New description: [New technical field] This creation is about a mask that is worn to cover the mouth and nose. [Prerequisites] 4 In recent years, masks have been widely used to protect against pollen or viruses, and the like. For example, mouth. The mask disclosed in Japanese Laid-Open Patent Publication No. 1 is a mask body which is pleated in the lateral direction and has an ear-hook portion on both sides of the mask body. The mask ー described in the Japanese Patent Publication No. 1 is pleated at a constant width, and is pleated in the direction of the garden to form a plurality of creases in the lateral direction. The above: the mark is in the upper half and the lower half of the mask body, respectively, in the opposite direction: configuration. An upward finger is formed by the upper portion of the center of the mask in the longitudinal direction (center height position), and the center of the mask in the longitudinal direction (the center height position and the lower lower half form a crease to the τ. In the first section, the welding unit 13 for suppressing the expansion of the crease is also described. [Patent Document 1] Japanese Utility Model Registration No. 3117, the structure of the σ hood of the 5 brothers is used to cover The center of the longitudinal direction of the mask is mostly located in the upper half and the lower half of the wearer's σ cover when wearing, and the movable part of the face in the upper half is movable larger. The mouth of the half and the mask described in the 'Document 1' are M409853 in the longitudinal direction of the mask = above the heart, and the lower half of the upper half and below form the reverse fold = the shape of the crease Symmetrical about the upper and lower sides, the extension of the upper half of the mask, the wide discoloration and the expansion and contraction of the lower half of the σ cover are approximately the same. The retractable range of the half and the lower part of the mask is approximately the same. The range of expansion and contraction formed by creases is underutilized. Moreover, it is difficult to arrange the weeds in the lower part by the creases. It is difficult to cope with the stalks. β 助 ^ 勒勒固定: The literature 1 discloses that the fused portion 13 is affixed with a second crease: (4), but does not explain What kind of curve is used for the mask = brother (4). Although there is a thin mask on the side of the body, the extension of the body is convex, and it is a circular arc shape, an elliptical shape or a radial shape, and is a longitudinal length or a horizontal length. The research has not been carried out. [New content] There is a violent problem in the above _ questions, the purpose of this creation is to provide a kind of face: =: face action 嶋, and can be worn along the * For example, the mask of the present invention is folded in the horizontal direction to form an upwardly extending portion on the f body. The upper finger is disposed on the upper side of the central folding belt, and the downward crease is disposed on the lower side of the center folding. The vicinity of the right end of the D cover body and the left end are attached =: = the extension of the scar (four) joint, the phase = the left and right symmetry, the lateral long elliptical shape. The upper side of the central fold of the mask forms an upward crease, while in the abundance The lower side forms a downward crease. Therefore, bounded by the central folded band, Then, the crease is formed in the opposite direction to the lower side. The upward crease is a fold line that protrudes upward from the front surface of the mask = the guide 1 , and the upper end portion of the mask is pulled upward, and the upward crease is extended upward. The front view of the mask has a fold line protruding downwards, "two":: the end portion is left downwards. The downward trace is extended downwards. Therefore, the upper fold and the direction are set by the fold of the towel. The lower crease allows the central folding belt of the mask to conform to a part of the wearer's face, and the upper and lower sides can be respectively extended and contracted, and the upper and lower sides of the wearer's mouth can be opened and closed, etc., and the hood can also be expanded and contracted. At the right end of the mask body Near the left side and the left end I attach the secret part 'Transfer to suppress the upward crease and the downward crease to expand the second hunting. This can be used to maintain the mask body when the mask is worn, and maintain a smooth surface near the right end of the mask body and the left end. The surface of the refining part can be configured along the wearer's face frequency. The other aspect is placed on the inner side of the splicing portion to ensure the expansion space of the crease when the mask is worn. The welded portion is symmetrical with respect to the mask body, and is laterally long and rounded and printed. Since the shape of the lips of the general wearer is located in the left and right of the face, 2 is a horizontally long shape, and is expanded by the action of the laterally long elliptical splicing portion, and the lengthening space can conform to the shape of the edge of the wearer's lips. Therefore, it is possible to prevent the deviation of the σ cover from being swayed and comfortable when worn. Moreover, the circumference of the 'elliptical material joint portion can also be formed by the wire joint portion (the portion). By forming the surrounding joint portion, the effect of the welded portion can be exhibited, and the smooth surface can be maintained and the sense of fit can be improved. In particular, when the surrounding melting portion forms a concentric shape of the plurality of rows on the outer circumference of the flared portion, the shape of the surrounding welded portion is rounded or the ellipse lacks an elliptical arc of a knife (this is formed by the molten portion and the surrounding molten portion). The shape of the joint of the complex column ^hearted elliptical pattern can be called a multiple elliptical line.) The step of maintaining the smooth surface and improving the sense of fit. And, in the direction of the talent, it means that the folding line is folded in the horizontal direction. The position of the center of the mask body in the longitudinal direction (4) and the position of the center of the center fold (4) may be offset in the longitudinal direction. If the center position of the mask body in the longitudinal direction is offset from the center position of the central folding strip in the longitudinal direction, the wearer may be more suitable, and the mask body may be used in reverse. Corresponding to the central folding belt position on the upper side, it is felt that the comfortable soil user's belt and the towel center folding belt 4 are located on the lower side, and the comfortable wearing of the mask body can be given to the wearer by using the mask body appropriately upside down. Comfort. For example, 'by placing the central folding band above the center position of the σ cover body in the longitudinal direction', the central folding band is placed near the nose of the wearer, and the upper and lower sides of the central folding band can be respectively upward and downward. extend. The space around the nose is ensured by having the central folded band on the wearer's face that protrudes most forward to allow the wearer to breathe effortlessly. The center and the folding surface of the mask body are disposed below the position in the longitudinal direction of the mask body, so that the center folding belt can be disposed near the mouth of the wearer. Comparing the movable range of the upper and lower faces in the state of wearing the σ hood, π ""The beam 4 has a small movable range. In contrast, the lower side is the mouth and the lower head temple, and the movable range is large. 2 is the mouth and the space below, which can be used to smash the mouth of the mouth, so that the wearer can suck or talk with the mouth effortlessly. In the other side, the cover is shown on the side and the right σ g touches the mask, the mouth of the creation, the body and the ear hook, the upward crease and the downward crease of the mask. The upper finger on the u-door is placed in the horizontal direction. The upper side of the belt is placed on the upper side. The lower crease is set at the center of the center fold. The center fold is disposed in the longitudinal direction. The entire face of the mask is above the center of the nail. “ = The upper side of the center folds forms an upward crease, while the lower side of the center folds::: forms a downward crease. Therefore, with the central folded band as the boundary, the upper crease is creased in the opposite direction. The upward crease consists of a fold line protruding from the front side of the mask/A m side, which is formed by extending the upper end portion of the mask upwards upwards upwards =: by: lower: the mark is viewed from the front of the mouth, with downward The protruding weight line 'the lower end portion of the cover is pulled downward, and the downward crease is formed at the end of the downward extension. The upper fold and the downward fold are set by the central fold belt; the center fold of the cover is matched with a part of the wearer's face, and the upper [the lower side can be respectively telescopically] corresponding to the wearer's mouth. The opening and closing and the like are extended in the up and down direction, and the mask can also be stretched.
