Abstract
A thin walled, plastic hot-fill container has a closable neck, a shoulder portion situated below the neck, a base, and a body portion connecting the shoulder portion to the base. The body portion includes a label mount area bounded by upper and lower margins having a plurality of vacuum panels with vertical land areas separating each adjacent pair of vacuum panels. Each vacuum panel includes an upper area and a lower area, the upper and lower areas of each vacuum panel being mutually asymmetric and connected by a tapering geometry providing a range of pressure response through varying flexibility without significant movement of the components parts of the vacuum panels.
