Abstract

Masque facial, comprenant un corps principal de masque facial (1). Le corps principal de masque facial (1) comprend : un bord vertical gauche (1a) et un bord vertical droit (1b); un premier pli (101), un deuxième pli (102), un troisième pli (103) et un quatrième pli (104), qui sont répartis de manière séquentielle de haut en bas lorsque le corps principal de masque facial (1) est déplié; une première section de masque (11) formée entre le premier pli (101) et le deuxième pli (102); une deuxième section de masque (12) formée entre le troisième pli (103) et le quatrième pli (104); une troisième section de masque (13) formée entre le deuxième pli (102) et le troisième pli (103); une quatrième section de masque (14) s'étendant vers le haut à partir du premier pli (101); et une cinquième section de masque (15) s'étendant vers le bas à partir du quatrième pli (104). La première section de masque (11) et la deuxième section de masque (12) sont respectivement situées sur deux côtés opposés de la troisième section de masque (13). Au niveau du bord vertical gauche (1a) et/ou du bord vertical droit (1b), une zone de séparation de déconnexion, qui s'étend en continu vers le haut à partir du premier pli (101), est formée entre la première section de masque (11) et la troisième section de masque (13). Le masque facial présente une bonne étanchéité lorsqu'il est porté, et peut améliorer l'effet de protection et réduire la possibilité d'infection.
