ABSTRACT:
A ribbed trash container suitable for supporting a collapsible trash liner comprising a hollow body having an open top, a closed bottom, and an interior surface portion provided with a plurality of laterally spaced apart, generally vertical ribs. The ribs define between themselves a plurality of narrow channels that extend longitudinally between the open top and closed bottom. In another embodiment, the ribs and channels are formed in an adaptor piece for assembling with and upgrading a standard trash container. The channels of either embodiment have such narrow laterally dimensioned openings that projections of the liner are generally unable to enter the channels to a degree which would significantly obstruct the passage of air therethrough. The channels provide a passage for the escape of air trapped between the container and liner during filling of the liner; and the channels also provide for the passage of air during the removal of the liner from the container, thereby preventing the formation of a vacuum that would tend to cause the retention of the liner inside the container.
