Air permeable artificial fingernails with removable and reusable adhesive coating

Abstract

This disclosure introduces an innovative cosmetic nail enhancement system comprising air permeable artificial nails with a removable and reusable adhesive coating. Designed to mimic the look and feel of professionally enhanced nails, these artificial nails offer users a versatile range of customization options in size, shape, color, and design, accommodating various personal styles and occasions. The invention's cornerstone is its unique adhesive technology, formulated to ensure a strong yet non-damaging bond with the natural nail, allowing for easy, gentle removal and multiple reapplications, as well as strategically placed micro-perforations to ensure natural nail health. These features not only enhances the product's economic and environmental appeal by promoting reuse but also bridges the gap between traditional permanent enhancements and the demand for flexible, temporary nail decoration solutions. Through this invention, users gain the ability to frequently and conveniently change their nail aesthetics without compromising natural nail health.

What is claimed is: 
     
         1 . An air permeable artificial nail apparatus, comprising:
 an artificial nail body comprising a top surface and an underside surface;   a plurality of micro-perforations extending through the artificial nail body from the top surface to the underside surface;   a pressure-sensitive adhesive layer affixed to the underside surface of the artificial nail body; and   a release liner removably affixed to the pressure-sensitive adhesive layer;   wherein the micro-perforations extend through the adhesive layer and the release liner to maintain air permeability to the natural nail.   
     
     
         2 . The air permeable artificial nail apparatus of  claim 1 , wherein the artificial nail body is constructed from a material selected from the group consisting of acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), polymethyl methacrylate (PMMA), styrene acrylonitrile (SAN), polyethylene terephthalate glycol (PETG), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyurethane (PU), polyvinyl butyral (PVB), polyamide (PA), ethylene-vinyl acetate (EVA), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polybutylene adipate terephthalate (PBAT), polybutylene succinate adipate (PBSA), polyhydroxyalkanoates (PHA), and copolymers or blends thereof. 
     
     
         3 . The air permeable artificial nail apparatus of  claim 1 , wherein the plurality of micro-perforations are configured to have a diameter ranging from 10 microns to 100 microns and a density ranging from 10 to 250 holes per 0.5-inch by 0.5-inch square. 
     
     
         4 . The air permeable artificial nail apparatus of  claim 1 , wherein the pressure-sensitive adhesive layer comprises a solvent-free pressure-sensitive adhesive, wherein the adhesive layer is formulated to provide a peel adhesion ranging from 2 pounds per inch to 60 pounds per inch as measured by ASTM D3330 and a loop tack ranging from 2 pounds per inch to 75 pounds per inch as measured by ASTM D6195. 
     
     
         5 . The air permeable artificial nail apparatus of  claim 1 , wherein the artificial nail body has a thickness ranging from 0.25 mm to 5 mm. 
     
     
         6 . The air permeable artificial nail apparatus of  claim 1 , wherein the artificial nail body comprises a flexible peel-and-stick film constructed from a polymer blend comprising polyurethane, acrylates copolymer, polyester, polyethylene terephthalate, and one or more oxides as colorants, with a thickness ranging from 0.1 mm to 0.5 mm. 
     
     
         7 . The air permeable artificial nail apparatus of  claim 1 , wherein the pressure-sensitive adhesive layer further comprises one or more soothing agents selected from the group consisting of  Aloe Barbadensis  leaf juice,  Ormenis Multicaulis, Enteromorpha Compressa  Extract, and Vitamin E, configured to reduce irritation upon application and removal. 
     
     
         8 . The air permeable artificial nail apparatus of  claim 1 , wherein the pressure-sensitive adhesive layer further comprises one or more colorants selected from the group consisting of titanium dioxide and zinc oxide, configured to provide an opaque appearance. 
     
     
         9 . The air permeable artificial nail apparatus of  claim 1 , wherein the artificial nail body is customizable with decorative elements selected from the group consisting of solid colors, patterns, textures, and pre-applied nail art.
