Description

According to the present invention, by taking out the ear straps of the mask main body from the cut slits of the auxiliary mask and overlapping them, the mask main body and the auxiliary mask can be superimposed without being misaligned, and viruses can be prevented from entering from the sides of the mask main body. To provide a double mask capable of being blocked and preventing double exposure of ear straps.

Conventionally, the effect of wearing a commonly used cloth (gauze) mask is said to be effective in suppressing the spread of pollen from the outside world and droplets scattered by other people's coughs and sneezes. It is said that it is not possible to sufficiently capture the viral bacteria that cause it, and furthermore, reuse by washing varies depending on the user's environment, so it is not recommended from a hygienic point of view. It has been pointed out that many sanitary hazards are involved.

The sanitary and anti-infection effects required of conventional cloth (gauze) masks and non-woven masks are to prevent the spread of bacteria and viruses contained in pollen in the outside world and droplets such as coughs and sneezes of others.
In particular, in the case of cloth (gauze) masks, as is often said in comparisons between baseball fields and balls, the gaps between the fibers of the cloth are larger than the size of the virus (about 0.1 micrometers), and most cloth (gauze) masks Although it is said to have no preventive effect, it has been reported that viruses that undergo Brownian motion while passing through the fiber net of cloth have a certain trapping effect.

Based on such conventional mask effects, various masks have been provided according to the environment in which they are used.
For example, cloth (gauze) masks are provided for the purpose of preventing scattering of saliva particles and viruses contained in droplets scattered by outside pollen, coughs and sneezes of others.
By the way, Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, conducted an experiment using mannequins and viruses in a room that did not leak viruses, and the transmission rate of the scattering virus was as high as 60 to 80%. It is published in the electronic version of "msphere".

In addition, non-woven fabric masks are provided for the purpose of preventing dust generated during manufacturing and work in factories and viruses that perform Brownian movement in the gaps between fibers of non-woven fabric.
It has been reported that the transmittance of flying viruses in experiments using mannequins and viruses is around 50%.

On the other hand, N95 masks are not suitable for fine droplets and viruses (about 0.1 micrometers) floating in the air, and infectious agents such as coughs, sneezes, blood, secretions, saliva, sweat, and vomit generated by patients. , water, chemicals, dust, etc., as well as particulate matter "PM2.5" and other harmful particles such as particles with a particle size of 2.5 micrometers or less floating in the atmosphere.
Incidentally, in an experiment conducted by Professor Yoshihiro Kawaoka of the Institute of Medical Science, the University of Tokyo, using mannequins and viruses in a room that does not leak viruses, the transmission rate of the scattering virus is as low as 10-20%.

However, none of the above masks can eliminate the gap between the mask and the face. In reality, due to the structure of the mask, viruses (about 0.1 micrometers) and Many researchers argue that masks have little protective effect because they are structured to allow fine particles such as PM2.5 to enter.

Conventionally, proposals have been made for masks that solve the above problems.
For example, a ``mask replacement gauze'' (Patent Document 1) has been proposed that can be used over an existing non-woven mask to increase the moisturizing effect of the user's own breathing, making it a gentle mask for the throat, and in some cases, giving it a fashionable look. It is a well-known technique.

However, the proposal for "mask replacement gauze" is based on the fact that in a mask that has ear straps attached to the left and right sides and covers the mouth and nostrils when worn on the face, the left and right gauze is attached to the side that contacts the face. This is a proposal for a replaceable gauze that is slightly larger than a mask and has vertical insertion holes through which ear straps are inserted, and gauze that covers the mouth and nostrils by passing the left and right ear straps through the insertion holes is replaceable. This proposal is merely a proposal for facilitating replacement of the replacement gauze of the mask, and furthermore, the replacement gauze is twisted, turned up, or displaced due to the insertion hole being close to the side end surface of the mask. , and had structural problems such as weakening.

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

However, the proposed "sanitary mask" is a sanitary mask made of non-woven fabric, comprising a first non-woven fabric and a second non-woven fabric, the first non-woven fabric having the second non-woven fabric layered and fixed. , a sanitary mask that can be changed from a first state of use in which the second nonwoven fabric is fixed to the first nonwoven fabric to a second state of use in which the second nonwoven fabric is removed from the first nonwoven fabric. Therefore, the proposal merely provided means for fixing the second nonwoven fabric to the first nonwoven fabric and means for turning over the nonwoven fabric.

In addition, a "sanitary mask and sanitary mask filter" (Patent Literature 3) has been proposed and is a well-known technology, in which the filter can be easily replaced and the filter does not easily move from the mask body.

However, the proposed "sanitary mask and sanitary mask filter" has a mask body formed into a three-dimensional shape having a pair of ear hooks, the central part of which protrudes forward, and a pair of ear hooks. a filter formed along the three-dimensional shape of the mask body so that its central portion protrudes forward and is arranged along the inner surface of the mask body, the filter extending along the upper side thereof. and a sanitary mask having an elongated core that conforms to the shape of the user's nose, the proposal simply comprising means for facilitating replacement of the filter. It was nothing more than a proposal.

The conventional double mask described above is only a proposal to facilitate the exchange of gauze and filters attached to the inside of the mask body, and it is effective as a mask for preventing droplet infection of coronavirus. , With the spread of pandemic infections, the wearing of masks is becoming obligatory worldwide. There is also an increasing need to provide fashionable masks that match.

The applicant proposes a "double mask" that can meet the needs of a new fashionable mask, not to mention that it has the droplet infection prevention function of the conventional mask. According to the US CDC Center's announcement, by overlapping, an experimental report was made that the virus blocking rate was increased from 40% to 92%, and the exhalation leakage rate from the side of the mask was increased from 73% to 50%. It is also reported that the degree of adhesion decreased and the degree of adhesion 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 double masks of different colors.

The applicant of the present invention was made in view of the above social background, and the double mask of the present invention is a mask body and a mask body by taking out the ear straps of the mask body from the cut slits of the auxiliary mask and overlapping them. We have developed a double mask that allows auxiliary masks to be superimposed without slipping, prevents viruses from entering from the side of the mask body, and does not expose the ear straps twice. This leads to the proposal of the "double mask" in the invention.
