Abstract
Abstract A receptacle and cover assembly for collecting lawn debris and the like and including structure for assisting transfer of compacted contents of the receptacle to expendable lawn trash bags and the like, comprising a main receptacle body section in the shape of an upwardly opening container having a skirt-like lower edge formation at the bottom of the receptacle body section for supporting it in upright position, and a removable cover member for the receptacle body section. The body section has a centrally open outer bottom wall portion extending inwardly from the side wall at a position spaced slightly above the lower edge formation providing a shelf-like ledge extending inwardly from the side wall, and a moveable bottom panel member forming a discharge assist piston which rests on shelf-like ledge formation and collectively therewith forms the bottom of the receptacle. The center opening in the bottom wall portion is large enough for passage of the operator's hand therethrough to manually engage and force the bottom panel member toward the open upper end of the receptacle when the cover is removed and an expendable debris collecting bag is fitted over the receptacle to facilitate transfer of the contents of the body section into the expendable bag.

A receptacle and cover assembly for collecting lawn debris and the like and including means for assisting transfer of the contents to expendable lawn trash bags and the like, comprising a main receptacle body section in the shape of an upwardly opening container having a lateral side wall terminating in a lip formation at the upper end thereof bounding the top opening and a lower edge formation at the bottom of the receptacle body section for supporting the same in upright position on a supporting surface, a removable cover member for said receptacle body section, the body section having a centrally open outer bottom wall portion extending inwardly from the side wall at a position spaced slightly above said lower edge formation defining an inwardly projecting shelf-like ledge extending inwardly from the side wall as an encircling formation bounding the center opening thereof, a moveable bottom panel member forming a discharge assist piston providing collectively with said outer bottom wall portion the bottom of the receptacle having its outer peripheral portions overlying the shelf-like ledge formation and collectively therewith forming the bottom of the receptacle, the center opening in said bottom wall portion being large enough for passage of the operator's hand therethrough to manually engage and force said bottom panel member from the bottom wall portion of said receptacle body section toward the open upper end thereof when the cover is removed and an expendable debris collecting bag is fitted over the receptacle body portion to facilitate transfer of the contents of the body section into the expendable bag, said receptacle body portion and said bottom wall portion being formed of resiliently deformable molded plastic material, said bottom panel member having catch formations integrally formed thereon, and said bottom wall portion having integrally formed slots for receiving and releasably interlocking with said catch formations for releasably restraining the bottom panel member latched to the bottom wall portion.
Claim 3
Dependent Claim
70 words
A refuse receptacle and cover assembly as defined in claim 1, wherein said main receptacle body section is of tapered cylindrical configuration tapering to a lesser diameter at said bottom edge, said bottom panel member is a thin circular disk, and said outer bottom wall portion is an annular ledge providing a center opening whose diameter is about half the diameter of the outer portion of said bottom wall formation.
Claim 4
Dependent Claim
63 words
A debris receptacle and cover assembly as defined in claim 2, wherein the portions of said lower edge portion adjacent the bottom edge of the main receptacle body section below the level of said bottom wall portion include a plurality of circumferentially elongated slot-like openings forming hand holes to receive fingers of the operator facilitating grasping and manipulation of the receptacle body section.
Claim 5
Dependent Claim
73 words
A debris receptacle and cover assembly as defined in claim 3, wherein said annular ledge formed by said bottom wall portion includes an annular upwardly convex intermediate deformation spaced radially outwardly of the perimeter of the center opening between said perimeter and the outer portions of the annular ledge formation providing a raised annular contact surface for supporting the circular disk along an annular zone spaced inwardly from the perimeter of the disk.
Claim 6
Dependent Claim
81 words
A debris receptacle and cover assembly as defined in claim 4, wherein said cover member has a pair of radially outwardly projecting, diametrically opposite handle formations extending outwardly from the circular perimeter thereof and having downwardly extending latch hook formations integral therewith normally urged to releasably latch beneath the upper lip of said main receptacle body section and being resiliently deformable upon upward deforming forces on said handle formations to release the same from latching relation with said upper lip formation.
Claim 7
Dependent Claim
73 words
A debris receptacle and cover assembly as defined in claim 2, wherein said annular ledge formed by said bottom wall portion includes an annular upwardly convex intermediate deformation spaced radially outwardly of the perimeter of the center opening between said perimeter and the outer portions of the annular ledge formation providing a raised annular contact surface for supporting the circular disk along an annular zone spaced inwardly from the perimeter of the disk.
Claim 8
Dependent Claim
101 words
A debris receptacle and cover assembly as defined in claim 2, wherein the cover member and the main receptacle body section are both formed of resiliently deformable flexible plastic material, and said cover member having a pair of radially outwardly projecting, diametrically opposite handle formations extending outwardly from the circular perimeter thereof and having downwardly extending latch hook formations integral therewith normally urged to releasably latch beneath the upper lip formation of said main receptacle body section and being resliently deformable upon upward deforming forces on said handle formations to release the same from latching relation with said upper lip formation.
Claim 9
Dependent Claim
62 words
A debris receptacle and cover assembly as defined in claim 1, wherein the portions of said lower edge formation adjacent the bottom of the main receptacle body section below the level of said bottom wall portion include a plurality of circumferentially elongated slot-like openings forming hand holes to receive fingers of the operator facilitating grasping and manipulation of the receptacle body section.
