<p>A dispensing and application apparatus designed to contain pre-measured amounts of a flowable substance. The apparatus comprises a compartment (130) for storing the substance that is partially enclosed by a frangible seal (210), an applicator (100), and an expandable chamber (170) designed to accept and dissipate the hydraulic force created when pressure is applied to the compartment (130), rupturing the frangible seal (210), and expelling the substance into the chamber (170). The applicator (100) is attached to the chamber (170) with an applicator bond area (180). The expandability of the chamber (170) is conferred by expandability of the applicator (100), and is varied in different embodiments by altering the ratio between the area of the applicator bond area (180) and the area of the applicator (100). The frangible seal (210), in one of many embodiments, may be a chevron shape stress riser (250) with a point of inflection (240) oriented towards the compartment (130). A removable cap may cover the applicator.</p> |
