  • Patent number: 10759134
    Abstract: A method for three-dimensionally forming a resin packaging member. The resin packaging member is heated to a temperature not higher than the Vicat softening temperature of the packaging member, and then compression shaping is conducted at a temperature not lower than room temperature and not higher than the Vicat softening temperature so as to form a three-dimensionally shaped portion with a large protrusion.

  • Publication number: 20180370704
    Abstract: The present invention relates to a package formed of a resin film including a sealant film with a three-dimensionally shaped portion that protrudes outward. At the three-dimensionally shaped portion that protrudes outward, the sealant film has a thinnest part with a thickness of 50 to 95% of a thickness of the sealant film at any part other than the three-dimensionally shaped portion that protrudes outward, whereby rupture or peeling at the three-dimensionally shaped portion is prevented, and the package has basic functions such as a gas barrier property, a vapor barrier property, a drop impact resistance and a piercing resistance. Further, the three-dimensionally shaped portion is well defined and excellent in the ornamental effect, and the design is improved.

  • Patent number: 8007174
    Abstract: A bag-like container with a spout in which a plastic linear fastener is interposed in an upper part of the container so that when water content or the like is to be supplied after contents of a liquid food container or the like have been administered to a subject, opening and closing the linear fastener enables the water content or the like to be supplied in an uncomplicated manner without the use of a separate member such as a spout that is an open part for pouring food, water, or the like into the container.
