  Okudane is known as a form of double folds. The back duplex means a state in which a cocoon covers an original double line (a heavy line). That is, the double line is hidden and is difficult to see from the outside. When forming a double fold with the double fold forming tape in the back duplex, it is more important to lift the covered fold than to make it difficult to fold. In addition, it is said that about 25% of Japanese people are Okudu.

  Patent Document 1, Patent Document 2, Patent Document 4 and Patent Document 5 use polyester and polypropylene which are hard base materials. However, in the curved folds of puffy East Asians with a lot of fat, double fold-forming tape may float from the corners of the eyes and the ends of the eyes and peel off when applied for a long time. As a result, there may be a problem in use such that the floating part of the hard base material is tinged.

  In addition, a double wrinkle forming tape using only a hard material such as polyester as the base material of the adhesive tape may be lifted at both ends by a restoring force during wearing and use, and may be peeled off.

  Moreover, it can also stick to a ridge with a strong adhesive so that the both ends of a double ridge forming tape may not float. However, the use of a strong pressure-sensitive adhesive may affect the skin such as exfoliation of the stratum corneum, such as peeling off the stratum corneum of the upper eyelid when the user peels off the double wrinkle-forming tape.

  In addition, the double wrinkle forming tapes of Patent Document 1 and Patent Document 2 use a hard material (polyester or polypropylene) having a width of about 1.5 mm to 2.0 mm. However, since the members of Patent Document 1 and Patent Document 2 are made of a hard material, there is a possibility that the members cannot move flexibly due to blinking or the like.

  Further, the double wrinkle-formed products in Patent Document 4 and Patent Document 5 are made of a non-stretchable strip material and are made of a hard material (polyester or polypropylene) having poor shrinkage, so that they are curved by the movement of the eyelid blinking. There was a risk that it would not be possible to achieve high adhesion for a long time on the heel.

  That is, the upper eyelid on which the double eyelid forming tape is pasted has an average time of blinking of 100 to 150 ms, and it is performed by an adult a dozen times or more per minute. Coupled with being the thinnest part of the skin, the upper arm requires a very delicate movement. It is required to prevent the application of a force that hinders the movement of the upper eyelid.

  In addition, although Patent Document 3 does not describe the material of the double eyelid tape, if a hard material (polyester or polypropylene) having poor shrinkage is used, Patent Document 1, Patent Document 2, and Patent Document 4 are used. Various problems similar to those of Patent Document 5 occur. Also, if the double eyelid tape is made of a soft material such as polyethylene, there is a possibility that the back double cannot be supported due to its flexibility.

  Therefore, the double wrinkle forming tape of the present invention can support a wrinkle covered with a back double, etc. while lifting it, can be used for a long time, and can reduce the feeling of foreign objects during use. An object of the present invention is to provide a double wrinkle forming tape capable of forming a natural double wrinkle during use.

  In order to achieve the above object, the double wrinkle-forming tape of the present invention is a double wrinkle-forming tape that is provided with an adhesive layer on at least one side and is attached to a wrinkle, and the double wrinkle-forming tape is bonded to each other Provided with a two-layer strip-shaped base material, one base material is made of a material more flexible than the other base material, the other base material is shorter in the longitudinal direction than the one base material, It is characterized by being bonded only to the central part in the longitudinal direction of the one base material.

  Further, in the double wrinkle forming tape of the present invention, the one base material is made of a material that expands and contracts by movement of the heel, and the other base material is made of a material that does not expand and contract by the movement of the heel. It is characterized by that.

  Moreover, the double fold forming tape of the present invention is characterized in that both end portions in the longitudinal direction are constituted only by the one base material.

  Further, in the double fold forming tape according to the present invention, the one base material and the other base material are configured to have the same width in the short direction, and the edges of the same width match. Features.

  Further, the double fold forming tape of the present invention has an arcuate shape formed by an outer peripheral edge and an inner peripheral edge, and a central angle of the arc of the outer peripheral edge and a central angle of the arc of the inner peripheral edge are the arcs of the outer peripheral edge. The center angle of is larger.

  The double wrinkle forming tape of the present invention is characterized in that the arc of the outer peripheral edge is curved along a double line of the wrinkles.

  In the double wrinkle forming tape of the present invention, the surface on which the one base material is arranged is located on the eyeball side of the eyelid, and the surface on the side on which the other base material is arranged is opposite to the eyeball side of the eyelid It is arranged on the side.

  The double wrinkle forming tape of the present invention is characterized in that an adhesive layer is provided on both sides.

  According to the present invention, the double wrinkle forming tape includes two layers of strip-shaped base materials bonded to each other, and one base material is composed of a material (more flexible material) that expands and contracts by the movement of the wrinkles, The other base material is made of a material that does not expand or contract depending on the movement of the eyelid (a material that is less flexible than one base material). The base material supports the eyelids to be covered, and in the closed eye state, the base material that expands and contracts by the movement of the eyelids expands and contracts according to the skin of the extended eyelids. The double wrinkle forming tape using only a material that does not expand and contract as in the past feels a tingling sensation at both ends of the wrinkle. In the double wrinkle forming tape of the present invention, since the stretchable material is disposed at both ends in the longitudinal direction, the material disposed at both ends of the scissors expands and contracts due to the motion of the scissors. Can be resolved. Thereby, the user does not feel uncomfortable and can form a natural double fold.

  Further, the double fold-forming tape of the present invention comprises two layers of strip-like base materials bonded to each other, one base material is made of a material that is more flexible than the other base material, and the other base material is , The longitudinal direction is shorter than one base material, it is bonded only to the longitudinal center part of one base material, and both ends in the longitudinal direction are composed of only one base material. It is possible to relax the restoring action of the other base material that does not expand and contract, and both ends are in use during use like a double fold forming tape that uses only a hard base material. It does not float and peel off, and can be used for a long time.

  Furthermore, the double wrinkle forming tape of the present invention is composed of only one base material whose both ends in the longitudinal direction expand and contract, and therefore, the other base material that does not expand and contract by holding (fixing) both ends of one base material. It is further prevented that both ends are lifted and peeled off during use due to restoring force.

  In addition, the double wrinkle forming tape of the present invention has an arcuate shape formed by the outer peripheral edge and the inner peripheral edge, the arc of the outer peripheral edge is curved along the double line of the reed, and further, Since one material made of softer material is arranged at both ends of the eyes, etc., because one material expands and contracts due to the movement of the eyelid, it can form a thin double line and create a natural impression .

  In addition, since the double wrinkle forming tape of the present invention does not expand and contract, it is possible to reduce the size of the substrate that feels uncomfortable, so that it is possible to relieve the discomfort of wrinkles. In addition, by providing base materials made of flexible materials on the left and right sides of the base material that does not expand and contract, the method of application is changed according to the shape of the eyes that differ from each other (the shape of the eyelids), creating a natural and beautiful double eyelid. It is possible to form.

  Further, the double wrinkle forming tape of the present invention can be supported by lifting the wrinkles covered by the back double by providing a non-stretchable layer at the center in the longitudinal direction of the stretchable tape. It is possible to form a thin double line (a double line) with one material made of a softer material at both ends of the eye.

FIG. 5A shows the eye open state and FIG. 5B shows the eye closed state. Show. It is sectional drawing explaining the state which mounted | wore with the double fold forming tape in the back view by planar view. It is a front view for explaining a comparison between the state of the conventional double wrinkle forming tape and the state of the double wrinkle forming tape of the present invention, (a) shows the state of the conventional double wrinkle forming tape wrinkle, (B) shows the mounting state of the scissors of the double scissors forming tape of the present invention.

  Hereinafter, with reference to drawings, the form for implementing the tape for double wrinkle formation by this invention is demonstrated. The double wrinkle forming tape according to the present invention comprises two layers of strip-like base materials bonded to each other, one base material is made of a material that is more flexible than the other base material, The length of the base material is shorter than that of one base material, and the base material is bonded only to the central portion in the longitudinal direction of one base material. It is composed of a material that does not expand or contract depending on the movement of the material (a material that does not easily expand or contract).

  As a result, it is possible to support the folds covered by the back duplex while lifting them, and to use them for a long time, and to reduce the feeling of foreign objects during use.

  1A is a cross-sectional view taken along the longitudinal direction showing the structure of a double fold forming tape, FIG. 1B is a plan view of the double fold forming tape, and FIG. 1C is a plurality of double folds. It is the figure which affixed the forming tape on the adhesive surface protection sheet. As shown in FIG. 1 (a), the double fold-forming tape 1 includes a stretchable tape 3 in which adhesive layers 5 and 6 are provided on both sides of a strip-like base material 4, and adhesive surface protection that covers the adhesive layer 5. And a base material 25. As the base material of the stretchable tape 3, polyethylene 4 having stretchability is suitable, and the adhesive layers 5 and 6 are applied to both sides of the polyethylene 4.

  Further, as shown in FIGS. 1 (a) and 1 (b), a non-stretchable substrate made of a non-stretchable base material that does not stretch due to the movement of the heel at the center in the longitudinal direction of the adhesive layer 6 on one side of the stretchable tape 3 is used. The stretchable layer 15 is laminated via the pressure-sensitive adhesive layer 6 and fixed so as not to be peeled off. The term “non-stretching” means that there is little expansion / contraction even when a force is applied from the outside, and includes that it is difficult to expand / contract. In the present invention, for example, to bend along the shape of the heel when sticking the heel, and to sufficiently support the heel without deformation when blinking also means non-stretching.

  As a base material of the non-stretchable layer 15 indicated by a dotted line in FIG. 1B, polyester 16 having a non-stretchable layer is suitable, and the polyester 16 is in close contact with one surface of the stretchable tape 3 through the adhesive layer 6. doing. Moreover, as for the polyester 16 as a base material of the non-stretchable layer 15, the adhesive layer 17 is apply | coated to the surface opposite to the stretchable tape 3 side.

  As shown in FIG. 1B, the double fold forming tape 1 has a shape in which the stretchable tape 3 is curved in an arch shape, and has stretchable portions 18 at both ends of the non-stretchable layer 15. The stretchable portions 18 located on both sides of the non-stretchable layer 15 are portions where the nonstretchable layer 15 in the stretchable tape 3 is not laminated, and can be stretched by the movement of the heel when pasted on the heel. Is possible. Further, the stretchable tape 3 and the non-stretchable layer 15 are configured to have the same width in the short side direction, and the edges of the same width coincide with each other.

  Thus, in the double fold forming tape 1, the stretchable tape 3 is made of a material that is more flexible than the non-stretchable layer 15, and the nonstretchable layer 15 is shorter in the longitudinal direction than the stretchable tape 3, and the longitudinal direction of the stretchable tape 3 It is attached only to the center.

  Further, as shown in FIG. 1A, the release paper 26 as the adhesive surface protection base material 25 has a rectangular shape and is provided so as to cover the entire surface of the stretchable tape 3.

  Moreover, as shown in FIGS. 1 (a) and 1 (c), the double fold forming tape 1 is adhered to the non-stretchable layer 15 through the pressure sensitive adhesive layer 17 in a peelable state. A plurality are placed on the top.

  Hereinafter, the members constituting the double fold forming tape 1 will be described.

  The material of the base material in the stretchable tape 3 is preferably polyethylene 4. The polyethylene 4 is classified into high density polyethylene, medium density polyethylene, and low density polyethylene according to the density range. Of these, low density polyethylene is most preferred.

  When high-density polyethylene and medium-density polyethylene are used, a feeling of wearing is given to the wearing feeling, whereas a very excellent fit can be obtained by using low-density polyethylene.

  The thickness of the polyethylene 4 as the base material in the stretchable tape 3 is particularly preferably 50 to 80 μm, more preferably 40 to 90 μm, and preferably 20 to 100 μm.

  The material for the substrate 4 may be polyurethane or rayon nonwoven fabric in addition to polyethylene.

  Adhesive components in the adhesive layers 5, 6, and 17 used for the stretchable tape 3 and the like are required to have adhesion compatibility to wrinkles during use and resistance to adhesion (sustainability) to oils and fats, sweat and tears. It is done.

  Polyethylene is suitable as an adhesive material having such properties. When the base material 4 is polyethylene, an adhesive component containing an acrylic adhesive as a main component and a tackifier as the other component is suitable.

  The acrylic pressure-sensitive adhesive is composed of acrylic acid, methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, isobutyl acrylate, isooctyl acrylate and the like as constituent monomers. Moreover, in the pressure-sensitive adhesive other than acrylic, a silicone-based pressure-sensitive adhesive may be used.

  The thickness of the adhesive component (adhesive component layer) used for the stretchable tape 3 affects the properties such as having the above-mentioned sustainability, and is selected so as to satisfy the properties. Therefore, the thickness of the adhesive component is particularly preferably 15 to 45 μm, more preferably 10 to 55 μm, and preferably 5 to 65 μm.

  Moreover, in order to give the property mentioned above, the thickness of the stretchable tape 3 combined with the base material and the adhesive component is selected so as to satisfy the property. Therefore, the thickness of the elastic tape 3 is particularly preferably 65 to 115 μm, more preferably 50 to 145 μm, and preferably 25 to 165 μm.

  For example, the thickness of the stretchable tape 3 using 75 μm as the base material of polyethylene 4 is 160 μm.

  As shown in FIGS. 1 (a) and 1 (b), the polyester 16 as the non-stretchable layer 15 has the same width in the short direction as the stretchable tape 3, and the edges of the same width match. Yes. Further, the non-stretchable layer 15 is shorter in the longitudinal direction than the stretchable tape 3, and is bonded only to the center in the longitudinal direction of the stretchable tape 3, and covers the surface of the stretchable tape 3 through the adhesive layer 6. .

  The polyester 16 which is the base material of the non-stretchable layer 15 is sufficient if it has sufficient non-stretchability to support the heel without being deformed while blinking along the shape of the heel at the time of sticking the heel.

  Further, the non-stretchable layer 15 is covered with a pressure-sensitive adhesive surface protective sheet 20 through a pressure-sensitive adhesive layer 17 on the surface opposite to the stretchable tape 3 side.

  Thus, the polyester 16 as the base material forms the non-stretchable layer 15 with the adhesive layer 17 provided between the adhesive surface protective sheets 20.

  The thickness of the polyester 16 as the substrate in the non-stretchable layer 15 is particularly preferably 15 to 30 μm, more preferably 10 to 50 μm, and preferably 5 to 75 μm.

  The thickness of the adhesive component (adhesive component layer) used for the non-stretchable layer 15 affects the properties such as having the above-mentioned sustainability, and is selected so as to satisfy the properties. Therefore, the thickness of the adhesive component is particularly preferably 15 to 45 μm, more preferably 10 to 55 μm, and preferably 5 to 65 μm.

  In addition, the thickness of the non-stretchable layer 15 including the base material polyester 16 and the pressure-sensitive adhesive component is selected so as to satisfy the above properties in order to provide the properties such as having the above-described sustainability. Therefore, the thickness of the non-stretchable layer 15 is particularly preferably 30 to 75 μm, more preferably 20 to 105 μm, and preferably 10 to 130 μm.

  For example, the thickness of the non-stretchable layer 15 using 23 μm as the thickness of the polyester 16 is 90 μm.

  Further, the material having the non-stretchable layer for preventing expansion and contraction may be non-woven fabric single-sided tape or OPP (oriented polypropylene) single-sided tape in addition to polyester 16.

  As shown in FIG. 1A, the release paper 26 as the adhesive surface protecting substrate 25 protects the adhesive layer 5 from dirt and the like. When the double wrinkle forming tape 1 is used, the release paper 26 is peeled off from the elastic tape 3.

  Moreover, as shown in FIG.1 (c), the release paper 21 as the adhesive surface protection seal 20 protects the adhesive layer 17 of the non-stretchable layer 15 from dirt. On the surface of the release paper 21, a large number of double wrinkle forming tapes 1 arranged in vertical and horizontal intervals are attached via an adhesive layer 17. Further, when the double wrinkle forming tape 1 is used, the double wrinkle forming tape 1 is separated from the release paper 21 to which a large number of double wrinkle forming tapes 1 are attached.

The material of the release paper 21 of the adhesive surface protection sheet 20 and the release paper 26 of the adhesive surface protection base material 25 is:
FEP (Fluoroethylene Propylene), PTFE (Polytetrafluoroethylene), PVF (Polyvinyl Fluoride), ECTFE (Chlorotrifluoroethylene-Ethyl Copolymer), Silicone, Fluoropolymer, etc. Any of the release treatment agents coated with may be used.

  Moreover, the thickness of the release paper 21 of the adhesive surface protection sheet 20 and the release paper 26 of the adhesive surface protection base material 25 is particularly preferably 0.5 to 10 μm, and more preferably 0.3 to 25 μm. The thickness is preferably 0.1 to 50 μm.

  Further, the surface of the release paper 26 as the adhesive surface protection substrate 25 (the surface in contact with the stretchable tape 3) is subjected to a surface treatment such as a mirror finish so as not to interfere with the adhesive layer 5 of the stretchable tape 3. Is preferred. By processing the release paper 26 to have a smooth surface, the release paper 26 can be easily peeled from the stretchable tape 3.

  Thus, the adhesive force between the stretchable tape 3 and the adhesive surface protective substrate 25 is weaker than the adhesive force through the adhesive layer 6 between the stretchable tape 3 and the non-stretchable layer 15.

  Further, the surface of the release paper 21 as the adhesive surface protective seal 20 (surface that contacts the non-stretchable layer 15) is subjected to surface processing such as mirror finishing so that it does not easily interfere with the adhesive layer 17 of the non-stretchable layer 15. Is preferred. By processing the surface of the release paper 21 to be smooth, the release paper 21 can be easily peeled from the non-stretchable layer 15. In FIG. 1A, the adhesive surface protective seal 20 and the adhesive layer 6 of the elastic tape 3 are separated, but the adhesive surface protective seal 20 and the adhesive layer 6 of the elastic tape 3 are in close contact with each other. It may be.

  Thus, the adhesion force between the non-stretchable layer 15 and the adhesive surface protective sheet 20 is weaker than the adhesion force via the pressure-sensitive adhesive layer 6 between the stretchable tape 3 and the non-stretchable layer 15.

Next, the size of the double fold forming tape 1 will be described with reference to FIG. 2A and 2B are views showing the size of the double fold forming tape, wherein FIG. 2A is a plan view and FIG. 2B is a developed perspective view.
The double fold forming tape 1 has an arcuate shape curved by an outer peripheral edge and an inner peripheral edge, and the central angle of the arc of the outer peripheral edge and the central angle of the arc of the inner peripheral edge are larger than the central angle of the arc of the outer peripheral edge. It has become. In the double fold forming tape 1, the arc of the outer peripheral edge is curved along the double line of the ridge.

  As shown in FIG. 2 (a), the length L1 in the longitudinal direction of the outer peripheral edge 3a of the stretchable tape 3 excluding the adhesive surface protective sheet 20 of the double fold forming tape 1 is, for example, 26 mm. The horizontal diameter is said to be around 26mm for both men and women over the age of 16. Thereby, 26 mm is suitable for the length of the longitudinal direction of the tape 1 for double wrinkle formation. Further, the length L4 in the longitudinal direction at the inner peripheral edge 3b of the elastic tape 3 is, for example, 24 mm.

  Moreover, as shown to Fig.2 (a), the length L2 of the longitudinal direction in the outer periphery 15a of the non-stretchable layer 15 shown with the dotted line of the tape 1 for double wrinkle formation is 23 mm. The length L3 in the longitudinal direction of the inner peripheral edge 15b of the non-stretchable layer 15 is 20 mm, and the length of the non-stretchable layer 15 is longer than the length L1 of the stretchable tape 3 corresponding to the lateral length of the eyes. Set to be shorter.

  Further, as shown in FIG. 2B, the double fold forming tape 1 includes a non-stretchable layer 15 made of polyester 16 which is difficult to stretch and stretches at the center of the surface of the release paper 21 as the adhesive surface protective sheet 20. The stretchable tape 3 formed by bonding and fixing polyethylene 4 to be bonded, and the release paper 26 as the adhesive surface protecting base material 25 are sequentially laminated.

  Moreover, as shown to Fig.2 (a), 1.2 to 2.0 mm is suitable for the width W1 of the tape 1 for double wrinkle formation. If the width of the double fold forming tape 1 is too narrow, the adhesive surface of the double fold forming tape 1 may be reduced in area, and sufficient adhesion and sufficient holding force to support the upper ridge may not be obtained. On the other hand, if the double wrinkle forming tape 1 is too wide, there may be a sense of discomfort when worn.

  Further, the stretchable tape (one base material) 3 and the non-stretchable layer (the other base material) 15 are configured to have the same width in the lateral direction, and the edges of the same width coincide.

  Moreover, as shown to Fig.2 (a), length L5 of the release paper 21 as the adhesive surface protection sheet 20 which stuck the double wrinkle formation tape 1 is 50 mm, and the width W2 of the adhesive surface protection sheet 20 is as follows. It sets so that it may become more than the length including the whole region of the short side direction of the elastic tape 3. FIG. On the other hand, as shown in FIG. 1 (c), when a plurality of double fold forming tapes 1 are placed on the adhesive surface protective sheet 20, for example, in FIG. 1 (c), the adhesive surface protective sheet 20. Is set to be 2 × L5 and the width is 10 × W2 or more.

  The size of the double fold forming tape 1 shown in FIG. 2 is an example, and the present invention is not limited to this.

  As described above, the double fold forming tape 1 has the pressure-sensitive adhesive layers 5 and 6 coated on both sides of the polyethylene 4 as the base material, and the polyester 16 as the non-stretchable layer 15 is attached to the center of the polyethylene 4 in the longitudinal direction. It is attached and fixed.

  Next, the usage method of the double wrinkle forming tape will be described with reference to FIGS. FIG. 3 is a diagram for explaining how to use the double wrinkle forming tape, and FIG. 4 is a diagram for explaining how to use the double wrinkle forming tape, showing the continuation of the method of use shown in FIG.

  The double wrinkle forming tape 1 has a surface on the side where polyethylene 4 which is a base material of the stretchable tape 3 is arranged on the eyeball side of the eyelid, and a side where polyester 16 as a base material of the non-stretchable layer 15 is arranged. Use so that the surface is opposite to the eyeball side of the eyelid.

  First, as shown to Fig.3 (a), the tape 1 for double wrinkle formation is cut | disconnected from the adhesive surface protection sheet 20 in which the tape 1 for double wrinkle formation was stuck. Thereafter, as shown in FIG. 3B, the release paper 26 is peeled off from the stretchable tape 3.

  Next, as shown in FIG. 3 (c), holding both ends of the release paper 21 of the adhesive surface protective sheet 20, with the double fold forming tape 1 stretched, a double fold is formed while matching the shape of the eyes. Along the line (in the case of the back double, inside the back double folds), the polyester 16 of the non-stretchable layer 15 is pressed and pasted so as to be positioned at the center of the left and right of the heel.

In addition, when affixing the elastic tape 3 to the eyelid, it is affixed so that the polyethylene 4 side is located on the skin side close to the eyeball. That is, as shown in the circle in FIG. 4B, the upper collar is supported by the polyester 16 as the non-stretchable layer 15, and the polyethylene 4 on the opposite side of the non-stretchable layer 15 is Make sure to stick it to the bag. This is the same regardless of whether the single is double or the back double.

  In this way, when used, the double fold forming tape 1 sandwiches both ends of the release paper 21 of the pressure-sensitive adhesive surface protection sheet 20 with fingers and uses the stretchable tape 3 covering the non-stretchable layer 15 of the double fold forming tape 1 as a fold. Affix it.

  Next, a state where the double fold forming tape is mounted on the ridge will be described with reference to FIG. 5A and 5B are diagrams for explaining the function of the double eyelid forming tape in the open eye state and the closed eye state. FIG. 5A shows the open eye state of the pupil, and FIG. 5B shows the closed eye state of the pupil. .

  When the eyes are open, that is, when the eyes are open, the eyelid is lifted up, the skin of the eyelid is contracted, and the skin is not pulled. That is, the eyelids contract and the skin of the eyelids is excessively loosened. For example, heavy heels such as thick heels, swollen heels, and back double heels may not support the upper heel and may hang down.

  As shown in FIG. 5 (a), the eyelids using the double eyelid forming tape lift the eyelids by supporting the upper eyelids covered with the polyester 16 as the non-stretchable layer 15 when the eyes are open. Function. 5A shows the state of the non-stretchable layer 15 when viewed from the front with the pupil open, and the arrows indicate the non-stretchable layer 15 affixed to the upper eyelid. The direction in which the weight of the heel is added to.

  At this time, the non-stretchable layer 15 of the double fold-forming tape attached to the upper heel is subjected to the weight of the heel by the loose fold skin, but the non-stretchability of the non-stretchable layer 15 Support the upper arm. Accordingly, the upper heel can be supported by heavy heels such as thick heels, swollen heels, and back double folds.

  On the other hand, as shown in FIG. 5 (b), when the eyelid is closed, that is, when the eye is closed, the skin of the eyelid is in a state of extending with the pin and the skin is stretched.

  In addition, as described above, the upper eyelid on which the double eyelid-forming tape is attached has an average time of blinking of 100 to 150 milliseconds, and it is performed for an adult 10 times or more per minute, and In combination with the fact that the eyelid is the thinnest part of human skin, the upper eyelid requires a very delicate movement. It is required to prevent the application of a force that hinders the movement of the upper eyelid.

  The double fold forming tape 1 shown in FIG. 5B shows the state of the stretchable portion 18 of the stretchable tape 3 when viewed from the front with the eyelid closed, and the arrows indicate the direction in which the stretchable portion 18 is pulled. . At this time, the stretchable portion 18 of the stretchable tape 3 is stretched by being pulled to the left and right as indicated by the arrows in accordance with the skin of the extended eyelids. Thus, the expansion / contraction part 18 which consists of the polyethylene 4 which is a base material which expands-contracts expands-contracts according to a motion of a collar.

  Thereby, the floating of both ends of a tape and a sense of incongruity can be eased. Further, since the eye can be completely closed when the eyelid is closed, it is possible to prevent small eyelids around the eyes such as the corners of the eyes and the eyes, dry eyes (drying of the eyes), and the like.

  Next, an example in which the double wrinkle forming tape is mounted in the back double will be described with reference to FIGS. The double fold forming tape of the present invention is not limited to the back fold, and can be used when a single fold is made into a double fold.

  FIG. 6 is a cross-sectional view illustrating a state in which the double fold forming tape is mounted in the back double in a plan view, and FIG. 6 (a) is a double fold forming tape using only polyester as an elastic tape. Fig. 6 (b) is a cross-sectional view showing a state of being attached to the bag. Fig. 6 (b) shows a double fold-forming tape in which polyethylene, which is a non-stretchable layer, is fixed to the center via an adhesive layer. It is sectional drawing which shows the state which carried out.

  As shown in FIG. 6 (a), the double wrinkle forming tape using only the polyester 70 as the stretchable tape is attached along the curve of the back double 52 of the wrinkle 51, so both ends of the polyester 70 which is a hard material. May float during use due to the restoring force and peel off.

  On the other hand, as shown in FIG. 6 (b), the double fold forming tape 1 in which polyethylene 4 is used for the stretchable tape 3 and the polyester 16 as the non-stretchable layer 15 is fixed to the center through the adhesive layer is polyester. It acts to absorb 16 restoring forces throughout the polyethylene 4.

  Therefore, when the soft polyethylene 4 is in close contact with the back double 52 of the heel 51, both ends are not lifted and peeled off during use, like a double heel forming tape using only the polyester 70 for the stretchable tape 3, It can be used for a long time.

  Further, since the stretchable portions 18 on both sides of the non-stretchable layer 15 are made difficult to be inserted into the back, the both ends of the polyester 4 may float during use due to the holding force (fixation) of the stretchable portion 18 and peel off. More prevented.

  FIG. 7 is a front view for explaining a comparison between the conventional double fold forming tape and the double fold forming tape according to the present invention, and FIG. 7 (a) is a conventional double fold formation using polyester. FIG. 7 (b) shows a state in which the wrinkles are mounted by the double wrinkle forming tape of the present invention.

  As shown to Fig.7 (a), since the conventional double wrinkle formation tape using the polyester 70 uses the polyester 70 with high compressive strength, it can support the wrinkles to cover. As shown in FIG. 7A, the lateral length Le of the eye 50 is, for example, 26 mm. However, since the hard polyester 70 having the same length as the lateral length of the eye 50 is attached, the heel, particularly the both ends of the eye, may feel uncomfortable.

  A research report on eyelid morphology entitled “Japanese eyelid morphology and upper eye lift muscle function” is described in the clinical report of the May 1974 issue of the medical journal Clinical Ophthalmology. According to "Japanese eyelid morphology and upper eye lift muscle function", the lateral diameter of Japanese eyes is reported to be around 26 mm for both men and women over the age of 16.

  As shown in FIG. 7 (b), in the double fold forming tape 1 of the present invention, the polyethylene 4 of the stretchable tape 3 and the polyester 16 of the non-stretchable layer 15 are fixed. Based on the research report, the length L2 in the longitudinal direction of the non-stretchable layer 15 is 23 mm, which is 26 mm or less of the length Le in the lateral direction of the eye 50.

  As described above, the length L2 in the longitudinal direction of the non-stretchable layer 15 is set to 23 mm based on the research report, so that the size of the uncomfortable polyester can be reduced. Can be obtained. In addition, it is possible to support the folds covered by the back double. Furthermore, by providing polyethylene, which is a flexible material, on the left and right sides, it is possible to change the method of attachment according to the shape of the eyes that differ from each other (the shape of the eyelids) and to form natural and beautiful double eyelids. .

  Further, by interposing the polyethylene 4 that is a flexible material between the polyester 16 and the collar 51, the restoring action of the polyester 16 can be relaxed.

  Thus, the polyethylene 4 of the stretchable tape 3 and the polyester 16 of the non-stretchable layer 15 are fixed via the adhesive layer 6, and the adhesion between the polyethylene 4 of the stretchable tape 3 and the polyester 16 of the nonstretchable layer 15 is fixed. Has become a big thing. Thereby, the part of the polyethylene 4 covered with the polyester 16 is integrated with the polyester 16 to form the non-stretchable layer 15.

  The length of the non-stretchable layer 15 in the longitudinal direction is equal to or less than the length of the eyes 50 in the lateral direction. Thereby, it is possible to reduce the size of the polyester which feels uncomfortable. In addition, it is possible to support the folds covered by the back double.

  As described above, the double wrinkle forming tape includes two layers of strip-like base materials bonded to each other, and one base made of polyethylene is made of a material that is more flexible than the other base made of polyester. The other base material made of polyester is shorter in the longitudinal direction than the one base material made of polyethylene, and is bonded to only the center in the longitudinal direction of the one base material made of polyethylene. The base material is made of a material that expands and contracts by the movement of the heel, and the other base material made of polyester is made of a material that does not expand and contract by the movement of the heel.

  Thereby, the double wrinkle forming tape of the present invention can support heavy wrinkles (heavy wrinkles) such as thick wrinkles, swollen wrinkles, and deep double wrinkles. Further, it can be used for a long time without peeling off from the wrinkles for a long time.

  As described above, the double fold forming tape of the present invention has the following effects. The double wrinkle forming tape includes a two-layered strip-shaped base material bonded to each other, and one base material (stretchable tape) is composed of a material (more flexible material) that expands and contracts by the movement of the scissors. Since the base material (non-stretchable layer) is made of a material that does not expand or contract depending on the movement of the eyelids (a material that is less flexible than one base material), The other base material that is not supported supports the overlying eyelids, and in the closed eye state, the base material that expands and contracts by the movement of the eyelids expands and contracts according to the skin of the extended eyelids. The double wrinkle forming tape using only a material that does not expand and contract as in the past feels a tingling sensation at both ends of the wrinkle. In the double wrinkle forming tape of the present invention, since the stretchable material is disposed at both ends in the longitudinal direction, the material disposed at both ends of the scissors expands and contracts due to the motion of the scissors. Can be resolved. Thereby, the user does not feel uncomfortable and can form a natural double fold.

  In addition, the double fold forming tape of the present invention comprises two layers of strip-like base materials bonded to each other, and one base material (elastic tape) is a material that is more flexible than the other base material (non-elastic layer) The other base material is shorter in the longitudinal direction than the one base material, and is bonded to only the central portion in the longitudinal direction of the one base material. Because it is configured, it becomes possible to relax the restoring action of the other base material that does not expand and contract by laminating one flexible base material, and the double wrinkle forming tape using only a hard base material Thus, both ends do not float and peel off during use, and can be used for a long time.

  Furthermore, the double wrinkle forming tape of the present invention is composed of only one base material whose both ends in the longitudinal direction expand and contract, and therefore, the other base material that does not expand and contract by holding (fixing) both ends of one base material. It is further prevented that both ends are lifted and peeled off during use by the restoring force.

  In addition, the double wrinkle forming tape of the present invention has an arcuate shape formed by the outer peripheral edge and the inner peripheral edge, the arc of the outer peripheral edge is curved along the double line of the reed, and further, Since one material made of softer material is arranged at both ends of the eyes, etc., because one material expands and contracts due to the movement of the eyelid, it can form a thin double line and create a natural impression .

  In addition, since the double wrinkle forming tape of the present invention does not expand and contract, it is possible to reduce the size of the substrate that feels uncomfortable, so that it is possible to relieve the discomfort of wrinkles. In addition, by providing flexible base materials on the left and right sides of the base material that do not expand and contract, the method of application is changed according to the shape of the eye that is different from each other (the shape of the eyelids), forming a natural and beautiful double eyelid. Is possible.

  Further, the double wrinkle forming tape of the present invention can be supported by lifting the wrinkles covered by the back double by providing a non-stretchable layer at the center in the longitudinal direction of the stretchable tape. It is possible to form a thin double line (a double line) with one material made of a softer material at both ends of the eye.

  Hereinafter, a comparison between the prior art document discovered in the prior art search by the applicant and the present invention will be described.

  Patent Document 1 (Act No. 3119162), Patent Document 2 (Act No. 3154139), Patent Document 4 (Japanese Patent Laid-Open No. 2014-54519) and Patent Document 5 (Japanese Patent Laid-Open No. 2009-22592) The material is polyester or polypropylene.

  However, the curved eyelids of a swelling East Asian with a lot of fat may cause the double wrinkle-forming tape to float off and peel off from the corners of the eyes and both ends of the eyes when applied for a long time.

  As a result, there may be a problem in use such that the floating part of the hard base material is tinged.

  From the viewpoint of the material, the double fold forming tape using only a hard material such as polyester as the base material of the stretchable tape may be lifted at both ends by the restoring force during wearing and use, and may be peeled off.

  The double wrinkle forming tape of the present invention includes two layers of strip-like base materials bonded to each other, one base material is made of a material more flexible than the other base material, The base material is shorter than the base material, and is bonded only to the central portion of the base material in the longitudinal direction.

  The present invention, by providing a non-stretchable layer at the center in the longitudinal direction of the stretchable tape, it can support while lifting the eyelids covered in the back double, and further, both ends of the eyes, such as the corners of the eyes and the eyes, A thin double line (a heavy line) can be formed by one of the softer materials.

  In addition, the double wrinkle forming tapes of Patent Document 1 and Patent Document 2 use a hard material (polyester or polypropylene) having a width of about 1.5 mm to 2.0 mm. However, since the members of Patent Document 1 and Patent Document 2 are made of a hard material, there is a possibility that the members cannot move flexibly due to blinking or the like.

  In addition, since the double wrinkle-formed products in Patent Document 4 and Patent Document 5 do not use the shrinkage of the tape material, in the case of a hard material (polyester or polypropylene) made of a non-stretchable strip material, it is bent due to the blinking movement of the wrinkles. There is a risk that it will not be possible to adhere to the upper arm for a long time.

  Moreover, the double fold forming tape using only a hard material such as polyester as the base material of the stretchable tape may be lifted at both ends by a restoring force during wearing and use, and may be peeled off.

  The double wrinkle forming tape of the present invention comprises two layers of strip-like base materials bonded to each other, and one base material (elastic tape) is made of a material (more flexible material) that expands and contracts by the movement of the eyelids. The other base material (non-stretchable layer) is made of a material that does not expand or contract depending on the movement of the eyelids (a material that is less flexible than the other base material). The other base material that is not supported supports the overlying eyelid, and in the closed eye state, the base material that expands and contracts by the movement of the eyelid expands and contracts according to the skin of the extended eyelid. The double wrinkle forming tape using only a material that does not expand and contract as in the past feels a tingling sensation at both ends of the wrinkle. In the double wrinkle forming tape of the present invention, since the stretchable material is disposed at both ends in the longitudinal direction, the material disposed at both ends of the scissors expands and contracts due to the motion of the scissors. Can be resolved. Thereby, the user does not feel uncomfortable and can form a natural double fold.

  Thus, since the double wrinkle forming tape of the present invention does not use only a hard material, it can be used for a long time without giving a sense of incongruity to the wrinkle. It has characteristics that are not available.

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
