Abstract
Abstract A cartridge comprising a compressed plastic tube for mounting on the tapered end of a hollow cylindrical member into which solid waste or refuse is rammed so that the tube can subsequently be tied and cut into relatively small units containing slugs of compacted refuse. The plastic tube comprises external folds generally about 20 in. in length which extend in the same direction, alternate ones of the folds being separably secured intact or in their folded condition by heat sealing or adhesive means so that after a length of tube, such for example as 33 ft., is filled with compacted refuse, the heat sealing or adhesive means of the alternate folds can be readily pulled open and the thus unfolded folds tied and severed between the ties to form smaller plastic containers of compacted refuse.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
For use with a refuse compaction machine and adapted to be mounted as a cartridge on the delivery end of a hollow cylindrical compaction member; a plastic tube having elongated sections and external folds connecting adjacent sections and extending in the same direction towards one end of said tube, each fold including an outer portion continuous with one section of said tube, an inner portion adjacent to the outer portion of an adjacent section and continuous therewith and a web connecting said inner and outer fold portions, and bonding means separably connecting said inner and outer portions of alternate or every other fold to each other so that said tube is compressible to a relatively short overall length but when said tube is filled with compacted refuse, every other unsealed fold unfolds but the sealed folds remain intact so that a longitudinal force can then be exerted to separate said bonding means and said sealed folds can be thereby also extended, gathered, tied and severed between the ties to form separate small filled container units.
Claim 2
Dependent Claim
175 words
For use with a refuse compaction machine and adapted to be mounted as a cartridge on the delivery end of a hollow cylindrical compaction member; a plastic tube having elongated sections and external folds connecting adjacent sections and extending in the same direction towards one end of said tube, each fold including an outer portion continuous with one section of said tube, an inner portion adjacent to the outer portion of an adjacent section and continuous therewith and a web connecting said inner and outer fold portions, and bonding means separably connecting said inner and outer portions of alternate or every other fold to each other so that said tube is compressible to a relatively short overall length but when said tube is filled with compacted refuse, every other unsealed fold unfolds but the sealed folds remain intact so that a longitudinal force can then be exerted to separate said bonding means and said sealed folds can be thereby also extended, gathered, tied and severed between the ties to form separate small filled container units.
Claim 3
Dependent Claim
30 words
The plastic tube of claim 1 wherein said separable bonding means of said alternate folds includes heat seals at the base of said inner and outer portions opposite said web.
Claim 4
Dependent Claim
26 words
The plastic tube of claim 1 and a weakened circumferentially extending area in either the inner or outer portion of an alternate fold adjacent its web.
Claim 5
Dependent Claim
30 words
The plastic tube of claim 1 wherein said separable bonding means of said alternate folds includes adhesive seals at the base of said inner and outer portions opposite said web.
Claim 6
Dependent Claim
168 words
For use with a refuse compaction machine and adapted to be mounted as a cartridge on the delivery end of a hollow cyclindrical compaction member; a plastic tube having elongated sections and external folds connecting adjacent sections and extending in the same direction towards one end of said tube, each fold including an outer portion continuous with one section of said tube, an inner portion adjacent to the outer portion of an adjacent section and continuous therewith and a web connecting said inner and outer fold portions, and separable adhesive means retaining the webs of alternate or every other fold against the outer portions of adjacent sections so that said alternate adhered folds remain intact when the plastic tube is filled with compacted refuse while the folds without adhesive means unfold, and then a pull can be exerted on the plastic tube to sever the adhesive means whereby the folds are extended and then gathered, tied and severed between the ties to form separate small filled container units.
Claim 7
Dependent Claim
168 words
For use with a refuse compaction machine and adapted to be mounted as a cartridge on the delivery end of a hollow cyclindrical compaction member; a plastic tube having elongated sections and external folds connecting adjacent sections and extending in the same direction towards one end of said tube, each fold including an outer portion continuous with one section of said tube, an inner portion adjacent to the outer portion of an adjacent section and continuous therewith and a web connecting said inner and outer fold portions, and separable adhesive means retaining the webs of alternate or every other fold against the outer portions of adjacent sections so that said alternate adhered folds remain intact when the plastic tube is filled with compacted refuse while the folds without adhesive means unfold, and then a pull can be exerted on the plastic tube to sever the adhesive means whereby the folds are extended and then gathered, tied and severed between the ties to form separate small filled container units.
Claim 8
Dependent Claim
35 words
The plastic tube of claim 5 wherein said separable adhesive means includes circumferentially spaced adhesive strips engaging one section, bridging the web of said alternate fold and engaging the outer portion of the adjacent section.
