Abstract

To provide a mask for closing a gap of a mask upper side part contacting the nose and cheeks, for preventing a leak of expiration and for preventing spectacles from fogging in a mask covering the mouth and nose of a user.SOLUTION: A mask of the present invention is a mask in which an air-nonpermeable thin film piece 3 with an angle downward and flexible suitably is adhered to inside of an upper side part of a mask body 1 with an adhesion line 4 and an adhesion line 5 with both ends lowered from an upper side middle. In this state, the thin film piece 3 is formed so that when the mask body 1 is worn folded upward before wearing, it is inclined more inward than the mask body 1 at an acute angle and the angled middle part is compressed by a pad of spectacles to contact and cover the nose and cheeks firmly.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mask that covers the mouth and nose of a person.

  The conventional mask has a problem that the exhalation leaks from the gap between the upper side of the mask in contact with the nose and the cheek and the glasses become cloudy.

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

  For example, as described in Patent Document 1, there is a device in which a gap closing sheet with a shape holding member that deforms in accordance with the shape of a face is provided inside a mask upper side to close the gap.

  For example, as described in Patent Document 2, there is one in which a resin or metal plate which is plastically deformed is provided on the upper side of the mask and this is bent according to the shape of the nose or cheek to close the gap. .

  For example, as described in Patent Document 3, there is a device in which an adhesive substance is provided on the upper side of the mask and the gap is sealed by making the mask stick to the nose and cheek.

  For example, as described in Patent Documents 4 and 5, there are some which are provided with a sponge-like substance on the upper side of the mask and intended to close the gap.

  For example, as described in Patent Document 6, the upper side of the mask is fixed to the inner side of a thin, thin, air-impermeable or thin-air-permeable thin film piece, and the air pressure of exhalation exhaled from the mouth and nose is used. There is a device for closing the gap by pressing the thin film piece against the face.

  For example, as described in Patent Document 7, a thin film piece is provided inside the upper side of the mask, and both sides of the thin film piece are joined below the center to expand the middle of the thin film piece, thereby closing the gap. There is something I'm trying to do.

JP 2017-203221 Japanese Patent Application Publication No. 2006-305279 Japanese Patent Application Laid-Open No. 2006-263172 Patent document 1: JP 2008-148984 Japanese Patent Application Publication No. 2003-236000 JP 2013-075130 Japanese Patent Application Laid-Open No. 2016-188453

  However, it is difficult to continuously keep the sheet in close contact with the nose and cheeks in the case where the gap closing sheet with the shape holding member which deforms in accordance with the face shape described in Patent Document 1 is provided inside the upper side of the mask. Anti-fog function is insufficient.

  Further, in the case where a resin or metal plate which is plastically deformed is provided on the upper side of the mask described in Patent Document 2 described above, it is difficult to keep the upper side of the mask closely in contact with the nose and cheeks. It is not enough.

  Further, in the case where the upper side portion of the mask is provided with an adhesive substance and the upper side portion of the mask is made to adhere to the nose and cheeks described in Patent Document 3 described above, adhesion may be difficult depending on the skin conditions such as sweat and makeup.

  Moreover, what provided sponge-like substance in the mask upper side part described in the said patent document 4, 5 takes storage volume too thick with the thickness of a sponge-like substance.

  Also, fix the upper side of the thin film-like, air-impermeable or air-impermeable thin film piece inside the upper side of the mask described in Patent Document 6 above, and use the air pressure of the exhaled air exhaled from the mouth and nose. When the thin film piece is pressed against the face, the air pressure of exhalation causes a gap to be created between the thin film piece, the nose and the cheek.

  Further, a thin film piece is provided on the inner side of the upper side of the mask described in Patent Document 7 mentioned above, and both sides of the thin film piece are joined below the center to expand the stem of the thin film piece. Since the stem of the membrane membrane is inflated so as to form wrinkles, it is difficult to firmly attach the membrane strip to the nose and cheeks so that the anti-fog function of the glasses is insufficient.

  The present invention has been made in view of such circumstances, and aims to provide a mask which closes the gap between the nose and cheek formed on the upper side of the mask when worn and reduces the fogging of the glasses due to exhalation leaking from the gap. Do.

  In the mask of the present invention, a thin, moderately flexible, air-permeable thin film piece 3 is adhered to the inside of the upper side portion of the mask main body 1 with the adhesion line 4 with both ends lowered from the center of the upper side. It is a mask characterized by In this state, when the thin film piece 3 is folded upward before mounting and the mask main body 1 is mounted, the thin film piece 3 inclines inward at an acute angle inside the mask main body 1, and the central part of the mountain shape is suppressed by the pad of glasses and tightly covers the nose and cheek Formed as.

  In the above mask, when the mask of the present invention is attached, the thin film piece 3 is covered with the same coating as the mask main body 1 on a thin film which is appropriately flexible and impermeable so as to have the same touch as the mask main body.

  According to the present invention, the thin film piece 3 is inward of the mask main body 1 when the mask main body 1 is attached by bending the upper side along the adhesive line 4 of the thin film piece 3 joined to the upper side of the mask and hooking the ear hook 2. By tilting at an acute angle and closing the gap between the nose and the cheek, it is possible to prevent fogging due to exhalation of the glasses.

  According to the present invention, only the thickness of the thin film piece 3 is added to the mask main body 1, and the storage volume is reduced as compared with the method using the sponge-like substance.

  According to the present invention, the thin film piece 3 is impermeable and covered with the same film as the mask main body 1 with appropriate flexibility, so that the same skin feel as the mask main body 1 can be obtained, and discomfort in wearing can be reduced.

  According to the present invention, when the glasses are not used, the thin film piece 3 can be used as the shape of the mask main body 1 as it is.

  It is a mask back view showing an embodiment of Claim 1.   It is a side view of a mask same as the above.   FIG. 7 is a back view of the thin film piece of the mask of the present invention when it is used by being bent upward   It is a side view of a mask same as the above.   The side view which shows the state equipped with the mask of this invention.

  According to the mask of the present invention, as shown in FIG. 1 and FIG. 2, along the adhesive line 4 in which the thin film piece 3 with appropriate flexibility and air permeability is lowered from the center of the upper side inside the upper side of the mask body 1. It is attached and attached.

  The thin film piece 3 of the mask according to the invention is coated on both sides with the same film as the mask body 1 with an appropriately flexible and air-permeable thin film.

  As shown in FIG. 3 and FIG. 4 and FIG. 5, the thin film piece 3 of the mask of the present invention is bent upward along the bonding line 4 before mounting, and the ear strap 2 is hooked on the ear and the mask body 1 is mounted. It is inclined at an acute angle inside the main body 1, and the central portion of the thin film piece 3 is shaped so as to be tightly held so as to firmly cover the nose and cheeks while being suppressed by the putter of the glasses.
