Dual chambered protective mask and frame insert for forming the same

A frame insert for transforming a single-chambered mask into a protective dual-chambered mask, comprising:

• a support member integrally formed having a first edge, a second edge and a curved strut connected together along the periphery of said support member, and a panel section disposed therebetween, the first edge and the second edge converging forwardly about the panel section at a vertex at the front of support member and the curved strut extending transversely between separate ends of the first edge and second edge to provide an arcuate base opening opposite to the vertex, the first edge and the second edge further formed having an interstitial space along their respective lengths to fasten the support member to the single-chambered mask in an engaged mask assembly, whereby the support member in the engaged mask assembly substantially divides the single chamber of the mask into an isolated two-chamber mask for healthier breathing and also eliminates leakage gaps between the mask and the frame insert.

• a support member integrally formed having a first edge, a second edge, an intermediate edge connected between the first and second edges, a curved strut connected along the periphery of said support member, and a panel section disposed therebetween, the intermediate edge being disposed forwardly on the support member and the curved strut extending transversely between separate ends of the first edge and second edge to provide an arcuate base opening opposite to the intermediate edge, all of said edges being further formed having an interstitial space along their respective lengths to fasten the support member to the single-chambered mask in an engaged mask assembly, whereby the support member in the engaged mask assembly substantially divides the single chamber of the mask into an isolated two-chamber mask for healthier breathing and also eliminates leakage gaps between the mask and the frame insert.

A mask assembly comprising:

• a mask body having an outer surface and an inner surface covering at least the nose and mouth, a pair of ear loops disposed on the mask body;
• and
• a frame insert configured to act as a separation means which is substantially dividing said inner surface into a nose portion and a mouth portion, thereby, forming a nose chamber and a mouth chamber with separate airflows, the frame insert includes a curved strut and a periphery part which is separated from the mouth and nose by an appropriate distance and the mask is covered on the outside.
