Abstract

To provide a mask assisting tool that is attached to a mask for covering a nose and a mouth and reduces air leak from a gap formed between the top of the mask, the nose, and the cheek bone.SOLUTION: A think film piece 10 that has suitable flexibility is folded with its top folded inward from folding positions 11, 12 into a reverse-U shape, and then both ends 14, 15 are further folded up to 16, 17, with a center point 13 fixed, thereby bulging the bottom center part of the thin film piece. This thin film piece is bonded to the inner top side of a mask main body 30, and the bulging seals the gap between the mask top, the nose, and the cheek bone, reducing the air leak from the gap.SELECTED DRAWING: Figure 6

Description

The present invention relates to an auxiliary tool for reducing nausea from an upper gap in a mask covering the nose and mouth.

In a conventional general mask, in a mask covering the nose and mouth, there is a problem that nausea rises from a gap formed between the upper part of the mask and between the nose and cheekbones, and the water vapor of the nausea causes the glasses to become cloudy.

Several proposals have been made conventionally to reduce or eliminate the fogging of eyeglasses due to the rise of nausea from the gap formed between the upper part of the mask and the nose and cheekbones.

For example, as described in Patent Document 1, there is a case in which a resin or metal plate that is plastically deformed is provided on the upper part of the mask, and the resin or metal plate is bent according to the shape of the nose to close the gap.

Further, for example, as described in Patent Documents 2 and 3, there is a mask provided with a sponge-like substance on the upper part of the mask so as to close the gap.

Further, for example, as described in Patent Documents 4 and 5, a thin film piece made of a thin film-like material that does not allow air to pass through or does not allow air to pass through is pressed against the cheek to close the gap. I have something to plan

Furthermore, as described in Patent Document 6, for example, a thin film piece is provided on the upper part of the mask, and the bulge thereof closes the gap.

Japanese Patent Application Laid-Open No. 2006-305279 Public Relations Japanese Patent Application Laid-Open No. 2008-148984 Japanese Patent Application Laid-Open No. 2003-236000 Japanese Patent Application Laid-Open No. 2007-054270 Public Relations Japanese Patent Application Laid-Open No. 2007-061585 Public Relations Patent No. 6007425

However, with the plastically deformable resin or metal plate described in Patent Document 1, it is difficult to bring the upper end of the mask into close contact with the cheek, and the gap cannot be sufficiently closed, causing the glasses to become cloudy. The stopping function is insufficient.

Further, the mask provided with the sponge-like substance on the upper part of the mask described in Patent Documents 2 and 3 has a large thickness and volume when not in use, and cannot be said to be good for storage.

In the case where the thin film pieces described in Patent Documents 4 and 5 are pressed against the cheeks, the thin film pieces are flat and do not necessarily close the gaps, and the anti-fog function of the glasses is sufficient. I can't say that.

Further, in the thin film piece described in Patent Document 6 described above, the joint with the mask is made of three straight lines, and the thin film piece is bent at two vertices, so that it is somewhat difficult to manufacture and is suitable for mass production. It is considered unsuitable.

The present invention has been made in view of such circumstances, and is a mask aid that closes the gaps formed between both sides of the wearer's nose, cheeks, and the upper side of the mask, and reduces nausea from the gaps. The purpose is to easily manufacture and provide masks.

The mask aid according to claim 1 is attached to the inside of the upper part of the mask body that covers the nose and mouth, and a thin film piece made of a material having poorer breathability and moderate flexibility than the mask body has an upper part. The gap formed between the nose, cheeks, and the upper side of the mask due to the bulge of the thin film piece that occurs when the thin film piece is bent inward in an inverted U shape and then straight from the center to the end and the center is the apex and both ends are lowered downward. It is characterized by closing.

The mask according to claim 2 is characterized in that the mask auxiliary tool according to claim 1 is attached or integrated.

In the present invention, when used by attaching to the upper part of the mask body, the bulge on the lower side of one thin film reduces the gap formed between the nose, cheeks and the upper side of the mask, reduces nausea from this gap, and reduces fogging of the glasses. be able to.

In the present invention, since the thin film piece has one bending apex and the bonding or adhesion with the mask may be linear, it can be easily manufactured and provided at low cost.

In the present invention, the thickness at the time of storage is only the thickness of the thin film piece or the thickness of the bent thin film piece, and the storage volume can be reduced as compared with the method using an elastic body such as a sponge, and the present invention is attached to the mask. Even when stored in a state, the storage volume is smaller than when an elastic body such as a sponge is used.

It is a developed view of the thin film piece which is an auxiliary tool which shows embodiment of this invention. Same as above It is a view seen from the face side in a state where the thin film piece is bent into an inverted U shape. Same as above It is a view seen from the face side with the thin film piece inflated. It is a view of the same above state from above. It is the figure of the state which attached the auxiliary tool of this invention to a pleated mask. It is a figure which shows the arrangement of a thin film piece and a mask.

In order to maintain the state in which the thin film piece is bent into an inverted U shape, it is preferable to join or adhere at the center of the thin film piece.

In order to maintain the state in which both ends of the thin film piece are bent deeper than the state in which the thin film piece is bent in an inverted U shape and to secure stable swelling, it is preferable to join or adhere the vicinity of both ends of the thin film piece.

When an elastic or tense reinforcing material is attached to the thin film piece, the degree of bending of the thin film piece can be dealt with in different states at the top and valley of the nose depending on the partial presence / absence strength of the reinforcing material.

The time for joining or adhering the thin film piece and the mask may be before or after bending the thin film piece.
