Shampoo brush

Abstract

This shampoo brush provides a way to remove dirt from the scalp in a nearly uniform manner while applying a nearly uniform pressure to stimulate the user's head. [Solution] The first inner hollow body 4, located inward of the outermost lateral hollow body 2, is connected and supported to the outermost lateral hollow body only by the first connecting support rib 10. The second inner hollow body 6, located on the inner side of the first inner hollow body 4, is connected and supported to the first inner hollow body 4 only by the second connecting support rib 11, located on the opposite side in the circumferential direction from the first connecting support rib 10. As a result, the outermost brush pins 3 of the adjacent outermost lateral hollow body 2, the first inner brush pins 5 of the first inner hollow body 4, and the second inner brush pins 7 of the second inner hollow body 6 stimulate the user's head with a substantially uniform pressure, thereby removing dirt from the scalp substantially uniformly. Conventional hairbrushes have a problem in that the spiral part of the brush base is formed in a spiral shape, which stimulates the user's head with an uneven pressure, making it impossible to remove dirt from the scalp substantially uniformly.

Description

Technical Field

[0001] The present invention relates to a shampoo brush for washing hair while stimulating the head.

Background Art

[0002] Conventionally, a hair brush that can comb hair while stimulating the head is known. As this type of hair brush, it includes a handle portion 131, a brush base portion 132 is installed at the front end of the handle portion 131, a plurality of brush pins 133 are installed on the brush base portion 132, and at least one spiral groove 321 penetrates through the brush base portion 132, thereby forming a plurality of spiral portions 322 that move up and down (see FIG. 7). And due to the design of this spiral groove 321, when combing hair, the shape of the curve changes according to various head shapes, undulates up and down, and is automatically flexibly adjusted left and right, so that each brush pin 133 approaches the hair root, and while firmly combing the hair, the effect of massage can also be achieved (for example, Patent Document 1). <000,010>

Summary of the Invention

Problems to be Solved by the Invention

[0005] This invention was made in view of the above-mentioned problems, and aims to provide a shampoo brush that can remove dirt from the scalp in a substantially uniform manner while stimulating the user's head with substantially uniform pressure. [Means for solving the problem]

[0006] To solve the above problems and achieve the above objective, the first aspect of the present invention relates to a shampoo brush for washing hair while stimulating the head, comprising: a lateral outermost hollow body formed from a substantially hollow shape; a plurality of outermost brush pins provided on the lower side of the lateral outermost hollow body and formed from a shape extending in the longitudinal direction; a first inner hollow body provided on the inner side of the lateral outermost hollow body and formed from a substantially hollow shape, connected and supported to the lateral outermost hollow body only by a first connecting support rib; a plurality of first inner brush pins provided on the lower side of the first inner hollow body and formed from a shape extending in the longitudinal direction; and a first inner The device comprises a second inner hollow body provided on the inner side of the hollow body, formed from a substantially hollow shape, and connected and supported only by a second connecting support rib provided on the circumferentially opposite side to the first connecting support rib of the first inner hollow body; and a plurality of second inner brush pins provided on the lower surface side of the second inner hollow body, formed from a longitudinally extended shape. Each adjacent outermost lateral hollow body, the first inner hollow body, and the second inner hollow body moves downward with the first or second connecting support rib as a pivot point, thereby allowing for the removal of dirt from the scalp in a substantially uniform manner while stimulating the user's head with a substantially uniform pressure.

[0007] According to this invention, the first inner hollow body, located inward of the outermost lateral hollow body, is connected and supported to the outermost lateral hollow body only by a first connecting support rib, and the second inner hollow body, located on the inner side of the first inner hollow body, is connected and supported to the first inner hollow body only by a second connecting support rib located on the opposite side in the circumferential direction from the first connecting support rib. Therefore, when the second inner hollow body is pressed from above by the user, the second inner hollow body moves downward using the second connecting support rib as a pivot point, and the first inner hollow body also moves downward using the first connecting support rib located on the opposite side in the circumferential direction from the second connecting support rib as a pivot point, thereby allowing the first and second inner hollow bodies to move symmetrically. As a result, the outermost brush pins provided on the adjacent outermost lateral hollow bodies, the first inner brush pins on the first inner hollow body, and the second inner brush pins on the second inner hollow body stimulate the user's head with a substantially uniform pressure, thereby removing dirt from the scalp substantially uniformly.

[0008] A second aspect of this invention relates to a shampoo brush according to the first aspect, comprising: a third inner hollow body provided on the inner side of the second inner hollow body, formed from a substantially hollow shape, and connected and supported only by a third connecting support rib provided on the circumferentially opposite side to the second connecting support rib of the second inner hollow body; and a plurality of third inner brush pins provided on the lower surface side of the third inner hollow body, formed from a longitudinally extending shape. Each adjacent outermost lateral hollow body, the first inner hollow body, the second inner hollow body, and the third inner hollow body move downward with the first connecting support rib, the second connecting support rib, or the third connecting support rib as a pivot point, thereby allowing for the removal of dirt from the scalp substantially uniformly while stimulating the user's head with substantially uniform pressure.

[0009] According to this invention, the first inner hollow body, located in the direction of the outermost lateral hollow body, is connected and supported to the outermost lateral hollow body only by a first connecting support rib; the second inner hollow body, located on the inner side of the first inner hollow body, is connected and supported to the first inner hollow body only by a second connecting support rib located on the circumferential side of the first connecting support rib; and the third inner hollow body, located on the inner side of the second inner hollow body, is connected and supported to the second inner hollow body only by a third connecting support rib located on the circumferential side of the second connecting support rib. As a result, the third inner hollow body is moved downward with the third connecting support rib as a pivot point, the second inner hollow body is moved downward with the second connecting support rib located on the circumferential side of the third connecting support rib as a pivot point, and the first inner hollow body is moved downward with the first connecting support rib located on the circumferential side of the second connecting support rib as a pivot point, thereby allowing the first inner hollow body, the second inner hollow body, and the third inner hollow body to move symmetrically. As a result, the outermost brush pins located in the adjacent outermost lateral hollow bodies, the first inner brush pins in the first inner hollow body, the second inner brush pins in the second inner hollow body, and the third inner brush pins in the third inner hollow body stimulate the user's head with a nearly uniform pressure, thereby removing dirt from the scalp nearly uniformly.

[0010] A third aspect of this invention relates to the shampoo brush according to the second aspect, wherein the first connecting support rib, the second connecting support rib, and the third connecting support rib are provided on the longitudinal front side or rear side where the user rests their hand.

[0011] According to this invention, the first, second, and third connecting support ribs are provided on the forward or backward side in the longitudinal direction where the user places their hand, respectively. This allows the adjacent outermost lateral hollow body, the first inner hollow body, the second inner hollow body, and the third inner hollow body to be easily moved symmetrically to the forward and backward sides. As a result, the pressure applied by the outermost brush pins on the adjacent outermost lateral hollow bodies, the first inner brush pins on the first inner hollow body, the second inner brush pins on the second inner hollow body, and the third inner brush pins on the third inner hollow body to the user's head can be easily changed, while the user is stimulated with a substantially uniform pressure throughout, allowing for substantially uniform removal of dirt from the scalp.

[0012] A fourth aspect of this invention relates to a shampoo brush according to the third aspect, wherein the first connecting support rib, the second connecting support rib, and the third connecting support rib are each formed from one to three pieces, and are configured to be connected to the adjacent outermost lateral hollow body, the first inner hollow body, the second inner hollow body, and the third inner hollow body, respectively.

[0013] A fifth aspect of this invention is a shampoo brush according to the fourth aspect, wherein the outermost lateral hollow body, the first inner hollow body, the second inner hollow body, and the third inner hollow body are each formed in a symmetrical shape with respect to the midpoint in the longitudinal direction.

[0014] According to this invention, the outermost lateral hollow body, the first inner hollow body, the second inner hollow body, and the third inner hollow body are each formed in a symmetrical shape with the midpoint in the longitudinal direction as the boundary. Therefore, the shampoo brush can be used without discomfort regardless of whether it is held in the forward or reverse direction, and the user can use the shampoo brush without being conscious of the direction in which they are gripping it.

[0015] A sixth aspect of this invention is a shampoo brush according to the fifth aspect, characterized in that the outermost lateral hollow body is formed such that the left and right ends in the longitudinal direction are higher than the left and right central portion between the left and right ends.

[0016] According to the present invention, since the left and right longitudinal ends of the lateral outermost hollow body are formed higher than the left and right central portions between the left and right ends, it is easier to hold the shampoo brush and it is possible to prevent accidental dropping.

Effects of the Invention

[0017] According to the shampoo brush of the present invention, it is possible to remove dirt on the scalp substantially uniformly while applying stimulation to the user's head with a substantially uniform pressing force.

Modes for Carrying Out the Invention

[0019] (First Embodiment) Hereinafter, the first embodiment of the shampoo brush of the present invention will be described with reference to the drawings. Here, FIG. 1 is an upper perspective view of the shampoo brush in the first embodiment of the present invention, FIG. 2 is a lower perspective view of the shampoo brush, and FIG. 3 is a cross-sectional view of the shampoo brush.

[0020] The shampoo brush 1 is for washing hair while stimulating the head, and has a lateral outermost hollow body 2, an outermost brush pin 3, a first inner hollow body 4, a first inner brush pin 5, a second inner hollow body 6, a second inner brush pin 7, a third inner hollow body 8, and a third inner brush pin 9.

[0021] The lateral outermost hollow body 2 is formed in a substantially hollow shape. Specifically, the lateral outermost hollow body 2 is formed in a substantially elliptical shape with a substantially hollow planar shape and having substantially the same lateral width (the same applies to other hollow bodies such as the "first inner hollow body 4, second inner hollow body 6, third inner hollow body 8" below). Thus, since the lateral outermost hollow body 2 is formed in a substantially elliptical shape that is symmetric with respect to the middle part in the longitudinal direction, the shampoo brush 1 can be used in either the forward or reverse direction, and the user can use it without being conscious of the direction of gripping the shampoo brush 1. In this embodiment, the planar shape is formed in a substantially elliptical shape with a substantially hollow shape, but it is not limited to this, and it may be formed in other substantially hollow shapes such as a substantially square shape with a substantially hollow shape described later (the same applies to other hollow bodies such as the "first inner hollow body 4, second inner hollow body 6, third inner hollow body 8" below). Also, in this embodiment, the lateral outermost hollow body 2 is formed in a symmetric shape with respect to the middle part in the longitudinal direction in a substantially elliptical shape, but it is not limited to this, and the lateral outermost hollow body 2 may be formed in a substantially symmetric shape with respect to the middle part in the longitudinal direction in a substantially elliptical shape (the same applies to other hollow bodies such as the "first inner hollow body 4, second inner hollow body 6, third inner hollow body 8" below).

[0022] A plurality of outermost brush pins 3 are provided on the lower surface side of the lateral outermost hollow body 2 and are formed in a shape extending in the longitudinal direction. Specifically, the outermost brush pins 3 are formed in a thin rod-like shape with substantially the same diameter that becomes slightly thinner towards the tip, and a plurality of them are provided on the lower surface side of the lateral outermost hollow body 2 at substantially equal intervals.

[0023] The first inner hollow body 4 is located on the inner side of the outermost lateral hollow body 2, is formed from a substantially hollow shape, and is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10 (see Figure 1). Specifically, the first inner hollow body 4 is formed from a substantially hollow, substantially elliptical shape that is smaller and similar in shape to the outermost lateral hollow body 2. Thus, the first inner hollow body 4 is formed in a substantially elliptical shape with a symmetrical shape with the midpoint in the longitudinal direction as the boundary. The first inner hollow body 4 and the outermost lateral hollow body 2 are connected by the first connecting support rib 10 located on the circumferential forward side, and the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10. Here, the statement "the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10" means that if the first connecting support rib 10 is a member that does not support the outermost lateral hollow body 2, it is not a problem even if it is connected to the outermost lateral hollow body 2 with a member other than the first connecting support rib 10, and therefore it corresponds to "the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10." Furthermore, the reason why the first inner hollow body 4 described above is roughly hollow is because the first connecting support rib 10 (etc.) is located in the hollow part of the first inner hollow body 4. Also, although it is stated that "the first inner hollow body 4 and the outermost lateral hollow body 2 are connected by the first connecting support rib 10 provided on the circumferential forward side," if the shampoo brush 1 is reversed in terms of forward and backward directions, it becomes "the first inner hollow body 4 and the outermost lateral hollow body 2 are connected by the first connecting support rib 10 provided on the circumferential rear side," which is equivalent. In this embodiment, the first inner hollow body 4 and the outermost lateral hollow body 2 are connected by a single first connecting support rib 10. However, if the first connecting support rib 10 is provided on the opposite side in the circumferential direction from the second connecting support rib 11, the first inner hollow body 4 and the outermost lateral hollow body 2 may be connected by a first connecting support rib 10 consisting of two or three ribs. That is, if the first connecting support rib 10 is provided on the opposite side in the circumferential direction from the second connecting support rib 11, it may be formed from one to three ribs and connect the outermost lateral hollow body 2 and the first inner hollow body 4. Furthermore, the first connecting support rib 10 may be composed of multiple ribs other than one to three.

[0024] Multiple first inner brush pins 5 are provided on the lower surface side of the first inner hollow body 4 and are formed from a shape that extends in the longitudinal direction. The specific details of the first inner brush pins 5 are almost the same as those of the outermost brush pins 3, so a detailed explanation is omitted.

[0025] The second inner hollow body 6 is provided on the inner side of the first inner hollow body 4, is formed from a substantially hollow shape, and is connected and supported to the first inner hollow body 4 only by a second connecting support rib 11, which is provided on the circumferentially opposite side to the first connecting support rib 10. Specifically, the second inner hollow body 6 is formed from a substantially hollow, substantially elliptical shape that is smaller and similar in shape to the first inner hollow body 4. Thus, the second inner hollow body 6 is formed in a substantially elliptical shape with a symmetrical shape with the middle part in the longitudinal direction as the boundary. The second inner hollow body 6 and the first inner hollow body 4 are connected by a second connecting support rib 11 provided on the circumferentially rear side, and the second inner hollow body 6 is connected and supported to the first inner hollow body 4 only by the second connecting support rib 11. Here, "the second inner hollow body 6 is connected and supported to the first inner hollow body 4 only by the second connecting support rib 11" means, similar to the above-mentioned statement "the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10," that the second connecting support rib 11 is a member that does not support the first inner hollow body 4, and it is acceptable for it to be connected to the first inner hollow body 4 with a member other than the second connecting support rib 11, thus corresponding to "the second inner hollow body 6 is connected and supported to the first inner hollow body 4 only by the second connecting support rib 11." Furthermore, the reason why the second inner hollow body 6 is approximately hollow is that, similar to the first inner hollow body 4, the second connecting support rib 11 (etc.) is present in the hollow portion of the first inner hollow body 4. Furthermore, as described above, if we assume that "the first inner hollow body 4 and the outermost lateral hollow body 2 are connected by a first connecting support rib 10 provided on the circumferential rear side," then "the second inner hollow body 6 and the first inner hollow body 4 are connected by a second connecting support rib 11 provided on the circumferential front side." In this way, the first connecting support rib 10 and the second connecting support rib 11 are provided on the front or rear side in the longitudinal direction where the user places their hand. This allows the outermost brush pins 3 provided on the adjacent outermost lateral hollow body 2, the first inner brush pins 5 on the first inner hollow body 4, and the second inner brush pins 7 on the second inner hollow body 6 to press against the user's head, while simultaneously providing the user with a nearly uniform pressure to stimulate the scalp and remove dirt nearly uniformly.In this embodiment, the second inner hollow body 6 and the first inner hollow body 4 are connected by a single second connecting support rib 11. However, if the second connecting support rib 11 is provided on the opposite side in the circumferential direction from the first connecting support rib 10, the second inner hollow body 6 and the first inner hollow body 4 may be connected by a second connecting support rib 11 composed of two or three ribs. In other words, if the second connecting support rib 11 is provided on the opposite side in the circumferential direction from the first connecting support rib 10, the second connecting support rib 11 may be formed from one to three ribs and connect the first inner hollow body 4 and the second inner hollow body 6. Furthermore, the second connecting support rib 11 may be composed of multiple ribs other than one to three.

[0026] Multiple second inner brush pins 7 are provided on the lower surface side of the second inner hollow body 6 and are formed from a shape that extends in the longitudinal direction. The specific details of the second inner brush pins 7 are almost the same as those of the outermost brush pins 3 and the first inner brush pins 5, so a detailed explanation is omitted.

[0027] The third inner hollow body 8 is located on the inner side of the second inner hollow body 6, is formed from a substantially hollow shape, and is connected and supported to the second inner hollow body 6 only by a third connecting support rib 12 located on the circumferentially opposite side to the second connecting support rib 11. Specifically, the third inner hollow body 8 is formed from a substantially hollow, substantially elliptical shape that is smaller and similar in shape to the second inner hollow body 6. Thus, the third inner hollow body 8 is formed in a substantially elliptical shape with a symmetrical shape with the midpoint in the longitudinal direction as the boundary. The third inner hollow body 8 and the second inner hollow body 6 are connected by a third connecting support rib 12 located on the circumferentially forward side, and the third inner hollow body 8 is connected and supported to the second inner hollow body 6 only by the third connecting support rib 12. Here, the statement "the third inner hollow body 8 is connected and supported to the second inner hollow body 6 only by the third connecting support rib 12" means, similar to the statement above that "the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib," that the third connecting support rib 12 is a member that does not support the second inner hollow body 6, and it is acceptable for it to be connected to the second inner hollow body 6 with a member other than the third connecting support rib 12, thus corresponding to the statement "the third inner hollow body 8 is connected and supported to the second inner hollow body 6 only by the third connecting support rib 12." Furthermore, the reason why the third inner hollow body 8 is approximately hollow, as mentioned above, is because, similar to the second inner hollow body 6, the third connecting support rib 12 (etc.) is present in the hollow portion of the second inner hollow body 6. Furthermore, as mentioned above, if we assume that "the second inner hollow body 6 and the first inner hollow body 4 are connected by a second connecting support rib 11 provided on the circumferential forward side," then "the third inner hollow body 8 and the second inner hollow body 6 are connected by a third connecting support rib 12 provided on the circumferential rear side." Thus, the second connecting support rib 11 and the third connecting support rib 12 are provided on the longitudinal forward or rear side where the user places their hand.

[0028] Multiple third inner brush pins 9 are provided on the lower side of the third inner hollow body 8 and are formed from a shape that extends in the longitudinal direction. The specific details of the third inner brush pins 9 are almost the same as those of the outermost brush pins 3, the first inner brush pins 5 and the second inner brush pins 7, so a detailed explanation is omitted. This allows the outermost brush pins 3 on the adjacent outermost lateral hollow body 2, the first inner brush pins 5 on the first inner hollow body 4, the second inner brush pins 7 on the second inner hollow body 6 and the third inner brush pins 9 on the third inner hollow body 8 to easily change the pressure applied to the user's head, while simultaneously providing the user with a nearly uniform pressure to stimulate the scalp and remove dirt nearly uniformly.

[0029] A fourth inner section 13 is provided on the inner side of the third inner hollow body 8. This fourth inner section 13 is provided on the inner side of the third inner hollow body 8 and is connected and supported to the third inner hollow body 8 only by a fourth connecting support rib 14 provided on the circumferentially opposite side to the third connecting support rib 12. Specifically, the outer surface of the fourth inner section 13 is formed from a substantially elliptical shape that is a smaller, similar shape to the second inner hollow body 6. Thus, the third inner hollow body 8 is formed in a substantially elliptical shape with a symmetrical shape with the middle part in the longitudinal direction as the boundary. The fourth inner section 13 and the third inner hollow body 8 are connected by a fourth connecting support rib 14 provided on the circumferentially rear side, and the fourth inner section 13 is connected and supported to the third inner hollow body 8 only by the fourth connecting support rib 14. Here, "the fourth inner body 13 is connected and supported to the third inner hollow body 8 only by the fourth connecting support rib 14" means, similar to "the first inner hollow body 4 is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib" as described above, that the fourth connecting support rib 14 is a member that does not support the third inner hollow body 8, and it does not matter if it is connected to a member other than the fourth connecting support rib 14, and therefore "the fourth inner body 13 is connected and supported to the third inner hollow body 8 only by the fourth connecting support rib 14". Furthermore, as described above, if "the third inner body 8 and the second inner hollow body 6 are connected by the third connecting support rib 12 provided on the circumferential rear side", then "the fourth inner body 14 and the third inner hollow body 8 are connected by the fourth connecting support rib 14 provided on the circumferential front side". Note that in this embodiment, the fourth inner body 13 is not made substantially hollow, but it is not limited to this and may be made substantially hollow. Furthermore, in this embodiment, the fourth inner part 13 is provided on the inner side of the third inner hollow body 8, but this is not limited to this, and the fourth inner part 13 may not be provided. Moreover, a fifth inner hollow body (fifth inner part) may be provided on the inner side of the fourth inner part 13, and a sixth inner hollow body (fifth inner part) may be provided on the inner side of the fifth inner hollow body, or even more than that, a "0th inner hollow body (with brush pin)" may be provided.

[0030] Multiple fourth inner brush pins 15 are provided on the lower surface of the fourth inner section 13. The specific details of these fourth inner brush pins 15 are almost the same as those of the outermost brush pin 3, first inner brush pin 5, second inner brush pin 7, and third inner brush pin 9 described above, so their explanation will be omitted. In this way, the third connecting support rib 12 and the fourth connecting support rib 13 are provided on the longitudinal forward or rear side where the user places their hand. This allows the outermost brush pin 3 provided on the adjacent outermost lateral hollow body 2, the first inner brush pin 5 on the first inner hollow body 4, the second inner brush pin 7 on the second inner hollow body 6, the third inner brush pin 9 on the third inner hollow body 8, and the fourth inner brush pin 15 on the fourth inner section 13 to easily change the pressure applied to the user's head, while simultaneously providing the user with a nearly uniform pressure to stimulate the scalp and remove dirt nearly uniformly.

[0031] Next, we will describe an example of how to use the shampoo brush 1 of this invention.

[0032] The user of the shampoo brush 1 places their index and middle fingers on the top of the shampoo brush 1 and, while holding the shampoo brush 1, brings the first inner brush pins 5 to the fourth inner brush pins 15 of the shampoo brush 1 into contact with their head to comb their hair. At that time, the outermost hollow body 2 on the side is formed so that both the left and right ends in the longitudinal direction are higher than the left and right center section between the left and right ends, making the shampoo brush 1 easier to hold and preventing it from being accidentally dropped. Then, by pressing the area around the fourth inner body 13 (the innermost inner body (hollow body)) with the index or middle finger on the top of the shampoo brush 1, the fourth inner body 13 is moved downward with the fourth connecting support rib 14 as the pivot point, the third inner hollow body 8 is moved downward with the third connecting support rib 12, which is located on the opposite side of the circumference from the fourth connecting support rib 14 as the pivot point, the second inner hollow body 6 is moved downward with the second connecting support rib 11, which is located on the opposite side of the circumference from the third connecting support rib 12 as the pivot point, and the first inner hollow body 4 is moved downward with the first connecting support rib 10, which is located on the opposite side of the circumference from the second connecting support rib 11 as the pivot point, thereby allowing the first inner hollow body 4, the second inner hollow body 6, and the third inner hollow body to move symmetrically. As a result, the outermost brush pins 3 on the adjacent outermost lateral hollow body 2, the first inner brush pin 5 on the first inner hollow body 4, the second inner brush pin 7 on the second inner hollow body 6, and the third inner brush pin 9 on the third inner hollow body 8 can stimulate the user's head with a nearly uniform pressure, thereby removing dirt from the scalp nearly uniformly. This effect can be achieved even when the fourth inner part 13 is not provided, as described above.

[0033] (Second Embodiment) Next, a second embodiment of the shampoo brush of the present invention will be described with reference to Figures 4 to 6. Here, Figure 4 is an upper perspective view of the shampoo brush in the second embodiment of the present invention, in which the hollow body is formed in a substantially hollow, substantially rectangular shape; Figure 5 is a lower perspective view of the same shampoo brush; and Figure 6 is a cross-sectional view of the same shampoo brush. In the second embodiment, identical components that differ in shape from those in the first embodiment will be denoted by the same reference numerals.

[0034] The difference between the second embodiment and the first embodiment is that in the first embodiment, the outermost lateral hollow body 2, first inner hollow body 4, second inner hollow body 6, third inner hollow body 8, and fourth inner part 13 have a planar shape that is (approximately hollow) and approximately elliptical, whereas in the second embodiment, the outermost lateral hollow body 2, first inner hollow body 4, second inner hollow body 6, and third inner hollow body 8 have a planar shape that is (approximately hollow) and approximately rectangular. Other aspects are the same as in the first embodiment, so further explanation is omitted.

[0035] In this way, when the hollow bodies (the outermost lateral hollow body 2, the first inner hollow body 4, the second inner hollow body 6, and the third inner hollow body 8) are made into roughly square shapes with roughly hollow bodies, it becomes easier to place fingers on the top surface of the shampoo brush 1, allowing for a more stable placement of the fingers.

[0036] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. Furthermore, the scope of the present invention is indicated not by the foregoing description but by the claims for utility model registration, and all modifications within the meaning and scope equivalent to the claims for utility model registration are intended to be included.

[0037] Modified examples of this embodiment will be described below. (Variation 1) The difference between Modified Example 1 and this embodiment is that in this embodiment, a third connecting support rib 12, a third inner hollow body 8, and a third inner brush pin 9 (and a fourth connecting support rib 14, a fourth inner brush pin 15, and a fourth inner part 13) are provided, whereas Modified Example 1 does not provide a third connecting support rib 12, a third inner hollow body 8, a third inner brush pin 9, a fourth connecting support rib 14, a fourth inner brush pin 15, and a fourth inner part 13. Thus, if the third connecting support rib 12, the third inner hollow body 8, the third inner brush pin 9, the fourth connecting support rib 14, the fourth inner brush pin 15, and the fourth inner part 13 are not provided, then the outermost lateral hollow body 2 is formed from a substantially hollow shape, multiple outermost brush pins 3 are provided on the lower surface side of the outermost lateral hollow body 2 and are formed from a shape extending in the longitudinal direction, and the first is provided on the inner side of the outermost lateral hollow body 2 and is formed from a substantially hollow shape and is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10. The device comprises an inner hollow body 4, a plurality of first inner brush pins 5 provided on the lower surface side of the first inner hollow body 4 and formed from a shape extending in the longitudinal direction, a second inner hollow body 6 provided on the inner side of the first inner hollow body 4 and formed from a substantially hollow shape, connected and supported to the first inner hollow body 4 only by a second connecting support rib 11 provided on the circumferentially opposite side to the first connecting support rib 10, and a plurality of second inner brush pins 7 provided on the lower surface side of the second inner hollow body 6 and formed from a shape extending in the longitudinal direction. Thus, in Modification 1, the third connecting support rib 12, the third inner hollow body 8, the fourth connecting support rib 14, and the fourth inner part 13 are omitted, and the structure consists of the outermost lateral hollow body 2, the outermost brush pin 3, the first connecting support rib 10, the first inner hollow body 4, the first inner brush pin 5, the second connecting support rib 11, the second inner hollow body 6, and the second inner brush pin 7. In addition, other components may be added as long as the structure has the outermost lateral hollow body 2, the outermost brush pin 3, the first connecting support rib 10, the first inner hollow body 4, the first inner brush pin 5, the second connecting support rib 11, the second inner hollow body 6, and the second inner brush pin 7.In other words, in this embodiment, the outermost lateral hollow body 2, the first inner hollow body 4, the second inner hollow body 6, and the third inner hollow body 8 (and the fourth inner hollow body 13) are provided. In Modification 1, the outermost lateral hollow body 2, the first inner hollow body 4, and the second inner hollow body 6 are provided, but the embodiment is not limited to this. It may also consist of two bodies, the outermost lateral hollow body 2 (including the outermost brush pin 3) and the first inner hollow body 4 (including the first inner brush pin 5), or, as described above, three bodies, the outermost lateral hollow body 2 (including the outermost brush pin 3), the first inner hollow body 4 (including the first inner brush pin 5), and the second inner hollow body 6 (including the second inner brush pin 7). It may also consist of four bodies: the outermost lateral hollow body 2 (including the outermost brush pin 3), the first inner hollow body 4 (including the first inner brush pin 5), the second inner hollow body 6 (including the second inner brush pin 7), and the third inner hollow body 8 (including the third inner brush pin 9). Furthermore, it may consist of multiple bodies such as the outermost lateral hollow body 2 (including the outermost brush pin 3), the first inner hollow body 4 (including the first inner brush pin 5), the second inner hollow body 6 (including the second inner brush pin 7), the third inner hollow body 8 (including the third inner brush pin 9) (fourth inner part 13 (fourth inner brush pin 15)).

[0038] As a result, in Modification 1, the adjacent outermost lateral hollow body 2, the first inner hollow body 4, and the second inner hollow body 6 move downward using the first connecting support rib 10 and the second connecting support rib 11 as pivot points, thereby allowing for a nearly uniform application of pressure to the user's head while removing dirt from the scalp in a nearly uniform manner. In other words, the first inner hollow body 4, which is located inward of the outermost lateral hollow body 2, is connected and supported to the outermost lateral hollow body 2 only by the first connecting support rib 10, and the second inner hollow body 6, which is located on the inward side of the first inner hollow body 4, is connected and supported to the first inner hollow body 4 only by the second connecting support rib 11, which is located on the opposite side in the circumferential direction from the first connecting support rib 10. Therefore, when the second inner hollow body 6 is pressed from above by the user, the second inner hollow body 6 moves downward with the second connecting support rib 11 as a fulcrum, and the first inner hollow body 4 also moves downward with the first connecting support rib 10, which is located on the opposite side in the circumferential direction from the second connecting support rib 11, as a fulcrum, thereby allowing the first inner hollow body 4 and the second inner hollow body 6 to move symmetrically. As a result, the outermost brush pins 3 provided on the adjacent outermost lateral hollow body 2, the first inner brush pins 5 on the first inner hollow body 4, and the second inner brush pins 7 provided on the second inner hollow body 6 stimulate the user's head with a nearly uniform pressure, thereby removing dirt from the scalp nearly uniformly.
