Description
The present invention relates to an air-treating device and, in
particular, to a device for simultaneously storing and using
individual packets of solid air-treating agent.
The sale and manufacture of air treating agents, and in particular
room deodorizers and the like, has expanded substantially in recent
years and a variety of air-treating products or agents recently
have been developed for commercialization. Included among these are
the solid air-treating agents, i.e. solid compositions from which
volatile air-treating materials slowly vaporize when the solid is
exposed to air. Certain of such solid air-treating agents,
described in U.S. Pat. No. 2,929,055, issued to Lanzet, comprise a
solid gel containing volatile air-treating materials.
Solid air-treating agents of this type have many advantages and
have been found to be highly satisfactory in use. In particular,
they do not discharge a liquid phase, as do the aerosol spray
products which may stain garments or furniture and may be
inhaled.
However, one problem with solid air-treating agents is the somewhat
limited manner in which they have been stored and used. For the
solid air-treating agent to be effective it must be exposed to the
atmosphere; thus it cannot be enclosed within a container like that
used with liquid or aerosol spray air-treating agents. Accordingly,
special containers are required to store the solid air-treating
agent while simultaneously exposing enough of it to permit it to
release air-treating vapors as desired. For applications where it
is desirable to move the solid air-treating agent from one room to
another in the home, or to use a small amount of the air treating
agent in a car, boat, or house trailer, no packaging system has as
yet been proposed which will permit simultaneous storage and use of
the agent.
Accordingly, it is an object of the present invention to provide an
air-treating device which utilizes solid air-treating agents and
which is convenient to use and to transport.
Yet another object of the present invention is to provide an
air-treating device, including a solid air-treating agent, for use
in automobiles, house trailers, boats and the like.
Yet another object of the present invention is to provide a
container system for solid air-treating agents in which a supply of
solid air-treating agent can be stored while a portion thereof is
exposed for use.
In accordance with one aspect of the present invention, a portable
air-treating device is provided in which a hollow container, having
upper and lower end portions, is constructed so as to receive and
support a stack of individually sealed packets of solid
air-treating agent. The lowermost packet of the stack is supported
on a support wall at the lower end of the container and the upper
end of the container has a first opening therein through which the
stack of packets is inserted into the container. In addition, the
container includes a wall member which extends between the upper
and lower ends of the container, and which has a free edge spaced
from the lower support wall of the container, thereby to define a
slot in the container adjacent the support wall through which the
lowermost one of the packets in the stack can be removed from the
container. As a result of this construction, individual packets of
solid air-treating agent can be selectively removed from the
container and opened to expose the air-treating agent therein to
the atmosphere. This opened packet can then be returned to the
container through the opening in the upper end thereof for support
on top of the stack and for transport with the container while the
vapors from the air-treating agent there in escape from the
container into the surrounding atmosphere. This opening may, in one
embodiment of the invention, be provided with a closable cover
which will prevent inadvertent discharge of the packets of material
from the container should the container be inverted.
The above, and other objects, features and advantages of this
invention, will be apparent in the following detailed description
of an illustrative embodiment thereof which is to be read in
connection with the accompanying drawings, wherein:
FIG. 1 is a schematic perspective view of an air-treating device,
constructed in accordance with the present invention, mounted on
the dashboard of an automobile;
FIG. 2 is an enlarged plan view of the device illustrated in FIG.
1;
FIG. 3 is a side sectional view taken along line 3--3 of FIG.
2;
FIG. 4 is a sectional plan view taken along line 4--4 of FIG. 3;
and
FIG. 5 is an enlarged perspective view of a packet constructed in
accordance with the present invention and containing solid
air-treating agent.
Referring now to the drawing in detail, and initially to FIG. 1
thereof, it will be seen that air treating device 10, constructed
in accordance with the present invention, is mounted on dashboard
12 of an automobile for use in deodorizing or treating the air in
the automobile. This device, as described more fully hereinafter,
can be utilized in other types of vehicles or enclosures, such as
for example, camping trailers, boats, or the like, and can be used
as a deodorizer for individual rooms in a home.
Air treating device 10, in the illustrative embodiment of the
present invention, is adapted to contain stack 14 (seen most
clearly in FIG. 3) of individual packets 16 containing solid air
treatment agent. By the construction of device 10, individual
packets 16 can be selectively removed from stack 14 and opened to
expose the solid air-treating agent contained therein.
Preferably, air-treating device 10 is constructed as generally
rectangular or square container 18 formed of a plastic material
having upper and lower ends 20, 22 respectively. Upper end 20 of
container 18 forms opening 24 through which the individual packets
16 of solid air-treating agent can be inserted into the container.
Cover 26 is pivotally mounted adjacent opening 24, as for example
on pivot 28 to permit opening and closing opening 24 as desired.
This cover may be provided with a releasable latching mechanism
(not shown) of any convenient known construction so that it is held
securely in its closed position during use of the device, thereby
to prevent stack 14 of packets from being inadvertently discharged
therefrom should container 18 become inverted. In addition, cover
26 has a plurality of apertures 30 formed therein, for reasons more
fully described hereinafter.
Lower end 22 of container 18 includes generally U-shaped bottom
wall 32, illustrated most clearly in FIG. 4, having bight portion
34 and a pair of legs 36 which define opening 37 therebetween at
one side of the container. Legs 36 and bight 34 are adapted to
cooperate with and engage flange 38 formed on the lowermost packet
16 in stack 14 (as described hereinafter) to support that packet
and the stack of packets seated thereon. These packets are of
indentical construction and are placed within the container
individually through opening 24 when cover 26 is raised.
Container 18 also includes front wall member 40 which extends from
upper end 20 of container 18 towards its lower end 22 above opening
37 of U-shaped support wall member 32. However, wall 40 ends at a
location above wall 32 so as to define slot 42 in container 18
between the lower edge 43 of the wall 40 and support wall 32. As a
result of this slotted construction, lowermost packet 16 in stack
14 can be withdrawn from container 18 by grasping the forward edge
of flange 38 of that packet and pulling the packet forward through
the front opening 37 of wall 32 and slot 42. Moreover, lowermost
packet 16 is the only packet withdrawn from the container and, when
it is withdrawn, the next packet falls downwardly under the
influence of gravity onto wall 32, with that packet's flange 38
supported on the bight and let portions of the wall. To facilitate
removal of lowermost packet 16 from the stack within container 18,
notch 46 can be provided in front wall 40 to permit insertion of a
finger into the container and into engagement with flange 38 of the
lowermost packet.
Packets 16, most clearly illustrated in FIG. 5, can be formed in
any convenient manner, and preferably are formed of relatively thin
plastic or metal to define chamber 46 having peripheral wall or
flange 38 formed integrally therewith at its upper edge.
Preferably, packets 16 have a complementary configuration to that
of container 10 so that each of the packets fits closely therein,
as illustrated in FIG. 3. Thus, since container 10 in the
illustrative embodiment of the invention is shown as a generally
square container, packets 16 in the illustrative embodiment are
also formed as squares. Of course, it is to be understood that both
container 10 and packets 16 can be formed in any desired shape,
such as for example round or oval, so long as the principle of
cooperation of the container and the packets as described herein is
maintained.
Returning again to FIG. 5 of the drawing, it is seen that chamber
46 of packet 16 has open upper portion 48 adjacent flange 38 and
contains supply 50 of solid air-treating agent therein. This
air-treating agent may be of the type described in the above
mentioned Lanzet patent, for example. Opening 48 is selectively
covered by foil sheet 52, such as of metal or plastic, which may be
adhered along edges 54 thereof to flange 38 by any convenient
adhesive material. With sheet 52 covering opening 48, solid air
treatment agent 50 in chamber 40 is isolated from the atmosphere
and thus will not release vapors. In addition, chamber 46 is
dimensioned to fit between legs 36 of wall 32 to permit flange 38
of pockets 16 to be engaged and supported by wall 32, as seen in
FIG. 3.
Accordingly, by providing a stack of individual packets 16 within
container 18, a relatively large supply of air-treating agent can
be stored without deterioration and without the escape of volatile
ingredients therein to the atmosphere.
When it is desired to use the solid air-treating agent contained
within the packets, lowermost packet 16 in stack 14 is removed from
container 10 in the manner described above, and sheet 52 is removed
from the container to expose the air-treating material. The packet
is then returned to container 18 through opening 24 so that the
opened packet, with the air-treating material now exposed, is now
on the top of stack 14. In this position, vapors from the solid
air-treating agent can escape through openings 30 in cover 26.
These openings may take the form of a plurality of slots, as
illustrated in FIG. 2 of the drawing, or they may be formed as
circular or oval holes, or the like.
In one embodiment of the invention, container 18, as illustrated in
FIG. 1 of the drawing, can be secured to the dashboard of an
automobile or other vehicle. In this case the container can be
provided with suitable attachment means, for example, magnet 56
secured to rear wall 58 of the container in any convenient manner,
e.g. by an adhesive or by screws, bolts or the like. The magnet
will hold the container on the dashboard or elsewhere in the
vehicle in a location convenient for use. Of course, it is to be
understood that other convenient mounting means such as an adhesive
strip or the like could be provided on container 18 for securing
air-treating device 10 of the present invention to a wall or other
surface.
Accordingly, it is seen that a relatively simple and inexpensive
container is provided for storing and transporting individual
packets of a solid air-treating agent and for selectively exposing
a portion of the stored air-treating agent to the atmosphere for
use. By this construction only a portion of the air-treating agent
is used at one time while the remainder is kept in a sealed
condition for storage.
Although an illustrative embodiment of the present invention has
been described herein with reference to the accompanying drawings,
it is to be understood that the invention is not limited to that
precise embodiment and that various changes and modifications may
be effected therein by one skilled in the art without departing
from the scope or spirit of this invention.
