Abstract

【課題】一般のマスクを装着した際におこる、フィルターの許容量を超えた呼気がマスク上部の鼻梁の脇から漏れることによるメガネの曇り、また、呼気に含まれる水蒸気でフィルターが目詰まりをおこし、より一層呼気が漏れやすくなることでおこるメガネの曇りを防止するマスクを提供する。
【解決手段】吸気の時だけマスクが必要と考え、呼気で開き、吸気で閉じる弁（逆止弁）を、メガネから離れたところに数箇所取り付けて、呼気は下方に排出させる。簡便性やコスト面から、マスクに穴を開け、その穴よりひとまわり大きな蓋を、開閉するように接着して弁とする例をあげる。これにより、マスク上部からの呼気の漏れによるメガネの曇り、それを助長する、水蒸気によるフィルターの目詰まりがなくなる。
【選択図】図１An object of the present invention is to wear a general mask, which causes cloudiness of glasses caused by the exhalation of air exceeding the allowable amount of the filter leaking from the side of the nasal bridge above the mask, and clogging of the filter with water vapor contained in the exhalation. The present invention provides a mask that prevents the fogging of glasses that occurs when the exhaled air is more likely to leak.
It is considered that a mask is necessary only at the time of inhalation, and several valves (check valves) that are opened by exhalation and closed by inhalation are attached at locations apart from the glasses, and exhalation is discharged downward. In terms of simplicity and cost, an example will be given in which a valve is formed by opening a hole in the mask and bonding a lid that is slightly larger than the hole to open and close. This eliminates fogging of the glasses due to the leakage of exhaled air from the upper part of the mask, and clogging of the filter by water vapor, which promotes it.

本考案はメガネが曇りにくいマスクに関する。 The present invention relates to a mask in which glasses are not easily fogged.

本考案は、一般のマスクを装着した際におこる、フィルターの許容量を超えた呼気がマスク上部の鼻梁の脇から漏れることによるメガネの曇り、また、呼気に含まれる水蒸気でフィルターが目詰まりをおこし、より一層呼気が漏れやすくなることでおこるメガネの曇りを、防止することを目的とする。 The present invention, when wearing a general mask, clouded glasses due to the exhalation that exceeded the filter's allowable amount leaking from the side of the nose bridge above the mask, and the filter was clogged with water vapor contained in the exhalation. The purpose is to prevent the fogging of the glasses that occurs when the breath becomes more likely to leak.

吸気時のみマスクが必要であると考え、呼気で開き、吸気で閉じる逆止弁を、メガネから離れたところに取り付け、呼気を下方に排出させる。簡便性やコスト面から、マスクに適当な大きさの穴を開け、その穴よりひとまわり大きな蓋を、外側に開閉するように接着して逆止弁とする例を挙げる。これによって、マスク上部からの呼気の漏れによるメガネの曇りと、メガネの曇りを助長する呼気に含まれる水蒸気によるフィルターの目詰まりを防止することができる。 Considering that a mask is necessary only during inspiration, a check valve that opens with exhalation and closes with inspiration is installed at a location away from the glasses, and exhaled air is discharged downward. In view of simplicity and cost, an example is given in which a check valve is formed by opening a hole of an appropriate size in the mask and bonding a lid that is slightly larger than the hole so as to open and close outward. Accordingly, it is possible to prevent fogging of the glasses due to leakage of exhalation from the upper part of the mask and clogging of the filter due to water vapor contained in exhalation that promotes fogging of the glasses.

Claims

Install valves (check valves) at several locations on the mask.
