ある。(Embodiment) FIG. 1 is a front view of an embodiment of a simple mask according to the present invention,
2 is a bottom view of FIG. 1, and FIG. 3 is III- in FIG.
It is a sectional view taken along the line III. In the figure, 1 is a bowl-shaped mask body. The bowl-shaped mask body (1) is usually made of a hard synthetic resin molded body, but any material may be used as long as it is rigid enough not to deform when the mask is used. Inside the bowl-shaped mask body (1), the bowl-shaped mask body (1)
A molded filter material (2) molded into substantially the same shape as the above is disposed with a gap between the filter material and the bowl-shaped mask body. The molded filter material (2) is fixed to the bowl-shaped mask body by any means, for example, by adhesion, welding, sewing, or the like, at the entire circumference or a part of the portion abutting on the peripheral portion (3) of the bowl-shaped mask body. ing. A large number of elongated ventilation holes (4) are provided in the lower half of the bowl-shaped mask body, and projections or ridges (5) are provided on the inner surface of the bowl-shaped mask body to prevent adhesion of molding filtration. This protrusion or ridge may be omitted in some cases.
In the figure, reference numeral 6 is a mounting string attached to the bowl-shaped mask body.

気孔（14）を設けた構成にある。FIG. 4 is a front view of a second embodiment of the simple mask according to the present invention. This embodiment differs from the embodiment shown in FIGS. 1-3 in that instead of providing a large number of vent holes (4) in the lower half of the bowl-shaped mask body (1), one large passage is formed in the center thereof. The structure is provided with pores (14).

けでもよい。Since it has the above-mentioned configuration, when using it, the intake air passes through the ventilation hole (4) and the interval (7), and then the sheet-like filtration material (2).
Passes through and is purified and enters the mask. Exhaled air flows in the opposite direction and is released outside the mask. In the above-mentioned embodiment, the molded filter material is fixed to the peripheral portion of the bowl-shaped mask body with an adhesive or the like, but this may be simply contacted.

にしかも安価に製造できる。(Effect of the Invention) According to the present invention, the mask body is integrally molded into a desired shape structure with a synthetic resin material or the like, and the molded filter material formed into the required shape is simply fitted inside the mask body. Since the mask is completed with, the mask can be manufactured very easily and at low cost.
本考案のマスクにおいては、成形ろ過材（２）の全周縁
部が椀形マスク本体（１）の周縁部により顔面に押圧さ

面を吸気のろ過に利用でき、したがって、比較的に吸気
抵抗が低く、しかも比較的に長期にわたり、良好なろ過
能を有するマスクを得ることができる。In the mask of the present invention, since the molded filter medium is always arranged inside the bowl-shaped mask body at a position where a required distance is provided between the inner face and the inner face of the bowl-shaped mask body, almost all of the molded filter medium is constantly sucked. It is possible to obtain a mask which can be used for filtration and therefore has a relatively low inspiratory resistance and has a good filtering ability for a relatively long period of time.
特に、第２実施例のマスクの場合には、マスク装着時
に、その通気孔を密着性試験用治具や手などで閉じるこ
とにより、顔面密着性を試験することができる。In particular, in the case of the mask of the second embodiment, the face adhesion can be tested by closing the ventilation hole with a jig for adhesion test or a hand when the mask is attached.
