<p>A system for making blow molded receptacles (22) is disclosed generally comprising two mold portions (104,106) that, when positioned adjacent each other, at least partially enclose a cavity (128) defined by a molding surface (129), against which the walls of a blow molded receptacle (22) are blown. One of the portions is a mold core, which has a base surface (130) and a raised portion (132) extending out from the base surface (130) into the cavity (128). The raised portion (132) has an outer surface (134) and a side surface (136), which results in a corresponding, inner sidewall on the blow-molded receptacle (22). The raised portion houses (132) a punch (160) partly disposed in an opening in the side surface for punching a hole in the sidewall (36). In some embodiments, the side surface is substantially perpendicular to the seal between the two mold portions (104,106), and an actuator (162) displaces the punch (160) in a direction substantially parallel to the seam (108).
