Fastening device for extraneous elements in hair

Abstract

The device is formed of a flat polymerized plastic strip ( 1 ) which is on one side provided with locking projections ( 3 ) made of the same material. The locking projections are preferably formed such that they can penetrate natural hair and can be engage with similar locking projections ( 3 ) of a counter-member. The two-dimensional engagement of the fastening device with the one layer of hair ( 7 ) results in a durable attachment of the device in the predetermined position. For attaching extraneous elements ( 6 ) on the fastening device, the plastic strip ( 1 ) is provided with an adhesive layer ( 5 ) on the flat side thereof.

         51 . A fastening device attachable to natural hair, comprising: a thin, two-dimensional plastic strip having one or more extraneous elements on a flat side of the plastic strip facing away from a fastening position, and one or more first locking projections at a fastening side of the plastic strip facing the fastening position, wherein the first locking projections each have a shaped cross-section configured so that, in the fastening position, the first locking projections penetrate the natural hair and interlock with one or more similar second locking projections on a foldable section of the plastic strip. 
     
     
         52 . The fastening device of  claim 51 , wherein the cross-section of the one or more first locking projections is hook-shaped. 
     
     
         53 . The fastening device of  claim 51 , wherein the cross-section of the one or more first locking projections is mushroom head-shaped. 
     
     
         54 . The fastening device of  claim 51 , wherein the fastening side includes between about 10 and about 300 first locking projections that are arranged per cm 2 . 
     
     
         55 . The fastening device of  claim 51 , wherein the foldable section is generated from the plastic strip by a punching step. 
     
     
         56 . The fastening device of  claim 51 , wherein one or more recesses are provided at a bending position of the plastic strip interposed the one or more first and second locking projections to minimize a material-dependent restoring affinity. 
     
     
         57 . The fastening device of  claim 51 , wherein the one or more first and second locking projections each have a material thickness between about 0.2 mm and about 1.5 mm. 
     
     
         58 . The fastening device of  claim 51 , wherein the plastic strip is made of a transparent, deformable plastic. 
     
     
         59 . The fastening device of  claim 51 , wherein the plastic strip has an elongate shape and a surface between about 1.2 cm 2  and about 8 cm 2 . 
     
     
         60 . The fastening device of  claim 51 , wherein the fastening side includes a complete or partial coating that increases the friction coefficient between the natural hair and the fastening side. 
     
     
         61 . The fastening device of  claim 51 , wherein the plastic strip includes an adhesive layer on the flat side, the adhesive layer being a hot-melt adhesive and/or an unsupported acrylate film of about 50 μm to about 300 μm. 
     
     
         62 . The fastening device of  claim 51 , further comprising a presentation surface made of the one or more extraneous elements that is formed on the flat side, wherein the extraneous elements include one or more fibers that are arranged side-by-side in bundles or two-dimensionally. 
     
     
         63 . The fastening device of  claim 62 , wherein the one or more extraneous elements include a plurality of differently dyed fibers. 
     
     
         64 . The fastening device of  claim 62 , wherein the one or more fibers, prior to application to an adhesive layer on the flat side, are sewed together two-dimensionally at a sowing position located on the plastic strip or outside the plastic strip with at least one sewing thread having a thermo-plastically deformable material. 
     
     
         65 . The fastening device of  claim 62 , wherein the one or more extraneous elements applied two-dimensionally on the plastic strip include a fabric containing indicia of numbers, characters, colors, logos, writings, and/or photos. 
     
     
         66 . The fastening device of  claim 62 , wherein the one or more extraneous elements applied two-dimensionally on the plastic strip include a plastic foil containing indicia of numbers, characters, colors, logs, writings, and/or photos, the plastic foil being transparent or colored. 
     
     
         67 . The fastening device of  claim 62 , wherein the one or more extraneous elements applied two-dimensionally on the plastic strip include a thinly rolled metal foil provided with a pattern by punching or etching, wherein the pattern includes numbers, characters, colors, logos, writings and/or photos. 
     
     
         68 . The fastening device of  claim 62 , further comprising one or more decorative elements proximate the presentation surface. 
     
     
         69 . The fastening device of  claim 68 , wherein the decorative elements are pearls, gemstones, Swarovski-stones, sequins or light generating elements attached on the presentation surface of the fastening device. 
     
     
         70 . A fastening device attachable to natural hair, comprising:
 one or more extraneous elements on a flat side of the fastening device facing away from a fastening position;   one or more first locking projections at a fastening side of the fastening device facing the fastening position, the one or more first locking projections each having a hook-shape configured so that the locking projections penetrate natural hair and interlock, when in the fastening position, with similar second locking projections on a foldable section of the fastening device; and   one or more recesses in the fastening device at a bending position interposed the first and second locking projections configured to minimize a material-dependent restoring affinity.
