摘要

Disclosed are a personalized dust mask and a method for manufacturing a personalized dust mask. The disclosed personalized dust mask is manufactured by injection molding a thermoplastic resin made of PMMA (Poly Methyl Methancrylate), is made in a dome shape to cover the entire face including eyes, nose, and mouth, and has a ring-shaped fitting groove so that the packing member is fitted. a mask body formed on the inner edge; and a packing member having a fitting protrusion coupled to the fitting groove formed on the inner surface of the mask body to improve sealing properties between the mask body and the face in close contact with the face surface, wherein the packing member is coupled to the mask body In this state, the mask body is softened by heating it to the glass transition temperature, and then the softened edge of the mask body is pressed against the face so that the edge of the mask body is deformed to correspond to the curved line of the user's face. By molding, the packing member is configured to have a shape corresponding to the curved line of the user's face, so that adhesion with the face is improved.
