JP7514909B2 - Multifunctional sanitary mask - Google Patents

Description

The present invention relates to a sanitary mask that has multiple horizontal pleats on nonwoven fabric, both ends fused together, and ear loops to cover the nose and mouth, and a method for manufacturing the same.

Nonwoven masks are recommended and are used by many people, but they cover most of the face, which can cause problems such as a feeling of pressure, breathlessness, the mask slipping off, and glasses fogging up.

Currently, the same sanitary mask is used to protect against pollen, dust, PM2.5, and viruses, so there is a demand for sanitary masks with more functions.

High-performance sanitary masks are available, but they are expensive.

Patent Publication No. 2009-072522 Patent Publication No. 2015-073890

The aids in the above patent documents seem to be intended to secure space around the mouth, but they come into direct contact with the skin, are unstable, and cause glasses to fog up. This is not only due to gaps around the nose, but is also largely due to the breath passing through the mask filter rising up and fogging up glasses, and cannot be solved by a nose fitter alone. In conventional technology, it is common to wear the bottom end of the mask covering the chin, but this is uncomfortable due to a feeling of pressure, and when wearing a mask when you have a runny nose due to a cold, hay fever, temperature difference allergy, etc., it is troublesome to remove the mask to wipe it off.

The present invention is in the form of a sanitary mask, and has a substrate of a nonwoven fabric that is soft and pleasant to the touch on the surface.
A non-breathable flexible film is laminated to the upper 1/3 of the back surface of the nonwoven mask base material, and a pollen, PM2.5 dust capture filter and water-absorbent nonwoven fabric are fused to the lower end of the laminated part on the lower 2/3. The lower end of the nonwoven mask is folded back and fused about 10 mm. One or more holes or hooks are provided in the fused part. A slit of about 10 mm is provided on the left and right sides of the upper end of the laminated part, which opens up widely when the auxiliary device main body is attached to the nonwoven mask main body, making it easier to attach the auxiliary device main body. A slit may also be provided at the lower end.
Create multiple horizontal pleats in the center of the nonwoven mask base, leave excess material at the top and bottom that is at least half the width of the pleats, fold the top of the excess material over to the back first, then fold the bottom over again to leave an overlap of about 10 mm. Once both ends are fused and the ear straps are fused and fixed, the sanitary mask body is created.

In the present invention, the inner mask is placed inside the main nonwoven mask body, and the base material of the inner mask consists of a single nonwoven nanofiber filter, which is capable of capturing airborne aerosol viruses and can be repeatedly washed and boiled for disinfection, making it hygienic and allowing for long-term use.
Make cuts of about 10 mm on the left and right sides of the upper end of the inner mask base material; one may also make one at the lower end; fold back and fuse the lower end of the inner mask base material by about 10 mm; make one or more holes or hooks in the fused part to hook onto the fastener of the auxiliary device body; make multiple horizontal pleats in the center of the inner mask base material; leave excess parts at the top and bottom that are at least half the width of the pleats; fold back the upper part of the remaining excess part to the back first, then fold back the lower part, leaving an overlap of about 10 mm, and fuse both ends.

The present invention is an auxiliary device that is an accessory to a sanitary mask, and is made of elastic thermoplastic resin.
The elastic band is secured in the best position by providing multiple fasteners on the left and right sides of the lower back. A rubber tube may be placed over the elastic band. The support device body is provided with one or more fasteners for fastening the lower end of the mask.
The curved shape of the bottom view of the main body of the assistive device is sized so that the chin does not come into contact with it.
The device is provided with a fixing device for fixing an absorbent pad for absorbing nasal mucus near the center of the back of the device body.
A protrusion is provided on the upper back of the main body of the aid to prevent the sanitary mask from slipping against the nose.
A recess is provided on the upper front of the main body of the support device. Fasteners for fastening the elastic cord are provided on the left and right sides of the recess.
A guide hole for passing a rubber cord through is provided at the tip of the side of the recess.

The sanitary mask is less likely to slip due to the protrusion 9 on the assistive device of the present invention that comes into contact with the tip of the nose.
The elastic band 12 of the auxiliary tool and the protrusion 9 of the auxiliary tool function to allow the lower part of the sanitary mask body to be shielded above the chin and below the lips, so that the sanitary mask can be worn with the chin exposed, eliminating the feeling of pressure.
By providing multiple elastic strap fasteners for the support device, it is possible to set each device to its own best position.
The elastic band 12 attached to the assistive device pulls up the lips and closes the mouth, which naturally encourages nose breathing.
The lamination 18 of the nonwoven mask significantly reduces fogging of glasses.
The water-absorbing pad 11 attached to the auxiliary device can absorb and process nasal mucus inside the mask.
The recess 8 provided in the support tool allows the mask to flexibly fit around the nose to the shape of the nose, so the area around the nose does not bulge and does not obstruct vision.
The nonwoven fabric mask body 14 is in a bag-like shape, and the entire auxiliary tool is wrapped in the bag-like shape, so that the auxiliary tool does not come into contact with the skin.
The flexible nonwoven fabric used as the base material for the nonwoven mask body serves as the nonwoven fabric base material on both the front and back of the mask body, making it a hygienic mask that is soft to the touch and comfortable to wear.
The inner mask body can be washed and boiled to sterilize repeatedly, so it can be used for a long period of time, making it economical.
In the case of a double filter, the filter in the outer nonwoven mask captures substances larger than 2μ, so the inner mask is less likely to clog and remains in good condition for longer.
By using single and double filters appropriately, it is rational and economical.
