Multiple compartment storage and dispensing apparatus

A dispensing and application apparatus wherein the apparatus is designed to contain a flowable substance, comprising:

• at least two compartments;
• a first sheet section and a second sheet section interconnected with a primary seal and at least two frangible seals to form said compartments, the frangible seals further including stress risers oriented in the direction of the compartments and being designed to break when exposed to a predetermined pressure internal to the compartments, created by externally pinching the compartments, where the frangible seals peel apart in such a manner that no portion of the frangible seals separates from the at least one sheet and becomes entrained in the flowable substance, thereby creating a channel permitting fluid communication between the compartments and an expansible chamber;
• an applicator having a periphery and being joined to the first sheet section and the second sheet section with at least one applicator bond;
• and
• the expansible chamber being formed by the first sheet section, the second sheet section, and the applicator, and bounded in part by the applicator, the applicator bond, and one frangible seal.

A dispensing, mixing, and application apparatus wherein the apparatus is designed to separately contain a plurality of substances, comprising:

• at least one sheet divided by a plurality of frangible seals to form a plurality of compartments including a first compartment housing a first substance and a second compartment housing a second substance;
• a first frangible seal located at an intermediate edge between the first compartment and the second compartment, further including a first stress riser oriented in the direction of the first compartment and designed to break when exposed to a first predetermined pressure, internal to the compartment, created by externally pinching the first compartment, where the first frangible seal peels apart in such a manner that no portion of the frangible seal separates from the at least one sheet and becomes entrained in the flowable substance, less than or equal to a second predetermined pressure, thereby creating a channel permitting communication between the first compartment and the second compartment permitting mixing of the first and second substances;
• a second frangible seal located at a common edge between the second compartment and a chamber, further including a second stress riser oriented in the direction of the second compartment and designed to break when exposed to a second predetermined pressure internal to the compartment, created by externally pinching the second compartment, where the second frangible seal peels apart in such a manner that no portion of the frangible seal separates from the at least one sheet and becomes entrained in the flowable substance, thereby creating a channel permitting communication between the second compartment and an expansible chamber;
• and
• the expansible chamber being formed by the at least one sheet such that the expansible chamber absorbs a portion of the kinetic energy of the flowable substance after it breaks through the second frangible seal, and dispensing a mixture of at least the first and second substances.
