Abstract:
1. A dispensing and application apparatus wherein the apparatus is designed to contain a flowable substance, comprising: a compartment; at least one sheet divided by at least one seal, joining the at least one sheet to itself or to another of the at least one sheet, to form the compartment, wherein one of the at least one seal is a frangible seal, wherein the frangible seal further includes a stress riser oriented in the direction of the compartment, designed to break when exposed to a predetermined pressure from the flowable substance, internal to the compartment, created by externally pinching the compartment, where the 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 fluid communication between the compartment and an expansible chamber; an applicator having an applicator surface area, a periphery and being joined to the at least one sheet with at least one applicator bond defining a bond area at the interface between the applicator and the at least one sheet and being characterized by a bond surface area; and the expansible chamber being formed by the at least one sheet, and the applicator, and bounded in part by the applicator, the at least one applicator bond, and the frangible seal, such that the expansible chamber absorbs a portion of the kinetic energy of the flowable substance after it breaks through the frangible seal.
