ABSTRACT:
A device for storing, transporting and mixing reactive ingredients, such as mercury and silver for dental amalgam, includes a thin, rupturable membrane dividing the two chambers of a capsular container into two non-communicating closed compartments, one for each of the reactive ingredients, the chamber of larger volume (major chamber) also including a pestle. Unlike conventional devices of this type, the membrane is ruptured substantially completely intact, i.e. without presenting any loosened or torn fragments of the membrane which could contaminate the mixed ingredients simply by inserting the capsule in an amalgamator or similar vibrating or shaking device. Since no manipulation of the capsule, such as telescoping, bending, twisting etc is required, mixing of the components can be performed with a minimum amount of effort.
In an alternative embodiment, one of the substances to be mixed, such as silver powder for dental amalgam, is provided in the larger volume chamber in the form of a tablet or pellet and the pestle can be omitted. In this case, the tablet itself ruptures the membrane.
