Description

Mask {MASK}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a structure technique of a mask mounted on a wearer's face.

Conventionally, for example, the following Patent Document discloses a mask having a fibrous substance made of microporous hollow fibers containing menthol.

Japanese Patent Laid-Open No. S63-209666

Here, in order to increase the trapping property (for example, the bacterial droplet filtering efficiency (BFE)) of the mask, it is necessary to lower the air permeability of the outer nonwoven fabric sheet disposed on the outer side of the mask . On the other hand, if the breathability of the outer nonwoven fabric sheet is lowered, the wearer feels a breathing difficulty. For this reason, development of an outer nonwoven fabric sheet capable of ensuring both the collecting performance and the breathability of the mask at a high level is progressing. The present inventors have also studied the inner nonwoven fabric sheet disposed on the wearer side in parallel with the development of the outer nonwoven fabric sheet. As a result, the air permeability of the inner nonwoven fabric sheet is higher than the air permeability of the outer nonwoven fabric sheet, It is easy to reach the nasal mucosa of the nostril, and it is difficult to feel the breathing.

Accordingly, it is an object of the present invention to provide a novel technique capable of ensuring both the trapping property and the breathability of the mask at a high level.

The present invention includes a mask body portion covering at least the mouth and nose of the wearer. For reference, generally, a mounting member for mounting the mask main body is provided. As the mounting member, for example, a piercing portion for a wearer's ear, a headband portion for surrounding the wearer's head portion, and the like are used. The mask body portion has an inner nonwoven fabric sheet, an outer nonwoven fabric sheet, and a fragrance-containing nonwoven fabric sheet provided between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, and laminated so that the inner nonwoven fabric sheet is disposed on the wearer side when the mask is worn .

The fragrance-containing nonwoven fabric sheet contains microcapsules containing a perfume. As the microcapsule, a capsule which can be easily broken by applying an external force, such as tapping with the hand or rubbing with the hand, is used. As the fragrance, various fragrances can be used. For example, it is possible to use menthol which is said to be effective against sneezing, rhinorrhea, and nasal clogging due to rhinitis, allergies and the like.

The air permeability of the inner nonwoven fabric sheet is set higher than the air permeability of the outer nonwoven fabric sheet (the air permeation resistance is reduced). For reference, the air permeability of the outer nonwoven fabric sheet can be increased within a range in which the trapping property of the mask is not deteriorated.

In the present invention, since the air permeability of the inner nonwoven fabric sheet is set to be higher than the air permeability of the outer nonwoven fabric sheet, the fragrance generated by the destruction of the microcapsules contained in the fragrance-containing nonwoven fabric sheet is likely to reach the mucous membrane of the nostril of the wearer The wearer becomes less likely to feel the breathing.

In another aspect of the present invention, the outer nonwoven fabric sheet is composed of an electret nonwoven fabric sheet having an average fiber diameter of 1 to 3 占 퐉 and a basis weight of ² to 5 g / m2.

In this embodiment, it is possible to easily obtain a mask in which both the trapping property and the breathability of the mask are made high.

In another embodiment of the present invention, the frictional resistance between the inner nonwoven fabric sheet and the perfume containing nonwoven fabric sheet is smaller than the frictional resistance between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet. The frictional resistance can be changed, for example, by selecting a material contained in the inner nonwoven fabric sheet.

In this embodiment, when an external force is applied to the mask body portion by hand rubbing or the like, microcapsules present in the area of the inner nonwoven fabric sheet, among the microcapsules contained in the fragrance-containing nonwoven fabric sheet, are easily broken .

In another embodiment of the present invention, the fragrance-containing nonwoven fabric sheet is composed of a nonwoven fabric sheet and a microcapsule containing a perfume, which is applied to a region of the nonwoven fabric sheet facing the inner nonwoven fabric sheet.

In this embodiment, since the microcapsules are arranged in the area facing the inner nonwoven fabric sheet, the fragrance generated from the fragrance easily reaches the mucous membrane of the nostril of the wearer.

For reference, by combining the configuration of this embodiment and the above-described configuration in which the frictional resistance between the inner nonwoven fabric sheet and the perfume containing nonwoven fabric sheet is smaller than the frictional resistance between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, Occurs. That is, the microcapsule can be easily broken and the microcapsule can be disposed at a position where it is easily broken.

In another aspect of the present invention, the mask body portion has an upper bonding region and a lower bonding region in which an inner nonwoven fabric sheet, a fragrance-containing nonwoven fabric sheet, and an outer nonwoven fabric sheet are bonded. In the upper bonding region and the lower bonding region of the mask main body portion, the microcapsules are not contained in the perfume-containing nonwoven fabric.

In this embodiment, when the upper and lower bonding portions are formed, it is possible to prevent the microcapsules containing the fragrance from being inadvertently broken.

In another aspect of the present invention, the upper bonding region is defined by the upper folding back portion of the inner nonwoven fabric sheet folded back above the mask body portion. Further, the lower bonding region is defined by the lower folding portion bent backward from the lower side of the mask main body portion.

In this embodiment, the upper junction region and the lower junction region can be easily defined, and the operation of embedding (coating) the microcapsules containing the perfume into the fragrance-containing sheet can be easily performed.

In another aspect of the present invention, the mask body portion has a pressing area which is pressed by a nip roll during mask production. In the pressing region of the mask body portion, the microcapsules are not contained in the fragrance-containing nonwoven fabric.

In this mode, when the nip roll is pressed in the mask manufacturing process, it is possible to prevent the microcapsule containing the perfume from being inadvertently broken.

In another aspect of the present invention, the mask body portion has a right joint region where the right ear piece is joined by the right joint and a left joint region where the left ear piece is joined by the left joint. In the right side bonding region and the left side bonding region of the mask main body portion, microcapsules are not contained in the fragrance-containing nonwoven fabric sheet.

In this embodiment, when the right joint portion and the left joint portion are formed, it is possible to prevent the microcapsules containing the fragrance from being inadvertently broken.

In another aspect of the present invention, the mask body portion has a plurality of pleats extending in the left-right direction, so that the mask body portion has a three-dimensional shape when the mask is worn.

In this embodiment, when the mask is worn, the pleats at the center in the vertical direction are disposed at positions away from the wearer's face. Thus, the microcapsules containing the perfume can be prevented from coming into direct contact with the skin of the wearer.
