SOLUTION: The mask is used in a state where the wearer's nose and mouth are covered with a sheet-like material through which gas can pass, and the sheet is substantially horizontal on both sides of the nose and the stepped portion of the cheek. It is characterized in that an inwardly folded portion 7 is formed along a line 6 in the direction. [Selection diagram] Fig. 1

Description

The present invention relates to a so-called mask that covers a person's mouth and nostrils to limit the diffusion of exhaled breath, and aims to reduce the leakage of exhaled air from the gap caused by the step between the nose and cheeks around the bottom of the eyes. Is.

The mask made of sheet-like material does not spread the exhaled breath that may contain bacteria discharged from the nose and mouth, and carelessly removes harmful fine dust such as external dust and pollen. It is used for the purpose of not inhaling into.
The evaluation of its performance is mainly based on the breathability of the sheet material itself and the blocking property of bacteria, etc., but what should not be overlooked is how to reduce the gap between the face and the sheet. No matter how high the performance of the sheet material is used, if there is a slight gap, the performance will be greatly impaired. It is an object of the present invention to reduce the gap, which is an important point for the mask.
Introduction of reference products to replace non-patent documents

Some commercially available masks add a wire-like flexible material to the upper edge of the mask in order to reduce this gap, and try to match the mask with the unevenness of the face. However, while this method can be easily adjusted by an individual with a fingertip or the like, it can only be adjusted fairly roughly, and the effect of reducing leakage is limited. Significant amounts of exhaled breath leaks have been observed in cigarette smoke experiments, as evidenced by cloudy eyeglasses when wearing masks in cold weather and in the rain, causing dislike of wearing masks. ..

In addition, there are so-called gas masks that are manufactured to completely match the shape of the face and have cushion members added to them, but they are expensive and stressful during use, so they are generally used. Not suitable for. With commercially available masks, masks made integrally from materials do not have a so-called string length adjustment function, and the mounting pressure cannot be adjusted. Due to this, it may not be possible to sufficiently prevent the leakage of exhaled breath.

The main purpose of the present invention is, of course, to reduce the leakage of exhaled breath between the mask and the face, but if it becomes expensive, it cannot be widely disseminated to the general public. In addition, if the stress during use is large, so-called nose masks and chin-hanging mosques will be increased in the end, and the effect of the mask cannot be expected.

The big point that the user evaluates the comfort of wearing the mask will be the cloudiness of the glasses. On the contrary, it is often the case that the mask is removed because the glasses become cloudy. In this respect, especially when it comes to anti-virus measures, it may lead to the cause of an extremely dangerous state, so reducing the stress of the user, in other words, preventing fogging of the glasses is one of the major indicators.

Further, the purpose of the present invention is to improve the function of the mask, and if it is expensive, it does not meet the original purpose. It is an object of the present invention to achieve both the above-mentioned requirements for highly advanced functions and the fact that they are inexpensive in terms of cost.

Masks made of gauze or thin non-woven fabric cannot be freely shaped, but foamed urethane or sheet-shaped chemical products can be punched into any shape. This mask is a mask with a structure that uses the elasticity of the material to close the gap and prevent the leakage of exhaled breath from this part by weaving the parts corresponding to both sides of the nose under the eyes when wearing a normal mask. is there.

On the contrary, this type of mask cannot adjust the length of the so-called string, so the mounting pressure cannot be optimized. In order to solve this problem, it can be easily dealt with by adding a plurality of U-shaped notches to the ear hook holes.

As is clear from the above explanation, the mask of the present invention has an extremely simple structure that prevents human exhaled breath from splashing through the gap between the nose and cheeks, and prevents fogging of the glasses, thereby reducing stress during wearing. However, it is possible to prevent dangerous acts such as a nose mask and a chin mask. Moreover, there is no factor of increasing the cost of the mask itself, and it is widely used. Much effort is spoiled from the slightest carelessness in preventing viral infections. Its social and economic benefits are immeasurable because it can prevent such causative factors.

FIG. 1 is a plan view showing the shape of an embodiment of the mask cover of the present invention. FIG. 2 is a side view of the mask cover of the present invention when it is attached to a person according to an embodiment.

The present invention is an extremely rational technique for solving the above problems, and the means thereof is extremely simple. The structure will be described below together with the above figure.
The main body 1 made of a soft sheet-like material having elasticity that allows gas to permeate through minute gaps is joined at the central portion 5 as a symmetrical shape so as to match the shape of the face three-dimensionally when worn. It is formed. 2 is an ear hook hole for hanging on the ear. This state is similar to a normal mask on the market. The difference is that a notch 3 is provided in the center of the upper part and notches 4 are provided at symmetrical positions on the left and right sides of the notch 3, and the folded-back portion 7 is folded inward along a line 6 connecting the low points of the notches 3 and 4. .. By doing so, the gap between the wearer's nose and the cheeks under the eyes on both sides can be closed by the folded-back portion 7 with the elasticity of the material of the main body 1. Even if the width and length of the folded-back portion 7 are changed from the shape shown in the figure, the gist of the present invention is not impaired. Further, a plurality of horizontal U-shaped notches 9 are provided in the vicinity of the ear hook holes.

There are some cases where the folded-back portion 7 is formed of another foamable material or the like and attached with an adhesive, an adhesive or the like, but there is a problem in selecting the elasticity and airtightness of the material, and the leakage of exhaled breath is effective. I haven't been able to prevent it. In addition, there is a structure in which a metal wire or the like is sewn in, but the shape formed by bending the wire with a finger by the wearer is not necessarily suitable for the shape of the wearer's face and achieves the purpose. Not done. Furthermore, it is inferior to the present invention in many points such as cost increase due to the troublesomeness of attaching another material and handling at the time of reuse such as washing, and the superiority of the present invention does not change.

In addition, the lower part 8 that hits the wearer's chin at the central part 5 that connects the left and right materials is usually curved and joined so as to wrap the jaw, but this is because the wearer talks with his mouth. When it is opened and closed, the mask mounting position is pulled downward and moved from the regular position. However, there is no function to return it to its original position, so if you want to return it to its original position, you need to make corrections with your hands. In order to prevent such a situation, it is necessary to make the joint shape of the lower portion 8 linear. It is a relatively chewy (not too soft) material, and if there is an appropriate wearing pressure, it will not cause misalignment or exhalation leakage even if there is a sliding movement of the jaw.

Further, the plurality of horizontal U-shaped notches 9 can be arbitrarily selected and listened to. As a result, the wearing pressure can be optimized, the leakage of exhaled breath can be minimized within a stress-free range, and the cost does not increase.

As is clear from the above explanation, the mask of the present invention is not only simple in structure, but also accurately prevents the leakage of exhaled breath, and is dangerous such as a nose mask and a chin mask caused by the stress of clouding the wearer's glasses. It can prevent actions, prevent the cost of the mask itself from increasing, and facilitate handling when it is reused, and its social and economic effects are extremely remarkable.
