Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. Ser. No.
11/454,392, filed Jun. 15, 2006, the contents of which is hereby
incorporated herein in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to a container, and
more particularly, but not by way of limitation, to an improved
expandable receptacle that allows quick and easy removable of the
contents of the receptacle.
[0004] 2. Brief Description of Related Art
[0005] Convention trash receptacles are configured with a specific
capacity. A common practice is to line the trash receptacle with a
plastic liner to facilitate disposal of the refuse collected in the
receptacle. In many instances, it is desirable to use large
capacity liners, e.g., 55 to 60 gallons. Such large capacity liners
have the advantage of being more cost effective than smaller
capacity liners and do not require changing as often. However,
problems are encountered with the use of large capacity liners.
First, individuals are more susceptible to injury when pulling the
liner from the receptacle due to the increased weight of the larger
liner. Second, the receptacle used to support a large capacity
liner must be of sufficient size to do so. Consequently, it may be
inconvenient to store a receptacle of such size.
[0006] To this end, a need exists for an improved expandable
receptacle that allows quick and easy removal of the contents of
the receptacle. It is to such an apparatus that the present
invention is directed.

DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring now to the drawings, and more particularly to
FIGS. 1-3, an expandable receptacle 10 constructed in accordance
with the present invention is shown. The expanded receptacle 10 is
illustrated as functioning as a support for a plastic liner 11
(FIGS. 2 and 3). However, it should be appreciated that the use of
the expandable receptacle 10 of the present invention is not
limited to being used as a liner support. The expandable receptacle
10 may be used for storing or transporting a variety of objects.
The expandable receptacle 10 has an outer tubular member 12, an
inner tubular member 14, a stand 16, and a lid 18. The outer
tubular member 12 has inner surface 20, an outer surface 22, an
open top 24, and an open bottom 26. A pair of handles 28 are
provided on the outer surface to facilitate moving the outer
tubular member 12. Similarly, the inner tubular member 14 has an
inner surface 30, an outer surface 32, an open top 34, and open
bottom 36. The outer surface 32 of the inner tubular member 14 may
also be provided with a pair of handles 38.
[0016] The inner tubular member 14 is dimensioned to fit in the
outer tubular member 12 in a telescopic relationship with the outer
surface 32 of the inner tubular member 14 contacting the inner
surface 20 of the outer tubular member 12. The outer tubular member
12 and the inner tubular member 14 are preferably manufactured from
a durable, plastic material, such as polyethylene, so as to permit
the inner tubular member 14 to slide relative to the outer tubular
member 12 and thereby permit the inner tubular member 14 to be
moved along a longitudinal axis 40 of the inner tubular member 14
and the outer tubular member 12 from a collapsed position (FIG. 2)
to an expanded position (FIG. 3). Furthermore, the inner tubular
member 14 is constructed to have sufficient flexibility so that a
pressure exerted on the inner surface 30 of the inner tubular
member 14 causes the outer surface 32 of the inner tubular member
14 to frictionally engage the inner surface 20 of the outer tubular
member 12 to support the inner tubular member 14 in the expanded
position, in a manner to be described below.
[0017] The outer tubular member 12 and the inner tubular member 14
are shown to have a circular shape. However, it should be
appreciated that the outer tubular member 12 and the inner tubular
member 14 may be constructed of various and geometric shapes. In
addition, the outer tubular member 12 and the inner tubular member
14 may be made from various materials, such as metal, plastic, and
wood.
[0018] The outer tubular member 12 and the inner tubular member 14
cooperate to define a content receiving compartment 42 having an
open top 44 and an open bottom 46, whereby contents of the content
receiving compartment 42 are removable therefrom by lifting the
inner tubular member 14 and the outer tubular member 12 upward and
away from the contents. As mentioned above, the expandable
receptacle 10 is illustrated in FIGS. 2 and 3 as functioning as a
support for the liner 11, which has a closed lower end 48 and an
open upper end 50. The liner 11 is positioned in the content
receiving compartment 42 with the open upper end 50 extended over
the top 34 of the inner tubular member 14. While the capacity of
the liner 11 may vary, the expandable receptacle 10 effectively
supports large capacity liners, such as those liners having a
capacity of approximately 60 gallons, by way of example.
[0019] The stand 16 is adapted to support the liner 11, the outer
tubular member 12, and the inner tubular member 14. The stand 16
includes a base 52 and a sidewall 54 dimensioned to receive and
support the bottom 26 of the outer tubular member 12. The stand 16
and the outer tubular member 12 may be provided with a latching
mechanism (not shown) that releaseably connects the outer tubular
member 12 to the stand 16. Such latching mechanism may include a
foot pedal (also not shown) to facilitate release of the outer
tubular member 12 from the stand 16 when it is desired to remove
the contents of the content receiving compartment 42 therefrom. The
stand 16 preferably includes a plurality of wheels or rollers 56 to
permit the expandable receptacle 10 and its contents to be moved
from one location to another, as desired.
[0020] In use, refuse or other materials are disposed in the liner
11 with the inner tubular member 14 and the outer tubular member 12
in the collapsed position (FIG. 2). As the content receiving
compartment 42 becomes filled, the inner tubular member 14 is moved
upward to increase the capacity of the content receiving
compartment 42 by lifting the inner tubular member 14 with the
handles 38 to a desired position. The inner tubular member 14 is
supported in the expanded position (FIG. 3) by the outward pressure
exerted on the inner tubular member 14 by the contents of the liner
11. More specifically, the contents of the content receiving
compartment 42 cause the outer surface 32 of the inner tubular
member 14 to frictionally engage the inner surface 20 of the outer
tubular member 12 and thereby support the inner tubular member 14
in the expanded position. The inner tubular member 14 is moved
upward incrementally until the capacity of the liner 11 is reached.
Prior to the liner 11 being filled to capacity, the lid 18 may be
used to cover the liner 11.
[0021] With the liner 11 filled to its capacity, the liner 11 is
tied or otherwise sealed. The filled liner 11 is removed from the
expandable receptacle 10 (FIG. 4) by lifting the inner tubular
member 14 and the outer tubular member 12 upward and away from the
liner 11. If the outer tubular member 12 is connected to the stand
16, the outer tubular member 12 is first disconnected from the
stand 16. Next, the inner tubular member 14 is lifted up and over
the liner 11, followed by the outer tubular member 12.
Alternatively, the outer tubular member 12 may be lifted so as to
cause the top 24 of the outer tubular member 12 to contact the
handles 38 of the inner tubular member 14 whereby the outer tubular
member 12 and the inner tubular member 14 are lifted over the liner
11 as a unit. With the outer tubular member 12 and the inner
tubular member 14 separated from the liner 11, the filled liner 11
may be transported via the stand 16 to a desired location for
disposal, without requiring the liner 11 being lifted out of the
expandable receptacle 10.
[0022] Referring now to FIGS. 5 and 6, another embodiment of an
expandable receptacle 10a is illustrated. The expandable receptacle
10a has an outer tubular member 12a, an inner tubular member 14a, a
stand 16a, and a lid 18a. The inner tubular member 14a, the stand
16a, and the lid 18a are similar in construction to the inner
tubular member 14, the stand 16, and the lid 18 described above.
The outer tubular member 12a has an inner wall 60 and a outer wall
62 joined at a lower end thereof. The inner wall 60 and the outer
wall 62 are spaced to define a slot 64 having an open top 66. The
slot 64 is dimensioned to receive the inner tubular member 14a so
that the inner tubular member 14a is movable from a collapsed
position (FIG. 5) to an expanded position. The inner tubular member
14a is supported in the expanded position in a manner similar to
that described above in reference to the expandable receptacle 10.
That is, the contents of the content receiving compartment exerts a
pressure on the inner wall 60 of the outer tubular member 12a,
which in turn squeezes the inner tubular member 14a between the
inner wall 60 and the outer wall 62.
[0023] FIG. 7 shows the outer tubular member 12a and the inner
tubular member 14a provided with a stop mechanism 68 which
functions to prevent the inner tubular member 14a from separating
from the outer tubular member 12a. The stop mechanism 68 includes a
catch member 70 formed on the inner tubular member 14a near the
bottom thereof and a catch member 72 formed on the outer tubular
member 12a near the top thereof. It should be appreciated that the
stop mechanism 68 may also be employed in the expandable receptacle
10.
[0024] FIG. 8 illustrates the expandable receptacle 10a provided
with an interlocking mechanism 74 as an additional or alternative
means for supporting the inner tubular member 14a in the expanded
position. The outer tubular member 12a may include a series of
recesses 76 adapted to receive a ridge 78 formed on the inner
tubular member 14a. It will be appreciated that the interlocking
mechanism 74 may take a variety of other forms. For example, the
ridge 78 may be formed on the outer tubular member 12a (the outer
wall, the inner wall, or both) and the recesses 76 formed on the
inner tubular member 14a so as to correspond with the ridge of the
outer tubular member 12a. The interlocking mechanism 74 may be
incorporated into the expandable receptacle 10.
[0025] From the above description it is clear that the present
invention is well adapted to carry out the objects and to attain
the advantages mentioned herein as well as those inherent in the
invention. While presently preferred embodiments of the invention
have been described for purposes of this disclosure, it will be
understood that numerous changes may be made which will readily
suggest themselves to those skilled in the art and which are
accomplished within the spirit of the invention disclosed and as
defined in the appended claims.
