摘要： A method is disclosed for thermally conditioning an essentially tubular parison of polyethylene terephthalate material to a desired orientation temperature at which the polyethylene terephthalate material can be biaxially stretched. The method comprises the steps of heating the parison by applying heat to the exterior surface thereof until the surface reaches a maximum heating temperature less than the temperature at which the polyethylene terephthalate material begins to crystalize and then cooling the heated exterior surface of the parison to remove the heat therefrom while the heat within the wall of the parison diffuses therethrough to raise the temperature of the opposing interior surface toward the desired orientation temperature. The method further includes the subsequent steps of reheating the parison by applying heat to the cooled exterior surface thereof until the surface reaches a temperature no higher than the maximum heating temperature to again add heat within the wall of the parison and then recooling the reheated exterior surface of the parison to again remove the heat therefrom until the additional heat within the wall of the parison diffuses therethrough to further raise the temperature of the opposing interior surface to approximately the desired orientation temperature so that the temperature through the wall of the parison is substantially uniform from the reheated exterior surface to the opposing interior surface.
摘要翻译：公开了一种用于将基本上管状的聚对苯二甲酸乙二醇酯材料型坯加热至可以双轴拉伸聚对苯二甲酸乙二醇酯材料的所需取向温度的方法。该方法包括以下步骤：通过对其外表面施加热量来加热型坯，直到表面达到低于聚对苯二甲酸乙二醇酯材料开始结晶的温度的最大加热温度，然后冷却型坯的加热外表面以除去来自其中的热量，同时型坯壁内的热量扩散通过其中，从而使相对的内表面的温度朝着期望的取向温度升高。该方法还包括随后的步骤，通过对其冷却的外表面施加热量再加热型坯，直到表面达到不高于最大加热温度的温度，以再次在型坯的壁内加热，然后重新加热再加热的外表面从而再次除去热量，直到型坯壁内的额外热量扩散通过其中，以使相对的内表面的温度进一步提高到大约所需的取向温度，使得通过型坯壁的温度基本上是均匀的从再加热的外表面到相对的内表面。

摘要： A pressure-resistant thermoplastic container has a low center of gravity and a dimensionally stable seating ring zone of substantial strength. The center of gravity is lowered by reducing the weight of the finish and neck, and using a larger diameter for the main body to reduce the overall height while maintaining the desired internal volume. The improved design of the seating ring results in a thicker wall in the bottom end and, therefore, a stronger structure. The bottom end includes a sharp V-shaped structure having a concave inside wall and a generally convex outside wall joined at the bottom ends by a return portion. A convex central portion is connected to an upper end of the inner wall to define a central cavity and an extreme lower end of the outer wall is generally concave.

摘要： A method and apparatus are disclosed for controlling crystallization in thermoplastic materials, such as polyethylene terephthalate, which crystallize when cooled from melt temperature to below glass transition temperature after being injected into a mold cavity. When greater amounts of crystallization are desired, a very high pressure is initially imposed upon the material as it cools from the melt temperature, and then the pressure is reduced proportionally to the reduction in temperature so that a nominal pressure is imposed upon the material at glass transition temperature. When a significantly lesser amount of crystallization is desired, an initial nominal pressure is imposed upon the material as it cools from the melt temperature to a predetermined temperature, at which time the pressure is drastically increased.
