    摘要: 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.

    摘要: 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.
