Abstract
A nestable container which is constructed so that when formed into a stack the ribs formed in the outer surface of one container rest on an inner shoulder of the container below it in the stack, the angle of inclination of the ribs being the same as the angle of inclination of the inner surface of the side wall portion which it abuts of the container below it in the stack, and the outer surface of one container adjacent to the base engaging the inner surface of the side wall portion of the container below it in the stack to form a powder seal. The cups when nested together to form a stack are freely rotatable one inside the other.
