    摘要： This disclosure relates to improvements in the cross section of a bottom end of a plastic bottle suitable for packaging liquids under internal pressures. The bottom end is primarily one which includes a generally hemispherical bottom wall having projecting therefrom in circumferentially spaced relation hollow legs terminating in supporting feet. The bottom end is stiffened against creep of the plastic material over a period of time under the influence of the internal pressure by changing the configuration of the bottom wall from that of a hemisphere to one which includes a configuration of straight line sections and curved line sections when viewed in radial cross section along the axis of the bottle.

    摘要： A container formed of synthetic resinous material having a bottom structure the outer surface of which comprises a central concavity and a convex heel, the heel surrounding the concavity and merging therewith and with the container sidewall. A plurality of hollow convex ribs, distributed in a symmetrical array, interrupt the outer surface of the concavity and merge smoothly therewith, each rib extending longitudinally in the direction of the heel and downwardly from an inner portion of the concavity. The wall of the bottom structure generally decreases in thickness progressively from the innermost point of the concavity to the sidewall.

    摘要： This relates to a blow molding system wherein a plurality of preforms are simultaneously blow molded within a mold set with the preforms being carried by one or more carriers which move first to a loading station to receive preforms, then through an oven to heat the preforms, then into a mold set wherein the plural preforms are simultaneously blow molded, then to an ejection station where the blow molded articles are discharged, and finally back to the loading station. There are two mold sets which are part of a clamp which operates sequentially to open and close each mold set with one mold set being closed as the other mold set is being opened. The carriers may travel either in a single continuous path for sequentially positioning at first one mold set and then the other, or there may be two continuous circuits for the carriers in which event the two mold sets of the clamp may be different. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

    摘要翻译： 这涉及一种吹塑系统，其中多个预成型件在模具组中同时吹塑成型，其中预成型件由一个或多个载体承载，第一个载体首先移动到装载工位以接收预制件，然后通过烘箱加热预制件， 然后进入其中同​​时吹塑多个预成型件的模具组，然后到达吹塑制品排出的喷射站，最后返回到装载站。 存在两个模具组，它们是夹具的一部分，其按顺序操作以打开和关闭每个模具组，其中一个模具组在另一个模具组打开时被关闭。 载体可以在单个连续路径中行进，以便在第一个模具组依次定位，然后另一个，或者可以存在用于载体的两个连续的电路，在这种情况下，夹具的两个模具组可以不同。 本摘要不构成本申请的说明书的一部分，不应被解释为限制申请的权利要求。
