ABSTRACT:
An expandable carton and a blank for forming same has top and bottom panels which are coupled by a self-locking expanding arrangement along three respective side edges of the top and bottom panels. At the fourth side edges of the top and bottom panels, closure flaps are hingedly coupled to close and lock the carton in its expanded or assembled configuration. This permits the carton to be shipped and stored in essentially flat, collapsed configuration, and then easily assembled and closed by simple manual operations without gluing. The carton may be opened by a tear strip arrangement to gain access to the carton interior.
