ABSTRACT:
A clamshell or other hinged top cover type carton for hamburgers is provided with a divider sheet formed from paperboard or a paperboard laminate. The ends of the divider sheet extend laterally beyond the side edges of the carton. A bun heel and hot hamburger patty are located in the lower half of the container and a bun crown and various toppings are located in the top container half. The divider sheet separates the hot meat patty from the cooler toppings. For hamburger consumption, the user pulls a laterally extending edge of the divider sheet laterally away from the carton, the bun crown and toppings fall on to the hot hamburger patty and bun heel, thereby preparing the hamburger sandwich. The consumer now opens the carton to gain access to the sandwich.
