A vacuum storage system for extending the life of the goods stored therein. The system includes a chamber having an open end, a lid releasably securable to the chamber over its open end and a vacuum adapted for positioning on the lid to evacuate air from within the chamber. The lid has a neck portion with an aperture therethrough and includes a stopper sealably mounted within the aperture and a plug mounted within the stopper for regulating the evacuation of the air within the chamber. The stopper has a channel formed therethrough. The plug has a flared exterior end, an elongated portion and a flared interior end. The elongated portion extends through the channel and has a diameter smaller than the channel's diameter for free movement therein. This allows the vacuum to evacuate air from within the chamber through the channel. The plug's flared exterior end is forced to engage the stopper and seal the channel upon evacuation of the air. The flared interior end engages the stopper and seals the channel to prevent the over evacuation and collapse of the chamber.
