Description of the Related Art Conventional non-woven masks are formed by three-dimensionally forming a non-woven fabric sheet into a substantially bowl shape (hereinafter referred to as a three-dimensionally formed mask) or by half-folding one to several fiber sheets by sewing. (Called a flat mask). These are good in terms of dust collection efficiency and expiration / inspiration resistance,
It functions sufficiently as a mask.

・湿度は外気の温度・湿度と比較すると非常に高いた
め、マスク内は蒸れた状態となり易い。[0003] The temperature of exhaled air from the human lung is about 35 ° C, and the humidity is about 85%. Since the temperature and humidity of the exhaled air are much higher than the temperature and humidity of the outside air, the inside of the mask is likely to be stuffy.

ではなかった。[0004] Among the prior arts, the former three-dimensional molded mask has a structure in which it has a mouth and a nose portion and a space and is in close contact with the face, and has an advantage that breathing is easy. However, since the exhaled air is trapped in the space, the space becomes hot and humid and becomes humid, and the humid air hits the face and gives the user discomfort. Further, the latter flat mask has a structure in which the mouth and nose are directly in contact with each other, and the expired gas directly hits the mask, so that the mask (fiber sheet) itself becomes high temperature and high humidity. As a result, the humid or wet mask comes into contact with the face, causing a problem of giving the user discomfort. Thus, prior art masks have not been satisfactory in terms of comfort during use.

No. 7,883, No. 7,883, the upper layer having heat insulating property and moisture permeability suppressing property and the lower layer having moisture absorbing property are constituted by a composite sheet in which the anti-stuffing device is constituted, so that the heat and moisture of the expiration are formed on the upper layer. With the function of blocking
The function of absorbing moisture was imparted to the lower layer to eliminate the stuffiness when using the mask. However, even if the anti-steaming device is configured by such means, the upper layer lacks air permeability, so there is no escape place for moisture absorbed by the lower layer,
When used for a long time, it was not possible to completely eliminate the stickiness and stuffiness of the face.

クを長時間心地良く使用可能にすることを課題とする。SUMMARY OF THE INVENTION The present invention is intended to prevent the direct action of exhaled air on the face and to release the adsorbed moisture of the lower layer and the moisture caused by perspiration from the face through the upper layer to make the face sticky and stuffy. It is an object to eliminate various feelings and to make various masks usable comfortably for a long time.

とを接合した複合シートで構成して成る。SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a mask anti-humidity device capable of covering at least a portion corresponding to a nose and a mouth so as to cover a substantially lower half of a face. The above-mentioned anti-stuffing device is constituted by a composite sheet in which an upper layer of a fine porous sheet having air permeability and a lower layer of a moisture-absorbing sheet are joined.

されるから、顔面のベトツキ感や蒸れ感が解消される。According to this means, heat and moisture due to exhalation are blocked by the upper layer, while moisture due to sweat from the face is adsorbed on one surface of the lower layer and diffused into the lower layer, and from the other surface of the lower layer. Since it passes through the upper layer and is released into the inside of the mask, the feeling of stickiness and stuffiness on the face is eliminated.

蒸れ感が生じる傾向になる。In the present invention, the microporous sheet preferably has a ventilation resistance of 1 kpa · s / m or more. In this way, at the time of inhalation in which the inside of the mask has a negative pressure, fresh outside air enters the inside of the mask and, at the same time, air containing moisture on the face passes through the upper layer and is discharged into the inside of the mask. In the case of exhalation in which the inside of the mask becomes high pressure, the airflow resistance of the upper layer and 30 pa · s / m to 50 pa
-Since there is a very large difference between the air flow resistance of a general mask which is s / m, this air flow resistance difference
Most of the exhaled air escapes from the mask and no exhalation is felt on the face. When the airflow resistance of the microporous sheet is less than 1 kpa · s / m, the airflow resistance difference decreases, and a large amount of expiration passes through the upper layer and touches the face,
A feeling of stuffiness tends to occur.

By using the film sheet or the fiber sheet having the above-mentioned properties, a suitable breath-blocking property and a good moisture-releasing property can be obtained.

る。なお、図中１ｃは熱融着部である。In the embodiment shown in FIGS. 1 and 2, the composite sheet 1 used for the anti-stuffing device M is obtained by embossing an upper layer 1a of a fine porous sheet having air permeability and a lower layer 1b of a moisture absorbing sheet. It is made by heat bonding. And
The composite sheet 1 is punched into a predetermined shape having a size large enough to cover substantially the lower half of the face, and a nose opening 2
The mouth opening 3 is provided, and rubber straps are attached to both sides to form the ear hooks 4, thereby forming a desired stuffiness prevention device M. In the figure, reference numeral 1c denotes a heat-sealed portion.

In addition, the composite sheet is formed into a three-dimensional shape along a substantially lower half of the face by omitting an ear hook part by a predetermined method, or a stuffing preventer is attached to the inside of conventionally known various three-dimensional molding masks. Therefore, it is also possible to attach and use them integrally.

It is preferable to form a three-dimensional shape by cutting at least a part of the portion into a substantially C-shape, and then joining the edges of opposing sides of the notch together.

ある。In this case, as the shape of the stuffiness preventing device M, a nose-to-mouth opening which is largely open including the boundary between the nose and the mouth is provided instead of the nose opening 2 and the mouth opening 3. Is also possible. In addition, instead of the rubber cord, the ear hook portion 4 can be formed by punching out the composite sheet in a shape in which both sides are extended and opening a portion corresponding to both ears.

感じることがより一層防止することができる。According to the present invention, even when various masks are used for a long period of time, the upper layer has an appropriate function of blocking breath and releasing moisture and the lower layer exhibits functions of absorbing moisture. This makes it possible to comfortably use various masks without causing a feeling of stuffiness or stickiness, and is particularly effective for use in a hot and humid summer. Further, when the upper layer has a ventilation resistance of 1 kpa · s / m or more, due to a difference in ventilation resistance from a conventionally known mask, almost all of the exhaled air escapes from the mask, and it is possible to further prevent the exhalation from being felt on the face. .
