  • This invention relates to a cassette for a waste storage container, for example for storing waste such as used nappies or diapers.

  • the cassette is particularly adapted for use in waste storage containers for storing waste items such as babies' nappies (or diapers), or other personal waste matter.

  • the inner wall defines a central core.
  • a flange engages with an upper part of the inner wall.
  • the flange extends outwardly, substantially perpendicular to the inner wall.
  • the flange terminates in a circumferential outer edge located inward of an upper edge of the outer wall, so as to form a peripheral gap between the outer wall and the flange.
  • a profusely circumferentially pleated length of flexible tubular film is located in the cavity of the cassette.
  • the flange partially obscures the tubular film within the cavity.
  • a peripheral gap is provided between the outer edge of the flange and the outer wall, through which the tubular film may be drawn in use.
  • a user When the cassette is to be used in conjunction with a waste storage container, a user begins by pulling the top of the tubular film out through the peripheral gap, so that the tubular film extends upwards of the outer edge of the flange. The user then ties the end of the tubular film into a knot, and passes the knotted end down through the central core of the cassette. This knotted end forms the bottom of a waste package into which a used nappy or other waste item can be placed, through the central core of the cassette.
  • the tubular film above the waste item may be twisted, sealing the waste item therein.
  • a series of waste items may be separately sealed within the tubular film, and stored in the waste storage container.

  • the projecting section tapers continuously downwards, from the top of the inner portion, to the outer edge.
  • flexible tubular film can flow more easily over the surface of the flange.
  • the lower outside edge of the outwardly projecting section, and the continuous downward slope of the projecting section, give less resistance to film flow than existing cassettes in which the flange extends substantially perpendicular to the cassette walls.
  • the annular flange further comprises a plurality of strengthening ribs on the underside of the outwardly projecting section.
  • These ribs support the flange and increase its rigidity. Because the projecting section extends downwardly, having an outer edge below the upper edge of the outer wall of the cassette, the strengthening ribs can be deeper and thereby stronger and more supportive. This also enables the ribs to guide the tubular film through the peripheral gap, and away from the corner between the underside of the outwardly extending portion of the flange and the inner wall of the cassette. This helps to ensure that tubular film does not get trapped in this corner, and should lead to fewer rejects during manufacture.
  • the top of the annular flange, and/or the outer edge of the projecting section of the flange are rounded. This assists in smooth flow of tubular film over the flange, into the core of the cassette.

  • a sufficient length of tubular film 125 should be pulled upwards from the peripheral gap 116 so that the user may gather the top edge of the tubular film 125 together above the central core 108 of the cassette 100, and tie the tubular film into a knot.
  • the user then passes the knotted end of the tubular film 125 down through the central core 108 of the cassette, towards the bottom of the waste storage container.
  • the knotted end of flexible tubular film 125 may form the bottom of a waste package into which a used nappy or other waste item can be placed. Once a waste item has been placed in the waste package, the tubular film 125 above the waste item may then be twisted or knotted, sealing the waste item therein. The waste package may then be pushed or otherwise directed through the central core 108 of the cassette, into the waste storage container. During this process, the tubular film 125 flows over the flange 110, over the circumferential rim 117 and into the cassette core 108.
