发明名称 Wrapper or sleeve type package with pocket and flap lock
摘要 A wrapper or sleeve type package of paperboard or the like for providing a laterally encompassing wrap package for articles, formed from an elongated blank of paperboard material to provide a bottom panel and a pair of opposite side panels integrally joined thereto to extend upwardly from the bottom panel in laterally encompassing relation to the article to be contained therein. At the uppermost edges of the side panels are a pocket panel joined along a fold line to the uppermost edge of one of the side panels and folded on itself to define a downwardly opening pocket and a tuck flap panel is joined to the other side panel and folded upon itself to define a tuck flap to be inserted into the pocket. Abutment edge portions on the folded tuck flap confront intercept edge portions within the pocket when the tuck flap is fully inserted into the pocket to restrain the folded tuck flap against withdrawal from the pocket.
