HORIZONTALLY FLAT-FOLDABLE MASK HAVING FIVE FACES
Document Type and Number:
WIPO Patent Application WO/2020/085779
Kind Code:
A1
Abstract:
The present invention provides a horizontally flat-foldable mask having five faces, the mask comprising a main body and harnesses supported by both side portions of the main body. When in a folded state, the main body comprises: an intermediate leaf; an upper leaf of which the upper end portion curves or slopes progressively downward from the center toward both sides; a lower leaf of which the lower end portion curves or slopes progressively upward from the center toward both sides; a first corrugated section formed extending upward from the intermediate leaf and bent horizontally from the upper leaf, and including a first intermediate bent line which curves or slopes progressively downward from the center toward both sides; and a second corrugated section formed extending downward from the intermediate leaf and bent horizontally from the lower leaf, and including a second intermediate bent line which curves or slopes progressively upward from the center toward both sides. During use, the mask of the present invention maintains a three-dimensional structure, and the intermediate leaf surrounding the mouth is parallel to the face. When stored, the mask is neatly folded without overlapping. The mask of the present invention has the advantage wherein a sealed structure can be favorably maintained by reinforcing rims of the upper leaf and the lower leaf. Also provided is a mask comprising: a grip portion that favorably maintains the edges of the mask during wear, thus allowing the mask to be handled in a sanitary manner; and a cell that improves wearing comfort.
