Abstract
A two-compartment container in which the first compartment has an upper layer and a lower layer and contains a first component that is to be added to the second compartment. Above the first compartment is a dome that is bowed upward and is flexible. Depressing the dome by pushing downward on it causes the lower layer of the first compartment to be ruptured without cutting or rupturing the upper layer, releasing the first component into the second compartment.
