ABSTRACT:
Effective sterilization is obtained in an apparatus for producing a succession of containers from a length of foil, charging the containers and closing the charged containers in a sterile environment, where the deep-drawing station for forming the containers in the foil includes a vertically reciprocable lower portion defining a mold recess for receiving and forming respective containers in the foil and a stationary upper portion associated with the lower portion and defining a chamber in communication with the mold recess. The stationary upper portion of the deep-drawing station is heated, a supply conduit is connected to the upper portion for delivering a sterilizing fluid into the upper portion chamber under pressure, a discharge conduit is connected to the upper portion for exhausting the sterilizing fluid, a vertically reciprocable punch is mounted in the upper portion for reciprocation to the bottom region of the respective container, and a sterilizing fluid discharge channel passes through the punch and is in communication with the bottom region, the discharge channel being connected to the discharge conduit.
