<p>This invention relates to a fully enclosed packaging case (c) for packaging a group of articles such as bottles. The case comprises a sleeve (10) formed from paperboard or similar sheet material and which includes end closure panels (20, 22, 28, 30, 32) at each of its ends, the sleeve being adapted for tightening about the goup of articles, the tightening being accomplished by providing a gusset panel (46) in the top wall (12) of the sleeve. The gusset panel is folded downwardly and secured in overlapping relationship with the underside of an adjacent part of the top wall during the packaging operation so as to reduce the circimference of the sleeve. As a result a three-ply strip of material is provided by two adjacent portions of the top wall with the gusset panel disposed therebetween so providing a strong handle area for the package.</p> |
