US 8,104,960 B2 · Sealable and disposable receptacle for biologic waste products

Abstract

A portable and sealable waste disposal receptacle receives human waste material through an opening in an outer chamber. The waste passes through an inner chamber, which is suspended within the outer chamber, and passes through a one-way valve located at the bottom of the inner chamber into a lower chamber portion of the outer chamber. The one-way valve is fashioned from the bottom edges of the inner chamber, where a biasing strip is mounted in compression along one of the bottom edges, which causes the bottom edges of the inner chamber to be biased closed in sealing contact except when waste enters the inner chamber, the weight of which is sufficient to overcome the closing bias of the biasing strip, allowing the waste to flow into the lower chamber. Once the waste has cleared the inner chamber, the biasing member causes the bottom edges to come together in sealing contact, preventing the flow of waste back through the inner chamber.

Dependent claims

A sealable waste disposal receptacle comprising:

an outer chamber comprising an outside surface, an inside surface, an open top and a closed bottom;
an inner chamber comprising a top, a bottom, a top opening, a bottom opening, the top opening in axial adjacency to the top of the outer chamber, the top sealingly attached to the outer chamber and depending there from and the bottom opening defined by a first edge and a second edge in parallel relation;
a lower chamber defined by the volume between the bottom opening of the inner chamber and the closed bottom of the outer chamber;
the bottom of the inner chamber comprising a first corner and a second corner wherein the first corner edge comprises a first pocket and the second corner comprises a second pocket;
and
a flexible member compressibly disposed between the first pocket and the second pocket, thereby applying sufficient force to the first corner and the second corner to bias the first edge and the second edge together in sealing contact.

A sealable waste disposal receptacle comprising:

an outer chamber comprising a flexible material impervious to water, an inside surface, an outside surface, an open top and a closed bottom;
an inner conduit comprising a flexible material formed into a first sheet and a second sheet, wherein the first sheet and second sheet each comprise a top edge, a bottom edge, and a first length-wise edge and a second length-wise edge, the first sheet and the second sheet having generally the same shape and dimensions and corresponding length-wise edges, wherein the length-wise edges of the first sheet and the second sheet are attached together, and the top edge of the first sheet and the corresponding top edge of the second sheet define a top opening and the bottom edge of the first sheet and the corresponding bottom edge of the second sheet define a bottom opening, the top opening in axial adjacency to the top of the outer chamber, the top edges of the first sheet and second sheet sealingly attached to the outer chamber and depending there from;
a lower chamber defined by the volume between the bottom opening of the inner conduit and the closed bottom of the outer chamber;
the bottom edge of the first sheet further comprising a first corner adjacent to the first length-wise edge and a second corner adjacent to the second length-wise edge wherein the first corner edge comprises a first pocket and the second corner comprises a second pocket;
and
a flexible member compressibly disposed between the first pocket and the second pocket, thereby applying sufficient force to the first corner and the second corner to place the bottom edge of the first sheet in tension such that the bottom edges of the first sheet and the second sheet are biased together in sealing contact.
