Waste storage device
First Claim
1. A waste storage cassette for use with a container, the container being separate from the cassette, the container having an annular disk mounted on and forming a portion of the container, with the annular disk portion of the container being separate from the cassette, the annular disk portion of the container having a plurality of engagement lugs being formed on and spaced around the annular disk portion of the container, the cassette comprising:
- (A) flexible waste storage tubing;
(B) a generally tubular cassette housing defining a bottom wall, an inner wall, and an outer wall of the cassette;
(C) a cassette funnel attached to the cassette housing, the cassette funnel defining a top wall of the cassette; and
(D) the top wall, the bottom wall, the inner wall, and the outer wall of the cassette defining a waste storage tubing receptacle therebetween, the inner wall of the cassette having a central portion through which, in use, the waste storage tubing passes, the cassette further including a plurality of apertures, wherein the apertures located on the cassette are shaped and spaced to cooperatively and removably engage the engagement lugs of the annular disk portion of the container.

Abstract
A waste storage device includes a container in which a cassette is mounted. Tubing is pulled through the centre of the cassette to store packages separated by twists. The cassette is rotated relative to the container to provide the twists between packages by virtue of a rotatable disk and user grip portion. The package is gripped against rotation by a gripper diaphragm and is guided towards a wall of the container by a guide diaphragm to prevent untwisting between packages.

5. A cassette for dispensing material usable for storage and disposal of used diapers or other personal waste, the cassette being engageable with and removable from a container that is separate from the cassette, the container having an annular disk mounted thereon and forming a portion of the container, with the annular disk portion of the container being separate from the cassette, and the annular disk portion of the container having an engagement lug on the annular disk portion of the container, and the cassette being capable of being removably engaged with the engagement lug of the annular disk portion of the container, comprising:
-
(A) the cassette having a cassette housing embodying a generally annular and generally tubular shape, the cassette having an inner wall, an outer wall, and a bottom wall defined by the cassette housing; (B) the cassette having a cassette funnel attached to the cassette housing and defining a top wall of the cassette; (C) the cassette housing having a hollow interior compartment; (D) the bottom wall of the cassette being attached to the inner wall of the cassette and to the outer wall of the cassette, and the cassette further including an aperture spaced and shaped such that the engagement lug of the annular disk portion of the container can cooperatively and removably engage in the aperture of the cassette; (E) the top wall of the cassette being generally annular in shape; (F) a generally annular slot in the top wall of the cassette; (G) a central opening extending through the cassette and having a generally circular cross-section, the central opening being at least partially defined by the inner wall of the cassette; and (H) a flexible tubular sheet having an inner sheet surface, the flexible tubular sheet being located in the hollow interior compartment, wherein; (1) the flexible tubular sheet is arranged such that the inner sheet surface surrounds the inner wall of the cassette; and (2) the flexible tubular sheet is removable from the hollow interior compartment through the annular slot of the cassette. - View Dependent Claims (6, 7, 8, 9)

10. A cassette for dispensing material usable for storage and disposal of used diapers or other personal waste, the cassette being engageable with and removable from an annular disk mounted on and forming a portion of a container that is separate from the cassette, wherein the annular disk portion of the container is separate from the cassette, the annular disk portion of the container having engagement lugs shaped and spaced thereon, comprising:
-
(A) a cassette housing having a generally annular and generally tubular shape, the generally annular shape of the cassette housing being centered on a cassette central axis extending transversely through the cassette, and wherein the cassette housing includes a hollow interior compartment extending entirely around the cassette central axis, the cassette further comprising; (1) the cassette housing defining a cassette inner wall having a generally circular cylindrical shape centered on the cassette central axis, the cassette inner wall having an inner wall inside surface, an inner wall outside surface, an inner wall top edge, and an inner wall bottom edge, the cassette inner wall having an inner wall radius measured from the cassette central axis to the inner wall inside surface, and the cassette inner wall having an inner wall circumference measured around the inner wall inside surface; (2) the cassette housing defining a cassette outer wall having a generally circular cylindrical shape centered on the cassette central axis, the cassette outer wall having an outer wall inside surface, an outer wall outside surface, an outer wall top edge, and an outer wall bottom edge, the cassette outer wall having an outer wall radius measured from the cassette central axis to the outer wall inside surface, the outer wall radius being greater than the inner wall radius; and (3) the cassette housing defining a cassette bottom wall attached adjacent to and extending between the inner wall bottom edge and the outer wall bottom edge, the cassette bottom wall having a bottom wall inside surface and a bottom wall outside surface, (4) the cassette further comprising a plurality of cassette apertures, wherein the cassette apertures are shaped and spaced so as to be adapted to permit; (a) cooperative engagement with and removal from the engagement lugs of the annular ring portion of the container; and (b) air to escape the hollow interior compartment through the bottom wall apertures of the cassette; (B) a cassette funnel attached to the cassette housing defining a top wall of the cassette having a generally annular shape centered on the cassette central axis, the top wall of the cassette defined by the cassette funnel having a top wall outside surface and a top wall inside surface, wherein the top wall of the cassette defined by the cassette funnel further comprises a generally annular slot providing access to the hollow interior compartment of the cassette from outside of the cassette; (C) a cassette central opening extending through the cassette and having a generally circular cross-section centered on the cassette central axis, the cassette central opening being at least partially defined by the inner wall outside surface; (D) the hollow interior compartment of the cassette being further defined by the inner wall inside surface, the outer wall inside surface, the bottom wall inside surface, and the top wall inside surface; and (E) a flexible tubular sheet located in the hollow interior compartment of the cassette, wherein; (1) the flexible tubular sheet has an inner sheet surface and an outer sheet surface; (2) the flexible tubular sheet has an inner sheet surface dimension determined by measuring the distance around the inner sheet surface of the flexible tubular sheet; (3) the inner sheet surface dimension of the flexible tubular sheet is greater than the inner wall circumference; (4) the flexible tubular sheet is arranged in the hollow interior compartment such that the inner sheet surface of the flexible tubular sheet circumscribes the cassette inner wall; and (5) the flexible tubular sheet is removable from the hollow interior compartment of the cassette through the annular slot of the cassette. - View Dependent Claims (11, 12, 13)
