Abstract

A film is provided for use in a cassette. Preferably, the cassette is used in a waste disposal system. The film is a high density polyethylene film resin having both a low melt index and a high density, thereby providing improved odor control capabilities and enhanced tear strength and assembly strength.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A non-resilient flexible tubing for use in a cassette for a disposal system, said tubing being positioned in an annular space of the cassette and adapted to form discrete areas of enclosure of waste, said tubing comprising a high density polyethylene film resin with both a low melt index and a high density.  
     
     
         2 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with a melt index in the range 0.04 g/10 min to 0.50 g/10 min.  
     
     
         3 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with a density in the range 0.90 g/cm 3  to 0.99 g/cm 3 .  
     
     
         4 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with an Elmdorf tear strength in a mold direction in the range 9 g to 20 g.  
     
     
         5 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with an Elmdorf tear strength in a transverse direction in the range 30 g to 400 g.  
     
     
         6 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with a tensile strength at break in a mold direction of 7,000 psi to 13,000 psi.  
     
     
         7 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with a tensile strength at break in a transverse direction of 6,000 psi to 10,000 psi.  
     
     
         8 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with an elongation at break in a mold direction of 250% to 500%.  
     
     
         9 . The tubing of  claim 1 , wherein said film is a high density polyethylene film resin with an elongation at break in a transverse direction of 300% to 700%.  
     
     
         10 . The tubing of  claim 1 , wherein said high density polyethylene film resin is formed into the tubing with a thickness in the range of 7 μm to 30 μm.  
     
     
         11 . The tubing of  claim 1 , wherein the high density polyethylene film resin includes a colorant.  
     
     
         12 . The tubing of  claim 1 , wherein the high density polyethylene film resin includes a deodorant.  
     
     
         13 . The tubing of  claim 1 , wherein the high density polyethylene film resin includes a fragrance.  
     
     
         14 . A cassette for dispensing film in a waste disposal system comprising: 
 a body having a top, said body defining an annular space therein, said body being adapted to rotate in a container of the system,    a length of non-resilient flexible tubing positioned for use in a tight layer in said annular space, said tubing being a film having odor control capability and high tear strength,    wherein said tubing is dispensed through the top of said body when said body rotates to seal said tubing, and    wherein said film is formed of a high density polyethylene film resin with both a low melt index and a high density.    
     
     
         15 . The cassette of  claim 15 , wherein said film has said melt index in the range 0.04 g/10 min to 0.50 g/10 min.  
     
     
         16 . The cassette of  claim 15 , wherein said film has a density in the range 0.90 g/cm 3  to 0.99 g/cm 3 .  
     
     
         17 . The cassette of  claim 15 , wherein said film has an Elmdorf tear strength in a mold direction in the range 9 g to 20 g.  
     
     
         18 . The cassette of  claim 15 , wherein said film has an Elmdorf tear strength in a transverse direction in the range 30 g to 400 g.  
     
     
         19 . The cassette of  claim 15 , wherein said film has a tensile strength at break in a mold direction of 7,000 psi to 13,000 psi.  
     
     
         20 . The cassette of  claim 15 , wherein said film has a tensile strength at break in a transverse direction of 6,000 psi to 10,000 psi.  
     
     
         21 . The cassette of  claim 15 , wherein said film has an elongation at break in a mold direction of 250% to 500%.  
     
     
         22 . The cassette of  claim 15 , wherein said film has an elongation at break in a transverse direction of 300% to 700%.  
     
     
         23 . The cassette of  claim 15 , wherein said film is formed into said tubing with a thickness in the range of 7 μm to 30 μm.  
     
     
         24 . The cassette of  claim 15 , wherein the high density polyethylene film resin includes a colorant.  
     
     
         25 . The cassette of  claim 15 , wherein the high density polyethylene film resin includes a deodorant.  
     
     
         26 . The cassette of  claim 15 , wherein the high density polyethylene film resin includes a fragrance.
