Abstract

La présente invention concerne un masque dans lequel les bords longitudinaux gauche et droit du masque peuvent être maintenus en contact étroit avec la peau lorsqu'il est porté. (a) Le masque (1) comprend : un corps principal de masque (2) ayant une ligne de contour formée par un bord supérieur (13) et un bord inférieur (14) qui s'étendent dans la direction gauche/droite du visage et un bord gauche (15) et un bord droit (16) qui s'étendent dans la direction verticale du visage lorsque le masque est porté sur le visage ; et une sangle (3) dont les extrémités sont fixées aux coins supérieurs gauche et droit et aux coins inférieurs gauche et droit, les bords supérieur et inférieur et les bords gauche et droit se croisant. (b) Le corps principal de masque est plié en deux le long d'une ligne centrale (31) qui se trouve entre les bords supérieur et inférieur et relie un point médian gauche (32) qui est sur le bord gauche et un point médian droit (33) qui est sur le bord droit. (c) Le corps principal de masque, plié en deux, est : soudé pour former une ligne de soudure gauche (37), le long d'une ligne diagonale gauche (36) qui relie un point (34), sur la ligne centrale, déplacé vers le point médian droit depuis le point médian gauche et un point (35) sur le bord gauche séparé par la même distance depuis le point médian gauche, vers le bord supérieur et le bord inférieur ; et soudé pour former une ligne de soudure droite (41) le long d'une ligne diagonale droite (41) qui relie un point (38), sur la ligne centrale, déplacé depuis le point médian droit vers le point médian gauche et un point (39) qui est sur le bord droit et déplacé à partir du point médian droit par la même distance, vers le bord supérieur et le bord inférieur.
