A container capable of being evacuated by a pump which is removably and sealably attached thereto comprises a cover having a removable valve mounted therein and a container body which is adapted to receive the cover. A compressible indication member is positioned between the periphery of the cover and container body, the visibility of which from the outside of the container provides an indication of the evacuation state of the container. The cover and the container body are movable relative to each other which movement is dependent on the pressure difference between the interior and the surroundings of the container whereby the deformation of the indication member provides an indication of the amount of pressure in the container.
