Overmolding buckles at the same time as overmolding a lens respirator
First Claim
1. A method of manufacturing a respirator mask including the following steps,providing a lens member,providing a plurality of buckle members,providing a mold member having individual mold supports to individually receive and support the lens member and to individually receive and support the buckle members at spaced positions around the lens member and to form a flange cavity around the lens member and extending to the buckle members,positioning the lens member within its individual mold support,positioning the buckle members within their individual mold supports at spaced positions around the lens member, andinjecting molding material into the flange cavity to form a flange that overmolds to the lens member while at the same time overmolds to the buckle members to form a respirator mask.

Abstract
A respirator mask and a method of making the respirator mask that includes a lens member and a plurality of buckle members spaced around the lens member. A flange member is overmolded to the lens member and to the spaced buckle members at the same time by the following method. A mold member is provided to have individual mold supports to individually receive and support the lens member and to individually receive and support the buckle members at the spaced positions around the lens member. The mold member forms a flange cavity around the lens member and extending to the buckle members. The lens member is positioned within its individual mold support and the buckle members are positioned within their individual mold supports at the spaced positions around the lens member. The molding material is then injected into the flange cavity to form a flange that overmolds to the lens member while at the same time overmolds to the buckle members to form the respirator mask.
