BACKGROUND OF THE INVENTION
[0004] The present invention generally relates to a trashcan
assembly having bag engaging members for grasping and retaining a
trash bag.
[0005] The use of trashcan devices is known in the prior art. U.S.
Pat. No. 6,126,031, which is incorporated herein by reference,
describes a device having a bottom compartment for holding a roll
of trash bags so that the trash bags may be retrieved as needed
through an opening extending into the bottom compartment. Another
type of trashcan device is disclosed in U.S. Pat. No. 5,636,416,
which is incorporated herein by reference, which device has a
conventional shape and which includes clips that are attachable to
a trash bag. The clips are positioned outside of the trashcan to
prevent the trash bag from falling back into the trashcan. Another
clip assembly for securing a trash bag is found in U.S. Pat. No.
5,645,186, which is incorporated herein by reference.
[0006] While these devices fulfill their respective, particular
objectives and requirements, it is believed that a need remains for
a simple trashcan assembly that allows a trashcan liner--sometimes
referred to herein as a trash bag and vice versa--to be secured
directly to the trashcan assembly in order to prevent the trash bag
from slipping and falling into the trashcan assembly.

a rim of the container.
[0072] In a feature of this aspect, the step of forming the
container comprises molding the container. The molding may comprise
injection molding. Moreover, making the bag retention member may
include co-molding a frame and a flexible, resilient panel to the
frame so as to define the insert. In this scenario, the frame
preferably is formed from a first material and the panel is formed
from a second, different material. The step of forming the
container also may comprise injection molding the container, and
the container may be formed from a third material different from
the first and second materials or may be formed from the second
material from which the frame is formed.
[0073] In at least one embodiment of any one of the preceding
aspects, the container comprises a porcelain coated steel
member.
[0074] In addition to the aforementioned aspects and features of
the present invention, it should be noted that aspects of the
present invention further encompasses the various possible
combinations of such aspects and features. The invention also
encompasses methods of using and methods of making the
aforementioned container assemblies in accordance with such aspects
and features.

DETAILED DESCRIPTION
[0086] As a preliminary matter, it will readily be understood by
one having ordinary skill in the relevant art ("Ordinary Artisan")
that the present invention has broad utility and application.
Furthermore, any embodiment discussed and identified as being
"preferred" is considered to be part of a best mode contemplated
for carrying out the present invention. Other embodiments also may
be discussed for additional illustrative purposes in providing a
full and enabling disclosure of the present invention. Moreover,
many embodiments, such as adaptations, variations, modifications,
and equivalent arrangements, will be implicitly disclosed by the
embodiments described herein and fall within the scope of the
present invention.
[0087] Accordingly, while the present invention is described herein
in detail in relation to one or more embodiments, it is to be
understood that this disclosure is illustrative and exemplary of
the present invention, and is made merely for the purposes of
providing a full and enabling disclosure of the present invention.
The detailed disclosure herein of one or more embodiments is not
intended, nor is to be construed, to limit the scope of patent
protection afforded the present invention, which scope is to be
defined by the claims and the equivalents thereof. It is not
intended that the scope of patent protection afforded the present
invention be defined by reading into any claim a limitation found
herein that does not explicitly appear in the claim itself.
[0088] Thus, for example, any sequence(s) and/or temporal order of
steps of various processes or methods that are described herein are
illustrative and not restrictive. Accordingly, it should be
understood that, although steps of various processes or methods may
be shown and described as being in a sequence or temporal order,
the steps of any such processes or methods are not limited to being
carried out in any particular sequence or order, absent an
indication otherwise. Indeed, the steps in such processes or
methods generally may be carried out in various different sequences
and orders while still falling within the scope of the present
invention. Accordingly, it is intended that the scope of patent
protection afforded the present invention is to be defined by the
appended claims rather than the description set forth herein.
[0089] Additionally, it is important to note that each term used
herein refers to that which the Ordinary Artisan would understand
such term to mean based on the contextual use of such term herein.
To the extent that the meaning of a term used herein--as understood
by the Ordinary Artisan based on the contextual use of such
term--differs in any way from any particular dictionary definition
of such term, it is intended that the meaning of the term as
understood by the Ordinary Artisan should prevail.
[0090] Furthermore, it is important to note that, as used herein,
"a" and "an" each generally denotes "at least one," but does not
exclude a plurality unless the contextual use dictates otherwise.
Thus, reference to "a picnic basket having an apple" describes "a
picnic basket having at least one apple" as well as "a picnic
basket having apples." In contrast, reference to "a picnic basket
having a single apple" describes "a picnic basket having only one
apple."
[0091] When used herein to join a list of items, "or" denotes "at
least one of the items," but does not exclude a plurality of items
of the list. Thus, reference to "a picnic basket having cheese or
crackers" describes "a picnic basket having cheese without
crackers", "a picnic basket having crackers without cheese", and "a
picnic basket having both cheese and crackers." Finally, when used
herein to join a list of items, "and" denotes "all of the items of
the list." Thus, reference to "a picnic basket having cheese and
crackers" describes "a picnic basket having cheese, wherein the
picnic basket further has crackers," as well as describes "a picnic
basket having crackers, wherein the picnic basket further has
cheese."
[0092] Referring now to the drawings, one or more preferred
embodiments of the present invention are next described. The
following description of one or more preferred embodiments is
merely exemplary in nature and is in no way intended to limit the
invention, its implementations, or uses.
[0093] Turning now to FIGS. 1-2, three different trashcan
assemblies 200,300,400 are illustrated, which are all generally in
accordance with a first aspect of the present invention.
[0094] The trashcan assemblies 200,300,400 have many features in
common. For example, each trashcan assembly includes a trashcan
container 202 and an attachment member 204,304,404 that is received
on a rim 206 of the trashcan container 202 and that includes at
least one bag engaging member 208. The attachment member
204,304,404 generally resembles a band and has an inner diameter of
about fourteen inches. The attachment member 204,304,404 also
includes an annular recess (visible, for example, within the
attachment member 404 on the right in FIG. 2) within which the rim
206 of the trashcan container 202 is received. The rim 206 may be
received in a "press-fit" or "snap-fit" connection within the
attachment member 204,304,404, or may be adhered or otherwise
bonded to the attachment member 204,304,404 for permanent
attachment thereto.
[0095] The trashcan assemblies 200,300,400 also have
differentiating features. These features relate to the
circumferential side profiles of the attachment member 204,304,404
in each assembly. In this respect, the first illustrated trashcan
assembly 200 includes an attachment member 204 having a generally
uniform height; the second illustrated trashcan assembly 300
includes an attachment member 304 having a height that gradually
varies along the circumference of the trashcan container 202; and
the third illustrated trashcan assembly 400 includes an attachment
member 404 having a height that sharply increases in the areas of
the bag engaging members 208.
[0096] For each of the assemblies, the attachment member
204,304,404 preferably is injection molded from one or more
materials. The materials preferably comprise one or more
thermoplastic materials and/or one or more elastomers.
[0097] In some embodiments, the entirety of the attachment member
is made from the same material, i.e., a single source material, in
an injection molding process, and each bag engaging member 208 is
formed by simply forming openings 212 in the attachment member,
either during the injection molding process or thereafter. In other
embodiments, different portions of the attachment member
204,304,404 are formed from different source materials that are
co-molded together, i.e., the bag engaging members 208 are
preferably formed from a material that is more resilient and/or
more flexible than the material from which the remainder of the
attachment member 204,304,404 is formed.
[0098] As shown herein, the openings 212 have a generally X-shaped
configuration. However, it will be understood that in at least some
embodiments each opening 212 may have any configuration that
enables a bag engaging member 208 to grasp and retain a trash bag
when a portion thereof is inserted through the bag engaging member
208.
[0099] The bag engaging members 208 of any of the three trashcan
assemblies 200,300,400 may include any one of the different types
of bag engaging members that are disclosed in the incorporated
references, including U.S. patent application Ser. Nos. 11/424,920;
11/424,942; 11/424,968; and 11/424,969.
[0100] The containers 202 of each of the three trashcan assemblies
200,300,400 are identical. It is preferred that the container 202
comprise a porcelain coated steel member. However, the container
202 may comprise a different material such as plastic or any other
material conventionally used for forming trashcan containers. As
will be apparent from the exploded view of FIG. 2, "cutouts" 214
are provided about the rim 206 of the container 202 so that each
bag engaging member 208 provides access through the openings 212
therein into the interior of the container 202. Each cutout 214
generally corresponds to the area of the opening 212 of a bag
engaging member 208.
[0101] A trashcan assembly 500 in accordance with an embodiment of
another aspect of the invention is illustrated in FIG. 3. The
trashcan assembly 500 of FIG. 3 includes an outer container 502
having a hinged lid 504 as well as an interior container 506 that
is removably received within the outer container 502. The outer
container 502 preferably comprises a porcelain outer shell.
However, the container 502 may comprise a different material such
as plastic or any other material conventionally used for forming
trashcan containers.
[0102] The interior container 506 includes bag engaging members 508
that register with "cutouts" 510 in the rim 512 of the container
502 when the interior container 506 is received therein, as shown
in FIG. 3. Similar to the rim attachment member 204,304,404 of
FIGS. 1-2, the interior container 506--including the bag engaging
members 508--may be made in an injection molding process entirely
from the same material, or the interior container 506--including
the bag engaging members 508--may be made in an injection molding
process in which portions are co-molded together, wherein the bag
engaging members 508 are made from a material that is more
resilient and/or more flexible than the material from which the
remainder of the interior container 506 is made.
[0103] The bag engaging members 508 of the interior container 506
may include any of the different types of bag engaging members that
are disclosed in U.S. patent application Ser. Nos. 11/424,920;
11/424,942; 11/424,968; and 11/424,969.
[0104] In a variation of the foregoing trashcan assemblies
200,300,400,500, the "cutouts" 214,510 in the rim 206,512 of the
trashcan containers 202,502 of FIGS. 1-3 may be replaced with
openings that do not extend to the top of the containers. In this
variation, the top edge of the containers 202,502 thus may be
continuous within a plane.
[0105] Now turning to a second aspect of the present invention and
with reference to FIGS. 4-6 and 10, an insert 10 in accordance with
a second aspect of the present invention is illustrated. In this
regard, FIG. 4 illustrates a front perspective view of the insert
10; FIG. 5 illustrates a rear perspective view of the insert 10;
and FIG. 6 illustrates a side elevational view of the insert
10.
[0106] As perhaps best seen in FIG. 6, the insert 10 includes a
channel 26 that is formed in, and extends about, the periphery of
the insert 10. The insert further includes a front skirt portion 28
and a rear skirt portion 30. As illustrated, the periphery of the
insert 10 is generally circular, the channel 26 extends
continuously about the insert 10, and the skirt portions 28,30
likewise are generally circular and extend continuously about the
insert 10.
[0107] In accordance with the invention, the insert 10 includes a
liner engaging member (sometimes alternatively referred to as a
"liner engaging portion," a "bag engaging member" or a "bag
engaging portion") indicated generally by 12. The liner engaging
member 12 includes an arrangement of a plurality of fingers 14 that
extend in a generally radial direction from a central opening or
aperture 16. Together with the aperture 16, the fingers 14 define a
passageway through the liner engaging member 12.
[0108] The fingers 14 further are configured to receive and retain
a portion of a trash bag or liner when extended therethrough.
Moreover, each finger 14 preferably is bent or curved such that the
finger protracts (i.e., gently slopes) outwardly along a direction
from a distal end thereof toward a proximal end thereof located at
the aperture 16; and then retracts toward a rear of the liner
engaging member 12 such that the terminal end or tip 24 of the
finger 14 generally points toward the rear side of the liner
engaging member 12 (i.e., toward the interior space of a trashcan
when the liner engaging member is installed in a container as
shown, for example, in FIG. 8 discussed below). The fingers 14 at
their bends, i.e., at their "knuckles" 22, thereby serve to define
and bound the central opening or aperture 16. As defined thereby,
the aperture 16 may approximate the cross-sectional dimensions of
an average human finger.
[0109] The fingers 14 themselves are defined by a plurality of
slots 18 that also extend generally radially from the aperture 16.
The proximal end of each slot 18 connects to the aperture 16, while
each slot 18 includes a large rounded opening at its distal end
that serves a venting function for release of air that otherwise
may become trapped between a trashcan container 100 and a liner
when the liner is first placed within the trashcan for use.
[0110] Additionally, the slots 18 as illustrated define an open
space in the general shape of an "X," wherein the ends of the open
space are rounded or pear shaped. Additionally, each end of the
open space in the shape of an "X" may comprise an opening that is
approximately the size of the central opening 16 centrally located
between all of the terminal ends of the fingers 14.
[0111] Each finger 14, of which there are four in the illustrated
liner engaging member 12, preferably is resilient and flexible and
returns to the position shown in FIG. 4 after being deflected or
bent, such as may occur when a portion of a liner is inserted
through the passageway. The insert fingers 14 are shown in FIG. 10
in deflected positions as the result of a human finger being
inserted through the passageway in the direction of arrow A
generally along the axis of the central opening 16. When the human
finger is withdrawn, the insert fingers 14 return to the default
positions as shown in FIGS. 4-6.
[0112] In a variation of the liner engaging member 12, not shown,
the central opening 16 includes dimensions sufficient to receive
therein a person's finger without displacement of the insert
fingers 14. In such variation, the fingers 14 provide sufficient
friction with a liner inserted through the passageway so as to keep
the liner from slipping into a container during use. Sufficient
friction is provided by both the coefficient of friction of the
material used to form the fingers 14 and the surface area of the
fingers 14 that is in contact with the liner. In this latter
respect, the bending of the fingers 14 and their rearward extension
(which would be toward the interior space of a container) increases
the surface area of the fingers 14 that is in contact with the
liner compared to fingers lacking such bend and rearward
extension.
[0113] In another variation of the liner engaging member 12, not
shown, the slots 18 (but not the central aperture 16) are replaced
by areas of reduced thickness sections or walls and are formed from
an elastic material such that the fingers 14 are movable and
bendable relative to one another. In such alternative, these
elastic areas are more easily stretched and deformed than the
fingers 14. These elastic areas further may include openings that
serve the venting function of the slots 18 of the liner engaging
member 12.
[0114] In still other variations, the actual arrangement of the
fingers 14 and the three dimensional contours thereof (i.e., the
gradual sloping and then bending, etc.) may vary within the scope
of the present aspect. Moreover, in some embodiments, the fingers
of the liner engaging member may be generally coplanar with the
insert and aligned with a section of a peripheral wall of a
container and, thus, not include portions thereof protracting to
any substantial extent beyond the bounds of the planes of the skirt
portions of the insert. In such variations, the fingers would not
protract outside of the planes of the skirt portions but,
nevertheless, could still include bending with finger tips pointed
rearward. Moreover, for example, the fingers could be "L" shaped,
"J" shaped, or "T" shaped while still existing within the bounds of
the planes of the skirt portions of the insert. In accordance with
certain additional embodiments of this aspect of the invention, any
one of the different arrangements of fingers may be used as
disclosed, for example, in the incorporated references, including
U.S. patent application Ser. Nos. 11/424,920; 11/424,942;
11/424,968; 11/424,969; 60/891,931; 11/778,839; and 11/778,841;
U.S. Pat. No. 7,243,811; and U.S. Patent Application Publication
No. 2007/0034334 A1.
[0115] With particular reference now to FIGS. 7-9, installation of
inserts 108,110 in a trashcan container 100--and the resulting
trashcan assembly formed thereby--are described in detail. The
inserts may be installed during manufacture of the container or
during retrofitting of a conventional trashcan container.
[0116] In this respect, a trashcan container 100 is illustrated in
FIG. 7. As shown therein, two openings 104 have been cut, punched,
stamped, or otherwise formed in the wall 102 that forms the sides
of the container 100. The openings 104 are illustrated as generally
circular, but the invention is not limited to circular openings
and, as will be apparent to the Ordinary Artisan, any other profile
may be utilized as desired. The trashcan container 100 also may
include a different arrangement and number of openings other than
the two opposed openings 104 illustrated in FIGS. 7-9, as
desired.
[0117] The inserts 108,110 are identical to one another, and each
has a similar circular profile as each of the openings 104.
Additionally, each insert 108,100 is substantially the same as the
insert 10 of FIGS. 4-6 and 10 and, as such, a detailed description
of each insert 108,110 is not included herein other than to
acknowledge with reference to FIG. 9 that each insert 108,110
includes resilient bent fingers 114 having knuckles 122; a central
opening or aperture 116 bounded by the knuckles 122; a front skirt
128; and a rear skirt 130.
[0118] Each insert 108,110 is installed in the wall 102 of the
container 100 by forcing the insert 108,110 into a respective
opening 104 such that the section of the wall 102 defining the
respective opening 104 is received within the channel of the
respective insert. Such disposition of inserts 108,110 is
illustrated in FIG. 8. An insert 108,110 may be forced into an
opening 104 in a direction from outside to inside of the container
100 but, preferably, such insert is forced into the opening 104 in
a direction from inside to outside of the container. Such forcible
seating causes deformation of at least a portion the insert but,
due to the resilient nature of the insert, the insert quickly
recovers upon its seating within the opening 104. Additionally,
when properly seated in the opening 104, the front skirt 128 bounds
the opening on the exterior surface of the wall 102 of the
container 100, and the rear skirt 130 bounds the opening on the
interior surface of the wall 102 of the container 100. When
installed in the container 100, each insert 108,110 defines a
passageway into the interior space of the trashcan container for
receipt therethrough and retention therein of a portion of a
trashcan liner.
[0119] In variations of the container 100, not shown, the container
may have a round shaped periphery or an elliptical shaped periphery
rather than a generally rectangular shaped periphery like container
100. An insert 108,110 may be placed into an opening of a container
of any shape in the same way as described for container 100. In a
further variation of this aspect of the invention, the shape of the
insert may mimic the shape of the container. For example, for an
elliptically shaped container, the insert may also be elliptically
shaped.
[0120] The insert may be manufactured from a resilient, rubber-like
or plastic material and may constitute a single piece. The insert
also may be received within the opening of the peripheral wall in a
"press-fit" or "snap-fit" connection and, optionally, may be
adhered or otherwise bonded for permanent attachment to the
wall.
[0121] Based on the foregoing description, it will be readily
understood by those persons skilled in the art that the present
invention is susceptible of broad utility and application. Many
embodiments and adaptations of the present invention other than
those specifically described herein, as well as many variations,
modifications, and equivalent arrangements, will be apparent from
or reasonably suggested by the present invention and the foregoing
descriptions thereof, without departing from the substance or scope
of the present invention.
[0122] Accordingly, while the present invention has been described
herein in detail in relation to one or more preferred embodiments,
it is to be understood that this disclosure is only illustrative
and exemplary of the present invention and is made merely for the
purpose of providing a full and enabling disclosure of the
invention. The foregoing disclosure is not intended to be construed
to limit the present invention or otherwise exclude any such other
embodiments, adaptations, variations, modifications or equivalent
arrangements, the present invention being limited only by the
claims appended hereto and the equivalents thereof.
