Gauze mask having crease structure capable of guaranteeing flat creases and three-dimensional supporting of gauze mask

Abstract

The invention discloses a gauze mask having a crease structure capable of guaranteeing flat creases and three-dimensional supporting of the gauze mask. The gauze mask is mainly subjected to the following structures: two folding parts are connected to a main sheltering sheet and a main body sheet; and the two folding parts are provided with at least three folding sheets. Therefore, under a stretched state, the various folding sheets expand and mutually brace; and through bracing force of the various folding sheets in opposite directions, a natural three-dimensional structure is formed, so that the purposes that the gauze mask has relatively good supporting force and three-dimensional sense are achieved.

Description

technical field [0001] The invention relates to a foldable mask, in particular to a mask with a crease structure which enables the mask to be folded flat and three-dimensionally supported. Background technique [0002] Generally, the existing folding mask structure only has folded creases repeatedly, and the folding methods and directions of each crease are single and parallel, without different changes. There are elastic bands for hanging ears at both ends of the body, so the following three defects are prone to occur; [0003] First, because the folding method and direction of the folds of the existing folded masks are single and parallel, the three-dimensional structure in the stretched state will be limited by the creases of each level, so that the mask can be supported when unfolded. Insufficient strength; [0004] Second, because the folding method and direction of the creases of the existing folded masks are single and parallel, when the masks are stretched, the sup...

Problems solved by technology

[0003] First, because the folding method and direction of the folds of the existing folded masks are single and parallel, the three-dimensional structure in the stretched state will be limited by the creases of each level, so that the mask can be supported when unfolded. Insufficient strength;

[0004] Second, because the folding method and direction of the creases of the existing folded masks are single and parallel, when the masks are stretched, the supporting parts protruding from each crease will be misaligned, so that the supporting force is not concentrated, and the folding There will be unevenness when folding;

[0005] Third, because the existing folding masks are all ear-hanging type, the two ends of the mask do not have a constricting structure, so when the user unfolds the mask for use, the two ends of the mask form a semi-arc shape due to the pulling of the ear-hanging elastic belt The opening of the mask greatly affects the sealing and insulation of the mask;
