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.
Claims8
A respiratory etiquette device in the form of a mask having a plastic core comprising an impervious sheet or film which is moulded in a shape for covering the mouth and nose of a wearer when the mask is in an erected configuration, the mask being crushable to a compacted configuration in which the mask can be constrained when not in use, the core having an outer surface and the sheet or film being formed to provide an array of raised areas in said outer surface for causing the mask to return to its erected configuration when unconstrained, the mask being impervious to outward expulsion of material from the mouth and/or nose of a user in sneezing or coughing, and including an opening that is closed by a filter for allowing release of excess air from a sneeze or cough.
