Abstract
A container for a composition made of multiple components includes an outer housing having a chamber and an inner housing having a compartment. The inner housing includes a frangible wall portion that, when ruptured, enables the components to contact each other for mixing. Advantageously, the inner housing can be manufactured separately from the outer housing, and the housings can be assembled during a subsequent operation. In certain embodiments, the inner housing is slidable relative to the outer housing from a first position to a second position, and during the sliding movement a puncturing tool located within the container breaks the frangible wall portion and causes the components to contact each other.
