Nested liner assembly for a trash receptacle
View Patent ↗A nested liner assembly is a plurality of plastic trash liners, one inside the other, with tabs allowing liners to be pulled and separated, and which is held to a trash receptacle by a belt. A collar facilitates the assembling of the liners, holding the liners to the trash receptacle, and the orderly removal of the innermost liner from the remainder of the liners. Through a series of holes formed in the collar, trapped air inside the nested liners may be vented so that the assembly itself can be packaged compactly for shipment and storage.
1. A method for making a nested liner assembly, said method comprising the steps of:
providing a collar having a major axis;
forming a plurality of holes formed in said collar;
forming a fold in said collar parallel to said major axis;
attaching said collar to a strong liner, said strong liner having a mouth and wherein said collar extends beyond said mouth of said strong liner;
inverting said strong liner so that said collar forms a trough with said fold in said trough;
placing a first liner onto over said strong liner;
placing a second liner over said first liner so that said first and second liners are nested liners;
tucking said first and second nested liners into said trough of said collar;
attaching said collar to said nested liners; and
inverting said nested liners so that said nested liners are inside said strong liner.
2. The method of claim 1 , further comprising the steps of;
providing a first mandrel; and
placing said strong liner with said collar on said first mandrel.
3. The method of claim 1 , wherein said collar is made by the process comprising the steps of:
providing a central band of material and an outer band of material, said outer band being longer than said central band;
pleating said outer band to have the same length as said central band of material; and
attaching said central band to said outer band.
4. The method of claim 3 , further comprising the steps of:
proving an inner band of material; and
attaching said inner band to said central band to form said collar.
5. The method of claim 1 , further comprising the step of providing a belt for use with said liners on a trash receptacle having a perimeter, said belt dimensioned for fitting on said perimeter of said trash receptacle.
6. The method of claim 5 , further comprising the steps of
forming a belt of material having a circumference larger than a perimeter of a trash receptacle, said belt having an outer surface;
applying a patch of adhesive to said outer surface of said belt; and
applying a release paper over said patch of adhesive.
7. The method of claim 1 , wherein said method further comprises the steps of:
providing a second mandrel wherein said mandrel has holes formed therein in;
drawing air through said holes in said mandrel as said first and said second liner are placed over said second mandrel; and
removing said first and said second liners from said second mandrel before placing said first and second liners on said strong liner.
8. The method of claim 1 , further comprising the step of rolling said nested liners toward said collar to expel any inter-liner air through said plurality of holes of said collar after said inverting step.
9. The method of claim 1 , further comprising the steps of:
placing said first liner on a second mandrel;
drawing air out of said first liner through said second mandrel;
pulling said first liner from said second mandrel to place on said strong liner;
placing said second liner on said second mandrel;
drawing air out of said second liner through said second mandrel; and
pulling said second liner from said second mandrel to place over said first liner on said first mandrel.
10. The method of claim 9 , wherein said collar is made by the process comprising the steps of:
providing a central band of material, an outer band of material, and an inner band of material, said outer band being longer than said central band;
pleating said outer band to have the same length as said central band of material;
attaching said central band to said outer band; and
attaching said inner band to said central band.
11. The method of claim 10 , further comprising the steps of
forming a belt of material having a circumference larger than a perimeter of a trash receptacle, said belt having an outer surface;
applying a patch of adhesive to said outer surface of said belt; and
applying a release paper over said patch of adhesive.
