Abstract

A hair brush comprises a hollow head separable from a handle so that both components can be filled with a hair product. The product can be dispensed through apertures 14 in the head by operation of a plunger 17 arranged to slide axially within the handle on rotation of a screw 13, 16.

Description

DISPENSING BRUSH

This invention relates to a hairbrush, which is capable of dispensing a range of hair products, such as hair gel, directly to the hair or scalp.

Hairbrushes are well know hair-grooming devices that are used by people or on animals. Hairbrushes however do not historically have the capability of assisting the user in applying any hair products to the hair and scalp. In the main, this is generally done by using a persons hands and this results in a more messy and uneven distributed application to the hair.

According to the present invention, a hand-held hollow plastic hairbrush is provided with hollow plastic bristles and holes or ducts in the head of the brush. The handle of the brush is a hollow chamber with an internal screw mechanism that, upon a knob being turned in a clockwise direction at its base, has an internal plug or plunger that moves towards the brush's head. This sliding action of the plug or plunger along the axis of the screw allows the hair product to be pushed forward toward the head of the brush thereby dispensing it via the bristle openings and holes found between the bristles. This brush may be disposable after the hair product is finished or it can be re-filled by unscrewing the handle at the neck and filling the handle and head's now empty chamber.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows in perspective the hairbrush from a side-view of the knob at its base, the neck and the screw on head of the brush with its dispensing bristles and openings between the bristles.

Figure 2 shows the two separate and unscrewed components of the brush. That is, the head and the handle. Figure 3 shows the lateral cross sectional view of the brush thereby illustrating the internal screw mechanism, the chamber of the head and handle for storing hair product, and the plunger for pushing the hair product out of the chambers and onto the scalp or hair.

Referring to figure 1, the hairbrush comprises a hollow head 10 and a screw-on or releasable handle 12.

The Neck 11 is also shown as the point where the handle connects to the head. The Turning Knob 13 is also indicated. The openings or dispensing ducts on the head of the brush between the bristles are shown as 14. The hollow bristles with openings for dispensing the hair product are shown as 15.

Referring to figure 2 we notice that in order to remove the handle 12 and fill it with hair product it is unscrewed at the female neck 11 in an anti-clockwise direction. Once these components are separated, the hair product is inserted into the hollow chamber 18 and re-screwed onto the head at the female neck 11. Referring to figure 3, we take the lateral cross-sectional view of the brush, we identify the internal screw mechanism 16 that has a plug or plunger 17 that moves along its axis. The plunger moves forwards when the knob 13 is turned in a clockwise direction and backwards when it is turned in an anti-clockwise direction. The hairbrush may be supplied full of hair product in which case the plunger is retracted and the chambers in the handle 12 and the head 10 are full. On turning the knob 13 in a clockwise direction, the plunger moves forward in a manner that allows for the product to be dispensed via the bristles 15 and the holes or ducts 14.

When empty the plunger is retracted by turning the knob 13 in an anticlockwise direction thereby creating empty space within the chamber of the handle 18 and the head 19. By unscrewing the handle, it may be re- filled with new product.

Claims

1. A brush that comprises a hollow head and handle in which hair product may be inserted. An internal screw mechanism and plunger allows for this product to be dispensed via bristles and holes found in the head. This is achieved by turning a knob at the base of the handle.

2. A brush as claimed in claim 1 that has a screwable male handle that connects to the base of a female head at the neck.

3. A brush as claimed in claim 1 and claim 2 that has an internal screw mechanism and plunger that moves along an axis in a sliding motion thereby dispensing a hair product.

4. A brush as claimed in claim 1 or claim 2 or claim 3 wherein the purpose is to allow for the easy application of hair products in a clean and evenly distributed manner.

5. A brush as substantially described herein with reference to figures 13 of the accompanying drawings.
