Abstract
The specification sets forth a mouthpiece for use with a snorkel with or without a purge valve for use in diving. The mouthpiece is attached to a snorkel by a conduit and terminates in upper and lower lip flanges for seating within the upper and lower lips. Extending between the upper and lower lip flanges is an upper plate 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 user's upper 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 include an opening for receipt of the user's lower front teeth or 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 in a user's mouth in a facile manner without the requirement of excessive biting and eliminates prior art lugs or bits.
