Description

  The present invention relates to an anti-fogging mask for glasses and prevention of inflow of pollen and dust.

  Normally, the mask covers the nose and mouth and breathes through the mask body, but there is a dent between the nose and the cheek surface, so when wearing the mask there is a gap near the back of the nose and exhaled from the gap As a result, there is a problem that the glasses must become cloudy and the work or conversation must be stopped and the glasses must be wiped, and pollen, dust or the like flows from the gaps to reduce the original function of the mask.

  In order to prevent this, a hardware was attached to the upper part of the mask body, and the hardware was fitted to the shape of the nose to eliminate the gap, or a flexible object such as a sponge was attached to eliminate the gap near the back of the nose. Talking with a mask, breathing, or moving your face, the shape does not match the shape of the face, leaving a gap little by little, and exhalation leaks and the glasses cloud.

  There exists what was disclosed by patent document 1 as invention for solving such a problem. As shown in FIG. 1 of this document, the mask of this device eliminates a gap near the back of the nose by a thin film-like band 2 so that exhaled breath and sucked air do not leak from the vicinity of the back of the nose. Moreover, what was disclosed in Patent Document 2 prevents exhaled exhaled air from leaking out from the upper part by an exhalation rising blocking cloth 4 as shown in FIG.

Japanese Patent Application No. 11-177591 Japanese Utility Model Publication No. 2-36301

  A general mask covers the nose and mouth and breathes through the mask body, but there is a dent between the nose and the cheek surface, so when wearing the mask there is a gap near the back of the nose. Exhalation leaked from the gap, and the glasses exhaled by the leaked exhalation, and the inflow of outside air and pollen and dust that flowed in along with the outside air could not be prevented.

  The shape and size of the nose varies from person to person, and the shape of the gap formed near the back of the nose varies depending on the position where the mask is worn. For example, if the upper edge of the mask is close to the nose tip, the gap that can be formed near the back of the nose will be more complicated, and if it is close to the nose root, the shape will be simpler. It was difficult and the position to wear a mask was limited.

  The mask described in Patent Document 1 has a structure in which the thin film-like band protruding upward from the mask body is pressed by the lower edge of the spectacle frame or the spectacle lens. There is a sense of discomfort. Usually, there is a gap between the spectacle frame or the spectacle lens and the face, and it is difficult to hold the thin film band on the face with normal spectacles. As a result, it is difficult to eliminate the gap near the back of the nose.

  In the mask described in Patent Document 2, since both side edges of the exhalation rise blocking cloth are stopped at or near the both side edges of the mask main body, the exhalation increase blocking cloth is left and right together with the mask main body when the mask is worn. Therefore, there is no play near the back of the nose and it is difficult to eliminate the gap near the back of the nose.

  In order to solve the above-mentioned problem, the applicant of the present application has proposed the utility model registration request relating to the anti-fog mask for glasses as the name of the invention submitted on the actual application 2005-005796 and August 15, 2005. Furthermore, an improvement plan is submitted to improve the adhesion.

  The present invention comprises a breathable mask body with ear hooks and a thin film piece made of a material that is thin and does not allow air to pass through, and only the upper edge of the thin film piece is formed on the inner upper edge of the mask body. A thin film in which the lower edge has a vertical width that does not completely block the nostril, and the horizontal width is the entire width of the mask or slightly shorter than that, and a plurality of cuts are made from the lower edge to the upper edge of the thin film piece. A piece is provided.

  Further, the thin film piece is folded in half in the horizontal direction from the top to the bottom in the middle, and the lower edge of the two is fixed to the inner upper part of the mask body, and the other folded part is on the face side. A thin film piece with a plurality of cuts from the lower edge of the other side of the thin film piece to the upper edge with the width of the mask being the full width of the mask or slightly shorter and the width is slightly shorter than the upper edge of the mask. It is. This thin film piece is in close contact with the face to prevent leakage to the upper part of exhaled breath and prevent inflow of pollen and dust from the outside.

  The thin film piece is folded in the horizontal direction at a substantially central portion, one side is upward and the upper edge is in the vicinity of the upper edge of the mask, the other is downward, and the lower edge is a vertical width that does not completely block the nostril. The mask is full width or slightly shortened, and the bent mountain portion is fixed to the upper part inside the mask body, and a thin film piece having a plurality of cuts from the lower edge to the upper edge of the thin film piece is provided.

  Furthermore, by providing the thin film pieces separately on the left and right sides of the mask main body longitudinal center axis on one side and the other side, the movement of the thin film pieces is increased and the face is easily adhered. As a result, it is possible to prevent the exhalation of breath near the back of the nose and prevent the inflow of pollen and dust from the outside.

  The thin film piece may be provided with a notch so that only the other side is separated left and right along the longitudinal axis of the mask body. When the mask is worn with the upper edge of the mask near the nose tip, the film piece does not hit the nostril and there is no sense of incongruity.

  When breathing while wearing the mask of the present invention, exhaled air exhaled from the mouth and nose raises the pressure of the air in the mask body, and the increased air pressure causes the other side thin film piece of the present invention to be pressed against the face. The other side thin film piece and the face are in close contact with each other so that there is no gap near the back of the nose, and as a result, exhalation does not leak from the upper part to the outside. Further, since the exhaled breath that the thin film piece softly exhales even if the mask moves slightly, the thin film piece always adheres to the face each time exhalation is exhaled. As a result, it is possible to stably prevent leakage of the exhaled air from the upper part to the outside, thereby preventing fogging of the glasses.

  Also, when the air is sucked in, the air pressure in the mask decreases and the outside air tries to flow into the mask through the gap near the back of the nose, and the one side thin film piece of the present invention is pressed against the face side by the outside air to be inflowed. The side thin film piece closes the other side thin film piece and the face to eliminate the gap near the back of the nose, thereby preventing the inflow of pollen and dust from the gap near the back of the nose. Can be increased.

  In addition, since the thin film piece has a plurality of cuts, the thin film piece becomes more flexible and can adhere more securely to the complicated shape between the nose tip, nose and cheek surface, and prevent leakage of breath. Wear a mask. When the upper edge of the mask is not selected, it works as a thin film piece near the nasal root and near the nasal apex, eliminating gaps that form near the back of the nose, preventing leakage from the upper part of the exhalation and preventing fogging of the glasses can do.

  As shown in FIGS. 1 and 2, a thin film piece 3 made of a material that does not allow air to pass through or is difficult to pass through the mask body 1 that can be ventilated and has ear hooks 2, 2 for pollen prevention, dust use, medical use, etc. Only the upper edge of the thin film piece is fixed to the inner upper edge of the mask body, the lower edge has a vertical width that does not completely block the nostril, and the horizontal width is the entire width of the mask or slightly shorter than that. A thin film piece having a plurality of cuts from the lower edge toward the upper edge is provided.

  The thin film pieces of the present invention are shown in FIGS. 3 and 4, which are folded in half in the horizontal direction from the top to the bottom, and one lower edge of the two folded is fixed to the upper part inside the mask body, and the other folded portion is On the face side, the folded fold portion folded in half is located at the upper edge of the mask body or in the vicinity of the upper edge, and the lower edge of the thin film piece 4b on the other side does not completely block the nostril. A thin film piece having a plurality of cuts from the lower edge to the upper edge of the thin film piece is provided. The thin film piece 4a on one side that is folded in the horizontal direction at the substantially central portion prevents inflow of air from the vicinity of the back of the nose, and the thin film piece 4b on the other side prevents outflow of exhalation from the vicinity of the back of the nose. is there.

  The material of the thin film piece used in the present invention may be a soft resin, such as nylon fiber, vinyl fiber, polyester fiber or the like, which is formed of a material that does not allow air to pass through or is difficult to pass through. The thin film piece for blocking exhalation is not attracted to the right and left because the side edges are not fixed, and therefore reacts well to a small exhalation flow and a small air pressure in the mask body. As a result, the thin film piece and the face can be in close contact with each other, and it is possible to prevent the exhalation of the breath near the back of the nose and the inflow of pollen and dust into the mask.

  As shown in FIGS. 5 and 6, the thin film piece is folded in the horizontal direction at a substantially central portion, with one side facing upward, the upper edge at or near the upper edge of the mask and the other facing downward, and the lower edge is the nostril. Even if the width of the mask is the entire width of the mask or slightly shortened and a plurality of cuts are made from the lower edge to the upper edge of the thin film piece, the bent mountain portion is fixed to the upper inner side of the mask body. Good. The thin film piece 5a on one side folded in half prevents inflow of air from the back of the nose, and the thin film piece 5b on the other side prevents outflow of exhalation from the back of the nose.

  Further, in the present invention, when using a mask that can be ventilated and with ear hooks 2 and 2, the gap formed in the vicinity of the back of the nose is considered to be separate on the left and right sides, and as shown in FIGS. By separately providing one on each side of the axis, the gap in the vicinity of the back of the nose is made into one thin film piece 6L, 6R on one side, which increases the degree of freedom of each, and more reliably in the vicinity of the back of the nose. It is possible to prevent exhalation leakage. In addition, notches 6cL and 6cR may be provided at the center of the thin film pieces 6L and 6R.

  The thin film pieces 7 in FIGS. 9 and 10 are also provided on the left and right sides of the mask main body longitudinal center axis separately, so that the one side thin film pieces 7aL and 7aR or the other side thin film pieces 7bL and 7bR are increased in freedom. More reliably, it is possible to prevent exhalation leakage and inflow of outside air near the back of the nose. In addition, notches 7cL and 7cR may be provided at the center of the thin film pieces 7bL and 67bR.

  The thin film piece 8 in FIGS. 11 and 12 is folded in the horizontal direction at a substantially central portion, with one side facing upward and the upper edge facing the upper edge of the mask or near the upper edge, and the other facing downward and the lower edge completely closing the nostril. The vertical width is set to the extent that there is no mask, and the horizontal width is the entire width of the mask or slightly shortened, and the bent mountain portions are fixed to the upper part inside the mask main body separately on the left and right sides of the mask main body vertical center axis. The one side thin film pieces 8aL and 8aR prevent the inflow of air from the back of the nose and the other side thin film pieces 8bL and 8bR prevent the exhalation of the exhalation from the vicinity of the back of the nose.

  Further, as shown in FIGS. 13 and 14, only the other side of the thin film piece 9 may be cut into 9cL and 9cR so as to be cut left and right along the mask body inner longitudinal center axis line to form the thin film piece 9a or the thin film pieces 9bL and 9bR. The thin film piece 9a on one side prevents inflow of air from the vicinity of the back of the nose, and the thin film pieces 9bL and 9bR on the other side prevent exhalation of breath from the vicinity of the back of the nose.

  The most important point related to the present invention is to make a plurality of cuts in each thin film piece from the lower edge to the upper edge of the thin film piece. By making this cut, the thin film piece becomes more flexible, and the thin film piece and the face can be surely adhered to each other even in a complicated shape between the nose tip, the nose and the cheek surface, and the exhalation of the breath can be prevented.

  The above-mentioned cuts may be cut in the length of about 5 to 10 mm, one in the vicinity of the left and right noses, but the width of the cut and the cut is about 3 to 10 mm, and the length of the cut is about 5 to 10 mm. preferable. The length of the cut may be the entire length of the thin film piece, and the thin film pieces 4a, 5a, 7aL, 7aR, 8aL, 8aR, and 9a that prevent the inflow of air may or may not be cut.

  A mask according to the present invention includes a breathable mask body 1, ear hook strings 2, 2 on both sides of the mask body 1, and a thin film piece provided with a plurality of cuts inside the mask body 1. The piece acts as an air valve, and when the mask is used, the gap near the back of the nose is brought into close contact with the face by the pressure and flow of outside air and exhaled air. As a result, leakage of breath from the vicinity of the back of the nose, pollen, The inflow of dust and the like can be prevented, and the original function of the mask can be enhanced.

  As for the size of the thin film piece, it is desirable that the vertical width is such that the nostril is not completely closed from the upper edge or the vicinity of the upper edge of the mask body to the vicinity of the nasal apex, and the lateral width is preferably the entire width of the mask or slightly shorter than that. The upper edge of the mask is preferably the upper part of the folded fold, but it may or may not come out. The thin film piece on one side and the other side of the folded ridge is separated from each other. The pieces may be joined to form the same shape. The size and shape of the thin film piece or the width and length of the cut may be changed depending on the shape and size of the mask and the softness of the thin film piece.
