Description

Sheet for wrinkle improvement and manufacturing method thereof {SHEET COMPRISING LAMINATE STRUCTURE FOR NECK WRINKLES AND METHOD OF MAKING SAME}

The present invention relates to a sheet for improving wrinkles on the back of a neck or hand, and a sheet for improving wrinkles having a microneedle formed on one side thereof, and a method for manufacturing the same.

Generally, wrinkles on the face are caused by a variety of causes. Wrinkles occur due to deterioration of elasticity as collagen and dermis components in the upper layer deteriorate as the skin ages, or it may occur due to the skin being stretched by gravity, and the muscles of the face relax and contract according to facial expressions. Occurs because it is repeated.

In addition, internal causes include blood circulation, genetic factors, poor nutrition, stress, and diseases, and external factors include ultraviolet rays, smoking, climate, or cosmetic irritation.

Surgical surgery is a method for treating wrinkles. This method has been widely practiced for a long time, and is a surgical operation that removes a large part of skin and mechanically pulls the skin to make it taut.

This has the advantage of being able to see the effect quickly and without the need for postoperative care. However, surgical scars may remain, and since the skin itself is the aging skin, there is a disadvantage that the generation of wrinkles continues.

Another method is to insert a supplement into certain wrinkles. This treatment is aimed at relieving deep wrinkles, and implants include prosthetics made of autologous fat, collagen, and other special synthetics.

Another method is to inject a substance, such as botox or restylene, into the wrinkles. This results in a very satisfactory result compared to a short procedure time, and as time passes, it returns to its original form and reduces anxiety about the result of the surgery and has the advantage of avoiding side effects caused by the surgery.

Finally, there is a method of regenerating the skin using a laser. This treatment removes some layers of skin and induces skin regeneration to treat wrinkles. This has the advantage of delaying the progression of wrinkles, but because it is to regenerate after removing a part of the skin, it needs to be managed for a certain period of time.

However, the conventional methods for treating wrinkles according to the above techniques take a lot of time in one procedure as well as have to manage for a certain period of time, so it is difficult to go out after the procedure.

Moreover, the above techniques do not manage wrinkles during daily life as a concept of treatment, and thus, there is a problem that the procedure is expensive.

Looking at the background art to solve this problem, in the "Sheet containing a laminated structure and its manufacturing method" of the Republic of Korea Patent Publication No. 10-1770764 (hereinafter 'Document 1'), the user including the microneedle formed layer The present invention discloses a sheet capable of absorbing not only the physiologically active substance required for skin care to the skin but also using both surfaces and partially adhering to the skin.

When using the invention of the document 1, it is formed of a material containing elasticity has the advantage that it is easy to fix on the skin, but when applied to a lot of movements such as the user's chin, neck, hands, and the like affected by gravity, There is a disadvantage that a separate fixing structure must be included by the adhesive force.

Looking at another background, the "neck band" of the Republic of Korea Patent Publication No. 10-2013-0034158 (hereinafter referred to as 'Document 2'), the band is applied to the wrinkle-relieving agent and adhesive applied to alleviate neck wrinkles .

In the case of using the invention of Document 2, because the band and the anti-wrinkle agent are used, both the action of the drug and the action of pulling the skin are performed to alleviate the wrinkles, and at the same time, the two anti-wrinkle functions are performed to efficiently wrinkle the skin. There is an advantage to alleviate, but the drug is applied to the outside of the skin has a disadvantage in that it is difficult to effectively deliver deep into the skin.

Looking at the other background, in the "Making a sheet for masks (Mask Sheet) and its manufacturing method" of the Republic of Korea Patent Publication No. 10-2005-0071394 (hereinafter 'Document 3'), a material such as non-woven or cotton fabric The present invention discloses a mask sheet capable of improving wrinkles of the chin as well as the neck by applying a mask sheet for neck area using cosmetic raw materials and moisture, which are effective for beauty.

When using the invention of Document 3, it is applied to not only the neck but also the jaw, there is an advantage that the skin care of the jaw and the neck is easy to manage, but there is a lot of movement, and there is a disadvantage that the mask sheet flows from the neck and the jaw under the influence of gravity.

Looking at another background, in the "neck mask sheet" of the Republic of Korea Utility Model Publication No. 20-2010-0010700 (hereinafter 'Document 4'), a central incision is formed in the center of the sheet to suit various neck lengths for each person In addition, the present invention discloses a mask sheet suitable for the neck part by including an incision in the lower end of the sheet so as not to be folded or lifted due to the bending of the human body.

When using the invention of Document 4, the sheet is overlapped by the incision to further improve the management effect in the deep wrinkles in the center of the neck, and also to prevent the sheet from being folded or lifted by the structure of the neck. However, the cosmetics contained in the mask sheet can not be delivered deep into the skin has the disadvantage that the skin beauty effect is significantly reduced.

<Example 1>

As shown in FIGS. 1 and 2, the sheet for improving wrinkles according to the present invention (hereinafter referred to as a sheet) may include a first layer 100, a second layer 200, and a third layer 300. It may be formed to include.

In more detail, the first layer 100 may be formed of any one selected from fabric, PU, and liquid silicone.

Preferably the fabric is a non-woven fabric, polyester (polyester), cotton, spandex, nylon (nylon), liquid silicone, hydrogel formed of any one selected from PE (polyethylene), PP (polypropylene) or PU (polyurethane) (hydrogel) or biocellulose can be formed of any one.

More preferably, it may be made of a nonwoven fabric.

The nonwoven fabric is inexpensive in manufacturing cost, can freely change its thickness, not wrinkle, does not easily loosen the end, free of altar, and has a wide range of tensile strength and rupture strength. When bonded, wrinkles and shape stability has a great advantage.

Most preferably, any one selected from chemical bonding nonwoven fabric, thermal bonding nonwoven fabric, array nonwoven fabric, wet nonwoven fabric, needle punching nonwoven fabric, spandex, and spanbond may be applied, but is not limited thereto.

Optionally, the first layer 100 is formed of the same or similar color as the skin of the user, including apricot, white, black, etc., so that the heterogeneity does not occur when the user lives daily with the sheet attached. It may be formed, but is not limited to this, of course.

In addition, as illustrated in FIG. 2, the first layer 100 may be formed in two or more colors so that a portion in which any one selected from the support 301 or the microneedle 302 is formed may be distinguished.

At this time, the first layer 100 is formed in two or more colors by dyeing so as to distinguish any one selected from the support 301 or the microneedle 302 can be easily adhered to the user desired site It can be formed to be.

Next, the second layer 200 may be formed on one side of the first layer 100 and may be formed of a polymer.

In more detail, the second layer 200 may be formed of any one selected from silicon, PU (polyurethane), hybrid silicon, or rubber.

Preferably, it may be formed of silicon, but is not limited thereto.

The application of silicone is chemically stable, almost non-reactive, non-toxic to the body, excellent resistance to water, heat or oxidation, and the elasticity of silicone facilitates adhesion and fixation to skin of various lengths or widths. There is an advantage.

In this case, the thickness ratio of the first layer 100 and the second layer 200 may be formed in a ratio of 1: 0.1 to 1: 3 based on the first layer 100.

Preferably it may be formed in a ratio of 1: 0.5 to 1: 2, and most preferably may be formed in a ratio of 1: 1 to 1: 1.5, but is not limited thereto.

If the thickness ratio is formed to be less than 1: 0.1 based on the first layer 100, the thickness of the second layer 200 is thin, and the moisture of the skin is reduced by the components of the first layer 100. There is a disadvantage.

In addition, when the thickness ratio is formed in a ratio of 1: 3 or more based on the first layer 100, the thickness of the second layer 200 is formed to be thick, not only to increase the manufacturing cost but also to adhere or fix the final manufactured sheet. It is difficult to make.

Next, the third layer 300 may be formed on one side of the second layer 200, and one or more microneedle may protrude in one direction.

In more detail, the third layer 300 may include the support 301, the microneedle 302, and the adhesive layer 303.

In this case, the support 301 may be formed on one side of the second layer 200 to support the microneedle 302.

The material accommodated in the microneedle 302 by the support 301 may be separated from the outside or may not be absorbed by the second layer 200.

The microneedle 302 may protrude in one direction on one side of the support 301.

That is, the support 301 and the microneedle 302 are formed on one side of the second layer 200 to protrude so that the microneedle 302 may be located inside the skin, thereby forming a material formed inside the microneedle 302. It can be absorbed directly into the skin to improve wrinkles of the user.

Preferably, any one selected from the support 301 or the microneedle 302 is chitosan, collagen, gelatin, hyaluronic acid (HA), starch, cellulose; Polylactic acid, polyglycolic acid and copolymers thereof; Polyethylene oxide, polyacrylic acid, polyacrylamide, polyvinyl alcohol, polyaniline, polypyrrole, polythiophene; And polymers containing carbon black or metal powder; It may be formed of any one selected from.

Preferably, it may be made of hyaluronic acid, but is not limited thereto.

Hyaluronic acid is a biosynthetic natural substance that is present in many skins such as animals. It is a hydrophilic substance because of many hydroxyl groups (-OH), and belongs to a carbohydrate called glucosaminoglycan and has an amine group and a carboxyl group. It attracts a lot of water and is said to have excellent moisturizing abilities.

Since the support 301 or the microneedle 302 formed of such a material penetrates into the skin, the material formed inside the microneedle 302 is easily absorbed into the skin, thereby improving the wrinkles of the user.

Furthermore, the microneedle 302 may include any one selected from vitamin C, peptides, proteins, caffeine, salicylic acid, stem cells, drugs or cosmetic ingredients to improve wrinkles of the user.

Optionally, plant extracts, including Schisandra chinensis extract, pomegranate extract, pomegranate root extract, hollyhock extract, hollyhock extract, etc., fermented by lactic acid bacteria known to be effective for wrinkle improvement, may be further included. Of course not.

Next, in the third step S130, a step of forming the first layer 100 on a surface of the sheet that has passed through the second step S120 may not be performed.

That is, the second layer 200 is formed in a liquid or semi-solid state on the upper side of the release paper, and the first layer 100 is formed on the upper side thereof.

Optionally, when the position at which one selected from the support 301 or the microneedle 302 of the third layer 300 of the sheet to be finally formed is formed transparently, the support of the first layer 100 ( The third step S130 may be performed after further performing a process of cutting the position at which one selected from the 301 or the microneedle 302 is formed.

As such, after forming the existing first layer 100, unlike the method of coating the second layer 200, it is manufactured in a reverse order so that the interface is not bumpy, thereby maintaining uniform physical properties. .

Next, the fourth step (S140) may be formed so that one side and the other side is flattened by pressing the sheet passed through the third step (S130) between two or more rollers.

In this case, the distance between the rollers may be formed in a ratio of 1: 0.1 to 1: 3, based on the first layer 100, as the thickness ratio of the first layer 100 and the second layer 200 is described above. It may be carried out so as to, but is not limited to this.

Furthermore, the speed at which the sheet passed through the third step S130 passes through the roller may be performed at less than 100 mm / s.

If it is performed at a speed of 100mm / s or more, there is a disadvantage that it is difficult to maintain the uniform physical properties of each layer by the passing speed of the sheet.

Next, the fifth step (S150) may be a step of drying the sheet passed through the fourth step (S140) by a dryer.

By performing the fifth step (S150), there is an advantage in that the third layer 300 can be stably seated on one side of the second layer 200.

At this time, the drying temperature of the fifth step (S150) may be dried for 10 to 600 seconds at 30 ~ 100 ℃, but is not limited thereto.

If the drying temperature is carried out below 30 ℃, the drying temperature is too low to take a long time to dry, and when carried out at 100 ℃ or more, the cross section of the sheet finally produced by the high temperature is uniform There is a disadvantage that it does not dry.

Furthermore, when the drying time is less than 10 seconds, there is a disadvantage that the sheet is not easily dried by a short drying time, and when the drying time is longer than 600 seconds, the final process time is long due to a long drying time. There are disadvantages.

Next, the sixth step (S160) is a step of removing the release paper of the sheet having passed through the fifth step (S150), and forming a third layer 300 including the microneedle 302 on the surface from which the release paper is removed. Can be performed.

In this case, an adhesive may be applied in order for the third layer 300 to be easily fixed to one side of the second layer 200.

The pressure-sensitive adhesive is a biocompatible pressure sensitive adhesive of any one selected from the group consisting of silicone, polyurethane, hyaluronic acid, physical adhesive (gecko), polyacrylic, ethyl cellulose, hydroxy methyl cellulose, ethylene vinyl acetate and poly isobutylene, and the like. Can be used.

Obviously, the sixth step S160 may be adhered using a known method.
