Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor has studied making the structure of an application part such as a roller a structure in which a metal layer is formed on a resin base. Here, for example, by making the metal layer a single copper layer, the adhesion between the base and the metal layer can be improved, and the strength of the application part can be increased. However, if the metal layer is a single copper layer, there is a risk that problems such as the performance of the application part depending on the physical properties of copper may occur. Thus, there is a problem that it is difficult to achieve both an improvement in the strength of the application part and suppression of dependence on copper for an application part having a structure in which a metal layer is formed on a resin base. Note that such a problem is common to beauty devices having an application part, not limited to beauty rollers.

[0005] This specification discloses a technology capable of solving the above-described problems.

Means for Solving the Problems

[0006] The technology disclosed in this specification can be realized, for example, in the following forms.

[0007] (1) The beauty device disclosed in this specification is a beauty device having a treatment part, and the treatment part has a resin base and a metal layer containing copper formed on the surface of the base. The copper content in the metal layer is lower on the surface side of the treatment part than on the base side. In this beauty device, a metal layer containing copper, which has relatively high adhesion to the resin, is formed on the surface of the resin base of the treatment part. The copper content in this metal layer is lower on the surface side of the treatment part than on the base side. Therefore, for example, compared with the case where the copper content on the surface side of the treatment part in the metal layer is as high as that on the base side in the metal layer, the dependence on copper in the treatment part can be suppressed. That is, according to this beauty device, the strength of the treatment part can be increased while suppressing the dependence on copper.

[0008] (2) In the above beauty device, the metal layer may have a first metal layer formed on the surface of the base and a second metal layer formed on the surface of the first metal layer, and the copper content in the second metal layer may be lower than the copper content in the first metal layer. In this beauty device, the second metal layer is formed on the surface of the resin base of the treatment part via a first metal layer made of copper, which has relatively high adhesion to the resin. Also, since the second metal layer also contains copper, the adhesion between the second metal layer and the first metal layer is high. Therefore, each layer constituting the treatment part is difficult to peel off, and the strength of the treatment part can be increased.

[0009] (3) In the above beauty device, the second metal layer may be an alloy layer containing copper and other metals. According to this beauty device, since the hardness of the second metal layer increases, the hardness of the treatment part of the beauty device is improved, so that it is possible to suppress the deformation of the surface of the treatment part, for example, the occurrence of dents and the like.

[0010] (4) In the above-described beauty device, the other metal may be a metal having a standard electrode potential more negative than that of the copper (for example, zinc or tin). According to this beauty device, even if the second metal layer is damaged, a film is formed by the other metal contained in the second metal layer, so that corrosion of the first metal layer, which is the base layer, can be suppressed.

[0011] (5) In the above-described beauty device, the second metal layer may be configured as a copper-tin alloy layer. According to this beauty device, compared with a configuration in which the second metal layer is, for example, a copper-zinc alloy layer, the hardness of the treatment part of the beauty device is improved, so that the surface of the treatment part is deformed, for example, dents or the like can be effectively suppressed from occurring.

[0012] (6) In the above-described beauty device, the copper content in the copper-tin alloy layer may be 60 wt% or more and 80 wt% or less. According to this beauty device, since the hardness of the treatment part is improved, deformation of the surface of the treatment part, for example, dents or the like can be effectively suppressed from occurring.

[0013] (7) In the above-described beauty device, the treatment part may further have a platinum group element layer formed on the second metal layer and constituting the outermost surface of the treatment part. According to this beauty device, since the outermost surface of the treatment part is formed of a platinum group element layer, the glossiness can be improved while ensuring the strength of the treatment part.

[0014] (8) In the above-described beauty device, the platinum group element layer may have a palladium layer formed on the second metal layer and a platinum layer formed on the palladium layer. According to this beauty device, the platinum layer is formed on the second metal layer via a palladium layer having high adhesion to the second metal layer. Therefore, each layer constituting the treatment part is difficult to peel off, and the glossiness of the treatment part can be improved while increasing the strength of the treatment part.

[0015] Note that the technology disclosed in this specification can be realized in various forms, for example, in the form of a beauty device and its manufacturing method, etc.

Mode for Carrying Out the Invention

[0017] A. Embodiment: A-1. Configuration of the beauty roller 100: FIG. 1 is an explanatory drawing schematically showing the configuration of the beauty roller 100 in the embodiment. The beauty roller 100 is an example of the beauty device in the claims.

[0018] The beauty roller 100 includes a roller 10 and is used, for example, by applying the roller 10 to the skin and rolling it. When the beauty roller 100 is used on the face, the facial line around the jaw is tightened and a lifting effect can be felt. In the case of the beauty roller 100 of the type including a plurality of rollers 10 as in this embodiment, there is also a massage effect in which the plurality of rollers 10 pick up the skin. More proactively, if the beauty roller 100 is used in the manner of a lymphatic massage, the excretion of waste products is promoted, metabolism is increased, and skin texture can be improved. If it is used on the legs, swelling and cellulite can be easily removed.

[0019] As shown in FIG. 1, the beauty roller 100 includes a pair of rollers 10 and a grip 20.

[0020] The grip 20 has a grip portion 22 and a pair of support portions 24. The grip 20 is a portion that the user grips when using the beauty roller 100 and is formed in a substantially ellipsoidal shape. The pair of support portions 24 are formed so as to branch off from the tip of the grip portion 22 and extend. The grip 20 is formed of, for example, resin.

[0021] Each roller 10 is a rotating body rotatably supported by each support portion 24 of the grip 20. The shape of the roller 10 is substantially spherical. Note that the shape of the roller 10 is not limited to substantially spherical, and may be, for example, substantially ellipsoidal, substantially cylindrical, or substantially balloon-shaped. The roller 10 is an example of the treatment portion in the claims.

[0022] A-2. Internal Structure of Roller 10: FIG. 2 is an explanatory diagram schematically showing the internal structure of the roller 10. On the right side of FIG. 2, the cross-sectional structure of the roller 10 at the position II-II of FIG. 1 is shown, and on the left side of FIG. 2, an enlarged view schematically showing a portion X1 in the cross-sectional structure of the roller 10 is shown.

[0023] As shown in FIG. 2, the roller 10 has a structure in which a coating layer 13 is formed on a substantially spherical base 12. The base 12 is formed of a resin material such as synthetic resin, and in this embodiment, is formed of ABS resin. The coating layer 13 is composed of a metal layer 14 containing copper (Cu) and a platinum group element layer 16.

[0024] The metal layer 14 is a layer formed on the surface of the base 12 so as to cover the entire surface of the base 12. The copper content (wt%) in the metal layer 14 is lower on the surface side of the roller 10 than on the base 12 side. Specifically, the metal layer 14 has a copper layer 14A and a copper-tin (Cu-Sn) alloy layer 14B.

[0025] The copper layer 14A is formed on the surface of the base 12 so as to cover the entire surface of the base 12. The copper layer 14A is formed of copper. The copper content in the copper layer 14A is substantially 100% (it may contain impurities). The copper layer 14A is an example of the first metal layer in the claims.

[0026] The alloy layer 14B is formed on the surface of the copper layer 14A so as to cover the entire surface of the copper layer 14A. The content ratios of copper and tin in the alloy layer 14B are substantially 100% (which may include impurities). Since the alloy layer 14B contains tin in addition to copper, the content ratio of copper in the alloy layer 14B is lower than the content ratio of copper in the copper layer 14A. The content ratio of copper in the alloy layer 14B is 60 wt% or more and 80 wt% or less, more preferably 65 wt% or more and 75 wt% or less. In the present embodiment, in the alloy layer 14B, the content ratio of copper is 70 wt% and the content ratio of tin is 30 wt%. Tin is a metal with a standard electrode potential more negative than that of copper. Note that the alloy layer 14B may contain other metals (for example, several %) in addition to copper and tin as long as it exhibits such effects. The alloy layer 14B is an example of the second metal layer in the claims, and tin is an example of the other metal in the claims.

[0027] As described above, due to the two-layer structure of the metal layer 14 including the copper layer 14A and the alloy layer 14B, the content ratio of copper in the metal layer 14 is lower on the surface side of the roller 10 than on the base 12 side.

[0028] The platinum group element layer 16 is the layer constituting the outermost surface of the roller 10. The platinum group element layer 16 has a palladium layer 16A and a platinum layer 16B. The palladium layer 16A is formed on the surface of the alloy layer 14B so as to cover the entire surface of the alloy layer 14B. The content ratio of palladium (Pd) in the palladium layer 16A is substantially 100% (which may include impurities). The platinum layer 16B is formed on the surface of the palladium layer 16A so as to cover the entire surface of the palladium layer 16A. The content ratio of platinum (Pt) in the platinum layer 16B is substantially 100% (which may include impurities).

[0029] The thickness of the copper layer 14A is, for example, 3 μm or more and 40 μm or less, more preferably 15 μm or more and 25 μm or less, and the thickness of the alloy layer 14B is, for example, 1 μm or more and 10 μm or less, more preferably 2 μm or more and 4 μm or less. The thickness of the palladium layer 16A is, for example, 0.02 μm or more and 0.3 μm or less, more preferably 0.05 μm or more and 0.2 μm or less, and the thickness of the platinum layer 16B is, for example, 0.005 μm or more and 0.3 μm or less, more preferably 0.01 μm or more and 0.2 μm or less. Also, the thickness of the metal layer 14 is preferably greater than the thickness of the platinum group element layer 16, and the thickness of the copper layer 14A is preferably greater than the thickness of the alloy layer 14B. The thickness of the copper layer 14A is preferably the thickest among the plurality of layers constituting the metal layer 14, and the thickness of the copper layer 14A is preferably the thickest among the plurality of layers constituting the coating layer 13. The alloy layer 14B is preferably thicker than the thickness of each layer (palladium layer 16A, platinum layer 16B) constituting the platinum group element layer 16. Also, the thickness of the palladium layer 16A is preferably the same as or greater than the thickness of the platinum layer 16B.

[0030] A-3. Method for manufacturing the roller 10: The roller 10 is manufactured, for example, as follows. A predetermined pretreatment (etching, etc.) is performed on the surface of the base 12, and after electroless copper plating is performed, electrolytic copper plating is performed to form the copper layer 14A. By performing electroless copper plating first, variations in the thickness of the copper layer 14A can be suppressed. Next, an alloy plating of copper-tin is performed on the surface of the copper layer 14A to form the alloy layer 14B. Next, palladium plating is performed on the surface of the alloy layer 14B to form the palladium layer 16A. Next, platinum plating is performed on the palladium layer 16A to form the platinum layer 16B. Thereby, the manufacturing of the roller 10 is completed.

[0031] A-4. Effects of this embodiment: As described above, in the beauty roller 100 according to the present embodiment, on the surface of the resin base 12, a metal layer 14 containing copper, which has relatively high adhesion to the resin, is formed on the roller 10. The copper content in this metal layer 14 is lower on the surface side of the roller 10 than on the base 12 side (see FIG. 2). Therefore, for example, compared with a configuration in which the copper content on the surface side of the roller 10 in the metal layer 14 is as high as that on the base 12 side in the metal layer 14, the performance of the roller 10 (for example, the hardness of the surface of the roller 10) is less dependent on copper. That is, according to the present embodiment, it is possible to increase the strength of the roller 10 while suppressing the dependence on copper. Further, for example, compared with a configuration in which the metal layer (coating layer 13) is a single copper layer, the degree of freedom in the layer design of the roller 10 is high.

[0032] In the present embodiment, an alloy layer 14B is formed on the surface of the resin base 12 of the roller 10 via a copper layer 14A having relatively high adhesion to the resin. Further, since the alloy layer 14B also contains copper, the adhesion between the alloy layer 14B and the copper layer 14A is high. Therefore, each layer constituting the roller 10 is less likely to peel off, and the strength of the roller 10 can be increased.

[0033] In the present embodiment, the layer formed on the surface of the copper layer 14A is the alloy layer 14B. Therefore, compared with a configuration in which the layer formed on the surface of the copper layer 14A is, for example, a synthetic layer of copper and a material other than metal (for example, resin), since the hardness of the alloy layer 14B is increased, the hardness of the roller 10 of the beauty roller 100 is improved, so that it is possible to suppress deformation of the surface of the roller 10, for example, the occurrence of dents and the like. Thereby, for example, it is possible to suppress the deterioration of the usability of the roller 100 (roller 10) due to the occurrence of dents and the like.

[0034] In this embodiment, the alloy layer 14B contains tin, which is a metal with a standard electrode potential more negative than that of copper. Therefore, even if the platinum group element layer 16 or the alloy layer 14B is damaged, the corrosion of the copper layer 14A, which is the base layer, can be suppressed by the self-healing property in which a film is formed by the tin contained in the alloy layer 14B. Further, compared with a configuration in which the alloy layer 14B is, for example, a copper-zinc alloy layer, the hardness of the roller 10 of the beauty roller 100 is improved, so that the surface of the roller 10 is deformed, and the occurrence of dents, scratches, etc. can be effectively suppressed. Furthermore, the copper content in the alloy layer 14B is 60 wt% or more and 80 wt% or less. Therefore, since the hardness of the roller 10 is improved, the surface of the roller 10 is deformed, and for example, the occurrence of dents, scratches, etc. can be effectively suppressed.

[0035] In this embodiment, since the outermost surface of the roller 10 is formed of the platinum group element layer 16, the glossiness can be improved while ensuring the strength of the roller 10. Further, a platinum layer 16B is formed on the alloy layer 14B via a palladium layer 16A having high adhesion to the alloy layer 14B. Therefore, each layer constituting the roller 10 is difficult to peel off, and the glossiness of the roller 10 can be improved while increasing the strength of the roller 10. Note that by making the outermost layer of the roller 10 the platinum layer 16B, the oxidation resistance and heat resistance of the roller 10 can be improved.

[0036] B. Modification example: The technology disclosed in this specification is not limited to the above-described embodiment, and can be modified into various forms without departing from the gist thereof. For example, the following modifications are also possible.

[0037] The configuration of the beauty roller 100 in the above embodiment is merely an example, and various modifications are possible. For example, the shape, dimensions, forming material, and manufacturing method of each part in the beauty roller 100 of the above embodiment are merely examples, and various modifications are possible. In the above embodiment, the beauty roller 100 includes a pair of rollers 10, but the number of rollers 10 included in the beauty roller 100 may be one or three or more.

[0038] In the above embodiment, the roller 10 has a structure in which the metal layer 14 covers the entire surface of the base 12. However, for example, a structure in which the metal layer 14 covers only a part of the surface of the base 12 may also be used. In the above embodiment, a two-layer metal layer 14 having a copper layer 14A and an alloy layer 14B is exemplified as the metal layer. However, for example, the following layers may also be used. (1) A multilayer metal layer having three or more layers containing copper, and the closer the layer is to the surface side of the roller 10, the lower the copper content. (2) A metal layer in which the copper content continuously (steplessly) decreases as it approaches the surface side of the roller 10.

[0039] In the above embodiment, a copper-tin alloy layer 14B is exemplified as the alloy layer. However, for example, a copper-zinc (Cu-Zn) alloy layer or the like may also be used. Further, in the above embodiment, tin is exemplified as the other metal. However, it is not limited to tin, and any metal having a standard electrode potential more negative than copper (for example, zinc) can suppress the corrosion of the copper layer 14A due to self-recovery.

[0040] In the above embodiment, a palladium layer 16A or a platinum layer 16B is exemplified as the platinum group element layer. However, a layer containing other platinum group elements (ruthenium (Ru), rhodium (Rh), osmium (Os), iridium (Ir)) may also be used.

[0041] In the above embodiment, a configuration in which another layer (for example, a metal layer) is disposed between the metal layer 14 and the platinum group element layer 16 may also be used. Further, in the above embodiment, the platinum group element layer 16 may be omitted, and the metal layer 14 may constitute the outermost surface of the roller 10.

[0042] The beauty roller 100 according to the above embodiment may be configured to have a function of generating an electric current that flows from the surface of the roller 10 to the body (such as the skin). The generated electric current is, for example, a weak current called a microcurrent for enhancing skin metabolism, an ion introduction current for allowing charged beauty components to penetrate from the skin surface into the skin, or an ion extraction current for causing charged dirt components such as dirt in pores to rise from the inside of the skin to the skin surface. Specifically, for example, the grip 20 has a built-in power supply unit such as a battery or a power generation device (such as the solar panel 23 in FIG. 1), and the power supply unit is electrically connected to the metal layer (coating layer 13) of the roller 10, and an electric current flows from the power supply unit to the metal layer (platinum layer 16B) that constitutes the surface of the roller 10. Thus, in the beauty device in which the treatment part has electrical performance, in particular, it is preferable to have a structure in which a metal layer is formed on a resin base. By applying the present invention, it is possible to suppress the dependence on copper while increasing the strength of the roller 10.

[0043] In the above embodiment, the beauty roller 100 is exemplified as the beauty device. However, the present invention can be applied to any beauty device having a treatment part. The treatment part may be any part of the beauty device that comes into contact with the user, and is not limited to a rotating body. Herein, "coming into contact with the user" includes not only directly contacting the user's skin but also contacting the user from above the clothes the user is wearing.

[0044] FIG. 3 is an explanatory diagram schematically showing the external configuration of the beauty device 200 of the modified example. The beauty device 200 includes a contact portion 210 as an application portion, and presses the contact portion 210 against the skin and slides it slowly along the skin to pull it up or slide it down to massage the skin. Specifically, the beauty device 200 includes a contact portion 210 and a main body portion 220. The main body portion 220 is a portion that the user grips. The main body portion 220 has a generally flat heart-shaped shape as a whole. The contact portion 210 is formed so as to cover a part of the outer periphery of the main body portion 220 when viewed in a direction orthogonal to the main body portion 220. The contact portion 210 has a first contact portion 212 extending in an arc shape and a second contact portion 214 curved so as to have a pair of protruding portions. The internal structure of the contact portion 210 of such a beauty device 200 may be the same as that of the roller 10 of the above-described embodiment, that is, a structure in which a metal layer 14 and a platinum group element layer 16 are formed on a base 12 (see FIG. 2). Thereby, regarding the contact portion 210 of the beauty device 200, it is possible to suppress the dependence on copper while increasing the strength of the contact portion 210.
