Claim:
A two-compartment container, for addition of a first component to a second component, comprising: (a) a first compartment having an intact upper layer and a lower layer, the upper layer comprising a plastic laminated aluminum foil and the lower layer comprising aluminum foil with a lacquered surface on the inside of the first compartment, said first compartment containing a first desiccated powdered component that is sensitive to moisture, said upper layer of the first compartment being upwardly bowed, and said lower layer of the first compartment being flat and thinner than the upper layer and easily rupturable without using a puncturing structure; and (b) a second compartment containing a second liquid component, said second compartment comprising a bottle having a cap containing a flexible dome; wherein the first compartment is located inside the cap and beneath the flexible dome, and wherein depression of said flexible dome of the cap causes the intact upper layer of the first compartment to be pushed against the lower layer of the first compartment and the lower layer to be ruptured without using a puncturing structure and without rupturing the upper layer, releasing the first desiccated powdered component into the second compartment without opening either compartment outside the container.
