Refill Film for Waste Disposal Apparatus, Refill Film Accommodating Cassette, and Portable Waste Disposal Bag

Abstract

A refill film for a waste disposal apparatus includes: a film annular body that is formed by a long tubular film folded so as to be compressed in an extending direction thereof; and a wrapping sheet that is made of a material capable of being cut, and wraps the film annular body while keeping a central hole of the film annular body open, and maintains the compressed state. Such a refill film is directly placed in a waste inlet of the waste disposal apparatus.

What is claimed is: 
     
         1 . A refill film for a waste disposal apparatus, which is attached to said waste disposal apparatus for containing a waste material in a tubular film and disposing of said waste material, comprising:
 a film annular body that is formed by a long tubular film folded so as to be compressed in an extending direction thereof; and   a wrapping material that is made of a material capable of being cut, and wraps said film annular body while keeping a central hole of said film annular body open, and maintains said compressed state.   
     
     
         2 . The refill film according to  claim 1 , wherein
 said wrapping material has a cut line for tearing off said wrapping material.   
     
     
         3 . The refill film according to  claim 1 , wherein
 said wrapping material covers an outer peripheral surface, one axial end, and the other axial end of said film annular body, and exposes an inner peripheral surface of said film annular body.   
     
     
         4 . The refill film according to  claims 1 , wherein
 said wrapping material is made of paper, a fiber material, or a resin film.   
     
     
         5 . The refill film according to  claim 1 , wherein
 said wrapping material is a plurality of bands that are wound around said film annular body at predetermined intervals in a circumferential direction.   
     
     
         6 . A refill film accommodating cassette that is attached to a waste disposal apparatus for containing a waste material in a tubular film to dispose of said waste material, and accommodates said refill film according to  claims 1 , comprising:
 a cylindrical portion that is inserted in said central hole of said film annular body; and   an outward flange that is formed at one axial end of said cylindrical portion to prevent said film annular body from coming off from said refill film accommodating cassette.   
     
     
         7 . The refill film accommodating cassette according to  claim 6 , further comprising:
 an annular holding member that is detachably coupled to the other axial end of said cylindrical portion to prevent said film annular body from coming off from said refill film accommodating cassette, wherein   said tubular film that is pulled out from said film annular body is inserted through said central hole of said cylindrical portion beyond said holding member.   
     
     
         8 . A portable waste disposal bag, comprising a tubular body which is made of a bendable material, wherein
 said tubular body surrounds an outer periphery of said refill film accommodating cassette according to  claim 6 , and an outer surface of said tubular film that is pulled out from said refill film accommodating cassette and passes through a central hole of said film accommodating cassette,   one longitudinal end and the other longitudinal end of said tubular body are capable of being opened and closed,   said refill film accommodating cassette is detachably attached to said one longitudinal end, and   said tubular body is long enough that the other longitudinal end can be twisted by 360° or more with respect to said one longitudinal end.   
     
     
         9 . The portable waste disposal bag according to  claim 8 , further comprising:
 a fastening device for restricting the length of said tubular body.
