A dispensing container having an annular side wall and a lower end wall closing a lower end of the side wall. The lower end wall is provided with a discharge opening which is spaced a selected distance from a center of the lower end wall. The lower end wall is spaced upwardly from a lower edge of the side wall to form a circular space inside a lower end portion of the side wall. A circular support plate of a dispensing machine is received in the space, and the opening in the lower end wall is keyed to an opening in the support plate by complementary frusto-conic wall sections at the openings so that only a container which keys to the support plate can be used with the dispensing machine.
