Abstract

The invention relates to a pressure indicator (6) for a storage container (15) for food. Said container can be closed in an airtight manner and comprises a connecting device (9) for a vacuum pump used to evacuate the air from inside (22) the storage container (15). The invention is characterised in that the pressure indicator (6) is embodied in the form of a dome-shaped membrane which can fold up into itself. One such pressure indicator (6) facilitates the air evacuation process as the user can see immediately when or if there is still a sufficient vacuum inside (22) the storage container (15). The inventive pressure indicator (6) provides an optically and haptically detectable signal corresponding to the pressure state inside the storage container (15).
