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.

A container capable of being evacuated by a pump which is capable of being removably sealably attached thereto comprising: a cover having a valve mounted therein, said valve adapted for sealing engagement with a removably pump; a container adapted to receive said cover; a deformable indication sealing means positioned between said cover and said container body when said cover is positioned on said container body, said deformable indication sealing means being at least partially directly visible by an observer from outside said container when said container is not properly evacuated; first and second cooperating means defined by said cover and said container body at the interface thereof for retaining said deformable indication sealing means therebetween in an at least a partially visible position as viewed externally of said container by an observer when said container is in a non-evacuated condition; said first and second cooperating means being movable relative to each other when said container is being evacuated, the extent of such movement being dependent on the pressure difference between the interior and the surroundings of said container whereby said deformable indication sealing means is at least partially visible from the exterior of said container when said container is not properly evacuated and said deformable indication sealing means is not directly visible from the exterior of said container when said container is properly evacuated.
