Description

  The present invention relates to a decorative tool that is used repeatedly by fixing a plurality of decorative pieces for decorating a person to a resin substrate and affixing the decorative piece to the skin of the person, and a method for manufacturing such a decorative tool.

  Conventionally, not only ornaments worn on the human body such as earrings, necklaces and rings, but also a new fashion style of human ornaments called body jewels that are directly applied to the human skin, that is, human skin. Production and sales are carried out.

  As this type of ornament, for example, a plurality of decorative parts are attached in a desired shape on a pressure-sensitive adhesive layer of a base material having a structure in which an adhesive layer, a base material sheet, and a pressure-sensitive adhesive layer are sequentially laminated and integrated. A decorative article with a base material on which a decorative article is formed has been proposed (see, for example, Patent Document 1). In this patent document 1, the base material sheet of the base material of the decorative article with base material indicates a plurality of decorative parts attached to the pressure-sensitive adhesive layer and is attached to the earlobe or other desired part of the body. For example, it is disclosed that papers such as high-quality paper, plastic films such as polyester, and the like are used. Moreover, an adhesive is used for the adhesive layer and the adhesive layer of the base material, and an acrylic adhesive, a rubber adhesive, a silicone adhesive, etc. are disclosed as the adhesive.

  Further, as such a decorative tool, for example, a synthetic resin main body layer made of urethane resin, acrylic resin, silicone rubber, etc., and an adhesive layer formed on one surface of the main body layer and made of an adhesive functioning at room temperature.

By the way, in the decorative article with a base material and the decorative body to be attached disclosed in Patent Documents 1 and 2, an acrylic adhesive and a rubber adhesive as an adhesive layer and an adhesive layer for directly attaching to human skin and the like. Adhesives that are detachable at room temperature, such as silicone adhesives, are used. In Patent Document 2, acrylic medical adhesives used for medical tapes are used. Such a medical pressure-sensitive adhesive has a predetermined adhesive strength so that it can be securely adhered to human skin, of course, to gauze and medical instruments so that gauze and medical instruments can be securely fixed to predetermined parts of the human body. Therefore, safety is taken into consideration so that it can be directly attached to a person's skin or the like and peeled off.
However, acrylic adhesives, rubber adhesives, and silicone adhesives can be applied to or peeled off from human skin at room temperature, but acrylic medical adhesives used for medical tapes, etc. However, since it is not used repeatedly, there is a problem in that if it is repeatedly pasted or peeled off, the adhesive strength decreases, and it cannot be used repeatedly, for example, semi-permanently.

Moreover, like a decorative article with a base material disclosed in Patent Document 1, a plurality of decorations are used for an adhesive layer using an adhesive similar to an adhesive used for an adhesive layer for directly attaching to human skin or the like. Because the parts are attached, it cannot be said that the decorative parts are sufficiently bonded or fixed, and the decorative parts are removed from the pressure-sensitive adhesive layer only after a little force is applied to the decorative parts, or over time. There is a problem that it may peel off, and as a result, there is also a problem that it cannot withstand long-term use.
Moreover, in the sticking decorative body disclosed in Patent Document 2, since the jewelry piece is bonded to the decorative body base, specifically to the main body layer with an adhesive that forms the adhesive layer of the decorative base, Because the decorative body substrate (main body layer) looks dirty and the flexibility of the decorative body substrate (main body layer) decreases due to the curing of the adhesive, the feeling of fit when the decorative body to be attached is applied to the skin There were problems such as lowering.

On the other hand, in the decorative tool disclosed in Patent Document 3, it is necessary to maintain a state of being attached to human skin as a substrate having an attachment surface to which a decorative piece is attached and an attachment surface to be attached to human skin. Since only a substrate made of a gel-like material having a strong adhesive force is used, an adhesive or a medical adhesive as described above in Patent Documents 1 and 2 is applied to the attachment surface to be attached to human skin. Since, for example, Patent Document 2 does not use an adhesive to attach the decorative piece to the substrate. Even if the decorative piece is fixed to the substrate, it looks good, and even if it is used repeatedly, it is possible to maintain a feeling of fitting when it is attached to the skin. Since it does not have a base material sheet or body layer made of, use repeatedly That when, when peeling the accessory from use after human skin, part of the substrate made of gel material is torn off, a part of the accessory has a problem that the tear.
Further, since the decorative piece is attached to the surface of the substrate made of a gel material suitable for adhering to the human skin, it can be said that the decorative piece is sufficiently fixed as in the case of Patent Document 1. However, there is a problem that the decorative piece may peel off from the adhesive layer after a little force is applied to the decorative piece or over time, and as a result, the decorative piece may not be used for a long time. There was also a problem.

  The object of the present invention is to eliminate the above-mentioned problems of the prior art, and to repeatedly use it repeatedly, for example semipermanently and safely, by sticking it on or peeling it off from human skin, that is, a person's skin. Therefore, even if it is peeled off from the human skin, a part of it is not torn off. Also, even if the decorative piece is bonded and fixed to the adhesive layer of the resin substrate, the decorative piece is still in the adhesive layer. There is no fear of peeling off from the skin, it looks good, it is highly safe, it can maintain a fit when it is applied to human skin, that is, a person's skin, and productivity is also improved. The object is to provide a high-priced and inexpensive accessory and a method for manufacturing the same.

  As shown in FIG.1 and FIG.2 (a), the decoration tool 10 of this invention makes a human skin, ie, a person's skin, the target object 12, it affixes on the target object 12, and peels off, and is used repeatedly. A decorative tool having a predetermined design shape (in the illustrated example, a butterfly shape), and includes an adhesive gel film 14, a resin substrate 16, and a decorative layer 18.

The adhesive gel film 14 has a predetermined design shape, both surfaces are adhesive surfaces 14a and 14b, and one of the first adhesive surfaces 14a becomes a peelable application surface 14a for the object 12, and the other The second adhesive surface 14 b is an adhesive surface with the resin substrate 16.
In addition, as for the ornament 10 of this invention, after use, the 1st adhesion surface 14a of the adhesive gel film 14 is peeled off from the target object 12, and as shown in FIG. It is affixed to a peelable resin sheet (protective film) 26 serving as a mount, and stored in a storage case (not shown) or the like, and stored until the next use.

  The resin substrate 16 has the same predetermined design shape as the adhesive gel film 14, has a resin layer 20, and adhesive layers 22 a and 22 b formed on both sides of the resin layer 20. One of the first adhesives The second adhesive surface 14b of the adhesive gel film 14 is bonded to the surface of the layer 22a, and a plurality of decorative pieces 24 are bonded to the surface of the other second adhesive layer 22b to form the decorative layer 18. Is done.

  The decorative piece 24 forming the decorative layer 18 reflects light such as decorative artificial jewels such as rhinestones, imitation jewels such as decorative glass balls and cobblestones (hereinafter referred to as stones) 24a such as decorative jewels, It consists of reflective pieces (hereinafter referred to as glitter) 24b for decorating the human body, such as metal powder and powdery reflective material, which are designed according to the adhesive force of the second adhesive layer 22b of the resin substrate 16. It is fixed at a predetermined position.

The stone 24a used in the present invention is not particularly limited, and any type of stones of various known sizes, shapes, colors, and materials can be used.
Also, the glitter 24b used in the present invention is not particularly limited, and any kind of glitters of various known sizes, shapes, colors, and materials can be used.
The decoration piece 24 used in the present invention is not limited to the stone 24a and the glitter 24b, and any decoration piece 24 can be used as long as the object 12 can be decorated. Any decorative piece can be used.

That is, in the present invention, there is no particular limitation on the size of the stone 24a and the glitter 24b. However, for example, the stone 24a is larger than the glitter 24b, and each grain can be reliably identified. The size is preferably a granule having a size of, for example, 0.5 mm to 20 mm, and the glitter 24b is preferably a powder smaller than the stone 24a and less than 0.5 mm.
The shape of the stone 24a is not particularly limited, and examples thereof include a partial sphere with a flat bottom surface, a partial elliptic sphere, and a polyhedron with a flat bottom surface, such as a hemisphere and a semi-elliptical sphere. Further, the shape of the glitter 24b is not particularly limited, and any shape of powder may be used.

The colors of the stone 24a and the glitter 24b are not particularly limited, and may be white or transparent, may be colored, or may have different gloss or color when reflecting light. . The material of the stone 24a and the glitter 24b is not particularly limited, and may be glassy, amorphous, crystalline, metal, resin, or the like.
Note that the arrangement of the stone 24a and the glitter 24b on the second adhesive layer 22b of the resin substrate 16 is not limited to the illustrated example, and any arrangement is possible as long as the object 12 can be arranged in a predetermined design shape that can be decorated. Also good.

Further, the adhesive gel film 14 used in the present invention is made of an adhesive gel-like material that is harmless to human skin and is mainly used in the fields of medicine and beauty, and has a predetermined design shape. As described above, the first adhesive surface 14a, which is one surface, is a surface to be applied to human skin, and the second adhesive surface 14b, which is the other surface, is a resin. It becomes an adhesive surface of the substrate 16 to the second adhesive layer 22b.
The thickness of the adhesive gel film 14 is not particularly limited, and may be appropriately selected according to the thickness of the resin substrate 16 and the type, size, and amount of the decorative piece 24 of the decorative layer 18. In the range of 0.1 mm to 0.8 mm, it may be used.

The gel-like material that forms such an adhesive gel film 14 is preferably a polymer hydrogel containing at least water and a polyhydric alcohol. For example, as such a polymer hydrogel, a polymer hydrogel used as an adhesive sheet to be attached to a living body disclosed in JP-A-2003-265629 can be exemplified.
That is, the gel material is preferably a medical gel. As such a medical gel, for example, Sekisui Plastics Co., Ltd. sheet type or film type technogel (trade name) can be mentioned. Such a medical gel has been verified for its biological safety based on ISO 10993 “Biological evaluation of medical devices”, which is an international standard, and has extremely high safety.

  The resin substrate 16 is the most characteristic part of the present invention. As described above, the resin substrate 16 has the same predetermined design shape as the adhesive gel film 14 and can be expanded and contracted to become a substrate that supports the decorative device 10. And a first adhesive layer 22a and a second adhesive layer 22b which are formed on both sides of the resin layer 20 and have a predetermined adhesive force described later.

The material of the resin layer 20 of the resin substrate 16 is not particularly limited as long as it is a stretchable resin, and is an olefin resin (polyolefin) such as polyethylene (PE) or a polyester type such as polyethylene terephthalate (PET). It is preferably one selected from the group consisting of resins, acrylic resins, polyamide resins, polycarbonate resins, polystyrene resins, and mixtures thereof, among which olefin resins, particularly polyethylene. Is more preferable.
Further, the material of the first and second adhesive layers 22a and 22b of the resin substrate 16 is not particularly limited as long as it has a predetermined adhesive force to be described later. An acrylic adhesive, a rubber adhesive, It is preferably one type selected from the group consisting of vinyl ether adhesives, urethane adhesives, silicone adhesives, and mixtures thereof, and among them, acrylic adhesives are more preferable.

  In such a resin substrate 16, the adhesive strength of the first and second adhesive layers 22a, 22b is in accordance with JIS Z 0237 “180 degree peeling adhesive strength to the test plate”, at a temperature of 25 ° C. The adhesive layer (the first adhesive layer 22a and the second adhesive layer 22b) of the resin substrate 16 is bonded to the stainless steel plate, and the resin substrate 16 is peeled off 180 degrees when continuously peeled off at a speed of 300 mm / min. It is necessary to be 18-22 N / 25 mm when it is considered as adhesive strength. The adhesive strength of the adhesive layers 22a and 22b is more preferably 20 N / 25 mm.

  The reason is that if the adhesive strength of the adhesive layers 22a, 22b is less than 18 N / 25 mm, the adhesive strength between the second adhesive layer 22b of the resin substrate 16 and the stone 24a or glitter 24b of the decorative piece 24 is insufficient, and the decorative piece 24 Is not sufficiently fixed, and the decorative piece 24 may be peeled off or dropped from the adhesive layer 22b with the addition of force or time, and may not be used for a long time. Adhesion between the pressure-sensitive adhesive surface 14b and the surface of the first pressure-sensitive adhesive layer 22a of the resin substrate 16 becomes insufficient, and there is a possibility that the decorative surface may be damaged due to partial peeling. Since the adhesion between the second adhesive surface 14b of the gel film 14 and the surface of the first adhesive layer 22a of the resin substrate 16 becomes too strong, the second adhesive surface 14b of the adhesive gel film 14 described later and the resin substrate This is because in the bonding process with the surface of the first first adhesive layer 22a, it is difficult to bond the first adhesive layer 22a so as not to cause defects such as bubbles that cause a decrease in decorativeness. In the case where the adhesive surface 14a of the adhesive gel film 14 which becomes the application surface to the object 12 is deteriorated due to long-term use and the adhesive force is reduced, it is difficult to reinforce or replace the adhesive gel film 14. is there. In this case, as a result, the decorative tool 10 of the present invention cannot be used for a long time.

  The thickness of the resin substrate 16, and thus the thickness of the resin layer 20 and the adhesive layers 22 a and 22 b, is not particularly limited, but when peeling the decorative tool 10 from the object 12 or the detachable resin sheet 26 for storage, The thickness of the resin layer 20 is 40 to 100 μm so that the resin layer 20 is not partially broken, thin and curled, and is not thick and the followability to the curved surface of the object 12 is not deteriorated. The thickness of the adhesive layers 22a and 22b is preferably 20 to 50 [mu] m so that the decorative piece 24 can be bonded without falling off. As a result, the thickness of the resin substrate 16 is 80 [mu] m. It is preferable that it is -200 micrometers.

If the thickness of the resin substrate 16 is thick, the resin substrate 16 itself becomes hard and uncomfortable when affixed, and the followability to a curved surface is deteriorated. Therefore, the thinner one is preferable. More preferably, the thickness of the adhesive layers 22a and 22b is more preferably 20 to 40 μm, and the total thickness of the resin substrate 16 is more preferably 80 to 160 μm.
The resin substrate 16 thus configured is not directly attached to human skin, but in order to ensure safety, the biological substrate based on ISO 10993 “Biological evaluation of medical devices”, which is an international standard, is used. It is preferable that safety has been verified.

In the decorative device 10 of the present invention, it is preferable to provide a coat layer 28 that covers the side surface of the decorative device 10 in which the adhesive gel film 14 and the resin substrate 16 are laminated. In this way, when the accessory 10 is used repeatedly, the easily damaged side surface of the accessory 10 can be reinforced to prevent the butterfly shape from collapsing in a predetermined design shape, in the illustrated example, The tool 10 can be used over a long period of time.
Here, the coating layer 28 may be a nail coating agent or a coating agent used for nail polish and may be colorless and transparent, but may be a color coating agent.
Although not shown, the decorative tool 10 of the present invention may be provided with a coat layer for protecting the surface of the decorative layer 18, but this coat layer is colorless and transparent so as not to impair the decorative properties of the decorative piece 24. Preferably there is.

In addition, the peelable resin sheet 26 shown in FIG. 2B is used as a storage board, and any material can be used as long as it can be used as a protective film for the adhesive gel film 14. However, for example, the material of the resin layer 20 of the resin substrate 16 can be used. Further, the thickness of the resin sheet 26 may be the same as the thickness of the resin layer 20 of the resin substrate 16. For example, as the resin sheet 26, for example, a resin film having a thickness of 60 to 125 μm, specifically, a PE film having a thickness of 60 μm, a PET film having a thickness of 100 or 125 μm, or the like can be used.
The decorative tool of the present invention is basically configured as described above.

Next, the manufacturing method of the ornament of this invention is demonstrated.

Although a conventionally well-known protective film can be used as the film 42, for example, the same protective film as the resin sheet 26 used as a storage mount for the ornament 10 can be used. That is, as the resin film 42, the material of the resin layer 20 of the resin substrate 16 and the like can be used, and the thickness thereof is the same as the thickness of the resin layer 20, for example, a resin film of 60 to 125 μm, specifically A PE film with a thickness of 60 μm, a PET film with a thickness of 100 or 125 μm, or the like can be used.

  Moreover, the peeling sheet 34 which protects the 2nd adhesion surface 14b of the adhesive gel film 14 of the gel film packaging body 30, and the peeling sheet which protects the surface of the 2nd adhesion layer 22b of the resin substrate 16 of the substrate packaging body 40 As 44, a conventionally known release sheet can be used. For example, paper such as glassine paper, coated paper, laminated paper, and various plastic films coated with a release agent such as silicone resin can be used. The thickness of the release film may be about the same as the thickness of the resin films 32 and 42, for example, 60 to 125 μm, specifically, a 100 μm thick release sheet.

Next, in step S12, the release sheet 34 of the gel film package 30 is peeled to expose the second adhesive surface 14b of the adhesive gel film 14.
Similarly, in step S14, the peelable resin film 42 of the substrate package 40 is peeled to expose the surface of the first adhesive layer 22a of the resin substrate 16.
Note that these steps S12 and S14 may be performed in the reverse order, and the preparation of the gel film package 30 in step S10 and the peeling of the release sheet 34 of the gel film package 30 in step S12 are continuously performed. Thus, the preparation of the substrate package 40 in step S10 and the peeling of the resin film 42 of the substrate package 40 in step S12 may be performed continuously.

  Next, in step S16, the exposed second adhesive surface 14b of the gel film package 30 and the exposed surface of the first adhesive layer 22a of the substrate package 40 are bonded together, and FIG. ), A bonded sheet 50 of the gel film package 30 and the substrate package 40 is produced.

Therefore, the bonded body 52 having a predetermined design shape can be easily manufactured, and the production cost can be reduced.

Next, in step S20, the release sheet 44 of the bonded body 52 having a predetermined design shape produced in step S18 is peeled off and peeled off, and as shown in FIG. The surface of the adhesive layer 22b is exposed to obtain a bonded body 54 having a predetermined design shape.
Next, in step S22, decorative pieces 24 such as a plurality of stones 24a and glitters 24b are provided on the exposed surface of the second adhesive layer 22b of the bonded body 54 having the predetermined design shape obtained in step S20. The decorative tool 10 of the present invention as shown in FIG.

  In this step S22, first, the stone 24a is first arranged and fixed on the surface of the second adhesive layer 22b of the resin substrate 16 according to a predetermined design arrangement, and then the glitter 24b is fixed to the second adhesive layer 22b. Scatter or place on the surface according to a predetermined design arrangement. This is because if the glitter 24b is fixed to the surface of the second adhesive layer 22b of the resin substrate 16 before the stone 24a, the glitter 24b enters between the stone 24a and the second adhesive layer 22b, and the stone 24a This is because the contact area between the first adhesive layer 22b and the second adhesive layer 22b is reduced, the adhesive force between the two is weakened, and the stone 24a may be easily peeled off or fall off.

  In this step S22, the decorative pieces 24 such as stones 24a and glitters 24b arranged and fixed on the surface of the second adhesive layer 22b of the resin substrate 16 according to a predetermined design arrangement are attached to the second adhesive layer of the resin substrate 16. It is preferable that the stone 24a and the glitter 24b are firmly and firmly bonded and fixed to the surface of the second adhesive layer 22b by applying pressure from a direction perpendicular to the surface of the 22b.

Further, in this step S22, the side surface of the decorative device 10 in which the adhesive gel film 14 and the resin substrate 16 are laminated, that is, a cut-out surface or a punched surface, is used as a nail coating agent or nail polish, Alternatively, it is preferable to form the coat layer 28 by coating a color coating agent.

In addition, since the resin substrate 16 is not directly attached to the human skin, the resin substrate 16 does not necessarily have to pass a biological safety test based on ISO 10993, but is directly attached to the human skin. Since the resin substrate 16 is used for the accessory 10, it is preferable that the biological safety based on ISO 10993 is also verified.

By the way, as a double-sided adhesive resin substrate having a predetermined adhesive strength and whose biological safety based on ISO 10993 has been verified, there is a double-sided medical tape, particularly a double-sided tape for skin application. Among these double-sided medical tapes, like the resin substrate 16 described above, the adhesive gel film 14 is sufficiently fixed so that the decorative piece 24 does not peel off or fall off, and does not cause partial peeling. Adhesiveness of the adhesive layer of the double-sided adhesive tape for skin application is such that the adhesive surface 14b is sufficiently adhered and has adhesive strength such as being able to be bonded without causing defects such as bubbles. In accordance with JIS Z 0237 “180 degree peeling adhesive strength to test plate”, at a temperature of 25 ° C., a double-sided tape adhesive layer was bonded to a polypropylene plate, and the double-sided tape was continuously peeled off at a speed of 300 mm / min. A double-sided tape that is 2.4 to 3.0 N / cm, more preferably a double-sided tape that is 2.7 N / cm It is also possible to have.
By using such a double-sided medical tape as the resin substrate 16 and a medical gel as the adhesive gel film 14, the material of the main constituent elements of the jewelry of the present invention is biological safety based on ISO10993. Can be made extremely safe, and as a result, the accessory of the present invention itself can be made extremely safe.
As such a double-sided tape, a double-faced tape 1522 for skin application made by 3M Healthcare Co., Ltd. can be used.
