  • Pop-open respiratory etiquette device
    Patent number: 8006694
    Abstract: A respiratory etiquette device in the form of a mask that can be held in a compacted configuration within the pocket or purse of a user. When released, the mask springs open to its erected configuration and can be quickly placed over the mouth and nose of a wearer to contain a cough or sneeze. Rapid springing open of the mask is achieved by using a plastic core having an array of external bubbles that rapidly regain their shape when the mask is released, thereby forcing the entire mask into its fully erected configuration.
