ABSTRACT:
A carton comprising a pair of space-defining members with confronting closing edges which lock by means of a tab latch. The latch includes a tab which extends from one of the closing edges to pass through a loop formed on a wall adjacent the opposite closing edge. The tab includes a terminal portion which extends through the loop and which has a rear surface that conforms to the wall region rearwardly adjacent the loop. The tab also includes a protuberance on its front, outer surface which is insertable through the loop by deformation of the loop and which is retained thereby. In particular embodiments, the carton is integrally formed in one piece of expanded plastic material with sections of the closing edges hinge-connected. In a specific configuration, the walls of the space defining members taper inwardly from the closing edges so that the tab forms an acute angle with the closing edge from which it extends.
