Description

  The present invention relates to a three-dimensional mask formed so as to match the unevenness of the face surface.

A conventional three-dimensional mask is formed by covering a nasal cavity and mouth with a single non-woven fabric folded with a crease, and bonding a single strip-shaped synthetic resin material or wire to the upper end of the non-woven fabric. . However, the non-woven fabric also moves with the movement of the lips, and pollen and the like enter from the gaps formed on the side of the nose. In addition, since the synthetic resin material is formed so as to sandwich the nose, there is a problem that a feeling of pressure occurs.
Therefore, as disclosed in Japanese Patent Application Laid-Open No. 09-149946, a cover portion formed by laminating a low stretch nonwoven fabric covering the mouthpiece and the nasal cavity and formed in a cup shape, and continuously provided on the cover portion. There is a three-dimensional mask composed of an ear hook using a highly stretchable nonwoven fabric at both ends. With this mask, a space was provided between the nonwoven fabric and the mouthpiece, and the above-mentioned problems that caused the feeling of pressure due to movement of the nonwoven fabric or pinching of the nose were solved.
