Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. In addition to the following embodiments, the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.

FIG. 1 shows a horizontal fold type sanitary mask (hereinafter, abbreviated as a mask) as an embodiment of the present invention. The mask includes a covering portion 10 that covers the wearer's mouth, nose, and their surroundings, and two ear hook portions 12 that extend from both side ends of the covering portion 10 and are hung on both ears. The covering portion 10 is made of a plurality of breathable sheets, and in the mask of the present embodiment, the cover portion 10 is made of a breathable material in which three sheets 14, 16 and 18 are superposed as shown in FIG. The sheets 14, 16 and 18 are non-woven fabrics made of thermoplastic synthetic fibers in the mask of the present embodiment.

As shown in FIG. 1, a plurality of lateral folds extending in the lateral direction are formed in the covering portion 10, and five lateral folds 20, 22, 24, 26, 28 are formed in the mask of the present embodiment. As shown in FIG. 2, the five lateral folds 20, 22, 24, 26, and 28 include three side walls, and a mountain fold portion 30 is formed by the front side wall and the center side wall. At the same time, a valley fold portion 32 is formed by the side wall on the back side and the side wall in the middle. However, the mountain folds 30a of the two horizontal folds 20 and 22 on the upper side have their tops located above the bottom of the valley folds 32a and are upward, but the three horizontal folds 24 and 24 on the lower side. The tops of the mountain folds 30b of 26 and 28 are located below the bottom of the valley folds 32b and face downward. That is, the two horizontal folds 20 and 22 on the upper side are in a state of being convex upward when viewed from the front side of the covering portion 10, and the three horizontal folds 24, 26 and 28 on the lower side are in a state of being convex downward. It has become.

Since the five horizontal folds are configured as described above, the covering portion 10 includes one box fold 36 and three car folds. The box fold 36 is composed of a second upwardly convex horizontal fold 22 from the top and a third downwardly convex horizontal fold 24 from the top. Further, the horizontal folds 20 located on the upper side of the box folds 36 and the two horizontal folds 26 and 28 located on the lower side of the box folds 36 are car folds. In the following description, the horizontal folds 20 may be referred to as upper vehicle folds 20, and the horizontal folds 26 and 28 may be referred to as lower vehicle folds 26 and 28.

The covering portion 10 is composed of three sheets 14, 16 and 18 as described above, but the vertical dimension of the innermost sheet 14, that is, the sheet 14 in contact with the skin of the face is made larger than the other sheets 16 and 18. The upper end and the lower end protruding vertically from the sheets 16 and 18 are folded outward to form the folded portions 40 and 42 covering the upper and lower ends of the sheets 16 and 18, respectively. As shown in FIG. 1, the lower folded-back portion 42 is pressurized and heated to weld the main body portion (the portion that is not folded outward) of the sheet 14 and the sheets 16 and 18 at the joint portion 44 extending in the lateral direction. And joined. The joint portion 44 has a plurality of welding points, which are point-shaped welding portions, arranged at equal intervals and in a straight line.

The upper folded portion 40 is welded at two joint portions 50 and 52 parallel to each other. Similar to the joint portion 40, these joint portions 50 and 52 are formed by arranging a plurality of welding points at equal intervals and in a straight line, and have a tubular shape extending laterally between the folded portion 40 and the sheet 18 in the covering portion 10. A portion 54 (see FIG. 2) is formed, and a bar 56 is arranged therein. The bar 56 is a plastically deformable member having a narrow and thin elongated plate shape, and in the mask of the present embodiment, is made of a known material that is plastically deformable and is formed of polyethylene to which an additive is added. It is in a state of being inserted into the tubular portion 54 and extending in the lateral direction of the covering portion 10.

As shown in FIG. 1, both end portions of the ear hook portion 12 are joined to the upper corner portion and the lower corner portion of both side end portions of the cover portion 10. Each ear hook portion 12 is formed of a thermoplastic synthetic resin material into a string shape having good elasticity, and is joined to the covering portion 10 by welding.

In the covering portion 10, the side walls of the lateral folds 20, 22, 24, 26, and 28 are welded by pressurization and heating across the vertical direction on both sides in the lateral direction. That is, the covering portion 10 has a pair of joint portions 60 that prevent the portions on both sides of the lateral folds 20, 22, 24, 26, and 28 in the lateral direction from unfolding. Each of the pair of joints 60 is divided into two in the vertical direction of the cover portion 10, the upper joint line portion 62 located above the middle and extending linearly, and the upper joint line portion 62 below the middle. It is composed of a lower joint wire portion 64 which is located on the side and extends linearly. In the upper joint line portion 62 and the lower joint line portion 64, a plurality of welding points are linearly arranged at equal intervals, similarly to the joint portions 40, 50, and 52.

The upper joint line portion 62 joins the side walls of the upper wheel fold 20 and the upwardly convex lateral fold 22 forming the box fold 36, and extends from the upper folded portion 40 over the box fold 36. That is, the welding point 70 at the lower end of the upper joint line portion 62 is located substantially at the center of the box fold 36 in the vertical direction. Further, the upper joint line portion 62 has a shape curved so as to be convex outward in the lateral direction. More specifically, the upper joint line portion 62 has an arc shape that is convex outward in the lateral direction.

The lower joint line portion 64 joins the side walls of the downwardly convex horizontal folds 24 forming the box folds 36 and the lower wheel folds 26 and 28, and extends from the box folds 36 to the lower folded portion 42. It is extending. More specifically, it extends straight from the side end of the cover portion 10 to the lower end of the cover portion 10, specifically, from the side end of the box fold 36 to the lower end of the lower folded portion 42. Further, the lower joining line portion 64 is inclined toward the center side in the lateral direction of the covering portion 10 from the upper end to the lower end.

The welding point 72 at the upper end of the lower joint line portion 64 is located substantially at the center of the box fold 36 in the vertical direction. However, the welding point 72 at the upper end of the lower joining wire portion 64 and the welding point 70 at the lower end of the upper joining wire portion 62 described above are located at positions separated from each other in the lateral direction. More specifically, the welding point 70 at the lower end of the upper joining line portion 62 is located on the central side in the lateral direction from the welding point 72 at the upper end of the lower joining line portion 64. Further, the lower end of the upper joint line portion 62 and the upper end of the lower joint line portion 64 are set to have the same height. Strictly speaking, the lower end of the upper joint line portion 62 and the upper end of the lower joint line portion 64 are slightly separated in the vertical direction, but the lower end of the upper joint line portion 62 is the lower joint line portion 64. There is a positional relationship that is not separated from the welding point 72 at the upper end by one welding point or more upward. In the present specification, when they are separated by such a degree, they are included in being "at the same height".

As shown in FIG. 3, when a person wears the mask of the present embodiment, each ear hook portion 12 is hung on the ear, and the central portion of the cover portion 10 in the left-right direction is extended vertically to extend the nose and mouth. Be made to cover. Then, if the bar 56 is bent along the surface of the nose, the upper end portion of the covering portion 10 is prevented from being displaced downward. The side ends on both sides of the covering portion 10 are pulled by the ear hook portions 12 to cover the wearer's cheeks. Further, as shown in FIG. 3, the horizontal fold type sanitary mask as in the present embodiment is worn so that the lower end of the covering portion 10 extends below the chin and also covers the chin. It is common. However, as shown in FIG. 4, there is a case where the lower end of the covering portion 10 is stopped to the bottom of the mouth and is worn without covering the chin (so-called half-hanging state). Then, in such a case, when a mask having a single linear shape in which each of the pair of joints extends in the vertical direction as in the conventional case is worn without covering the chin, the covering portion 10 There is a risk of a gap between the skin and the skin of the face.

In the mask of the present embodiment, the lower ends of the upper joint line portions 62 and the upper ends of the lower joint line portions 64 on both sides in the lateral direction of the cover portion 10 are provided with a lateral spacing, and are compared with the other portions. It is easy to bend. Further, as described above, each of the upper joint line portions 62 of the pair of joint portions 60 has a shape in which the center in the vertical direction is curved toward the outer side in the lateral direction, so that it is easy to follow the cheek. There is. Further, each lower joint line portion 64 of the pair of joint portions 60 is inclined toward the center side in the lateral direction of the cover portion 10 from the upper end to the lower end, and the side end of the cover portion 10. By extending from the cover to the lower end of the covering portion 10, in the case of the general wearing method as shown in FIG. 3, not only the adhesion of the face to the skin is ensured, but also as shown in FIG. Even in the case of the wearing method, since the lower joint line portion 64 follows the shape of the cheek, it is considered that it is possible to suppress a decrease in the adhesion of the face to the skin.

In the mask of the present embodiment, the lower end of the upper joint line portion 62 and the upper end of the lower joint line portion 64 are located at the center of the box folds 36. Therefore, the upper joint line portion 62 joins the side walls of the lateral folds 20 and 22 that are convex upward, and the lower joint line portion 64 joins the side walls of the horizontal folds 24, 26, 28 that are convex downward. Therefore, when the mask is attached by extending the covering portion 10 vertically, the bending position of the side end of the covering portion 10 is an appropriate position.

Incidentally, in the mask of the present embodiment, the angle θ ₁ formed with respect to the side end (straight line extending in the vertical direction) of the covering portion 10 of the lower joining line portion 64 is set to be about 25 °. If the angle θ ₁ is too small, there will be a gap between the covering portion 10 and the skin of the face, similar to a conventional mask in which each of the pair of joints is a single linear mask extending in the vertical direction. Even if the angle θ ₁ is too large, it may not match the shape of the cheeks and a gap may be formed between the covering portion 10 and the skin of the face. Therefore, the angle θ ₁ formed with respect to the side end of the covering portion 10 of the lower joining line portion 64 is preferably 15 ° or more and less than 35 °, and more preferably 20 ° or more and less than 30 °.

Further, in the mask of the present embodiment, the lateral distance t between the welding point 70 of the upper joining wire portion 62 and the welding point 72 of the lower joining wire portion 64 is about 7% of the vertical dimension of the covering portion 10. It is said that. If the distance t is too small, deformation between the upper joint line portion 62 and the lower joint line portion 64 is difficult to tolerate, and if the distance t is too large, the upper joint line portion 62 and the lower joint line portion 64 There is a risk that the gap between the skin and the skin will become large and that part will float from the skin of the face. Therefore, it is desirable that the lateral distance t between the lower end of the upper joint line portion 62 and the upper end of the lower joint line portion 64 is 5% or more and less than 10% of the vertical dimension of the covering portion 10.

The upper joint line portion and the lower joint line portion of the pair of joint portions may be shaped like a mask schematically shown in FIG. The components having the same function as the masks of the embodiments shown in FIGS. 1 to 4 are designated by the same reference numerals to indicate the correspondence relationship, and the description thereof will be omitted.

In the mask shown in FIG. 5, each upper joint line portion 102 of the pair of joint portions 100 bulges outward in the lateral direction, similarly to the upper joint line portion 62 of the mask of the above embodiment. However, the shape of the upper part of the upper joint line portion 102 is similar to the shape of a heart, and has aesthetics and fashionability. Further, the lower joint line portion 104 is inclined toward the center side in the lateral direction of the cover portion 10 from the upper end to the lower end, similarly to the lower joint line portion 64 of the mask of the above embodiment. However, the lower joint line portion 104 does not extend straight like the lower joint line portion 64 of the mask of the above embodiment, and has a wavy shape. The lower joint line portion 104 has an angle θ ₂ formed with respect to the side end of the straight line covering portion 10 connecting the upper end and the lower end, which is about 25 °, which is the same as θ ₁ .

The lower end of the upper joint line portion 102 is located on the central side in the lateral direction from the upper end of the lower joint line portion 104, and the lower end of the upper joint line portion 102 and the upper end of the lower joint line portion 104 are laterally oriented. The interval between the two is about 7% of the vertical dimension of the covering portion 10, similarly to the mask of the above embodiment. However, the lower end of the upper joint line portion 102 is located below the upper end of the lower joint line portion 104. Specifically, the two welding points from the lower side of the upper joining line 102 and the two welding points from the upper side of the lower joining line portion 104 overlap each other in the vertical direction in a laterally separated state. .. If the overlapping dimension h of the upper joint line portion 102 and the lower joint line portion 104 in the vertical direction becomes too large, it is difficult to allow deformation between the upper joint line portion 102 and the lower joint line portion 104. Therefore, it is desirable that this dimension h is 8% or less of the vertical dimension of the covering portion 10.

Similar to the mask of the above embodiment, the mask shown in FIG. 5 having a pair of joints 100 having the above-mentioned shape is also the skin of the face when the mask is covered under the chin by the covering portion 10. Not only does it ensure adhesion to the skin, but it also reduces the adhesion of the face to the skin even when the cover is worn so that the lower end of the cover is under the mouth without covering under the chin. It is thought that it can be suppressed.
