ABSTRACT:
In a hollow resin container, at a connecting portion between a separator and a resin layer, through-holes, 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. The surfaces of bottom portions of the through-holes, which surfaces are coplanar with and continuous with the inner side surface of the hollow resin container, are covered with the gas barrier sheet. Namely, a cross-sectional area S of the separator 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 and the resin layer, a region at which the gas barrier sheet does not exist is made small. Therefore, sealability at the connecting portion can improve.
