ABSTRACT:
An apparatus for charging a plastic mass such as dental amalgam through an opening of and into the hollow interior of a capsule such as a magazine for a tooth-filling appliance has a support formed with an elongated passage defining a longitudinal axis and having an outlet end, with a seat at the outlet end snugly interfittable with the capsule over the opening thereof, and with a storage chamber adapted to hold the mass and extending transversely from the passage. A piston is reciprocal axially within the passage between a retracted position to the opposite side of the chamber as the outlet end and in an advanced position as least substantially past the chamber toward the outlet end. This piston is axially displaceable in the passage between these positions for displacing a charge of the mass from the chamber axially along the passage and out of the outlet end into the capsule through the opening thereof. Means is provided for holding the capsule tightly in place over the end of the passage and a plug fitting into the chamber serves to urge the mass into the passage from which the chamber opens.
