A plastic container is described for liquids which are in part capable of migrating through the plastic. The container has a relatively rigid top and bottom connected by plurality of relatively narrow walls and a plurality of relatively wide wall located between the narrow walls. The wide walls are initially planar but assume a concaved configuration as the pressure in the container is reduced due to migration of moisture through the walls of the container, while the narrow walls rigid top and bottom remain unchanged in configuration.
