Description

Artificial nail and transfer kit for artificial nail

Technical Field

The present disclosure relates to an artificial nail and a transfer set for an artificial nail, and more particularly, to an artificial nail having a design layer having a plurality of die cut lines and attached to a nail body having a three-dimensional curve and a transfer set for an artificial nail.

Background

A user attaches artificial nails having various designs to her nails to change the length or shape of the nails.

Generally, a design layer attached to a nail body of an artificial nail is formed of a film of a rigid material and has a flat shape, and thus wrinkles occur in the design layer when the design layer is attached to the nail body having a three-dimensional curve.

Therefore, in order to solve the above-described problems, conventionally, an operation of removing wrinkles is performed after attaching a design layer to a nail body.

However, since the user must manually remove the wrinkles occurring in the design layer, it takes a long operation time for a novice hand having low performance of operation to remove the wrinkles, and the production cost of the artificial nail is increased. In addition, the design layer may be contaminated by impurities during the removal of the wrinkles.

Accordingly, there is a need for a method of preventing wrinkles from occurring when attaching a design layer to a nail body.

Referring to fig. 1 to 3, a transfer set 100 for an artificial nail according to the present disclosure includes a sticker 110 and

transfer bodies

130, 130a, wherein the sticker 110 has a design layer 117, a base layer 115 disposed on a lower surface of the design layer 117, and an adhesive layer 113 disposed on a lower surface of the base layer 115 and releasably adhered to a release sheet 111, the

transfer bodies

130, 130a integrally peel off the design layer 117, the base layer 115, and the adhesive layer 113 adhered to the sticker 110, and attach the peeled design layer 117, base layer 115, and adhesive layer 113 to a nail body M of an artificial nail 200. In addition, the base layer 115 according to the present embodiment may be disposed on an upper layer of the design layer 117.

The transfer set 100 for an artificial nail according to the present embodiment integrally adheres the design layer 117, the base layer 115, and the adhesive layer 113 to the

transfer body

130, 130a, transfers the

transfer body

130, 130a over the nail body M, and presses the design layer 117, the base layer 115, and the adhesive layer 113 onto the nail body M via contact, so that the design layer 117, the base layer 115, and the adhesive layer 113 can be easily attached to the nail body M using the

transfer body

130, 130 a.

Referring to fig. 3, the sticker 110 according to the present embodiment has an adhesive layer 113 releasably adhered to an upper surface of a release sheet 111, and a base layer 115 and a design layer 117 or a design layer 117 and a base layer 115 sequentially stacked on an upper surface of the adhesive layer 113.

The release sheet 111 may be manufactured by surface-coating a film or sheet made of one selected from paper, polyvinyl chloride (PVC), Polyethylene (PE), Polyurethane (PU), polypropylene (PP), polyethylene terephthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA), and acrylic resin or a polymer thereof with silicone, teflon, and fluorine.

The adhesive layer 113, the base layer 115, and the design layer 117, or the adhesive layer 113, the design layer 117, and the base layer 115 are sequentially stacked on the upper surface of the release sheet 111. In addition, the adhesive layer 113, the base layer 115, and the design layer 117 are integrally peeled off from the release sheet 111.

In this embodiment, the surface tension of the release sheet 111 is 36dyne/cm or less per unit width to easily peel the adhesive layer 113 from the release sheet 111 and prevent a tear and pop-up phenomenon (pop-up phenomena) of the release sheet 111.

The adhesive layer 113 preferably has a viscosity of 300 to 25000 gf/in. Viscosity measurements may be made according to the ASTM D3330180 degree peel test.

For example, when the adhesive layer 113 on which the base layer 115 and the design layer 117 are stacked is attached to the nail body M of the artificial nail 200, in the case where the viscosity of the adhesive layer 113 is less than 300gf/in, the adhesive layer 113 is spaced apart from the nail body M and is likely to be separated from the nail body M; in the case where the viscosity of the adhesive layer 113 exceeds 25000gf/in, when the user separates the adhesive layer 113 from the nail body M for replacement purposes, the nail body M may be damaged.

Therefore, the viscosity of the adhesive layer 113 is preferably 300 to 25000 gf/in.

In this embodiment, the base layer 115 may be stacked on the upper surface of the adhesive layer 113, as shown in fig. 3(a) and 3(b), or on the upper surface of the design layer 117, as shown in fig. 3(c) and 3 (d).

The base layer 115 may be a film or sheet made of one selected from the group consisting of: polyvinyl chloride (PVC), Polyethylene (PE), Polyurethane (PU), polypropylene (PP), polyethylene terephthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA), and acrylic resin or a polymer thereof.

In addition, although not shown, the color ink may be printed on the upper surface or the lower surface of the base layer 115 by one selected from a screen printing method, a photolithography method, and a gravure printing method.

In this case, the entire upper or lower surface of the base layer 115 may be printed in one color, but is not limited thereto, and the entire upper or lower surface of the base layer 115 may be divided into a plurality of regions, and each region may be repeatedly printed in a different color or a predetermined color.

In the case where design layer 117 is formed of a transparent holographic film as described below, the colors printed on base layer 115 may achieve a more unique color reproduction by being projected on the transparent holographic film.

In addition, although not shown, metal thin films of aluminum (Al), nickel (Ni), and chromium (Cr) may be deposited on the upper and lower surfaces of the base layer 115. Depending on the stack thickness, the metal film can be produced transparently or opaquely. The metal thin film deposited on the base layer 115 can provide various metallic senses and holographic effects.

In the present embodiment, the design layer 117 may be a transparent or opaque film or sheet stacked on the upper surface of the base layer 115 or between the base layer 115 and the adhesive layer 113.

Meanwhile, the design layer 117 may include a transparent holographic film having various holographic patterns and designs formed on one surface of the base film. Holographic films change color or design depending on the viewing direction.

In addition, the base film used in the transparent hologram film may be made of a polymer resin that is the same as or similar to the material of the base layer 115 described above.

Meanwhile, the design layer 117 formed of the transparent holographic film or sheet has a rigid material, and thus wrinkles may occur in the design layer 117, especially when the design layer 117 is attached to the nail body M having a three-dimensional (3D) curve.

Therefore, in the present embodiment, a plurality of first die cut lines 118 are formed in the design layer 117 to prevent wrinkles from occurring in the design layer 117 when the design layer 117 is attached to the nail body M. That is, when the flat-shaped design layer 117 is attached to the nail body M having the 3D curve, wrinkles may occur in the design layer 117 due to a curvature radius of the nail body M, and the wrinkles may be prevented by adjusting the length, shape, and interval of the first die cut line 118 formed in the design layer 117.

Specifically, as shown in fig. 4, the design layer 117 includes a plurality of unit design layers 117a which are separated by a plurality of first die cut lines 118 and adhered to the nail body M by the medium of the adhesive layer 113. That is, the design layer 117 is divided into a plurality of unit design layers 117a by a plurality of first mold cuts 118.

In addition, one side end of the first die cut line 118 cuts the outer surface of the design layer 117. In addition, the other side end of the first die cut line 118 arranged in the length direction (y direction) of the design layer 117 cuts the design layer 117 inward by at least 5% of the length of the design layer 117 from the outer surface of the length direction (y direction) of the design layer 117; and the other side end of the first die cut line 118 arranged in the width direction (X direction) of the design layer 117 cuts the design layer 117 inward by at least 5% of the width of the design layer 117 from the outer surface of the design layer 117 in the width direction (X direction). In this case, when the other side ends of the first die cut lines 118 arranged on both sides of the design layer 117 in the length direction (y direction) and the width direction (x direction) are 50% of the length and width of the design layer 117, the first die cut lines 118 cut through the design layer 117, as shown in fig. 4(b) and 4 (c).

In addition, the total length of the first die cut lines 118 formed in the design layer 117 is preferably 3 to 500% of the length of the outer surface of the design layer 117, and the total area of the first die cut lines 118 is preferably 0.5 to 25% of the surface area of the design layer 117. Here, the total area of the first die cut lines is the sum of products of the width and the length of the first die cut line 118 formed in the design layer 117.

When the total length of the first die cut line 118 is less than 3% and the total area of the first die cut line is less than 0.5%, wrinkles may occur in the design layer 117, and when the total length of the first die cut line 118 exceeds 500% and the total area of the first die cut line exceeds 25%, the stiffness of the design layer 117 itself may be reduced.

Specifically, as shown in fig. 4(a), 4(b) and 4(c), the plurality of first die cut lines 118 may include a plurality of straight die cut lines c1 having a predetermined width formed in the design layer 117. In fig. 4(a) and 4(b), the first die cut lines 118 intersect in the length direction (y direction) and the width direction (x direction) of the design layer 117, and in fig. 4(c), the first die cut lines 118 intersect in the diagonal direction.

In addition, as shown in fig. 4(d), the plurality of first die cut lines 118 according to another embodiment may include a plurality of tapered die cut lines c2 formed in the design layer 117, the plurality of tapered die cut lines c2 having increasing or decreasing widths inward from the outer surface of the design layer. In addition, as shown in fig. 4(e), the plurality of first die cut lines 118 according to still another embodiment may include a plurality of straight die cut lines c1 formed in the design layer 117 and a plurality of tapered die cut lines c2 formed in the design layer 117.

Meanwhile, as shown in fig. 4(a), 4(d) and 4(e), the design layer 117 may further include a connection part 119 formed between the first die cut lines 118 to prevent separation of the plurality of unit design layers 117 a.

When the design layer 117 is divided into a plurality of unit design layers 117a by the plurality of first die cuts 118, the connection portion 119 is provided to prevent the unit design layer 117a from being divided into blocks by the plurality of first die cuts 118. That is, in order to prevent the design layer 117 from being divided into pieces by two first die cut lines 118 connected to each other or one first die cut line 118 passing through the design layer 117 from one side to the other side, in the present embodiment, the connection portion 119 is disposed between the first die cut lines 118.

In addition, as shown in fig. 4(f), the plurality of first die tangents 118 according to still another embodiment includes a straight die tangent c1 and a tapered die tangent c2 to divide the design layer 117 into a plurality of unit design layers 117 a. In this case, the base layer 115 and the adhesive layer 113 may be disposed on the lower surface of each of the separated unit design layers 117 a.

In addition, as shown in fig. 4(g), the plurality of first die cut lines 118 according to still another embodiment may include a bending die cut line c3 having a predetermined width in the design layer 117. In this case, the design layer 117 may be divided into a plurality of unit design layers 117a by the bent die-cut lines c3, or the design layer 117 may have a connection portion (not shown) between the bent die-cut lines c3 to prevent the separation of the plurality of unit design layers 117 a.

Meanwhile, although fig. 4(a) to 4(g) illustrate the first die cut line 118 formed in the design layer 117 according to the present embodiment, the scope of the present disclosure is not limited thereto.

Meanwhile, when the base layer 115 is interposed between the design layer 117 and the adhesive layer 113 as shown in fig. 3(a), and when the base layer 115 is stacked on the upper surface of the design layer 117 as shown in fig. 3(c), a plurality of second mold cuts 116 may be formed in the base layer 115 at positions corresponding to a plurality of first mold cuts 118 formed in the design layer 117.

The base layer 115 also has a rigid material, and thus when the base layer 115 is attached to the nail body M having a 3D curve, wrinkles may occur in the base layer 115, and thus a plurality of second mold cuts 116 are formed in the base layer 115 at positions corresponding to the first mold cuts 118.

In addition, as shown in fig. 3(b) and 3(d), a plurality of third die cut lines 114 may be formed in the adhesive layer 113 at positions corresponding to the plurality of first die cut lines 118 formed in the design layer 117 and the plurality of second die cut lines 116 formed in the base layer 115.

In the case where a double-sided tape is used for the adhesive layer 113, wrinkles may also occur when the double-sided tape is attached to the nail body M having a 3D curve, and thus a plurality of third die cut lines 114 may be formed in the adhesive layer 113 at positions corresponding to the first die cut line 118 and the second die cut line 116.

The

transfer bodies

130, 130a according to the present embodiment play a role in easily peeling the design layer 117, the base layer 115, and the adhesive layer 113 adhered to the release sheet 111 from the release sheet 111 as a whole and attaching to the nail main body M.

As shown in fig. 1, the transfer body 130 according to the embodiment includes a body portion 131, a pressing portion 133 extending and bent from the body portion 131, and an adhesive portion 135 attached to a lower surface of the pressing portion 133.

The body portion 131 may be formed in the shape of a long rod to allow a user to grip, but the scope of the present disclosure is not limited thereto, and any shape that a user can grip may be used.

Further, the pressing part 133 extends and bends from one or both ends of the body part 131, and may be formed in a flat shape allowing a user to press the upper surface with a finger.

Further, the pressing part 133 may be formed in a curved shape having a predetermined radius of curvature. As shown in fig. 5(a), when the pressing part 133 is formed in a curved shape, a width-direction curvature radius R1 of the pressing part 133 may be 10 to 360mm when viewed from a direction a of fig. 1, and as shown in fig. 5(B), a length-direction curvature radius R2 of the pressing part 133 may be 30 to 400mm when viewed from a direction B of fig. 1.

In addition, the adhesive portion 135 is detachably attached to the lower surface of the pressing portion 133 as described below.

In addition, when the pressing parts 133 are formed at both ends of the body part 131, the sizes may be different to match the size of the design layer 117 or the base layer 115 of the sticker 110.

In addition, the adhesion part 135 plays a role in adhering the design layer 117 or the base layer 115 disposed at the topmost part of the sticker 110 and peeling the design layer 117, the base layer 115, and the adhesion layer 113 from the release sheet 111 as a whole. Further, the design layer 117 and the like adhered to the adhesion part 135 are transferred to the upper surface of the nail main body M.

Specifically, the adhesive part 135 is in contact with the upper surface of the design layer 117 or the base layer 115 adhered to the release sheet 111, the pressing part 133 is pressed with fingers to integrally adhere the design layer 117, the base layer 115, and the adhesive layer 113 to the adhesive part 135, and the design layer 117 and the like are peeled off from the release sheet 111. Further, the design layer 117 and the like adhered to the adhesion part 135 are in contact with the upper surface of the nail body M, and the pressing part 133 is pressed with fingers to attach the design layer 117 and the like adhered to the adhesion part 135 to the nail body M.

The adhesive part 135 may be manufactured in the form of a padded sheet or a foam. This maximizes the surface area of the design layer 117 or the base layer 115 adhered to the adhesion part 135 when the design layer 117 or the base layer 115 is adhered to the adhesion part 135 by pressing the adhesion part 135, and prevents the breakage and damage of the design layer 117 or the base layer 115 due to the adhesion part 135 being pressed.

In addition, the adhesion part 135 may be attached to the entire area or some areas of the lower surface of the pressing part 133.

Further, the adhesive part 135 may be formed of one material including one selected from olefin resin, acrylic resin, urethane resin, silicone resin, and rubber, or a mixture thereof, so that the adhesive part 135 has adhesiveness.

Further, in order to attach the design layer 117 or the like to the nail main body M, the adhesiveness between the adhesive layer 113 provided below the design layer 117 or the like and the nail main body M needs to be greater than the adhesiveness between the design layer 117 or the base layer 115 and the adhesive part 135.

Specifically, the viscosity of the adhesive part 135 is preferably 5 to 15000 gf/in.

For example, in the case where the viscosity of the adhesive part 135 is less than 5gf/in, when the design layer 117 and the like are attached to the nail body M, it may not be easy to peel the design layer 117, the base layer 115, and the adhesive layer 113 from the release sheet 111 as a whole, and in the case where the viscosity of the adhesive part 135 exceeds 15000gf/in, the transfer percentage for attaching the design layer 117 and the like to the nail body M may be reduced. Therefore, the viscosity of the adhesive part 135 is preferably 5 to 15000 gf/in.

Meanwhile, when the design layer 117 or the like is adhered to the adhesion part 135 or the design layer 117 or the like adhered to the adhesion part 135 is attached to the nail body M, the user grasps the body part 131 and presses the pressing part 133 with fingers to adhere the design layer 117 or the like to the adhesion part 135 or attach the design layer 117 or the like to the nail body M. In this way, when the design layer 117 and the like are repeatedly pressed via contact, the body portion 131 needs to be elastically restored after the pressing. For this, the body portion 131 is made of an elastically restorable material.

For example, the body part 131 may be formed of a material including one selected from olefin resin, acrylic resin, urethane resin, silicone resin, and rubber, or a mixture thereof.

Meanwhile, as shown in fig. 2, a transfer body 130a according to another embodiment includes a plurality of unit transfer bodies 131a stacked in a height direction. That is, a plurality of unit transferors 131a are stacked in the height direction to form a transferor 130 a. In addition, each unit transfer body 131a includes a body portion 133a and an adhesive portion 135a attached to a lower surface of the body portion 133 a.

The body portion 133a may be a film or sheet made of one selected from the group consisting of: polyvinyl chloride (PVC), Polyethylene (PE), Polyurethane (PU), polypropylene (PP), polyethylene terephthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA), and acrylic resin or a polymer thereof. In addition, the adhesive part 135a according to another embodiment is the same as the above-described adhesive part 135 according to the embodiment, and a detailed description thereof is omitted herein.

The process of transferring the design layer 117 and the like using the transfer body 130a according to another embodiment includes bringing the adhesive portion 135a into contact with the upper surface of the design layer 117 or the base layer 115 adhered to the release sheet 111, pressing the body portion 133a disposed on the adhesive portion 135a with fingers to integrally adhere the design layer 117, the base layer 115, and the adhesive layer 113 to the adhesive portion 135a, and peeling the design layer 117 and the like from the release sheet 111. Further, the design layer 117 and the like adhered to the adhesion part 135a are brought into contact with the upper surface of the nail main body M, and the main body part 133a is pressed with fingers to attach the design layer 117 and the like adhered to the adhesion part 135a to the nail main body M. Meanwhile, the adhesion part 135a constituting the transfer body 130a according to another embodiment is the same as the process of transferring the design layer 117 and the like using the transfer body 130 according to the embodiment as described above, and a detailed description thereof is omitted herein.

In this way, when the adhesion part 135a is repeatedly used, the viscosity of the adhesion part 135a is decreased, and when the viscosity of the adhesion part 135a is decreased, the following operation is performed: the unit transfer body 131a having the respective adhesive sections 135a is separated from the transfer body 130a, and the design layer 117 and the like are attached to the nail main body M using the adhesive sections 135a provided in the new unit transfer body 131 a.

The sticker transfer method using the transfer kit 100 for artificial nails configured as above according to the present disclosure is described below.
