Abstract
Abstract A package assembly includes a plurality of side-by-side similar open ended tubular articles, the openings at each end being closed by a common end member formed of a unitary blank. Each end member includes tongues projecting into respective articles, each tongue including superimposed similar panels joined at their outer edges along a fold line and having outwardly converging outer side edges and parallel inner side edges transversely spaced from the inner side edges of adjacent tongue panels. Coplanar wing panels project oppositely from the inner edges of corresponding sets of side-by-side tongue panels. In assembled condition the tongues retain the tubular articles in side-by-side positions and the wings close the receptacle end openings to facilitate the wrapping and display of the articles.
