Definitions

  • This invention relates to a brush for applying liquid or emulsion material, having a container for containing material such as tooth-brushing material, hair-dye, hair-growth material, hair-dressing material, paints, cleaning material, lubricating oil, etc. in liquid or emulsion form.
  • toothbrushes which contain therein tooth- brushing material in paste or emulsion form and feed the material onto their bristle-planted portions when they are used for tooth-brushing operations.
  • the material contained in their handles is extruded by extrusion members, such as a piston, or others.
  • extrusion members such as a piston, or others.
  • the operation for extruding the material is troublesome, and it is difficult to adjust the piston or others so as to extrude a necessary amount of the material.
  • a toothbrush of the type which contains a tooth-brushing material extrusion mechanism in its handle much space is not allowed for the material.
  • the toothbrush If the toothbrush is made disposable, the material runs out before its bristle-planted portion becomes unusable, and it is inevitable to make the material refillable. Additionally the sealing is not carried out perfectly between the interior of its handle and the bristle-planted portion. Accordingly there has been a case wherein the material flows back into the interior of the handle from its user's mouth during the tooth-brushing operation. As described above, the conventional toothbrushes containing tooth-brushing material have these various drawbacks.
  • a user uses the brush to dye his hair, he pours hair-dye on the bristles from a bottle containing the hair-dye to apply the hair-dye on his hair while rubbing his hair with the brush.
  • liquid or emulsion material such as toothpaste, hair-dye, etc.
  • a brush for applying liquid or emulsion material comprising a handle having a container for containing material in liquid or emuslion form and a main body, rod provided, at its head, with a great number of bristles, a piece of sponge, a piece of rubber or likewise members and a pumping mechanism provided in the handle for sucking the material from the container and feeding the sucked material to the head of the rod, characterized in: that a rear end of the main body of the handle is connected detachably to a mouth of the container; that the root portion of the rod is inserted axially slidably into a forward bearing portion of the main body in such a manner that rotation of the rod can be avoided by a rotation-preventing-means and the rod has a material feeding passage extending from the root portion to the head thereof; and that the pumping mechanism is operated in accordance with axial movements of the rod at the time when the rod is pushed rearward and thereafter returned forward and the pumping mechanism comprises (i) an operational pipe
  • a brush 1 of this invention comprises a handle 2 and a bristle-planted rod 3 inserted in the forward end of the handle 2 slidably axially thereof, the handle 2 housing a pumping mechanism 4 for feeding material such as tooth-brushing material, hair-dye, hair-growth material, hair-dressing material, cleaning material, paints, lubricating oil, etc. in liquid or emulsion form.
  • the handle 2 comprises a combination of a main body 5 and a material container 6 for housing a liquid or emulsion material 24, connected to the handle body 5.
  • the container 6 has a male thread 6A- provided in the projected peripheral surface of the forward end thereof, and the main body 5 has a female thread 5A provided in the inside peripheral surface of the rear portion thereof.
  • the body 5 and the container 6 are connected detachably to each other by the screw-engagement of the male thread 6A with the female thread 5A.
  • the bristle-planted rod 3 is formed at its head, in a flat shape of rectangular section like a common brush.
  • the bristles 7 are planted in a bristle-planted surface 3A of the head of the rod 3.
  • the rod 3 has a material passage 8 provided in the interior thereof from the rear end 3B to the bristle-planting surface 3A thereof.
  • the passage 8 opens directly on the bristle-planting surface 3A or is in communication with the planting holes of the respective bristles 7 planted in the bristle-planted surface 3A so that the material 24 can be exuded at the roots of the bristles 7.
  • the rod 3 is slidably inserted at the root portion 3B thereof into the bearing portion 9 of the body 5 so as to keep a sealing function between the root portion 3B and the inside peripheral surface of the bearing portion 9.
  • the bearing portion 9 has a slit 10 extending axially in the peripheral surface of the bearing portion 9.
  • An operational projection 11 is protruded from the outside peripheral surface of the root portion 3B of the rod 3.
  • the projection 11 is engaged slidably with the slit 10 to prevent the rod 3 from rotating about its axis.
  • a slip prevention surface 11A which is rugged in order to prevent a thumb of a user's hand from slipping thereon.
  • the projection 11 and the slit 10 form rotation-preventing means.
  • the pumping mechanism 4 has an operational pipe 12 which is integrally provided with a valve portion 15 at the outer peripheral surface of the pipe 12.
  • the valve portion 15 has front and rear lip portions 15A and 15B, respectively.
  • the front lip portion 15A functions to prevent air and dirty water from entering and permeating into the main body 5 through the sliding portions of the bearing portion 9 while the rear lip portion 15B functions to prevent the material from leaking out.
  • the front surface of the valve portion 15 is adapted to abut against a projection 30 provided on the inner surface of the main body 5 of the handle 2 when the pipe 12 is in a normal position.
  • the front part of the pipe 12 is inserted into a hole 31 formed in the root portion 3B of the rod 3.
  • a forward valve body 19 which has a shape shown in Figs. 8 and 9.
  • the valve body 19 is made of elastic material such as synthetic resin.
  • the valve body 19 has two valve plates 19A and 19B at its front and rear ends, respectively.
  • the valve plate 19A has, in general, a circular shape whose peripheral is partially cut to form four paths 19D for passing the material.
  • Another valve plate 19B of the same shape as the plate 19A has four paths 19D.
  • the two valve plates 19A and 19B are connected to each other by a loop portion 19C mainly functioning as an elastic member.
  • the valve body 19 is accommodated in the hole 31 in a state wherein the peripheral portion of the front valve plate 19A abuts against a step 3C formed on the inner surface of the hole 31.
  • the front face of the operational pipe 12 is provided with an annular projection 12A which engages with the rear valve plate 19B.
  • the pipe 12 is provided in a connecting region of the root portion 3B of the rod 3 and the main body 5 and has a conduit 32 extending in its longitudinal direction in order to feed the material 24 from an airtight suction chamber 21 to the rod 3.
  • the suction chamber 21 is formed between the valve portion 15 of the pipe 12 and a valve seat member 16 fixed to the rear end of the body 5.
  • a ball-shaped rear valve body 20 is accommodated in the valve seat member 16.
  • the rear valve body 20 is made of steel.
  • an operational bar 22 for controlling the movement of the forward valve body 19 and the rear valve body 20.
  • the valve seat member 16 is cup-shaped and its bottom has a suction hole 18.
  • libs 16B On the inner wall of the valve seat member 16 are provided a plurality of libs 16B.
  • the libs 16B are disposed at a predetermined distance in the circumferential direction of the valve seat member 16.
  • the libs 16B form a space 33 for accommodating the rear valve body 20 and each lib 16B has a projection 16C, at its front end, for preventing the valve body 20 from coming out of the space 33.
  • a compression coil spring 17 for urging the pipe 12 forward is provided between the front faces of the libs 16B and the inner side of the bell-shaped valve portion 15 in a state wherein the rear half portion of the pipe 12 is inserted into the coil spring 17.
  • the above operational bar 22 is slender enough not to prevent the material 24 from passing through the conduit 32 of the pipe 12 and is slightly shorter than the distance between the two valve bodies 19 and 20 in a state where the valve body 19 closes the conduit 32 and the valve body 20 closes the suction hole 18 as shown in FIG. 3.
  • the container 6 is provided, at its bottom, with a piston-like movable bottom body 23 which is slidable axially in close contact with the inner peripheral surface of the container 6.
  • the movable bottom body 23 is made of soft synthetic resin or others and has slide edges 23B and 23C which are expanded in a bell-shape respectively at the forward end and the rear end of a cylindrical portion 23A. The tight contact of the slide edges 23B and 23C with the inside peripheral wall of the container 6 ensures the airtightness so that the emulsified material or liquid material 24 filled in the container 6 may not leak therefrom.
  • a reference numeral 25 indicates a bottom plate for preventing the movable bottom body 23 from dropping off from the rear end of the container 6.
  • the bottom plate 25 is inserted into the peripheral surface of the opened rear end of the container 6.
  • the bottom plate 25 functions as a reinforcement member for preventing the deformation of the container by outside forces in order to keep the close contact of the slide edges 23B and 23C with the inside of the container 6.
  • the bottom plate 25 has, at its center, a projected bar 25A which is projected into the cylindrical portion 23D of the bottom body 23 to restrict the rearward movement of the bottom body 23.
  • the bottom plate 25 is provided with a plurality of air passages 25B for preventing air pressure in a rear space 34 defined by the bottom body 23 and the bottom plate 25 from becoming negative when the bottom plate 25 is moved forward during the use of the brush 1.
  • the handle 2 is held in one hand in the state shown in Fig. 3.
  • the bristle-planted rod 3 is pushed rearward or toward the container 6 by putting a thumb on the operational projection 11, by pushing the tip of the rod 3 with the other hand, or by pressing the tip of the rod 3 against something.
  • the rear portion of the rod 3 is pushed into the handle 2 along the bearing portion 9 as shown in Fig. 4 with the operational pipe 12 being pushed to advance in the handle main body 5.
  • valve portion 15 When the valve portion 15 is slid forward, the front lip portion 15A is forced to expand radially thereby obtaining a close contact with the inner peripheral wall of the body 5. Further, the forward valve body 19 closes the conduit 32. Accordingly, air or dirty water does not enter or permeate into the inside of the suction chamber 21 in a negative pressure condition through gaps of sliding portions of the bearing portion 9. The suction results in a negative pressure in the container 6 to cause the movable bottom body 23 to advance for a short distance in close contact with the inside peripheral wall of the container 6.
  • the rod 3 is again pushed rearward as described above. This time the forward valve body 19 opens the conduit 32 of the pipe 12 and the rear valve body 20 closes the suction hole 18 of the valve seat member 16. The material sucked in the suction chamber 21 is fed into the hole 31 and the material passage 8 of the rod 3 (Fig. 6). Thereafter, the rod 3 is freed from the push, and the material 24 in the suction chamber 21 stops flowing forward and the material 24 in the container 6 is sucked from the container 6 into the suction chamber 21 of the body 5 (Fig. 7). Similarly as described above this suction causes the movable bottom body 23 in the container 6 to move forward in response to the sucked amount of the material 24.
  • the brush 1 When the brush 1 is initially used, this operation is repeated two or three times to fill the body 5, the conduit 32 and the material passage 8 with the material 24. After this, one push of the rod 3 feeds an amount of the material 24 suitable for one operation onto the bristle-planted surface 3A. Thus, the brush 1 is ready for use. Individually if the amount of the material 24 fed onto the surface 3A is not enough, twice- or more than twice-pushes will be given.
  • the container 6 When the material 24 in the container 6 has run out, the container 6 is unscrewed from the rear end of the body 5, a cap (not shown) screwed on a fresh container 6 at the male thread 6A thereof is disengaged, and the male thread 6A of the fresh container is engaged with the female thread 5A of the body 5. Then immediately the brush 1 can be again used continuously.
  • the opening of the material passage 8 opening on the bristle-planting surface 3A of the rod 3 may become dry during a continuous use, the whole bristles 7 may be covered with a cap 26 as shown by a phantom line in Fig. 1.
  • the operational bar 22 is provided between the forward and rear valve bodies 19 and 21 to control the open-close movements of the two valve bodies 19 and 20.
  • the bar 22 can ensure a reliable alternative movement of the two valve bodies as shown in FIGS. 4 to 7. Further, if the length of the bar 22 is properly adjusted, the 'necessary supply of the material 24 to the surface 3A can be ensured.
  • the forward valve body 19 is an elastic valve member which can shrink and expand by itself, a special coil spring for urging a valve body toward the front opening of the pipe 12 is not necessary thereby to make the construction of a valve mechanism simple.
  • the brush 1 of this invention comprises the bristle-planted rod 3 having the operational projection 11, and by the rod being pushed toward the main body 5, it can feed a cartain amount of the material 24 onto the bristle-planted surface 3A.
  • this makes it possible to use the brush with one touch of operation.
  • one push of the rod 3 feeds a predetermined amount of the material, its users do not need to pay attention to how much the material should be squeezed for one operation as they do with the conventional operation and wasteful use of excessive material can be avoided.
  • the material 24 is fed by simply pushing the rod 3. Accordingly, when the brush is used as a toothbrush, even infants and children can use the brush 1 easily. Additionally the material container 6 is easily detached from the main body 5 and disposable, and economically the main body 5 of the brush can be used for a long time.
  • the movable bottom body 23 moves forward in response to a decrease of the material 24 in the container 6 when the rod 3 is pushed rearward to feed the material 24 toward the rod 3. This perfectly prevents air from being sucked from the outside into the material 24 in the container 6. It is desirable in terms of hygiene that the material can be fed in a perfectly sealed condition.
  • the brush 1 of this invention comprises a small number of components and can be easily fabricated.
  • a great number of fine or thick bristles for applying the material 24 on the head of the rod 3 are planted a great number of fine or thick bristles for applying the material 24.
  • a piece of sponge, a piece of rubber or a member having a convex-concave surface for applying the material 24 thereon may be attached to the head of the rod 3.
