Description

The present invention relates to a face cover to be worn as a set with a sanitary mask.

With the conventional general integrated hygiene mask, a gap is generated between the mask body as a ventilation filter and the face when worn, and it is not possible to prevent the intrusion and outflow of foreign matter. Proposals for solving such problems have been made conventionally.

For example, in the case described in Patent Document 1, the gap at the upper part of the nose is closed by a non-breathable elastic bent portion that is bent at the upper end edge of the mask body.

However, the elastically bent piece does not come into close contact with the face and is easily displaced, so that the gap cannot be closed and the flow of exhaled breath or the like cannot be prevented.

Further, the mask in Patent Document 2 has the functions of a curvature maintaining body, a shape maintaining body, and a gel layer, and has a structure in which the mask is brought into close contact with the face.

The problem with the above mask is that the gel layer for facial adhesion does not adhere due to drying. As a solution, it has a function to replenish water with a dropper, but it is difficult to keep water at all times, and it is unlikely that you are always in that environment.

Further, the mask proposed in Patent Document 3 has a double structure, one is made of a highly breathable non-woven fabric, and the other is a highly elastic inner sheet having an opening for inserting the nose and mouth to prevent uneven plastic distribution. It is a proposal to provide it to eliminate the gap.

The problem of the above proposal is to aim for outside air breathing and exhaust with only the outer layer, but dust pollen, viruses, etc. cannot be completely prevented, and a band-shaped plastic uneven distribution is provided in the center of the upper edge to prevent gaps, but slip prevention is prevented. It is unlikely that it will serve its purpose.

Hygiene masks that are currently in widespread use have been devised in various ways to close the gaps, but they cannot adhere to the unevenness of the face and exhaled breath remains to occur, making it impossible to utilize the high-performance filter effect. .. Originally, a hygiene mask is very important not only for protection of others but also for self-defense, such as preventing exhaust from gaps such as droplet diffusion prevention and preventing invasion of invading viruses and the like through gaps. Therefore, there is a need for a breath leak prevention mask with higher adhesion, and there is an urgent need to develop a complete breath leak prevention mask that can be worn correctly in closed spaces such as commuter trains and theater viewing.

Based on the content of claim 1, the present invention proposes a face cover for a hygiene mask made of adhesive low-hardness silicone to be attached under the sanitary mask instead of the conventional integrated sanitary mask, and attempts to solve the above-mentioned drawbacks. is there. Further, as an example, the outer circumference is formed in a thin fold shape, the periphery of the central opening is projected, a nose guard that contacts both sides of the nose in the upper center is provided, and an exhalation leak guard fold is provided inside the main body for further adhesion. Improve. The present invention transforms the conventional notion that sanitary masks are integrated.

As described above, according to the content of claim 1, the present invention eliminates the gap between the faces due to the self-adhesion and shape restoration force of the low-hardness silicone, and breathes only at the filter part of the sanitary mask that overlaps the central opening of the face cover. And, it achieves the expectation that the flow of exhaled breath other than that is completely blocked.

Low-hardness silicone is a silicone rubber with a temperature of 10 degrees or less, which is harmless and odorless to the skin, and can be used over and over again by washing sweat and sebum stains with soap or a weakly acidic detergent, and maintains its shape and adhesiveness. it can. Silicone is a popular material and can be mass-produced at low cost. If the hardness exceeds 10 degrees, the adhesion is lowered and the object of the present invention cannot be achieved.

First, in the first embodiment shown in FIGS. 1 to 2, reference numeral 1 generally indicates the face cover of the present invention, all of which are integrally molded with low-hardness silicone, and the sanitary mask 2 is superposed on the face cover. It is intended to be used.

In the first embodiment shown in FIG. 2, in addition to the self-adhesion of the low-hardness silicone material, the same material provided all around the main body wraps around the folds to further enhance the adhesion effect.

The nose guard 4 shown in FIG. 2 has a structure in which it abuts on both side surfaces of the nose, and is crimped together with the chin portion 8 shown in the wearing stage FIG. 2 to be brought into close contact with the wearer's face. At the same time, the outer peripheral folds are also crimped and the sanitary mask is placed on the main body to obtain the mounting diagram of FIG.

FIG. 3 is a schematic side view of the face cover main body and the sanitary mask 2 attached in the first embodiment shown in FIG. If the point c that intersects the central opening upper point a and the central opening lower point b with the same length is designated as the symbol c, the length of the point c that intersects the central opening upper point a and the point c that intersects the central opening lower point b The length is the same and the tension is the same, but the original position of the ear hook is the upper part d of the ear and the lower part e of the ear, and the lengths of both are different. Therefore, it can be expected that the lower part b of the central opening is projected a lot to eliminate the disagreement of tension, increase the degree of adhesion, and prevent exhaled breath leakage.

In the first embodiment shown in FIG. 4, the flexibility of the material is utilized by sharpening the entire circumference 9 of the tip of the protrusion of the central opening as shown in the cross-sectional view taken along the line AA of the central opening 6, so that the mask 2 and the sanitary mask 2 are used. The effect of increasing adhesion can be expected.
