A waste separation container for selectively separating and storing waste material includes a receptacle with an upper edge with slits in its opening upwardly to receive and hold a plurality of thin plastic bags in an open position. The slits are preferably defined by flexible lobes, contiguous one another and extending along the upper edge of the receptacle. Preferably, a closure for the receptacle is provided, that has specifically designated through apertures that allow for discernable placement of recyclable material in a correspondingly appropriate compartment or bag. The provision of strips of flexible material with lobes defining between them bag-retaining slits, either to be mounted on existing containers, on partitions for existing containers or holders to be placed in existing containers permits retrofitting of existing waste receptacles to accomplish the object of making easy the segregation of waste as it is generated.
A waste separation receptacle assembly comprising an open-topped bag holder of a size and shape to receive a plurality of open-topped bags made of thin, strong material, said bag holder having means along upper edges thereof for supporting an upper edge portion of each of a plurality of said open-topped bags to hold said bags open adjacent one another, said means comprising a plurality of spaced lobes defining between them openings opening through their uppermost portion, said openings being of a size to admit material at the upper part of said bags and to hold said material tightly between contiguous of said lobes, for holding a plurality of liner bags in a selectively variable arrangement.
In a container having an upper lip defining an open mouth and a detachable and re-attachable cover, said cover comprising a frame with an outer flange shaped complementarily to the perimeter of said upper lip and dimensioned to embrace and frictionally to engage said upper lip, said frame defining an opening, and a lid, pivoted to said frame at both ends of a center line of said lid, within said opening, being normally biased to a mouth closing position and adapted to be swung away from said mouth closing position to permit entry of material to one side or the other side of said mouth, the improvement comprising slots extending through said lip and opening upwardly therethrough, said slots being substantially aligned with said lid center line and each being of a width and depth to accommodate a part of upper margins of two thin plastic bags, another part of which margins of the two bags extends between said slots substantially parallel to one another, and another part of each of which margins is draped over said lip and held between said lip and said frame flange, whereby when said lid is swung in mouth-opening direction, material passed through the opening on one side of said center line passes into one bag, and material passed through the opening on the other side passes into the other bag.
In a container housing a plurality of thin, flexible, open-topped bags, a strip of flexible material around and defining the upper edge of an upwardly opening mouth of said container, said strip being adapted to hold an upper edge of each of said plurality of bags in open condition, said strip comprising a multiplicity of flexible lobes positioned uniformly around said open mouth, said lobes being contiguous one another, immediately adjacent edges of said lobes defining between them a bag-material receiving slit, said immediately adjacent edges lying in substantially the same plane, and said lobes being resiliently bendable out of said plane with respect to adjacent lobes to facilitate release of said bag material from said slit.
