    • A plastic container that particularly adapted for hot-fill applications includes a bottom portion; and a sidewall portion that is unitary with the bottom portion. The sidewall portion has a maximum outer diameter, and includes first and second pairs of opposing first and second vacuum panels, respectively. At least one of the second vacuum panels includes gripping structure. The first and second vacuum panels respectively have first and second substantially constant radii of curvature as measured in a horizontal plane that are substantially constant from upper to lower ends of the vacuum panels. At least one of the second vacuum panels may be asymmetric about a central vertical axis as viewed in side elevation.

    • A plastic container that is adapted for adjustment to internal volumetric changes such as those that occur as a result of internal pressure and temperature changes during the hot-fill process includes a container body defining an internal space. The container body has at least one flexible panel defined therein, which includes an outer flexible panel portion and an inner flexible panel portion. The outer flexible panel portion has a shape when a pressure equilibrium exists between the internal space and ambient external pressure, and is further constructed and arranged to assume a shape of increased concavity when a sufficient underpressure exists in the internal space. The inner flexible panel portion is constructed and arranged to flex relative to the outer flexible panel portion in order to accommodate internal pressure changes within the container body. The inner and outer flexible panel portions accordingly work in tandem to permit efficient vacuum uptake in a hot-fill type container. In addition, a boundary between the outer and inner flexible panel portions is preferably entirely curved.
    • 适于调节内部体积变化的塑料容器,例如在热填充过程中由于内部压力和温度变化而发生的体积变化,包括限定内部空间的容器主体。 容器主体具有限定在其中的至少一个柔性面板,其包括外部柔性面板部分和内部柔性面板部分。 外部柔性面板部分在内部空间与周围外部压力之间存在压力平衡时具有形状,并且当在内部空间中存在足够的负压时,进一步构造和布置成呈现增大的凹度的形状。 内部柔性面板部分构造和布置成相对于外部柔性面板部分弯曲,以便容纳容器主体内的内部压力变化。 内部和外部柔性面板部分相应地串联工作以允许在热填充型容器中有效的真空吸收。 此外,外部和内部柔性面板部分之间的边界优选是完全弯曲的。

The sidewall portion has a maximum outer diameter, and includes first and second pairs of opposing first and second vacuum panels, respectively. At least one of the second vacuum panels includes gripping structure. The first and second vacuum panels respectively have first and second substantially constant radii of curvature as measured in a horizontal plane that are substantially constant from upper to lower ends of the vacuum panels. A ratio of the first substantially constant radius of curvature to the maximum outer diameter is within a range of about 0.3 to about 2.5, and a ratio of the second substantially constant radius of curvature to the maximum outer diameter is within a range of about 0.2 to about 2. At least one of the second vacuum panels may be asymmetric about a central vertical axis as viewed in side elevation.
