It arranges at the central part of each horizontal direction H. Here, the central portion of the first adhesive portion 50 and the second upper surface contact portion 40 is a position where the first adhesive portion 50 and the second upper surface contact portion 40 contact the user's nose (not shown), and does not mean that it must be strictly central ( See Figure 3A, B).

In addition, the first bonding portion 50 bonding the upper surface contact portion 30 and the second upper surface contact portion 40 is the center of the first adhesive portion 50 and the second upper surface contact portion 40 in the left-right direction H. As described above, since the upper surface contact portion 30 and the second upper surface contact portion 40 have a bag-like shape when arranged in the left side portion, the left side portion 50a and the right side portion 50b are formed by the first adhesive portion 50. It will have a bag-like shape. Therefore, as described later, although the left side 50a and the right side 50b expand when used by the user, the first adhesive unit 50 abuts on the user's nose without expanding. Therefore, the side gap of the user's nose which is not shown in figure can be closed by bulging left side part 50a and right side part 50b. In addition, it is preferable to weld the 1st adhesion part 50 by six circular points. When welded in this manner, the non-woven fabric is hard to harden and the wearing comfort is good. Further, by welding some of the six points, it is possible to absorb some positional deviation of the first bonding unit 50.

Next, the mask 10B in the third embodiment will be described.

Close contact with the nose by touching. In addition, since the second upper surface contact portion 40 has a bag-like shape as described above on both sides of the user's nose, the user's exhalation flows into the bag-like portion, 2 The upper surface contact portion 40 is in close contact with the nose. Therefore, the portion between the user's nose and cheek is in close contact with the second upper surface contact portion 40, so that the gap with the mask 10 is closed, and there is a possibility that the user's exhalation may flow out. Can be reduced. Therefore, when using glasses, it is possible to prevent fogging of the glasses.

Next, the method of mounting the mask 10A in the second embodiment to the user (not shown) is the same as that of the mask 10 in the first embodiment. In order to attach the mask 10A to the user (not shown), the first adhesive portion 50 for adhering the upper surface contact portion 30 disposed on the back surface of the mask main body portion 20 and the second upper surface contact portion 40 Contact the nose. Therefore, the second upper surface contact portion 40 can be in close contact with the slope of the user's nose, and on both sides of the user's nose, the left side 50a and the right side 50b have a bag shape. When the user's exhaled breath flows in, the left side 50a and the right side 50b come in close contact with both sides of the user's nose. Therefore, the gap between the user's nose and cheek and the mask is blocked by the expanded left side 50a and the right side 50b, and the possibility that the user's exhalation may flow out (See FIGS. 8 and 9). Therefore, when using glasses, it is possible to prevent fogging of the glasses.

Next, the method of mounting the mask 10B in the third embodiment to a user (not shown) is the same as that of the mask 10 in the first embodiment. In order to wear the mask 10B to the user (not shown), the second upper surface contact portion 40 disposed on the back surface of the mask main body portion 20 abuts on the user's nose. Therefore, the second upper surface contact portion 40 can be in close contact with the slope of the user's nose, and on both sides of the user's nose, the left adhesive portion 51a and the right adhesive portion 51b, Because the portion 51 between them has a bag-like shape, the user's exhalation flows into the portion 51, and the portion 51 between the left adhesive portion 51a and the right adhesive portion 51b of the user's nose Close contact with both sides. Therefore, the gap between the user's nose and cheek and the mask is blocked by the portion 51 between the expanded left adhesive portion 51a and the right adhesive portion 51b, and the user's exhalation flows out Possibility to be reduced as much as possible (see FIGS. 10 and 11). Therefore, when using glasses, it is possible to prevent fogging of the glasses.

Next, the method of mounting the mask 10C in the fourth embodiment to a user (not shown) is the same as that of the mask 10 in the first embodiment. In order to attach the mask 10C to the user (not shown), the first adhesive portion 50 for adhering the upper surface contact portion 30 disposed on the back surface of the mask main body portion 20 and the second upper surface contact portion 40 Contact the nose. Therefore, the portion 52a between the first bonding portion 50 and the left bonding portion 51a and the portion 52b between the first bonding portion 50 and the right bonding portion 51b have a bag shape, respectively. Inflow of the user's exhalation into the portion 52a and the portion 52b brings the portion 52a and the portion 52b into close contact with both sides of the user's nose. Therefore, the gap between the user's nose and cheeks and the mask will be blocked by the bulging portion 52a and the portion 52b, thereby reducing the possibility of the user's exhalation flowing out as much as possible. (See Figures 10 and 11). Therefore, when using glasses, it is possible to prevent fogging of the glasses.

The mask 10, the mask 10A, the mask 10B, and the mask 10C have a buffer portion 75 in the form of a sponge, and by arranging the nose fitter 70, the shape of the mask 10 or the like is used. By following the shape of the person's nose and preventing exhalation leakage as much as possible, it is possible to further prevent fogging of the glasses.

Further, as described above, the mask main body 20, the second upper surface contact portion 40, and the upper surface contact portion 30 can be configured by laminating two or three non-woven fabrics, respectively.

Furthermore, one non-woven fabric can be further laminated on the second upper surface contact portion 40 and the upper surface contact portion 30, respectively. That is, as described later, the other second upper surface contact portion 40 'and the other upper surface contact portion 30' can be configured by laminating five non-woven fabrics (see FIGS. 14A and 14B). .

Specifically, not only the mask 10 but also the mask 10A, the mask 10B, and the upper surface contact portion 30 in the mask 10C, the first non-woven fabric 30a, the second non-woven fabric 30b, the third non-woven fabric 30c, and the fourth non-woven fabric 30d It can laminate by four sheets of nonwoven fabric of, and can be constituted. Further, also in the second upper surface contact portion 40, four non-woven fabrics of the first upper surface non-woven fabric 40a, the second upper surface non-woven fabric 40b, the third upper surface non-woven fabric 40c, and the fourth upper surface non-woven fabric 40d (See FIG. 14A). Although not illustrated, in the second upper surface contact portion 40, only the second upper surface non-woven fabric 40b is removed, and three sheets of the first upper surface non-woven fabric 40a, the third upper surface non-woven fabric 40c, and the fourth upper surface non-woven fabric 40d It is also preferable to constitute by laminating with a non-woven fabric. Further, in this case, the upper surface contact portion 30 may be configured by laminating four non-woven fabrics of the first non-woven fabric 30a, the second non-woven fabric 30b, the third non-woven fabric 30c, and the fourth non-woven fabric 30d. preferable.

In addition to the mask 10 ', the upper surface contact portion 30 of the mask 10A', the mask 10B 'and the mask 10C' further includes a first non-woven fabric 30a, a second non-woven fabric 30b, a third non-woven fabric 30c, and a fourth non-woven fabric 30a. It can be laminated and configured by five non-woven fabrics of non-woven fabric 30d and fifth non-woven fabric 30e. Furthermore, it is configured to be laminated by five non-woven fabrics of the first upper non-woven fabric 40a, the second upper non-woven fabric 40b, the third upper non-woven fabric 40c, the fourth upper non-woven fabric 40d, and the fifth upper non-woven fabric 40e. Yes (see FIG. 14B).

Furthermore, the second upper surface contact portion 40 and the upper surface contact portion 30 can be separately provided, or they can be provided as a series. That is, to provide as a series, the first non-woven fabric 30a and the first upper non-woven fabric 40a are made of one non-woven fabric, and the second non-woven fabric 30b and the second upper non-woven fabric 40b are one non-woven fabric The third non-woven fabric 30c and the third upper surface non-woven fabric 40c are composed of a single non-woven fabric, and the fourth non-woven fabric 30d and the fourth upper surface non-woven fabric 40d are composed of a single non-woven fabric By doing this, the second upper surface contact portion 40 and the upper surface contact portion 30 can be stacked by four non-woven fabrics. This applies not only to the mask 10 but also to the mask 10A, the mask 10B, and the mask 10C (see FIG. 14A).

Furthermore, as described above, not only the mask 10 ', but also the mask 10A', the mask 10B ', the other second upper surface contact portion 40' in the mask 10C ', and the other upper surface contact portion 30' A fifth non-woven fabric 30e and a fifth top non-woven fabric 40e, which are non-woven fabrics of the eyes, are provided. The difference between the mask 10, the mask 10A, the mask 10B, and the mask 10C is that the other upper surface contact portion 30 'has a fifth non-woven fabric 30e. Further, the other second upper surface contact portion 40 ′ further includes a fifth upper surface non-woven fabric 40 e. Therefore, since the other points are the same, the same reference numerals are given and the description thereof is omitted. In addition, by providing the fifth non-woven fabric 30e and the fifth upper surface non-woven fabric 40e as a series of the above-mentioned formed by a single non-woven fabric, a total of five non-woven fabrics can be laminated (see FIG. 14B). ). However, it goes without saying that they can be provided separately. Thus, the upper surface contact portion 30, the second upper surface contact portion 40, the other upper surface contact portion 30 ', and the other second upper surface contact portion 40' A sheet of non-woven fabric can be laminated.

As described above, the second upper surface contact portion 40 and the upper surface contact portion 30 are one more than the mask body 20, and the other upper surface contact portion 30 'and the other second upper surface contact portion 40' In this case, two or more non-woven fabrics of 4 sheets or 5 sheets, respectively, are laminated to change the thickness of the leaky nose portion and the other portions, whereby the exhalation from the nose portion becomes difficult to leak. In addition, even if a relatively hard nose fitter 70 is used, a thin cloth with a good touch can be used. In particular, in the case where the nose fitter 70 is made of aluminum, it is configured by laminating two or three non-woven fabrics, and when the upper surface contact portion 30 is formed, the upper surface contact portion 30 is formed. The thick non-woven fabric is used so that the nose fitter 70 does not break out, while four or five non-woven fabrics are laminated on the upper surface contact portion 30 or the other upper surface contact portion 30 ', respectively. By adopting a relatively thin non-woven fabric, the possibility of the nose fitter 70 breaking and popping out of the upper surface abutting portion 30 or the other upper surface abutting portion 30 'is reduced as much as possible. The texture of the user can be improved. Further, in the so-called basis weight of displaying the weight per 1 m ² in grams, the use of 30 percent thinner nonwoven, can be easily removed exhalation.

Moreover, about the mask main body 20, it can breathe favorably by laminating | stacking and comprising 2 sheets or 3 sheets of nonwoven fabrics. In this case, the mask main body 20 is preferably configured by laminating three non-woven fabrics. Specifically, for example, when three non-woven fabrics are laminated, the mask main body 20 should be laminated by the first main non-woven fabric 20a, the second main non-woven fabric 20b, and the third main non-woven fabric 20c. it can. This applies not only to the mask 10 but also to the
