Description

flat eyelash curler

technical field

The invention relates to an eyelash curler as a beauty treatment tool, in particular to a flat eyelash curler.

Background technique

Many women currently use eyelash curlers on a daily or occasional basis for cosmetic purposes. Eyelash curlers are known that are configured to curl upwardly the natural eyelashes of the upper eyelid or to curl false eyelashes attached to the natural eyelashes together with the natural eyelashes. It is hoped that such an eyelash curling treatment can be performed not only at home, but also in various places and on the go. Therefore, various types of eyelash curlers are designed to be portable.

For example, KR20130003164 describes an eyelash curler that includes: a main body; a connector that is rotatably connected around the main body; a first eyebrow gripping portion that includes a first contact point; a second eyebrow gripping portion that is mounted on on one end of the main body; and a third eyebrow gripper mounted on the other end of the main body.

CN203314330 describes an eyelash curler comprising: a housing; a pulling member; a movable clamping member; and a spring acting on the movable clamping member. The pulling member is arranged on the housing in a pivoting mode, and the movable clamping member is assembled in the housing in a sliding mode. The housing is provided with a fixed clamp cooperating with an end portion of the movable clamp. The movable clamping part clamps the fixed clamping part under the action of the pulling part.

JP5324932 describes an eyelash curler comprising two gripping surfaces which can be moved towards and away from each other. The eyelashes can be clamped between these two clamping surfaces. The gripping surface is shaped to match the actual state of the lashes.

JP4559263 describes an eyelash curler comprising: a receiving member provided with a first pinch portion for pinching one side of the eyelashes; a sliding member provided with a second pinch portion for pinching the other side of the eyelashes a knob; and an operating member for moving the sliding member so that the sliding member can be pressed against the receiving member.

JP4473641 describes an eyelash curler comprising: an upper presser part for pressing the eyelashes from above; and a lower presser part for pressing the eyelashes from below. Each presser portion has a snap pressing portion. When the eyelash curler is used, an eyelid pad having a higher coefficient of friction than that of the upper presser part is mounted on at least a portion of the front face of the upper presser part in contact with the eyelid.

JP4226924 describes an eyelash curler comprising a pair of upper and lower pressing parts for pinching eyelashes. The paired pressing parts respectively have a plurality of protrusions extending in the longitudinal direction. These protrusions serve as pinches for pressing the eyelashes.

JP2001204535 describes an eyelash curler comprising: a body with an upper holding portion for holding eyelashes from above; and a sliding member with a lower holding portion for holding eyelashes from below. The sliding member is mounted to the body in a vertically slidable manner within a certain range of sliding movement. A guide for guiding the sliding member is interposed between the sliding member and the body. Guide means are not present at each end of the lower holding part, but below the lower holding part.

Such known eyelash curlers generally tend to be relatively bulky due to their complex structure, thus taking up a lot of space when carried, and therefore cannot be said to be easily portable. Further improvements are needed to make carrying the eyelash curler easier. In addition to being easy to carry, there is also a need to reduce the manufacturing cost of the eyelash curler by simplifying the structure of the eyelash curler.

Contents of the invention

The object of the present invention is to solve the above mentioned problems of existing eyelash curlers. More specifically, the object of the present invention is to provide a novel eyelash curler that is easy to carry, in other words, takes up little space when carried. In particular, the object of the present invention is to provide a novel eyelash curler which is easy to carry but has excellent maneuverability when used. Another object of the present invention is to provide a novel eyelash curler which is structurally simple and thus can be manufactured at low cost.

In order to achieve the above object, the present invention provides an eyelash curler for curling eyelashes, which comprises: a lower plate having a central axis, a proximal end and a distal end, wherein the lower plate comprises a a pair of lower ridges extending in a direction where the central axes of the plates intersect, wherein the lower plate further includes elastic pads for receiving eyelashes to be curled, the elastic pads being disposed in grooves defined between the lower ridges; and the upper plate , which has a central axis, a proximal end and a distal end, wherein the upper plate includes at the proximal end an upper ridge extending in a direction intersecting the central axis of the upper plate, wherein the upper ridge is configured to be able to cooperate with the elastic pad Pinching the eyelashes to be curled, wherein the lower plate and the upper plate are configured such that they can be combined with each other into a non-use position or a ready-to-use position, wherein, in the non-use position, the lower plate and the upper plate are combined with each other such that the upper plate In close contact with the lower plate, and the upper plate cannot pivot relative to the lower plate, and wherein, in the ready-to-use position, the lower plate and the upper plate are combined with each other so that the elastic pad and the upper ridge face each other, and the upper plate can be relatively The lower plate pivots for pinching the eyelashes to be curled between the resilient pad and the upper ridge.

In the present invention, the eyelashes to be curled by the eyelash curler may be natural eyelashes, tufted false eyelashes already attached or to be attached to natural eyelashes, or both natural eyelashes and tufted false eyelashes.

According to the present invention, when not used for cosmetic treatment, the lower plate and the upper plate of the eyelash curler may be combined with each other such that the upper plate and the lower plate are in close contact. In other words, in this non-use position, the eyelash curler according to the invention can take a flat form with minimal bulk, which requires only little space when carried. In this way, the ease of carrying or portability is significantly increased compared to conventional eyelash curlers which have a relatively large volume. On the other hand, when incorporated into a ready-to-use position, the eyelash curler according to the present invention can exhibit excellent operability for cosmetic treatments. That is to say, with the eyelash curler according to the present invention, eyelashes can be safely curled by a simple operation in which the eyelashes to be curled are clamped between the elastic pad of the lower plate and the upper ridge of the upper plate, and The upper plate then pivots relative to the lower plate. Apart from that, according to the invention, the eyelash curler essentially consists of only two plates, namely an upper plate and a lower plate. Therefore, the eyelash curler according to the present invention is structurally very simple and can therefore be manufactured at low cost compared to existing eyelash curlers.

According to a preferred aspect of the invention, the orientation of the upper panel relative to the lower panel in the non-use position may be opposite to the orientation of the upper panel relative to the lower panel in the ready-to-use position.

According to a preferred aspect of the invention, the lower plate may also comprise a slot at the proximal end, in particular if the orientation of the upper plate in the non-use position becomes opposite to the orientation of the upper plate in the ready-to-use position, the lower plate The upper ridge of the upper plate can enter the slot when the upper plate is engaged with each other in the non-use position. This aspect is particularly advantageous for flattening and compressing the eyelash curler in the non-use position.

According to a preferred aspect of the present invention, the lower plate may further comprise, at the distal end, an orifice extending in a direction orthogonal to the central axis of the lower plate. In this case, the distal end of the upper plate may have a width smaller than the width of the aperture of the lower plate. Furthermore, in this case, in the ready-to-use position, the lower plate and the upper plate can be joined to each other such that the distal end of the upper plate passes through the aperture of the lower plate. This preferred aspect advantageously provides a scissor mechanism which achieves excellent maneuverability during the crimping process. That is, according to this preferred aspect, the crimper can be handled as easily as, for example, a clothespin. According to a more preferred aspect of the present invention, in the ready-to-use position, the lower plate and the upper plate may contact each other along a straight line. In this case, the line along which the lower and upper plates contact each other in the ready-to-use position may define a virtual pivot axis about which the upper plate pivots relative to the lower plate.

According to a preferred aspect of the invention, the distal end of the upper plate may be offset from the main surface area of the upper plate in a direction perpendicular to the main surface area of the upper plate. In particular, the distal end of the upper plate may be offset in the same direction as the upper spine. Furthermore, if the distal end of the upper plate is offset, a portion of the lower plate distal to the aperture may be at least partially offset from the major surface area of the lower plate in a direction perpendicular to the major surface area of the lower plate. In particular, the portion of the lower plate may be offset in the opposite direction to the lower ridge. In addition, the hollow formed by offsetting this portion of the lower plate may be able to accommodate the offset distal end of the upper plate. This aspect is particularly advantageous if the orientation of the upper plate relative to the lower plate in the non-use position becomes opposite to the orientation of the upper plate relative to the lower plate in the ready-to-use position. This is because it realizes a non-use position in which unintentional separation of the lower plate and the lower plate does not easily occur (ie, a rigidly bonded state of the lower plate and the lower plate).

According to a preferred aspect of the present invention, a window may be formed in the lower plate, and a corresponding window may be formed in the upper plate. In this case, the window of the lower panel and the window of the upper panel may at least partially overlap each other, at least in the non-use position. Also, according to a more preferred aspect of the present invention, the window of the lower panel and the window of the upper panel may have different sizes and/or shapes from each other. According to this preferred aspect, the user can visually confirm the part of her face reflected in the mirror through one of the windows, especially the area around her eyes and her eyelashes. Not only that, but if the two windows have different sizes and/or shapes from each other, when separating the two panels, one panel can be pushed out with a fingertip through the window formed in the other panel. As a result, it is possible for the user to more easily transition from the non-use position to the ready-to-use position.

According to a preferred aspect of the invention, both the lower ridge of the lower plate and the upper ridge of the upper plate may be curved such that they are convex towards their distal ends. The curvature of the lower and upper ridges may eg follow a circle, an ellipse, a parabola, a hyperbola or any other curve. Furthermore, the lower and upper ridges may partially include straight portions.

According to a preferred aspect of the present invention, the eyelash curler may further include a locking mechanism. In this case, the locking mechanism may be configured to prevent inadvertent separation of the upper and lower panels when the lower and upper panels are coupled to each other in the non-use position. According to a more preferred aspect of the present invention, the locking mechanism may include at least one boss protruding from an inner peripheral surface of the slot of the lower plate into the slot (if the slot exists). In this case, the boss may be configured to retract when the upper ridge of the upper plate enters the slot to apply a pressing force to the upper ridge of the upper plate. This aspect also facilitates realization of a non-use position in which unintentional separation of the lower plate and the lower plate does not easily occur (ie, a rigidly bonded state of the lower plate and the lower plate).

According to a preferred aspect of the present invention, at least one of the upper plate and the lower plate may be made of non-metallic material selected from the group consisting of plastic material, wood material and bamboo material. In particular, at least one (more preferably both) of the upper and lower plates may be made of plastic material. Furthermore, according to a preferred aspect of the present invention, at least one (more preferably both) of the lower plate and the upper plate may be made of transparent or translucent plastic material. If both the lower and upper plates are made of a transparent plastic material, it is possible for the user to visually confirm through the plates the part of her face reflected in the mirror, especially the area around her eyes and her eyelashes .

Detailed ways

Some exemplary embodiments of the present invention will now be described with reference to FIGS. 1 to 13 . In each drawing, the scale ratio of width, length, height, diameter, etc. of each element may not be constant. It should be noted that in some of the drawings, certain elements or features are drawn larger or smaller than they actually are for emphasis.

As used herein, terms and directions such as "upper," "lower," "upper," "lower," "upward," "downward," "above," "below," "right," "left," etc. The relative terms should be read in conjunction with the orientation of the crimper in the drawings, which may or may not match the actual orientation in use. In addition, as apparent to those skilled in the art, in this specification, the term "distal side" means the side away from the eyelashes of the user when the user is curling the eyelashes with the curler. On the other hand, the term "proximal" means the side closer to the eyelashes of the user when the user is curling the eyelashes with the curler.

Figures 1 and 2 schematically show an eyelash curler 1 according to an embodiment of the invention for curling eyelashes indicated in some of the figures by reference "F". In particular, Figure 1 shows the eyelash curler 1 in a fully flat "non-use" position as described in detail below. Figure 2 schematically shows the same eyelash curler 1 in a "ready to use" position as described in detail below.

As can be seen from FIGS. 1 and 2 , the eyelash curler 1 includes a lower plate 10 and an upper plate 20 . In this embodiment, both the lower plate 10 and the upper plate 20 are made of plastic material, in particular transparent plastic material (except for the elastic pads described later). The lower plate 10 and the upper plate 20 may be formed, for example, by an injection molding process. The lower plate 10 and the upper plate 20 have both required flexibility and rigidity. For example, PCTA (polyethylene terephthalate), ABS (acrylonitrile butadiene styrene), PETG (polyethylene terephthalate copolymer), PP (polypropylene) can be used Acts on the plastic material forming the two panels 10 , 20 . However, in another embodiment, only one of the lower plate 10 and the upper plate 20 may be made of plastic material. Furthermore, in yet another embodiment, only one of the lower plate 10 and the upper plate 20 may be made of a transparent plastic material. Alternatively, one or both of the lower plate 10 and the upper plate 20 may be made of a translucent plastic material. One or both of the lower plate 10 and the upper plate 20 may be made of other non-metallic materials such as wood material and/or bamboo material.

As illustrated in FIGS. 3-5 , lower plate 10 has a central axis (ie, longitudinal axis) A ₁ , a proximal end 100a, a distal end 100b, and a major surface region 100c extending between proximal end 100a and distal end 100b. 3 to 5 show the lower plate 10 seen from various directions. That is, FIG. 3 is a perspective view of the lower plate 10 , FIG. 4 is a plan view of the lower plate 10 , and FIG. 5 is a cross-sectional view of the lower plate 10 taken along line X ₃ -X ₃ in FIG. 4 . As shown, the proximal end 100a of the lower plate 10 has a curved recess 102 that is convex towards the distal end 100b. The curvature of the recess 102 is appropriately selected according to the anatomical features of the face of the ethnicity in the region or zone where the product (eyelash curler) is provided. For example, the radius of curvature of a Caucasian eyelid contour typically has a smaller value than that of an Asian. This anatomical knowledge can be used to determine the curvature (radius of curvature) of the recess 102 .

Along the curved recess 102, the lower plate 10 includes a pair of lower ridges 110a, 110b at the proximal end 100a. These lower ridges 110 a , 110 b extend in a direction intersecting the central axis A ₁ of the lower plate 10 . The lower plate 10 also includes resilient pads 190 for receiving eyelashes to be curled in use. A pair of lower ridges 110a, 110b cooperate to define a groove 120 therebetween. The resilient pad 190 is disposed in the groove 120 defined between the lower ridges 110a, 110b. The resilient pad 190 extends in the groove 120 beyond the same extent as the lower ridges 110a, 110b. In this embodiment, the rounded upper end of the elastic pad 190 protrudes slightly from the opening of the groove 120 . Also, in this embodiment both the lower ridges 110a, 110b are curved, for example along a circular profile with a given radius of curvature (which may be variable), so that they are convex towards the distal end 100b. Also, in this embodiment, the resilient pad 190 is constructed of, for example, silicone rubber, but may be constructed using other suitable resilient materials.

On the other hand, as illustrated in FIGS. 6-8 , the upper plate 20 has a central axis (ie, a longitudinal axis) A ₂ , a proximal end 200 a, a distal end 200 b, and a main shaft extending between the proximal end 200 a and the distal end 200 b. Surface area 200c. 6 to 8 show the upper plate 20 viewed from various directions. That is, FIG. 6 is a perspective view of the upper plate 20 , FIG. 7 is a plan view of the upper plate 20 , and FIG. 8 is a cross-sectional view of the upper plate 20 taken along line X ₄ -X ₄ in FIG. 7 . As shown, the proximal end 200a of the upper plate 20 has a recess 202 that is convex toward the distal end 200b. The curvature of the recess 202 is also suitably selected as described above.

Along the curved recess 202, the upper plate 20 includes an upper ridge 210 at the proximal end 200a. The upper ridge 210 extends in a direction intersecting the central axis A ₂ of the upper plate 20 . As described in detail below, the upper ridge 210 is configured to co-operate with the elastic pad 190 of the lower plate 10 to pinch the eyelashes to be curled. In this embodiment, the upper ridge 210 is also curved corresponding to the curvature of the lower ridges 110a, 110b such that it is convex towards the distal end 200b.

The ridges 110a, 110b of the lower plate 10 and the ridges 210 of the upper plate 20 may have various cross-sections. In this embodiment, an elongated rectangle with rounded ends is employed as the cross-sectional shape of these ridges. However, the cross-sectional shape of the ridges may be trapezoidal (or inverted trapezoidal) or any other suitable shape.

Referring again to FIGS. 1 and 2 , the lower plate 10 and the upper plate 20 are configured such that they can be joined to each other in either a non-use position or a ready-to-use position. In particular, in this embodiment the orientation of the upper panel 20 relative to the lower panel 10 in the non-use position is opposite to the orientation of the upper panel 20 relative to the lower panel 10 in the ready-to-use position. As can also be seen from FIG. 9 (FIG. 9 is a sectional view of the eyelash curler 1 shown in FIG. 1 taken along line X ₁ -X ₁ in FIG. 1 ), in the non-use position, the lower plate 10 and The upper plates 20 are combined with each other such that the upper plate 20 is in close contact with the lower plate 10 . In this tight contact state, the upper plate 20 cannot pivot relative to the lower plate 10 . Therefore, the eyelash curler 1 shown in Figures 1 and 2 can be called a "flat eyelash curler".

On the other hand, in the ready-to-use position, the lower panel 10 and the upper panel 20 are combined with each other such that the elastic pad 190 and the upper ridge 210 face each other. In this combined state, the upper plate 20 can be used as a lever arm. That is, the upper plate 20 can pivot relative to the lower plate 10 to pinch the eyelashes to be curled between the elastic pads 190 and the upper ridges 210 (if desired or in some cases, by utilizing the appropriate elasticity of the upper plate 20). deformation). As can also be seen from FIG. 10 (FIG. 10 is a sectional view of the eyelash curler 1 shown in FIG. 2 taken along line _X2 - _X2 in FIG. 2), in the ready-to-use position, the lower plate 10 and the upper plate 20 are in contact with each other along a straight line. The lower plate 10 and the upper plate 20 define a virtual pivot axis B along their line of contact with each other in the ready-to-use position, about which the upper plate 20 pivots relative to the lower plate 10 .

Referring again to FIGS. 3-5 , the lower plate 10 also includes a slot 130 at its proximal end 100a. When the lower panel 10 and the upper panel 20 are coupled to each other in the non-use position, the upper ridge 210 of the upper panel 20 can enter into the slot 130 . Besides, the lower plate 10 also includes an orifice 140 extending in a direction orthogonal to the central axis A ₁ of the lower plate 10 at its distal end 100 b. The distal end 200b of the upper plate 20 has a width W ₂ that is less than the width W ₁ of the aperture 140 (see FIGS. 4 and 7 ). Thus, in the ready-to-use position, the lower plate 10 and the upper plate 20 are joined to each other such that the distal end 200b of the upper plate 20 passes through the aperture 140 of the lower plate 10 .

In this embodiment, the eyelash curler 1 also includes a locking mechanism. The locking mechanism is configured to prevent the upper panel 20 from being unintentionally separated from the lower panel 10 when the lower panel 10 and the upper panel 20 are coupled to each other in the non-use position. More specifically, the locking mechanism includes a boss 160 protruding from an inner peripheral surface of the slot 130 of the lower plate 10 into the slot 130 . As best shown in FIG. 4 , in the lower plate 10 behind the boss 160 , ie, between the boss 160 and the ridge 110 a , a slot 170 having a width slightly larger than that of the boss 160 is formed. Accordingly, when the upper ridge 210 of the upper plate 20 enters the slot 130, the boss 160 may retract slightly, as shown in FIG. 1 . In this retracted state, the boss 160 can apply a pressing force to the upper ridge 210 of the upper plate 20 . Although embodiments having a single boss have been described herein, those skilled in the art will appreciate that there may be multiple bosses.

As can be seen from FIG. 8 , the distal end 200b of the upper plate 20 is offset from the main surface area 200c of the upper plate 20 in a direction perpendicular to the main surface area 200c. Similarly, as can be seen from FIG. 5, a portion of the distal end 100b of the lower plate 10 located on the distal side of the aperture 140 is partially offset from the main surface area 100c of the lower plate 10 in a direction perpendicular to the main surface area 100c. shift. As mentioned above, in the non-use position, the orientation of the upper panel 20 relative to the lower panel 10 is opposite to the orientation of the upper panel 20 relative to the lower panel 10 in the ready-to-use position. Therefore, as shown in FIG. 9, in the flat non-use position, the distal end 200b of the upper plate 20 can fit snugly in the hollow formed by offsetting the portion of the distal end 100b of the lower plate 10. 180 (see Figures 3 to 5). This effectively prevents unintentional separation of the lower plate 10 and upper plate 20 , combined with an additional separation preventing effect brought about by the engagement between the upper ridge 210 and the slot 130 of the lower plate 10 .

Referring again to FIG. 4 , a window 150 is formed in the lower plate 10 . Similarly, as shown in FIG. 7 , a window 250 is formed in the upper plate 20 . The window 150 of the lower panel 10 and the window 250 of the upper panel 20 are configured to partially overlap each other in both the non-use position and the ready-to-use position. That is, the window 150 of the lower board 10 and the window 250 of the upper board 20 have different sizes and shapes from each other. In this embodiment, window 150 is a rectangle with one side curved (somewhat trapezoidal rectangle), and window 250 is a square with one side also curved (somewhat trapezoidal square). However, the windows 150, 250 may have any other shape. For example, polygonal shapes, semicircular shapes, circular shapes, oval shapes, etc. may be employed for the windows 150, 250 in addition to square and rectangular shapes. In another embodiment, the window may be provided on only one of the lower panel 10 and the upper panel 20 . In yet another embodiment, the two plates 10, 20 may not have any windows. By providing the window 250, the user can visually confirm the part of her face reflected in the mirror through the window 250, especially the area around her eyes and her eyelashes. Furthermore, since the two windows 150, 250 have different sizes and shapes from each other, the two plates 10, 20 can be easily separated when converting the eyelash curler 1 from the non-use position to the ready-to-use position. In order to do this, the user only needs to use her fingertips to push out a portion of the main surface 200c of the upper plate 20 (the portion with the grid pattern in FIG. 7 ), which is present in the window 150 in the lower plate 10 ( or visible from window 150).

However, the eyelashes to be curled may be false eyelashes in clusters attached to natural eyelashes or both natural and false eyelashes. For reference, false eyelashes typically include a plurality of discrete eyelash fibers and a baseline that links or connects the eyelash fibers to one another in substantially parallel fashion. Eyelash fibers can be synthetic or natural. For example, eyelash fibers can be silk fibers, cotton fibers, wool fibers, linen fibers, cellulose fibers, rayon fibers, polyamide

fiber, viscose fiber, acetate fiber, acrylic polymer fiber, polyolefin fiber, polyethylene terephthalate (PET) fiber, polybutylene terephthalate (PBT) fiber, glass fiber, Silica fiber, carbon fiber, polytetrafluoroethylene (such as />

Before being used for curling, the eyelash curler 1 is switched to the ready-to-use position. That is, the lower panel 10 and upper panel 20 are rejoined from the non-use position to the ready-to-use position. For this, first, the upper plate 20 is separated from the lower plate 10 (see FIG. 11( a )). This can be easily done, for example, by pushing the major surface area 200c of the upper plate 20 with a fingertip through the window 150 of the lower plate 10 . Subsequently, the upper plate 20 is again combined with the lower plate 10 in an orientation opposite to that in the non-use position. This can be easily done by first inverting the upper plate 20, and then inserting the distal end 200b of the inverted upper plate 20 into the aperture 140 of the lower plate 10 (see Figures 11(b) and 11(c)). As a result, the eyelash curler 1 is now in a ready-to-use position (see Figure 11(d)).

The curling process using the eyelash curler 1 switched from the non-use position to the ready-to-use position can be performed as follows. First, the user positions the eyelash curler 1 in front of the face so that the eyelashes F are located between the upper ridge 210 of the curler 1 and the elastic pad 190 (see Fig. 12(a)). Subsequently, the user pivots the upper plate 20 relative to the lower plate 10 by applying force from above and below to the upper plate 20 and the lower plate 10 with fingertips so that their proximal ends 100a, 200a approach each other. This causes the elastic pads 190 and upper ridges 210 to work together to curl the eyelashes F upward (see Figure 12(b)). In this state, the upper end of the elastic pad 190 is elastically collapsed by the upper ridge 210 and becomes concave. As mentioned above, the pivoting of the upper plate 20 may be accompanied by a moderate elastic deformation thereof.

Once the eyelashes F have been pressed, the user pivots the upper plate 20 in the opposite direction relative to the lower plate 10 so that their proximal ends 100a, 200a are spaced apart from each other (see Fig. 12(c)). This can be easily done by applying force with fingertips on the distal end 200b of the upper plate 20 and the distal end 100b of the lower plate 10 from above and below. The above process is usually repeated as many times as necessary, wherein the pinched position of the eyelashes F is slightly moved toward the tip of the eyelashes F. As a result, lashes F are now curled upward as a whole.

After the curling of the eyelashes F has been completed, the curler is converted into a completely flat, non-use position for portability or storage. That is, the lower panel 10 and the upper panel 20 are rejoined from the ready-to-use position to the non-use position. For this, the upper plate 20 is separated from the lower plate 10 again (see FIG. 13( a )). This can be easily done by pulling the distal end 200b of the upper plate 20 out of the aperture 140 of the lower plate 10 . Subsequently, the upper plate 20 is combined with the lower plate 10 again in an orientation opposite to that in the ready position. This can be easily done by first inverting the lower plate 10, and then reinserting the distal end 200b of the upper plate 20 into the aperture 140 of the inverted lower plate 10 (see Figures 13(b) and 13(c)). Finally, the upper ridge 210 of the upper plate 20 is inserted into the slot 130 of the lower plate 10 by overcoming the resistance of the aforementioned locking mechanism. As a result, the eyelash curler 1 is now in a completely flat, non-use position for easy portability (see Figure 13(d)).

As described above, when not used for cosmetic treatment, the lower plate 10 and the upper plate 20 of the eyelash curler 1 may be combined with each other such that the upper plate 20 is in close contact with the lower plate 10 . That is, in the non-use position, the eyelash curler 1 can assume a completely flat form with minimal bulk, which requires only little space to carry and store. Therefore, the convenience of carrying or portability is significantly increased compared with conventional eyelash curlers having a relatively large volume. On the other hand, when incorporated into the ready-to-use position, the eyelash curler 1 exhibits excellent operability for cosmetic treatments. That is, with the eyelash curler 1, the eyelashes F can be curled by the simple operation of clamping the eyelashes F to be curled between the elastic pad 190 and the upper ridge 210 and then pivoting the upper plate 20 relative to the lower plate 10. Curl it securely. In addition, since the eyelash curler 1 basically consists of only two plates (i.e. the lower plate 10 and the upper plate 20 ), obtained for example by an injection process, the eyelash curler 1 is structurally simple and therefore compatible with existing eyelash curlers. device can be manufactured at low cost.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to these embodiments, and various modifications and changes can be made to the above-described embodiments without departing from the scope of the present invention, and such modifications and changes are also included in the scope of the present invention.
