Description

[Technical Field]

[0001] The present invention relates to a massage brush, and more particularly to a massage brush used for massaging and washing the body, washing hair, etc. [Background technology]

[0002] As a tool used for efficiently removing dirt from the scalp and hair during hair washing, a scalp washing tool with a plurality of flexible cleaning protrusions protruding from the main brush surface and held in one hand for washing is well known. Also, as a tool having a scalp massaging function in addition to the above-mentioned cleaning function, a massage brush is known, for example, as described in Japanese Utility Model Publication No. 58-188703 (Patent Document 1), in which long, needle-like protrusions suitable for washing hair are provided on one side of the brush body and thick, short protrusions suitable for scalp massage are provided on the other side.

[0003] In contrast to this, massage brushes such as those described in JP 2016-220976 A (Patent Document 2) are also widely used, in which the cleaning protrusions and the massaging protrusions are located in different positions on the same brush surface, allowing the scalp to be cleansed and massaged simultaneously or successively without changing the way the brush body is held.

[0004] Meanwhile, Utility Model Registration No. 3086423 (Patent Document 3) proposes a hair washing tool that consists of a pair of brush bodies with brush surfaces that have resin protrusions. The user holds one brush body in each hand and washes the hair by pinching it between the brush surfaces of both brush bodies, making it possible to wash hair more efficiently than the above-mentioned tools.

[0005] This hair washing tool is characterized by the fact that the cleaning surface of one brush body is formed concavely and the cleaning surface of the other brush body is formed convexly, and the curvature of both brushes matches, allowing the brush surfaces to face each other and be in close contact with each other to efficiently wash hair regardless of its length.In addition, it can be held in one hand and used to massage and wash with both hands at the same time.

[0006] However, this hair washing tool has the drawback that the manufacturing costs are high because the two brush bodies have different shapes, and because one of the cleaning surfaces is concave, it is prone to uneven cleaning and massaging effects when applied to different parts of the hair with both hands.Furthermore, although this hair washing tool is advantageous for storage in that the pair of brush bodies can be combined into one by bringing the two curved cleaning surfaces into close contact, the brush parts are exposed to the outside when they are combined into one, making the integrated appearance messy and untidy, which must be said to be a drawback in terms of aesthetics when stored. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Jitszen No. 58-188703 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-220976 [Patent Document 3] Utility Model Registration No. 3086423 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to solve the above-mentioned problems, and aims to provide a massage brush consisting of a pair of brush bodies, each of which can be used for massage or cleaning, and which, when combined, forms an integrated shape that is aesthetically pleasing. [Means for solving the problem]

[0009] Therefore, the present invention is a massage brush consisting of a combination of a pair of brush bodies, each having a brush surface with multiple synthetic resin protrusions protruding from it, which can be held in each hand when in use, and which can be stored by overlapping the brush surfaces of both brush bodies to form a single integrated shape, with multiple conical protrusions protruding from the brush surfaces at predetermined positions, and multiple insertion holes formed at corresponding positions into which the protrusions of the opposing brush surface can be inserted when the brush bodies are overlapped, and by integrating the pair of brush bodies, all of the protrusions fit into the insertion holes and are not exposed to the outside.

[0010] In this way, each brush surface of a pair of brush bodies, which become one unit when the brush surfaces are overlapped, is provided with a conical protrusion made of synthetic resin suitable for cleaning and massaging, and an insertion hole is provided in a corresponding position into which the protrusion of the other brush body is inserted when the brush bodies are overlapped.When the brush bodies are integrated, all the protrusions fit into the insertion holes but are not visible from the outside.This not only means that each of the pair of brush bodies can be used for cleaning and massaging, but also that when the brush bodies are stored combined, the protrusions are not visible from the outside, giving them an aesthetically pleasing, integrated shape.

[0011] Furthermore, if this massage brush is characterized in that the shape of the pair of brush bodies when stacked together is spherical, and all of the outer surfaces except for the joining line are spherical, not only will the massage brush have an even more aesthetically pleasing appearance when stored, but the spherical shape created by the integration will also allow it to be used for other purposes such as a massage ball.

[0012] Furthermore, if the above-mentioned massage brush is characterized in that the pair of brush bodies are made up of two resin molded products of the same shape and size, it is possible to combine the same parts made in the same mold to make a single product, making it easier to keep manufacturing costs low.

[0013] In this case, if the brush body is characterized by having an interlocking structure formed on the outer periphery of the brush surface, which tightly fits the outer edges of the brush surfaces of both brush bodies together and interlocks them so that the joining line when they are united creates a continuous uneven or wavy configuration that runs all the way around the outer periphery, not only will it be easier to maintain the united state, but when they are used separately, the uneven or wavy structure formed on the outer edge of the brush surface can also be used as a massaging protrusion, and even if there is a joining line due to this interlocking structure, the uniformity created by the continuous shape makes it less likely to detract from the aesthetic appearance when they are united. [Effects of the Invention]

[0014] According to the present invention, conical protrusions are provided on the brush surfaces of a pair of brush bodies, and insertion holes are provided into which the protrusions of the other brush body are inserted when the brush bodies are stacked, so that all protrusions fit into the insertion holes when the brush bodies are stored.In addition to being able to use each brush body for cleaning and massaging, combining the pair of brush bodies creates a unified shape that is aesthetically pleasing. [Brief explanation of the drawings]

FIG. [Figure 3] FIG. 3 is a plan view of the lower brush body of FIG. 2. [Figure 4] Cross-sectional view along line AA in Figure 1 (enlarged partial view in circle). DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the massage brush of the present invention is not limited to a brush used for massaging various parts of the body, but also includes a brush that can be used for washing various parts of the body and washing hair in addition to massage.

[0017] Fig. 1 shows a massage brush 1 according to this embodiment, and Fig. 2 is a perspective view of the massage brush 1 in Fig. 1 separated into two brush bodies 2, 2 in use. This massage brush 1 is made by integrally molding a relatively soft synthetic resin such as an elastomer resin, and is suitable for massaging and cleaning the body, including the head, and for washing hair.

[0018] 2, the massage brush 1 of this embodiment is composed of a combination of brush bodies 2, 2 each having a brush surface 10 with a plurality of conical projections 11, 12 made of synthetic resin suitable for use on human skin. When using this massage brush 1, the pair of brush bodies 2, 2 can be separated and held in each hand, and when storing, the brush surfaces 10, 10 of the two brush bodies 2, 2 can be placed together facing each other to form a spherical unit as shown in FIG.

[0019] As shown in Figure 2, the brush surface 10 of the approximately hemispherical brush body 2 has multiple conical protrusions 11, 12 protruding at predetermined positions, and multiple insertion holes 13, 14 are formed at predetermined positions into which the protrusions 11, 12 of the mating brush surface 10 are inserted when a pair of brush bodies 2, 2 are integrated.By overlapping the brush surfaces 10, 10 together, all of the protrusions 11, 12 are contained within the insertion holes 13, 14 and are not exposed to the outside, which is the greatest feature of the present invention.

[0020] That is, the brush surfaces 10, 10 of the pair of brush bodies 2, 2 are provided with conical protrusions 11, 12 made of soft resin suitable for washing and massaging at appropriate positions, and in addition, insertion holes 13, 14 are provided at corresponding positions into which all of the mating protrusions 11, 12 are inserted when the brush bodies 2, 2 are stacked together, so that when the brush bodies 2, 2 are stored as a single unit, all of the protrusions 11, 12 are stored within the insertion holes 13, 14 and cannot be seen from the outside.

[0021] Therefore, when the massage brush 1 is separated, each of the brush bodies 2, 2 can be used simultaneously for cleaning and massaging the body or washing hair. In addition, when the brush bodies 2, 2 are combined into a single unit and not in use (during storage), the two brush surfaces 10, 10 are in close contact with each other, and the cleaning surface and protrusions 11, 12, which tend to give a messy impression, are all hidden, resulting in an integrated shape that is aesthetically pleasing.

[0022] Furthermore, in this embodiment, as described above, the shape of the pair of brush bodies 2, 2 when stacked together is spherical (ball-shaped), and since the entire outer surface except for the wavy joint line is made up of a smooth spherical surface, when the massage brush 1 is stored and not in use it remains compact and has an extremely beautiful appearance.When it is in an almost perfectly spherical state, it can be used for other purposes, such as being used as a massage ball by pressing it against the waist or feet, or for playing with balls.

[0023] Another important feature of the massage brush 1 of this embodiment is that the pair of brush bodies 2, 2 that make it up are made of two resin molded products of the same shape and size. This allows it to be provided as a product made from a combination of identical parts made in a single mold, making it easy to keep manufacturing costs low.

[0024] In addition, as shown in FIG. 1, an interlocking structure is formed on the outer edge of the brush surface 10 of the brush body 2, which interlocks the outer edges of both brush bodies 2, 2 so that when the two are combined together, the joining line has a continuous wave-like shape around the outer periphery. This interlocking structure is formed by interlocking protrusions 10a and interlocking recesses 10b which are formed continuously around the circumferential direction.

[0025] This interlocking structure makes it easier to maintain the massage brush 1 in a stable state when it is united, and the continuous wave-shaped form on the outer edge of the brush surface 10, where the interlocking convex portion 10a sandwiches the interlocking concave portion 10b, can also be used as a massaging protrusion.Furthermore, because of this interlocking structure, the continuous wave-shaped joining lines form a unique pattern while adhering tightly without forming any gaps, so their presence is unlikely to detract from the aesthetic appearance when the brush is united.

[0026] 3 is a plan view showing the detailed configuration of the brush surface 10 of the brush body 2. In this brush surface 10, a combination of interlocking convex portions 10a and interlocking concave portions 10b is continuous along the outer peripheral surface on the outer edge side, and conical protrusions 11 and insertion holes 13 having a diameter and depth sufficient for inserting the protrusions 11 are arranged continuously in the circumferential direction on the inner peripheral side thereof, and conical protrusions 12 having a smaller diameter, thinner, and shorter than the protrusions 11 and insertion holes 14 having a diameter and depth sufficient for inserting the protrusions 12 are arranged continuously in the circumferential direction on the inner peripheral side thereof, and a substantially circular flat surface 10c is formed on the inner peripheral side thereof.

[0027] In this way, by adopting a configuration in which thin protrusions 12 are arranged in a circle near the center of brush surface 10 and thicker protrusions 11 are arranged in a circle on the outer periphery thereof, it is possible to use different parts of brush surface 10, for example, mainly for cleaning the hair and scalp at the center of brush surface 10 and mainly for massaging the scalp at the outer periphery thereof. Also, interlocking convex portions 10a with hemispherical tips arranged on the outer periphery of thick protrusions 11 can be used to perform a massage with a different effect than the pointed protrusions 11, 12 arranged on the inner periphery thereof.

[0028] Referring to the enlarged circular partial view of the longitudinal cross section of the massage brush 1 in Figure 4, the interlocking convex portion 10a and interlocking concave portion 10b that constitute the interlocking structure between the brush bodies 2,2 have a groove-like locking concave portion 100a formed horizontally on the inner surface of the interlocking convex portion 10a, and a ridge-like locking convex portion 100b formed horizontally on the outer surface of the interlocking concave portion 10b at the corresponding position; these engage with each other when the brush bodies 10,10 are united, thereby maintaining a state in which the two are difficult to separate.

[0029] The engagement between the engagement recess 100a and the engagement protrusion 100b is achieved by pulling the brush bodies 2, 2 strongly in the separation direction, which causes the resin material to elastically deform. However, since the engagement function is exerted along the entire circumference of the spherical massage brush 1, sufficient engagement force can be exerted even when using it as a massage ball or when playing with the ball.

[0030] As described above, with regard to a massage brush consisting of a pair of brush bodies, the present invention allows each brush body to be used for cleaning and massaging, and by combining the pair of brush bodies, it is possible to create an integrated shape that is aesthetically pleasing.
