Abstract
Abstract A container for use with a compacting system includes spring loaded rectractable 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A container for use in compacting systems and the like comprising: a solid bottomed housing for receiving material to be compacted therein, said housing comprising an open top outer container having a releasable peripheral side wall portion, a liner which is adapted to receive a bag member thereover and in which material is to be compacted, said liner shielding said bag member from damage during compaction and comprising a onepiece, flexible, hollow, open-bottomed, tubular-shaped member having walls which, upon releasing of said releasable portion of said outer container after said material is compacted, flex outwardly and release from the compacted material therein; and a plurality of spring supported wheels supporting said housing, the bias force of said springs retaining said housing in a raised position under the weight of a full load of material in said housing and allowing said housing to lower during application of downward forces substantially exceeding the weight of a full load of material in said housing.
Claim 2
Dependent Claim
161 words
A container for use in compacting systems and the like comprising: a solid bottomed housing for receiving material to be compacted therein, said housing comprising an open top outer container having a releasable peripheral side wall portion, a liner which is adapted to receive a bag member thereover and in which material is to be compacted, said liner shielding said bag member from damage during compaction and comprising a onepiece, flexible, hollow, open-bottomed, tubular-shaped member having walls which, upon releasing of said releasable portion of said outer container after said material is compacted, flex outwardly and release from the compacted material therein; and a plurality of spring supported wheels supporting said housing, the bias force of said springs retaining said housing in a raised position under the weight of a full load of material in said housing and allowing said housing to lower during application of downward forces substantially exceeding the weight of a full load of material in said housing.
Claim 3
Dependent Claim
22 words
Apparatus according to claim 1 wherein said releasable portion of said housing includes an openable door portion in the side walls thereof.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 2 wherein said door portion is hingedly mounted to a side wall of the housing.
Claim 5
Dependent Claim
52 words
Apparatus according to claim 1 wherein said compacting system includes a compacting station having support means for supporting said container during compaction, such that upon application of compacting forces, said container is lowered against the bias force of said springs and said support means bears substantially all of said force of compaction.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 4 wherein said support means is located below the lower surface of said container.
Claim 7
Dependent Claim
32 words
Apparatus according to claim 5 wherein said support means is located substantially centrally below said container and supports a substantial portion of the bottom of said container during application of downward forces.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 5 wherein said support means is located at at least two side edges of said bottom of said container.
Claim 9
Dependent Claim
14 words
Apparatus according to claim 1 wherein said liner has a continuous peripheral wall section.
