Elastic loop for securing a bag to a trashcan
Abstract
The elastic loop for securing a bag to a trashcan is an elastic
cord formed as an endless loop. The loop may be formed in
one-piece, or may be a linear cord with its two ends coupled
together to form a continuous loop by, e.g., a coupler crimped
about opposing ends of the cord. The elastic cord is constructed of
a plurality of elastic strands wrapped tightly in a pliable tubular
cover. The continuous loop has a circumference less than the
circumference of a trashcan for which it is adapted but can be
stretched to fit tightly around the trashcan and thereby secure a
trash bag to the trashcan.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to devices for securing a
disposable bag to a container and, more particularly, to an elastic
loop used to secure the open end of a disposable trash bag over the
rim of a trashcan, thereby preventing the trash bag from sliding
down into the trashcan.
[0003] 2. Description of the Related Art
[0004] Generally, when a trashcan is used as a refuse receptacle at
an indoor or outdoor function, the trashcan is lined with a
disposable plastic trash bag. Typically, the bag is inserted into
the trashcan with the open end of the bag folded over the rim of
the can. A common problem with this arrangement, however, is that
the bag often slips down into the trashcan. Often, as refuse is
added to the bag, the open end of the bag is pulled into the
trashcan and then buried under later added refuse. In such
circumstances, emptying the trashcan is more difficult and time
consuming. Instead of simply transporting the bag and its contents
to a larger container, the trashcan must also be transported to the
larger container and, once at the larger container, the trashcan
must be inverted to empty it contents. Moreover, if the indoor or
outdoor function is still proceeding, then the trashcan must be
returned to its prior location.
[0005] Various devices have been used for securing a disposable bag
to a trashcan. For example, some devices are used for securing a
disposable trash bag to a trashcan by clamping the upper portion of
the bag against the outer aspect of the can. U.S. Pat. No.
4,630,752, issued Dec. 23, 1986 to R. A. DeMars, teaches a rigid
hoop attached in a rotatable, hinged relationship to one handle of
a trashcan, and U.S. Pat. No. 5,556,063, issued Sep. 17, 1996 to B.
S. Boyd, teaches a trash bag retaining band adapted for a specific
trashcan. However, neither of these devices can be used to quickly
and simply secure a bag to a trashcan with a minimal amount of
effort, nor is a single embodiment of either device capable of
being used with trashcans of different sizes. The rigid hoop of the
'762 patent fits the specific trashcan to which it is attached and
requires adequate space and effort to be rotated into position.
Likewise, although the retaining band of the '063 patent is
sufficiently expandable to slide over and around the rim of a
corresponding trashcan, disposing the band in such a position
requires physical effort and, further, a single embodiment of the
retaining band cannot be used with more than one size trashcan.
[0006] Consequently, a need exists for a device for securing a
disposable trash bag to a trashcan in such a manner that the bag
will not slip down into the can as refuse is deposited therein, and
that can accomplish this task with minimal effort on a variety of
trashcan sizes. Such a device would ensure the easy removal of
refuse from a trashcan and would avoid both the necessity of
transporting a trashcan to a large refuse container and the
necessity of inverting the trashcan to empty its contents.
[0007] In addition to the patents discussed above, various devices
have been developed for securing a bag to a trashcan via a hooks or
brackets, including U.S. Pat. No. 4,735,340, issued Apr. 5, 1988 to
J. H. Preston (rim-mounted bag handle brackets); U.S. Pat. No.
4,763,808, issued Aug. 16, 1988 to J. R. Guhl et al. (wire
rim-mounted bag handle brackets); U.S. Pat. No. 4,938,380, issued
Jul. 3, 1990 to M. T. Donahoe (container with external rim-mounted
bag handle retainers); U.S. Pat. No. 4,957,252, issued Sep. 18,
1990 to V. W. Watkins (support frame for bags with handles); U.S.
Pat. No. 5,100,087, issued Mar. 31, 1992 to S. B. Ashby (container
with external side-mounted fastening devices); and U.S. Pat. No.
5,915,584, issued Jun. 29, 1999 to J. M. Sposit (rim-mounted
internal hooks for bag handles). The notable drawback of these
devices is that each is adapted to support a plastic bag with
handles, such as those used by grocery stores. Thus, these devices
are not suited for securing a conventional trash bag, without
handles, to a trashcan.
[0008] Devices which do not attach a trash bag to a trash can, but
merely hold the bag in an open position are described in U.S. Pat.
No. 3,614,041, issued to E. L. Koger (elevated rim with spring
loaded fastener); U.S. Pat. No. 4,738,478, issued Apr. 19, 1988 to
P. W. Bean, Jr. (hand-held rim for supporting a flexible bag); U.S.
Pat. No. 5,163,278, issued Nov. 17, 1992 to J. E. Martenhoff
(funnel with fastening hooks for lawn bag); U.S. Pat. No.
5,217,271, issued Jun. 8, 1993 to C. A. Moe (portable bag holder);
U.S. Pat. No. 5,913,496, issued Jun. 22, 1999 to V. G. Valdez
(hand-held bag frame); U.S. Pat. No. 6,488,242, issued Dec. 3, 2002
to F. A. Barriere (wall mounted bag rim); and U.S. Pat. Publication
No. 2003/0019981, published Jan. 30, 2003 (hand-held bag frame with
clips). While useful in holding the bag open, none of the devices
can be used with a conventional trashcan.
[0009] Other devices having some features in common with the
present invention but which do not teach or suggest an elastic loop
for securing a trash bag to a trash can are shown in U.S. Pat. No.
5,806,416, issued Sep. 15, 1998 to J. A. Cerniglia (yard and trash
compactor that uses cords with hooks) and U.S. Pat. No. 6,047,708,
issued Apr. 11, 2000 to Panel et al. (a thin resilient band used in
a hair bun kit). However, while the Cerniglia patent teaches a
device incorporating cords having multiple strands, it does not
teach a permanent closed loop; and while the Panel patent teaches
an elastic loop formed by crimping the ends of an elastic strand,
it does not teach a multi-stranded elastic loop.
[0010] Thus, none of the above inventions and patents, taken either
singly or in combination, is seen to describe the instant invention
as claimed. Therefore, an elastic loop for securing a bag to a
trashcan solving the aforementioned problems is desired.
SUMMARY OF THE INVENTION
[0011] The elastic loop for securing a bag to a trashcan is an
elastic cord formed into a loop. The cord may be made as a
one-piece endless loop, or as a linear cord with its two ends
connected together by a coupler, e.g., a metal coupler crimped
together over the opposing ends to form a continuous loop. The
elastic cord is constructed of a plurality of elastic strands
wrapped tightly in a pliable tubular cover.
[0012] The continuous loop has a circumference less than the
circumference of a trashcan for which it is adapted but can be
stretched to fit tightly around the trashcan and thereby secure a
trash bag to the trashcan. A single embodiment of the device is
adapted for use with trashcans of variety of sizes.
[0013] Using the device, a trash bag is secured to a trashcan by
inserting the closed end of the trash bag into the trashcan and
folding the open end of the trash bag over the rim of the trashcan
such that a portion of the open end of the trash bag circumscribes
the exterior of an upper portion of the trashcan. The device is
then stretched around the portion of the trash bag folded over the
rim of the trashcan.
[0014] Accordingly, it is a principal object of the invention to
provide an elastic loop for securing a trash bag to the rim of a
trashcan.
[0015] It is another object of the invention to avoid slippage of a
trash bag down into a trashcan by providing an elastic loop for
securing a trash bag to the rim of a trashcan.
[0016] It is a further object of the invention to facilitate quick
and easy emptying of a trashcan lined with a trash bag by providing
an elastic loop for securing a trash bag to the rim of a
trashcan.
[0017] Still another object of the invention is to provide an
elastic loop for securing a trash bag to the rim of a trashcan in
order to avoid either having to transport a trashcan to a larger
container or having to invert a trashcan in order to empty the
trashcan of its contents.
[0018] A further object of the invention is to provide an elastic
loop for securing a trash bag to a trashcan which resists breakage
by providing the loop with multiple strands.
[0019] Further, it is an object of the invention to provide
improved elements and arrangements thereof for the purposes
described which is inexpensive, dependable and fully effective in
accomplishing its intended purposes.
[0020] These and other objects of the present invention will become
readily apparent upon further review of the following specification
and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] The present invention is an elastic loop for securing a bag
to a trashcan designated generally as 10 in the drawings. Referring
first to FIGS. 1-3 of the drawings, the invention includes an
elastic cord 12 and a coupler 20. The elastic cord 12 has two ends
13 and 14 which are disposed end-to-end and crimped together with
the coupler 20 to form a continuous elastic loop 10. In cross
section, the elastic cord 12 is round, as shown in FIG. 3, and
incorporates a plurality of elastic strands 11 wrapped tightly
together in a pliable tubular cover 15 or sheath. The diameter of a
cross section of the elastic cord 12 is between about one-quarter
of an inch and about {fraction (3/16)} of an inch.
[0033] The coupler 20, shown separately in FIGS. 4A-4C, is
constructed of metal. Prior to assembly of the invention, the crimp
20 has a rectangular bottom wall 21 and two substantially
rectangular sidewalls 22 and 23 joined to form a U-shaped channel.
The bottom wall 21 has four triangular gripping spikes 24
protruding upward from its top surface. The four triangular
gripping spikes 24 are formed by punching through the bottom wall
21 with a die adapted to form one or more triangular protrusions
from a flat piece of sheet metal. The two sidewalls 22 and 23
extend upward from opposite edges of the bottom wall 21 and are
substantially parallel to each other 22 and 23. The top edge 25 of
each sidewall 22 and 23 is serrated. When the crimp 20 is crimped
to the elastic cord 12, the four triangular gripping spikes 24
penetrate the elastic cord 12 to provide a secure crimp of the two
ends 13 and 14 and the crimp 20 adapts to the rounded shape of the
elastic cord 12.
[0034] It will be understood that the description of coupler 20 is
exemplary for purposes of enabling the invention, and not intended
to limit the scope of the present invention. Any other form of
coupler for joining together the two ends of a flexible cord known
to those skilled in the art may be used in lieu of the metal,
crimp-type coupler shown in the figures.
[0035] The pliable tubular cover 15 is constructed of a pliable
elastic material and can be a single color or a combination of
colors set in a pattern such as stripes.
[0036] When not stretched, the device 10 has a circumference less
than that of a trashcan for which it 10 is adapted. The device 10
is capable of being stretched to fit tightly around the rim of a
trashcan and to thereby secure a trash bag to the trashcan. Using
the device 10, a trash bag is secured to a trashcan by inserting
the closed end of the trash bag into the trashcan and folding the
open end of the trash bag over the rim of the trashcan such that a
portion of the open end of the trash bag circumscribes the exterior
of an upper portion of the trashcan. The device 10 is then
stretched around the portion of the trash bag folded over the rim
of the trashcan.
[0037] As shown in FIG. 5, an alternative embodiment 30 of the
invention is constructed without a crimp. In this embodiment 30, a
plurality of elastic strands is tightly wrapped in a looped tubular
cover.
[0038] FIGS. 6A-6C show an elastic loop 40 and in use with a
trashcan 50. Elastic loop 40 may have the structure of either loop
10 or loop 30. As shown in FIG. 6A, the trashcan 50 has a groove 51
circumscribing its sidewall near its rim 52. When not stretched,
the elastic loop 40 has a circumference less than that of the
groove 51. The elastic loop 40 is capable of being stretched to fit
tightly around the groove 51 and to thereby secure a trash bag to
the rim 52 of the trashcan 50.
[0039] It is to be understood that the present invention is not
limited to the embodiments described above, but encompasses any and
all embodiments within the scope of the following claims.
