ABSTRACT:
In a biaxial stretch blow molding apparatus (10) for wide-mouthed containers, preforms (6) that are in an inverted state are conveyed on a single plane by preform carriers (40) that go around a carrier circuit (30) in the form of a loop, are heated via a heating station (60), and are then transferred via a transfer station (80) to stretch blow molding mold assemblies (72) that go around a circular looped path (71). The molded wide-mouthed containers (1) are taken out of the stretch blow molding mold assemblies (72) along a conveying path on a same plane and collected by a collection station (90). Wide-mouthed containers can be formed continuously and at high speed, which is less wasteful and more economical than the case where wide-mouthed containers that are formed from films.
