Abstract
An improvement is provided for a pizza-style paperboard container. The improvement includes first and second separation lines extending through first and second lateral panels, respectively. An additional fold line is provided in the first lateral panel at a location rearward of the first separation line, the material therebetween defining a closure flap. The first lateral panel includes opposed side panels. These side panels include a pre-formed hinge. The second lateral panel also includes opposed side panels. As assembled, the side panels of the first lateral panel are exterior to the side panels of the second lateral panel. After the carton is first assembled in a conventional manner, it may be reduced in size by breaking the carton in two along the separation lines. The closure flap is then pushed inward while the hinges of the outer side panels capture the inner side panels.
