ABSTRACT:
A vacuum assembly for recovering and dispensing flowable packaging material is comprised of a chamber, an air pump, a screen, and a handle. The air pump, which may be an electric motor and squirrel cage blower, is stationed to pump air into the mouth, through the chamber, through the screen, and out an exhaust where the air may be useful for blowing flowable packaging material. The screen may be contoured or flat, and is configured to allow the passage of air but not the passage of flowable packaging material. The mouth opens to the exterior of the vacuum assembly, and is configured such that flowable packaging material that is contained within the chamber can fall out of the mouth, under the influence of gravity, when the mouth is oriented downward and the air pump is not pumping air. The chamber may increase in cross-sectional area from the mouth to the screen. A door, flap or other shutting mechanism may be used to shut the mouth. The chamber may be shaped to be seated in a container such that the vacuum assembly may be rested in a raised opening in the chamber.
