Description

In the present invention, the upper and lower ends of the long holes through the ear hook of the auxiliary mask are dropped into the drop recesses that form the symmetrical hook shape provided on the upper and lower sides near the boundary between the mask body and the ear hook. By inserting the ear hook part of the mask body into the long hole of the ear hook part of the auxiliary mask alternately inside and outside and superimposing it, a part of the extension part is tightened and fixed, so that the mask body and the auxiliary mask do not shift. Regarding double masks that can be overlaid .

Conventionally, the effect of wearing a cloth (gauze) mask that is generally used is said to be effective in suppressing the spread of droplets scattered by pollen in the outside world or coughing or sneezing of others, but it floats in the air. It is said that it is not possible to sufficiently capture the sneezing virus bacteria, and reuse by washing is not recommended from a hygienic point of view because it varies depending on the user's environment, but rather it is not recommended by some experts. It has been pointed out that there are many hygienic effects.

The hygiene / infection prevention effect required for conventional cloth (gauze) masks and non-woven fabric masks is to prevent the spread of bacteria and viruses contained in the pollen of the outside world and the droplets such as coughing and sneezing of others.
Especially in the case of cloth (gauze) masks, as is often said in comparison between baseball fields and balls, the gaps between the fibers of the cloth are larger than the size of the virus (about 0.1 micrometer), and most cloth (gauze) masks. While it is said to have no preventive effect, it has been reported that the virus that exercises brown while passing through the fiber net of the cloth has a certain capture effect.

Based on the efficacy of such a conventional mask effect, various masks are provided according to the environment in which the mask is used.
For example, a cloth (gauze) mask is provided for the purpose of preventing the scattering of saliva particles and viruses contained in the droplets scattered by pollen of the outside world or coughing or sneezing of another person.
By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Sciences of the University of Tokyo, the permeability of the scattered virus in the experiment using the mannequin and the virus in the room where the virus does not leak is as high as 60 to 80%, and the content of the experiment is the American scientific journal " It is published in the electronic version of "msphere".

Further, the non-woven fabric mask is provided for the purpose of preventing dust and Brownian motion viruses generated during manufacturing and working in factories and the like in the gaps between the fibers of the non-woven fabric.
It has been reported that the transmittance of the scattered virus in experiments using mannequins and viruses is around 50%.

On the other hand, N95 masks are used as a source of infectious substances such as fine droplets and viruses (about 0.1 micrometer) floating in the air, coughing, squeezing, blood, secretions, saliva, sweat, and vomitus generated from patients. It is provided for the purpose of preventing harmful particles such as fine particles having a particle diameter of 2.5 micrometers or less floating in the atmosphere, such as a fine particle substance “PM2.5”, in addition to water, chemicals, dust and the like.
By the way, by Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, the transmittance of the scattered virus in an experiment using a mannequin and a virus in a room that does not leak the virus is as low as 10 to 20%.

However, none of the above masks can eliminate the gap between the mask and the face, and in reality, due to the structure of the mask, a virus (about 0.1 micrometer) can be seen between the mask and the face. Many researchers argue that the mask has almost no protective effect because it has a structure that allows the intrusion of fine particle substances such as "PM2.5".

Conventionally, masks that solve the above problems have been proposed.
For example, a "mask replacement gauze" (Patent Document 1) has been proposed, which enhances the moisturizing effect of the user's own breathing and makes it a throat-friendly mask by layering it on an existing non-woven fabric mask, and in some cases gives a fashionable feeling. It is a known technology.

However, the proposal for the "mask replacement gauze" is to attach the left and right gauze to the mask that covers the mouth and nose when the face is worn, and to attach the cloth gauze to the side in contact with the face. A replacement gauze that is slightly larger than the mask and has a vertically long insertion hole through which the ear hooks are inserted alternately, and a gauze that covers the mouth and nose hole is attached to the insertion hole by passing the left and right ear hooks over the mask. It is a proposal, and the proposal is merely a proposal to facilitate the replacement of the mask replacement gauze, and further, the replacement gauze is twisted and turned over by the insertion hole being close to the side end face of the mask. There were structural problems such as misalignment and weakening.

In addition, a "hygiene mask" that can reduce the unpleasant odor and dampness felt by the user while fulfilling the purpose of hygiene or protection, and further suppress the growth of bacteria and viruses while having breathability (Patent Document 2). ) Has been proposed and has become a known technique.

However, the proposed "sanitary mask" is a sanitary mask made of a non-woven fabric, which has a first non-woven fabric and a second non-woven fabric, and the first non-woven fabric includes a second non-woven fabric which is laminated and fixed. With the proposal of a sanitary mask that can be changed from the first use state in which the second non-woven fabric is fixed to the first non-woven fabric to the second use state in which the second non-woven fabric is turned over and removed from the first non-woven fabric. Therefore, the proposal was merely a proposal provided with a means for fixing the second non-woven fabric to the first non-woven fabric and a means for turning the non-woven fabric.

Further, a "sanitary mask and a filter for a sanitary mask" (Patent Document 3), in which the filter can be easily replaced and the filter does not easily move from the mask body, has been proposed and is a known technique.

However, the proposal of the "sanitary mask and filter for sanitary mask" has a pair of ear hooks, a mask body formed in a three-dimensional shape whose central portion protrudes forward, and a pair of ear hooks. Instead, it is provided with a filter whose central part is formed in a three-dimensional shape protruding forward along the three-dimensional shape of the mask body and is arranged along the inner surface of the mask body, and the filter extends along the upper side thereof. And a proposal for a sanitary mask having an elongated core that deforms along the shape of the user's nose, the proposal simply providing means for facilitating filter replacement. It was just a proposal.

The conventional double mask described above is merely a proposal to facilitate the replacement of the gauze and filter attached to the inside of the mask body, and is effective as a mask for preventing coronavirus droplet infection. As the infection spreads pandemicly, it is becoming mandatory to wear masks worldwide, and it goes without saying that general consumers also have an infection prevention function for clothing and TPO. There is also an increasing need to provide fashionable masks that match.

The applicant, of course, has a conventional mask droplet infection prevention function, and proposes a "double mask" that can meet the needs of new fashionable masks. According to the announcement by the US CDC Center, the virus blocking rate has increased from 40% to 92%, and the exhalation rate from the periphery of the mask has increased from 73% to 50%. It has also been reported that the degree of adhesion has increased.
In addition, depending on the national character of the world, even foreigners who feel guilty about hiding their faces can expect the effect of increasing the wearing rate by using a double mask of different colors.

The applicant has made this in view of the above social background, and the double mask of the present invention forms a symmetrical hook shape provided on the upper and lower sides near the boundary between the mask body and the ear hook. The upper and lower ends of the long holes for the ear hooks of the auxiliary mask are dropped into the recesses, and the ear hooks of the mask body are alternately inserted into the long holes for the ear hooks of the auxiliary mask and overlapped. We have developed a double mask in which the mask body and the auxiliary mask can be overlapped without misalignment by tightening and fixing a part of the extension part, which led to the proposal of the "double mask" in the present invention. ..
