INCORPORATION BY REFERENCE
[0002] U.S. patent application Ser. No. 09/951,112, filed Sep.
10, 2001, and U.S. Provisional Patent Application No. 60/231,256,
filed Sep. 8, 2000, are hereby incorporated by reference herein
in their entireties and made a part of this specification.
BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] The present invention relates to air fresheners and supply
units therefor.
[0005] 2. Description of the Related Art and Summary of Invention
[0006] Air fresheners are frequently used in home and business
to control odors in bathrooms, kitchens, and other enclosed spaces.
Generally, commercial dispensers for air fresheners can operate
passively through ventilation and diffusion, or actively through
electrical heating elements or mechanical fan assemblies. Because
air freshener dispensers function by releasing a scent through evaporation
or atomization, such dispensers work most effectively when placed
in the open on a counter, table, or wall. They are nevertheless
often hidden from view due to their odor eliminating purpose, where
they are both less effective and more difficult to replace.
[0007] Numerous methods have been developed to improve air freshener
dispensers for the home and business. Electrically powered and wall
mounted dispensers are common. U.S. Pat. No. 4,808,347 to Dawn discloses
an air freshener with a battery powered fan for deodorization of
automobiles. Similarly, U.S. Pat. No. 4,743,406 to Steiner et al.
describes a self-contained dispenser which uses replaceable cartridges
of air freshener, and applies a battery powered fan to actively
vent air past the cartridge. Air freshener dispensers have even
been applied to common cassette tapes, as disclosed in U.S. Pat.
No. 4,905,112 to Rhodes, in part to deodorize automobiles in a discrete
and clever fashion. Unfortunately, none of these solutions provide
an ideal solution for the home, office or storefront, as many require
electric power, often necessarily with replacement of batteries
as well as air freshener. These solutions usually do not suit themselves
to placement in visible areas where such air freshener dispensers
would be most effective.
[0008] Hand lotion, on the other hand, is commonly provided in
home and business environments to moisturize, smooth, and improve
the condition of skin. It is often available in disposable consumer
pour or pump dispensers, or sometimes in wall units for commercial
application. Consumer dispensers are commonly placed on tables,
in kitchens, and in bathrooms, and do not have the less desirable
appearance and connotation of an air freshener dispenser.
[0009] Applicant is one of the named inventors for U.S. Pat. No.
5,799,826, in which a dual dispenser was disclosed. That dual dispenser
was disclosed as being used with soap and air freshener. This combination
of soap and air freshener in a single dispenser was highly innovative
for soap. When used with standard soap (which is rinsed off), rather
than a sanitizer soap (which is not rinsed off), the dispenser is
desirably placed reasonably near a source of water to allow washing
off the soap after use. As standard soaps are by far the most popular,
the placement of standard soap dispenser is limited, as it is impractical
in non-washroom settings such as the coffee table, office desk,
or the automobile.
[0010] Accordingly, a preferred embodiment is a dispenser that
can be placed virtually anywhere in the home or office. Another
aspect of a preferred embodiment is a dispenser for both air freshener
and a liquid, such as hand lotion or soap, that avoids the difficulties
of prior individual and combined dispensers while providing advantageous
improvements in both structure and function.
[0011] Most retail, or consumer-oriented, air fresheners operate
on an "always on" basis. That is, once the air freshener
is initially activated, it dispenses fragrance until its supply
is exhausted. Because air freshening is typically only necessary
when a person is in the same general area as the air freshener dispenser,
the "always on" dispensers may result in a majority of
the fragrance being dispensed when it is not necessary or desired.
[0012] Further, the dispensed fragrance, along with most other
odors, are only noticeable to a person for a short time after the
smell is encountered. After this initial period, the person becomes
accustomed to the fragrance and it no longer produces the desired
sensory response. More user oriented consumer air fresheners are
available, such as spray-type products, for example. However, the
necessary mechanisms to propel the air freshener often make spray-type
dispensers relatively expensive and difficult to recycle.
[0013] Accordingly, a preferred dispenser dispenses only a small
amount of fragrance, if any, until the dispenser is user-actuated.
Advantageously, such an arrangement avoids desensitization, thus
increasing the perceived effectiveness of the air freshener. In
addition, such a dispenser avoids unnecessary dispensing of fragrance,
thereby increasing the useful life of the fragrance. Moreover, such
a dispenser provides both a pourable compound, such as hand lotion,
and air freshener in a single product, which is less costly than
purchasing hand lotion and air freshener separately. In addition,
less packaging materials are utilized in comparison to separate
products, thereby reducing the amount of material disposed of or
needing to be recycled at the end of the product life.
[0014] A preferred embodiment is an assembly including a dispenser.
The dispenser includes a container and an actuator, which defines
an actuation surface. A pourable compound is held within the container
and is dispensible from the container upon manual manipulation of
the actuation surface. A base defines a substantially flat mounting
surface and an interior surface sized and shaped to receive and
retain the dispenser. The base also includes a location sized and
shaped to receive a supply of air freshener wherein the supply of
air freshener is received by the location.
[0015] A preferred embodiment is an air freshener delivery assembly.
The assembly includes a bottle, a hood and a supply of air freshener.
The hood includes a wall cooperating with at least a portion of
the bottle to form a cavity. The supply of air freshener is positioned
within the hood. In addition. the hood is movable with respect to
the bottle from a first position, wherein the hood and the bottle
cooperate to define a first generally enclosed volume, to a second
position wherein the hood defines a second enclosed volume smaller
than the first enclosed volume, thereby dispensing air freshener
from the supply of air freshener.
[0016] A preferred embodiment is an assembly including a first
engagement portion defining a cavity and an actuator defining an
actuation surface. A pourable compound is positioned within the
first engagement portion, wherein the compound is dispensible from
the first engagement portion upon manual manipulation of the actuation
surface. The assembly also includes a second engagement portion,
which defines an interior surface sized and shaped to receive and
retain the first engagement portion. The second engagement portion
also defines a location sized and shaped to receive a supply of
air freshener, which is positioned at the location.
[0017] A preferred embodiment is an assembly including a first
engagement portion defining a cavity and an actuator defining an
actuation surface. A supply of hand lotion is placed within the
first engagement portion, wherein the supply of hand lotion is dispensible
from the first engagement portion upon manual manipulation of the
actuation surface. A second engagement portion defines a location
sized and shaped to receive a supply of air freshener and a supply
of air freshener is positioned at the location.
[0018] A preferred embodiment is a dispenser assembly including
a first portion at least partially defining a first enclosure for
receiving a supply of hand lotion. A second portion at least partially
defines a second enclosure for receiving a supply of air freshener.
The second portion has at least one opening and is movable relative
to the first portion to a dispensing position for urging the air
freshener in a direction from within the second enclosure toward
the opening. A pump assembly communicates with the supply of hand
lotion and defines an outlet positioned outside of both the first
and second enclosures. The hand lotion is urged in a direction from
within the first enclosure toward the outlet when the pump assembly
is actuated. The second portion is movable to the dispensing position
independent of the actuation of the pump assembly.
[0019] A preferred embodiment is a dispenser assembly including
a first portion at least partially defining a first enclosure for
receiving a supply of hand lotion. A second portion at least partially
defines a second enclosure for receiving a supply of air freshener.
The second portion has at least one opening. A pump assembly communicates
with the supply of hand lotion and defines an outlet positioned
outside of both the first and second enclosures. The hand lotion
is urged in a direction from within the first enclosure toward the
outlet when the pump assembly is actuated. A means is provided for
dispensing the air freshener from within the second enclosure through
the opening without an external supply of power.
[0020] A preferred embodiment is a dispensing base for use with
a liquid dispenser and an air freshener enclosure. The base includes
a substantially flat mounting surface and an interior surface sized
and shaped to receive the liquid dispenser. The base also includes
a location sized and shaped to receive the air freshener enclosure.
The base defines at least one hole through which air freshener from
the air freshener enclosure can be dispersed.
[0021] Another aspect of a preferred embodiment is a combination
air freshener and hand lotion dispenser that permits direct user
control of the strength and quantity of scent released in relation
to dispensing of hand lotion.
[0022] Yet another aspect of a preferred embodiment is a combination
air freshener and hand lotion dispenser in which the supplies of
hand lotion and/or air freshener are refillable or replaceable independently
or as a unit.
[0023] Still another aspect of a preferred embodiment is a combination
air freshener and hand lotion dispenser where the dispensing of
hand lotion, for example through a pump, is used to indirectly power
the release of air freshener through a mechanically powered or passive
ventilation system.
[0024] Finally, yet still another aspect of a preferred embodiment
is a combination air freshener and hand lotion dispenser where the
release of air freshener and dispensing of hand lotion are independently
controllable.
[0025] Hand lotion is often dispensed in pour, squeeze, or pump
bottles for home and business environments, where those bottles
are usually disposable. As is known by those of skill in the art,
hand lotion may include various combinations of moisturizers, oils
and emollients, and may include nutritive elements such as Vitamin
A, Vitamin E or Aloe Vera. While hand lotion may be scented, its
primary function is placement directly on the hands to improve the
skin's condition. Hand lotion generally does not have to be washed
off the hands after use, as with standard soap. It does not function
efficiently as an air freshener, and would be ineffective and messy
if used as such. Hand lotion is an emulsion of primarily water and
various oils, with lecithin typically being at least one of the
emulsifying agents. If skin renewal properties are desired, the
lotion may contain 2-8% of an alpha or beta hydroxy ingredient,
to promote exfoliation.
[0026] Air freshener means any entity designed for the purpose
of masking odors, or freshening, cleaning or deodorizing the air.
The main ingredient of most air fresheners is a fragrance. Air fresheners
previously had a chemical composition consisting of 10-25% fragrance,
although substantially more or less fragrance, between 1-99% would
be present depending on the strength of the resulting scent, the
placement and purpose of the air freshener and the type of carrier
the fragrance is placed within. Carriers for fragrance may include,
for example, an odorless mineral spirit to dilute and aid in evaporating
the fragrance, polymer gel, or a semisolid wax, which evaporates
the fragrance at ambient temperature or upon heating. A porous surface
frequently is used to prevent leakage but allow diffusion of fragrance
into the surrounding environment, including, for example a polyester
matrix in which the fragrance and carrier can be suspended. In 1997,
the EPA established Volatile Organic Compound (VOC) content limits
for air fresheners. Since fragrances very often contain VOC, these
limits must be considered in the process of air freshener design.
However, VOC content limits do not apply to air fresheners whose
VOC constituents consist of 100% fragrance. This latter kind of
air freshener can contain any desired amount of fragrance (0-100%).
[0027] Preferred embodiments realize an advantageous combination
air freshener dispenser and hand lotion dispenser. A preferred embodiment
includes a method for combining a hand lotion dispenser and air
freshener dispenser to allow control of air freshener diffusion
based on dispensing of hand lotion, or, alternatively, passively
diffusing air freshener through controlled continuous ventilation.
Both methods may be combined in the same apparatus. This can be
accomplished through a number of physical embodiments, the preferred
of which are described below.
[0028] A preferred embodiment includes an apparatus for combining
a hand lotion dispenser and air freshener dispenser to allow subtle
continuous dispensing of air freshener passively through the use
of one or more adjustable vents. Thus, within one embodiment of
a dispenser, at least two vent units are included where one of the
vents is moveable with respect to the other. The vent units may
have one or more openings in each which allow communication of fragrance
from the air freshener enclosure to the outside environment. For
example, the vent units may include surfaces which can be separated
on user operation creating an opening for communication of fragrance
to the outside environment. By manually adjusting the moveable vent
unit, a user can regulate the rate of diffusion of fragrance into
the surrounding environment and hence control the strength of scent
from the air freshener dispenser.
[0029] Alternatively, at least one vent unit is included in the
unit, where at least one vent unit is moveable to create an opening
between the surface of the vent unit and the base of the dispenser
for ventilation of air freshener. For example, the moveable vent
may be automatically adjusted on user pumping of the hand lotion
dispenser to dispense hand lotion in additional embodiments of the
present invention. A preferred dispenser is particularly convenient
for private use, as it can be placed anywhere in the home or office
and is fully adjustable with respect to dispensing of hand lotion
and release of air freshener.
[0030] A preferred embodiment also includes an apparatus for combining
a hand lotion dispenser and air freshener dispenser in such a manner
as to allow dispensing of air freshener actively through a number
of optionally non-electrified mechanisms initiated by a user's pump
action when dispensing hand lotion. Such an apparatus allows for
but removes the need for batteries or electrification of the unit,
while providing a controlled, active ability to diffuse fragrance.
In one preferred embodiment, depression of the hand lotion pump
handle provides a measured quantity of hand lotion as would a standard
pump mechanism, but also affects a release of air freshener through
compression of a mechanical energy transferring device.
[0031] Preferably, within the vent unit, or alternatively in the
vent units or base unit, a resilient sponge and, optionally, a flat
plate can be placed beneath the air freshener enclosure, where the
plate can be attached to the pump tube such that depression of the
pump handle depresses both the pump tube and the flat plate. Depression
of the flat plate compresses the resilient sponge, allowing the
release of fragrance currently held within the sponge to the outside
environment through the opening or openings in or between the vent
units. When the pump handle is released, the flat plate releases
the sponge, and the sponge expands and draws in more fragrance from
the air freshener enclosure. A spring may optionally be used to
complement the resilient sponge, such that the spring is placed
around the pump tube in a manner that the spring is compressed when
the pump handle is depressed, and releases its stored energy when
the pump handle is released, thus providing greater expansion and
fragrance input into the uncompressed sponge. Alternatively, the
flat plate may be omitted by the use of an air freshener enclosure
having a surface suitable to adequately compress the sponge.
[0032] A similar result can be achieved by use of a mechanical
fan assembly placed above or below the air freshener enclosure within
the vent unit or units. When the pump handle is depressed, the downward
force is transferred to the pump tube and the mechanical fan assembly,
which translates the downward force into a rotational force acting
on the fan. The fan then spins for a brief, adjustable time during
which fragrance is drawn from the air freshener enclosure, and between
or out of the vent unit or vent units, and or base unit, into the
outside environment.
[0033] In addition, it is contemplated to substitute a manual pump
arrangement for the above-described mechanical fan assembly. In
such an arrangement, the vent unit surrounds the upper portion of
the base unit and creates a cavity to house the air freshener enclosure.
The vent unit is capable of sliding relative to the base unit, so
that when the pump handle is depressed, the cavity volume is simultaneously
reduced. This forces the air contained therein to be evacuated,
and fragrance drawn from the air freshener enclosure to the outside
environment, in a manner similar to the mechanical fan assembly.
With this arrangement, the vent unit may be depressed individually,
thereby releasing fragrance without dispensing hand lotion.
[0034] Alternatively, the vent unit may be placed below, and surround
a lower portion of the base unit creating a cavity to house the
air freshener enclosure below the base unit. In this arrangement,
depression of the pump handle would dispense hand lotion, while
depression of the base unit itself would force the evacuation of
air from the cavity, and draw fragrance from the air freshener enclosure
to the outside environment. Such an apparatus allows for active
air freshening without the need for batteries, and at the same time
allows for adjustment in the strength of fragrance released. As
mentioned previously, the active and passive methods may be combined
to allow a combination of continuous and user-initiated fragrance
release at varying strengths depending on manual adjustment of the
dispenser and environmental need.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0048] With reference to FIG. 1, one embodiment of a combination
hand lotion and air freshener dispenser 10 employing passive diffusion
is detailed in an exploded view. The combination dispenser 10 comprises
a base unit 53, with a pump handle 11 which defines a spout 11a
for dispensing of hand lotion as well as a surface 11b for depression
regulating pump action for dispensing of hand lotion. The pump handle
11 is connected to the inner spout tube 12, which extends from the
pump handle 11 to the hand lotion enclosure 50. The inner spout
tube reaches through the hand lotion enclosure opening 51 and then
extends into the supply of hand lotion 52 inside the hand lotion
enclosure 50.
[0049] The hand lotion enclosure 50 is defined by at least one
distinct wall that creates a separate compartment in which hand
lotion 52 may sit. Such a compartment may have any cup or bottle
shape convenient to hold the hand lotion within the many possible
shapes of the present invention. Such a compartment may be enclosed
within or form the base unit 53 of the dispenser.
[0050] The inner spout tube 12, below the pump handle 11, may also
be attached to an optional spout seal 13 and optional outer spout
tube 14. When included, the spout seal at least partially surrounds
the inner spout tube 12, and seals the top of the outer spout tube
14. The outer spout tube 14 surrounds the inner spout tube 12 from
the spout seal 13 to some point before or at the end of the inner
spout tube 12 in the hand lotion enclosure 50. As well known in
the art, the pump mechanism of 11, 12, 13 and 14 creates a pressurized
pump region on pressing of the pump handle 11b by depressing both
the inner spout tube 12 which extends all the way to the pump handle
11 and the outer spout tube 14 which is sealed at the spout seal
13. In this manner hand lotion is dispensed at the pump handle spout
11a. More generally, any suitable pump mechanism for liquid may
be provided.
[0051] Between the pump handle 11 and the hand lotion enclosure
50 and base 53 are an upper vent unit 20 and optional lower vent
unit 30. Preferably, the upper vent unit consists of at least one
surface at least partially surrounding the inner spout tube 12 and
optional outer spout tube 14, where the optional spout seal 13 attaches
to the upper vent unit 20 via a standard screw top, rubberized seal,
or similar method known in the art. One or more ventilation holes
21 may be placed in the upper vent unit 20. Similarly, the lower
vent unit 30 may contain one or a number of ventilation holes 31,
where the optional lower vent unit 30 consists of at least one surface
at least partially surrounding the inner and optional outer spout
tubes 12 and 14.
[0052] The upper ventilation unit 20 is preferably capable of rotation
with respect to the lower ventilation unit 30, as indicated by the
arrow 22 in FIG. 1. The upper ventilation unit 22 is moveable between
a fully closed position, where there is substantially no overlap
between the vents 21 of the upper ventilation unit 20 and the vents
31 of the lower ventilation unit 30, and a fully open position,
wherein there is substantially complete overlap of the vents 21
and 31. Additionally, the upper ventilation unit 20 may be positioned
at substantially any desired position between the fully open and
fully closed position. In this manner, the rate of passive evaporation
of air freshener from the air freshener enclosure 40 may be adjusted.
Alternatively, the upper vent unit 20 and lower vent unit 30 may
be separable to create a ventilation opening between them.
[0053] The air freshener enclosure 40 at least partially surrounds
the inner 12 and optional outer 14 spout tubes, and may lie between
the optional lower vent unit 30 and hand lotion enclosure 50 or
base 53 such that the upper 20 or optional lower vent unit 30 or
base 53 may serve to completely enshroud the air freshener enclosure
40. The air freshener enclosure 40 may be removable 41, for example,
by lifting the optional lower 30 and upper 20 vent units in order
to expose the air freshener enclosure. In one of many variations
of this embodiment, the air freshener enclosure 40 may lie between
the upper vent unit 20 and optional lower vent unit 30, or between
the upper vent unit 20 and hand lotion enclosure 50 or base 53.
[0054] The air freshener enclosure 40 may consist of fragrance
suspended in a carrier, may expose a polyester matrix on one or
more surfaces to allow evaporation of fragrance, and or may itself
have one or a number of openings for release of fragrance. The air
freshener enclosure 40 is preferably small enough to fit within
the vent units 20 or 30, and base unit 53, and conform to one of
the many shapes possible for the present invention.
[0055] A second embodiment of a dispenser 10 is illustrated in
FIG. 2. A standard pump apparatus consisting of a pump handle 11
with pump spout 11a and a surface 11b for compression to initiate
pump action is connected to an inner spout tube 12. The optional
spout seal 13 similarly at least partially surrounds the inner spout
tube 12 and seals the end of the optional outer spout tube 14.
[0056] The upper vent unit 20 and optional lower vent unit 30 may
be similar to the first embodiment, except the vent unit or units
20 and 30 serve to enclose the air freshener enclosure 40, an optional
circular plate defining a surface 60, and a resilient sponge 70.
The three components 40, 60 and 70 may be placed in any order between
the upper and lower vent units 20 and 30, but the placement of the
air freshener enclosure 40 above the plate surface 60, with the
plate surface 60 itself above the sponge 70, is preferred. Alternatively,
the optional plate surface 60 may be omitted, and substituted with
an air freshener enclosure 40 equipped with an appropriate surface
to compress the resilient sponge 70. Thus, when such an arrangement
is used, the air freshener enclosure 40 effectively functions as
both an air freshening device and as the plate surface 60.
[0057] The air freshener enclosure 40 contains fragrance usually
suspended in a carrier, and may be optionally removable. The air
freshener enclosure 40 at least partially surrounds the inner 12
and optional outer 14 spout tubes and, in at least one preferred
embodiment, does not move when the pump handle 11 is depressed 11b.
It is small enough to fit within the vent unit or units 20 and or
30, and the base unit 53, and otherwise conforms to one of the many
shapes possible for the current invention. The plate surface 60
is attached to the optional outer 14 and or inner 12 spout tubes
such that when the pump handle 11 is depressed, the plate surface
60 is depressed 60b. The plate surface 60 at least partially surrounds
the optional outer 14 and inner 12 spout tubes and when depressed
60b compresses the sponge 70b.
[0058] The resilient sponge 70 at least partially surrounds the
optional outer 14 and inner 12 spout tube, and is sufficiently porous
to allow air to leave the sponge when compressed and fill the sponge
when decompressed. When the pump handle 11 is depressed 11b, the
plate surface 60 compresses the sponge, releasing the air and air
freshener stored within it through or between the ventilation unit
or units 20 and 30 and/or the base unit 53, and out into the external
environment 5.
[0059] When the pump handle 11 is released, the plate 60 lifts,
the sponge 70 decompresses, and fragrance from the air freshener
enclosure 40 is drawn into the sponge 70 from the resulting pump
action. This embodiment may also combine the sponge 70 and air freshener
enclosure 40 in the base unit 53, or release fragrance by drawing
apart the upper and lower ventilation units 20 and 30 upon pump
action 11b. Alternatively, fragrance may be released by drawing
apart the upper ventilation unit 20 from the base unit 53 with or
without the use of ventilation holes 21. Upon pump action 11b, hand
lotion 52 is dispensed through the inner spout tube 12 and out the
pump handle spout 11a.
[0060] Optionally, the hand lotion pump handle 11 may be rotated
to turn off dispensing hand lotion 11a by use of an optional valve
15 (illustrated schematically in FIG. 2) at the joint of the pump
handle 11 and the inner spout tube 12, as is known in the art. Thus,
the pump action of the handle 11b can be used to indirectly power
air freshener dispersion without dispensing hand lotion. Optionally
and similarly, the hand lotion pump handle 11 may be rotated to
prevent transfer of mechanical energy from pump action 11b to the
mechanical energy transfer device to prevent active dispersion of
air freshener while dispensing hand lotion.
[0061] In FIGS. 3 and 4, another embodiment of a preferred dispenser
10 is shown. In this embodiment, the lower vent unit 30 may also
contain a mechanical fan assembly 55, which comprises: a spring
32, a fan 33, and a helical gear 34 (FIG. 5). The helical gear 34
may be attached to, or defined by the inner spout tube 12 and mates
with helical threading of the fan 33 to translate linear motion
of the inner spout tube 12 into rotational motion of the fan 33.
As the fan 33 turns 33a, an air freshener enclosure 40 evaporates
more aggressively due to the action of the fan 33 and disperses
through or between the optional lower 30 and/or upper 20 vent units,
or between the upper vent unit 20 and base unit 53, into the surrounding
environment 5.
[0062] Upon compression of the pump handle 11, in addition to turning
the fan 33, the inner spout tube 12 and optional outer spout tube
14 are moved in a manner where the optional outer spout tube 14,
or alternatively the inner spout tube 12, compresses the spring
32. Upon release of the pump handle 11, the spring 32 assists in
restoring the dispenser 10 to its original position and prepares
it for further use. By adjusting the helical gear 34, manually adjusting
22 the upper vent, or placing a stronger or weaker air freshener
enclosure 40 in the invention, the rate of evaporation and strength
of fragrance dispersed into the external environment 5 can be optionally
adjusted.
[0063] FIG. 5 illustrates an additional embodiment of a preferred
dispenser in which air freshener is actively dispensed upon user-initiated
dispensing of hand lotion. In addition, the dispenser of FIG. 5
is capable of actively dispensing air freshener independently of
dispensing hand lotion. This arrangement advantageously permits
both simultaneous dispensing of air freshener and hand lotion for
convenience, while allowing the same dispenser to be used for active
dispensing of air freshener alone, at such times when odor control
is desired while the use of hand lotion is not necessary or desired.
[0064] In the embodiment of FIG. 5, the upper vent, or hood, 20
partially covers the base unit 53 so as to create a cavity, or enclosure,
37 between them for placement of an air freshener assembly 60. The
hood 20 includes an upwardly extending neck portion 19, which is
contacted by the pump assembly 11 to move the hood 20 downward upon
actuation of the pump assembly 11. Desirably, the base unit 53 includes
a recessed upper portion 61 generally corresponding with the coverage
of the hood 20. This allows the outer surface of the hood 20 to
be substantially flush with the outer surface of the base unit 53
and provides for an aesthetically pleasing outward appearance.
[0065] Preferably, the hood 20 is engaged with the air freshener
assembly 60 to substantially seal the cavity 37, while still allowing
relative motion between the hood 20 and air freshener assembly 60.
A spring 62 biases the hood 20 into an uppermost, or non-dispensing
position. The illustrated spring 62 is a helical coil spring, however,
other suitable types of springs may also be used. Preferably, the
spring rate of the spring 62 is selected such that the hood 20 is
quickly returned to the uppermost position when the pump handle
11 is released, yet allows the hood 20 to be moved into the dispensing
position without requiring excessive downward pressure.
[0066] The air freshener assembly 60 is supported on the upper
surface of the base unit 53. The hand lotion enclosure opening 51
extends upward through a central opening 64 in the air freshener
assembly 60. Preferably, the hand lotion enclosure opening 51 is
defined by a substantially cylindrical neck 54 and communicates
with the interior space of the base unit 53. The neck 54 preferably
includes external threads 56 that mate with internal threads 75
of a threaded cap 76 of the pump 11.
[0067] Preferably, the air freshener assembly 60 includes a plurality
of tabs 64 extending downward over an upper portion of the base
unit 53. The inner surfaces of each tab 64 defines an abutment surface
which contacts the base unit 53 and inhibits the air freshener assembly
60 from rotating relative to the base unit 53. Preferably, four
tabs 64 are provided with two on each side spaced from the central
axis of the dispenser. Advantageously, this feature allows a threaded
pump assembly to be assembled to the base unit 53 without causing
rotation of the air freshener assembly 60.
[0068] With reference to FIGS. 6-9, an alternative embodiment of
a dispenser 10 is shown in partial cross-section. The dispenser
10 of FIG. 6 is similar to the dispenser of FIG. 5, with the exception
that the neck portion 19 of the hood 20 has been omitted. However,
the dispenser 10 of FIGS. 6-9 may optionally include a neck portion
19, if desired, while still performing substantially as described.
The air freshener assembly 60 comprises a tray 66 which supports
two carrier pads 68. The carrier pads 68 are preferably made of
a polyester matrix and carry the supply of air freshener. However,
other suitable, preferably porous, carrier materials may be used.
A pair of projections, or support posts, 70 extend upward from the
upper surface of the tray 66. The support posts 70 pass through
an aperture 72 in the carrier pads 68 to position the pads 68 with
respect to the tray 66 and prevent the pads 68 from moving during
shipment or use of the dispenser 10. However, the support posts
70 permit the carrier pads 68 to be deliberately removed so that
the pads 68 may be replaced. Preferably, the support posts 70 have
a generally "X" shaped cross-section (FIG. 5) for ease
of manufacturing, however, other suitable configurations may also
be utilized.
[0069] A central flange portion 74 of the tray 66 is held between
the upper surface of the base assembly 53 and a threaded cap 76
of the pump 11 thereby securing the tray 66 to the base assembly
53. The tray 66 defines a lip 78 about its periphery. The lip 78
is slideably engaged with the inner surface of the upper vent unit
20 to substantially seal the cavity 37, as described above. Preferably,
the lip 78 is curved to allow easier movement of the hood, or upper
vent, 20.
[0070] With reference to FIG. 7, the dispenser of FIG. 5 is illustrated
in a dual dispensing mode. When the pump handle 11 is pressed downward
to dispense hand lotion, the upper vent 20 is simultaneously moved
downward. As a result, the volume of the cavity 37 is decreased,
thereby expelling a portion of air within cavity 37, which contains
fragrance, through the vents 21. Preferably, the downward travel
of the upper vent unit 20 is approximately 3/4 inches, however,
other suitable travel distances may also be used. Thus, in the dual
dispensing mode of FIG. 7, fragrance is actively dispensed simultaneously
with the dispensing of hand lotion. Additionally, the fragrance
is dispensed by the same downward pressure that dispenses the hand
lotion.
[0071] Additionally, when the pump handle 11 and vent unit 20 are
moved downward, the spring 62 is compressed. Upon release of the
pump handle 11, the stored energy within the spring 62 is released
thereby moving the vent unit 20 relative to the base unit 53 so
as to increase the volume of the cavity 37. A fresh supply of air
is drawn into the cavity 37 through the vents 21. The fresh air
drawn into the cavity 37 increases the rate of evaporation of the
air freshener supply within the carrier pads 68, thus increasing
the fragrance within the cavity 37 and preparing the dispenser 10
for further use.
[0072] With reference to FIG. 8, the dispenser of FIG. 5 is illustrated
in an air freshener dispensing mode. In this mode, a downward pressure
is applied to the upper vent unit 20 thereby moving the vent unit
20 in a downward direction while the pump handle 11 remains in an
uppermost, or non-dispensing position. Air freshener is dispensed
from the cavity 37 in a manner substantially as described above,
without dispensing hand lotion.
[0073] FIG. 9 is a dispenser substantially identical to the dispenser
of FIG. 5, except that the support posts 70 originate from the base
unit 53, rather than being connected to the tray 66. The support
posts 70 pass through corresponding apertures 80 in the tray 66.
In addition, a retention head 82 is provided on the upper end of
each support post 70. Each retention head 82 defines a retention
surface 84 for retaining the carrier pad 68 onto the support post
70.
[0074] The retention heads 82 are preferably sized slightly larger
than the apertures 72 of the carrier pads 68 such that the carrier
pads 68 can be assembled onto the support posts 70 over the retention
heads 82, while the retention surfaces 84 provide resistance against
the carrier pads 68 being removed from the support posts 70. Advantageously,
with such an arrangement, accidental removal of the carrier pads
68 by young children is inhibited.
[0075] FIG. 10 is an additional embodiment of an active air freshener
dispenser 10. In the illustrated embodiment, a vent unit 20 is constructed
to slidingly receive the base unit 53 of the dispenser 10. Preferably,
an air freshener enclosure 40, as described above, is placed within
a cavity 37 defined between the vent unit 20 and the base unit 53.
A spring 32 is operably positioned between the vent unit 20 and
the base unit 53 to bias the base unit 53 into an upward position.
The pump handle 11 may be depressed to dispense hand lotion in a
known manner. The base unit 53 may be pressed downward to actively
dispense air freshener in a manner substantially as described above.
The spring 32 advantageously assist the base unit 53 in moving to
an upward position, thus preparing the dispenser 10 for further
use.
[0076] Advantageously, the vent unit 20 may be configured to receive
a standard, commercially available hand lotion dispenser. Thus,
the standard dispenser would serve as the base unit 53. Such an
arrangement would allow convenient replacement of the base unit
53 with a variety of products that are commercially available in
a standard pump dispenser, such as hand soap or hand sanitizer,
for example.
[0077] The vent unit 20 may be configured in a variety of shapes
and sizes. For example, FIGS. 11 and 12 illustrate front and side
views, respectively, of a vent unit 20 having a substantially trapezoidal
shape in both the front and side views. In addition, the upper end
of the vent unit 20 comprises a curvilinear shape for aesthetic
appeal.
[0078] FIGS. 13 and 14 illustrate front and side views, respectively,
of an alternative embodiment of a vent unit 20 for receiving a standard
pump dispenser. The vent unit 20 of FIGS. 13 and 14 comprise a generally
rounded shape in both the front and side views. In addition, the
vent unit 20 includes a generally triangular central cutout in both
the front and side of its upper end. Preferably, the triangular
cutout is also provided in the back and hidden side.
[0079] FIG. 15 illustrates a passive embodiment of a vent unit
20 for receiving a standard pump dispenser. The standard dispenser
is received in the vent unit 20 in a fixed manner. That is, the
cavity 37 defined therebetween is not variable in volume. However,
an adjuster ring 86 is positioned over the vents 21 provided in
the vent unit 20 to allow adjustment of the rate of air freshener
dispensing. The adjuster ring 86 is rotatably engaged on the vent
unit 20 and provided with a plurality of vents 88, which preferably
correspond in size, shape and placement with the vents 21. The adjuster
ring 86 can be moved from a fully closed position, in which the
vents 21 are fully closed, to a fully open position, wherein the
vents 21 and vents 88 are substantially aligned.
[0080] Preferred embodiments may take any shape practical for dispensing
of hand lotion, soap or other personal care products. Thus, it is
foreseen that the present invention could take the shape of any
generally available consumer pump unit, a wall or table mounted
unit, a portable unit for purse or automobile, or permanent unit
with replaceable enclosures for air freshener and hand lotion. Such
permanent units can be, for example, ceramic, glass, stone or plastic
home design units with varying themes, pictures, or sculpted in
any shape, or an ordinary commercial unit.
[0081] A preferred embodiment uses air freshener and hand lotion.
Any commercially available hand lotion may be used. One preferred
air freshener enclosure may contain a fragrance manufactured by
Premier Specialties, Inc. of Middlesex, N.J. and may be fragrance
#PSI-01842. If necessary, fragrance can be mixed with a volatile
carrier such as an odorless hydrocarbon solvent (e.g., ISOPAR G
manufactured by the Exxon Corp). As discussed above, however, in
the United States limits are placed on Volatile Organic Compound
(VOC) content in consumer products, including air fresheners. Therefore,
an air freshener used in the United States must be designed and
formulated to obey VOC limits.
[0082] Although this invention has been described in terms of certain
preferred embodiments, other embodiments that are apparent to those
of ordinary skill in the art are also within the scope of this invention.
For example, the dispensing of other liquids, the electrification
of the current invention, application to a vertical wall or horizontal
countertop mountable unit, and use of other dispensing methods besides
a pump are considered part of this invention. Accordingly, the scope
of the invention is intended to be defined by the claims that follow.
