Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional eyelash curler, since the length in the width direction of the upper pressing portion is long with respect to the eye width, it is difficult to control the position of the eyelashes to be pinched, and it is difficult to raise the targeted eyelashes.

[0005] In addition, in the conventional eyelash curler, since it has a loose R shape with respect to the surface curvature of the eyelid, there is a problem that it is particularly likely to miss raising the eyelashes at the inner corner and outer corner of the eye.

[0006] Furthermore, in the conventional eyelash curler, when pressing against the eyelid, the central portion comes into contact, local pressure is applied, and there is a problem that the feeling of use is poor.

[0007] Therefore, the present disclosure has been made in view of the above problems, and an object thereof is to provide an eyelash curler that can efficiently and easily raise targeted eyelashes and has little discomfort when contacting the skin.

Means for Solving the Problems

[0008] The first feature of this disclosure is an eyelash curler comprising a main body having an upper pressing portion for pressing eyelashes from above, and a sliding member having a lower pressing portion for pressing eyelashes from below, wherein the sliding member is attached to the main body so as to be able to slide up and down within a certain range, and in a front view, the radius of curvature of the central part of the width direction of the upper pressing portion is in the range of 30 to 45 mm, and in a plan view, the radius of curvature of the central part of the width direction of the upper pressing portion is in the range of 15 to 25 mm, and the angle between the vertical direction and the extension direction of the upper pressing portion is 5° to 2° The gist of the invention is that the angle is within 0°, in the front view the length in the width direction is within the range of 25 to 40 mm, in the plan view the length in the thickness direction is within the range of 12 to 18 mm, in the front view the length in the longitudinal direction is within the range of 40 to 55 mm, a recess is formed on the front side of the main body, in the front view the length in the width direction of the recess is within the range of 16 to 24 mm, the length in the longitudinal direction of the recess is within the range of 18 to 25 mm, and in the plan view the length in the thickness direction of the recess is within the range of 0.5 to 1.0 mm.

In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of dimensions, etc., may differ from those of reality. Therefore, specific dimensions, etc., should be determined by referring to the following description.

In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustration.

[0012] (First Embodiment) The eyelash curler 100 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 4.

[0013] Figure 1 is an example of a front view of the eyelash curler 100 according to this embodiment, Figure 2 is an example of a top view of the eyelash curler 100 according to this embodiment, Figure 3 is an example of a right side view of the eyelash curler 100 according to this embodiment, and Figure 4 is an example of an enlarged view of the area around the upper pressing part 1 of the eyelash curler according to this embodiment.

[0014] As shown in Figures 1 to 3, the eyelash curler 100 according to this embodiment comprises a main body 2 and a sliding member 4.

[0015] For example, the main body 2 is made of plastic and is formed by joining the front part 2F and the rear part 2B of the main body together, as shown in Figures 2 and 3.

[0016] As shown in Figures 1 to 3, the main body 2 has an upper pressing portion 1 for pressing the eyelashes from above. Specifically, the rear portion 2B of the main body extends upward above the front portion 2F of the main body, and the upper pressing portion 1 is formed at the upper end of the rear portion 2B of the main body.

[0017] For example, the sliding member 4 is a thick plate-shaped member integrally formed of plastic. As shown in FIGS. 1 to 3, the sliding member 4 has a pressing portion 3 for pressing the eyelashes from below. Specifically, the pressing portion 3 is formed at the upper end of the body portion 4A of the sliding member 4. For example, the pressing portion 3 is formed by attaching an elongated rubber to the upper end of the body portion 4A of the sliding member 4.

[0018] The sliding member 4 is attached to the main body 2 so as to be slidable within a certain range in the vertical direction. Specifically, the body portion 4A of the sliding member 4 is installed inside a cavity portion (not shown) provided inside the main body 2, and the sliding member 4 is configured to slide within a certain range in the vertical direction. For example, the sliding member 4 may be configured to slide within a certain range in the vertical direction by a coil spring or the like.

[0019] Note that any regulating means can be used as a means for regulating the sliding range (certain range) of the sliding member 4.

[0020] Here, when the sliding member 4 slides upward, the pressing portion 3 of the sliding member 4 can press against the upper pressing portion 1 to curl the eyelashes.

[0021] As shown in FIG. 1, in a front view, the radius of curvature r1 at the central portion in the width direction W of the upper pressing portion 1 is within the range of 30 to 45 mm.

[0022] Also, as shown in FIG. 2, in a plan view, the radius of curvature r2 at the central portion in the width direction W of the upper pressing portion 1 is within the range of 15 to 25 mm.

[0023] Furthermore, as shown in FIG. 3, the angle α formed by the vertical direction and the extending direction D1 of the upper pressing portion 1 is within the range of 5° to 20°.

[0024] The eyelash curler 100 having the above-described configuration has a shape with a radius of curvature r1 that provides a good feeling of use with respect to the arch where the eyelashes grow when viewed from the front of a Japanese adult female.

[0025] Furthermore, the eyelash curler 100 having the above configuration has a shape with a radius of curvature r2 of the upper pressing portion 1 that matches the arch of the eyelid surface of an adult Japanese woman.

[0026] Furthermore, in the eyelash curler 100 having the above configuration, the tip portion 1E of the upper pressing portion 1 has a rib-like projection having the angle α described above. This projection functions as a pivot point for the rotational movement of the curler when lifting the eyelashes, and this angle α is suitable for the initial movement of lifting the eyelashes.

[0027] The inventors created prototypes of several types of eyelash curlers and conducted usage tests on adult women. As a result, they discovered that when the radius of curvature r1 at the center of the width direction W of the upper pressing part 1 in a front view and the radius of curvature r2 at the center of the width direction W of the upper pressing part 1 in a plan view are set to the above range, the device fits the curved shape of the eyelash base of adult women more easily and makes it easier to curl the eyelashes.

[0028] Furthermore, as a result of conducting such usage tests, the inventors discovered that when the angle α is set to 5° to 20°, the user's fingers do not get in the way when using the device, allowing the user to apply the upper pressing part 1 to the eyelid at an appropriate angle, making it easier to curl the eyelashes.

[0029] On the other hand, the inventors discovered that when the radii of curvature r1 and r2 are outside the above-mentioned range, the shape does not fit the base of the eyelashes.

[0030] Furthermore, the inventors discovered that when the angle α is less than 5°, the user's fingers get in the way during use, and when the angle α is greater than 20°, the user has to raise their hand to operate it, which tends to make it unstable.

[0031] Here, as shown in Figure 3, it is preferable that the radius of curvature r5 of such projection is within the range of 0.1 to 1.0 mm. From the results of the above-mentioned usage tests, the inventors discovered that when the radius of curvature r5 is within the above range, it is easy to press against the eyelid and does not cause pain to the eyelid.

[0032] Furthermore, as shown in Figure 1, in a front view, the radius of curvature r3 at the central part of the width direction W of the upper pressing portion 1 is preferably within the range of 30 to 45 mm.

[0033] Based on the results of the above-mentioned usage tests, the inventors discovered that when the radius of curvature r3 at the central part of the width direction W of the upper pressing portion 1 in a front view is set within the range of 30 to 45 mm, the pressure applied to the eyelid is distributed and discomfort is suppressed when rotating the eyelash curler 100 with the upper end of the upper pressing portion 1 as the pivot point, allowing for comfortable use. On the other hand, the inventors found from the results of the above-mentioned usage tests that when the radius of curvature r3 is less than 30 mm, the pressure on the eyelids increases, making it likely that the user will feel uncomfortable. They also found that when the radius of curvature r3 is greater than 45 mm, it becomes difficult to lift the eyelids, which may make it difficult to curl the eyelashes.

[0034] Furthermore, as shown in Figure 1, in a front view, it is preferable that the radius of curvature r4 at both ends of the upper pressing portion 1 in the width direction W is within the range of 15 to 25 mm.

[0035] Based on the results of the above-mentioned usage tests, the inventors discovered that when the radius of curvature r4 at both ends of the width direction W of the upper pressing portion 1 in a front view is set within the range of 15 to 25 mm, the main body is prevented from touching the bridge of the nose (between the eyes), making the eyelash curler easier to use.

[0036] Furthermore, as shown in Figure 1, in a front view, the length W1 in the width direction W is preferably in the range of 25 to 40 mm; as shown in Figure 2, in a plan view, the length T1 in the thickness direction T is preferably in the range of 12 to 18 mm; and as shown in Figure 1, in a front view, the length L1 in the longitudinal direction L is preferably in the range of 40 to 55 mm.

[0037] Here, as shown in Figure 2, in a plan view, it is preferable that the length T2 in the thickness direction T of the upper pressing portion 1 and the lower pressing portion 3 is within the range of 8 to 14 mm.

[0038] This configuration allows for an unprecedentedly compact eyelash curler 100, making it easy to carry around, for example, in a pouch, and convenient for curling eyelashes anywhere.

[0039] From the results of the above-mentioned usage tests, the inventors discovered that if the length T2 is made larger than 14 mm, the device becomes too large and cumbersome, making it difficult to carry around, and that if the length T2 is made smaller than 8 mm, it may become too small and difficult to operate.

[0040] Furthermore, as shown in Figure 1, a recess 2A is formed on the front side of the main body 1. As shown in Figure 1, in a front view, the length W2 in the width direction W of the recess 2A is in the range of 16 to 24 mm, and the length L2 in the longitudinal direction L of the recess 2A is in the range of 18 to 25 mm. Also, as shown in Figure 2, the length T3 in the thickness direction T of the recess 2A is in the range of 0.5 to 1.0 mm.

[0041] With this configuration, by setting the size of the recess 2A to the range described above, the user's thumb can be placed on the recess 2A, resulting in an eyelash curler 100 that is more compact than conventional models and easier to use.

[0042] Furthermore, as shown in Figure 4, it is preferable that the upper pressing portion 1 has a shape in which its thickness decreases towards the tip portion 1E, and that a recess 1A is formed on the back side of the upper pressing portion 1.

[0043] With this configuration, when the upper pressing part 1 is pressed against the eyelid, it easily bites into the skin, making it easier to lift the eyelid and curl the eyelashes. As a result, even with its compact size, it is possible to curl the eyelashes firmly.

[0044] The eyelash curler 100 according to this embodiment may have a structure similar to that of the above-mentioned Patent Document 1, that is, a structure in which a sliding member 4 is moved up and down by operating a lever (not shown). In such a case, when curling eyelashes, the user is configured to rotate the lever downward, as shown in Figure 6 of Patent Document 1.

[0045] Typically, users operate the eyelash curler with one hand. When using the eyelash curler described in Patent Document 1, the user places their thumb on the front side of the eyelash curler and their index finger, or index finger and middle finger, on the outer surface of the lever to operate it.

[0046] In the case of the eyelash curler described in Patent Document 1, since it lacks the recess 2A provided in the eyelash curler 100 according to this embodiment, the eyelash curler may slip out upwards, potentially causing problems during use. On the other hand, the eyelash curler 100 according to this embodiment is provided with a recess 2A, so that a part of the user's thumb pad can touch the lower end of the recess 2A, preventing the eyelash curler 100 from slipping out upwards and allowing for comfortable use.

[0047] Here, in order to maintain the strength of the main body 2 of the eyelash curler 100, a certain wall thickness is required, and if the depth of the recess 2A is increased, the thickness of the main body 2 of the eyelash curler 100 will also increase. Therefore, by keeping the thickness (depth) (length T3 in the thickness direction) of the recess 2A of the eyelash curler 100 within the above range, both compactness and comfort during use can be achieved.

[0048] Although the present invention has been described in detail using the embodiments described above, it will be clear 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 herein is for illustrative purposes only and is not intended to be restrictive in any way to the present invention. [Industrial applicability]

[0049] Furthermore, according to this embodiment, the minimum necessary width and curvature radius r1~r4 that fits the surface of the eyelid make it easy to curl the targeted eyelashes, allowing you to curl the eyelashes in the fewest number of strokes and reducing the workload. In addition, according to this embodiment, there is less discomfort when it comes into contact with the skin. As a result, this embodiment has a structure that makes it easy to curl eyelashes, and its compact and portable size makes it easy for anyone to curl their eyelashes anywhere, thus contributing to SDG Goal 10, "Reduce inequalities within and among countries."
