Breathing mouthpiece for contacting upper palate and lower jaw of user's mouth

A second stage regulator mouthpiece having a conduit connected thereto for receipt of a second stage regulator for the passage of gas through said conduit wherein the improvement comprises:

• a mouthpiece section attached to said conduit having a pair of upper and lower lip flanges wherein said lip flanges conform to the interior region between a user's lips and a user's teeth;
• said upper lip flange and said lower lip flange being at least partly joined to each other in a region intermediate between them;
• each said upper flange and said lower flange including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion;
• an upper web which conforms generally to a user's palate which extends from and is substantially coextensive with said region between said upper and lower lip flanges;
• a lower web having a pair of spaced apart tab portions which conform generally to the interior teeth and jaw regions of a user and which extend from the outer lateral region between said upper and lower lip flanges for contact with the interior lateral lower teeth of a user and spaced apart sufficiently to allow the passage of gas into a user's mouth.

The combination of a second stage regulator having a housing, valve means within said housing for conducting gas into said second stage regulator, means connected to said second stage regulator for receiving intermediate pressure, means for exhausting gas from said second stage regulator, and gas tube means extending from said second stage regulator to a mouthpiece, said mouthpiece comprising:

• conduit means for connection to the gas tube means of said second stage regulator;
• upper and lower lip flanges extending from said conduit means in a curved arcuate configuration for conformation respectively to the area between the inner surface of the lips and the outer portion of the teeth of a user;
• said upper lip flange and said lower lip flange being being at least partly joined together in a region intermediate between them;
• each said upper flange and said lower flange including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion;
• an upper interior web which conforms generally to a user's palate which extends from and is substantially coextensive with said region between said upper and lower lip flanges;
• at least a partial interior lower web extending form the region between said upper and lower lip flanges for contact with the interior lateral lower teeth of a user;
• each said upper web and said lower web including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending away from said frontal portions.

A snorkel mouthpiece comprising:

• conduit mean adapted for connection to an outlet of a snorkel so that gas being conducted by said snorkel can pass through said conduit means as well as exhaust from a user's mouth through said conduit means;
• a mouthpiece portion extending from said conduit means said mouthpiece portion having a curved upper lip flange adapted generally for conforming to the interior region of a user's mouth between the upper teeth and the user's upper lips and a curve lower lip flange adapted generally for conforming to the interior region of a user's mouth between the user's lower teeth and the inner lower lips;
• respectively;
• said upper lip flange and said lower lip flange being joined to each other in a region intermediate between them;
• each said upper flange and said lower flange including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion;
• an upper interior web joined to and extending from said region between said upper and lower lip flanges, and being anatomically shaped for contact with at least part of the inside surfaces of at least the frontal upper teeth of a user and extending at least partly in contact with a user's palate;
• and,
• a lower web joined to and extending from the region between said upper and said lower lip flanges, said lower web being anatomically shaped for contact with at least a portion of the inside surfaces of the lower teeth of a user and extending at least partly in contact with a user's interior lower jaw portion;
• and,
• each said upper web and said lower web including a frontal portion substantially coextensive with said conduit means and two opposed lateral portions extending from said frontal portion.
