Abstract

A liquid dispensing hair brush includes a body having a chamber therein. The hair brush includes a liquid container in the chamber. A trigger is also contained within the chamber. The trigger may be depressed such that it drives the liquid container relative to the body. A pump is disposed in the container that dispenses liquid from the container through a spray nozzle when the container is driven by the trigger. The pump and container are disposed in the head portion of the brush such that the pump stroke may be relatively short. The container may be removable and replaceable or refillable.

Claims

1. A liquid dispensing hairbrush, comprising:

a body having a chamber;

a liquid container carried by said body inside chamber;

a pump connected to such liquid container;

a spray nozzle carried by said body, said spray nozzle being in fluid communication with said pump;

a plurality of bristles projecting from said body; and

trigger means for moving said pump inside liquid container together as a unit to dispense liquid from said liquid container through said spray nozzle.

2. A liquid dispensing hair brush according to claim 1, wherein said body has a head portion and a handle portion, said spray nozzle being carried by said head portion and said trigger means disposed in said handle portion.

3. A liquid dispensing hair brush according to claim 2, wherein said liquid container is disposed at least partially in said head portion and at least partially disposed in said handle portion.

4. A liquid dispensing hair brush according to claim 2, wherein said trigger means includes a pair of elements pivotally connected to each other and a pusher that abuts said liquid container.

5. A liquid dispensing hair brush according to claim 3, wherein said trigger means includes a resilient trigger movably carried by said body between said body and said liquid container.

6. A liquid dispensing hair brush according to claim 5, further comprising a button carried by said body between first and second positions, said button urging said trigger into said liquid container when said button is in said second position.

7. A liquid dispensing hair brush according to claim 5, further comprising a flexible membrane forming at least a portion of said handle portion, a portion of said flexible membrane disposed adjacent said trigger such that said trigger may be urged against said liquid container by said flexible membrane.

8. A liquid dispensing hair brush according to claim 5 wherein said body includes a base and a handle hingedly attached to said base, said trigger carried in said handle, said trigger being disposed outside said liquid container.

9. A liquid dispensing hair brush according to claim 2 further comprising a delivery pipe disposed between said spray nozzle and said pump, said pump and said liquid container being disposed close to said spray nozzle such that a single pump stroke forces liquid out of said spray nozzle.

10. A liquid dispensing hair brush according to claim 1 wherein said spray nozzle is adjustable.

11. A liquid dispensing hairbrush according to claim 10 further comprising a thumb gear rotatably carried by said body, said thumb gear protruding through said body, said spray nozzle including a plurality of gear teeth disposed on its outer surface, and said thumb gear engaging said gear teeth on said spray nozzle.
