  By the way, in the mask which concerns on patent document 1, when the mask main body is made into the cup shape which bulged forward the center part corresponding to a person's mouth and nostril like the mask currently disclosed by patent document 2 The mask body has a front surface piece having a bulging shape portion such that a central portion corresponding to a human mouth and nostril bulges forward, and can be deformed along the bulging shape portion of the front surface piece. It is formed by the rear surface piece arranged to cover the back side of the piece. For this reason, when holding the filter sheet between the front piece and the rear piece, if the rear piece is deformed along the bulged shape portion of the front piece, the bulged shape portion of the front piece in the rear piece The wrinkles will approach the upper and lower parts of the part corresponding to. When wearing a wrinkled mask like this, the upper and lower wrinkled portions of the rear piece touch the nose and mouth, making the wearing feeling worse and giving the mouth and nose discomfort There is. Further, since the rear face piece cannot be reliably deformed along the bulging shape part of the front face piece, there is also a problem that the filter sheet cannot be reliably held by the front face piece and the rear face piece. .

  The present invention has been made in view of the above-described problems, and the configuration in which the filter sheet is held by the front surface piece and the rear surface piece is configured to cover the mouth and nose with a cup-shaped mask body. Even if it is a mask, it aims at providing the mask which can hold | maintain a filter sheet reliably with a front surface piece and a back surface piece, without giving a discomfort to a mouth and a nose at the time of mounting | wearing.

In order to achieve the above object, a mask according to the present invention comprises:
A mask body capable of covering a person's mouth and nostrils, and a pair of ear hooks connected to both sides of the mask body so as to be hung on both ears of the person. A front portion having a bulge-shaped portion such that a central portion corresponding to the mouth and nostril bulges forward, and is elastically deformable along the bulge-shaped portion so as to cover the back side of the front portion. A mask formed to hold the filter sheet for separating foreign substances in the air with the front piece and the rear piece,
The upper and lower portions of the portion corresponding to the bulging shape portion of the front surface piece in the rear surface piece are respectively cut out to form a pair of upper and lower cutout portions in the rear surface piece. (First device).

  In the present invention, it is preferable to form a pair of upper and lower notches in the filter sheet by notching the upper and lower portions of the portion corresponding to the bulging shape portion in the filter sheet (second device).

  According to the mask of the present invention, when the front surface piece and the rear surface piece hold the filter sheet, if the rear surface piece is deformed along the bulging shape portion of the front surface piece, the front surface piece in the rear surface piece. Although wrinkles tend to approach the upper and lower portions of the portion corresponding to the bulge-shaped portion of the upper and lower portions, a pair of upper and lower cutout portions are formed on the upper and lower portions, thereby preventing wrinkles from occurring on the rear surface piece. The rear surface piece can be reliably deformed along the bulging shape portion of the front surface piece. Therefore, even when the outer shape of the filter sheet is held between the front piece and the rear piece is configured to cover the mouth and nose with the cup-shaped mask body, the mouth and nose are uncomfortable when worn. The filter sheet can be securely held by the front surface piece and the rear surface piece without any problem.

  By the way, when the filter sheet held by the holding portion is deformed along the bulging shape portion of the front piece, wrinkles may be caused at the upper and lower portions of the portion corresponding to the bulging shape portion of the front piece in the filter sheet. To do. Therefore, by adopting the configuration of the second device, that is, by forming a pair of upper and lower notches by notching the upper and lower portions of the portion corresponding to the bulging shape portion of the front face piece in the filter sheet. The filter sheet can be prevented from wrinkling, and the filter sheet can be securely adhered to the front surface piece along the bulging shape portion of the front surface piece.

It is a figure which shows the mask which concerns on one Embodiment of this invention, (a) is the perspective view seen from the front, (b) is the perspective view seen from back. It is a rear view of the same mask explaining the change of the holding state of a filter sheet, (a) is a figure showing a filter sheet non-holding state, and (b) is a figure showing a filter sheet holding state.

  Next, specific embodiments of the mask according to the present invention will be described with reference to the drawings.

<Overview of mask>
A mask 1 shown in FIGS. 1A and 1B includes a mask body 2 capable of covering a person's mouth and nostril, and both ears of the person connected to both sides of the mask body 2 integrally. A pair of ear hooks 3 that can be hung on the mask body 2, and the filter sheet 4 can be attached to and detached from the mask body 2. The foreign material is captured and separated by the filter sheet 4 and used as a sanitary tool for preventing the foreign material from entering the body through the nasal cavity or the like.

<Description of the mask body>
The mask body 2 includes a front surface piece 5 on the front surface side and a rear surface piece 6 on the rear surface side, and is entirely formed in a cup shape.

  The front surface piece 5 has a bulging shape portion 5a in which a central portion corresponding to a person's mouth and nostril bulges forward. The rear surface piece 6 is arranged so as to be elastically deformable along the bulging shape portion 5 a and to cover the back side of the front surface piece 5. Both side portions of the rear surface piece 6 are joined to the front surface piece 5 by, for example, heat sealing.

  As shown in FIG. 2 (a), in the rear surface piece 6, the upper part and the lower part of the part corresponding to the bulging shape part 5 a of the front surface piece 5 are notched, respectively. A V-shaped notch 7 opened upward is formed in the upper part, while a reverse V-shaped notch 7 opened downward is formed in the lower center of the rear piece 6. Notch 8 is formed

  Further, in the rear surface piece 6, the central portion of the rear surface piece 6 is a front surface portion so that an opening 10 opened in the vertical direction is formed between the front surface piece 5 and the front surface piece 5 on the back side. A state as shown in FIG. 2 (a) separated rearward from the bulging shape portion 5a of the piece 5 (hereinafter, this state is referred to as a “filter sheet non-holding state”), and a central portion of the rear surface portion piece 6 A state as shown in FIG. 2B (hereinafter referred to as a “filter sheet holding state”) in which is closely attached to the bulging shape portion 5a of the front surface piece 5 is referred to as the “filter sheet holding state”. Can be switched by elastic deformation of the rear surface piece 6 by pushing and pulling the rear surface piece 6 against.

  Here, as a material of the front surface piece 5 and the rear surface piece 6 constituting the mask body 2, for example, a nonwoven fabric made of resin fibers such as polyester resin, polyolefin resin, nylon resin, or resin material is foamed. Examples include molded so-called foamed resins. In this embodiment, a polyurethane foam that is soft and excellent in stretchability is employed as a constituent material of the front surface piece 5 and the rear surface piece 6.

<Description of filter sheet>
As shown in FIG. 2A, in the filter sheet 4, as in the case of the rear surface piece 6, the upper portion and the lower portion of the portion corresponding to the bulging shape portion 5 a of the front surface piece 5 are notched. A V-shaped notch 11 opened upward is formed at the upper center of the filter sheet 4, while a reverse V opened downward is formed at the lower center of the filter sheet 4. A letter-shaped notch 12 is formed.

  As the filter sheet 4, for example, a natural fiber, a chemical fiber, a glass fiber, or the like is used alone or appropriately combined, and a non-woven fiber void structure in which fibers are entangled to form a sheet is suitable.

  When the mask 1 configured as described above is used, first, the rear surface piece 6 is pulled away from the front surface piece 5, and the filter sheet is not held as shown in FIG. And In this filter sheet non-holding state, the upper and lower cutout portions 11 and 12 in the filter sheet 4 and the upper and lower cutout portions 7 and 8 in the rear face piece 6 are aligned with each other through the opening portion 10. The filter sheet 4 is inserted between 5 and the rear surface piece 6, and then the filter sheet 4 is pressed against the back surface of the front surface piece 5. At this time, if the filter sheet 4 is deformed along the bulging shape portion 5a of the front surface piece 5, the wrinkles will be placed on the upper and lower portions of the portion corresponding to the bulging shape portion 5a of the front surface piece 5 in the filter sheet 4. However, since the upper and lower pair of notches 11 and 12 are formed at the upper and lower portions, the filter sheet 4 can be prevented from wrinkling, and the bulge-shaped portion 5a of the front face piece 5 can be prevented. Along with this, the filter sheet 4 can be securely adhered to the front surface piece 5.

  Next, the rear surface piece 6 is pushed toward the front surface piece 5 to obtain a filter sheet holding state as shown in FIG. At this time, when the rear surface piece 6 is deformed along the bulging shape portion 5a of the front surface piece 5, the upper surface and the lower portion of the portion corresponding to the bulging shape portion 5a of the front surface piece 5 in the rear surface piece 6 However, since a pair of upper and lower cutout portions 7 and 8 are formed in the upper and lower portions, wrinkles can be prevented from occurring in the rear surface piece 6, and the bulging shape of the front surface piece 5 can be prevented. The rear surface piece 6 can be reliably deformed along the portion 5a. Therefore, even if the mask 1 is configured such that the filter sheet 4 is held by the front face piece 5 and the rear face piece 6 so that the mouth and nose are covered with the cup-shaped mask body 2, The filter sheet 4 can be reliably held by the front face piece 5 and the rear face piece 6 without causing discomfort.

  When the used filter sheet 4 is replaced with a new filter sheet 4, first, the rear surface piece 6 in the filter sheet holding state as shown in FIG. The filter sheet is not held as shown in FIG. Next, the used filter sheet 4 is pulled out from between the front piece 5 and the rear piece 6 through the opening 10, and then the new filter sheet 4 is drawn through the opening 10 to the front piece 5 and the rear piece 6. The filter sheet 4 is held by the front surface piece 5 and the rear surface piece 6 in the same manner as described above.

  As mentioned above, although the mask of this invention was demonstrated based on one embodiment, this invention is not limited to the structure described in the said embodiment, The structure is changed suitably in the range which does not deviate from the meaning. It is something that can be done.

  Even if the mask of the present invention is a mask configured to cover the mouth and nose with a cup-shaped mask body that holds the filter sheet between the front piece and the rear piece, Since the filter sheet can be securely held between the front piece and the rear piece without causing discomfort, the filter sheet is appropriately replaced with respect to the mask body, It can be suitably used as a sanitary tool for preventing foreign matters such as dust, pollen, bacteria, and viruses floating in the body from entering the body through the nasal cavity and the like, and has great industrial applicability.
