ABSTRACT:
A pocket assembly and paperboard blank for forming the same are provided. The blank comprises a front retaining panel, a front support panel, a rear support panel and a rear retaining panel cosecutively articulated to one another along fold lines that are preferably parallel to one another. The front and rear retaining panels each are provided with score lines extending away from their articulations to the respective front and rear support panels. The score lines are formed to define continuous embossments extending from selected surfaces of the front and rear retaining panels. An appropriate adhesive then is applied adjacent the embossments. The pocket assembly is formed by rotating the front and rear retaining panels approximately 180.degree. around their respective articulations to the front and rear support panels such that the embossments defined therein are in substantially continuous contact with the opposing faces of the front and rear support panels. The adhesive areas then are activated to secure controlled and selected portions of the front and rear retaining panels to the front and rear support panels. The continuous embossments positively prevent unintended bleeding or spreading of the adhesive material into the area intended to be the pocket.
