Title:
MASK WITH COMPREHENSIVELY ENHANCED CLOSE FIT
Document Type and Number:
WIPO Patent Application WO/2024/060051
Kind Code:
A1
Abstract:
A mask with a comprehensively enhanced close fit. The mask comprises a face mask body (1), wherein an upper sealing edge (2) or/and a lower sealing edge (3) of the face mask body (1) is/are folded towards an inner side of the mask body (1); two sides of the upper sealing edge (2) or/and the lower sealing edge (3) are connected to the face mask body (1); folds which make the longitudinal width of the mask adjustable when the mask is unfolded are arranged on the face mask body (1); two sides of the folds are fixedly connected to left and right sides of the mask body (1); a contraction gap (6) is provided between the folds; and a scissors-type staggered superimposition is formed at two sides between adjacent edges of the folds by means of the contraction gap (6) when the mask is unfolded. A scissors-type staggered superimposition can be formed between side edges of two adjacent folds of the mask, such that the side edges of the mask can naturally form curves, and the side edges of the mask are prevented from turning inside out and arching up; moreover, when the upper sealing edge (2) or the lower sealing edge (3) is unfolded, the upper sealing edge and the lower sealing edge (3) naturally generate a pulling force under which the upper sealing edge and the lower sealing edge converge inwards, such that the close fit is enhanced, and thus protection can be comprehensively strengthened; in addition, the mask can better adapt to faces of different sizes; and ear straps (7) can be in large-area contact with the base of ears, such that the mask is more comfortable to wear.
