Description

The present invention relates to a sanitary mask.

Sanitary masks (hereinafter abbreviated as masks) are used to protect the nose and throat from cold and dry air, to prevent airborne particles from being taken into the body, and to protect secretions from the mouth and nose. It has the effect of preventing it from spreading. For this reason, it is important that the mask has high adhesion to the user's face.

On the other hand, masks are required to allow the user to breathe easily and to reduce discomfort such as stuffiness, and it is necessary to maintain sufficient space around the nose and mouth.

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

In a mask provided with pleats, the central portion of these pleats is pulled in the vertical direction, which is the short side direction (vertical direction), and expanded to form a dome shape or a bowl shape.

As shown in FIG. 1A, when a user A wears a mask 1 spread out into a dome shape, a space S as shown by a broken line is created around the user's nose and mouth in the wearing state.
In addition, the code|symbol 2 is an ear hook part. One end of the ear hook part 2 is fixed to the upper edge 1U side by a first fixing part 2a, and the other end is fixed to the lower edge 1D side by a second fixing part 2b.

When 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 placed on the left cheek, the right edge 1R is placed on the right cheek, and the upper edge 1U is placed below the eyes, and the lower edge 1D side is placed 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 predetermined positions, and the left edge 1L takes on a slightly curved "C" shape. . In this state, the edges 1L, 1R, 1U, and 1D of the mask 1 are in close contact with the face, and the effectiveness of the mask can be effectively obtained.

However, as shown in FIG. 2A, the user's outline is, for example, user B's outline shown by the broken line, which is narrower overall than the user A's outline shown by the solid line, or user A's outline when the width in the left and right direction is near the center. User C has a contour that is approximately the same but becomes narrower towards the chin as shown by the two-dot chain line, or user A has a contour that is overall larger than that of user A (not shown). be.

As shown in FIG. 2B, user B has a narrower overall outline than 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. , causing it to protrude from the chin.

Therefore, as shown in FIG. 2C, the user B becomes in a state where the positions of the first fixing part 2a and the second fixing part 2b are pulled toward the ear side. Then, the left edge 1L, which was previously assumed to be slightly curved in the shape of a "C" as shown by the broken line, changes to a curved shape as shown by the solid line, and with this change, the left edge A bent portion F is formed in the middle of 1L.

Then, the vicinity of the bent portion F of the mask 1 becomes lifted from the face, resulting in a decrease in adhesion. In addition, as shown in FIG. 2D, the left edge 1L side and the right edge 1R side of the mask 1 are lifted from the cheeks and chin, giving the impression that user B wearing the mask 1 has a larger appearance than the actual outline. There is a risk of giving.
In addition, when user C wears mask 1, since the width of the mask is narrow over the chin, there is a risk that the adhesion will be reduced as in the case of user B, or the appearance will give the impression that the mask is larger than the actual outline. There is a risk. Furthermore, if the user's outline is larger than the user A's outline, this can be handled by changing the mask size to a larger size.

Patent Document 1 discloses a mask that can suppress the inhalation of pollen and fine particles between the mask main body and the wearer's face. The mask main body of this mask has a lower edge shorter than an upper edge.
Therefore, when the mask is worn, the lower edge forms a shape that follows the wearer's chin. Further, it is possible to prevent a gap from forming between the welded portion provided along the lower edge of the mask body and the periphery of the wearer's chin.
