0, a circular blank 51.51 is cut out, and the periphery of this blank 51 is folded to form a rising wall 52 to form a barrier membrane molded body 53 (FIG. 10) that has almost the same shape as the container, and this is injection molded. A shallow-bottomed container 54 (No. (Fig. 11) was manufactured.

った。However, in conventional barrier containers of this type,
When shaping the barrier film molded body 53, since the flat barrier film blank was folded and shaped, wrinkles were formed as shown in FIG. 12. For this reason, there was a risk that pinholes would occur due to these wrinkles, and only shallow containers could be manufactured. In addition, when printing on containers due to these wrinkles, it was not possible to use a pre-printed barrier film, so printing was applied to the surface of the container, but this type of printing had the problem of easily peeling off. .
本発明はかかる点に鑑み、皺がな＜、シかも底深のバリ
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 barrier container with no wrinkles and a deep bottom, and a method for manufacturing the same.

構成した。Therefore, in the present invention, the barrier container partially includes a cylindrical barrier film body having a bottom formed of a barrier film made of metal foil, paper, and at least one resin layer. The method for manufacturing a barrier container includes a container body integrally molded with injection resin to form the inner surface of the container, and a barrier film made of metal foil, paper, and at least one resin layer on the bottom. The barrier film body is formed into a cylindrical barrier film body having The container body was configured to be integrally molded so that the body formed the inner surface of the container body.
