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.
