[First Embodiment]
(Composition of sanitary mask)
FIG. 1 is a schematic view of a sanitary mask according to an embodiment of the present invention. The configuration of the sanitary mask of the present invention will be described with reference to FIG.

As shown in FIG. 1, the sanitary mask 101 of the present invention includes a fiber portion 103 that covers a mouth and a nose having four corners. The fiber part 103 has a sufficient dust-proofing effect to prevent pollen and building material dust from passing through at the construction site, and is classified as DS1 to DS3 or DS1 to DS3 in the usage classification of the disposable dust-proof mask (Ministry of Labor Notification No. 88, 2000). DL1 to DL3 can be used. Furthermore, those having a poisonous effect from poisonous gas can also be used. As the material of the fiber portion 103, any known material such as polypropylene and polyester can be used.

The fiber portion 103 of the present invention may be configured to transmit infrared rays so as to be compatible with a face recognition system using infrared rays. Normally, if the face is covered with a mask, it becomes difficult to perform face recognition with a face recognition system, so it is necessary to remove the mask. Therefore, by using the fiber portion 103 that transmits infrared rays, it is possible to receive face recognition without removing the mask. As a result, complexity is reduced and hygiene can be maintained in good condition.

Since the fiber portion 103 is configured to transmit infrared rays, for example, the fiber portion 103 can be formed of black polyester fibers that do not transmit visible light but transmit infrared light. Further, it can be formed of a fiber or the like using a known infrared transmissive dye that does not transmit visible light but transmits infrared light.

In the present specification, when the sanitary mask 101 is worn on the face, the horizontal direction will be described as the horizontal direction and the vertical direction will be described as the vertical direction. The fiber portion 103 may be provided with a plurality of folds 105 extending in the lateral direction. The folds 105 are widened along the center of the face with many protrusions while reducing the length of the peripheral edge of the fiber portion 103 in the vertical direction. By deforming the shape of the fiber portion according to the face in this way, the fiber portion 103 can be fitted well to the face. Further, a sufficient space is provided between the mouth and the fiber portion 103.

Further, the sanitary mask 101 of the present invention includes an ear hook portion 107. By applying the ear hooks 107 connected to the four corners of the fiber portion to the left and right ears, the air entering from the gap between the fiber portion and the face can be reduced. Since the ear hook 107 has elasticity, the hygiene mask can fit many people. Moreover, even if the mouth is moved, it can be fitted depending on the situation.

(Fiber part covering the mouth and nose)
FIG. 2 is a schematic view of a fiber portion covering the mouth and nose according to the embodiment of the present invention. The fiber portion covering the mouth and nose of the present invention will be described with reference to FIG.

The fiber portion 103 covering the mouth and nose of the present invention has vertical cuts 109 at four corners. The notch 109 may be tilted not only in the vertical direction but also in the horizontal direction. The notch may extend in the approximate vertical direction, which is the approximate vertical direction of the face. The notch 109 is connected to the ear hook portion 107 at an arbitrary position over the length. More specifically, the ear hook portion 107 is connected to the fiber portion 103 by inserting the hook portion formed in the ear hook portion 107 into the notch 109.

Therefore, the longer the notch 109, the easier it is to adjust to the face. However, if the length of the notch 109 is long, the hole becomes too wide and the strength of holding the ear hook portion 107 decreases. Therefore, the length of the notch 109 is preferably about 1 to 2 cm.

(Explanation of seal area)
A seal region 111 containing a thermoplastic resin is formed in the face contact portion, which is a region in contact with the face of the fiber portion 103. The seal region 111 is formed on the fiber portion 103 by applying, adhering, or the like to a thermoplastic resin having a softening point of about 25 ° C. to 45 ° C. Further, the seal region 111 can be formed by impregnating the fibers with the thermoplastic resin and weaving the fibers impregnated with the thermoplastic resin. Such thermoplastic resins include ethylene-vinyl acetate copolymer (EVA), silicon resin, polyurethane resin, epoxy resin (cured), polyimide, polyethylene, polypropylene, polybutadiene, or polyvinyl acetate (PVA). be able to.

The thermoplastic resin softens at the user's body temperature and the hygiene mask deforms, so that the hygiene mask can be fitted to the face. By doing so, a hygiene mask that fits the face of many people can be obtained.

Further, a known shape memory resin may be used for the seal region 111. Examples of the shape memory resin include polynorbornene resin, transpolyisoprene resin, polyurethane resin, styrene-butadiene copolymer, and silicon resin.

When a shape memory resin having a glass transition point of 25 ° C. to 45 ° C. is used, the sanitary mask can be fitted to the face at a temperature equal to or higher than the glass transition point at the user's body temperature and can be fixed in that shape.

Such a resin does not get a rash even if it comes into contact with the skin for a long time. In addition, since such a resin does not easily adhere to makeup such as lipstick and foundation, it is not necessary to correct the makeup when wearing a mask. Therefore, it is preferable that the face contact portion is provided with the seal region 111 containing the resin.

The seal region 111 is preferably located at least in the region inside the notch 109. It is preferable that the upper and lower parts of the fiber portion 103, particularly the upper portion hanging on the nose, contain a thermoplastic resin in a region within 1 mm from the upper limit of the fiber portion in order to fit the hygiene mask to the face.

It is preferable that the seal region 111 is arranged at the face contact portion inside the notch 109 of the fiber portion 103 so as to be connected all around (here, in a square shape matching the outer shape of the fiber portion 103). It is preferable that it is not included in the area of contact at one point such as the tip of the nose or the tip of the lips. Further, if the region of the seal region 111 is large, the region through which air permeates decreases, so it is preferable that the seal region 111 is not very large.

Further, the seal region 111 may be included in the region including the folds 105. As described above, the folds 105 deform the shape of the fiber portion 103 according to the face. In that case, it is preferable that a part of the seal region 111 overlaps with the fold 105. By including the seal region 111 in the region including the folds 105, the shape of the fiber portion 103 can be fixed in a state of being fitted to the face.

(Explanation of the ear hook)
FIG. 3 is a schematic view of an ear hook portion according to an embodiment of the present invention. The ear hook portion of the present invention will be described with reference to FIG.

The ear hook portion 107 includes an elastic string portion 113. The string portion 113 has a sufficient length to be hung on the ear. The string portion 113 may include a mechanism for adjusting the length. For example, the length of the string can be freely adjusted by providing a string stopper or the like.

The ear hook portion 107 is provided with a non-deformable hook portion 115 having an enlarged width at both ends of the string portion 113. The hooking portion 115 may have a barb. As will be described later, the hooking portion 115 can fix the ear hooking portion 107 at an arbitrary position of the notch 109 of the fiber portion 103.

(Explanation of the structure that fixes the ear hook to the notch)
FIG. 4 is a schematic cross-sectional view of a notch in a fiber portion according to an embodiment of the present invention shown by AA of FIG. FIG. 5 is a schematic cross-sectional view in which the hooking portion of the ear hook portion is inserted into the notch. The structure for fixing the ear hook portion to the notch will be described with reference to FIGS. 4 and 5.

As shown in FIG. 4, the notch 109 of the fiber portion 103 includes a part 117 of the fiber portion and a bag portion 119. That is, the lower portion of the notch 109 is connected by the bag portion 119.

As shown in FIG. 5, the string portion 113 is connected to the fiber portion 103 by inserting the hooking portion 115 of the ear hook portion 107 into the notch 109. This insertion is made during the manufacturing process of the sanitary mask 101.

In this state, the ear hook portion 107 can move arbitrarily in the direction of the notch. Next, when the sanitary mask is worn by the user, the ear hook portion 107 is pulled, and the hook portion is fixed at an arbitrary position of the notch. By doing so, the hygiene mask is fixed at an arbitrary position on the user's face when worn. Therefore, it is possible to provide a hygiene mask that fits the face of many people.

INDUSTRIAL APPLICABILITY According to the present invention, a hygiene mask that fits the face independently of the skeleton of an individual and has a sufficient dustproof effect can be obtained. Therefore, the present invention can provide a hygienic mask that fits the face of many people. Further, according to the present invention, it is possible to perform face recognition by detecting with an infrared sensor even if the face cannot be seen by wearing a mask.

FIG. 6 is a schematic view of a sanitary mask according to a second embodiment of the present invention. The sanitary mask according to the second embodiment of the present invention will be described with reference to FIG.

The sanitary mask according to the second embodiment is different from the first embodiment in that the fiber portion faces the inside of the fiber portion and includes a peripheral portion that comes into contact with the face when worn. Further, the peripheral portion contains a thermoplastic resin, and the fiber portion does not contain a thermoplastic resin.

With reference to FIG. 6, the sanitary mask according to the second embodiment includes a left peripheral edge portion 123, a lower peripheral edge portion 125, and a right peripheral edge portion 127 facing inward to the fiber portion 121. These peripheral edges 123, 125, 127 prevent air that comes into contact with the face when the mask is worn and enters from the side surface of the fiber portion 121, that is, air that enters without passing through the fiber portion 121.

The peripheral portions 123, 125, 127 are impregnated with a thermoplastic resin to deform the shape so as to fit the face. Further, the inner circumference 129 of the upper part of the fiber portion 121 is also impregnated with the thermoplastic resin. By doing so, a sanitary mask that fits the shape of the face, prevents air from being taken in from the side surface, and has excellent dust prevention can be obtained.

The description of the embodiments described above is exemplary in all respects and is not restrictive. Modifications and changes can be made as appropriate for those skilled in the art. The scope of the present invention is shown not by the above-described embodiment but by the scope of claims. Further, the scope of the present invention includes modifications from the embodiment within the scope of the claims and within the scope of the claims.
