PROBLEM TO BE SOLVED: To provide a snoring prevention mask which is easy to wear, has comfortable wearing feeling, and is capable of preventing opening of the mouth by holding the lower lip securely while sleeping. SOLUTION: The mask 1 has a two-ply bag shape covering both the upper and the lower lips. A rubber band 3 extending from both the upper corners is put on the head, and a string 4 passed through the lower side of the mask 1 is pulled to hold the chin and is bound behind the neck. The upper rear surface of the mask 1 having a two-ply bag shape is cut in U shape to form a single layer section, and the lower lip is held by the two-ply section. The mask 1 is made of a thin cotton cloth. COPYRIGHT: (C)2006,JPO&NCIPI
