Abstract:
A container particularly adapted to be selectively changed in axial length comprising a body including a tubular wall, said tubular wall including a plurality of alternating radially outwardly projecting circumferential ribs and radially outwardly opening circumferential valleys defining respective inwardly opening circumferential valleys and inwardly projecting circumferential ribs, at least two substantially axially spaced pairs of inwardly and outwardly projecting ribs defined by a common wall therebetween, at least one inwardly directed circumferential rib and an adjacent outwardly directed circumferential rib being located between said two pairs of ribs, and the exterior diameter of said at least one outwardly directed circumferential rib corresponds substantially to the internal diameter of the inwardly opening circumferential valleys whereby upon the removal of said common wall and a circumferential wall of an adjacent inwardly projecting circumferential rib a band of waste material can be discarded and remaining at least two tubular wall portions of said tubular wall can be telescopically mated with said at least one outwardly directed circumferential rib being seated within and upon a remaining wall portion of one of said inwardly opening circumferential valleys.
