CA 2417168

A mask that communicates a flow of breathing gas with an airway of a user is formed by a two-shot injection molding process. The mask includes a mask body and a mask seal member, at least a portion of which is molded to the mask body by a two-shot injection molding process, while the mask body is cooling and incompletely cured. The mask seal member, or a portion thereof, is molecularly bonded to the mask body as a consequence of the two-shot injection molding process.

On fabrique au moyen d'un procédé de moulage par injection en deux passes un masque communiquant un flux d'air respiratoire à une voie respiratoire de l'utilisateur. Ce masque comprend un corps et un élément d'étanchéité, dont au moins une partie est moulée contre le corps au moyen d'un procédé de moulage par injection à deux passes, pendant le refroidissement et le durcissement incomplet du corps. Cet élément d'étanchéité, ou une de ses parties, présente une adhérence moléculaire au corps résultant du procédé de moulage par injection à deux passes.
