A mold includes a first mold for receiving a neck mold that holds a neck part of a resin preform having a bottom, and for enclosing the preform inside, and a second mold inserted into the neck mold. At least one of a first sliding surface between the neck mold and the first mold and a second sliding surface between the neck mold and the second mold includes a solid lubricant embedded therein.

A method of after-cooling of the bases of blown out containers, wherein after the transfer of the blown out containers from a blow molding machine to a run-out star wheel which directly follows the blow molding machine along a conveying direction of the containers a cooling of the bases of the containers is carried out by at least one apparatus for cooling the bases. The cooling of the bases of the containers starts immediately during a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow molding machine after the blowing out.

A method of producing a resin container includes injection-molding a resin intermediate molded body of bottomed cylindrical shape as a first injection-molding, injection-molding a resin material outside the intermediate molded body as a second injection-molding, to produce a multilayer preform in which a resin layer is layered on an outer peripheral side of the intermediate molded body, and blow-molding the preform in a state of containing residual heat from injection-molding to produce a resin container having a bottom portion thicker in wall thickness than a body portion. A portion of the inner peripheral side of the intermediate molded body, the portion reaching a bottom portion of the intermediate molded body, has a tapered region in which the wall thickness increases toward the bottom portion.

A heat treatment device for a PET bottle preform with an integral handle includes an air-cooling knife, a heating furnace, and a transport mechanism. The air-cooling knife is disposed on an outlet side of the heating furnace, the bottle preform is transported into the heating furnace through the transport mechanism, heated in the heating furnace, and transported to the air-cooling knife, and the air-cooling knife jets airflow to and cools a lower end of a handle of the bottle preform, appropriately reducing the temperature at junction of the lower end of the handle and a bottle body so that a gentle transition between the temperature of the bottle body and the temperature of the handle is achieved, and the handle is not easily deformed after the bottle preform is blown, thereby effectively improving the quality of the bottle preform after blown.

A thermal conditioning device for thermally conditioning preforms, comprising a heating module provided with an enclosure with a transport volume for said preforms; a heating means and a cooling means that are oriented toward the volume; a control means for controlling said heating and cooling means; said cooling means comprising a circulating means for circulating a flow of air with a nominal flow rate determined by said control means; a channel between said circulating means and said enclosure and leading toward said volume; wherein it comprises, along said channel, a measuring means for measuring the actual flow rate and an adjusting means for adjusting said nominal flow rate with respect to said actual flow rate, by controlling the control means. The invention also relates to a corresponding thermal conditioning method.

Conditioning station tooling for adjusting a temperature of a preform. The tooling comprises a mold presenting a cavity configured to receive at least a portion of the preform. The mold is configured to receive the preform such that a gap is present between the mold and the preform. The mold includes an air inlet and an air outlet. The tooling is configured to permit air to be injected from the air inlet, through the gap between the mold and preform, and out of the air outlet. The tooling further comprises a core configured to be received within an interior of the preform and to contact an interior surface of the preform.
