Abstract
A plastic container, sidewall portions, and method of same are described. The sidewall portion can accommodate a vacuum in a filled and sealed container and includes a plurality of columns extending between upper and lower ends of the sidewall portion, and a plurality of vacuum panels oriented vertically between respective adjacent ones of the columns, each vacuum panel including an upper section, a middle section, and a lower section, a first hinge connecting the upper and middle sections, and a second hinge connecting the middle and lower sections. The vacuum panels can move radially inward toward a container central axis such that the container vacuum is accommodated. As the vacuum panel moves radially inward, the middle section can maintain a substantially parallel orientation with respect to the central axis, and the upper and lower sections rotate about first and second hinges, respectively, and incline away from the central axis.
