Claims (1)

[Claims for Utility Model Registration] 1. A first hollow cylindrical member having an open end and a closed end; a second hollow cylindrical member having an open end and a closed end; so as to form one closed cylindrical container; means for joining and fixing the open ends of the first and second cylindrical members; the edges sealingly engage the inner wall of the cylindrical container so as to divide the cylindrical container into two non-communicating interior chambers; a movable flexible disk, one side of which is shaped to match the shape of the inner surface of the opposite end of the container; to maintain a seal between the edge and the inner wall of the cylindrical container; edge pressing means for keeping the edge pressed; a predetermined amount of mercury contained in a first inner chamber defined by one side of the disk, which is shaped to match the edge of the container; 2. A co-reacting amount of metal powder contained within the inner chamber;
and Petstle in the second inner chamber containing the metal powder (
a disposable dental capsule consisting of a pestle); by means of which, when the capsule is placed in an amalgamator, the pestle impacts and displaces the flexible disk and the first A capsule which is fitted with an end face of an inner chamber to force the mercury from the outer periphery of the end of the disk to mix with the metal powder and substantially eliminate one of the inner chambers. 2. The capsule according to claim 1 of the Utility Model Registration Claim, wherein the inner surface of one end of the container is concave, and the opposing surface of the disk is convex. 3. The capsule according to claim 2 of the utility model registration, wherein one side of the disk has a convex conical shape, and the end surface of the container has a corresponding concave conical shape. 4. The capsule according to claim 1, wherein the first hollow cylindrical member telescopically engages the open end of the second cylindrical member around its open end. , having an internal groove extending in the axial direction. 5. The capsule according to claim 4 of the utility model registration, wherein the first and second cylindrical members are
secured in the telescoping engagement by engaging lugs on the member with circumferential flanges projecting from the second member; 6. A capsule according to claim 1, wherein the inner wall of the container includes means for positioning and fixing the edge of the flexible disk. 7. The capsule according to claim 6, wherein the disk positioning and fixing means comprises a circumferential groove in the inner wall for receiving an edge of the disk. 8.
