    • An asymmetric pressurized plastic container includes a bottom, a shoulder portion and a finish portion that is unitary with an upper end of the shoulder portion. A generally cylindrical bumper portion having a first longitudinal axis is provided at a lower end of the shoulder portion. A generally cylindrical main body portion having a second longitudinal axis is positioned beneath the bumper portion and has at least a first sidewall feature defined therein. The first and second longitudinal axes are offset so as to compensate for any lateral deflection of the container that may occur as a result of pressurization acting upon the first sidewall feature. In addition, the main body portion may include a second sidewall feature to provide additional compensation against lateral deflection of the container causes a result of pressurization acting upon the first sidewall feature.
    • 不对称加压塑料容器包括与肩部的上端整体形成的底部,肩部和端部。 具有第一纵向轴线的大致圆柱形的保险杠部分设置在肩部的下端。 具有第二纵向轴线的大致圆柱形的主体部分定位在保险杠部分下方并且具有限定在其中的至少第一侧壁特征。 第一和第二纵向轴线被偏移,以便补偿由于作用在第一侧壁特征上的加压而可能发生的容器的任何侧向偏转。 此外,主体部分可以包括第二侧壁特征,以提供抵抗容器的横向偏转的额外补偿,从而导致作用在第一侧壁特征上的加压结果。

    • A method making a plastic container in accordance with one aspect of the present invention includes molding an intermediate container product having a body and a moil integral with the body. The body is of layered construction that includes at least one layer of barrier resin that extends part-way into but not throughout the moil. The upper portion of the moil, in which the barrier material is absent, is removed for recycling as process regrind. The lower portion of the moil is removed to form the container. In the preferred embodiment of the invention, the upper portion of the moil is removed in a laser trimming operation. The lower portion of the moil is removed in the preferred embodiment of the invention by inserting a plug into the open end or mouth of the container, and employing a cutting tool that is positioned by the plug for accurately trimming of the container product with respect to the mouth of the container. The cutting tool preferably is either a pair of shear rollers or a laser cutting tool.
    • 根据本发明的一个方面的制造塑料容器的方法包括模制具有与身体一体的主体和马氏体的中间容器产品。 身体是分层结构,其包括至少一层阻挡树脂,其一部分延伸到整个马尔范围内。 去除阻挡材料的莫尔的上部被去除以作为过程回收再循环。 去除马氏体的下部以形成容器。 在本发明的优选实施例中,在激光修整操作中去除马氏体的上部。 在本发明的优选实施例中,通过将插头插入容器的开口端或口中,并且使用由插头定位的切割工具来精确地修整容器产品相对于 容器的口。 切割工具优选地是一对剪切辊或激光切割工具。
