  • Patent number: 6561804
    Abstract: A receptacle for a filling material is disclosed, which is provided with a plunger which consists, at least in part, of a deformable material on a portion of the plunger which faces the nozzle. In one embodiment, the plunger disclosed can be a double plunger (a two-part plunger) displaceable axially into a defined end position in the direction of the nozzle, the deformable portion of which penetrates into the outlet channel of the nozzle, forcing out the dental filling material located there. It is preferred that the volume of deformable material of the nozzle penetrating into the nozzle is no greater than the volume of the nozzle through which the filling material passes.

  • Patent number: 6425420
    Abstract: A process and device for decanting dental filling substances (2) into special individual containers (3) for use in dental treatment. Storage container (1) is connected leakproof and pressure sealed to conically shaped jet (4) of individual container (3). By applying pressure, dental filling substance (2) is squeezed from storage container (1) through jet (4) into the container body, thereby pushing ahead of it axially movable piston (7) until same reaches a final position determined by circuit-controlled limit stop (10). Thus, a precise dosage can be guaranteed during a long service life, even while filling several individual containers (3) simultaneously. Sensor (11), placed within the range of limit stop (10), records the final position of stop rod (6) conveying the movement of piston (7).
