Description

Technical Field

[0001] The present invention relates to a rod for eyelash permanent curl.

Background Art

[0002] Eyelashes grow from the thin eyelid in 2 to 3 rows with a thickness of about 1 mm. Since eyelashes clarify the contour of the eyes, when there are many and thick eyelashes or their length is long, they may look more beautiful.

[0003] When applying makeup, it is effective to curl the eyelashes upward so that the eyes look larger. For this purpose, a curler is used to curl the eyelashes upward, or a method of attaching curled artificial eyelashes is used.

[0004] A curler temporarily creates an upward curl on the eyelashes and returns to the original state as time passes, which is troublesome as it needs to be adjusted several times a day. Artificial eyelashes are relatively expensive and fall off as time passes.

[0005] Therefore, a perm that creates a permanent curl for hair has also been applied to eyelashes.

[0006] FIG. 8 is a drawing showing a rod for eyelash perm of Japanese Patent Application Laid-Open No. JP2002058523A, schematically showing a state of performing an eyelash perm. The rod 11 for eyelash perm is composed of a plate-shaped base 13 and a rod portion 14 formed at one end of the base portion 13. The base 13 is fixed above the eyes with double-sided tape. After the eyelashes 12 cross the rod portion 14 and the tip side of the eyelashes 12 is adhered to the eyelash fixing surface 15, a perm solution is applied to the eyelashes 12 to perform a permanent curl.

[0007] One shape of curl can be created depending on the cylindrical size of the rod portion 14.

Summary of the Invention

Problems to be Solved by the Invention

[0009] An object of the present invention is to provide an eyelash perm rod that can group a plurality of eyelashes at the same interval to create curls and can select the angle of the eyelash curls.

Means for Solving the Problems

[0010] To achieve the above object, the present invention provides a base formed in a plate shape having a length corresponding to the width of the eye and a width corresponding to the length of the eyelashes, and having an upper surface curved and convex; and

[0011] a plurality of guide convex portions arranged in parallel at set intervals on the upper surface of the base in a comb shape perpendicular to the length direction of the base; and the base provides an eyelash perm rod characterized in that a cross section perpendicular to the length direction is formed in a semi-elliptical shape.

[0012] The base is characterized in that a cross section perpendicular to the length direction is formed in a semi-elliptical shape, but the curvatures of one horizontal plane and the other horizontal plane are different.

[0013] The base is flat such that the bottom surface has a plate shape, but is formed to be concave from the edge towards the center, and is formed to be concave such that the depth of the most concave region is 1 mm or less.

[0014] The guide convex portion is formed such that both ends are gathered into a tapered end shape.

[0015] The guide convex portion is formed such that, in the interval between adjacent guide convex portions, the interval between the ends is twice the interval between the regions that are not the ends.

Advantages of the Invention

[0016] According to the embodiment of the present invention configured as described above, it is possible to select from among two types of curls with a single rod, group adjacent eyelashes at a set interval, gather the ends of the grouped eyelashes to create a curl, and provide an eyelash perm rod that can give the effect of making the eyelashes look clearer.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below.

[0019] Also, throughout the specification, stating that a certain component "includes" means that, unless otherwise stated to the contrary, it does not exclude other components and can further include other components.

[0020] FIG. 1 is a drawing showing an eyelash perm rod according to an embodiment of the present invention, FIGS. 2 and 3 are photographs for explaining the eyelash perm rod according to an embodiment of the present invention, FIG. 4 is a drawing showing a cross-section of the eyelash perm rod according to an embodiment of the present invention, FIG. 5 is a drawing showing the bottom surface of the eyelash perm rod according to an embodiment of the present invention, FIG. 6 is a drawing showing the usage state of the eyelash perm rod according to an embodiment of the present invention, and FIG. 7 is a drawing showing the result of using the eyelash perm rod according to an embodiment of the present invention.

[0021] As shown in the figure, the eyelash perm rod according to an embodiment of the present invention is composed of a plate-shaped base 110 having a length corresponding to the length of the eyes and a plurality of guide protrusions 120 formed on the upper surface of the base 110. The base 110 and the guide protrusions 120 are preferably integrally formed of a silicon material.

[0022] The base 110 has an arcuately rounded upper surface and a flat bottom surface 111. As shown in FIG. 4, the base 110 is formed such that its cross-section is semi-elliptical. When the longer side is the horizontal side, it is preferable that the elliptical curvatures of one horizontal plane and the other horizontal plane are different. When the elliptical curvatures are different, the angle between the bottom surface 111 and the upper surface is different, and the smaller the angle, the more the curl is formed to bend further upward from the root side of the curl. That is, the r b side in FIG. 4 with a smaller curvature a has a smaller curvature than the r b side. When arranging it so that the r a side is located on the root side of the eyelash and performing an eyelash perm, a curl is formed closer to the eyelid side than when arranging it so that the r a side is located on the root side of the eyelash and performing an eyelash perm. The r b side has a larger curvature than the r

[0023] side, so a soft round curl is formed. Also, the base 110 is rounded so that its thickness becomes thinner toward both ends in the length direction. The bottom surface 111 of the base 110 is flat and has a plate-like shape, but is recessed in the center with a size of 1 mm or less. During use, the bottom surface 111 is placed on the eyelid, but a substance with stickiness like glue can be applied to the bottom surface 111 and it can be made to adhere to the eyelid. The bottom surface 111 of the base has a thin protruding edge and is recessed from the edge toward the center, but is recessed so that the depth of the most recessed area is 1 mm or less. When the bottom surface is recessed, the adsorption force due to vacuum can be exerted when adhering to the eyelid. The base 110 can be fixed on the eyelid without a separate adhesive.

[0024] The guide protrusions 120 are formed in a rod shape perpendicular to the length direction and a plurality of them are arranged in parallel at intervals of 1 mm. The guide protrusions 120 are formed such that the end portions 121 are gathered in a conical shape. Since the end portions 121 of the guide protrusions 120 are gathered in a conical shape, the main region 122 is formed in a rod shape with a thickness of 1 mm, and when a plurality of guide protrusions 120 are spaced apart and arranged in parallel such that the interval w2 of the main region 122 is 1 mm, the interval w1 between the end portions 121 becomes at most 2 mm. If eyelashes with perm solution applied are arranged in the grooves between the guide protrusions 120, a plurality of eyelashes between w1 are inserted into one groove. Since the interval becomes narrower toward the w2 side, a plurality of adjacent eyelashes become perm-shaped such that their tips are gathered. When a plurality of adjacent eyelashes become perm-shaped with their tips gathered together as in the following photograph of FIG. 7, since the plurality of adjacent eyelashes are gathered together, there is an effect that the eyelashes look clearer.
