Abstract
The present invention is directed to a nestable, food carton formed from a unitary blank of foldable paperboard that converts into a two-compartment serving tray for products such as sandwiches, hamburgers, and the like. It comprises a bottom tray, a top cover, and means connecting the bottom tray to the top cover. The bottom tray comprises a base wall; a front wall, a rear wall, and a pair of side walls, each hingedly connected to, and extending from, the base wall. The top cover is dome-shaped and comprises a top wall; a front wall, a rear wall, and a pair of side walls, each hingedly connected to, and extending from, the top wall. The connecting means comprises a panel hingedly connected to the outer edge of the rear wall of the bottom tray and to the outer edge of the rear wall of the top cover. The connecting means is adapted to permit the top cover to substantially overlie, fully cover, and extend to the base wall of the bottom tray when the carton is closed, and to permit the base wall of the bottom tray and the top wall of the top cover to lie in the same horizontal plane when the carton is open, thereby forming two food serving compartments.
