    摘要： An improved one-piece plastic container of the champagne base variety having an annular peripheral chime surrounding an inward sloping base portion for containing carbonated beverages and associated methods for making same by blow molding. The preform defining interior and exterior walls which are ever decreasing in diameter from the neck to the base so that the preform may be easily removed from a mating core and injecting mold cavity used therewith thereby avoiding the need for a split mold to form the preform. In a blow molding process for producing a one-piece plastic container by expanding an elongated preform containing plastic material for the neck, body and base of the container in a mold, the process for forming a container of the champagne base variety comprising the steps of forming the preform on a core rod with annular thickened portions of the preform positioned at points along the length thereof such that during blowing of the preform the material of the preform will be deposited where desired; positioning the preform within a blow molding cavity defining the finished container shape; extending a stretch rod within the preform towards the bottom of the blow molding cavity, prior to injection of pressurized gas, to longitudinally stretch a sidewall-forming portion of the preform while minimizing stretching of a base-forming portion thereby inducing the base-forming portion to lay down where desired when injected with pressurized gas; and injecting pressurized gas into the preform adjacent the neck whereby the preform is radially stretched outward to fill the cavity and form the container from the neck towards the base.

    摘要： An improved one-piece plastic container of the champagne base variety having an annular peripheral chime surrounding an inward sloping base portion for containing carbonated beverages and associated methods for making same by blow molding. The preform defining interior and exterior walls which are ever decreasing in diameter from the neck to the base so that the preform may be easily removed from a mating core and injecting mold cavity used therewith thereby avoiding the need for a split mold to form the preform. In a blow molding process for producing a one-piece plastic container by expanding an elongated preform containing plastic material for the neck, body and base of the container in a mold, the process for forming a container of the champagne base variety comprising the steps of forming the preform on a core rod with annular thickened portions of the preform positioned at points along the length thereof such that during blowing of the preform the material of the preform will be deposited where desired; positioning the preform within a blow molding cavity defining the finished container shape; extending a stretch rod within the preform towards the bottom of the blow molding cavity, prior to injection of pressurized gas, to longitudinally stretch a sidewall-forming portion of the preform while minimizing stretching of a base-forming portion thereby inducing the base-forming portion to lay down where desired when injected with pressurized gas; and injecting pressurized gas into the preform adjacent the neck whereby the preform is radially stretched outward to fill the cavity and form the container from the neck towards the base.

    摘要翻译： 一种改进的香槟酒品种的单件塑料容器，其具有围绕用于容纳碳酸饮料的向内倾斜的基部的环形周边钟，以及通过吹塑成型制成相同的方法。 该预成型件限定了内部和外部壁的直径从颈部到底部的直径减小，使得预成型件可以容易地从匹配的芯部移除并注入与其一起使用的模腔，从而避免了分割模具形成预成型件的需要。 在用于通过将容纳物的颈部，主体和基底的塑料材料膨胀的细长预成型件在模具中生产单件塑料容器的吹塑成型方法中，形成香槟基料种类的容器的方法包括以下步骤： 在预成型件的芯棒上形成预成型件，其中预成型件的环形加厚部分位于沿其长度的点处，使得在吹塑预制件期间，预成型件的材料将在需要的地方沉积; 将预成型件定位在限定最终容器形状的吹塑模腔内; 在注射加压气体之前，将预成型件内的拉伸杆朝向吹塑空腔的底部延伸，以纵向拉伸预成型件的侧壁形成部分，同时使基部形成部分的拉伸最小化，从而引起基底形成部分 在注入加压气体的情况下放置在需要的地方; 并且将加压气体注入邻近颈部的预成型件中，由此预制件向外径向拉伸以填充空腔并从颈部朝向基部形成容器。
