FIG. 10 is a front view for explaining the action of the mask according to the present embodiment. FIG. 10 is a side cross-sectional view showing the positional relationship between the shape-retaining member and the face when the mask is attached to the face.

  As shown in FIG. 1 to FIG. 4, this dustproof mask has a mask body 1 that is sized to cover the lower surface of the nose 81, mouth 82, and jaw 83 when worn on the face, and the entire mask body 1. A stretchable face cloth 2 that extends inwardly from the peripheral edge and has an opening 2a at a position corresponding to the nose 81 and the mouth 82 when the mask body 1 is attached to the face, and the mask body It is comprised from the lace 3 for attaching 1 to an outer surface.

  A portion of the mask body 1 corresponding to the nasal bridge 81a (the central upper part in the left-right direction) has a concave nose pad portion having a depth such that the mask body 1 is spaced from the nasal bridge 81a when the mask body 1 is mounted on the face. 1a is provided, and left and right side portions of the mask body 1 are provided with cheek contact portions 1b that come into contact with the cheek 84 when worn on the face, and portions corresponding to the jaws 83 of the mask body 1 (left-right direction) A chin contact portion 1c that can cover the lower surface of the jaw 83 when it is attached to the face and that is not partly or entirely abutted or touched on the lower surface of the jaw 83 is provided at the lower center of the chin.

  And the mask main body 1 is comprised so that it may deform | transform in the up-down direction, when the right and left side part bends following the motion of the face.

  In this case, the mask body 1 is formed of a flexible sheet-like member 10 on the outer surface side and a material having an appropriate elasticity that is disposed on the inner surface side of the sheet-like member 10 and maintains the shape of the mask body 1. It comprises a shape member 20. The sheet-like member 10 is composed of, for example, a non-woven fabric, a woven fabric, or a single-layered or laminated body of a knitted fabric, or a stuffing in a bag formed of an outer layer and an inner layer of a non-woven fabric. Yes. For example, polyethylene, polyvinyl chloride, polypropylene, rubber, or the like can be used for the shape retaining member 20, and any material having appropriate elasticity may be used.

  As shown in FIGS. 5 to 9, the shape-retaining member 20 formed of a material having moderate elasticity has a three-dimensional shape along the entire outer peripheral edge of the mask body 1 and not along the undulation of the face. The annular portion 21 is formed, and a crosspiece 22 stretched in a net shape that is curved by joining the end portion to the annular portion 21. The crosspiece 22 is composed of several vertical crosspieces 22a arranged at intervals and several horizontal crosspieces 22b provided so as to intersect therewith.

  A nose pad portion 21a formed in a concave shape with a depth so as to be spaced from the nose bridge 81a when the mask body 1 is mounted on the face is provided at the center upper portion in the left-right direction of the annular portion 21. The cheek abutment portion 21b is provided on the left and right sides of the annular portion 21 so as to bite into the cheek 84 when the mask body 1 is mounted on the face. There is provided a chin rest portion 21c that can cover the lower surface of the jaw 83 when the is attached to the face, and that a part or all of the lower surface of the jaw 83 abuts or does not abut.

Thus, since it is configured with the crosspiece 22 stretched in the shape of a curved net, when the shape retaining member 20 is deformed, it can be deformed while keeping the circumferential length of the annular portion 21 constant. Accordingly, when the left and right cheek support portions 21b bend in the left and right direction following the movement of the face, the nose contact portion 21a and the chin contact portion 21c at the center portion in the left and right direction can be displaced in the vertical direction accordingly. it can. Therefore, following the movement of the face accompanying the movement of the mouth, the mask main body 1 can be easily deformed while maintaining adhesion, and the mask main body 1 can be made difficult to shift upward or downward. .

  Further, the mask of the present embodiment has the chin rest portion 1c in which the mask body 1 can cover the lower surface of the jaw 83 and part or all of the lower surface of the jaw 83 does not contact or contact, so It is possible to prevent the mask body 1 from being dragged up by the movement. In addition, since the face cloth is in close contact with the face so as to compensate for the gap formed between the chin rest portion 1c and the jaw 83, it is possible to prevent the mask body 1 from sliding down while maintaining the adhesion.

  Further, since the nose pad portion 1a of the mask body 1 does not directly touch the nasal bridge 81a, the nasal bridge 81a does not hurt even when worn for a long time. In addition, since the nose pad portion 1a does not hit the nose bridge 81a, which is a hard part of the face, it can be dragged by the movement of the mouth and no extra gap can be formed between the face and the mask body 1 can be raised. Can be prevented. Further, since the face cloth 2 is in close contact with the face so as to compensate for the gap formed between the nose pad portion 1a and the nose bridge 81a, it is possible to exhibit good wearability while maintaining close contact. The face cloth 2 may be a non-breathable material such as urethane or silicone, for example, a single layer body made of a non-breathable material, or a laminate including at least one layer made of a non-breathable material. But you can.

  Further, the cheek portion 1b is provided on the left and right side portions of the mask body 1, and the cheek portion 1b hits the cheek 84 which is not a hard part of the face, so that it feels pain while maintaining the adhesion. It is possible to keep good fit.
