Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the circular razor described in Patent Document 1, a circular blade with a special shape is required, and the manufacturing and development costs of the circular blade are high.

[0005] In addition, in the case of a circular blade, there is always a portion where the cutting edge is parallel to the moving direction of the circular razor during shaving. In a structure where the guard is only arranged at a position away from the cutting edge of the circular blade inside the circular blade, there is a risk of damaging the skin at that parallel portion. In particular, if the distance from the skin contact surface to the cutting edge in the circular razor is shortened so that the hair can be shaved close to the root, there is a risk of damaging the skin with the circular blade. Also, if the distance from the skin contact surface to the cutting edge is lengthened so as not to damage the skin, the hair cannot be shaved short. And if the skin contact surface is strongly pressed against the skin in an attempt to shave short, there is ultimately a risk of damaging the skin.

[0006] The trend of early use of hair removal tools is increasing. Through market research, it was found that most students from the fourth grade of elementary school to junior high school are concerned about unwanted hair, and many have experience in hair removal. However, regarding the use of razors by young children, not only the children themselves but also their parents are worried about injuries. Therefore, it is desired to realize a razor that has the safety of not causing injuries even when used by young users, can be intuitively and easily used for hair removal as if stroking the skin, and can be safely used by anyone, including those with visual impairments or weak grip strength, at a lower cost.

[0007] A first object of the present disclosure is to provide a razor capable of performing stroking shaving using a blade body having a linear blade edge without using a special circular blade. In addition, a second object is to provide a razor that can prevent more skin damage.

Means for Solving the Problems

[0008] The razor according to the first aspect of the present disclosure includes a plurality of blade bodies (10) having a linear blade edge (11) for hair removal, an opening (21) for exposing the blade edge in the blade body, a skin contact surface (25) that touches the skin, and a body portion (30) that is integrated with the skin contact surface and forms a hollow portion (33) connected to the opening. The openings are arranged in a regular polygon, and the blade edges of the plurality of blade bodies are arranged along each side of the regular polygon formed by the openings, so that the blade edges of the plurality of blade bodies are arranged facing each other in a regular polygon.

[0009] In this way, by arranging a plurality of blade bodies having a linear blade edge in a regular polygon instead of a special circular blade, a razor capable of performing hair removal over a wide area can be obtained by "stroking shaving" in which the skin contact surface is moved along the skin while directly touching the skin. And since the plurality of blade bodies are arranged in a regular polygon, no matter what direction the blade bodies are in during hair removal, it is possible to easily perform hair removal only by moving the razor while making the skin contact surface touch the skin.

[0010] In a second aspect of the present disclosure, there is provided a comb structure (315) having a plurality of comb teeth (315a) that cover the cutting edges of a plurality of blade bodies and protrude toward the inside of the opening relative to the covered cutting edges, such that hair passes through the comb teeth and then touches the cutting edge and is cut.

[0011] In this way, since the cutting edges of the plurality of blade bodies are each covered with comb teeth, it is possible to safely shave without damaging the skin. Further, since the razor has a structure in which a plurality of blade bodies are arranged in a regular polygonal shape and shaving can be performed regardless of the direction, there are not only blade bodies in which the cutting edge is nearly perpendicular to the direction of hair growth during shaving, but also blade bodies in which the longitudinal direction of the cutting edge is oriented along the direction of hair growth. However, even for a blade body in which the longitudinal direction of the cutting edge is oriented along the direction of hair growth, it is possible to safely shave by covering it with comb teeth.

[0012] In a third aspect of the present disclosure, the interval (I1) between the plurality of comb teeth is set to 1.0 mm or less, and the shortest distance (L1) from the skin contact surface to the cutting edge of the blade body is set to 0.15 mm or more. For example, the interval between the plurality of comb teeth is preferably 0.4 mm or more and 1.0 mm or less. The shortest distance is preferably 0.15 mm or more and 0.25 mm or less.

[0013] In this way, since the interval between the comb teeth is set to 1.0 mm or less, entry of the skin between the comb teeth is suppressed, and damage to the skin by the blade body can be prevented. If the interval between the comb teeth is 0.4 mm or more, a gap for the hair to enter between the comb teeth can be ensured. Further, since the shortest distance from the skin contact surface to the cutting edge is ensured to be 0.15 mm or more by the comb teeth, the cutting edge can be slightly separated from the skin, the cutting edge does not directly contact the skin, and the risk of damaging the skin can be further avoided. Also, if the shortest distance is 0.25 mm or less, it becomes possible to cut the hair at a position as close to the root as possible.

[0014] In a fourth aspect of the present disclosure, there are five or more blade bodies, the five or more blade bodies are arranged in a regular polygonal shape having five or more numbers of corners, and the opening is a regular polygonal shape having five or more numbers of corners.

[0015] In this way, since the blades are arranged in a regular pentagonal shape or a regular polygonal shape with more sides than a pentagon, it is possible to perform a good shaving regardless of the direction in which the hair grows. Further, if the number of blades is five, the arrangement of the blades and the shape of the openings become a regular pentagonal shape, and by increasing the number of blades, it is possible to prevent the size of the razor from becoming too large.

[0016] In a fifth aspect of the present disclosure, when shaving hair with any one of a plurality of blades while moving in an arbitrary moving direction while bringing the skin into contact with the skin contact surface, the angle formed by at least one cutting edge of the plurality of blades and the moving direction is 45 degrees or more.

[0017] In this way, by having any one of the cutting edges of the plurality of blades be 45 degrees or more with respect to the hair growth direction, it becomes possible to perform a good shaving. For example, if the blades are arranged in a regular pentagonal shape or a regular polygonal shape with more sides than a pentagon, regardless of the direction in which the hair grows, any one of the cutting edges of the plurality of blades will always be 45 degrees or more with respect to the hair growth direction.

[0018] In a sixth aspect of the present disclosure, the body portion has an arch-shaped cross-sectional shape and has a dome shape that is rotationally symmetric about the apex of the arch shape.

[0019] In this way, by making the body portion into a dome shape, the razor can be used by gripping it so as to wrap the entire body portion, making it easy to hold and use. Also, when shaving by moving the razor in various directions, since the dome shape, that is, the shape seen from above is circular, the moving direction of the razor is not specified by the shape, and shaving can be performed freely in any direction. Therefore, it is also possible to increase the degree of freedom in the operability of shaving. In particular, the treatment of stray hair is becoming more common among younger people, and there are cases where minors use razors. By making the body portion into a dome shape, it is possible to make the shape easy to use for the younger generation as well.

[0020] In a seventh aspect of the present disclosure, on the side of the body portion opposite to the skin contact surface, there is provided a gripping portion (40) that protrudes from the body portion to the opposite side and has an enlarged dimension in the plane direction of the skin contact surface at the protruding tip side.

[0021] In this way, if a gripping portion is provided, the razor can be held and used by utilizing the gripping portion. And by configuring the gripping portion in a shape that protrudes from the body portion to the opposite side and has an enlarged dimension in the plane direction of the skin contact surface at the protruding tip side, the gripping portion can be held in a fitting manner.

[0022] In an eighth aspect of the present disclosure, the body portion is provided with a communication hole (321) that connects the hollow portion and the outside of the body portion. By forming such a communication hole in the body portion, when water, shaved hair, etc. enter the hollow portion of the body portion, they can be discharged, and the razor can be kept clean.

[0023] In a ninth aspect of the present disclosure, the body portion has an arch-shaped cross-sectional shape and forms a dome shape centered on the apex of the arch shape, and a plurality of communication holes are formed side by side in the circumferential direction centered on the apex.

[0024] Further, when the body portion is a dome type with an arch-shaped cross section, if a plurality of communication holes are formed side by side in the circumferential direction centered on the apex of the arch shape, water and dirt can be discharged at any position. Furthermore, the communication holes serve as grips, improving the stability when holding the razor during shaving. In addition, the presence of the communication holes accentuates and can enhance the design of the razor.

[0025] In a tenth aspect of the present disclosure, there is a bottom portion (20) constituting a skin contact surface, and the body portion and the bottom portion are connected to sandwich a blade body therebetween. Further, the body portion has a comb structure and has a pressing portion (314a) that presses the blade body inside the blade body rather than the blade tip, and a clearance is provided between the comb teeth in the comb structure and the blade body on the blade tip side of the pressing portion in the blade body. And the bottom portion has a seat portion (22) that contacts the blade body and sandwiches the blade body together with the pressing portion, and at a location corresponding to the periphery of the blade body, while surrounding the seat portion, reaches an opening portion and has a flow path forming groove (24) recessed more than the seat portion.

[0026] In this way, by providing the flow path forming groove, a flow path during rinsing is configured. Therefore, it becomes possible to wash away hair with water flow through the flow path forming portion. And a clearance is provided between the comb teeth and the blade body, and even if hair shaved between the comb teeth and the blade body remains, it is not strongly sandwiched between the comb teeth and the blade body, so it can be easily washed away with water.

[0027] The razor in the eleventh aspect of the present disclosure has a linear blade tip (11), a plurality of blade bodies (10) for shaving, an opening portion (21) for exposing the blade tip of the blade body, a skin contact surface (25) that touches the skin, a body portion (30) that is integrated with the skin contact surface and constitutes a hollow portion (33) connected to the opening portion, and a plurality of comb teeth (315a) that protrude toward the inside of the opening portion rather than the covered blade tip while covering each of the blade tips of the plurality of blade bodies, and a comb structure (315) that allows the hair to pass through the comb teeth and then touch the blade tip and be cut, and the opening portion is arranged in a polygonal shape, and each of the blade tips of the plurality of blade bodies is arranged along each side of the polygonal shape constituted by the opening portion, so that the blade tips of the plurality of blade bodies are arranged facing each other in a polygonal shape.

[0028] In this way, by arranging a plurality of blade bodies having linear blade tips instead of special circular blades in a polygonal shape, a razor capable of shaving a wide area by stroking shaving can be formed. And since the plurality of blade bodies are arranged in a polygonal shape, no matter what orientation the blade bodies are in during shaving, shaving can be easily performed by stroking shaving. Furthermore, since the blade tips of the plurality of blade bodies are each covered with comb teeth, shaving can be safely performed without damaging the skin. Also, since the razor has a structure in which a plurality of blade bodies are arranged in a polygonal shape and shaving can be performed regardless of the direction, not only blade bodies whose blade tips are nearly perpendicular to the hair growth direction during shaving, but also blade bodies whose longitudinal direction of the blade tip faces along the hair growth direction exist. However, even for blade bodies whose longitudinal direction of the blade tip faces along the hair growth direction, it is possible to safely perform shaving by covering them with comb teeth.

[0029] Note that the reference signs in parentheses attached to each component etc. indicate an example of the correspondence relationship between the component etc. and the specific components etc. described in the embodiments described later.

Mode for Carrying Out the Invention

[0031] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In addition, in each embodiment including other embodiments described below, parts that are the same or equivalent to each other are denoted by the same reference numerals for explanation.

[0032] (First Embodiment) Hereinafter, the razor 1 according to the first embodiment of the present disclosure will be described with reference to FIGS. 1 to 9.

[0033] 〔Configuration of Razor 1〕 The razor 1 shown in FIGS. 1 to 3 enables shaving by stroking, and has a structure in which a body portion 30 is connected to a bottom portion 20 provided with a blade body 10, and is applied to shaving for the body, for example. As shown in FIG. 2, an opening 21 is formed in the bottom portion 20, the opening 21 is a regular polygon, and each of the plurality of blade bodies 10 is arranged on each side of the opening 21, so that the blade bodies 10 are also arranged in a regular polygon. In the present embodiment, five blade bodies 10 are provided, and the blade bodies 10 and the opening 21 are arranged in a regular pentagon. Hereinafter, the center line of the regular polygon formed by the opening 21 and the blade body 10 is referred to as the central axis C, and the circumferential direction is around the central axis.

[0034] Each blade body 10 has the same shape and is formed in a substantially rectangular plate shape as shown in FIGS. 4 and 5, with one side of the long side being the cutting edge 11. As shown in FIGS. 2 and 3, for the five blade bodies 10, the cutting edges 11 are exposed from the opening 21, and the cutting edges 11 are arranged in a regular polygonal shape facing each other. Inside the blade body 10, an oval long hole 12 with the major axis in the tangential direction with respect to the circumferential direction is formed. As shown in FIG. 5, the engaging projection 23 formed on the bottom portion 20 described later is inserted into the long hole 12, and the bottom portion 20 and the body portion 30 are attached. The minor axis dimension of the long hole 12 is made to match the dimension of the engaging projection 23, and each blade body 10 is held between the bottom portion 20 and the body portion 30 without play.

[0035] Note that a protruding portion 13 that partially protrudes is formed at one end side of the side of the blade body 10 opposite to the cutting edge 11. Therefore, as shown in FIG. 5, when the blade body 10 is arranged on the seat portion 22 of the bottom portion 20 described later, the front and back of the blade body 10 can be correctly attached, and the protruding portion 13 partially protrudes from the seat portion 22, making it easy to remove the blade body 10.

[0036] The bottom portion 20 is a member that constitutes a portion that exposes the blade body 10 and comes into contact with the skin during shaving. For example, it is configured as a resin molded product of a component, and has a circular dish shape with an opening in the central portion. The bottom portion 20 has a circular shape when the razor 1 is viewed from below as shown in FIG. 3, and has an opening 21, a seat portion 22, an engaging projection 23, a flow path forming groove 24, a skin contact surface 25, and a first locking portion 26 as shown in FIGS. 2 to 5.

[0037] The opening 21 is formed at the central position of the bottom portion 20 and is a regular polygon, here a regular pentagon, as described above. The regular polygon mentioned here does not mean a strict regular polygon but rather a substantially regular polygon. Specifically, the opening 21 has straight portions 21a that constitute five sides and discharge holes 21b located between the respective straight portions 21a, that is, at the corner portions of the regular polygon. The straight portion 21a is a portion along the cutting edge 11 of each blade body 10, and in the state where the blade body 10 is disposed on the bottom portion 20 as shown in FIGS. 3 and 5, the distance from the engaging projection 23 is set such that the cutting edge 11 protrudes toward the central axis C side from the straight portion 21a. Also, each straight portion 21a is set to be equal to or greater than the longitudinal dimension of the blade body 10. The discharge hole 21b has an opening at the corner portion of the regular polygon in a substantially circular shape and is connected to the flow path forming groove 24 to facilitate the discharge of water and dirt during the cleaning of the razor 1.

[0038] The seat portion 22 is a portion where the blade body 10 is disposed, and is provided at equal intervals at a plurality of locations, here five locations, along the circumferential direction centered on the central axis C, and extends in the radial direction from the straight portion 21a with respect to the central axis C. Specifically, the blade body 10 is disposed so as to abut on the surface 22a of the seat portion 22, and is inclined at an inclination angle, for example, of 10 degrees or more and 30 degrees or less, such that the surface 22a approaches the skin contact surface 25 as it approaches the straight portion 21a as shown in FIG. 6. For this reason, the blade body 10 disposed on the seat portion 22 abuts on the skin at that inclination angle, and shaving can be performed at a more easily shavable angle.

[0039] The engaging protrusion 23 is provided so as to protrude from the seat portion 22 at the central position of each seat portion 22, and is a portion for positioning the blade body 10. In the present embodiment, it also serves to integrate the bottom portion 20 and the body portion 30. The engaging protrusions 23 are arranged in three positions along the longitudinal direction of the blade body 10. Two protrusions 23a on both sides correspond to both ends of the long hole 12 of the blade body 10, and one protrusion 23b located between them is arranged at the central position of the long hole 12. As shown in FIG. 5, the protrusion 23a has a T-shaped cross section, and the tip is formed in an arc shape along the long hole 12, so that the blade body 10 is arranged on the seat portion 22 without displacement. The protrusion 23b is made higher than the protrusion 23a and has a cross-shaped cross section with a rounded tip. By being fitted into the body portion 30 prior to the protrusion 23a, it facilitates the positioning when connecting the bottom portion 20 and the body portion 30.

[0040] As shown in FIG. 5, the flow path forming groove 24 is formed so as to surround the seat portion 22 and reach the opening portion 21 at a location corresponding to the periphery of the blade body 10, and is constituted by a groove recessed from the seat portion 22. When the razor 1 is washed with water, dirt such as water and shaved hair is discharged through a path that bypasses the support wall 314, particularly through the flow path forming groove 24.

[0041] The skin contact surface 25 is one surface of the bottom portion 20 on the side opposite to the body portion 30, and is a surface that contacts the user's skin during shaving. The skin contact surface 25 may be either a curved surface or a flat surface, but it is preferably a curved surface that slightly protrudes toward the opposite side of the body portion 30 toward the central axis C side, so that when contacting the skin, the skin can be pressed and the cutting edge 11 of the blade body 10 can hit the root side of the hair. The above-mentioned opening portion 21 is opened at the central position of the skin contact surface 25.

[0042] The first locking part 26 is a connecting member that connects the bottom part 20 and the body part 30, and engages with a later-described second locking part 313 provided on the body part 30 side. In the present embodiment, the first locking part 26 is provided on the side of the bottom part 20 opposite to the skin contact surface 25, that is, on the body part 30 side, and stands upright toward the body part 30 at a position inside the outer edge of the bottom part 20. The number of the first locking parts 26 is arbitrary, but here it is five, the same number as the blade body 10. And each first locking part 26 is arranged on the outer side in the radial direction around the central axis C with respect to each blade body 10. Also, regarding the first locking part 26, the shape is arbitrary as long as it engages with the second locking part 313 on the body part 30 side, but here it is square-shaped and has a shape with a through hole 26a formed inside.

[0043] Note that, around the central axis C, on the outer peripheral side of the bottom part 20 rather than the first locking part 26, an annular flat surface 27 is formed, and a curved surface 28 in the shape of an R is formed between the flat surface 27 and the skin contact surface 25. As shown in FIG. 2, in the state where the bottom part 20 and the body part 30 are connected, the flat surface 27 is in close contact with the body part 30 and is hidden inside the razor 1, and the outer wall surface of the body part 30 and the curved surface 28 are connected as a seamless surface to form the outer wall of the razor 1.

[0044] The body part 30 is a member that is integrated with the blade body 10 and the bottom part 20 by being connected to the side of the bottom part 20 opposite to the skin contact surface 25. In the present embodiment, as shown in FIG. 4, the body part 30 is composed of two parts, a housing part 31 and a lid part 32, but it may also be composed of one part.

[0045] The housing part 31 is a member arranged between the bottom part 20 and the lid part 32, and is configured, for example, as a resin molded product of one part, and has a substantially circular tubular shape. The housing part 31 serves to connect the body part 30 to the bottom part 20, to sandwich the blade body 10 together with the bottom part 20, and to cover the cutting edge 11 of the blade body 10 to protect the skin from being damaged. Specifically, the housing part 31 has an outer edge part 311, a body part 312, a second locking part 313, a support wall 314, a comb structure body 315, a connecting protrusion 316, and the like.

[0046] The outer edge portion 311 is formed in a substantially circular tubular shape and constitutes a part of the outer shape of the razor 1. A plurality of connecting portions 311a protruding radially inward of the central axis C are provided on the inner peripheral side of the outer edge portion 311, and the body portion 312 is connected to the inner periphery of the outer edge portion 311 via these connecting portions 311a. The portion between the outer edge portion 311 and the body portion 312 that is not connected by the connecting portion 311a is a window portion 311b penetrating in the direction of the central axis C. The connecting portions 311a are formed at positions corresponding to between the plurality of blade bodies 10, and the positions corresponding to each of the plurality of blade bodies 10, that is, the positions corresponding to each of the first locking portions 26, are the window portions 311b.

[0047] The body portion 312 is a substantially circular tubular portion disposed inside the outer edge portion 311, and is a portion that integrates the portion constituting the second locking portion 313, the support wall 314, and the comb structure 315 with the outer edge portion 311. The second locking portion 313 is disposed at a position corresponding to the window portion 311b on the outer edge side of the body portion 312, and the support wall 314 and the comb structure 315 are disposed on the bottom portion 20 side of the body portion 312. In both directions along the central axis C, the body portion 312 protrudes more than the outer edge portion 311, the support wall 314 and the comb structure 315 are provided on the portion protruding toward the bottom portion 20 side, and the connecting protrusion 316 is provided on the portion protruding toward the lid portion 32 side. Further, the second locking portion 313 is provided so as to extend from the portion protruding toward the lid portion 32 side of the body portion 312 through the window portion 311b to the portion protruding toward the bottom portion 20 side. Further, the inner peripheral side of the body portion 312 is hollow and constitutes a part of the hollow portion 33 formed in the body portion 30.

[0048] The second locking portion 313 is a connecting member that connects the bottom portion 20 and the body portion 30 together with the first locking portion 26. In the present embodiment, the second locking portion 313 is shaped to extend from the outer peripheral wall of the body portion 312 toward the bottom portion 20 within the window portion 311b. More specifically, the second locking portion 313 has a proximal end 313a near the end face of the body portion 312 opposite to the bottom portion 20. From the proximal end 313a, it extends a predetermined distance radially outward of the body portion 312, and then bends back at a right angle and extends toward the bottom portion 20, thereby forming a locking piece 313b. Also, as shown in FIG. 6, a gap is formed between the locking piece 313b and the outer wall surface of the body portion 312, and the locking piece 313b is capable of elastic deformation. And at the tip position of the locking piece 313b opposite to the proximal end 313a, a convex portion 313c that protrudes on the side opposite to the body portion 312, that is, radially outside the central axis C, is provided. This convex portion 313c enters into the through hole 26a of the first locking portion 26, and the first locking portion 26 and the second locking portion 313 are locked together.

[0049] As shown in FIG. 4, the support wall 314 is formed by protruding the portion of the body portion 312 corresponding to the placement location of the blade body 10 toward the bottom portion 20. A pressing portion 314a is formed by the tip surface on the bottom portion 20 side of the support wall 314. The pressing portion 314a is inclined at the same inclination angle as the seat portion 22 formed on the bottom portion 20 with respect to the plane having the central axis C as the normal line so as to approach the skin contact surface 25 as it goes toward the central axis C. And by locking the first locking portion 26 and the second locking portion 313 together, the blade body 10 is clamped by the seat portion 22 and the pressing portion 314a at the bottom portion 20.

[0050] As shown in FIGS. 4 to 6, the support wall 314 has a linear portion 314b and a cylindrical portion 314c. The linear portion 314b is shaped along the cutting edge 11 of the blade body 10. The cylindrical portion 314c protrudes from the linear portion 314b toward the locking piece 313b at three positions: both ends and the center of the linear portion 314b. And the pressing portion 314a described above is constituted by the tips of these linear portion 314b and cylindrical portion 314c. Further, the support wall 314 is formed with engagement holes 314d and 314e into which the engagement protrusions 23 formed on the bottom portion 20 are fitted. The engagement holes 314d and 314e are formed inside each of the portions constituted by the three cylindrical portions 314c of the pressing portion 314a. Each of the engagement holes 314d and 314e is a circular hole having a position and dimensions corresponding to the three engagement protrusions 23. The engagement protrusions 23 are fitted into these engagement holes 314d and 314e, and the play between the housing portion 31 and the bottom portion 20 is suppressed by the close contact between the outer wall of the engagement protrusion 23 and the inner walls of the engagement holes 314d and 314e.

[0051] Furthermore, as shown in FIG. 6, the support wall 314 is sized to fit inside the blade body 10, and the portion outside the support wall 314 in the planar direction of the blade body 10 is hollow. Therefore, when the razor 1 is being cleaned, this hollow portion together with the flow path configuration groove 24 forms a flow path, making it easier to discharge water and dirt.

[0052] As shown in FIGS. 4 to 6, the comb structure 315 is composed of a plurality of comb teeth 315a protruding inward from the linear portion 314b in the support wall 314, that is, on the side opposite to the columnar portion 314c side. As shown in FIG. 7, each comb tooth 315a is arranged at equal intervals along the cutting edge 11 of the blade body 10. The interval I1 and the width W1 in the arrangement direction of each comb tooth 315a are arbitrary, but the interval I1 is set to be 0.4 mm or more and 1.0 mm or less, the pitch of each comb tooth 315a is set to be 0.8 mm or more and 2.5 mm or less, and the width W1 is set to be 0.4 mm or more and 2.0 mm or less. Further, as shown in FIG. 8, the tip of each comb tooth 315a protrudes beyond the straight portion 21a of the bottom 20 and protrudes bent toward the skin contact surface 25 side. The portion protruding toward the skin contact surface 25 side constitutes the cover portion 315b and covers the cutting edge 11. Specifically, as shown in FIG. 9, the cover portion 315b protrudes toward the skin contact surface 25 side to such an extent that it overlaps with the extension line of the cutting edge 11 in the plane direction of the blade body 10. And the shortest distance L1 from the skin contact surface 25 to the cutting edge 11 is 0.15 mm or more and 0.25 mm or less. Also, the protruding amount P1 of the comb tooth 315a from the cutting edge 11 radially inward with respect to the central axis C is arbitrary, but here the protruding amount P1 is set to be 0.5 mm or more and 1.2 mm or less.

[0053] Note that, as shown in FIGS. 7 to 9, the outer shape of each comb tooth 315a is generally rounded, and the tip of the cover portion 315b is also rounded. Therefore, the comb teeth 315a are shaped to be slippery on the skin surface and are less likely to catch on the skin and damage the skin during shaving.

[0054] Also, as shown in FIG. 6, the comb teeth 315a are separated from the blade body 10. Specifically, when viewed from the direction along the central axis C, the comb teeth 315a are separated from the blade body 10 over the entire area of the portion of the comb teeth 315a that overlaps with the flat surface portion of the blade body 10. That is, the pressing portion 314a protrudes more than the comb teeth 315a, and a clearance is provided between the comb teeth 315a and the blade body 10 on the cutting edge 11 side of the pressing portion 314a. Therefore, when shaving, a structure can be formed in which hair is less likely to be caught between the comb teeth 315a and the blade body 10.

[0055] The connecting protrusions 316 are provided so as to protrude radially outward with respect to the central axis C on the outer edge side of the portion of the body portion 312 that protrudes toward the lid portion 32 side from the outer edge portion 311, and a plurality of them are provided. Through this connecting protrusion 316, the lid portion 32 can be connected to the housing portion 31.

[0056] The lid portion 32 is connected to the housing portion 31 on the side opposite to the bottom portion 20 to constitute the body portion 30 together with the housing portion 31. The lid portion 32 has an arch-shaped cross-sectional shape when cut in the radial direction of the central axis C, and has a dome shape that is rotationally symmetric about the apex of the arch shape. The inside of the lid portion 32 is hollow and is connected to the hollow of the housing portion 31 to form a hollow portion 33. The lid portion 32 is provided with a communication hole 321 that connects the hollow portion 33 and the outside of the body portion 30, and water can be injected or discharged during washing of the razor 1. The communication holes 321 are formed in a plurality in the circumferential direction centered on the central axis C, that is, centered on the apex of the arch shape, and are arranged at equal intervals here. The shape of the communication hole 321 is arbitrary, but for example, it is a rectangular shape or an oval shape with the radial direction centered on the apex of the arch shape as the longitudinal direction.

[0057] Also, although not shown, a connecting groove or a connecting protrusion corresponding to the connecting protrusion 316 formed on the housing portion 31 is formed inside the lid portion 32, and the lid portion 32 can be connected to the housing portion 31.

[0058] Note that the end portion of the lid portion 32 on the housing portion 31 side is a ring-shaped flat surface 322 whose outer diameter is made to coincide with the outer edge portion 311 in the housing portion 31 with the central axis C as the center. Therefore, when the lid portion 32 is connected to the housing portion 31 as shown in FIG. 1, the flat surface 322 is in close contact with the outer edge portion 311 and is hidden inside the razor 1, and the outer wall surface of the housing portion 31 and the outer wall surface of the lid portion 32 are connected as a seamless surface to constitute the outer wall of the razor 1.

[0059] 〔Usage method of the razor 1〕 Next, the usage method of the razor 1 will be described. The razor 1 is used, for example, for shaving the body hair. The skin contact surface 25 is brought into contact with the part where shaving is desired, and the razor 1 is moved in an arbitrary moving direction while gently pressing the razor 1, in other words, shaving is performed by "stroking shaving" which is like stroking the skin. Since the razor 1 is provided with a polygonal opening 21 and the cutting edges 11 of the plurality of blade bodies 10 are arranged in a polygonal shape, when any one of the cutting edges 11 of the plurality of blade bodies 10 hits the hair, the hair is cut.

[0060] At this time, as shown in FIG. 3, if the advancing direction of the hair which is the reverse direction of the moving direction of the razor 1 is A1, it is preferable that the advancing direction A1 is perpendicular to the cutting edge 11 that cuts the hair, but it may be inclined with respect to the perpendicular direction. If the angle formed by the cutting edge 11 and the advancing direction A1 is 45 degrees or more, even if the cutting edge 11 is inclined with respect to the perpendicular direction to the advancing direction A1, the hair can be cut accurately. For this reason, in the present embodiment, the number of blade bodies 10 is five or more, and the arrangement of the blade bodies 10 is a regular pentagon or a regular polygon having more sides than that. In this way, no matter which direction the advancing direction A1 is facing, one of the cutting edges 11 of the plurality of blade bodies 10 will surely be 45 degrees or more with respect to the advancing direction A1, and it becomes possible to perform shaving well.

[0061] However, as the number of the blade bodies 10 increases, the size of the regular polygon formed by surrounding the plurality of blade bodies 10 becomes larger. In this case, the size of the skin contact surface 25 provided with the blade body 10 and the size of the body part 30 integrated with the skin contact surface 25 may become larger, and it may be difficult to hold by hand. For this reason, it is preferable to set the number of the blade bodies 10 to five and make the arrangement of the blade bodies 10 and the shape of the opening 21 a regular pentagon. In this way, while suppressing the size of the razor 1 from becoming too large, the advancing direction A1 of the hair when shaving can be made close to perpendicular to the cutting edge 11, and it becomes possible to perform shaving better.

[0062] If the cutting width, which is the length of the cutting edge 11, is reduced, even if the number of blade bodies 10 increases, it is possible to suppress an increase in the size of the regular polygon formed by surrounding the plurality of blade bodies 10. However, the area that can cut hair with one operation of the razor 1, in other words, the number of hairs that can be cut, decreases. For this reason, it is preferable to configure the cutting width of the blade body 10 to be a certain dimension, for example, 10 mm or more and 25 mm or less. By setting the cutting width to 10 mm or more, it is possible to prevent the amount of hair that can be cut with one operation of the razor 1 from becoming too small. Further, by setting the cutting width to 25 mm or less, it is possible to suppress an increase in the size of the razor 1 due to an increase in the area of the opening 21, and it is possible to avoid the razor 1 becoming too large and being difficult to hold or difficult to store.

[0063] [Effect of Razor 1] Hereinafter, the effects obtained when shaving using the razor 1 according to the present embodiment will be described.

[0064] (1) The razor 1 of the present embodiment includes a plurality of blade bodies 10 having linear cutting edges 11, and includes a skin contact surface 25 in which an opening 21 is formed, and a hollow portion 33 connected to the opening 21, and includes a body portion 30 integrated with the skin contact surface 25. The openings 21 are arranged in a regular polygon, and by arranging the respective cutting edges 11 of the plurality of blade bodies 10 along each side of the regular polygon formed by the openings 21, the respective cutting edges 11 are arranged facing each other in a regular polygon.

[0065] In this way, by adopting a configuration in which a plurality of blade bodies 10 having linear cutting edges 11 instead of special circular blades are arranged in a regular polygon, it is possible to obtain a razor 1 capable of shaving a wide area by stroking shaving. And since the plurality of blade bodies 10 are arranged in a regular polygon, no matter what direction the blade bodies 10 are in during shaving, it is possible to easily shave by simply moving the razor 1 while bringing the skin contact surface 25 into contact with the skin. And since it has a simple shape of a linear cutting edge 11, off-the-shelf products can also be used as the blade body 10.

[0066] In addition, since the blades 10 are arranged in a regular pentagonal shape or a regular polygon with more sides than a pentagon, no matter which direction the traveling direction A1 faces, there will always be one of the cutting edges 11 of the plurality of blades 10 that forms an angle of 45 degrees or more with respect to the traveling direction A1, enabling good shaving.

[0067] Furthermore, in the present embodiment, since the number of blades 10 is five and the arrangement of the blades 10 and the shape of the opening 21 are regular pentagonal shapes, it is possible to prevent the size of the razor 1 from becoming too large.

[0068] (2) The razor 1 is provided with a comb structure 315 having a plurality of comb teeth 315a that cover the cutting edges 11 of the plurality of blades 10 and protrude toward the inside of the opening 21 beyond the covered cutting edges 11, such that the hair passes through the comb teeth 315a and then touches the cutting edges 11 and is cut.

[0069] In this way, since each of the cutting edges 11 of the plurality of blades 10 is covered with the comb teeth 315a, shaving can be safely performed without damaging the skin. Also, since the razor 1 has a structure in which a plurality of blades 10 are arranged in a regular polygon and shaving can be performed regardless of the direction, not only the blades 10 in which the cutting edges 11 are nearly perpendicular to the hair traveling direction A1 during shaving, but also the blades 10 in which the longitudinal direction of the cutting edges 11 is along the hair traveling direction A1 exist. However, even for the blades 10 in which the longitudinal direction of the cutting edges 11 is along the hair traveling direction A1, safe shaving can be performed by covering them with the comb teeth 315a.

[0070] Moreover, the interval I1 between the plurality of comb teeth 315a is set to 1.0 mm or less, and the shortest distance L1 from the skin contact surface 25 to the cutting edge 11 is set to 0.15 mm or more. By setting the interval I1 between the comb teeth 315a to 1.0 mm or less in this way, the entry of the skin between the comb teeth 315a is suppressed, and the skin can be prevented from being damaged by the blades 10. Also, since the shortest distance L1 from the skin contact surface 25 to the cutting edge 11 is ensured to be 0.15 mm or more by the comb teeth 315a, the cutting edge 11 can be slightly separated from the skin, preventing the cutting edge 11 from directly contacting the skin and further avoiding the risk of damaging the skin.

[0071] (3) The body part 30 of the razor 1 according to the first embodiment has an arched cross-sectional shape and forms a dome shape that is rotationally symmetric about the apex of the arch shape.

[0072] In this way, by making the body part 30 into a dome shape, the razor 1 can be used by gripping it so as to wrap the entire body part 30, making it easy to hold and use. Also, when shaving by moving the razor 1 in various directions, since the dome shape, that is, the shape seen from above is circular, the moving direction of the razor 1 is not specified by the shape and shaving can be performed by freely moving it in any direction. Therefore, it is also possible to increase the degree of freedom in the operability of shaving. In particular, the prevalence of unwanted hair treatment among the younger generation is increasing, and there are cases where minors use it. However, by making the body part 30 into a dome shape, it can be made into a shape that is easy to use even for the younger generation.

[0073] Furthermore, since the regular polygonal opening 21 is formed in the skin contact surface 25, when the body part 30 is made into a dome shape, the razor 1 can be made into a design with a rounded and soft image. Therefore, even though the razor 1 is a cutting tool, it can give the user an impression of being gentle.

[0074] (4) The body part 30 is provided with a hollow part 33 and a communication hole 321 that connects the hollow part 33 and the outside of the body part 30. By forming such a communication hole 321 in the body part 30, when water, shaved hair, etc. enter the hollow part 33 of the body part 30, they can be discharged, and the razor 1 can be kept clean.

[0075] Also, when the body part 30 is made into a dome shape with an arched cross-section, if a plurality of communication holes 321 are arranged side by side in the circumferential direction centered on the apex of the arch shape, water and dirt can be discharged at any position. Furthermore, the communication hole 321 serves as a grip, improving the stability when holding the razor 1 during shaving. In addition, the presence of the communication hole 321 can accentuate and enhance the design of the razor 1.

[0076] (5) The body part 30 and the bottom part 20 are connected, and the blade body 10 is clamped by them. Specifically, the body part 30 is provided with a comb structure 315 having a plurality of comb teeth 315a, and is also provided with a pressing part 314a that presses the blade body 10 inside the blade body 10 rather than the blade tip 11. Further, the bottom part 20 is provided with a seat part 22, and the blade body 10 is clamped by the pressing part 314a and the seat part 22. And at a location corresponding to the periphery of the blade body 10, a flow path forming groove 24 that reaches the opening 21 while surrounding the seat part 22 is provided. Furthermore, a clearance is provided between the comb teeth 315a and the blade body 10 on the blade tip 11 side of the blade body 10 rather than the pressing part 314a.

[0077] In this way, by providing the flow path forming groove 24, a flow path during water washing is formed. Therefore, it becomes possible to wash away hair with water flow through the flow path forming groove 24. Also, since a clearance is provided between the comb teeth 315a and the blade body 10, even if there is hair shaved between the comb teeth 315a and the blade body 10, it can be prevented from being strongly clamped and can be easily washed away with water. Specifically, as shown by the thick arrow in FIGS. 5 and 6, when water is poured in from the communication hole 321, the cavity, clearance, and flow path forming groove 24 inside the razor 1 become the flow path, and the water can be easily flowed. For this reason, the razor 1 can be easily cleaned. Regarding the cleaning of the razor 1, the same effect can be obtained even if water is poured in from the opening 21 side instead of the communication hole 321 side and discharged from the communication hole 321 side.

[0078] (6) According to the razor 1 of this embodiment, hair shaving can be easily performed only by moving in an arbitrary moving direction while bringing the skin contact surface 25 into contact with the skin. In this way, since a razor 1 that is easy to use for anyone can be realized, it becomes easy to keep clean by dealing with unwanted hair, and it can contribute to Goal 3, "Good health and well-being for all", among the 17 goals in the SDGs (Sustainable Development Goals) adopted at the United Nations Summit.

[0079] In addition, the blade body 10 can be formed into a simple shape with a linear blade edge 11, and since an off-the-shelf product can be applied as the blade body 10, waste can be reduced, and it is possible to contribute to Goal 12, "Responsibility for Production and Consumption," of the SDGs. In addition, since the blade body 10 can be manufactured using existing equipment, the manufacturing process can be simplified, the amount of surplus material that is wasted can be reduced, etc., which also contributes to the contribution to Goals 12 and 13 of the SDGs.

[0080] (Second Embodiment) The second embodiment will be described. This embodiment is obtained by changing the structure of the body portion 30 and the like with respect to the first embodiment, and since the other aspects are the same as those of the first embodiment, only the parts different from the first embodiment will be described.

[0081] As shown in FIG. 10, the razor 1 of this embodiment includes a grip portion 40 that protrudes from the body portion 30 to the side opposite to the skin contact surface 25 on one surface of the body portion 30 that is opposite to the skin contact surface 25. The grip portion 40 may be integrally formed with, for example, the lid portion 32 of the body portion 30, or may have a structure that is connected to the lid portion 32.

[0082] The grip portion 40 has a structure in which the dimension in the plane direction of the skin contact surface 25 is enlarged on the tip side protruding from the body portion 30. Specifically, the grip portion 40 has a structure having a side surface 41 and a tip portion 42.

[0083] Taking the direction along the central axis C of the grip portion 40 as the height direction, the dimension in the plane direction of the skin contact surface 25 on the side surface 41 is gradually reduced as the height from the body portion 30 increases, and then gradually enlarged from the middle. That is, the side surface 41 has a constricted shape at a position in the middle in the height direction. The side surface 41 and the body portion 30 are seamless, and have a shape without steps or joints. The tip portion 42 has an elliptical shape when viewed from the direction along the central axis C, and is curved so as to gradually approach the body portion 30 side in one direction indicated by the arrow A2 in the figure from the central axis C.

[0084] In addition, in this embodiment, the thickness of the body part 30 is made thinner than that of the first embodiment, but the thickness of the body part 30 is arbitrary. Also, although the body part 30 does not have the communication hole 321, the communication hole 321 may be formed. Even in this case, the razor 1 can be cleaned by pouring water from the opening 21 side.

[0085] As described above, since the gripping part 40 is provided in this embodiment, the razor 1 can be held and used by utilizing the gripping part 40. For example, as shown in FIG. 11, the razor 1 can be held by wrapping the gripping part 40 with the hand, that is, while the thumb 51 touches the side surface 41, and covering the gripping part 40 with the whole of the other fingers. In this case, since the tip part 42 is curved so as to gradually approach the body part 30 in one direction, it matches the shape of the thumb 51 when gripping the razor 1, and the gripping part 40 can be held in a fitting manner.

[0086] Also, when using the razor 1 by holding it with the hand as shown in FIG. 12, while sandwiching the gripping part 40 between the index finger 52 and the middle finger 53, as shown in FIG. 13, use it by gripping the body part 30 with the thumb 51 or the like. Also in this case, since the side surface 41 has a constricted shape, it can be easily sandwiched between the index finger 52 and the middle finger 53, and the gripping part 40 can be held in a fitting manner. Also, since the tip part 42 is curved so as to gradually approach the body part 30 in one direction, it matches the shape of each finger when gripping the razor 1, and the gripping part 40 can be held in a more fitting manner. Then, while pressing the razor 1 in the direction of the skin as indicated by the arrow in the figure, shaving can be performed by stroking.

[0087] In this way, by providing the gripping part 40 on the side of the body part 30 opposite to the skin contact surface 25, it becomes possible to stably perform shaving while holding the gripping part 40.

[0088] (Other embodiments) The present disclosure is not limited to the above-described embodiments, and can be appropriately modified within the scope described in the claims. Also, in the above embodiments, it goes without saying that the elements constituting the embodiments are not necessarily essential, except when it is explicitly stated that they are essential or when they are considered to be clearly essential in principle. Further, in the above embodiments, when numerical values such as the number, numerical value, quantity, range, etc. of the components of the embodiments are mentioned, they are not limited to that specific number, except when it is explicitly stated that they are essential or when they are clearly limited to a specific number in principle. Also, in the above embodiments, when referring to the shape, positional relationship, etc. of components, etc., they are not limited to that shape, positional relationship, etc., except when it is explicitly stated or when they are clearly limited to a specific shape, positional relationship, etc. in principle.

[0089] For example, in each of the above embodiments, the body part 30 is provided with the comb structure 315, and the portions corresponding to the respective sides of the regular polygonal shape formed by the opening 21 in the bottom part 20 are made into the straight parts 21a. This is just an example, and a structure may also be adopted in which the linear part 314b in the pressing part 314a of the body part 30 is formed up to a position close to the cutting edge 11, and the bottom part 20 is provided with the comb structure.

[0090] Also, in each of the above embodiments, the cutting edge 11 is covered by the cover part 315b of the comb teeth 315a in the comb structure 315 to prevent the skin from being damaged. On the other hand, a configuration may also be adopted in which a sheet-shaped guard sheet having a plurality of holes formed along the cutting edge 11 is attached to the blade body 10, and the cutting edge 11 is exposed from the plurality of holes, while the guard sheet prevents the skin from being damaged.

[0091] Furthermore, in each of the above embodiments, the opening 21 is configured as a regular polygon, and the cutting edges 11 of the plurality of blade bodies 10 are also arranged side by side in a regular polygon. However, these only need to be polygons and do not necessarily have to be regular polygons. For example, for four sides of a pentagon, the same dimensions may be used, and the remaining one side may have a dimension longer or shorter than the other four sides. Also, when forming a polygon with an even number of corners having a plurality of pairs of parallel sides, it may be an elongated polygon in which one pair of opposite sides is longer than the other two pairs of opposite sides. As described above, when using a polygon that is not a regular polygon, a polygon can be formed by varying the dimensions of the blade body 10. Even in that case, although the sizes are different, the blade body 10 with a simple shape of a linear cutting edge 11 may be used, and off-the-shelf products can also be used.

[0092] Note that, as described above, the regular polygon described in each embodiment does not mean a strict regular polygon, but rather means that the overall contour shape is approximately a regular polygon. In each embodiment, since the opening 21 has a shape including a straight portion 21a and a discharge hole 21b, the shape of the opening 21 is not a strict regular polygon, but the overall contour shape is close to a regular polygon. Each side of the opening 21 is a straight portion 21a, but it may have a curved shape instead of a straight line, or a wavy shape. Similarly, although a regular polygon is formed by arranging the cutting edges 11 of the plurality of blade bodies 10 facing each other, there is a gap between the blade bodies 10, and the shape when the cutting edges 11 are arranged is not a strict regular polygon, but the overall contour shape is close to a regular polygon.
