Abstract: A vacuum hand pump and valve system which fits in the palm of a hand and has a deployable crank handle used to turn a vane in order to create a vacuum in a container.

Abstract: A filter for absorbing ethylene gas and moisture and emitting carbon dioxide that can be removably coupled to a container. The container can have vent openings to allow air to circulate to prevent excess condensation, or the container can be any type of flexible, semirigid, or rigid produce container such as a plastic bag, a refrigerator or a typical plastic container. The contents of the filter are in vapor contact with the internal environment of the container such that it can absorb ethylene gas and moisture in the container and release carbon dioxide into the container to retard the ripening process of the produce stored in the container.

Abstract: 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.
