ABSTRACT:
Hand-held and hand-operable powder dispenser having a container including a handle
ozzle section terminating at its discharge end in an unobstructed powder dipensing opening, a hand gripping section, and a central, flexible bellows section coupled between the handle
ozzle section and the hand-gripping section. The bellows section is adapted to be collapsed and expanded axially to serve as a pump. The inside diameters of the handle
ozzle section decrease substantially linearly and continually as a function of the length of the handle
ozzle section in a direction toward the powder dispensing opening. The ratio of the length of the handle
ozzle section to the greatest value of its inside diameter is substantially greater than 1.4.
