Abstract

Ce masque respiratoire se déploie spontanément et, mis en place, il se trouve à distance de la bouche du porteur pour assurer une utilisation plus confortable. Pour obtenir ce résultat, le masque est composé d'un morceau de milieu filtrant initialement plat, plié en son milieu pour former une paroi supérieure et une paroi inférieure et présentant en supplement trois replis, dont l'un entre la paroi supérieure et la paroi inférieure et deux autres formés respectivement dans ces deux parois. Les deux parois de ce morceau de milieu filtrant plié sont réunies pour former des bords qui convergent vers l'avant. Le bord libre de la paroi supérieure comporte de préférence une bande de matière plastique armée de fil servant à conformer ce bord au contour du nez du porteur. Le masque s'accroche de préférence au porteur par des liens élastiques passant autour de ses oreilles.This breathing mask deploys spontaneously and, put on, it is away from the wearer's mouth to ensure more comfortable use. To obtain this result, the mask is composed of a piece of initially flat filtering medium, folded in the middle to form an upper wall and a lower wall and having in addition three folds, one of which between the upper wall and the wall. lower and two others formed respectively in these two walls. The two walls of this folded piece of filter media come together to form edges that converge forward. The free edge of the upper wall preferably comprises a strip of plastic material reinforced with wire serving to conform this edge to the contour of the wearer's nose. The mask is preferably attached to the wearer by elastic ties passing around his ears.
