Abstract
Abstract The specification sets forth a mouthpiece for use with a snorkel or regulator of the type used in diving and life support systems. The mouthpiece is attached to a snorkel or regulator by a conduit and terminates in a lip flange for seating within the upper and lower lips. Extending between the lip flange is an upper palate web that conforms to the palate area of a user's mouth. Within the palate web is an opening toward the frontal area for receipt of a user's front teeth. The mouthpiece incorporates a lower web that extends along the inner jaw region overlying the inner portion of a user's lower teeth. The lower web can be split in its conformation with a gap therebetween formed by two tabs that are rounded at their ends. The entire mouthpiece conforms and holds the snorkel or regulator in a user's mouth in a facile manner without the requirement of excessive biting and eliminates prior art lugs or bits.
