Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 9.

FIG. 1 is a view from the inside of a state in which the inner sheet A according to the embodiment of the present invention is adhered to the mask B. FIG. 2 is a view in which the inner sheet A is adhered to the inner sheet B and attached to the face. FIG. 3 is a side view of the inner sheet A. FIG. 4 is a view of the upper curved portion 11 as viewed from the rear. FIG. 5 is a view of the upper curved portion 11 as viewed from the front. FIG. 6 is a diagram showing a sheet-shaped blank B1 before bending the upper curved portion 11. FIG. 7 is a diagram showing a sheet-shaped blank B2 before bending the lower curved portion 12. FIG. 8 is a contact view of the nose and the main body A when the inner sheet A is worn on the face, as viewed from above. FIG. 9 is a view of the inner sheet A viewed from below.

As shown in FIG. 1, the inner sheet A is a sheet attached to the inside of the mask B in order to maintain the space of the mask B. The inner sheet A is attached (joined) to the inner surface of the mask B by using a joining means (for example, double-sided tape or the like). The inner sheet A has a sheet-shaped upper curved portion 11 that is convexly curved toward the front, a sheet-shaped lower curved portion 12 that is convexly curved toward the front, and an upper end portion of a central portion in the left-right direction of the upper curved portion 11. The nose pad portion 13 is provided in the above and projects rearward from the central portion in the left-right direction of the upper curved portion 11.

The upper curved portion 11 includes a frame-shaped frame F1 for partitioning a plurality of windows 16 and a mesh-like sheet S1 attached to the rear surface of the frame F1 and covering the frame F1 and all the windows 16.
The upper curved portion 11 is formed by attaching a mesh-like sheet S1 to the rear surface of the sheet-shaped blank B1 and bending it around an axis extending in a predetermined direction in which the upper side is tilted backward with respect to the vertical direction. There is. The upper curved portion 11 is a curved body having a radius of 58 to 78 mm, preferably a radius of 63 to 73 mm in a normal size mask B. The smaller size mask B is a curved body having a radius of 21 to 41 mm, preferably 26 to 36 mm.

The lower curved portion 12 includes a frame-shaped frame F2 for partitioning the plurality of windows 17, and a mesh-like sheet S2 attached to the rear surface of the frame F2 and covering the frame F2 and all the windows 17.
The lower curved portion 12 is formed by attaching a mesh-like sheet S2 to the rear surface of the sheet-shaped blank B2 and bending it around an axis extending in a predetermined direction in which the lower side is tilted backward with respect to the vertical direction. There is. The lower curved portion 12 is a curved body having a radius of 72 to 92 mm, preferably a radius of 77 to 87 mm in a normal size mask B. The small size mask B is a curved body having a radius of 81 to 101 mm, preferably a radius of 86 to 96 mm.

Both ends of the upper curved portion 11 and the lower curved portion 12 are connected to each other in the left-right direction. A total of two protrusions P, which project downward, are formed at the lower ends of both ends of the upper curved portion 11 in the left-right direction. A total of two notches N are formed at the lower ends of both ends of the lower curved portion 12 in the left-right direction. By inserting the protrusion P into the corresponding notch N, the joint between the upper curved portion 11 and the lower curved portion 12 is achieved. The nose pad portion 13 and the frames F1 and F2 are formed by bending and cutting out the sheet-shaped blanks B1 and B2.

The nose pad portion 13 is a member having an inverted trapezoidal shape when viewed from the front, which is formed by denting the central portion of the upper portion of the upper curved portion 11 rearward. Specifically, the nose pad portion 13 pushes and bends the central portion of the upper curved portion 11 backward so that even if the mask B is worn for a long time, a gap is surely created in front of the nostrils and the mouth, and the mask. Prevents B from sticking and enables the user to breathe and talk easily. The nose pad 13 is a curved body having a radius of 49 to 69 mm, preferably a radius of 54 to 64 mm in a normal size mask B. The smaller size mask B is a curved body having a radius of 19 to 39 mm, preferably a radius of 24 to 34 mm.

As shown in FIG. 1, since the mesh-like sheets S1 and S2 are provided on the entire inner surface of the inner sheet body A that keeps the space inside the mask B, the inner sheet body A is attached with good contact with the face. Reduce the feeling.

As shown in FIG. 2, since the nose pad 13 of the inner sheet body A hits between the back of the nose and the tip of the nose, an appropriate gap is formed in front of the nostrils and the mouth, and the mask B itself is difficult to move up and down and is light. Since it does not interfere with nasal breathing, the user can easily breathe and talk.

Since the upper curved portion 11, the lower curved portion 12, and the nose pad portion 13 have a certain degree of elasticity and strong rigidity, it is easy to cut and fold the nose pad portion 13, but even those having no elasticity can be used. For example, water resistant paper may be used. It may be cheap. The inner sheet A that keeps the space inside the mask B is easy to fit on the mask B to be adhered and has the flexibility to fit, so even if the main body A is attached to the face and the main body A is pressed against the face, the nostril pad 13 on the main body A It is easy to breathe because it hits only between the back of the nose and the tip of the nose and does not block both nostrils, and there is a certain space between both nostrils and the mouth.

As shown in FIGS. 1, 2, 8 and 9, the curved shape of the inner sheet A that maintains the space in the mask B is more maintained by connecting the upper curved portion 11 and the lower curved portion 12. Also, the space around the mouth is easy to maintain.

As shown in FIGS. 1 and 8, the nose pad 13 in the main body A protrudes inward from the upper curved portion 11 by the protruding height 22 of the nose pad 13, and the nose pad 13 Due to the lateral length 23, when worn on the mask B, it is more elastic even when pressed between the back of the nose and the tip of the nose, so there is less pressure on the face and the contact is soft, and it is on the main body A. When the nose pad 13 abuts between the back of the nose and the tip of the nose, a space is created at the mouth, making it easier to breathe.
The protruding height 22 of the nose pad 13 may be about 3 to 10 mm for a standard adult. The lateral length 23 of the nose pad 13 may be about 20 to 80 mm for a standard adult. However, the lateral length 23 of the nose pad portion 13 may have a shape that does not block both nostrils and a form in which a gap is formed between the nostrils.

As shown in FIG. 5, the adhesion between the mask B and the inner sheet main body A is achieved by, for example, a strong double-sided tape (bonding means). Other joining means may be single-sided tape, adhesive, or glue. The joining means is not an indispensable configuration, and if the inner sheet A is held on the inner surface of the mask B even if the joining means is provided, the joining means can be omitted.

As shown in FIGS. 1 and 4, the lateral length 18 of the inner sheet A may be less than the lateral length of the mask B to be adhered. For example, for a standard adult, it may be about 90 to 170 mm. The vertical length 20 of the inner sheet A may be, for example, about 60 to 150 mm for a standard adult.

For example, rice glue is used for joining the upper curved portion 11 and the mesh-like sheet S1 and joining the lower curved portion 12 and the mesh-like sheet S2. Further, an adhesive or double-sided tape may be used instead of the rice paste. For example, when glued with rice glue, it can be used safely even if it comes in contact with the face such as the tip of the nose or cheeks, and is kind to the earth. The mesh sheets S1 and S2 are formed by using, for example, sanitary gauze.

When the mask B is directly attached without providing the inner sheet A as in the conventional case, there are the following problems. When wearing Mask B, the space inside Mask B will stick to your mouth if you wear it for a long time, and you will feel stuffy and difficult to talk to. Each time, the center of the mask B may be pulled outward with a finger, or the mask B may be moved up and down to adjust the position. In particular, medical professionals wear the mask B for a long time, and even if the mask B sticks to the mouth, it is difficult to fix the sticking of the mask B with a gloved hand from a hygienic point of view.

As described above, according to this embodiment, the nose pad 13 abuts between the back of the nose and the tip of the nose to form a gap between the user's nose and mouth. It's hard to stick, so it's easy to breathe and it's not difficult to talk. Further, since the window 16 is formed in the upper curved portion 11, it is easy to breathe and the suffocation can be reduced. Further, the nose pad portion 13 is integrally formed with the frames F1 and F2. Further, since the windows 16 and 17 are covered with the mesh sheets S1 and S2, it is easy to breathe and the suffocation can be reduced. Since the mesh-like sheets S1 and S2 are provided on the entire inner surface of the inner sheet A main body, the contact with the face when the inner sheet A main body is attached is improved and the wearing feeling is reduced. Further, since the nose pad portion 13 and the frames F1 and F2 are formed by bending the sheet-shaped blanks B1 and B2, the number of parts can be reduced.

Since the lower curved portion 12 is provided on the upper curved portion 11 so that the posture can be changed, each of the upper curved portion 11 and the lower curved portion 12 can easily fit the face. Further, since the main body A having the upper curved portion 11 and the lower curved portion 12 is provided with windows 16 and 17 at several places, it is easy to breathe and talk, and the back of the nose to the tip of the nose are in contact with each other. The contact between them is soft and there is a sense of stability.

Since the mesh-like sheets S1 and S2 are adhered to the entire upper curved portion 11 and the lower curved portion 12, the upper curved portion 11 and the lower curved portion 12 do not directly touch the face. Even if the inner sheet A that keeps the space inside the mask is adhered to the mask B and attached to the face, the mesh-like sheets S1 and S2 are adhered to the entire inner sheet A, so the contact with the face is soft and the wearing feeling is comfortable. Few.

Inner sheet A, which keeps the space inside the mask, is made of paper, mesh sheets S1, S2, and rice paste, so it can be disposed of as burning garbage and is kind to the earth. In addition, the inner sheet A can be adhered to any kind of mask.
