Abstract

Abstract A rigid container having a bottom and walls and a peripherally depending rigid skirt for offsetting the bottom of the container from a support surface. The skirt has one or more spaced orifices and affixed to the underside of the bottom of the container is a ratchet bar. A pawl including, a pawl escapement tooth, a pawl arm and a vertical member extending at right angles to the pawl arm, is located through the orifice of the skirt so as to be in slideable engagement with the ratchet bar. This arrangement is adapted to receive a supply package of liner bags located between the upright member and the wall of the container. The supply package is of sufficient resiliency so as to permit locking engagement of the package between the upright member and the container.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 190 words
The combination comprising a rigid container having a bottom planar surface and a wall member, at least one rachet bar fixed in association with said planar surface, at least one pawl including a pawl escapement tooth and a pawl arm in association therewith; said container having a peripherally depending rigid skirt for offsetting the bottom of said container from a support surface, at least one orifice in said skirt functioning as a fulcrum for said pawl arm located so as to permit said pawl tooth to move into and out of engagement with the teeth of said rachet bar; an upright member fixed at the end of said pawl arm opposite to said pawl tooth and extending in the same direction as said pawl tooth, said pawl tooth and arm being slideable in relation to said rachet bar, fulcrum and wall member; said combination being adapted to receive a package, which is decreasible in size, between said upright member and said wall member, said upright member being structured so as to exert a spring-force against said package when said pawl escapement tooth is in locked engagement with said rachet bar.
Claim 2
Dependent Claim 190 words
The combination comprising a rigid container having a bottom planar surface and a wall member, at least one rachet bar fixed in association with said planar surface, at least one pawl including a pawl escapement tooth and a pawl arm in association therewith; said container having a peripherally depending rigid skirt for offsetting the bottom of said container from a support surface, at least one orifice in said skirt functioning as a fulcrum for said pawl arm located so as to permit said pawl tooth to move into and out of engagement with the teeth of said rachet bar; an upright member fixed at the end of said pawl arm opposite to said pawl tooth and extending in the same direction as said pawl tooth, said pawl tooth and arm being slideable in relation to said rachet bar, fulcrum and wall member; said combination being adapted to receive a package, which is decreasible in size, between said upright member and said wall member, said upright member being structured so as to exert a spring-force against said package when said pawl escapement tooth is in locked engagement with said rachet bar.
Claim 3
Dependent Claim 33 words
The combination of claim 1 including a pair of spaced, parallel ratchet bars, a pair of said pawls, a pair of said orifices and a pair of inwardly curved or angled upright members.
