The instant invention relates to disposable capsules which contain coreactive components in separate chambers and means for automatically combining and mixing said coreactive components prior to opening the capsule. The instant disposable capsules may contain dental amalgam precursors such as mercury and silver which may be combined and mixed merely by placing such capsule in a dental amalgamator. The disposable capsules comprise a hollow cylindrical section closed at one end and having an internal constriction spaced from the other end, and a movable insert comprising a stem having an upper portion inserted through and frictionally engaging said constriction and a flange extending outwardly about the lower end of said stem and frictionally engaging the inner wall of the hollow cylindrical section, whereby said flange initially divides said cylinder into two noncommunicating chambers. |
