ABSTRACT:
To enhance evacuation of a storage bag having a one-way valve element and to reduce noise during evacuation, a handheld evacuation device includes one or more gaskets that can be made of resilient material. A gasket can be disposed about the rim of an inlet opening of the evacuation device to provide both a leak-free interface between the evacuation device and the storage bag and to reduce vibration and chatter of the evacuation device against a rigid support surface. A gasket can also be provided intermediately between a main body portion of the evacuation device and a nozzle portion that is to be placed adjacent to the storage bag during use. The intermediate gasket isolates vibrations in the main body portion thereby reducing vibrations and chatter of the evacuation device against a rigid support surface.
