[0015] Hereinafter, an embodiment of the present invention will be described.

[0016] (First embodiment) First, a brush 100 according to a first embodiment of the present invention will be described with reference to FIGS.

[0017] The brush 100 is used, for example, for massaging the scalp, etc., and is used after lathering shampoo. As shown in Figs. 1 and 2, the brush 100 includes a base 1 and a plurality of protrusions 2, which are integrally formed. The brush 100 is made of synthetic rubber, such as silicone rubber, and is configured to be elastically deformable. The front of the brush 100 is in the X1 direction, and the rear of the brush 100 is in the X2 direction.

[0018] The brush 100 has multiple protrusions 2 arranged on the front side 1f (see FIG. 1) of the base 1, and is configured so that the user can hold it from the rear side 1r (see FIG. 2) of the base 1. The user holding the brush 100 can press the multiple protrusions 2 against the scalp, thereby massaging the scalp. The front side 1f is an example of the "one side" of the present invention, and the rear side 1r is an example of the "other side" of the present invention.

[0019] The base 1 is a circular ring having a hole 1h at the center. Specifically, the base 1 is provided such that a plurality of spherical portions 11 are connected in a circular ring shape. That is, the plurality of spherical portions 11 are arranged so as to be continuous in the circumferential direction of the base 1. Each spherical portion 11 is formed in a spherical shape, and adjacent spherical portions 11 are connected to both ends of the base 1 in the circumferential direction.

[0020] The base 1 has recesses 12 between adjacent spherical portions 11. That is, each recess 12 is constituted by a constriction formed by adjacent spherical portions 11. That is, each recess 12 is constituted by approximately half of the curved surface of one of the adjacent spherical portions 11 on the side closer to the other spherical portion 11, and approximately half of the curved surface of the other of the adjacent spherical portions 11 on the side closer to the one spherical portion 11.

[0021] Specifically, as shown in Figs. 3 to 5, each recess 12 is provided over the entire circumference between adjacent spherical portions 11. Each recess 12 is provided in a groove shape extending between the outer edge side 1o, the rear side 1r, the inner edge side 1i, and the front side 1f of the base 1. As a result, each recess 12 is formed in an annular groove shape. Therefore, a plurality of recesses 12 are arranged at intervals in the circumferential direction on the outer edge side 1o of the base 1. The boundary portion (the deepest portion of the recess 12) between adjacent spherical portions 11 has a cross section (a cross section when cut by a plane passing through the center of each of the adjacent spherical portions 11) perpendicular to the extending direction of the recess 12, which is formed in an arc shape. In other words, the connection points of the curved surfaces of adjacent spherical portions 11 are rounded.

[0022] The protrusions 2 are configured to protrude forward (in the X1 direction) from the base 1. The protrusions 2 are formed in a conical shape, and a plurality of protrusions 2 are provided on each spherical portion 11. The protrusions 2 are set to have the same height. For example, the central axis of the protrusions 2 is arranged parallel to the central axis of the base 1.

[0023] In the first embodiment, as shown in Fig. 3, eight spherical portions 11 are provided. Therefore, eight recesses 12 are provided, and the eight recesses 12 are arranged at 45 degree intervals in the circumferential direction. Also, three protrusions 2 are provided on each spherical portion 11. Therefore, the brush 100 is provided with 24 protrusions 2.

[0024] The outer diameter of the annular base 1 is preferably 70 mm to 100 mm, more preferably 80 mm to 90 mm. The diameter of the spherical portion 11 is preferably 20 mm to 35 mm, more preferably 25 mm to 30 mm. The height of the protrusion 2 is preferably 10 mm to 20 mm, more preferably 13 mm to 17 mm. The base diameter of the protrusion 2 is preferably 5 mm to 15 mm, more preferably 8 mm to 12 mm.

[0025] -effect- In the first embodiment, as described above, multiple spherical portions 11 are arranged so as to be connected in a circular ring shape, and recesses 12 are formed between adjacent spherical portions 11. This allows the user to hook their fingers into the recesses 12 when gripping the brush 100, thereby improving ease of holding when in use.

[0026] In the first embodiment, the base 1 has holes 1h, which allows shampoo foam to circulate through the holes 1h. The brush 100 is easily elastically deformed to fit the palm of the user's hand when in use, making it easier to fit the scalp and preventing the protrusions 2 from escaping to the outside and making it easier to properly contact the scalp. Furthermore, when the brush 100 is not in use, the brush 100 can be hung on a hook (not shown) for easy hygienic storage.

[0027] Furthermore, in the first embodiment, the cross section of the boundary between adjacent spherical portions 11 is formed in an arc shape, which makes it easier for the user's fingers to fit into the recesses 12 than when the cross section of the boundary between adjacent spherical portions is formed in a V shape, making the brush 100 easier to hold.

[0028] Second embodiment Next, a brush 100a according to a second embodiment of the present invention will be described with reference to FIGS.

[0029] 6 and 7, the brush 100a includes a base 1a and a plurality of protrusions 2, which are integrally formed with the base 1a and the plurality of protrusions 2. The brush 100a is made of synthetic rubber such as silicone rubber, and is configured to be elastically deformable.

[0030] The base 1a is a circular ring having a hole 1h at the center. Specifically, the base 1a is provided such that a plurality of spherical portions 11a are connected in a circular ring shape. That is, the plurality of spherical portions 11a are arranged so as to be continuous in the circumferential direction of the base 1a. Each spherical portion 11a is formed in a semi-spherical shape cut by a plane passing through the center of the sphere, and adjacent spherical portions 11a are connected to both ends in the circumferential direction of the base 1a. Each spherical portion 11a is arranged so that a flat surface portion 111a (see FIG. 6) faces the front side (X1 direction side). Therefore, the front side 1f of the base 1 is formed by the plurality of flat surface portions 111a, and the front side 1f of the base 1 is flattened.

[0031] In the base 1a, recesses 12a are formed between adjacent spherical portions 11a. That is, each recess 12a is formed by a constriction formed by adjacent spherical portions 11a. That is, each recess 12a is formed by approximately half of the curved surface of one of the adjacent spherical portions 11a on the side closer to the other spherical portion 11a, and approximately half of the curved surface of the other of the adjacent spherical portions 11a on the side closer to the one spherical portion 11a.

[0032] Specifically, each recess 12a is provided in a groove shape extending between the outer edge side 1o, the rear side 1r, and the inner edge side 1i of the base 1a. As a result, each recess 12a is formed in a semicircular groove shape. Therefore, a plurality of recesses 12a are arranged at intervals in the circumferential direction on the outer edge side 1o of the base 1a. The boundary portion (the deepest portion of the recess 12a) between adjacent spherical portions 11a has a cross section perpendicular to the extending direction of the recess 12a formed in an arc shape. In other words, the connection portion of the curved surfaces of adjacent spherical portions 11a is rounded.

[0033] The protrusion 2 is configured to protrude from the front side 1f of the flat base 1. That is, the protrusion 2 protrudes from the flat surface portion 111a toward the front side (X1 direction side).

[0034] The other configurations of the brush 100a are similar to those of the brush 100 described above.

[0035] Moreover, the effects of the second embodiment are similar to those of the first embodiment.
