The present invention relates to a mask.

It is known that people wear masks to deal with hay fever, prevent infectious diseases, etc. Patent Document 1 discloses a scented mask that aims to alleviate the symptoms of hay fever and reduce discomfort when worn.

JP 2006-326006 A

However, because masks are used in contact with the wearer's face, there is the problem that the inside of the mask can easily become steamy due to the wearer's moist breath, and this discomfort is difficult to reduce with just fragrance. In particular, during the hot summer months, wearing a mask for long periods of time can lead to heatstroke.

The present invention was made in consideration of the above problems, and its purpose is to provide a mask that makes it easier for the wearer to feel the cool sensation.

The main invention to achieve the above object is:
A heat absorbing layer having a heat absorbing agent disposed therein;
A mask having a cooling layer in which a cooling agent is arranged and which is provided so as to face one side surface or the other side surface of the heat absorbing layer in a thickness direction,
A filter layer is provided.
The cooling layer is provided between the filter layer and the heat absorption layer,
The heat absorbing agent is non-volatile,
The mask is characterized in that the cooling agent is volatile .
Other features of the present invention will become apparent from the following detailed description of the present invention and the accompanying drawings.

The present invention provides a mask that allows the wearer to easily feel a cooling sensation.

FIG. 2 is a front view of the mask 2 in a worn state. FIG. 2 is a schematic diagram showing the mask 2 in a worn state as viewed from above. FIG. 8 is an enlarged view of a portion P in FIG. 7.

At least the following points will become apparent from the description of this specification and the accompanying drawings.
The mask is characterized by having a heat absorbing layer in which a heat absorbing agent is disposed, and a cooling sensation layer in which a cooling sensation agent is disposed and which is arranged so as to face one side surface or the other side surface in the thickness direction of the heat absorbing layer.

With such a mask, the heat absorbing agent can lower the surface temperature of the mask, allowing the wearer to feel the cool sensation of a disposable diaper, but the cooling agent also makes it easier for the wearer to feel the cool sensation before the surface temperature of the mask drops due to an endothermic reaction caused by contact with the wearer's moist breath, so the wearer can easily feel the cool sensation caused by the mask from the moment they put it on.

In such a mask, it is preferable that the surface of the mask closest to the skin is formed by the surface of one of the heat absorbing layers.

In such a mask, the heat absorbing agent lowers the surface temperature of the mask through an endothermic reaction caused by contact with the wearer's moist breath. By making one side of the heat absorbing layer the side closest to the skin, it becomes easier for the mask to come into contact with the wearer's breath, and the wearer can easily feel the surface temperature of the mask being lowered by the heat absorbing agent.

Such a mask has a mask body and ear hooks that are hung on the wearer's ears, the mask body has a vertical direction, a horizontal direction, and a thickness direction, the mask body has the heat absorption layer and the cooling layer, and at least one of the upper end and the lower end of the mask body has a folded part where the heat absorption layer or the cooling layer is folded back to the non-skin side, and it is preferable that the heat absorption agent is arranged on the skin side of the heat absorption layer in the non-folded part of the mask body that overlaps with the folded part in the thickness direction, or the cooling agent is arranged on the skin side of the cooling layer in the non-folded part of the mask body that overlaps with the folded part in the thickness direction.

With such a mask, the heat absorbing layer or cooling layer at the upper and lower ends of the mask body can be positioned close to the wearer's skin, making it easier for the wearer to feel the cooling sensation provided by the heat absorbing agent or cooling agent.

The mask has a mask body and ear hooks that are hung on the wearer's ears, the mask body has vertical, horizontal, and thickness directions, the mask body includes the heat absorption layer and the cooling layer, the surface of the mask closest to the skin is formed by the surface on one side of the heat absorption layer, at least one of the upper and lower ends of the mask body has a folded portion where the heat absorption layer and the cooling layer are folded back to the non-skin side, and it is desirable that the heat absorption agent is disposed on the skin-side surface of the heat absorption layer in the non-folded portion of the mask body that overlaps with the folded portion in the thickness direction.

With such a mask, the upper and lower ends of the mask body are in contact with the wearer's nose or chin, so the heat absorbing layer and cooling layer can be provided close to the wearer's skin, making it easier for the wearer to feel the cooling sensation provided by the heat absorbing agent and cooling agent.

In such a mask, it is desirable that the vertical length of the cooling layer in the folded portion is shorter than the vertical length of the heat absorbing layer.

With this type of mask, even if the cooling agent is encapsulated in microcapsules or is a volatile substance, the heat absorption layer can cover the cooling layer from either the non-skin side or the skin side at the folded-over portion, reducing the risk of losing the effect of the cooling agent.

The mask has a mask body and ear hooks that are hung on the wearer's ears, the mask body has a vertical and horizontal direction, and is provided with the heat absorption layer and the cooling layer, the heat absorption layer and the cooling layer are folded in a pleated shape at the vertical center by creases along the horizontal direction, the heat absorption layer and the cooling layer are joined in the pleated state at both sides of the horizontal direction of the mask body, the cooling agent is disposed over the entire cooling layer of the mask body, and it is desirable that the vertical center has a portion in which the basis weight of the cooling agent of the mask body is higher than the vertical ends.

With this type of mask, the vertical center of the mask body is close to the wearer's nostrils and mouth, making it easier for the wearer to feel the cooling effect of the cooling agent. By making this part a part with a high basis weight of the cooling agent, the wearer can more easily feel the cooling effect of the cooling agent.

In such a mask, it is desirable that the heat absorbing agent is disposed over the entire area of the heat absorbing layer of the mask body, and that the central portion in the vertical direction has a portion in which the basis weight of the heat absorbing agent of the mask body is greater than that of the ends in the vertical direction.

With this type of mask, the vertical center of the mask not only gets a cooling effect from the cooling agent, but also from the heat absorbing agent, making it easier for the wearer to feel the effects.

The mask has a mask body and ear hooks that are hung on the wearer's ears, the mask body has a vertical and horizontal direction, and is provided with the heat absorption layer and the cooling layer, and in the vertical center, the heat absorption layer and the cooling layer are folded in a pleated shape by creases along the horizontal direction, and on both sides of the mask body in the horizontal direction, the heat absorption layer and the cooling layer are joined in the pleated state, and it is desirable that the vertical center has a portion in which the basis weight of the cooling agent in the mask body is higher on both sides of the mask body in the horizontal direction than on the vertical end portions.

With this type of mask, both sides of the mask body in the left-right direction come into contact with the wearer's cheeks, so by making these parts areas with a high basis weight of cooling agent, the wearer can feel the cooling sensation more easily.

In such a mask, it is desirable that the central portion in the vertical direction has a portion in which the basis weight of the heat absorbing agent in the mask body is higher on both sides of the mask body in the left-right direction than on the ends in the vertical direction.

With this type of mask, the vertical center of the mask at both ends of the mask body in the left-right direction that come into contact with the wearer's cheeks not only receives the cooling effect of the cooling agent, but also the cooling effect of the heat absorbing agent, making it easier for the wearer to feel the effects.

The mask has a mask body and ear hooks that are hung on the wearer's ears, the mask body has a top-bottom and left-right direction, a pair of sheet parts that cover the right and left sides of the wearer's face, respectively, and a joint that joins the pair of sheet parts, the pair of sheet parts each having the heat absorption layer and the cooling layer, the cooling agent is disposed over the entire area of the pair of sheet parts, and it is desirable that the basis weight of the cooling agent disposed in the cooling layer of the mask body is higher in the center in the left-right direction than at the ends in the left-right direction.

With this type of mask, the cooling effect of the cooling agent can be felt more clearly in the left-right center of the mask body, which is close to the wearer's nostrils and mouth.

In such a mask, it is desirable that the heat absorbing agent is disposed over the entire area of the heat absorbing layer of the pair of sheet portions, and that the basis weight of the heat absorbing agent disposed in the heat absorbing layer of the mask body portion is higher in the center in the left-right direction than at both ends in the left-right direction.

With this type of mask, the center of the mask in the left-right direction not only gets a cooling effect from the cooling agent, but also from the heat-absorbing agent, making it easier for the wearer to feel the effects.

In such a mask, it is desirable that the airflow resistance value of the heat absorbing layer is higher than the airflow resistance value of the cooling layer.

With such a mask, the wearer's breath (exhaled air) is more easily retained in the heat absorbing layer, which has a higher airflow resistance, making it easier for the heat absorbing agent to react with the wearer's breath, making it easier to lower the surface temperature of the mask using the heat absorbing agent.

It is desirable for such a mask to have a filter layer, and for the cooling layer to be provided between the filter layer and the heat absorbing layer.

With this type of mask, even if the cooling agent is encapsulated in microcapsules or is a volatile substance, the cooling layer is sandwiched between the filter layer and the heat absorption layer, reducing the risk of the cooling agent losing its effectiveness.

In such a mask, it is preferable that the cooling layer comprises microcapsules containing the cooling agent, and that the encapsulated cooling agent is exposed to the outside by physical damage to the microcapsules.

With such a mask, the wearer can experience the cooling effect of the cooling agent depending on when they wear it.

It is desirable for such a mask not to have a fragrance generator that dissolves in water and emits a fragrance.

With such a mask, even if the mask does not have a fragrance emitter, the wearer can easily feel the cooling sensation caused by the mask from the moment they put it on.

In such a mask, it is preferable that the heat absorbing agent is non-volatile and the cooling agent is volatile.

With this type of mask, the volatile cooling agent allows the wearer to feel the cooling effect of the cooling agent from the moment the mask is put on, while the non-volatile endothermic agent reduces the risk of the endothermic agent evaporating before the mask is even used, which would reduce the cooling effect, thereby increasing the duration over which the wearer feels the cooling sensation.

In such a mask, the heat absorbing layer is a layer in which the heat absorbing agent is disposed on a first nonwoven fabric, the cooling layer is a layer in which the cooling agent is disposed on a second nonwoven fabric, and it is desirable that at least the first nonwoven fabric contains hydrophilic fibers.

With this type of mask, the hydrophilic fibers of the first nonwoven fabric make it easier for moisture to be retained within the first nonwoven fabric, which makes it easier for the endothermic reaction of the heat-absorbing agent to occur, thereby enhancing the cooling effect.

====Present Embodiment====
In the following, as a mask of the present invention, a so-called pleated type disposable mask 1 (hereinafter also referred to as "mask 1") will be described as an example in the first embodiment, and a so-called cup type disposable mask 2 (hereinafter also referred to as "mask 2") will be described as an example in the second embodiment. The mask 1 and the mask 2 are different from masks made of cotton fibers such as gauze or synthetic fibers or masks made of urethane material that are repeatedly used while being washed, and are provided with filter members 11 and 41 (described later) as a filter layer for collecting virus droplets and bacterial droplets. The masks 1 and 2 are masks that are assumed to be used as disposable masks in order to prevent the collection effect of the filter members 11 and 41 from being reduced by washing. However, the mask of the present invention may be a mask made of cotton fibers such as gauze or synthetic fibers or a mask made of urethane material. It may also be a mask that does not have a filter layer. Furthermore, the mask may not have ear loops, but is composed only of a mask main body, and is fixed to the wearer's face by any fixing means such as an adhesive tape.

First Embodiment
Fig. 1 is a plan view of the disposable mask 1 of the first embodiment as seen from the non-skin side. Fig. 2 is a plan view of the mask 1 as seen from the skin side. Fig. 3 is a cross-sectional view of the mask body 10 taken along line II in Fig. 1. Note that Fig. 3 omits the welded parts 14. Each figure shows the mask 1 before use.

(Basic configuration of mask 1)
The mask 1 has a mask body 10 that can cover at least the mouth and nostrils of the wearer, and ear hooks 20 that are hung on the wearer's ears. The mask body 10 has a top-bottom direction, a left-right direction, and a thickness direction. In the thickness direction, the inside that faces the wearer's face is also called the skin side or skin-facing side, and the opposite outside is also called the non-skin side or non-skin-facing side.

Before use, the mask body 10 has a rectangular shape that is long in the left-right direction in a plan view from the thickness direction (FIGS. 1 and 2). The mask body 10 has a filter member (filter layer) 11, a skin-side nonwoven fabric (heat absorption layer) 17 provided on the skin-facing side of the filter member 11, and a non-skin-side nonwoven fabric (cooling layer) 18 provided between the filter member 11 and the skin-side nonwoven fabric 17.
In plan view, the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 have substantially the same size and shape.

The filter member 11 (also referred to as the "filter layer 11") is a member for capturing at least any fine particles such as virus droplets, bacterial droplets, pollen, etc. The filter member 11 of the mask 1 is a member that has a high effect of capturing fine particles such as virus droplets, bacterial droplets, pollen, etc.
Specifically, it is preferable that the filter member 11 is a member that satisfies at least one of the following: BFE (bacterial filtration efficiency test: test particle size: approximately 3 μm) is 95% or more, and VFE (viral filtration efficiency test: test particle size: approximately 1.7 μm) is 95% or more.

An example of the filter member 11 is a sheet of nonwoven fabric made of polyolefin fibers that has been dielectrically polarized (electret-treated). The electret treatment creates a dielectric state in which a predetermined amount of positive or negative charge is applied to the surface of the polyolefin fibers, resulting in a collection function.

The airflow resistance of the filter member 11 should be 0.45 kPa·s/m or less, and preferably 0.3 kPa·s/m or less. If the airflow resistance of the filter member 11 is higher than 0.45 kPa·s/m, the wearer may be more likely to feel stuffiness inside the mask 1, even if the mask 1 contains the heat absorbing agent 70 and cooling agent 80 described below. Therefore, by maintaining the air permeability of the filter member 11 at an appropriate level in addition to the cooling effect of the heat absorbing agent 70 and cooling agent 80, stuffiness inside the mask 1 can be improved even during hot summer months.

The airflow resistance of the filter member 11 can be measured by a 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) to obtain a sample. Then, using a Kato Tech Co., Ltd. air permeability tester (KES-F8) or an equivalent air permeability tester, the standard air flow rate is set to 2 cm/s and the air permeability resistance of the sample is measured. This measurement is performed multiple times (for example, five times), and the average value can be used as the air permeability resistance of the filter member 11.

Specifically, the filter member 11 may be a single nonwoven fabric sheet without seams, in which a meltblown nonwoven fabric containing polypropylene fibers, which are polyolefin fibers, and an electret-treated spunbond nonwoven fabric containing polypropylene fibers are integrally formed. The meltblown nonwoven fabric arranged on the skin side may have an average fiber diameter of 0.5 to 3 μm and a basis weight of 1.5 to 5 g/m2. The spunbond nonwoven fabric arranged on the nonskin side may have an average fiber diameter of 15 to 30 μm and a basis weight of 18 to 50 g/m2. The nonwoven fabric may be composed of only polypropylene fibers, or may be polypropylene fibers to which, for example, polyethylene fibers have been added. The nonwoven fabric on the nonskin side is not limited to spunbond nonwoven fabric, but may also be spunlace nonwoven fabric, air-through nonwoven fabric, or needle punch nonwoven fabric. However, the filter member 11 is not limited to the above, and may not be electret-treated. For example, the filter member 11 may be a member (such as a nanofilter) that has small gaps between fibers and captures virus droplets by adhering them to the gaps between the fibers.

The skin-side nonwoven fabric 17 is a heat-absorbing layer 17 in which a heat-absorbing agent 70 is disposed. Hereinafter, the skin-side nonwoven fabric 17 is also referred to as the "heat-absorbing layer 17." The skin-side nonwoven fabric 17 may be any nonwoven fabric in which a heat-absorbing agent 70 can be disposed. Preferably, the nonwoven fabric is soft to the touch, and an example of such a nonwoven fabric is a spunbond nonwoven fabric containing polypropylene fibers.

The non-skin side nonwoven fabric 18 is a cooling layer 18 in which a cooling agent 80 is disposed. Hereinafter, the non-skin side nonwoven fabric 18 is also referred to as the "cooling layer 18." The non-skin side nonwoven fabric 18 may be any nonwoven fabric in which the cooling agent 80 can be disposed. Preferably, the nonwoven fabric is a nonwoven fabric that feels good against the skin, such as a spunbond nonwoven fabric containing polypropylene fibers.

The mask 1 is a pleated type in which the filter member 11, the skin-side nonwoven fabric 17, and the non-skin-side nonwoven fabric 18 are folded in a pleated shape at creases F along the left-right direction in the vertical center of the mask body 10 to form folds. The mask body 10 shown in FIG. 3 has four creases F1 to F4 visible from the non-skin side and four creases F5 to F8 visible from the skin side. The creases F1, F2, F7, and F8 are mountain folds that convex upward, and the creases F3, F4, F5, and F6 are valley folds that convex downward. However, the number and orientation of the creases F are not limited to the configuration illustrated in FIG. 3.

As shown in FIG. 1 etc., before use, the mask 1 maintains a pleated folded shape, and the mask body 10 is in an almost flat state. The pleated folds F1 to F8 allow the mask body 10 to expand in the vertical direction, and also allow the non-skin side to protrude into an Ω shape. Therefore, as shown in FIG. 4, the wearer of the mask 1 can expand the mask body 10 in the vertical direction according to the length from the nose to the chin, and cover the mouth and nostrils with the mask body 10. FIG. 4 is a diagram showing the mask 1 being worn.

Additionally, the upper end 100X and the lower end 100Y of the mask body 10 have folded-back portions 101 in which the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 are folded back to the non-skin side, respectively. In the following description, the portion of the mask body 10 that overlaps with the folded-back portion 101 in the thickness direction is referred to as a non-folded portion 102. The folded-back portions 101 increase the strength of the upper and lower ends of the mask body 10.
In addition, the opening of the skin side nonwoven fabric 17, the non-skin side nonwoven fabric 18, and the filter member 11 can be suppressed.

The mask body 10 has welding parts 14 that join overlapping sheets together, for example, welding parts 14 by heat welding or ultrasonic welding. As shown in FIG. 1, etc., on both lateral sides of the mask body 10, a plurality of welding parts 14 that join the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 are provided along the vertical direction. In addition, at the upper and lower ends and the vertical center of the mask body 10, a plurality of welding parts 14 that join the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 are provided along the left and right direction. However, the pattern of the welding parts 14 is not limited to the one exemplified in FIG. 1. In addition, overlapping members may be joined together with an adhesive (for example, a hot melt adhesive).

As shown in FIG. 3, at the upper end of the mask body 10, a shape-retaining member 15 is disposed between the folded non-skin-side nonwoven fabric 18 at the folded-back portion 101 and the non-folded portion 102. The shape-retaining member 15 is a thin rectangular member that can be easily bent by the wearer and retains its shape unless an external force is applied again. Examples of the shape-retaining member 15 include those formed from flexible thermoplastic resin or metal pieces. The wearer of the mask 1 can deform the shape-retaining member 15 to fit the shape of his or her nose, which can prevent a gap from occurring between the upper end of the mask body 10 and the wearer's face. In addition, welding portions 14 are provided on both sides of the shape-retaining member 15 in the vertical direction, which prevents the shape-retaining member 15 from shifting out of position.

The ear hooks 20 are ring-shaped members extending from both sides of the mask body 10 in the left-right direction when worn. The ear hooks 20 are preferably made of a stretchable material, such as rubber bands, stretchable nonwoven fabrics, and stretchable films. Specifically, as shown in FIG. 2, the pair of ear hooks 20 of the mask 1 are made of stretchable nonwoven fabric, and each has an opening 21 for hanging on the ears in the center in the left-right direction and the up-down direction. In addition, when the mask 1 before use is viewed from the skin side, the ear hooks 20 are provided on both sides in the left-right direction so that they fit into the planar shape of the mask body 10. The ear hooks 20 are joined to the skin side of the mask body 10 at joints 16 located at both ends in the left-right direction. The joints 16 are along the up-down direction and join the stretchable nonwoven fabric (20) to the mask body 10. Before use, the pair of ear loops 20 are connected by a connecting portion 22 at the center in the left-right direction on the skin-facing side of the mask body 10. When wearing the mask, the wearer can break the connecting portion 22 and wear the mask 1 by hanging each ear loop 20 over both ears of the wearer, as shown in FIG. 4. Examples of joining the joints 16 include welding or joining with an adhesive.

(Mask 1 having heat absorbing layer 17 and cooling layer 18)
While wearing a mask can prevent the intrusion of virus droplets and other fine particles, it also creates the problem that the inside of the mask can easily become steamy due to the wearer's moist breath. Especially during hot summer months, the steam inside the mask can cause heatstroke.

In contrast, in the mask 1 of this embodiment, the heat absorbing layer 17 (skin side nonwoven fabric 17) containing the heat absorbing agent 70 and the cooling layer 18 containing the cooling agent 80 are adjacent to each other in the thickness direction, and the cooling layer 18 is provided so as to face the non-skin side of the heat absorbing layer 17. The heat absorbing agent 70 is an agent that reacts with water to cause an endothermic reaction. The cooling agent 80 is an agent that gives the wearer a cool or refreshing feeling when it comes into contact with the wearer's skin.

The heat absorbing layer 17 is a layer in which a heat absorbing agent 70 is arranged on the skin side nonwoven fabric (skin side nonwoven fabric 17), and the cooling layer 18 is a layer in which a cooling agent 80 is arranged on the nonwoven fabric on the non-skin side (non-skin side nonwoven fabric 18). The skin side nonwoven fabric 17 preferably contains hydrophilic fibers. More preferably, the skin side nonwoven fabric 17 contains 50% or more hydrophilic fibers. This makes it easier for the skin side nonwoven fabric 17 to retain moisture contained in the wearer's breath, and the heat absorbing agent 70 of the skin side nonwoven fabric 17 to come into contact with moisture, and the contact time is also longer. This makes it easier for an endothermic reaction to occur due to the heat absorbing agent 70.

Examples of hydrophilic fibers include regenerated cellulose fibers such as rayon, natural cellulose fibers such as cotton and crushed pulp, and semi-synthetic cellulose fibers such as acetate. Hydrophobic fibers (e.g., polyethylene fibers and polypropylene fibers) may also be modified to be hydrophilic by being subjected to a hydrophilic treatment. A fiber can be judged to be highly hydrophilic if the contact angle of the fiber is less than 90 degrees. However, it is not limited to the above, and the skin side nonwoven fabric 17 does not necessarily have to contain hydrophilic fibers.

The mask 1 is provided with a heat absorbing layer 1, so that the moist breath of the wearer comes into contact with the heat absorbing agent 70 in the skin-side nonwoven fabric 17, and the heat absorbing agent 70 reacts with heat to lower the surface temperature of the mask 1, thereby improving stuffiness inside the mask 1.

In particular, the mask 1 has a filter member 11, and the filter member 11 for collecting virus droplets and the like has lower breathability (higher airflow resistance value) than the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18. Therefore, compared to a mask such as gauze that does not have the filter member 11, the wearer's breath is less likely to be discharged outside the mask 1 while wearing the mask 1, and the space inside the mask 1 is more likely to be sealed. In other words, the wearer's exhaled breath and the heat-absorbing agent 70 are less likely to pass through the filter member 11 and are more likely to remain inside the mask 1. In contrast, by providing the mask 1 with the heat-absorbing agent 70, the surface temperature of the mask 1 can be lowered by contact between the wearer's breath and the heat-absorbing agent 70, improving the stuffiness inside the mask 1 and making it easier for the wearer to feel a cool sensation inside the mask 1. In addition, the wearer's breath easily circulates the breath containing the heat-absorbing agent 70 inside the filter member 11, which also increases the durability of the cooling effect.

In addition, the outer peripheral edge of the mask is usually in close contact with the wearer's skin, but a space is likely to form between the mask and the wearer in the center of the mask. Therefore, in a mask that provides a cool-to-the-touch sensation, the wearer's skin is less likely to come into contact with the moisturizing agent in the center of the mask (nostrils and mouth area), which is prone to becoming steamy due to the wearer's breath, and the wearer is less likely to feel the cool sensation. In contrast, by utilizing the endothermic reaction of the heat-absorbing agent 70, the mask is less likely to be affected by the outside air temperature, and the surface temperature of the mask 1 can be lowered even during the hot summer months, thereby improving the steaminess inside the mask 1. In addition, in the mask 1 of this embodiment, the surface temperature of the mask 1 is lowered, so the wearer can feel the cool sensation even in areas where the mask 1 and the wearer's skin are not in contact. In particular, the wearer can feel the cool sensation even in the center of the mask 1 (nostrils and mouth area), which is prone to becoming steamy due to the wearer's breath but is prone to becoming steamy due to the wearer's skin and is prone to becoming steamy.

However, if the mask 1 only had the heat absorbing layer 17 (heat absorbing agent 70) and did not have the cooling layer 18 (cooling agent 80), it would take a certain amount of time for the moisture in the wearer's breath to come into contact with the heat absorbing agent 70, causing the heat absorbing agent 70 to undergo an endothermic reaction and lower the surface temperature of the mask 1. This means that the wearer may feel stuffy from wearing the mask 1 from the time they put on the mask 1 until the endothermic reaction lowers the surface temperature of the mask 1.

Therefore, the mask 1 includes not only the heat absorbing layer 17 but also the cooling layer 18. The cooling agent 80 of the cooling layer 18 can give the wearer a cooling sensation by contacting the wearer's skin, so that when the mask 1 is worn, the outer peripheral edge of the mask 1 directly contacts the wearer's skin, causing the cooling agent 80 to come into contact with the wearer's skin, or, if the cooling agent 80 is a volatile substance, the volatilized cooling agent 80 comes into contact with the wearer's skin, allowing the wearer to feel the cooling sensation caused by the cooling agent 80.
As shown in FIG. 3, the mask 1 allows the volatilized cooling agent 80 to pass through the heat absorption layer 17 provided on the skin side of the cooling layer 80 and reach the wearer's skin, thereby allowing the wearer to feel the effect of the cooling agent 80.

In other words, when the wearer puts on the mask 1, he/she can first feel a cool sensation or a refreshing sensation due to the cooling agent 80 in the cooling layer 18. Then, he/she can feel the drop in the surface temperature of the mask 1 due to the endothermic reaction of the heat absorbing agent 70. Therefore, the wearer can feel a cool sensation from the moment he/she puts on the mask 1, which improves stuffiness caused by wearing the mask 1, reduces shortness of breath, and also makes it possible to prevent the occurrence of heat stroke. In addition, the wearer can feel the cooling effect of the cooling agent 80 immediately after putting on the mask 1, and can feel the cooling effect of the heat absorbing agent 70 after a predetermined time has passed, so that the wearer can get a cooling effect for a longer period of time immediately after putting on the mask 1 than a mask equipped with only the heat absorbing agent 70 or only the cooling agent 80.

The heat absorbing agent 70 (heat absorbing component) preferably contains one of sugar alcohols and sugars. Examples of sugar alcohols include xylitol, erythritol, dextrose, sorbitol, etc. Examples of sugars include trehalose, sucrose (cane sugar), lactose (milk sugar), maltose (malt sugar), etc. These heat absorbing agents 70 are safe even when they come into contact with the mouth of a person wearing the mask 1. The heat absorbing agent 70 may contain a solvent component that dissolves or disperses the cooling component, if necessary.

The cooling agent 80 preferably contains a cooling component that stimulates the cold sensation receptors (temperature-sensitive TRP channels) of the wearer's skin without absorbing heat itself, thereby making the wearer feel a cold sensation. If necessary, it may contain a solvent component that dissolves or disperses the cooling component. Examples of the cooling agent 80 (cooling component) include menthol (e.g., l-menthol, etc.); menthol derivatives (e.g., menthyl lactate, menthyl glyceryl ether, etc.); methyl salicylate; and essential oils derived from plants such as mint and eucalyptus. By using such a cooling agent 80 that stimulates the cold sensation receptors, the wearer is more likely to feel a cold sensation. It is preferable to use a substance as the cooling agent 80 that can make the wearer feel the cold sensation caused by the cooling agent 80 more quickly than the time it takes for the endothermic reaction of the heat absorbing agent 70 to lower the surface temperature of the mask 1.

As described above, the filter member 11 is a sheet of nonwoven fabric made of polyolefin fibers that has been dielectrically polarized (electret-treated). In this way, the filter member 11, which has a collection function due to electric charge, has its collection function reduced by the adhesion of alcohol. Therefore, when the above-mentioned filter member 11 is adopted, it is preferable that the heat absorbing agent 70 and the cooling agent 80 do not contain alcohol. By doing so, it is possible to prevent the collection effect of the filter member 11 from being reduced. For example, it is preferable that the solvent contained in the heat absorbing agent 70 and the cooling agent 80 is a water-based solvent. Also, for example, when a solution in which an endothermic component is dissolved and dispersed in an alcohol-based solvent is applied to the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18, it is preferable that the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 are merged with the filter member 11 after the alcohol-based solvent is evaporated in the manufacturing line of the mask 1. In this way, it is preferable that the heat absorbing agent 70 and the cooling agent 80 in the state in which they are arranged in the mask 1 do not contain alcohol.

It is also preferable that the cooling agent 80 is a volatile substance, and the heat absorbing agent 70 is a non-volatile substance. The volatile cooling agent 80 volatilizes immediately after the mask 1 is used, making it easier to provide a cool or refreshing feeling to the wearer's skin, while the non-volatile heat absorbing agent 70 reduces the risk of the effect of the heat absorbing agent 70 being reduced because the heat absorbing agent 70 does not volatilize before the mask 1 is used. In addition, since the time when the cooling agent 80 exerts its cooling effect and the time when the heat absorbing agent 70 exerts its cooling effect can be shifted, the wearer can feel the cooling effect for a long time from immediately after putting on the mask 1. The volatile cooling agent 80 is a substance that becomes a gas in a general living environment and has a boiling point of less than 100°C. The non-volatile heat absorbing agent 70 is a substance that does not become a gas in a general living environment and has a boiling point of 100°C or higher.

The heat absorbing agent 70 may be liquid or solid (including gel, powder, etc.). The heat absorbing layer 17 of the mask 1 is provided with microcapsules containing the liquid heat absorbing agent 70. The membrane material of the microcapsules containing the heat absorbing agent 70 of the mask 1 is broken (broken) by physical stimuli such as external pressure (impact, friction), exposing or releasing the heat absorbing agent 70 inside. The membrane material of the microcapsules containing the heat absorbing agent 70 of the mask 1 is urethane resin. The microcapsules in which the heat absorbing agent 70 is contained in the membrane material of the closed microcapsules are also called "heat absorbing agent 70". The heat absorbing agent 70 does not necessarily have to be contained in a microcapsule, and the liquid or solid heat absorbing agent 70 may be directly applied or sprayed on the nonwoven fabric (skin-side nonwoven fabric 17) as the heat absorbing layer 17.

The cooling agent 80 may be liquid or solid (including gel, powder, etc.). The cooling layer 18 of the mask 1 is provided with microcapsules containing the liquid cooling agent 80. As with the heat absorbing agent 70, the membrane material of the microcapsules that contain the cooling agent 80 collapses (breaks) due to physical stimuli such as external pressure (impact, friction), exposing or releasing the cooling agent 80 inside. The membrane material of the microcapsules containing the cooling agent 80 of the mask 1 is urethane resin, as is the microcapsule of the heat absorbing agent 70. The microcapsules in which the cooling agent 80 is contained in the membrane material of the closed microcapsules are also referred to as "cooling agent 80". The cooling agent 80 does not necessarily have to be contained in a microcapsule, and the liquid or solid cooling agent 80 may be directly applied or sprayed onto the nonwoven fabric (non-skin-side nonwoven fabric 18) as the cooling layer 18.

The heat absorbing agent 70 and the cooling agent 80 used in the mask 1 are encapsulated in microcapsules with a membrane material of urethane resin, but are not limited to this. Any material may be used as long as it has a predetermined strength that allows it to collapse (by impact or friction) due to external pressure (physical stimuli). For example, gelatin, gelatin-gum arabic, melamine resin, urea-formaldehyde resin, etc. may be used. These resins may be used alone or in combination of two or more types of resins. In addition, the microcapsules may be ones that release the heat absorbing agent 70 and the cooling agent 80 by breaking the membrane material due to physical or chemical stimuli such as heat, light, liquid, etc. By encapsulating the heat absorbing agent 70 and the cooling agent 80 in microcapsules, they are easily retained between the fibers of the nonwoven fabric of the heat absorbing layer 17 and the cooling layer 18.

As in this embodiment, the heat absorbing agent 70 and the cooling agent 80 are encapsulated in microcapsules, so that the liquid or solid heat absorbing agent 70 and the cooling agent 80 applied directly before wearing the mask 1 can be reduced in risk of slipping off the mask 1 or losing volatile substances such as the cooling agent 80 due to evaporation. When wearing the mask 1, it is preferable for the wearer to first lightly tap the entire mask body 10. By tapping, a predetermined physical stimulus (pressure) is applied, and the microcapsules of the heat absorbing layer 17 and the cooling layer 18 are broken (disintegrated), and the encapsulated heat absorbing agent 70 and the cooling agent 80 are exposed to the outside. A wearer who wears the mask 1 with the heat absorbing agent 70 and the cooling agent 80 exposed can easily obtain the effects of the heat absorbing agent 70 and the cooling agent 80. In addition, because the heat absorbing agent 70 and the cooling agent 80 are each enclosed in a microcapsule membrane made of the same material, the wearer can expose the heat absorbing agent 70 and the cooling agent 80 at the same time by simply tapping the mask 1 before use, making it easier for them to exert their effects.

The heat absorbing layer 17 and the cooling layer 18 can be formed in the same manner. For example, the cooling agent 80 may be kneaded into at least a part of the fibers constituting the non-skin side nonwoven fabric 18. In other words, the cooling agent 80 may be disposed in a stage prior to the formation of the non-skin side nonwoven fabric 18 by, for example, impregnating the fiber web prior to the formation of the non-skin side nonwoven fabric 18 with the cooling agent 80 (solution) or mixing the cooling agent 80 into the resin before forming the fibers. Also, a binder mixed with the cooling agent 80 may be applied to the fiber web. This makes it difficult for the cooling agent 80 to fall off the non-skin side nonwoven fabric 18, gradually exerting its function, and increasing the durability of the cooling effect of the cooling agent 80.

However, without being limited to the above, the cooling agent 80 may be disposed on the surface of the fibers that make up the non-skin side nonwoven fabric 18. For example, the cooling agent 80 may be applied to the non-skin side nonwoven fabric 18 by various known application methods such as spraying, roller coating, brushing, etc., or the non-skin side nonwoven fabric 18 may be immersed in the cooling agent 80 (solution).

The heat absorbing agent 70 may be disposed over the entire area of the skin side nonwoven fabric 17, or may be disposed on a portion of the plane of the skin side nonwoven fabric 17. The heat absorbing agent 70 may be disposed on the skin side nonwoven fabric 17 at a constant basis weight (amount per unit area: g/m2), or may be disposed at different basis weights depending on the area of the skin side nonwoven fabric 17.

The cooling agent 80 may be disposed over the entire area of the non-skin side nonwoven fabric 18, or may be disposed on a portion of the plane of the non-skin side nonwoven fabric 18. The cooling agent 80 may be disposed on the non-skin side nonwoven fabric 18 at a constant basis weight (amount per unit area: g/m2), or may be disposed at different basis weights depending on the area of the skin side nonwoven fabric 17.

It is also preferable that the heat absorbing layer 17 containing the heat absorbing agent 70 forms the surface of the mask 1 closest to the skin. Specifically, as in the mask body 10 of the mask 1 shown in FIG. 3, it is preferable that the heat absorbing layer 17 is disposed on the surface closest to the skin, the filter layer 11 is disposed on the surface closest to the skin, and a cooling layer 18 is provided between the heat absorbing layer 17 and the filter layer 11.

As described above, the heat absorbing agent 70 undergoes an endothermic reaction when it comes into contact with the moist breath of the wearer, lowering the surface temperature of the mask. Therefore, by providing the skin-side nonwoven fabric 17 containing the heat absorbing agent 70 on the side closest to the skin of the mask body 10, the heat absorbing agent 70 is more likely to come into contact with the wearer's breath, enhancing the cooling effect. In addition, because the endothermic reaction can occur close to the wearer's skin, when the surface temperature of the mask 1 drops, the wearer is more likely to feel a cooling sensation.

In addition, the cooling layer 18 is provided between the filter layer 11 and the heat absorption layer 17, so that the cooling layer 18 is sandwiched between the filter layer 11 and the heat absorption layer 17. Therefore, even if the cooling agent 80 is encapsulated in microcapsules and placed on the non-skin side nonwoven fabric 18, the microcapsules are less likely to fall off the cooling layer 18, and the risk of the effect of the cooling agent 80 being reduced can be reduced. Even if the cooling agent 80 is not encapsulated in microcapsules and the cooling agent 80 itself is applied to the non-skin side nonwoven fabric 18 as a liquid, the volatilization of the cooling agent 80 can be reduced by covering both sides of the cooling layer 18 with the filter layer 11 and the heat absorption layer 17, and the risk of the effect of the cooling agent 80 being reduced can be reduced.

Furthermore, it is preferable that the non-skin side of the filter layer 11 forms at least a part of the non-skin side of the mask body 10 (mask 1), the skin side of the heat absorption layer 17 forms at least a part of the skin side of the mask body 10 (mask 1), and a cooling layer 18 is provided between the filter layer 11 and the heat absorption layer 17. By doing so, even in a mask 1 that includes the filter layer 11, the number of sheets stacked in the thickness direction in the mask body 10 can be reduced, and the space inside the mask 1 can be made less likely to become stuffy.

However, the configuration of the mask body 10 is not limited to the above, and for example, another sheet may be disposed on the non-skin side of the filter layer 11, on the skin side of the heat absorption layer 17, or between the filter layer 11 and the heat absorption layer 17. In addition, the order in which the filter layer 11, the heat absorption layer 17, and the cooling layer 18 are laminated may be different.

It is preferable that the airflow resistance of the heat absorption layer 17 is higher than that of the cooling layer 18 (airflow resistance of the heat absorption layer 17 > airflow resistance of the cooling layer 18). This makes it easier to retain more of the wearer's breath (exhaled breath) while wearing the mask in the heat absorption layer 17, which has a high airflow resistance, and makes it easier to cause an endothermic reaction between the heat absorption agent 70 and the wearer's breath, making it easier to lower the surface temperature of the mask 1. The airflow resistance of the heat absorption layer 17 and the airflow resistance of the cooling layer 18 can be measured by known methods. For example, the above-mentioned method for measuring the airflow resistance of the filter member 11 can be used.

Furthermore, it is preferable that the airflow resistance value of the filter layer 11 is higher than that of the heat absorption layer 17. In other words, it is more preferable that the airflow resistance value of the filter layer 11 is higher than that of the heat absorption layer 17, and that the airflow resistance value of the heat absorption layer 17 is higher than that of the cooling layer 18 (airflow resistance value of the filter layer 11 > airflow resistance value of the heat absorption layer 17 > airflow resistance value of the cooling layer 18). By doing so, it is easier to promote the endothermic reaction between the wearer's breath, which is moderately held in the heat absorption layer 17, and the heat absorption agent 70 while maintaining the effect of collecting fine particles such as virus droplets, bacterial droplets, and pollen in the filter layer 11, so that the endothermic effect and its duration can be improved. In addition, it is possible to reduce the risk of the cooling agent 80 leaking (volatilizing) to the outside through the filter layer 11, so that the cooling effect and its duration can be improved.

More preferably, the heat absorbing agent 70 is applied to the skin side of the skin side nonwoven fabric 17. By arranging the heat absorbing agent 70 in a position close to the wearer's skin, the heat absorbing agent 70 is more likely to come into contact with the wearer's breath, promoting the endothermic reaction and enhancing the cooling effect. In addition, since the endothermic reaction occurs in a position close to the wearer's skin, the wearer is more likely to realize that the surface temperature of the mask 1 has dropped. Similarly, the cooling agent 80 is preferably applied to the skin side of the non-skin side nonwoven fabric 18. By arranging the cooling agent 80 on the side close to the wearer's skin, the cooling agent 80 is more likely to come into contact with the wearer's skin, making it easier for the wearer to realize the cooling effect of the cooling agent 80. However, without being limited to the above, the heat absorbing agent 70 may be applied to the non-skin side or both sides of the skin side nonwoven fabric 17, and the cooling agent 80 may be applied to the non-skin side or both sides of the non-skin side nonwoven fabric 18.

In addition, in the mask 1, the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 are folded into pleats at the vertical center of the mask body 10. When the mask 1 is worn, the pleats are spread out in the vertical direction at the horizontal center of the mask body 10. However, at both horizontal sides of the mask body 10, the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 are joined by the welding parts 14 in a pleated state. In addition, at the upper end 100X and the lower end 100Y, the filter member 11, the skin side nonwoven fabric 17, and the non-skin side nonwoven fabric 18 are joined by the welding parts 14 in a folded state over the entire horizontal area of the mask body 10.

In other words, the cross-sectional state shown in FIG. 3 is maintained on both left and right sides of the mask body 10 even when the mask 1 is worn. Specifically, at the upper and lower ends 100X and 100Y of the mask 1, the heat absorbing layer 17 is overlapped in two layers in the thickness direction by the folded-back portion 101, and the cooling layer 18 is overlapped in two layers in the thickness direction. In the vertical center, the heat absorbing layer 17 and the cooling layer 18 each have a portion where they are overlapped in three layers in the thickness direction by the pleats.

In addition, in the case of a mask having upper and lower folded portions 101 like mask 1, the "upper end 100X" of the mask body 10 is the upper folded portion 101, the "lower end 100Y" is the lower folded portion 101, and the "central portion 100Z" is the portion that does not have the folded portion 101 and is the portion between the upper end 100X and the lower end 100Y in the vertical direction. In the case of a mask that does not have folded portions 101 like mask 1, the uppermost portion (a portion that is 1/4 the length of the upper half of the upper half) when the length of the upper half of the mask body 10 in the vertical direction is divided into four is the "upper end", the lowermost portion (a portion that is 1/4 the length of the lower half of the lower half) when the length of the lower half of the mask body 10 in the vertical direction is divided into four is the "lower end", and the portion between the upper end and the lower end in the vertical direction is the "central portion". In addition, with regard to the left-right direction of the mask body 10, when the length of one side (left side) of the mask body 10 in the left-right direction is divided into four equal parts, the part furthest to one side (the part that is 1/4 the length of the left side of the left half) is the "side" of one side, and when the length of the other side (right side) of the mask body 10 in the left-right direction is divided into four equal parts, the part furthest to the other side (the part that is 1/4 the length of the right side of the right half) is the "side" of the other side, and the part between both sides is called the "center".

In the mask 1 having such pleated folds F, when the mask body 10 is formed, the cooling agent 80 is uniformly distributed over the entire area of the non-skin side nonwoven fabric 18, and then the folds F are formed. This allows for a portion in which the basis weight (g/m2) of the cooling agent 80 is higher in the vertical center portion 100Z where the non-skin side nonwoven fabric 18 overlaps in three layers compared to the upper and lower ends 100X, 100Y where the non-skin side nonwoven fabric 18 overlaps in two layers. Specifically, as shown in FIG. 3, the portion H of the mask body 10 before use where the non-skin side nonwoven fabric 18 overlaps in three layers has a higher basis weight of the cooling agent 80 than the upper and lower ends 100X, 100Y.

This allows the cooling effect of the central portion 100Z to be enhanced in the vertical direction of the entire mask body 10, compared to the upper and lower ends 100X, 100Y. When the mask 1 is worn, the pleats are expanded in the vertical direction in the central portion of the mask body 10 in the horizontal direction, but are not completely expanded, and the non-skin side nonwoven fabric 18 overlaps in three layers in some places, maintaining the portion H with a high basis weight of the cooling agent 80. In addition, when worn, the central portion 100Z in the vertical direction of the mask body 10 is close to the wearer's nostrils and mouth, so the cooling effect of the cooling agent 80 is easily felt. Therefore, by increasing the basis weight of the cooling agent 80 placed in that portion, the wearer can more easily obtain the cooling effect of the cooling agent 80.

Furthermore, by distributing the heat absorbing agent 70 uniformly over the entire area of the skin-side nonwoven fabric 17 and forming the pleated folds F, it is possible to provide a portion in which the basis weight (g/m2) of the heat absorbing agent 70 is higher in the vertical center portion 100Z where the skin-side nonwoven fabric 17 overlaps in three layers compared to the upper and lower ends 100X, 100Y where the skin-side nonwoven fabric 17 overlaps in two layers. As shown in FIG. 3, the portion H of the mask body 10 before use where the skin-side nonwoven fabric 17 overlaps in three layers is a portion where the basis weight of the heat absorbing agent 70 is higher than the upper and lower ends 100X, 100Y. Even when the mask 1 is worn, the pleats are expanded vertically in the horizontal center portion of the mask body 10, but are not expanded completely, and in some places the skin-side nonwoven fabric 17 overlaps in three layers, maintaining the portion H where the basis weight of the heat absorbing agent 70 is high.

By making the basis weight of the heat absorbing agent 70 in the central portion 100Z, as well as the cooling agent 80, higher than the basis weight of the heat absorbing agent 70 in the upper and lower ends 100X and 100Y, the cooling effect of the central portion 100Z can be further enhanced. The wearer's breath is more likely to come into contact with the heat absorbing agent 70 in the central portion 100Z near the nostrils and mouth, making it easier for the wearer to feel the effect of the heat absorbing agent 70 and to realize the cooling effect of the mask 1.

As described above, even when the mask 1 is worn, the mask body 10 has two layers of cooling layer 18 at both sides thereof in the left-right direction, due to the welded parts 14, and the upper and lower ends 100X and 100Y of the mask 1 have the folded parts 101, due to the cooling layer 18 overlapping in two layers in the thickness direction, and the central part 100Z in the vertical direction has a portion where the cooling layer 18 overlaps in three layers in the thickness direction due to the pleats (FIG. 3). Therefore, by forming the folds F after the cooling agent 80 is uniformly distributed over the entire area of the non-skin side nonwoven fabric 18, the basis weight (g/m2) of the cooling agent 80 in the central part 100Z in the vertical direction, where the non-skin side nonwoven fabric 18 overlaps in three layers, can be made higher than that of the upper and lower ends 100X and 100Y, where the non-skin side nonwoven fabric 18 overlaps in two layers. Similarly, on both sides of the mask body 10, the part H where the non-skin-side nonwoven fabric 18 of the mask body 10 overlaps in three layers before use is an area where the basis weight of the cooling agent 80 is higher than the upper and lower ends 100X, 100Y (Figure 3).

When worn, both left and right sides of the mask body 10 are in contact with or close to the wearer's cheeks. In the parts in contact with or close to the wearer's cheeks, the basis weight of the cooling agent 80 in the central part 100Z near the wearer's nostrils and mouth is made higher than the basis weight of the cooling agent 80 in the upper and lower ends 100X and 100Y, so that the wearer can easily feel the cooling effect of the mask in the central part 100Z near the wearer's nostrils and mouth. In particular, the ear loops 20 are joined to both left and right sides of the mask body 10. Therefore, the left and right sides of the mask body 10 are easily attached to the wearer's skin (cheeks) due to the stretching force of the ear loops 20, and the wearer can easily feel the cooling effect of the cooling agent 80.

Furthermore, by distributing the heat absorbing agent 70 uniformly over the entire area of the skin side nonwoven fabric 17 and forming the pleated folds F, the basis weight (g/m2) of the heat absorbing agent 70 can be made higher in the vertical center 100Z where the skin side nonwoven fabric 17 overlaps in three layers, compared to the upper and lower ends 100X, 100Y where the skin side nonwoven fabric 17 overlaps in two layers, on both sides of the mask body 10 in the left-right direction of the mask 1 having the pleated folds F. Similarly, the heat absorbing agent 70 is also higher in the part H where the skin side nonwoven fabric 17 of the mask body 10 before use overlaps in three layers than the upper and lower ends 100X, 100Y (Fig. 3).

By making the basis weight of not only the cooling agent 80 but also the heat absorbing agent 70 arranged in the center portion 100Z higher than the basis weight of the heat absorbing agent 70 arranged in the upper and lower ends 100X, 100Y on both sides of the mask body 10 in the left-right direction, the wearer's breath can come into contact with more heat absorbing agent 70 in the center portion 100Z near the nostrils and mouth in the portion that contacts the wearer's cheek or in the adjacent portion. Therefore, it becomes easier to obtain the cooling effect of not only the cooling agent 80 but also the heat absorbing agent 70, making it easier to feel the cooling effect of the mask 1.

It is possible to confirm that the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 contain the heat absorbing agent 70 and the cooling agent 80, respectively, by a known method. First, the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 to be measured are removed from the mask 1, and samples of a predetermined size are formed. The samples are subjected to component analysis using, for example, a gas chromatography device (Agilent 7890B or an equivalent device), to confirm whether the samples of the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 contain the heat absorbing agent 70 and the cooling agent 80, respectively. If the heat absorbing agent 70 and the cooling agent 80 are contained in microcapsules, the presence or absence of the microcapsules (heat absorbing agent 70 and cooling agent 80) can be confirmed by observing the samples of the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18 under an electron microscope.

In addition, the basis weight (g/m2) of the cooling agent 80 at the upper and lower end portions 100X, 100Y and the central portion 100Z of the non-skin side nonwoven fabric 18, and the basis weight (g/m2) of the heat absorbing agent 70 at the upper and lower end portions 100X, 100Y and the central portion 100Z of the skin side nonwoven fabric 17 can also be compared using the above-mentioned gas chromatography device.
(1) First, the non-skin side nonwoven fabric 18 to be measured is removed from the mask 1 and separated into an upper end portion 100X, a lower end portion 100Y, and a central portion 100Z. The separated upper end portion 100X, lower end portion 100Y, and central portion 100Z are further cut into small samples of a predetermined size (e.g., vertical x horizontal = 20 mm x 40 mm, etc.).
(2) Next, the finely cut sample is immersed in a specific solvent, etc., to dissolve the microcapsules, and a mixture of the cooling sensation agent 80 (a component with a cooling sensation effect) and other components (solvent, etc.) is extracted from the sample.
(3) The mixture extracted for each sample is subjected to component analysis using a gas chromatography device. Then, for each sample, the peak value of the cooling agent (component with a cooling effect) and the peak values of other components (solvent, etc.) are obtained, and the ratio of the peak value of the cooling agent to the peak values of the other components (peak value of cooling agent/peak value of other components) is calculated. This ratio corresponds to the amount of cooling agent contained in the sample.
(4) Finally, by calculating the average value of the proportion of cooling agent (peak value of cooling agent/peak value of other components ≒ amount of cooling agent 80) for each of the multiple samples constituting the upper end portion 100X, the lower end portion 100Y, and the central portion 100Z, the average value can be calculated and compared as equivalent to the basis weight of the cooling agent 80 in the upper end portion 100X, the lower end portion 100Y, and the central portion 100Z.
Furthermore, in the case where the cooling sensation agent 80 is encapsulated in microcapsules or not, samples of a predetermined size are cut out from the portion of the non-skin side nonwoven fabric 18 to be compared, the cooling sensation agent 80 is removed from the cut-out samples, the weight difference before and after removing the cooling sensation agent 80 is calculated, and the differences are compared to compare the differences as the difference in basis weight of the cooling sensation agent 80 of each sample. For example, in the case where the cooling sensation agent 80 is encapsulated in microcapsules, samples of a predetermined size are cut out from the portion of the non-skin side nonwoven fabric 18 to be compared, the weight of each sample is measured in a dry state, the microcapsules are dropped by a fluid (water flow or wind flow), the weight of each sample is measured again in a dry state, the difference in weight before and after dropping the microcapsules is calculated, and the differences are compared to compare the differences as the basis weight of the cooling sensation agent 80 of each sample.
The same applies to the comparison of the basis weight (g/m2) of the heat absorbing agent 70 at the upper and lower end portions 100X, 100Y and the central portion 100Z of the skin side nonwoven fabric 17.

As shown in FIG. 3, it is preferable that a heat absorbing agent 70 is disposed on the skin side 102A of the non-folded portion 102 that overlaps in the thickness direction with the folded portion 101 at the upper end 100X and the lower end 100Y of the mask body 10, i.e., on the skin side surface of the skin-side nonwoven fabric 17.

By folding the upper and lower end portions 100X, 100Y of the mask body 10 to the non-skin side, the heat absorbing layer 17 can cover the upper end portion 100X and the lower end portion 100Y of the mask body 10 from the skin side to the non-skin side. In other words, the skin-side nonwoven fabric 17 having the heat absorbing agent 70 disposed therein can be provided on the skin side at the upper and lower end portions 100X, 100Y of the mask body 10.
The upper end 100X (upper part) and the lower end 100Y (lower part) of the mask body 10 are the parts that come into contact with the nose, cheeks, and chin of the wearer when worn. Therefore, the endothermic reaction of the heat absorbing agent 70 is likely to occur in the areas close to the wearer's skin, and the wearer is likely to feel a cool sensation.

In addition, when the upper end 100X of the mask body 10 is folded back to the non-skin side, it is preferable that the heat absorbing agent 70 is also arranged on the non-skin side (outer side) 101A of the folded part 101 of the upper end, i.e., the non-skin side of the skin-side nonwoven fabric 17. The wearer's breath is warm, so the wearer's breath discharged to the outside of the mask body 10 tends to rise. Therefore, the breath discharged to the outside of the mask body 10 can come into contact with the heat absorbing agent 70 arranged on the non-skin side 101A of the upper end of the mask body 10. This allows the surface temperature near the upper end of the mask body 10 to be lowered, making it easier for the wearer to feel a cool sensation. In addition, the temperature of the breath discharged to the outside of the mask body 10 is also lowered, making it less likely for the wearer's glasses to fog up.

Furthermore, as shown in FIG. 3, in the folded portion 101, it is preferable that the vertical length 18X (18Y) of the cooling layer 18 is shorter than the vertical length 17X (17Y) of the heat absorption layer 17 (18X<17X, 18Y<17Y). When the cooling agent 80 is encapsulated in microcapsules as in the mask 1, the heat absorption layer 17 covers the cooling layer 18 from the non-skin side in the folded portion 101, and the heat absorption layer 17 covers the cooling layer 18 from both sides in the thickness direction, so that the risk of the microcapsules encapsulating the cooling agent 80 falling or being damaged before using the mask 1 can be reduced. In addition, when the volatile cooling agent 80 is not encapsulated in microcapsules and is arranged in a liquid or solid state in the non-skin side nonwoven fabric 18, the cooling agent 80 in the non-skin side nonwoven fabric 18 is covered by the heat absorption layer 17, so that the risk of volatilization of the cooling agent 80 in the non-skin side nonwoven fabric 18 can be reduced.

However, the above configuration is not limited. For example, the upper and lower ends of the mask body 10 may be folded back toward the skin side, or only one of the upper and lower ends of the mask body 10 may be folded back toward the non-skin side. Also, the heat absorbing agent 70 does not have to be disposed on the non-skin side of the upper folded portion 101.

In the above embodiment, the upper and lower ends of the heat absorption layer 17 and the cooling layer 18 are folded back to the non-skin side to form the folded back portion 101, but this is not limited thereto. At least one of the heat absorption layer 17 or the cooling layer 18 may be folded back to the non-skin side. For example, only the heat absorption layer 17 may be folded back to the non-skin side, and the heat absorption agent 70 may be disposed on the skin side 102A (the skin side surface of the heat absorption layer 17) of the non-folded portion 102 that overlaps with the folded back portion 101 in the thickness direction, and the cooling layer 18 may not be folded back to the non-skin side. Furthermore, in addition to the heat absorption layer 17 and the cooling layer 18, the filter member 11 may also be folded back.
In addition, the folded-back portion 101 is not limited to a portion folded back from the skin-facing side to the non-skin-facing side, but may be a portion folded back from the non-skin-facing side to the skin-facing side. Neither the heat-absorbing layer 17 nor the cooling layer 18 may be configured to be folded back toward either the non-skin-facing side or the skin-facing side.

As shown in FIG. 1 etc., it is preferable that the mask 1 has a shape-retaining member 15. The shape-retaining member 15 makes it difficult for gaps to form between the mask 1 and the wearer (face), and increases the degree of sealing of the space inside the mask 1. This makes it easier to keep the heat-absorbing agent 70 and the cooling agent 80 within the space inside the mask 1, thereby enhancing the cooling effect of the heat-absorbing agent 70 and the cooling agent 80, and also increases the contact time and circulation between the wearer's breath and the heat-absorbing agent 70, thereby enhancing the cooling effect and its duration. However, this is not limited to the above, and the mask 1 does not have to have a shape-retaining member 15.

In addition, in the mask body 10, it is preferable that the outer peripheral edge of the filter member 11 coincides with the outer peripheral edges of the skin-side nonwoven fabric 17 and the non-skin-side nonwoven fabric 18. In the mask 1 of this embodiment, as shown in FIG. 1, the left end 11c of the filter member 11 coincides with the left end 17c of the skin-side nonwoven fabric 17 and the left end 18c of the non-skin-side nonwoven fabric 18, and the right end 11d of the filter member 11 coincides with the right end 17d of the skin-side nonwoven fabric 17 and the right end 18d of the non-skin-side nonwoven fabric 18. In addition, as shown in FIG. 3, the upper end 11a of the filter member 11 coincides with the upper end 17a of the skin-side nonwoven fabric 17 and the upper end 18a of the non-skin-side nonwoven fabric 18, and the lower end 11b of the filter member 11 coincides with the lower end 17b of the skin-side nonwoven fabric 17 and the lower end 18b of the non-skin-side nonwoven fabric. Note that this does not include misalignment due to the thickness of the sheet of the upper and lower folded parts 101. This allows the heat absorbing agent 70 and the cooling agent 80 to be distributed over a wide range of the plane of the mask body 10, allowing the wearer to feel the coolness of the mask 1 over a wide range of the mask. In addition, the filter member 11 can be distributed over a wide range of the plane of the mask body 10, providing a collection effect. However, this is not limited to the above, and the outer periphery of the filter member 11 may be misaligned with the outer periphery of the skin side nonwoven fabric 17 and the outer periphery of the non-skin side nonwoven fabric 18.

Furthermore, it is preferable that the basis weight of the heat absorbing agent 70 and the cooling agent 80 in the filter member 11 is lower than that of the skin side nonwoven fabric 17, and more preferably, the heat absorbing agent 70 and the cooling agent 80 are not disposed in the filter member 11. This can prevent the collection function of the filter member 11 from being reduced due to the heat absorbing agent 70 and the cooling agent 80 being attached to the filter member 11.

The mask 1 of this embodiment has a mask body 10 in which the filter layer 11 (filter member 11), heat absorption layer 17 (skin side nonwoven fabric 17), and cooling layer 18 (non-skin side nonwoven fabric 18) are joined in the thickness direction, but is not limited to this. For example, the mask body 10 may be a mask in which only the heat absorption layer 17 and the cooling layer 18 are layered in the thickness direction, or the filter layer 11, heat absorption layer 17, and cooling layer 18 may be layered in the thickness direction with other members.

The mask may also include a filter member 11, a heat absorbing layer 17 (skin side nonwoven fabric 17), and a cooling layer 18 (non-skin side nonwoven fabric 18), and may further include side sheets (not shown) arranged to sandwich both left and right sides of the mask body 10 from the skin side and non-skin side. A further heat absorbing agent 70 or cooling agent 80 may be disposed in this side sheet to improve the cooling effect. The side sheet is preferably a sheet with good breathability and texture, and examples of such materials include melt-blown nonwoven fabric, spunbond nonwoven fabric, SMS nonwoven fabric, and air-through nonwoven fabric.

In addition, the ear hooks 20 of the mask 1 of the first embodiment are formed by joining an elastic nonwoven fabric to the skin side, but this is not limited to this. For example, the ear hooks 20 may be formed by joining an elastic nonwoven fabric, rubber cord, etc. to the non-skin side. By joining the ear hooks 20 from the non-skin side, it is possible to prevent the ear hooks 20 from covering the mask body 10 from the skin side. Therefore, even at the left and right ends of the mask body 10, the heat absorption layer 17 in which the heat absorption agent 70 is arranged in a position close to the wearer's skin and the cooling layer 18 in which the cooling agent 80 is arranged can be brought closer to the wearer's skin (exposed to the skin side), making it easier for the wearer to feel the coolness. In particular, the part close to the joining part 16 to which the ear hooks 20 are joined is easily attached to the wearer's skin due to the stretching force of the ear hooks 20, making it easier for the wearer to feel the coolness.

Second Embodiment
Fig. 5A is a plan view showing a folded state of a disposable mask 2 (hereinafter also referred to as "mask 2") of a second embodiment, and Fig. 5B is a front view of the mask 2 in an unfolded state. Fig. 6 is a front view of the mask 2 in a worn state. Fig. 7 is a schematic view of the mask 2 in a worn state as seen from above. Below, 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 body 40 and ear hooks 50. When the mask 2 is in an unfolded state and when it is worn, the mask body 40 has up-down and left-right directions, with the side facing the wearer being the skin side (skin-facing side) and the opposite side being the non-skin side (non-skin-facing side). The mask body 40 also has a pair of sheet parts 43, 44 that cover the right and left sides of the wearer's face, respectively, a joint 45 that joins the pair of sheet parts 43, 44 to each other, a shape-retaining member 46, and a joint 47 that joins the ear hooks 50 to the pair of sheet parts 43, 44. The joints 45, 47 can be joined by known methods such as welding, squeezing, or adhesives.

With regard to the left-right direction of the mask body 10, when the length of one side (left side) of the mask body 40 in the left-right direction is divided into four equal parts, the part furthest to one side (the part that is 1/4 the length of the left half on the left side) is the "end" of one side, and when the length of the other side (right side) of the mask body 10 in the left-right direction is divided into four equal parts, the part furthest to the other side (the part that is 1/4 the length of the right half on the right side) is the "end" of the other side, and the area between both end parts in the left-right direction is called the "center".

As shown in FIG. 5A, the pair of sheet portions 43, 44 are overlapped with their skin-facing sides facing each other and joined by joints 45 along the edges 43a, 44a of the pair of sheet portions 43, 44. The edges 43a, 44a have curved shapes that convex outward. Therefore, when the folded (flat) mask 2 is unfolded so that the pair of sheet portions 43, 44 are separated (FIG. 5B), the mask body 40 assumes a three-dimensional shape (cup shape) with a concave skin-facing side.

The mask 2 is also a mask that is intended to be used as a disposable item, similar to the mask 1 of the first embodiment. As shown in FIG. 7, the mask body 40 (a pair of sheet parts 43, 44) has a filter member 41 as a filter layer that captures at least one of virus droplets and bacterial droplets, and a skin-side nonwoven fabric (heat absorbing layer) 42 that is provided on the skin side of the filter member 41 and has a heat absorbing agent 70 disposed therein. The filter member 41 of the mask 2 is a filter layer and also a cooling layer 41 in which a cooling agent 80 is disposed. As shown in FIG. 7, the heat absorbing layer 42 and the cooling layer 41 are adjacent to each other in the thickness direction, and the cooling layer 41 is provided so as to face the non-skin side of the heat absorbing layer 42. The heat absorbing agent 70 and the cooling agent 80 can be made of the same materials as those used in the mask 1 of the first embodiment, and in the mask 2, the heat absorbing agent 70 and the cooling agent 80 are also encapsulated in microcapsules and placed in the skin-side nonwoven fabric 42 and the filter member 41.

The mask 2 has a heat absorbing layer 42 and a cooling layer 41, so that the wearer can first feel a cool sensation or a refreshing sensation due to the cooling agent 80 of the cooling layer 41 when wearing the mask 2. Then, the wearer can feel the drop in the surface temperature of the mask 2 due to the endothermic reaction of the heat absorbing agent 70. Therefore, the wearer can feel a cool sensation when wearing the mask 2, improve stuffiness caused by wearing the mask 2, reduce shortness of breath, and suppress the occurrence of heat stroke. In addition, the wearer can feel the cooling effect of the cooling agent 80 immediately after wearing the mask 2, and can feel the cooling effect of the heat absorbing agent 70 after a predetermined time has passed, so that the wearer can get a longer cooling effect immediately after wearing the mask 2 than a mask equipped only with the heat absorbing agent 70 or a mask equipped only with the cooling agent 80. In particular, the mask 2 has a three-dimensional shape when worn, and a space is likely to be generated between the mask 2 and the wearer. Therefore, the volatilized cooling agent 80 remains in the space inside the mask 2 and is easily in contact with the wearer's skin, and the heat absorbing agent 70 makes it easier to lower the surface temperature of the mask 2, improving stuffiness inside the mask 2 and making it easier for the wearer to feel a cooling sensation.

The pair of sheet portions 43, 44 also have a shape-retaining member 46 at their upper ends between the filter member 41 and the skin-side nonwoven fabric 42. This increases the degree of sealing of the space inside the mask 2, improving the cooling effect and its duration. However, the mask 2 does not necessarily have to have the shape-retaining member 46.

The pair of sheet portions 43, 44 are joined at the joint 45 while overlapping on a plane (FIG. 5A). Therefore, as shown in FIG. 7, when the mask 2 is worn, the skin-side nonwoven fabric 42 remains in two layers in the region from the joint 45 to the edges 43a, 44a of the sheet portions 43, 44 (i.e., the seams of the sheet portions 43, 44).

Therefore, by distributing the cooling agent 80 uniformly over the entire area of the filter member 41, the area from the joint 45 to the sheet portions 43a and 44a can have a higher basis weight of the cooling agent 80 than the other areas. That is, the central portion in the left-right direction has a portion in which the basis weight of the cooling agent 80 is higher than both ends in the left-right direction. FIG. 8 is an enlarged view of the portion P in FIG. 7. As shown in FIG. 8, in the wearing state, the portion H80 of the cooling layer 41 (filter member 41) that overlaps with the joint 45 in the thickness direction (front-back direction of the wearer) is a portion in which the basis weight of the cooling agent 80 is higher than both ends in the left-right direction. Note that the portion H has a similar configuration even in the unfolded state shown in FIG. 5B. The central portion in the left-right direction of the mask 2 is close to the wearer's nostrils and mouth when worn, and is therefore prone to becoming steamy due to the wearer's breath, but by disposing a larger amount of the cooling agent 80, the wearer can easily feel the cooling effect of the cooling agent 80.

Similarly, by distributing the heat absorbing agent 70 uniformly in the skin-side nonwoven fabric 42, the area from the joint 45 to the edges 43a, 44a of the sheet portions 43, 44 can have a higher basis weight of the heat absorbing agent 70 than the other areas. In other words, the central area in the left-right direction has a portion in which the basis weight of the heat absorbing agent 70 is higher than both ends in the left-right direction. As shown in FIG. 8, in the worn state, the portion H70 of the heat absorbing layer 42 (skin-side nonwoven fabric 42) that overlaps with the joint 45 in the thickness direction (front-to-back direction of the wearer) is a portion in which the basis weight of the heat absorbing agent 70 is higher than the ends in the left-to-right direction. Note that the portion H has a substantially similar configuration in the unfolded state shown in FIG. 5B. The left-right center of the mask 2 is close to the wearer's nostrils and mouth when worn, and is therefore prone to becoming steamy due to the wearer's breath, but by distributing more heat absorbing agent 70 in the center, more of the heat absorbing agent 70 can be brought into contact with the wearer's breath, which makes it easier to promote the endothermic reaction and lower the surface temperature of the mask 2. The comparison method for the basis weights of the cooling agent 80 and the heat absorbing agent 70 can be performed in the same manner as described above.

In the central portion where the filter member 41 is layered in two layers, it is preferable that the cooling agent 80 is arranged continuously in the vertical direction from the upper end 40a to the lower end 40b of the mask body 40 at the joint between the sheet portions 43, 44. Similarly, it is preferable that the central portion where the skin-side nonwoven fabric 42 is layered in two layers has a portion where the heat absorbing agent 70 is arranged continuously in the vertical direction from the upper end 40a to the lower end 40b of the mask body 40.

In addition, in the mask 2 that assumes a three-dimensional shape (cup-like) when worn, a space is likely to form between the mask 2 and the wearer at the left-right center of the mask body 40. The evaporated cooling agent 80 is more likely to be retained in the space within the mask 2 at the left-right center of the mask body 40, so that the retained cooling agent 80 comes into contact with the wearer's skin, making it easier to give the wearer a cooling effect from the cooling agent 80. Furthermore, the wearer's breath that accumulates in the space within the mask 2 can come into contact with more endothermic agent 70, which makes it easier to promote an endothermic reaction and makes it easier to give the wearer a cooling effect from the endothermic agent 70.

The ear hooks 50 of the mask 2 are made of a stretchable sheet with openings 51 for hanging over the ears. As shown in FIG. 7, the ear hooks 50 are joined to the skin side of the mask body 40 by the joints 47. Even if the ear hooks 50 are joined to the skin side of the skin-side nonwoven fabric 42 on which the heat-absorbing agent 70 is arranged, the stretching force of the ear hooks 50 makes it easy to bring both ends of the pair of sheet parts 43, 44 into close contact with the wearer's skin, so that the heat-absorbing layer 42 and the cooling layer 41 can be brought closer to the wearer's skin, and the wearer can feel the cooling sensation. In addition, since the heat-absorbing agent 70 does not come into direct contact with the wearer's skin in the areas where it is highly in contact with the wearer's skin, irritation to the wearer's skin can be reduced.

In the mask 2, the filter member 41 is a cooling layer 41 including a cooling agent 80, but this is not limited to this. For example, the pair of sheet parts 43, 44 of the mask 2 may be configured to include a skin-side nonwoven fabric including a heat-absorbing agent 70, a non-skin-side nonwoven fabric including a cooling agent 80, and a filter layer including a filter member, which are stacked in order from the skin side. In addition, the pair of sheet parts 43, 44 may be configured to include a filter member including a heat-absorbing agent 70 and a skin-side nonwoven fabric including a cooling agent 80. In addition, the pair of sheet parts 43, 44 may not include a filter layer and may be composed of only a heat-absorbing layer and a cooling layer.
