ABSTRACT:
A reinforced display carton is cut from a single sheet of material and folded to form exterior wall panels, bottom flaps and an internal subdividing web, that can be collapsed flat for shipping. The bottom flaps lock together when the carton is erected into a rectilinear state, and engage with the subdividing web, which is reinforced by folded over panels. A barb shaped slotted tongue on one of the bottom flaps fits into a slot between the other bottom flaps to lock them, and straddles a lower edge of the internal web. The subdividing web is formed from an extension of a half-width rear panel folded at a rear glue joint with a second half-width rear panel, and is attached at a glue tab to the back side of the front panel. The web has upper and lower reinforcing panels folded up and down over one another and locked in the slot of the tongue. Access openings extend up to the top edge of the front wall on either side of the central web, and the central web reinforces the carton against vertical forces, e.g., due to stacking. The access openings can be closed by top flaps that fold over in a U-shaped configuration and are removable for use of the carton as a dispensing display.
