本発明は湿気や酸化を嫌′う内容物を収納するための、
ガスバリア性を有するバリア性容器及びその製造方法に
関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a container for storing contents that dislike moisture and oxidation.
The present invention relates to a barrier container having gas barrier properties and a method for manufacturing the same.
近年、ブリキ缶、アルミ缶等の金属缶に代わるような安
価でしかも軽く、酸素又は水蒸気等に対して高いバリア
性を有するような射出樹脂によって形成されたバリア性
容器が出現している。In recent years, barrier containers made of injection resin that are inexpensive, lightweight, and have high barrier properties against oxygen, water vapor, etc. have appeared, replacing metal cans such as tin cans and aluminum cans.
これら容器は、第８図に示すように、バリア膜シ一ト５

た。These containers have a barrier film sheet 5 as shown in FIG.
0, a circular blank 51.51 is cut out, and the periphery of this blank 51 is folded to form a rising wall 52, while a barrier film molded body 53 (FIG. 9) having almost the same shape as the container is molded, and this is used for injection molding. A shallow-bottomed container 54 (10th (Fig.) was manufactured.
しかしながら、従来のこの種バリア性容器においては、

製造することができなかった。However, in conventional barrier containers of this type,
When molding the barrier film molded body 53, since the flat barrier film blank was folded and molded, wrinkles were formed as shown in FIG. 9. For this reason, there was a risk that pinholes would occur due to these wrinkles, and only shallow containers could be manufactured.
本発明はかかる点に鑑み、皺がなく、しかも底深のバリ
ア性容器及びその製造方法を提供することを目的とする
。In view of the above, an object of the present invention is to provide a wrinkle-free barrier container with a deep bottom and a method for manufacturing the same.

した。In addition, a cylindrical barrier film having a bottom is formed from a metal foil barrier film formed by drawing a metal material into a cylindrical shape, and a bottom formed body having a bottom surface and a relatively shallow rising portion rising from the periphery of the bottom surface. Then, this barrier film body is placed on a molded male mold, a cavity is formed by combining the molded male mold covered with this barrier film body and a molded female mold, and a molded resin is injected into this cavity. The container body was configured to be integrally molded so that the barrier film covered the inner surface of the container body.

なる。The cylindrical barrier film body with a bottom part is integrally molded with injection resin from a cylindrical barrier film body and a bottom molded body having a bottom face and a relatively shallow rising portion rising from the periphery of the bottom face. There is no risk of wrinkles forming in the barrier film on the side wall of the container. Therefore, it is possible to mold a container with a deep bottom without the risk of bottle holes being formed, and by printing on the barrier film in advance, it is possible to print on the container without the risk of peeling off.
