ABSTRACT:
A mixing capsule for mixing a first material with a second material (e.g. to prepare a dental silver amalgam) comprises a pair of tubular housing sections removably attached to each other and defining between them a first chamber for receiving the first material to be mixed. The second housing section includes a partition integrally joined to its inner surface by a thin connecting web, and a tubular neck above the partition. A plunger is disposed in the neck of the second housing section, the lower face of the plunger defining with the partition a second chamber for receiving the second material to be mixed, the plunger being depressable to cause the partition to be severed along its connecting web from the inner surface of the second housing section and thereby to cause the material in the second chamber to drop into and mix with that in the first chamber.
