摘要

Clamps, systems, and methods for evacuating and hermetically sealing bags having an interior region and an open end. In one embodiment, a clamp includes a first clamp portion having a first chamber portion and a second clamp portion having a second chamber portion. The second clamp portion is movable between a released position and a clamped position. When the second clamp portion is in the clamped position, the first and second chamber portions define a vacuum chamber for removing gas from the bag. The clamp further includes a valve carried by the first or second clamp portion to control the flow of the gas out of the vacuum chamber.
