ABSTRACT:
A device which is inserted into an opening of a cap, the cap covering a container having powder. When the container or the portion thereof is depressed, a mixture of air and powder on a fine spray is dispensed. The device 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 open at top and bottom ends and having a diameter substantially the same as the third diameter is disposed along the first conduit and constitutes an air tube. The bottom end of the third conduit is disposed above the bottom end of the first conduit and the top end is disposed below the chamber. A fourth inclined hollow conduit having a diameter substantially equal to the third diameter interconnects the third conduit to the chamber to supply air thereto.
