Sanitary containers

A method of use of a cassette for a sanitary container, said sanitary container having a housing with a hollow interior and an upper aperture, with a portion of said housing able to open and reveal at least in part, said hollow interior, said method comprising:

• a) accessing, when said portion is open, an internally non-rotationally mounted cassette having a central aperture within said hollow interior of said container, said cassette to hold a length of plastics tubing in a shirred state, the cassette further having an endless exit aperture at an uppermost periphery of and immediately adjacent to said central aperture, whereby said shirred plastics tubing can leave said cassette upwardly via said endless exit aperture, and then flow down through the central aperture to form a containment,
• b) if said cassette is not empty, then
• i. drawing downward an existing containment substantially within a hollow interior of said container to form a new containment replenished from said central aperture of said cassette,
• ii. sealing said new containment at a lower end thereof to close said lower end, and
• iii. severing said existing containment from said new containment, to thereby allow removal of said existing containment and any waste therein from said container, or
• c) if said cassette is empty, or nearly empty, then,
• i. releasing said cassette from said hollow interior in a downward direction and removing said cassette and any existing containment present,
• ii. installing a new cassette into said hollow interior in an upwardly direction,
• iii. drawing a new containment downwardly if necessary, and if not sealed at a lower end, then sealing said new containment,
• to thereby provide a refreshed containment, and then closing the portion to close the hollow interior.
