ABSTRACT:
A multicompartment mixing capsule which is particularly useful for storage and subsequent intermixing of mercury and silver or a silver alloy to form a dental amalgam material. The amalgam components are contained in separate capsule chambers which are insulated by a diaphragm having a thin frangible perimeter, and a thickened and strengthened center portion. A pestle in one of the chambers impacts the diaphragm during initial capsule shaking in an amalgamator to rupture the frangible diaphragm perimeter, and thereby to permit complete and unimpeded intermixing of the amalgam components.
