Cosmetic eyelid-shaping tape, method for forming double eyelid using same, and method for producing said tape

Abstract

There is provided a cosmetic eyelid-shaping tape used for performing pseudo shaping on an eyelid by forming a constricted portion on the eyelid by using elastic contractility when a tape-shaped member is stretched with improved adhesiveness of the tape-shaped member to skin on an inner corner of the eyelid and/or on an outer corner of the eyelid. The cosmetic eyelid-shaping tape 1 includes a tape-shaped member including a base material piece capable of being stretched in a longitudinal direction, the base material being formed of a long and narrow synthetic resin that has elastic contractility when stretched, and an adhesive layer coated on both surfaces of the base material piece, and that forms a fold in an upper eyelid by using elastic contractility of the base material piece. An entire adhesive area A in the tape-shaped member decreases in width from a first end side towards a second end side.

1 . A piece of cosmetic eyelid-shaping tape comprising:
 a tape-shaped member including a base material piece capable of being stretched in a longitudinal direction, the base material being formed of a long and narrow synthetic resin that has elastic contractility when stretched, and   an adhesive layer coated on both surfaces or one surface of the base material piece, the cosmetic eyelid-shaping tape being used for performing pseudo shaping on an eyelid by using the elastic contractility of the base material piece to form a constricted portion in the eyelid,   wherein the tape-shaped member includes, on a first end side and a second end side of the tape-shaped member in the longitudinal direction,
 a pair of holding areas to be held with fingertips, and 
 an adhesive area between the pair of holding areas, the adhesive area to be stuck on the eyelid by being stretched to a predetermined length, and 
   wherein an entirety of the adhesive area in the longitudinal direction is formed by a width decreasing section in which a width of the base material piece continuously decreases from the first end side towards the second end side.   
     
     
         2 . (canceled) 
     
     
         3 . The cosmetic eyelid-shaping tape according to  claim 1 ,
 wherein the tape-shaped member is formed in a triangle or a trapezoid in plan view in which a width becomes smaller from a first end towards a second end.   
     
     
         4 . The cosmetic eyelid-shaping tape according to  claim 1 ,
 wherein the base material piece includes at least a first base material layer, and   wherein the first base material layer of the base material piece is elongated when the adhesive area is stretched to the predetermined length, and has elastic contractility in an elongated state.   
     
     
         5 . The cosmetic eyelid-shaping tape according to  claim 4 ,
 wherein the base material piece is formed of a laminated body of the first base material layer formed of a polyolefin resin, and a second base material layer formed of an elastomer resin.   
     
     
         6 . The cosmetic eyelid-shaping tape according to  claim 5 ,
 wherein the first base material layer is formed of a low-density polyethylene resin.   
     
     
         7 . The cosmetic eyelid-shaping tape according to  claim 1 ,
 wherein the cosmetic eyelid-shaping tape is further formed of a synthetic resin that has easy release characteristics against the adhesive layer, and includes a release sheet piece that covers the adhesive layer and that is stuck on the holding areas and the adhesive area of the tape-shaped member, and   wherein the release sheet piece includes an easily breakable portion at a portion corresponding to the adhesive area, the easily breakable portion having a depth reaching a middle in a thickness direction while being provided so as to extend in the width direction, the easily breakable portion being broken by pulling in the longitudinal direction.   
     
     
         8 . The cosmetic eyelid-shaping tape according to  claim 1 ,
 wherein the cosmetic eyelid-shaping tape is further formed of a film having easy release characteristics against the adhesive layer, and includes a release film piece that covers the adhesive layer and is stuck on the adhesive area of the tape-shaped member,   wherein the pair of holding areas are nonadhesive, and   wherein the release film piece is formed shorter than the tape-shaped member, a portion or all of the holding areas being exposed on the first end side and the second end side, and the release film piece extends on the tape-shaped member.   
     
     
         9 . A method for forming a double eyelid by using the cosmetic eyelid-shaping tape according to  claim 1 , the method comprising:
 stretching an adhesive area of the tape-shaped member to the predetermined length by holding and pulling a pair of holding areas of the tape-shaped member in the longitudinal direction;   sticking a portion or all of the adhesive area stretched to the predetermined length on an upper eyelid with the adhesive by abutment against the upper eyelid while the tape-shaped member is kept in a pulled state;   forming a constricted portion along the adhesive area in the upper eyelid by releasing the pulling of the tape-shaped member and elastically shrinking the base material piece in the adhesive area that has been stuck on the upper eyelid; and   forming a fold of the double eyelid by skin of the upper eyelid being bent back at the constricted portion when the upper eyelid is opened.   
     
     
         10 . A method for producing the cosmetic eyelid-shaping tape according to  claim 1 , the method comprising:
 preparing an adhesive sheet on which an adhesive is coated on both surfaces or one surface of a base material sheet formed of a synthetic resin that forms the base material piece; and   obtaining the cosmetic eyelid-shaping tape including the tape-shaped member by cutting the adhesive sheet with a cutting blade.
