PURPOSE: To mix and use a material for tooth recovery to be composed of powder and liquid by spirally engaging a male screw, which is spirally provided in the tip of a cylinder in a capsule main, body, and a female screw, which is spirally provided in a pack holding body, mutually and exploding a pack for press explosion in a weak material side.

CONSTITUTION: For example, a female screw 4b of a pack holding body 4 is spirally engaged to a male screw 2d of a cylinder 2 and a pack 3 for press explosion is pressed and exploded in the weak material side of the cylinder 2 side. In such a case, the pack for press explosion is exploded after the weak material of the cylinder 2 side is expanded in an opening part 2b on a center axis in the tip of the cylinder 2 and an opening part 2b' to be dislocated from the center axis. When liquid B flows into the cylinder 2, a capsule 1 for tooth recovering material is immediately set to an exclusive mixer, mixed and kneaded with powder A of the tooth recovering material, which is housed to the cylinder 2 in advance. After that, a recessed part 2c for engagement is engaged to a presser such as an applier and a pack breaking body 2e pass through the opening part 2b on the center axis of the cylinder 2.
