METHOD OF FORMING COMMUNICATING PORT BETWEEN AT LEAST TWO HOUSING CHAMBER IN ONE VESSEL UNIT AND VESSEL UNIT

摘要

A container is divided into two receiving chambers by a partition wall. Each chamber houses a material, such as yogurt in one and cereal flakes in the other. The container includes structural components which will create an opening in the partition wall in response to a predetermined manipulation of the outside of the container so as to enable the material contained in the two chambers to be combined in a single chamber.
