Abstract
A deep compartment tray includes compartments separated by dividers which extend to between one-third and substantially the full depth of the tray. The tray is constructed from sheet material, such as polyester coated paper milk carton stock. The pre-forming step and the forming step for the tray are conducted by a first female die defining the tray cavities or compartments, and surrounded by a first draw pad region, and a second male die including bosses or land areas in the compartment regions and recesses where the tray dividers are to be formed. The male die includes a set of cavities, one in each of the tray compartment regions. The cavities slidably receive plungers or inserts which are movably mounted in the cavities and are spring-urged to their fully projected positions in the cavities. A second draw pad surrounds the male die, and is mounted for resistive movement relative to the male die.
