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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A package assembly including a plurality of transversely spaced longitudinally extending, parallel substantially coextensiveopen ended elongated tubular articles and an end member located at each end of and engaging said tubular articles and characterized in that at least one of said end members is formed of a unitary blank and comprises a plurality of transversal spaced longitudinally extending tongues projecting into respective articles and engaging the inside faces thereof and each including superimposed first and second panels integrally joined along a fold line at their outer edges and a pair of oppositely directed wing panels joined at their inner edges along fold lines to the inner edges of said first and second wing panels respectively, said wing panels engaging and substantially closing the corresponding ends of said articles.
Claim 2
Dependent Claim
128 words
A package assembly including a plurality of transversely spaced longitudinally extending, parallel substantially coextensiveopen ended elongated tubular articles and an end member located at each end of and engaging said tubular articles and characterized in that at least one of said end members is formed of a unitary blank and comprises a plurality of transversal spaced longitudinally extending tongues projecting into respective articles and engaging the inside faces thereof and each including superimposed first and second panels integrally joined along a fold line at their outer edges and a pair of oppositely directed wing panels joined at their inner edges along fold lines to the inner edges of said first and second wing panels respectively, said wing panels engaging and substantially closing the corresponding ends of said articles.
