Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the present embodiment, the mask is described as an example in which the mask forms a three-dimensional shape and is folded in half along the center line of the mask body, but the mask is not limited to this type.

As shown in FIGS. 1 to 3, the mask 1 includes a mask main body 2 that is worn on the user's face and a pair of ear hooks 3 that are worn on both ears of the user. The mask 1 is integrally formed of porous foamed polyurethane (for example, polyurethane having a thickness of 2 to 3 mm).
The mask 1 is formed by stacking two sheet materials of the same shape and stitching the curved peripheral edges of one end thereof, and the mask main body 2 and the pair of ear hooks 3 are continuous and integrally formed. Has become.

When the mask 1 is not used, as shown in FIG. 1, the mask main body 2 is folded in half and the pair of ear hooks 3 are in a state of being overlapped with each other. When the mask 1 is used, as shown in FIG. 2, by pulling and deploying the pair of ear hooks 3 to the opposite sides so as to separate them from each other, the mask body 2 swells forward and can be mounted on the face. It becomes a three-dimensional shape.

That is, in the mask main body 2, the stitched portion 8 is formed by stitching the curved peripheral edges of the one ends of the two sheet materials. Therefore, when the mask 1 is deployed, the stitched portion 8 side has a shape that gently protrudes forward. Thus, when the mask 1 is attached to the user's face, the mask body 2 covers the mouth and nostrils of the face, and an appropriate space is formed between the inner surface of the mask body 2 and the face. In addition, the mask body 2 is in a state in which the suture portion 8 extends in the vertical direction of the face when the mask 1 is worn on the face. The mask body 2 has a width of about 10 cm and a length of about 12 cm.

The pair of ear hooks 3 extend from the left and right ends of the mask body 2 toward the ears of the face. The ear hook 3 includes an opening 9 into which the user's ear is inserted, a cut-and-raised piece 5, a strip portion 6, and an engaging portion 7 that engages with the back side of the user's ear when the mask is used. ing. The ear hook 3 has a width of about 8 cm and a length of about 8.5 cm.

The cut-and-raised piece 5 is cut and raised in a horizontally long, substantially elliptical shape through a horizontally long C-shaped cutting line 4 formed in a substantially central region of the ear hook 3.
The cut-and-raised piece 5 is cut by the cutting line 4 and is separated from the ear hook 3 except for the base end portion 5b, that is, the base end 5b of the cut-and-raised piece 5 remains integral with the ear hook portion 3. Not separated. The cut-and-raised piece 5 preferably has a width of about 6 cm and a length of about 4.5 cm.

The opening 9 is formed by cutting and raising the cut-and-raised piece 5 outward with the base end portion 5b as a base point. Therefore, the opening 9 has a substantially elliptical shape like the cut-and-raised piece 5. When the user's ear is inserted into the opening 9, the ear hook 3 is pulled behind the user's ear.
The foamed polyurethane forming the mask 1 has appropriate elasticity, flexibility and elasticity. Therefore, when the mask 1 is attached to the user's face, the mask 1 is pulled to the rear of the ear by utilizing the expansion and contraction of the ear hook 3 including the mask body 2, and the elastic force of the mask 1 is increased. Is held in close contact with the face.

The ear hooking portion 3 is formed with a strip-shaped portion 6 extending to both upper and lower sides of the cut-and-raised piece 5 and the end side. An engaging portion 7 is formed for engaging with.
Here, the strip-shaped portion 6 is a wide string-shaped portion in which the upper strip portion 6a, the end-side strip portion 6b, and the lower strip portion 6c are continuously formed integrally. It is preferable that the upper band portion 6a and the lower band portion 6c have a width of about 1.0 cm to 1.5 cm, and the end portion side band portion 6b have a width of about 2 cm.

Next, the engagement portion 7 formed by winding the cut-and-raised piece 5 around the end portion side band portion 6b when the user wears the mask 1 will be described in detail.
4(a) to 4(c) show a state before the user wears the mask 1 (unused state).
From the state of FIG. 4(a), as shown in FIG. 4(b), first, the cut-and-raised piece 5 is first folded outward by 180°. As a result, the opening 9 is formed.

Next, as shown in FIG. 4( c ), the cut-and-raised piece 5 is further folded inwardly by 180° and wound around the end side strip portion 6 b of the strip portion 6. At this time, the surface of the tip 5a of the cut-and-raised piece 5 appears below the opening 9.

Next, as shown in FIG. 4(d), the tip end portion 5a of the cut-and-raised piece 5 is further folded outward by 180° to form an engaging portion 7 having cushioning properties with the sheet material superposed thereon. This state is a use state in which the user wears the mask 1.
In other words, when the user wears the mask 1, the engaging portion 7 is formed by winding the cut-and-raised piece 5 around the end side belt portion 6b for about one and a half turns, so that at least the sheet materials are stacked in three to four layers. When fitted together, it will engage the back of the user's ear.

Then, as shown in FIGS. 5 and 6, when the user wears the mask 1, the ear is inserted from the inside of the opening 9 and the expansion and contraction of the ear hook 3 is used to move the ear hook 3 to the ear. Is pulled back to engage the engaging portion 7 with the back side of the ear, and the suture portion 8 of the mask main body portion 2 is attached so as to be located at the center of the nose.

The mask 1 of the present embodiment described above extends integrally from the left and right ends of the mask body 2 to the ear side of the face, with the mask body 2 having a size that covers at least the mouth and nostrils of the user's face when worn. And a pair of ear hooks 3 that can be hung on the ears. The ear hook 3 is formed with a horizontally elongated, substantially elliptical cut-and-raised piece 5 through a C-shaped cutting line 4 that can be cut and raised from the face side to the end side. A band-like portion 6 is formed on both upper and lower sides and the end side of the cut-and-raised piece 5, and the cut-and-raised piece 5 is wound around the end-side band portion 6b of the band-shaped portion 6 to engage with the back side of the user's ear. Since the engaging portion 7 is formed, it is possible to ensure a comfortable wearing comfort in which the back side of the ear does not hurt even when worn for a long time.

Further, since the mask 1 of the present embodiment is formed of a porous polyurethane sheet material, it can be washed and used many times, and thus can be used for a long time.

Next, a modified example in which the above embodiment is partially modified will be described.
1] In the above-described embodiment, the mask in which the center of the mask main body is sewn together has been described as an example, but the present invention is not limited to the sewn together. For example, the center of the mask main body is pressed by heat fusion. It may be a mask.

2] In the above-described embodiment, when the cut-and-raised piece is wound around the end side band portion to form the engagement portion, the mask is described as an example in which the cut-and-raised piece is folded 180° in total three times. It suffices if it is wound around the end side band portion, and is not limited to three times.
3] An antibacterial and deodorant substance (such as bamboo charcoal) may be applied to the surface of the mask body.
