A cassette to dispense a pleated tubing. The cassette includes a circular body having an annular channel housing with a central cylindrical core. At least one wall has an upper end with a lip disposed thereon. An annular cover is attached to the lip at the upper end defining a gap over the annular body. A tubing is disposed within the annular channel housing and withdrawn from the gap. At least one of a plurality of apertures is provided at a lower end of the annular channel housing. The apertures have reinforced walls. The apertures are adapted to be aligned with a projection extending upward from within a container.

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 bag-closing device is disclosed which is capable of using general-purpose bags and which keeps the loss of capacity to the necessary minimum, and a shredder is provided which, even when shredded pieces of trash are stored in a bag, does not cause scattering of the shredded pieces of trash when closing the bag. The bag-closing device comprises one pair of horizontally facing winding shafts having tip parts for detachably holding a bag, which is open so as to allow objects to be put inside, at two facing opening edge parts from the outside of the bag, whereby the entire opening edge of the bag containing objects put therein is formed into a single horizontal roll-like shape by driving the one pair of winding shafts to rotate. In addition, the device may be provided with a cabinet, which allows a frame having one pair of winding shafts to be stored therein and to be pulled out therefrom together with a bag in an open state, and configured such that the one pair of winding shafts are restricted from rotating when the frame is pulled out from the cabinet whereas the one pair of winding shafts are allowed to rotate when the frame is placed in the cabinet. It is also feasible to construct a shredder having this bag-closing device installed below a shredding unit. In this case, preferably outer peripheral surfaces at the tips of the winding shafts are formed into a tapered shape.

A waste disposal container of smaller shipping profile is disclosed with an inner rotating support structure and an outer casing, where the inner rotating support structure and/or the outer casing may be shipped in separable parts and reassembled by the end consumer. The inner rotating support structure also may offer at least one bag attachment points to hold on to the body of the bag where the bag attachment points are designed to be lower to accommodate collection of cat litter.

A cassette to dispense a pleated tubing having an annular body, an annular cover and a plurality of apertures. The annular body may have a generally U-shaped housing with a central cylindrical core. The annular cover may extend over the annular body and define a gap, while being secured to the body. The plurality of apertures may be radially provided in an angular wall in the annular body.

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.

A sealing mechanism for a waste storage container includes a waste storage container that has a body, a lid and a cartridge adapted to be positioned in the body. The cartridge has a continuous length of storage film therein. The storage film emanates through a gap between a rim and a core tube of the cartridge and is folded down through a core opening in the core tube into an interior space of the body of the waste storage container. The sealing mechanism includes an actuator accessible from outside the body, a gear assembly operably connected to the actuator, a retaining assembly that holds stationary a dispensed portion of the storage film in the interior space of the body during a twist-closure operation, and a plunger operably connected to the gear assembly.
