Description

TECHNICAL FIELD

[0001] The present disclosure relates to a cartridge-replaceable shaver (hereinafter, simply referred to as a shaver) capable of replacing only a cartridge unit. BACKGROUND

[0002] In the past, in Patent Document 1, a replacement shaver capable of replacing only a cartridge unit in which a plurality of blades are integrated is disclosed.

[0003] The replacement shaver is provided with a holder having a grip portion and a head portion, and a shaver head having a cartridge member that houses a cartridge unit and a cover member. The cartridge member and the cover member are supported to the lower end of the head portion of the holder in a swingable manner by a support shaft. A locking claw portion is provided at the upper end of the cover member, and the cover member and the cartridge member are capable of opening and closing by being hooked to a locking shaft portion provided at the upper end of the cartridge member. In addition, two locking claw portions are provided at the upper end of the cartridge member, and the cartridge member and the head portion of the holder are capable of opening and closing by being hooked to a locking recess portion provided at the upper end of the head portion of the holder. Further, a permanent magnet that magnetically attracts the cartridge unit is provided inside the head portion of the holder.

[0004] In the replacement shaver of such a configuration, when the two locking claw portions are unhooked from the locking recess portion to open the cartridge member and the head portion of the holder, the head portion becomes in a swingable state and the cartridge unit is separated from the permanent magnet. Therefore, when the locking claw portion is unhooked from the locking shaft portion to open the cover member and the cartridge member in this state, the cartridge unit can be easily detached. In addition, when the cartridge member and the cover member are opened while the cartridge member and the head portion of the holder are closed, the permanent magnet becomes in a state where it can abut against the cartridge unit, and thus the cartridge unit can be easily installed by being attracted to the permanent magnet.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2010-131228 SUMMARY

[0008] PROBLEMS TO BE SOLVED BY THE INVENTION

[0009] However, in the above-described replacement shaver, the cover member and the cartridge member are separately installed to the lower end of the head of the holder in a swingable manner, and a mechanism capable of separately opening and closing the cover member and the cartridge member and opening and closing the cartridge member and the head portion of the holder is required. Therefore, the configuration of the shaver head becomes complicated.

[0010] An object of the present disclosure is to provide a shaver capable of replacing only a cartridge unit while being configured simply.

[0011] Means for solving the problem

[0012] To achieve the above object, a first invention is a razor having a handle (2) extending in one direction and a razor head (1) mounted to a front end portion (50) of one side in the one direction in the handle, wherein the razor head has a blade body portion (10) provided with a blade body (11) having a length direction in a direction intersecting the one direction, a support body (20) coupled to the front end portion of the handle, having a placement surface (220) on which the blade body portion is placed in a state in which a blade tip of the blade body faces a side coupled to the handle, and a cover portion (30) that holds the blade body portion together with the support body while exposing the blade body, mounted to the support body, the razor being an all-metal body in which the support body, the cover portion, and the handle are made of metal, and in which the cover portion can be detached from the support body, and only the blade body portion can be replaced.

[0013] Thus, by being an all-metal body, a razor having a sense of thickness can be provided. In addition, in a razor in which the blade body is exposed from the cover portion, a structure having a sense of unity such as an all-metal body can be achieved, and the design is simple and attractive, and a product having a high-class feel can be achieved. In addition, the blade body portion can be easily detached from the support body simply by detaching the cover portion. Thus, only the blade body portion can be replaced.

[0014] Further, for example, the blade body portion is replaced when the blade body becomes dull, but the other portions (the handle, the cover portion, and the support body) are not replaced and are used for a long period of time, and thus it is expected that waste can be suppressed. Therefore, in addition to improving the durability of each component by metal, an attractive and high-class product is achieved, and thus the user can use it for a long period of time, and this contributes to the suppression of waste.

[0015] Further, since only the blade body portion can be replaced, the replacement can be minimized as needed, waste is reduced, and the target 12.5 of the target 12 of the SDGs, “Sustainable Production and Consumption”, “Substantially reduce waste through the prevention, reduction, recycling, and reuse of waste by 2030.” is met.

[0016] In the second invention, among the support body, the cover portion, and the handle, the surface exposed to the outside is a mirror surface. By making the surface exposed to the outside a mirror surface, the razor can have a sharp and glossy appearance of the metal surface, and can have a structure that is easy to clean and easy to maintain. In addition, the razor can have a smooth and comfortable touch, and can also provide a smooth and comfortable touch to the part of the mirror surface in the cover portion in contact with the skin while shaving with the blade body.

[0017] In the third invention, the cross-sectional shape of the handle in a direction normal to the direction is circular or a shape in which the corners of a polygon are rounded. By providing the handle in such a shape, a more simple design can be achieved, and a shape that is easy to hold during use can be achieved.

[0018] In the fourth invention, the handle is tapered in shape such that the cross-sectional area gradually decreases from the rear end portion side, which is opposite the front end portion, toward the front end portion side. By providing the handle in such a tapered shape, a shape can be achieved in which the connecting portion to the razor head is thin while the rear end portion is thick, and the base portion is thick. Thus, the handle can be made in a simple design while achieving a shape that is easy to hold during use.

[0019] In the fifth invention, the handle is solid. Thus, the razor can have a more substantial weight, and the rigidity of the product can be improved.

[0020] In the sixth invention, a stand (500) is provided, which is a bottomed cylindrical shape having a side surface and a bottom surface, and which holds the razor body replacement razor by inserting the rear end portion, which is opposite the front end portion, of the handle into the hollow portion (503) formed by the side surface (501) and the bottom surface (502). The stand has one surface formed along the insertion direction of the handle, and a holding magnet (506) is provided on the one surface, which magnetically attracts the stand to the magnetic member.

[0021] By providing the stand in such a structure, the razor can be easily stored by simply inserting the razor into the stand. In addition, the stand can be provided by magnetically attracting the holding magnet to a wall surface or the like formed of a magnetic member, and the storage position of the razor can be ensured, so that it is not necessary to ensure the storage position on a washstand or the like. In addition, since the stand is provided to the magnetic member by the magnetic attraction force of the holding magnet, the stand can be easily detached and moved, and in addition, unlike a structure in which the attraction force can gradually decrease, such as a suction cup, the stand can be provided for a long period of time.

[0022] In addition, in the case where the razor is provided as a full metal body such that the surface exposed to the outside is a mirror surface, it is preferable to provide the surface exposed to the outside of the stand as a mirror surface. In this way, the stand can be provided as a metallic surface that is sharp and has a glossy appearance, and can be provided as a structure that is easy to clean and easy to maintain clean. In addition, it is possible to provide a good tactile sensation. Furthermore, it is possible to provide a unified feeling with the main body of the razor, and it is possible to further improve the design.

[0023] In addition, the bracketed reference numerals attached to each of the constituent elements and the like indicate an example of the correspondence relationship between the constituent elements and the like and the specific constituent elements and the like described in the embodiments described below.

[0057] Structure of shaver head 1

[0058] The shaver head 1 is a portion that constitutes a shaving portion in the shaver S. The shaver head 1 is elliptical in shape with the X-axis direction as the minor axis and the Y-axis direction as the major axis, and is configured to have a prescribed thickness as the dimension in the Z-axis direction. Furthermore, both the head surface that is the surface side of the shaver head 1 and the head back surface that is the opposite side thereof are rounded in shape with rectangular outer edges in the Z-axis direction that is the thickness direction of the shaver head 1. Thus, the shaver head 1 is rounded in shape while constituting the shaving portion. Specifically, the shaver head 1 includes a shaver body portion 10, a support body 20, and a cover portion 30.

[0059] Structure of shaver body portion 10

[0060] The shaver body portion 10 is a replaceable component in the shaver S, and is configured to be attached to the support body 20 of the shaver S. Figure 6 As shown in Figs. 1 to 9, the shaver body portion 10 is configured by a shaver body 11, a blade table member 12, and a frame 13. These shaver body 11, blade table member 12, and frame 13 are all made of metal.

[0061] As shown in Figs. 1 to 9, the shaver body portion 10 is configured by a shaver body 11, a blade table member 12, and a frame 13. These shaver body 11, blade table member 12, and frame 13 are all made of metal. Figure 8AAs shown, the blade body 11 is formed in a rectangular shape with the Y-axis direction as the length direction, and a plurality of pieces, in this case, five pieces, are arranged and disposed in the X-axis direction in a state inclined at a prescribed angle with respect to the X-axis orthogonal to the length direction. A blade tip 11a is formed in each blade body 11, and as shown in Figure 1 As shown, the blade tip 11a of each blade body 11 faces the lower side of the side connected to the handle 2, and a plurality of blade bodies 11 are arranged at equal intervals with each blade tip 11a. Therefore, shaving can be performed by moving the shaving head 1 toward the lower side. Hereinafter, the direction in which the shaving head 1 is moved when shaving, that is, the direction of the lower side, is referred to as the shaving direction.

[0062] The blade stand member 12 is a member in which a plurality of blade bodies 11 are integrated by welding or the like. The blade stand member 12 has a spring configuration, and based on the elastic force generated by the spring configuration, the contact with the skin at the time of shaving is moderated, and the blade body 10 is prevented from shaking when the blade body 10 is sandwiched between the support body 20 and the cover 30. As shown in Figure 8A Figure 8B and Figure 9B As shown, the blade stand member 12 has a setting stand portion 121, a leg portion 122, a support portion 123, and a leaf spring portion 124.

[0063] The setting stand portion 121 is a base stand in which a plurality of blade bodies 11 are set, has a plurality of joint portions 121a arranged in a stepped shape, and is configured to be connected to the plurality of joint portions 121a by the support portion 123. Each joint portion 121a is provided along the Y-axis and is provided in a straight line shape corresponding to the blade body 11. Furthermore, in each joint portion 121a, the surface that is the joint surface of the blade body 11 is a flat surface, and the surfaces are arranged in the X-axis direction in a manner in which the surfaces are parallel to each other. The surface of each joint portion 121a is inclined with respect to the XY plane, and each blade body 11 is integrated with the setting stand portion 121 in a state inclined with respect to the XY plane by spot welding one piece of the blade body 11 to each joint portion 121a.

[0064] The leg portion 122 is a straight line-shaped member arranged along the Y-axis and is arranged on both the upper and lower sides across the setting stand portion 121. Like each joint portion 121a, each leg portion 122 is provided along the Y-axis. Each leg portion 122 is located at a position closer to the frame 13 than the setting stand portion 121 in the Z-axis direction, and the leaf spring portion 124 is connected to both ends of each leg portion 122 in the Y-axis direction.

[0065] ​The support portion 123 extends in the X-axis direction in a manner that intersects with each joint portion 121a and each foot portion 122, connecting each joint portion 121a and each foot portion 122. Multiple support portions 123 are provided, specifically four in this case, with the inner two positioned corresponding to the first frame portion 131 described later in the frame 13. The support portion 123 is curved such that the joint portions 121a are arranged in a stepped manner, and at the portions connecting with each foot portion 122, the foot portion 122 is curved such that it is positioned on the back side of the joint portion 121a.

[0066] The leaf spring 124 is configured such that both ends of each foot 122 bend toward the side opposite to the blade body 11. When a force is applied in the Z-axis direction, the leaf spring 124 undergoes elastic deformation to generate an elastic reaction force. The front end of the leaf spring 124 protrudes toward the back side of the frame 13, and when the blade body 10 is mounted on the support 20, the front end of the leaf spring 124 contacts the mounting surface 220 of the support 20.

[0067] Furthermore, the tool holder component 12 is formed, for example, by stamping a sheet of metal. Figure 8B As shown, each joint 121a is connected by a support 123. However, if a bent portion 121b, which is different from the support 123, is punched and bent towards the back side and kept connected to the joint 121a, the joint 121a can be strengthened. Even in this case, as long as the support 123 is formed at a position corresponding to the first frame portion 131 of the frame 13, interference between the bent portion 121b and the frame 13 can be avoided.

[0068] The frame 13 is the part that holds the tool body 11 and the tool holder component 12 and is magnetically attracted or magnetically attached by the support 20 (described later). For example... Figure 8B , Figure 9C As shown, the frame 13 has a first frame portion 131 and a second frame portion 132. These first frame portions 131 and second frame portions 132 are an integral part, and both the surface side and the back side are planar, for example, formed by stamping or metal forming of sheet metal.

[0069] The first frame portion 131 is a four-cornered frame shape and is the part that joins the tool holder member 12. Specifically, the first frame portion 131 is composed of an upper beam portion 131a and a lower beam portion 131b forming opposite sides of one side along the Y-axis direction, and a right beam portion 131c and a left beam portion 131d forming opposite sides of the other side along the X-axis direction. The tool holder member 12 is fixed to the frame 13 by engaging each foot portion 122 on the surface of the upper beam portion 131a and the lower beam portion 131b, and by arranging support portions 123 on the right beam portion 131c and the left beam portion 131d. The tool body 11 is also fixed to the frame 13 via the tool holder member 12.

[0070] The second frame portion 132 is elliptical in shape and is connected to the first frame portion 131 on its inner side. Specifically, the second frame portion 132 is composed of an upper beam portion 132a, a lower beam portion 132b, a right semicircular beam portion 132c, and a left semicircular beam portion 132d. The upper beam portion 132a and the lower beam portion 132b are respectively connected to the upper beam portion 131a and the lower beam portion 131b of the first frame portion 131. The right semicircular beam portion 132c and the left semicircular beam portion 132d are respectively arranged to extend outwards from the right beam portion 131c and the left beam portion 131d of the first frame portion 131. The second frame portion 132 is generally elliptical in shape, but at the center of the upper beam portion 132a, it protrudes outwards to the side opposite to the first frame portion 131, and this protruding part constitutes the first gripping portion 133.

[0071] Furthermore, an opening 134 is formed on the inner side of the first frame portion 131, an opening 135 is formed between the right beam portion 131c and the right semi-circular beam portion 132c, and an opening 136 is formed between the left beam portion 131d and the left semi-circular beam portion 132d. By forming these openings 134 to 136, interference between the bent portion 121b and the frame 13 is suppressed.

[0072] [Structure of support body 20]

[0073] like Figure 10 As shown, the support body 20 is a component that connects to one end of the shank 2 and supports the blade body 10 and the cover 30. The support body 20 has a generally elliptical shape when viewed from the surface, with its major axis aligned along the Y-axis and its minor axis aligned along the X-axis. Furthermore, it is connected to the shank 2 at the center of the lower side of the elliptical shape. Specifically, as... Figure 6 , Figure 7 As shown, the support body 20 has a back panel 21, a housing 22, a magnet 23, a magnet bracket 24, a spring 25, and a screw 26. Furthermore, the support body 20 is one of the components constituting the blade of the razor S. The back panel 21, housing 22, and other parts of the support body 20 that are exposed to the outside are made of metal, and the exposed surfaces are mirror-like.

[0074] The back panel 21 is the part that forms the back side of the razor head 1. For example... Figure 11A As shown, the back panel 21 has a generally elliptical shape when viewed from the surface side. The back panel 21 has an outer peripheral wall 211 along the outer edge of the elliptical shape, and an elliptical recess 212 is formed on the inner side of the outer peripheral wall 211, which is recessed from the surface side toward the back side. A part of the outer casing 22 is disposed in the recess 212.

[0075] In the upper central position in the back panel 21, a portion of the outer peripheral wall 211 is cut away to form a groove portion 213. This groove portion 213 is formed in a position corresponding to the first gripping portion 133 of the frame 13 described above and the second gripping portion 31a of the cover portion 30 described later, and is provided so that the first gripping portion 133 and the second gripping portion 31a protrude from the groove portion 213 when the shaver head 1 is viewed from the back side as shown in Figure 5 the drawing.

[0076] In addition, in the lower central position in the back panel 21, a portion of the outer peripheral wall 211 is also cut away to form a semicircular-shaped connecting recess portion 214. The front end of the handle portion 2 is disposed in this connecting recess portion 214 and the like to support the connection of the support body 20 and the handle portion 2. It is also possible to provide a fixed head configuration in which the support body 20 is fixed to the handle portion 2 so that the shaver head 1 cannot be tilted with respect to the handle portion 2, but in the present embodiment, a swing head configuration is provided in which the shaver head 1 can be tilted with respect to the handle portion 2. Specifically, as shown in Figure 11A , Figure 11B a pair of bearing portions 215 are disposed on the left and right sides of the connecting recess portion 214. Figure 6 , Figure 7 As shown in the drawing, the shaft portion 51 mounted to the front end of the handle portion 2 described later is inserted into the bearing portions 215, and the shaver head 1 can be tilted with respect to the handle portion 2 about the shaft centered on the shaft portion 51. The upper end wall 214a of the connecting recess portion 214 protrudes from the bottom surface of the recess portion 212, and is provided in a shape corresponding to the shape of the front end of the handle portion 2.

[0077] On the left and right sides of the connecting recess portion 214, a pair of cylindrical internal screw portions 216 are provided on the upper side of the bearing portions 215. In addition, seat portions 217 of the magnets 23 are formed on the left and right sides across the pair of internal screw portions 216. The seat portions 217 are provided in a shape in which the surrounding portions are recessed more than the bottom surface of the recess portion 212, and protrude more than the surroundings. Further, through-holes 218 that penetrate the front and back surfaces of the back panel 21 are formed between each of the internal screw portions 216 on the left and right sides and each of the seat portions 217.

[0078] On the other hand, the back side of the back panel 21 that constitutes the back surface of the head is provided in a shape in which the outer edge is rounded in an elliptical shape in the Z-axis direction that is the thickness direction of the shaver head 1.

[0079] The housing 22 is a member that is connected to the back panel 21 to constitute the outer shape of the support body 20 together with the back panel 21, and is provided as a member different from the back panel 21 in order to accommodate the magnets 23, the front end portion 50 of the handle portion 2 described later, and the like inside the support body 20.

[0080] As shown in the drawing, Figure 12AAs shown, the surface side of the housing 22 is provided as a placement surface 220 on which the blade unit 10 is placed. The outer shape of the housing 22 as viewed from the surface side is also substantially elliptical. The dimensions of the major axis and the minor axis of the elliptical shape are set to the dimensions corresponding to the recess 212 of the back panel 21. At the central position of the upper side in the housing 22, a portion of the wall surface of the outer edge of the housing 22 is cut away to form a groove portion 221. The groove portion 221 is provided at a position and a shape corresponding to the groove portion 213 formed in the back panel 21, and is provided so as to be fitted to the groove portion 213 as shown in Figure 5 As shown, the dimensions of the first grip portion 133 and the second grip portion 31a protruding from the groove portion 213 when the shaver head 1 is viewed from the back side.

[0081] In addition, at the central position of the lower side in the housing 22, a rectangular connecting recess 222 in which the front end portion 50 of the handle 2 is disposed is also formed by cutting away a portion of the wall surface of the outer edge of the housing 22. As shown in Figure 12B As shown, on the back side of the housing 22, a pair of bearing portions 223 is disposed on both sides of the connecting recess 222 at positions corresponding to the bearing portions 215 of the back panel 21. The shaft portion 51 of the front end portion 50 of the handle 2 is also fitted into the bearing portions 223, realizing the swing head configuration described above.

[0082] At a position above the connecting recess 222 on the back side of the housing 22, a recess 224 recessed from the back side of the housing 22 toward the surface side is formed. The recess 224 is provided in a shape corresponding to the upper end wall 214a and the internal thread portion 216 of the connecting recess 214 in the back panel 21, and a pair of through holes 224a is formed at positions corresponding to the internal thread portion 216. Further, the through holes 224a reach the placement surface 220, and as shown in Figure 12A As shown, a counterbore 225 is formed around the through holes 224a in the placement surface 220. Further, as shown in Figure 12B As shown, a cylindrical spring mounting portion 226 is formed on the upper side of the connecting recess 222 in the bottom surface of the recess 224, and the spring 25 is fitted into the spring mounting portion 226.

[0083] In addition, a pair of receiving portions 227 that receive the magnet 23 and the magnet holder 24 is formed on both sides of the pair of through holes 224a in the housing 22. By disposing the magnet 23 and the like in the receiving portions 227, the blade unit 10 and the cover unit 30 are magnetically attracted to the support body 20.

[0084] Each of the accommodation portions 227 is recessed in a substantially rectangular parallelepiped shape. The wall thickness of the housing 22 varies at a position where each of the accommodation portions 227 is formed. Specifically, when viewed in the Z-axis direction, a portion 22a of each of the accommodation portions 227 that is located on the inner side of the housing 22 and overlaps the placement surface 220 has a thicker wall thickness of the housing 22 than a portion 22b that is located on the outer side of the placement surface 220. In the case of the present embodiment, the portion 22a retains the material of the housing 22, and the portion 22b is in a state where the material of the housing 22 is not present, but the material can be retained at the portion 22b.

[0085] One surface of the portion 22a on the surface side constitutes a part of the placement surface 220 and becomes a position where the blade unit 10, specifically the frame 13, is magnetically attracted or repelled. The portion 22b becomes a position where the cover unit 30 is magnetically attracted. The wall thickness of the housing 22 is thicker at the portion 22a than at the portion 22b. Thus, the distance between the portion of the blade unit 10 that is magnetically attracted or repelled by the magnet 23 and the magnet 23 is longer than the distance between the portion of the cover unit 30 that is magnetically attracted by the magnet 23 and the magnet 23. Therefore, the magnetic attraction force between the magnet 23 and the cover unit 30 is stronger than the magnetic attraction force between the magnet 23 and the blade unit 10.

[0086] Further, between each of the through holes 224a on the left and right sides and each of the accommodation portions 227, a through hole 228 that penetrates the front and back surfaces of the housing 22 is formed. The through hole 228 is provided in a position and a shape that correspond to the through hole 218 formed in the back panel 21 and is connected to the through hole 218 to communicate the inside and the outside of the shaver head 1. Thus, when the shaver head 1 is washed with water, dirt and water on the inside of the shaver head 1 are discharged through the through holes 218, 228.

[0087] In addition, on the surface side of the housing 22, at positions on the four corners of the placement surface 220 and on the outer side of the X-axis direction than the accommodation portions 227, holding pieces 229 that protrude from the placement surface 220 are formed. In the holding pieces 229, an inner wall surface 229a that is in contact with the placement surface 220 is a curved surface in a circular arc shape and can position the frame 13.

[0088] The magnet 23 is composed of a permanent magnet, as shown in FIG. 2, for example. Figure 6 , Figure 7 The magnet 23 is in a rectangular parallelepiped shape and is provided in a size that corresponds to the accommodation portion 227. The material of the magnet 23 is arbitrary, and the magnet 23 can also be made of metal if an alloy magnet or the like is used. In this case, the magnet 23 is also made of metal.

[0089] The magnet holder 24 is provided as needed and is arranged so as to surround the periphery of the magnet 23, as shown in FIG. 2, for example. When viewed in the X-axis direction, the magnet holder 24 is in a U shape. By accommodating the magnet 23 in the accommodation portion 227 in a state where the magnet 23 is surrounded by the magnet holder 24, the movement of the magnet 23 with respect to the housing 22 is suppressed. Figure 6 , Figure 7 The magnet holder 24 is provided as needed and is arranged so as to surround the periphery of the magnet 23, as shown in FIG. 2, for example. When viewed in the X-axis direction, the magnet holder 24 is in a U shape. By accommodating the magnet 23 in the accommodation portion 227 in a state where the magnet 23 is surrounded by the magnet holder 24, the movement of the magnet 23 with respect to the housing 22 is suppressed.

[0090] Spring 25 is a compression coil spring and is installed in spring mounting portion 226. Spring 25 is disposed between the bottom surface of recess 224 in housing 22 and the front end portion 50 of handle 2, and applies force to the front end portion 50 of handle 2 through compression reaction force. Thus, when viewed from the right side of razor S, force is applied to handle 2 in a clockwise direction centered on shaft portion 51 relative to razor head 1. The initial position is the position where the bottom 50c of connecting recess 222 in front end portion 50 of handle 2, which is disposed in housing 22 and described later, abuts against the bottom surface of connecting recess 222. When no load is applied to razor head 1, handle 2 is in the initial position due to compression reaction force of spring 25. Moreover, when shaving, load is applied to razor head 1, and when viewed from the right side of razor S, a torque is applied to razor head 1 in a clockwise direction centered on shaft portion 51, razor head 1 swings against compression reaction force of spring 25.

[0091] The screw 26 serves to integrate the housing 22 with the back panel 21. By fastening the screw 26 through the through hole 224a and the internal thread 216, the housing 22 is fixed to the back panel 21. Since a countersunk hole 225 is formed around the through hole 224a in the mounting surface 220, the head of the screw 26 enters the countersunk hole 225, preventing the screw 26 from protruding.

[0092] [Structure of cover 30]

[0093] like Figure 1 As shown, the cover 30 is a component that exposes the tip 11a of the blade body 11 at its central position while covering the outer edge of the blade body 10. The razor head 1 is formed by mounting the cover 30 to the support body 20 such that it surrounds the outer edge of the blade body 10 and the outer edge of the outer casing 22. Furthermore, the cover 30 is one of the components constituting the blade of the razor S, is made of metal, and has a mirror-like surface on its exposed exterior.

[0094] like Figure 2 As shown, the shape of the cover portion 30, viewed from the surface side, is approximately elliptical. The wall surface constituting the surface of the cover portion 30 is designated as the cover surface 30a, and the surface of this cover surface 30a constitutes the head surface. The cover portion 30 is as follows... Figure 13A The diagram shows an outer peripheral wall 31 along the outer edge of an elliptical shape, as shown. Figure 13BA recess 32 recessed in an elliptical shape from the back surface side toward the surface side is formed on the inner side of the outer peripheral wall 31. The bottom surface of the recess 32 is constituted by the back surface of the cover surface 30a, and the inner wall surface of the recess 32 is constituted by the outer peripheral wall 31. The blade body portion 10, a portion of the housing 22, and the like are arranged in this recess 32. The shape inside the recess 32 corresponds to the shape of the blade body portion 10 and the housing 22. Therefore, the cover portion 30 can be mounted to the support body 20 without shaking. In addition, when the cover portion 30 is mounted to the support body 20, the blade body portion 10 is sandwiched by the back surface of the cover surface 30a in the cover portion 30 and the support body 20. Also, when the cover portion 30 is mounted to the support body 20, a portion of the bottom surface of the recess 32 abuts against both ends of the blade body 11, and thus a load that presses the blade body portion 10 toward the housing 22 side is applied. Therefore, when the cover portion 30 is mounted to the support body 20, shaking of the blade body portion 10 is also suppressed by the elastic force of the plate spring portion 124 and the deflection of each portion of the blade body portion 10.

[0095] In addition, seat portions 32a are provided at both ends in the Y-axis direction inside the recess 32. The seat portions 32a are fixed to the cover portion 30 Figure 6 、 Figure 7 The fitting 33 shown in the drawing is provided. The fitting 33 is a portion that is magnetically attracted to the magnet 23. When the cover portion 30 is mounted to the support body 20, the fitting 33 is magnetically attracted to the magnet 23 at the portion 22b in the housing 22. In the case where the cover portion 30 is made of a magnetic metal, the seat portions 32a can be directly magnetically attracted to the magnet 23 even without the fitting 33. However, if the fitting 33 is mounted, the seat portions 32a are magnetically attracted to the magnet 23 via the fitting 33, and thus the cover portion 30 can not be a magnetic metal.

[0096] The seat portions 32a are constituted by partially protruding the bottom surface of the recess 32 so as to cover each seat portion 32a, and one fitting 33 is arranged in each seat portion 32a. Each fitting 33 is a member whose cross section taken along the YZ plane is V-shaped, and is structured to have an inner wall surface 33a along the XZ plane and an attraction surface 33b arranged at the front end of the seat portion 32a along the XY plane. Also, when the cover portion 30 is mounted to the support body 20, the cover portion 30 is integrated with the support body 20 by the attraction surface 33b being magnetically attracted to the magnet 23. In the Y-axis direction, the interval between the two fittings 33 coincides with the size of the placement surface 220 and the frame 13, and the placement surface 220 and the blade body portion 10 are arranged between the two fittings 33 when the cover portion 30 is mounted to the support body 20.

[0097] The surface side in the cover portion 30 is a portion that becomes the skin contact surface 34. This skin contact surface 34 comes into contact with the user's skin at the time of shaving with the shaver S. A substantially rectangular window portion 35 that penetrates from the surface side to the back side of the cover portion 30 and has the Y-axis direction as the length direction is formed in the skin contact surface 34. By this window portion 35, the blade body 11 is exposed from the cover portion 30. Further, on both sides in the up-and-down direction of the skin contact surface 34 across the window portion 35, a recessed portion 34a that recesses the skin contact surface 34 is formed. The both sides in the left-and-right direction of the skin contact surface 34 across the window portion 35 and the recessed portion 34a are flat surfaces 34b that are semicircular. By forming the recessed portion 34a, the blade tip 11a of the blade body 11 protrudes from the bottom surface of the recessed portion 34a to the surface side, and deep shaving can be performed. Further, both ends of the blade body 11 are covered by the flat surfaces 34b, and the both ends of the blade body 11 are inhibited from catching to the user's skin at the time of shaving.

[0098] Further, the bottom surface of the recessed portion 34a of the skin contact surface 34, the upper side surface 34c that is on the upper side of the window portion 35, that is, on the back side in the shaving direction is provided as a flat surface. Further, the lower side surface 34d that is on the lower side of the window portion 35, that is, on the front side in the shaving direction is provided as a configuration in which a plurality of slits 34e that extend in the X-axis direction are aligned in the Y-axis direction. Therefore, with the lower side surface 34d, the contact area with the skin is reduced in correspondence with the formation of the slits 34e, and the adhesion to the skin is inhibited, and by the entry of the shaving cream and moisture into the slits 34e, smoother shaving can be achieved. Further, with the upper side surface 34c, smoother skin feel can be achieved by being provided as a flat surface.

[0099] As described above, the shape of the cover portion 30 as viewed from the surface side is a substantially elliptical shape, but is a shape in which the outer edge of the elliptical shape in the Z-axis direction that is the thickness direction of the shaver head 1 is rounded. In more detail, at a position of the cover portion 30 that is on the outer side of the flat surface 34b, that is, on the outer side of the recessed portion 34a, the outer edge of the cover portion 30 is rounded in the thickness direction.

[0100] Further, as shown in Figs. 1 and 2, the outer peripheral wall 31 of the cover portion 30 is provided with a first grip portion 31b that protrudes toward the back side. The first grip portion 31b is a portion that is formed in a position of the outer peripheral wall 31 that is on the outer side of the flat surface 34b, that is, on the outer side of the recessed portion 34a. The first grip portion 31b is a portion that protrudes from the outer peripheral wall 31 toward the back side. The first grip portion 31b is a portion that is formed in a position of the outer peripheral wall 31 that is on the outer side of the flat surface 34b, that is, on the outer side of the recessed portion 34a. The first grip portion 31b is a portion that protrudes from the outer peripheral wall 31 toward the back side. Figure 13A Figure 13B Further, as shown in Figs. 1 and 2, the outer peripheral wall 31 of the cover portion 30 is provided with a first grip portion 31b that protrudes toward the back side. The first grip portion 31b is a portion that is formed in a position of the outer peripheral wall 31 that is on the outer side of the flat surface 34b, that is, on the outer side of the recessed portion 34a. The first grip portion 31b is a portion that protrudes from the outer peripheral wall 31 toward the back side. Figure 13B Further, as shown in Figs. 1 and 2, the outer peripheral wall 31 of the cover portion 30 is provided with a first grip portion 31b that protrudes toward the back side. The first grip portion 31b is a portion that is formed in a position of the outer peripheral wall 31 that is on the outer side of the flat surface 34b, that is, on the outer side of the recessed portion 34a. The first grip portion 31b is a portion that protrudes from the outer peripheral wall 31 toward the back side.

[0101] ​Further, a semicircular connecting recess 31b is formed by cutting a portion of the outer peripheral wall 31 at a central position on the lower side in the cover portion 30. The front end portion 50 of the handle portion 2 is disposed at this connecting recess 31b together with other connecting recesses 214, 222, and the like, and the connection of the support body 20 and the handle portion 2 is performed.

[0102] [Structure of handle portion 2]

[0103] The handle portion 2 is a portion that is held by a user when the razor S is used. The handle portion 2 is one of the portions that constitute the body of the razor S, is made of metal, and the surface that is exposed to the outside is a mirror surface. Specifically, the handle portion 2 is a rod-shaped member whose one direction is the length direction, and has a grip portion 40, a front end portion 50 on the upper end side of the grip portion 40, and a rear end portion 60 on the lower end side of the grip portion 40.

[0104] The grip portion 40 is a portion that is located between the front end portion 50 and the rear end portion 60, and has a cross-sectional shape that is circular in a direction that is normal to the length direction of the handle portion 2. The central axis in the length direction of the grip portion 40 is inclined at a prescribed angle with respect to the back surface of the razor head 1 that is parallel to the XY plane, and the angle changes according to the amount of oscillation when the razor head 1 is oscillated. The grip portion 40 can have any shape, and in addition to a straight rod-shaped member, can be provided in a shape in which the middle portion in the length direction is bulged more than other portions, or a curved shape, or a shape in which a recess or an opening is formed at the middle portion in the length direction. However, if the grip portion 40 is constituted by a straight rod-shaped member whose cross-sectional shape in a direction that is normal to one direction is circular, elliptical, or a shape in which each corner of a polygon is rounded, a more simple and sharp design can be achieved, and a shape that is easy to hold when used can be achieved.

[0105] The grip portion 40 has a tapered shape in which the cross-sectional area gradually decreases from the rear end portion 60 toward the front end portion 50. Therefore, a shape in which the grip portion 40 is thin on the side of the connecting portion to the razor head 1 and thick on the side of the rear end portion 60 can be achieved. Therefore, a simple design can be achieved, and a shape that is easy to hold when used can be achieved. Further, since the center of gravity of the handle portion 2 can be made on the side of the rear end portion 60, the center of gravity position of the entire razor S can be moved from the front end portion 50 where the razor head 1 is attached to the side of the rear end portion 60, and stable shaving can be achieved.

[0106] Further, the grip portion 40 is a solid metal in which the inside is filled. Therefore, the weight of the razor S can be made large, the razor S can have a more weighty and heavy feeling, and the rigidity of the product can be improved. Further, stable shaving can be achieved when a user uses the razor S compared to the case where the weight is small, and a load is easily applied when shaving, and therefore, a deep shave can be further achieved.

[0107] The front end portion 50 is a portion located on one side in the length direction of the handle portion 2 and connected to the support body 20 in the shaving head 1. As shown in Figures 3-5 the outer wall surface 50a in the front end portion 50 on the side of the grip portion 40 is continuous to the outer wall surface 401 of the grip portion 40 without a joint. Also, at the portion of the front end portion 50 connected to the support body 20, the outer wall surface 50a is a curved surface gradually increasing in radial dimension from the center axis of the handle portion 2 in the length direction of the grip portion 40 as it approaches the connection position to the support body 20. Also, at each portion where the outer wall surface 50a is connected to the back surface and the lower surface of the support body 20, it is formed in a shape without a joint. Thus, the connection portion in the handle portion 2 to the shaving head 1 can be formed in a rounded shape. Further, by providing the connection portion in a curved surface, which is a portion where dirt is likely to accumulate, it is possible to suppress the accumulation of dirt and to form a shape that is easier to keep clean.

[0108] As shown in Figure 14A , Figure 14B the portion of the front end portion 50 disposed inside the support body 20 is formed in a structure having a back portion 50b and a bottom portion 50c. The back portion 50b is semicircular corresponding to the connection recess 214 of the back surface plate 21. The bottom portion 50c is a quadrangular shape corresponding to the connection recess 222 of the housing 22 and the connection recess 31b of the cover portion 30. The bottom portion 50c is disposed protruding from one face 50d of the back portion 50b on the side of the housing 22, and when the front end portion 50 is connected to the support body 20, the back portion 50b is fitted into the connection recess 214 and the bottom portion 50c is fitted into the connection recesses 222 and 31b.

[0109] A through-hole 50e of a cylindrical shape extending in the Y-axis direction is formed in the front end portion 50. The housing 22 and the back surface plate 21 are assembled such that the shaft portion 51 is inserted through the through-hole 50e and supported by the bearing portion 215 of the back surface plate 21 and the bearing portion 223 of the housing 22, whereby the front end portion 50 is connected to the support body 20.

[0110] Further, a spring hole 50f into which one end of the spring 25 is inserted is formed in one face 50d of the back portion 50b. When the front end portion 50 is connected to the support body 20, one end of the spring 25 installed to the spring mounting portion 226 of the housing 22 is inserted into the spring hole 50f. By the compression reaction force of this spring 25, a force is applied in the direction in which the back portion 50b is away from the housing 22, that is, in the direction in which the shaving head 1 is returned to the initial position.

[0111] The rear end portion 60 is a portion located on the other side in the length direction of the handle portion 2. The rear end portion 60 is a spherical surface gradually decreasing in cross-sectional area as it is away from the front end portion 50. Thus, the rear end portion 60 also has a rounded shape.

[0112] By the above configuration, the shaving razor S is constituted. As shown in Figure 1As shown, the shaving razor S thus configured is used in a state where the blade unit 10 and the support body 20 are covered by the cover 30. Also, at the time of replacement of the blade unit 10, first, the user detaches the cover 30 from the support body 20 by gripping the second grip portion 31a with fingers, and exposes the blade unit 10 to the outer edge portion, and next, detaches the blade unit 10 by gripping the first grip portion 133. Thereby, the blade unit 10 can be easily and safely detached from the support body 20. Next, in a state where only the support body 20 and the handle 2 are present, the blade unit 10 is placed on the placement surface 220 of the support body 20, and then the cover 30 is attached to the support body 20. Thereby, the replacement of the blade unit 10 is completed. At this time, at the time of contact of the blade unit 10 with the placement surface 220, the frame 13 is magnetically adsorbed or attracted to the placement surface 220 based on the magnetic force of the magnet 23, and the positioning of the blade unit 10 is performed by the holding piece 229. Also, at the time of attachment of the cover 30 to the support body 20, the fitting 33 is magnetically adsorbed to the magnet holder 24 based on the magnetic force of the magnet 23. Further, the inner wall surface of the outer peripheral wall 31 abuts against the outer edge of the placement surface 220, in other words, the outer edge of the housing 22, and thereby the cover 30 is attached to the support body 20 without shaking. At the time of attachment of the cover 30 to the support body 20, the blade tip 11a of the blade 11 in the blade unit 10 is forced to the inner surface side of the cover 30 by the force of the leaf spring portion 124, and thereby the shaking can be suppressed. Figure 10 In a state where only the support body 20 and the handle 2 are present, the blade unit 10 is placed on the placement surface 220 of the support body 20, and then the cover 30 is attached to the support body 20. Thereby, the replacement of the blade unit 10 is completed. At this time, at the time of contact of the blade unit 10 with the placement surface 220, the frame 13 is magnetically adsorbed or attracted to the placement surface 220 based on the magnetic force of the magnet 23, and the positioning of the blade unit 10 is performed by the holding piece 229. Also, at the time of attachment of the cover 30 to the support body 20, the fitting 33 is magnetically adsorbed to the magnet holder 24 based on the magnetic force of the magnet 23. Further, the inner wall surface of the outer peripheral wall 31 abuts against the outer edge of the placement surface 220, in other words, the outer edge of the housing 22, and thereby the cover 30 is attached to the support body 20 without shaking. At the time of attachment of the cover 30 to the support body 20, the blade tip 11a of the blade 11 in the blade unit 10 is forced to the inner surface side of the cover 30 by the force of the leaf spring portion 124, and thereby the shaking can be suppressed.

[0113] At the time of attachment of the blade unit 10 to the support body 20, the frame 13 can be directly magnetically adsorbed to the placement surface 220, but in this case, as shown, Figure 15 the leaf spring portion 124 is brought into contact with the placement surface 220, and the frame 13 is separated from the placement surface 220. At the time of use of the shaving razor S, the blade unit 10 is flexed in the Z-axis direction by the elasticity of the leaf spring portion 124, and thereby in the case where a strong force is applied to the blade 11 in contact with the skin, the blade unit 10 is displaced to the inner side of the razor head 1, and the contact of the blade 11 with respect to the skin is moderated. It is preferable that the frame 13 is separated from the placement surface 220 so that the leaf spring portion 124 can be displaced at the time of such action. However, in the case where such a configuration is provided, the frame 13 is not directly magnetically adsorbed to the placement surface 220, but is magnetically attracted at a position separated from the placement surface 220. In this case, the magnetic attraction force in the latter case can be smaller than the magnetic adsorption force in the former case, but since the blade unit 10 can obtain the magnetic attraction force to the extent that it does not fall off from the support body 20, the blade unit 10 can be attached to the support body 20 without problems. Also, although the blade unit 10 becomes less likely to be displaced to the inner side of the razor head 1 in the case where a strong force is applied to the blade 11, it is also possible to provide a configuration where the frame 13 is directly magnetically adsorbed to the placement surface 220.

[0114] Further, even in a state where the frame 13 is away from the placement surface 220, since it becomes a state where the plate spring portion 124 is in contact with the placement surface 220, in this case as well, the blade body portion 10 is expressed as being magnetically attracted to the placement surface 220 in the present specification.

[0115] [Effects of the razor S]

[0116] Next, the effects of the razor S thus configured will be described.

[0117] (1) In the razor S of the present embodiment, the blade body portion 10 provided with the blade body 11 is placed on the placement surface 220 of the support body 20 by magnetic attraction, and the cover portion 30 is also magnetically attracted and mounted to the support body 20. Further, while the blade body portion 10 is sandwiched by the cover portion 30 and the support body 20, the blade body portion 10 can be replaced when the cover portion 30 is detached from the support body 20.

[0118] Thus, since the blade body portion 10 is magnetically attracted to the support body 20, when the cover portion 30 is detached, the blade body portion 10 is also magnetically attracted to the support body 20 at the same time, and the blade body portion 10 can be easily detached from the support body 20 against the magnetic attraction force when the blade body portion 10 is detached. In addition, by simply bringing the support body 20 close to a new blade body portion 10, the blade body portion 10 is magnetically attracted to the support body 20, and the replacement of the blade body portion 10 can be easily performed. Thus, only the blade body portion 10 can be replaced. Further, if only the blade body portion 10 is replaced, the replacement parts can be limited to the minimum. Furthermore, by magnetically attracting the cover portion 30 to the support body 20, the blade body portion 10 can be sandwiched by the cover portion 30 and the support body 20, and stable shaving can be achieved.

[0119] In addition, the number of times of touching the blade body portion 10 and the blade tip 11a can be reduced, and the installation and detachment of the blade body portion 10 can be performed without touching the blade body portion 10, so that the user can easily perform the replacement of the blade body portion 10, and the user can reduce the risk of being injured by touching the blade tip 11a or the psychological uneasiness of being injured by touching the blade body portion 10.

[0120] Further, since only the blade body portion 10 can be replaced, it is possible to replace only the minimum necessary, and the amount of waste is reduced, and it is in line with the target 12.5 of the target 12 of the SDGs, "Responsible Production and Consumption", "Substantially reduce the generation of waste by 2030 through the prevention of generation, reduction, recycling, and reuse of waste."

[0121] (2) The magnet 23 is arranged to magnetically attract the cover portion 30 and the blade body portion 10 to the support body 20, and the magnetic attraction force between the magnet 23 and the cover portion 30 is stronger than the magnetic attraction force between the magnet 23 and the blade body portion 10. Thus, the cover portion 30 is integrated with the support body 20 by the stronger magnetic attraction force, and the cover portion 30 is prevented from being separated from the support body 20 during shaving. In addition, the blade body portion 10 is integrated with the support body 20 by the weaker magnetic attraction force, and the blade body portion 10 is easily detached from the support body 20 during replacement.

[0122] In use, the blade body portion 10 is sandwiched between the cover portion 30 and the support body 20, and the blade body portion 10 is not separated from the support body 20 if the cover portion 30 is not separated from the support body 20. Since the cover portion 30 is magnetically attracted to the support body 20 by the stronger magnetic attraction force and the blade body portion 10 is not easily separated from the support body 20, the safety razor S can be used safely. On the other hand, after the cover portion 30 is detached, the blade body portion 10 is magnetically attracted to the support body 20 by the weaker magnetic attraction force and is easily detached, and the user can easily detach the blade body portion 10.

[0123] In the present embodiment, the strength of the magnetic attraction force is set by making the distance between the portion of the blade body portion 10 that is magnetically attracted or magnetically attracted to the magnet 23 and the magnet 23 longer than the distance between the portion of the cover portion 30 that is magnetically attracted to the magnet 23 and the magnet 23. Thus, the strength of the magnetic attraction force can be made by simply making the distance between the magnet 23 and the cover portion 30 different from the distance between the magnet 23 and the blade body portion 10, and thus the shaving head 1 can be made simple.

[0124] (3) The cover portion 30 is provided with a cover surface 30a that sandwiches the blade body portion 10 with the support body 20 and an outer peripheral wall 31 that is arranged at the outer edge of the cover surface 30a. Furthermore, the outer peripheral wall 31 surrounds the outer edge of the blade body portion 10 and the inner wall surface of the outer peripheral wall 31 abuts against the outer edge of the housing 22.

[0125] Thus, the blade body portion 10 is positioned and held by the cover surface 30a and the support body 20 sandwiching the blade body portion 10 and by the outer peripheral wall 31 surrounding the outer edge of the blade body portion 10. In addition, the cover portion 30 is positioned and held with respect to the support body 20 by the outer peripheral wall 31 of the cover portion 30 abutting against the outer edge of the housing 22. Thus, the blade body portion 10 and the cover portion 30 are prevented from wobbling, and more stable shaving can be achieved.

[0126] (4) The blade body portion 10 is provided with a frame 13 that supports the blade body 11 in such a manner that the frame 13 is arranged between the blade body 11 and the support body 20 and the magnet 23 magnetically attracts or magnetically attracts the frame 13. In addition, a first gripping portion 133 that protrudes from the support body 20 is provided on the frame 13 at a portion of the shaving head 1 that is opposite to the portion at which the support body 20 is connected to the handle portion 2.

[0127] Therefore, the razor body 10 can be magnetically attached to the support body 20 by magnetically attracting or repelling the magnet 23 to the frame 13. Also, since the first gripping portion 133 is provided in the frame 13, the user can easily detach the razor body 10 from the support body 20 by gripping the first gripping portion 133. In addition, since the first gripping portion 133 is disposed on the opposite side of the portion where the support body 20 is connected to the handle 2 in the shaving head 1, the first gripping portion 133 can be disposed in the direction opposite to the direction in which the blade tip 11a of the blade body 11 faces. Therefore, when the razor body 10 is detached from the support body 20, the user touches the blade body 11 in the direction opposite to the cutting direction, and thus the user can be protected from being injured. Also, the user can easily replace the razor body 10, since the situation of being injured or the anxiety about being injured by touching the razor body 10 can be reduced.

[0128] In addition, since the first gripping portion 133 is provided, the shape of the razor body 10 in the direction in which the plurality of blade bodies 11 are arranged, that is, in the up-down direction, is asymmetric, and thus the orientation of the razor body 10 when the razor body 10 is attached to the support body 20 can be easily determined.

[0129] (5) A second gripping portion 31a that protrudes from the support body 20 and covers the first gripping portion 133 is provided on the outer peripheral wall 31 of the cover portion 30 on the opposite side of the portion where the support body 20 is connected to the handle 2 in the shaving head 1.

[0130] In this way, by providing the second gripping portion 31a so as to cover the first gripping portion 133, the second gripping portion 31a can be gripped separately from the first gripping portion 133, and the detachment of the cover portion 30 and the detachment of the razor body 10 can be separately performed. In addition, if the second gripping portion 31a is disposed on the opposite side of the portion where the support body 20 is connected to the handle 2 in the shaving head 1, the second gripping portion 31a can be disposed in the direction opposite to the direction in which the blade tip 11a of the blade body 11 faces. Therefore, when the cover portion 30 is detached from the support body 20, the user touches the blade body 11 in the direction opposite to the cutting direction, and thus the user can be protected from being injured.

[0131] In addition, by providing the second gripping portion 31a, the shape of the cover portion 30 in the up-down direction is asymmetric, and thus the orientation of the cover portion 30 when the cover portion 30 is attached can be easily determined.

[0132] (6) The entire portion of the shaver S that is exposed to the outside is made of metal. By making the entire shaver S of metal, the shaver S can have a heavy feel. In addition, in the shaver S in which the shaver body 11 is exposed from the cover portion 30, the shaver S can have a uniform structure, and can be simple and attractive in design, and can be a product that has a high-class feel. Furthermore, since the shaver S is made of metal, the shaver S can be disposed of easily while taking into account the environment.

[0133] In addition, for example, the shaver body portion 10 is replaced when the shaver body 11 is dull, but the other portions (the handle portion 2, the cover portion 30, and the support body 20) are not replaced and are used for a long time, and thus it is desirable to suppress waste. Therefore, in addition to improving the durability of each component by metal, the shaver S can be a product that is attractive and has a high-class feel, and thus the user can use the shaver S for a long time, and this contributes to the suppression of waste.

[0134] Furthermore, the shaver head 1 and the handle portion 2 are made of metal to achieve a full-metal shaver body, but the type of metal is arbitrary. However, the fitting 33 of the cover portion 30 and the frame 13 in the shaver body portion 10, that is, the portion that is magnetically attracted or magnetically adsorbed by the magnet 23, is made of a magnetic metal.

[0135] (7) The surface of the shaver S that is exposed to the outside, that is, the support body 20, the cover portion 30, and the handle portion 2, is a mirror surface. In this way, by making the surface that is exposed to the outside a mirror surface, the shaver S can have a sharp and glossy appearance of the metal surface, and can be a structure that is easy to clean and easy to maintain cleanliness. In addition, the shaver S can have a smooth and comfortable touch, and can provide a smooth and comfortable touch to the portion of the mirror surface of the cover portion 30 that comes into contact with the skin while shaving with the shaver body 11.

[0136] (8) The handle portion 2 has a circular, elliptical, or polygonal shape in which the corners are rounded in a cross-sectional shape that has a length direction as a normal direction. By providing the handle portion 2 with such a shape, a more simple design can be achieved, and a shape that is easy to hold during use can be achieved.

[0137] Furthermore, the handle portion 2 is tapered so that the cross-sectional area gradually decreases from the rear end portion 60 side that is opposite the front end portion 50 side toward the front end portion 50 side. In this way, by making the handle portion 2 tapered, a shape can be achieved in which the joint portion with the shaver head 1 is thin, and the rear end portion 60 is thick, and the root portion is thick. Therefore, the handle portion 2 can be made to have a simple design, and can be a shape that is easy to hold during use. In addition, the center of gravity of the handle portion 2 can be made to be on the rear end portion 60 side, and thus the center of gravity of the entire shaver S can be moved from the front end portion 50 where the shaver head 1 is attached to the rear end portion 60 side, and more stable shaving can be achieved.

[0138] (9) The handle 2 is composed of a solid metal filled from the inside. Thus, the shaver S can have a more heavy and thick feeling of weight, and the rigidity of the product can be improved. In addition, stable shaving can be achieved compared to a lighter shaver, and a load is easily applied when the user uses it, so that a deep shave can be further achieved.

[0139] (10) For the shaver head 1, the shape viewed from the Z-axis direction is an elliptical shape, and the outer edge of the elliptical shape is rounded in the thickness direction on both the head surface and the head back surface. In addition, for the handle 2, the cross-sectional shape with the length direction as the normal direction is a circular shape, an elliptical shape, or a shape in which each corner of a polygonal shape is rounded.

[0140] By being configured in such a manner, the shaver S can be a rounded shape. Thus, the shaver S can be a simple and beautiful design, and although it is a cutter, it can also be a shape that brings a sense of security. In addition, there is no rough feeling of unevenness, and the shaver S can be a shape that is comfortable to the touch. Furthermore, by being a rounded shape, dirt is less likely to accumulate, and the shaver S can be a shape that is easy to keep clean.

[0141] In addition, in the portion of the front end portion 50 of the handle 2 that is connected to the support body 20, the outer wall surface 50a of the front end portion 50 is a curved surface that gradually increases in radial dimension from the center axis of the handle 2 as it approaches the connection position to the support body 20.

[0142] In this way, by configuring not only the shaver head 1 and the handle 2 as curved surfaces but also the portions where they are connected as curved surfaces, a more rounded shape can be achieved. Furthermore, by configuring a position such as the connection portion, where dirt is likely to accumulate, as a curved surface, dirt is less likely to accumulate, and the shaver S can be a shape that is even easier to keep clean.

[0143] (Second Embodiment)

[0144] The second embodiment will be described. The present embodiment is an embodiment in which the shaver S is provided with a stand for storage and is a shaver with a stand, with respect to the first embodiment, and is the same as the first embodiment except for this, so only the portions that differ from the first embodiment will be described.

[0145] As shown in Figs. 5 and 6, the stand 500 is a bottomed cylindrical shape having a side surface 501 and a bottom surface 502, and the shaver S is stored by inserting the handle 2 into the hollow portion 503 formed by the side surface 501 and the bottom surface 502 from the rear end portion 60 side. Specifically, the stand 500 is a circular truncated cone shape, and the upper surface side of the circular truncated cone shape is open to form the hollow portion 503. Figure 16A Figure 16B As shown in Figs. 5 and 6, the stand 500 is a bottomed cylindrical shape having a side surface 501 and a bottom surface 502, and the shaver S is stored by inserting the handle 2 into the hollow portion 503 formed by the side surface 501 and the bottom surface 502 from the rear end portion 60 side. Specifically, the stand 500 is a circular truncated cone shape, and the upper surface side of the circular truncated cone shape is open to form the hollow portion 503.

[0146] ​On the surface side and the back side of the stand 500, that is, on the front side and the opposite side of the paper surface of the conical frustum-shaped stand 500 across the central axis thereof Figure 16A A slit 504 formed along the central axis direction from the upper surface of the stand 500 is provided on the front side and the opposite side of the paper surface of the stand 500. The width of the slit 504 is constant, but the upper end surface of the stand 500 on both sides of the slit 504 is rounded by gradually widening as it approaches the upper surface side. In addition, on the surface side of the stand 500, the slit 504 is formed to reach the lower surface from the upper surface, and on the lower surface side, the lower end surface of the stand 500 on both sides of the slit 504 is also rounded by gradually widening as it approaches the lower surface side. Furthermore, on the back side of the stand 500, the front end of the lower side of the slit 504 is rounded into a semicircular shape. In this way, while the slit 504 is formed, the upper end surface and the lower end surface of the stand 500 on both sides of the slit 504 are rounded, so that the designability can be improved, and at the same time, the same rounded shape as the main body of the razor S can be obtained. In addition, by providing the slit 504 along the central axis on the surface side of the stand 500, the insertion direction when the handle 2 is inserted into the hollow portion 503 can be indicated, and the entrance of the hollow portion 503 can be easily seen, so that the user can easily store the razor S in the stand 500.

[0147] In addition, on the back side of the stand 500, a part of the side surface 501 is provided as a flat surface 505 along the insertion direction of the handle 2, and a holding magnet 506 is installed on the flat surface 505. By the holding magnet 506, the stand 500 is magnetically attached to a magnetic member, so that the stand 500 can be installed on a magnetic member provided on a wall surface or the like in a washroom, for example.

[0148] On the central position of the flat surface 505, a slit 507 is formed along the central axis direction from the lower surface of the stand 500. The slit 507 gradually widens as it approaches the lower surface side of the stand 500, and the front end of the lower side on the upper side is rounded into a semicircular shape. The slit 504 on the surface side and the slit 507 on the back side of the stand 500 are connected to the hollow portion 503, so that even if the razor S is stored in the stand 500 in a wet state after use of the razor S, drainage can be performed through the slit 504 and the slit 507.

[0149] Furthermore, the surface exposed to the outside in the stand 500 of such a configuration, for example, the side surface 501 including the opening end of the hollow portion 503, and the portion in the slit 504, is a mirror surface.

[0150] As explained above, this embodiment includes a bracket 500 for storing the main body of the razor S. Therefore, the razor S can be easily stored simply by inserting it into the bracket 500. Furthermore, the bracket 500 can be installed by magnetically attaching the retaining magnet 506 to a wall or other surface made of a magnetic component, ensuring a secure storage location for the razor S. Therefore, it is not necessary to secure a storage location on a sink or similar surface. Additionally, since the bracket 500 is attached to a magnetic component by the magnetic attraction of the retaining magnet 506, it can be easily disassembled and moved. Moreover, unlike structures such as suction cups where the attraction force may gradually decrease, it can be installed long-term. Especially since the razor S is constructed with a heavy, all-metal blade, it is important to prevent the bracket 500 from falling off due to a decrease in attraction force; preventing this ensures safety and peace of mind.

[0151] Furthermore, by making the exposed surfaces of the holder 500 mirrored, the holder 500 achieves a striking and glossy appearance reminiscent of a metallic surface, and also becomes easy to clean and maintain. Additionally, it provides a pleasant tactile experience. Moreover, with the exposed surfaces of the support 20, the cover 30, and the handle 2 also mirrored, it achieves a unified look with the main body of the razor S, further enhancing its design appeal.

[0152] (Third implementation method)

[0153] The third embodiment will be described. In this embodiment, a preferred replacement razor storage container that houses the razor body 10 will be described, in contrast to the razor S described in the first and second embodiments. Furthermore, the razor S is the same as in the first and second embodiments.

[0154] like Figure 17A , Figure 17B As shown, the blade body 10 is stored in the replacement blade storage container 600. The replacement blade storage container 600 consists of a container body 610 and a cover 620.

[0155] The container body 610 has a structure having a recess 611 that forms a storage space for housing the blade part 10 and a flange 612 provided on the opening side of the recess 611. The recess 611 is set to a depth such that the blade part 10 does not protrude from the opening and that when the support 20 in the razor head 1 is brought close, the mounting surface 220 of the support 20 contacts the blade part 10. The blade part 10 is housed in the recess 611 with the blade 11 side facing the bottom surface side, which is the lower side of the recess 611, and the frame 13 side facing the opening side, which is the upper side of the recess 611. The flange 612 is planar and protrudes outward from the opening of the recess 611.

[0156] The lid portion 620 covers the cutter body portion 10 housed in the recessed portion 611 while closing the housing space of the cutter body portion 10 by being attached to the flat flange portion 612. The lid portion 620 is configured by a sheet as shown in the drawing attached to the flange portion 612, or a resin cover provided with a protrusion embedded in the recessed portion 611, and can be easily detached from the flange portion 612. In the drawing, the case where the lid portion 620 is configured by a sheet is shown.

[0157] The cutter body portion 10 housed in such a replacement cutter housing container 600 can be replaced. At the time of replacement of the cutter body portion 10, the lid portion 620 is detached from the flange portion 612, and the cutter body portion 10 is exposed in a manner that the frame 13 side can be seen from the opening entrance side of the recessed portion 611. Then, when the support body 20 is brought close to the cutter body portion 10 in this state, the frame 13 is magnetically attracted by the magnet 23, and the cutter body portion 10 is attached to the placement surface 220.

[0158] After the support body 20 to which the cutter body portion 10 is attached is attached to the cover portion 30, the cover portion 30 is magnetically attached to the support body 20 by the magnet 23. Thus, the cutter body portion 10 is clamped between the cover portion 30 and the support body 20 without shaking, and the shaving head 1 is configured, and the replacement of the cutter body portion 10 is completed.

[0159] Thus, the replacement cutter housing container 600 can be configured so that the frame 13 side of the cutter body portion 10 is housed in the recessed portion 611 of the container main body portion 610 so as to face upward. If the replacement cutter housing container 600 is configured in this manner, the cutter body portion 10 can be taken out by merely detaching the lid portion 620. In addition, the cutter body portion 10 can be attached to the support body 20 by magnetically attracting the cutter body portion 10 by the magnet 23 provided to the support body 20 in a state where the cutter body portion 10 is disposed in the recessed portion 611 of the container main body portion 610. Therefore, the user can easily and safely perform replacement of the replacement cutter without touching the replacement cutter.

[0160] Further, since only the cutter body portion 10 can be replaced, the unit price of each product of the replacement cutter can be reduced compared to the replacement cutter of the shaving head in which the cutter and the resin member are integrated, and thus the number of products per equivalent cost can be increased. Therefore, the frequency of replacement of the replacement cutter can be increased, and the shaving can be performed using a newer blade, and thus the satisfaction of the user can also be increased.

[0161] In addition, for the replacement cutter housing container 600, as shown in Figure 18 the container main body portion 610 can be integrated in a configuration in which a plurality of container main body portions 610 are arranged so as to be connected by the flange portion 612. In this case, the adjacent container main body portions 610 can be separated by providing a thin-walled fragile portion or a point line at the connected portion of the flange portion 612.

[0162] Thus, if the configuration is such that the plurality of container body portions 610 are connected at the flange portions 612 and can be disconnected at the connected portions, the replacement blades can be used one by one as in the case of disposable contact lenses. Thus, the user can carry the required number of replacement blades when traveling or on business trips. In addition, the container body portions 610 after the replacement blades are removed can also be disconnected and properly discarded.

[0163] In addition, if the configuration of the replacement blade storage container 600 is such, the replacement blade storage container 600 can be made thin, and can also be stored in the storage case 700 or the like in multiple layers, so that the storage space can be reduced even if a large number of replacement blades are stored. Figure 18

[0164] (Other Embodiments)

[0165] The present disclosure is not limited to the above-described embodiments, and can be appropriately changed within the scope of the claims. In addition, in the above-described embodiments, it is needless to say that the elements constituting the embodiments are not necessarily essential elements except for cases where it is particularly necessary and cases where it is obviously necessary in principle. In addition, in the above-described embodiments, in cases where the number, values, amounts, ranges, and the like of the elements constituting the embodiments are mentioned, it is not limited to the specific number except for cases where it is particularly necessary and cases where it is obviously limited to the specific number in principle. In addition, in the above-described embodiments, in cases where the shape, positional relationship, and the like of the elements constituting the embodiments are mentioned, it is not limited to the shape, positional relationship, and the like except for cases where it is particularly mentioned and cases where it is limited to the shape, positional relationship, and the like in principle.

[0166] For example, the grip portion 40 is provided in a tapered shape in which the cross-sectional area gradually decreases from the rear end portion 60 toward the front end portion 50, but the cross-sectional area in the longitudinal direction can be constant.

[0167] In addition, one magnet 23 is provided on each of the left and right sides in the support body 20. Furthermore, the distance between the portion of the blade body portion 10 that is magnetically attracted or magnetically attracted by the magnet 23 and the magnet 23 is different from the distance between the portion of the cover portion 30 that is attracted by the magnet 23 and the magnet 23. Thus, the magnetic attraction force of the magnet 23 and the cover portion 30 is stronger than the magnetic attraction force of the magnet 23 and the blade body portion 10. However, this is an example in which the magnetic attraction force of the magnet 23 and the cover portion 30 and the magnetic attraction force of the magnet 23 and the blade body portion 10 are different, and can also be achieved by other structures. For example, the portion of the magnet 23 that is magnetically attracted to the cover portion 30 and the portion that is magnetically attracted to the frame 13 can be constituted by different members having different magnetic attraction forces.

[0168] ​Furthermore, in the above embodiment, a magnet 23 is provided in the support body 20 and a magnetic metal is provided in the cover 30. However, for example, a magnetic metal can also be provided in the support body 20 and a magnet can be provided in the cover 30. Additionally, magnets can be provided in both the support body 20 and the cover 30, and these magnets can attract each other. In this case, if a combination is set such that, for example, the magnet on the right side of the support body 20 is the S pole and the magnet on the left side is the N pole, and the magnet on the right side of the cover 30 is the N pole and the magnet on the left side is the S pole, then if the cover 30 is to be installed in opposite orientations, the magnets will repel the cover 30, preventing it from being installed in opposite orientations.

[0169] Alternatively, the upper side 34c of the cover 30 can be made flat, and the lower side 34d can be constructed with a plurality of slots 34e arranged therein. However, the upper side 34c can also be constructed with a plurality of slots 34e arranged therein, and the lower side 34d can also be made flat.

[0170] Furthermore, the razor S can be made of an all-metal blade, but it can also be made of resin or the like. For example, the back panel 21, outer shell 22, and cover 30 of the support 20 in the razor head 1 can be made of resin, or the handle 2 can be made of resin. In this case, if transparent resin is used, the internal structure of the blade part 10 and the like can be visually identified, and the internal mechanical feel can be displayed.

[0171] Alternatively, the support 500 can be set to a frustum shape, but it can be any shape with a bottom tube, such as a cylindrical shape, a polygonal cylindrical shape, etc.
