The present invention is directed to an apparatus to store matter out of contact with gas. A container for storage of matter is combined with a vacuum pump for extracting gas from the container. The vacuum pump has an inlet tube in which is arranged a sealing means for locking the inlet tube and thereby preventing re-entry of gas into the container after the gas has been exhausted by the vacuum pump therefrom, and during storage. The lockable sealing means may be arranged on the inlet valve of the vacuum pump, or it may be internally located in a probe serving as the inlet tube of the vacuum pump and inserted through the container's gas tight sealing means, such as the interlocking strip closure of a food storage bag. In both instances the locking means is operated by external force. In the case where the vacuum pump is of the Venturi type, the combination incorporating the probe is employed and the probe is pinched at the area of the internal sealing device to lock the probe closed against re-entry of the gas into the container after gas-exhaustion from the container has been completed. The types of vacuum pumps employed in the embodiment of this invention include separate pumps which may be re-used in combination with other containers, or which are molded integrally with or affixed to the container.
