Abstract

La présente invention concerne un masque ayant une fonction de contact avec le visage, une structure d'un corps de masque pouvant être directement modifiée par un porteur de telle sorte que le corps de masque ne se soulève pas du visage indépendamment de la structure ou de la taille du visage de l'utilisateur. À cet effet, le corps de masque comprend un élément de contact étroit comprenant : une première ligne de coupe qui est disposée dans la partie supérieure de son extrémité gauche et forme une première saillie de fixation selon une force externe ; une ligne de coupe pour la première saillie de fixation, qui est disposée dans la partie inférieure de son extrémité gauche et fournit un espace dans lequel la première saillie de fixation doit être ajustée de telle sorte que la partie supérieure est maintenue en contact étroit avec la partie inférieure ; une seconde ligne de coupe qui est disposée dans la partie supérieure de son extrémité droite et forme une seconde saillie de fixation en fonction de la force externe ; et une ligne de coupe pour la seconde saillie de fixation, qui est disposée dans la partie inférieure de son extrémité droite et fournit un espace dans lequel la seconde saillie de fixation doit être ajustée de sorte que la partie supérieure de l'extrémité droite soit maintenue en contact étroit avec la partie inférieure de l'extrémité droite. Selon la présente invention, même lorsque le corps de masque qui est en contact avec le contour incurvé des joues se soulève du fait de la taille ou de la courbure du visage de l'utilisateur, le corps de masque peut facilement entrer de nouveau en contact avec les joues de l'utilisateur. De plus, lorsque l'utilisateur se déplace intensément et qu'une force externe est appliquée au corps de masque, l'état de contact étroit avec les joues peut être maintenu de manière stable.
