Description
A method for folding a fine or ultra-fine face maskFIELD OF THE INVENTION
[0001] The present invention relates to a method for folding a fine or ultra-fine face mask, a fine or ultra-fine face mask product, and a method for producing the fine or ultra-fine face mask product.BACKGROUND OF THE INVENTION
[0002] Fine or ultra-fine face masks refer to face masks made of fine fibers or ultra-fine fibers. The single-filament fineness of fine fiber is usually 1.0-0.5D, while the single-filament fineness of ultra-fine fiber is usually 0.5-0.1D. The definition of fineness D is the number of grams of weight for 9000 meters in length of the yarn or fiber. Face masks made of fine fiber or ultra-fine fiber have the advantages of high softness, better skin fit, and a long-lasting moisture-locking effect.
[0003] For the tissue of fine or ultra-fine face masks, because its material is extremely thin and soft, it is easy to wrinkle and adhere to each other during the folding and / or unfolding process, two liners are usually used in the folding process of the face mask to sandwich a piece of fine or ultra-fine tissue in the middle of the two liners to create a sandwich-like structure. This structure provides sufficient support and protection for the fine or ultra-fine tissue. No matter how the face mask is folded during the folding process, there will be no wrinkles or adhesion problems for the tissue.
[0004] However, a disadvantage of using two liners is that the user must remove one of the liners before applying the face mask to the face, and remove the other liner after applying the face mask. Such cumbersome operations are very unfriendly to users. In addition, the two liners also increase additional manufacturing costs. On the one hand, the use of two liners increases the amount of plastic used in the product; on the other hand, the use of two liners is not conducive to the soaking of the mask in the liquid cosmetic nutrient solution, and more liquid cosmetic nutrient solution needs to be filled in the mask packaging bag.
[0005] The proposal of eco-responsible and environmentally friendly solutions which are designed and developed considering environmental issues is becoming a major goal in an effort to meet global challenges. It is therefore essential to design more sustainable products that reduce the amount of materials used, replace existing materials with greener materials and use recyclable materials in order to reduce the carbon footprint of the products.
[0006] In this context, it is important to develop packaging that generates less waste, more specifically by redesigning packaging to reduce the amount of plastic used in the product.
[0007] For this reason, the inventor of the present invention sought the possibility of using only one liner in a fine or ultra-fine face mask during the product development. However, the problem with using only one piece of liner is that when folding the face mask, it is difficult to avoid adhesion caused by the contact between the tissue portions of the same tissue. This technical problem makes it difficult to use only one liner when manufacturing face mask products.SUMMARY OF THE INVENTION
[0008] To solve the above technical problem, according to the first aspect of the present invention, a method suitable for folding a fine or ultra-fine face mask having only one piece of liner is proposed. The method according to the first aspect of the present invention can reduce the mutual contact area between the tissue portions of the same tissue, thereby significantly reducing the possibility of the tissue portions adhering to each other.

[0016] Preferably, in the first step, placing the face mask flat with the liner perfectly fitted.
[0017] Preferably, the face mask has exactly two longitudinal lines extending parallel to the longitudinal direction of the face mask, and the face mask is divided into a first longitudinal area, a second longitudinal area, and a third longitudinal area having substantially the same width by the first longitudinal line and the second longitudinal line, wherein in the second step, the first longitudinal area is folded inwardly along the first longitudinal line so that the first longitudinal area is located above the second longitudinal area; and the third longitudinal area is folded inwardly along the second longitudinal line so that the third longitudinal area is located above the folded first longitudinal area.
[0018] Preferably, the face mask has exactly three longitudinal lines extending parallel to the longitudinal direction of the face mask, and the face mask is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area and a fourth longitudinal area having substantially the same width by the first longitudinal line, a second longitudinal line and a third longitudinal line. wherein, in the second step, the first longitudinal area is folded inwardly along the first longitudinal line so that the first longitudinal area is above the second longitudinal area; the fourth longitudinal area is folded inwardly along the third longitudinal line so that the fourth longitudinal area is above the third longitudinal area; the folded first longitudinal area or the folded fourth longitudinal area is folded along the second longitudinal line so that the first longitudinal area contacts the fourth longitudinal area.

[0020] Preferably, the face mask has exactly five longitudinal lines extending parallel to the longitudinal direction of the face mask, and the face mask is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area, a fourth longitudinal area, a fifth longitudinal area and a sixth longitudinal area having substantially the same width by the first longitudinal line, the second longitudinal line, the third longitudinal line, the fourth longitudinal line and the fifth longitudinal line, wherein, in the second step, the first longitudinal area is folded inwardly along the first longitudinal line so that the first longitudinal area is located above the second longitudinal area; the folded first longitudinal area is folded inwardly along the second longitudinal line so that the first longitudinal area contacts the third longitudinal area; the sixth longitudinal area is folded inwardly along the fifth longitudinal line so that the sixth longitudinal area is located above the fifth longitudinal area; the folded sixth longitudinal area is folded inwardly along the fourth longitudinal line so that the sixth longitudinal area contacts the fourth longitudinal area; the folded second longitudinal area or the folded fifth longitudinal area is folded along the third longitudinal line so that the second longitudinal area contacts the fifth longitudinal area.
[0021] Preferably, the face mask has three to five longitudinal lines, wherein, in the second step, the face mask is folded in the same direction along each longitudinal line in sequence so that the width of the folded face mask corresponds to the width of one longitudinal area.

[0030] Preferably, the tissue is made of ultra-fine fiber with a fineness of less than 0.5D, more preferably less than 0.3D. Because this kind of tissue is very thin and soft, it is generally believed that two pieces of liners must be used to effectively prevent it from wrinkling and adhering. By using the folding method according to the first aspect of the present invention, wrinkles and adhesion of the tissue can be effectively prevented even with only one piece of liner.
[0031] According to the second aspect of the present invention, a fine or ultra-fine face mask product is proposed, which has a face mask packaging bag and a face mask.

[0033] Preferably, in the face mask packaging bag, the liquid cosmetic nutrient solution and the face mask are isolated from each other. Only before applying the mask to the face, do they contact each other by squeezing the liquid cosmetic nutrient solution into the mask area.

[0037] - the third step, filling the liquid cosmetic nutrient solution into the face mask packaging bag.
[0038] Other features and advantages of the present invention will be apparent from the following more detailed description of the illustrative embodiment, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In FIGS. 1 to 7, each longitudinal line is referred to as the first longitudinal line, the second longitudinal line, the third longitudinal line, the fourth longitudinal line and the fifth longitudinal line from left to right. Each longitudinal area is referred to as the first longitudinal area, the second longitudinal area, the third longitudinal area, the fourth longitudinal area, the fifth longitudinal area and the sixth longitudinal area from left to right. Each transversal area is referred to as the first transversal area and the second transversal area from top to bottom.
[0048] FIG. 1 shows a top view of a fine or ultra-fine face mask 1 according to the present invention. Before starting to fold, the mask 1 is placed flat on a horizontal or slightly tilted countertop. The folding of the mask 1 can be done manually by workers or through specialized automated equipment in a factory.
[0049] The face mask 1 in FIG. 1 has a piece of fine or ultra-fine tissue 3 and a piece of liner 2, and the tissue 3 and the liner 2 are overlapped up and down and contact each other. In the embodiment shown in FIG. 1, the liner 2 is located on the top of the tissue 3. For the sake of clarity, the liner 2 in FIG. 1-7 is shown in hatching, while the tissue 3 is shown in white. In FIG. 1, the tissue 3 is hidden by the liner 2 and is not visible because the tissues 3 is located under the liner 2. The colors and textures of the tissue 3 and liner 2 in the accompanying drawings do not constitute restrictions on them. In fact, the tissue 3 is usually white or milky white, and the liner 2 is usually white or transparent. In addition, the color of the tissue 3 and liner 2 may depend on the color of the liquid cosmetic nutrient solution adsorbed by the mask 1.
[0050] As shown in FIG. 1, the face mask 1 is divided into a first longitudinal area 111, a second longitudinal area 112 and a third longitudinal area 113 having substantially the same width by a first longitudinal line 110 and a second longitudinal line 120 extending parallel to the longitudinal direction of the mask 1, and the face mask 1 is divided into a first transversal area 161 and a second transversal area 162 having substantially the same length by a first transversal line 160 extending parallel to the transversal direction of the mask 1.
[0051] The first longitudinal line 110, the second longitudinal line 120 and the first transversal line 160 are represented by dot-dash lines in FIG. 1. They are imaginary lines for the purpose of clearly explaining the folding method, and they are not lines that actually exist on the mask 1.
[0052] As shown in FIG. 1, the face mask 1 usually has openings 4 at positions corresponding to the eyes, nose and mouth, through which the mask 1 can be positioned accurately on the human face. The longitudinal and transversal directions of the mask 1 can be determined with the help of the human face. In the context, the longitudinal direction of the mask 1 corresponds to the longitudinal direction of the human face, that is, the direction extending vertically from the center of the forehead to the center of the chin; the transversal direction of the face mask 1 is perpendicular to the longitudinal direction, that is, the direction extending horizontally from one side of the human face to the other side.
[0053] Fig. 2 shows a flow chart of folding a fine or ultra-fine face mask 1 according to the first preferred embodiment of the present invention.
[0054] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Similar to the face mask 1 shown in FIG. 1, the liner 2 is also located above the tissue 3 in FIG. 2. This means that the tissue 3 rests against the countertop while the liner 2 faces away from the countertop.
[0055] In the second step, the first longitudinal area 111 is folded along the first longitudinal line 110 so that the first longitudinal area 111 is located above the second longitudinal area 112. After being folded, the liner 2 at the folded first longitudinal area 111 comes into contact with the liner 2 at the second longitudinal area 112, and the tissue 3 at the folded first longitudinal area 111 faces away from the countertop.
[0056] In the third step, the third longitudinal area 113 is folded along the second longitudinal line 120 such that the folded third longitudinal area 113 is located above the folded first longitudinal area 111. After being folded, the liner 2 at the folded third longitudinal area 113 comes into contact with the tissue 3 at the folded first longitudinal area 111, and the tissue 3 at the folded third longitudinal area 113 faces away from the countertop.
[0057] In the fourth step, the first transversal area 161 is folded along the first transversal line 160 so that the folded first transversal area 161 contacts the second transversal area 162. After folding, the tissue 3 in the folded first transversal area 161 comes into contact with the tissue 3 in the second transversal area.
[0058] The advantage of the folding method according to the first preferred embodiment of the present invention is that the contact area between the tissue portions of the same tissue 3 is reduced, thereby reducing the possibility of the tissue portions adhering to each other. In the embodiment shown in FIG. 2, no contact between the tissue portions occurs during the first step to the third step. Only in the fourth step, i.e., after the first transversal area 161 has been folded relative to the second transversal area 162, the contact between the tissues portions occurs. It can be seen from the fourth step in FIG. 2 that the area of the tissue portion contacting area is only roughly half of the area of the middle area. Considering that after the third step, there are still parts of the liner 2 on the top and bottom of the second longitudinal area 112 facing away from the countertop and are not covered by the folded first and second area 4 and 6, the actual contact area of the tissue portions is smaller. Since the tissue portion contacting area is smaller by this folding method, the possibility of the tissue adhesion is significantly reduced.
[0059] Figure 3 shows a flow chart of folding a fine or ultra-fine face mask 1 according to the second preferred embodiment of the present invention. The only difference between this embodiment and the first embodiment is that the tissue 3 is placed above the liner 2 before folding. The remaining steps are the same as those in the first embodiment.
[0060] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Different from the face mask 1 shown in FIG. 1, the liner 2 is located below the tissue 3 in FIG. 3. This means that the liner 2 rests against the countertop while the tissue 3 faces away from the countertop.
[0061] In the second step, the first longitudinal area is folded along the first longitudinal line 210 so that the folded first longitudinal area is located above the second longitudinal area. After being folded, the tissue 3 at the folded first longitudinal area comes into contact with the tissue 3 at the second longitudinal area, and the liner 2 at the folded first longitudinal area faces away from the countertop.
[0062] In the third step, the third longitudinal area is folded along the second longitudinal line 220 such that the folded third longitudinal area is located above the folded first longitudinal area. After being folded, the tissue 3 at the folded third longitudinal area comes into contact with the liner 2 at the folded first longitudinal area, and the liner 2 at the folded third longitudinal area faces away from the countertop.
[0063] In the fourth step, the first transversal area is folded along the first transversal line 260 so that the folded first transversal area contacts the second transversal area. After being folded, the liner 2 in the folded first transversal area 161 comes into contact with the liner 2 in the second transversal area.
[0064] The folding method according to the second preferred embodiment of the present invention also reduces the contact area between the tissue’s portions, thereby reducing the possibility of the tissue portions adhering to each other. In the embodiment shown in FIG. 3, in the first step, the third step and the fourth step, no contact between the tissue portions occurs. Only in the second step, that is, after the first longitudinal area is folded along the first longitudinal line 210, the contact between the tissues portions occurs. It can be seen from the second step in FIG. 3 that without considering the area of the openings 4 on the mask 1, the area of the tissue portion contacting area roughly corresponds to the area of the first longitudinal area. If the area of the openings 4 on the mask is taken into account, the actual tissue portion contacting area is smaller. Since the tissue portion contacting area is smaller by this folding method, the possibility of the tissue adhesion is significantly reduced.
[0065] In the embodiments of FIGS. 2 and 3, whether the first longitudinal area on the left side or the third longitudinal area on the right side of the figure is first folded in the second step does not affect the realization of the technical effect of the present invention. In the fourth step, whether the first transversal area 161 is folded downward or the second transversal area 162 is folded upward, it does not affect the realization of the technical effect of the present invention.
[0066] In FIGS. 4 to 7, for clarity, except for the first step, the openings for the eyes, nose and mouth on the mask are omitted.
[0067] Fig. 4 shows a flow chart of folding a fine or ultra-fine face mask according to the third preferred embodiment of the present invention. In this embodiment, the face mask 1 has exactly three longitudinal lines 310, 320, 330 extending parallel to the longitudinal direction of the face mask 1, and the face mask 1 is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area and a fourth longitudinal area having substantially the same width by the first longitudinal line 310, the second longitudinal line 320 and the third longitudinal line 330.
[0068] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Similar to the face mask 1 shown in FIG. 1, the liner 2 is also located above the tissue 3 in FIG. 4. This means that the tissue 3 rests against the countertop while the liner 2 faces away from the countertop.
[0069] In the second step, the first longitudinal area is folded inwardly along the first longitudinal line 310 so that the first longitudinal area is above the second longitudinal area.
[0070] In the third step, the fourth longitudinal area is folded inwardly along the third longitudinal line 330 so that the fourth longitudinal area is above the third longitudinal area.
[0071] In the fourth step, the folded fourth longitudinal area is folded along the second longitudinal line 320 so that the first longitudinal area contacts the fourth longitudinal area.
[0072] In the fifth step, the first transversal area is folded along the first transversal line 360 so that the folded first transversal area contacts the second transversal area. After being folded, the liner 2 in the folded first transversal area comes into contact with the liner 2 in the second transversal are a.
[0073] Fig. 5 shows a flow chart of folding a fine or ultra-fine face mask according to the fourth preferred embodiment of the present invention. In this embodiment, the face mask 1 has exactly four longitudinal lines 410, 420, 430, 440 extending parallel to the longitudinal direction of the face mask 1, and the face mask 1 is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area, a fourth longitudinal area and a fifth longitudinal area having substantially the same width by the first longitudinal line 410, the second longitudinal line 420, the third longitudinal line 430 and the fourth longitudinal line 440.
[0074] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Similar to the face mask 1 shown in FIG. 1, the liner 2 is also located above the tissue 3 in FIG. 5. This means that the tissue 3 rests against the countertop while the liner 2 faces away from the countertop.
[0075] In the second step, the first longitudinal area is folded inwardly along the first longitudinal line 410 so that the first longitudinal area is located above the second longitudinal area.
[0076] In the third step, the folded first longitudinal area is folded inwardly along the second longitudinal line 420 so that the first longitudinal area contacts the third longitudinal area.
[0077] In the fourth step, the fifth longitudinal area is folded inwardly along the fourth longitudinal line 440 so that the fifth longitudinal area is located above the fourth longitudinal area.
[0078] In the fifth step, the folded second longitudinal area is folded along the third longitudinal line 430 so that the second longitudinal area contacts the fifth longitudinal area.
[0079] In the sixth step, the first transversal area is folded along the first transversal line 460 so that the folded first transversal area contacts the second transversal area. After being folded, the liner 2 in the folded first transversal area comes into contact with the liner 2 in the second transversal are a.
[0080] Fig. 6 shows a flow chart of folding a fine or ultra-fine face mask according to the fifth preferred embodiment of the present invention. In this embodiment, the face mask 1 has exactly five longitudinal lines 510, 520, 530, 540, 550 extending parallel to the longitudinal direction of the face mask 1, and the face mask 1 is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area, a fourth longitudinal area, a fifth longitudinal area and a sixth longitudinal area having substantially the same width by the first longitudinal line 510, the second longitudinal line 520, the third longitudinal line 530, the fourth longitudinal line 540 and the fifth longitudinal line 550.
[0081] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Similar to the face mask 1 shown in FIG. 1, the liner 2 is also located above the tissue 3 in FIG. 6. This means that the tissue 3 rests against the countertop while the liner 2 faces away from the countertop.
[0082] In the second step, the first longitudinal area is folded inwardly along the first longitudinal line 510 so that the first longitudinal area is located above the second longitudinal area.
[0083] In the third step, the folded first longitudinal area is folded inwardly along the second longitudinal line 520 so that the first longitudinal area contacts the third longitudinal area.
[0084] In the fourth step, the sixth longitudinal area is folded inwardly along the fifth longitudinal line 550 so that the sixth longitudinal area is located above the fifth longitudinal area.
[0085] In the fifth step, the folded sixth longitudinal area is folded inwardly along the fourth longitudinal line 540 so that the sixth longitudinal area contacts the fourth longitudinal area.

After being folded, the liner 2 in the folded first transversal area comes into contact with the liner 2 in the second transversal are a.
[0088] Fig. 7 shows a flow chart of folding a fine or ultra-fine face mask according to the sixth preferred embodiment of the present invention. In this embodiment, the face mask 1 has exactly three longitudinal lines 610, 620, 630 extending parallel to the longitudinal direction of the face mask 1, and the face mask 1 is divided into a first longitudinal area, a second longitudinal area, a third longitudinal area and a fourth longitudinal area having substantially the same width by the first longitudinal line 610, the second longitudinal line 620 and the third longitudinal line 630.
[0089] In the first step, the mask 1 is placed flat on a countertop, and the tissue 3 and the liner 2 are overlapped and in contact with each other. Similar to the face mask 1 shown in FIG. 1, the liner 2 is also located above the tissue 3 in FIG. 7. This means that the tissue 3 rests against the countertop while the liner 2 faces away from the countertop.
[0090] In the second step, the first longitudinal area is folded inwardly along the first longitudinal line 610 so that the first longitudinal area is above the second longitudinal area.
[0091] In the third step, different from the third embodiment of FIG. 4, the folded first longitudinal area is further folded inwardly along the second longitudinal line 620 in the same direction as in the second step, so that the folded first longitudinal region is located above the third longitudinal region.
[0092] In the fourth step, the folded second longitudinal area is further folded along the third longitudinal line 630 in the same direction as the previous steps 2 and 3, so that the second longitudinal area is in contact with the fourth longitudinal area.
[0093] In the fifth step, the first transversal area is folded along the first transversal line 660 so that the folded first transversal area contacts the second transversal area. After being folded, the liner 2 in the folded first transversal area comes into contact with the liner 2 in the second transversal are a.
[0094] The folding method shown in the sixth embodiment of FIG. 7 is also applicable to a mask having four to five longitudinal lines. In this method, the face mask 1 is always folded in the same direction along each longitudinal line in sequence so that the width of the folded face mask 1 corresponds to the width of one longitudinal area.
[0095] In the embodiments of folding methods shown in FIGS. 2-7, each method begins by folding the left portion of the face mask. However, it is also possible to folding the right portion of the face mask first. That means, the face mask can be folded from left to right or from right to left.
[0096] FIG. 8 shows a top view of a face mask according to a seventh preferred embodiment of the present invention. The main difference between the mask shown in FIG. 8 and the mask shown in FIG. 1 lies in that the mask of FIG. 8 includes two dividing lines 5 on the two cheek portions of the mask respectively to better fit different facial features.
