    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a heat-insulating paper container with gas barrier properties. SOLUTION: A raw material 1 for the heat-insulating paper container constituting the barrel part 21 of the paper container 2 is composed by laminating a low melting point olefin resin layer 12, a gas barrier layer 13, an overcoat layer 14, a mixture coating layer 15 comprising a starch containing water-containing starch particles and an adhesive, and a resin layer 16 comprising a low melting point olefin resin in this order on the outside surface of a paper-made substrate 11. The outer face side of this raw material 1 for the heat-insulating paper container is heated and sucked under vacuum, and by evaporation of water content in the starch particles included in the mixture coating layer 15 of the water-containing starch and the adhesive, a foamed layer 16a with a high thickness and with closed cells is formed. In this invention, an efficient manufacturing method is provided in which after a blank manufactured by continuously foaming a roll of the raw material for the heat-insulating paper container is prepared, it is molded to obtain the heat-insulating paper container.

    • PROBLEM TO BE SOLVED: To provide a lid body wherein no wrinkle and ruled line exist on the side face, a curling part and a side wall crosssection are hardly seen from the top face side of the lid body, the top face of a circular lid is largely exposed, and a picture design printed face is widely seen, in a two-piece type cylindrical lid made of a paper. SOLUTION: The two-piece type cylindrical lid made of the paper is manufactured by sticking a paper-made cylinder forming a side wall and a paper-made disc forming the top face. A folded part is formed by folding the vicinity of the upper end of the cylinder forming the side wall toward the center part of the cylinder, and the disc is stuck on the outer face of the folded part. In addition, when the diameter of the disc is made approximately the same as the outer diameter of the cylinder, the appearance becomes favorable. Furthermore, an embodiment which shows that the base of the folded part is folded in the lower direction of the side wall to form a bank, and that the disc enters thereinto, is preferable.

    • 要解决的问题:为了提供一种在侧面没有皱纹和划线的盖体,从盖体的顶面几乎看不到卷曲部分和侧壁横截面, 圆形盖很大程度上暴露出来,并且在由纸制成的两片式圆筒形盖中广泛地看到图像设计印刷面。

      解决方案:由纸制成的两片式圆筒盖通过粘贴形成侧壁的纸制圆筒和形成顶面的纸制盘而制造。 折叠部分通过将形成侧壁的圆筒的上端附近朝向圆筒的中心部分折叠而形成,并且将盘卡在折叠部分的外表面上。 此外,当盘的直径与圆筒的外径大致相同时,外观变得有利。 此外,优选的是,示出折叠部的基部在侧壁的下方折叠以形成堤,并且盘进入其中的实施例。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a corrugated fiberboard box for frozen food which is suitable for the long-term preservation of frozen food.
      SOLUTION: In the corrugated fiberboard box for frozen food formed of double-side corrugated fiberboard sheet, a liner located on the inner side of the box is a laminate paper of a three-layered structure of a paper layer/a synthetic resin layer/a paper layer, and the corrugation height of the corrugated fiberboard sheet is 0.5-1.5 mm. The corrugated fiberboard sheet is affixed to each other with a waterproof adhesive. A liner located on the outer side of the corrugated fiberboard box is a coated white paperboard. The synthetic resin layer is formed of polyethylene, and contains plate-like pigment.
