Abstract
A container including a sidewall having a top and bottom ends, a base attached to or proximate the bottom end defining a cavity bounded by the sidewall and by the base, and the base including at least a first portion having a first thickness and a second portion having a second thickness, such that the second thickness is less than the first thickness. A method for controlling deformation in a container including the steps of manufacturing the container as described above, filling the container with a substance, sealing the container at a top end thereof, inverting the container such that the container rests on its top end, allowing the substance to undergo a volume reduction resulting in a vacuum pressure within the container, wherein when subjected to the vacuum pressure, the base deforms at the second portion due to the second thickness being less than the first thickness.
