Description

The present invention relates to a three-dimensional mask with improved stretchability. Specifically, the mask body is formed so that the front surface of the mask swells in a convex shape to improve ease of use such as breathlessness and pressure around the nose or mouth. The present invention relates to a three-dimensional mask that improves the performance and can cope with various face sizes.

Conventionally, various contrivances have been made for masks in order to improve the wearing feeling on the face. As shown in FIG. 4 as a perspective view of the mask from the front side, the mask B has a size and shape sufficient to cover the mouth and nostril, and is a mask body 11 in which a plurality of woven fabrics or nonwoven fabrics such as gauze are overlapped. The left and right side edges 13 and 13 'are provided with rubber ring-like ear straps 12 and 12', respectively. A V-cut sew-and-shrink portion 15 is provided at the center of the upper edge 14 of the mask body 11. By sewing and shrinking the central portion of the mask main body 11 in a V-cut shape, the vertical dimension swelled in a convex shape at the central portion becomes longer than the left and right side edges 13, 13 '.

As shown in FIG. 5 as a perspective view of the mask B as seen from the back side, a concave portion 19 is formed in the central portion of the mask body 11 so as to be recessed in the portion facing the nose and mouth. And a space between the mouth. As an effect, it is possible to eliminate the difficulty of breathing when wearing the mask and the discomfort due to the close contact.

In this conventional mask, the vertical elasticity of the mask body 11 is poor, so a single size mask can be used for large faces, small faces, thin people, fat people, people with long faces, and short people. Cannot be used. Similarly, a single size mask cannot be worn for both adults and children. In addition, since the space from the nose to the mouth cannot be expanded on the back surface of the mask, the lips touch the surface of the mask and feel uncomfortable, and the lipstick adheres to the surface of the mask and is unsanitary.

As in recent years, infectious and more malicious viruses have been discovered one after another, and many people are suffering from hay fever every season, or various production facilities and disposal Considering the health management of people who are exposed to harmful dust at physical treatment facilities, etc., the mask that is the easiest solution for these is one size regardless of the size of the face. A mask that can be worn is needed.

Therefore, the object of the present invention is to provide a mask body made of woven fabric or non-woven fabric such as gauze, and the mask surface with ear straps attached to the left and right side edges, respectively, in the left-right direction of the mask body. By providing a plurality of wrinkles, a three-dimensional mask is provided which is rich in elasticity following the surface from the nose and chin to the cheek and can be worn by anyone regardless of the size of the face in one size.

In order to achieve the above object, the three-dimensional mask according to the present invention has an ear strap 2 on each of the left and right side edges 3, 3 'of the mask body 1 having a size and shape sufficient to cover the mouth and nostril, 2 'is attached, the central portion of the upper edge 4 of the mask body 1 is sewn in a V-cut shape, and the front surface of the mask body 1 is formed in a convex shape. 1 is a three-dimensional mask characterized in that ridges 10 are applied in the left-right direction.

The mask according to the present invention having the above-described configuration has the following excellent functions as compared with the conventional mask. By providing multiple pleats in the left and right direction of the mask body, the elasticity of the mask body improves following the surface from the nose and chin to the cheek, so everyone can use one size regardless of the size of the face Can be worn. In addition, since the space is enlarged following the surface from the nose and chin to the cheek, the lips do not touch the mask surface, and a sense of incongruity does not occur, and lipstick does not adhere, which is hygienic.

Embodiments of the present invention will be specifically described below based on examples of the present invention shown in the accompanying drawings.

First, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of the unfolded mask A in this embodiment as seen from the front side, FIG. 2 is a perspective view of the mask A as seen from the back side, and FIG. 3 is an explanatory view of the state where the mask A is mounted. .

As shown in FIG. 1 as a perspective view seen from the front side of the mask A, the mask A includes a mask body 1 having a size and shape sufficient to cover the mouth and nostrils, and left and right side edges 3 of the mask body 1. Each of 3 'is provided with rubber ring-like ear straps 2, 2'. Then, at the center of the upper edge 4 of the mask body 1, a V-cut sew-and-shrink part 5 is provided. By curving the central portion of the edge 4 above the mask body 1 with a V-cut, the curve bulging from the top to the bottom of the central portion becomes longer than the left and right side edges 3, 3 '. In this manner, the mask body 1 is formed with the convex portion 8 that swells from the top to the bottom of the central portion, and becomes a three-dimensional mask.

On the other hand, as shown in FIG. 2 as a perspective view seen from the back side of the mask A, the edges 4 and 4 above the mask body 1 are divided into left and right from the seam shrinking portion 5, and these edges 4 and 4 and the mask body 1 above The inclined surfaces 7 and 7 are formed by the portion. And the inclined surfaces 7 and 7 form the surface inclined right and left by using the line which connects the vertex P and the vertex Q as a ridge. In this way, on the back surface of the mask A, a concave portion 9 is formed in which the inclined surfaces 7 and 7 formed in a bowl shape are covered from above.

In the mask A configured as described above, the ridges 10 and 10 that are pleated from the side end side 3 toward the side end side 3 ′ in the mask main body 1 are provided in parallel. The folds 10 and 10 are made by double-folding the cloth of the mask main body 1 and are formed by folding along the swelled shape of the convex portion 8 on the surface. Here, the ridge 10 is formed by simply applying heat, applying pressure, a wet heat pressurizing method, or the like using the thermoplasticity of a woven or non-woven fabric such as gauze.

It is comprised as mentioned above, Next, an effect | action is demonstrated.

Needless to say, the function required of the mask is to prevent pollen, dust, or fine particles such as viruses, which are harmful to the body, from being sucked into the body together with exhaled air.

For this purpose, the material and shape of the mask body 1 are examined with regard to the three-dimensional shape of the face, particularly those that closely adhere to the raised shape of the nose or the cheeks of the face, and the mask body 1 is adjusted to the size of the face. It is important to expand and contract accordingly.

As shown in FIG. 3, the state where the mask A is attached to the face is located at the front portion of the nose portion N, and the edges 4 and 4 of the mask A are located slightly below the nose root portion U to the nose back of the nose portion N. Along the left and right sides of the nose portion, the close contact follows the raised shape of the nose N. On the other hand, the face from the jaw M at the lower face to the cheek adheres along the edges 6 and 6 of the mask A. Since the mask A is deformed following the surface from the jaw portion M to the cheek, the airtightness of this portion is sufficiently ensured.

And since the recessed part 9 is formed in the mask main body 1 in the back surface of the mask A, this recessed part 9 functions as the clearance space S which swells toward the outer side of a mask. Since the mask body 1 is provided with the folds 10 and 10 on which the cloth is overlapped, the fold spreads according to the size of the face, the mask body 1 extends vertically, and the area of the mask increases.

As described above, the nose portion N of the face adheres along the edges 4 and 4, and the face from the jaw portion M to the cheek adheres along the edges 6 and 6. The nose, mouth and cheeks of the face are shielded from the outside world, and a clear space S bulging outward from the mask is formed, so that the mask body 1 is in close contact with the nose and mouth and is uncomfortable. There is no need to read. Furthermore, since the mask body 1 is provided with the ridges 10 and 10, the folds expand and the mouth space expands. Since the mask main body 1 expands and contracts in the vertical direction via the heel 10, a single mask size can correspond to various face sizes and shapes.

As viruses are discovered one after another, many people take care of the health of people who are exposed to harmful dust in various production facilities and waste treatment facilities, in addition to the use of hay fever. In thinking, the mask of the present invention can be applied to adults and children in one size.

The Example of the mask of this invention is shown and it is the perspective view which looked at the mask of the unfolded state from the surface. It is the perspective view which looked at the mask from the back side same as the above. It is explanatory drawing of the state equipped with the mask same as the above. It is the perspective view which showed the conventional mask and looked at the mask of the expansion | deployment state from the surface. It is the perspective view which looked at the unfolded mask from the back side same as the above.
