  • Patent number: 6370842
    Abstract: An object is to prevent roughening of a rupture surface of a packaging material (12) that is formed upon opening of a spout (21) through application of an external force. There are provided transport means for transporting a layered packaging material (12) that is formed of a paper substrate and resin films and that has a rupture area (52) at a location corresponding to that of opening means; a seal unit for sealing the packaging material (12); and heating means disposed on the upstream side of the seal unit in the transport direction of the packaging material (12) such that the heating means is opposed to an innermost layer of the packaging material (12) in order to heat the packaging material (12). In this case, after being heated and melted, the resin film of the packaging material (12) is gradually cooled. As a result, thermoplastic resin that constitutes the resin film is crystallized and becomes brittle.

  • Patent number: 6192660
    Abstract: An apparatus for supplying and applying cap bodies (51) to a packaging container includes a gas supplying device (11) which supplies a hydrogen-oxygen gas mixture obtained by electrolyzing water, a burner unit (22) that is connected to the gas supplying device (11) for receiving hydrogen-oxygen gas mixture from the gas supplying device (11) and burning the hydrogen-oxygen gas mixture and a pickup apparatus (80) which transports a cap body (51) to a heating position above the burner unit (22). The burner unit (22) is provided with a plurality of nozzles (31) that are arranged in a pattern that corresponds in shape to the shape of the underside periphery of the cap body (51). A shield plate (57) is positionable above the nozzles (31) to deflect the hydrogen-oxygen gas mixture emitted from the nozzles (31), and an igniter (32) is disposed adjacent one of the nozzles (31), to ignite the mixture emitted from the nozzle (31).

  • Patent number: 4560661
    Abstract: Disclosed is a process for purifying an enzyme contained in a solution such as cell extract liquor or fermentation culture liquor. The crude enzyme solution is brought into contact with either a strongly acidic cation exchange resin of high porous type or a strongly basic anion exchange resin of high porous type to adsorb the enzyme on the resin. An eluting agent is then passed through the resin to elute out the enzyme as a purified enzyme solution.
