Description

本発明は、鼻と口を覆うマスクにおいて、上部の隙間からの吐気によりメガネが曇ることを軽減させるマスクに関する。  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.

従来の一般的なマスクでは、鼻と口を覆うマスクにおいて、マスク上部と鼻と頬骨の間に形成される隙間から吐気が上昇し、吐気の水蒸気によりメガネが曇るという問題があった。  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.

このようなメガネの曇りを軽減ないし解消すべく、従来より幾つかの提案がなされている。  Several proposals have been made to reduce or eliminate such fogging of glasses.

例えば、特許文献1にあるように、マスク上部に塑性変形する樹脂や金属板をもうけ、これを鼻の形に合わせて折り曲げて前記の隙間を塞ぐように図っているものがある。  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.

また、例えば特許文献2にあるように、マスク上部に粘着性の物質を備え、鼻および頬と粘着することにより、前記隙間の密閉を図っているものがある。  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.

さらに、例えば特許文献3、4にあるように、マスク上部にスポンジ状物質を備え、前記の隙間を塞ぐように図っているものがある。  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.

さらにまた、例えば特許文献5、6にあるように、マスク上端部に薄膜状で空気を通さないか又は空気を通しにくい素材で構成された薄膜片を頬に押しつけることにより前記の隙間を塞ぐように図っているものがある  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

しかしながら、前述特許文献1に記載された塑性変形する樹脂や金属板をもうけたものでは、マスク上端部を頬に密着させることが難しく、前記の隙間を十分に塞ぐことができず、メガネの曇り止め機能は不十分である。  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.

また、前述特許文献2に記載された粘着性を付与したものでは、装着感の好みがあり、脱着回数も限定されると考えられ、必ずしも良い方法であるとはいえない。  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.

さらに、前述特許文献3、4に記載されたマスク上部にスポンジ状物質を備えたものでは、使わない時の厚み及び容積が大きく保管上で良いとはいえない。  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.

そして、前述特許文献5、6に記載された薄膜片を頬に押しつけるようにしたものでは、薄膜片が平面的であり必ずしも前記の隙間を必ずしも塞ぐとはいえず、メガネの曇り止め機能が十分とはいえない。  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.

本発明は、このような事情に鑑みてなされたもので、装着者の鼻の両側部分と頬部分およびマスク上辺で形成される隙間を塞ぎ、この隙間からの吐気によりメガネが曇ることを軽減させたマスクを提供することを目的としている。  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.

請求項1のマスクでは、鼻と口を覆うマスク本体上辺部に、通気性がマスク本体より悪く、かつ適度に柔軟性がある布状またはシート状の薄膜片を有し、薄膜片の上辺の途中を中心点にして両端部を下げることにより、薄膜片の下辺を膨らませ、鼻と頬とマスク上辺で形成される隙間を塞ぐことを特徴とする。  In the mask of claim 1, the upper side portion of the mask main body covering the nose and mouth has a cloth-like or sheet-like thin film piece which is less permeable than the mask main body and has a moderate flexibility, By lowering both ends with the middle point in the middle, the lower side of the thin film piece is expanded, and the gap formed by the nose, cheeks and the upper side of the mask is closed.

請求項2のマスクでは、薄膜片は、鼻と口を覆うマスク本体に取り付けられたもので、通気性がマスク本体より悪く、かつ適度な柔軟性を有する素材から作られ、薄膜片の上部はマスク本体の上辺部より上方に突出して延設され、使用時にマスク本体の上辺部から内側下へ逆U字形に折り曲げ、さらに折り曲げ線を中央部から端部までが一直線ではないように粘着または接合して薄膜片が膨らませ、鼻と頬とマスク上辺で形成される隙間を塞ぐことを特徴とする。  In the mask of claim 2, the thin film piece is attached to the mask body covering the nose and mouth, and is made of a material having a lower air permeability than the mask main body and having an appropriate flexibility. Extends upward from the upper side of the mask body, and in use, bends in an inverted U shape from the upper side of the mask body to the inside and down, and adheres or bonds so that the fold line is not straight from the center to the end. Then, the thin film piece swells to close a gap formed by the nose, cheeks and the upper side of the mask.

請求項3のマスクでは、鼻と口を覆うマスク本体上辺部に、通気性がマスク本体より悪く、かつ適度に柔軟性がある布状またはシート状の薄膜片を有し、薄膜片の上辺の途中を中心点にして中央部を下げることにより、薄膜片の下辺を膨らませ、鼻と頬とマスク上辺で形成される隙間を塞ぐことを特徴とする。  In the mask according to claim 3, the upper side portion of the mask main body covering the nose and the mouth has a cloth-like or sheet-like thin film piece which is less breathable than the mask main body and has a moderate flexibility, The lower part of the thin film piece is swollen by lowering the central part about the middle, and the gap formed by the nose, cheeks and the upper side of the mask is closed.

本発明では、薄膜片とマスク本体の接合部端を頂点として薄膜片の下辺が膨らみ、マスクを口鼻部に当てると膨らみは鼻と頬とマスク上辺の間に形成される隙間に集まり、隙間を減らし、メガネの曇りを軽減することができる。  In the present invention, the lower side of the thin film piece bulges with the joint end of the thin film piece and the mask body as the apex, and when the mask is applied to the mouth and nose, the bulge collects in a gap formed between the nose, cheeks and the upper side of the mask. Can reduce fogging of glasses.

本発明では、保管時のマスクの厚みはマスク本体に薄膜片の厚みが加わるだけであり、スポンジ等の弾性体を使用する方法に比べて保管の容積が少なくできる。  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.

また、薄膜片の柔軟性を適度にすることにより、薄膜片の膨らみの強度を確保して、吸気を制限する効果も期待できる。  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.
