Description

  The present invention relates to a sanitary mask.

  Sanitary mask (hereinafter abbreviated as “mask”) protects the nose and throat from cold and dryness, prevents airborne substances from being taken into the body, and prevents secretions from the mouth and nose. There are effects such as preventing scattering. For this reason, it is important for the mask to improve the adhesion with the user's face.

  On the other hand, the mask is required to be easy for the user to breathe and to reduce discomfort such as stuffiness, and it is necessary to maintain a sufficient space for the nose and mouth.

  At present, non-woven fabric masks are generally used, and a plurality of pleats (ridges) are provided along the long side direction (lateral direction) on the front surface of a rectangular mask body.

  In a mask provided with pleats, a central part of these pleats is pulled up and down in the short side direction (longitudinal direction) and spread to form a dome shape or bowl shape.

As shown in FIG. 1A, when the user A wears the mask 1 that is spread out in a dome shape, a space S as shown by a broken line is obtained at the user's nose and mouth in the worn state.
Reference numeral 2 denotes an ear hook. One end of the ear hook 2 is fixed to the upper edge 1U side by the first fixing part 2a, and the other end is fixed to the lower edge 1D side by the second fixing part 2b.

  When the user A wearing the mask 1 is viewed from the front, as shown in FIG. 1B, the left edge 1L of the mask 1 is arranged on the left cheek, the right edge 1R is arranged on the right cheek, and the upper edge 1U. Is arranged below the eyes, and the lower edge 1D side is arranged below the chin.

  In this wearing state, as shown in FIG. 1A, the first fixing part 2a and the second fixing part 2b are arranged at the positions assumed in advance, and the left edge part 1L has a slightly curved shape. . In this state, the edges 1L, 1R, 1U, and 1D of the mask 1 are brought into close contact with the face, so that the effect of the mask can be effectively obtained.

  However, the user's contour is, for example, as shown in FIG. 2A, the user B having a contour indicated by a broken line that is generally narrower than the contour indicated by the solid line of the user A, or the user A having a lateral width in the vicinity of the center. User C having a contour that is substantially the same but narrowing as shown by a two-dot chain line on the jaw, or a user (not shown) with a contour that is generally larger than the contour of user A, etc. is there.

  As shown in FIG. 2B, the user B has a narrower overall profile than the user A, so the left edge 1L side of the lower edge 1D and the right edge 1R side of the lower edge 1D are on the cheek. , Protruding from the jaw.

  For this reason, as shown in FIG. 2C, the user B is in a state in which the positions of the first fixing portion 2a and the second fixing portion 2b are drawn toward the ear side. Then, the left edge 1L, which has been assumed to be curved with a slight “shi” shape as shown by the broken line, changes to a curved shape as shown by the solid line, and the left edge portion is changed along with this change. A bent portion F is formed in the middle of 1L.

Then, the vicinity of the bent portion F of the mask 1 is lifted from the face, and the adhesiveness is lowered. In addition, as shown in FIG. 2D, the left edge 1L side and the right edge 1R side of the mask 1 are floated from the cheeks and chin, and the appearance of the user B wearing the mask 1 is larger than the actual contour. There is a risk of giving.
Note that even when the user C wears the mask 1, the width is narrow toward the chin, so that the adhesiveness may be reduced as in the case of the user B, or the appearance gives an impression larger than the actual contour. There is a fear. Further, when the user's contour is larger than that of the user A, it can be dealt with by changing the mask size to be larger.

Patent Document 1 discloses a mask that can suppress inhalation of pollen and fine particles between the mask main body and the wearer's face. The mask main body portion of this mask is formed such that the lower edge portion is shorter than the upper edge portion.
For this reason, at the time of mask wearing, a lower edge part forms the shape which follows a wearer's chin. Moreover, it can prevent that a clearance gap produces between the welding part provided along the lower edge part in a mask main-body part, and a wearer's jaw periphery.
