Problems solved by technology

[0020] Such dislocation of the wearing position becomes a problem because it hinders the achievement of the purpose of the mask for the purpose of preventing exhalation leakage and outdoor air intrusion.
In addition, even in masks that are not intended to prevent exhalation leakage and outdoor air intrusion, the misalignment of the wearing position also brings discomfort to the wearer, which is also a problem.

The mask is provided with a main body part and a fixing part, wherein the main body part is used for covering the lower part, including a nose and a mouth, of a face of a wearer; the fixing part is combined with the main body part and fixes the main body part to the lower part of the face of the wearer; the main body part is provided with a main piece part, a lower strip body used for keeping the lower jaw of the wearer and / or an upper strip body used for keeping the nose of the wearer; the lower strip body is located at the lower part of the inner side of the main piece part, stretches over the left end part and the right end part of the main piece part, and is made of a strip-shaped flexible material; and the upper strip body is located at the upper part of the inner side of the main piece part, stretches over the left end part and the right end part of the main piece part, and is made of the strip-shaped flexible material.

Description

technical field [0001] The invention relates to a mask. Background technique [0002] In conventional masks, various means for closely fitting the peripheral portion of the mask to the wearer's skin have been proposed in order to prevent the leakage of exhaled air and the intrusion of outdoor air. [0003] For example, the following sanitary mask is described in Patent Document 1, which is constituted such that ear straps are installed on the left and right sides of the mask main body, and once the upper part of the mask main body is bent inwardly and downwardly, the upper part of the mask main body is bent inwardly and upwardly again. A bend is formed, and a free-bending iron wire is installed on the front end edge of the upper folded part, and the central part of the front end edge is expanded to tightly fit and support from the nose part to the cheek part. [0004] Patent Document 2 describes a mask having ear straps attached to the main body and an auxiliary sheet of br...
