<p>In a hollow resin container (10), at a connecting portion between a separator (16) and a resin layer (30), through-holes (36,38), each of which has a surface which is coplanar with and continuous with an inner side surface of the hollow resin container and whose axial direction cross-sectional configuration is triangular, are formed at a base portion of the separator (16). The surfaces of bottom portions of the through-holes (36,38), which surfaces are coplanar with and continuous with the inner side surface of the hollow resin container, are covered with the gas barrier sheet (32). Namely, a cross-sectional area S of the separator (16) at the connecting portion in a plane which is coplanar with the inner side surface of the hollow resin container is smaller than a cross-sectional area S4 of the separator in a plane parallel to the aforementioned plane and at a region at which the through-holes are not formed (S4 > S). As a result, at the connecting portion between the separator (16) and the resin layer (30), a region at which the gas barrier sheet does not exist is made small. Therefore, sealability at the connecting portion can improve. <IMAGE></p> |
