Cassette and apparatus for packing disposable objects into an elongated tube of flexible material
A cassette for dispensing bags from an elongated tubing comprising an annular receptacle accommodating a length of tubing in an accumulated condition. An annular opening at an upper end of the annular receptacle is for dispensing the tubing. The annular receptacle defines a central opening through which a knotted end of the tubing passes to form a bag supported by the annular receptacle with disposable objects passing through the circular central opening to be received in the bag, and a clearance only at a bottom of the central opening.
1. A method for disposing of objects in a pail of a waste disposal system having a film-dispensing cassette, the film-dispensing cassette including an annular receptacle defining a central opening, the annular receptacle including a volume receiving an elongated tube of flexible material radially outward of the central opening, the method comprising:
orienting the annular receptacle so as to have a bottom of the annular receptacle facing a cassette holder located in an upper portion of the pail;
seating a portion of the annular receptacle of the film-dispensing cassette in the cassette holder against an interfering member of the cassette holder having an oblique cassette-orienting wall supporting the annular receptacle, with part of the elongated tube of flexible material passing through the central opening of the annular receptacle and extending into an enclosure of the pail; and
disposing waste into the elongated tube of flexible material that extends into the enclosure of the pail through the central opening of the annular receptacle.
2. The method of claim 1 , comprising, folding the elongated tube of flexible material over an upper flange attached to the annular receptacle to pass the part of the elongated tube of flexible material through the central opening of the annular receptacle.
3. The method of claim 1 , further comprising opening a lid of the pail to gain access to the cassette holder.
4. The method of claim 1 , further comprising aligning the central opening of the annular receptacle with an opening of the cassette holder.
5. The method of claim 1 , further comprising forming a bag end by knotting a free end of the elongated tube of flexible material.
6. The method of claim 1 , comprising further withdrawing the elongated tube of flexible material from the volume of the annular receptacle.
7. The method of claim 1 , further comprising cutting the elongated tube of flexible material, and forming a substantially sealed pouch by tying a cut end of the elongated tube of flexible material.
8. The method of claim 7 , further comprising removing the substantially sealed pouch from the pail.
9. A method for installing a film-dispensing cassette in a pail of a waste disposal system, the film-dispensing cassette including an annular receptacle defining a central opening, the annular receptacle including a volume receiving an elongated tube of flexible material radially outward of the central opening, the method comprising:
withdrawing a length of the elongated tube of flexible material from the volume of the annular receptacle, the length of the elongated tube of flexible material including a free end of the elongated tube of flexible material;
passing the free end through the central opening of the annular receptacle; and
seating the annular receptacle against an interfering member of a cassette holder in an upper portion of the pail, the interfering member having an oblique cassette-orienting wall supporting the annular receptacle and engaging an edge of the annular receptacle, the edge delimiting a lower surface of the annular receptacle.
10. The method of claim 9 , wherein the withdrawing of the length of the elongated tube of flexible material from the volume of the annular receptacle includes pulling on the free end of the elongated tube of flexible material out from an upper annular opening of the annular receptacle, the upper annular opening defined atop the volume of the annular receptacle.
11. The method of claim 9 , wherein the withdrawing of the length of the elongated tube of flexible material from the volume of the annular receptacle includes pulling the free end of the elongated tube of flexible material into an enclosure of the pail.
12. The method of claim 9 , further comprising forming a bag end by knotting the free end of the elongated tube of flexible material.
13. The method of claim 12 , wherein the forming of the bag end is achieved prior to the passing of the free end of the elongated tube of flexible material in the central opening of the annular receptacle.
14. The method of claim 9 , further comprising aligning the central opening of the annular receptacle with an opening in the upper portion of the pail.
15. The method of claim 9 , further comprising opening a lid of the pail to gain access to the cassette holder.
16. The method of claim 9 , comprising, folding the length of the elongated tube of flexible material over an upper flange attached to the annular receptacle by the passing of the free end of the elongated tube of flexible material through the central opening of the annular receptacle.
17. The method of claim 9 , wherein the seating of the annular receptacle includes abutting an oblique wall of the annular receptacle against the interfering member.
18. The method of claim 9 , wherein the withdrawing of the length of the elongated tube of flexible material from the volume of the annular receptacle is achieved prior to the passing of the free end of the elongated tube of flexible material through the central opening, the passing of the free end being achieved prior to the seating of the annular receptacle against the interfering member of the cassette holder of the pail.
