FIG. 1 is a sectional view (A) of the artificial nail 100 viewed from the side and a sectional view (B) of the artificial nail 100 seen from the upper side according to an embodiment of the present invention.

The artificial nail 100 may include an artificial nail body 110, an upper back 120, a lower back 130, an adhesive 140 and a release film 150.

The artificial nail body 110 has an upper back surface 120 having a first width ('a' in FIG. 1) and a lower back surface 120 having a second width ('b' (130), and the upper back surface (120) and the lower back surface (130) may be formed to be bent. The first width a of the artificial nail body 110 may correspond to 0.7 to 0.4 times the width of the artificial nail body 110 and the second width b of the artificial nail body 110 may correspond to 0.7 to 0.4 times the width of the artificial nail body 110, 0.0 > 0.3 < / RTI > The artificial nail body 110 may include a step 160 (C in FIG. 1) having a difference between a first width ('a' in FIG. 1) and a second width ('b' in FIG.

The artificial nail body 110 may be manufactured by injection molding an artificial nail body 110 by mixing 5-20 parts by weight of polypropylene (PP) with acrylonitrile-butadiene-styrene (ABS) resin.

ABS resin is a thermoplastic resin that improves mechanical strength, heat resistance and weather resistance while maintaining the excellent permeability, workability and electrical properties of polystyrene (PS). ABS resin has the advantage that it can be colored in any color and can produce a glossy molded article. The ABS resin can be modified to control the composition of the resin and the mixing ratio thereof with other resins, so that the ABS resin can be manufactured to have suitable characteristics depending on the application. [0002] Polypropylene (PP) is widely used because it can be made lightweight, has excellent molding processability, chemical resistance, mechanical properties such as tensile strength and bending strength, excellent thermal properties, and economical advantages . The artificial nail body 110 can be improved in luster and workability by blending polypropylene (PP) with ABS resin. In addition, the artificial nails 100 made of ABS and polypropylene (PP) can be eco-friendly artificial fingernails, both of which are environmentally friendly plastic that does not contain environment hormones and which is harmless to the environment, both of ABS resin and polypropylene (PP).

The artificial nail body 110 may be made of ABS resin composed of 20 to 30 parts by weight of acrylonitrile, 35 to 40 parts by weight of butadiene and 60 to 70 parts by weight of styrene. The high content of styrene can increase gloss and formability. The artificial nail body 110 may be composed of a resin selected from the group consisting of polystyrene (PS) resin, ABS resin, SBS block resin, EVA resin, polycarbonate resin and acrylic resin.

The artificial nail body 110 constitutes the adhesive 140 so that the release film 150 and the lower back surface 130 can be attached to the upper and lower surfaces of the adhesive 140, respectively.

The adhesive 140 may be applied on the lower backside 130 of the artificial nail body 110 and the lower backside 130 may be injection molded into the mold. The bottom backside 130 may include text or images to provide stereoscopic graphics effects. The lower back surface 130 may be formed by wet etching and the adhesive 140 may be provided on the etched portion of the lower back surface 130. The pressure-sensitive adhesive 140 is neutral and can be used as a free glue without toxic components. The adhesive 140 may be applied to the artificial nail body 110 composed of ABS (Acrylonitrile Butadiene Styrene) resin and a mixed resin to have excellent adhesive force.

The pressure sensitive adhesive 140 may include 10 to 30 parts by weight of the nail protecting composition based on 100 parts by weight of the acrylic pressure sensitive adhesive composition. Nail protectors can nourish your nails and protect your fingernails from harmful chemicals such as chemicals. In one embodiment, the nail protectant composition may comprise polyvinyl butyral (PVB) with argan oil, vitamin E, calcium and quinoa proteins, and the like. Arganonil can supply nutrition to nails. Vitamin E and calcium can make nails thick and hard with nail protection and antioxidant action. It also contains quinoa protein ingredients to strengthen the nail surface moisture retention, It is possible to prevent cracking or breaking.

The pressure sensitive adhesive 140 may be coated with a hydrophobic material such as polycarbonate (PC) at a room temperature on a surface to be adhered to the release film 150. By coating the polycarbonate, the surface to be adhered to the release film 150 can be rendered hydrophobic. When the artificial nail body 110 is actually attached to the nail, the surface of the adhesive 140 is modified to be hydrophobic, thereby preventing moisture and organic matter from being adsorbed therein, thereby increasing the sticking rate. In addition, it can have a self-cleaning effect that allows dust or contaminants contaminating the coating surface to be washed away by water. The polycarbonate coating can be performed at room temperature through a simple dip coating process.

The release film 150 is a member for a protective film coated only on one side and can be easily separated from the adhesive 140. [ The release film 150 may be used to prevent the adhesive 140 from being contaminated or the adhesive component from volatilizing from the adhesive 140. The release film 150 may be attached to the adhesive 140 in a bent manner along the lower back surface 130 including the adhesive 140 and may be provided on the upper back surface 120, And the lower back surface 120, 130 can be protected. The release film 150 may include characters or images.

The release film 150 may be coated with silicone on one side or both sides to increase the adhesion while imparting releasability to the surface when separated from the pressure-sensitive adhesive 140 immediately before use. The release film 150 can be manufactured by applying a conductive polymer so as to add an antistatic function to solve the problem that the surface of the film is easily charged when friction is applied. The conductive polymer may be selected from the group consisting of polyaniline, polypyrrole, polythiophene, and copolymers thereof. The conductive polymer may include 0.1 to 5 parts by weight based on 100 parts by weight of the silicone-based binder resin. The release film 150 can reduce product contamination due to electrostatic phenomenon when it is separated from the point spreader 140 by an antistatic function.

The release film 150 may include an unfixed portion of the rim of the artificial nail body 110 (e.g., a portion protruding from the actual nail). Wherein the unadhered portion may include an upper backside 120. The artificial nail 100 may not include the adhesive 140 on the upper back surface 120 of the artificial nail body 110 that is more protruded than the actual nail upper portion. By the design of the non-adhesive portion, it is possible to prevent foreign matter, hair, and the like from sticking to the upper portion of the artificial nail body 110.

The release film 150 on the upper back surface 120 is not attached to the adhesive 140 so that the release film 150 can be easily detached from the artificial nail body 110. The artificial nails 100 can be effectively stacked on the artificial nail storage case without the release film 150 protruding from the outer circumferential surface of the artificial nail body 110.

The lower back surface 130 may be formed by wet etching and the adhesive 140 may be provided on the etched portion of the lower back surface 130. The artificial nail body 110 may include a step 160 (C in FIG. 1) having a difference between a first width ('a' in FIG. 1) and a second width ('b' in FIG.

The artificial nail 100 can include the adhesive 140 on the lower backside 130 by including the step 160 so that the artificial nail 100 can come into close contact with the actual nail 210 when the artificial nail 100 is attached to the actual nail 210 . Since the artificial nails 100 are closely contacted with the actual nails 210, adhesion of moisture and organic matter can be prevented and adhesion can be improved.

The artificial nail 100 can be adhered only by pressing on the actual nail and pressing it in a 'hi' manner, and the artificial nail 100 can be easily detached and attached by lifting the end of the artificial nail 100 up.
