Abstract: Method of and apparatus for heating or cooking a food product packaged within a container by using heated air. The oven apparatus includes a substantially closed-loop heated air system that starts with a blower that blows air into a heating barrel where a heating element heats the air to a high temperature. The heated air exits the heating barrel, passes through an air flow channel in the oven's door, and enters the oven's heating chamber. The heated air passes through the container inside the heating chamber and heats the food product within the container. In a preferred embodiment of the invention, the heating chamber is rotated while the heated air passes through the container to tumble the food product and ensure even heating thereof. The air exiting from the food product container enters a recirculation chamber which directs the air back into the blower to repeat the cycle.

Abstract: A container for successively dispensing substantially uniform volumes of a plurality of liquid ingredients such that the liquids are simultaneously dispensed in a desired proportion to form a mixture. The container has a plurality of separate compartments; each compartment being adapted to house a different liquid ingredient. Each compartment has a tubular metering device located therein. The metering device dispenses a previously metered volume and meters a second volume by controlling the venting of air within the compartment each time the container is tilted and uprighted as in a normal dispensing operation. A continuous lip surrounds the dispensing opening of each metering device. The continuous lip prevents a liquid ingredient from entering the dispensing opening of another liquid ingredient compartment and contaminating that compartment. In addition, a flip top cap is attached to the upper end wall. In the closed position the cap seals the dispensing openings of each metering device.
