Abstract
A container for prepackaging materials, as for example silver alloy and mercury for dental amalgam, which must be kept separate until just prior to combination and use is disclosed which comprises two chambers. During storage of the materials, the two chambers are separated by a barrier to prevent mixing of the ingredients therein. Combination of the ingredients is effected by twisting the top portion of the container to align a conduit therein with an opening in the barrier between the two chambers. After the material in the upper chamber flows into the lower chamber, the top portion is twisted back to close off the opening and the materials are mixed together by agitating the container.
