Abstract

An upper end of a carton includes first and second panels that are in an overlapping relationship with respect to one another. The first panel includes an opening for being in communication with the carton'"'"'s interior. A flexible, elongate closure tab extends through a slot so that the closure tab is interposed between the first and second panels. The closure tab can be slid between the first and second panels, between open and closed configurations. In the closed configuration, the closure tab at least substantially obstructs the opening. In the open configuration, the opening is not substantially obstructed by the closure tab. A projection is engaged by the closure tab for discouraging the closure tab from being completely pulled out of the slot during the open configuration.
