The mask 1 enhances comfort during use.
The material of the mask 1 is composed of at least the first base material 10 and the second base material 20.

A knit fabric is used as the material of the first base material 10, and since it has elasticity, it is effective as a material for a mask.

For the first base material 10, an embodiment in which an antiviral agent is applied, that is, an embodiment in which the surface of the base material is coated or impregnated with the antiviral agent can be adopted. Antiviral agents include, for example, amino acid silver such as silver L-pyrrolidone carboxylate and zinc L-pyrrolidone carboxylate, amino acid copper ions such as amino acid zinc and silver pyrrolidone carboxylate, and also include citric acid, glutamate and sulfuric acid. An antibacterial and antiviral composition for fibers. These various organic acids are added as stabilizers and fiber binders, and antiviral agents having these compositions can significantly reduce the number of viruses. Although antiviral agents are effective against viruses, it is better not to come into direct contact with the skin to prevent the chemicals from harming the user's skin.

The second base material 20 is a base material on the side that comes into direct contact with the skin. A breathable polyurethane sheet is used. By using the foamed polyurethane sheet, the frame laminating process can be performed on the first base material 10 and the second base material 20.
The frame laminating process is to melt a soft urethane foam such as a polyurethane sheet and bond it to another base material. Since the soft urethane foam and the fabric of the other party are welded on the entire surface of the fabric, they will not come off, slip, or come close to each other. Even if it is cut, it will not come off from that part. Therefore, the first base material 10 and the second base material 20 can be treated as a completely integrated base material after being frame-laminated (FIG. 3A).
The polyurethane sheet can be made into a breathable, stretchable, and breathable material by adjusting the amount of foaming. By integrating the second base material 20 and the first base material 10, which are such materials, by frame laminating processing, it is possible to integrate them while maintaining breathability and elasticity. Therefore, it adheres to the face and can suppress the invasion of the virus from the gap, and can be a particularly effective base material as an antiviral mask.

Further, the third base material 30 can be frame-laminated on the inside of the second base material 20 and on the side in direct contact with the skin. The third base material 30 is a base material made of a cloth such as knit and not subjected to an antiviral agent. The first base material 10 and the second base material 20 satisfy the requirements of the mask, but by using a cloth such as knit for the lining, the skin feel is improved and the comfort during use can be enhanced. The frame laminating process can be performed on both the front surface and the back surface of the soft urethane foam. After the first base material 10 and the second base material 20 are frame-laminated, the synthetic base material 10 and the second base material 20 and the third base material 30 are frame-laminated to form the first base material. The material 10, the second base material 20, and the third base material 30 can be integrated into a base material.
By using this base material as a mask, it is possible to make a mask that does not shift or shift during use and has a good skin feel (FIG. 3 (b)).

Further, by performing a UV cut treatment on the third base material 30, it is possible to provide a UV cut function. Since an antiviral agent may be applied to the first base material 10, it is better not to contain other components. If it is the third base material 30, it can be impregnated with a UV blocking component. Since UV light is attenuated by the first base material 10 and the second base material 20, it can be more effective by giving the third base material 30 a UV cut function (FIG. 3 (c)). ..

The mask 1 is functionally composed of two mask halves 40 on the left and right. By suturing the two mask halves 40 to form the mask 1, the mask 1 can be formed into a three-dimensional shape.
The mask half body 40 is composed of a cover half portion 42 and an ear hook portion 43. The cover half portion 42 forms a cover portion 41 with the left and right cover half portions 42, and covers the entire vicinity of the nose and mouth. One of the cover half portions 42 is connected to the ear hook portion 43. The selvage portion 43 is for holding the mask 1 by the selvage portion E, has an opening portion, and hangs the opening portion on the selvage portion E. Since the base material of the mask 1 is the first base material 10 and the second base material 20, both have elasticity, and by hanging the opening on the selvage portion E, tension is applied to the entire mask 1 and the half-covered portion is covered. 42 can be brought into close contact with the face.

There is a joint 50 on the end side of the cover half 42 opposite to the ear hook 43. The two left and right mask halves 40 are connected by a joint 50. The joint portion 50 has a curved shape bulging outward, and after the mask half body 40 is connected by the joint portion 50, the joint portion 50 joined when the two mask half bodies 40 are unfolded is outside the mask. Will swell to. Then, when the mask 1 is attached to the face F, the joint portion 50 is located at a position corresponding to the tip of the nostril and the mouth, so that a space is formed around the nostrils and the mouth to facilitate breathing (FIG. 2).

The joint 50 is sutured at the main suture 51 by the suture 54. By suturing at the main suture portion 51, the two mask halves 40 are integrated. Since the end portion of the joint portion 50 will protrude, the joint portion 50 is divided into left and right parts and sutured with the end portion treated suture portion 52.

The manufacturing process of the mask 1 will be described with reference to FIG. The first base material 10 and the second base material 20, which are knit fabrics, are welded by a frame laminating process. Specifically, the surface of the second base material 20 is heated to a high temperature with a burner or the like, melted, and pressed against the first base material 10 before it hardens, so that a part of the second base material 20 becomes the first base material 10. It penetrates and becomes an integral base material (FIG. 4 (a)).

The left and right mask halves 40 are punched into the integrated base material. Since the first base material 10 and the second base material 20 are integrated on all surfaces, the first base material 10 and the second base material 20 do not peel off, including the holes (FIG. 4 (b)). ).
The mask halves 40 are aligned so that the first base material 10 fits together, and the mask halves 40 are joined at the joining portion 50. By this operation of suturing along the main suture portion 51 using the suture thread 54, the two mask halves 40 are integrated (FIG. 4 (c)).

Since the end of the tip of the main suture portion 51 of the joint portion 50 protrudes and hits the nose, mouth, etc., the end portion is sutured along the end treatment suture portion 52 so as to be along the cover portion 41 (FIG. 4). (D)).
Mask 1 is completed (FIG. 4 (e)).
As described above, by using the frame-laminated base material of the first base material 10 and the second base material 20, the base material does not shift or shift during use, and can be used as one base material even in the manufacturing process. Since it can be handled, the work process can be simplified.

Further, by using a base material obtained by frame-laminating the first base material 10, the second base material 20, and the third base material 30, the base material does not shift or shift during use, and further, comfort during use. It is possible to manufacture a mask that improves the quality of the product with almost no increase in the manufacturing process.

The joint portion 50 will be described with reference to FIG. 5 is a cross-sectional view of AA of FIG. 1 (a).
FIG. 5A is a cross-sectional view of the structure of the joint portion 50 described above. The upper part of the paper is the surface, and the lower part is the side that touches the skin. The base material is composed of the first base material 10 and the second base material 20, but the same structure is obtained when the base material is composed of the first base material 10, the second base material 20, and the third base material 30. ..
The two mask halves 40 are in contact at the center and are sutured at the main suture portion 51 by the suture thread 54. With this suture, the two mask halves 40 are fixed and integrated. The end portion beyond the main suture portion 51 is folded back to the left and right, and is sutured by the left and right end processing suture portions 52. Therefore, no protrusion is generated inside the joint portion 50. A part of the first base material 10 wraps around inward, but the area is extremely small, and even if the first base material 10 is applied with an antiviral agent, it causes almost no harm to the human body.

In addition, if you are worried that the cloth impregnated with the drug will come into contact with the skin even if it is a small amount, or if you use a drug that is more harmful, you can avoid the problem by using the following structure. Can be done.
5 (b) shows FIG. 5 (a) provided with a covering sheet 31. A part of the first base material 10 covers a region that wraps around inward. End processing Since the suture portion 52 is sutured together with the end portion, the suturing work does not increase. The cover sheet 31 may be a knit fabric or the like.
FIG. 5C shows a case where the end treatment suture portion 52 is used on only one of the left and right sides. Since the first base material 10 is sandwiched between the second base materials 20 and hidden, the first base material 10 does not come into contact with the skin. In addition, the suturing work of the end processing suture portion 52 can be reduced.
FIG. 5D shows only suturing the main suture portion 51. By accurately and reducing the shape of the tip end of the main suture portion 51 of the joint portion 50, the amount of protrusion to the inside of the mask is limited, and only the end portion of the main suture portion 51 is sutured. be. Since the first base material 10 is sandwiched between the second base materials 20 and hidden, the first base material 10 does not come into contact with the skin. In addition, the suturing work of the end processing suture portion 52 can be reduced.
FIG. 5 (e) shows a conventional joining mode of the joining portion 50, unlike the present invention. That is, since the second base materials 20 which are polyurethane sheets come into contact with each other by turning the end portions outward, the bonding is performed by welding instead of stitching at the main stitching portion 51. Adhesive may be used in addition to welding. It is a conventional joining means when polyurethane sheets come into contact with each other.

FIG. 6 shows an example of further improving the comfort of the user. 6 (a) is a back view of the mask, and FIG. 6 (b) is a front view of the mask.
If the cut side of the base material is rough, it is possible that the part that hits the ear or the like may feel rough when the mask is worn. In that case, it is possible to reduce roughness by edging the vicinity of the cut edge.
Specifically, a strip-shaped cloth 55 that covers the cut side is prepared, the edging suture portion 53 of the cut side is covered with the strip-shaped cloth 55, and binder stitching is performed. Etc. can be reduced. The edging suture portion 53 may be located only in the vicinity of the ear hook, or may be on all sides of the nose, mouth, and cheeks.

As described above, according to the present invention, in the mask, it is possible to prevent the cloth from slipping, leaning, unevenness, etc. at the time of wearing, and it is possible to improve the comfort of the user.
Further, by integrating the base materials, the process can be performed on one sheet of fabric, so that the work efficiency at the time of manufacturing can be improved.

Further, according to the present invention, by applying the antiviral agent to the first base material 10, the invasion of the virus into the body as an antiviral mask is suppressed, and the harm caused by the contact of the antiviral agent with the skin is prevented. It is possible to improve safety and comfort during use.

It is understood that the mask according to the present invention has great industrial applicability as a technique for improving comfort when worn.
