Zusammenfassung:	Process for forming one or more air intake holes in a laminated, blow-molded container comprising an outer layer (11) and an inner layer (12), wherein the outer layer is cut through with a punch-cutter (43) at a predetermined position or positions of a neck (2) to form one or more air intake holes (14), wherein the punch-cutter to be used has a cylindrical blade (44) at the tip, and also has a hooking portion or portions (45), which is/are disposed on an inner peripheral surface of the cylindrical blade and which perform a function of hooking into a portion of the outer layer that has come inside the cylindrical blade, the cylindrical blade is pressed forward until a blade edge (44p) comes to a position quite close to an inner surface of the outer layer, then, the cylindrical blade is moved backward, and the cut piece is taken out in a completely cut shape so that the air intake hole is cut out as a through-hole.
