Dans ce masque (10) jetable, le corps (20) de masque comprend des bords (20a, 20b) d'extrémité supérieure et inférieure, deux bords latéraux (20c, 20d), une partie (22) en contact avec le visage destinée à couvrir la bouche et le nez de l'utilisateur, et une partie (23) en contact avec la mâchoire faisant saillie vers le bas depuis la partie (22) en contact avec le visage de manière à présenter une forme saillante incurvée. Les deux extrémités de chacune des parties crochets (30) auriculaires sont fixées aux côtés des bords (20a, 20b) d'extrémité supérieure et inférieure, dans la partie latérale correspondante de la partie (22) en contact avec le visage, et la partie (23) en contact avec la mâchoire comprend une zone (55) à rigidité élevée qui s'étend dans le sens de la largeur (X) le long du bord (20b) d'extrémité inférieure, et présente une rigidité supérieure à celle d'autres parties.
