ABSTRACT:
A device for use in a powder entraining squeeze container employs a first vertical hollow circular conduit having a first diameter, open at top and bottom ends and constituting a dip tube. A hollow spherical chamber having a second and much larger diameter and constituting an air powder mixing chamber is disposed above the dip tube, the top end of the dip tube being connected to the bottom of the chamber. A second vertical hollow conduit having a third diameter smaller than the first diameter is secured at its open bottom end to the top of the chamber and is used to discharge the mixture from its top open end. A third vertical hollow conduit in the chamber wall is open at top and bottom ends and is disposed alongside of a portion of the first conduit. The diameter of the third conduit is substantially equal to the third diameter. The open top of a vertical hollow cup closed at its bottom is spaced below the chamber. The cup has a cylinder extending upward from the bottom of the cup to receive the bottom end of the first conduit, this cylinder having a bore which communicates with the interior of the first conduit. The cup bottom has an opening communicating with the bore.
