    Abstract: A method of producing a blow-molded PET container suitable for hot-filling includes the steps of injection molding a preform, blow-molding the preform into a primary molded article larger than the desired final container, heating the primary article in a series of oven chambers while its mouth is sealed so that pressure builds within the article to thereby control shrinkage, and blow-molding the shrunken article into the desired container. The two molds are preferably heated, and the mold contact time is as long as allowed by the manufacturing process to help remove internal stresses in the article. An apparatus for carrying out the method includes a first machine having an injection station, a thermal conditioning station, a primary blow-molding station, and an exit station. A second machine includes the oven chambers and a final blow-molding station. The primary article is sealed by a cap member that has a pressure relief valve connected to it to limit the internal pressure during heating, an air supply passage for final blow-molding, and a tensioning rod for insertion into the primary article and engaging a pocket in the center of the article's bottom. In some applications, it is necessary to stiffen the neck, particularly when hot-filling at about 200.degree. F. or higher, or when using a closure roll-on die or a lugged neck finish to apply a bottle cap to the final container.

    Abstract: A blow molding apparatus having two rows of holding plates each for holding a plurality of preforms; supporting and conveying means for conveying the two rows of holding plates into a blow molding station while slidably supporting the holding plates so that the row pitch in the rows is variable; two rows of blow molds arranged in the blow molding station corresponding to the two rows of holding plates, each row of the blow molds being adapted to blow mold the preforms; and a linkage for changing and setting the row pitch in the rows of holding plates. The linkage includes two first support shafts arranged respectively on the opposite end faces of the two rows of holding plates in a direction perpendicular to the direction of the pitch; two first links each rotatably supported around the corresponding one of the first support shafts; and two second support shafts each for rotatably supporting the other end of the corresponding one of the first link in the coaxial or non-coaxial manner, whereby the row pitch of the holding plate rows can be changed by the vertical movement of the second support shafts.

    Abstract: The present invention provides a blow molding apparatus which conveys preforms to a blow molding stage while holding the preform by two rows of supporting plates, places the preforms in two rows of blowing molds disposed corresponding to the supporting plates, blow molding the preform into hollow containers when the blowing molds are in their closed positions, thereafter opening the blowing molds to remove the molded containers therefrom. In this blow molding apparatus the row pitch between the supporting plates is changed between one when the blowing molds are opened and another when the blowing molds are in the other conditions. In this apparatus, the row pitch between the supporting plates is not required to maintain the maximum pitch when the blowing molds are opened. Thus, the blow molding system may be reduced in size and occupying area.

    Abstract: A multi-layer forming nozzle includes a valve member which can open and close a flow passage for molten resin which forms an intermediate layer of a multi-layer molded product by injection molding. The valve member is operated in response to resin pressure differentials at the front and back of the valve member to accurately switch from a multi-layer operation to a single layer operation and vice versa. A three-layer nozzle in accordance with the invention has a nozzle body provided interiorly with a first resin path, a second resin path and a third resin path in the form of a concentric circle bending to the same injection opening. The valve member is located either in a mouth portion of the third resin path in the central portion positioned internally of a mouth portion of the second resin path or a mouth portion of the second resin path in the intermediate portion positioned internally of the first resin path. The valve member is moved forward and backward in response to resin pressure differentials to open and close the valve member.

    Abstract: In a configuration in which a guide member that guides an intermediate member to be slidably movable is provided on an upper surface of side support plates, a bending buffer portion is provided in a first region of the side support plates which is located more outward than a part of the side support plates on which the guide member is provided. The bending buffer portion is configured to be bent and deformed easier than a second region of the side support plates in which the guide member is provided.
