Abstract

An object of the present invention is to reduce the fogging of eyeglasses caused by leakage of exhalation from a gap formed between an upper part of the mask and the nose and cheekbones. A thin film piece 30 has moderate flexibility and is provided on an inner upper side portion of a mask main body 10. A central portion of the upper side is joined to the mask main body 10, and upper side edges 31 and 32 are connected to the joint end. When 23 is moved downward 33 and 34 with the center point 23 to adhere to the adhesive portion 21 on the upper side of the mask main body, the middle portion of the lower side of the thin film piece swells. By this swelling, a gap formed between the upper part of the mask, the nose and the cheekbone is closed, and fogging of the glasses due to exhalation from the gap is reduced. [Selection] Figure 1

Description

  The present invention relates to a mask covering a nose and a mouth, which reduces the fogging of glasses due to the exhalation from the upper gap.

  In the conventional general mask, in the mask covering the nose and mouth, there is a problem that the nausea rises from a gap formed between the upper part of the mask, the nose and the cheekbones, and the glasses are clouded by the water vapor of the exhalation.

  Several proposals have been made to reduce or eliminate such fogging of glasses.

  For example, as disclosed in Patent Document 1, a resin or metal plate that is plastically deformed is provided on the upper part of the mask, and this is bent in accordance with the shape of the nose to close the gap.

  Further, as disclosed in, for example, Patent Document 2, there is a technique in which an adhesive substance is provided on an upper part of a mask and is adhered to a nose and a cheek to seal the gap.

  Furthermore, as disclosed in Patent Documents 3 and 4, for example, a sponge-like substance is provided on the top of the mask so as to close the gap.

  Furthermore, as described in Patent Documents 5 and 6, for example, a thin film piece made of a material that does not allow air to pass through or is difficult to pass air is pressed against the cheek so as to close the gap. There is something

  Japanese Laid-Open Patent Publication No. 2006-305279   JP 2006-263172 A   JP 2008-148984 PR   JP 2003-236000 PR   Japanese Laid-Open Patent Publication No. 2007-054270   JP2007-061585

  However, in the case where the plastically deformed resin or metal plate described in Patent Document 1 is provided, it is difficult to bring the upper end of the mask into close contact with the cheek, and the gap cannot be sufficiently closed, and the fogging of the glasses The stop function is insufficient.

  Moreover, what gave the adhesiveness described in the above-mentioned patent document 2 has a preference of a feeling of wearing, and it is thought that the frequency | count of removal | desorption is limited, and it cannot necessarily be said that it is a good method.

  Furthermore, when the mask upper portion described in Patent Documents 3 and 4 is provided with a sponge-like substance, the thickness and volume when not in use are large, and it cannot be said that storage is good.

  In the case where the thin film piece described in Patent Documents 5 and 6 is pressed against the cheek, the thin film piece is flat and does not necessarily close the gap, and the antifogging function of the glasses is sufficient. That's not true.

  The present invention has been made in view of such circumstances, and closes the gap formed between the both sides of the wearer's nose, the cheek portion, and the upper side of the mask, and reduces the fogging of the glasses due to the exhalation from the gap. The purpose is to provide a mask.

The mask according to claim 1, further comprising a cloth-like or sheet-like thin film piece that has a lower air permeability than the mask main body and is moderately flexible inside the upper side of the mask main body that covers the nose and mouth. The mask body is bonded or adhered to the center of the upper side. When the end of the joint or adhesive portion Ru lowers the both end portions of the thin film pieces as a base point planar thin film pieces is inflated state the left and right lower side. In this state, the upper side portion that is not joined or adhered is maintained in a state of being joined or adhered and swollen, and the swelling forms a gap formed by the nose, cheeks, and the upper side of the mask.
As a more preferable configuration, the thin film piece and the mask body are joined at the center of the upper side, and the remaining upper side is adhered when the mask is used. In this configuration, the user forms the nose, cheeks and the upper side of the mask. The degree of swelling can be used in a good state by lowering both ends of the thin film piece according to the size of the gap to be formed.

In the mask of claim 2, the thin film piece is provided on the inner side of the mask main body covering the nose and mouth, and is made of a cloth-like or sheet-like material having lower air permeability than the mask main body and having appropriate flexibility. The lower part of the piece is bonded or adhered to the inside of the upper side of the mask body, and the upper part extends upward from the upper side of the mask body. Bonding or adhesion between the thin film piece and the mask body has a structure in which both ends are lowered , so that when the thin film piece is bent from the upper side of the mask body to the inside and below, the lower side of the thin film piece is bulged. Yes, this bulge closes the gap formed by the nose, cheeks and the upper side of the mask.

The mask of claim 3, the inner mask body upper portion covering the nose and mouth, has a cloth-like or sheet-like thin strip breathability worse than the mask body, and moderately the flexibility, a thin film piece The mask body is bonded or adhered to the upper side of the mask except for the central part. Central and lower gel and flat thin piece of thin piece starting from the edge of the bonding or adhesive portion is inflated state the left and right lower side. In this state, the center part of the upper side which is not bonded or adhered is maintained in a state of being bonded or adhered and swollen, and the swelling forms a gap formed by the nose, cheek and upper side of the mask.

In the present invention, the lower side of the thin film piece provided on the inner upper part of the mask body or the lower side after bending is swollen on the left and right sides of the nose, and when the mask is applied to the mouth and nose, the bulge is formed by the nose, cheeks and the upper side of the mask. This reduces the gaps between the glasses and reduces fogging of the glasses.

  In the present invention, the thickness of the mask during storage is only the thickness of the thin film piece added to the mask body, and the storage volume can be reduced as compared with a method using an elastic body such as a sponge.

  In addition, by making the thin film piece moderately flexible, the effect of restricting the intake air by securing the swelling strength of the thin film piece can be expected.

The back view explaining the solution means in the present invention It is a back view before inflating a thin film piece with the pleated mask which shows the 1st Embodiment of this invention. It is a pleat type mask same as the above, and is a back view when the thin film piece is expanded and used.
