Abstract
Abstract A powder dispensing brush for use in dispensing medicated powders or flea control powder onto the body of a pet comprises a hollow elongate handle provided with an end opening closed by a snap-lock closure through which the powder is inserted into the handle interior. The handle itself is formed to provide a grasping surface over one longitudinal segment thereof and an applicator segment on the remainder of its structure. Formed on one lateral surface of the applicator segment are a plurality of conical projections each provided with a central vertical port communicating with the interior cavity of the handle. It is through these ports that powder deposited in the handle is dispensed onto the skin of the animal. In order to control the flow rate of the powder there is further included inside the handle a sliding plate provided with a plurality of openings disposed to align, along one point of the sliding stroke with the ports in the projection. This plate may be translated by way of a thumb button extending to the exterior of the handle segment or the grasping segment, thus controlling the rate of powder dispensed.

Claim 1
Independent Claim
304 words
A powder dispenser for use in applying powder by gravity onto the skin of a furry animal as the dispenser is transversely disposed to the animal and moved longitudinally relative to the animal, said powder dispenser comprising: a. an elongate hollow body that includes a top and a bottom, said body including a powder dispensing segment and a handle segment that are coaxially aligned; b. a plurality of longitudinally spaced conical nozzles of varying lengths that project downwardly from said bottom of said dispensing segment, said nozzles having bores extending therethrough that communicate with the interior of said dispensing segment, said nozzles of such length that the free ends thereof are aligned in an arcuate configuration that conforms generally to the transverse convex configuration of said animal's back, both said dispensing segment and handle capable of having said powder stored therein; c. an elongate plate situated in said dispensing segment and slidably supported on said bottom thereof, said plate having a plurality of longitudinally spaced openings therein that are axially aligned with said bores in said nozzles when said plate is moved from a first to a second position in said dispensing section, with powder in said dispensing section falling by gravity through said openings and bores to be dispensed onto the fur of said animal when said plate is in said second position and said body is moved longitudinally relative to the body of said animal; d. articulating means connected to said plate and extending to the exterior of said body for moving said plate to either said first or second position, said openings and bores being out of communication when said plate is in said first position, and said powder being maintained within said body, said articulating means including: 1. an elongate spline secured to said plate and extending upwardly therefrom; 2.
