Title
(EN) Respirator mask and method of manufacturing a mask
Abstract
(EN) A respirator mask 10 comprising a chassis, seal, formed filter sheet comprising multiple sheets, elastic headbands 25 and clasps 28. The chassis provides a substantially circular framework 22 with a pair of ribs 26 that may be in an X shape. The filter is attached to the exterior of the chassis and supported by the ribs to form a dome- or cup-shaped pocket. The seal is attached to the framework to provide a face seal such that the cup portion can provide an air pocket. Two clasps 27 may be arranged on either side of the framework aligned at approximately 40° to each other. The headband may be adjusted by a hinge mechanism. A method of making a cup-shaped filter for a mask comprising placing multiple filter sheets into a cavity cast with a crease forming plunger frame and applying a cup-shaped plunger to provide an evenly creased filter sheet.
