BRUSH FOR APPLYING LIQUID OR EMULSION MATERIAL 8 401 3 BACKGROUND OF THE INVENTION

The present invention relates to a brush for applying a liquid or emulsion material having a container containing a material such as a toothbrush material, a hair dye, a hair growth agent, a hair styling agent, a dye, a cleaning agent, a lubricating oil, etc. in a liquid or emulsion form.

A variety of brushes are designed to apply liquid or emulsion material. For example, there are toothbrushes that contain a toothbrush agent in the form of a paste or emulsion and feed the agent to their bristle portion when used in toothbrushing operations. In the toothbrushes disclosed in Japanese Utility Model Publication Nos. 158966/1977 and 102574/1979, the material on their handle is pushed out by ejection parts such as a piston or the like. However, the operation of pushing out the material is cumbersome, and it is difficult to fit the piston or other to push out the necessary amount of material. In a toothbrush of the type which includes a toothbrush ejection mechanism in the handle, there is not much space left for the material. If a toothbrush is used, the substance will run out before the part comprising the bristles becomes unusable and refilling of the substance is necessary. In addition, the closure has not been made completely between the interior of its handle and the part comprising the bristles. Thus, there has been a case where the substance flows back into the interior of the handle from the user's mouth during the toothbrushing operation. As described above, conventional toothbrushes containing toothbrush material have these several disadvantages.

Further, there have been brushes of the type having a handle to which a large number of bristles are attached at the front to project radially from the front. When the user uses the brush to color their hair, he pours the hair dye into the bristles from the hair dye bottle to apply the hair dye to his hair while brushing his hair with the brush.

2 8401 3 In this coloring operation, it is difficult for the user to pour a predetermined amount of hair dye into the brushes of the brush. Sometimes he pours hair dye more or less than the necessary amount into the bristles, thus causing uneven coloring.

Besides, when a user applies hair growth medicated liquid or hair styling medicated liquid to his hair or scalp, he pours some amount of medicated liquid on his palm from the bottle where it is, to brush it on his hair with his hand, or he pours an amount of medicated liquid on his hair directly from the bottle to brush it on his hair. In this application, the user's hand becomes dirty.

DETAILED DESCRIPTION OF THE INVENTION

In Figures 1 to 3, the brush 1 according to the present invention comprises a handle 2 and an arm 3 in which bristles are arranged and which are axially slidable at the front end of the handle 2, the handle 2 having a pumping mechanism 4 for hair color of a material such as a toothbrush. , for feeding hair growth agent, hair lotion, cleaning agent, dyes, lubricating oil, etc. in liquid or emulsion form.

The handle 2 comprises in combination a main body 5 and a material container 6 with liquid or emulsion material 24 connected to the handle body 5. The container 6 has an external thread 6A predominantly on its protruding circumferential surface, and the main body 5 has an internal thread 5A on the rear inner circumference. The body 5 and the container 6 are releasably connected to each other by a screw thread, the external thread 6A and the internal thread 5A.

The arm 3 comprising bristles is formed at its ends into a uniform rectangle with a cross-section like a normal brush. The bristles 7 are placed on the bristle placement surface 3A at the end of the arm 3. The arm 3 has a passage 8 of material in its inner part from the rear end 3B to the bristle part 3A. The passage 8 opens directly to the surface 3A comprising the bristles or communicates with the placement holes of the respective bristles 7 placed on the bristle placement surface 3A, so that the material 24 can seep into the roots of the bristles 7.

The arm 3 is slidably fitted from its part 3B to the bearing part 9 of the body 5 to maintain the closing action between the root part 3B and the inner circumferential surface of the bearing part 9. The bearing part 9 has a groove 10 which extends axially on the circumferential surface of the bearing part 9. The functional protrusion 11 protrudes from the outer circumferential surface of the root portion 3B of the stem 3. The protrusion 11 slidably engages the groove 10, preventing the arm 3 from rotating about its axis. The functional protrusion 11 is provided with a non-slip surface 11A, which is roughened in order to prevent the thumb of the user's hand from slipping out of it. The protrusion 11 and the groove 10 form an anti-rotation means. The pumping mechanism member 4 is a functional pipe 12, which is integral with the valve part 15 on the outer circumferential surface of the pipe 12. The valve portion 15 has a front and a rear edge portion 15A and 15B, respectively. The front edge portion 15A acts to prevent air or dirty water from entering and penetrating the main body 5 through the sliding portions of the bearing portion 9, while the rear edge portion 15B acts to prevent material from leaking out. The front surface of the valve part 15 is adapted to abut against a protrusion 30 on the inner surface of the main body 5 of the hand position 2 when the tube 12 is in the normal position.

The front part of the tube 12 is fitted in an opening 31 formed in the root part 3B of the arm 3. A front valve body 19 is arranged in front of the pipe 12, the shape of which is shown in Figures 8 and 9. * The valve body 19 is made of a flexible material such as synthetic resin. Further, the valve body 19 has two valve plates 19A and 19B at its front and rear ends, respectively. The valve plate 19A generally has the shape of a circle, the circumference of which is partially cut to form four passageways 19D for the passage of material. The second valve plate 19B, which is similar in shape to the plate 19A, has four passages 19D. The two valve plates 19A and 19B are connected to each other by a ring portion 19C, which mainly functions as a flexible part. The valve body 19 is fitted in the opening 31 in a position where the circumferential portion of the front valve plate 19A abuts a shoulder 3C formed on the inner surface of the opening 31.

The front surface of the functional tube 12 has an annular protrusion 12A which engages the rear valve plate 19B. The pipe 12 is located in the connection area of the root part 3B of the stem 3 and the main body 5 and has a channel 32 extending longitudinally for feeding material 24 from the airtight suction chamber 21 to the stem 3 · The suction chamber 21 is formed between the valve part 15 and the valve housing part 16 is attached to the rear end of the body 5.

The spherical rear valve body 20 is fitted to the valve housing portion 16. The rear valve body 20 is made of steel. A functional rod 22 is freely fitted in the channel 32 to control the movements of the front valve body 19 and the rear valve body 20. The valve housing part 16 is cup-shaped and has a suction opening 18 at the bottom.

7 84013

The inner wall of the valve housing portion 16 has a large number of stops 16B. The stops 16B are placed at predetermined distances circumferentially in the valve housing portion 16. The stops 16B form a space 33 for accommodating the rear valve body 20, and each stop 16B has a protrusion 16C at its front end to prevent the valve body 20 from exiting the space 33.

The rear half of the functional tube 12 continues into the suction chamber 21. A compression coil spring 17 is mounted to force the tube 12 forward and is positioned between the front surfaces of the stops 16B and the bellows valve portion 15 where the rear half of the tube 12 is inserted into the coil spring 17.

The above-mentioned functional rod 22 is thin enough so as not to block the material 24 along the flow channel 32 in the pipe 12 and is slightly shorter than the distance of the two valve bodies 19 and 20 in the state where the valve body 19 closes the channel 32 and the valve body 20 closes the opening 18, as shown in Figure 3.

The bottom of the container 6 is provided with a piston-like movable base body 23 which is axially slidably in close contact with the inner circumferential surface of the container 6. The movable base body 23 is made of a soft synthetic resin or the like, and has pushing edges 23B and 23C which expand into a clock shape, respectively, the advantages of the cylindrical portion 23A at the rear end. The tight contact of the pushing edges 23B and 23C with the inner circumferential edge of the container ensures airtightness, so that the emulsified material or liquid material 24 filled in the container 6 cannot leak out.

The front end of the cylindrical portion 23A has a smaller diameter cylindrical portion 231) that can be inserted into the protruding, smaller diameter portion 6B at the mouth of the container 6 so that the material 24 can be used completely. In the drawings, reference numeral 25 denotes a base plate 8 84013 which prevents the movable base body 23 from falling off the rear end of the container 6. The base plate 25 is inserted into the circumferential surface of the opened rear end of the container 6. At the same time, the base plate 25 acts as a reinforcing member which prevents the container from deforming under the influence of external forces, for the purpose of maintaining close contact at the sliding edges 23B and 23C with the interior of the container. The base plate 25 has a rod 25 projecting in the center, which extends into the cylindrical part 23D of the base body 23, limiting the rearward movement of the base body 23. The base plate 25 has a large number of air passages 25B which prevent the air pressure from becoming negative in the rear space 34, which is limited by the base body 23 and the base plate 25 when the base plate 25 is moved forward during use of the brush 1.

The operation of the brush 1 will be explained with reference to Figures 3 to 7.

The handle 2 is held with one hand in the position shown in Fig. 3. When the brush 1 is used, the arm 3 comprising the bristles is pushed backwards or towards the container 6 by placing a thumb on the functional projection 11, pushing the tip of the arm 3 with one hand or pressing the tip of the arm 3 against something. The rear part of the arm 3 is pushed into the handle 2 along the bearing part 9, as shown in Fig. 4, and the functional tube 12 is pushed into the handle main body 5 ·

When the arm 3 is inserted into the handle 2, as shown in Fig. 4, the functional tube 12 moves rearwardly and the front end of the functional rod 22 abuts the valve plate 19B, causing the valve body 19 to collapse or crumple so that the front opening of the passage 32 opens. thus tightly closing the suction opening 18.

The arm 3 is then released from the push, thus causing the compression spring 17 to push back, to push the arm 3 9 84013 and the tube 12 to the respective front positions. In this case, the pressure in the opening chamber 21 of the body 5 becomes negative, and as a result the material 24 in the container 6 is absorbed into the suction chamber 21 of the body 5 through the suction opening 18 of the valve housing part 16 (Fig. 5).

When the valve part 15 is slid forward, the leading edge part 15A is forced to expand in the radial direction, whereby close contact with the inner circumferential wall of the body 5 is achieved. Furthermore, the front valve body 19 closes the tank 32. Thus, no air or dirty water enters or penetrates the suction chamber 21 when it is in a negative pressure state through the openings of the sliding parts of the bearing part 9. The suction causes a negative pressure on the container 6, causing the movable base body 23 to move for a short distance in close contact with the inner circumferential wall of the container 6.

The arm 3 is pushed back again as described above. In this case, the front valve body 19 opens the channel 32 of the pipe 12 and the rear valve body 20 closes the suction opening 18 in the valve housing part 16. The material sucked into the suction chamber 21 is fed into the opening 31 and the material passage 8 of the stem 3 (Figure 6). Thereafter, the arm 3 is released from the push and the material 24 in the suction chamber 21 ceases to flow forward and the material 24 in the container 6 is absorbed from the container 6 into the suction chamber 21 of the body 5 (Fig. 7). As described above, this suction causes the movable bottom body 23 in the container 6 to move forward corresponding to the amount of material sucked 24.

When the brush 1 is initially used, this operation is repeated two or three times to fill the body 5, the channel 32 and the material passage 8 with material 24. Thereafter, one push of the arm 3 feeds an amount of material suitable for one operation onto the bristle surface 3A. Thus, the brush 1 is ready for use. Individually, if the amount of material 24 fed to the surface 3A is not sufficient, it can be pushed twice or more.

10 84013

When the material 24 in the container 6 is exhausted, the container 6 is unscrewed from the rear end of the body 5, the lid (not shown) screwed into the new container 6 with an external thread is removed, and the new container external thread 6A is attached to the body 5 internal thread 5A. Then immediately the brush can be used continuously again.

When the opening of the material passage 8 opening to the bristle surface 3A of the shaft 3 can become dry during continuous use, the entire brush portion 7 can be covered with the cover 26, as shown in Fig. 1 by dotted lines.

According to the present invention, the functional rod 22 is located between the front and rear valve bodies 19 and 20, controlling the opening and closing movements of the two valve bodies 19 and 20. The rod 22 can ensure reliable optional movement of the two valve bodies, as shown in Figures 4-7. Further, if the length of the rod 22 is suitably set, the necessary supply of material 24 to the surface 3A can be ensured.

Moreover, since the front valve body 19 is a resilient valve member that can shrink and expand itself, a special coil spring to force the valve body against the opening of the pipe 12 is not necessary, and thus the structure of the valve mechanism becomes simple.

As described above, the brush 1 of the present invention comprises an arm 3 in which bristles are placed, the arm having a functional protrusion 11, and when the arm is pushed against the main body 5, it can supply a certain amount of material 24 to the bristle surface 3A. Preferably, this allows the brush to be used with a single operating contact. Moreover, when one push of the arm 3 pushes a predetermined amount of material, the user does not have to pay attention to how much material should be compressed into one operation, as is usually the case in operation, and wastage of moving material can be avoided. Furthermore, the material 24 is fed simply by pushing 11 84013 4 the arm 3 · Thus, when the brush is used as a toothbrush, even infants and children can easily use the brush 1. In addition, the material container 6 is easily detachable from the main body 5 and disposable, and preferably the main body 5 of the brush can be used for a long time.

In particular, in the brush 1 according to the present invention, the movable bottom body 23 moves forward in response to the reduction of material 24 in the container 6 when the arm 3 is pushed back to feed the material 24 against the arm 3. This completely prevents air from being absorbed from the outside into the material 24 in the container 6. For hygienic reasons, it is desirable that the material can be fed in a completely enclosed space. Among other things, the brush 1 according to the invention comprises a small number of parts and is easy to manufacture.

In the embodiments described above, a large number of fine or thick bristles are placed at the end of the shaft 3 to apply the material 24. However, instead of bristles, a piece of sponge, a piece of rubber or a part with a convex-concave surface can be attached to the end of the shaft 3 to apply the material.
