Problems solved by technology

[0016] However, as in the razors of the above-mentioned Fig. 7 and Fig. 8, the first auxiliary slit 11 and the second auxiliary slit 12 are formed in the guard 8 of the razor 1, and the width of the main slit 13 is set to be greater than or equal to 0.8 mm. Under the situation of being less than 3.0mm, although women and beginners can safely use the razor, they cannot perform oblique shaving and deep shaving, and cannot achieve the improvement of shaving efficiency (1 shaving amount). For people who are used to it, they cannot use the razor satisfactorily. This is the first problem.
[0017] In addition, if the width of the main incision 13 is simply increased, in the case of oblique shaving or deep shaving, the blade 3a of the main incision 13 on the base end side may touch the skin and slightly cut the skin, which cannot Use it with confidence, this is the second question
[0018] In addition, even if the first auxiliary incision 11 and the second auxiliary incision 12 are formed in the guard 8 of the shaver 1, according to the user's operation method of trimming the line of the eyebrow and the ups and downs of the face, the parts exposed from the main incision 13 The part of the knife also has the possibility of touching the skin to cut the skin slightly, and there is a possibility of sliding sideways, which requires further safety in terms of structure
In particular, it is different from the usual method of using the handle 2 of the razor to hold the handle 2 of the razor in the manner of holding chopsticks to carry out trimming operations such as the eyebrows. In other methods of using the hair operation, the part of the knife exposed from the main incision 13 may touch the skin and slightly cut the skin, which is the third problem

Embodiment 1、2

[0174] Examples 1 and 2, Comparative Examples 1 and 2, and the first razor according to the present invention, as their configurations, are described in Table 1 and show the width of the cut and the ratio of the cut.

[0175] That is, the configuration of the razor in Example 1 has a first slit with a width of 5.0 mm, a second slit with a width of 1.0 mm, and a third slit with a width of 1.0 mm, and the proportion of the first slit is 70%. , the presence ratio of the second notch is set to 15%, and the presence ratio of the third notch is set to 15%.

[0176] The configuration of the razor in Example 2 has a first slit with a width of 3.5 mm, a second slit with a width of 1.0 mm, and a third slit with a width of 1.0 mm, and the presence ratio of the first slit is set to 90%. The ratio of the second notch was 5%, and the ratio of the third notch was 5%.

[0177] In addition, the configuration of the razor of Comparative Example 1 does not have the second slit and the third sli...

Abstract

The invention provides a razor tool with high security, which can meet the requirement of the people who has used before. A first razor tool of the invention is characterized in that cuts, which expose blades of a knife (3) in specified distance, are arranged on the knife (3) on a front end of a handle, and the razor tool can cover a guard (30) of a bridge of a blade on multiple parts. The cut of the guard (30) has a first cut (33) in the center of the blade, a second cut (34) less wide than the first cut at a front end side of the blade and a third cut (35) less wide than the first cut (33) at the side of a base end of the blade. A second razor tool of the invention is characterized in that cuts, which expose blades of the knife in specified distance, are arranged on the knife on a front end of a handle, and the razor tool can cover the guard of a bridge of a blade on multiple parts. The cuts of the guard has a first auxiliary cut (134) at a side of a front end of the blade, a second auxiliary cut (135) next to the first auxiliary cut and a third auxiliary cut (136) next to the second auxiliary cut and a plurality of main cuts (137) next to the third auxiliary cut; wherein, the first auxiliary cut is wider than the second auxiliary cut (135) and the second auxiliary cut is wider than the third auxiliary cut (136).

Description

technical field [0001] The present invention relates to razors. Background technique [0002] FIG. 4 shows a razor 1 mainly used by women in recent years to shave hair on the face surface or trim eyebrow lines. [0003] Such a razor 1 is composed of a handle 2 to be held by the user's hand, and a knife 3 attached to the front end of the handle 2 . [0004] Usually, in such a razor 1, a guard 4 is mounted on the blade 3a so that even if the user mistakenly operates the razor 1 in the direction of the blade 3a with the blade 3a in contact with the skin, It will not damage the skin either. [0005] The guard 4, generally shown in Figure 5 and Figure 6, is formed on a thin plate-shaped stainless steel sheet 5 whose length is shorter than the length of the blade 3a, so as to form a plurality of elongated blades extending along the width direction. The form of the bridge 7 is formed by punching a plurality of notches 6 along the longitudinal direction. [0006] When installing...
