Abstract

PROBLEM TO BE SOLVED: To reduce fogging of spectacles by reducing a gap formed between a mask upper part, the nose, and the cheekbone and reducing leakage of respiration from the gap in a mask for covering the nose and the mouth.SOLUTION: A thin film piece 30 having appropriate flexibility is provided at an inside upper side part of a mask body 10, and a lower-side intermediate part of the thin film piece is expanded to reduce a gap formed between a mask upper part, the nose, and the cheekbone. Expansion methods include the methods of: drawing the lower part of the thin film piece from the left/right; and attaching a plastically-deforming material to the thin film piece lower part and using the deformation of the material. One or both of them are used for the expansion method.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a mask covering a nose and a mouth, which reduces a gap in the upper part, reduces leakage of breathing, and reduces fogging of glasses due to breathing.

  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 disclosed in Patent Documents 5 and 6, for example, only the upper edge of a thin film piece made of a material that does not allow air to pass through or is difficult to pass air is fixed to the upper end of the mask, There are some that try to close the gap by pressing the thin film piece against the cheek using the air pressure of

  None

  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 is pressed against the cheek using the air pressure in the mask by the exhalation described in Patent Documents 5 and 6, the thin film piece moves by respiration, and the thin film piece does not necessarily block the gap. However, it cannot be said that the anti-fogging function of the glasses is sufficient.

  The present invention has been made in view of such circumstances, and reduces gaps formed on both sides of the wearer's nose, cheeks, and the upper side of the mask, reduces breathing leakage from the gaps, and the glasses become cloudy. The object is to provide a mask that reduces this.

  In the mask according to claim 1, the upper side of the mask body covering the nose and mouth has a cloth-like or sheet-like thin film piece that is less breathable than the mask main body and has moderate flexibility, and the upper side of the thin film piece. The lower part of the thin film piece is swollen by lowering the center part and the end part from the middle of the point, and the gap formed by the nose, cheeks and the upper part of the mask is reduced.

  In the mask according to claim 2, the upper side of the mask body covering the nose and the mouth is made of plastic, aluminum, or the like on the lower side of a cloth-like or sheet-like thin film piece which is less permeable than the mask body and has a moderate flexibility. By attaching a plastically deformable material and folding the thin film piece into a nose shape, the thin film piece bulges that reduce gaps formed by the nose, cheeks, and the upper side of the mask are stably held.

  According to a third aspect of the present invention, a thin film piece is provided on the inner upper side of the mask body covering the nose and mouth, and a part of the thin film piece is moved to inflate the lower side to reduce a gap formed by the nose, cheek and upper side of the mask. The mask is characterized in that the position of movement according to the degree of swelling is easily understood by marking the position of the movement of the thin film piece, and the reproducibility is improved.

  In the present invention, when the mask is used, the lower side of the thin film piece is inflated, so that when the mask is applied to the mouth and nose, the expansion reduces the gap of respiratory leakage formed between the nose, cheeks and the upper side of the mask, and Cloudiness can be reduced.

  In addition, when moving a part of the thin film piece to adjust the size of the bottom of the thin film piece to match the shape of the face of the person wearing the mask, the thin film piece is inflated by marking the position of the movement. It will be a measure of size and reproducibility can be expected.

  Since the plastically deformable material attached to the lower side of the thin film piece in the present invention is not subjected to the tension from the ear strap, the thin film piece can be stably bulged and the leakage of the breath can be kept small.

  In the present invention, since the thin film piece and the side surface of the nose are in contact with each other at the lower part of the thin film surface, interference between the nose pad of the glasses and the mask can be reduced as compared with a method using an elastic body such as a sponge on the upper side of the mask.

  The mask of the present invention has a three-dimensional shape when used, but is planar when stored, and the volume of storage can be reduced compared to a method using an elastic body such as a sponge.

It is a back view at the time of using a film piece inflated with a mask same as the above It is the figure which looked at the same mask from the top. It is a pleated type mask which shows embodiment of Claim 2, and is a back view of a mask which lowers both ends of a thin film piece, and makes a lower side approach and swells It is a back view at the time of using a film piece inflated with a mask same as the above It is a pleated mask which shows embodiment of Claim 2, and is a back view before inflating using the elastic thin film piece. It is an example of the mark attached to the mask of Claim 3. It is a three-dimensional mask which shows embodiment of Claim 2, and is a back view of the mask which lowers the both ends of a thin film piece, and swells it by bringing a lower side near. It is a back view at the time of using a film piece inflated with a mask same as the above It is a three-dimensional mask which shows embodiment of Claim 2, and is a back view before inflating using the elastic thin film piece. It is a three-dimensional type mask which shows embodiment of Claim 2, and is a back view before the mask which folds and uses a thin film piece is expanded.

  The mask body and the thin film piece are bonded or adhered on the upper side of the mask body. However, it is better to bond or place an adhesive near the lower side of the thin film piece to prevent the mask body and the thin film piece from shifting and to ensure stable bulging. .

  The thin film piece or the mask main body may be attached to the adhesive portion.

  When a plastic material is attached to the lower side of the thin film piece to expand the lower side of the thin film piece, the upper side of the thin film piece may be joined to the mask body using a stretchable material.

  The mark may be a scale or a shape.
