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: One purpose of the present invention is to provide a mold unit which is capable of achieving improvements in both energy efficiency and heat resistance performance; a blow molding apparatus; and a blow molding method. The present invention is provided with: a first mold part for performing a first step in which a preform is subjected to heat-set blowing at a first temperature; and a second metal mold part for performing a second step in which an intermediate molded body blow molded as a result of the heat-set blowing is blow molded at a second temperature lower than the first temperature, to produce a container. The first mold part and the second mold part are disposed adjacently to each other.
