  • Patent number: 5988250
    Abstract: An apparatus for producing containers with a film made of thermoplastic synthetic material, having elements for advancing, along an advancement direction, two facing strips of film made of thermoplastic synthetic material; a thermal bonding station including thermal-bonding half-molds which face said two strips of film on opposite sides thereof along the advancement direction of the two strips of film, the thermal-bonding half-molds being adapted to thermally bond the strips of film to each other at preset regions thereof so as to form thermal bond regions delimiting between the two strips of film, a plurality of pouches that are each open at a longitudinal edge end of the two strips of film; a cooling station arranged downstream of the thermal bonding station along the advancement direction and including cooling half-molds being shaped so as to carry out a film strip cooling which is limited only to the thermal bond regions; a thermoforming station, arranged downstream of the cooling station and including a

  • Patent number: 5743988
    Abstract: A method for producing containers, such as bottles or the like, with a film made of thermoplastic synthetic material, and to an apparatus for performing the method. The process comprises: a step for thermally bonding two strips of film made of thermoplastic synthetic material that face one another, so as to form, between the two strips of film, pouches that are open at a longitudinal edge of the strips of film; and a thermoforming step, during which a segment of the two strips of film, in which the pouches are formed, is inserted in a forming mold that is provided with molding cavities located at the pouches, and a pressurized fluid is injected into the pouches through their open side to form them, by plastic inflation, inside the molding cavities.
