Patent Description
[0001] This application is a continuation-in-part and claims priority
of utility application Ser. No. 10/750,286, filed Dec. 31, 2003,
which in turn claims priority of provisional application Ser. No.
60/437,476, filed Jan. 2, 2003.
BACKGROUND
[0002] This invention. relates substantially to air fresheners
which release a scent or absorb a scent in a confined space and
more particularly to a thin planar air freshener which can be applied
to a substantially flat surface (i.e. glass, metal, plastic, etc.).
[0003] Confined spaces often develop an odor which can be less
than pleasant. Kitchens, bathrooms, automobile interiors, lockers
and other spaces often suffer from odor problems. In the past, people
have addressed these odor problems by positioning air fresheners
which release a scent into these spaces. Another approach has been
taken with smaller spaces such as closed lockers or refrigerators.
Refrigerators and lockers, for example, sometimes develop an odor
based upon some of the food ingredients or gear stored therein.
One remedy used with refrigerators is the positioning of an opened
box of baking soda in the refrigerator, the thought being that the
baking soda absorbs the offensive odor.
[0004] Prior approaches have shortcomings. An easily visible air
freshener, in some situations, can be viewed as a statement that
there is an odor problem in the space involved. Moreover, some air
fresheners have a less than pleasing appearance to many people.
Particularly in an automobile or locker setting, an air freshener
needs to be retained in place because of the motion of the automobile
(or a door of a locker) and replaceable when exhausted. These requirements
and the requirement for a pleasing appearance are somewhat contradictory.
SUMMARY
[0005] The present invention provides an air freshener which is
planar and unobtrusive resembling, for example, a parking or club
membership decal and which is easily retained in place and easily
removed when exhausted.
[0006] Yet further in accordance with the invention, a non-adhesive
planar air freshener is provided comprising a flexible static cling
sheet having an adhesive free first face to selectively removably
cling to a glass surface, a second face, a first dimension, a second
dimension and a footprint. A static cling free sheet is provided
having a first face adhered to the static cling sheet and a second
face, the static cling free sheet has a first dimension, a second
dimension and a footprint. The static cling free sheet has a first
dimension, a second dimension and footprint identical to the static
cling sheet first dimension, second dimension and footprint. An
adhesive sheet is provided having an adhesive first face, an adhesive
second face, a first dimension smaller than the static cling sheet
first dimension and a footprint smaller than the static cling first
sheet, the adhesive sheet first face being adhered to the static
cling free sheet second face. A planar fragrance member is provided
having a first face, a second face, a first dimension equal to the
adhesive sheet first dimension, a second dimension and a footprint.
The fragrance member carries a fragrance adapted to emit a scent
into a surrounding atmosphere, the fragrance member first face being
fixed to the adhesive sheet second face. The fragrance member can
have a printed design on the first face and the second face and
can be selected from the group consisting of a fiberboard sheet,
a cardboard sheet, and a paper sheet. The fragrance member emits
increased fragrance when heated and emits decreased fragrance when
cooled. The fragrance member is printed in a pattern including dark
inks whereby the fragrance member performs the duty of distinguishing
the air freshener as a decal and the duty of automatically variably
activating the air freshener. Additionally, a metering sheet is
provided having a first face, a second face, a first dimension,
a second dimension and a footprint. The metering sheet first face
is fixed to at least one of the static cling free sheet, the adhesive
sheet and the fragrance member such that at least a portion of the
metering sheet first face is in contact with the fragrance member
second face. The metering sheet is adapted to allow passage of the
scent at a selected rate.
[0007] In accordance with the invention, a non-adhesive planar
air freshener is provided comprising a flexible static cling polymer
layer having an adhesive free first face to selectively removably
cling to a surface, a second face, a first dimension, a second dimension
and a footprint. A graphic sheet is provided having a first face,
adhered to the static cling polymer layer, and a second face. The
graphic sheet has a first dimension, a second dimension and a footprint.
The graphic sheet first dimension, a second dimension and footprint
being substantially the same as the static cling polymer layer first
dimension, second dimension and footprint. A fragrance member is
provided having a first face, a second face, a first dimension equal
to the graphic sheet first dimension, a second dimension and a footprint.
The fragrance member carries a fragrance adapted to emit a scent
into a surrounding atmosphere, the fragrance member first face being
fixed to the graphic sheet second face. The fragrance member is
adapted to emit the scent at a selected rate partially based upon
temperature.
[0008] Yet still further in accordance with the invention, a removable
non-adhesive planar air freshener is provided comprising a first
planar member having an adhesive free static cling first face to
selectively removably cling to a surface, a second face, a first
planar dimension, a second planar dimension and a footprint. A planar
display sheet is further provided having a first face, a second
face and a footprint. The display sheet first face is permanently
fixed to the first planar member second face and can bear a printed
design. A planar fragrance member is also provided having a uniform
thickness, a first face, a second face, a first planar dimension,
a second planar dimension and a footprint. The fragrance member
first face is in contact with the display sheet second face. The
fragrance member is a body of cured liquid polymer and impregnated
with a scent.

DETAILED DESCRIPTION
[0023] Referring now to the drawings wherein the showings are for
the purposes of illustrating an embodiment of the invention and
not for the purposes of limiting same, FIG. 1 shows an air freshener
10 in accordance with an embodiment of the invention. The front
view or side 12 of the air freshener 10 is seen in FIG. 1. The front
side 12 is the side that can be seen from the outside of an automobile
when the air freshener is applied to the inside surface of the windshield
of an automobile. The front side 12 comprises a central printed
area 14f surrounded by a transparent margin 16. The central printed
area 14f can be provided with a design, possibly including words
and serial numbers, simulating a parking sticker or club membership
decal of the type frequently seen on automobile windshields. The
central area 14f can be surrounded by a transparent margin 16 which
can appear to be transparent plastic. Of course, the margins 16
could be translucent or even opaque so long as the central printed
area 14f and its design are visible at the front side 12.
[0024] Referring now to FIG. 2, a back view or side 18 of the air
freshener 10 is shown. Some of the structural elements of the back
side 18 are emphasized in FIG. 2 for purposes of clarity. In use,
the back side 18 can have a resemblance similar to the front side
12. That is, a back face central printed area 14b is surrounded
by the transparent margin 16. The back face central printed area
14b is preferably opaque with a printed legend thereon either identical
to the printed legend on the front face central printed area or,
as shown, different from the front face printed area 14f. Of course,
the back face central printed area 14b could be left opaque and
blank without departing from the spirit of the invention.
[0025] Thus, the appearance of the air freshener 10 from both the
front view 12 and the back view 18 strongly resembles a parking
or membership decal as is frequently seen on the inside of an automobile
windshield.
[0026] The elements used to construct the air freshener 10 are
seen in FIG. 6. A static cling or first sheet 20 is the frontmost
element of the air freshener 10. A protective backing or cover 22
can be provided to protect the static cling sheet 20 from contaminants
until installation is desired and/or between installations. The
protective cover 22 can help to preserve the static cling properties
of the static cling sheet 20. The static cling sheet 20 can be generally
rectangular with rounded corners and include a width or first planar
dimension 20 w and a height or second planar dimension 20 h. Along
with a footprint 20A generally defined as the product of the width
dimension 20 w and the height dimension 20 h (20 w.times.20 h).
The static cling sheet 20 can be a uniformly thin sheet, typically
2 to 6 mils, and is selected to have static cling properties on
its front or first face 20f. Certain films, such as certain vinyl
films and certain polyvinyl chloride films are known to cling to
glass surfaces without the need of an adhesive. The static cling
characteristic of plastic film and sheets has been used in the past
for products such as food wrap.
[0027] A barrier or static cling free sheet 24 is provided with
an adhesive on its front or first face 24f (the face facing the
static cling sheet 20), a width or first dimension 24 w and a height
or second dimension 24 h. The width dimension 24 w and height dimension
24 h of the barrier sheet 24 can be identical to the width 20 w
and height dimension 20h, respectively, of the static cling sheet
20. The barrier sheet 24 can be generally rectangular with round
corners and have a footprint 24A identical to the footprint 20A
of the static cling sheet 20. The barrier sheet 24 can be permanently
fixed, by means of the adhesive on its front face 24f, to a back
or second face 20b of the static cling sheet 20 in registry with
the static cling sheet 20.
[0028] An adhesive sheet 26 is provided with an adhesive on both
its front or first face 26f and its back or second face 26b. The
adhesive sheet 26 has a width or first dimension 26 w slightly smaller
than the width dimension 20 w of the static cling sheet 20 and a
height or second dimension 26 h slightly smaller than the height
dimension 20h of the static cling sheet 20. The adhesive sheet 26
can be fixed to the center of the back or second face 24b of barrier
sheet 24. The adhesive sheet 26 can be generally rectangular with
round or square corners and have a foot print 26A generally defined
as the product of the width dimension 26 w and the height dimension
26 h (26 w.times.26 h).
[0029] A fragrance board or planar fragrance member 28 can be a
thin fiberboard, paperboard or paper rectangle having a width or
first planar dimension 28 w and a height or second planar dimension
28 h. The width dimension 28 w and the height dimension 28 h of
the fragrance board 28 can be identical to the width 26 w and height
dimensions 26 h, respectively, of the adhesive sheet 26. The fragrance
board 28 can be generally rectangular with round or square comers
and have a foot print 28A generally defined as the product of the
width dimension 28 w and the height dimension 28 h (28 w.times.28
h). The fragrance board 28 is preferably 65 mils or less thick.
The fragrance board 28 can be opaque and printed with a design on
both its front or first face 28f, which forms the central printed
area 14f, and its rear surface, which forms the back or second face
28b central printed area 14b. The fragrance board 28 is shown in
FIG. 6 without printing for purposes of clarity. The fragrance board
28 can be porous. The fragrance board 28 carries a quantity of fragrance,
shown in FIG. 6 schematically as fragrance drops 29. The fragrance
29 is applied as a liquid and is volatile giving off a scent when
exposed to air. The fragrance 29 is absorbed into the substance
of the fragrance board 28 relatively uniformly and will not be visible
as drops 29.
[0030] A thin plastic metering sheet 30 is provided with adhesive
on the front or first face 30f facing the fragrance board 28. The
metering sheet is provided with a non-adhesive back or second face
30b for ease of handling and placement to a desired location. The
metering sheet 30 can be rectangular with a width or first dimension
30 w identical to the width dimension 28 w of the fragrance board
28 and a height dimension exceeding the height dimension 28 h of
the fragrance board 28 and (an applied height or second dimension
30 h) identical to the height dimension 20 h of the static cling
sheet 20. The metering sheet 30 can be generally rectangular with
round or square comers and have a foot print 30A generally defined
as the product of the width dimension 30 w and the height dimension
30 h (30 w.times.30 h). The metering sheet 30 can be provided with
a multiplicity of through holes 31. In the embodiment shown, the
metering sheet 30 is provided with 48 holes arranged as six rows
of eight holes each. The number and size of the holes 31 are selected
to provide an appropriate release rate for the fragrance 29 from
the fragrance board 28.
[0031] The static cling sheet 20, the barrier sheet 24, the adhesive
sheet 26 and the metering sheet 30 can be all fabricated from thin
transparent plastic film. Moreover, all of these films can be flexible.
The fragrance board 28 can be fabricated from fiberboard, paperboard
or paper depending upon the amount of and type of fragrance 29 to
be carried in the product and the desired thickness. A larger amount
of fragrance can be carried in a thicker board. A thinner paper
fragrance board will be more flexible and can be used with concentrated
fragrances which do not require much volume.
[0032] The barrier sheet 24 can be fabricated from a plastic film
selected to be impervious to the adhesives used and to the fragrance
carried by the fragrance board 28. It protects the vinyl cling sheet
20 from possible attack by the fragrance.
[0033] As shown in FIGS. 1 and 2, the fragrance board 28 is preferably
printed on both sides 28f, 28b to resemble a parking or membership
sticker. Paper, cardboard and fiberboard are easily printed. None
of the other layers of the air freshener 10 needs to be printed.
None of the other layers of the air freshener 10 need to be colored
in any way.
[0034] The adhesive sheet 26 may be replaced by an adhesive layer
(not shown) applied to a portion of the barrier sheet 24 or the
fragrance board 28.
[0035] The barrier sheet 24 provides the advantage of protecting
the static cling sheet 20 from attack by the adhesives used in other
layers 26, 30 and from attack by the fragrance 29. If a fragrance
29 is selected which will not attack the static cling sheet 20,
it may be possible to dispense with the barrier sheet 24. However,
the barrier sheet 24 also masks the static cling sheet 20 from the
interior of the automobile. This prevents the second face 20b of
the static cling sheet 20 from drawing and holding dust and other
dirt elements and having a dirty appearance.
[0036] As can be seen in FIG. 5, the metering sheet 30 lays against
the barrier sheet 24 in the margin areas 16. The metering sheet
30 also lays against top and bottom edges 32, 34 of the fragrance
board 28 and the back face 28b of the fragrance board 28. Because
of this, the unapplied metering sheet 30 will have a height dimension
(not illustrated) slightly greater than height dimension 20 h of
the static cling sheet 20 so that its `as applied` height dimension
30 h is equal to the height dimension 20 h of the static cling sheet
20 and barrier sheet 24.
[0037] A location for mounting the air freshener 10 is near the
lower left corner of an automobile windshield. In this position,
the air freshener 10 is exposed to sunlight on warm sunny days.
The sunlight will have little effect on the transparent layers of
the air freshener 10. The fragrance board 28 can be opaque and,
preferably contains darkly colored areas. Sunlight will penetrate
through a transparent automobile windshield and the transparent
film layers of the air freshener 10 and illuminate and heat the
fragrance member. The heated fragrance member will release fragrance
into the automobile interior at an increased rate when compared
to a cold air freshener as most volatile materials evaporate more
quickly when heated. The air freshener is, thus, sunlight activated.
On the other hand, in a northern winter, the air freshener will
be `deactivated` when a car is parked in a cold garage overnight.
The air freshener will be reactivated when the driver turns on the
heat, raising the temperature in the car interior. Thus, the air
freshener 10 is automatically activated, at a variable rate, as
needed only, extending its useful life.
[0038] With reference to FIG. 7, an air freshener formed in accordance
with a second embodiment is illustrated. Like components are identified
with like numerals including a primed (') suffix and new components
are identified with new numerals. As an alternative to the cardboard
fragrance board 28 in an air freshener 10', a thin rectangular block
or odor abating member 38 of baking soda in a binder can be held
in place by the metering sheet 30' (see FIG. 7). A front or first
face 38f of the odor abating member 38 can be in registry with an
adhesive second face 36b of an adhesive or planar display sheet
36. A back or second face 38b of the odor abating member 38 can
be in registry with the adhesive first face 30'f of the metering
sheet 30'. The binder can be porous allowing the passage of air
through the holes 31', whereby odors in the air can be extracted
and held in the block of baking soda. Similar to the fragrance board
28, the odor abating member 38 can be planar having a width or first
dimension and a height or second dimension defining a footprint.
This embodiment is particularly applicable to refrigerators. In
this embodiment, the adhesive sheet 36 can be provided with a printed
design on a front or first face 36f and function as a planar display
sheet. The planar display sheet 36 can have a footprint similar
to the footprint of the odor abating member 38.
[0039] Air fresheners 10,10' can be packaged in an airtight retail
package such as a rib and groove closure plastic bag or a blister
pack (not shown). In this way, the fragrance is contained on the
fragrance board 28 (and odor abating member 38 preserved) until
the package is opened by the consumer and the air fresheners 10,10'
applied to the desired location. Air fresheners 10,10' are used
by the consumer by simply pressing it against a smooth glass or
similar surface at the desired location. One appropriate location
is the lower left corner of an automotive windshield. A glass surface
in a refrigerator or a glass-like surface in a refrigerator is also
appropriate. The static cling sheets 20, 20' will cling tightly
to a smooth clean glass surface even in freezing or hot temperatures.
Air fresheners 10, 10' will remain in place for a period of weeks
or months and can be easily removed by peeling it away from the
windshield with a finger or thumbnail. Because no adhesives are
used on the cling face, no adhesive residue is left on the windshield
or other glass surface. Air fresheners 10, 10' can be applied to
any window, mirror, shower stall door, or other glass-like surface
where it will stay in place until removed.
[0040] The static cling properties of vinyls and polyvinyl chloride
films of the class usable in this invention are not defeated by
high humidity or moisture. A non-obtrusive, easily installed, non-messy
and easily removed air freshener is thereby provided.
[0041] Referring now to FIGS. 8-12 wherein the showings are for
the purposes of illustrating a third embodiment of the invention
and not for the purposes of limiting same, FIG. 8 shows an air freshener
110 in accordance with the invention. A rear view or side 112 of
the air freshener 110 is seen in FIG. 8. The rear side 112 is the
side that can be seen from the inside of, for example, an automobile
when the air freshener 110 is applied to the inside surface of the
windshield of an automobile. The rear side 112 comprises a selectively
removable clear cover 130. The clear cover 130 can be a clear acetate
cover provided to protect a fragrance member 128 prior to installation.
[0042] The elements used to construct the air freshener 110 are
seen in FIGS. 9-12. A static cling polymer layer 120 is provided
for mounting to a substantially planar surface and is the front
most element of the air freshener 110 (when in the installed position).
A protective backing or cover 122 can be provided to protect the
static cling polymer layer 120 from contaminants until installation
is desired and/or between installations. The protective cover 122
can be an acetate cover for protecting the, for example, static
cling properties of the static cling polymer layer 120. The static
cling polymer layer 120 can be substantially rectangular and include
a width or first planar dimension 120 w and a height or second planar
dimension 120 h. Along with a footprint 120A substantially defined
as the product of the width dimension 120 w and the height dimension
120 h (120 w.times.120 h). The static cling polymer layer 120 can
be a uniformly thin layer, i.e., 60 mils thick, and is selected
to have static cling properties on its front or first face 120f.
Certain substances, such as certain KALENETM.RTM. POLYMERS manufactured
by United Polymer Technologies are known to cling to surfaces without
the need of an adhesive and can be used for polymer layer 120. The
polymer layer 120 can be transparent or translucent, thereby allowing
a graphic sheet to be visible therethrough.
[0043] barrier, display or graphic sheet layer 124 is provided
with an adhesive on its front or first face 124f (the face facing
a back face 120b of the static cling polymer layer 120), a width
or first dimension 124 w and a height or second dimension 124 h.
The width dimension 124 w and height dimension 124 h of the barrier
sheet 124 can be identical to the width 120 w and height dimension
120 h, respectively, of the static cling polymer layer 120. The
barrier sheet 124 can be substantially rectangular and have a footprint
124A identical to the footprint 120A of the static cling polymer
layer 120. The barrier sheet 124 can be provided with a design on
both faces 124f, 124b, possibly including words and serial numbers,
simulating a parking sticker or club membership decal of the type
frequently seen on automobile windshields.
[0044] The polymer layer 120 and the fragrance member 128 can be
thin polymers of cured liquid butyl rubber. One such suitable substance
is KALENETM.RTM.. Different varieties and compositions of KALENE
products are described in U.S. patent publication 2003/0054311 and
are incorporated in their entirety herein.
[0045] The fragrance member 128 can include a rectangular geometry
having a width or first planar dimension 128 w and a height or second
planar dimension 128 h. The width dimension 128 w and the height
dimension 128 h of the fragrance member 128 can be identical to
the width 124 w and height dimensions 124 h, respectively, of the
graphic sheet 124. The fragrance member 128 can be substantially
rectangular with round or square comers and have a foot print 128A
substantially defined as the product of the width dimension 128
w and the height dimension 128 h (128 w.times.128 h). The fragrance
member 128 can be, for example, about 150 mils thick. The fragrance
member 128 can be transparent or translucent, thereby allowing the
graphic sheet 124 to be visible therethrough. The fragrance member
128 can be a polymer, i.e., a liquid butyl rubber, impregnated with
a scent or fragrance. The fragrance member 128 carries a quantity-of
fragrance (not illustrated). The fragrance can be impregnated in
the liquid butyl rubber prior to curing and can give off a scent
when exposed to air. The fragrance is absorbed into the butyl rubber
of the fragrance member 128 relatively uniformly and will not be
visible. Thus, the appearance of the air freshener 110 from both
the front view 112 and the back view 118 strongly resembles a parking
or membership decal as is frequently seen on the inside of an automobile
windshield or the inside of a locker.
[0046] The thin plastic cover sheet 130 is provided with adhesive
on the front or first face 130f facing the fragrance member 128.
The cover sheet 130 can be provided with a non-adhesive back or
second face 130b for ease of handling and placement to a desired
location. The cover sheet 130 can be rectangular with a width or
first dimension 130 w substantially the same as the width dimension
128 w of the fragrance member 128 and a height dimension 130 h greater
than the height dimension 128 h of the fragrance member 128. The
increased height 130 h of cover sheet 130 provides a tab 131 to
facilitate removal of sheet 130 from fragrance member 128. The cover
sheet 130 can be substantially rectangular and have a foot print
130A substantially defined as the product of the width dimension
130 w and the height dimension 130 h (130 w.times.130 h). The cover
sheet 130 can be a clear acetate material. As can be seen in FIG.
11, the cover sheet 130 lays against the back face 128b of the fragrance
member 128.
[0047] The static cling polymer layer 120, the barrier sheet 124,
and the fragrance member 128 can be flexible. The fragrance member
128 can be fabricated from varying thicknesses of polymer depending
upon the amount of and type of fragrance to be carried in the product
and the desired application. A larger amount of fragrance can be
carried in a thicker member. A thinner fragrance member will be
lighter and can be used with concentrated fragrances which require
relatively less volume.
[0048] The barrier sheet 124 can be fabricated from a plastic film
or fiberboard selected to be impervious to the polymers used and
to the fragrance carried by the fragrance member 128. The graphic
sheet 124 can be printed on both sides 124f, 124b (not illustrated)
to resemble a parking or membership sticker. Paper, cardboard and
fiberboard are easily printed. None of the other layers of the air
freshener 110 needs to be printed. Due to the translucent nature
of the polymer layer 120 and fragrance member 128, the barrier sheet
124 can be viewed therethrough from either side.
[0049] A location for mounting the air freshener 110 is, for example,
near the lower left comer of an automobile windshield. In this position,
the air freshener 110 is exposed to sunlight on warm sunny days.
As described above, the static cling polymer layer 120 and fragrance
member 128 can be transparent or translucent thereby allowing sunlight
therein. Sunlight will penetrate through a transparent automobile
windshield and the polymer layer 120 of the air freshener 110 thereby
illuminating and heating the fragrance member 128. The heated fragrance
member 128 will release fragrance into the automobile interior at
an increased rate when compared to a cold air freshener as most
volatile materials evaporate more quickly when heated. The air freshener
110 can be thus, sunlight activated. On the other hand, in a northern
winter, the air freshener will be "deactivated" when a
car is parked in a cold garage overnight. The air freshener 110
can be subsequently "reactivated" when the driver turns
on the heat, raising the temperature in the car's interior. Thus,
the air freshener 110 is automatically activated, at a variable
rate, as needed only, extending its useful life.
[0050] The fragrance member 128 can include an additive, i.e.,
color, which will change after a set time or duration of exposure
to the air, or after a period of exposure to UV. The change in color,
for example, can be indicative of the expiration of the fragrance
member 128.
[0051] Air freshener 110 can be packaged in an air tight retail
package such as a rib and groove closure plastic bag or a blister
pack (not shown). In this way, the fragrance can be retained in
the fragrance member 128 until the package is opened by the consumer
and the air freshener 110 applied to the desired location. Air freshener
110 is used by the consumer by simply pressing it against a smooth
glass or a substantially planar surface at the desired location.
As discussed above, one appropriate location is the lower left corner
of an automotive windshield. A locker door or other surface in a
locker is also appropriate. The static cling sheet 120 will cling
tightly to a substantially smooth surface even in freezing or hot
temperatures. The static cling properties of KALENE.RTM. of the
class usable in this invention are not defeated by high humidity
or moisture, and are also chemical resistant. Air freshener 110
can remain in place for a period of weeks or months and can be easily
removed by peeling it away from the mounting surface with a finger
or thumbnail. Because no adhesives are used on the cling face, no
adhesive residue is left on the windshield or other mounted surfaces.
Thus, air freshener 110 can be applied to any window, mirror, locker
door, or other substantially flat surface where it will stay in
place until removed. A non-obtrusive, easily installed, non-messy
and easily removed air freshener is thereby provided.
[0052] While considerable emphasis has been placed herein on the
structure of the illustrated embodiments and the structural interrelationships
between component parts of the embodiments, it will be appreciated
that many changes in the embodiments herein illustrated and described
can be made without departing from the principles of the invention.
Accordingly, it is to be distinctly understood that the foregoing
descriptive matter is to be interpreted merely as illustrative of
embodiments and not as a limitation.
