Abstract

Procédé de fabrication de masque facial jetable. Le masque comprend un cône porteur semi-rigide sur lequel est fixé un coussin façonné selon l'invention, par moulage par injection d'une composition thermoplastique à dureté préfixée, obtenue par mélange d'un composé à mouler avec un agent de gonflement. On chauffe la composition pour la plastifier et faire libérer du gaz par l'agent de gonflement, puis on l'injecte dans un moule. On règle le degré de mise à atmosphère du moule de façon que le corps du moulage ait une structure cellulaire relativement uniforme. Le coussin résultant, très souple, est apte à épouser étroitement les traits du patient.A method of manufacturing a disposable face mask. The mask comprises a semi-rigid carrier cone on which is fixed a cushion shaped according to the invention, by injection molding of a thermoplastic composition with predetermined hardness, obtained by mixing a molding compound with a swelling agent. The composition is heated to plasticize it and release gas from the blowing agent, then it is injected into a mold. The degree of venting of the mold is adjusted so that the mold body has a relatively uniform cellular structure. The resulting cushion, very flexible, is able to closely match the features of the patient.
