Abstract

PROBLEM TO BE SOLVED: To provide a mask for preventing fogging of glasses, which can effectively reduce or eliminate the fogging of the glasses by reliably closing a gap formed between the mask and the face.SOLUTION: A thin film piece 4 is stuck on an elastic folded part 3 of an upper part of an air-permeable ear hook mask body 1 by an adhesive, a double sided tape or the like. The thin film piece is made of one symmetrical piece folded in two right and left parts. A first thin film piece is brought into intimate contact with the face by expiratory pressure during attachment to eliminate a gap between a mask body and the face and prevent fogging of glasses.

Description

The present invention relates to a mask capable of preventing fogging of glasses.

Normally, the mask covers your nose and mouth and breathes through the mask body, but there is always a gap between the face and the mask, and if you wear glasses, your glasses will be clouded by your breath and you should always wipe your glasses. I had to remove it.

The anti-fogging mask for folding glasses disclosed in Japanese Patent Application Laid-Open No. 2013-75130 of the previous case and the mask of the structure for preventing the gap between the face and the face of other cases can temporarily prevent the fogging of the glasses, but the amount of breath and the face to exhale As a result, the folded part of the mask swells due to the movement of the mask and does not fit the face, and as a result, there is a problem that the glasses leak due to leakage from the gap.

In order to achieve the above-mentioned object, the present invention provides a mask body and a face in accordance with the shape of a nose formed of a wire-like object such as a metal or a shape memory material on the upper part of a mask and a planar mask body formed in three dimensions. It is configured with a structure in which a thin film piece made of a material that does not allow air to pass through or is difficult to pass through is attached to a mask provided with an elastic bent portion that closes the gap between the elastic bent portion so as to hang downward inside the elastic bent portion. Yes. The important point of the present invention is that it combines the synergistic effect of the elastic bending part and the thin film piece, and the structure is simple and the innovative function prevents leakage of the exhalation to the upper part of the glasses. It is a mask.

In the invention according to claim 1, the mask to which the thin film piece for preventing fogging of the glasses is attached is exhaled from the mouth or nose by matching the elastic bent portion attached to prevent the fogging of the glasses of the mask body to the shape of the nose. Once the exhaled air is elastically bent, leakage of the exhalation is minimized, and the first thin film piece is pressed against the face by the pressure of exhalation, and the first thin film piece and the face are in close contact with each other. The most effective place is the combination of the elastic bending part and the first thin film piece, and the synergistic effect is used to maximize the glasses. An effect for preventing fogging can be obtained.

In the invention according to claim 2, the exhaled air exhaled from the mouth and nose once prevents the leakage of the exhalation at the elastic bent portion, and the first thin film piece is pressed against the face by the exhalation pressure so that the exhalation is raised However, if exhalation leaks rarely through the mask fabric, the exhalation of the exhalation from the mask can be prevented by applying a second thin film piece to the fabric of the mask body over the nasal cavity under the elastic fold.

It is sectional drawing of the AA cross section of FIG. FIG. 2 is a perspective view of FIG. 1. It is a front view of the state which affixed the 1st thin film piece on the elastic bending part of a plane mask main body and a brief type mask main body. It is sectional drawing of the BB cross section of FIG.

In FIG. 1, it is made of 4 elastic soft rubber, nylon, polyester, vinyl, etc. on 3 elastic bent parts of the mask composed of 1 3D mask body and 2 ear hooks. Affix the first thin film piece with adhesive or double-sided tape to hang down. The first thin film piece is a bi-folded left and right symmetric one, and the space of 5 is a space between the mask main body and the first thin film piece when the mask is expanded and attached to the face. It is for close contact.

2 is a cross-sectional view taken along the line AA of FIG.

FIG. 3 is a perspective view of FIG. 1. When the mask is spread and attached, a space of 5 is created between the mask main body of 1 and the first thin film piece of 4, and the first thin film piece of 4 is formed by the pressure of exhalation. This is to ensure close contact with the face.

In FIG. 4, a symmetrical first thin film piece 4 is attached to an anti-fogging elastic folding portion 8 attached to a mask composed of 6 plane mask bodies and 7 ear hooks with adhesive or double-sided tape. By attaching the first thin film piece and using a symmetrical one, a gap is created between the mask body and the first thin film piece when the mask is mounted, and the first thin film is caused by the exhalation pressure. This prevents the piece from adhering to the face and exhaling air through the gap between the mask and the face.

6 can prevent exhalation leaking from the gap between the mask and the face in the three-dimensional mask of FIG. 1, but in rare cases, exhalation may leak from the fabric of the mask body 1 and fogging the glasses may be prevented. Therefore, the second thin film piece 9 made of a material that is thin and does not allow air to pass through or difficult to pass through the mask body cloth of the mask of FIG. In this way, the horizontally long strip-like object is attached to the mask with the adhesive or double-sided tape, and the fogging of the glasses due to the leakage of breath from the mask body material can be prevented.

FIG. 8 is a perspective view of FIG.

9 can prevent exhalation leaking from the gap between the mask body and the face in the plane mask of FIG. 4, but in rare cases, exhalation may leak from the cloth of the mask body of 6 and the glasses may be fogged. In order to do so, the second thin film piece 9 made of a thin film-like material that does not allow air to pass or difficult to pass through is directly below the fabric of the mask body of FIG. 4 below the elastic bent portion 8 and below the nasal cavity. It is possible to prevent fogging of the glasses due to leakage of exhaled air from the mask body material by sticking the entire second thin film piece to the mask with an adhesive or double-sided tape, so that it does not become symmetrical .
