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.

A container for prepackaging materials which must be kept separate until just prior to use comprising: a. a generally cylindrical first portion having an open top end and a closed bottom end defining a chamber; b. a generally cylindrical second portion having an open top end, an open bottom end, an inner surface and valve means intermediate said ends, said second portion having its bottom end secured to the top end of said first portion; c. a third portion having a chamber therein and one end rotatably connected with the top end of said second portion, said third portion having valve closing means whereby said valve means on said second portion may be temporarily closed and the chambers in said first portion and said third portion temporarily separated from one another; d. air venting means whereby air may be vented from the chamber in said first portion during assembly of said capsule to prevent accidental disassembly thereof due to heating and consequent expansion of said air. A container for prepackaging materials which must be kept separate until just prior to use comprising; a. a generally cylindrical first portion having an outer surface, an open top end, and a closed bottom end defining a chamber; b. a generally cylindrical second portion having an open top end, an open bottom end, an inner surface, and an outer surface and having a barrier spaced between said ends with a constricted opening therethrough adjacent said inner surface, said barrier having a top surface, and said second portion having its bottom end secured to the top end of said first portion; and c. a third portion having an axially positioned chamber therein and one end having sliding means adapted to engage the top surface of said barrier in said second portion and close said opening and means for rotatably connecting said one end with the top end of second portion, said third portion also having a conduit extending from said chamber through said sliding means so that rotation of said third portion with respect to said second portion causes said conduit of said third portion to be aligned with said opening in the barrier of said second portion to connect said chamber in said third portion with the chamber in said first portion.
