Description

  The present invention relates to a coating brush.

  Conventionally, for example, some hair dyes or the like use a mixture of a plurality of types of drugs having different properties immediately before use.

  And as an application brush for applying such a mixture, for example, as shown in Patent Document 1 below, on the upper surface of a brush head in which a large number of comb teeth are erected, out of both sides in the brushing direction, There is a configuration in which the first agent and the second agent can be mixed while brushing by supplying the first agent on one side and supplying the second agent on the other side and then brushing.

JP-A-9-266814

  However, in the conventional application brush described above, when brushing, a plurality of types of drugs are not mixed well, or when the drugs are supplied to the brush head, the mouth portion of the container in which the drugs are stored is comb teeth. There is a risk that the medicine will be caught on the brush head or the medicine may spill from the brush head.

  Therefore, the present invention has been made in view of the above-described circumstances, and an object thereof is to provide a coating brush capable of improving the operability by reliably mixing a plurality of types of drugs. It is.

In order to solve the above problems, the present invention proposes the following means.
An application brush according to the present invention is an application brush having a brush head in which a large number of comb teeth are erected, and the brush head includes an upper divided body and a lower divided body configured to be separable. The lower divided body is formed with a plurality of supply recesses for supplying a medicine, and the upper divided body is configured to be accommodated in the plurality of supply recesses, and is supplied into the supply recesses. A plurality of extrusion protrusions that extrude the medicine toward the upper end opening edge of the supply recess, and the medicine extruded by the extrusion protrusions is interposed between the plurality of extrusion protrusions in the upper divided body. The supply port is formed to lead to the upper surface of the upper divided body from which the plurality of comb teeth protrude upward.

Due to such characteristics, the medicines pushed out from the plurality of supply recesses by the extrusion protrusions merge while passing through the supply port, and then reach the upper surface of the upper divided body. Therefore, it becomes easy to mix a chemical | medical agent at the time of brushing, and it can mix easily and reliably just before apply | coating multiple types of chemical | medical agent.
In addition, since the portion where the medicine is discharged from the container is a supply recess and not between the conventional comb teeth, when the medicine is discharged, for example, the mouth of the container is caught on the comb teeth, or the medicine from the brush head Can be prevented from falling down and the operability can be improved.

  Further, in the coating brush according to the present invention, of the side surfaces of the extrusion convex portion, the inner side surface facing the supply port side is an inclined surface in which the height of the extrusion convex portion gradually increases as the distance from the supply port side increases. On the other hand, of the inner surface of the supply recess, the surface facing or abutting the inner surface is preferably an inclined surface in which the depth of the supply recess gradually increases as the distance from the supply port side increases. .

  In this case, the chemical | medical agent in each supply recessed part passes through between the inclined surfaces of an extrusion convex part and a supply recessed part, and is extruded toward a supply port. Therefore, since it becomes easy to guide a chemical | medical agent smoothly toward a supply port, operativity can be improved more.

  In the application brush according to the present invention, it is preferable that the comb teeth are formed on both the lower divided body and the upper divided body.

  In this case, since the comb teeth are formed in both the upper divided body and the lower divided body, compared to the case where a large number of comb teeth are formed in one of the upper divided body and the lower divided body. Thus, the arrangement density of the comb teeth in each divided body can be lowered. Therefore, when the upper divided body and the lower divided body are separated and cleaned separately, the space between the comb teeth can be easily cleaned, so that the coating brush can be cleaned effectively.

  In the coating brush according to the present invention, it is preferable that the supply port extends in a meandering manner so as to sew between the comb teeth.

In this case, the shape of the supply port is meandered so as to sew between the comb teeth, so that the respective drugs supplied to the supply recess are mixed to some extent when they merge through the supply port. Thereby, it can apply | coat quickly and uniformly at the time of brushing.
Furthermore, the medicine that has passed through the supply port reaches between the comb teeth without brushing, and the medicine is more easily mixed during brushing.

  According to the application brush according to the present invention, it is possible to reliably mix a plurality of types of medicines and apply them quickly and uniformly, and to improve operability.

Is configured. In addition, the arrangement | positioning area | region in the longitudinal direction of the 2nd comb-tooth group 68 is longer than the arrangement | sequence area | region of the 1st comb-tooth group 37 mentioned above.

  On the other hand, as shown in FIGS. 1 to 5, the upper gripping portion 52 is a plate-like member extending along the longitudinal direction from the central portion in the short side direction on the other longitudinal end surface of the upper head portion 51. When the brush 10 for use is used, it is held together with the lower holding portion 33 described above. Further, a knob piece 69 protruding along the longitudinal direction is formed on the other end surface in the longitudinal direction of the upper grip portion 52. The knob piece 69 is formed such that the width in the short direction is shorter than that of the upper grip portion 52 and the other end surface in the longitudinal direction protrudes from the other end surface in the longitudinal direction of the lower grip portion 33. The lower divided body 22 is configured to be housed in the housing recess 43.

Next, a method for using the above-described application brush 10 will be described.
First, as shown in FIG. 3, the upper gripping portion 52 is gripped, the upper divided body 21 is rotated around the rotation shaft 35 toward the open position, and the supply recess 38 of the lower divided body 22 is opened. And as shown in FIG. 7, the chemical | medical agent (1st agent Y1 and 2nd agent Y2) which each differs in each open | released supply recessed part 38 is supplied.

After the supply of the medicines Y1 and Y2 is completed, the upper divided body 21 is rotated around the rotation shaft 35 toward the closed position. Then, as shown in FIG. 8, the extruding convex portion 54 of the upper head portion 51 enters the supply concave portion 38 of the lower head portion 32, so that the medicines Y <b> 1 and Y <b> 2 in the supply concave portion 38 are supplied to the supply concave portion 38 and the extruded portion. It is pushed upward (toward the upper end opening edge of the supply recess 38) through the space between the side surfaces 38a, 54a of the projection 54 (arrow G in FIG. 8). At this time, the side surfaces 38a and 54a of the supply concave portion 38 and the extrusion convex portion 54 are formed on the inclined surface, so that the medicines Y1 and Y2 pushed out from the supply concave portion 38 are supplied to the side surfaces 38a and 38a of the supply concave portion 38 and the extrusion convex portion 54. It will be smoothly guided to the supply port 53 through 54a. Thereby, operability can be improved.
In particular, since the other side surfaces 38b to 38d and 54b to 54d extend (slidably contact) in the vertical direction, the medicines Y1 and Y2 can surely flow to the supply port 53 side. Furthermore, in this embodiment, since the supply recessed part 38 and the extrusion convex part 54 are formed in the same shape, it can prevent reliably that the chemical | medical agent Y1, Y2 overflows from areas other than between the side surfaces 38a and 54a.

  Then, the medicines Y1 and Y2 pushed upward are merged at the center portion (the periphery of the first comb teeth group 37) on the upper surface of the lower head portion 32, and then the upper side through the supply port 53 of the upper head portion 51. Guided to the upper surface of the head portion 51. As a result, the first agent Y1 and the second agent Y2 reach the periphery of the first comb tooth group 37 on the upper surface of the upper head portion 51.

  In this state, when the gripping part 13 (the lower gripping part 33 and the upper gripping part 52) is gripped and the application brush 10 is moved along the short direction of the brush head 12, the first agent Y1 and the second agent Y2 is applied while being mixed. Thereby, the two-component mixed type drugs Y1 and Y2 can be applied quickly and uniformly, and a good finish can be obtained.

  Further, when the application brush 10 is cleaned after the application brush 10 is used, the upper split body 21 is rotated around the rotation shaft 35 by gripping the knob piece 69 of the upper grip 52 and is opened. The upper divided body 21 and the lower divided body 22 are separated from each other. Thereafter, the upper divided body 21 and the lower divided body 22 separated from each other are washed separately.

As described above, according to the application brush 10 according to the present embodiment, the medicines Y1 and Y2 pushed out from the plurality of supply recesses 38 by the extrusion protrusions 54 merge while passing through the supply port 53, and thereafter It reaches the upper surface of the upper head portion 51. Therefore, the drugs Y1 and Y2 are easily mixed when brushing, and can be easily and reliably mixed immediately before applying the plurality of kinds of drugs Y1 and Y2.
Further, the portion where the medicines Y1 and Y2 are ejected from the container is the supply recess 38, which is not between the comb teeth as in the prior art. Therefore, when the medicines Y1 and Y2 are ejected, for example, the mouth of the container is the comb tooth 11 , 14 and the spilling of the medicines Y1, Y2 from the brush head 12 can be suppressed, and the operability can be improved.

Here, at the time of washing the application brush, if the density of the comb teeth formed on the brush head is high, it is difficult to remove the drugs Y1 and Y2 remaining between the comb teeth.
On the other hand, in the present embodiment, since the comb teeth 11 and 14 are formed on both the upper head portion 51 and the lower head portion 32, a large number of the comb teeth 11 and 32 are collectively arranged on one of the head portions 51 and 32. Compared with the case where the comb teeth 11 and 14 are formed, the arrangement density of the comb teeth 11 and 14 in the head portions 51 and 32 can be reduced. Therefore, when the upper divided body 21 and the lower divided body 22 are separated and cleaned separately, the space between the comb teeth 11 and 14 can be easily cleaned, so that the coating brush 10 can be cleaned effectively.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
For example, the application brush 10 described above is not limited to a hair dye, and any combination type that mixes immediately before applying a plurality of types of drugs can be used.
In the above-described embodiment, the present invention has been described by taking a two-agent mixing type in which two types of drugs Y1 and Y2 are mixed and applied immediately before use as an example, but three or more types of drugs may be mixed. I do not care. Also in this case, it is only necessary to form the supply concave portions 38 and the extrusion convex portions 54 corresponding to the types, and to provide the supply ports 53 for guiding the medicine to the upper surface of the upper head portion 51 between the extrusion convex portions 54. Absent.
Furthermore, in the above-described embodiment, the case where the present invention is applied to the brush head 12 having the grip portion 13 has been described. However, the present invention is not limited to this, and the configuration in which the brush head 12 is directly gripped and operated is not provided. It doesn't matter. In addition, the design of the shape of the brush head 12 and the grip portion 13 can be changed as appropriate.

In the above-described embodiment, the upper divided body 21 and the lower divided body 22 are configured to be relatively rotatable around the rotation shaft 35 by fitting the rotation shaft 35 to the bearing portion 36. However, the present invention is not limited thereto, and the upper divided body 21 and the lower divided body 22 may be integrally connected to each other as a hinge portion (integral molding).
Furthermore, in the closed position of the upper and lower divided bodies 21 and 22, the side surfaces 38a and 54a of the supply concave portion 38 and the extrusion convex portion 54 may be in contact with each other, or a gap may be provided.

  In addition, the present invention is not limited to the above-described embodiment, and may have the following configuration. Specifically, in the application brush 100 illustrated in FIGS. 9 to 12, a first comb tooth group 137 in which a plurality of comb teeth 111 are arranged along the longitudinal direction is formed at the center in the short direction of the upper head portion 51. In addition, meandering supply ports 153 are formed so as to sew between the comb teeth 111 in the surface direction of the upper head portion 51. In the illustrated example, meandering is performed so that the comb teeth 111 are sewn one by one.

According to this configuration, the medicine Y1 supplied to the supply recess 38 is formed by meandering and extending the shape of the supply port 153 so as to sew between the comb teeth 111, as shown in FIGS. , Y2 are mixed to some extent when they merge through the supply port 153. Thereby, it can apply | coat quickly and uniformly at the time of brushing.
Further, the drugs Y1 and Y2 that have passed through the supply port 153 reach between the comb teeth 111 without brushing, and the drugs Y1 and Y2 are more easily mixed during brushing.

In the above-described embodiment, the case where the first comb teeth group 137 is formed in the upper head portion 51 and the meandering supply port 153 is formed has been described. However, the first comb teeth group is formed in the upper head portion 51. A serpentine supply port may be formed in the upper head portion 51 after the first comb teeth group is formed in the lower head portion 32 by, for example, forming a through-hole for inserting the first comb teeth.
In the above-described embodiment, the case where the supply port 153 is formed so as to sew between the comb teeth 111 has been described. However, the present invention is not limited to this, and the supply port 153 is formed so as to sew every plurality of comb teeth 111. It doesn't matter.
Furthermore, the supply port is not limited to a meandering shape or a rectangular shape, and the design can be changed as appropriate.
