Ultraviolet curing type nail polish glue packaging bag and manufacturing method thereof

Abstract

The invention relates to an ultraviolet curing type nail polish glue packaging bag, which is used for injecting and packaging ultraviolet curing type nail polish glue with various colors through one packaging bag and realizing the purpose that the inherent color of contents can be recognized without an independent mark. The present invention greatly reduces costs and improves product competitiveness by eliminating a plurality of work steps and costs generated in a manufacturing process. The ultraviolet-curable nail polish packaging bag of the present invention comprises: a main body part (10) into which ultraviolet-curable nail polish is stored and into which a brush can be inserted or into which the ultraviolet cannot penetrate; and a transparent window part (20) which stores the same nail polish as the nail polish stored in the main body part so as to achieve the purpose that the nail polish having the same color as the nail polish stored in the main body part can be seen from the outside, and a boundary line (30) formed by joining the front and rear pocket pieces is formed between the main body part and the transparent window part. Therefore, the nail polish glue stored in the body part and the transparent window part is prevented from being mixed with each other.

Description

Technical Field

[0001] The present invention relates to a packaging bag for an ultraviolet curable nail polish glue, and more particularly to an ultraviolet curable nail polish glue packaging bag that can prevent the nail polish glue contained in the bag from deteriorating due to ultraviolet rays while allowing the actual color of the nail polish glue to be confirmed from the outside. Background Art

[0002] The content of this part only provides background information related to the content of this application and does not necessarily belong to the prior art.

[0003] Generally, nail polish glue for manicure (toenails) needs to harden within a short time after being applied to the nails to ensure that the glue is not stuck to the surrounding area, so ultraviolet curable glue is used. If an ultraviolet lamp is irradiated after applying the nail polish glue to the nails, it will cure between a few seconds and 1 to 2 minutes according to conditions such as the distance and angle from the light source and the thickness of the glue application.

[0004] Therefore, a nail polish glue container containing ultraviolet curable nail polish glue will use an opaque container that cannot be penetrated by ultraviolet light to ensure that the nail polish glue does not deteriorate due to the surrounding environment. If the nail polish glue container is transparent, even if the ultraviolet lamp is not directly irradiated, the glue in the container will cure due to the light of the ultraviolet wavelength emitted from the fluorescent lamp or sunlight, and it will harden during the circulation process or the storage process of the user before use, resulting in unusability. Therefore, in order to protect the contents, an opaque container has to be manufactured to prevent the penetration of ultraviolet light, which results in the inability to identify the contents inside the container.

[0005] Therefore, so far, the nail polish glue has been made into an ultraviolet curable type, and the container uses an opaque glass bottle that blocks light in a way that ultraviolet rays cannot penetrate. After putting the nail polish glue, the color of the contents is indicated outside the container by several recognizable methods for consumers to select the desired color. For example, the outside of each nail polish glue container is painted with the same color as the contents, or a colored sticker is pasted, or a plastic bottle cap injection molded in the same color is used.

[0006] On the other hand, since nail polish glue is used for manicure, in order to decorate the nails more beautifully, each manufacturing company manufactures and sells hundreds or thousands of colors of nail polish. If the color of the contents is separately indicated outside the packaging container like this, the workload will become very large, resulting in a large amount of inventory, which will become a problem of increasing product costs due to the need to spend a large amount of money.

[0007] Since the nail polish glue for manicure is quickly cured by irradiating ultraviolet rays on the glue applied to the nails, the packaging container for storing it will prevent ultraviolet rays from penetrating into the container except when using the nail polish glue, thereby preventing the contents from curing and maintaining the marketability. Existing nail polish glue containers use opaque glass bottles or solvent-resistant opaque plastic bottles through which light cannot penetrate. Since such containers are made opaque, the contents inside cannot be seen from the outside of the container. However, although the color of the contents is a very important part for consumers of nail polish glue, the color of the contents cannot be seen. As a countermeasure, manufacturers separately print a color close to that of the contents and attach it to the outside of the packaging container. When using a solvent-resistant opaque plastic container, the container itself is injection-molded in a color similar to that of the contents, or an epoxy sticker with a similar color is pasted on the surface of the container.

[0008] The nail polish glue is used for manicure. To meet the desires of consumers who want to decorate their nails more beautifully, it is made in multiple colors of multiple types. As the opaque container is used in the packaging of nail polish glue in the above-mentioned manner, it is necessary to separately label the color on the outside to indicate the color, which will cause many problems and high costs. In addition, there is a drawback that the color of the printed matter separately attached to the outside is difficult to be exactly the same as the color of the contents.

[0009] Even though the ultraviolet-curable nail polish glue has the above-mentioned drawbacks, the reasons for not making it into a heat-curable or air-dryable glue are as follows.

[0010] During the manicure process, after applying the glue of the required color on the nails, it is necessary to quickly cure it to ensure that the glue does not stick to the surrounding area. However, for heat-curable nail polish glue, when heat is applied to the nails, the hands will become too hot to use. For air-dryable nail polish glue, there are problems such as too long drying and curing time, requiring a long waiting time, and sticking to the surrounding area and polluting the surrounding area before the curing is completed, so it is not actually used. On the contrary, if an ultraviolet lamp is irradiated after applying the ultraviolet-curable nail polish glue, it will be cured immediately after application, and the application process will end, thus maximizing the convenience in use.

[0011] Moreover, in the past, the color of the contents was separately labeled on the outside of the packaging container, which would result in various operations and a large amount of inventory, consuming a large amount of costs. As an example, if the basic order quantity for a single printing of a colored sticker of one color to be attached to the packaging surface is 8 Km, even if there are only 100 colors, 800 Km needs to be printed, and this is not all shipped at once, so a large amount of inventory will be generated. The same is true for opaque containers made by plastic injection molding. Since there is a basic quantity for injection molding in one color, even if only 100 are injection-molded, a large quantity needs to be injection-molded, so a large amount of costs and time will be consumed due to inventory.

[0012] Korean Utility Model Registration No. 20-0475031 relates to a nail art container having a nail art sample labeling function. The nail art container includes: a container body that internally houses a nail art solution; and a cap portion that seals an entrance of the container body. The nail art container having the nail art sample labeling function is characterized in that it includes: a glitter sticker having adhesive layers formed on both sides so as to be attachable to an outer surface of the container body or the cap portion; a plurality of decorative members adhesively fixed to a surface of the glitter sticker, provided with a sample coating and a nail art sample member, the sample coating being formed by applying the same nail art solution as the nail art solution in the container body on one side of the surface of the glitter sticker, and the nail art sample member being composed of a transparent coating applied and cured on the sample coating to protect the surface; and a second decorative member having an outer shape larger than that of the decorative member and used for attaching a sample label between the decorative members, and the nail art sample member is formed on a surface of the second decorative member, and the sample coating does not completely present the nail art solution in the container body.

[0013] Korean Patent Publication No. 10-2017-0050892 relates to a storage container for a gel-type liquid substance, which includes: a container portion having an entrance portion formed at an upper portion and a storage space formed therein for storing a liquid for gel nails; and a lid portion made of a transparent material, provided with a support rod having a brush at a lower portion, and at least a part of a peripheral surface thereof is formed with a coating having a color corresponding to the liquid so as to be recognizable from the outside. In order to prevent ultraviolet rays of the liquid stored inside the container portion from leaking to the outside, the entire container portion is formed of an opaque material, and an opaque barrier layer is formed on an outer peripheral surface or an inner peripheral surface, and it can be recognized from the outside through the coating having a color corresponding to gel nails, but the coating may be different from the gel nails inside, and in terms of the overall structure, the manufacturing cost is high.

[0019] Technical Problem

[0020] The present invention is used to solve the above-mentioned problems, and the object of the present invention is to provide the following ultraviolet curable nail polish glue packaging bag. By injecting and packaging multiple colors of ultraviolet curable nail polish glue through one package, it can be recognized without separately indicating the original color of the content, thereby eliminating multiple operations and costs generated during the manufacturing process, and improving the competitiveness of products by significantly reducing costs.

[0021] Technical solution

[0022] The ultraviolet curable nail polish glue packaging bag of the present invention is characterized in that it includes: a body part that stores ultraviolet curable nail polish glue inside and can discharge the nail polish glue inside or can insert a brush, and ultraviolet rays cannot penetrate; a transparent window part that stores the same nail polish glue as the nail polish glue stored in the body part so that the same color as the nail polish glue stored in the body part can be seen from the outside; and a boundary line formed by joining the two sides of the bag, formed between the body part and the transparent window part to prevent the nail polish glue stored in the body part and the nail polish glue stored in the transparent window part from mixing with each other.

[0023] The present invention is characterized in that the ultraviolet curable nail polish glue packaging bag is formed by overlapping two bag pieces and joining the edge parts, and the boundary line is formed between the body part and the transparent window part after injecting nail polish glue between the two bag pieces, or the boundary line is first formed between the body part and the transparent window part and then nail polish glue is injected into the body part and the transparent window part respectively.

[0024] Effects of the invention

[0025] According to the ultraviolet curable nail polish glue packaging bag of the present invention, the packaging container for nail polish glue is formed in a bag shape, and is packaged in a form that is divided into a part (body part) that is completely not affected by ultraviolet rays after injecting nail polish glue and a transparent window part that is affected by ultraviolet rays but the color of the content can be recognized by the naked eye. Therefore, a discharge part (such as a spout) can be formed in the part that is not affected by ultraviolet rays to use high-quality nail polish glue that is not cured by ultraviolet rays through the spout. At the same time, the original color of the content can be directly recognized by the naked eye through the transparent window part, thereby having the effect of enabling the user to confirm the actual color of the content and improving the reliability of the product.

[0026] In this case, the nail polish glue in the transparent window part may be cured by ultraviolet rays. Since the content in the cured state will be presented, it can also present the state after the nail polish glue is cured on the nails, eliminating the misunderstanding that the color of the content may be different from the color after use. Although the nail polish glue in the transparent window part is cured by the influence of ultraviolet rays, this part of the nail polish glue will not be used and will not be mixed with the nail polish glue in the main body part. Therefore, it has nothing to do with the physical properties of the nail polish glue in the main body part.

[0027] Moreover, since there is no need to perform all the operations that were previously done to separately label the color of the content outside the opaque nail polish glue container, there is a huge cost reduction effect.

[0028] In addition, it has the effect of eliminating the problem that the color of the printed matter or plastic container attached separately to the outside is not exactly the same as the color of the content in the bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Hereinafter, in the process of describing the present invention, if it is judged that the specific description of related well-known functions or structures may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Moreover, the following terms are terms defined in consideration of the functions in the present invention, and these may vary according to the intentions or conventions of users, application personnel, etc. Therefore, their meanings should be defined based on the entire content of the specification.

[0042] As Figure 1 and Figure 2 shown, the packaging bag 100 for an ultraviolet-curable nail polish glue according to the present invention (hereinafter simply referred to as "bag") is characterized in that a boundary line 30 is thermally bonded between the main body part 10 and the transparent window part 20 so that even when the same contents (nail polish glue) are contained in the main body part 10 and the transparent window part 20, they do not mix with each other.

[0043] Multiple embodiments of the present invention can be described as follows. In the following embodiments, the same contents are contained in the main body part 10 that is impermeable to ultraviolet rays and the transparent window part 20 through which the contents can be confirmed from the outside. The main body part 10 and the transparent window part 20 are divided by the boundary line 30 so that the contents do not mix with each other, and the edges are bonded.

[0044] The main body part 10 is formed of an opaque sheet, and the transparent window part 20 is formed of a transparent sheet.

[0045] Embodiment 1

[0046] As Figure 1 andFigure 2 As shown, in this embodiment, a spout 11 and a lid 12 are provided in the main body 10 in a manner that allows the use of the contents. The nail polish glue can be extruded through the spout 11 for use or applied with a brush.

[0047] And, as an example, the bag piece forming the main body 10 can be made of a laminated aluminum foil and polyethylene terephthalate (PET) film in a film-like form, so that ultraviolet rays cannot penetrate.

[0048] On the contrary, the transparent window portion 20 can be realized by using only a transparent sheet (such as a polyethylene terephthalate (PET) film) to enable the color of the contents to be visually seen.

[0049] The polyester film as the transparent sheet is a material with a small thermal shrinkage rate under high temperature and high humidity conditions and little shrinkage and deformation during processing such as lamination, coating, and printing.

[0050] The transparent window portion 20 prevents the nail polish glue from mixing with each other by distinguishing the main body 10 and the boundary line 30. It can be formed at any position of the main body 10, preferably formed on the inner side adjacent to the edge (end) of the bag. And it is formed horizontally at the bottom of the main body 10 and extends vertically along the side of the main body 10. The formation position of the boundary line 30 depends on the positions of the main body 10 and the transparent window portion 20.

[0051] And, a large spout 11 is thermally bonded to the upper side of the main body 10. The diameter of the entrance of the spout 11 is also formed in a structure that allows the brush to fully enter. Therefore, the brush can be placed inside the bag and dipped in the nail polish glue for use.

[0052] Embodiment 2

[0053] As Figure 3 shown, in this embodiment, the plug portion 13 is formed integrally at the upper end of the spout 11. When first used, by grasping the two blades 13a of the plug portion 13 and turning, the plug portion 13 at the upper end can be separated from the position with the separation groove 11a, thus opening the hole of the spout 11.

[0054] Through this hole, the nail polish glue is squeezed onto the nails and evenly spread and applied with a brush, and then cured with an ultraviolet lamp to complete the manicure. If there is a remaining amount after using the nail polish glue, the plug portion 13 is inverted and the lid pin portion 13b formed on the upper part of the plug portion 13 is buckled into the hole of the spout 11, and it is stored in a manner that the nail polish glue in the main body 10 does not leak.

[0055] In this embodiment, the transparent window portion 20 is located at the lower corner of the main body 10 and is divided by the boundary line 30.

[0056] Embodiment 3

[0057] In Figure 4 and Figure 5 In the embodiment shown, a brush-cum-lid 14 is provided which has a hole capable of opening and closing the mouth portion 11 and is integrally formed with a brush.

[0058] A brush 14a is provided at the lower end of the brush-cum-lid 14. Thus, in the state where the brush-cum-lid 14 is screwed on, the brush 14a will remain inside the bag through the hole of the mouth portion 11 and will always be coated with nail polish glue. Therefore, the nail polish glue can be directly used after unscrewing the brush-cum-lid 14.

[0059] Also, a hanging hole portion 15 may be provided at the lower end of the bag 100. The hanging hole portion 15 is used to hang and store the bag 100, and one or more may be formed anywhere in the edge portion of the bag 100.

[0060] Embodiment 4

[0061] As Figure 6 shown, the bag 100 of this embodiment forms a (flat) bottom surface 17 at the lower part to enable more content to be filled inside the main body portion 10, and the bag 100 can stand upright.

[0062] In the case of having the bottom surface 17, it is preferable to dispose the transparent window portion 20 at the upper part, in the corner portion formed on the left or right side of the upper part.

[0063] Embodiment 5

[0064] As Figure 7 shown, the bag 100 of this embodiment forms a nozzle portion 16 without a separate plastic spout. On one side of the main body portion 10, the nozzle portion 16 which protrudes in a form towards a part of the edge of the main body portion 10 is integrally formed.

[0065] The nozzle portion 16 is used by squeezing out the nail polish glue after cutting the end portion (dotted line) with scissors or the like.

[0066] The bag 100 of this embodiment is mainly suitable for use as a disposable container. When there is a surplus, the nozzle portion 16 is clamped with a clip or the like to store the content without leakage. The transparent window portion 20 is located at the opposite corner of the nozzle portion 16 and is divided from the main body portion 10 by an inclined boundary line 30.

[0067] In the present invention, after punching out a shape designed in the shape of a window at an appropriate position on a sheet made of a film-shaped aluminum foil and a polyethylene terephthalate (PET) film laminated and removing it, a bag with a transparent window portion 20 is made again using a material laminated with a transparent film.

[0068] The transparent window portion 20 can form a transparent window on only one side of the bag or can form transparent windows on both sides. The transparent windows formed on both sides can be seen through from the front side to the back side of the bag by aligning the positions.

[0069] As another method, by bonding a transparent sheet larger in size than the bag sheet made of an opaque material, a portion protruding more than the bag sheet is formed as the transparent window portion. The width obtained by adding the width in the longitudinal direction of the main body portion made of a sheet that is impermeable to ultraviolet rays and is composed of an aluminum foil and a polyethylene terephthalate (PET) film in the form of a laminated film and the width of the transparent portion is used to re-laminate the transparent film (Lamination) and finally used for the production of the bag. Thus, the width portion of the sheet that is impermeable to ultraviolet rays is used as the main body portion, and the portion laminated with the transparent film in a manner wider than the width of the original sheet is used as the transparent window portion.

[0070] The above-mentioned mouth portion 11, lid 12, integral mouth portion 11 with lid pin portion, brush-cum-lid 14, and nozzle portion 16 are multiple embodiments of the opening unit.

[0071] Hereinafter, the manufacturing process of the bag of the present invention will be described.

[0072] Example 1 (refer to Figure 8 )

[0073] 1. Manufacturing an open bag

[0074] A bag 100 having an opening portion 110 formed on one side is manufactured for injecting nail polish glue.

[0075] This state belongs to the state where the edge portions of the bag sheets are bonded to form an opening portion 110 on the opposite side of the mouth portion 11. Therefore, although there are a main body portion 10 and a transparent window portion 20, they are in a mutually communicating state.

[0076] 2. Injecting nail polish glue

[0077] Through the opening portion 110 of the bag 100, the injection port of the nozzle 200 is inserted into the main body portion 10 and nail polish glue is injected.

[0078] Since it is a single space where the main body portion 10 and the transparent window portion 20 are in a mutually communicating state, the nail polish glue is injected without partitioning the main body portion 10 and the transparent window portion 20.

[0079] After the injection of the nail polish glue is completed, the opening portion 110 is sealed in the same manner as the sealing method (thermal bonding (welding)) of the edge portion, thereby forming a sealing portion 111.

[0080] 3. Forming a boundary line

[0081] Bond (thermally bond) the two sides of the bag between the main body portion 10 and the transparent window portion 20 to form a boundary line 30. In this way, based on the boundary line 30, the main body portion 10 and the transparent window portion 20 are divided in a separated state from each other. Therefore, a larger amount of nail polish glue will be contained in the main body portion 10, and a part of the nail polish glue will be contained in the transparent window portion 20.

[0082] When joining the boundary line 30, even if there is nail polish glue between the two sides of the bag, the joining can be carried out, so that the nail polish glue in the main body portion 10 and the transparent window portion 20 does not mix with each other.

[0083] Example 2 (refer to Figure 9 )

[0084] 1. Manufacture the bag

[0085] The manufacturing method of this embodiment is as follows. That is, two opening portions 110-1 and 110-2 are formed on the bag 100. The first opening portion 110-1 is an opening portion communicating with the main body portion 10, and the second opening portion 110-2 is an opening portion communicating with the transparent window portion 20. Therefore, the main body portion 10 and the transparent window portion 20 are divided by the boundary line 30, and are in a state where only the respective opening portions 110-1 and 110-2 are open.

[0086] 2. Inject the nail polish glue

[0087] The nozzle 200 includes a first nozzle portion 210 and a second nozzle portion 220 that respectively inject the nail polish glue into the first opening portion 110-1 and the second opening portion 110-2. In this case, since the amount of the nail polish glue injected into the transparent window portion 20 is less than the amount injected into the main body portion 10, the diameter of the second nozzle portion 220 for injecting the nail polish glue into the transparent window portion 20 is smaller than the diameter of the first nozzle portion 210 for injecting the nail polish glue into the main body portion 10.

[0088] Inject the nail polish glue into the main body portion 10 and the transparent window portion 20 respectively through the first nozzle portion 210 and the second nozzle portion 220.

[0089] 3. Seal

[0090] Seal the first opening portion 110-1 and the second opening portion 110-2 formed in the main body portion 10 and the transparent window portion 20.

[0091] The following Example 3 and Example 4 are manufacturing methods using the structure (such as the mouth portion) for injecting the nail polish glue, etc. The size of the mouth portion is formed to be the size (the size into which the nozzle can be inserted) that can inject the nail polish glue through the nozzle of the injector.

[0092] Example 3 (refer to Figure 10 )

[0093] 1. Manufacture the bag

[0094] A bag is manufactured by sealing the edge portions of two bag sheets before and after and joining a mouth portion 11 on one side. In this case, the main body portion 10 and the transparent window portion 20 are not divided.

[0095] 2. Inject nail polish glue

[0096] Insert a nozzle 200 into the mouth portion 11 to inject nail polish glue into the interior of the bag.

[0097] 3. Form a boundary line

[0098] Join (thermally bond) the two bag sheets between the main body portion 10 and the transparent window portion 20 to form a boundary line 30. In this way, based on the boundary line 30, the main body portion 10 and the transparent window portion 20 are divided in a state of being separated from each other. Therefore, a larger amount of nail polish glue will be contained in the main body portion 10, and a part of the nail polish glue will be contained in the transparent window portion 20.

[0099] When joining the boundary line 30, even if there is nail polish glue between the two bag sheets, joining can be achieved, so the nail polish glue in the main body portion 10 and the transparent window portion 20 will not be mixed with each other.

[0100] Example 4 (refer to Figure 11 )

[0101] 1. Manufacture a bag

[0102] Seal the edge portions of two bag sheets before and after and join a mouth portion 11 on one side. Form a boundary line 30 by joining between the main body portion 10 and the transparent window portion 20, and form an opening portion on one side of the transparent window portion 20. Therefore, the main body portion 10 and the transparent window portion 20 will be in a non-connected state through the boundary line 30.

[0103] 2. Inject nail polish glue

[0104] Use the nozzle 200 described in Example 2 to inject nail polish glue into the main body portion 10 and the transparent window portion 20 respectively. The first nozzle portion 210 will be inserted into the main body portion 10 through the mouth portion 11, and the second nozzle portion 220 will be inserted into the transparent window portion 20 through the opening portion. In this state, nail polish glue will be injected into the main body portion 10 and the transparent window portion 20 respectively.

[0105] 3. Seal

[0106] Seal by combining the mouth portion 11 and the lid 12, and seal the opening portion of the transparent window portion 20 by thermal bonding.

[0107] Hereinafter, a modification example of the present invention will be described.

[0108] As described above, although the boundary line 30 as a whole divides the main body portion 10 and the transparent window portion 20, however, asFigures 12 to 14 As shown, the boundary line 30 of the present invention can also be composed of a blocking portion 31 and a connecting portion 32.

[0109] The blocking portion 31 refers to the blocking part that prevents the nail polish glue in the main body portion 10 from flowing into the transparent window portion 20, and the connecting portion 32 refers to the passage that allows a small amount of the nail polish glue in the main body portion 10 to flow into the transparent window portion 20.

[0110] According to the structure of the connecting portion 32, when joining the edge portions of the bag pieces, a bag is manufactured by simultaneously joining the blocking portion 31 of the boundary line 30. Even if the nail polish glue is injected through a single process, the nail polish glue will be injected into the transparent window portion 20 through the connecting portion 32. Therefore, the manufacturing process can be reduced. As ultraviolet rays are irradiated on the transparent window portion 20 of the plastic bag 100 manufactured in the above-described manner, a small amount of the nail polish glue in the transparent window portion 20 is immediately cured, and it not only cannot flow into the main body portion 10, but also has no impact.

[0111] As shown in the figure, forming more than one connecting portion 32 on the boundary line 30 is not limited to being formed at the end of the boundary line, and can also be formed in the middle or at both ends of the boundary line 30, and there can be various ways.

[0112] And, as Figure 15 shown, the present invention does not form an additional boundary line 30. As ultraviolet rays are irradiated on the transparent window portion 20, only the nail polish glue irradiated with ultraviolet rays is cured. Thus, the nail polish glue 1-1 in the main body portion 10 and the nail polish glue 1-2 in the transparent window portion 20 can be distinguished.

[0113] Hereinafter, the manufacturing method will be described. The inside of the bag is a single space, that is, the main body portion 10 and the transparent window portion 20 are not distinguished. If nail polish glue is injected into the inside of the bag, the nail polish glue gradually fills the lower transparent window portion 20 and is stored in the main body portion 10.

[0114] Next, while pressing the transparent window portion 20 to make it thinner, ultraviolet rays are irradiated. Then, the ultraviolet rays pass through the transparent window portion 20 to cure the nail polish glue in the transparent window portion 20. Thus, the cured nail polish glue 1-2 does not mix with the liquid nail polish glue 1-1 in the main body portion 10 and shows the color on the outside. That is, although there is no additional boundary line, the nail polish glue exists in the main body portion 10. In order to show the liquid nail polish glue 1-1 used by the user and the nail polish glue 1-1 in the main body portion 10, the nail polish glue 1-2 exposed to the outside is distinguished through the transparent window portion 20.

[0115] There are many specific methods for irradiating ultraviolet rays onto the transparent window portion 20, for example, a method of pressing the outer contour of the transparent window portion 20 with a clamp having the same shape as the outer contour of the transparent window portion 20 and irradiating ultraviolet rays onto the transparent window portion 20 through the hollow portion of the clamp, a method of pressing only the portion connected to the main body 10 from one side of the transparent window portion 20 and irradiating ultraviolet rays onto the transparent window portion 20, a method of irradiating ultraviolet rays while pressing the transparent window portion 20 with a transparent plate through which ultraviolet rays can pass, etc.

[0116] Furthermore, the present invention can realize not only a bag sheet having flexibility, but also a sheet and molding (convex shape processing) that can maintain a three-dimensional convex shape even when nail polish is not injected inside.
