A film-supporting device is used with a waste-disposal unit. The device comprises an annular body. The annular body has an annular wall. The inward radial surface of the wall defines a central opening of the body. The outline of the central opening in a transverse plane of the device has variable diametrical dimensions with a first diameter of greater dimension than the second diameter. The outline has two of the first diameter of generally equal dimension and two of the second diameter of generally equal dimension. The device has tubular film about an outward radial surface of the annular body. A free annular end is dispensed outwardly from the annular wall. The free annular end is closed to form a bag. The opening of the bag is accessible through the central opening and is of optimized shape via the central opening for the disposal of waste. A method for disposing of waste on a scooping tool is also provided.
The film-supporting device according to claim 1, wherein an outer periphery of the annular body as defined by the outer annular wall has an outline geometrically similar to the outline of the central opening.
The film-supporting device according to claim 1, further comprising a cover wall projecting radially outwardly from the inner annular wall.
The film-supporting device according to claim 1, further comprising a flange on the outer annular wall, with an undersurface of the flange defining a shoulder for seating the film-supporting device.
The film-supporting device according to claim 1, wherein the outline of the central opening is a super-ellipse.
The film-supporting device according to claim 1, further comprising a clearance defined by a portion of the inner annular wall extending obliquely upward from a junction with the bottom horizontal wall, said portion of the inner annular wall joining with an upright portion of the inner annular wall whereby the clearance opens into the central opening.
A method of installing a film-dispensing cassette in a bin, the film-dispensing cassette including an annular body, an outer periphery having four corners and a central opening from a bottom to a top of the annular body, the annular body receiving in a volume thereof a tubular film in an accumulated condition radially outward of the central opening, the method comprising:
