Description

[Technical Field]

[0001] The present invention relates to a mask that covers the wearer's nose and mouth and is less likely to become stuffy. [Background technology]

[0002] In recent years, the importance of masks that cover the wearer's nose and mouth has increased from the perspective of preventing the spread of coronavirus.

[0003] Conventional masks of this type have various structures. For example, Patent Document 1 listed below describes a mask comprising an outer covering part that covers the nose and mouth of the wearer, retained parts that are integrally and continuously formed with the outer covering part on the left and right sides of the outer covering part and are retained by the wearer's ears, an inner covering part that is provided on the surface of the outer covering part facing the wearer, a main seam formed by sewing together the upper and lower ends of the outer covering part and the inner covering part, and a pocket part that is formed between the outer covering part and the inner covering part by sewing together the main seam and that opens in the left and right directions.

[0004] However, when wearing a mask, the wearer's breath tends to get trapped inside the mask, causing the mask to become stuffy.

[0005] To solve the above problem, for example, Patent Document 2 below describes a ventilation device for a mask in which ventilation units are arranged on both the left and right side edges of a mask body that is worn to cover the nose and mouth of the face, and the ventilation units are connected by connectors along the face-facing surface of the mask body. The ventilation units have a frame-shaped body and comb-shaped clips arranged on both sides of the body, and are attached to the mask via the clips. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3229141 [Patent Document 2] Patent No. 6778349 Summary of the Invention [Problem to be solved by the invention]

[0007] The ventilation device for a mask described in Patent Document 2 has a complex structure because the ventilation unit is separate from the mask and must be attached to the mask via a clip. In addition, the ventilation unit touches the skin, which can make the device uncomfortable to wear.

[0008] On the other hand, the mask described in Patent Document 1 has one wide pocket that extends in the left-right direction of the mask and is open on both the left and right sides, but this pocket does not have any openings that communicate with the wearer's nose or mouth, so the wearer's exhaled breath cannot be exhausted.

[0009] Therefore, an object of the present invention is to provide a mask that can easily exhaust the wearer's exhaled air from inside the mask with a simple structure. [Means for solving the problem]

[0010] In order to achieve the above object, the mask of the present invention has an outer fabric and an inner fabric partially placed inside the outer fabric, and comprises a mask body that covers the wearer's nose and mouth, and ear loops that are connected in a loop shape to both sides of the mask body and are hooked onto the wearer's ears, the inner fabric is attached to the back side of the outer fabric, avoiding the area where at least the wearer's nose will be placed, and a pair of pockets surrounded by the outer fabric and the inner fabric are formed on both sides of the area where at least the wearer's nose will be placed, The pair Pocket Each Top and bottom edges In the inner fabric outer fabric Connected to Combined The inner fabric is not joined to the outer fabric in the portion between the pair of pockets, The pocket is characterized in that an opening that is not closed by the outer fabric and the inner fabric is provided at both the left and right ends of each pocket.

[0011] According to the above invention, the back side of the outer fabric, on both sides of the portion where at least the wearer's nose is placed, is surrounded by the outer fabric and the inner fabric. a pair Pockets are formed, and the left and right sides of each pocket Both At the end, there is an opening that is not blocked by the outer fabric and the inner fabric. each As a result, the wearer's exhaled air enters each pocket through an opening provided at the inner end of each pocket and is then exhausted to the outside of the mask through an opening provided at the outer end of each pocket, which makes it less likely for the exhaled air to become trapped inside the mask and makes it less likely for the mask to become stuffy.

[0012] Furthermore, since the pocket portion is formed integrally with the mask body using the outer fabric and the inner fabric, a mask that can reliably exhaust the wearer's exhaled air with a simple structure can be obtained.

[0013] Furthermore, each pocket can also contain a sheet-like material containing a cooling material or a sheet-like material containing a heat-generating material, making it possible to provide a mask with temperature adjustment function according to the season.

[0014] In the mask of the present invention, the central part of the inner fabric is The shape is made up of a bottom side disposed downward and a pair of inner sides extending upward from both sides of the bottom side, or a bottom side and a ceiling side disposed in the vertical direction and a pair of side sides disposed in the left-right direction, It is preferable that a cutout portion is provided for at least the wearer's nose to fit in, and that one of the openings of the pocket portion is formed in the portion of the inner fabric that is located at the cutout portion.

[0015] According to the above aspect, when wearing the mask, the wearer's nose is inserted into the notch and positioned on the back side of the outer fabric. Therefore, when air is drawn in, it is drawn in only through the outer fabric, which reduces ventilation resistance and makes it easier to draw in air.

[0016] In addition, pockets are formed on both the left and right sides of the cutout, and one of the openings of the pocket is formed in the part of the inner fabric that is located at the cutout. Therefore, the breath exhaled from the wearer's nose flows into the pocket through the opening located at the cutout and is exhausted from the opening located on the outside of the mask of each pocket, allowing the breath to be exhausted smoothly.

[0017] In the mask of the present invention, a protrusion having a three-dimensional shape that protrudes outward when worn is provided in the center of the outer fabric, and it is preferable that the inside of the protrusion forms a three-dimensional space that can accommodate at least the wearer's nose through the cutout.

[0018] According to the above aspect, a protrusion having a three-dimensional shape that protrudes outward when worn is provided in the center of the outer fabric, and the inside of this protrusion forms a three-dimensional space into which the wearer's nose fits. This makes it easier for the breath exhaled from the nose to escape from the three-dimensional space inside the protrusion into the left and right pockets, more effectively preventing the breath from becoming trapped inside the mask and effectively reducing the feeling of heat.

[0019] In the mask of the present invention, it is preferable that a sheet-like material containing a cooling material or a heat-generating material is detachably housed in the pocket portion.

[0020] According to the above aspect, by storing a sheet-like material containing a cooling material or a heat-generating material in the pocket portion, it is possible to provide a cooling effect in summer and a heat-retaining effect in winter, thereby further improving the comfort of wearing the mask. [Effects of the Invention]

[0021] According to the present invention, the wearer's breath enters each pocket through an opening provided at the inner end of each pocket and is then exhausted to the outside of the mask through an opening provided at the outer end of each pocket, which makes it difficult for the breath to become trapped inside the mask and makes it less likely for the mask to become stuffy.In addition, since the pockets are formed integrally with the mask body using the outer and inner fabrics, it is possible to obtain a mask that can reliably exhaust the wearer's breath with a simple structure.

[Figure 7] FIG. 10 shows a third embodiment of the mask according to the present invention, and is an explanatory view seen from the rear side. DETAILED DESCRIPTION OF THE INVENTION

[0023] (First embodiment of the mask) A first embodiment of a mask according to the present invention will be described below with reference to FIGS.

[0024] As shown in Figures 1 and 2, this mask 10 has an outer fabric 30 and an inner fabric 40 partially placed inside it, and is equipped with a mask body 20 that covers the nose 3 and mouth 5 of the wearer 1, and ear loops 25, 25 that are looped and connected to both sides of the mask body 20 and can be hooked onto the ears 7 of the wearer 1.

[0025] The ear hook 25 is made of a string-like material that has elasticity and can be stretched and contracted. However, the ear hook 25 may also be a string that does not have elasticity. The ear hook 25 may also be provided with an adjuster that allows the length to be adjusted.

[0026] The inner fabric 40 is attached to the back side of the outer fabric 30, avoiding the area where at least the nose 3 of the wearer 1 will fit, and pocket parts 50 surrounded by the outer fabric 30 and the inner fabric 40 are formed on both sides of the area where at least the nose 3 of the wearer 1 will fit.

[0027] Furthermore, openings 51, 53 that are not blocked by the outer fabric 30 and the inner fabric 40 are provided at the left and right ends of each pocket portion 50. The opening 51 is located at the left and right end of the mask 10 (hereinafter also referred to as the "outer end"), and the opening 53 is located at the end of the mask 10 that is closer to the center in the left and right direction (hereinafter also referred to as the "inner end").

[0028] 2, in this embodiment, a cutout 45 is provided in the center of the inner fabric 40, into which at least the nose 3 of the wearer 1 fits. The pair of pockets 50, 50 described above are arranged on both the left and right sides of this cutout 45. Furthermore, one of the openings 51, 53 of the pocket 50 is formed in the part of the inner fabric 40 that is located at the cutout 45.

[0029] In this embodiment, each pocket portion 50 is formed so that the opening 53 on the inner end side is positioned in the notch 45 of the inner fabric 40 .

[0030] 4, a three-dimensional protrusion 35 that protrudes outward when worn is provided in the center of the outer fabric 30. That is, the mask 10 in this embodiment is a so-called three-dimensional mask that has a three-dimensional protrusion 35 that covers the nose 3 and mouth 5 of the wearer 1. In this embodiment, the protrusion 35 is formed by a fold 36 formed by overlapping and welding the outer fabric 30, as will be described later.

[0031] 3, the outer fabric 30 has a shape that extends elongatedly in the left-right direction. In this embodiment, the outer fabric 30 is widest at the center in the longitudinal direction (the mask 10 is tallest in the vertical direction) and gradually narrows toward both ends in the longitudinal direction. The upper side of the outer fabric 30 is the upper side 31, the lower side is the lower side 32, and the left-right sides are the outer sides 33, 33.

[0032] On the other hand, the inner fabric 40 in this embodiment has a shape that extends long in the left-right direction to fit the outer fabric 30, and is widest at the center in the longitudinal direction and gradually narrows toward both ends in the longitudinal direction. The upper side of the inner fabric 40 forms an upper side 41, the lower side forms a lower side 42, and the left-right sides form outer sides 43, 43.

[0033] The cutout 45 is formed in the longitudinal center of the inner fabric 40. As shown in Fig. 3, the cutout 45 in this embodiment is generally U-shaped, opening both in the front-to-rear direction of the mask and at the top. More specifically, the cutout 45 is located in the longitudinal center of the inner fabric 40 and comprises a base 45a located above the bottom edge 42, inner edges 45b, 45b extending upward at a constant width from both sides of the base 45a, and an opening 45c located above the mask and communicating with the outside. The nose 3 and mouth 5 of the wearer 1 are adapted to fit into the cutout 45.

[0034] As shown in Fig. 3, the width H of the cutout 45 (the distance between the inner sides 45b, 45b) is preferably 2 to 20 cm, and more preferably 3 to 15 cm. Furthermore, as shown in Fig. 3, the height T of the cutout 45 (the distance from the bottom side 45a to the upper end) is preferably 2 to 20 cm, and more preferably 3 to 15 cm, and most preferably 3 to 7 cm.

[0035] Returning to the explanation of the outer fabric 30, the outer fabric 30 of this embodiment has a fold 36 formed in the longitudinal center by overlapping and welding the outer fabric 30, and the protrusion 35 having a three-dimensional shape that protrudes outward when worn is formed through this fold 36. In addition, the inside of the protrusion 35 provided on the outer fabric 30 forms a three-dimensional space that can accommodate at least the nose 3 of the wearer 1 through a cutout 45 formed in the inner fabric 40 (see FIG. 4).

[0036] The pair of left and right pocket portions 50, 50 are formed as follows.

[0037] That is, the upper edge 31 of the outer fabric 30 is abutted against the upper edge 41 of the inner fabric 40 at portions located on both the left and right sides of the cutout 45, and the lower edge 42 of the inner fabric 40 is abutted against the lower edge 32 of the outer fabric 30, and each abutting portion is covered with the edging 27. Then, the outer fabric 30 and the inner fabric 40 are joined together via the edging 27 by a joining method such as sewing or laminating (thermal welding, ultrasonic welding, bonding with an adhesive, etc.), thereby joining the upper and lower edges of the outer fabric 30 and the inner fabric 40, respectively, to form the mask body 20 as shown in Figures 1 and 2.

[0038] In this case, although the upper edge 41 and lower edge 42 of the inner fabric 40 are joined to the outer fabric 30, the two outer edges 43, 43 of the inner fabric 40 are not joined to the outer fabric 30, and furthermore, the inner edges 45b, 45b of the cutout portion 45 formed in the inner fabric 40 are also not joined to the outer fabric 30.

[0039] As a result, a pair of pockets 50, 50 are formed on the back side of the outer fabric 30, on both the left and right sides thereof via the notch 45 formed in the center of the inner fabric 40.

[0040] Furthermore, an opening 51 is formed at the outer end of each pocket 50 (the end of each pocket 50 located on the outside of the mask) surrounded by the outer fabric 30 and the outer edge 43 of the inner fabric 40 that is not joined to the outer fabric 30. Furthermore, a side opening 53 is formed at the inner end of each pocket 50 (the end of each pocket 50 located on the inside of the mask) surrounded by the outer fabric 30 and the inner edge 45b of the cutout portion 45 of the inner fabric 40 that is not joined to the outer fabric 30.

[0041] Therefore, each pocket 50 has a generally tunnel-like shape with openings 51, 53 at both left and right ends. The openings 51, 53 communicate with the internal space of each pocket 50. Furthermore, the opening 53 located at the inner end of the pocket 50 communicates with the cutout 45, and through the cutout 45, also communicates with the three-dimensional space inside the protrusion 35.

[0042] As a result of providing the pocket portion 50 as described above, as shown in Figure 5, the exhaled breath of the wearer 1 generated within the three-dimensional space inside the protrusion 35 passes through the cutout portion 45 and the opening 53, flows into the pocket portion 50, and is then exhausted from the opening 51 located at the outer end of the pocket portion 50.

[0043] The material for the outer fabric 30 having the above-described configuration may be, for example, a woven or knitted fabric or nonwoven fabric made of polyester fiber, polyamide fiber such as nylon, polyethylene fiber, acrylic fiber, polypropylene fiber, polyvinyl alcohol fiber, polyurethane fiber, regenerated fiber such as rayon or lyocell, acetate fiber (cellulose acetate), polylactic acid fiber, or the like.

[0044] Furthermore, the woven fabric, knitted fabric, or nonwoven fabric made from the above materials may be a single layer (one layer) or a multilayer made by laminating multiple layers, and further, woven fabrics, knitted fabrics, and nonwoven fabrics made from the above materials may be appropriately combined to form a multilayer structure.

[0045] The weight of the outer fabric 30 is 50 to 500 g / m 2 It is preferable that the thickness is 70 to 450 g / m 2 It is more preferable that:

[0046] On the other hand, the material for the inner fabric 40 may be, for example, a woven or knitted fabric made of polyester fiber, polyamide fiber such as nylon, polyethylene fiber, acrylic fiber, polypropylene fiber, polyvinyl alcohol fiber, polyurethane fiber, regenerated fiber such as rayon or lyocell, acetate fiber (cellulose acetate), polylactic acid fiber, etc.

[0047] Furthermore, it is preferable that the fibers used in the inner fabric 40 are long fibers rather than short fibers. This is because long fibers are less likely to pill (pill) even when the mask 10 is worn for an extended period of time (short fibers are prone to pilling after extended use).

[0048] Furthermore, the material used for the inner fabric 40 is preferably a woven fabric made of long fibers of polyamide such as nylon, or a woven fabric made of long fibers of polyester.

[0049] The weight of the inner fabric 40 is 30 to 250 g / m 2 It is preferable that the density is 50 to 200 g / m 2 More preferably, it is 100 to 190 g / m 2 It is most preferable that:

[0050] As shown in FIG. 3, each pocket 50 is adapted to detachably house a sheet-like material 60 containing a cooling material or a heat-generating material.

[0051] The sheet-like material 60 is preferably smaller than the openings 51, 53 so that it can be accommodated in the pocket portion 50 through the openings 51, 53. As shown in Fig. 3, the sheet-like material 60 in this embodiment is a thin, rectangular sheet. The thickness of the sheet-like material 60 is preferably 0.1 to 5 mm.

[0052] Furthermore, when the sheet-like material 60 contains a cooling sensation material, the sheet-like material 60 is preferably a so-called gel sheet consisting of a gel core layer to which a gel containing the cooling sensation material is applied and a thin film coating layer laminated on the gel core layer.

[0053] The gel has a three-dimensional network structure that traps a large amount of moisture, allowing for rapid heat conduction, and its high specific heat capacity allows it to give the wearer a refreshing feeling.

[0054] Furthermore, the gel is preferably selected from natural polymers (e.g., starches, celluloses, pectin, agar, collagen, hyaluronic acid, amino acids, alginic acid, chitosan, etc.) and synthetic polymers (e.g., polyvinyl alcohols, polypropylene salts, polyoxyethylenes, polyacrylamides, polyurethanes, and derivatives thereof, etc.).

[0055] Furthermore, adding a cooling aid such as mint or xylitol to the gel is preferable because it can further enhance the cooling sensation. It is also preferable to add a phase transition material to the gel. Microcapsules containing a phase transition substance are used as the phase transition material. In this case, when the temperature outside the mask rises, the phase transition material absorbs a large amount of heat and undergoes a phase transition, maintaining a constant temperature and extending the duration of the cooling sensation.

[0056] The thin film coating layer laminated on the gel core layer prevents evaporation of water from the gel, thereby extending the duration of the cooling sensation. Such a thin film coating layer is made of, for example, a polyurethane film (PU film), a thermoplastic polyurethane film (TPU film), a polytetrafluoroethylene film (PTFE film), etc., and it is preferable to use a film that is waterproof and breathable.

[0057] The thickness of this thin film coating layer is preferably 0.01 to 0.5 mm, which maintains waterproofness and prevents stains, while minimizing the effect on the conductivity of the cooling sensation.

[0058] On the other hand, when the sheet-like material 60 contains a heat-generating material, the sheet-like material 60 is preferably a heat-generating sheet containing iron powder and carbon powder.

[0059] The shapes and structures of the mask body, outer fabric, inner fabric, etc. described above are not limited to the above-described embodiments, and may be, for example, a substantially rectangular shape, a substantially elliptical shape with the long axis positioned horizontally, a substantially oval shape, etc. The outer fabric may not have a protrusion. Furthermore, the inner fabric may have a structure without a notch.

[0060] In addition, although the cutout portion formed in the inner fabric is generally U-shaped in this embodiment, it may be generally V-shaped, or a slit-like portion extending at a constant width from the lower edge of the mask to the upper edge, or may be a hole-like cutout such as a round hole, an oval hole, or a rectangular hole, as long as it allows at least the nose 3 of the wearer 1 to be inserted. Furthermore, the shape and structure of the pocket portion made of the outer fabric and the inner fabric are not limited to the above-mentioned aspects, and it is sufficient if it allows at least the exhaled breath of the wearer 1 to be exhausted to the outside of the mask.

[0061] (Action and effect) Next, the effects of the mask 10 having the above configuration will be described.

[0062] When putting on the mask 10, the wearer 1 faces the face with the inner fabric 40 facing the face, aligns the nose 3 and mouth 5 with the cutouts 45, places the mask body 20 on the face, and hooks the pair of ear loops 25, 25 onto the ears 7, 7, allowing the wearer 1 to wear the mask 10 as shown in Figure 1.

[0063] As shown in FIG. 5, in this mask 10, the wearer's 1 exhaled air enters each pocket portion 50 through openings 53 provided at the inner end of each pocket portion 50, and is then exhausted to the outside of the mask through openings 51 provided at the outer end of each pocket portion 50, thereby preventing the exhaled air from building up inside the mask 10 and making it less likely to become stuffy.

[0064] Furthermore, each pocket portion 50 is formed integrally with the mask body 20 using the outer fabric 30 and the inner fabric 40, so it is possible to obtain a mask 10 that has a simple structure and can reliably exhaust the breath of the wearer 1. Furthermore, there is no risk of the pocket portion 50 falling off the mask body 20, so the breath of the wearer 1 can be reliably exhausted.

[0065] Furthermore, since the exhaled air is discharged to the outside of the mask through the pair of pockets 50, 50, it is less likely that the exhaled air will come into contact with the face of the wearer 1 and become sticky. Also, since the exhaled air is discharged to the sides of the mask through the openings 51, 51 of the pair of pockets 50, 50, if the wearer 1 is wearing glasses, the glasses are less likely to fog up.

[0066] Furthermore, when the wearer 1 puts on the mask 10, the nose 3 of the wearer 1 is inserted into the cutout 45 and positioned on the back side of the outer fabric 30 (see FIG. 4). Therefore, when air is drawn in, the air is drawn in only through the outer fabric 30, which reduces ventilation resistance and makes it easier to draw in air.

[0067] In addition, pocket portions 50 are formed on both the left and right sides of the cutout portion 45, and one of the openings 51, 53 of the pocket portion 50 is formed in the portion of the inner fabric 40 located at the cutout portion 45 (here, the opening 53 located at the inner end of each pocket portion 50 is formed to be located at the cutout portion 45).

[0068] Therefore, as shown in Figure 5, the exhaled air exhaled from the nose 3 of the wearer 1 flows into the pocket portion 50 through the opening 53 located in the cutout portion 45 and is exhausted from the opening 51 located on the outside of the mask of each pocket portion 50, allowing the exhaled air to be exhausted smoothly.

[0069] 4, a protruding portion 35 having a three-dimensional shape that protrudes outward when worn is provided in the center of the outer fabric 30, and the inside of this protruding portion forms a three-dimensional space that fits the nose 3 of the wearer 1. As a result, the breath exhaled from the nose 3 can easily escape from the three-dimensional space inside the protruding portion 35 to the left and right pocket portions 50, 50, more effectively preventing the breath from being trapped inside the mask 10 and effectively reducing the feeling of being overheated.

[0070] Furthermore, a sheet-like material 60 containing a cooling material or a heat-generating material is removably housed in each pocket portion 50. That is, by housing the sheet-like material 60 containing a cooling material or a heat-generating material in the pocket portion 50, a cooling effect can be achieved in summer and a heat-retaining effect can be achieved in winter, thereby further improving the wearing comfort of the mask 10.

[0071] (Second embodiment of the mask) A second embodiment of the mask according to the present invention will be described below with reference to Fig. 6. Note that parts that are substantially the same as those in the previous embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0072] In this mask 10A, the shape of the notch 46 is different from the notch 45 of the mask 10 of the previous embodiment.

[0073] That is, the cutout portion 46 in this embodiment is a substantially rectangular hole having a bottom side 46a and a top side 46b arranged substantially parallel to each other in the vertical direction of the mask 10A, and both side sides 46c, 46c arranged substantially parallel to each other in the left-right direction of the mask 10A. Furthermore, none of the bottom side 46a, the top side 46b, and both side sides 46c, 46c that form the cutout portion 46 are joined to the outer fabric 30.

[0074] The mask 10A having the above structure can also achieve the same effects as the mask 10 of the above embodiment.

[0075] (Third embodiment of the mask) A third embodiment of the mask according to the present invention will be described below with reference to Fig. 7. Note that parts that are substantially the same as those in the previous embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0076] This mask 10B has an inner fabric 40B whose structure is different from that of the inner fabric 40 of the above embodiment.

[0077] That is, the inner fabric 40B in this embodiment is a plate-like piece having a substantially rectangular shape, and is arranged on both the left and right sides of the back surface of the outer fabric 30. Each of the pair of inner fabric pieces 40B, 40B has a bottom side 47 and a top side 48 joined to the outer fabric 30, while both side sides 49, 49 are not joined to the outer fabric 30. As a result, an opening 51 is provided at the outer end of each pocket portion 50B, and an opening 53 is provided at the inner end of each pocket portion 50B.

[0078] In addition, a nose fixing part 65 made of wire or the like is provided at the center of the longitudinal direction of the mask 10 and above the mask, which makes it possible to prevent the mask from shifting position when worn.

[0079] The mask 10B having the above structure can also provide the same effects as the masks 10 and 10A of the above embodiments.

[0080] It should be noted that the present invention is not limited to the above-described embodiment, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention. [Example]

[0081] (1) Example 1 A mask of Example 1 similar to the mask shown in FIGS. 1 to 5 was manufactured.

[0082] The outer fabric 30 has a three-layer structure. The outer layer is made of nylon and polyurethane and has a basis weight of 150 g / m 2 The middle layer is a polypropylene meltblown nonwoven fabric with a basis weight of 25 g / m 2 The back layer is made of 100% polyethylene and has a cooling effect, with a basis weight of 180 g / m 2 These three layers are stacked and ultrasonically fused (ultrasonic quilted) to bond them together, and then the outer periphery is cut to the desired shape.

[0083] The inner fabric 40 is made of 100% polyethylene and has a basis weight of 150 g / m 2 The outer periphery of the inner fabric 40 is cut to a shape that fits the outer fabric 30, and the center of the inner fabric 40 is cut to form a notch 45.

[0084] The inner fabric 40 is placed behind the outer fabric 30, and both fabrics 30, 40 are folded in half at the center in the longitudinal direction. Then, ultrasonic welding is performed on the center of the overlapping outer fabric 30 to form a fold 36. At the same time, unnecessary portions of both fabrics 30, 40 are cut away. The outer fabric 30 is then unfolded via the fold 36 to form a three-dimensional protrusion 35.

[0085] Thereafter, the corresponding sides of the outer fabric 30 and the inner fabric 40 are brought together and the predetermined joining portions are sewn together via the edging 27 to form a pair of pockets 50, 50. Furthermore, the ear loops 25 are connected to each side of the mask body 20.

[0086] Furthermore, a sheet-like material 60 containing a cooling sensation material was prepared by laminating a thin film covering layer made of a thermoplastic polyurethane film onto a gel core layer containing 10% phase transition material. The thickness of this sheet-like material 60 was 2 mm. By storing this sheet-like material 60 in each pocket portion 50, a mask of Example 1 similar to the mask shown in Figures 1 to 5 was produced.

[0087] (a) Cool-to-touch test of Example 1 For Example 1, the cool feeling to the touch in the pocket portion 50 containing the sheet material 60 and in the portion without the sheet material 60 were measured under the condition of 20° C. The results are shown in Table 1 below. [Table 1]

[0088] As a result, it was confirmed that the cool feeling to the touch in the pocket portion 50 containing the sheet-like material 60 was greater than the cool feeling to the touch in the portion without the sheet-like material 60.

[0089] (b) Test of sustained cooling sensation in Example 1 For Example 1, the duration of the cooling sensation in the pocket portion 50 containing the sheet material 60 and the duration of the cooling sensation in the portion without the sheet material 60 were measured. The test was performed by placing the mask on a hot plate tilted to 45°C, and measuring the temperature (at the start) without heating the hot plate, and the temperature 10 minutes after heating the hot plate to a predetermined temperature. The results are shown in Table 2 below. [Table 2]

[0090] As a result, it was confirmed that the cool sensation lasting longer in the pocket portion 50 in which the sheet-like material 60 was stored than in the portion in which the sheet-like material 60 was not stored.

[0091] (2) Example 2 6 was manufactured by the same manufacturing method as in Example 1. The sheet-like material 60 was not contained in the pocket portion 50.

[0092] The outer fabric 30 has an outer layer of 100% polyester, a middle layer of 100% polypropylene Meldblown, and a back layer of 50% cotton and 50% nylon woven fabric. The weight of the outer fabric 30 is 300 g / m 2 is.

[0093] The inner fabric 40 is made of 100% polyethylene and has a basis weight of 180 g / m2. The notch 46, which is roughly a square hole, is formed in the center of the inner fabric 40 and has a width H of 5 mm and a height T of 5 mm.

[0094] Thereafter, the corresponding sides of the outer fabric 30 and the inner fabric 40 were abutted together, and the predetermined joints were sewn together via the edging 27, thereby producing a mask of Example 2 similar to the mask shown in Figure 6.

[0095] (3) Example 3 A mask of Example 3 similar to the mask shown in FIG. 7 was manufactured.

[0096] The outer fabric 30 has a four-layer structure. The outermost layer is made of 100% polyester with an antiviral finish and has a basis weight of 200 g / m 2 The inner layer is made of polytetrafluoroethylene (PTFE) with a basis weight of 15 g / m 2 The inner layer is a polypropylene spunbond nonwoven fabric with a basis weight of 15 g / m 2 The innermost layer is a far-infrared polyester knit with a weight of 200 g / m 2These four layers are stacked and ultrasonically fused (ultrasonic quilted) to bond them together, and then the outer periphery is cut to the desired shape.

[0097] The inner fabric 40 is made of 100% polypropylene and has a basis weight of 140 g / m 2 This was cut into a rectangular shape and placed on both sides of the back side of the outer fabric 30, and the top and bottom sides were sewn to the outer fabric 30 to create a pair of pockets 50B, 50B.

[0098] Furthermore, a sheet-like material 60, which is a warming sheet containing a heat-generating material having iron powder and carboxymethyl cellulose, was placed in each pocket portion 50B to produce Example 3, which is similar to the mask shown in FIG.

[0099] (a) Warmth Test of Example 3 For the mask of Example 3, in which the warming sheet material 60 was placed in each pocket 50B, the temperature change on the mask surface over a predetermined time period was measured. The test time was 30 minutes, and measurements were taken every 5 minutes. The results are shown in Table 3 below. [Table 3]

[0100] As a result, it was confirmed that the temperature of the mask surface reached its highest after 15 minutes and then gradually decreased. [Explanation of symbols]
