Abstract
A system for storing articles can have at least two operating modes. In the first mode, gases are evacuated from the system whereby the articles are stored at a pressure less than the pressure at the exterior of the system. In the second mode, gases are evacuated while the system is open to the admittance of gases from the exterior of the system whereby the articles are ventilated by the admitted gases. The system also can have a third operating mode wherein both the first and second modes are rendered inoperative. The storage system can function so that when the articles are stored in the first mode, gases are intermittently removed from the system whereby the pressure at which the articles are stored is maintained at less than the pressure at the exterior of the system. The storage system can be located in a refrigeration appliance such as a household refrigerator.
