Description

[Technical Field]

[0001] The present invention relates to a mask and a method for manufacturing a mask. [Background technology]

[0002] A typical mask configuration includes a mask body that at least partially covers the wearer's face and a pair of ear loops that are each connected to the mask body. While most mask ear loops are string-like, sheet-like ear loops are also known. For example, Patent Document 1 describes a mask configuration in which ear loops formed as a single sheet are connected to both end regions of the mask body at joints of the ear loops.

[0003] Furthermore, there are known masks in which a specific chemical agent is used to provide the mask body with some additional function. For example, Patent Document 2 describes a moisturizing mask in which a liquid impregnation means including a liquid-impregnated portion impregnated with a liquid such as a cosmetic is provided on the inner surface of the breathable fabric portion of the mask body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5762803 [Patent Document 2] Patent No. 5734530 Summary of the Invention [Problem to be solved by the invention]

[0005] The moisturizing mask described in Patent Document 2 has the advantage that the moisturizing effect lasts for a long period of time because the liquid is evaporated little by little from the liquid-impregnated portion. However, the configuration of the liquid-impregnating means, etc. can be complicated, which makes manufacturing time-consuming.

[0006] Alternatively, it may be possible to apply the medication directly to the mask body. However, the sheet-like ear loops described in Patent Document 1 are bonded to the mask body in a predetermined area. Therefore, depending on the manufacturing procedure, the medication may be placed in a predetermined area between the mask body and the ear loops. This may reduce the bonding strength between the mask body and the ear loops.

[0007] In view of the above, one aspect of the present invention aims to provide a mask with sheet-like ear loops that uses chemicals to give the mask additional functionality and that has sufficient bonding strength between the mask body and the ear loops. [Means for solving the problem]

[0008] A first aspect of the present invention is a mask comprising a main body and a pair of sheet-like ear hooks, the pair of sheet-like ear hooks being joined at joint areas to each lateral end of the main body on the face-facing or non-face-facing side, the main body having a drug application surface on at least the face-facing side on which a plurality of discontinuous drug application areas are formed, the drug application surface facing the sheet-like ear hooks in at least part of the joint area, and the area ratio of the drug application areas in the joint area of ​​the drug application surface being 70% or less.

[0009] According to the first aspect, the ear hooks are formed in a sheet-like shape, allowing the ear hooks to make surface contact with the wearer's skin behind or behind the ear when worn. This prevents excessive pressure from being applied to the skin, reducing strain on the skin and providing a comfortable fit. Furthermore, because the sheet-like ear hooks are joined to the main body at the joining area and connected across a predetermined area in the thickness direction, the ear hooks are less likely to come off the main body than string-like ear hooks that are connected to the main body over a small area.

[0010] Furthermore, since the main body has a drug application surface on which the drug application portion is formed, the desired effect of the drug can be imparted to the face-facing surface of the main body. Therefore, the mask can be given additional functions as desired depending on the drug selected. Furthermore, since the drug application surface is provided at least on the face-facing side, the drug can easily come into contact with the face, particularly in the case of drugs that exert their effects through direct contact with the skin, allowing the drug's effects to be more pronounced.

[0011] Furthermore, in this embodiment, the drug-application surface of the main body and the ear hooks face each other in at least a portion of the bonding area. In this case, the drug-application area is disposed between the main body and the ear hooks, and depending on the type and amount of drug, or the bonding method between the main body and the ear hooks, the bonding strength between the main body and the ear hooks may be reduced. In contrast, in this embodiment, the area ratio of the drug-application area in the bonding area of ​​the drug-application surface is 70% or less, thereby preventing a decrease in the bonding strength between the main body and the ear hooks. In other words, the bonding strength between the main body and the ear hooks can be maintained while the drug provides additional functionality to the mask.

[0012] In a second aspect of the present invention, the area ratio of the drug-applied portion to the entire drug-applied surface is 10 to 80%.

[0013] According to the second aspect, the area ratio of the drug-applied portion to the entire drug-applied surface is within a predetermined range, thereby enhancing the effect of the drug and reducing the possibility that the area ratio of the drug to the drug-applied surface will become too large, causing the drug to become sticky or impairing the original characteristics (filtering performance, etc.) of the main body material.

[0014] In a third aspect of the present invention, the plurality of drug application portions are arranged spaced apart from one another in the vertical and horizontal directions.

[0015] According to the third aspect, the drug application portions can be arranged in a two-dimensionally dispersed manner, which reduces the possibility of impairing the original characteristics of the main body material while maintaining the effect of the drug, and also reduces the cost of the drug because the amount of drug can be reduced.

[0016] In a fourth aspect of the present invention, the pair of sheet-like ear hook portions are joined to the non-face-facing side of the main body, and at least one vertical end of the main body is folded back to the non-face-facing side of the main body, thereby exposing the drug application surface.

[0017] According to the fourth aspect, the ear loops are attached to the non-face-facing side of the mask body, reducing the likelihood that the user will touch the face-facing side of the mask body when unfolding the ear loops to the left and right (horizontally) at the start of use, allowing for hygienic wearing. Furthermore, in this aspect, the upper and / or lower longitudinal ends of the mask body are folded over, preventing the edges of the sheet material constituting the mask body from touching the face or hands, improving comfort. Furthermore, because the medicinal agent application surface is located not only on the face-facing side but also on the non-face-facing side, the medicinal agent can exert its effect on the user's fingers when the user touches the face-facing side of the mask body with their fingers.

[0018] In this embodiment, since the drug application surface is exposed on the side not facing the face, a drug can be placed between the main body and the ear hook portion in the joint area between them. Even with this configuration, the area ratio of the drug application portion in the joint area of ​​the drug application surface is equal to or less than a predetermined value, so that a decrease in the joint strength between the main body and the ear hook portion in the joint area is prevented.

[0019] In a fifth aspect of the present invention, the main body has a plurality of stacked sheets, and at least the face-facing surface of the face-facing sheet that is positioned furthest from the face among the plurality of sheets is the drug application surface, and at least one longitudinal end of the face-facing sheet is folded back to the non-face-facing side of the main body.

[0020] According to the fifth aspect, the mask body has a multilayer structure, i.e., it has a plurality of stacked sheets. Therefore, each sheet can have a different function depending on the arrangement of the sheets, providing a mask body configuration suited to the mask's intended use. Furthermore, the continuous sheet positioned closest to the face among the plurality of sheets, with the face-facing surface being the drug-application surface, is folded back at at least one longitudinal end. Therefore, at that at least one longitudinal end, the drug-application surface extends from the face-facing side to the edge of the end and further to the non-face-facing side. Therefore, if the drug has a texture or tactile effect, a pleasant sensation can be imparted to the face or fingers when the upper and / or lower edges of the mask body touch the face or fingers.

[0021] In a sixth aspect of the present invention, the distance between one of the medicinal application portions and another medicinal application portion adjacent to the one medicinal application portion is larger than the circle-equivalent diameter of one of the medicinal application portions.

[0022] According to the sixth aspect, the drug-applied portions are formed on the drug-applied surface with wide intervals between them, which prevents the drug-applied portions from becoming too dense in the bonded region, thereby improving the aforementioned effect of preventing a decrease in bond strength in the bonded region.

[0023] In a seventh aspect of the present invention, the agent is an agent that exerts one or more of the functions of moisturizing, smoothing, and adding fragrance.

[0024] According to the seventh aspect, by using a drug that exerts a predetermined action, an additional predetermined function is imparted to the mask in addition to its original function.

[0025] In an eighth aspect of the present invention, a drug application surface having a plurality of discontinuous drug application areas is formed on at least the face-facing side of the main body, and then a pair of sheet-like ear hooks are joined at a joining area to each lateral end of the face-facing or non-face-facing side of the main body, so that the drug application surface faces the sheet-like ear hooks in at least a part of the joining area, and the area ratio of the drug application areas in the joining area is 70% or less.

[0026] According to the eighth aspect, it is possible to provide a method for manufacturing a mask that has the same effects as the first aspect. [Effects of the Invention]

[0027] According to one aspect of the present invention, in a mask equipped with sheet-like ear loops, additional functions are given to the mask using a chemical, and a configuration can be provided in which the bonding strength between the mask body and the ear loops is sufficient.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding components will be denoted by the same reference numerals and the description thereof will be omitted.

[0030] <Basic mask configuration> One aspect of the present invention is a mask that can cover the wearer's face, more specifically at least the wearer's nose and mouth. This mask can have the function of preventing foreign objects from reaching the face and preventing droplets emitted by the wearer from spreading, and is also called a sanitary mask or surgical mask. The mask may be disposable or reusable after washing.

[0031] Fig. 1 shows a plan view of the mask 1. Fig. 1 shows the mask 1 as seen from the non-face-facing side (outside), i.e., the side that does not face the face when worn and is exposed to the outside. Fig. 2 shows a plan view of the mask as seen from the face-facing side (inside), i.e., the side that faces the face.

[0032] As shown in Figure 1, the mask 1 of this embodiment includes a mask main body (hereinafter also referred to simply as "main body") 10 that is placed in front of the wearer's face when worn and that can cover mainly the wearer's nose and mouth, and a pair of sheet-like ear loops 20a, 20a each joined to the mask main body 10. The mask 1 and mask main body 10 have an up-down direction (vertical direction) D1 that corresponds to the up-down direction of the wearer's face when worn, and a left-right direction (horizontal direction) D2 that corresponds to the left-right direction of the wearer's face when worn. The vertical direction D1 and the horizontal direction D2 are perpendicular to each other.

[0033] (Mask body) The mask body 10 shown in FIGS. 1 and 2 has a rectangular shape in plan view with long sides in the horizontal direction D2, but the shape of the mask body 10 in plan view is not limited to that shown. Also, as shown in FIGS. 1 and 2, the mask body 10 has a pleated structure 15 formed by a plurality of pleats arranged in the vertical direction D1. The pleats of the pleated structure 15 are formed by folding the sheet constituting the mask body 10 along fold lines along the horizontal direction D2. Then, with the plurality of pleats formed, both ends of the mask body 10 in the horizontal direction D2 are fixed by heat sealing, ultrasonic sealing, adhesive, or the like. Therefore, when the mask 1 is used, the pleats of the pleated structure 15 near the center of the mask 1 in the horizontal direction D2 can be expanded in the vertical direction D1. As a result, the center of the mask body 10 in the horizontal direction D2 curves so as to protrude toward the side of the mask 1 that does not face the face in both the vertical direction D1 and the horizontal direction D2, and can be deformed into a shape that fits the three-dimensional shape of the face. The specific configuration of the pleat structure 15 is not particularly limited, and may be a known configuration formed on the mask body. However, as shown in Figures 1 and 2, a pleat structure in which box pleats are formed in the center of the vertical direction D1 is preferable because this makes it easier to protrude the center of the vertical direction D1 of the mask body 10 away from the face when worn.

[0034] The mask body 10 may have a multilayer structure formed by stacking multiple sheets. FIG. 3 shows a cross-sectional view of the end region of the mask 1 where the ear loops 20a, 20a are joined to the mask body 10 (a cross-sectional view taken along line II in FIG. 1; the pleat structure is omitted). As shown in FIG. 3, the mask body 10 has a three-layer structure in which, from the face-facing side, an inner sheet (face-facing sheet) 11, an intermediate sheet 12, and an outer sheet 13 are stacked in this order. Each sheet constituting the mask body 10 preferably includes a fiber-containing layer such as a nonwoven fabric, woven fabric, or knitted fabric, and more preferably includes a nonwoven fabric. Examples of nonwoven fabrics include spunbond nonwoven fabrics, spunlace nonwoven fabrics, meltblown nonwoven fabrics, air-through nonwoven fabrics, and point-bond nonwoven fabrics. The intermediate sheet 12 is preferably a sheet with enhanced foreign matter (dust, pollen, bacteria, viruses, etc.) capturing function, and therefore, a meltblown nonwoven fabric that can contain fine fibers is preferably used. The fibers constituting the nonwoven fabric are preferably resin fibers, and examples of the resins of the resin fibers include polyethylene, polypropylene, polyethylene terephthalate, nylon, etc. The basis weight of the inner sheet (face-facing sheet) 11 and the outer sheet 13 is 10 to 50 g / m 2 The basis weight of the intermediate sheet having high foreign matter collection properties may be 10 to 100 g / m 2 It is preferable that the density is 10 to 50 g / m 2 and preferably 15 to 50 g / m 2 It is more preferable that:

[0035] In addition, the mask body 10 of this embodiment may be folded back at least on either the upper or lower side. The upper and / or lower edges of the mask body 10 may be cut edges and may be sharp, but by folding back as described above, the sharp edges are less likely to come into contact with the face or hands, improving the wearing comfort.

[0036] In the example shown in FIG. 3 , the mask body 10 is folded back at the upper and lower sides. More specifically, the inner sheet (face-facing sheet) 11 has a length in the longitudinal direction D1 greater than that of the intermediate sheet 12 and the outer sheet 13. That is, the inner sheet (face-facing sheet) 11 protrudes from the intermediate sheet 12 and the outer sheet 13 at its upper and lower ends. The protruding portion of the upper side of the inner sheet (face-facing sheet) 11 is folded back to the non-face-facing side so as to cover the upper edges of the intermediate sheet 12 and the outer sheet 13, forming an upper folded-back portion 11U. The protruding portion of the lower side of the inner sheet (face-facing sheet) 11 is folded back to the non-face-facing side so as to cover the lower edges of the intermediate sheet 12 and the outer sheet 13, forming a lower folded-back portion 11L. When only the inner sheet 11 is folded back at least at the upper and lower sides in this manner, the thickness of the mask body 10 is not excessively increased at the folded-back portion, thereby improving the wearing comfort as described above.

[0037] Furthermore, in the illustrated example, the inner sheet (face-facing sheet) 11 is folded over at the top and bottom, and is joined and fixed at the top and bottom joints 12U and 12L so that this state is maintained. Both the top joint 12U and the bottom joint 12L can be formed by heat sealing, ultrasonic sealing, adhesive, etc. In the example shown in Fig. 1, the top joint 12U and the bottom joint 12L are each formed in an intermittent, dot-like pattern.

[0038] As shown in FIG. 1, a shape-retaining member (also referred to as a nose fit) 30 extending in the lateral direction D2 may be disposed within the mask body 10. The shape-retaining member 30 is preferably disposed on the surface of the outer sheet 13 before folding back the upper folded portion 11U, and disposed between the upper folded portion 11U and the outer sheet 13. The shape-retaining member 30 may be a flat, band-shaped metal or resin member that is flexible and has shape-retaining properties. In other words, it can be easily deformed by the user's hands and can maintain the deformed state. By deforming this shape-retaining member 30 to conform to the shape of the nose area, the upper part of the mask body 10 can be tightly fitted to the face (nose), reducing any gaps.

[0039] The mask body 10 may have a mark 18 formed by embossing, printing, sewing, or the like to distinguish between the outer and inner surfaces of the mask body 10. The form of the mark 18 is not limited as long as it can be visually recognized by the user. The mark 18 may be a letter, a number, a symbol, a figure, a logo, or the like, as shown in FIG. 1, etc.

[0040] (Ear hook) Each of the pair of ear loops 20a, 20a has a continuous ring shape, and more specifically, may be circular or rectangular. When worn, the ear loops 20a can be placed around the wearer's ears so that the wearer's ears fit inside the loops, i.e., through the central openings 29 of the ear loops 20a. This allows the mask body 10 to be held in the worn position.

[0041] As shown in Figures 1 and 2, the pair of ear loops 20a, 20a are formed in a sheet shape, rather than a string or thread shape. That is, each of the pair of ear loops 20a, 20a forms a band-like ring with a certain width in a plan view. Therefore, when the ear loops 20a are placed over the ears while wearing the mask, they come into surface contact with the back of the ear or the back of the earlobe, thereby reducing strain on the ears. This reduces discomfort even when worn for long periods of time.

[0042] In the embodiment shown in FIGS. 1 and 2, the pair of ear loops 20a, 20a are formed as a single sheet detachably joined to each other at the center in the horizontal direction D2, i.e., as the ear loop sheet 20. Here, a single sheet refers to a form consisting of a single continuous sheet. This single sheet may be a single layer or a laminate consisting of multiple layers. Forming the pair of ear loops 20a, 20a in a single sheet allows for simultaneous positioning of the ear loops 20a, 20a during manufacturing, making mask manufacturing easier. Note that in this embodiment, the pair of ear loops 20a, 20a do not necessarily have to be joined together.

[0043] When a pair of ear hooks 20a, 20a together form a single ear hook sheet 20, the ear hook sheet 20 may be configured so that the pair of separate ear hooks 20a, 20a can be formed by tearing at a predetermined position. In the embodiment shown in FIG. 1, the pair of ear hooks 20a, 20a are connected at a connecting portion 28. While the connecting portion 28 may be formed in any manner, it is preferable that the connecting portion 28 be connectable by the user's normal pulling force. For example, as shown in FIG. 1, the connecting portion 28 may be formed as a perforation. Alternatively, the connecting portion 28 may be formed by reducing the thickness of the sheet or by other means to weaken or make the boundary between the pair of ear hooks 20a, 20a more susceptible to stress. The connecting portion 28 may also be configured so that the user can cut it using a tool such as scissors.

[0044] The ear loops 20a, 20a may be stretchable at least in the lateral direction D2, preferably with greater stretchability than the mask body 10. The ear loops 20a, 20a may have any suitable stretchable configuration, but the ear loops 20a, 20a (or ear loop sheet 20) are preferably constructed from a stretchable material and low-stretch or non-stretch sheet-like surface materials disposed on both sides of the stretchable material. More specifically, the stretchable ear loops 20a, 20a can be formed by applying a tensile force to the stretchable material, laminating low-stretch or non-stretch sheets (surface materials) on each side of the stretchable material, intermittently fixing the stretchable film and surface materials, and then releasing the tensile force to release the stretchable material.

[0045] The stretchable member may be an elastic stretchable member such as a stretchable film or a plurality of rubber threads. Of these, stretchable films are preferred because they are less complicated to arrange during production than rubber threads and provide high stretchability. Examples of materials for stretchable films include polyolefins such as polyethylene and polypropylene, and polyurethane. The stretchability of the stretchable film is preferably such that the maximum elongation ratio is 3.5 to 4.0 times the natural length when measured using a tensile tester. The stretchable film may also have a moisture-permeable function.

[0046] The sheets (surface materials) placed on both sides of the stretchable film may be the same or different. Furthermore, the surface material is preferably a fiber structure, more specifically, a nonwoven fabric, woven fabric, knitted fabric, or the like. Among these, nonwoven fabric is preferred because it has a good feel and breathability, contributing to improved wearing comfort. Examples of nonwoven fabric include air-through nonwoven fabric, spunbond nonwoven fabric, spunlace nonwoven fabric, needle-punched nonwoven fabric, and chemical-bond nonwoven fabric. Among these, a spunbond nonwoven fabric that is non-fuzzing and has high strength, or a soft air-through nonwoven fabric, or the like, can be appropriately selected. Furthermore, the fibers contained in the nonwoven fabric are preferably resin fibers, and examples of the resin type of the resin fiber include polyethylene, polypropylene, polyethylene terephthalate, and nylon. When the surface material is a nonwoven fabric, the basis weight of the nonwoven fabric is 5 to 50 g / m. 2 and in particular 8 to 25 g / m 2 is preferred.

[0047] In manufacturing the ear hooks 20a, 20a (ear hook sheet 20), the intermittent fixation of the stretchable film and surface material after lamination can be achieved using a fusing method such as ultrasonic sealing or heat sealing, or by using adhesives. Ultrasonic sealing is preferred because it allows for more reliable fixation, allows for small-area fusion, and improves the breathability of the ear hooks 20a (ear hook sheet 20). By intermittently fixing the stretchable film and surface material, when the stretchable film is released, the portions of the surface material not fixed to the stretchable film rise in a direction away from the stretchable film, resulting in the formation of multiple pleats on the surfaces (both sides) of the ear hooks 20a, 20a. More specifically, multiple pleats extending perpendicular to the stretch direction of the stretchable film can be formed in the stretch direction of the stretchable film. Due to the numerous folds on the surface of the ear hook portion 20a, when the surface of the ear hook portion 20a comes into contact with the skin, the material of the ear hook portion 20a does not come into contact with the entire surface of the skin, but a space is formed between the ear hook portion 20a and the skin, thereby reducing the feeling of the ear hook portion sticking to the skin and improving the wearing comfort.

[0048] It should be noted that the stretchable ear hook portions 20a, 20a may be made of a stretchable nonwoven fabric or the like instead of a stretchable film.

[0049] The weight of the entire ear hook portion 20a (ear hook portion sheet 20) is 20 to 150 g / m 2 The thickness of the ear hook portion 20a may be 100 to 3,000 μm.

[0050] (Connection between the mask body and ear loops) The pair of ear loops 20a, 20a are joined over a predetermined area to both sides of the mask body 10, i.e., both ends in the horizontal direction D2. A base 21, which is the ring-shaped portion of the ear loop 20a that extends in the vertical direction D1 on the outer side of the horizontal direction D2, is joined to an end region of the mask body 10 in the horizontal direction D2. If the ear loop 20a is rectangular, the base 21 corresponds to one of the four sides of the rectangle that extends in the vertical direction D1 on the outer side of the horizontal direction D2. In the example shown in FIG. 1, the inner contour of the base 21 is linear in the central region in the vertical direction D1, and the width of the base 21 (length in the horizontal direction D2) is also constant in the central region in the vertical direction D1. However, for example, the inner contour of the base 21 does not necessarily have to be linear in the central region in the vertical direction D1.

[0051] The bonding area 50 is the area where the mask body 10 and the ear loops 20a are bonded. Because the mask body 10 and the ear loops 20a (ear loop sheet 20) can be bonded over a certain area, the bond between the ear loops 20a and the mask body 10 can be maintained more stably than with string-like ear loops that are connected to the mask body over a small area. In other words, even if an excessively large force is applied, the ear loops 20a are less likely to come off the mask body 10. The bonding method is not particularly limited, and may be a method involving fusion, such as heat sealing or ultrasonic sealing, or an adhesive. However, embossing, which involves fusion, such as heat sealing, is preferred because it ensures a more secure bond between the mask body 10 and the ear loops 20a.

[0052] In the example shown in FIG. 1, the joining region 50 is formed so that its width w in the horizontal direction D2 is constant. The width w of the joining region 50 is preferably 3 to 15 mm. Furthermore, when the process for forming the joining region 50 is embossing involving fusion such as heat sealing, the region to which the fusion process is performed (the fusion-treated region) may be different from the joining region 50. That is, depending on the shape of the base 21 of the ear hook 20a, the joining region 50 may be included in the fusion-treated region. In the example shown in FIG. 1, the fusion-treated region and the joining region 50 are the same, and are rectangular regions extending in the vertical direction D1 with the width w described above. Furthermore, the width w of the joining region 50 may be smaller than the minimum width of the base 21 of the ear hook 20a. In this case, there will be regions of the base 21 of the ear hook 20a that are not joined to the mask body 10. If there is an area inside the lateral direction D2 of the base 21 that is not joined to the mask body 10, that area will open outward in the lateral direction D2 when the ear loops 20a, 20a are deployed during use.

[0053] In the joint region 50, the mask body 10 and the ear loops 20a may be joined throughout the entire joint region 50, but as shown in Figure 1, when viewed microscopically, there may be small joint areas 51, 51, ... where the mask body 10 and the ear loops 20a are joined, and non-jointed areas between the small joint areas 51, 51, .... By forming the small joint areas 51, 51, ... as separate points, it is possible to prevent the joint region 50 from becoming excessively rigid, which would impair the feel on the skin or in the hand when in use.

[0054] The ear loops 20a, 20a may be attached to either the non-face-facing side or the face-facing side of the mask body 10. However, by attaching the ear loops 20a, 20a to the non-face-facing side of the mask body 10 as shown in Figures 1 to 3, the possibility of the user touching the face-facing side of the mask body 10 can be reduced or eliminated when the ear loops 20a, 20a are separated and deployed outward in the lateral direction D2 at the start of use of the mask 1 (described in detail later). A method of using the mask 1, including the operation of separating and deploying the ear loops 20a, 20a, will be described in more detail below.

[0055] <How to use the mask> When starting to use the mask 1 according to this embodiment, the user can open the portions of the ear loops 20a, 20a that are not joined to the mask body 10 at the joining regions 50, 50 to the side (in the lateral direction D2) before putting on the mask 1. As described above, if the ear loops 20a, 20a are joined to each other at the joining portions 28, the joining can be released to separate the ear loops 20a, 20a from each other.

[0056] Figure 4 shows a plan view of the ear loops 20a, 20a of the mask 1 in Figure 1 after they have been unfolded. After the ear loops 20a, 20a are unfolded outward in the lateral direction D2, the ear loops 20a are turned inside out, exposing the surface of the ear loops 20a that faced the mask body 10. Almost the entire outer surface of the mask body 10 is also exposed.

[0057] 1 to 3, the ear loops 20a, 20a are joined to the side (outside) of the mask body 10 that does not face. Therefore, as described above, when the ear loops 20a, 20a are separated from each other and opened outward in the lateral direction D2, the possibility that the user will touch the face-facing side of the mask body 10 can be reduced or eliminated, which is preferable from a hygienic standpoint.

[0058] The mask 1 according to this embodiment can be used, for example, as follows: Before use (before deployment), the mask 1 is placed with the non-face-facing side (outside) of the mask body 10 facing up. The user then grasps the ear loops 20a, 20a with their hands and opens them outward in the lateral direction D2. Then, while still grasping the pair of ear loops 20a, 20a, the mask 1 is moved toward the face of another person (the wearer). After placing the mask body 10 in a desired position on the other person's face, the user can place the ear loops 20a, 20a over the other person's ears without changing the way the mask is held. Therefore, the mask 1 according to this embodiment is suitable for use when having someone who has difficulty putting a mask on themselves, such as a child or a sick person, put the mask on. Of course, when the user is the wearer, he or she can hold one or both of the pair of ear loops 20a, 20a and move the mask 1 to his or her face, and while holding the face-facing side of the mask body 10 facing the face with one hand, he or she can hang the ear loops 20a, 20a one by one over the ears with the other hand.

[0059] The ear loops 20a may have gripping portions 25 that the user can grip when separating the ear loops 20a and opening them outward in the lateral direction D2 (FIGS. 1, 2, and 4). The gripping portions 25 preferably protrude from the edge of the mask body 10 in a plan view, preferably from the lower end of the mask 1 (or the lower end of the mask body 10). In this case, the user can grip the gripping portions 25 with both hands without touching or barely touching the mask body 10 itself, i.e., either the face-facing or non-face-facing side of the mask body 10. This allows the user to separate and unfold the pair of ear loops 20a without touching or barely touching the mask body 10. This allows the user to put the mask 1 on themselves or on others in a hygienic state even in situations where they are unable to adequately maintain hand hygiene.

[0060] The above-mentioned knobs 25, 25 can also be used to adjust the position and tension of the ear hooking portions 20a, 20a by pulling the ear hooking portions 20a, 20a when or after the ear hooking portions 20a, 20a are hooked on the wearer's ears.

[0061] Furthermore, because the ear loops 20a, 20a are each attached to the non-face-facing side of the mask body 10, while the mask 1 is being worn, i.e., when the ear loops 20a, 20a are open to the sides and hanging over the ears, the ear loops 20a, 20a can easily press both sides of the mask body 10 toward the face from the non-face-facing side (outside). This reduces the gap between the mask body 10 and the face at both sides of the mask body 10, improving the mask's functions, such as blocking foreign matter and preventing droplets emitted by the wearer from scattering. Furthermore, because the ear loops 20a are not attached to the face-facing side of both sides of the mask body, i.e., the face side, the ends of the ear loops 20a do not come into direct contact with the wearer's face while wearing the mask, reducing discomfort.

[0062] <Medicine application area and surface> The mask 1 according to this embodiment uses a chemical agent to provide additional functions in addition to the original functions of a mask described above. The chemical agent may be applied directly to at least the mask body 10. The function of the chemical agent may be to act on the mask body 10 to change the properties of the mask body 10, thereby improving the wearing comfort, or to have a beneficial effect on the user's skin while wearing the mask 1 or during the wearing action, for example, by contacting or adhering to the skin, or by volatilizing the chemical agent. More specifically, the function of the chemical agent may be moisturizing, skin care, improving smoothness (smoothing the mask surface), adding fragrance, providing a cooling sensation, providing a warming sensation, etc. Among these, a chemical agent that provides one or more of the functions of moisturizing, skin care, and improving smoothness is preferable.

[0063] Examples of the agent include one or more of wax, MPC polymer, glycerin, diglycerin, polyethylene glycol with an average molecular weight of 200 to 1000, sorbitol, propylene glycol, 1,3-butylene glycol, glycine betaine, pyrrolidone carboxylic acid, pyrrolidone carboxylate, maltitol, sodium lactate, etc. Agents containing the above ingredients are effective in reducing friction between the skin and the mask 1 and improving slippage. When the agent is used as a slippage improver, it is preferable to include one or more of the above-mentioned wax, MPC polymer, and glycerin. Although overlapping with the above specific ingredients, examples of the agent include one or more of glycerin, polyhydric alcohols, vitamins, animal and vegetable oils and fats, plant extracts, fatty acid ester compounds, petroleum hydrocarbons, alkyl ethoxylates, polysiloxanes, polysaccharides such as glycosaminoglycans, etc. Agents containing the above ingredients have a high moisturizing effect on the skin.

[0064] The medication is applied to at least the face-facing side of the mask body 10, constituting a medication-application surface AF. Because the medication is applied to the face-facing side of the medication-application surface AF, the medication can easily come into contact with the face, allowing for effective use of medication that exerts its effect through direct contact with the face. Note that, for ease of explanation, the medication-application surface AF is shown in gray (matt finish) in Figures 1 to 3, but the medication applied to the medication-application surface AF is discontinuous.

[0065] The area ratio of the drug-applied portion (drug-applied portion, described in detail below) to the entire drug-application surface AF is not particularly limited, but is preferably 10 to 80%. An area ratio in this range can enhance the effect of the drug and reduce the possibility of excessive drug application causing stickiness or impairing the inherent filtering performance and shape retention of the material of the mask body 10.

[0066] When viewed over the entirety of the medication application surface AF, the basis weight of the applied medication is preferably 0.01 gsm to 1.0 gsm, and more preferably 0.05 gsm to 0.5 gsm. By maintaining a basis weight within this range, the effectiveness of the medication can be enhanced, stickiness caused by excess medication can be suppressed, and the filtering performance, shape retention, etc. of the mask body 10 can be maintained.

[0067] In this embodiment, the mask body 10 is folded back at the upper and lower sides toward the non-face-facing side, forming an upper folded portion 11U and a lower folded portion 11L. Therefore, as shown in FIG. 1, the drug-application surfaces AF of the upper folded portion 11U and the lower folded portion 11L are exposed on the non-face-facing side. By exposing the drug-application surface AF on the non-face-facing side in this manner, the feel of the non-face-facing side of the mask body 10 when the user touches it is improved during wearing or during the wearing action. Furthermore, before use, the ear loops 20a, 20a are at least partially in contact with the drug-application surface AF (FIG. 1), so the drug may also adhere to the ear loops 20a, 20a. More specifically, the drug transfers to the surfaces of the ear loops 20a, 20a that are non-face-facing when worn (after the ear loops are unfolded), and the drug exerts its effect on the user's fingers when the user holds the ear loops 20a, 20a. For example, if the medication has a slip-improving effect, the feel when holding the ear loops 20a, 20a will be improved. Furthermore, when providing masks, multiple masks 1 are often stacked in the thickness direction and packaged in a resin film or the like. In this case, if one mask has a medication application surface AF on the side not facing the face, the medication application surface AF can also be attached to the face-facing side of the mask stacked adjacent to the one mask.

[0068] In this embodiment, the ear loops 20a, 20a arranged on the side not facing the face face the drug application surface AF at the upper and lower parts of the mask body 10 in the joining regions 50, 50 at both ends of the mask 1 in the lateral direction D2. That is, in the embodiment of Fig. 1, the drug is disposed between the mask body 10 and the ear loops 20a, 20a at the upper and lower parts of the joining regions 50, 50. In such a case, depending on the type of drug, the joining method, etc., the joining strength of the joining regions 50, 50 may be reduced by the drug.

[0069] In contrast, in this embodiment, the drug on the drug-application surface AF is formed discontinuously and with a predetermined area ratio. FIGS. 5 and 6 show examples of drug application patterns on the drug-application surface AF. FIG. 5 is a view of the mask body 10 shown in FIG. 1 as seen from the side not facing the face, with the positions of the ear loops 20a, 20a indicated by dashed lines. FIG. 6 is a view of the mask 1 as seen from the side facing the face. In FIGS. 5 and 6, small joints included in the joint regions 50, 50 are omitted and indicated by diagonal lines. In the example shown in FIGS. 5 and 6, the drug application pattern is formed as a plurality of drug-application portions 41, 41, ... spaced apart from one another. The multiple drug-application portions 41, 41, ... are scattered and spaced apart across the entire drug-application surface AF. Areas other than the drug-application portions 41, 41, ... are drug-application target areas to which no drug is applied.

[0070] In this embodiment, the area ratio of such medicinal application portions 41, 41, ... in the bonding region 50 of the medicinal application surface AF, i.e., the ratio of the total area of ​​the medicinal application portions 41 to the area of ​​the region that is both the medicinal application surface AF and the bonding region 50, is 70% or less. The area ratio of the medicinal application surface AF in the bonding region 50 may be the ratio of the total area of ​​the medicinal applications 41, 41, ... included in the bonding region 50, 50 to the total area of ​​the bonding regions 50, 50 on the mask 1. From the viewpoint of preventing a decrease in the bonding strength in the bonding region 50, the area ratio of the medicinal application portions 41 in the bonding region 50 of the medicinal application surface AF may be preferably 60% or less, more preferably 50% or less, and even more preferably 30% or less.

[0071] The medicinal-application surface AF may have regions with varying densities of the medicinal-application sections 41, 41, .... That is, the medicinal-application surface AF may be divided into regions where the medicinal-application sections 41, 41, ... are sparsely formed and regions where the medicinal-application sections 41, 41, ... are densely formed. When dividing the medicinal-application surface AF into regions, for example, the medicinal-application sections 41, 41, ... may be sparsely formed in the bonded regions 50, 50, and the medicinal-application sections 41, 41, ... may be densely formed in regions other than the bonded regions 50, 50. In such cases, the area ratio of the medicinal-application sections 41 in the bonded regions 50 of the medicinal-application surface AF may be 10% or less, 5% or less, or 0%.

[0072] On the other hand, it is also possible to eliminate variations in density of the drug-applied portions 41, 41, ... within the drug-applied surface AF. For example, as shown in Figures 5 and 6, the drug-applied portions 41, 41, ... can be regularly arranged in the vertical direction D1 and the horizontal direction D2, so that variations in density of the drug-applied portions 41, 41, ... within the drug-applied surface AF are eliminated. In this case, there is no need to divide the drug-applied portions 41, 41, ... into regions to achieve variations in density, such as by sparsely distributing the drug-applied portions 41, 41, ... in the bonding region 50 and densely distributing the drug-applied portions 41, 41, ... in other regions, and thus the formation of the drug-applied surface AF is not complicated. In other words, to divide the drug-applied portions into regions, it is necessary to detect the position where the bonding region 50 is planned to be formed during the formation process of the mask body 10 and apply the drug to that region so that the area ratio of the drug-applied portions 41, 41, ... is sparse or zero. However, this is not necessary if the drug-applied portions 41, 41, ... are not divided into regions. In this way, when the drug is applied uniformly across the entire drug application surface AF, i.e., when the drug application portion 41 is not divided into sparse and dense areas, from the viewpoint of improving the effect of the drug, the area ratio of the drug application portion 41 in the bonding region 50 may preferably be 5% or more, more preferably 10% or more, and even more preferably 30% or more.

[0073] 5 and 6, the drug-applied portions 41, 41, ... are formed spaced apart from one another, but it is preferable that they are spaced apart from one another at least in the vertical direction D1, and preferably in both the vertical direction D1 and the horizontal direction D2. This allows the drug-applied portions 41, 41, ... to be two-dimensionally scattered across the entire drug-applied surface AF, which maintains the effect of the drug while also preventing a decrease in the filtering performance, etc., of the mask body 10.

[0074] In this way, when the medicinal application portions 41, 41, ... are formed spaced apart from one another, the circle-equivalent diameter c of one medicinal application portion 41 can be 1 to 15 mm. The circle-equivalent diameter of one medicinal application portion 41 refers to the diameter of a perfect circle having the same area as the area of ​​the medicinal application portion 41. In addition, the distance d in the horizontal direction D2 between the medicinal application portions 41, 41, ... adjacent in the horizontal direction D2 x (Fig. 6) may be 10 to 40 mm. The distance d in the vertical direction D1 between the drug-applied portions 41, 41, ... adjacent to each other in the vertical direction D1 y (Fig. 6) may be about 5 to 20 mm.

[0075] Furthermore, the distance d between the medicine application portions 41, 41, ... in the lateral direction D2 x is larger than the circle-equivalent diameter c of one drug-applied portion 41, that is, d x >c is preferable, and d x It is more preferable that the distance d between the drug-applied portions 41, 41, ... in the longitudinal direction D1 is d y is larger than the circle-equivalent diameter c of one drug-applied portion 41, that is, d y >c is preferable, and d x >2c. This relationship allows the medicinal-application areas 41, 41, ... to be more dispersed, making it easier to achieve an area ratio of the medicinal-application areas 41, 41, ... in the joining area 50 of the medicinal-application surface AF of 70% or less. In addition, the spacing d xand the circle equivalent diameter c, even if the drug-applied areas 41, 41, ... on the drug-applied surface AF are not divided into regions of sparseness (for example, if specific areas of the drug-applied surface AF are not selected to make the drug-applied areas 41, 41, ... sparse), the drug-applied areas 41, 41, ... within the bonding area 50 of the drug-applied surface AF are not changed in area ratio of the drug-applied areas 41, 41, ..., and therefore a decrease in bonding strength in the bonding area 50 can be prevented.

[0076] Furthermore, the above interval d x is greater than the length w of the bonding region 50 in the horizontal direction D2 (width of the bonding region 50), i.e., d x >w is preferable, and d x It is more preferable that w > 2w. Because of the above relationship, even if the medicinal-applied areas 41, 41, ... on the medicinal-applied surface AF are not divided into regions with a high or low density, the medicinal-applied areas 41, 41, ... are less likely to be arranged within the bonding area 50, and therefore a decrease in the bonding strength in the bonding area 50 can be prevented.

[0077] 5 and 6, the medicinal substance-applied portions 41, 41, ... are arranged in a staggered pattern, but they may also be arranged in a grid pattern, for example. However, arranging the medicinal substance-applied portions 41, 41, ... in a staggered pattern is preferable because it allows the medicinal substance-applied portions 41, 41, ... to be scattered two-dimensionally on the medicinal substance-applied surface AF.

[0078] The means for applying the agent may be contact or non-contact. Specific examples include spray, paintbrush, bar coater, gravure coater, flexo coater, roll coater, inkjet printing, etc. Among these, application by a flexo coater is preferred because it allows accurate positioning of multiple discontinuous agent application portions and provides a stable application amount.

[0079] As described above, the mask body 10 comprises a plurality of laminated sheets. More specifically, the mask body 10 comprises, from the face-facing side to the non-face-facing side, an inner sheet (face-facing sheet) 11, an intermediate sheet 12, and an outer sheet 13 (FIG. 3). Here, as shown in FIGS. 1 to 3, one entire surface of the inner sheet 11 can be made into a drug-application surface AF, and the drug-application surface AF can be positioned so as to face the face. In this way, when making one entire surface of the inner sheet 11 into a drug-application surface AF, the drug can be applied to the entire surface at the stage of preparing the long material for forming the inner sheet 11, which reduces the complexity of the manufacturing process and increases business efficiency.

[0080] Furthermore, as shown in FIGS. 1 to 3, when the inner sheet 11 is folded at its upper and lower ends to form an upper folded portion 11U and a lower folded portion 11L, the drug-application surface AF of the inner sheet 11 is exposed on the side not facing the face. In this embodiment, the drug-application surface AF is continuous from the face-facing side to the edge of the end in the longitudinal direction D1 and to the side not facing the face. Therefore, when the user touches the edge of the upper and / or lower end, the user touches the drug-application surface AF, and the drug can be applied to the face or fingers while wearing the mask 1 and during the putting-on motion. For example, if the drug improves the feel of the mask by improving its smoothness or other properties, the feel of the drug on the user's face or fingers can be improved.

[0081] <Mask body manufacturing and mask manufacturing> FIG. 7 is a schematic diagram illustrating a manufacturing example of the mask body 10 and a manufacturing example of the mask 1. As described above with reference to FIG. 3, the mask body 10 has, from the face-facing side to the non-face-facing side, an inner sheet (face-facing sheet) 11, an intermediate sheet 12, and an outer sheet 13, in this order. To manufacture the mask body 10, for example, a long inner sheet (material for the inner sheet) 11A that will become the inner sheet 11, a long intermediate sheet (material for the intermediate sheet) 12A that will become the intermediate sheet 12, and a long outer sheet (material for the outer sheet) 13A that will become the outer sheet 13 are each unwound and stacked. Here, the width of the long inner sheet 11A, i.e., the length in the orthogonal direction Dv that is orthogonal to the conveying direction (longitudinal direction of the elongated body) Dt, may be shorter than the widths of the long intermediate sheet 12A and the long outer sheet 13A. After the inner sheet elongated body 11A, the intermediate sheet elongated body 12A, and the outer sheet elongated body 13A are stacked to form a laminate, the laminate, i.e., the three sheets, can be folded together to form the pleated structure 15. Furthermore, by folding both edges of the inner sheet elongated body 1A that protrude in the orthogonal direction Dv from the intermediate sheet elongated body 12A and the outer sheet elongated body 13A toward the center in the orthogonal direction Dv, toward the outer sheet elongated body 13A, the mask main body elongated body 10A can be obtained.

[0082] The face-facing side of the inner elongated sheet body 11A, or the side opposite the outer elongated sheet body 13A during transport, can be the aforementioned drug-application surface AF. Therefore, by folding back both edges of the inner elongated sheet body 11A, the drug-application surface AF is exposed on the outer elongated sheet body 13A side, i.e., the side not facing the face. In the illustrated example, the drug-application surface AF is formed on only one side (the face-facing side) of the inner elongated sheet body 11A. By making the drug-application surface AF of the inner elongated sheet body 11A the face-facing side, it is possible to prevent the drug from being distributed between the inner elongated sheet body 11A and the surface facing the other sheets constituting the mask body 10, thereby reducing the bonding strength between the sheets constituting the mask body 10.

[0083] After the elongated mask body 10A is formed in this manner, the elongated ear loop sheet 20A that will become the ear loop sheet 20 is placed on the side of the elongated mask body 10A that does not face. The elongated mask body 10A and the elongated ear loop sheet 20A are then joined in the thickness direction across the boundaries between the ear loop sheets 20, 20 included in the elongated ear loop sheet 20A, forming a pre-cut joining region 50A. The stacked and joined elongated mask body 10A and the elongated ear loop sheet 20A are then cut at the boundaries between the ear loop sheets 20, 20 to obtain the mask 1.

[0084] Thus, the mask 1 according to this embodiment can be manufactured by the following procedure: forming a medicinal application surface AF on at least the face-facing side, and then joining the ear loop sheet 20 including a pair of ear loops to form the joining region 50. Here, the medicinal application surface AF is a surface on which a plurality of discontinuous medicinal application portions are formed, as described above. Furthermore, the area ratio of the medicinal application portions in the joining region 50 of the medicinal application surface AF is 70% or less. Therefore, one embodiment of the present invention may be a method for manufacturing a mask, which includes forming a medicinal application surface on at least the face-facing side of the main body, on which a plurality of discontinuous medicinal application portions are formed, and then joining a pair of sheet-like ear loops at joining regions to each lateral end of the face-facing or non-face-facing side of the main body, so that the medicinal application surface faces the sheet-like ear loops in at least a portion of the joining region, and the area ratio of the medicinal application portions in the joining region of the medicinal application surface is 70% or less.

[0085] As described above, when the mask body 10, and thus the mask 1, is manufactured using the inner sheet elongate body 11A on which the drug-application surface AF has been formed in advance, the drug-application surface AF is formed before the pleat structure 15 is formed. Therefore, in the resulting mask 1, the density of the drug-application portions 41, 41, ... may vary from place to place in a plan view, or the drug-application portions 41, 41, ... may overlap each other. For example, a pattern of drug-application portions 41, 41, ... as shown in FIG. 8 is obtained. In this configuration, when the pleats 15 are unfolded in the vertical direction D1 while wearing the mask 1, the overlapping of the mask body 10 and the drug-application surface AF is eliminated, allowing the drug-application surface AF to face the face with no or minimal folds. Therefore, when worn, the evenly distributed drug-application portions 41, 41, ... can face the face.

[0086] <Modification> 9 and 10 show modified patterns of the drug-applied portions 41, 41, .... In the example shown in Figs. 9 and 10, the drug-applied portions 41, 41, ... are also formed discontinuously, but are not completely spaced apart in the vertical direction D1 or the horizontal direction D2. Each drug-applied portion 41 has a rectangular shape with its long side in the horizontal direction D2, and these rectangular drug-applied portions 41, 41 are arranged in a staggered manner. In this example, the shape of the drug-non-applied portions between the drug-applied portions 41, 41 is also the same as the shape of the drug-applied portions 41.

[0087] In this example, the area ratio of the drug application portion in the bonding region 50 of the drug application surface AF is 70% or less, so that the effect of the drug can be maintained while preventing a decrease in the bonding strength between the ear hook portions 20a, 20a and the mask body 10 in the bonding region 50.

[0088] 11 and 12 show another modified pattern of the medicinal application portions 41, 41, .... In the example shown in Figures 11 and 12, the medicinal application portions 41, 41, ... are also discontinuous and spaced apart in the vertical direction D1, but in this example the medicinal application portions 41, 41, ... are continuous in the horizontal direction D2. In this example too, the area ratio of the medicinal application portions in the bonding region 50 of the medicinal application surface AF is 70% or less, so that it is possible to prevent a decrease in the bonding strength between the ear hooks 20a, 20a and the mask body 10 in the bonding region 50 while maintaining the effect of the medicinal agent.

[0089] When the mask 1 of this example is manufactured by the above-described manufacturing method in which the drug-application surface AF is formed in advance on one side of the inner sheet (face-facing sheet) 11, the drug-application areas 41, 41, ... can be formed continuously along the conveyance direction Dt of the long inner sheet body 11A (FIG. 7). Therefore, when forming the drug-non-application areas 41, 41, ..., it is not necessary to switch the applicator on and off, which reduces the complexity of the manufacturing process.

[0090] Although the present invention has been described above based on the embodiments, the present invention is not limited to these embodiments. Furthermore, the above embodiments can be variously changed, modified, substituted, added, deleted, and combined within the scope of the claims, and these also fall within the technical scope of the present invention.
