ABSTRACT:
The invention relates to a method and a capsule for the storage and mixing of the two co-reactive basic materials for dental amalgam. The capsule comprises an elastically bendable length of tube bent into V-shape with the arms each forming chambers and with the tip between the arms forming a point of separation between the chambers. Each of the basic materials is accommodated and stored in its own chamber and can be mixed by straightening out the length of tube, the ends of which are sealed, so that the point of separation is opened up, and by shaking the length of tube in its axial direction. The invention also relates to a method in manufacturing the capsule in which the tube length prior to bending into V-shape is pre-shaped in one section at the center of the length of the tube by providing two transverse points of compression which are mutually separated by an intervening section.
