摘要

A capsule for a tooth-restoring material includes a cylinder containing therein the predetermined amount of a powder component of the tooth-restoring material and fitted at its rear end with an extruding plunger; a breakable package held in front of an extreme end opening in the cylinder, the package containing therein an amount of a liquid component of the tooth-restoring material and having its cylinder-facing side formed of a weak material; and a member for holding the package having a nozzle at its outermost end; wherein at a position of the plunger corresponding to the extreme end opening in the cylinder is provided a member capable of breaking through the package of a size small enough not to close up the opening and the nozzle, when the plunger moves to and reaches the package-holding member.
