Abstract

La présente invention concerne un masque ayant un tampon principal vertical et son procédé de fabrication. Le masque selon un aspect de la présente invention peut comprendre : un tampon principal s'étendant dans une direction verticale ; et des sections de jupe qui sont couplées horizontalement aux côtés gauche et droit du tampon principal le long de lignes de couplage et se courbent le long des lignes de couplage par rapport au tampon principal. Le tampon principal peut comprendre : une partie de surface avant située dans une partie centrale ; une partie de support d'arc qui est située au-dessus de la partie de surface avant et plus étroite vers le haut ; et une partie de contact qui est située au-dessus de la partie de support d'arc et plus large que l'extrémité supérieure de la partie de support d'arc. Selon un mode de réalisation de la présente invention, le masque peut former un espace en forme de dôme devant le nez et la bouche d'un utilisateur et empêcher simultanément la communication involontaire d'air autour du pont du nez. Par conséquent, la zone de contact entre le masque et le nez et la bouche de l'utilisateur peut être réduite au minimum et l'air expiré contenant de l'humidité est empêché d'être évacué vers le haut, permettant ainsi à l'utilisateur d'utiliser de manière agréable le masque.
