Abstract
A clamshell style paper board container including a tab-and-slot closure to openably secured the top and bottom halves of the clamshell in a closed position. Unlike conventional designs where the tabs in the bottom half extend from the side walls toward the front of the container, the tabs in the bottom half extend from the front wall toward the sides of the container. Also, a punch in device that can be used to provide a steam hole and/or an indicator of package contents where the punch in device include four generally parallel fold lines extending between two generally parallel perforations. When the punch-in device is punched in by a user, one of the fold lines is moved from: (i) a folded state at a location at a corner between two walls of the container to; (ii) an unfolded state at a location displaced from the corned toward the interior of the container.
