FIG. 3 is a cross-sectional view taken along the line III-III of the mask shown in FIG. 1 according to the embodiment of the present invention.

An embodiment of the present invention will be described. The mask 1 shown in FIGS. 1 and 2 includes a main body portion 10, a first shape holding member 20, a cushion member 30, a second shape holding member 40, and an ear hook portion 50. Each part of the mask 1 will be described below.

The main body 10 has a rectangular shape when viewed from the front and the back, and has a front surface 10a (outer surface when mounted) located on the front side of the main body 10 and a back surface 10b (when mounted) located on the back side of the main body 10. Has an inner surface). Further, the main body portion 10 has a slight thickness when viewed in a plan view, a side view, and a bottom view. Therefore, the main body 10 has a thin surface. The main body 10 is formed by three layers: a first layer 10A located on the front surface 10a side, a second layer 10B located between the front surface 10a and the back surface 10b, and a third layer 10C located on the back surface 10b side (). See also Figure 3). The first layer 10A, the second layer 10B, and the third layer 10C are formed in a thin film shape. The main body 10 can be formed of, for example, a non-woven fabric or a cloth material such as a woven fabric.

The main body portion 10 has a first storage portion 11. The first storage portion 11 is provided in the vicinity of one side of the main body portion 10 on the lateral end side in the lateral direction. The first storage portion 11 stores the first shape holding member 20, and is a space slightly larger than the outer shape of the first shape holding member 20 between the second layer 10B and the third layer 10C of the main body portion 10. (See also the enlarged view of part A in FIG. 3A). The first storage portion 11 is provided between the welding portions 11a provided in two rows along the longitudinal direction of the main body portion 10 and the welding portions 11a in the two rows, and one welding portion provided on both short sides of the main body portion 10. Formed by 11b. In other words, the first accommodating portion 11 is formed inside the welded portion 11a and the welded portion 11b. Further, the welded portion 11a and the welded portion 11b can be formed by welding the first layer 10A to the third layer 10C of the main body portion 10 by heat welding, ultrasonic welding, or the like. In the main body 10 (mask 1), the side located on the nose side of the mask 1 wearer is on the top, and the side located on the chin side of the mask 1 wearer is on the bottom, and the back surface 10b of the main body 10 is the front surface. The left side when looking at 10a is the left side, and the right side is the right side.

The main body portion 10 has a second storage portion 12. The second storage portion 12 is provided slightly below the center of the main body portion 10 in the lateral direction. The second storage portion 12 stores the second shape holding member 40, and is a space slightly larger than the outer shape of the second shape holding member 40 between the second layer 10B and the third layer 10C of the main body portion 10. (See also the enlarged view of part B in FIG. 3). The second storage portion 12 is formed between the welding portions 12a provided in two rows along the longitudinal direction of the main body portion 10. Further, the welded portion 12a can be formed by welding the first layer 10A to the third layer 10C of the main body portion 10 by heat welding, ultrasonic welding, or the like.

The main body 10 has a crease 13 extending in the longitudinal direction. The main body 10 has joints 14 on the verandas of both short sides. A plurality of creases 13 are provided between the joint portions 14 of the main body portion 10. As shown in FIG. 3, the main body 10 is bent by a plurality of creases 13. Then, the main body portion 10 is bent by the crease 13 to be formed so as to be folded over, and then the short side is welded (heat welding, ultrasonic welding, etc.) at the joint portion 14.

As shown by the broken lines in FIGS. 1 and 2, the first shape holding member 20 is formed in a plate shape in which the length in the longitudinal direction is much longer than the length in the lateral direction. The first shape holding member 20 has an elongated linear member 21 and a coating member 22 that covers the linear member 21. As shown in the enlarged view of FIG. 3A, the first shape holding member 20 has two linear members 21, and the coating member 22 covers the two linear members 21 and connects them to each other. It is formed. Therefore, the coating member 22 has a first coating member 22a that covers the linear member 21 in a circular shape and a second coating member 22b that connects the linear members 21 covered by the first coating member 22a in parallel. Further, the linear member 21 can be formed of, for example, a steel wire (steel wire rod), and the coating member 22 can be formed of a resin material (for example, a resin material containing polypropylene and polyethylene). Can be done. As the coating member 22, the one having the same color as the main body 10 is used. For example, if the main body 10 is white, the coating member 22 is also formed as white. Therefore, the main body 10 and the first shape holding member 20 are formed in the same color. As described above, the first shape holding member 20 is housed inside the main body 10 by the first storage part 11.

As shown in FIGS. 2 and 3, the cushion member 30 is arranged on the back surface 10b side of the main body 10 (one side of the main body 10). The cushion member 30 overlaps with the first shape holding member 20 in a plan view. Then, the cushion member 30 is fixed to the main body portion 10 by the welded portion 11a described above. Further, the cushion member 30 is thicker than the main body portion 10 and can be formed of an elastic member (for example, urethane material).

As shown by the broken lines in FIGS. 1 and 2, the second shape holding member 40 is formed in a plate shape in which the length in the longitudinal direction is much longer than the length in the lateral direction. Further, the second shape holding member 40 is formed to have a longer length in the longitudinal direction than the first shape holding member 20. The second shape-retaining member 40 is made of a resin material, and can be made of, for example, polyethylene. As described above, the second shape holding member 40 is housed inside the main body 10 by the second storage part 12.

The ear hook portion 50 is formed in a string shape. The ear hooks 50 are provided on both short sides of the main body 10, and are arranged symmetrically with respect to the center of the main body 10 in the longitudinal direction. The tip of the ear hook portion 50 is welded to the main body portion 10 (heat welding, ultrasonic welding, etc.) by the welding portions 50a provided near the four corners of the surface 10a of the main body portion 10. The ear hook portion 50 can be formed of rubber or the like.

Next, an example of how to use the mask 1 will be described. First, the user of the mask 1 folds the main body 10 in half so that the surface 10a of the main body 10 of the mask 1 is on the outside, with the main body 10 centered substantially in the lateral direction. Next, the folded portion of the main body 10 is pulled, and the folded portion is expanded by the crease 13 of the main body 10. Next, the user of the mask 1 puts the ear hook portion 50 of the mask 1 on his / her ear. Next, the user of the mask 1 grabs the longitudinal side of the main body 10 and spreads the main body 10 in the lateral direction so that the main body 10 covers his nose and chin.

Next, the user of the mask 1 applies a force to the first shape holding member 20 from above the main body portion 10 to deform the first shape holding member 20 so as to follow the shape of his nose. By deforming the first shape holding member 20, the mask 1 can be brought into close contact with the nose of the user, and the airtightness can be improved. Further, the first shape holding member 20 can maintain the deformed shape for a long time by using the linear member 21 as a steel wire. The steel wire has an advantage that it is thin and easy to process.

Here, since the first shape holding member 20 functions as a nose wire which is a wire for fixing the user's nose and the mask 1, it may have a length that can be fixed to the user's nose. By suppressing the length of the first shape holding member 20, it also contributes to the weight reduction of the mask 1.

Further, even if the first shape holding member 20 moves in the longitudinal direction of the main body portion 10 when the first shape holding member 20 is deformed, the movement is restricted by the welding portion 11b of the main body portion 10. Can be done. Therefore, the welding portions 11b provided at two locations on the main body portion 10 function not only as welding portions but also as a regulating portion that restricts the movement of the first shape holding member 20. The distance between the two regulation portions (welding portions 11b) is slightly larger than the length in the longitudinal direction of the first shape holding member 20 and shorter than the length in the longitudinal direction of the second storage portion 12.

Then, the main body portion 10 and the first shape holding member 20 are formed in the same color as described above. Therefore, even if the first shape holding member 20 is not deformed or the first shape holding member 20 is deformed, it is not noticeable from the outside and the design of the mask 1 is not impaired.

Further, when the first shape holding member 20 is deformed, the thick and elastic cushion member 30 comes into contact with the user's nose, and the gap between the user's nose and the main body 10 of the mask 1 The airtightness can be improved by filling. The mask 1 can be further improved in airtightness by filling the gap between the mask 1 and the user's nose by the cushion member 30 in addition to the above-mentioned deformation of the first shape holding member 20 that causes the mask 1 to adhere to the user's nose. .. This makes it possible to prevent the user from leaking exhaled breath, and even if the user wears glasses, it is possible to prevent the glasses from becoming cloudy.

Next, the user deforms the second shape holding member 40 so that the main body 10 protrudes from his / her face. By deforming the second shape holding member 40, the mask 1 does not move due to the exhalation of the user even when the mask 1 is worn. Therefore, the second shape holding member 40 functions as a center wire which is a wire deformed substantially at the center in the lateral direction of the mask 1. As described above, the user can wear the mask 1.

The present invention is not limited to the above-described embodiment. For example, the first storage portion 11 and the second storage portion 12 may be provided between the first layer 10A and the second layer 10B of the main body portion 10. Further, the shape of the mask 1 can be maintained by providing the first shape holding member 20 inside the main body 10 on both short sides.
