[Patent Document 1] Japanese Patent Application Publication No. 2019-52400

[Problem to be solved by creation]

In the mask, there is a so-called problem that the space inside the mask is easily stuffy due to the moist breath of the wearer. Especially in the hot summer period, there is a concern about heat stroke due to long-term use of masks. Since the mask of Patent Document 1 is provided with a moisturizing agent, the wearer can obtain a cold sensation (contact cooling sensation) on the part of the skin in contact with the mask. However, the cooling sensation caused by the humectant is the cooling sensation caused by the temperature difference between the temperature of the humectant and the body temperature of the wearer. Therefore, the cooling sensation in contact with the moisturizer at the same temperature as the outside air temperature has a low cooling sensation effect and is not sufficient for improving the stuffiness in the mask. In addition, in general, although the outer peripheral end of the mask easily adheres to the wearer's skin, a space is likely to occur between the center part of the mask and the wearer. Therefore, in the central part of the mask, which tends to be stuffy due to the breath of the wearer, the wearer's skin is not easily in contact with the moisturizer, and it is difficult for the wearer to actually feel the cooling sensation.

===The first embodiment === Fig. 1 is a plan view of a disposable mask 1 (hereinafter also referred to as "mask") according to the first embodiment. Fig. 2 is a cross-sectional view of the mask 1 along the line I-I in Fig. 1. FIG. 3 shows a diagram of the wearing state of the mask 1.

＜Basic structure of mask 1＞ The mask 1 includes at least a mask body 10 that can cover the mouth and nostrils of the wearer, and an ear hook 20 that can be hung on the ears of the wearer. The mask body 10 has an up-down direction, a left-right direction, and a thickness direction. In the thickness direction, the inner side facing the wearer's face is also called the skin side or the skin side, and the outer side that is the opposite side is also called the non-skin side or the non-skin side.

The mask body 10 before use has a rectangular shape long in the left-right direction in a plan view (FIG. 1) viewed from the thickness direction. The mask body 10 has a filter member 11 that traps at least one of virus droplets and bacterial droplets, a skin-side nonwoven fabric (nonwoven fabric) 12 provided on the skin surface side of the filter member 11, and a side sheet 13.

The filter member 11 is a member having a high trapping effect of fine particles such as virus droplets, bacterial droplets, and pollen. Specifically, the filter member 11 is a member that satisfies at least one of BFE (bacterial filtration efficiency test: test particles of approximately 3 μm) of 95% or more and VFE (virus filtration efficiency test: test particles of approximately 1.7 μm) of 95% or more. ideal.

As the filter member 11, a sheet in which a non-woven fabric formed of polyolefin-based fibers is dielectrically polarized (electretized) can be exemplified. Through electret treatment, a predetermined amount of positive or negative charge is imparted to the surface of the polyolefin fiber to form a polarized dielectric state, thereby obtaining a complementary function.

Specifically, as the filter member 11, a meltblown nonwoven fabric containing polypropylene fiber as a polyolefin fiber and having been electretized, and a woven fabric containing polypropylene fiber and electretized can be exemplified. Adhesive nonwoven fabric is a one-piece nonwoven fabric sheet formed into an integral shape without seams. The average fiber diameter of the melt-blown nonwoven fabric arranged on the skin side may be 0.5 to 3 μm, and the basis weight may be 1.5 to 5 g/m ² . The spunbonded nonwoven fabric arranged on the non-skin side has an average fiber diameter of 15 to 30 μm and a basis weight of 18 to 50 g/m ² . In addition, the above-mentioned nonwoven fabric may be composed of only polypropylene fibers, or may be made of polypropylene fibers, for example, polyethylene fibers. In addition, the non-woven fabric on the non-skin side is not limited to spunbonded non-woven fabric, and may be water-jet non-woven fabric, hot-air non-woven fabric, or needle-punched non-woven fabric. However, it is not limited to the above, and the filter member 11 may not be electretized. For example, a member with a small fiber gap allows virus droplets or the like to adhere to the fiber gap, and the trapped member (nanofilter material, etc.) is used as the filter member 11.

A heat absorbing agent 30 is arranged on the nonwoven fabric 12 on the skin side. The skin-side non-woven fabric 12 may be a non-woven fabric in which the heat absorbing agent 30 can be arranged. Ideally, a non-woven fabric with a good touch on the skin may be sufficient, and spunbonded non-woven fabrics containing polypropylene fibers can be exemplified.

In the mask 1 of the first embodiment, the filter member 11 and the skin-side nonwoven fabric 12 are folded into pleats by the folds F along the left and right directions at the center of the mask body 10 in the vertical direction to form a pleated shape. Pleated type. The mask main body 10 shown in FIG. 2 has four creases F1 to F4 visible from the non-skin side, and four creases F5 to F8 visible from the skin side. The folds F1 to F3, F8 are mountain folds convex upward, and the creases F4, F5 to F7 are valley folds convex downward. However, the number and orientation of the folds F are not limited by the structure illustrated in FIG. 2.

The mask 1 before use maintains the pleated folded shape, and the mask body 10 is in an almost flat state. With the crease-like folds F, the mask main body 10 can be expanded in the vertical direction and can be raised in an omega shape on the non-skin side. Therefore, as shown in FIG. 3, the wearer of the mask 1 expands the mask body 10 in the vertical direction according to the length from the nose to the chin, and can cover the mouth and nostrils with the mask body 10.

Moreover, the upper end part and the lower end part of the mask main body part 10 respectively have the folded part 101 which folded the filter member 11 and the skin-side nonwoven fabric 12 toward the non-skin surface side. In addition, in the following description, the portion of the mask main body 10 overlapping with the folded portion 101 in the thickness direction is referred to as the non-folded portion 102. Due to the folded portion 101, the strength of the upper and lower end portions of the mask body 10 is improved. In addition, the opening of the filter member 11 and the skin-side nonwoven fabric 12 can be suppressed.

The side sheets 13 are provided on both sides of the mask body 10 in the left-right direction. A side sheet 13 is provided. The side sheet is formed from the skin side and the non-skin side on both sides in the left-right direction of the filter member 11 and the skin-side non-woven fabric 12 sandwiching the folds F maintaining the pleated shape and the up and down folded parts 101 . The side sheet 13 is preferably a sheet with good air permeability and good skin touch, and examples thereof include melt-blown non-woven fabrics, spun-bonded non-woven fabrics, SMS non-woven fabrics, and hot-air non-woven fabrics.

The mask main body 10 has a welded portion 14 integrated with the laminated sheets, for example, has a welded portion 14 by thermal welding, ultrasonic welding, or the like. As shown in FIG. 1, on both lateral sides of the mask body 10, a plurality of welded parts 14 for joining the filter member 11, the skin-side nonwoven fabric 12, and the side sheet 13 are provided along the vertical direction. The upper and lower ends of the mask main body 10 are collected at the center in the vertical direction, and a plurality of welded parts 14 for joining the filter member 11 and the skin-side nonwoven fabric 12 are provided along the left-right direction. However, the pattern of the welded portion 14 is not limited by the example illustrated in FIG. 1. In addition, the laminated sheets may be joined by an adhesive or the like (for example, a hot melt adhesive).

In addition, as shown in FIG. 2, at the upper end of the mask body 10, a shape retaining member 15 is arranged between the film member 11 in the folded portion 101 and the film member 11 in the non-folded portion 102. The shape-maintaining member 15 is a thin-plate rectangular member, which can be easily bent by the wearer and can maintain its shape without re-applying external examples. As the shape retaining member 15, a flexible thermoplastic resin, a metal sheet, or the like can be exemplified. The wearer of the mask 1 can deform the shape retaining member 15 according to the shape of the nose, and can suppress the occurrence of a gap between the upper end of the mask body 10 and the face of the wearer. In addition, fusion portions 14 are provided on both sides of the shape retaining member 15 in the vertical direction, so that the positional deviation of the shape retaining member 15 can be suppressed.

The ear hook portion 20 is a ring-shaped member extending from each of both sides in the left-right direction of the mask body portion 10. The ear hook part 20 is preferably a member having stretchability, and examples thereof include rubber cords, stretchable non-woven fabrics, stretchable films, and the like. The ear hook part 20 illustrated in FIG. 1 is a rubber cord, and is joined to the non-skin side of the mask body 10 by the joining part 16. One end of the rubber cord (20) is joined to the joint 16 of the upper end of the mask body 10, and the other end of the rubber cord (20) is joined to the joint 16 of the lower end of the mask body 10. The bonding of the bonding portion 16 can be exemplified by bonding or bonding by an adhesive.

(About mask 1 with endothermic 30) The mask 1 of the present embodiment is different from a mask formed of gauze or the like that is repeatedly used while washing, and includes a filter member 11 that traps virus droplets and bacteria droplets. Therefore, in order to prevent the reduction of the trapping effect of the filter member 11 due to washing, the mask 1 of the present embodiment is assumed to be used as a disposable mask.

In addition to suppressing the intrusion of ground particles such as virus droplets by wearing a mask, there is a problem that the space inside the mask is prone to sultry due to the so-called moist breath of the wearer. Especially in the hot summer period, there is a concern about heat stroke due to the sultry heat inside the mask.

Here, in the mask 1 of the present embodiment, the skin-side nonwoven fabric 12 on which the heat absorbing agent 30 is arranged is provided on the skin surface side of the filter member 11. The endothermic agent 30 refers to an agent that reacts with water to produce an endothermic reaction.

Therefore, the wearer's moist breath contacts the heat absorbing agent 30 of the skin-side non-woven fabric 12, and the heat absorbing agent 30 generates an endothermic reaction, which lowers the temperature of the space in the mask 1, so that the stuffiness in the mask 1 can be improved. As a result, it is possible to reduce breathing difficulties caused by wearing the mask 1 and suppress the occurrence of heat stroke.

In particular, the filter member 11 that supplements virus droplets and the like has lower air permeability than the skin-side nonwoven fabric 12 (high ventilation resistance value). Therefore, compared with a mask such as gauze that does not have the filter member 11, in the mask 1 of the present embodiment, the breath of the wearer is not easily discharged out of the mask 1, and the airtightness of the space in the mask 1 is high. That is, the breath exhaled by the wearer and the heat absorbing agent 30 do not easily pass through the filter member 11 and tend to stay in the space in the mask 1. Therefore, the contact time between the breath of the wearer and the heat absorbing agent 30 increases, the temperature of the space in the mask 1 is easily lowered, and the stuffiness in the mask 1 is easily improved. Therefore, the wearer easily feels the cooling sensation in the mask 1. In addition, because the breath containing the heat absorbing agent 30 is easily circulated inside the filter member 11 by the wearer's breathing, the durability of the cooling effect is also improved. With this, the wearer can easily feel the cooling sensation in the mask 1.

In addition, it is desirable that the mask 1 has a shape retaining member 15. In this way, a gap is less likely to occur between the mask 1 and the wearer (face), and the airtightness of the space in the mask 1 is improved. Therefore, the contact time and circulation of the breath of the wearer with the heat absorbing agent 30 increase, and the cooling effect and the durability thereof are improved. However, it is not limited to the above, and the mask 1 may not have the shape retaining member 15.

It is also different from the mask 1 of the present embodiment. For example, when the moisturizer placed in the mask is brought into contact with the wearer's skin to impart a cooling sensation (contact cooling sensation) to the wearer, the temperature of the moisturizer becomes the same as that of the wearer. The cooling sensation caused by the temperature difference of the body temperature. Therefore, when the outside temperature is high and the temperature of the moisturizer is the same as the outside temperature, the cooling effect is low, which is not sufficient for improving the stuffiness in the mask, and it is difficult for the wearer to actually feel the cooling sensation. Also, in general, although the outer peripheral end of the mask easily adheres to the wearer's skin, a space is likely to occur between the center part of the mask and the wearer. Therefore, in masks that provide a cool sensation on contact, the wearer’s skin and moisturizers are not easily in contact with the wearer’s skin in the central part (nostrils, mouth parts) of the mask that is likely to cause stuffiness due to the wearer’s breath, and it is difficult for the wearer to actually feel the cooling sensation. .

On the other hand, in the mask 1 of this embodiment, the endothermic reaction of the endothermic agent 30 is utilized. Therefore, it is not intended to be affected by the outside temperature, and the temperature of the space in the mask 1 can be lowered even in hot summer periods, and the stuffiness in the mask 1 can be improved. In addition, in the mask 1 of the present embodiment, since the temperature of the space in the mask 1 is lowered, the wearer can actually feel the cooling sensation even in the part where the mask 1 does not contact the wearer's skin. Particularly, although the wearer’s breath tends to become stuffy, even in the center part (nostrils, mouth part) of the mask 1 that is easily generated in the wearer’s skin space, the wearer can actually feel a cooling sensation.

It is desirable that the endothermic agent 30 (endothermic component) contains any one of sugar alcohols and sugars. Examples of sugar alcohols include xylitol, erythritol, glucose, and sorbitol. Examples of sugars include trehalose, sucrose (sucrose), lactose, and maltose. In the case of such a heat absorbing agent 30, it is safe even when it touches the mouth of the wearer of the mask 1.

In addition, the heat absorbing agent 30 may be mixed in at least a part of the fibers constituting the nonwoven fabric 12 on the skin side. That is, if the heat-absorbing agent 30 is arranged before the formation of the skin-side nonwoven fabric 12, for example, the fiber web before the formation of the skin-side non-woven fabric 12 may be immersed in the heat-absorbing agent 30 (solution), or after the heat-absorbing agent 30 is mixed into the resin. Form fibers. In addition, the adhesive mixed with the endothermic agent 30 may be applied to the fiber web.

In this way, the heat absorbing agent 30 does not easily fall off from the nonwoven fabric 12 on the skin side, and the function of the heat absorbing agent 30 is gradually exerted, so that the continuity of the cooling effect by the heat absorbing agent 30 is improved. In addition, it is possible to prevent the heat absorbing agent 30 from adhering to the filter member 11 from before the use of the mask 1 to reduce the collection function of the filter member 11.

However, it is not limited to the above, and the heat absorbing agent 30 may be arranged on the surface of the fiber constituting the skin-side nonwoven fabric 12. For example, various well-known coating methods such as a spray method, a roller coating method, and a brush coating method may be used to coat the skin-side non-woven fabric 12 with the heat-absorbing agent 30 or to impregnate the skin-side non-woven fabric 12 with the heat-absorbing agent 30 (solution). At this time, since the endothermic agent 30 easily comes into contact with the breath of the wearer, and the endothermic reaction is likely to occur, the cooling effect is improved.

More preferably, the heat absorbing agent 30 may be applied to the skin side of the skin-side nonwoven fabric 12. Furthermore, by disposing the heat absorbing agent 30 at a position close to the wearer, the heat absorbing agent 30 can more easily come into contact with the breath of the wearer, and the cooling effect is improved. In addition, since the endothermic reaction occurs at a position close to the wearer, the temperature of the space in the mask 1 is likely to drop, and the wearer is likely to actually feel a cooling sensation. However, it is not limited to the above, and the heat absorbing agent 30 may be applied to the non-skin side surface or both surfaces of the skin-side nonwoven fabric 12.

In addition, the endothermic agent 30 may be in a liquid form, or may be in a solid form (including gel form, powder form, etc.). In addition, microcapsules encapsulating the heat absorbing agent 30 may be arranged on the skin-side nonwoven fabric 12, and the heat absorbing agent 30 may be released by physical or chemical stimulation (for example, heat, pressure, impact, light, liquid, etc.). In addition, the endothermic agent 30 also contains a solvent for dissolving and dispersing an endothermic component having an endothermic effect.

In addition, the heat absorbing agent 30 may be arranged in the entire plane of the skin-side non-woven fabric 12 or may be arranged in a part of the plane of the skin-side non-woven fabric 12. In addition, the heat absorbing agent 30 may be arranged on the skin-side non-woven fabric 12 with a constant basis weight (amount per unit area: g/m ² ), and different basis weights may be arranged in accordance with the area of the skin-side non-woven fabric 12.

In addition, it is desirable that the skin-side nonwoven fabric 12 contains hydrophilic fibers. More preferably, the nonwoven fabric 12 on the skin side may contain 50% or more of hydrophilic fibers. In this way, the nonwoven fabric 12 on the skin side easily retains moisture contained in the breath of the wearer, and the heat absorbing agent 30 of the nonwoven fabric 12 on the skin side easily comes into contact with moisture, and the contact time becomes longer. Therefore, the endothermic reaction by the endothermic agent 30 is likely to occur, and the cooling effect is improved.

Examples of hydrophilic fibers include regenerated cellulose fibers such as rayon, natural cellulose fibers such as cotton and ground pulp, and semi-synthetic cellulose fibers such as acetate. In addition, hydrophobic fibers (for example, polyethylene fibers, polypropylene fibers, etc.) may be subjected to hydrophilic treatment, and may be modified to hydrophilic fibers. For the determination of hydrophilic fibers, for example, if the contact angle of the fiber is less than 90 degrees, it can be determined as a highly hydrophilic fiber. However, it is not limited to the above, and the skin-side nonwoven fabric 12 may not include hydrophilic fibers.

In addition, it is preferable that the non-skin side surface of the filter member 11 forms at least a part of the non-skin side surface of the mask main body 10, and the skin side surface of the skin-side nonwoven fabric 12 forms at least a part of the skin side surface of the mask main body 10. In this way, the number of sheets laminated in the thickness direction in the mask body 10 is reduced, and the space in the mask 1 can be made less likely to be stuffy. In the mask main body 10 of this embodiment, the area other than the both sides in the left-right direction where the side sheets 13 are arranged is composed of two sheets of non-woven fabric (the filter member 11 and the skin-side non-woven fabric 12).

In addition, in the above-mentioned case, the skin-side nonwoven fabric 12 on which the heat absorbing agent 30 is arranged is positioned on the skin-most side of the mask body 10. Therefore, the heat absorbing agent 30 easily comes into contact with the breath of the wearer, and the cooling effect is improved. In addition, since the endothermic reaction occurs at a position close to the wearer, the temperature of the space in the mask 1 is likely to drop, and the wearer is likely to actually feel a cooling sensation.

In addition, in the center of the mask body 10 in the left-right direction and the up-down direction, the side sheets 13 are not located here. In addition to being composed of two non-woven fabrics, the upper and lower folded parts 101 are not located here (pleated Although the crease F of is located here, the crease F is unfolded in the up and down direction in the wearing state). That is, in the part of the mask 1 where the wearer's nostrils and mouth are prone to sultry, the number of sheets laminated in the thickness direction is approximately two. Therefore, the space in the mask 1 can be made less sultry.

However, the structure of the mask body 10 is not limited to the above. For example, other sheets may be arranged on the non-skin side than the filter member 11, on the skin side than the skin-side nonwoven fabric 12, and between the filter member 11 and the skin-side nonwoven fabric 12. .

In addition, the ventilation resistance value of the filter member 11 may be 0.45 kPa•s/m or less, preferably 0.3 kPa•s/m or less. When the ventilation resistance value of the filter member 11 is higher than 0.45 kPa•s/m, even if the mask 1 has the heat absorbing agent 30, there is a concern that the wearer may easily feel the sultry heat in the mask 1. Therefore, in addition to the cooling effect of the heat absorbing agent 30, the air permeability of the filter member 11 can be appropriately maintained, and the stuffiness in the mask 1 can be improved even in hot summer periods.

However, it is desirable that the ventilation resistance value of the filter member 11 is higher than the ventilation resistance value of the nonwoven fabric 12 on the skin side. In this way, the breath of the wearer and the heat absorbing agent 30 stay moderately in the space inside the mask 1, and the contact time between the breath of the wearer and the heat absorbing agent 30 increases, so the heat absorbing effect and its continuity are also improved.

The measurement of the ventilation resistance value of the filter member 11 can be performed by a well-known method. For example, the filter member 11 is separated from the mask 1 using cold spray or the like, and the filter member 11 is cut into a predetermined size (for example, a circle with a diameter of 100 mm) as a sample. Then, use the air permeability testing machine (KES-F8) manufactured by Japan Kato Technology Co., Ltd. or an equivalent air permeability testing machine, and set the standard air permeability to 2 cm/s to measure the air resistance value of the sample. Such measurement is performed a plurality of times (for example, 5 times), and the average value thereof can be used as the ventilation resistance value of the filter member 11.

In addition, as described above, the filter member 11 of the present embodiment is a sheet in which a non-woven fabric made of polyolefin-based fibers is dielectrically polarized (electretized). In this way, the filter member 11 having a trapping function due to an electric charge reduces the trapping function due to the adhesion of alcohol.

Therefore, when the above-mentioned filter member 11 is used, it is desirable that the endothermic agent 30 does not contain alcohol. In this way, it is possible to prevent the collection effect of the filter member 11 from being reduced. For example, the solvent contained in the endothermic agent 30 is preferably an aqueous solvent. Also, for example, when the endothermic component is dissolved in an alcohol-based solvent and the dispersed solution is applied to the skin-side non-woven fabric 12, in the manufacturing line of the mask 1, after the alcohol-based solvent is vaporized, the skin-side non-woven fabric 12 and the filter member 11 are combined. Can. In this way, the heat absorbing agent 30 in the mask 1 may not contain alcohol.

In addition, the endothermic agent 30 is preferably non-volatile. In this way, it is possible to prevent the heat absorbing agent 30 from volatilizing on the filter member 11 before use of the mask 1, so that the heat absorbing agent 30 adheres to the filter member 11, and the trapping function of the filter member 11 is reduced. The non-volatile endothermic 30 is a substance that does not become a gas in a general living environment and has a boiling point of 100°C or higher.

In addition, the filter member 11 preferably has a lower basis weight than the skin-side nonwoven fabric 12, and it is more desirable that the filter member 11 is not provided with the heat absorber 30. In this way, many heat absorbing agents 30 are arranged on the nonwoven fabric 12 on the skin side close to the wearer. Therefore, the heat absorbing agent 30 easily comes into contact with the breath of the wearer, and the cooling effect is improved. In addition, since the endothermic reaction occurs at a position close to the wearer, the temperature of the space in the mask 1 is likely to drop, and the wearer is likely to actually feel a cooling sensation. In addition, it is possible to prevent the heat absorbing agent 30 from adhering to the filter member 11 to reduce the collection function of the filter member 11.

The comparison with the basis weight of the heat absorbing agent 30 arranged on the filter member 11 and the skin-side nonwoven fabric 12 can be performed by a known method. For example, cold spraying or the like is used to separate the filter member 11 and the skin-side nonwoven fabric 12 from the mask 1, and to sprinkle colored fine powders such as bamboo charcoal and cocoa powder, and then shake off the particles. Many particles adhere to the part where the endothermic 30 is arranged. Therefore, by comparing the amount of particles attached to the filter member 11 and the skin-side nonwoven fabric 12, the basis weight of the endothermic agent 30 can be compared.

In addition, steam may be applied to the filter member 11 and the skin-side nonwoven fabric 12 to compare the respective surface temperatures. Specifically, each of the filter member 11 and the skin-side nonwoven fabric 12 is cut to a predetermined size to prepare a sample, water is added to two containers such as a beaker, and the container is covered with each sample. Install a temperature sensor on the sample, put two containers covered from above with plastic wrap, etc., into a water tank heated to 40 degrees, and compare the temperature of each sample. A sample with a large basis weight of the endothermic 30 decreases the temperature of the sample due to the endothermic reaction of the endothermic 30 as time passes.

In addition, it may be confirmed that the heat absorbing agent 30 is applied to the skin side of the skin-side nonwoven fabric 12 by the above-mentioned method. For example, in the method of dispersing particles, as long as the particles adhere to the skin side of the skin-side non-woven fabric 12, it can be confirmed that the heat-absorbing agent 30 is applied to the skin side of the skin-side non-woven fabric 12. In addition, in the method of measuring the temperature by applying steam, the same non-woven fabric as the skin-side non-woven fabric 12, that is, the non-woven fabric in which the heat absorbing agent 30 is not provided, is prepared. When the temperature of the skin side of the skin-side non-woven fabric 12 is lower than the temperature of the non-woven fabric, it can be confirmed that the heat-absorbing agent 30 is applied to the skin side of the skin-side non-woven fabric 12.

In addition, in the mask main body 10, it is desirable that the outer peripheral end of the filter member 11 coincides with the outer peripheral end of the nonwoven fabric 12 on the skin side. In the mask 1 of the present embodiment, as shown in FIG. 1, the left end 11c of the filter member 11 coincides with the left end 12c of the skin-side nonwoven fabric 12, and the right end 11d of the filter member 11 coincides with the right end 12d of the skin-side nonwoven fabric 12. As shown in FIG. 2, the upper end 11 a of the filter member 11 coincides with the upper end 12 a of the skin-side non-woven fabric 12, and the lower end 11 b of the filter member 11 coincides with the lower end 12 b of the skin-side non-woven fabric 12. In addition, the positional deviation of the thickness of the sheet of the upper and lower folded portions 101 is not included. In addition, in the heads 101a and 101b on the center side in the vertical direction in the folded portion 101, the head of the filter member 11 and the head of the skin-side nonwoven fabric 12 may be shifted.

According to the above, the skin-side non-woven fabric 12 and the heat absorbing agent 30 can be arranged over a wide area of the plane of the mask body 10. Therefore, the temperature of the space in the mask 1 can be lowered in a wide range by the heat absorbing agent 30. In addition, the filter member 11 can be arranged in a wide area of the plane of the mask main body 10, and the trapping effect can be obtained. However, it is not limited to the above, and the outer peripheral end of the filter member 11 and the outer peripheral end of the skin-side nonwoven fabric 12 may be shifted.

In addition, in the mask 1 of the first embodiment, the filter member 11 and the skin-side nonwoven fabric 12 are folded in a pleat shape at the center of the mask body 10 in the vertical direction. When the mask 1 is worn, the pleated part is unfolded in the vertical direction at the center of the mask body 10 in the left-right direction. However, on both sides of the mask body 10 in the left-right direction, the filter member 11 and the skin-side nonwoven fabric 12 are folded in a pleated state by the welded portion 14. In addition, on both sides of the mask body 10 in the left-right direction, the upper and lower ends of the filter member 11 and the skin-side nonwoven fabric 12 are folded by the welded portion 14.

That is, at both sides of the mask body 10 in the left-right direction, the state of the cross section shown in FIG. 2 can be maintained even when the mask 1 is worn. Specifically, the skin-side nonwoven fabric 12 overlaps two layers in the thickness direction by the folded portion 101 at the upper and lower ends. The center part in the up-down direction has a part where the skin-side nonwoven fabric 12 overlaps three layers in the thickness direction by gathers.

Therefore, a certain amount of heat absorbing agent 30 is arranged on the skin-side non-woven fabric 12, and compared with the upper and lower ends of the skin-side non-woven fabric 12 overlapped with two layers, the skin-side non-woven fabric 12 is overlapped with three layers at the center in the vertical direction to increase the heat absorbing agent 30. Basis weight (g/m ² ).

The ear hooks 20 are joined to the upper and lower ends of both sides in the left-right direction of the mask body 10. Therefore, the upper and lower end portions are easier to adhere to the wearer's skin due to the extension force of the ear hook portion 20 than the center portion in the vertical direction, and the wearer is more likely to actually feel the cooling effect of the heat absorbing agent 30. On the other hand, since the center part in the vertical direction is close to the nostrils and mouth of the wearer, it is prone to stuffiness, and the heat absorbing agent 30 easily comes into contact with the moist breath of the wearer. Here, the basis weight of the endothermic agent 30 may be set as described above. In this way, on both sides of the mask body 10 in the left and right direction, the center in the vertical direction has a low degree of adhesion to the wearer’s skin, but because the wearer’s breath is more in contact with the heat-absorbing agent 30, Therefore, the cooling sensation effect is improved, and it is easy for the wearer to actually feel the cooling sensation. In addition, the center part in the up and down direction of the both sides in the left and right direction of the mask main body 10 is in contact with the cheek of the wearer although the degree of adhesion is lower than that of the upper and lower ends. Therefore, if the basis weight of the endothermic agent 30 is increased in this part, the wearer is likely to actually feel the cooling sensation.

In addition, when the mask 1 is worn, the pleated part is unfolded in the vertical direction at the center of the mask body 10 in the left-right direction, but it is not completely unfolded, and the skin-side non-woven fabric 12 is partially overlapped with three layers. Therefore, even in the center part in the left-right direction of the mask main body 10, the basis weight (g/m ² ) of the heat absorbing agent 30 becomes higher in the center part in the up-down direction compared with the up-down end part. Therefore, since the breath of the wearer comes into contact with more heat-absorbing agent 30, the cooling effect is improved.

In other words, in the mask 1 having pleated folds F, the skin-side nonwoven fabric 12 can be laminated in three layers in the thickness direction at the center of the mask body 10 in the vertical direction. Therefore, even if a certain amount of heat absorbing agent 30 is arranged on the skin-side nonwoven fabric 12, the basis weight of the heat absorbing agent 30 in the center portion in the vertical direction can be increased compared to the upper and lower ends of the mask body 10. As a result, the cooling effect of the center part of the up-down direction of the mask 1 can be improved.

Moreover, as shown in FIG. 2, it is preferable that the upper end part and the lower end part of the mask main body part 10 respectively have the folded part 101 which folded the filter member 11 and the skin-side nonwoven fabric 12 toward the non-skin surface side. Furthermore, it is preferable to arrange the heat-absorbing agent 30 on the skin side surface 102A of the non-folded portion 102 overlapping the folded portion 101 in the thickness direction, that is, on the skin side surface of the skin-side nonwoven fabric 12.

Folding the upper and lower ends of the mask body 10 toward the non-skin surface can prevent the filter member 11 from covering the skin side nonwoven fabric 12 from the skin side at the upper and lower ends of the mask body 10. That is, at the upper and lower ends of the mask body 10, the skin-side nonwoven fabric 12 on which the heat absorbing agent 30 is arranged can be exposed on the skin side. Therefore, since the endothermic reaction of the endothermic agent 30 occurs at a position close to the wearer, the wearer is likely to actually feel the cooling sensation. In particular, the upper and lower end portions of the mask body 10 are easier to adhere to the wearer's skin than the center portion in the up and down direction, so the wearer is more likely to actually feel the cooling sensation.

As mentioned above, when the upper end of the mask body 10 is folded toward the non-skin side, the non-skin side (outer side) 101A of the upper folded portion 101, that is, the non-skin side of the skin-side nonwoven fabric 12 is also It is desirable to be equipped with an endothermic agent 30.

Since the breath exhaled by the wearer is warm, the breath of the wearer discharged to the outside of the mask body 10 is likely to rise. Therefore, the breath discharged to the outside of the mask main body 10 can come into contact with the heat absorbing agent 30 arranged on the non-skin side surface 101A of the upper end of the mask main body 10. Therefore, the temperature in the vicinity of the upper end of the mask body 10 can be lowered, and the wearer can easily actually feel the cooling sensation. In addition, since the temperature of the breath discharged to the outside of the mask body 10 also drops, the wearer's glasses are less likely to fog up.

However, it is not limited by the above-mentioned structure. For example, the upper and lower ends of the mask body 10 may be folded toward the skin side, or only one of the upper and lower ends of the mask body 10 may be folded toward the non-skin surface. In addition, the heat absorbing agent 30 may not be arranged on the non-skin side of the upper folded portion 101.

In addition, the ear hook portion 20 (rubber string) of the mask 1 of the first embodiment is joined to the non-skin side surface of the mask body 10 by the joining portion 16. At this time, it is possible to prevent the ear hook portion 20 from covering the skin-side non-woven fabric 12 from the skin side. Therefore, the nonwoven fabric 12 on the skin side on which the heat absorbing agent 30 is arranged can be arranged at a position close to the wearer (it can be exposed on the skin side). Therefore, even at the joint portion 16 of the ear hook portion 20, the endothermic reaction of the heat absorbing agent 30 occurs at a position close to the wearer, so that the wearer is likely to actually feel a cooling sensation. In particular, the portion of the nonwoven fabric 12 on the skin side corresponding to the joint 16 of the ear loop 20 is easily adhered to the wearer's skin due to the elongation force of the ear loop 20, so that the wearer is more likely to actually feel the cooling sensation.

==Second Embodiment== Fig. 4A shows a top view of the disposable mask 2 (hereinafter also referred to as "mask") of the second embodiment in a folded state, and Fig. 4B is a front view of the mask 2 in an unfolded state. Fig. 5 is a front view of the mask 2 in a worn state. Fig. 6 is a schematic view of the mask 2 in a worn state viewed from above. Hereinafter, the parts of the mask 2 of the second embodiment that are different from the mask 1 of the first embodiment will be mainly described.

The mask 2 of the second embodiment has a mask main body 40 and an ear hook 50. The mask body 40 has an up and down direction and a left and right direction in the unfolded state of the mask 2 and the wearing state of the mask 2. The side facing the wearer is called the skin side (skin side), and the opposite side is called Non-skin side (non-skin side). In addition, the mask body 40 has a pair of sheet portions 43, 44 covering the right and left faces of the wearer, a joining portion 45 that joins the pair of sheet portions 43, 44 to each other, and a shape maintaining member 46, And the joint part 47 which joins the ear hook part 50 to the pair of sheet parts 43 and 44. The joining parts 45 and 47 can be joined by well-known methods such as fusion, pressing, and adhesive.

As shown in FIG. 4A, the pair of sheet parts 43, 44 are superimposed so that their skin side faces each other, by following the end edges 43a, 44a of the pair of sheet parts 43, 44 The joining portion 45 is joined. The end edges 43a, 44a have a curved shape convex toward the outside. Therefore, when the mask 2 in the folded state (planar shape) is unfolded so that the pair of sheet portions 43 and 44 are separated (FIG. 4B ), the mask body portion 40 becomes a three-dimensional shape (cup shape) in which the skin side surface is recessed.

In addition, the mask 2 of the second embodiment is assumed to be used as a disposable mask similar to the mask 1 of the first embodiment. Furthermore, the mask body 40 (a pair of sheet parts 43, 44) has as shown in FIG. 6 a filter member 41 that traps at least one of virus droplets and bacterial droplets, and a filter member 41 provided on the skin surface side of the filter member 41 , And the skin-side non-woven fabric (non-woven fabric) 42 on which the heat absorbing agent 30 is arranged.

Therefore, if the wearer's moist breath comes into contact with the heat absorbing agent 30 of the nonwoven fabric 42 on the skin side, the heat absorbing agent 30 generates an endothermic reaction and lowers the temperature of the space in the mask 2, so that the stuffiness in the mask 2 can be improved. In particular, the mask 2 of the second embodiment has a three-dimensional shape when worn, and a space is easily generated between the mask 2 and the wearer. Therefore, the temperature of the space in the mask 2 is lowered by the heat absorbing agent 30, and the wearer can easily actually feel the cooling sensation.

In addition, the pair of filter members 43 and 44 have a shape retaining member 46 at their upper ends, that is, between the filter member 41 and the skin-side nonwoven fabric 42. Therefore, the degree of airtightness of the space in the mask 2 is improved, and the cooling effect and the durability thereof are improved. However, the mask 2 does not have to have the shape retaining member 46.

In addition, the pair of filter members 43 and 44 are joined at the joining part 45 in a state where they are superimposed on a plane (FIG. 4A ). Therefore, as shown in FIG. 6, in the wearing state of the mask 2, the area from the joint 45 to the end edges 43a, 44a of the filter members 43, 44 (that is, the seam portion of the filter members 43, 44) is maintained The skin-side nonwoven fabric 42 is in a state where two layers are overlapped. Therefore, a certain amount of heat absorbing agent 30 is arranged on the skin-side non-woven fabric 42 so that the area from the junction 45 to the end edges 43a, 44a of the filter members 43, 44 can be set to a higher basis weight than other areas.的高基重部48。 The high base weight 48. In addition, the comparison method of the basis weight of the endothermic agent 30 can be performed in the same manner as the aforementioned comparison method.

In this way, in the wearing state of the mask 1 (FIG. 5 ), the center part 401 of the mask body 40 in the left-right direction has a high basis weight part 48 having a higher basis weight of the heat absorbing agent 30 than the both end parts 402 in the left and right direction. As ideal. In this way, in the left-right center part (nostril and mouth part) of the mask 2 which tends to be stuffy due to the breath of the wearer, more heat absorbing agent 30 can be brought into contact with the breath of the wearer, and the cooling effect is improved. Therefore, the temperature of the space in the mask 2 is lowered, the stuffiness in the mask 2 can be improved, and the wearer can easily actually feel the cooling sensation.

Furthermore, the skin-side non-woven fabric 12 overlaps two layers of the high basis weight portion 48 of the heat absorbing agent 30 (that is, the seam portion of the filter members 43 and 44), which is continuous in the vertical direction from the upper end 40a to the lower end 40b of the mask body 40 Just be configured.

The mask 2 of the second embodiment that has a three-dimensional shape (cup shape) when worn is likely to have a space between the mask body 40 and the wearer in the center of the mask body 40 in the left-right direction. Therefore, in the center part of the left-right direction of the mask main body part 40, the high basis weight part 48 of the heat absorption agent 30 may be made long in the up-down direction. In this way, the breath of the wearer staying in the space in the mask 2 can be brought into contact with more heat absorbing agent 30, and the cooling effect can be improved.

Moreover, the ear strap 50 of the mask 2 of 2nd Embodiment is a stretchable sheet which forms the opening 51 for ears. As shown in FIG. 6, the ear hook part 50 is joined to the skin side of the mask body 40 by the joining part 47. At this time, the skin side surface of the skin-side nonwoven fabric 12 on which the heat absorbing agent 30 is arranged is covered by the ear hook part 50. However, the part of the skin-side nonwoven fabric 12 to which the ear strap 50 is joined has a high degree of adhesion to the wearer's skin due to the extension force of the ear strap 50. Therefore, even if the heat absorbing agent 30 is covered with the ear hook 50, the wearer can actually feel the cooling sensation. In addition, in a portion where the adhesion to the wearer's skin is high, since the heat absorbing agent 30 does not directly contact the wearer's skin, the irritation to the wearer's skin can also be reduced.
