PROBLEM TO BE SOLVED: To create a form of an air suction hole in which peeling of an outer layer and an inner layer can be proceeded with smoothly and certainly near an opening peripheral edge part of the air suction hole, relating to a delamination bottle.SOLUTION: A blow molding container includes a synthetic resin-made outer layer (11) which forms a regular outer shell, and a synthetic resin-made inner layer (12) which is stacked on the outer layer (11) as capable of peeling, with an air suction hole (14) opened at the outer layer (11) by a punch cutter, at a predetermined position of a mouth tube part (2). The shape of the air suction hole (14) at an inner surface side end part of the outer layer (11) is diameter-enlarged as a trumpet shape, so that, a notch-like gap (N) is peripherally provided at the opening peripheral edge part of the air suction hole (14) and between the outer layer (11) and the inner layer (12). |
