The two sides of the adhering layer are adhesive, one side is fixed to the adhesion-resistant layer, and the other side is fixed to the paster layer. The shape of the adhering layer is matched with the shape of each nail needing adhesion. The paster is characterized in that annular cutting lines are arranged on the adhesion-resistant layer, the adhering layer and the paster layer respectively and an indentation line is arranged on the inner side of the annular cutting line of the adhering layer. Further, the paster for nail beautification is provided with the annular cutting lines so that the paster can flexibly adhere to the nails according to the sizes of the different nails, and therefore the paster adheres to the surface of each nail; a protruding piece is designed so that the adhering layer can be separated from the adhesion-resistant layer and the paster layer and the paster can adhere to each nail.
KR 101 361 040 B1 discloses a cosmetic sticker set. The cosmetic sticker set comprises: a base layer on which patterns are printed, and a three-dimensional ornament unit with shining material such as jewels and the like on the upper surface of the base layer, wherein the three-dimensional ornament unit additionally comprises: a reflective layer having shining properties printed on the upper surface of the base layer; a transparent coating paint layer which is printed on the place where the reflective layer is formed among the upper surfaces of the base layer, and which allows light to penetrate on the reflective layer; and a three-dimensional layer adhesively applied to the surface of the coating paint layer.
In general, a design layer that is attached to a nail main body of an artificial nail is formed from a film of a stiff material and has a flat shape, so wrinkles occur in the design layer while the design layer is attached to the nail main body having a 3-dimensional curve.
Accordingly, to solve the above-described problem, conventionally, an operation of removing winkles is performed after attaching the design layer to the nail main body.
However, because the user has to manually remove wrinkles occurred in the design layer, novices having a low ability to perform an operation spend a long operation time in removing wrinkles and there is a rise in production cost of artificial nails. Additionally, the design layer may be contaminated with impurities in the process of removing wrinkles.
Accordingly, there is a need for an approach to preventing wrinkles from occurring when attaching the design layer to the nail main body.

Referring to FIGS. 1 to 3, the transfer assembly set 100 for an artificial nail according to the present disclosure includes a sticker 110 having a design layer 117, a base layer 115 provided on the lower surface of the design layer 117 and an adhesive layer 113 provided on the lower surface of the base layer 115 and peelably adhered to a release sheet 111, and a transfer body 130, 130a to integrally peel the design layer 117, the base layer 115 and the adhesive layer 113 adhered to the sticker 110 and attach the peeled design layer, base layer and adhesive layer 117, 115, 113 to a nail main body M of an artificial nail 200. Additionally, the base layer 115 according to this embodiment may be provided on the upper layer of the design layer 117.
The transfer assembly set 100 for an artificial nail according to this 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 above the nail main body M, and presses the design layer 117, the base layer 115 and the adhesive layer 113 onto the nail main body M upon contact, so that the design layer 117, the base layer 115 and the adhesive layer 113 can be easily attached to the nail main body M using the transfer body 130, 130a.
Referring to FIG. 3, the sticker 110 according to this embodiment has the adhesive layer 113 peelably adhered to the upper surface of the release sheet 111, and the base layer 115 and the design layer 117, or the design layer 117 and the base layer 115 stacked on the upper surface of the adhesive layer 113 in a sequential order.
The release sheet 111 may be manufactured by surface coating with silicone, Teflon and fluorine on a film or a sheet made of one selected from paper, poly vinyl chloride (PVC), polyethylene (PE), polyurethane (PU), polypropylene (PP), polyethylene phthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA) and acrylic resin or polymers thereof.
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 stacked on the upper surface of the release sheet 111 in a sequential order. Additionally, 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 36 dyne/cm or less per unit width, to easily peel the adhesive layer 113 off from the release sheet 111 and prevent the tearing and pop-up phenomena of the release sheet 111.
Additionally, the tackiness of the adhesive layer 113 is preferably 116-9,646 N/m (300-25,000 gf/in). The tackiness measurement may be performed in accordance with ASTM D3330 180 degree PEEL TEST.
For example, when attaching the adhesive layer 113 having the base layer 115 and the design layer 117 stacked thereon to the nail main body M of the artificial nail 200, in case that the tackiness of the adhesive layer 113 is less than 116 N/ m (300 gf/in), the adhesive layer 113 is spaced apart from the nail main body M and it is more likely to be separated from the nail main body M, and in case that the tackiness of the adhesive layer 113 exceeds 9,646 N/m (25,000 gf/in), the nail main body M may be damaged when the user separates the adhesive layer 113 from the nail main body M for replacement purposes.
Accordingly, the tackiness of the adhesive layer 113 is preferably 116-9,646 N/m (300-25,000 gf/in).
In this embodiment, the base layer 115 may be stacked on the upper surface of the adhesive layer 113 as shown in FIGS. 3(A) and 3(B) or on the upper surface of the design layer 117 as shown in FIGS. 3(C) and 3(D).
The base layer 115 may be a film or a sheet made of one selected from poly vinyl chloride (PVC), polyethylene (PE), polyurethane (PU), polypropylene (PP), polyethylene phthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA) and acrylic resin or polymers thereof.
Additionally, although not shown, a color ink may be printed on the upper surface or the lower surface of the base layer 115 by one selected from screen, offset and gravure printing methods.
In this instance, 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 areas and each area may be printed in different colors or predetermined colors repeatedly.
The colors printed on the base layer 115 may achieve more unique color reproduction by projection on a transparent hologram film in case that the design layer 117 as described below is formed from a transparent hologram film.
Additionally, although not shown, a metal thin film of aluminum (Al), nickel (Ni) and chrome (Cr) may be deposited on the upper surface and the lower surface of the base layer 115. The metal thin film may be manufactured transparently or opaquely according to the stack thickness. The metal thin film deposited on the base layer 115 can provide a variety of metallic sensations and hologram effects.
In this 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 hologram film having various hologram patterns and designs formed on one surface of a base film. The hologram film varies colors or designs depending on viewing directions.
Additionally, the base film used in the transparent hologram film may be manufactured from polymer resin that is identical or similar to the material of the base layer 115 described above.
Meanwhile, the design layer 117 formed from a transparent hologram film or sheet has a stiff material, and thus especially when the design layer 117 is attached to the nail main body M having a 3-dimensional (3D) curve, wrinkles may occur in the design layer 117.
Accordingly, in this embodiment, a plurality of first die-cut lines 118 is formed in the design layer 117 to prevent wrinkles from occurring in the design layer 117 when attaching the design layer 117 to the nail main body M. That is, when attaching the design layer 117 of a flat shape to the nail main body M having a 3D curve, wrinkles may occur in the design layer 117 due to the radius of curvature of the nail main body M, and the wrinkles may be prevented by adjusting the length, shape and interval of the first die-cut lines 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 is divided by the plurality of first die-cut lines 118 and adhered to the nail main body M by the medium of the adhesive layer 113. That is, the design layer 117 is divided into the plurality of unit design layers 117a by the plurality of first die-cut lines 118.
Additionally, one side end of the first die-cut lines 118 cuts the outer surface of the design layer 117. Additionally, the other side end of the first die-cut lines 118 disposed in the lengthwise direction (Y-direction) of the design layer 117 cuts the design layer 117 inwards from the lengthwise direction (Y-direction) outer surface of the design layer 117 by at least 5% relative to the length of the design layer 117, and the other side end of the first die-cut lines 118 disposed in the widthwise direction (X-direction) of the design layer 117 cuts the design layer 117 inwards from the widthwise direction (X-direction) outer surface of the design layer 117 by at least 5% relative to the width of the design layer 117. In this instance, when the other side ends of the first die-cut lines 118 disposed at two sides of the design layer 117 in lengthwise direction (Y-direction) and widthwise direction (X-direction) are 50% relative to the length and width of the design layer 117, the first die-cut lines 118 cut through the design layer 117 as shown in FIGS. 4(B) and 4(C).
Additionally, the total length of the first die-cut lines 118 formed in the design layer 117 is preferably 3-500% relative to the length of the outer surface of the design layer 117, and the total area of the first die-cut lines 118 is preferably 0.5-25% relative to the surface area of the design layer 117. Here, the total area of the first die-cut lines is the sum of multiplication of the widths and lengths of the first die-cut lines 118 formed in the design layer 117.
When the total length of the first die-cut lines 118 is less than 3% and the total area of the first die-cut lines is less than 0.5%, wrinkles may occur in the design layer 117, and when the total length of the first die-cut lines 118 exceeds 500% and the total area of the first die-cut lines exceeds 25%, the stiffness of the design layer 117 itself may reduce.
Specifically, as shown in FIGS. 4(A), 4(B) and 4(C), the plurality of first die-cut lines 118 may include a plurality of linear die-cut lines c1 having a predetermined width formed in the design layer 117. In FIGS. 4(A) and 4(B), the first die-cut lines 118 go across in the lengthwise direction (Y-direction) and widthwise direction (X-direction) of the design layer 117, and in FIG. 4(C), the first die-cut lines 118 go across in the diagonal direction.
Additionally, 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 with an increasing or decreasing width inwards from the outer surface of the design layer. Additionally, as shown in FIG. 4(E), the plurality of first die-cut lines 118 according to still another embodiment may include a plurality of linear 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 FIGS. 4(A), 4(D) and 4(E), the design layer 117 may further include a connecting part 119 formed between the first die-cut lines 118 to prevent the separation of the plurality of unit design layers 117a.
When the design layer 117 is divided into the plurality of unit design layers 117a by the plurality of first die-cut lines 118, the connecting part 119 is provided to prevent the unit design layers 117a from being separated into pieces by the plurality of first die-cut lines 118. That is, to prevent the design layer 117 from being separated 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 this embodiment, the connecting part 119 is provided between the first die-cut lines 118.
Additionally, as shown in FIG. 4(F), the plurality of first die-cut lines 118 according to still another embodiment not according to the present invention include linear die-cut lines c1 and tapered die-cut lines c2 to separate the design layer 117 into a plurality of unit design layers 117a. In this instance, the base layer 115 and the adhesive layer 113 may be provided on the lower surface of each of the separated unit design layers 117a.
Additionally, as shown in FIG. 4(G), the plurality of first die-cut lines 118 according to still another embodiment not according to the present invention may include curved die-cut lines c3 having a
predetermined width in the design layer 117. In this instance, the design layer 117 may be separated into a plurality of unit design layers 117a by the curved die-cut lines c3, or the design layer 117 may have a connecting part (not shown) between the curved die-cut lines c3 to prevent the separation of the plurality of unit design layers 117a.
Meanwhile, although FIGS. 4(A) to 4(G) show the first die-cut lines 118 formed in the design layer 117 according to this embodiment, the scope of protection 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 die-cut lines 116 may be formed in the base layer 115 at locations corresponding to the plurality of first die-cut lines 118 formed in the design layer 117.
The base layer 115 also has a stiff material, so wrinkles may occur in the base layer 115 when the base layer 115 is attached to the nail main body M having a 3D curve, and thus the plurality of second die-cut lines 116 is formed in the base layer 115 at locations corresponding to the first die-cut lines 118.
Additionally, as shown in FIGS. 3(B) and 3(D), a plurality of third cut-die lines 114 may be formed in the adhesive layer 113 at locations 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 case that 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 main body M having a 3D curve, and thus the plurality of third die-cut lines 114 may be formed in the adhesive layer 113 at locations corresponding to the first die-cut lines 118 and the second die-cut lines 116.
The transfer body 130, 130a according to this embodiment plays a role in easily peeling the design layer 117, the base layer 115 and the adhesive layer 113 adhered to the release sheet 111 integrally off from the release sheet 111, and easily attaching to the nail main body M.
As shown in FIG. 1, the transfer body 130 according to an embodiment includes a main body part 131, a pressing part 133 that extends from the main body part 131 and is bent, and an adhesion part 135 attached to the lower surface of the pressing part 133.
The main body part 131 may be formed in the shape of a long rod to allow the user to hold, but the scope of protection of the present disclosure is not limited thereto, and any shape the user can hold is available.
Additionally, the pressing part 133 extends from one or two ends of the main body part 131 and is bent, and may be formed in a flat shape that allows the user to press the upper surface with a finger.
Additionally, the pressing part 133 may be formed in a curved shape having a predetermined radius of curvature. When the pressing part 133 is formed in a curved shape, as shown in FIG. 5A, a widthwise direction radius of curvature R1 of the pressing part 133 when viewed from the direction A of FIG. 1 may be 10-360 mm, and as shown in FIG. 5B, a lengthwise direction radius of curvature R2 of the pressing part 133 when viewed from the direction B of FIG. 1 may be 30-400 mm.
Additionally, the adhesion part 135 as described below is detachably attached to the lower surface of the pressing part 133.
Additionally, when the pressing part 133 is formed at two ends of the main body part 131, sizes may be different to match the size of the design layer 117 or the base layer 115 of the sticker 110.
Additionally, the adhesion part 135 plays a role in adhering the design layer 117 or the base layer 115 disposed at the topmost of the sticker 110 and integrally peeling the design layer 117, the base layer 115 and the adhesive layer 113 off from the release sheet 111. Additionally, the design layer 117, etc. adhered to the adhesion part 135 is transferred to the upper surface of the nail main body M.
Specifically, the adhesion part 135 comes into 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 a finger to integrally adhere the design layer 117, the base layer 115 and the adhesive layer 113 to the adhesion part 135, and the design layer 117, etc. is peeled off from the release sheet 111. Additionally, the design layer 117, etc. adhered to the adhesion part 135 comes into contact with the upper surface of the nail main body M, and the pressing part 133 is pressed with a finger to attach the design layer 117, etc. adhered to the adhesion part 135 onto the nail main body M.
The adhesion part 135 may be manufactured in the form of a cushioned sheet or foam. This is to maximize the surface area of the design layer 117 or the base layer 115 adhered to the adhesion part 135 in adhering the design layer 117 or the base layer 115 to the adhesion part 135 by pressing the adhesion part 135, and to prevent the breakage and damage of the design layer 117 or the base layer 115 caused by the adhesion part 135 being pressed
Additionally, the adhesion part 135 may be attached to the entire area or some areas of the lower surface of the pressing part 133.
Additionally, the adhesion part 135 may be formed from a material including one selected from olefin resin, acrylic resin, urethane resin, silicone resin and rubber or mixtures thereof, so that the adhesion part 135 has tackiness.
Additionally, to attach the design layer 117, etc. to the nail main body M, the tackiness between the adhesive layer 113 provided below the design layer 117, etc. and the nail main body M needs to be larger than the tackiness between the design layer 117 or the base layer 115 and the adhesion part 135.
Specifically, the tackiness of the adhesion part 135 is preferably 2-5,787 N/m (5-15,000 gf/in).
For example, when attaching the design layer 117, etc. to the nail main body M, in case that the tackiness of the adhesion part 135 is less than 2 N/m (5 gf/in), it may not be easy to integrally peel the design layer 117, the base layer 115 and the adhesive layer 113 off from the release sheet 111, and in case that the tackiness of the adhesion part 135 exceeds 5,787 N/m (15,000 gf/in), the percentage of transfer for attaching the design layer 117, etc. to the nail main body M may be reduced. Accordingly, the tackiness of the adhesion part 135 is preferably 2-5,787 N/m (5-15,000 gf/in).
Meanwhile, when adhering the design layer 117, etc. to the adhesion part 135 or attaching the design layer 117, etc. adhered to the adhesion part 135 onto the nail main body M, the user holds the main body part 131 and presses the pressing part 133 with a finger to adhere the design layer 117, etc. to the adhesion part 135 or attach the design layer 117, etc. to the nail main body M. In this way, when repeatedly pressing the design layer 117, etc. upon contact, the main body part 131 needs to be resiliently recovered after pressed. To this end, the main body part 131 is manufactured from a material capable of elastic recovery.
For example, the main body part 131 may be formed from a material including one selected from olefin resin, acrylic resin, urethane resin, silicone resin and rubber or mixtures thereof.
Meanwhile, as shown in FIG. 2, the transfer body 130a according to another embodiment includes a plurality of unit transfer bodies 131a stacked in the heightwise direction. That is, a plurality of unit transfer bodies 131a is stacked in the heightwise direction to form a transfer body 130a. Additionally, each unit transfer body 131a includes a main body part 133a and an adhesion part 135a attached to the lower surface of the main body part 133a.
The main body part 133a may be a film or a sheet made of one selected from poly vinyl chloride (PVC), polyethylene (PE), polyurethane (PU), polypropylene (PP), polyethylene phthalate (PET), polyolefin elastomer (POE), ethylene-vinyl acetate copolymer (EVA) and acrylic resin or polymers thereof. Additionally, the adhesion part 135a according to another embodiment is the same as the above-described adhesion part 135 according to an embodiment, and its detailed description is omitted herein.
