Abstract
A container includes, in one embodiment, an outer housing holding a first mass of a first component of a composition, an inner housing holding a second mass of a second component of the composition, and a seal. The first component is a liquid and the mass of the second component conforms to a bottom and side wall of the inner housing. An interference fit exists between the outer housing and the inner housing such that the inner housing seals the first mass within the first chamber. The inner housing has an aperture in a side wall of the second chamber.
