Abstract
Abstract A container for use with a compacting system includes spring loaded retractable wheel mechanism on the bottom thereof to facilitate handling of the container. The wheels are automatically retracted during the compaction operation due to the pressure of compaction. A liner to enable disposable bags to be more expeditiously used is preferably square in shape and is fabricated of plastic material or the like. Located between the liner and an outer container is a disposable bag. After compaction is complete a portion of the container is swung open and the liner deforms due to residual compression force in the compacted material. This releases the compacted material from the liner and enables the liner to be easily lifted out, the result being that the compacted material remains in the disposable bag, the liner having protected the bag during compaction.

Total Claims: 14
Claim 1
Independent Claim
122 words
Compacting apparatus for use in a compacting system comprising: an open top outer container having an openable peripheral side wall portion; a bag member inserted in said outer container; and a liner which is adapted to be removably inserted in said bag member and in which material is to be compacted, said liner shielding said bag member from damage during compaction and comprising a one-piece, flexible, hollow, open-bottomed, tubular-shaped member having walls which, upon opening of said openable portion of said outer container after said material is compacted, flex outwardly and release from the compacted material therein; said bag being of sufficient size so as not to bind on said outwardly flexed liner during removal of said liner from said bag member.
