Abstract
A waste container assembly is provided. The assembly includes an inner can with a closed bottom and an open top. A waste can liner can be placed in the inner can and the free edge of the liner can be folded over the open top of the inner can. The assembly further includes an outer enclosure that is telescoped around the inner can to conceal the inner can, the waste can liner and the contents of the waste can liner. For smaller cans, the outer enclosure has a unitary peripheral skirt and cover that can be telescoped over the inner can. Larger assemblies may have a separate cover and peripheral skirt. A lid is hinged to the cover and can be opened by a slight downward force on an inner portion of the lid. However, the lid is gravitationally biased to return to a closed condition.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates generally to waste cans, and specifically to a waste can that conceals the waste can liner and any waste therein.




2. Description of the Related Art




The prior art includes many waste cans with a bottom wall, an upstanding side wall enclosure and an open top. The side wall enclosure of prior art waste cans have been provided in many cross-sectional shapes, including, circular and elliptical. Many waste cans are used at locations where they are readily visible. Hence, there is a desire to make waste cans aesthetically attractive.




Most people protect the interior of the waste can from stains or other damage by employing a waste can liner. Waste can liners are plastic bags dimensioned to occupy a volume greater than the volume of the waste can. Thus, the plastic waste can liner is placed in the waste can and top edges of the liner are folded over the side wall of the waste can adjacent the open top. The liner protects the interior of the waste can from stains or damage with sufficient effectiveness. However, the contents of the waste can normally are not concealed by the liner. Furthermore, the hanging edges of the bag-like liner are unattractive and conceal attractive features and/or colors that may have been designed into the can. Additionally, the plastic liners often collapse into the waste can, and trash deposited after such a collapse is likely to be trapped between the liner and the waste can.




Many prior art waste cans include a cover. The cover often is locked to the side wall of the waste can adjacent the open top to prevent inadvertent separation. This feature provides security, but complicates access to the interior of the waste can for replacing a filled liner with an empty liner. Many such covered waste cans place the cover over the upper ends of the side walls after the liner has been placed in the open-top. Thus, the cover is effective for sealing the contents of the waste can but still shows the unattractive free edges of the plastic waste can liner.




Many covered waste cans include a hinged lid in the cover. The hinged lid is intended to facilitate placement of waste into the can. However, covers that include a lift-up lid are inconvenient. More particularly, consumers would prefer to merely throw or otherwise move the trash downwardly into the trash can without the separate step of first lifting the lid upwardly. Waste cans with lids incorporated into the covers typically do not solve the problem of peripheral regions of the waste can liner hanging over the top edge of the waste can and below the attached cover (see U.S. Pat. No. 5,295,605 and U.S. Pat. No. 5,651,231).




The prior art includes waste can systems where an inner trash-receiving can is disposed within an outer can assembly. For example, U.S. Pat. No. 5,183,175 shows a simple cylindrical open-topped inner can mounted in and extending partly above a cross-sectionally larger cylindrical open-topped outer can. A cover with a lid then is telescoped over the open tops of the inner and outer cans. The patent does not show how or whether plastic bags would be used with the disclosed waste can system. However, the close proximity of the telescoping edges of the inner and outer cans and the cover would suggest that any waste can liner would be folded over the top of both the inner and outer cans. Any other arrangement would require the user to manually lift the inner can out of the outer can, fold the top edges of the plastic bag into place and then carefully position overhanging portions of the plastic waste can liner into the narrow space between the inner and outer cans.




U.S. Pat. No. 4,961,514 shows an even more complex assembly that has an inner can positioned on a short base. A long cover then is telescoped over virtually all of the inner can and is locked into engagement with the base. The cover includes an opening to access the interior of the inner can but has no lid for closing the cover. This arrangement presumably would conceal any plastic liner used with the system. However, the contents of the liner could be readily viewed through the opening.




In view of the above, it is an object of the subject invention to provide a waste container assembly that conceals the contents of the assembly.




Another object of the subject invention is to provide a waste container assembly that conceals all portions of the waste can liner that is placed in the assembly for receiving the waste.




An additional object of the subject invention is to provide a waste container assembly that prevents the waste can liner from falling into the waste container.




A further object of the subject invention is to provide a waste container assembly with a hinged cover that facilitates deposit of trash into the waste can liner.




Still another object of the subject invention is to provide a hinged lid on a waste container assembly that facilitates depositing of trash into the assembly without lifting the lid and that enables closure of the lid without springs or other stored energy devices.




SUMMARY OF THE INVENTION




The subject invention is directed to a waste container assembly that comprises an inner can having a bottom wall, an upstanding side wall enclosure and an open top. The bottom wall of the inner can and the open top of the side wall may define identical or similar shapes. However, the open top of the side wall may be slightly larger than the bottom wall in view of molding efficiencies. The bottom wall and the open top edge of the side wall may be any convenient and desired shape. However, a substantially oval shape is preferred in view of aesthetics and functionality of the assembly as described further herein.




The waste container assembly further includes an outer enclosure for substantially completely concealing the inner can and the contents of the inner can. The outer enclosure comprises a peripheral skirt with an open bottom and a top. The open bottom of the peripheral skirt is disposed at or near the closed bottom of the inner can when the outer enclosure is assembled with the inner can. In certain embodiments, the peripheral skirt is dimensioned to terminate a short distance from the floor or other supporting surface for the waste container assembly. In other embodiments, the peripheral skirt extends entirely to the floor.




The outer enclosure further includes a cover that extends upwardly from the peripheral skirt and covers the open top of the inner can. The cover may be unitarily formed with the top end of the peripheral skirt. Alternatively, the cover may be formed separately from the peripheral skirt and may telescope over the top ends of the peripheral skirt and the inner can. This latter embodiment is particularly effective for dimensionally large waste container assemblies and avoids the need to lift a large outer enclosure for removing a full plastic trash can liner and inserting a new trash can liner.




The cover is provided with a hinged lid for accessing the interior of the inner can. The hinged lid extends from a peripheral side region of the outer enclosure to a location spaced inwardly from the side walls. A hinge for the lid is intermediate these inner and outer extremes of the lid. More particularly, the hinge and the lid are configured such that inner portions of the lid can be rotated downwardly for depositing trash into the trash receptacle assembly. However, the lid is configured and the hinge is disposed such that the lid is gravitationally biased toward a closed position. Thus, the lid can be open by urging the inner portion of the lid downwardly. These forces can be generated by hand or by the weight of the object that is being discarded. Upon release of those forces, however, the lid will swing gravitationally back to the closed position. Thus, both the opening of the lid and the closing of the lid are assisted by gravity, and the lid functions much in the manner of a seesaw that is slightly biased in one direction. Either a manual force or a force due to the weight of the trash will overcome the slight gravitational bias toward the closed position and will swing the lid into the open position for gravitationally depositing trash into the inner can of the assembly. The lid then will pivot back toward the closed position due to the forces of gravity and the relative position of the hinge. Thus, neither the opening nor the closing of the lid require any forces by the user other than the forces for depositing the trash into the receptacle.




The inner can is intended for use with a plastic waste can liner. More particularly, the closed end of the plastic waste can liner is placed in the inner can and the open top edges of the plastic waste can liner are folded slightly over the open top of the inner can. The open top of the inner can preferably is provided with a plurality of V-shaped notches. Edge regions of the plastic waste can liner can be bunched together and urged into one or more of the V-shaped notches to facilitate retention of the top edge of the liner in proximity to the open top of the inner can. Thus, the problematic collapsing of the liner into the can is completely avoided. Edge regions of the can are concealed by the outer enclosure. Thus, the user would not see the unattractive free edge of the trash can liner at any time other than when the liner is being removed and replaced.




The cover of the outer enclosure may comprise a substantially downwardly and rearwardly slanted portion and an upwardly and rearwardly slanted portion that intersect. The lid may be disposed on the downwardly and rearwardly slanted portion, and the upwardly and rearwardly slanted portion may include an opening. The intersection of these slanted surfaces provides an efficient target for a user. Thus, a user is likely to deposit trash near the intersection, and hence at a location on the cover that applies a maximum moment to the cover. This moment ensures sufficient forces to overcome the gravitational bias of the cover toward the closed position. Additionally, the proximity of the lid to the opening in the upwardly and rearwardly slanted portion of the cover facilitates accommodation of relatively large items of trash. Additionally, these intersecting surfaces at the upper end of a generally cylindrical or prismatic structure provides an aesthetically attractive appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A waste container assembly in accordance with a first embodiment of the invention is identified generally by the numeral


10


in

FIGS. 1-6

. The waste container assembly


10


includes an inner can


12


and an outer enclosure


14


.




The inner can


12


is molded unitarily from plastic and includes an oval bottom wall


16


. A side wall enclosure


18


extends up from the bottom wall


16


to define an external height “a” for the inner can


12


. The side wall enclosure


18


has an oval top edge


20


with a plurality of V-shaped notches


22


extending a short distance toward the bottom wall


16


. The notches


22


are dimensioned to releasably grip portions of a waste can liner in proximity to the free edges of the waste can liner as explained further below.




The outer enclosure


14


in accordance with the first embodiment comprises a peripheral skirt


24


and a cover


26


that are unitary with one another and molded from plastic. The outer enclosure


14


further includes a lid


28


that is hingedly mounted to the cover


26


of the outer enclosure


14


, as explained below.




The peripheral skirt


24


is of generally oval tubular shape with an open bottom


30


and a cross-sectional configuration to permit the outer enclosure


14


to be telescoped over the inner can


12


. The cover


26


of the outer enclosure


14


has a top


32


at an end of the outer enclosure


14


remote from the open bottom


30


. The outer enclosure


14


further includes a front


34


, opposed left and right sides


36


and


38


and a rear


40


. As explained further below, the front


34


defines the portion of the outer enclosure


14


that will face a user who is depositing trash in the waste container assembly


10


.




The cover


26


of the outer enclosure


14


includes an oval tubular side wall


42


that extends upwardly from the peripheral skirt


26


. However, the side wall


42


of the cover


26


is cross-sectionally slightly smaller than the peripheral skirt


24


. Hence, a step


44


is defined between the peripheral skirt


24


and the side wall


42


of the cover portion


26


. The boundary


44


is of generally sinusoidal shape around the circumference of outer enclosure


14


, as shown most clearly in

FIG. 3. A

valley of the sinusoidal step


44


aligns symmetrically with the lid


28


on the front


34


of the outer enclosure


14


. The step


44


is provided primarily for aesthetic purposes. However, the valley of the step


44


that is symmetrically aligned with the lid


28


helps to focus the user on the section of the waste container assembly


10


to which waste will be deposited.




The side wall


42


of the cover


26


includes a top edge


46


that effectively defines a plane aligned at an acute angle to a vertical axis through the side wall


42


. More particularly, portions of the top edge


46


at the rear


40


of the outer enclosure


14


are spaced a maximum distance from the bottom edge


30


, whereas portions of the top edge


46


of the side wall


42


near the front


34


are spaced a minimum distance from the bottom edge


30


.




Portions of the side wall


42


at the front


34


of the outer enclosure


14


are further characterized by a lid recess


48


. The lid recess


48


includes linear vertical side edges


50


and


52


that extend downwardly from the top edge


46


and a concave upwardly facing edge


54


that extends between the linear side edges


50


and


52


. The concave upwardly facing edge


54


is symmetrical with the valley in the sinusoidal step


44


at the front


34


of the outer enclosure


14


. This symmetry provides aesthetic appeal and also functions to target the user's attention at the proper location on the waste container assembly


10


for depositing trash.




The cover


26


of the outer enclosure


14


is further characterized by a top rear wall


56


that extends upwardly and forwardly from the top edge


46


of the side wall


42


across a region extending from the sides


36


and


38


and the rear


40


of the outer enclosure


14


. The top rear wall


56


is concave from side-to-side and slightly concave from front-to-rear. Additionally, the top rear wall


56


terminates at a boundary edge


58


which is rearwardly of a plane passing vertically and symmetrically through the sides


36


and


38


of the outer enclosure


14


. Thus, the top rear wall


56


effectively defines a sector of an ellipsoid.




The cover


26


of the outer enclosure


14


is further characterized by left and right top front walls


60


and


62


. The left and right top front walls


60


and


62


are partly defined by portions of the top edge


46


of the side wall


42


that extend from the left and right respective sides


36


and


38


toward the front


34


of the outer enclosure


14


. Additionally, the left top front wall


60


is defined further by a left inner side edge


64


that extends linearly rearwardly from the left side edge


50


of the front lid recess


48


. Similarly, the right top front wall


62


is defined partly by a right side edge


66


that extends rearwardly from the right side edge


52


of the lid recess


48


. The top front walls


60


and


62


slope downwardly at locations further from the extreme sides


36


and


38


of the outer enclosure


14


.




Hinge support walls


68


extend vertically downwardly from the inner side edges


64


and


66


of the respective top front walls


60


and


62


, as shown most clearly in FIG.


5


. The hinge support walls


68


are formed with hinge pins


70


and with stop pins


72


.




A connecting wall


74


extends downwardly and forwardly from the boundary edge


58


at the top


32


of the outer enclosure


14


. The connecting wall


74


intersects the left top front wall


60


at intersection


76


and intersects the right top front wall


62


at intersection


78


. The connecting wall


74


is further characterized by a concave arcuate opening edge


80


that extends between the inner side edges


64


and


66


of the left and right top front walls


60


and


62


respectively.




The outer enclosure


14


is further characterized by vertically aligned inner support walls


82


that extend inwardly from the side wall


42


. The inner support walls


82


include a notched bottom supporting edges


84


which are disposed on a common plane that is aligned parallel to the bottom edge


30


of the peripheral skirt


24


. Additionally, the bottom edges


84


of the support walls


82


are spaced from the bottom edge


30


of the peripheral skirt


24


by a distance “b” that is slightly less than the height “a” of the inner can


12


. The support walls


82


extend sufficiently inwardly to ensure engagement on the top edge


20


of the inner can


12


. Thus, the support walls


82


support the outer enclosure


14


with the bottom edge


30


spaced slightly above the floor or other surface on which the bottom


16


on the inner can


12


is supported. This configuration ensures that the weight of the outer enclosure


14


will engage portions of a trash can liner that drape over the top edge


20


of the inner can


12


for preventing the trash can liner from falling into the inner can


12


.




The lid


28


includes a top wall


86


with parallel left and right side edges


88


and


90


that fit between the inner side edges


64


and


66


of the respective left and right top front walls


60


and


62


. The top wall


86


further includes a rear edge


92


that connects the side edges


88


and


90


. The rear edge


92


defines a continuous extension of the intersections


76


and


78


when the lid


28


is mounted properly on the cover


26


. The top wall


86


of the lid


28


is concave from side-to-side and is configured such that the top wall


86


of the lid


28


and the top front walls


60


and


62


define a continuous concave surface in front of the connecting wall


74


.




The lid


86


further includes a front wall


94


that extends downwardly from the top wall


86


and fits closely into the lid recess


48


. The front wall


94


of the lid


28


is convex and continuous with portions of the side wall


42


of the cover


26


at the front


34


of the outer enclosure


14


. The front wall


94


includes a bottom edge


96


configured to abut the upwardly facing edge


54


of the lid recess


48


as shown most clearly in FIG.


5


.




The lid


28


is characterized further by hinge pin mounts


98


that are dimensioned to mount pivotally on the hinge pins


70


of the cover


26


. Thus, the lid


28


is capable of limited hinged movement relative to the cover


26


. The limitations on this pivotal movement are provided by the engagement between the bottom edge


96


of the front wall


94


of the lid


28


with the upwardly facing edge


54


of the lid recess


48


. Additionally, the stop pins


72


on the inner side wall


68


limit the movement of the rear edge


92


of the lid


28


downwardly into the inner can


12


.




As shown most clearly in

FIG. 5

, the hinge pin


70


and the hinge pin mount


98


are closer to the front wall


94


of the lid


28


than to the rear edge


92


thereof. This relative position enables a very large opening for depositing trash into the waste container assembly


10


. However,

FIG. 5

also shows that portions of the top wall


86


of the lid


28


between the hinge pin mount


98


and the rear edge


92


are thinner than portions forwardly of the hinge pin mount


98


. Furthermore, the front wall


94


also contributes to the mass of the lid


28


forwardly of the hinge pin mounts


98


. These relative thicknesses and dimensions are selected carefully to ensure that the mass of the lid


28


forwardly of the hinge pin mounts


98


exceeds the mass of the lid


28


rearwardly of the hinge pin mounts


98


. As a result, the lid


28


is gravitationally biased toward the closed position shown in FIG.


5


and is precisely in an alignment where the top wall


86


and front wall


94


of the lid


28


align with adjacent structural elements on the cover


26


to define a smooth continuous top and front surface. However, the relative masses forwardly and rearwardly of the hinge pin mounts


98


are very close to one another. Hence, a minor force on the top wall


86


near the rear edge


92


will cause the lid


28


to swing easily into the open position for depositing trash into the inner can


12


.




The waste container assembly


10


is used by initially lifting the outer enclosure


14


from the inner can


12


. A plastic waste can liner then is placed in the inner can


12


and the open edges of the waste can liner are draped over the top edge


20


of the inner can


12


. Portions of the waste can liner adjacent its open edges may be urged into the V-shaped notches


22


in the top edge


20


for securely but releasably holding the trash can liner and preventing the trash can liner from collapsing into the inner can


12


. The outer enclosure


14


then is telescoped over the inner can


12


and the trash can liner therein. This telescoping movement terminates when the bottom edges


84


of the inner support walls


82


are supported on the top edge


20


of the inner can


12


. This support further helps to prevent a collapsing of the trash can liner into the inner can


12


. In this assembled condition, the open edge of the waste can liner is completely concealed from view by the outer enclosure


14


. Furthermore, the lid


28


and the angular alignment of the connecting wall


74


and the positioning of the opening


80


therein substantially obscures all view of the contents of the inner can


12


.




The waste container assembly


10


may be used by merely depositing an item of waste onto the top wall


86


of the lid


28


at any location a significant distance rearwardly of the hinge pins


70


. This downward force caused by the object that is being discarded will cause the rear edge


92


of the lid


28


to pivot downwardly. In view of the forward position of the hinge pin supports


98


a relatively wide opening for receiving trash is ensured. This wide opening is enhanced by the opening


80


in the connecting wall


74


. Users of the assembly will be guided toward the rear edge


92


of the lid


28


by the presence of the opening


80


and by the unique arcuate configurations of the intersecting surfaces of the cover


26


. Additionally, the opening movement of the lid


28


is consistent with the depositing direction of the trash. Thus, the user does not have to lift the lid in a first direction and deposit the trash in a second direction. Once the trash is deposited, gravitational forces will cause the lid


28


to swing automatically and completely into the closed position due to the greater mass of the lid


28


forwardly of the hinge pin mounts


98


. This greater mass is achieved by the greater thickness of the top wall


86


forwardly of the hinge pin mounts


98


and by the existence of the front wall


94


.




Once the trash can liner in the inner can


12


has been filled, the user need merely lift the outer enclosure


14


from the inner can


12


. The open edge regions of the waste can liner then are collected and secured, and the closed waste can liner is discarded in a conventional manner. A new waste can liner then can be positioned in the inner can as described above.





FIGS. 7-10

show a waste container assembly


110


that is intended for a greater volume of trash. As a result, there are a few minor differences to facilitate assembly and disassembly and to facilitate insertion and removal of waste can liners.




As in the first embodiment, the waste container assembly


110


includes an inner can


112


and an outer enclosure


114


. The inner can


112


includes an oval bottom wall


116


and an oval tubular side wall


118


that extends upwardly to a top edge


120


. However, portions of the side wall


118


in proximity to the top edge


120


are enlarged outwardly to define a step


121


. Portions of the side wall


118


adjacent the top edge


120


further are provided with V-shaped notches


122


for gripping a trash can liner.




The outer enclosure


114


includes a peripheral skirt


124


and a cover


126


substantially as described above with respect to the first embodiment. Additionally, the cover


126


is formed with a lid


128


. Substantially the entire cover


126


and the lid


128


are identical to the cover


26


and lid


28


described and illustrated above. Hence, a detailed description of those identical components is omitted herein. One significant difference between the cover


126


of the second embodiment and the cover


26


of the first embodiment is the absence of internal support walls on the cover


126


that would correspond to the internal support walls


82


on the cover


26


. Additionally, the cover


126


and the peripheral skirt


124


are formed separately from one another, as shown most clearly in

FIGS. 7 and 8

. This separate construction is not immediately apparent on the assembled waste container assembly


110


, and on an initial inspection, the waste container assembly


110


merely appears to be a larger version of the waste container assembly


10


.




The peripheral skirt


124


includes an open bottom


130


and an open top


131


. The edges defined by the open bottom and top


130


and


131


are substantially parallel to one another. Additionally, the internal cross-sectional dimensions at the open top


131


are slightly greater than the outside cross-sectional dimensions of the side wall


118


of the inner can


112


at locations below the step


121


. However, the outside cross-sectional dimensions of the inner can


112


at locations above the step


121


exceed the inside cross-sectional dimensions at the open top


131


of the peripheral skirt


124


. Hence, the inner can


112


can be nested into the top of the peripheral skirt


124


, and the step


121


will be supported on the edge defined by the open top


131


of the peripheral skirt


124


. The peripheral skirt


124


defines a height “c” which is slightly greater than the vertical distance between the bottom wall


116


and the step


121


of the inner can


112


. Hence, the bottom wall


116


of the inner can will be supported slightly above the floor or other surface on which the open bottom


130


of the peripheral skirt


124


is supported.




The peripheral skirt has a front


134


, sides


136


and


138


and a rear


140


. Hand grip recesses


141


extend into the sides


136


and


138


at locations adjacent the open top


131


.




Portions of the peripheral skirt


124


adjacent the open top


131


are cross-sectionally slightly smaller than portions of the peripheral skirt extending upwardly from the open bottom


130


. These cross-sectional differences occur at a sinusoidal step


144


in proximity to the open top


131


. The sinusoidal step


144


resembles the sinusoidal step


44


on the outer enclosure


14


of the first embodiment. The hand grip recesses


141


are adjacent to but beneath both the open top


131


and beneath portions of the sinusoidal step


144


at the sides


136


and


138


.




The cover


126


includes a side wall


142


that is dimensioned to telescope over both portions of the inner can


112


adjacent the open top


120


and over the cross-sectionally small portions of the peripheral skirt


124


between the top edge


131


and the sinusoidal step


144


. Additionally, side wall


142


includes a sinusoidally generated bottom edge


143


that is dimensioned to nest with a sinusoidal step


144


.




The waste container assembly


110


is used by placing a waste can liner in the inner can


12


and folding the open edges of the waste can liner over the open top


120


of the inner can


12


. Portions of the plastic of the waste can liner can be releasably engaged in the V-shaped notches


122


to prevent the waste can liner from collapsing into the inner can


112


. The inner can


112


with the waste can liner therein then can be telescoped into the open top


131


of the peripheral skirt


124


. As shown in

FIG. 8

, the step


121


in the sidewall


118


of the inner can


112


will seat on the open top


131


of the peripheral skirt


124


and will project slightly over the hand grip recesses


141


. Thus, a user can readily grip the step


121


of the inner can


112


at the hand grip recesses


141


for removing the inner can


112


if necessary. The cover


126


then is telescoped over the open top


120


of the inner can and over portions of the open top


131


of the peripheral skirt


124


. As shown in

FIG. 9

, the bottom end


143


of the side wall


142


of the cover


126


will be positioned above the hand grip recesses


141


of the peripheral skirt


124


to facilitate a subsequent removal of the cover


126


.




As in the preceding embodiment, the cover


126


conceals portions of the waste can liner folded over the open top


120


of the inner can


112


. Thus, the unsightly waste can liner is not viewed from the exterior of the waste container assembly


110


. Additionally, the contents of the waste can liner are concealed by the cover


126


.




Trash is deposited into the waste receptacle assembly


10


substantially in exactly the manner described with respect to the first embodiment. More particularly, the mass distribution of the lid


128


enables trash to be deposited merely by exerting a slight downward force on the rear edge of the lid


128


. The lid


128


then will gravitationally return to the closed position shown in the figures.




The full waste receptacle liner can be removed from the inner can


112


merely by lifting the cover


126


from the peripheral skirt. The open edges of the liner then can be gathered together and the liner can be lifted from the inner can


112


. A new liner can be positioned in the inner can


112


with the open top edges folded over the open top


120


of the inner can


112


, as described above. Gathered portions of the liner can be secured in the V-shaped notches


122


. Finally, the cover


126


can be telescoped over the open top


120


of the inner can


112


and over the open top


131


of the peripheral skirt


124


.




While the invention has been described with respect to certain preferred embodiments. It is apparent that various changes can be made without departing from the scope of the invention as defined by the appended claims. For example, the waste receptacle assembly can have cross-sectional shapes other than the preferred oval shape shown herein.
