Claim:
An integral cap and container assembly comprising: a container having sidewalls, a closed bottom end and opening at an upper end; a cap having a base with an inside surface and an outside surface; a hinge attached to the container and the to the cap at a first end of the cap and a first end of the container to form the integral cap and container assembly; a first selectively permeable membrane that is formed as an integral part of the cap for controlling conditions of gas concentration in an internal portion of the assembly when the cap is closed; a second selectively permeable membrane that is formed as an integral part of the cap for controlling of gas concentration in an internal portion of the assembly when the cap is closed; and a moisture tight resealable configuration formed between the cap and the sidewalls of the container; wherein the first and second selectively permeable membranes are selectively permeable to different gases, the first selectively permeable membrane allows permeation of a first gas and not a second gas, and the second selectively permeable membrane allows permeation of the second gas and not the first gas.
