[0006] Technical issues

[0007] However, the razor disclosed in Patent Document 1 has the following problem: because the blade is facing downwards, when the head comes into contact with the armpit, the plastic part of the head is more likely to come into contact with the armpit than the blade.

[0008] Therefore, the present invention was made in view of the above-mentioned problems, and its object is to provide a razor that makes it easy for the blade to come into contact with the recess under the armpit.

[0009] Methods for solving problems

[0010] The first feature of the present invention is a razor having a vertical direction formed by an upper side and a lower side, and a thickness direction formed by a surface side and a back side, wherein the razor includes: a head for mounting the blade body; and a handle portion, and the razor has: a placement surface that contacts a predetermined plane when the razor is placed on a predetermined plane; and a central surface that runs along the placement surface and through the center of the thickness direction of the handle portion, such that when the razor with the head mounted on the upper side is viewed from the side, the blade of the blade body faces the upper side from the central surface toward the placement surface, and when the razor with the head mounted on the upper side is viewed from the back side, the blade body is bent in a manner that protrudes toward the upper side.

[0011] Invention Effects

[0021] (First Implementation)

[0022] The following is for reference Figures 1 to 7 An embodiment of the present invention will be described below. Figure 1 This is a diagram illustrating an example of the overall structure of the razor 1 according to one embodiment. Figure 2 This is a side view of the razor 1 with its head 10 positioned on the upper U side. Figure 3 This is a diagram showing the razor 1 with its head 10 positioned on the upper side U, viewed from the rear side (S2). Figure 4 yes Figure 3 Sectional view A-A' Figure 5 yes Figure 3 Sectional view B-B' Figure 6 This is a diagram of razor 1 viewed from the top (U). Figure 7 This is a diagram illustrating the head 10 of a razor 1 according to one embodiment.

[0023] like Figure 1 As shown, the razor 1 of this embodiment includes: a head 10 for mounting the blade body 11; and a handle 20. Figure 1 As shown, the blade 11 is held and held by the head 10 and the handle 20.

[0024] In addition, such as Figure 2 As shown, the razor 1 has an up-down direction formed by the upper side U and the lower side D, and a thickness direction T formed by the surface side S1 and the back side S2.

[0025] In addition, such as Figure 2 As shown, the razor 1 has: a placement surface L1 that contacts the predetermined plane P when the razor 1 is placed on the predetermined plane P; and a central surface L2 that is located along the placement surface L1 and at the center in the thickness direction T of the handle portion 20. Alternatively, the central surface L2 may be parallel to the placement surface L1.

[0026] Among them, such as Figure 2 and Figure 5 As shown, when viewed from the side, the razor 1 with the head 10 disposed on the upper side U has the blade 11A of the blade body 11 configured to face upward (U) as it moves from the central surface L2 toward the placement surface L1.

[0027] In addition, such as Figure 3 (a) and Figure 3 As shown in (b), when viewed from the rear side S2, the razor 1 with the head 10 disposed on the upper side U is configured to be bent in a manner that protrudes upward to the upper side U.

[0028] Normally, when shaving underarm hair, the user makes the razor 1 contact the underarm recess from below. Therefore, according to the above structure, since the blade 11A is configured to face upward (U) from the central surface L2 towards the placement surface L1, the blade 11A easily contacts the root of the hair when the user makes the razor 1 contact the underarm recess from below. Furthermore, according to this structure, since the blade body 11 is curved in a way that protrudes upward (U), the user can easily make the blade 11A of the blade body 11 fit against the underarm recess.

[0029] like Figure 6 and Figure 7 As shown, the razor 1 can also have multiple comb-like components 30. Among them, such as... Figure 6 As shown, the multiple comb-tooth components 30 are configured such that, when the razor 1 is viewed from above U, they have a first interval T1 at the rear side S2 of the razor body 11 along the extending direction W of the head 10. Wherein, as... Figure 7 As shown, the multiple comb teeth 30 can also be formed into a ring shape.

[0030] Based on this structure, it is possible to shave after combing neatly curly armpit hair, etc., and the hair can be shaved smoothly.

[0031] like Figure 7 As shown, the head 10 may also have a protective part 12, which is configured to at least cover a portion of the blade 11A of the blade body 11.

[0032] According to this structure, since it has a protective part 12, it can prevent damage to the user's skin due to the side slip of the razor 1.

[0033] Among them, such as Figure 7 As shown, the protective part 12 is configured to cover the blade 11A of the blade body 11 with a second interval T2, and can be configured such that the first interval T1 is larger than the second interval T2. According to this structure, shaving can be done without damaging the skin.

[0034] like Figure 2 , Figure 4 and Figure 5 As shown, the handle portion 20 may have a shape that protrudes on the surface side S1 and is recessed on the back side S2.

[0035] Furthermore, the handle portion 20 may not be rod-shaped but rather oval-shaped. Specifically, for example... Figure 3 As shown, the razor 1 can be configured such that, when viewed from the surface side S1 and the back side S2, the width W of the handle portion 20 increases as it moves away from the head 10, and then narrows after passing the center in the vertical direction of the handle portion 20.

[0036] Based on the above structure, a shape that is easy for users to grip when shaving their armpits can be achieved.

[0037] like Figure 3 As shown, the back side S2 can be divided by a plurality of curved portions 21 that bend in a manner that protrudes upward to the U side, and a plurality of straight portions 22 that extend in the vertical direction.

[0038] According to this structure, the fingers that come into contact with the back side S2 are less likely to slip during use, making it easier to grip. Furthermore, the curved portion 21 protruding upwards (U) allows the user to determine the difference between up and down directions by touch without visual inspection. Therefore, the multiple straight portions 22 can suppress slippage in the width direction.

[0039] Among them, such as Figure 3 As shown, when viewing the razor 1 with its head 10 positioned on the upper side U from the rear side S2, the curved portion 21 and the straight portion 22 can form an inverted U-shaped rib. Figure 3 As shown, multiple ribs are arranged periodically in the extension direction W of the head 10, and multiple ribs are also arranged in the vertical direction. Additionally, as... Figure 3 As shown, adjacent ribs in the vertical direction are staggered by half a cycle in a certain period.

[0040] By providing such ribs, the handle portion 20 can be thinned, reducing the amount of material used, and the rigidity of the handle portion 20 can be provided for durability. This results in a handle portion 20 that can prevent finger slippage during use and provides a secure grip.

[0041] like Figure 2 and Figure 6 As shown, the radius of curvature R1 of the surface side S1 of the handle portion 20 when viewed from the side of the razor 1 is greater than the radius of curvature R2 of the surface side S1 of the handle portion 20 when viewed from the top U of the razor 1.

[0042] According to this structure, when gripping the handle portion 20, the fingers that come into contact with the surface side S1 can easily fit into the handle portion 20. In addition, even though the handle portion 20 is elliptical, due to the different radii of curvature, it is easy to grasp the orientation of the handle portion 20 by the touch of the fingers.

[0043] like Figure 2 As shown, it can be configured such that when the razor 1 is placed on a predetermined plane P, a gap S is formed between the lower end 20E of the handle portion 20 and the predetermined plane P.

[0044] According to this structure, by inserting a finger into the gap S, the user can easily grasp the razor 1 from a state where the razor 1 has been placed on the specified plane P.

[0045] The user makes contact with the handle portion 20 from one side of the handle portion 20 in the width direction, and makes the index finger, middle finger, ring finger and even the little finger contact the surface side S1, and the ventral side of the thumb contact the dorsal side S2, thereby being able to grasp the handle portion 20.

[0046] As a result, it can be gripped by holding the handle 20 with these fingers. With this grip, it is easy to operate and easy to shave armpit hair, even if the angle of the fingers relative to the handle 20 changes depending on the use of the razor 1. In addition, it is easy to use even for people with different hand sizes, such as elementary school students and adults, and people who are not used to using razors.

[0047] According to the razor 1 of this embodiment, the user can easily make the blade 11A of the razor body 11 come into contact with the recess under the armpit.

[0048] When shaving armpit hair, users sometimes raise their arms steadily to flatten the armpit before shaving, avoiding creating a concave area. However, keeping the arm raised for too long can be tiring and can sometimes create a concave area. Therefore, according to this embodiment, a razor 1 can be provided that makes shaving armpit hair easy even when a concave area is formed.

[0049] Shaving armpit hair is something that can be done by anyone, regardless of gender. Furthermore, many people, from teenagers (such as elementary school students) to adults, want to manage their armpit hair. According to this embodiment, a razor can be provided that allows individuals of all ages and genders to easily manage their own armpit hair.

[0050] One of the SDGs is “eliminating inequality among people and nations,” and the Razor 1 in this implementation is a product associated with it.

[0051] The present invention has been described in detail using the above embodiments, but it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes only and does not imply any limitation on the present invention.
