mask

The innovative mask design addresses the issue of maintaining a tight seal by folding the mask body into multiple layers, reducing tension on the nose fitter and ensuring a secure fit, thus enhancing filter efficiency and preventing glasses fogging.

AI Technical Summary

Technical Problem

Existing masks fail to maintain a tight seal between the mask body and the face, especially around the nose area, due to facial movements such as breathing and talking, which compromises the filter function and can cause glasses to fog up.

Method used

The mask design features a nose fitter positioned below the ear hook joints, allowing the mask body to fold into multiple layers. This configuration reduces the tension on the nose fitter, preventing deformation and maintaining a secure fit even during facial movements.

Benefits of technology

The design effectively minimizes gaps between the mask body and the face, ensuring optimal filter function and preventing glasses fogging, while also being comfortable and adaptable to different nose shapes.

Abstract

Prevents gaps from forming between the mask body and the face. [Solution] The mask M comprises a mask body 1, string-like ear loops 2, 2 provided at the left and right ends of the mask body 1, one or more left and right connecting parts 3 and 4 connecting the ear loops 2 and the mask body 1, and a nose fitter 5 provided to extend in the left-right direction on the mask body 1. The positions of the first left connecting part 3a and the first right connecting part 4a located at the uppermost side of the mask M are both shifted in the up-down direction from the position of the nose fitter 5, and when worn, the mask body 1 can be folded along at least one fold line F1, F2 along the left-right direction so that the nose fitter 5 does not belong to the same layer as either the first left connecting part 3a or the first right connecting part 4a, forming multiple layers.
