Furthermore, at least one first connector element arranged on the central mold part and at least one second connector element arranged on the outer mold half are provided, said second connector element being operatively connected to the first connector element at least in a closed configuration of the molding device.

A manufacturing device of the present invention includes an intermediate molded body mold having a first accommodating space capable of accommodating a plurality of preforms, each preform having a mouth portion and a trunk portion; an intermediate molded body blowing unit configured to blow gas into the plurality of preforms arranged in the first accommodating space to inflate the plurality of preforms, thereby manufacturing an intermediate molded body having a connection portion formed by the trunk portions of the plurality of preforms welded to each other; a final molded body mold having a second accommodating space larger than the first accommodating space; and a final molded body blowing unit configured to blow gas into the intermediate molded body arranged in the second accommodating space to inflate the intermediate molded body, thereby forming an exterior shape of a multiple-chamber container.

A blow molding apparatus comprises: a continuous transport section 150 provided with a loop-shaped transport path 151 for continuously transporting a preform 200; an intermittent transport section 160 for intermittently transporting the preform 200 to a blow molding section 140; and a delivery section 170 for holding the preform 200 being transported on the transport path 151, and delivering it to the intermittent transport section 160. The delivery section 170 is equipped with a cooling means 300 for jetting a cooling fluid from a first nozzle member 301 onto an outer surface of the preform 200 to cool the preform 200 locally.

Provided is a resin container manufacturing method including: an injection molding process of injection molding a plurality of preforms along a predetermined arrangement direction; a temperature adjustment process of adjusting a temperature of the preform; and a blow molding process of molding a resin container from the preform. After the injection molding process, the preform and the container are conveyed along a conveying direction intersecting the arrangement direction over the temperature adjustment process and the blow molding process. The temperature adjustment process includes a first temperature adjustment process of adjusting the temperature of the preform, a second temperature adjustment process of adjusting the temperature of the preform under a condition different from that of the first temperature adjustment process, and a fine adjustment process of finely adjusting the temperature of the preform.

This resin-made container is provided with: a neck portion having a content inlet-outlet portion; a lateral surface portion connected to the neck portion; and a bottom portion that is disposed on the side opposite to the neck portion and that is connected to the lateral surface portion. The resin-made container is produced by a stretch blow molding process. The bottom portion has formed therein a bulge section that protrudes downward in the vertical direction. The bulge section is disposed in an eccentric region, of the bottom portion, positioned outside a region demarcated by perpendicularly projecting an opening plane of the inlet-outlet portion of the neck portion.

A device and a method for producing a preform having a shoulder and base geometry optimized for subsequent stretch blow molding, since the preform cannot be produced according to the conventional injection-molding method. For this purpose, the preform produced in the injection-molding tool is transferred into a conditioning station and is conditioned and cooled in the shaft while no contact is made with the top of the preform and the preform shoulder on account of a special contour of the conditioning receptacle. Due to the reheating of these preform regions they can be mechanically deformed into a new geometry which is advantageous for the blow molding process and thus their wall thickness can also be influenced. In the subsequent blow molding process the deformed preform has the advantage that the plastic material which is distributed better in the bottle results in considerable material savings and higher quality bottles.

A container manufacturing device is provided. In detail, the container manufacturing device for performing manufacture of a container pre-form and container molding in a single station via one stop. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to a pre-form completed by the pre-form molding module to expand the pre-form and to form the shape of the container, and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.
