Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in recent years, the three Rs, namely Reduce (cherish things and reduce waste), Reuse (repeatedly use things that can be used), and Recycle (reuse waste as resources), have been proposed. As described above, the blade cartridge in a conventional razor has often been formed of resin and metal, but there is a demand for replacement with a material that is easy to recycle. In addition, among the 17 goals in the SDGs (Sustainable Development Goals, adopted at the United Nations Summit), Goal 12 aims to ensure sustainable production and consumption patterns as "the responsibility to produce and the responsibility to use", and it is required to significantly reduce the generation of waste. For example, Goal 12-5 aims to significantly reduce the generation of waste by preventing, reducing, recycling, and reusing waste by 2030. Under such circumstances, in the field of razors, it is also required to reduce the generation of waste.

[0006] Many of the razors currently on the market adopt a configuration that mainly uses resin for the handle (grip part) in order to reduce costs. However, long-term continuous use of the handle is not assumed, and it was assumed that it would be replaced in about a few weeks to a few months. However, with such razors, there is a limit to reducing the generation of waste.

DETAILED DESCRIPTION OF THE INVENTION

[0041] The razor according to one embodiment of the present invention will be specifically described with reference to the drawings. However, the embodiments and examples described below are merely examples of the present invention and do not limit the technical scope of the present invention. In each drawing, the same components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0042] Figure 1 is a perspective view of the razor 1 of the present embodiment. Figure 2 is a side view of the razor 1. Figure 3 is an enlarged perspective view of the razor head 3 of the razor 1. Figure 4 is a perspective view of the state in which the lid member 6 of the razor head 3 is removed in Figure 3. Figure 5 is an exploded perspective view of the razor head 3. Figure 6 is a view of the razor head 3 disassembled and seen from the front. Figure 7 is an exploded perspective view of the razor head 3 seen from the rear side. Figure 8 is an exploded perspective view of the blade cartridge 5.

[0043] The razor 1 of the present embodiment includes a handle 2 and a razor head 3.

[0044] [Handle 2] The handle 2 is a gripping member to be gripped by a user. The handle 2 extends in a columnar shape, and a razor head 3 is provided at the upper end which is one end thereof. In the handle 2, the side where the razor head 3 is provided is referred to as the upper side, and the opposite side is referred to as the lower side.

[0045] The handle 2 is formed such that the area of a cross-section perpendicular to the extending direction thereof increases as it moves away from the razor head 3, in other words, as it goes from the upper end toward the lower side. That is, the handle 2 becomes thicker from the upper side toward the lower side, and thus has a shape that easily suppresses the user's hand from gradually slipping downward during use. Therefore, even when a non-slip configuration is not provided on the surface of the handle 2, it has a configuration that is difficult to slip. The lower end of the handle 2 is substantially hemispherical, and in this hemispherical portion, the cross-sectional area is smaller closer to the lower end.

[0046] The handle 2 is formed of a metal with a mirror finish on the surface. However, the surface of the handle 2 does not necessarily have to be a mirror finish. Also, the handle 2 does not necessarily have to be made of metal. Even when the handle 2 is not made of metal, it is possible to make the blade cartridge 5 recyclable. When the handle 2 is formed of a metal with a mirror finish, it becomes a handle 2 with a high-class feeling and a razor 1.

[0047] As shown in the exploded perspective view of the razor head pedestal 4 in FIG. 12, the handle 2 has a shaft portion 25 for supporting the razor head 3 so as to be swingable, that is, swingable, with respect to the handle 2. The shaft portion 25 has a columnar shaft 25a extending in the longitudinal direction of the razor head 3. By this shaft 25a, the razor head 3 is rotatably (swingably) supported with respect to the handle 2.

[0048] [Razor head 3] The razor head 3 includes a razor head pedestal 4, a blade cartridge 5, and a lid member 6.

[0049] [Razor head pedestal 4] The razor head base 4 of the razor head 3 is connected to the upper end of the handle 2 so as to be swingable, that is, swingable, with respect to the handle 2. A blade cartridge 5 is detachably arranged with respect to the razor head base 4. The razor head base 4 holds the blade cartridge 5 by sandwiching the blade cartridge 5 together with the lid member 6. This will be specifically described below.

[0050] The razor head base 4 extends in the width direction which is the longitudinal direction, and is oval-shaped with both ends in the width direction being semi-circular instead of rectangular. In other words, it can be said that the razor head base 4 has a rectangular shape with rounded corners. The razor head base 4 has a recess 45 that is recessed downward in the central portion in the width direction on the upper side, which is the side opposite to the lower side where it is connected to the handle 2 (see FIGS. 4 and 5, etc.).

[0051] FIG. 12 is an exploded perspective view of the razor head base 4. The razor head base 4 is composed of a first member 4a and a second member 4b. The first member 4a and the second member 4b are connected by two connecting portions 42b. The connecting portion 42b is, for example, a screw, but the first member 4a and the second member 4b may be connected by a configuration other than a screw. The connecting portion 42b is inserted into a through hole 42c which is a screw hole formed in the first member 4a and a screw hole 42d formed in the second member 4b. A magnet 44 and a spring 49, which will be described later, are accommodated between the first member 4a and the second member 4b.

[0052] As shown in FIGS. 5 and 12, the razor head base 4 has a first cover member base 41, a blade cartridge base 42, and a second cover member base 43. The second cover member bases 43 provided on the left and right sides of the blade cartridge base 42 provided at the central portion of the razor head base 4 are provided one step lower, and the first cover member base 41 provided at the peripheral portion of the razor head base 4 is provided further one step lower. The peripheral portion 66 (see FIG. 7) of the cover member 6 is placed on the first cover member base 41 so as to abut thereon. The magnet facing portion 64 (see FIG. 7) of the cover member 6 is placed on the second cover member base 43 so as to abut thereon. The second cover member base 43 is provided with a through hole through which the magnet 44 is exposed. The blade cartridge 5 is placed on the blade cartridge base 42. The razor head base 4 has a bilaterally symmetric configuration and has two through holes 42a and screw holes 42d into which two connecting portions 42b are inserted (see FIG. 12). Body hair removed by the blade 51 of the blade cartridge 5 flows through the through holes 42a.

[0053] As shown in the exploded view of FIG. 12, the razor head base 4 has, inside thereof, a shaft support portion 46 for swingably supporting the razor head 3 with respect to the handle 2. Specifically, the shaft support portion 46 is provided on the lower side of the second member 4b of the razor head base 4, which is opposite to the side where the recess 45 is formed. As described above, the shaft support portion 46 supports the shaft 25a so as to be in contact with the peripheral surface of the shaft 25a of the shaft portion 25 of the handle 2. A spring 49 is disposed near the center of the razor head base 4 in a plan view and on the back side of the first member 4a. The spring 49 shown here is a coil spring, but the spring 49 may be replaced with a spring or a biasing member other than the coil spring. One end of the spring 49 abuts on the first member 4a, and the other end abuts on the handle 2. The spring 49 elastically supports the razor head base 4 while biasing it with respect to the handle 2. Thereby, with the center of the shaft 25a as the rotation axis, the razor head 3 is swingable while being biased by the spring 49.

[0054] As shown in FIGS. 6 and 12, magnets 44 are arranged on both longitudinal ends in the width direction of the razor head base 4, i.e., on the sides of the through holes 42a. The magnets 44 are housed inside the blade cartridge base 42 and partially exposed to the lid member second base 43. Although details will be described later, the magnets 44 detachably adsorb the blade cartridge 5 and the lid member 6.

[0055] Near the four corners of the blade cartridge base 42 of the razor head base 4, blade cartridge movement restricting portions 48a to 48d are provided. By abutting against the corner portions 53c to 53f at the four corners of the blade cartridge 5, the blade cartridge 5 is restricted from moving so as not to be displaced relative to the blade cartridge base 42 on the surface forming the surface of the blade cartridge base 42. Thereby, the position of the blade cartridge 5 is stabilized.

[0056] [Blade Cartridge 5] The blade cartridge 5 is detachably arranged on the blade cartridge base 42 of the razor head base 4 by the magnets 44. The blade cartridge 5 includes a plurality of blades 51, a blade base 52, and a frame member 53. All of these members constituting the blade cartridge 5 are formed of metal and are recyclable.

[0057] The blade 51 extends in the width direction and has a blade tip formed on the lower side. The blade cartridge 5 has a plurality of blades, and in this embodiment, it has five blades 51, but this number may be arbitrarily changed. The blade 51 is supported by the blade base 52 and fixed to the blade base 52 by welding or adhesion.

[0058] The blade body pedestal 52 supports a plurality of blade bodies. The blade body pedestal 52 has bending portions 52a to 52d that extend in the width direction and bend toward the blade body cartridge pedestal 42 at the upper end and the lower end, which are both ends in the short side direction in the blade body cartridge 5. The bending portions 52a to 52d abut against the blade body cartridge pedestal 42, function as leaf springs, and bias the blade body cartridge 5 placed on the blade body cartridge pedestal 42 toward the front side, which is the side opposite to the blade body cartridge pedestal 42. Thereby, the position of the blade body cartridge 5 in the depth direction is stabilized.

[0059] The frame member 53 is a flat plate-shaped member formed so as to surround a plurality of blade bodies 51 and the blade body pedestal 52 in a plan view. The frame member 53 has a substantially rectangular and annular outer frame portion 53a along the shape of the blade body cartridge pedestal 42, and two connecting portions 53g and 53h that connect the outer frame portion 53a in the vertical direction, which is the short side direction. The frame member 53 has corner portions 53c to 53f that engage with the blade body cartridge movement restricting portions 48a to 48d when the blade body cartridge 5 is placed on the blade body cartridge pedestal 42. Among the corner portions 53c to 53f, the corner portions 53e and 53f formed on the lower side have a gently curved shape, while the corner portions 53c and 53d formed on the upper side have a shape with a notch.

[0060] The frame member 53 has a knob portion 53b formed so as to protrude from the recess 45 at a position facing the recess 45 of the blade body cartridge 5 when the blade body cartridge 5 is placed on the blade body cartridge pedestal 42. That is, the knob portion 53b is formed so as to protrude outward from the upper outer edge of the outer frame portion 53a of the frame member 53. This knob portion 53b can be a point of force contacted by the user when removing the blade body cartridge 5 placed on the blade body cartridge pedestal 42 from the blade body cartridge pedestal 42,

[0061] FIG. 9 is a plan view of the razor head 3. FIGS. 10 and 11 are cross-sectional views showing the positional relationship between the magnet 44, the razor head pedestal 4, and the lid member 6, and show the cross-sections taken along A-A and B-B of FIG. 9, respectively.

[0062] As shown in FIGS. 10 and 11, the magnet 44 is accommodated inside the razor head pedestal 4, and the distance D1 between the magnet 44 and the lid member 6 is shorter than the distance D2 between the magnet 44 and the blade cartridge 5. Therefore, the magnet 44 adsorbs the lid member 6 more strongly than the blade cartridge 5. The force required for the user to remove the lid member 6 from the razor head pedestal 4 is stronger than the force required to remove the blade cartridge 5 from the razor head pedestal 4. However, since the blade cartridge 5 is sandwiched between the razor head pedestal 4 and the lid member 6, the blade cartridge 5 does not fall off during use. Further, the lid member 6 abuts against the first pedestal 41 of the lid member of the razor head pedestal 4, and in the direction including the vertical direction in which the razor 1 moves during use, the movement is restricted by abutting against the outer edge of the blade cartridge pedestal 42.

[0063] The relationship between the distance D1 between the magnet 44 and the lid member 6 and the distance D2 between the magnet 44 and the blade cartridge 5 is preferably a relationship of 2 ≦ D2 / D1 ≦ 20, more preferably a relationship of 2 ≧ D2 / D1 ≧ 5. At this time, D1 is 0.10 mm or more and 0.25 mm or less, and D2 is 0.50 mm or more and 2.00 mm or less. By setting such a relationship, the balance between the strength with which the magnet 44 and the lid member 6 are adsorbed and the strength with which the magnet 44 and the blade cartridge 5 are adsorbed can be improved.

[0064] [Lid member 6] The lid member 6 is detachable from the razor head pedestal 4 and functions as a lid that sandwiches the blade cartridge 5 together with the razor head pedestal 4. As shown in FIG. 6 and the like, the lid member 6 has a shape similar to that of the razor head pedestal 4 in plan view, extends in the width direction which is the longitudinal direction, is not rectangular, and is oval with both end portions 62a and 62b in the width direction being semi-circular. Three-dimensionally, both end portions 62a and 62b in the width direction of the lid member 6 are each formed in a substantially 1 / 4 spherical shape and are gently curved as a whole.

[0065] The lid member 6 includes both end portions 62a and 62b, an upper portion 61, and a lower portion 63, and has an opening 6a at the center. In a state where the blade body cartridge 5 is attached to the razor head 3, the blade body 51 is exposed to the front side from this opening 6a. Both end portions 62a and 62b, the upper portion 61, and the lower portion 63 of the lid member come into contact with the user's skin surface during use together with the blade body 51.

[0066] In the lower portion 63 of the lid member 6, which is the portion on the side where the cutting edge of the blade body 51 faces with respect to the blade body 51, a plurality of groove portions 63a are formed so as to extend in a direction perpendicular to the direction in which the blade body 51 extends, that is, the moving direction (slide direction) during use. These groove portions 63a are formed by concave portions and convex portions provided so as to undulate in the width direction, and at least the surface in contact with the user's skin surface has a rounded shape without corners. Therefore, even when the groove portions 63a come into contact with the user's skin surface, it is configured not to feel uncomfortable. Also, during use, a smoother enters the groove portions 63a, and the razor head 3 can be moved smoothly.

[0067] The lid member 6 is formed of a mirror-finished metal, similarly to the handle 2. Since the lid member 6 is a part that catches the user's eye, by being formed of a mirror-finished metal similar to the handle 2, a sense of unity is achieved in the design, and a high-class feeling is given to the razor 1. Note that either the lid member 6 or the handle 2 may be mirror-finished. Also, the lid member 6 may be changed in shape and design according to the user's preference and usage. Thereby, it becomes possible to replace the lid member 6 with one that the user likes.

[0068] The above lid member 6 is configured such that the groove portions 63a are formed in the lower portion 63, but it may also be configured such that groove portions are formed in both the upper portion 61 and the lower portion 63.

[0069] In the razor 1 of the present embodiment, the weight of the blade cartridge 5 is preferably 0.5% or more and 10% or less of the entire razor 1 including the handle 2 and the razor head 3, and more preferably 2.0% or less. For example, if the total weight of the razor 1 formed of metal is about 100 g, the weight of the blade cartridge 5 is about 1 g. At this time, for example, the weight of the lid member 6 is about 10 g, and the weight of the handle 2 and the razor head pedestal 4 excluding the lid member 6 is about 80 to 90 g. According to such a razor with such a weight balance, it becomes a user-friendly razor with a suitable weight for use. In addition, since the weight of the blade cartridge 5, which is the replacement part, is small with respect to the total weight of the razor 1, an environmentally friendly razor 1 can be provided. When resin is used for the configuration of the razor 1 excluding the blade cartridge 5, the total weight of the razor 1 may be, for example, about 20 g. At this time, for example, the weight of the lid member 6 is about 2 g, and the weight of the handle 2 and the razor head pedestal 4 excluding the lid member 6 is about 15 to 18 g.

[0070] As shown in FIG. 7, the lid member 6 has magnet facing portions 64 formed to protrude toward the razor head pedestal 4 from the surfaces 62c and 62d on the back side of both end portions 62a and 62b, outside in the width direction. The magnet facing portions 64 are provided at positions facing the magnets 44 of the razor head pedestal 4 and are attracted by the magnets 44 when the razor head pedestal 4 and the lid member 6 are connected.

[0071] [Blade Cartridge Case 7] The blade cartridges 5 are provided by being stored in a plurality in the blade cartridge case 7. The blade cartridges 5 stored in the blade cartridge case 7 can be attached to the razor 1 by a simple method as described below.

[0072] FIG. 13 is a view showing the blade cartridge case 7. As shown in FIG. 13, the blade cartridge case 7 has a plurality of blade cartridge case pieces 7a to 7c. Each of the blade cartridge case pieces 7a to 7c is separable by a perforation 75. A protective seal 76 is attached to the blade cartridge case piece 7a before use. When the user uses a new blade cartridge 5, the user removes the protective seal 76 to expose the blade cartridge 5. The blade cartridge case pieces 7a to 7c have a bottom surface 71 and an outer edge surface 72. On the outer edge surface 72, the frame member 53 of the blade cartridge 5 housed in the blade cartridge case pieces 7a to 7c abuts and is placed. In this case, the blade 51 floats without abutting on the bottom surface 71. However, the blade 51 may abut on the bottom surface 71 and the frame member 53 may float with respect to the outer edge surface 72. The blade cartridge case pieces 7a to 7c have a knob portion storage region 73 that matches the shape of the knob portion 53b. The knob portion storage region 73 is formed as a surface continuous from the outer edge surface 72. A recess 74 is formed on the opposite side of the knob portion storage region 73.

[0073] The replacement of the blade cartridge 5 of the razor 1 by the user is performed as follows. First, the user removes the lid member 6 of the razor 1 to expose the blade cartridge 5. Next, the user touches the knob portion 53b of the blade cartridge 5 to remove the blade cartridge 5. Next, the user removes the protective seal 76 from any one of the blade cartridge case pieces 7a to 7c of the blade cartridge case 7. Next, the user inserts the blade cartridge movement restricting portions 48a to 48d of the razor head pedestal 4 into the four corners 77 of the blade cartridge case piece 7b. Thereby, the blade cartridge 5 is aligned at an appropriate position of the razor head pedestal 4, and the blade cartridge 5 is attracted to the razor head pedestal 4 by the magnet 44. Next, the user attaches the lid member 6 to the razor head pedestal 4 to which the blade cartridge 5 is attached. Thereby, the replacement of the blade cartridge 5 of the razor 1 is completed.

[0074] As described above, since the razor cartridge case 7 is provided with spaces at the four corners 77 of the housed razor cartridge 5 into which the razor cartridge movement restricting portions 48a to 48d can be inserted, the user can easily replace the razor cartridge 5 without causing misalignment. Further, since the razor cartridge case 7 can be made thin by the above configuration, the razor cartridge case 7 can be stored compactly.

[0075] [Razor Stand 8] FIG. 14 is a view showing a razor stand 8 for holding the razor 1 in an upright state.

[0076] The razor stand 8 is formed of metal and has a substantially frustum - of - cone shape with a through - hole 82 at the upper part into which the handle 2 of the razor 1 is inserted. The through - hole 82 is formed to extend in the vertical direction, and the razor stand 8 supports the handle 2 inserted into the through - hole 82 in an upright posture. The bottom surface 83 of the razor stand 8 is formed in a planar shape perpendicular to the vertical direction and can be stably placed on a horizontal place. The razor stand 8 has a recess 84 recessed so as to notch downward on the upper side in the vertical direction and a recess 85 recessed so as to notch upward on the lower side in the vertical direction.

[0077] The side surface of the razor stand 8 has a frustum - of - cone side surface portion 81 having a substantially frustum - of - cone shape and a flat surface portion 86 obtained by cutting a part of the side surface of the substantially frustum - of - cone shape with a plane along the vertical direction. Two magnets 87 are arranged at positions above and below in the vertical direction on the flat surface portion 86. The razor stand 8 can be installed on a wall surface formed of metal extending in the vertical direction by the attracting action of the magnets 87 by this flat surface portion 86. The frustum - of - cone side surface portion 81 is formed of mirror - finished metal. The entire razor stand may be mirror - finished.

[0078] In this way, the razor stand 8 can not only be placed on a horizontal place but also can be installed on a metal wall surface such as in a bathroom or a washroom.

[0079] Note that in the above, the extending direction of the through hole 82 is not limited to the perfectly vertical direction and may be inclined with respect to the vertical direction to such an extent that the handle 2 can be held in an upright posture.

[0080] Such a razor stand 8 forms a razor set with the razor 1, enabling the razor 1 to be used more conveniently, providing a sense of unity in design, and allowing it to be stored like a decorative item.

[0081] [Modification Example] The razor 1 of the present invention is not limited to the shape described in the above embodiment, and a part thereof may be deformed within a range not departing from the gist of the invention with respect to the shape of the embodiment.

[0082] For example, a configuration in which part or all of the handle 2 is formed of resin may be adopted. Even in this case, the recyclability of the blade cartridge 5 remains unchanged.

[0083] Also, regarding the relationship between the magnet 44, the blade cartridge 5, and the lid member 6, an air gap where no magnetic material is arranged may be adopted such that the magnet 44 adsorbs the lid member 6 more strongly than the blade cartridge 5, with the air gap being smaller between the magnet 44 and the lid member 6 and larger between the magnet 44 and the blade cartridge 5, thereby adjusting the adsorption force. Additionally, a configuration such as changing the shape or strength of the magnet 44 may be adopted.

[0084] [Features of the Razor 1] The razor 1 includes a handle 2 gripped by a user and a razor head 3. The razor head 3 has a razor head pedestal 4 provided at the upper end of the handle 2 and a blade cartridge 5 that is detachable from and recyclable with respect to the razor head pedestal 4. The blade cartridge 5 includes a plurality of blades 51, a blade pedestal 52, and a frame member 53, and all of these blades 51, blade pedestal 52, and frame member 53 are formed of metal. The blade pedestal 52 supports the plurality of blades 51.

[0085] According to such a blade body cartridge 5, it has a configuration that is easy to recycle. Also, by configuring the blade body cartridge 5 to have a frame member 53 that surrounds the blade body 51 and the blade body pedestal 52, the user can grasp the frame member to replace the blade body cartridge, making the replacement easier, and the blade body cartridge 5 can be replaced safely and easily. Further, since the frame member 53 of the blade body cartridge 5 is formed in a flat plate shape, it can be processed relatively easily, and the frame member 53 and the blade body cartridge 5 can be formed at a relatively low cost. Also, the configuration of the blade body cartridge that is the part to be replaced is minimized, and the load on the environment can be reduced. Thereby, while having a recyclable configuration, a relatively inexpensive blade body cartridge 5 can be provided. Furthermore, by configuring it to have a detachable lid member 6, it becomes possible to change the lid member 6 to one according to the user's preference.

[0086] Also, the blade body cartridge 5 has a knob portion 53b formed by the frame member 53 protruding outward from the outer edge so that the user can easily come into contact with it when removing the blade body cartridge 5 from the razor head pedestal 4. Therefore, a blade body cartridge 5 that can be replaced by the user simply and safely can be provided.

[0087] Also, the razor 1 has a magnet 44 that attracts the blade body cartridge 5 and the lid member 6, and the distance between the magnet 44 and the lid member 6 is shorter than the distance between the magnet 44 and the blade body cartridge 5. Therefore, the magnet 44 of the razor head pedestal 4 attracts the lid member 6 more strongly than the blade body cartridge 5, so that the blade body cartridge 5 comes off with a weaker force than the lid member 6 from the razor head pedestal 4. Therefore, during normal use, it is difficult to remove the lid member 6, and in a state where the lid member 6 is removed, the blade body cartridge 5 sandwiched between the razor head pedestal 4 and the lid member 6 can be easily removed. Thereby, a razor 1 with an easy-to-replace blade body cartridge 5 can be provided.

[0088] In addition, in the razor 1, the distance D1 between the magnet 44 and the lid member 6 and the distance D2 between the magnet 44 and the blade cartridge 5 are set to a relationship of, for example, 2 ≤ D2 / D1 ≤ 20. This can improve the balance between the strength with which the magnet 44 and the lid member 6 attract each other and the strength with which the magnet 44 and the blade cartridge 5 attract each other.

[0089] In addition, since the entire handle 2 is formed of metal, a razor 1 with a luxurious feel can be provided for the handle 2.

[0090] In addition, since the handle 2 is formed of mirror-finished metal, a razor 1 with an even more luxurious feel can be provided for the handle 2.

[0091] In addition, since the weight of the blade cartridge 5 is 0.5% or more and 10% or less, more preferably 0.5% or more and 2.0% or less, of the weight of the razor 1, a user-friendly razor 1 with a suitable weight for use can be provided. Also, since the weight of the blade cartridge 5, which is the replaceable part, is small relative to the total weight of the razor 1, an environmentally friendly razor 1 can be provided.

[0092] In addition, in the razor 1, both ends in the width direction of the razor head pedestal 4 are semi-circular, and the corners of the razor head pedestal 4 and the razor head 3 are rounded, so that the corners such as the razor head 3 do not hit the user's skin during use and cause discomfort. Also, a razor 1 with an excellent design can be provided.

[0093] In addition, in the razor 1, both end portions in the width direction of the lid member 6 are formed in a substantially 1 / 4 spherical shape, so that the corners such as the razor head 3 do not hit the user's skin during use and cause discomfort. Also, a razor 1 with excellent design and a luxurious feel can be provided.

[0094] In addition, in the razor 1, since the lid member 6 is formed of mirror-finished metal, a razor 1 with an even more luxurious feel can be provided.

[0095] Also, in the razor 1, the handle 2 is formed such that the area of the cross-section perpendicular to the direction in which the handle 2 extends increases as the handle 2 moves away from the razor head 3. As a result, the gripped handle 2 is difficult to slip out of the hand, and the razor 1 becomes stable and easy to use.

[0096] Also, in the razor 1, the lid member 6 has a groove portion 63a formed to extend in a direction perpendicular to the extending direction of the blade body 51 on the side where the cutting edge of the blade body 51 faces with respect to the blade body 51. Therefore, during use, a smoother fits into the groove portion 63a, and the razor head 3 can be smoothly moved.

[0097] Also, the razor 1 is configured such that the knob portion 53b is provided on the side opposite to the side where the cutting edge of the blade body 51 faces. With such a configuration, it is possible to prevent the user's hand from touching the cutting edge when replacing the blade cartridge 5, and the blade cartridge 5 can be replaced more safely.

[0098] Also, the razor 1 has a simple and luxurious design using metal as described above. That is, the razor 1 has a durable configuration with a metal handle 2, but by adopting a simple design, it can be provided as something that is not boring and can be easily used for a long time. Furthermore, by adopting a configuration having a handle 2 that can be used for a long time and a recyclable blade cartridge 5 that can be replaced at an appropriate timing, it is possible to significantly reduce waste compared to the conventional case, and a razor 1 that can achieve sustainable development goals considering the environment can be provided.

[0099] In addition, the razor 1 with the handle 2 formed of metal is preferably used as a razor set combined with a razor stand 8. The razor stand 8 is formed of metal and has a flat portion 86 formed in a planar shape along the vertical direction, a magnet 87 disposed on the flat portion 86, and a through hole 82 extending in the vertical direction into which the handle 2 of the razor 1 can be inserted and supported. Such a razor set can give a sense of unity to the designs of the razor 1 and the razor stand 8, and both can be stored like ornaments. Also, the design property of the set of the razor 1 and the razor stand 8 can be enhanced, and it can be stored so as to be displayed with an excellent aesthetic appearance rather than just a simple razor and stand. Furthermore, since the handle 2 and the razor stand 8 are formed of metal, they are easy to clean and the razor 1 and the razor stand 8 can be kept hygienic.
