Title: Tint brush with diffuser

Description:
BECKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention is directed to the art of tint brushes and more particularly, to a tint brush that is supplied with hair color dye through a specialized color distributor with diffuser. The tint brush of the invention could be used as an “all purpose” brush as well.  
       [0003] 2. Description of Prior Art  
       [0004] Presently there are several known hair color applicators and hair color dispensers. All of these devices have disadvantages, and are therefore commercially limited. The major problem with these prior dispensers and applicators include outside leakage between roots of bristles by using color mixture. This is primarily flaw of the assembling process which can not be changed. In the process of implantation of the bristles into the tinter body, a wedge like shape of bristles is formed, which in turn causes the creation of small triangular like gaps at the base of the bristles that in turn cause side leakage of the dye. The diffuser overcomes this problem of the dye leakage at the roots of bristles by introducing the dye in an evenly spaced bristle region (gapless region).  
       [0005] It is therefore desirable to have a tint brush with a diffuser that can distribute hair dye mixture evenly throughout all the bristles.  
       SUMMARY OF THE INVENTION  
       [0006] A tint brush with diffuser is provided including hair color dye container adapted for threaded engagement with tinter body with diffuser. Preferably, the tint brush with diffuser screws onto the color distributor.  
       [0007] The bristles are positioned in the grooves of the tinter body, which can be designed with two different diffusers. One type of the diffuser (enclosing diffuser) engulfs/encloses the base of the bristles and another one (nozzle diffuser) that extends to the evenly spaced region of the bristles. Primary object of the invention is to provide a tint brush than enables even and controlled dye mixture diffusion.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0039] FIGS.  1 A- 1 E illustrates the apparatus which includes reusable color mixture container  1  with anatomically shaped body  19  attached to a tinter body  2 . The reusable containers is preferably made of a transparent or semitransparent plastic material such as, PVC or similar, so that the hair dye mixture contained therein can be easily observed and discharged. The container  1  of FIGS. 1A, 1B, and  1 C is adapted to hold a creamer developer, which is combinable with permanent cream colorant. The container  1  is screwed onto the tinter body  2 . The device shown in figures is ready for use in hair dying after preparation of mixture by shaking cream colorant and cream developer in the container  1 . During use of the device, dye mixture flows from the container  1  outward through neck portion  12  and into a damper region  3  defined in the collector chamber  4  of the tinter body  2 . The damper region  3  prevents hydraulic shock when the container  1  is squeezed forcing the dye to exist through radial exit bores  5 . The radial bores  5  are provided with funnel-shaped recess  6  which tangent the set of bristles  9 . The extension member  7  with inside surface  16  encloses the bristles  9  further, the enclosing diffuser prevents dye mixture leakage between triangle like gaps of the bristle roots  17 , and helps deliver continuos and even flow of the dye to the top of the bristles  9 . The extension member  7  is connected onto the tinter body  2  with two teeth  13 , which enter the grooves  14 . The extension member  7  sits on the edge  15  of the tinter body  2 . The circular tooth  8  is formed on the tinter body  2  which seals neck member  12  formed on the container  1 . Needlepoint member  11  is mounted on the front end of the collector chamber  4 . The bristles  9  are stapled into grooves  18 . The bristles  9  are used for application of the dye mixture. Speed of the exiting dye mixture is controlled by squeezing the container  1 . The needlepoint member  11  is adapted to be screwed onto the tinter body  2  and is designed for dividing the hair tufts while dying the hair. The needlepoint  11  is sealed using an O-ring  10 .  
     [0040] FIGS.  2 A- 2 G illustrates the apparatus similar in function and form to that described above in connection with FIGS.  1 A- 1 E with exception that it has a built in flow regulator  29  that includes adjustable head  29 X. The purpose of the flow regulator  29  is to control the flow rate of the dye mixture by turning the adjustable head  29 X. FIG. 2F shows adjustable head  29 X from a position of minimum flow, (marked with a dot)  29 B, to the maximum flow (marked with dot)  29 C. The dot  29 A marks the fixed starting point. The flow regulator  29  is sealed with two O-rings  28  and fixed with retaining ring  22 . The needlepoint  11  has foot spur member  21 , which is located in hole  21 A. The needlepoint  11  has also foot member  26  with cylindrical hole  23 A, which positioned onto spur member  23  with circular member  24  that prevents the needlepoint  11  from disassembly. FIG. 2G illustrates collector body  25 A placed into the neck-connector member  25 C that is secured with teeth  25  in grooves  25 D and sealed with O-ring  28 . Surrounding grooves  27  on the flow regulator  29  are used for the flow regulation. The grooves  27  can have triangle, parabolic or semi-rounded shape, and include a small surface area on one end and taper to a widened cross-sectional area to increase the flow rate to a maximum amount shown in FIGS.  2 D- 2 F.  
     [0041] FIGS.  3 A- 3 G are analogous in form and function to the apparatus described above in connection with FIGS.  2 A- 2 G with exception that the flow regulator  29  is designed together with needle point extension member  21 .  
     [0042] FIGS.  4 A- 4 E shows a tinter apparatus similar to the device discussed above in connection with FIGS.  1 A- 1 E with the exception that the tinter body  2  is made with nozzle diffuser  6 X. The bristle plate  20  is attached onto the nozzle diffuser  6 X, and is secured with two teeth  21 Y. The diffuser&#39;s nozzle  6 X is designed to extend over the triangle like gaps  17  that are formed at the base of the bristle roots  9 . The bristles  9  are stapled into the grooves  18  on the bristle plate  20 .  
     [0043] FIGS.  5 A- 5 G are analogous in form and function to the apparatus described above in connection with FIGS.  2 A- 2 G, with exception that the directed flow of dye mixture is provide with nozzle diffuser  6 X located on the collector body  25 A. Bristle plate  20  is attached onto the nozzle diffuser  6 X with two teeth  21 Y.
