    摘要： Double blow molding process comprising a first blow molding step for performing biaxial orientation blow molding of a preform into a first intermediate molded item, a step for heating the first intermediate molded item in an oven so as to perform forced shrink molding thereof into a second intermediate molded item, and a second blow molding step for performing blow molding of the second intermediate molded item into a bottle body, wherein the temperature of the second intermediate molded item just before the second blow molding step is adjusted to at least 40°C or at least 50°C higher than the temperature of a metal mold used in the second blow molding step. Conditions for double blow molding can be chosen in conformity with the heat resistance demanded for the bottle body, so that the bottle body having the demanded heat resistance can be obtained in high productivity.

    摘要： 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.

    摘要翻译： 双吹模法包括将预成型坯双轴拉伸和吹塑成初级中间产品的一次吹塑成型步骤，加热初级中间产品以将其收缩成二次中间产品的步骤和二次吹塑步骤 将二次中间产品成型为瓶子。 这种双吹模法的特征在于，在二次吹塑步骤之前，备用的二次中间产品保持在比所述二次吹塑步骤中使用的模具温度高至少40℃或50℃的温度 。 从这样的温度，可以确定双重吹塑条件，其可以对应于瓶子所需的耐热水平，并且以高生产率提供具有必要的耐热水平的瓶子。
