ABSTRACT:
A device for storing and transporting articles embodies a self-openable carton which comprises, in integral combination, a pair of first sidewalls hingedly connected to each other by a hinge crease, a pair of remote folded sidewalls, each one of which is respectively connected to corresponding ones of the first pair of sidewalls, wherein the remote sidewalls have transversely folded reinforcing end tabs. The carton, as envisioned, comprises first and second interior and diagonally arranged retaining walls. Each of the retaining walls is connected to and folded with respect to corresponding ones of the remote sidewalls. Each of the retaining walls may be formed with at least one article receiving compartment, such that whenever in a locked and assembled position each of the diagonal retaining walls is in opposed relation with respect to the other, and whenever in an unlocked position are enabled to automatically move apart from each other to thereby expose articles received within the compartments. End flaps are folded at opposite ends of the retaining walls with folded locking tab means for slidably cooperating with corresponding ones of the reinforcing end tabs to position and support each of the end flaps and the retaining walls to corresponding ones of the remote sidewalls. Connecting strip means are contemplated which are foldably connected to longitudinal edges of the retaining walls and are directly connected to the interior surfaces of corresponding ones of the first pair of sidewalls longitudinally adjacent the hinge crease. Such device comprises locking means operatively cooperating with the self-openable carton which enables the carton to be easily locked and unlocked. Also envisaged is a blank of material which comprises a construction that permits formation of the self-openable carton.
