Abstract
The present invention relates to a vacuum sealable container system comprising a container and a lid assembly having a movable valve insert. The valve insert includes a vacuum indicator for informing the user when a vacuum is present in the container. The valve insert is pneumatically movable within a chamber by way of a pump assembly to open and close a fluid communication between the container and the exterior of the container to remove fluid to form the vacuum. The vacuum indicator collapses into an opening formed in the lid assembly to inform the user of the vacuum as well as reinforce the seal formed by the valve insert.
