摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional inner mask shared with a flat mask having no three-dimensionality. SOLUTION: In the three-dimensional inner mask 1 of the present invention, an upper edge horizontal chin section 10 in which a contour portion 6 abuts on a nose 71, a chin sac strip 20 in contact with a front jaw 77, and a left cheek in contact with both cheeks. It is continuously composed of a side strip 40 and a right buccal side strip 50, an upper wire portion 11 is inserted into the upper edge horizontal bag strip 10, and a lower wire portion 21 is inserted into the jaw bag strip 20. A central mountain-shaped vertical stripe 30 is formed so as to connect the intermediate position of the upper edge horizontal sac 10 and the intermediate position of the chin-sac strip 20, and the central mountain-shaped vertical stripe 30 forms a nose in front of the nose and mouth. The mouth space 70 is formed, the left side of the central mountain-shaped vertical strip 30 is sealed with the left base cloth 51, the right side of the central mountain-shaped vertical strip 30 is sealed with the right base cloth 52, and the lower wire portion 21 Can be curved in a cheek shape with respect to the anterior jaw portion 77 to erect a cheek-shaped opening 78, and the nose-mouth space 70 and the lower outside air are communicated with each other through the cheek-shaped opening 78 to facilitate breathing.
