  Hereinafter, an example of an embodiment of a small bag according to the present application will be described with reference to the drawings. In the following description of some embodiments, description of the same components may be omitted.

<Embodiment 1>
FIG. 1 is a front view for explaining the small bag 1 according to the first embodiment. FIG. 2A is an enlarged front view of the blade edge portion, and FIG. 2B is an enlarged rear view of the blade edge portion. FIG. 2C is a cross-sectional view of the vicinity of the tip of the small rod 1. FIG. 2D is a cross-sectional view of the vicinity of the tip according to a modified example of the small rod 1.

  The small heel 1 is a tool for cutting short hairs such as nose hairs, eyebrows and tegus, and slippery threads. In the following description, it is assumed that the object to be cut is hair.

  The small bag 1 has a total length of 7 to 10 cm. However, depending on the purpose of use, it may be shorter or longer.

  The small itch 1 includes an action part 10, a handle part 30, and a connecting part 20 that connects the action part 10 and the handle part 30. The small bag 1 has two members (a first member M1 and a second member M2), and each of the members M1 and M2 includes an action portion 10, a connecting portion 20, and a handle portion 30. The two members M <b> 1 and M <b> 2 are fastened to each other at the connecting portion 20 with screws 40 so that the action portion 10 opens and closes according to the opening and closing of the handle portion 30.

  In addition, although the 1st member M1 and the 2nd member M2 are fastened here with the screw | thread 40 so that rotation is possible, they may be crimped and may be removable.

  In the handle portion 30, a ring-shaped finger ring 31 is formed on each of the first member M1 and the second member M2. In use, a thumb is put in one ring 31 and an index finger (or middle finger, ring finger) is put in the other ring 31 and operated. Convex contact protrusions 32 are formed at portions where the rings 31 collide with each other so as to face each other.

  The action portion 10 includes blades 12 and 17 at portions where the first member M1 and the second member M2 that are paired face each other. The blade span (length of the blade edge) of the blades 12 and 17 is usually 1 cm to 3.5 cm. The cutting edge is the thinnest part, and is the apex part in a sectional view.

  As shown in FIG. 3A, the action portion 10 of the first member M1 is formed with a blade 12 having a sharp cross section from the blade base 131 to the vicinity of the tip 132. Further, the anti-slip portion 11 is provided in the vicinity of the tip 132. The blade base 131 to the anti-slip portion 11 are linear blades.

  The anti-slip portion 11 includes a plurality of V-shaped concave portions 111 that are notched (depressed or depressed) with respect to the straight blade 12 at a predetermined interval.

  The depth of the recess 111 is a depth at which the hair to be cut is easily caught. The depth of the recess 111 is, for example, 0.2 to 1 mm. The space | interval of the adjacent recessed part 111 becomes like this. Preferably it is 0.3 mm-1.5 mm, More preferably, it is 0.5 mm-1.0 mm. The number of the concave portions 111 is 2 to 10, for example, five.

  The hair to be cut is caught in the recess 111. Therefore, the hair is prevented from slipping away from the blade edge when trying to cut, and can be easily cut.

  As shown in FIG. 2B, a linear blade 17 is formed on the action portion 10 of the second member M2 from the base of the blade to the vicinity of the tip 132.

  A blade is not provided at the distal end 132 of the first member M1 and the second member M2 on the action part 10 side. Further, the vicinity of the tip has a shape (semicircular shape) in which the dorsal side 14 expands in a round shape. That is, the tip 132 is not sharp but round. With this shape, it is possible to prevent the skin from being damaged even if the tip of the action portion 10 of the small heel 1 hits the skin.

  The small bag 1 of Embodiment 1 has been described above. According to the small scissors 1, since the blade is provided with the anti-slip portion 11, even a short slippery hair or thread can be easily cut.

  As a modification of the first embodiment, the small fold 1 can have a structure in which the cut hairs and threads have no cross-section. For example, as shown in FIG. 2D, the angle on the blade 17 side of the cross section of the second member M2 of the action portion 10 of the small heel 1 is close to 90 degrees, and functions as the cut surface crushing portion 18. The angle of the cross section of the blade 17 is, for example, 45 to 90 degrees, preferably 50 to 85 degrees, and more preferably 70 to 85 degrees.

  Here, the cut surface crushing portion 18 is provided in the second member M2, but the cut surface crushing portion 18 may be provided in the first member M1, and further, cutting is performed in both the first member M1 and the second member M2. A crushing portion 18 may be provided. Further, by increasing the thickness of the first member M1 and the second member M2, for example, from 1 mm to 2 mm, it is possible to perform crushing and crushing without opening a gap during cutting. The cross-sectional shape of each blade may be 90 degrees or more (for example, more than 90 degrees and 110 degrees or less).

  By setting it as the shape of such a blade, the cut surface of the cutting object does not become an acute angle, but seems to be crushed and cut. That is, the cut surface when hair or thread is cut with the small scissors 1 can be crushed, and the tip of the hair can be prevented from being sharp.

  For example, when the nose hairs are gradually stretched after cutting and the hair tips come into contact with the skin, a sharp sensation may occur due to the sharp shape. According to the small scissors 1 provided with the cut surface crushing portion 18 described above, it is possible to avoid the sharpness of the hair tip after cutting, so that “feeling of tingling” can be alleviated.

  In addition, when cutting a teg or the like, the cut portion is crushed and becomes cloudy white, so that the tip can be easily seen.

  As a further modification of the first embodiment, FIG. 3 (A) shows a substantially hemispherical hemispherical body 141 on the back side of the tip 132 of the blade edge. FIG. 3B shows a cross section of the hemispherical body 141. Here, a substantially hemispherical body is shown, but a substantially hemispherical body may be used. Further, FIG. 3C shows a structure provided with a plurality of semi-spherical bodies 141 and 142 having a substantially semi-circular shape. Further, although a substantially semicircular shape is shown here, a combination with a substantially semispherical shape may be used.

  It is also effective to smooth the surface by barrel polishing, sand blasting, and buffing as well as burrs on the contact surface that contacts the skin. These surfaces may be mirror-finished or the like, but the surface may be satin-finished (matte, hairline finish, etc.) due to differences in skin feel depending on the person.

  As a result, not only can damage to the skin be prevented, but also a sense of security and relief can be obtained when contacting the skin and mucous membranes.

<Embodiment 2>
FIG. 4A is an enlarged front view of the action portion 10a of the small jar 1a according to the second embodiment, and FIG. 4B is an enlarged rear view thereof. In addition, since a connection part and a handle | steering-wheel part are the same as that of Embodiment 1, description is abbreviate | omitted. 5A is an enlarged front view near the tip, and FIG. 5B is a cross-sectional view thereof.

  An anti-slip portion 11a is formed in the vicinity of the tip 132 of the first member M1 of the small bag 1a. The anti-slip portion 11a includes a plurality of convex blade portions 112a slightly protruding from the extension of the inner contour line 12p from the base 131p of the action portion 10a of the first member M1 toward the tip 132, and adjacent convex blade portions 112a. A groove (concave portion) 111a is formed between them. Note that a blade may or may not be formed on the inner contour line. Furthermore, the blade may or may not be formed on the corresponding portion on the second member M2 side that faces the other.

  The width L1 of the convex blade portion 112a is 0.2 mm to 1 mm, preferably 0.3 mm to 0.5 mm. The width L2 of the groove 111a is 0.2 mm to 1 mm, preferably 0.3 mm to 0.5 mm. The depth of the groove 111a is 0.3 mm to 1.5 mm, preferably 0.5 mm to 1 mm.

  An oblique cut blade (inner oblique blade 113a) is provided on the inner side (second member M2 side) of the convex blade portion 112a. The reason for this will be described. With the closing operation of the handle portion of the small rod 1a, the cutting edge of the first member M1 and the cutting edge of the second member M2 are sequentially contacted from the cutting edge toward the tip. At this time, the first member M1 and the second member M2 are configured to be twisted so as to slightly intersect so that the two cutting edges are surely in contact with each other. Since the convex blade portion 112a protrudes beyond the extension line of the blade at the base of the blade, when it closes to the vicinity of the anti-slip portion 11a, the blade of the second member M2 hits the convex blade portion 112a, and further closing operation is performed. It becomes difficult. Therefore, an oblique cut blade (inner oblique blade 113a) is provided on the inner side (second member M2 side) so that the closing operation is performed smoothly. At the same time, after cutting in such a way that the cut object is supported at the tip of 112a at the time of cutting, cutting is performed at the corners of the inner oblique blade 113a and the corner of 17 so that cutting is facilitated and tip sharpness can be prevented.

  The cutting edge crushing portion 18 can be provided on the cutting edge of the second member M2, similarly to the modified example of the small rod 1 of the first embodiment.

  According to the small heel 1a, even hair (thread) that slips and escapes easily at the time of cutting can be cut without escaping because the hair (thread) fits into the groove 111a. In addition, since the blade of the second member M2 is close to 90 degrees, the cut surface is crushed, and the “crimping feeling” after cutting can be suppressed. In addition, when the tegs are cut, the tip becomes easy to see due to white turbidity.

  FIG. 6A is an enlarged front view of the action portion 10b of the small rod 1b according to the modification of the second embodiment. As shown in the small ridge 1b, it has an anti-slip portion 11b and grooves 111b are formed in the blade 12 at predetermined intervals. The groove 111b can be rounded in a U shape at the bottom. As shown in FIG. 6B, the bottom may be a U-shaped corner groove 111b '. The cutting edge of the convex blade portion 112b is on the extension line without protruding from the extension line of the cutting edge of the blade 12 from the cutting edge 131 to the anti-slip portion 11b.

  The depth of the groove 111b is, for example, 0.2 to 1 mm. The interval between the grooves 111b is 0.2 mm to 1 mm, preferably 0.3 mm to 0.5 mm. The groove width L2 is 0.2 mm to 1 mm, preferably 0.3 mm to 0.5 mm.

  Similarly to the one shown in FIG. 5, an oblique cut blade (inner oblique blade) is provided on the inner side (second member M2 side) of the convex blade portion 112b.

  According to the small scissors 1b of the present embodiment, the object to be cut fits into the groove 111b, so that it can be cut without slipping out.

<Embodiment 3>
FIG. 7 is an enlarged front view of the action portion 10c of the small heel 1c according to the third embodiment.

  The small kite 1c is further provided with a slip prevention portion 11c near the tip of the second member M2 as compared with the small kite 1 of the first embodiment. The shape of the anti-slip part 11c is the same as that of the anti-slip part 11 of the first embodiment.

  With such a shape, when the blades of the action unit 10 approach each other as the handle unit 30 closes, the hair (thread) stays on the slip prevention units 11 and 11c without slipping and can be easily cut. .

  FIG. 8 shows a small bag 1d according to a modification of the third embodiment.

  An anti-slip portion 11d is formed on the second member M2 of the small rod 1d on the blade base 131 side of the position of the anti-slip portion 11 of the first member M1.

  According to the small ridge 1d, it is possible to prevent the object to be cut (hair or thread) from slipping at two different positions. Therefore, it becomes possible to cut more reliably without escaping the object to be cut.

  In addition, when forming a slip prevention part in both the 1st member M1 and the 2nd member, you may provide the slip prevention part of the same shape, and may provide the slip prevention part of a mutually different shape. Moreover, you may provide a slip prevention part in the blade of one member at intervals in several places.

<Embodiment 4>

  The blade of the second member M2 of the small scissors 1e includes a curved blade 17e that curves to the back side between the blade base and the tip.

  The curved blade 17e makes it easier for the cutting object (hair or thread) to stay on the curved portion, and functions as a slip prevention portion. And it can prevent that a cutting object escapes from between two blades.

  FIG. 9B shows a modification in which curved blades 17e and 12e are provided on both sides of the first member M1 and the second member M2.

  Furthermore, FIG.9 (C) provides the slip prevention part 11e which consists of a some groove | channel in the curved blade 12e of the 1st member M1 as a modification.

<Embodiment 5>
