Abstract

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.

Claims

1. A dual container comprising:

an outer container and an inner container, said inner container having a surrounding said partition wall; and

a preformed opening in said partition wall, a sealing seat which forms part of said container, and said seat being placed for normally closing said opening and wherein said sealing seat is removed from said opening so as to form a passageway;

a foil like lid coupled to said partition wall in such a manner that said preformed opening is removed from said sealing seat and said passageway is formed in said partition wall in response to the at least partial removal of said lid from said container, said tops of said containers are both normally coupled to said foil like lid to close each of said containers, and wherein said inner container with said partition wall remains fully coupled to said lid when said lid is at least partially removed from said outer container.

2. The container of claim 1, wherein said sealing seat is formed on a sidewall of said outer container adjacent said preformed opening.

3. A method comprising:

providing a container which includes an outer container and an inner container, the walls of said inner container defining a partition wall separating said outer and said inner containers;

said container including structural components which will form a passageway between said outer and said inner containers in response to a predetermined deformation of the exterior of said outer container;

said partition wall having a preformed opening that is normally closed by a sealing seat which forms part of said container;

said container including a foil like lid which is coupled to said partition wall of said inner container;

said inner and said outer containers are both open at their tops and are both normally coupled to said foil like lid to close each of said containers;

the further step of deforming said exterior of said container in said predetermined manner comprising at least partially removing said lid from said container for causing said structure components to form said passageway between said inner and outer containers by removing said preformed opening from said sealing seat for forming said passageway in said partition wall between said inner and outer containers in response to the at least partial removal of said lid from said container, said inner container remains fully coupled to said lid during said deforming step.

4. The method of claim 3, wherein sealing seat is formed on a side wall of said outer container adjacent said preformed opening.
