Abstract

A fully enclosed pack is provided with a gusset that is capable of being formed from a blank without the use of tucker fingers. Nicks are provided between the side end panel and tuck-in panels of the carton. As the side end panels are folded, the nicks help pull the tuck-in panels inwardly to allow the gusset of the carton to take form without the use of tucker fingers in a folding/gluing operation.
