Abstract: In a manufacturing method for a delamination container, in a first injection molding, a first recess portion is formed by a first protrusion portion in at least part of a first layer. In a second injection molding, a second recess portion which penetrates the first layer and through which a surface of a second layer is exposed is formed in a preform by inserting a second protrusion portion into the first recess portion. During a blow molding, the second recess portion is stretched to form an air introduction hole in an outer layer of the delamination container.

Abstract: A blow mold method for a double-walled container, including: blowing in which an intermediate molded article is molded by stretch blowing a preform housed in a die; and pressing in which the intermediate molded article is pressed inside the die and a double-walled container is molded. During the pressing, an internal floor-corresponding section is pressed such that internal wall-corresponding section is inverted as far as the inside of an outer wall-corresponding section, in a state in which heat retention is maintained such that the internal wall-corresponding section can be inverted as far as the inside of the outer wall-corresponding section.

Abstract: A manufacturing method includes an injection molding process of injection-molding a preform having a two-layer structure including an outer layer preform and an inner layer preform, and a blow molding process of blow molding the preform to mold a delamination container made of resin. The injection molding process includes an outer layer molding process of filling an outer layer injection mold with PET (outer layer resin material) to mold the outer layer preform and molding a thin film portion in a part of the outer layer preform, and an inner layer molding process of injecting PP (inner layer resin material) toward the thin film portion to break the thin film portion and filling an inner layer injection mold with PP having a temperature lower than a melting point of PET via the broken thin film portion to mold the inner layer preform.

Abstract: A method for manufacturing a double-wall container includes a blow molding process of forming an intermediate molded body by blow molding, the intermediate molded body including a projection part that is provided at a boundary portion between an inner wall forming part and an outer wall forming part and projects outward in a radial direction of the outer wall forming part; an inverting process of pushing the inner wall forming part inside the outer wall forming part and inverting the inner wall forming part, thereby forming the intermediate molded body into the double-wall container; and a collapsing process of collapsing the projection part in a depth direction of the intermediate molded body to form a crease at the boundary portion between the inner wall forming part and the outer wall forming part, the collapsing process being performed before the inverting process.
