Disclosed herein is a waste storage device (100) comprising a receiving chamber (132) provided in an upper part of the device (100) and a rotator (136) rotatably mounted in the chamber (132). The rotator (136) comprises an upper annulus (154), and a cylindrical wall (150) extending downwardly from the upper annulus (154). The rotator (136) comprises at least one projection (151) extending therefrom, said at least one projection (151) being arranged to locate with at least one corresponding recess (171) on a waste storage cassette (172) to support the waste storage cassette (172) in the chamber (132) and to ensure rotational engagement between the rotator (136) and the cassette (172).

A cassette for use in dispensing a pleated tubing. The cassette comprises an annular body having a generally U shaped housing with a central cylindrical core. The at least one wall has an upper end with a downturn lip disposed thereon. An annular cover extends radially outward from the central cylindrical core over the annular body defining a gap. The cover has a socket into which the upper end with the downturn lip is secured. A tubing is disposed within the u-shaped housing and withdrawn from the gap.

Containers are described which can accommodate a variety of flexible bag assemblies used for containing waste. Internal accommodating structures are designed to accommodate and secure various types of bag assemblies, including single bag assemblies and cassettes.

A waste disposal system has a waste disposal device and cassette having a length of flexible film. The cassette has a lower surface and a guide feature enabling the cassette to rotate within the upper housing of the pail, maintain a substantially stationary position within the upper housing of the pail, or combinations thereof. The waste disposal device has a guide member that engages the guide feature of the cassette. The waste disposal device has a cassette housing and a sealing mechanism. One of the housing and sealing mechanism, and the cassette, rotate with respect to the other, either directly or indirectly.

A bag for holding trash, diaper, and any item that needs to be contained. The bag can have an enclosure body and a mouth opening where the opening is lined with a foldable frame. The foldable frame can fold out to keep the mouth opening in an open configuration, and can collapse upon itself to keep the mouth opening in a closed configuration. The foldable frame can optionally have a locking notch, a finger, or both, all of which can be used to attach to some part of the enclosure body thereby keeping the neck of the bag twisted closed. The bag can optionally have attachment points such as apertures, sleeves, strips, and loops for securing to the locking notch. In some embodiments, the collar need not be foldable.

A waste-disposal device for use with a bag unit of the type having an annular component from which a free end of tube extends to form a bag. The waste-disposal device comprises a bin having an open top end for accessing an inner cavity of the bin. A support is in the bin adjacent to the open top end and adapted to support the annular component of the bag unit for waste to be received in the bag of the bag unit extending in the inner cavity of the bin, by passing through a central opening thereof. A closing mechanism comprises a door pivotally connected to the support by at least one pivot and an abutment surface in the bin, a pivot axis of the at least one pivot being located at a same height or higher than a bottommost edge of the annular component of the bag unit when received in the support and when the bin has a bottom thereof on the ground. The door is pivotable between a closed position in which the door presses the bag toward the abutment surface to close the bag, and an open position in which the door is away from the abutment surface to open the bag.
