Adhesive sheet for artificial nail

Abstract

An adhesive sheet for an artificial nail comprises a releasable protective film having, at a tip end side of a bare nail to which a double-sided adhesive sheet member is attached, a peeling tongue piece having a width smaller than the width of the double-sided adhesive sheet member and projecting outward from the double-sided adhesive sheet member, wherein the double-sided adhesive sheet member and the releasable protective film are chamfered in a convex R shape from a base end of the peeling tongue piece toward both sides in a width direction.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an adhesive sheet for an artificial nail that allows easy mounting of an artificial nail on a bare nail. BACKGROUND ART [0002] Nowadays women apply nail art on their bare nails or attach artificial nails to their bare nails to create a stylish look. [0003] For a method for attaching an artificial nail to a bare nail, there is an attachment method using glue or double-sided adhesive tape as shown in Japanese Publication No. 2002-17433. [0004] In a method for attaching an artificial nail using glue, the artificial nail needs to be pressed until the glue is cured, and thus, attachment takes time. In addition, when the artificial nail is removed, the glue needs to be dissolved by allowing a chemical agent or a nail polish remover to be soaked between the artificial nail and the bare nail, and thus, it takes time. [0005] On the other hand, in a method for attaching an artificial nail using double-sided adhesive tape, a releas...

AI Technical Summary

Benefits of technology

[0010] As described above, since a releasable protective film has a peeling tongue piece, a double-sided adhesive sheet member together with the releasable protective film is peeled off from a release board, an exposed side of the double-sided adhesive sheet member is mounted on a bare nail, and then, the peeling tongue piece is held by fingertips or the like and the releasable protective film is peeled off from the double-sided adhesive sheet member. By this, without the double-sided adhesive sheet member being attached to a fingertip or the like, an adhesive layer can be beautifully attached to the surface of the bare nail.

[0011] Moreover, since the peeling tongue piece is provided to project outward from the double-sided adhesive sheet member, when, for example, the releasable protective film and the double-sided adhesive sheet member are mounted on the bare nail, the peeling tongue piece can be easily held by fingertips or the like.

[0012] Furthermore, since the double-sided adhesive sheet member and the releasable protective film are chamfered at both sides of the width in a convex R shape from a base end of the peeling tongue piece toward the peeling tongue piece, by aligning an R portion of the double-sided adhesive sheet member with an R portion of a base end or tip end of the bare nail, the double-sided adhesive sheet member can be attached to the bare nail with as little clearance as possible on the bare nail. Accordingly, an artificial nail can be securely attached and fixed to the surface of the bare nail.

[0016] In favour of the structure, the width of the peeling tongue piece can be made small. In addition, when the double-sided adhesive sheet member and the releasable protective film are formed by a punching process using a Thomson, unnecessary portions canbe easily removed. That is, although the releasable protective film can be formed solely of a PET film or a polyvinyl chloride film, for example, when the releasable protective film is formed solely of a PET film, a polyvinyl chloride film, or the like, a sufficient strength can be obtained without additionally providing a reinforcing layer; however, unnecessary portions may not be successfully removed upon performing a punching process. Hence, as described above, by using, as a release layer, a silicone-coated paper that is softer than a PET film or a polyvinyl chloride film, unnecessary portions can be successfully removed.

[0018] In favour of the structure, an adhesive layer of a size that matches the size of a bare nail can be selected and an artificial nail can be securely and properly attached and fixed.

[0020] In favour of the structure, by holding the peeling tongue piece by the fingertips and attempting to peel off the double-sided adhesive sheet member from the release board, the double-sided adhesive sheet member is reliably removed from the release board with the double-sided adhesive sheet member being attached to the releasable protective film side. Accordingly, peeling off from the release board can be easily done.

Problems solved by technology

In a method for attaching an artificial nail using glue, the artificial nail needs to be pressed until the glue is cured, and thus, attachment takes time.

In addition, when the artificial nail is removed, the glue needs to be dissolved by allowing a chemical agent or a nail polish remover to be soaked between the artificial nail and the bare nail, and thus, it takes time.

However, upon removing the release sheet, a fingertip may touch part of the adhesive layer, causing the fingertip to be attached to the adhesive side; accordingly, a problem arises in that there is difficulty in successfully attaching a double-sided adhesive tape to a bare nail.
