Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hair-washing device, and more particularly to a hair-washing device having a number of protrusions that come into contact with hair and scalp during hair washing.

[0002]

[Prior art]

 Normally, hair is washed by applying shampoo to the hair and then rubbing the scalp with the fingertips of both hands. In addition, when washing a woman's long hair, an operation of moving the palm while rubbing the hair while holding the hair between the palms of both hands is also performed. As described above, the hair washing method using fingertips or palms is a primitive method that can be easily performed at any time, but it is also a method that places a burden on fingers and palms. In addition, there is a risk that the scalp may be damaged at the tip of the nail in the case of a woman with extended nails. In order to reduce such a burden during hair washing and damage to the scalp, various types of hair washing tools having a large number of protrusions that come into contact with the hair and the scalp are commercially available, such as general households, barbers, and beauty salons. Used in This type of hair-washing tool is usually composed of a main body on which a number of projections are planted, and a holding portion for holding the main body. The tip of the projection is brought into contact with the scalp. By rubbing while doing so, it is possible to achieve the same effect as a hair washing operation with a fingertip.

[0003]

[Problems to be solved by the invention]

 As described above, the conventional general hair-washing tool is based on the premise that hair is washed by rubbing the tip of the projection while making contact with the scalp. For this reason, although it has an effect on washing a short hair of a man or a woman near the scalp of a woman's hair, it cannot exert a sufficient effect on a long hair portion far from the scalp.

[0004] Therefore, an object of the present invention is to provide a hair-washing tool that can exert a sufficient effect on any kind of hair, regardless of age or gender, regardless of the length of the hair.

[0010]

[Embodiment of the invention]

 The hair washing tool according to the present invention is constituted by a combination of a pair of tools, a first tool 10 and a second tool 20. Each tool has a large number of projections planted on the bottom surface of the main body and a holding portion for holding the main body with one hand, but both have different shapes of the bottom surface of the main body. That is, the bottom surface of the first tool 10 is curved in a concave shape, while the bottom surface of the second tool 20 is curved in a convex shape. Therefore, the bottom surface of the first tool 10 and the bottom surface of the second tool 20 have a curved shape fitted to each other. Hereinafter, the present invention will be described based on the structure of a specific embodiment illustrating the present invention.

First, the structure of the first tool 10 will be described with reference to the top view of FIG. 1, the side view of FIG. 2, and the bottom view of FIG. As clearly shown in the side view of FIG. 2, the first tool 10 includes a main body 11, a holding portion 12, a bank 13, and a number of protrusions 14. The bottom surface of the main body 11 is concavely curved as shown. The holding portion 12 is a raised portion formed on the upper surface of the main body 11 to hold the main body 11. As shown in the top view of FIG. 1, the holding portion 12 has a shape suitable for being held by one hand and held. Actually, the main body 11 and the holding part 12 are united by molding a material such as a synthetic resin into a unitary structure. As shown in the bottom view of FIG. 3, the bank-like portion 13 is a molding member attached so as to surround the periphery of the bottom surface of the main body 11. As shown in FIG. 2, the protrusion 14 is a slender columnar structure, and is implanted on the bottom surface of the main body 11. In this example, as shown in the bottom view of FIG. 3, a total of 22 projections 14 are arranged so as to form a three-row squad, all of which appear circular when viewed from the bottom. As described above, each of the protrusions 14 is a columnar structure having a circular cross section, but has a larger diameter at the root side (upper part in FIG. 2) and a smaller diameter at the tip side (lower part in FIG. 2). The tip of the projection 14 has a rounded shape so that it does not damage the skin even when it comes into contact with the scalp and can apply a smooth friction force to the skin without resistance. I have.

On the other hand, the structure of the second tool 20 will be described based on a top view of FIG. 4, a side view of FIG. 5, and a bottom view of FIG. As clearly shown in the side view of FIG. 5, the second tool 20 includes a main body 21, a holder 22, a bank 23, and a number of protrusions 24. The bottom surface of the main body 21 is convexly curved as shown. The holding portion 22 is a raised portion formed on the upper surface of the main body 21 to hold the main body 21. As shown in the top view of FIG. 4, the holding portion 22 has a shape suitable for being held by one hand. Actually, the main body portion 21 and the holding portion 22 are fused as an integrated structure by molding a material such as a synthetic resin. As shown in the bottom view of FIG. 6, the bank 23 is a molding member attached so as to surround the periphery of the bottom of the main body 21. The projection 24 is a long and narrow columnar structure, like the projection 14 of the first tool 10, and is implanted on the bottom surface of the main body 21. In this example, as shown in the bottom view of FIG. 6, a total of 22 projections 24 are arranged so as to form a three-row squadron. This is the same as the arrangement of the protrusions 14 in the tool 10. Each of the projections 24 is also a columnar structure having a circular cross section, like the projection 14, and has a larger diameter at the base side (upper side in FIG. 5) and a smaller diameter at the tip side (lower side in FIG. 5). Its tip has a rounded shape.

FIG. 7 is a side sectional view of the first tool 10 shown in FIG. 1 cut along a cutting line 7-7, and FIG. 8 is a sectional view of the second tool 20 shown in FIG. It is a sectional side view cut | disconnected along -8. In each case, the cross section is hatched. As is apparent from the side sectional view of FIG. 7, the bottom surface of the main body 11 is concavely curved, and the root portion of each projection 14 is planted on the curved surface. In addition, since the lengths of the projections 14 are substantially equal to each other, the envelope surface at the tip of the projection in the first tool 10 forms a curved surface corresponding to the bottom surface of the main body 11. On the other hand, as can be seen from the side sectional view of FIG. 8, the bottom surface of the main body 21 is convexly curved, and the root of each projection 24 is planted on this curved surface. Moreover, since the lengths of the projections 24 are substantially equal to each other, the envelope surface of the tip of the projection in the second tool 20 forms a curved surface corresponding to the bottom surface of the main body 21.

As can be seen by comparing FIGS. 7 and 8, the curvature of the bottom surface of the body 11 of the first tool 10 and the curvature of the bottom of the body 21 of the second tool 20 are different from each other. Are set so as to be substantially equal, and the bottom surface of the main body portion 11 of the first tool 10 and the bottom surface of the main body portion 21 of the second tool 20 have a curved shape fitted to each other. . As a result, the envelope surface formed by the tips of the plurality of protrusions 14 shown in FIG. 7 becomes a gentle concave surface, and the envelope surface formed by the ends of the plurality of protrusions 24 shown in FIG. 8 becomes a gentle convex surface. The curvature of the surface is substantially equal to the curvature of the convex surface. The curvature of the bottom surface of the main body 11 of the first tool 10, in other words, the envelope formed by the tips of the plurality of protrusions 14 shown in FIG. It is preferable to set the ratio.

Next, a description will be given of a method of using the hair-washing tool according to the embodiment, and an effect unique to the present invention will be described. First, in the case of washing the hair of a short-haired man or the vicinity of the scalp of a woman's hair, the shampoo may be applied to the entire scalp, and the shampooing operation may be performed using only the first tool 10. For example, by grasping the holding portion 12 with the fingertip of the right hand, applying the tips of a number of protrusions 14 so as to contact the scalp, and moving the scalp with the tips of the protrusions 14 as it is, effective hair washing is possible. It will work. In particular, if the curvature of the bottom surface of the main body 11 is set to a curvature that substantially matches the surface of the head of the human body, the tips of the many protrusions 14 can be brought into uniform contact with the surface of the head. It is possible to perform efficient hair washing. Alternatively, a hair washing operation using only the second tool 20 is also effective. When the second tool 20 is used, the curved state is warped to the opposite side to the surface of the head, so that it is necessary to bring the tips of the many projections 24 into uniform contact with the surface of the head. It is inappropriate, but conversely, it is effective for intensive washing of localized areas of the head (for example, areas with severe itching).

On the other hand, when washing a portion of a woman's long hair away from the scalp, the hair is washed with a shampoo solution, and the hair washing operation using a combination of the first tool 10 and the second tool 20 is performed. It can be performed. For example, the first tool 10 is held by the right hand by holding the holding unit 12 with the fingertip of the right hand, and the second tool 20 is held by the left hand by holding the holding unit 22 with the fingertip of the left hand. Then, as shown in the side view of FIG. 9, the first tool 10 and the second tool 20 are held such that their bottom faces face each other, and the hair H to be subjected to hair washing (see FIG. In the case of, the direction perpendicular to the paper surface is the longitudinal direction of the hair, and the black circle indicates the cross section of the hair). In the figure, for the sake of convenience, the state where the tips of the projections 14 and 24 are separated from the hair H is shown, but in practice, the first tool 10 and the second tool 20 are moved closer to each other. If so, the hair H can be sandwiched between the projections 14 and the projections 24, and if the hairs H are further approached, the projections 14 and the projections 24 can be intersected. . In such a state, if the first tool 10 and the second tool 20 are moved in a direction perpendicular to the paper surface (a direction along the flow of the hair H), the protrusions 14 and 24 Moderate friction occurs between the hair and the hair H, and the hair-washing target portion can be effectively washed.

As described above, the curvature of the bottom surface of the main body 11 of the first tool 10 and the curvature of the bottom surface of the body 21 of the second tool 20 are set to be substantially equal. Since the bottom surface of the main body portion 11 of the first tool 10 and the bottom surface of the main body portion 21 of the second tool 20 have a curved shape that fits each other, the main body is not used in the usage form shown in FIG. The distance between the bottom surface of the portion 11 and the bottom surface of the main body portion 21 is substantially equal in each portion, and the distance between the envelope surface formed by the tips of the plurality of protrusions 14 and the envelope surface formed by the tips of the plurality of protrusions 24 is also substantially equal in each portion. Become equal. Therefore, the contact state of the hair H with the individual projections 14 and the individual projections 24 is also uniform at each part, and the hair washing operation can be performed while giving uniform friction to the hair H as a whole. become able to. In addition, since both envelope surfaces are curved, it is easy to keep the hair H sandwiched between them, and it is possible to prevent the hair H from escaping from the hair-washing tool.

As shown in the bottom view of FIG. 3 or FIG. 6, the periphery of the bottom surface of the first tool 10 and the periphery of the bottom surface of the second tool 20 each function as a molding. A bank 13 and a bank 23 are attached. Since the bank 13 and the bank 23 are lower than the protrusion 14 and the protrusion 44, the hair washing effect by the tip of the protrusion 14 or the protrusion 24 is not hindered. These bank-shaped portions 13 and 23 can exhibit the effect of storing and stopping shampoo liquid and foam on the bottom surfaces of the main body portion 11 and the main body portion 21, thereby further improving the effect of the present invention. Can be up.

As described above, the present invention has been described based on the specific embodiments illustrated in the drawings. However, the present invention is not limited to the embodiments, and can be implemented in various other forms. For example, the shape and size of the main body and the holding portion are not limited to those shown in the drawing, and the main body may have another shape as long as it can support a large number of protrusions. Similarly, the holding portion may have any shape as long as it is suitable for holding the main body portion with one hand. However, in practical use, it is preferable that the holding portion fits well in the palm and the distribution of gripping force is even. These materials are preferably synthetic resins such as various plastics from the viewpoint of manufacturing cost, but may be made of wood or metal. However, it is preferable to use as light a material as possible in order to reduce the burden of the hair washing operation.

Further, the protrusions are not limited to the above embodiment. For example, in the case of the above-described embodiment, a total of 22 projections 14 are formed on the first tool 10 in an arrangement as shown in FIG. A total of 22 projections 24 are formed in the arrangement shown in FIG. Here, when the arrangement of the respective projections is compared between the first tool 10 and the second tool 20, the arrangement of both is exactly the same. In this way, when the projections are implanted in exactly the same arrangement, as shown in FIG. 9, when the two are used in combination, the tip of the projection 14 and the tip of the projection 24 are located at the corresponding positions. Since they come into contact with each other, it is necessary to slightly shift their planar positions in order to bring them closer to each other so that the projections 14 and the projections 24 intersect. However, in practice, the hair-washing worker does not perform the hair-washing work while strictly aligning the first tool 10 and the second tool 20 in a two-dimensional manner. I don't care. For example, a second tool 20A whose bottom view is shown in FIG. 10 is a variation in which the number and arrangement of the projections 24 in the second tool 20 whose bottom view is shown in FIG. Instead of the second tool 20, a second tool 20A shown in FIG. 10 may be used.

As described above, the shape, size, number, and arrangement of the protrusions can be arbitrarily set, and various forms other than the above-described embodiment are possible. However, if the number and the density of the protruding portions are too high, the resistance to the hair H increases. Therefore, it is necessary to set an appropriate value in consideration of the ease of the hair washing operation. Further, it is preferable to use a material having elasticity and fitting without contact when it comes into contact with the scalp. Specifically, various plastics, natural rubber, synthetic rubber, and the like can be used. If the main body and the projection are made of the same material, both can be formed by integral molding.

In addition, by changing the shape, size, and material of the projection, the hardness of the projection itself can be changed, so that a plurality of types of hair-washing tools having different hardnesses are provided according to the application. It doesn't matter. For example, it is also possible to separately provide a product having a hard protruding portion for a general adult, a slightly softer product for a woman, and a softer product for an elderly or young person.

[0023]

[Effects of the Invention] As described above, according to the hair-washing tool according to the present invention, one of the tools has a concave bottom surface and the other has a convex bottom surface. For scalp scalp distant hair, effective hair washing is possible by using both face-to-face. Thus, the hair-washing device according to the present invention can exert a sufficient hair-washing effect on any type of hair, regardless of age or gender, regardless of the length of the hair. Further, the hair washing device according to the present invention can be used not only for washing one's own hair, but also for washing another person's hair. For example, it can be used to provide hair washing services to customers in barbers and beauty salons. Alternatively, it can be used when relatives and caregivers wash their hair for those who cannot wash their own hair, such as the elderly, children, and the sick. In particular, the elderly and sick people often have to wash their hair when they are bedridden.Therefore, the use of the hair washing device according to the present invention can significantly reduce the burden on caregivers and the like. In addition, a sufficient hair washing effect can be expected.
