Composite dough container with multiple stacked ingredient cups

A composite container filled with an expandable product and additional ingredients, and comprising:

• a tubular composite container body having first and second open ends;
• a generally rigid separator disk coaxially positioned in the container body so as to divide the container body into a first tubular portion accessible through the first open end and a second tubular portion accessible through the second open end;
• an expandable product substantially filling the first portion of the container body;
• a first end closure sealingly closing the first open end of the container body;
• a plurality of ingredient cups each including a generally tubular side wall having an upper edge defining an open end of the cup and further including a bottom wall which closes the other end of the cup and a membrane for removably engaging the upper edge to close the open end of the cup, the cups being configured to be stackable with the bottom wall of one cup being supported on the upper edge of another cup, each cup being filled with an additional ingredient and being closed by the removable membrane, one of the cups being inserted into the second portion of the container body until the upper edge of the cup engages the separator disk and each of the other cups being inserted upper-edge-first into the container body until the upper edge engages the bottom wall of a previously inserted cup;
• and
• a second end closure sealingly closing the second open end of the container body and engaging the bottom wall of the last-inserted cup;
• whereby pressure generated by expansion of the product in the container is exerted on the separator disk and is transmitted axially from the separator disk through the side walls of the cups to the second end closure such that the cups are not substantially deformed.
