Abstract
A food bag closure assembly includes a clip that has a pair of jaws being biased against each other for closing an opened food bag. A gas unit is provided that stores an inert gas and the gas unit is integrated into the clip. The gas unit is in fluid communication with an interior of the food bag when the clip is positioned on the food bag. Moreover, the gas unit is actuated to release a pre-determined volume of the inert gas each time the clip is closed. In this way the gas unit injects the inert gas into the food bag for extending the shelf life of food contained in the food bag.
