking agent evenly on the whole surface thereof is obtained easily
and at a low price by manufacturing a large ultraviolet blocking
film in advance, which is then cut into a number of small ultraviolet
blocking films having the same size and shape as those of a plan
shape of the pad. In addition, the ultraviolet blocking film is
formed to have the same size and shape as the plan shape of the
pad, the whole pad has a structure to block permeation of ultraviolet
rays. Therefore, an influence of the ultraviolet rays to the affected
part like the wound is surely restrained. Furthermore, a curing
effect on the affected part like the wound is accelerated excellently
with the cooperation of the disinfectant titanium oxide or the zinc
oxide.
[0030] Particularly, long wavelength ultraviolet UV-A having a
wavelength of 400 to 320 nm is said to accelerate sunburn and aging
of skin by depositing melanin pigments when the skin is exposed,
and medium wavelength ultraviolet UV-B is said to be a cause of
acute inflammation, immune suppression, skin cancer, spots and freckles
when the skin is exposed. By laying the ultraviolet blocking film
on the pad, which film contains or is coated with the ultraviolet
blocking agent comprising an ultraviolet scattering agent or an
ultraviolet absorber for blocking the UV-A and the UV-B, on the
pad, or by forming the pad to have the layer of the ultraviolet
blocking agent, the affected part like the wound is cured completely
and effectively.
[0031] Further, according to the invention described in the above
claim, the ultraviolet blocking film has a number of small air holes
all over. Therefore, air permeability of the whole pad member is
secured through the small air holes formed in the ultraviolet blocking
film while hardly ruining the ultraviolet blocking function and
without losing air permeability of the pad placed on the affected
part like the wound. In addition, in combination with the adhesive
sheet having the air permeability, the adhesive sheet may be stuck
to the skin including the affected part safely for a long time without
causing a rash.
[0032] According to the structure of the first aid adhesive plaster
described in claim 9, the pad member stuck to the center of the
upper surface of the adhesive sheet is covered with the release
papers stuck onto the adhesive agent layer of the adhesive sheet.
Therefore, when unused, the pad member may be covered and protected
by the release papers for a long time. When used, the release papers
are removed, the pad of the pad member is directly placed on the
affected part like the wound, and the adhesive sheet is stuck to
the skin, whereby the affected part is cured while effectively restraining
the delay in curing of the affected part due to the ultraviolet
rays by means of the ultraviolet blocking film or the ultraviolet
blocking agent layer included in the pad.
[0033] According to the structure of the first aid adhesive plaster,
the ointment is laid on the pad member stuck to the center of the
upper surface of the adhesive sheet. The pad member having the layer
of the ointment is covered with the synthetic resin protecting cover,
which is releasably stuck to the adhesive agent layer of the adhesive
sheet. Therefore, when unused, the ointment laid on the pad of the
pad member is isolated from the outside air by the synthetic resin
protecting cover. Consequently, the ointment is prevented from changing
in its quality and from deteriorating in its effect for a long time.
When used, the protecting cover is removed, the ointment laid on
the pad is placed on the affected part, and the adhesive sheet is
stuck to the skin, whereby the ointment cures the affected part
in a short period of time.
[0034] Further, as mentioned above, the ultraviolet blocking film
disposed on the pad or the ultraviolet blocking agent layer disposed
on the pad prevents the affected part of the skin like the wound
from changing in color or from pigmenting, and effectively restrains
a change in quality of the ointment which may be caused by the ultraviolet
rays. In addition, the ultraviolet blocking film is disposed between
the two pads constituting the pad member, between the pad and the
cushioning material, on the lower surface of the pad, or on the
lower surface of the cushioning material in a state of layers. Therefore,
the ultraviolet blocking film surely prevents the ointment placed
on the pad member from penetrating to reach the adhesive sheet on
the lower surface side of the pad member so that the ointment may
effectively work on the affected part like the wound to cure it.
[0035] Furthermore, as described in the above claims, by laying
the ointment on a part of the net covering the upper surface of
the pad member, which is wholly covered by the net, the ointment
is kept at a predetermined position without coming out of the net
since it is held by the mesh of the pad. In addition, when in use,
the net prevents the pad from directly sticking to the affected
part like the wound by the intermediary of the ointment, whereby
the wound or the like is not damaged when the pad is removed after
use.
[0036] According to the structure of the first aid adhesive plaster,
the capsule body made of synthetic resin, whose bottom opening is
closed by the aluminum foil while encapsulating a liquid medicament
inside thereof, is placed on the pad member stuck to the center
of the upper surface of the adhesive sheet, and the capsule body
is held on the pad member by the release papers stuck to the adhesive
agent layer of the adhesive sheet. Therefore, when unused, the capsule
body is held on the pad member by the release papers. When used,
the aluminum foil closing the bottom opening is broken by giving
a pressure to the capsule body with a fingertip toward the adhesive
sheet for compressive deformation, so that the liquid medicament
inside may penetrate into the pad easily. After that, the release
papers and the capsule body are removed, the pad is placed on the
affected part like the wound, and the adhesive sheet is stuck to
the skin, by which the affected part like the wound may be effectively
disinfected and cured by the liquid medicament.
[0037] Further, as mentioned above, the ultraviolet blocking film
arranged on the pad or the ultraviolet blocking agent layer provided
on/in the pad prevents the affected part of the skin like the wound
from changing in color or from pigment deposit. In addition, by
arranging the ultraviolet blocking film between the two pads, between
the pad and the cushioning material, on the lower surface of the
pad, or on the lower surface of the cushioning material in a state
of layers, the liquid medicament impregnated in the pad of the pad
member is surely prevented from penetrating to reach the lower surface
side of the pad member so that the liquid medicament may effectively
work on the affected part to cure it.
[0038] According to the structure, the influence of the ultraviolet
rays on the liquid medicament or the ointment is eliminated in advance
to suppress the deterioration of the efficiency of the medicine
to the utmost even when the necessary number of the first aid adhesive
plasters are taken out of the storing bag or the storing box to
be carried and are exposed to the sun light frequently, since the
ultraviolet film is laminated with the capsule encapsulating the
liquid medicament or the dome-shaped protecting cover. In this case,
when the ultraviolet blocking film is laminated only with the part
of the capsule contacting the liquid medicament of the part of the
protecting cover contacting the ointment, the part of the lamination
is limited to the minimum and the manufacturing cost is lowered.

MOST PREFERABLE EMBODIMENT OF THE INVENTION
[0058] Now, a specific embodiment of the invention is described
based on the drawings. A first aid adhesive plaster Al as shown
in FIGS. 1 and 2 has the structure that a pad member 3 is stuck
onto the longitudinal center of an adhesive agent layer 2 of an
adhesive sheet 1 having a rectangular shape in plan view, and the
pad member 3 is covered with and is held by two release papers 4,
5 releasably stuck onto the longitudinal both ends of the adhesive
agent layer 2, respectively. The first aid adhesive plaster Al is
used in a manner that the release papers 4, 5 are removed from the
adhesive sheet 1, and the adhesive agent layer 2 of the adhesive
sheet 1 is stuck to a skin in a state that the pad member 3 is in
contact with an affected part like a wound or an insect bite.
[0059] In the first aid adhesive plaster A2 as shown in FIGS. 3
to 5, the pad member 3 is stuck onto the longitudinal center of
the adhesive agent layer 2 of the adhesive sheet 1 having a rectangular
shape in plan view, and the pad member 3 is covered with the two
release papers 4, 5 releasably stuck onto the longitudinal both
ends of the adhesive agent layer 2, respectively. Further, a rectangular
hole 10 is formed in a part of the release paper 4 covering the
pad member 3 so that a capsule body 8, which is made of a synthetic
resin and encapsulates a liquid medicament 11 like a disinfectant
solution, a pain relief medication or a hemostat, may be fitted
to the part of the release paper having the hole 10 in a state of
laminated layers. The capsule body 8 is structured in a manner that
an aluminum foil 9 closes its bottom opening. The aluminum foil
9 is laid over the hole 10, and a projection 12 having a V-letter
shape in cross section is formed downwardly at the center part of
a top face of the capsule body 8.
[0060] When the first aid adhesive plaster A2 is used, first, the
top surface of the capsule body 8 is bent by pressing it downwardly
with the fingertip so that the projection 12 may stick through and
break the aluminum foil 9 and that the liquid medicament 11 encapsulated
in the capsule body 8 may penetrate into the pad member 3 through
the hole 10. Then, the release papers 4, 5 are removed from the
adhesive sheet 1. At this time, the capsule body 8 is removed together
with the release paper 4. Next, the adhesive agent layer 2 of the
adhesive sheet 1 is stuck to the skin in a state that the pad member
3 is in contact with the affected part like the wound or the insect
bite.
[0061] In the first aid adhesive plaster A3 as shown in FIGS. 6
and 7, the pad member 3 is stuck onto the longitudinal center of
the adhesive agent layer 2 of the adhesive sheet 1 with a rectangular
shape. An ointment 6 is laid on the pad member 3, and the pad member
3 having a layer of the ointment 6 thereon is covered with a protecting
cover 7 made of synthetic resin like vinyl chloride resin. Both
across-the-width side edges of the lower opening edge of the synthetic
resin protecting cover 7 are releasably stuck to the adhesive agent
layer 2 of the adhesive sheet 1, and both longitudinal ends of the
adhesive agent layer 2 where the protecting cover 7 is not disposed
are covered with the two release papers 4, 5 releasably stuck onto
the longitudinal ends. Both of the longitudinal ends of the lower
opening edges of the protecting cover 7 are laid on folded opposite
ends 4a, 5a of the release papers 4, 5.
[0062] When using the first aid adhesive plaster A3, the release
papers 4, 5 are removed from the adhesive sheet 1 together with
the protecting cover 7 to expose the pad member 3, and the pad member
3 is brought into contact with the affected part like the wound
or the insect bite. Then, the adhesive agent layer 2 of the adhesive
sheet 1 is stuck to the skin in a state that the ointment 6 laid
on the pad member 3 is in contact with the affected part.
[0063] Any of the three first aid adhesive plasters A1 to A3 as
described above is structured to be used in a manner that the release
papers 4, 5 stuck onto the adhesive agent layer 2 of the adhesive
sheet 1 are removed, and then the adhesive sheet 1 is stuck to the
skin in a state that the pad member 3 adhering to the center of
the upper surface of the adhesive agent layer 2 is in contact with
the affected part of the skin like the wound.
[0064] In these first aid adhesive plasters A1 to A3, the adhesive
sheet I comprises a supporting sheet 1A having a rectangular shape
in plan view and the adhesive agent layer 2 laid on whole of the
upper surface of the supporting sheet 1A. As the supporting sheet
1A, a thin synthetic resin sheet having reasonable flexibility,
elasticity, humid permeability and light permeability, or a rectangular
sheet made of unwoven fabric, woven fabric, paper or the like having
a predetermined width and length is used. As the synthetic resin
sheet, synthetic resins such as olefinic resin like plasticized
polyvinyl chloride, amorphous polyolefin, etc.; polyester-based
resin; ethylene vinyl acetate-based resin; elastomer-based resin;
copolymer of olefinic resin and thermoplastic resin; polymer alloy
of olefinic resin and thermoplastic elastomer; are preferable. In
particular, polyolefin resin, polyester resin, or copolymer of polyolefin-based
resin and thermoplastic elastomer is more preferably used.
[0065] Further, to impart the above-mentioned supporting sheet
1A properties required for a supporting body of the first aid adhesive
plaster like air permeability, moisture permeability, strength,
weather resistance, operability when being stuck, a non-stimulating
property, etc., a sheet having a number of fine air holes all over,
a sheet undergone various processes like embossing finish, uniaxial
stretching, biaxial stretching, annealing or the like, or a sheet
compounded with various additives or fillers, is preferably used.
The additives to be used are, for example, an antioxidant, a light
stabilizer, a heat stabilizer, an antistatic agent, a lubricant,
a flame retardant, a color, or a dye, etc. The fillers to be used
are calcium carbonate, calcium sulfate, titanium oxide, barium sulfate,
magnesium hydroxide, clay or the like. These components are kneaded
by various kinds of kneaders, a banbury mixer or the like, then
heated, melted and kneaded to form resin pellets by using an uniaxial
or biaxial extruder or the like. The pellets are then formed to
be a film, which is then cut into the size of the supporting sheet
1A being the base material of the adhesive sheet 1.
[0066] The adhesive agent laid on the supporting sheet 1A to form
the adhesive sheet 1 is not particularly limited as long as it is
capable of releasably sticking the supporting sheet 1A to the skin,
as long as it has an adhesive force capable of sticking the pad
member 3 to the supporting sheet 1A, and as long as it is safe in
a sense that adhesion to the skin for a long time does not cause
a rash. For example, an acrylic adhesive, a rubber-based adhesive,
a silicon-rubber-based adhesive, a vinyl-ether-based adhesive, or
a urethane-based adhesive may be used.
[0067] The pad member 3 stuck to the center of the upper surface
of the adhesive sheet 1 is the most important structural element
of this invention. The pad member 3 may comprise a pad 31 and an
ultraviolet blocking film 32 laid on the pad 31, as shown in FIGS.
8 to 10. It may also comprise a laminated body of the pad 31, the
ultraviolet blocking film 32 and a cushioning material 35, as shown
in FIGS. 11 and 12, or may also comprise the pad 31, at least one
of the upper layer part or the lower layer part of which is formed
to be an ultraviolet blocking agent layer 36 by impregnating the
layer with an ultraviolet blocking agent.
[0068] The pad 31 forming an important part of the pad member 3
is the laminated body of an unwoven fabric, woven fabric or a disinfected
cloth like a gauze. The pad 3 is formed to be a rectangle in plan
view having a fixed thickness, a width smaller than that of the
adhesive sheet 1 and a length smaller than that of the adhesive
sheet 1. The ultraviolet blocking film 32 is a synthetic resin film
like a polyester film containing the ultraviolet blocking agent
comprising an ultraviolet dispersing agent or an ultraviolet absorbing
agent or comprising both of these agents, or a synthetic resin film
like a polyester film having the ultraviolet blocking layer provided
by coating its surface with the ultraviolet blocking agent. The
ultraviolet blocking film 32 is formed to be a rectangle having
a substantially same size as the pad 31. In the meantime, a thickness
of the synthetic resin film is not particularly limited, however,
about 1 to 500 .mu.m is preferable, and in particular, about 1 to
20 .mu.m is preferably used.
[0069] The pad member 3 having the ultraviolet blocking layer 34
on the pad 31 and without having the ultraviolet blocking film 32
is prepared as follows. Namely, the upper layer part or the lower
layer part of the pad 31 is coated with or impregnated with the
suspension liquid or the paste of the ultraviolet blocking agent
comprising the ultraviolet dispersing agent or the ultraviolet absorbing
agent, and various additives. The pad 31 is then heated and dried
to make the pad member 3. The pad member 3 may also be prepared
in a manner that the upper layer part or the lower layer part of
the pad 31 is coated with a dispersion liquid of the ultraviolet
blocking agent and the additives, and it is heated and dried.
[0070] The ultraviolet blocking agent means the substance or combination
of the substances that substantially blocks the ultraviolet rays
in a ultraviolet range of UV-B (wavelength of 320 to 290 nm) to
UV-A (wavelength of 400 to 320 nm). As such substances, both of
the ultraviolet dispersing agent for blocking permeation of ultraviolet
rays to the affected part or a medicament by dispersing the ultraviolet,
and the ultraviolet absorbing agent for blocking permeation of ultraviolet
to the affected part or to the medicament by absorbing rays of the
wavelength in the ultraviolet range, may be used. To substantially
block the ultraviolet rays means to block the ultraviolet rays to
suppress the optical transparency of the ultraviolet range of UV-B
to UV-A not to ruin the object of the invention, and a preferable
ultraviolet cutting ratio is 95% or more, and more preferably it
is 98% or more.
[0071] The ultraviolet dispersing agent is not particularly limited
as long as it prevents the ultraviolet rays from permeating, by
dispersing and reflecting the ultraviolet rays in a physical mechanism.
To be specific, for example, substances as mentioned below are preferably
used. Namely, titanium oxide, zinc oxide, black iron oxide, yellow
iron oxide, kaolin, talc, magnesium silicate, magnesium oxide, light
(settled) magnesium carbonate, heavy magnesium carbonate, a substance
made by converting these into ultra-fine particles, and in particular,
titanium oxide, zinc oxide or titanium oxide covered with clay mineral,
titanium oxide containing iron, and treated substances like fine
particles of zinc oxide or of titanium oxide, are preferably used.
These ultraviolet dispersing agents may be used in proper combination
with the other ultraviolet dispersing agents or the other ultraviolet
absorbing agents taking the characteristic of each of the substances
into consideration. A preferable average particle diameter, at one
time, of the particles of these substances applied to the ultraviolet
blocking first aid adhesive plaster is about 0.001 to 30 .mu.m,
and about 0.01 to 20 .mu.m is particularly preferable.
[0072] The ultraviolet absorbing agent is not particularly limited
as long as it absorbs energy through a chemical mechanism, turns
it into the energy like heat to prevent permeation of ultraviolet
rays. To be specific, various kinds of ultraviolet absorbing agents
may be used like a salicylic acid-based ultraviolet absorbing agent
like salicylic acid 2-ethylhexyl (octyl) absorbing UV-B, a benzophenone-based
ultraviolet absorbing agent like oxybenzone absorbing UV-B to UV-A
of short wavelength, a cinnamic acid-based ultraviolet absorbing
agent like p-methoxycinnamic acid2-ethylhexyl (oxtyl) absorbing
UV-B, a benzotriazole-based ultraviolet absorbing agent like 2-(2-hydroxy-5-methylphenyl)
benzotriazol, a cyanoacrylate-based ultraviolet absorbing agent
like salicylic acid 2-ethylhexyl, (2-ethylhexyl-2-cyano-3,3-diphenyl
acrylate, paraminobenzoic acid, octyl p-dimethylaminobenzoate, salicylic
acid homosalate, etc.
[0073] The above-mentioned ultraviolet blocking film 32 containing
such ultraviolet blocking agent in it or coated with the ultraviolet
blocking agent is manufactured in a manner as mentioned below. Namely,
for example, the ultraviolet blocking film containing the ultraviolet
blocking agent in it is obtained in a manner that the ultraviolet
blocking agent is mixed into the dispersion liquid like an aqueous
dispersion liquid of polyolefin-based resin such as polyethylene-based
thermoplastic resin together with various kinds of additives, which
is then heated, kneaded, formed to be the film, cooled and hardened,
or cross-linked.
[0074] The ultraviolet blocking film 32 coated with the ultraviolet
blocking agent is obtained as follows. Namely, for example, the
dispersion liquid like the aqueous dispersion liquid of polyolefin-based
resin such as polyethylene-based thermoplastic resin and various
additives are mixed without adding the ultraviolet blocking agent,
which are heated, kneaded, formed to be film-like, cooled and hardened
or cross-linked to obtain a resin film. The surface of the resin
film is then coated with a liquid substance including the ultraviolet
blocking agent by using a calendar roller or the like. The ultraviolet
blocking film 32 is also obtained by incorporating the ultraviolet
blocking agent with polyester-based urethane resin and vinyl acetate
chloride copolymer resin, and dispersion liquid incorporated with
the various additives is printed on the synthetic resin film by
a gravure coater, which is than dried.
[0075] It is preferable that a number of small air holes 13 are
formed in the ultraviolet blocking film 32 all over to impart good
air permeability and moisture permeability. Preferable diameter
of the small air holes 13 is about 50 to 70 .mu.m and the preferable
number of the holes 13 is about 1 to 15/cm.sup.2.
[0076] Now, various structures of the pad member 3, being the most
important element of the invention, are explained hereinafter. The
pad member 3A shown in FIG. 8 is the laminated body of a sheet of
the pad 31 made of the gauze, the unwoven fabric, the woven fabric
or the like having a fixed thickness, and the ultraviolet blocking
film 32. The pad 31 is laminated on the ultraviolet blocking film
32, which laminated body is wrapped with the net 34 made of the
thermoplastic synthetic resin like polyethylene, and the net 34
is fixed to the lower surface of the ultraviolet blocking film 32
by means of heat welding or a proper adhesive agent. The pad member
3A is arranged on the adhesive sheet 1 in a manner that the lower
surface of the net 34 covering the ultraviolet blocking film 32
is stuck onto the longitudinal center of the adhesive agent layer
2 of the adhesive sheet 1 with the ultraviolet blocking film 32
of the pad member 3A facing down. The net 34 may be netted with
a string-like object made of a material other than the thermoplastic
synthetic resin.
[0077] The pad member 3B shown in FIG. 9, comprises the laminated
body of two pads 31, 31, which is made of the gauze, the unwoven
fabric or the woven fabric and has a fixed thickness, and the ultraviolet
blocking film 32. The laminated body, in which the ultraviolet blocking
film 32 is laid under the lower surface of the lower pad 31 of the
two laminated pads 31, 31, is wrapped with the net 34. Both ends
of the net 34 are fixed to the lower surface of the ultraviolet
blocking film 32 by means of heat welding or with the proper adhesive
agent. The lower surface of the net 34 covering the ultraviolet
blocking film 32 arranged on the lower side of the pad member 3B
is stuck onto the adhesive agent layer 2 at the longitudinal center
of the adhesive sheet 1.
[0078] The pad member 3C shown in FIG. 10 comprises the laminated
body of the two pads 31, 31 and the ultraviolet blocking film 32
interposed between them, and the net 34 wrapping the laminated body.
Both ends of the net 34 is fixed to the lower surface of the lower
pad 31 by means of heat welding or a proper adhesive agent. The
pad member 3C is disposed on the adhesive sheet 1 by sticking the
lower surface of the net 34 covering the lower pad 31 of the pad
member 3C onto the adhesive agent layer 2 at the longitudinal center
of the adhesive sheet 1. In the pad members 3B and 3C shown in FIGS.
9 and 10, the number of the pads 31 is not limited to two but may
be three or more.
[0079] The pad member 3D shown in FIG. 11 comprises the laminated
body of the ultraviolet blocking film 32, the cushioning member
35 laid thereon and the pad 31 further laid thereon in this sequence,
and the net 34 wrapping the laminated body. Both lower ends of the
net 34 are fixed to the lower surface of the ultraviolet blocking
film 32 disposed on the lower surface of the cushioning material
35 by means of heat welding or with the proper adhesive. The pad
member 3D is disposed on the adhesive sheet 1 by sticking the lower
surface of the net 34 onto the adhesive agent layer 2 at the longitudinal
center of the adhesive sheet 1.
[0080] The pad member 3E shown in FIG. 12 comprises the laminated
body of the pad 31, the cushioning material 35 made of foamed synthetic
resin and having the same shape as the pad 31 and the fixed thickness,
the ultraviolet blocking film 32 interposed between the pad 31 and
the cushioning material 35, and the net 34 wrapping the laminated
body. Both lower ends of the net 34 is fixed to the lower surface
of the cushioning material 35 disposed on the lower side of the
pad 3E by means of heat welding or the proper adhesive. The lower
surface of the net 34 is stuck onto the adhesive agent layer 2 at
the longitudinal center of the adhesive sheet 1.
[0081] Each of the pad members 3A, 3B and 3C comprising the laminated
body formed by combining the pad 31 and the ultraviolet blocking
film 32 is laminated simply by laying one on the other without sticking
the pad 31 to the ultraviolet blocking film 32. Therefore, it comes
apart and may not be disposed on the adhesive sheet 1 as it is.
To solve the problem, the net 34 covers the laminated body of the
pad 31 and the ultraviolet blocking film 32 from the upper surface
of the pad 31 to extend to both sides of the laminated body, and
both lower ends of the net 34 extend and are folded to the lower
surface of the laminated body, which ends are fixed to the lower
surface of the laminated body by means of heat welding or the proper
adhesive so that a form of the laminated body may be maintained
by wrapping the laminated body with the net in this manner.
[0082] When in use, the net 34 prevents the pad 31 of each of the
pad members 3A, 3B, and 3C from tightly adhering to the affected
part of the skin like the wound. The net 34 is placed on the affected
part when in use, and after use, the net 34 is capable of being
removed without damaging the wound or the like. However, when the
pad 31 and the ultraviolet blocking film 32 are laminated and stuck
together, the net 34 is not necessarily needed.
[0083] Similarly, in each of the pad members 3D and 3E comprising
the pad 31, the ultraviolet blocking film 32 and the cushioning
material 35, the pad 31, the ultraviolet blocking film 32 and the
cushioning material 35 are also laid simply without being stuck
together. Therefore, the pad 31 comes apart and may not be disposed
on the adhesive sheet 1 as it is. To solve the problem, the net
34 covers the laminated body of the pad 31 and the ultraviolet blocking
film 32 from the upper surface of the pad 31 to extend to both sides
of the laminated body, and both lower ends of the net 34 extend
and are folded to the lower surface of the laminated body, which
ends are fixed to the lower surface of the laminated body by means
of heat welding or the proper adhesive so that a form of the laminated
body may be maintained by wrapping the laminated body with the net
in this manner. Further, similarly to the pad members 3A, 3B and
3C, the net 34 prevents the pad 31 from being directly and firmly
attached to the affected part of the skin when in use. However,
when the pad 31, the cushioning material 35 and the ultraviolet
blocking film 32 are laminated and stuck together, the net 34 is
not necessarily needed.
[0084] Each of the pad members 3F and 3G shown in FIG. 13 and 14
is structured to have the ultraviolet blocking function without
using the ultraviolet blocking film 32. Namely, the pad member 3F
shown in FIG. 13 comprises a pad 31 and the ultraviolet blocking
layer 36, which is made in a manner that the lower layer part of
the pad 31 is coated with or impregnated with the ultraviolet blocking
agent comprising the suspension liquid or the paste including the
ultraviolet dispersing agent or the ultraviolet absorbing agent,
and the various additives, which is then heated and dried. The pad
member 3G shown in FIG. 14 comprises the ultraviolet blocking layer
36 provided on the lower layer part of the lower pad 31 of the two
pads 31, 31. The ultraviolet blocking layer 36 is made in a manner
that the lower layer part of the lower pad 31 is coated with or
impregnated with the ultraviolet blocking agent comprising the suspension
liquid or the paste including the ultraviolet dispersing agent or
the ultraviolet absorbing agent, and the various additives, which
is then heated and dried.
[0085] By wrapping the pad 31 with the net 34, these pad members
3F and 3G maintain their forms of lamination. Each of the pad members
3F and 3G, is made by fixing both lower ends of the net 34 to the
lower surface of the lower pad 31 by means of heat welding or the
proper adhesive. Each of them is disposed on the adhesive sheet
1 by sticking the lower surface of the net 34 onto the adhesive
agent layer 2 at the longitudinal center of the adhesive sheet 1.
[0086] Each of the pad members 3A to 3G shown in FIGS. 8 to 14
is used as the pad member 3 of the first aid adhesive plaster A1
shown in FIGS. 1 and 2, or of the first aid adhesive plaster A2
shown in FIGS. 3 to 5. In the first aid adhesive plaster A1 in which
the pad member 3 is directly covered with the release papers 4,
5, the release papers 4, 5 are removed from the adhesive sheet 1
when used to expose the pad member 3, and then the adhesive sheet
1 is stuck to the skin while placing the pad member 3 on the affected
part like the wound. When the first aid adhesive plaster A2 in which
the capsule body 8 encapsulating the liquid medicament is provided
on the pad member 3 is used, first, the bottom surface made of the
aluminum foil 9 of the capsule body 8 is broken by the projection
12 projecting downwardly from the top face of the capsule body 8
by pressing the top face downwardly with the finger tip to impregnate
the pad 31 of the pad member 3 on the lower side with the liquid
medicament in the capsule body 8. Then the release paper 4 having
the capsule body 8 and the other release paper 5 are removed, and
then the adhesive sheet 1 is stuck to the skin while the pad member
3 is placed on the affected part like the wound.
[0087] At this time, when the pad member 3 is any one of the pad
members 3A to 3C comprising the pad 31 and the ultraviolet blocking
film 32, the ultraviolet blocking film 32 is stuck to the lower
side of the pad member 3, in other words, to the side of the adhesive
agent layer 2 of the adhesive sheet 1, or is interposed between
the two pads 31, 31. Consequently, the pad 31, which is soft, is
placed on the affected part like the wound via the net 34, and the
affected part like the wound is not damaged. In addition, by forming
a number of small air holes 13 in the ultraviolet blocking film
32 all over substantially evenly, the rash is prevented from developing
on the affected part of the skin in cooperation with the air permeability
of the adhesive sheet 1 and the pad 31.
[0088] In each of the pad members 3D and 3E comprising the laminated
body of the pad 31, the ultraviolet blocking film 32 and the cushioning
material 35, in addition to the effect of the pad members 3A to
3C wherein the pad member 3 comprises the pad 31 and the ultraviolet
blocking film 32, the pad 31 may be softly pressed against the affected
skin like the wound with a moderate elasticity and without imparting
a feeling of pressure because of the existence of the cushion member
35 arranged on the lower side of each of the pad members 3D, 3E.
[0089] Further, in any of the pad members 3, the ultraviolet rays
penetrate through the adhesive sheet stuck to the skin, however,
the ultraviolet blocking film 32 included in the pad member 3 restrains
the ultraviolet rays from penetrating to the affected part like
the wound, wherefore, change in the skin color or the deposit of
pigment is prevented. In the meantime, in the pad members 3F, 3G
shown in FIGS. 13 and 14 wherein the ultraviolet blocking layer
36, instead of the ultraviolet blocking film 32, is included in
the upper or lower layer part of the pad 31, the ultraviolet blocking
layer 36 prevents the ultraviolet rays, which penetrates through
the adhesive sheet 1, from penetrating to the affected part.
[0090] When the pad members 3A to 3G shown in FIG. 8 to 14 are
used as the pad member 3 in the first aid adhesive plaster A3 shown
in FIGS. 6, 7, the ointment 6 is placed on the uppermost pad 31
of the pad member 3 stuck to the adhesive agent layer 2 of the adhesive
sheet 1. For example, the pad member 3H shown in FIG. 15 is formed
in a manner that the layer of the ointment 6 is placed on the uppermost
pad 31 of the pad member 3C, shown in FIG. 10, which is formed by
wrapping the laminated body, comprising two pads 31, 31 and the
ultraviolet blocking film 32 interposed between them, with the net
34. The pad member 31 shown in FIG. 16 is formed by placing the
ointment 6 on the uppermost pad 31 of the pad member 3G shown in
FIG. 14 comprising two pads 31, 31 and the ultraviolet blocking
member 36 provided on the lower layer part of the lower pad 31.
[0091] In this manner, the pad member 3 having the layer of the
ointment 6 on its surface is covered with the synthetic resin protecting
cover 7, and both side edges of the lower opening edge of the protecting
cover 7 are stuck onto the adhesive agent layer 2 of the adhesive
sheet 1 at both long sides thereof. Both or the longitudinal lower
edges of the protecting cover 7 are laid on opposite ends 4a, 5a
of the release papers 4, 5 stuck to both of the longitudinal end
parts of the adhesive agent layer 2 where the protecting cover 7
is not disposed.
[0092] The ointment 6 is laid on the pad 31 of the pad member 3
through the mesh of the net 34 covering the pad 31. Therefore, the
ointment 6 is held by the mesh of the net 34 so that it may not
flow out of the pad. In addition, even when the components of the
ointment 6 penetrate into the pad 31 by capillarity, the ultraviolet
blocking film 32 prevents the components from penetrating to the
side of the adhesive sheet 1 in the pad member 3H shown in FIG.
15. In the pad member 31 wherein the ultraviolet blocking layer
36 is included in the pad 31 instead of the ultraviolet blocking
film 32, a surface boundary between the upper and lower pads 31,
31 restrains the components of the ointment 6 from penetrating to
the lower pad 31.
[0093] When the first aid adhesive plaster A3 is used, the release
papers 4, 5 and the protecting cover 7 is removed from the adhesive
sheet 1 to expose the pad member 3, and the adhesive sheet 1 is
stuck to the skin in a state that the ointment 6 laid on the pad
is put on the affected part like the wound. The effects of the ultraviolet
blocking film 32 and the ultraviolet blocking layer 36, and the
function of the net 34 in this state of use are already described
above.
[0094] The pad member 3J shown in FIG. 17 comprises two pads 31,
31, an ointment penetration restraining film 33 having the laminated
body comprising a piece of paper or a flexible synthetic resin sheet
having the same shape in plan view as the pad 31 and being interposed
between the pads 31, 31, and the ultraviolet blocking film 32 layered
on the lower surface of the pad 31 of the lower layer side, and
the net 34 wrapping the laminated body. The ointment penetration
restraining film 33 prevents the ointment from penetrating to the
lower layer side. Since the other part of the structure is the same
as the above-mentioned pad member 3, detailed explanation is omitted.
[0095] Next, another embodiment of the invention is explained in
detail based on FIGS. 18 and 19. Here, the first aid adhesive plaster
is covered by the ultraviolet blocking film. Namely, the main purpose
is that the ultraviolet blocking film 32 prevents hindrance in regeneration
of the skin caused by application of ultraviolet rays to the affected
part after the first aid adhesive plaster is stuck thereto. In the
meantime, the first aid adhesive plaster is not necessarily stored
in a box or a case, but in many cases, the necessary number of the
first aid adhesive plasters are taken out of the case, carried and
then are used.
[0096] In these cases, the first aid adhesive plaster is carried
in a state that the capsule body 8 as shown in FIGS. 3, 4 is exposed
or that the dome-shaped synthetic resin protecting cover 7 as shown
in FIG. 6 is exposed. In such case, the ultraviolet rays penetrates
through the capsule body 8 or the synthetic resin protecting cover
7 and the liquid medicament 11 inside the capsule body 8 as shown
in FIG. 3 or the ointment 6 as shown in FIG. 6 may be changed in
the quality. It is preferable to eliminate such events in advance.
[0097] Here, as shown in FIG. 18, the ultraviolet blocking film
is applied to the synthetic resin capsule body 8 shown in FIGS.
3 and 4. In this embodiment, the same ultraviolet blocking film
32' as the above mentioned one is laminated with the sheet for making
the capsule body 8 before the capsule body 8 encapsulating the liquid
medicament 11 is formed. The capsule body 8 is laminated and coated
integrally with the ultraviolet blocking film 32' having a thickness
of about 25.mu. to 100.mu.. The ultraviolet blocking film 32' is
the synthetic resin film like polyester as described above in detail.
[0098] Further, as shown in FIG. 19, the synthetic resin protecting
cover 7 as shown in FIG. 6 is coated integrally with the ultraviolet
blocking film 32'. The ultraviolet blocking film 32' is the same
synthetic resin film like the polyester as the one described above
in detail. The ultraviolet blocking film 32' is laminated with and
stuck to the inside of the sheet (to be inside of a dome) before
it is formed to be a dome. The synthetic resin protecting cover
7, formed with vinyl chloride resin or the like having close compatibility
and is capable of being welded, is heat-welded. However, it may
be stuck by using an adhesive agent. The ultraviolet blocking film
32' may be laminated on the outside of the front/rear side of the
synthetic resin protecting cover or on both sides thereof.
[0099] As mentioned above, even when the first aid adhesive plaster
is taken out of the storing case or the box to be carried and is
exposed to the sun light, the ultraviolet blocking film 32' eliminates
the influence of the ultraviolet rays on the liquid medicament 11
inside the capsule body 8 or on the ointment 6 inside the synthetic
resin protecting cover 7.
[0100] This invention may be applied to various forms of first
aid adhesive plasters like a liquid medicament type using the capsule,
an ointment type using a dome-shaped cover. Therefore, The first
aid adhesive plaster is versatile as a plaster in an emergency medical
care. |
