している。By the way, this laminated plastic bottle is usually manufactured by the method described below. at first,
A laminated parison or laminated preform (hereinafter referred to as laminated parison) having a laminated structure corresponding to the laminated plastic bottle to be manufactured is molded by means of extrusion molding or the like, and at the time of this molding, it extends along the axial direction. The joint portion is provided at a predetermined position so that the outer layer and the inner layer can be separated except for the joint portion. Then, this laminated parison or the like is set in a mold and molded into a desired bottle shape by a blow molding method. Then, after forming into a bottle shape in this manner, air holes 34 are punched in the outer layer 31.

When the diameter of the air hole 34 is equal to or smaller than the lateral width of the joint portion 33 and the joint portion 33 and the air hole 34 are overlapped as shown in the plan view of FIG. This is because the air is blocked and air does not flow between the outer layer 31 and the inner layer 32, so that the inner layer 32 cannot be contracted.
