Embodiment Construction

[0017] will now follow the attached Figures 1 to 5 A preferred embodiment of a gas filtering soft mask, indicated generally at 10, is described.

[0018] Structure and relationship of components:

[0019] according to figure 1 , the gas filtering soft mask 10 includes a soft body 12 . according to figure 2 , body 12 is formed from multiple layers of material 14 , 16 and 18 . At least one layer, typically the middle layer 16, is comprised of a gas filter material capable of selectively filtering contaminants from the air. Additionally, one of the layers may be provided with an antimicrobial agent. see you again figure 1 , the body 12 has an arcuate or raised nose engaging edge 20 which terminates at a distal end 26 along its top. see Figure 4 The nose engaging edge 20 is adapted to engage the nose 22 of the wearer 24 with its distal end 26 extending down through the cheek 40 of the wearer 24 . see Figure 5 A malleable, semi-rigid reinforcement strip 30 is secured ...

Abstract

An air filtering soft face mask has a soft body formed of multiple layers of material, including at least one layer of air filtering material capable of filtering selected contaminants from air. The body has an arcuate or peaked nose engaging edge adapted to engage a nose of a wearer and terminating in remote ends that extend downwardly. The body has a chin underlying edge adapted to underlie a chin of a wearer and terminating in remote ends that extend upwardly. The remote ends of the chin underlying edge being secured to the remote ends of the nose engaging edge to form side edges. Jaw movement tensions the body, forcing the nose engaging edge into firmer engagement with the nose of the wearer, forcing the chin underlying edge into firmer engagement with the chin of the wearer and tensioning the side edges into firmer engagement with the cheeks of the wearer.

Description

technical field [0001] The present invention relates to soft masks (as opposed to hard masks) that are constructed of filter material that can filter out contaminants and that can be used in medical and industrial applications. Background technique [0002] Air filtering masks are generally soft or hard. To be effective, they must form a gas seal so that all gas flows through the filter material as it enters and exits the mask. [0003] Soft masks made of filter material have only limited adjustment properties to different face sizes and shapes, so they cannot follow the contours of the face exactly in the same way as hard masks. And the problem is exacerbated when the wearer's jaw moves. As a result of talking or coughing, the wearer's jaw moves, causing a gap to form along the rim of the mask, which breaks the gas seal. This allows air pollutants to bypass the filter material, enter and exit the mask through gaps along the rim, thereby compromising the desired respirato...
