Abstract: A biaxially drawn, blow-molded bottle and its preform comprise at least a layer of a gas barrier material laminated inside the PET resin layers, a functional portion having a screw thread raised spirally in the upper portion of neck and also having a stop ring disposed under the screw thread, and a neck ring disposed at the lower end of the neck. In these preform and bottle, the leading edge of the gas barrier layer is positioned at a half height of the neck ring where the most advanced front of the leading edge neither reaches a half height of the stop ring nor extends to the functional portion. It is intended here that the neck would not be affected by the shrinking deformation caused by the existence of the gas barrier layer in the functional portion of the neck, which is treated for thermal crystallization.

Abstract: A method for producing bottle-type containers made of a synthetic resin, e.g., polyethylene-terephthalate resin, includes a heat treatment step for heating and crystallizing a neck portion of a perform corresponding to a neck portion of a container. In a first stage of the heat treatment step, the neck portion of the perform is temporarily heated to a temperature below a melting point of the synthetic resin, e.g., approximately 200° C. to 230° C. in the case of polyethylene terephthalate resin. In a subsequent second stage, the neck portion is maintained at a temperature within a range in which crystallization of the synthetic resin is promoted, e.g. approximately 170° C. to 195° C. in the case of polyethylene terephthalate resin.

Abstract: A multiplayer perform having at least a medium or intermediate gas barrier layer is prepared in advance by the injection molding of this perform in a predetermined shape that corresponds to the shape of a finished molded product. The body portion of this perform is heated to a blow moldable temperature. The heated perform is set in a primary blow mold (12), and is blow molded in the biaxial orientation to give a primary molded intermediate (5). The primary intermediate (5) is then heated to deform it forcibly by thermal shrinkage and thereby to give the secondary molded intermediate (6). The shrunken secondary intermediate (6) is set in a secondary blow mold (13), and is subjected to the secondary blow molding in the biaxial orientation to obtain a finished molded product, which is fixed thermally to give heat history to the PET resin.

Abstract: The double blow molding process comprises a primary blow molding step of biaxially drawing and blow molding the preform into a primary intermediate product, a step of heating the primary intermediate product to shrink-mold it into the secondary intermediate product, and a secondary blow molding step of molding the secondary intermediate product into a bottle. This double blow molding process is characterized in that, just before the secondary blow molding step, the secondary intermediate product on standby is maintained at a temperature at least 40° C. or 50° C. higher than the mold temperature used in said secondary blow molding step. From such a temperature, it is possible to determine the double blow molding conditions, which can correspond to the levels of heat resistance required for the bottles, and to provide, with high productivity, the bottles having necessary levels of heat resistance.
