DECORATIVE ROOM AIR TREATING DEVICE
Abstract
A decorative room air treating device in the shape of a flower
pot or other aesthetically appealing container having a body
portion with circular cross-sections, as for example, one
constructed of a pair of concentric frusto-conical plastic
containers dimensioned to fit closely, but rotatably one within the
other. The top end of the inner container is closed by a transverse
wall from which projects upwardly a plastic simulated horticultural
item, such as a flower. A cake of an air treating substance is
disposed within the inner container and the side walls of the two
containers are so orificed that in one rotational position relative
to each other, none of the orifices of the two containers fall into
registry, but in a second rotational position, they are disposed in
registry. In positions intermediate the two extremes, the orifices
of the two containers may be disposed in various degrees of
registry.

__________________________________________________________________________
A principal problem with all of such devices is that, despite
efforts on the part of inventors, designers and manufacturers to
provide the devices with an aesthetic appearance, they still look
like cans, jars or other objects which are usually quite
incompatible with the customary decor of a living room, den,
bedroom or bathroom. Even the Gould patent device with its
fragrance releasing simulated flower would seem to be quite
artificial in its appearance.
While undoutedly skilled designers could, if engaged especially for
this purpose, produce works-of-art embodiments of such devices,
there are certain practical problems which have inhibited such
efforts. In the first place, the device should be adjustable in
order that one may vary the rate of evaporation of the deodorizing
gel, depending upon the extent of the need therefor in the room or
space in which the device is placed. Should there be little need
therefor, the evaporation rate should be minimized in order to
prolong the useful life of the device; but where the room may have
been subject to heavy smoking or other offensive order producing
activities, it may be desirable to increase substantially, for at
least a brief period, the evaporation rate of the gel and the
dispensation of the vapor into the room.
Secondly, the device should be adapted to fit in with the decor of
any of the rooms in which it is to be placed, e.g. bathroom,
bedroom, den, living room, dining room, kitchen or family room.
Whatever design is adopted, therefore, must have a rather universal
adaptability to many different room decors.
Thirdly, the container for the gel must be able to be fabricated
and sold so cheaply that when the useful life of the gel has ended,
the householder may afford to throw the container away.
Alternatively, it might be desirable to provide a container in
which a new cake of gel could conveniently be inserted to replace
the one which has evaporated.
In addition, despite the desirability of extreme economy in
manufacture, a device of the type herein contemplated must be
carefully and specially designed to be easily operated by the
average householder and to avoid leakage of the gel and sticking of
rotatable parts.
These objectives have not hitherto been attained by any prior room
deodorizing device.
SUMMARY OF THE INVENTION
The present invention provides a room air treating device which may
in the form of an attractive flower pot from which protrudes a
plastic flower, such as a daisy, with or without additional
greenery, or other aesthetically appealing container. The flower
pot may be constructed as a double-walled vessel with an inner wall
portion or vessel which fits closely but rotatably within the
outer-walled vessel. The inner-walled vessel serves as a container
for a cake of deodorizer gel and is orificed at a plurality of
locations about its frusto-conical or cylindrical side. The
outer-walled vessel is so orificed that in one angular position of
the inner-walled vessel relative to the outer walls, non of its
orifices falls into registry with any of the orifices in the
inner-walled vessel, but in other positions, such registry occurs
in varying degrees up to complete registry of all orifices of both
the inner and outer vessels.
The top of the inner-walled vessel may be closed by a removable
transverse wall from which may extend one or more plant or greenery
stems. In one embodiment of the invention, the transverse wall may
have an overhung knob onto which a receptable of the lower end of a
flower stem may be snapped. In another embodiment of the invention,
the transverse wall may have molded into it at least one downwardly
extending receptacle into which may be stuck the stem of a plastic
plant or other simulated greenery stem. In still another
embodiment, the first two greenery arrangements may be combined.
All components of the deodorizer container may be readily molded of
a plastic material such as polystyrene or high-impact polyethylene,
at a minimum of expense. Alternatively, the deodorizer may be in
the form of any other type of vessel having circular cross-sections
and formed to provide an aesthetically attractive appearance.
Thus, the deodorizing substance is contained in a decorative
simulated potted plant or other attractive container which may be
placed appealingly anywhere in the house, and deodorization may be
effected by rotating the outer wall of the flower pot vessel or
other form of container to a position relative to its inner wall
wherein the orifices of both vessels are placed in the desired
degree of registry.
When the deodorizer cake is completely evaporated, it may be
replaced by simply removing the transverse top wall on the
inner-walled vessel and dropping a new cake into the latter.
In another embodiment of the invention, the inner walls of the
inner container may be provided with ribs, veins or other
projections to hold the cake away from most of the inner wall
surface, thereby to improve the air circulation about the cake and
hence to permit better evaporation and dispensing of the cake vapor
through the registering orifices in the container walls.
To facilitate the rapid molding of both the inner and outer
containers with their respective orifices the upper edges of the
orifices are preferrably sharply bevelled inwardly, thereby
permitting the containers to be more easily ejected from the molds
without the necessity of providing expensive camming ejecting
equipment.
While it is desirable on the one hand that the inner and outer
containers rotatably fit closely enough to prevent leakage of the
gel through the orifices in the outer container when those of the
inner container are not disposed in register with the orifices of
the outer container, it is important that the two containers not
fit so closely together that relative rotation of them is made
difficult. To this end the inner walls of the outer container
between the orifices may be at least slightly recessed thereby
minimizing the contacting surfaces between the inner and outer
containers through which surfaces friction may develop.
Desirably some guide means should be provided to enable the user to
known when he or she has rotated the inner container relative to
the outer container either to provide full orifice registry or to
fully close the outer orifices. For this purpose an interrupted
annular bead may be provided to extend slightly radially outwardly
from the rim of the outer container. The upper end of the inner
container extends beyond the rim of the outer container and
preferrably is provided with an annular overhanging flange which
extends radially beyond the rim and bead of the outer container
thereby providing an annular recess rototatably receive said rim
and its bead. However, stop means may be provided within the
annular recess so that rotation of the containers is permitted only
to the extent of the interruptions of the bead. These interruptions
should be of such arcuate distance as to just slightly exceed the
width of the outer container window orifices and so disposed as to
allow rotation of the inner container from a first position wherein
none of the orifices of the inner container is in registry with any
of the orifices of the outer container, to a second rotational
position wherein all of the orifices of the inner container are in
registry with those of the outer container.
Provision should also be made for secure but removable seating of
the upper transverse wall which closes the upper end of the inner
container. This may be accomplished by providing slight radially
inwardly extending projections past which the edge of the
transverse wall may be snapped and held until pried out from the
seating.
Lastly, in order to enable the inner and outer containers to be
automatically assembled by machines, projections may be provided in
the bottom wall of the outer container to be caught by the portion
of the machine tool which is rotated to cause the interruptions in
the annular bead on the rim of the outer container to receive the
stop means within the annular recess formed by the overhanging
flange of the inner container rim.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-3 of the drawings, the decorative room
treating device 10 may be comprised of an outer vessel 12,
preferably conical in configuration as a flower pot, and inner
vessel 14 of similar configuration, but dimensioned to fit closely
but rotatably within the outer vessel 12. The top of the inner
vessel is closed by a transverse wall 16. In the embodiment shown,
this wall 16 is provided with a plurality of wedges 18 on its
underside which wedges with the periphery of the wall 16 seat
within the inner surface 20 of the inner vessel 14. The latter
includes an upwardly extending angular conical segment 22, an
annular horizontal rim 24 and a downwardly extending annular wall
26. The transverse wall 16 itself may be provided with a centrally
disposed raised overhung knob 30 and a plurality of downwardly
extending receptacles 32.
Each vessel 12, 14 is orificed at a plurality of locations 12a, 14a
respectively in its conical side wall 12b and 14b, respectively.
Orifices 12a are so disposed relative to orifices 14a, however,
that in one angular rotational position of vessel 14 relative to
the outer vessel 12, none of the orifices 14a fall into registry
with orifices 12a, but in another position, all of them are brought
into registry.
The underside 28 of the inner vessel 14 is preferably provided at
its center with a bearing 34 which may be seated in a mating recess
36 in the bottom wall 38 of the outer vessel 12. This bearing 34
not only serves as a means about which the inner vessel 14 may be
rotated within the outer vessel 12, but it also supports the inner
vessel 14 sufficiently upwardly to prevent the conical wall 14b of
the inner vessel 14 from being jammed against the inner surface 20
of the conical wall 12b of the outer vessel 12.
The device is completed by first inserting within the vessel 14 and
before the wall 16 is placed inside the wall 14b, a cake 36 of an
evaporable deodorizing gel, as for example, one of the type
disclosed in U.S. Pat. No. 2,927,055 issued Mar. 1, 1960 to Airkem,
Inc., as assignee of Monroe Lanzet, although many other types of
such gels obviously could be utilized. The transverse wall 16 is
then placed inside the conical wall surface 20 and seated therein
where it is supported by the wedges 18. A simulated plastic flower
38 is then mounted on the knob 30 by forcing the gripping
receptacle 40 at the base of the flower stem 42 onto the overhung
knob 30. Stems 44 of additional greenery 46 may then be inserted
into the receptacles 32.
All components of the device, with the exception of the gel cake,
may be molded of plastic materials. The vessels 12, 14 and
transverse wall 16 may be made of polystyrene or high-impact
polyethylene, while the flower 38 and greenery 46 may be molded of
polyethylene.
In use, the two vessels 12, 14, with the gel cake 36 inserted into
the bottom of the inner vessel 14 closed by the wall 16, and with
their respective orifices 12a, 14a entirely out of registry, may be
shipped and sold in a carton also containing a packet with the
flower and greenery. After removing the vessels from the carton and
the flower and greenery from the packet and mounting them on the
wall 16, the householder needs only to rotate the room 24 of the
inner vessel 14, until the latter's orifices 14a fall into registry
with the orifice 12a of the outer vessel 12, to the degree
necessary to provide the desired rate of evaporation of the gel
cake 36 into the room in which the deodorizer 10 is placed. When
the room shall have been sufficiently deodorized, the rim 24 may be
again rotated to place the orifice 12a, 14a out of registry,
thereby blocking further evaporation of the gel cake 36 and
preserving its useful life. Alternatively, the orifices 12a, 14a
may be placed only partly in registry to provide a lesser rate of
evaporization and hence deodorization. When the gel cake 36 shall
have been dully evaporated, it may be replaced simply by removing
the transverse wall 16 and dropping a new cake into the bottom of
the vessel 14.
The preferred embodiment of the invention which is illustrated in
FIGS. 4-7 includes certain features which are important from
production and operation standpoints. Thus, it will be observed
that upper edges 48, 50 of the orifices 12a' and 14a' are beveled
at 52, 54 inwardly from the outsides of their respective walls 12b'
and 14b' so that the upper edges 48, 50 are almost razor thin. This
enables the vessels 12', 14' better to be ejected from their
respective molds without the necessity of expensive cam ejecting
mechanisms.
In addition, in order to minimize the friction which develops
between the abutting walls 12b', 14b' when vessel 14' is inserted
into vessel 12', the inside surface of the wall 12b' of vessel 12'
may be recessed between orifices 12a'. These recesses also effect a
saving of the plastic material required to mold vessel 12'.
It will also be noted that an interrupted arcuate bead 56 is
provided to extend radially outwardly from the upper rim 58 of the
outer vessel 12'. Through the interruptions, the bead 56 is
actually broken up into a series of discrete arcuate segments 56a,
56b, 56c, etc. which are separated by spaces 58a, 58b, 58c, etc.
The annular horizontal rim 24' and downwardly extending annular
wall 26' are so dimensioned and the latter is so spaced from the
wall 14b' as to rotatably receive the thus beaded rim 58 of the
outer vessel 12'. However, in order to limit the rotation of the
inner vessel 14' within the outer vessel 12' a position where the
orifices 12a', 14a' of the vessels 12', 14' are in registry and a
position where they are not so in registry, a series of stop
members 60 may be provided within the annular recess 62 define by
the downwardly extending wall 26' and the upper rim of the wall
14b'. These stop members 60 will block relative rotation of the
vessels 12', 14' at the points where the ends of the arcuate
segments 56a, 56b, 56c, etc. strike the stop members 60. By
providing such stop members, not only will the housewife or other
user be guided in setting the orifices 12a', 14a' into either
registering or non-registering positions, but the devices may be
machine assembled, since the two vessels may be moved together
co-axially and then twisted into a non-registering position of the
orifices. For this purpose gripping means 64 may be provided on the
underside of the outer vessel 12' so that a machine tool head 66
may be moved in against such means 64 to effect the desired
twisting to where all orifices 12a', 14a' are placed entirely out
of registry.
In the FIGS. 4-7 embodiment, the transverse wall 16' which closes
the top of the inner vessel 14' is snapped over a plurality of
small radially inwardly extending projections 68 and held in an
annular seat formed by the intersection of the horizontally
extending flange 24' with the inner wall of the upwardly extending
rim portion of the vertical flange 26'. With this construction the
lid 16' may be securely seated to close the top of the inner
vessel, yet it may be pried out in order to enable the user to
replace the gel cake after it has evaporated. Also in this
embodiment, a single plastic flower stem 69 is inserted in a
downwardly projecting receptacle 70, this flower stem having
extending laterally from the point where the stem protrudes from
the lid 16', plastic supports 72 from which extend upwardly a
plurality of flower greenery leaves or stalks 74.
In order to improve the air circulation around the cake and hence
to increase evaporation of the cake vapors into the area
surrounding the FIGS. 4-7 deodorizer, the inside of the wall 17b'
may be provided with radially inwardly projecting ribs of
projections 76 which support the cake 36' away from the inner
surface of the wall 14b'.
Thus, the foregoing embodiments of the present invention not only
provide very useful and functional deodorizing devices, but devices
which, because they so resemble a flower pot with a blooming flower
or other decorative device, are aesthetically attractive enough to
fit with the decor of most rooms of the average house. Further,
since the entire containing units may not be fabricated of plastic,
they may be made and sold at relatively low prices. In addition,
since such devices need not be thrown away when their evaporative
gel cakes have been dissipated, but each may be renewed with the
insertion of a new gel cake, the present invention will not only
appeal to the economic housewife, but also to all persons who are
interested in promoting ecology by decreasing the number of
throw-away items which they use and must dispose of.
