Abstract:
1. An improved material packaging system, comprising: (a) a plurality of nested liners removably attached to each other to form a unitary liner structure, each of said nested liners having a bottom portion inwardly folded for preventing engagement of said bottom portion with a bottom portion of an adjacent one of said nested liners; (b) a receptacle having a circumferential attachment lip for detachably securing said unitary liner structure to said receptacle; (c) said unitary liner structure having an elastic attachment device for detachably securing said unitary liner structure to said receptacle by expanding said elastic attachment device circumferentially, fitting said elastic attachment device over said attachment lip into a position below said attachment lip, and releasing said elastic attachment device to permit said elastic attachment device to compressibly mate with said receptacle below said attachment lip; (d) each of said liners having a pull grip for gripping said liner to remove said liner from said unitary liner structure and perforations disposed between said pull grip and said elastic attachment device for tearing said liner when a tearing force is applied thereto; and (e) whereby an uppermost liner of said plurality of liners can be removed from said unitary liner structure without substantially disturbing the positioning of underlying liners by gripping and pulling said pull grip of said uppermost liner to apply said tearing force to said perforations of said uppermost liner.
