    • A plastic container that is adapted for adjustment to internal volumetric changes includes a container body defining an internal space and having a main body portion that defines a longitudinal axis and an outer diameter. The main body portion is substantially cylindrical at its outer diameter, and includes first and second recessed flexible vacuum uptake panels, each of which is constructed and arranged to flex inwardly to provide vacuum uptake when a sufficient underpressure exists in the internal space relative to ambient external pressure. The main body portion further includes a front side defining a first curved sidewall portion between the first and second recessed panels and a rear side defining a second curved sidewall portion between the first and second recessed panels. The first curved sidewall portion has a length L1 as viewed in horizontal cross-section that is less than a length L2 of the second curved sidewall portion. Each of the recessed panels has an upper portion and a lower portion, and each recessed panel is tapered so that the upper portion is recessed with respect to the outer diameter to a greater extent than the lower portion is recessed with respect to the outer diameter. This optimizes the usable surface area of the vacuum panels and forms a tapered grip configuration that enhances grippability of the plastic container by consumers.
    • 适于调整到内部体积变化的塑料容器包括限定内部空间并具有限定纵向轴线和外径的主体部分的容器主体。 主体部分在其外径处基本上是圆柱形的,并且包括第一和第二凹陷的柔性真空吸收板,每个板被构造和布置成向内弯曲以在内部空间中相对于环境外部存在足够的负压时提供真空吸收 压力。 主体部分还包括限定第一和第二凹陷面板之间的第一弯曲侧壁部分的前侧和在第一和第二凹陷面板之间限定第二弯曲侧壁部分的后侧。 第一弯曲侧壁部分具有在水平横截面中看到的长度L1,其小于第二弯曲侧壁部分的长度L2。 每个凹陷板具有上部和下部,并且每个凹形面板是锥形的,使得上部相对于外径相对于外径凹陷的程度大于下部。 这样可以优化真空面板的可用表面积,并形成锥形夹持构造,从而提高消费者对塑料容器的抓握性。

    • A blow molded plastic container for hot fill and pasteurization uses includes a main body portion that is shaped so as to be substantially rectangular in horizontal cross-section and a base portion. The base portion is shaped to define a generally rectangular standing ring and an elevated push-up portion that is positioned radially inward of the standing ring. The push-up portion includes a central region, an annular, substantially straight and substantially vertical rise portion that is positioned immediately radially inward of the standing ring and a plurality of radially oriented waves. Each of the waves extends radially outwardly from the central region to the vertical rise portion. The main body portion is shaped so as to have a plurality of sidewall portions that are bounded by a plurality of vertically extending edge portions. In one embodiment, at least one of the vertically extending edge portions may have at least one inwardly extending gusset defined therein to provide structural reinforcement.
    • 用于热填充和巴氏杀菌用途的吹塑塑料容器包括形状为水平横截面为大致矩形的主体部分和基部。 基部被成形为限定大致矩形的立环和位于立环的径向内侧的升高的上推部分。 上推部分包括中心区域,环形的,基本上直的和基本上垂直的上升部分,其立即位于立环的径向内侧,以及多个径向定向的波。 每个波从中心区域径向向外延伸到垂直上升部分。 主体部分成形为具有由多个垂直延伸的边缘部分限定的多个侧壁部分。 在一个实施例中,垂直延伸的边缘部分中的至少一个可以具有限定在其中的至少一个向内延伸的角撑板以提供结构增强。
