  • Patent number: 6155253
    Abstract: The main purpose of the invention is to enable protective masks commonly known as "large face shield" masks to be used in a variable pressure environment, and in particular under water. The mask (1) internally comprises a pair of parallel protuberances (34) extending below the user's nose and having dimensions such as to be able to hermetically close the user's two nostrils simultaneously when applied to said nostrils by a movement from the bottom upwards. Said movement is allowed by the deformability of the gasket (4) which provides the hermetic seal between the edge (17) of the face shield (2) and the user's face.
