Abstract
Description
Technical Field
[0001] The present invention relates to a pusher.
Background Art
[0002] When forming a gel nail on the fingertip nail, after applying a liquid made of synthetic resin on the nail, the light of a dedicated LED light is irradiated to cure the applied liquid. A loose cuticle (also called cutin or epidermis) is formed in a portion near the nail cuticle on the surface of the nail. If the loose cuticle is not removed and the synthetic resin is applied on the loose cuticle to form a gel nail, there is a problem that the completed gel nail will lift up as the loose cuticle grows.
[0003] Therefore, as a pretreatment before forming a gel nail, an operation of removing the loose cuticle from the surface of the nail is performed using an instrument called a pusher (see Patent Document 1). That is, the tip of the pusher is inserted between the surface of the nail and the loose cuticle, and the removal operation is performed by pushing up the loose cuticle. Further, the pusher is also used when removing the gel nail from the nail (gel off).

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, conventional cuticle pushers have sharp, pointed tips, which means that even when used to push back loose cuticles, the tip doesn't get between the nail surface and the cuticle. Instead, it rides up on top of the cuticle, making it difficult to remove. Furthermore, when the sharp tip of the pusher rides up on top of the loose cuticle, it's easy for that sharp tip to hit the skin of the finger.
[0006] The aforementioned problems also apply when removing gel nails using a pusher. In other words, conventional pushers have sharply pointed tips, so even when trying to push up the gel nail, the tip does not get between the nail surface and the gel nail, but instead rides up on top of the gel nail, making it difficult to remove. Furthermore, when the sharp tip of the pusher rides up on top of the gel nail, it is also likely to come into contact with the skin of the finger.
[0007] From this perspective, the object of the present invention is to provide a pusher that is less likely to get stuck on loose cuticles or gel nails on the nail surface and that can suitably remove loose cuticles and gel nails. [Means for solving the problem]
[0008] To solve the aforementioned problems, the present invention provides a shaft portion that serves as a handle, and a preparation portion provided at the end of the shaft portion for pushing up and removing the loose cuticle of the nail, wherein the preparation portion has a substantially arc shape in which the tip is convex in the direction away from the shaft portion when viewed from above, and comprises a pair of edges provided on both sides, a nail-facing surface that faces the nail and is curved so as to be convex in the direction away from the nail, an opposite surface which is the surface opposite to the nail-facing surface, and a rising surface that rises up from the nail-facing surface. The roughness of the aforementioned rising surface is set by polishing with abrasive materials of JIS R6252 900 to 1100 grit. It is characterized by the following:
[0009] Furthermore, the present invention comprises a shaft portion that serves as a handle, and a gel-removing portion provided at the end of the shaft portion for removing gel nails adhering to the nail, wherein the gel-removing portion has a substantially arc shape in which the tip is convex in a direction away from the shaft portion when viewed from above, and comprises a pair of edges provided on both sides, a nail-facing surface that faces the nail and is curved so as to be convex in a direction away from the nail, an opposite surface which is the surface opposite to the nail-facing surface, and a rising surface that rises from the nail-facing surface. The roughness of the aforementioned rising surface is set by polishing with abrasive materials of JIS R6252 900 to 1100 grit. It is characterized by the following:
[0010] Furthermore, the present invention comprises a shaft portion that serves as a handle, a preparation portion provided at one end of the shaft portion for pushing up and removing the loose cuticle of the nail, and a gel-off portion provided at the other end of the shaft portion for removing gel nail adhering to the nail, wherein at least one of the preparation portion and the gel-off portion has a substantially arc shape in which the tip is convex in a direction away from the shaft portion when viewed from above, and comprises a pair of edges provided on both sides, a nail-facing surface that faces the nail and is curved so as to be convex in a direction away from the nail, an opposite surface which is the surface opposite to the nail-facing surface, and a rising surface that rises from the nail-facing surface. The roughness of the aforementioned rising surface is set by polishing with abrasive materials of JIS R6252 900 to 1100 grit. It is characterized by the following:
[0011] According to the present invention, since the raised surface of the preparation portion is raised relative to the nail-facing surface, when the tip of the preparation portion is applied to the tip of the loose cuticle of the nail, the tip of the preparation portion is less likely to ride up on the loose cuticle, and the loose cuticle is easier to lift. Furthermore, since the lifted loose cuticle makes contact with the raised surface over its entire surface, it provides resistance to the movement of the pusher, thus avoiding contact between the preparation portion and the skin. Furthermore, according to the present invention, since the raised surface has a moderate roughness, it makes good contact with loose cuticles or gel nails, making them easy to peel off.
[0012] Similarly, because the raised surface of the gel removal tool is raised relative to the nail-facing surface, when the tip of the gel removal tool is applied to the tip of the gel nail, the tip of the gel removal tool is less likely to ride up on the gel nail, and the gel nail is easier to lift. In addition, the lifted gel nail makes contact with the raised surface over its entire surface, which provides resistance to the movement of the pusher and helps to avoid contact between the gel removal tool and the skin. Furthermore, according to the present invention, since the raised surface has a moderate roughness, it makes good contact with loose cuticles or gel nails, making them easy to peel off.
[0014] Furthermore, the rising surface rises approximately perpendicular to the claw-facing surface, and grinding is performed relative to the rising surface. Polish Preferably, the processing is carried out over the entire width and height of the aforementioned rising surface. According to the present invention, since the raised surface is raised at an appropriate angle, it makes good contact with the loose cuticle or gel nail, making it easy to peel it up. [Effects of the Invention]
[0015] According to the present invention, it is possible to provide a pusher that is less likely to get stuck on loose cuticles or gel nails on the nail surface and can suitably remove loose cuticles or gel nails. [Brief explanation of the drawing]

Mode for Carrying Out the Invention
[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is an overall plan view of the pusher according to this embodiment, Figure 2 is an overall bottom view, and Figure 3 is an overall front view. This pusher 1 is a shaft-shaped instrument made of metal or resin that is small enough to be held in one hand. In this embodiment, the shaft portion 2 is cylindrical, but it may have other cross-sectional shapes such as a rectangular prism or an ellipse. Since the pusher 1 is used by holding it in one hand, for example, like a writing instrument, it is desirable that the size and shape of the shaft portion 2 be such that it is easy to hold in the hand. The outer surface of the shaft portion 2 is covered with minute bumps and grooves to prevent slipping.
[0018] A preparation section 3 is formed at one end of the shaft section 2. The preparation section 3 is the part used to push up and remove the loose cuticle of the nail as a preliminary treatment before forming gel nail on the nail. A gel removal section 4 is formed at the other end of the shaft section 2. The gel removal section 4 is the part used to remove gel nail that is attached to the nail. The uses of the preparation section 3 and gel removal section 4 described above are merely the main uses and are not limited to these.
[0019] First, let's explain the configuration of the preparation section 3. Figure 4 is an enlarged plan view of the preparation section, Figure 5 is an enlarged bottom view thereof, Figure 6 is an enlarged front view thereof, Figure 7 is an enlarged cross-sectional view of AA in Figure 1, Figure 8 is a right side view of the preparation section, and Figure 9 is a partial enlargement of Figure 7.
[0020] As shown in Figures 4 and 5, the preparation portion 3 comprises edge portions 11, 11, a claw-facing surface 14, an opposite surface 16, and a rising surface 13. The preparation portion 3 extends in a spatula shape in the axial direction of the shaft portion 2 and gradually thins from the base end to the tip end (see Figure 7). Furthermore, it is roughly arc-shaped so that the tip 12 is convex when viewed from above.
[0021] On both sides of the preparation section 3, there are linear edges 11, 11 that extend from the base end to the tip 12 of the preparation section 3. These two edges 11, 11 widen outwards from each other as they approach the tip 12 of the preparation section 3 (Figures 4 and 5). As a result, the preparation section 3 becomes wider as it approaches the tip 12. In other words, when viewed from above, the edges 11, 11 are inclined to be closer to each other as they approach the base end of the preparation section 3.
[0022] The angle θ1 of the corner 18, which is formed by the edge 11 and the tip 12 (rising surface 13), is set to, for example, 90 to 110°, more preferably 95 to 105°. As shown in Figure 5, the nail-facing surface 14 is the surface that faces the nail when removing loose cuticle, and in plan view it has a roughly triangular shape. Also, as shown in Figure 8, the nail-facing surface 14 is curved so as to be convex in the direction away from the nail, following the shape of the nail.
[0023] As shown in Figures 4 and 5, the opposite surface 16 is the surface opposite to the claw-facing surface 14. The opposite surface 16 has a roughly trapezoidal shape in plan view. As shown in Figure 8, the opposite surface 16 is curved so as to be convex in the direction away from the claw.
[0024] As shown in Figure 9, the rising surface 13 is a surface that rises from the claw-facing surface 14 toward the opposite surface 16. When viewed from the side, the rising surface 13 is approximately perpendicular to the claw-facing surface 14. Also when viewed from the side, the rising surface 13 is approximately perpendicular to the opposite surface 16. The height of the rising surface 13 can be set as appropriate, but for example, it is about 0.5 to 3.0 mm, more preferably 1.0 to 2.0 mm.
[0025] The angle of the rising surface 13 with respect to the nail-facing surface 14 does not necessarily have to be a right angle, and can be set appropriately within a range that allows for suitable removal of loose cuticles or gel nails. The angle of the rising surface 13 with respect to the nail-facing surface 14 is preferably 80 to 100°, and more preferably 85 to 95°. Similarly, the angle of the rising surface 13 with respect to the opposite surface 16 does not necessarily have to be a right angle, and can be set appropriately.
[0026] The rising surface 13 is polished to JIS R6252 900-1100 grit. Polish Grinding by materials Polish The surface is finished by processing. In particular, a grit of approximately JIS R6252 1000 is most preferred. This surface finish is applied to the entire width and height of the rising surface 13.
[0027] Next, the configuration of the gel removal section 4 will be explained. Figure 10 is an enlarged plan view of the gel removal section, Figure 11 is an enlarged bottom view thereof, Figure 12 is an enlarged front view thereof, Figure 13 is a cross-sectional view of BB of Figure 1, Figure 14 is an enlarged left side view of the gel removal section, and Figure 15 is a partial enlargement of Figure 13. As shown in Figures 10 to 15, the gel-removing portion 4 comprises edge portions 22, 22, a nail-facing surface 26, an opposite surface 24, and a rising surface 23. The gel-removing portion 4 extends in a spatula shape in the axial direction of the shaft portion 2 and gradually thins from the base end to the tip 21 (see Figure 13). Also, as shown in Figures 10 and 11, it is roughly arc-shaped so that the tip 21 is convex when viewed from above.
[0028] Both sides of the gel-removing portion 4 are provided with parallel edges 22, 22 that extend from the base end to the tip 21 end of the gel-removing portion 4. The edges 22, 22 may be formed so that they are wider on the tip 21 side, or so that they are wider on the base end side.
[0029] The angle θ2 of the corner 28, which is formed by the edge 22 and the tip 21 (rising surface 23), is set to, for example, 120-130°. Comparing the preparation section 3 and the gel-off section 4, the angle θ1 < angle θ2 is set.
[0030] As shown in Figure 13, the nail-facing surface 26 is the surface that faces the gel nail when removing the gel nail. Also, as shown in Figure 14, the nail-facing surface 26 is curved so as to be convex in the direction away from the nail, following the shape of the nail.
[0031] As shown in Figure 11, the opposite surface 24 is the surface opposite to the claw-facing surface 26. As shown in Figure 14, the opposite surface 24 is curved so as to be convex in the direction away from the claw. As shown in Figure 15, the rising surface 23 is a surface that rises from the claw-facing surface 26 toward the opposite surface 24. When viewed from the side, the rising surface 23 is approximately perpendicular to the claw-facing surface 26. The height of the rising surface 23 can be set as appropriate, but for example, it is about 0.5 to 3.0 mm, more preferably 1.0 to 2.0 mm.
[0032] The angle of the rising surface 23 relative to the nail-facing surface 26 does not necessarily have to be a right angle, and can be set appropriately within a range that allows for suitable removal of loose cuticles or gel nails. The angle of the rising surface 23 relative to the nail-facing surface 26 is preferably 80 to 100°, and more preferably 85 to 95°. Similarly, the angle of the rising surface 23 relative to the opposite surface 24 does not necessarily have to be a right angle, and can be set appropriately.
[0033] The rising surface 23 is polished with JIS R6252 900-1100 grit sandpaper. Polish Grinding by materials Polish The surface is finished by processing. In particular, a grit of approximately JIS R6252 1000 is most preferred. This surface finish is applied to the entire width and height of the rising surface 13.
[0034] Next, the effects of this embodiment will be described. Figure 16 is a front view illustrating the method of using the preparation part 3. Figure 17 is a plan view thereof. Figure 18 is an enlarged longitudinal cross-sectional view of the loose cuticle and the tip of the preparation part in this case. The preparation part 3 is used as a preliminary treatment before forming gel nails, to remove the loose cuticle 104 from the surface of the nail 102 near the cuticle 103 at the base of the nail 102 of the finger 101. The loose cuticle 104 is formed in a roughly arc shape along the contour of the nail 102. The loose cuticle is also called keratin, and it grows so that its area gradually expands.
[0035] First, hold the shaft portion 2 of the pusher 1 in your hand, position the claw-facing surface 14 side facing the claw 102, and place the tip 12 of the preparation portion 3 against the tip of the loose cuticle 104. At this time, it is desirable to set the angle θ between the axial direction of the preparation portion 3 and the surface of the claw 102 to approximately 30° or less. In other words, conventionally the angle θ was set to around 45°, but it is preferable to lay the pusher 1 flatter and work with the rising surface 13 standing upright relative to the claw 102.
[0036] Furthermore, since the tip 12 is arc-shaped so as to be convex, the tip 12 faces the loose cuticle 104 so as to follow its contour. The corner portion 15 (see Figures 8 and 18), formed by the rising surface 13 and the nail-facing surface 14, contacts the tip of the loose cuticle 104 linearly across its width. Here's the problem with conventional cuticle pushers: because the tip is sharply pointed (without a raised surface), even when trying to push up the loose cuticle, the tip doesn't get between the nail surface and the loose cuticle, but instead rides up on top of the loose cuticle, making it difficult to remove. Also, when the pointed tip of the pusher rides up on top of the loose cuticle, it's easy for that pointed tip to hit the skin of the finger. Furthermore, even if the tip does get between the nail surface and the loose cuticle, because the tip is sharply pointed, it's easy for it to hit the skin of the finger with too much force (or go in too far and injure the finger).
[0037] In this respect, according to this embodiment, since the rising surface 13 rises relative to the nail-facing surface 14, when the tip 12 of the preparation part 3 is applied to the tip of the loose cuticle 104 of the nail 102, the tip 12 of the preparation part 3 is less likely to ride up on the loose cuticle 104, and the loose cuticle 104 is easier to lift up. Furthermore, since the lifted loose cuticle makes contact with the rising surface 13 over its surface, it provides resistance to the movement of the pusher 1, preventing the preparation part 3 from coming into contact with the skin with excessive force.
[0038] Furthermore, the preparation portion 3 is curved so as to be convex in the direction away from the nail 102, and the tip 12 is a substantially arc shape that is convex in the direction away from the shaft portion 2. Therefore, it matches the shape of the loose cuticle 104, making it easy to lift the loose cuticle 104. Thus, the loose cuticle 104 can be suitably removed by the preparation portion 3.
[0039] Furthermore, as shown in Figure 17, the pair of edges 11 are inclined to approach each other as they move toward the base end of the preparation section 3. In other words, the angle θ1 < angle θ2. This allows for fine processing using the relatively sharp corners 18. For example, the area near the boundary X between the end of the loose cuticle 104 and the finger 101 is a difficult area to process, but this can be easily done by using the corners 18 of the preparation section 3.
[0040] Furthermore, as shown in Figure 18, the preparation section 3 has a rising surface 13 that is polished with abrasive material of JIS R6252 900 to 1100 grit. Polish The surface is then finished. With abrasives of a grit lower than 900, the rising surface 13 becomes too rough, which may damage the finger 101 or nail 102. On the other hand, with abrasives of a grit higher than 1100, the tip becomes too slippery against the loose cuticle 104, making it difficult to lift the loose cuticle, and there is a risk of damaging the finger 101 (skin) if too much force is applied.
[0041] In contrast, the rising surface 13 was polished with abrasive material of JIS R6252 900 to 1100 grit. Polish If this is done, the rising surface 13 will not slip easily against the loose cuticle 104, and will make contact with the loose cuticle just enough to lift it up, thereby effectively removing the loose cuticle 104. In addition, because it makes contact with the loose cuticle just enough, the movement of the pusher 1 is suppressed, so contact between the preparation part 3 and the finger 101 (skin) can be avoided.
[0042] Next, the effects of the gel removal section 4 will be explained. Figure 19 is a conceptual cross-sectional view showing the layered structure of gel nails formed on a nail. For example, the gel nail 114 has a three-layer structure consisting of a base material 111, a color layer 112, and a top layer 113, in order from the surface side of the nail 102. Note that gel nails 114 have a multi-layer structure, and some have two or four or more layers.
[0043] To remove the gel nail 114 from the nail 102, first, the gel nail 114 is softened using a special solvent. Then, holding the shaft 2 of the pusher 1, the nail-facing surface 26 of the gel-removing part 4 is brought into contact with the nail 102, and the gel nail 114 is removed from the nail 102 by scraping off the base coat 111, color layer 112, and top layer 113 from the nail 102 with the tip 21 of the gel-removing part 4. At this time, although a detailed illustration is omitted, the corner 27 (see Figure 15) formed by the rising surface 23 and the nail-facing surface 26 contacts the tip of the gel nail 114 in a linear manner across its width.
[0044] Because the rising surface 23 is raised relative to the nail-facing surface 26, when the tip 21 of the gel removal part 4 is applied to the gel nail 114, the tip 21 of the gel removal part 4 is less likely to ride up on top of the gel nail 114, and the gel nail 114 is easier to lift up. In addition, since the lifted gel nail 114 makes contact with the rising surface 23 over its surface, it provides resistance to the movement of the pusher 1, and contact between the gel removal part 4 and the skin can be avoided.
[0045] Furthermore, the rising surface 23 was polished with abrasive material of JIS R6252 900 to 1100 grit. Polish If this is done, the raised surface 23 will not slip easily against the gel nail 114, and will make just enough contact with the gel nail 114 to lift it up, allowing for effective removal of the gel nail 114. In addition, because the pusher 1 makes just enough contact with the gel nail 114, its movement is suppressed, thus avoiding contact between the gel removal part 4 and the finger 101 (skin).
[0046] Needless to say, the embodiments described above do not limit the present invention. For example, the pusher 1 may be configured to include only the preparation section 3 or only the gel removal section 4. Alternatively, the pusher 1 may be configured to include at least one of the preparation section 3 and the gel removal section 4. Furthermore, in this embodiment, the nail-facing surface 14 and the nail-facing surface 26 were facing in the vertical direction, but they may be facing the same direction or at other angles.
