Abstract: In the process of closing a blow cavity split mold 14, a roller 32 is allowed to directly contact a bottom surface 38 of a guide block 36 and roll thereon. Thus, the mold clamping movement of the blow cavity split mold 14 is guided, without clearance from the guide block 36. Consequently, the upward movement of the blow cavity split mold 14 is regulated.
Abstract translation: 在关闭吹塑腔分离模具14的过程中，允许辊32直接接触引导块36的底表面38并在其上滚动。 因此，吹塑腔分离模具14的模具夹紧运动被引导，没有与导向块36的间隙。因此，调节吹塑腔分离模具14的向上运动。

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: In one embodiment of this invention, a blow nozzle, which introduces blow air into a molded article in which a flange portion is supported by a blow cavity mold, includes a nozzle main body and an outer nozzle. The outer nozzle includes a first surface brought into press contact with the flange portion and a second surface disposed further outwards in a radial direction than the first surface and being brought into contact with the blow cavity mold. From when the nozzle main body is moved and the first surface is brought into contact with the flange portion to when the second surface is brought into contact with the blow cavity mold and the movement of the nozzle main body is stopped, the first surface of the outer nozzle is overdriven so that the flange portion is airtightly sealed by the first surface.
