The size is preferred. Moreover, in order to improve air permeability, it is preferable to use a polyurethane cell film removed.

<About filters>
The filter 3 will be described with further reference to FIGS.

  The filter 3 does not have a pair of ear hooks, is formed in a three-dimensional shape with a central portion protruding forward along the three-dimensional shape of the mask main body 2, and is disposed along the inner surface of the mask main body 2. The outer shape of the filter 3 is formed smaller than the outer shape of the mask body 2. As shown in FIG. 3, the filter 3 includes an upper region 3 </ b> A that is located above and is continuous in the left-right direction, a lower right region 3 </ b> B that is located on the lower right side of the upper region 3 </ b> A, and a lower left that is located on the lower left side of the upper region 3 </ b> A. And a region 3C.

  As shown in FIG. 5, the filter 3 is formed from a sheet 40 having a substantially rectangular shape when viewed from the front. The sheet 40 is provided with a cut portion 41 (a portion indicated by hatching) that is cut from below to above at a central position in the left-right direction. The cut portion 41 is cut out and the end portion 3b of the lower right region 3B and the end portion 3c of the lower left region 3C facing the lower right region 3B are bonded and fixed, thereby forming the bonded portion 30 (FIG. 3). The Furthermore, in order to make the filter 3 conform to the shape of the jaw, a pair of corner portions 42 (portions indicated by hatching) where the left and right side sides 401 and the lower side 402 of the sheet 40 intersect are cut out. .

  The bonded portion 30 only needs to be bonded to the end portion 3b of the lower right region 3B and the end portion 3c of the lower left region 3C. For example, the bonded portion 30 may be bonded by sewing, fusing, welding, or the like. The adhesion part 30 of this Embodiment is formed by heat sealing | fusion. With such a configuration, the mask body 2 has the adhesive portion 20 protruding forward in a curved shape between the upper and lower sides when in use, and when not in use, the mask body 2 is folded in two with the adhesive portion 20 as a boundary as shown in FIG. Is possible.

  The filter 3 has a plurality of stacked sheets. The filter 3 of the present embodiment has a two-layer structure, for example. The two peripheral laminated sheets are joined at their outer peripheral edges by, for example, thermocompression bonding. The filter 3 is made of, for example, a thermoplastic nonwoven fabric. The mask main body 2 of the present embodiment uses a nonwoven fabric formed of polytetrafluoroethylene (hereinafter referred to as PTFE).

  As shown in FIG. 3, the filter 3 has a long core member 32 that deforms along the shape of the user's nose. When used, the core member 32 is in close contact with the face crossing the nose along the concavo-convex shape of the nose, and plays a role of retaining the portions corresponding to both side surfaces of the nose. The core material 32 extends along the upper side of the filter 3. Specifically, the core member 32 is provided in the upper region 3A and extends in the left-right direction. The core material 32 is, for example, a metal or a resin that is flexible and flexible and has shape retention.

  The core member 32 is stored in a storage portion 34 that extends along the upper side of the filter 3. Here, the storage part 34 is formed by bonding predetermined regions of a plurality of sheets in the thickness direction to form a bag. Specifically, the storage portion 34 is a portion surrounded by a bag shape by a heat welding portion 33 provided at an interval in the upper region 3A. Since the storage portion 34 is provided in the upper region 3 </ b> A, which is a region continuous in the left-right direction, the storage portion 34 is continuous in the left-right direction.

  The storage portion 34 is formed to be slightly larger than the size of the core member 32. Thereby, it is easy to store the core material 32, and the core material 32 can be prevented from moving inside the storage portion 34. Furthermore, since it is only necessary to cut and bond the sheet having a rectangular shape in front view, the filter 3 can be easily manufactured. Furthermore, since the core member 32 is disposed in the upper region 3A continuous in the left-right direction, the core member 32 can be easily attached.

<How to wear the sanitary mask>
With reference to FIGS. 6 and 7, a method of wearing the sanitary mask 1 will be described.

  First, as shown in FIG. 7, the mask body 2 folded in half is opened, the filter 3 folded in half is opened, and the filter 3 is arranged along the inner surface of the mask body 2.

Next, with the filter 3 placed on the mask body 2, the ear hooks 23 and 24 are attached to the user's ears, and the sanitary mask 1 is attached to the face as shown in FIG. The core member 32 of the filter 3 is pressed from above the mask main body 2 and deformed along the three-dimensional shape of the user's nose to fit the nose.

  Thereby, since the core material 32 fits with a user's nose, even if it does not connect the mask main body 2 and the filter 3 directly, there is no possibility that the filter 3 may move on the inner surface of the mask main body 2 in use. Furthermore, by placing the filter 3 made of PTFE on the mask body 2 made of polyurethane, a frictional resistance is generated between the filter 3 and the mask body 2. Even if it is vertical, the filter 3 is unlikely to fall from the mask body 2. Furthermore, the filter 3 is not easily displaced after being mounted.

  Further, since the mask body 2 and the filter 3 are not connected to each other, when the filter 3 becomes dirty, it is possible to easily replace only the filter 3. A so-called disposable filter that can be repeatedly used after being washed and employed as the mask 3 may be employed. Thereby, the sanitary mask 1 can always be kept clean while using the mask body 2 repeatedly.

  As a sales form, the mask body 2 and the filter 3 may be overlapped and sold as the sanitary mask 1, or only the filter 3 may be sold as a sanitary mask filter alone.

  In the present embodiment, the mask body 2 and the filter 3 are not connected, but this is not restrictive. For example, the filter 3 may be detachably bonded to the mask body 2.

  Further, in the present embodiment, the core member 32 is stored in the storage portion 34. However, the core material 32 may be directly bonded to the surface of the filter 31 without providing the storage portion 34. Moreover, the formation method of the accommodating part 34 is not limited to thermocompression bonding, For example, you may form by sewing.

  Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same range as the present invention or within an equivalent range.
