发明名称 Method and Apparatus for Blow Molding Aseptic Containers
摘要 An apparatus and method for blow molding and sealing an aseptic container. A pair of mold halves, including inner surfaces that when closed define a mold cavity, clamp about an extruded parison. The parison is inflated by high pressure blow air into conformity with the shape of the mold cavity. An evacuation device applies a force to an exterior portion of the blow molded container causing the portion to deform or flex inwardly, thereby reducing the internal volume and evacuating air from the blow molded container. A sealing tool thereafter causes the blow molded container to be sealed while the container is in the reduced volume condition. Upon removal from the mold assembly and cooling, the container returns to the desired shape.
