Description

[Technical Field]

[0001] The present invention relates to a mask that covers at least a portion of a user's face. [Background technology]

[0002] Masks worn on the face are typically required to prevent viruses, bacteria, dust, and the like from entering the mouth, nose, etc. The mask in Patent Document 1 has sheets attached along the left and right edges inside the mask body. These sheets seal gaps formed between the mask and the areas of the face around the ears, preventing exhaled air from leaking or air from being inhaled through such gaps. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-30654 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even with the mask of Patent Document 1, the adhesion between the mask and the face is still poor, and the mask is not able to adequately prevent the entry of viruses, bacteria, dust, etc., so there is room for improvement.

[0005] The present invention aims to provide a mask that closely adheres to the face. [Means for solving the problem]

[0006] A mask according to a first aspect of the present invention includes a mask body having a first edge and a second edge opposite the first edge and covering at least a portion of a user's face, and a first cloth and a second cloth arranged inside the mask body and in contact with the face. The first cloth is arranged closer to the first edge than the second cloth, and the second cloth is arranged closer to the second edge than the first cloth. The first cloth and the second cloth partially overlap each other, and when the mask body is worn on the face, they are deployed so that the overlapping area is small.

[0007] A mask according to a second aspect of the present invention is the mask according to the first aspect, wherein the first edge is an upper edge and the second edge is a lower edge.

[0008] A mask according to a third aspect of the present invention is the mask according to the second aspect, wherein the second fabric has a lower portion, a left end portion, and a right end portion. The lower portion is fixed to one or more fixing points near the center of the mask body in the left-right direction, and is not fixed to the mask body between the one or more fixing points and the left end portion, and between the one or more fixing points and the right end portion.

[0009] A mask according to a fourth aspect of the present invention is a mask according to any one of the first to third aspects, wherein at least one of the first fabric and the second fabric is impregnated with a beauty ingredient.

[0010] A mask according to a fifth aspect of the present invention is a mask according to any one of the first to fourth aspects, wherein when the mask body is worn on the face and the first cloth and the second cloth are deployed, a gap is formed between the first cloth and the second cloth to accommodate at least one of the mouth and nose of the user. [Effects of the Invention]

[0011] According to the above viewpoint, the first cloth and the second cloth that come into contact with the face are arranged inside the mask body. The first cloth is arranged closer to the first edge of the mask body than the second cloth, and the second cloth is arranged closer to the second edge of the mask body that faces the first edge than the first cloth. The first cloth and the second cloth partially overlap, and when the mask body is worn on the face, they are deployed so that the overlapping area between the two is small. Therefore, when the mask body is worn on the face, the contact area between the first cloth and the second cloth and the face increases. This improves the fit between the mask and the face.

DETAILED DESCRIPTION OF THE INVENTION

[0013] A mask according to one embodiment of the present invention will be described below with reference to the drawings.

[0014] 1. First Embodiment 1 and 2 show the mask 1 according to this embodiment as viewed from the inside, and FIGS. 3 and 4 show the mask 1 as viewed from the outside. The mask 1 unfolds three-dimensionally when worn on the user's face. FIGS. 1 and 3 show the mask 1 before unfolding, and FIGS. 2 and 4 show the mask 1 after unfolding. FIG. 5 is a cross-sectional view taken along line VV in FIG. 1, and FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 2. In the following description, up and down, left and right, and front and back are defined as shown in FIGS. 1 to 6, based on a state in which a user is wearing the mask 1 while standing.

[0015] As shown in FIGS. 1 to 6 , the mask 1 includes a mask main body 30 and two cloths 10 and 20 that are overlapping the mask main body 30 inside the mask main body 30. Hereinafter, the cloths 10 and 20 will be distinguished from each other by referring to 10 as the first cloth and 20 as the second cloth. The mask main body 30 is a cloth that covers at least a portion of the face, and in this embodiment, it mainly covers the mouth and nose. When the mask 1 is worn on the face, the first cloth 10 and the second cloth 20 are sandwiched between the face and the mask main body 30 and come into contact with the face, thereby enhancing the fit between the mask 1 and the face. The mask 1 also has ear loops 40 connected to the mask main body 30. The ear loops 40 are hooked onto the left and right ears of the user when the mask 1 is worn on the face, thereby maintaining the mask main body 30, the first cloth 10, and the second cloth 20 covering the areas of the face around the mouth and nose.

[0016] The mask body 30 is a sheet-like member made of a breathable sheet material such as a nonwoven fabric or woven fabric. The sheet material here is preferably made of a nonwoven fabric formed by a spunbonding method, meltblown method, thermalbonding method, spunlace method, or the like. From the viewpoint of shape retention, a nonwoven fabric formed by a spunbonding method is particularly preferable. The fiber material constituting the sheet material here can be selected from synthetic fibers such as polypropylene, polyethylene, and polyester, or natural fibers such as paper, rayon, and cotton. The mask body 30 may have a single-layer structure consisting of a single sheet material, or a multi-layer structure consisting of two, three, or more stacked sheets. The mask body 30 can be made of, for example, an S layer (single layer of spunbond), an SS layer (two-layer structure of spunbond-spunbond), an SSS layer (three-layer structure of spunbond-spunbond-spunbond), or an SMS layer (three-layer structure of spunbond-meltblown-spunbond).

[0017] In this embodiment, the first fabric 10 and the second fabric 20 are impregnated with a medicinal agent, and the medicinal agent contains a cosmetic ingredient that has a cosmetic effect on the skin. Therefore, when the first fabric 10 and the second fabric 20 come into contact with the face during wearing of the mask 1, the medicinal agent containing the cosmetic ingredient is applied to the face. In this embodiment, the cosmetic ingredient refers to a moisturizing ingredient, and the medicinal agent includes not only the moisturizing ingredient but also preservatives and water. Examples of moisturizing ingredients include glycerin, collagen, hyaluronic acid, ceramide, and squalane, but from the perspective of exerting a moisturizing effect when impregnated into the fabrics 10 and 20, glycerin and hyaluronic acid are particularly preferred. When the mask 1 is intended for daytime use, the proportion of the cosmetic ingredient contained in the medicinal agent is preferably 5 to 30 weight percent. Examples of preservatives include iodopropynyl butylcarbamate, methyl parahydroxybenzoate, propyl parahydroxybenzoate, and phenoxyethanol, with iodopropynyl butylcarbamate being particularly preferred from the viewpoint of exhibiting resistance to mold. Note that the cosmetic ingredient may contain one or more elements selected from the group including whitening agents (vitamin C derivatives, hydroquinone, arbutin, etc.), astringents (citric acid, alum, ethanol, etc.), skin protectants, and skin nutrients, instead of or in addition to the moisturizing ingredients described above.

[0018] The first fabric 10 and the second fabric 20 are also sheet-like members, each made of a breathable sheet material such as a nonwoven fabric or a woven fabric. The sheet material here can also be made of a nonwoven fabric formed by a spunbonding method, meltblowing method, thermal bonding method, spunlace method, or the like. From the viewpoint of retaining the drug, it is particularly preferable to make it of a nonwoven fabric formed by a spunlace method. Furthermore, the fiber material making up the sheet material here can be selected from synthetic fibers such as polypropylene, polyethylene, and polyester, or natural fibers such as paper, rayon, and cotton. The first fabric 10 and the second fabric 20 can each have a single-layer structure made of a single sheet material, or a multi-layer structure made of two, three, or more stacked sheet materials.

[0019] The mask body 30 is configured to be able to be deployed three-dimensionally. More specifically, as shown in FIGS. 3 to 5, the mask body 30 has one or more pleats 31 extending in the left-right direction. As shown in FIGS. 5 and 6, when the mask body 30 is pulled in the vertical direction and the pleats 31 are deployed in the vertical direction, the mask body 30 extends in the vertical direction. At this time, mainly the central portion of the mask body 30 in the left-right direction extends in the vertical direction. This allows the mask body 30 to cover a wider area of ​​the face. As shown in FIG. 5, the pleats 31 are folded before deployment, and at this time, the mask body 30 is generally flat. On the other hand, as shown in FIG. 6, after the pleats 31 are deployed, the mask body 30 expands into a dome shape. In other words, the mask body 30 not only expands in the vertical direction, but also expands forward so that its central portion in the vertical direction protrudes, thereby expanding three-dimensionally. In FIG. 5, the mask 1 is depicted as being relatively three-dimensional in the front-to-back direction for ease of understanding, but in reality it is more planar.

[0020] The mask body 30 has an upper edge L1, a lower edge L2 opposite the upper edge L1, a left edge L3, and a right edge L4 opposite the left edge L3, and is generally rectangular in shape before being unfolded. As shown in FIG. 1 , the first cloth 10 and the second cloth 20 both extend in the left-right direction from the left edge L3 to the right edge L4 of the mask body 30. The first cloth 10 also extends in the up-down direction from the upper edge L1 to near the center line of the mask body 30 in the up-down direction. That is, the first cloth 10 covers roughly the upper half of the mask body 30 and is generally rectangular in shape. Meanwhile, the second cloth 20 extends in the up-down direction from slightly above the center line of the mask body 30 in the up-down direction to slightly above the lower edge L2. The second cloth 20 also has a generally rectangular shape.

[0021] As described above, the first cloth 10 is disposed closer to the upper edge L1 than the second cloth 20, and the second cloth 20 is disposed closer to the lower edge L2 than the first cloth 10. The first cloth 10 and the second cloth 20 partially overlap in the vertical direction, with the second cloth 20 being disposed further back (closer to the face and farther from the mask body 30). Note that in FIG. 1, the lower edge of the first cloth 10, which is not visible due to the presence of the second cloth 20, is shown by a dashed line for reference.

[0022] The top, left, and right sides that form the outer periphery of the first cloth 10 overlap with the top, left, and right sides L1, L3, and L4 that form the outer periphery of the mask body 30, respectively. The first cloth 10 is fixed to the mask body 30 along the entire width of its top, left, and right sides. Note that line C1 shown in FIGS. 1 to 4 indicates the points where the cloths 10 and 20 are fixed to the mask body 30. On the other hand, the first cloth 10 is not fixed to the mask body 30 along its bottom side. Therefore, the first cloth 10, together with the mask body 30 that faces it, is configured in the shape of a bag with an open bottom.

[0023] The left and right sides that form the outer periphery of the second cloth 20 overlap with the left and right sides L3 and L4 that form the outer periphery of the mask body 30, respectively. The second cloth 20 is fixed to the mask body 30 along the entire width of its left and right sides (see line C1 in FIGS. 1 and 2). Meanwhile, the second cloth 20 is not fixed to the mask body 30 along its upper side, and is fixed to one or more fixing points P1 of the mask body 30 along its lower side.

[0024] More specifically, the second fabric 20 has a lower portion 20D, a left end portion 20L, and a right end portion 20R extending along its bottom edge, left edge, and right edge, respectively. In this embodiment, the lower portion 20D is fixed to the mask body 30 at four fixing points P1. These fixing points P1 are located two on each side of the center of the mask body 30 in the left-right direction. The lower portion 20D is not fixed between the two inner fixing points P1, P1, between the leftmost fixing point P1 and the left end portion 20L, and between the rightmost fixing point P1 and the right end portion 20R.

[0025] The method for fixing the cloths 10 and 20 to the mask body 30 can be selected as appropriate. For example, methods such as heat fusion (including ultrasonic fusion) or sewing can be used. In this embodiment, heat fusion is performed in a dashed line along line C1 shown in Figures 1 to 4.

[0026] As described above, the mask body 30 unfolds three-dimensionally when worn on the face. At this time, as shown in Figures 2 and 6, the first cloth 10 and the second cloth 20 also unfold three-dimensionally, with the lower part of the first cloth 10 and the upper part of the second cloth 20 protruding slightly forward. This allows the cloths 10 and 20 to closely contact parts of the face that have a three-dimensional structure, such as the tip of the nose and around the mouth. The cloths 10 and 20 can also closely contact parts of the face that are relatively flat, such as the cheeks and the areas surrounding the left and right sides of the mouth and below.

[0027] When the mask body 30 is unfolded, the first fabric 10 and the second fabric 20 are unfolded so that the overlapping area between them is reduced. Therefore, when the mask body 30 is worn on the face, the contact area between the first fabric 10 and the second fabric 20 and the face increases, improving the adhesion between the mask 1 and the face. Therefore, the mask 1 can efficiently prevent viruses, bacteria, dust, etc. from entering the mouth, nose, etc. Furthermore, in this embodiment, such high adhesion allows the beauty ingredients impregnated in the fabrics 10 and 20 to be efficiently applied to the face.

[0028] As described above, the first cloth 10 is not fixed to the mask body 30 along its lower edge, and the second cloth 20 is not fixed to the mask body 30 along its upper edge. Therefore, the lower part of the first cloth 10 and the upper part of the second cloth 20 do not follow the bulge of the mask body 30 and are not pulled excessively forward. Similarly, the lower part of the second cloth 20 is not fixed to the mask body 30 except at the fixed point P1. Therefore, the lower part of the second cloth 20 does not follow the bulge of the mask body 30 and are not pulled excessively forward except near the center in the left-right direction where the fixed point P1 is located. Therefore, the first cloth 10 and the second cloth 20 can fit snugly to the face.

[0029] Furthermore, when the mask body 30 is unfolded, a gap S1 is formed between the first cloth 10 and the second cloth 20, mainly in the center portion in the left-right direction of the mask body 30 (see FIGS. 2 and 6). This gap S1 can mainly accommodate the user's mouth and nose. Therefore, when a user wears the mask 1, the first cloth 10 and the second cloth 20 are in close contact with the user's face, but the user can breathe easily.

[0030] Before the mask 1 is unfolded, the vertical length of the first fabric 10 is R1, the vertical length of the second fabric 20 is R2, and the vertical length of the overlapping portion of the first fabric 10 and the second fabric 20 is R3. From the viewpoint of ensuring a sufficient contact area between the fabrics 10 and 20 and the face, it is preferable that R3 / R1≧0.1, more preferably R3 / R1≧0.2, and even more preferably R3 / R1≧0.3. From the same viewpoint, it is preferable that R3 / R2≧0.1, more preferably R3 / R2≧0.2, and even more preferably R3 / R2≧0.3. From the same viewpoint, it is preferable that R3≧0.5 cm, more preferably R3≧1.0 cm, and even more preferably R3≧1.5 cm.

[0031] From the viewpoint of ensuring a sufficient gap S1 to accommodate the nose and mouth, it is preferable that R3 / R1≦0.8, more preferably that R3 / R1≦0.7, and even more preferably that R3 / R1≦0.6. From the same viewpoint, it is preferable that R3 / R2≦0.8, more preferably that R3 / R2≦0.7, and even more preferably that R3 / R2≦0.6. From the same viewpoint, it is preferable that R3≦4.0 cm, more preferably that R3≦3.5 cm, even more preferably that R3≦3.0 cm, and even more preferably that R3≦2.5 cm.

[0032] The ear loop portion 40 has a pair of left and right string members 41 and 42. Both ends of the left string member 41 are fixed to the upper and lower ends of the left end of the mask body 30, respectively, so that the string member 41 forms a closed loop together with the left end of the mask body 30. Similarly, both ends of the right string member 42 are fixed to the upper and lower ends of the right end of the mask body 30, respectively, so that the string member 42 forms a closed loop together with the right end of the mask body 30. This allows the string members 41 and 42 to be hooked onto the left and right ears, respectively. The method for fixing the string members 41 and 42 to the mask body 30 is not particularly limited, but methods such as heat fusion (including ultrasonic fusion) and sewing can be used.

[0033] From the viewpoint of enabling the string members 41 and 42 to be securely hooked onto the ears regardless of the size of the user's face, it is preferable that the string members 41 and 42 have stretchability along their longitudinal direction. The material constituting the string members 41 and 42 is not particularly limited, but polyester, for example, can be used.

[0034] A linear nose piece 50 is fixed to the mask body 30 along its upper edge L1. The nose piece 50 is made of a material that is easily bendable and plastically deformable, such as plastic resin or metal. When a user wears the mask 1, the nose piece 50 is folded to fit the shape of the nose, thereby reducing the gap between the mask 1 and the nose. As shown in FIGS. 5 and 6, in this embodiment, the mask body 30 is folded forward along the upper edge L1 and the lower edge L2, and is double-layered at the top and bottom. The nose piece 50 is embedded between the double-layered portions at the top of the mask body 30. Therefore, the nose piece 50 is not actually visible in FIGS. 1 to 4, but its position is shown by a dashed line for reference. In this embodiment, the nose piece 50 is heat-sealed (or may be sewn) to the mask 1 so as to surround the nose piece 50 so that the nose piece 50 does not fall off the mask body 30 (see line C1 in FIGS. 1 to 4).

[0035] <2. Modifications> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0036] <2-1> In the above embodiment, both the first fabric 10 and the second fabric 20 are impregnated with cosmetic ingredients, but cosmetic ingredients may be impregnated into only one of them. Furthermore, cosmetic ingredients may not be impregnated into either the first fabric 10 or the second fabric 20. In this case, the cosmetic effects of the cosmetic ingredients are not obtained, but the mask 1 is still useful in that it adheres closely to the face and can efficiently prevent viruses, bacteria, dust, and the like from entering the mouth, nose, etc.

[0037] <2-2> In the above embodiment, the first cloth 10 and the second cloth 20 are arranged side by side with some overlapping in the vertical direction, but for example, they may be arranged side by side with some overlapping in the horizontal direction, as shown in Fig. 7. Note that in this case as well, it is preferable that a gap S1 is formed between the first cloth 10 and the second cloth 20 when the mask 1 is unfolded.

[0038] <2-3> The gap S1 formed between the first fabric 10 and the second fabric 20 when the mask 1 is deployed may be formed to accommodate only the mouth or only the nose of the user.

[0039] <2-4> The number of pleats 31 is not particularly limited, and may be one, or the pleats 31 may be omitted from the mask body 30. Even when the pleats 31 are omitted, the mask body 30 can be unfolded three-dimensionally by, for example, leaving the mask body 30 loose before unfolding, and then pushing the center of the mask body 30 forward when unfolding.
