  • Patent number: 7147880
    Abstract: An improved unitary container having separate compartments which may be used to store two materials, such as milk and cereal. The container is provided with a mid-portion having compressible side walls and a bisecting wall member which separates the compartments and contents and allows the contents of each to be mixed when so desired by the combination of a pull tab/bladder configuration for the milk and hand pressure, the container having a removable lid in the cereal portion of the package allowing access to the cereal and milk for consumption.

  • Patent number: 5514394
    Abstract: A packaging assembly allows two substances, such as cereal and milk, to be held in separate compartments and then mixed when desired by applying hand pressure to the packaging assembly. The packaging assembly is provided with a compressible side wall portion and an impervious membrane having a frangible portion. The membrane separates the compartments such that applied pressure on the top of the package compresses the side wall portion and the downward pressure of the substance in the upper compartment causes the frangible portion of the membrane to rupture and thus allow the two substances to mix together. A partial wall may also be employed adjacent to the membrane to prevent regurgitation of the cereal and milk back into the upper compartment upon mixture in the lower compartment. The lower compartment may be opened to allow consumption directly from the package.
