Lowrance Attorney-Gustave Miller ABSTRACT: This garbage or trash can is a vermin-proof, tapered, rectangular open top container and cover, the container being nestable with similar containers for storage or shipping. The container is of heavy plastic, or of metal having an interior plastic coating. Sealing material is provided between the cover and the container for providing a verminproof closure on the container. The cover is held tightly against the container top either by resilient means, or by being of heavy material. When of heavy material, the cover is a one piece item, with handles, and a curved, recessed edge or lip complementary to an outwardly extending beaded edge on the container top edge. The heavy cover may also be provided with a plastic coating. When resilient means is provided for holding the cover on the container top edge, it may be an outer frame with a scalable lip resiliently securable on the container top edge by coil springs each fastened to outwardly extending ears on two opposite sides of the cover frame, linked chains depending from the coil springs, and a bifurcated boss extending from the container sides cooperates with the links of the chain. An inner cover hinged along one inner edge of the frame rests on an inwardly extending ledge on the bottom of the frame, and coil springs extend between ears on the bottom of the inner cover and on the bottom of the hinged side of the frame, with sealing material between the inner cover and the supporting ledge.
PATENTEBunv 9 IBYI SHEET 2 [1F 2 INVENTOR ATTORNIz'Y RECTANGULAR TAPERED NESTABLE WASTE CAN AND COVER BACKGROUND OF THE INVENTION While there are many types of waste containers, they generally lack means for keeping the cover thereon in verminproof sealed position while the cover is readily removable. The prior art covers are generally easily lost or separated from the container.
OBJECTS OF THIS INVENTION It is an object of this invention to provide an improved garbage or waste can and cover, wherein the cover may remain on the container and keep it vermin-proof.
A further object of this invention is to provide a waste receptacle that is easily maintained in vermin-proof condition.
A further object of this invention is to provide a waste receptacle having a container that has a smooth plastic interior capable of being easily cleaned, which may be of solid plastic, or may be of metal interiorly coated with a readily cleanable plastic.
A further object of this invention is to provide a waste receptacle having a container that is rectangular in cross section, and tapered outwardly toward its upper open top so that it may be nestable for storage or shipping.
A further object of this invention is to provide a container and cover wherein the cover is provided with a recessed lip complementary to the container top beaded edge, with sealing means between the lip and container beaded edge so that the receptacle may be closed into a vermin-proof condition.
BRIEF DESCRIPTION OF THE FIGURES With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing, in which:

FIG. 2 is a top plan view of FIG. 1.
FIG. 3 is a sectional view of the receptacle on line 3-3 of FIG. 2.
FIG. 4 is a perspective exploded view of another form of the waste receptacle of this invention.
FIG. 5 is a sectional view on line 5-5 of FIG. 4.
FIG. 6 is a sectional view on line 6-6 of FIG. 4.
DETAILED DESCRIPTION OF THE INVENTION There is shown at 10 one form of the waste receptacle of this invention, and at 12 another form of the waste receptacle of this invention, both forms 10 and 12 providing verminproof garbage or trash cans and covers.
In both forms 10 and 12, the cans or containers l4 and 16 are rectangular in cross section, and taper upwardly and outwardly toward their open tops so that the cans or containers 14 or 16 may be nested for storage or shipping.
As seen in FIG. 2, in the form 10, the can or container 14 is made of a suitable solid plastic material. On two opposite walls, adjacent the open top edges 18, there are provided outstanding bosses 20 pivotally supporting rectangular plastic or metal handles 22 which hang down when not in use, but which pivot up to a horizontal position against abutments 24 on the bosses 20 for conveniently manually carrying the receptacle l0.
Arranged to be secured against the top edge 18 of plastic can 14 is a two piece can cover 26, both pieces, an outer frame 28 and an inner cover 30, being made of the same plastic as the can 14. The outer frame 28 is provided with an upper outwardly extending lip 32 complementary to the top edge 18 of the can 14, and a sealing compressible material 34 is placed between the top edge 18 of the can and the bottom surface of the lip 32, and may also extend downwardly along the vertical edge 36 of frame 28 as shown, if desired. For convenience, this sealing compressible material 34 will preferably be secured to the bottom of frame lip 32 so as to provide an easily cleanable top edge 18 of the can 14.
The frame 28 is held in tight vermin-proof contact with the top edge 18 of the can 14 by being provided with an outwardly extending ear 38 on each of two opposite edges. A coil spring 40 hangs from each ear 38, and a linked chain 42 in turn depends from the coil spring 40. A bifurcated, downwardly slanted boss 44 extends from each of two opposite side walls of the can 14, and a handle loop 46 enables the chain 42 to be readily inserted into or pulled out of the bifurcated boss 44. When in the boss 44, the coil spring 40 resiliently fastens the frame 32 on the can top edge 18 in vermin-proof contact therewith. lnwardly extending from the frame 28 is a bottom ledge 48 for supporting an inner cover 30 thereon. A compressible sealing strip 52 is provided between the ledge 48 and the inner cover 30, being preferably secured in appropriate position on the bottom of the cover 30.
A hinge 54 is secured along one edge of the cover 30 and one inner top edge of the frame 28 so that the cover 30 may be manually opened by a handle 56 on the cover 30 for putting in garbage, trash or other waste material into the can 14. When the can 14 is reasonably full, it may be carried by the can handles 22 to the place of disposal, and then combined cover 30 and frame 28 is removed by means of two oppositely disposed handles 58 on the outer frame 28 after the chain handle loops 46 are pulled down to release the combined cover from the can 14, thus providing a maximum opening for removing the contents of the can 14. A resilient coil spring 60 secured to a depending car 62 from the bottom of the hinged side of frame 28 and an adjacent area on the bottom of cover 30 serves to resiliently urge inner cover 30 into vermin-proof contact with sealing strip 52 against ledges 48 of frame 28, thus permitting the inner cover 30 to be readily opened for placing waste material in the can 14, and then automatically holding the cover 30 in vermin-proof closed position.
In the form of receptacle 12, the can 16 is likewise rectangular in cross section and tapered upwardly and outwardly for easy nestability. However this can 16 is made of a suitable metal 66 coated on its interior surface with a suitable plastic 68, which may be the same plastic material as in the can 14, to provide an easily cleanable interior. At the bottom, the metal is bent upwardly and inwardly to provide a footing 70 supporting the can floor 72 at an elevation, particularly if the metal 68 is of ferrous metal, to prevent rusting when resting on a damp or wet surface. While the plastic 68 thus coats the interior of the metal 66 and the floor 72, it is installed after the footing 70 is formed. The plastic coating 68 stops a short distance below the top edge of this can 16, and in this case, a compressible sealing material 74 is coated on the top inside of the metal 66 which is then rolled into an edge bead 76. Below but adjacent the edge bead 76, handle bosses 78 are formed on or attached to the metal 66 of can 16 on two opposite walls, rectangular handles 80 being pivoted thereon and limited to horizontal lifted position by abutrnents 82 extending from the handle bosses 78.
Cooperative with the can 16 is a cover 84 which may consist of suitable heavy material coated with a suitable plastic 86 similar to that at 68. The lower edge or lip 88 is recessed complementary to the rounded bead 76 of can 16, and this recess or lip edge 88 may also be provided with a compressible sealing material 90. A handle 92 is provided for lifting the cover 84 so that waste material may be put into or taken out of the can 16. The cover 84 being rather heavy and extending into the can 16 with the sealing materials 90 and 74 contacting each other, a vermin-proof closure contact is necessarily provided by this receptacle 12 also.
