Abstract
Abstract 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.

Dependent Claim
6 words
A liquid disposed within the container;
Claim 21
Dependent Claim
6 words
A liquid disposed within the container;
Claim 22
Dependent Claim
54 words
Said top, bottom and walls being formed from a plastic which is permeable by said liquid; whereby the relatively wide wall portions become concaved when the liquid migrates through the plastic and the internal pressure becomes less than the ambient pressure while the relatively narrow wall portions, top and bottom, retain their initial shape.
Claim 23
Dependent Claim
