Description

Patch material and its patch

The present invention relates to a patch and its patch.

¡When the skin ages, wrinkles and looseness occur in the skin. For women, wrinkles and slack in the skin may cause a significant decrease in quality of life (QOL). In response to the desire to keep youthful and firm skin forever, in order to keep the QOL high, there is a need for means to efficiently correct skin slack and wrinkles.

For example, Patent Document 1 discloses an adhesive material in which one end of a support is affixed to the skin portion of the lower jaw and the other end of the support is affixed to the skin portion behind the ear. When this patch is affixed, the skin on the lower face is pulled upward, the skin loosened on the lower face is corrected, and wrinkles can be flattened.

JP 2002-241222 A

However, the conventional patch has a small effect of correcting the loose skin, and it is difficult to sufficiently flatten deep constriction lines and marionette lines. Moreover, an unnatural depression often occurs on the skin to which the conventional patch is stuck.

Therefore, an object of the present invention is to provide a patch material that has a large effect of correcting wrinkled and loosened skin and is unlikely to cause unnatural depressions in the skin. Furthermore, the subject of this invention is providing the sticking tool which can stick the above-mentioned sticking material to skin appropriately.

The present inventor has examined problems in pasting a conventional patch. In the loose skin, the epidermis becomes flat, the dermis layer loses elasticity and thins, and as a result, the area expands in all directions. For this reason, it is considered that the loose skin cannot be corrected over a wide range if the conventional skin patch is applied and the loose skin is pulled in a single direction. In addition, the conventional adhesive material requires an advanced technique for applying the adhesive material while pulling the adhesive material in an appropriate single direction at an appropriate strength at the time of application. If a person who is not skilled in handling the patch is affixed, it is considered that a part of the skin is strongly pulled locally, resulting in an unnatural depression.

Based on the above idea, the present inventor applied a part of the patch so as to hold the loose skin part in a state of being pulled in one direction, and then put the loose skin part in another direction. We have developed a patch that can be applied to other parts of the patch to hold it in a towed state. As a result, it was found that the effect of correcting wrinkled and loosened skin was markedly superior to conventional adhesives, and that it was possible to provide an adhesive that was easy to apply so as not to cause unnatural depressions in the skin. .

That is, in order to achieve the above-mentioned problem, a patch according to the present invention is a patch having an elastic film-like support and an adhesive layer provided on one surface of the support, The patch material includes a base portion having one end portion and the other end portion, a first extension portion extending from the other end portion, and a direction different from the direction in which the first extension portion extends. A second extension part extending from the end part, and the base part is attached to at least a part of the loose skin part when the adhesive material is applied, and the one end Is pulled toward the first extension part, and is pulled toward the second extension part in a direction different from the direction from the one end part toward the first extension part. It is characterized by that.

Alternatively, the patch is a patch provided with an elastic film-like support and an adhesive layer provided on one surface of the support, and the patch has one end and the other end. A first extension portion extending from the other end portion, and a second extension extending from the other end portion in a direction different from the direction in which the first extension portion extends. And at least a portion.

When the sticking material is stuck, one or more parts selected from the group consisting of the one end part, the first extension part, and the second extension part are muscle tissue, tendon tissue, and It may be characterized by being affixed to at least a part of the skin portion fixed to the bone tissue via one or more kinds of tissues selected from the group consisting of cartilage tissues.

When this patch is affixed, the base portion is affixed to at least a part of the loose skin part, and the loose skin part is between the spine line and the front of the ear. And the fixed skin portion may be a skin portion in front of the ear.

In the present patch, when the base is applied, the base is attached to at least a part of the loose skin part, and the loose skin part is between the marionette line and the front of the earlobe. And the fixed skin portion may be a skin portion of the front of the earlobe.

In the present patch, when the base is applied, the base is attached to at least a part of the loose skin part, and the loose skin part is between the eye bag and the temple of the lower eyelid. One or more skin parts selected from the group consisting of a part and a skin part between the back of the nose and the temple. The fixed skin part may be a skin part of the temple.

When the sticking material is stuck, the base is stuck to at least a part of the loose skin part, the loose skin part is a skin part between eyebrows, and the fixed skin part May be characterized by being one or more skin parts selected from the group consisting of the skin part of the back of the nose and the skin part of the hairline of the frontal head.

In this patch, the support has a thickness of 6 to 50 μm, the support has a 20% tensile strength of 0.1 to 3 N / cm, and the pressure-sensitive adhesive layer has a thickness of 5 to 100 μm. Can be characterized.

In the present patch, when the thickness of the support is w, the ten-point average roughness Rz of the other surface of the support is 6 μm ≦ Rz ≦ 40 μm and Rz ≦ w. It can be.

Further, the sticking tool includes a frame surrounding the sticking material, one end holding means attached to the frame to hold the one end, and a first attached to the frame to hold the first extension part. An extension portion holding means; and a second extension portion holding means attached to the frame and holding the second extension portion.

The patch material according to the present invention including the above-described configuration includes at least a shape in which the first extension portion and the second extension portion extend in different directions from one end portion of the base portion. With this shape, when properly affixed, the base is affixed to at least a part of the loose skin when the affixing material is affixed and pulled toward the first extension from one end. And a state of being pulled toward the second extending portion in a direction different from the direction from the one end portion toward the first extending portion. At this time, since the base portion is affixed to at least a part of the slack skin portion, the direction toward the first extension portion and the second extension portion in a direction different from this direction are the same as the base portion. And being pulled in a plurality of directions. Furthermore, in the direction between the first extending portion and the second extending portion from the slack skin portion, the pulling force in the direction toward the first extending portion described above, and the second extending portion described above. Since the traction force in the direction is combined, the slack skin portion at this time is held in a state of being pulled in the direction between the first extension portion and the second extension portion. When the loose skin is held in a state where it is pulled in multiple directions, it expands over a wider area than when the conventional patch is applied and the loose skin is pulled in a single direction. It is possible to appropriately pull the excess skin, that is, to loosen the skin over a wide range.

¡If the loosening of the skin is resolved over a wide area, the wrinkles that have occurred near the loosened skin will be flattened efficiently. For example, if the base of this patch is applied to at least a part of the skin part of the loose cheek and the looseness of the skin part is corrected, the deep constriction lines and marionette lines near the skin part are efficiently obtained. It becomes flat and shallow.

Also, compared to the case where the conventional patch is applied and the skin is pulled in a single direction, when the patch is applied as described above, the excessive skin that has been expanded over a wide range is pulled in multiple directions. Therefore, it is difficult for unnatural depressions to occur on loose skin. Furthermore, since this sticking material comprises at least a first extension part and a second extension part, the traction force locally concentrates on only one extension part when attached. That can be avoided. For this reason, compared with the case where the pasting material is pasted and the skin is pulled in a single direction, when the present pasting material is pasted, the skin part to which the first extension portion is pasted, Unnatural depressions are unlikely to occur in the skin part to which the extension is attached.

[Embodiment 1]
As shown to Fig.1 (a), the patch (1aL, 1aR) which concerns on Embodiment 1 is provided with the support body 8a and the adhesive layer 9a. Furthermore, as shown to Fig.2 (a), a patch (1aL, 1aR) is a base part (2aL, 2aR), a 1st extension part (3aL, 3aR), and a 2nd extension part by the shape. (6aL, 6aR).

The adhesive material 1aR for the right side of the face and the adhesive material 1aL for the left side of the face are a pair of left and right sets for the person to be applied so that it can be applied to the right side and the left side of the face. The patch 1aL and the patch 1aR have the same configuration except that their shapes are mirror image symmetric. Hereinafter, although the patch 1aL will be described, the description is the same for the patch 1aR.

As shown in FIG. 1 (a), the patch 1aL has a laminated structure in which a film-like support 8a has one surface 11a and another surface 10a, and an adhesive layer 9a is provided on the one surface 11a. The pressure-sensitive adhesive layer 9a is provided with a skin contact surface 13a facing the one surface 11a of the support 8a. In the part where the skin contact surface 13a is in contact with the skin, the patch 1aL is stuck to the skin.

The support 8a is made of, for example, a resin composition having one or more elasticity selected from the group consisting of polyurethane, polyacrylic ester resin, polyisobutylene, polyvinyl acetate, and the like. Since the support body 8a comprised by this resin composition has moderate elasticity, it is hard to tear when the patch 1aL is pulled. The support 8a is preferably thin and flexible. If the support 8a is thin, when the patch 1aL is affixed to the skin, the affixed person is less likely to feel discomfort in the skin. If the support 8a is flexible, the affixed patch 1aL easily expands and contracts following the movement of the skin, and is difficult to peel off from the skin.

The pressure-sensitive adhesive layer 9a is selected from the group consisting of an acrylic pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, a silicon-based pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, and the like, which are used in medical patches and are dermatologically acceptable. It is comprised by 1 or more types of adhesives. In order to suppress irritation to the skin, the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 9a is preferably an acrylic pressure-sensitive adhesive. The acrylic pressure-sensitive adhesive has, for example, one or more compounds selected from the group consisting of acrylic acid, acrylic acid esters having 8 to 10 carbon atoms, hydroxyethyl acrylate, and hydroxyethyl acrylamide as a main monomer, vinyl acetate, And a pressure-sensitive adhesive composition obtained by polymerizing one or more compounds selected from the group consisting of alkoxyalkyl esters as a comonomer. A gel-like copolymer acrylic pressure-sensitive adhesive containing 5 to 50% of a liquid having a melting point of 10 ° C. or higher and a boiling point of 120 ° C. or higher and cross-linked to the pressure-sensitive adhesive composition constitutes the pressure-sensitive adhesive layer 9a. It is more preferable that the pressure sensitive adhesive is used.

As shown in FIG. 2 (a), the patch 1aL is U-shaped as a whole. The base 2aL has a substantially rectangular outer shape, and has one end 4a and the other end 12a. The first extending portion 3aL has a tongue-like outer shape and extends from the other end portion 12a. The tongue-like tip portion of the first extension portion 3aL is defined as a first tip portion 5a. The second extending portion 6aL has a tongue-like outer shape, and extends from the other end portion 12a in a direction different from the direction in which the first extending portion 3aL extends. The tongue-like tip portion of the second extending portion 6aL is defined as a second tip portion 22a.

In addition, in this invention, the extension part pasted first is made into the 1st extension part among several extension parts, and the extension part stuck next after the 1st extension part is stuck Is the second extension. Moreover, in the patch 1aL, the extension part stuck on the lower side when stuck on the body is the first extension part 3aL, and the extension part stuck on the upper side is the second extension part 6aL. Is preferred. In this case, the slack skin portion can be corrected while being pulled so as to be gradually raised from the lower side toward the upper side.

In the present invention, the substantially quadrangular shape is an external shape such as a quadrangle, a part of the external shape corresponding to the side of the quadrangle includes a curved portion, and a rounded portion is provided at a portion corresponding to the corner of the quadrangle, Since some of the outer shapes are connected to and integrated with the extension, some corners and sides are not clear. For example, in the patch 1aL, the base 2aL has an outer shape like a quadrangle, and has two corner portions 18a sandwiching one side 19a of the quadrangle. One side 19a is curved and two corner portions 18a are rounded. Moreover, the concave-shaped concave vertex 20a formed between the 1st extension part 3aL and the 2nd extension part 6aL of the patch 1aL is a point which is on the opposite side of the one side 19a in a square shape. However, since the peripheral portion of the concave apex 20a is connected to and integrated with the respective root portions 23a of the first extension portion 3aL and the second extension portion 6aL, the base portion 2aL has the entire opposite side of the one side 19a, The two corner portions 21 sandwiching the opposite side do not have a square corner or a clear outline as its periphery. Assuming, as a whole, the line passing through the concave vertex 20a and crossing the integrated portion connected to the respective root portions 23a of the first extension portion 3aL and the second extension portion 6aL, It can be said that the two corners 21 sandwiched between can be hypothesized and the base 2aL has a quadrangular shape.

Further, the different direction in the present invention means that when the patch has two extending portions, the extending direction of each extending portion is at a different angle within a range of 10 to 90 °. It means being. Alternatively, the different direction in the present invention means that when the patch has three or more extending portions, the directions in which the extending portions extend differ from each other within a range of 5 to 180 °. It means that you are facing. Thus, if the extending directions of the extending portions are different, the base portion and the skin portion to which the base portion is applied are pulled in the direction between the extending portions if the sticking material is appropriately applied. Therefore, it is possible to efficiently eliminate skin slack. In the patch 1aL, for example, the outer shapes of the first extension portion 3aL and the second extension portion 6aL are as equidistant as possible with respect to the two sides extending side by side in the longitudinal direction of the tongue. A virtual straight line formed by connecting a plurality of straight lines, and an intersection formed by extending these two virtual straight lines, the crossing angle is 20 to 40 °. That is, in the patch 1aL, the extending direction of the first extending portion 3aL and the extending direction of the second extending portion 6aL are 20 to 40 ° open.

The shortest distance from one side 19a to the concave vertex 20a is the horizontal length of the base 2aL, and the shortest width shown when the width of the base 2aL is measured in a direction orthogonal to the horizontal direction is the vertical direction of the base 2aL. Of length. The dimension of the base 2aL is, for example, 30 mm long × 20 mm wide. Further, a line perpendicular to the horizontal direction passes through a bisector of the horizontal length of the base portion 2aL, and a portion of the base portion 2aL that is closer to the side 19a than the virtual line is The portion 4a and the portion of the base 2aL that is closer to the concave vertex 20a than the virtual line is referred to as the other end 12a. The one end portion 4a is composed of one side 19a, two corner portions 18a, and a peripheral portion of the base portion 2aL having a substantially square shape. The other end portion 12a includes a concave vertex 20a, two corner portions 21 sandwiching the opposite side of the one side 19a described above, and a peripheral portion thereof.

The procedure of the sticking method of the patch 1aL will be described. First, for example, the first tip 5a is pulled in a state where the one end 4a and the first tip 5a of the patch 1aL are simultaneously picked by the fingertips of different hands. For this reason, as shown to Fig.3 (a), the patch 1aL will be in the state pulled in the direction which goes to the 1st front-end | tip part 5a from the one end part 4a. In this state, only one end 4a is stuck on at least a part of the slack skin portion 41. Next, as shown in FIG. 3B, while pulling the base portion 2aL and the first extension portion 3aL in the direction from the one end portion 4a toward the first tip portion 5a, the other end portion 12a, the root portion 23a, It sticks in order of the 1st front-end | tip part 5a of the 1st extension part 3aL. Finally, as shown in FIG. 3 (c), while pulling the second tip 22a of the second extension 6aL in a direction different from the direction in which the first extension 3aL is pulled while pulling, the other It sticks in order of the edge part 12a, the base part 23a, and the 2nd front-end | tip part 22a of the 2nd extension part 6aL.

The sticking material 1aL when stuck by the above procedure is stuck on at least a part of the skin portion 41 where the base 2aL is loosened. Further, the base portion 2aL and the first extension portion 3aL are pasted in a state of being pulled in a direction from the one end portion 4a toward the first tip portion 5a of the first extension portion 3aL. Further, the base portion 2aL and the second extension portion 6aL are arranged such that the second tip portion of the second extension portion 6aL is in a direction different from the direction in which the first extension portion 3aL is applied while being pulled from the one end portion 4a. It is stuck in a state of being pulled in the direction toward 22a.

In addition, as shown in FIG. 4C, the body includes a skin portion fixed to the bone tissue via at least one kind of tissue selected from the group consisting of muscle tissue, tendon tissue, and cartilage tissue ( (Hereinafter referred to as “fixed skin part”). If the base 2aL and the first extension 3aL are attached in a state where they are pulled in the direction from the one end 4a toward the first tip 5a as shown in FIG. At least a part of the slack skin portion 41 is held in a state of being pulled from the fixed skin portion 43 on the extension line opposite to the direction toward the fixed skin portion 45 in the pulling direction. The

Next, as shown in FIG. 3C, when the second extension 6aL is applied while being pulled in a direction different from the direction in which the first extension 3aL is applied while being pulled, the direction opposite to the pulling direction is obtained. From another fixed skin portion 44 that is on the extension of and near the fixed skin portion 43 to another fixed skin portion 46 that is in this traction direction and slightly away from the fixed skin portion 45 Toward, at least a part of the loose skin 41 is held in a pulled state. Further, the loosened skin portion 41 is fixed by combining the pulling direction of the first extending portion 3aL to the first tip portion 5a and the pulling direction of the second extending portion 6aL to the second tip portion 22a. Held in a wide range of directions to a further fixed skin portion 47 between the fixed skin portion 45 and the other fixed skin portion 46.

For this reason, when the adhesive material according to the present invention is applied while pulling the slack skin part in a plurality of directions as described above, the base portion is compared with the case of applying the adhesive material while pulling the conventional adhesive material in a single direction. Not only the affixed skin part but also the surplus skin that has spread over a wide area around the skin part can be pulled and corrected appropriately. Furthermore, when the skin looseness is eliminated over a wide area, wrinkles that have occurred near the loose skin portion are efficiently flattened.

Moreover, this sticking material is stuck through the step of sticking while pulling the first extension part and the step of sticking while pulling the second extension part. Since it is applied through multiple steps, the direction of pulling the slack skin portion can be adjusted in order, and the strength of the traction force that reaches each of the first extension portion and the second extension portion can be dispersed sequentially. For this reason, even for those who are not skilled in handling conventional patch materials, it is easy for traction force to concentrate locally on only one extension part when applying this patch material. Therefore, it is easy to apply so that an unnatural depression does not occur in the skin part to which each extending part is attached. Further, as shown in FIG. 3 (c), the present adhesive material sequentially distributes the strength of the traction force between the first extension part and the second extension part, as shown in FIG. 3 (c). Since the skin that has slackened in a wide range of directions between the skin and the skin can be pulled more strongly, it is easy to apply the skin so that the skin with the slack corrected has a natural appearance.

Therefore, according to the present invention, it is possible to provide a patch that has a large effect of correcting wrinkled and loosened skin and that is unlikely to cause unnatural depressions in the skin. For this reason, the patch according to the present invention is preferably used as a patch for skin correction. More preferably, it is used as a patch for correcting senile facial features to correct senile facial features into youthful and natural facial features. The effect of the present invention is that the base portion is attached to at least a part of the loosened skin portion while pulling the base portion and the first extension portion in the direction from the one end portion toward the first tip portion of the first extension portion. 1st tip part of the 1st extension part is stuck, and then it sticks while pulling the 2nd tip part of the 2nd extension part in a direction different from the direction stuck while pulling the 1st extension part. It is further demonstrated by taking the sticking method.

The patch 1aL preferably includes a release paper 14a that covers the skin contact surface 13a as shown in FIG. 1 (b). The skin contact surface 13a is protected until the release paper 14a is peeled off. More preferably, the release paper 14a is made of a material that can be easily peeled off from the skin contact surface 13a with a small force. Examples of the material of the release paper 14a include, for example, a paper that has been siliconized on one side, a paper and polyolefin thin film that have been bonded together, and a silicon film that has been siliconized, or a polyester film that has been siliconized. What you gave. Further, it is preferable that the release paper 14a is provided with a knob 16 that protrudes from a portion covering the skin contact surface 13a because it is easy to peel off.

When the patch 1aL includes the release paper 14a, as shown in FIGS. 1B and 2A, the release paper 14a is preferably provided with a cut (half cut) 17a. The cut 17a is provided on the release paper 14a so as to cross the respective root portions 23a of the first extension portion 3aL and the second extension portion 6aL shown in FIG. Further, the cut line 17a is provided in a different direction for each root part 23a. Alternatively, in place of the cut line 17a, a cut line 24a that crosses all the root portions 23a in the same direction may be provided in order to simplify the manufacturing process. As shown in FIGS. 1B and 2A, the release paper 14a provided with the cut line 17a or the cut line 24a includes a base covering portion 25a that covers the skin contact surface 13a of the base 2aL, and a first tip. The first tip portion covering portion 26a that covers the skin contact surface 13a of the portion 5a and the second tip portion covering portion that covers the skin contact surface 13a of the second tip portion 22a (not shown in FIG. 1B). 27a (not shown in FIG. 1B).

The procedure of the sticking method is demonstrated about the patch 1aL in case the cut 17a or the cut 24a is provided in the release paper 14a. As shown in FIG. 4A, the base covering portion 25a of the release paper 14a is peeled off. Since the first tip portion covering portion 26a and the second tip portion covering portion 27a are separated from the base portion covering portion 25a by the cut line 17a or the cut line 24a, they remain on the skin contact surface 13a. For this reason, when sticking the patch 1aL, it is easy to pull the first tip portion 5a and the second tip portion 22a with a fingertip.

Next, for example, the one end portion 4a and the first tip portion 5a are picked by the fingertips of different hands and pulled in the direction from the one end portion 4a toward the first tip portion 5a. While pulling in this way, as shown in FIG. 4 (b), only one end 4a is affixed to at least a part of the slack skin portion 41. Subsequently, while pulling the base 2aL and the first extension 3aL in the direction from the one end 4a toward the first tip 5a of the first extension 3aL, the other end 12a and the root 23a are attached in this order. . At this time, if the first tip portion 5a is picked and pulled by a fingertip or the like, the base portion 2aL and the first extension portion 3aL are pulled in the direction from the one end portion 4a toward the first tip portion 5a of the first extension portion 3aL. Can keep the state.

Next, as shown in FIG. 4C, the first tip portion covering portion 26a is peeled off, and the base portion 2aL and the first extending portion 3aL are pulled in the direction from the one end portion 4a toward the first tip portion 5a. Meanwhile, the first tip 5a of the first extension 3aL is pasted. Finally, the second tip portion covering portion 27a is peeled off, and the second tip portion 22a is pulled from the one end portion 4a in a direction different from the direction in which the first extension portion 3aL is attached while being pulled. It sticks in order of the edge part 12a, the base part 23a, and the 2nd front-end | tip part 22a of the 2nd extension part 6aL.

As described above, when the patch 1aL includes the release paper 14a provided with the cut line 17a or the cut line 24, even if the base cover part 25a is peeled as shown in FIG. The portion 26a and the second tip portion covering portion 27a remain. For this reason, as shown in FIG. 4B, when the one end 4a is affixed to at least a part of the slack skin portion 41, the first tip portion 5a and the second tip portion 22a are mistakenly attached to the skin. You can avoid that. Moreover, since the 2nd front-end | tip part covering part 27a remains when pulling the 1st extension part 3aL, it can avoid that the 2nd front-end | tip part 22a adheres to skin accidentally. Thus, when sticking material 1aL is provided with release paper 14a provided with cut 17a or cut 24a, the person who sticks settles each procedure shown in Drawing 4 (a), (b), and (c). Can be done one by one. For this reason, it becomes easier to apply the skin so that the slack has been corrected so that the skin has a natural appearance.

The present inventor examined the cause of wrinkles and looseness in the skin from an anatomical point of view in order to correct the loosened skin portion 41 more efficiently. The fixed skin portion 42 described above is maintained in a state where the position on the body is fixed even when the skin ages. As the fixed skin portion 42, for example, in the human head 51 shown in FIG. 4C, the hairline portion 52 of the frontal head hair, the eyebrow 53, the inner eye angle 54, the outer eye angle 55, the front nose Examples thereof include skin portions covering the spines 56, the heels 57, the external auditory canal 58, and the like, and these skin portions are firmly bonded to the bone tissue through muscle tissue, tendon tissue, cartilage tissue, and the like. Examples of the fixed skin portion 42 include the skin where the constriction line 59 is generated and the surrounding skin portion 60, and these skin portions slowly move to the maxilla and gingival portion in the oral cavity via facial muscles. Is supported and fixed.

On the other hand, the position of the loose skin portion 41 is not fixed, and the skin area is increased due to aging. The surplus skin with an increased area hangs down due to gravity with the fixed skin portion 42 as a support site, thereby causing wrinkles and slack in the skin. As a result, it is considered that a human whose facial skin is aged is transformed into a senile facial appearance.

The conventional patch is not a shape or size that is easy to stick to the skin part 42 to which the part is fixed or its peripheral part, and the skin fixed based on an anatomical viewpoint at the design stage. It is considered that the position of the portion 42 is not considered. Moreover, the skin part which is not fixed from an anatomical viewpoint moves frequently with contraction of muscle tissue in daily life. For example, a skin portion that is not fixed from the anatomical point of view of the face frequently moves greatly due to a change in facial expression. In many cases, the conventional patch is applied so that the slack skin portion 41 is pulled toward an unfixed skin portion from an anatomical viewpoint, and the slack skin portion 41 is pulled. It seems that the direction was not stable. For this reason, even if a conventional patch is applied, it is considered difficult to correct wrinkles and slacks that occur on the skin so that the natural facial appearance can be efficiently obtained.

On the other hand, as shown in FIG. 2 (b), when properly affixed, the base material 2aL is affixed to at least a part of the skin portion 61 of the upper cheek, and the first extension part The 3aL first tip 5a and the second tip 22a of the second extension 6aL are attached to at least a part of the skin portion 62 in front of the ear. It can be said that the skin part 61 in the upper cheek is a skin part 63 between the constriction line 59 and the front of the ear. In a human whose deep constriction line 59 appears on the face, the skin portion 61 in the upper cheek is slackened and corresponds to the slackened skin portion 41. The skin portion 62 in front of the ear is firmly connected to the temporal bone by a tubular cartilage tissue or the like covering the external auditory canal 58 and the inner ear canal, and corresponds to the fixed skin portion 42.

While pulling the base portion 2aL and the first extending portion 3aL in the direction from the one end portion 4a toward the first tip portion 5a, the base portion 2aL is applied to at least a part of the skin portion 61 of the upper cheek, and then the first tip portion 5a is affixed to at least a part of the lower part of the skin portion 62 in front of the ear, and then the front end of the ear is pulled while pulling the second tip 22a in a direction different from the direction in which the second extension 22a is pulled. When applied to at least a part of the upper part of the skin part 62, the excess skin in the skin part 61 in the upper cheek is pulled toward the skin part 62 in front of the ear. As long as the patch 1aL is affixed, this pulled state can be kept stable even if the muscle contracts and the facial expression changes in daily life. For this reason, if the patch 1aL is appropriately affixed, the excess skin in the skin portion 61 on the loose upper cheek can be more efficiently corrected than when the conventional patch is affixed. Further, when the excess skin in the upper cheek skin portion 61 is corrected, the constricted line 59 is flattened and becomes shallower. For this reason, the patch 1aL can be suitably used as a skin correction patch for a person who has generated the deep constricted wire 59.

The facial muscle tissue directly or indirectly connects the bone tissue in the median part of the face and the bone tissue on the left or right side of the face (outside from the median). Furthermore, the facial muscles are connected so as to penetrate directly into the dermis of the skin. For this reason, as shown in FIG. 4C, the skin covering the tendon tissue at both ends of the facial muscle tissue (the median part of the face and the outside of the face) corresponds to the fixed skin part 42. Further, when the slack skin portion 41 hangs down due to gravity, wrinkles are generated in the skin, resulting in a senile facial appearance. For this reason, when the patch is applied to the slack skin portion 41 so as to be pulled toward the fixed skin portion 42 located on the upper outer side of the face with respect to the slack skin portion 41, In addition, the wrinkles in the inner and lower direction can be efficiently flattened to correct the senile facial features.

As shown in FIG. 2 (a), the first extending portion 3aL and the second extending portion 6aL of the patch 1aL are preferably centered on the face with respect to the constriction line 59 and the skin portion 61 on the upper cheek. Is applied to the skin portion 62 in front of the ear in the direction of the outer upper side. When the patch 1aL is applied in this way, the pulling force in the direction from the constricted line 59 to the skin part 62 in front of the ear via the skin part 61 in the upper cheek is spread over a wide range of excess skin in the skin part 61 in the upper cheek. The extended state is maintained. With this action, when the patch 1aL is properly applied, the constriction line 59 located on the lower inner side of the upper cheek skin portion 61 on the face can be efficiently flattened.

In addition, when applying the patch 1aL, the first extension 3aL is applied while pulling the first extension 3aL in the direction along the lower edge of the base 2aL and the first extension 3aL as much as possible, and then the second extension 6aL. It is good to stick it, pulling toward the fixed skin part 42 which exists on the outer side upper side of the face. When the first extending portion 3aL is pasted, the slack skin portion 41 is pulled in the direction along the lower edge of the base portion 2aL and the first extending portion 3aL, and further the second extending portion 6aL is moved. When affixed, the loosened skin portion 41 is further pulled toward the upper outside of the face. First, since the slack skin portion 41 is pulled in the direction along the lower edges of the base portion 2aL and the first extension portion 5aL, when pulling it toward the upper outside later, it is pulled. It becomes easy to stick while adjusting the direction and strength of traction force. It becomes easy to apply the patch 1aL so that the loose skin portion 41 can be corrected in a natural manner.

Since the base 2aL of the patch 1aL has a curved side in the substantially rectangular outer shape and the corners 18a are rounded, the traction force is locally concentrated on the contour of the base 2aL. In addition, the occurrence of an unnatural depression in the loose skin portion 41 is avoided. Further, since the base 2aL has a substantially square shape having a certain area, it can be applied to a wide range of the slack skin portion 41, and the slack skin portion 41 can be pulled over a wide range. For this reason, when the patch 1aL is pasted compared to the case where a pasting material having a thin base is pasted or the case where a patch having a small base area is pasted, the looseness of the skin looks efficiently and unnatural. It can be corrected so that there is no. Further, since the first extending portion 3aL and the second extending portion 6aL are tongue-shaped, they do not have an acute angle in their outer shapes, and traction force is locally applied to the skin portion to which these extending portions are attached. Concentrated and unnatural depressions can be avoided.

[Embodiment 2]
The patch (1fL, 1fR) according to Embodiment 2 shown in FIG. 5 (a) has the same configuration and operational effects as the patch 1aL described above, and the appropriate sticking method is also the same. However, since a part of the shape, a body part suitable for attachment, and the like are different, this different point will be described. Moreover, although the patch 1fL will be described, the description is the same for the patch 1fR having a mirror image symmetrical shape with respect to the shape of the patch 1fL. The patch 1fL includes a support 8f and an adhesive layer 9f, and further includes a base 2f, a first extension 3f, a second extension 6f, and a third extension 7f. In addition, in this invention, a 3rd extension part is an extension part affixed next after a 1st extension part and a 2nd extension part are affixed among several extension parts. .

The sticking material 1fL is E-shaped as a whole, and its base 2f has one end 4f and the other end 12f, and is substantially rectangular. The dimension of the base portion 2f is such that the shortest distance from one side 19f to the closest of the two concave vertices 20f is the horizontal length, and the shortest width of the base portion 2f in the direction perpendicular to the horizontal direction is the vertical length. When it is set as the length in the direction, it is, for example, 35 mm long × 35 mm wide.

The third extension portion 7f has a tongue-like outer shape, extends from the other end portion 12f, and extends in the direction in which the first extension portion 3f extends and in the direction in which the second extension portion 6f extends. It extends in a different direction. The tongue-like tip portion of the third extending portion 7f is referred to as a third tip portion 38f. Of the three extension parts, the extension part that is applied to the lowermost side when applying the patch 1fL to the body is the first extension part 3f, and the extension part that is attached in the middle is the second extension part. The extension portion 6f and the extension portion attached to the uppermost side as the third extension portion 7f are preferable from the viewpoint of correcting the slackness of the skin by pulling it from the lower side to the upper side. In this case, the extending direction of the first extending portion 3f and the extending direction of the second extending portion 6f are 5 to 10 degrees apart, and the extending direction of the second extending portion 6f and the third extending portion 7f The extending direction of the first extending portion 3f and the extending direction of the third extending portion 7f are opened 30 to 50 °.

Referring to FIG. 5 (b), the procedure of an appropriate application method for the adhesive material 1fL will be described. While pulling the base 2f and the first extension 3f in the direction from the one end 4f toward the first tip 5f of the first extension 3f, the base 2f is affixed to at least a part of the slack skin portion 41. The first tip portion 5f of the first extending portion 3f is affixed to the skin portion above the outside of the skin portion 41 that is slackened on the face while keeping this pulled state. Next, the second distal end portion 22f of the second extension portion 6f is above the outer side of the skin portion 41 that is slackened on the face while pulling in a direction different from the direction in which the first extension portion 3f is pasted while pulling. Apply to the skin. Finally, the third tip portion 38f of the third extension portion 7f is attached in a direction different from the direction in which the third extension portion 3f is attached while pulling the first extension portion 3f or the direction in which the second extension portion 6f is attached. While pulling, it is applied to the skin portion located on the outer side of the skin portion 41 slackened on the face.

As described above, the patch 1fL when properly applied in a state of being pulled in a plurality of directions has at least a base portion 2f of at least a part of the skin portion 64 of the upper cheek and at least a skin portion 68 of the lower eyelid. The shape is affixed to a part. Further, the first tip 5f is affixed to at least a part of the lower part of the skin part 62 in front of the ear, and the second tip 22f is affixed to at least a part of the upper part of the skin part 62 in front of the ear. The third tip portion 38f of the portion 7f is shaped to be affixed to at least a part of the temple portion 69 of the temple.

It can be said that the skin part 68 of the lower eyelid is a skin part 70 between the lower eyelid and the temple. A person who has a so-called crow's footprint 71 appearing at the corner of the eye (external eye corner) has slack in the skin portion 68 of the lower eyelid in addition to the bulge of the lower eyelid (so-called eye bag). Corresponds to the loose skin portion 41. The temple portion 69 of the temple is a part of the hairline portion 52 of the frontal hair and is firmly bonded to the skull periosteum via a cap-like aponeurosis, frontal fascia, temporal fascia, etc. This corresponds to the fixed skin portion 42. For this reason, if the patch 1fL is properly applied, the looseness of the skin portion 68 of the lower eyelid is corrected, and the footprint 71 of the crow becomes flat and shallow.

In addition, when the patch 1fL is properly applied, the effects exhibited when the above-described patch 1aL is appropriately applied are also exhibited. For this reason, the patch 1fL can be suitably used as a patch for correcting skin to a person who generates the deep constricted line 59 and at the same time the crow's feet 71 appear.

¡Those who have slack in the skin may receive cosmetic surgery or cosmetic surgery to correct the slack. After cosmetic surgery or cosmetic surgery, a patch is applied to the slack skin portion 41 so that the slack skin portion 41 is held in a desired shape. However, since the conventional patch is not in a shape suitable for holding the loose skin portion 41, the patch self-made by the patient is pasted on itself. When the shape and method of the patch were not appropriate, it took 6 months for the loose skin portion 41 to become the desired shape. The patient also needs to go to the clinic for follow-up by the doctor until the loose skin portion 41 has the desired shape. Over the course of June, I have been forced to visit many times.

Also, in patients suffering from facial nerve palsy, when the facial nerve on one side is damaged, the skin droops only on one side of the face, so the QOL is significantly reduced. There are various treatments for facial paralysis, but there are few treatments that have immediate effects. The patient continues to be followed up by the doctor until the symptoms improve, but in order to prevent a decrease in the patient's QOL during that time, a countermeasure that can hold the loose skin portion 41 in an appropriate shape has been demanded. . A patient who has undergone surgery or treatment due to facial paralysis may apply a patch so that the loose skin portion 41 is held in a desired shape. In this case as well, the patient's self-made patch was applied to himself, but it was difficult to efficiently hold the loose skin portion 41 so as not to have an unnatural appearance.

On the other hand, the patch material is used for patients who have undergone cosmetic surgery or cosmetic surgery for the skin portion 64 of the upper cheek and the skin portion 68 of the lower eyelid, or for patients who have undergone surgery or treatment due to facial paralysis. 1fL is excellent as a skin correction patch because it can simultaneously correct the skin portion 64 of the upper cheek and the skin portion 68 of the lower eyelid. For example, when the patch 1fL was used, the period until the skin portion 64 at the upper cheek became a desired shape was shortened to 2 months, that is, 1/3.

In addition, as shown to Fig.5 (a), it is preferable that the patch 1fL is provided with the release paper 14f provided with the cut 17f or the cut 24f. In this case, the release paper 14f is divided into a base covering portion 25f, a first tip portion covered portion 26f, a second tip portion covering portion 27f, and a third tip portion covering portion 39f.

[Embodiment 3]
The patch 1i according to Embodiment 3 shown in FIG. 6 (a) has the same configuration and operational effects as the patch 1aL described above, and the appropriate sticking method is also the same. However, since a part of the shape, a body part suitable for attachment, and the like are different, this different point will be described. The patch 1i includes a support 8i and an adhesive layer 9i, and further includes a base 2i, a first extension 3i, a second extension 6i, and a third extension 7i. The patch 1i has a line-symmetric shape that is Ψ-shaped as a whole, and its base 2i has a first end 4i and a second end 12i and is substantially rectangular. The dimension of the base 2i is defined as a horizontal length that is the shortest distance from one side 19i to the two concave vertices 20i, and the shortest width of the base 2i in the direction perpendicular to the horizontal direction is the vertical length. The length in the direction is, for example, 25 mm long × 35 mm wide. Of the three extending portions of the patch 1i, the extended portion on the axis of symmetry of the patch 1i is defined as a first extension 3i. Further, for the person to be affixed, one of the extension part affixed to the right side of the first extension part 3i and the extension part affixed to the left side is designated as the second extension part 6i, and the other is designated as the second extension part 6i. 3 extension part 7i. It is arbitrary which extension part of the right side or the left side is used as the second extension part 6i.

The first extension part 3i, the second extension part 6i, and the third extension part 7i extend from the other end part 12i in different directions. The extending direction of the first extending portion 3i and the extending direction of the second extending portion 6i are 45 to 60 ° open, and the extending direction of the first extending portion 3i and the third extending portion 7i is 45 to 60 °. The extending direction of the second extending portion 6i and the extending direction of the third extending portion 7i are 90 to 120 ° open.

As shown in FIG. 6 (b), the base material 2i when the base material 2i is properly attached while being pulled in a plurality of directions is attached to at least a part of the skin portion 74 between the eyebrows. The 1 extension part 3i, the 2nd extension part 6i, and the 3rd extension part 7i are the shapes stuck on at least one part of the skin part 75 of a forehead. Also, one end 4i of the base 2i is affixed to at least a part of the skin portion 76 on the back of the nose. A person who has wrinkles between the eyebrows has slackened skin portion 74 between the eyebrows, and the skin portion 74 between the eyebrows corresponds to the loosened skin portion 41. The nasal dorsal skin portion 76 corresponds to the fixed skin portion 42 because it is firmly fixed to the lower nasal bone and the upper outer nasal cartilage via the muscle tissue such as the nasal root muscle.

The sticking method of the patch 1i is the same as the sticking method described above for the patch 1fL according to the second embodiment. However, as compared with the method of applying the patch 1fL, the method of applying the patch 1i is to apply the second extension on the right or left side of the first extension 3i after the first extension 3i is attached. The difference is that the protruding portion 6i is pasted, and finally the third extending portion 7i that has not been pasted is pasted.

When the patch 1i is affixed, the skin portion 74 between the eyebrows is stably pulled in the direction from the skin portion 76 on the back of the nose to the skin portion 75 of the forehead through the skin portion 74 between the eyebrows. Is held. When the looseness of the skin portion 74 between the eyebrows is corrected, the wrinkles between the eyebrows are flattened and become shallow. For this reason, the patch 1i can be suitably used as a skin correction patch for a person who has wrinkles between the eyebrows. Also, the patch 1i is similar to the patch 1fL described above for patients who have undergone cosmetic surgery or cosmetic surgery for the skin portion 74 between the eyebrows, or for patients who have undergone surgery or treatment because of facial facial paralysis. Excellent as a skin correction patch.

In addition, as shown to Fig.6 (a), it is preferable that the sticking material 1i is provided with the release paper 14i provided with the cut 17i or the cut 24i. The release paper 14i in this case is divided into a base covering portion 25i, a first tip portion covered portion 26i, a second tip portion covering portion 27i, and a third tip portion covering portion 39i.

[Embodiment 4]
The adhesive material (1d, 1e, 1t) according to Embodiment 4 shown in FIGS. 7 (a), (b), and (c) has the same configuration and operational effects as the adhesive material 1aL described above, and an appropriate application method thereof. Is the same. However, since a part of the shape, a body part suitable for attachment, and the like are different, this different point will be described. The patch (1d, 1e, 1t) includes a support (8d, 8e, 8t) and an adhesive layer (9d, 9e, 9t), and further includes a base (2d, 2e, 2t) and a first extension portion. (3d, 3e, 3t) and the second extending portion (6d, 6e, 6t). Moreover, since the patch (1d, 1e, 1t) is a line-symmetric shape, it can be appropriately affixed to either the right or left side of the face.

The adhesive material 1d shown in FIG. 7 (a) is V-shaped as a whole, and its base 2d has a substantially rectangular shape having one end 4d and the other end 12d. The dimension of the base 2d is set such that the shortest distance from one side 19d to the concave vertex 20d is the horizontal length, and the shortest width of the base 2d in the direction perpendicular to the horizontal direction is the vertical length. For example, it is 15 mm long × 35 mm wide. The extending direction of the first extending part 3d and the extending direction of the second extending part 6d are opened by 40 to 60 °.

As shown in FIG. 7 (d), the base 2d of the patch 1d when properly pasted while being pulled in a plurality of directions is stuck to at least a part of the skin portion 68 of the lower eyelid. Also, the first tip 5d of the first extension 3d is affixed to at least a part of the lower part of the temple portion 69 of the temple. Further, the second distal end portion 22d of the second extending portion 6d is affixed to at least a part of the upper part of the skin portion 69 of the temple. As described above, the skin part 68 of the lower eyelid is the skin part 70 between the lower eyelid and the temple and corresponds to the loose skin part 41. The temple portion 69 of the temple corresponds to the fixed skin portion 42. When the slack of the skin part 68 of the lower eyelid is corrected, the footprint 71 of the crow becomes flat and shallow. For this reason, the patch 1d can be suitably used as a patch for skin correction for those who have crow footprints 71 appearing on the corners of the eyes.

The adhesive material 1e shown in FIG. 7 (b) has a U-shape as a whole, and its base 2e has one end 4e and the other end 12e and has a substantially rectangular shape that is short in the lateral direction. The dimension of the base portion 2e is the shortest distance from one side 19e to the concave vertex 20e as the horizontal length, and the shortest width of the base portion 2e in the direction perpendicular to the horizontal direction is the vertical length. For example, it is 40 mm long × 30 mm wide. The extending direction of the first extending part 3e and the extending direction of the second extending part 6e are opened by 30 to 50 °. Further, as shown in FIG. 7 (d), the adhesive material 1e when appropriately applied while being pulled in a plurality of directions is a body part similar to the adhesive material 1aL described above with reference to FIG. 2 (b). Affixed to For this reason, the adhesive material 1e can be suitably used as an adhesive material for skin correction to a person who has generated the deep constricted wire 59. Further, when two sheets of patch 1e are used, the same effects as when one patch 1aL and one patch 1aR are used are exhibited.

The adhesive material 1t shown in FIG. 7 (c) is U-shaped as a whole, and the base 2t has a side portion 4t and the other end portion 12t, and has a horizontally long substantially square shape. The dimension of the base 2t is defined as the shortest distance from one side 19t to the concave vertex 20t being the horizontal length, and the shortest width of the base 2t in the direction perpendicular to the horizontal direction being the vertical length. For example, it is 40 mm long × 53 mm wide. The extending direction of the first extending part 3t and the extending direction of the second extending part 6t are 30 to 50 ° open.

As shown in FIG. 7 (d), the base material 2t of the sticking material 1t when properly stuck to the sticking while being pulled in a plurality of directions is stuck on at least a part of the skin part 64 in the lower cheek. ing. Further, the first tip 5t of the first extension 3t and the second tip 22t of the second extension 6t are affixed to at least a part of the skin portion 65 at the front of the earlobe. Further, the skin portion 64 at the one end 4t and the lower cheek is pulled in a plurality of directions, a direction toward the first tip 5t and a direction toward the second tip 22t in a different direction.

It can be said that the skin part 64 in the lower cheek is a skin part 67 between the marionette line 66 and the front of the earlobe. In a human whose marionette line 66 appears on the face, the skin portion 64 below the cheek is loosened, and the skin portion 64 below the cheek corresponds to the loose skin portion 41. The skin portion 65 in the front of the earlobe is firmly connected to the temporal bone by cartilage tissue or the like covering the external auditory canal 58 and the inner ear canal, and corresponds to the fixed skin portion 42. When the slack of the skin portion 64 at the lower cheek is corrected, the marionette line 66 becomes flat and shallow. For this reason, the patch 1t can be suitably used as a patch for skin correction for those who have created the marionette line 66.

Since the base 2t of the patch 1t is longer than the base 2e of the patch 1e, it can be applied over a wide range of the loose skin portion 41. For this reason, when applied, the adhesive material 1t has a greater effect of correcting loosened skin than the adhesive material 1e. Further, the loose skin portion 41 is in a state in which the area of the skin is enlarged in all directions, but the extent of the enlargement varies greatly depending on the person or age. For these reasons, the patch 1e is preferably used as a patch for correcting senile facial features for a person whose skin area is slightly enlarged, for example, a person in their 40s or 50s. In addition, the patch 1t is preferably used as a patch for correcting senile facial features for a person whose skin area is greatly enlarged, for example, a person in their 60s or more.

The body part suitable for the application of the adhesive material (1e, 1t) and the number of adhesive materials applied at a time are not limited to the example shown in FIG. For example, the sticking material 1e when stuck while being pulled in a plurality of directions has its base 2e attached to at least a part of the skin portion 64 at the lower cheek, and the first tip 5e of the first extension 3e, And the 2nd tip part 22e of the 2nd extension part 6e is affixed on at least one part of the skin part 65 of the front part of the earlobe, and is used as a patch for skin correction with respect to the person who produced the marionette line 66. Also good. Further, another patch 1e is stuck while being pulled in a plurality of directions at the same body part as the patch 1aL described above with reference to FIG. You may exhibit the effect which corrects the looseness of the skin simultaneously with respect to both. Alternatively, the adhesive material 1t applied when pulled while being pulled in a plurality of directions is applied to a body part similar to the adhesive material 1aL described above with reference to FIG. On the other hand, it may be suitably used as a skin correction patch.

As shown in FIGS. 7A, 7B, and 7C, each of the patch materials (1d, 1e, 1t) is provided with a cut (17d, 17e, 17t) or a cut (24d, 24e, 24t). It is preferable to provide the release paper (14d, 14e, 14t). Each of the release papers (14d, 14e, 14t) in this case includes a base covering portion (25d, 25e, 25t), a first tip portion covered portion (26d, 26e, 26t), and a second tip portion covering portion (27d, 27e, 27t). Further, in the adhesive material (1d, 1e, 1t), the extension part that is attached to the lower side when attached to the body is the first extension part (3d, 3e, 3t), and the extension part that is attached to the upper side. The protruding portion is preferably the second extending portion (6d, 6e, 6t) from the viewpoint of correcting the loosened skin portion 41 to be lifted.

[Embodiment 5]
The adhesive material (not shown) according to Embodiment 5 has the same shape and effect as any of the adhesive materials (1aL, 1aR, 1d, 1e, 1fL, 1fR, 1i, and 1t) described above. The same applies to the application method and the body part suitable for application. Moreover, it is preferable to provide a release paper (not shown) provided with a cut (not shown). However, since the structure of a support body and an adhesive layer differs, this different point is demonstrated. The patch according to the present embodiment includes a support and a pressure-sensitive adhesive layer, and further includes at least a base portion having one end portion and another end portion, a first extension portion, and a second extension portion. Furthermore, you may comprise with a 3rd extension part.

The thickness of the support of the patch according to this embodiment is 6 to 50 μm, preferably 7 to 30 μm. When the thickness of the support is 6 to 50 μm, when the patch is applied to the skin, the user does not feel uncomfortable and the patch is easily held while being pulled. Further, when the thickness of the support is 7 to 30 μm, the thickness is easy for the user to handle the patch, and the patch exhibits a tensile stress suitable for correcting the skin. In addition, when the thickness of the support is too thin, the tensile stress of the support becomes weak while the sticking material is being pulled. If the tensile stress of the support becomes too weak, the traction force on the loose skin part becomes weak and the effect of correcting the skin becomes small. On the other hand, if the support is too thick, when the adhesive is applied to the skin, the person who has applied it feels uncomfortable on the skin.

The support of the patch according to this embodiment is composed of a film having a 20% tensile strength of 0.1 to 3 N / cm. When the 20% tensile strength of the support is 0.1 to 3 N / cm, the support exhibits an appropriate stretchability. Therefore, when the patch is applied to the skin, the patch follows the curved surface of the skin. While extending and contracting, it is easy to maintain the state of being pulled from the other end portion toward the extending portion. If the 20% tensile strength of the support is too small, the support is soft, so that the traction force on the loose skin part is weakened, and the effect of correcting the skin is reduced. Further, when the patch is peeled from the skin, the support expands and contracts more than necessary, so that it is difficult to peel off. If the 20% tensile strength of the support is too high, the support is highly resistant to stretching of the skin, so that the user feels uncomfortable on the skin and may cause skin irritation if applied for a long time. In addition, since the support does not expand and contract following the curved surface of the skin, the patch applied to the skin may be detached in a short time.

As a method for measuring 20% tensile strength, a test piece having a support cut to a width of 1 cm is prepared, the distance between chucks is set to 5 cm, and the test piece is pulled and deformed at a speed of 30 cm / min. The stress when the test piece is stretched by 20% is measured. The measured value at this time is defined as the 20% tensile strength of the support. Since the measured value may vary depending on the temperature depending on the material of the test piece, this measurement method is usually performed in a thermostatic chamber at 25 ° C.

The thickness of the adhesive layer of the patch according to this embodiment is 5 to 100 μm, preferably 10 to 40 μm. When the thickness of the pressure-sensitive adhesive layer is 5 to 100 μm, the patch is difficult to peel off from the skin, and when the patch is peeled off, the skin is prevented from being damaged and the skin is not easily moistened. If the thickness of the pressure-sensitive adhesive layer is too thin, the adhesive force is insufficient and it is difficult to adjust to the unevenness of the skin, so that the patch may unintentionally peel off from the skin. If the pressure-sensitive adhesive layer is too thick, the adhesive strength is too strong, and there is a risk of damaging the skin when peeling the patch from the skin. In addition, since the step between the patch and the skin is large, the patch is conspicuous, and the patch is easily caught on clothes and peeled off. Furthermore, when the pressure-sensitive adhesive layer is too thick, depending on the material of the pressure-sensitive adhesive, the moisture permeability of the pressure-sensitive adhesive layer is lowered, and the skin is steamed.

[Embodiment 6]
The patch (1q, 1r) according to Embodiment 6 shown in FIGS. 8 (a) and 8 (b) is the patch (1aL, 1aR, 1d, 1e, 1fL, 1fR, 1i, 1t) described above and Embodiment 5. It has the same shape and action effect as any one of the adhesive materials selected from the group consisting of the adhesive materials (not shown), and the same applies to the appropriate application method and body part suitable for application. Furthermore, it is also preferable that a release paper (14q, 14r) provided with a cut (17q, 17r) or a cut (24q, 24r) is provided. However, since the configurations of the support and the like are different, this different point will be described. The patch (1q, 1r) includes a support (8q, 8r) and an adhesive layer (9q, 9r), and further has a base (1q, 4r) and another end (12q, 12r). 2q, 2r), a first extension part (3q, 3r), and a second extension part (not shown). Furthermore, you may comprise with a 3rd extension part (not shown).

When the thickness of the support (8q, 8r) is w, the patch (1q, 1r) has a ten-point average roughness Rz of the other surface (10q, 10r) of the support (8q, 8r), 6 μm ≦ Rz ≦ 40 μm and Rz ≦ w. Further, the adhesive material (1q, 1r) has an Rz on the other surface (10q, 10r), preferably 10 μm ≦ Rz ≦ 40 μm and Rz ≦ w, where w is the thickness of the support (8q, 8r). More preferably, 17 μm ≦ Rz ≦ 35 μm and Rz ≦ w. The Rz of the other surface (10q, 10r) is measured in accordance with JIS B 0601: 2001 under the conditions of a reference length of 500 μm and a cut-off value of 200 μm using a surface roughness measuring instrument. This is the value obtained.

The support (8q, 8r) is provided with irregularities on the other surface (10q, 10r) so that the surface property is 6 μm ≦ Rz ≦ 40 μm. Since the depth of the irregularities satisfying 6 μm ≦ Rz ≦ 40 μm is close to the depth of the irregularities on the skin surface, the appearance of the other surface (10q, 10r) is similar to that of the skin. In addition, since the incident light from the other surface (10q, 10r) into the support (8q, 8r) is scattered due to the uneven shape, the other surface (10q, 10r) is not conspicuous because its shine is suppressed.

The depth of the irregularities satisfying 6 μm ≦ Rz ≦ 40 μm is such that when the foundation powder is applied after the concealer powder is applied to the other surface (10q, 10r), these multiple types of cosmetic powders Suitable for holding on the surface (10q, 10r). The average particle diameter of the foundation or concealer is generally as wide as 0.1 to 60 μm, whereas the unevenness is the particle diameter when the other surface (10q, 10r) has an uneven depth of 6 μm ≦ Rz ≦ 40 μm. Since it is possible to hold a plurality of types of cosmetic powders, the makeup paste is good.

If the Rz of the other surface (10q, 10r) is less than 6 μm, the depth of the unevenness is too small with respect to the average particle diameter of the foundation powder or the concealer powder. In many cases, it is hardly held at 10r). Even if these cosmetic powders are applied with a fingertip by stroking, the cosmetic powder slides off from the other surface (10q, 10r). If the Rz of the other surface (10q, 10r) exceeds 40 μm, the depth of the unevenness is too large with respect to the average particle diameter of these cosmetic powders, so the cosmetic is applied too thickly on the other surface (10q, 10r). It is difficult to wipe it off. In addition, since the other surface (10q, 10r) has an unevenness depth of 17 μm ≦ Rz ≦ 35 μm, the depth of the unevenness is similar to that of the skin. Cosmetics can be wiped off from the other side (10q, 10r).

Rz ≦ w indicates that the depth of the unevenness formed on the other surface (10q, 10r) is equal to or less than the thickness w of the support (8q, 8r). When Rz = w, a large number of through holes from the other surface (10q, 10r) to one surface (11q, 11r) are provided in the support (8q, 8r), and the adhesive layer ( 9q, 9r) are exposed. Also in this case, the foundation powder and the concealer powder are held by the unevenness formed on the other surface (10q, 10r). In addition, if the cosmetic to be applied is a paste-like cosmetic or a liquid cosmetic containing particles, it is easy to be held on the other surface (10q, 10r), and the applied cosmetic is applied. The appearance of the material (1q, 1r) is preferable because it is easy to adjust to the surrounding skin.

In the patch 1q shown in FIG. 8 (a), the support 8q is made of a polyacrylate resin. The patch 1q includes a carrier 15q provided with a hard film 28 and an adhesive layer 29 that covers one surface of the film 28. The pressure-sensitive adhesive in the pressure-sensitive adhesive layer 29 of the carrier 15q does not flow out because of its high cohesive force. The adhesive layer 29 of the carrier 15q covers the other surface 10q. Since the adhesive layer 29 of the carrier 15q is as thin as 3 to 20 μm, the user can easily peel the carrier 15q from the other surface 10q. The irregularities formed on the other surface 10q are protected by the carrier 15q until immediately before the patch 1q is pasted. When manufacturing the patch 1q, since the support 8q is supported by the carrier 15q, it is easy to manufacture the patch 1q.

As for the patch 1r shown in FIG.8 (b), the support body 8r is comprised with the polyurethane. The patch 1r includes a carrier 15r including a film 28. Since the polyurethane constituting the support 8r has weak adhesive strength, the carrier 15r may not be provided with an adhesive layer. Other configurations and operational effects of the patch 1r are the same as those of the patch 1q described above.

Conventionally, there has been a problem that when the adhesive material is applied to the face or the like to correct the loose skin part, the adhesive material becomes conspicuous. The skin portion that can be stuck so that the patch is not conspicuous is limited to the portion hidden behind the head hair such as the back side of the ear or the portion hidden by the clothes (see Patent Document 1). Patients who have undergone cosmetic surgery or cosmetic surgery, or surgery or treatment for facial nerve palsy, apply a large-sized patch to the face to keep the loose skin part in the desired shape. QOL was lowered by the material. In particular, female patients who went out during the day had significantly reduced QOL.

On the other hand, even if the patch (1q, 1r) is affixed to the skin such as the face, the other surface (10q, 10r) resembles the skin and is hardly noticeable. Furthermore, when the patch (1q, 1r) is applied to the other surface (10q, 10r) after being applied to the skin, it is almost indistinguishable from the skin. For this reason, even if the patch (1q, 1r) is affixed to the facial skin, the QOL of the user is hardly reduced. You can contribute to keeping the quality of life for those who go out during the day, especially women and patients.

In addition, the base holding means with which this sticking tool is equipped may be one, and may be three or more.

[Other Embodiments]
The patch according to the present invention has the same configuration and operational effects as those of the patches (1aL, 1aR, 1d, 1e, 1fL, 1fR, 1i, 1t, 1sL, not shown) according to the first to seventh embodiments. In addition, you may have the structure and effect which are further demonstrated below.

The moisture permeability of the patch is preferably 500 to 10,000 g / (m ² · day). Since water vapor of about 300 g / (m ² · day) is generated from the skin on a daily basis, if it is less than 400 g / (m ² · day), the skin is steamed and normal bacteria on the skin proliferate, causing inflammation in the skin. May happen. If it exceeds 10,000 g / (m ² · day), when water, sweat, or alcohol is absorbed by the patch, the patch swells and tends to exfoliate and become conspicuous. Further, if it exceeds 10,000 g / (m ² · day), the wound is dried when the patch 1aL is applied to the wound surface, so that the wet therapy cannot be performed with the patch.

The moisture permeability of the patch is preferably 800 to 4,000 g / (m ² · day), more preferably 1,000 to 3,500 g / (m ² · day). When it is 800 to 4,000 g / (m ² · day), the skin is less likely to be stuffy and the patch is less likely to swell, and when the patch 1aL is applied to the wound, a moist environment is formed to quickly cure the wound. it can.

In the adhesive materials according to Embodiments 1 and 4 to 7, the extending direction of the first extending portion and the extending direction of the second extending portion may be opened by 10 to 90 °, or opened by 20 to 60 °. Preferably it is. In the patch materials according to Embodiments 2 and 3, the extension directions of the two most distant extension portions out of the three extension portions may be 10 to 180 ° apart from each other, and 30 to 120 ° each other. It is preferably open. In addition, the patch according to the present invention is configured to include four or more extending portions extending in different directions from the other end portion, and the most distant 2 of the four or more extending portions. The extending directions of the two extending portions may be open within a range of 20 to 180 °. If these angles are too small, the range between the extended portions to which the slack skin portion is pulled becomes narrow, and the effect of correcting skin slack becomes weak. Alternatively, if these angles are too large, the traction force extending in a certain direction between the extension portions is weak, so that the effect of correcting skin slack becomes weak.

In the adhesive material according to Embodiments 1 and 4 to 7, the extension portion that is the first extension portion is the second extension portion, and the extension portion that is the first extension portion is the second extension It may be handled as a part. In the patch according to the second embodiment, the extension portion that is the first extension portion is the third extension portion, and the extension portion that is the third extension portion is handled as the first extension portion. Also good.

In this patch, the first extension part 3i, the second extension part 6i, and the third extension part 7i of the patch 1i according to Embodiment 3 are shown in FIGS. 6 (a) and 6 (b). The shape may extend longer than that. When the patch material in this case is appropriately affixed to a body part similar to the patch material 1i shown in FIG. 6B, the base portion is a skin portion 74 between at least a part of the nasal dorsal skin portion 76 and the eyebrows. Each of the three extending portions vertically cuts the forehead skin portion 75 in a different direction from the skin portion 74 between the eyebrows, a first tip portion, a second tip portion, And each of 3rd front-end | tip parts is affixed on at least one part of the skin part 52 in the hairline of the frontal head. In this case, the skin portion 74 between the base and the eyebrows extends from the skin portion 76 of the back of the nose to the skin portion 74 between the eyebrows, and branches in three directions to vertically cut the forehead skin portion 75 in each direction. It is held in a state of being pulled so as to be directed to different portions of the skin portion 52 at the hairline of the hair. Also, in this case, one end of the patch is affixed to at least part of the nasal dorsal skin portion 76 (fixed skin portion 42), and the first tip portion, the second tip portion, and the third tip portion are in front. Since it is affixed to at least a part of the hairline 52 (fixed skin part 42) of the hairline of the head, the skin part 74 between the eyebrows between the two fixed skin parts 42 is upward from below The state of being pulled to is maintained more stably.

As a loose skin part other than the face in humans, there are a skin part at the lower part of the lower jaw margin of the neck, a skin part of the wrist, a skin part of the chest (breast), and a skin part of the buttocks. The fixed skin parts close to these loose skin parts are, in turn, the hair part of the neck part of the back of the neck (nape), the skin part of the wrist joint at the distal forearm, and the upper sternal edge. And the skin part of the clavicular part and the skin part of the iliac margin.

For example, in the state where the base is affixed to at least a part of the skin part of the lower part of the lower jaw margin of the neck and is pulled in one direction from one end toward a plurality of extensions, If it is attached to at least a part of the upper part of the neck rear side, the excess skin of the lower jaw edge can be raised. For this reason, the face line can be improved by making the lower jaw edge look sharp and correcting so that the excess skin on the front surface of the neck is reduced. As described above, in addition to the patch according to the first to seventh embodiments, if the shape of the patch is prepared according to the positional relationship between the loose skin part and the fixed skin part other than the human face, Wrinkles and loosening of the skin can be corrected with a patch even at sites other than the human face.

[Manufacturing method of patch]
The method for producing a patch according to the present invention includes a step of obtaining a support, a step of obtaining a pressure-sensitive adhesive layer, a step of laminating the support and the pressure-sensitive adhesive layer, and a step of cutting out the laminate. Here, a method for manufacturing the patch according to the first to fifth and seventh embodiments will be described. In the step of obtaining a support, the support C was a film obtained by casting a resin solution on the surface of a casting peelable substrate and drying it, and peeling the dried product from the substrate.

In the step of obtaining the pressure-sensitive adhesive layer, when an acrylic resin is used as the material for the pressure-sensitive adhesive layer, the monomers that are the raw materials for the pressure-sensitive adhesive are mixed and dissolved in ethyl acetate, and a polymerization initiator is added and copolymerized. The solution for casting is prepared by adding a crosslinking agent. Moreover, when using a silicone adhesive for the raw material of an adhesive layer, the solution for casting is prepared using the commercially available silicone adhesive which is the system etc. which mix a predetermined two types of solution. When rubber adhesive is used as the material for the adhesive layer, the polymer that is the raw material of the adhesive is mixed and dissolved in toluene, and a softening agent, tackifier, and antioxidant are added to prepare a casting solution. To do. When a urethane-based pressure-sensitive adhesive is used as the material for the pressure-sensitive adhesive layer, a predetermined two types of solutions are mixed immediately before casting to prepare a casting solution. Furthermore, in the case of using any acrylic, silicone, rubber, or urethane-based adhesive, the casting solution described above is cast on a release paper, and the cast is dried or heated to be adhesive. The agent layer D was obtained.

In the laminating step, one surface of the support C is placed on and bonded to the surface of the pressure-sensitive adhesive layer D that is not covered with the release paper, and a laminate of the support C, the pressure-sensitive adhesive layer D, and the release paper. Got. In the cutting process, the laminate is cut into a predetermined shape from the other surface side of the support C. The patch according to any of Embodiments 1 to 5 and 7 can be obtained depending on the shape at the time of cutting.

A method for manufacturing a patch according to Embodiment 6 will be described. In the step of obtaining the support, the resin solution is cast on the surface of the peelable substrate for casting having an inverted pattern on the surface and dried, and the dried film is peeled from the substrate to obtain the support E did. On the other surface (transfer surface) of the support E, the reverse pattern on the surface of the peelable substrate for casting is transferred to form irregularities. A carrier is laminated on the other surface (transfer surface) of the support E to obtain a laminate of the support E and the carrier. In addition, a laminate of the pressure-sensitive adhesive layer D and the release paper is obtained in the same manner as the method for manufacturing the patch according to Embodiments 1 to 5 and 7 described above. One surface of the support E (the surface that is not the transfer surface) is placed on and bonded to the surface of the pressure-sensitive adhesive layer D that is not covered with the release paper, and the release paper, the pressure-sensitive adhesive layer D, the support E, The laminated body laminated | stacked in order of the carrier was obtained. When this laminate is cut out in a predetermined shape from the carrier side, the patch according to Embodiment 6 can be obtained.

In the case of providing a pressure-sensitive adhesive layer made of a hydrocolloid pressure-sensitive adhesive as a raw material, the method for producing this patch comprises mixing 15 to 55% by weight of hydrocolloid particles, 20 to 50% by weight of a softening agent, and a tackifier. Further, mixing while heating to 130 to 150 ° C. Thereafter, a water-absorbing component is further added and mixed uniformly, and then applied onto release paper to form an adhesive layer on the release paper. Then, in the same manner as in the method for manufacturing a patch according to any one of Embodiments 1 to 5, a patch having a pressure-sensitive adhesive layer made of a hydrocolloid pressure-sensitive adhesive can be obtained. Here, as a block polymer, 1 or more types chosen from the group which consists of a styrene isoprene styrene block copolymer, a styrene butadiene styrene block copolymer, etc. are mentioned, for example. Instead of this block polymer, polyisobutylene or polybutene may be used. Examples of the softening agent include one or more selected from the group consisting of mineral oil (liquid paraffin) and polybutene.

[Method of Comparative Test Using Examples 7 to 11 and Comparative Examples 4 and 5]
Seven females aged 38 to 67 years affixed the adhesive materials according to Examples 7 to 11 each time on their faces with their own hands, like the adhesive material 1e shown in FIG. 7 (d). When affixing, while pulling in the direction from one end to the first tip, the base was affixed to the loose skin part of the cheek, and the first tip was affixed to the lower part of the skin part in front of the ear. Furthermore, the second tip portion was attached to the upper part of the skin portion in front of the ear while pulling the second extension portion in a direction different from the direction in which the first extension portion was attached while being pulled. After the application, the cosmetic surgeon observed the faces of seven women and evaluated the skin correction effect of the adhesives according to Examples 7 to 11 according to the following criteria.
◎ All of the seven people raised their cheeks and became shallower.
○ More than 4 out of 7 people, cheeks were raised and the holy line became shallower.
△ More than 4 out of 7 people raised their cheeks slightly, but the tie line did not become shallow.
× There were 3 or fewer of the 7 people whose cheeks were slightly raised and the frying line became shallower.

Seven same women affixed one end of the patch according to Comparative Examples 4-6 to the upper cheek skin, and affixed one end while pulling in one direction from one end to the other It was affixed to the skin part in front of the ear above the outside of the skin part. In this case as well, the skin correction effect was evaluated in the same manner as when the patches according to Examples 7 to 11 were applied.

In addition, a questionnaire was conducted to determine whether the seven women who applied the patch materials according to Examples 7 to 11 and Comparative Examples 4 to 6 felt discomfort on the skin after application. Based on the results of the questionnaire, the following criteria were used to evaluate whether the patch was uncomfortable.
◎ All 7 people felt the same as when nothing was affixed.
○ More than 4 out of 7 felt the same as when nothing was affixed.
△ More than 4 out of 7 felt that something was stuck on the upper cheek.
× 4 or more of 7 people felt stress because they were affixed to the upper cheek.

Seven women who applied the patch materials according to Examples 7 to 11 and Comparative Examples 4 to 6 looked at their faces with a mirror and observed whether the patch material was noticeable. The observation results were taken in a questionnaire, and from the questionnaire results, the conspicuousness of the patch was evaluated according to the following criteria.
◎ If all 7 people did not look carefully, they could not know that the patch was applied.
○ More than 4 out of 7 people could not find the patch unless they looked carefully.
Δ: Four or more out of seven people did not know the patch just by looking at it for a moment.
X Four or more of the seven persons were found to have the patch applied just by looking at it for a moment.

A commercially available foundation was prepared, and the median diameter of the foundation powder was measured by a particle size analysis / laser analysis method in accordance with JIS Z 8825-1: 2001, and found to be 6 μm. In addition, seven women who applied the adhesive materials according to Examples 7 to 11 and Comparative Examples 4 to 6 to the upper cheeks included the above-mentioned foundation on the other surface of the adhesive support. Apply to make up. After the makeup, a questionnaire was given about the paste on the makeup, and the ease with which it was applied was evaluated according to the following criteria.
◎ All seven felt that the skin and makeup paste did not change.
○ More than 4 out of 7 felt that the skin and makeup paste did not change.
△ More than 4 out of 7 people felt uncomfortable with makeup paste compared to bare skin.
× More than 4 out of 7 people felt that the makeup paste was clearly worse than the bare skin.

Seven women who applied the adhesives according to Examples 7 to 11 and Comparative Examples 4 to 6 lived as usual for one day, and applied 24 hours after applying the adhesives. The long-term stickability of the patch was evaluated to determine whether the patch was still stuck. Seven women took a bath once every 24 hours. The long-term stickability of the patch was evaluated according to the following criteria.
◎ With all seven people, the patch remained stuck without peeling off.
○ More than 4 out of 7 people were stuck without any peeling material.
Δ: At least 4 out of 7 people were stuck with the patch material peeled off.
X The patch material was peeled off by 4 or more of 7 people.

[Results and discussion of comparative tests using Examples 7 to 11 and Comparative Examples 4 and 5]
Table 1 shows the results of the tests on the patch materials according to Examples 7 to 11 and Comparative Examples 4 and 5, such as the effects of correcting the skin, difficulty in feeling uncomfortableness, difficulty in conspicuousness, ease of applying makeup, and long-term adhesiveness. Shown in

As shown in Table 1, when the patches according to Examples 7 to 11 were applied, all seven persons could raise the skin part of the loose upper cheeks and shallow the fray line. It was. Since the patch materials according to Examples 7 to 11 include the first extension part and the second extension part, a sufficiently strong traction force is dispersed in an appropriate direction on the skin part of the loose upper cheek. It is thought that it was possible to correct wrinkles and looseness of the skin in a natural way.

On the other hand, when the patch materials according to Comparative Examples 4 to 6 were applied, only 1 to 2 out of 7 people had cheeks raised slightly and the fringe line became shallow, and the upper cheeks There were 3-5 people who had unnatural depressions. The patch materials according to Comparative Examples 4 to 6 are not provided with a plurality of extending portions, and can only pull the skin part of the loose upper cheek in a single direction. It is considered difficult for those who have not done so to properly correct the skin. Furthermore, since the thickness of the support according to Comparative Example 5 is too thin, 3 μm, the tensile strength of the support is weakened while being applied to the skin while towing, and the loose skin part is applied. It seems that the traction force exerted was weakened and the effect of correcting the skin was reduced.

In addition, when the adhesive materials according to Examples 7 to 11 and Comparative Examples 5 and 6 were applied, 4 to 7 of 7 people felt the same as when nothing was applied. The patch materials according to Examples 7 to 11 and Comparative Examples 5 and 6 have a thickness of the support of 3 to 20 μm, or Rz of the other surface of the support is 6 μm or more, so 20% The tensile strength is 0.1 to 3 N / cm. For this reason, the adhesive materials according to Examples 7 to 11 and Comparative Examples 5 and 6 exhibit the flexibility to expand and contract following the curved surface of the skin while pulling the skin part of the upper cheek, so that the user can It seems that it became difficult to memorize a sense of incongruity.

On the other hand, when the adhesive patch according to Comparative Example 4 was applied, 5 out of 7 persons felt stress because the adhesive patch was applied to the upper cheek. In the patch according to Comparative Example 4, since the support was as thick as 55 μm, it was considered that the tensile stress was too strong, causing the skin after the patch to feel uncomfortable.

When the patches according to Examples 9 to 11 and Comparative Example 6 were affixed, it was not known that all of the seven people had affixed the patch on the upper cheeks unless they looked carefully. The adhesive materials according to Examples 9 to 11 and Comparative Example 6 have Rz of 15 to 18 μm on the other surface, and the support contains fine particles. For this reason, it is considered that the unevenness formed on the other surface and the fine particles contained in the support scattered the incident light on the patch, and the shine on the other surface was suppressed, making it less noticeable. Further, the support is translucent, the appearance is similar to the skin surface due to the irregularities formed on the other surface, and the fine particles are close to the color of the skin.

When the patches according to Examples 7 and 8 were pasted, 4 to 6 of the 7 persons did not know that the patches were stuck on the upper cheeks unless they looked carefully. Since the adhesive materials according to Examples 7 and 8 have a small Rz of 6 μm on the other surface, the effect of scattering incident light on the support is weak, and some shine is generated. When the patch material according to Comparative Example 5 was pasted, it was found that the patch material was pasted by only 3 of 7 people seeing for a moment, and when the patch material according to Comparative Example 4 was pasted, 7 All the names were found to have the patch attached just by looking at it for a moment. Since the patch materials according to Comparative Examples 4 and 5 had Rz of 0.2 μm on the other surface and almost no irregularities were formed, the shine caused on the other surface was conspicuous. In particular, since the thickness of the support of the patch according to Comparative Example 4 was as thick as 55 μm, the level difference between the support and the skin was conspicuous.

When the patches according to Examples 10 and 11 and Comparative Example 6 were applied, 4 or more of 7 people felt that the skin and makeup paste did not change even when applying makeup on the other side of the patch. . For the powder of the foundation having a median diameter of 6 μm, the adhesive materials according to Examples 10 and 11 and Comparative Example 6 were formed on the other surface because Rz of the other surface of the support was 15 to 18 μm. It is considered that the powder is efficiently held on the unevenness and that the paste is good. Since the adhesive materials according to Examples 7 and 8 have Rz of 6 μm on the other surface, the size of Rz on the other surface is the same as the median diameter of the foundation powder. In addition, 5 out of 7 people felt uncomfortable when the makeup paste was a little worse than the bare skin. In the adhesive materials according to Examples 7 and 8, the powder having a diameter less than the median diameter was held on the other surface, but most of the powder having a diameter larger than Rz on the other surface slipped off from the other surface. It is thought.

When the patch materials according to Comparative Examples 4 and 5 were affixed, the foundation powder slipped off from the other side, and all seven felt that the makeup paste was clearly worse than the bare skin. Rz of the other surface of the adhesive material according to Comparative Examples 4 and 5 is 0.2 μm, and the depth of the unevenness formed on the other surface is too shallow with respect to the median diameter of the powder of the foundation. It is thought that it was not held on the surface.

When the adhesive materials according to Examples 7 and 11 and Comparative Example 5 were applied, the adhesive material remained attached without being peeled off by all 7 persons when 24 hours had elapsed since application. The adhesive materials according to Example 7 and Comparative Example 5 have a thin support of 3 to 10 μm and are easy to follow the curved surface and movement of the skin. it is conceivable that. In the patch according to Example 11, the thickness of the support is 25 μm and is slightly thick, but the Rz of the other surface is as large as 18 μm, and the moisture permeability of the support is as high as 2,400 g / (m ² · day). Furthermore, since hyaluronic acid is contained in the pressure-sensitive adhesive layer as a moisturizing agent and potassium glycyrrhizinate is added as an anti-inflammatory agent, it is considered that the skin surface is hard to be stuffy and has a long-term sticking property.

When the patch materials according to Examples 8 to 10 and Comparative Example 6 were pasted, 4 to 6 out of 7 persons remained stuck without peeling off. The adhesive materials according to Examples 8 to 10 and Comparative Example 6 have a support thickness of 20 to 25 μm, which is slightly thick, but the other surface has Rz of 6 to 18 μm. It is considered that the skin surface is kept dry and the long-term sticking property is good. On the other hand, the patch according to Comparative Example 4 was four out of seven, and the patch was peeled off. Since the support is as thick as 55 μm and the Rz on the other surface is as small as 0.2 μm, it is considered that the moisture permeability of the support is low and the skin surface is steamed and the long-term stickability is poor. Furthermore, since the support is as thick as 55 μm, the tensile strength of the support is strong, the support cannot follow the movement of the skin, and long-term stickability is considered to be poor.

In addition, although the adhesive which concerns on Example 10 contained collagen and vitamin C in the adhesive layer, the long-term sticking property was good. For this reason, when the patch according to Example 10 is used, it is expected that vitamin C and collagen can exhibit the effect of keeping the skin firm and the effect of whitening. Moreover, although the adhesive layer which concerns on Example 11 contains the anti-inflammatory drugs potassium glycyrrhizinate and hyaluronic acid in the adhesive layer, the long-term sticking property is good and exhibits the anti-inflammatory effect and the moisture retention effect of the skin. It is considered possible.

The sticking material according to the present invention can be applied to a loose skin part to efficiently correct wrinkled or loose skin. When this patch is affixed to the elderly person's face, the loose skin is raised, making the elderly person a young and natural face. Moreover, the sticking method of this patch is a method of sticking this patch appropriately on the skin, and the patch stuck by this method exhibits an excellent effect of correcting the skin. In addition, the patch of the present patch allows the patch to be appropriately and quickly applied to the skin even when the size of the patch is large.
