An improved multi-layer face mask (10) has at least one adhesive strip applied between the inner face cover layer (36) and the intermediate filter layer (38). The adhesive strip (40) is defined so as to extend across the filter body and is bounded on each longitudinal side (42) by longitudinally extending regions (54) that are free of adhesive. The adhesive strip (40) may be disposed along a pleat (24) formed in the face mask body. For example, the adhesive strip (40) may have a width so as to extend between parallel fold lines of a pleat (24).

Cette invention concerne un masque facial multicouche amélioré comportant au moins une bande adhésive entre la couche de couverture de la face intérieure et la couche filtrante intermédiaire. La bande adhésive est définie de manière à se déployer sur l'élément de filtre et est limitée sur chacun de ses bords longitudinaux par des régions disposées longitudinalement qui sont exemptes d'adhésif. La bande adhésive peut être disposée le long d'un pli formé dans le corps du masque facial. Cette bande adhésive peut présenter une largeur correspondant à l'espace défini par les lignes parallèles d'un pli.
