This application is for an improved face mask that allows users to easily transition between a full-protection mode and a partial-protection mode. In full-protection mode, the improved face mask covers a user's mouth area and nose area. In partial-protection mode, a mask hatch removably attached to the mask frame is detached and exposes the user's face covered by the mask frame. A method of manufacturing the improved face mask is also described.

Face mask with separate inhaling and exhaling portions

A face mask with separate inhaling and exhaling portions can include an upper mask portion and a lower mask portion. A plurality of folds extend across each of the upper and lower mask portions. The lower mask portion can be larger than the upper mask portion. A lower edge of the upper mask portion can be secured to an upper edge of the lower portion. In use, the upper mask portion can cover the nose and the lower mask portion can cover the mouth. A user can inhale through the upper portion and exhale through the lower portion. In this manner, CO.sub.2 exhaled by the user will not mix with air that is inhaled.

Sanitizing face mask

A sanitizing face mask inhibits the transmission of pathogens in air respired through the nose and mouth of a wearer. The mask includes hydrophobic inner and outer layers and an intermediate layer enclosed between them. The intermediate layer is saturated with a sanitizing liquid such as an ethanol solution. Respired air encounters the sanitizing liquid as it passes through the intermediate layer, killing pathogens borne on droplets or aerosols. The sanitizing mask protects the wearer, from pathogens in the inspired air, and others, from possible pathogens in the expired air of the wearer.

A face mask that may be constructed from a series of interchangeable pieces that will form a mask that does not rest against the user's face and may allow for increased breathability and sealing.

Method and system for splicing nose wire in a facemask manufacturing process

A method and associated system are provided for splicing a reserve nose wire to a running nose wire in a facemask production line, wherein the running nose wire is supplied continuously from a supply roll. Prior to depletion of the running nose wire, the supply roll is moved from an operating location to an intermediate location that is further from the production line while continuing to supply the running nose wire from the supply roll. The supply roll is then moved from the intermediate location back towards the production line while decelerating the supply roll to a stop, thereby creating an accumulation of the running wire functionally between the supply roll and the production line. With the supply roll at a stop, the running nose wire is continuously supplied from the accumulation and a leading end of a reserve roll of nose wire is spliced to the running nose wire at a location upstream of the accumulation where the running nose wire is at a standstill. The running nose wire is then cut at a location upstream of the splice such that the reserve nose wire and reserve roll become a new running nose wire and new supply roll in the production line.

Facemask and Method of Manufacturing Same

The present disclosure is directed to a protective facemask absent of a nose wire that can be used in multiple applications, particularly in the medical field. The facemask includes a body having a top edge and a bottom edge. The top and bottom edges cooperate with each other to define a periphery that contacts a wearer's face. Further, the top edge includes a treated zone containing a surface coating. The surface coating contains a non-metal malleable material that can be manipulated so as to retain a shape that fits contours of the wearer's face.

A disposable facemask is provided having a filter body with an opening sized to cover the nose and mouth of a wearer. The filter body further includes an outer mask layer and an inner mask layer, and one or more intermediate layers disposed between the outer and inner mask layers. At least one of the intermediate layers is a nonwoven web layer including thermoplastic filaments formed from a random copolymer, or a random copolymer blended with a homopolymer.
