Description
This invention relates generally to waste disposable equipment, and
more particularly concerns a collar assembly for supporting a
plurality of nested trash liners.
In providing a collar support for trash liners, it is important
that the liner bags be securely attached to the support assembly in
an opened mouth fashion in order that the liners, themselves, do
not interfere with the placement of trash into the receptacle. At
the same time, however, it is also important that the method of
attaching the liner bags to the collar be such as to ensure the
easy removal of the liners when they become filled and to permit
the convenient insertion of a replacement liner.
Various trash liner support arrangements are available which, when
properly used, are acceptable for use in collecting trash.
Nevertheless, each of these support arrangements suffers from one
drawback or another which makes it inconvenient and, in general,
inefficient to use when the frequent replacement of liners is
required. For example, most support arrangements are designed to
carry only a single liner at a time. Because of this, it is
necessary to stop and attach a new replacement liner each time the
liner bag becomes filled. Not only does this require the person
changing the liner to constantly carry a supply of replacement
liners with him, but, depending upon the complexity of the support
assembly, it often requires an appreciable amount of time to effect
the change.
Likewise, most prior art arrangements require the person changing
the liners to carry closure means with him for sealing the open end
of the liner once it is removed from the support. If such closure
means are not used, there is a high degree of likelihood that some
of the collected trash will spill out of the liner resulting in a
condition which is both inefficient and unsanitary.
It is, therefore, the aim of the present invention to eliminate
such disadvantage found in the prior art apparatus, and to provide
trash disposal apparatus which facilitates the sanitary collection
of disposable trash with a minimum of maintenance effort.
Accordingly, it is an object of this invention to provide an
independent support assembly for maintaining a plurality of nested
liner bags within a trash receptacle.
A related object is to provide a support assembly of the foregoing
type which facilitates the removal of the inner most liner bag from
the trash receptacle when it becomes filled to capacity and
provides a replacement liner which is already properly positioned
within the receptacle.
In addition, it is a further object of this invention to provide a
support assembly which is particularly adapted for use with liner
bags which comprise a closure device as an integral part of the
liner.
Still other objects and advantages of the invention will become
apparent upon reading the following detailed description and upon
reference to the drawings, in which:
FIG. 1 is an illustrative view showing the unpackaging and
placement of a support collar constructed in accordance with the
present invention on a trash receptacle.

While the invention will be described in connection with a
preferred embodiment, it will be understood that it is not intended
to limit the invention to that embodiment. To the contrary, it is
intended to cover all alternatives, modifications and equivalents
as may be included within the spirit and scope of the invention as
defined in the appended claims. For example, while the illustrative
embodiment described herein relates to a support collar shaped for
use with a cross-sectionally rectangular trash receptacle (FIG. 8),
it is not intended to limit the invention to such a configuration.
To the contrary, the apparatus of the present invention is equally
suited for use with receptacles having circular cross-sections
(FIG. 9), oval cross-sections (FIG. 10), or any other
configurations and it is herein intended to encompass all such
alternatives.
In accordance with the present invention Trash Disposal Apparatus
is provided which, when used in conjunction with conventional trash
receptacles, facilitates the sanitary collection of disposable
trash. To this end, the apparatus includes a support collar 20
adapted to engage with and be carried by the upper rim of the trash
receptacle 30 for simultaneously supporting a plurality of nested
trash liner bags 36 a-c within the confines of the receptacle.
Referring to the drawings, there is shown in FIG. 1 an illustrative
embodiment of the support collar assembly 20 constructed in
accordance with the present invention. The collar comprises a pair
of spaced-apart side wall members 22 and 23 joined at their upper
ends by a top member 25 and shaped to form a square, U-shaped
channel 27 suitable for engaging the upper rim 29 of a
complimentarily shaped trash receptacle 30. As shown, this
receptacle is of the geometrically square variety often found in
homes and offices. As previously indicated, however, it is not
intended to limit the invention to any particular size or shape.
Rather, it is herein contemplated that the support collars 20 will
be constructed to conform to the particular size and shape of the
receptacle for which it is designed. To this end, there are certain
general considerations which must be kept in mind, i.e., the
channel width of the collar must be sufficiently wide to fit over
the rim of the receptacle, the depth of the U-shaped channel must
be sufficient to give stability to the collar arrangement when it
is placed on the trash receptacle 30, and the external height of
the support collar must be sufficient to enable the individual
attachment of a desired number of liner bags. In addition, it is
desirable that the support collar 20 be sufficiently rigid to
ensure ease in handling when inserting or removing the collar
structure 20 from the trash receptacle 30. Although a wide variety
of materials could be used for obtaining the desired
characteristics, it is presently contemplated that the support
collar 20 will be constructed from either a heavy weight cardboard
or a plastic material such as polystyrene.
To support the individual trash liner bags, attachment means are
provided on the outer perimeter of the support collar 20 for
independently engaging the opened ends of a pluality of nested
liner bags 36 a-c. In the illustrated embodiment, these attachment
means are shown in the form of a plurality of notches 32 located at
graduated intervals on each corner 34 of the support collar 20. As
will be appreciated by those skilled in the art, this form of
attachment means is particularly suited for use with liner bags 36
a-c having a drawstring 38 integrally connected at their opened
end. Absent a liner bag arrangement which includes a drawstring
suitable for engagement in such notches, alternate attachment means
are contemplated in the form of hook projections or double stick
tape which also would be positioned at graduated intervals in order
to facilitate the removal of each of the independently attached
liner bags.
In use, it is contemplated that the support collar 20 will come
prepackaged, such as in a cardboard container 40, with a plurality
(approximately 7-10) of nested liner bags independently attached
with their drawstrings inserted in the respective corner of the
collar structure. For packaging purposes, the respective liner bags
36 a-c will be collectively folded and held within the confines of
the collar structure by a paper strip or band 42. By maintaining
the folded liner bags in this way, the unpackaging and handling of
the support assembly prior to placement on the trash receptacle 30
is also facilitated. Once the support structure 20 is properly
aligned with the upper rim of the trash receptacle 30, the band 42
can be removed and the support collar 20 can then be lowered into
place on the receptacle. Although the bags will generally tend to
drop into the receptacle once the packaging band 42 is removed,
proper positioning of the liner bags 36 within the receptacle 30
can be ensured by placing one's hand or other object through the
center of the support collar 20 and collectively depressing the
nested liner bags 36 to the bottom of the receptacle 30. Once
positioned, it is not necessary to disturb the support collar 20
until all of the individually attached liner bags 36 have been
removed.
Pursuant to the invention, individual liner bags are independently
removed as they become filled. Since openings 39 are provided to
expose the drawstring 38 at each corner of the liner bags 36,
removal of a filled liner bag is accomplished by simply grasping
the exposed portions of the drawstring 38 and removing it from the
respective corner notches 32 in the support collar. In this way,
the liner bag is completely freed from the support collar 20 (FIG.
7) and can be removed simply by lifting it out of the trash
receptacle 30. Provided that the filled liner 36 is not the last
liner attached to the support collar, removal of the inner most
liner does not require any additional effort since, in keeping with
the design of the present invention, a replacement liner is already
properly positioned within the receptacle. When, however, the last
liner 36 c is removed from the support collar, a new supply of
liner bags can be inserted in place by simply removing the empty
collar and replacing it with a new one having a fresh supply of
liner bags. Since it is contemplated that the support collar 20
will be made of a disposable material, the empty collar, itself,
can simply be disposed of once the replacement collar is properly
positioned on the trash receptacle.
Further, it should be noted that any of the large number of
commercially available liner bags can be used in carrying out the
present invention. In general, however, it is contemplated that
disposable liners constructed of plastic ranging in thickness
between 2.0 and 4.0 mills will be used.
Thus, it is apparent from the foregoing that there has been
provided, in accordance with the invention, trash disposal
apparatus which fully satisfies the objects, aims, and advantages
set forth above.
