Abstract: A container for carrying produce having dove tail locks is created from a container blank having nonsymmetrical, offset dove tail locks on the edges of the blank. When the blank is on a larger paperboard substrate having multiple blanks, the dove tail locks of a blank border the dove tail locks of an adjacent blank in a configuration that eliminates pinch points. The elimination of pinch points is achieved by having dove tail locks wherein the sides of the dove tail lock diverge from each other at different angles and for different horizontal vectors.

Abstract: A disposable container is made from an integral blank of corrugated cardboard for folding between a relatively flat configuration for storage and a set-up configuration for receiving articles. A bottom wall is foldably attached to two pairs of side walls. The side walls are joined by four pleated walls to form a seamless interior portion when the walls are raised into a set-up configuration perpendicular to the bottom wall. The side and pleated walls include user-friendly self-locking elements for securing the set-up configuration. A moisture barrier coating on the interior permits ice and perishables to be received in the seamless interior portion to provide a disposable insulated cooler. A pair of folding top walls provide handles. One of the top walls includes a locking panel with lateral locking tabs which fold down across the top of the set-up cooler so that the closure locking tabs are seated in respective planar slots formed by the raised walls for positively closing the cooler interior.
