Abstract
A storage and mixing capsule for separately storing a pair of ingredients therein and providing a structure for efficiently and reliably mixing the ingredients to form an amalgam. The capsule has two components: a first receptacle and a second receptacle . The first receptacle includes an interior compartment for receiving an alloy and includes a piercing element attached to a portion of the inner wall . The second receptacle includes an interior compartment for receiving mercury. The second receptacle further includes a rupturable seal disposed across the open bottom end of the second receptacle . The capsule further includes a conduit extending from the capsule which is used as a passageway for air to move from the interior of the capsule to the exterior of the capsule or for an inert gas to move from the exterior of the capsule to the interior of the capsule to create an interior atmosphere which prevents the oxidization of amalgam components. The second receptacle is additionally adapted to be received by the first receptacle and the two receptacles are movable relative one to another in order to bring the piercing element into confronting relationship with the rupturable seal in order to rupture the rupturable seal and mix the components.
