The pleats is configured to be folded back in the opposite direction between the upper and lower halves of the mask body, upward pleats are formed in the upper half of the center (the center height position) in the longitudinal direction of the mask, the mask downward pleats are formed in the lower half of the center of the longitudinal direction. Patent Document 1 also describes the welded portion 13 to suppress the pleats spread.

Utility Model Registration No. 3117500 discloses

Masks generally cover the muzzles is configured to be mounted so as to cover from the base of the nose to chin, center in the longitudinal direction of the mask, positioned below around and mouth of the wearer's nose often. Comparing the top and bottom halves of the mounted mask, the movable range of the face located in the upper half is relatively small, mouth and chin, etc. is disposed in the lower half, the movable range is relatively large .

However, the mask described in Patent Document 1, since the inverted pleats at half way and lower the upper half than the center in the longitudinal direction of the mask, the shape of the pleats has a vertically symmetrical, the mask the telescopic embodiment of the telescopic manner and the lower half of the upper half, becomes substantially the same manner.

Because stretchable range in and the lower half the upper half of the mask is substantially the same, may not be utilized sufficiently stretch the range formed by the pleats in the upper half, insufficient flexible range formed by pleats in the lower half There is a risk of or, there is a possibility that difficulty is arranged a mask so as to correspond to the movement of the wearer's face.

In Patent Document 1, although that the welded portion 13 constitutes a curved as a second pleat holding wires 11 and 12 are disclosed, any curve is not reached until the or thought suitable as a mask. Is described with the extending so as to project to the outside of the mask body, but either of an arcuate shape, whether it is elliptical, about what is parabolic shape, discussion of whether it is a to either Horizontal and Vertical It has not been made.

The present invention has been made in view of the above circumstances, a retractable in response to movement of the face of the wearer, to provide a mask which can be placed along the face of the wearer and exemplary problem.

In order to solve the above problems, the mask of the exemplary aspect of the present invention, and a mask body and ear portion, the mask body upward pleats and down pleats folded in the transverse direction is formed a mask, upward pleats provided above the central fold bands arranged laterally extending downward pleats are provided on the lower side of the central fold zone, the right end portion and in the vicinity of the left end of the mask body the part near has welded portion is provided to suppress the upward pleats and down the pleats spread, weld part may be formed symmetrically with respect to the mask body, and a long elliptical shape in the horizontal .

The upper side of the central fold zones of the mask is formed with an upward pleats are formed downward pleats below the central fold zone. Therefore, the central folding zone bordering open in the opposite direction on the upper side and lower side of the pleats are formed. Upward pleats has a fold which projects upwardly as viewed mask from the front, by the upper portion of the mask is pulled upward, configured so as to extend upward. On the other hand, the downward pleats has a crease projecting downward looking at the mask from the front, by the lower end portion of the mask is pulled downward, configured so as to extend downward.

By providing the upward pleats and down the pleats by a central folding zone as a boundary, and a central folding zone of the mask fitted to a portion of the face of the wearer, thereby stretching and its upper and lower, respectively it can be, it is possible to stretch the mask corresponding to the movement to expand and contract in opening and closing like a vertical direction of the wearer's mouth.

The right end near vicinity and left portions of the mask body is welded portion is provided, the welded portion is pressing the up pleats and downward pleats of the spread. In the right end portion and near the left end portion vicinity of the mask body also can maintain the smooth surface at the time of mask attachment, it can be arranged along the welded portion which is a smooth surface to the cheeks of the wearer. On the other hand, the inner part sandwiched between the welded portion, it is possible to secure the space to expand the pleats at the mask attachment.

Welded portion is a symmetrical with respect to the mask body, there is a long elliptical shape (oval shape) next. Because lip shape of the wearer is generally horizontally positioned on the left and right center of the face, a long space in the lateral widened by the action of the welding portion of the long oval shape in transverse is, to fit the shape of the wearer's lips Atari . Therefore, it is possible to improve the comfort with to prevent displacement of the mask during mounting.

Also welded portion around the welding portion of the elliptical shape (circumference welded part) may be formed. By surrounding the welded portion is formed, welded portions of the improvement of maintenance and fit of the smooth surface is effective to exert is exhibited even higher.

In particular, peripheral welded portion is formed in plural rows concentrically on the outer periphery of the welded portion of the elliptical shape, may exhibit the elliptic arc shape is an elliptical shape shape around the welded portion, or part of an ellipse deficient (such a weld portion and the welding portion shape concentric manner elliptical aspects of multiple rows formed by the peripheral welding unit, is referred to as a "multi-oval line shape".) the improvement of maintenance and fit of the smooth surface effects etc. are exhibited even more improved. Here, "folded in the transverse direction", polygonal line says that the folded state so that the transverse direction.

And the center position in the longitudinal direction of the mask body, and the center position in the longitudinal direction of the center fold zone may be offset in the longitudinal direction.

If shift and the center position in the longitudinal direction of the central position and the central folding zone in the longitudinal direction of the mask body can be fit to the fit of the wearer, for use upside down the mask body. Wearer and the better the central folding zone is located at the top slightly feel comfortable, slightly depending on the wearer is better positioned below feel comfortable, by using in the appropriate upside down the mask body, more often It contributes to the comfort of the wearer.
