Hereinafter, an anti-fog mask tool as an embodiment of the mask tool of the present invention will be described with reference to the drawings.

In the present embodiment, as an example, a case where the anti-fog mask tool is attached to a generally commercially available disposable mask will be described.

The mask to which the anti-fog mask tool can be attached is not limited to a disposable mask, and can be attached to any ordinary mask.

FIG. 1 (a) is a schematic perspective view showing a schematic configuration of the anti-fog mask tool 100 of the present embodiment, and FIG. 1 (b) shows the anti-fog mask tool 100 shown in FIG. 1 (a). It is a schematic side view when viewed from the direction of arrow A, and FIG. 1 (c) is a perspective view of a spacer protrusion 112 provided on the anti-fog mask tool 100 shown in FIG. 1 (a).

Further, FIG. 2 shows a state before the anti-fog mask tool 100 shown in FIG. 1A is attached to the commercially available disposable mask 1, and shows the inner surface side (that is, the side in contact with the face) of the disposable mask 1. It is a schematic perspective view.

Further, FIG. 3 shows a state in which the anti-fog mask tool 100 shown in FIG. 1A is attached to a commercially available disposable mask 1, and shows an outline of the inner surface side (that is, the side in contact with the face) of the disposable mask 1. It is a perspective view.

As shown in FIGS. 1A to 3A, the anti-fog mask tool 100 of the present embodiment can be arranged along the inner surface of (1) the upper side of the mask body 2 of the disposable mask 1 and is non-ventilated. The first sheet-like member 110 made of substantially rectangular silicon, which is flexible and flexible, and (2) the upper end 111 of the first sheet-like member 110 are connected by an adhesive, and a protrusion for a spacer, which will be described later. It can be plastically deformed roughly along the shape of other faces including the nose covered with the mask body 2, which is maintained at a predetermined distance from the first sheet-like member 110 by 112 (see FIG. 1 (c)). The second sheet-like member 120 made of non-breathable substantially rectangular silicon and (3) the upper end 111 of the first sheet-like member 110 are connected by an adhesive, and the hooking gap 131 (FIG. 1 (b), A substantially rectangular silicon fixing member 130 that projects downward while maintaining (see FIG. 2) is provided, and the upper end edge 2a of the mask body 2 is provided by utilizing the predetermined gap of the fixing member 130. The first sheet-shaped member 110 and the second sheet-shaped member 120 can be attached to and detached from the inner surface side of the mask main body 2 by hooking the mask body (see FIGS. 2 and 3).

Further, as shown in FIGS. 1A to 1C, the left-right width of the first sheet-like member 110 is on the surface of the first sheet-like member 110 on the side facing the second sheet-like member 120. A plurality of hemispherical spacer protrusions 112 having different heights are formed except for the vicinity of the center of the direction (that is, the portion corresponding to the back of the nose 21 and the vicinity of the left and right sides thereof).

The silicon sheet-like member of the present embodiment is formed by molding silicon rubber into a thin plate, but is not limited thereto.

Further, the second sheet-shaped member 120 of the present embodiment may be plastically deformed along the shape of the nose or cheek to some extent, and does not need to be plastically deformed along the shape of the nose or cheek without any gap. ..

Furthermore, the spacer protrusion 112 is arranged at a position closer to the height of the spacer protrusion 112 arranged at a position far from the connecting portion between the first sheet-shaped member 110 and the second sheet-shaped member 120. It is integrally molded with the first sheet-shaped member 110 at different heights so as to be higher than the height of the spacer protrusion 112 (see FIG. 1B).

Here, the left-right widths of the first sheet-shaped member 110, the second sheet-shaped member 120, and the fixing member 130 are the same, but the vertical widths of the first sheet-shaped member 110 are the longest, and the fixing member 130 has the longest vertical width. The shortest, the second sheet-like member 120 is in the middle.

Specifically, the vertical width of the first sheet-shaped member 110 of the present embodiment is set to a length that covers the nose back 21 and the nose tip 22 (see FIG. 4A) of the adult nose. There is. The vertical width of the second sheet-shaped member 120 of the present embodiment is set to a length that covers the nose back 21 (see FIG. 4A) of the adult nose. However, it is not limited to this.

Further, the horizontal width and the vertical width of the anti-fog mask tool 100 are set shorter than the horizontal width and the vertical width of the mask main body 2.

As a result, the left and right ends and the lower end of the anti-fog mask tool 100 do not protrude from the mask body 2, and the fixing member 130 protruding downward from the upper end of the mask body 2 has a strip shape with a short vertical width. Since it is a member, it gives a clean impression on the outside and is excellent in design.

According to the above configuration, when the anti-fog mask tool 100 is attached to the mask body 2 of the disposable mask 1, the user can use the left and right sides of the first sheet-shaped member 110 of the anti-fog mask tool 100 as shown in FIG. The center position of the width is aligned with the center position of the left and right width on the inner surface side of the mask body 2 of the disposable mask 1, and the hooking gap 131 between the fixing member 130 and the first sheet-shaped member 110 is provided. By inserting the upper end edge portion 2a of the mask main body 2, the fixing member 130 is hooked on the upper end edge portion 2a of the mask main body 2.

It is assumed that this user wears eyeglasses 40 (see FIGS. 4 (a) and 4 (b)).

As a result, the anti-fog mask tool 100 can be easily attached to the mask main body 2, and the anti-fog mask tool 100 attached to the mask main body 2 can be easily removed by the user lifting it upward. Can be done.

The fixing member 130, including the connecting portion with the first sheet-shaped member 110, has a higher hardness than the first sheet-shaped member 110 and the second sheet-shaped member 120 and is not easily deformed, so that the fixing member 130 is cloudy. After the preventive mask tool 100 is attached to the mask body 2, it does not easily fall off during use.

Further, in this way, the user attaches the anti-fog mask tool 100 to the mask main body 2, puts the mask main body 2 on the face, hangs the left and right ear hooks 3 on the ears, and then puts the mask main body. By pressing with both hands from the central portion of 2 to the left and right sides, the central portion 121 of the second sheet-shaped member 120 is passed through the central portion of the first sheet-shaped member 110 in which the spacer protrusion 112 is not formed (FIG. 2). 3. (See FIG. 4A) is plastically deformed around the back of the nose 21 around the back of the nose by pressing with both hands, and the left and right side portions 122L and 122R of the second sheet-like member 120 (FIG. 3, FIG. 3). FIG. 4A) is plastically deformed roughly along the shape of the upper cheek 31.

As described above, the height of the spacer protrusion 112 near the upper end edge 2a of the mask body 2 is low, and the spacer protrusion 112 is not formed in the central portion of the first sheet-shaped member 110. Therefore, the upper end edge 2a of the mask body 2 does not protrude significantly forward on both the left and right sides of the portion covering the back of the nose 21, so that the mask body 2 does not interfere with the eyeglasses 40 worn by the user.

Next, with reference to FIGS. 4 (a) and 4 (b), the flow of exhaled breath in the state of use of the disposable mask 1 to which the anti-fog mask tool 100 is attached will be described.

FIG. 4A is a schematic vertical section of the anti-fog mask tool 100 and the mask body 2 on the back of the nose 21 for explaining the flow of exhaled air in the use state of the disposable mask 1 to which the anti-fog mask tool 100 is attached. It is a top view.

Further, FIG. 4B shows fogging when the area around the left side of the face is viewed from the rear left side of the face to explain the flow of exhaled breath in the state of use of the disposable mask 1 to which the anti-fog mask tool 100 is attached. It is a schematic perspective view of the preventive mask tool 100 and the disposable mask 1.

In FIG. 4A, in order to make the drawing easier to see, the vertical cross section of the anti-fog mask tool 100 on the back of the nose 21 is shown by a thick solid line, and the vertical cross section of the mask body 2 is shown by a thin solid line. The central portion 121 and the left portion 122L of 120 are shown by a chain double-dashed line. Further, in FIG. 4B, in order to make the drawing easier to see, the anti-fog mask tool 100 is shown by a thick solid line and a broken line, and the mask body 2 and the ear hook portion 3 are shown by a two-dot chain line.

The exhaled breath 50 (see the arrow in FIG. 4A) emitted from the user's nose or mouth cannot pass through the non-breathable first sheet-shaped member 110 and the second sheet-shaped member 120, and thus the nose. It mainly passes through the gap 60 (see FIGS. 1 (b), 4 (a), and 4 (b)) formed by the plurality of spacer protrusions 112 arranged on the left and right sides of the back portion 21 in the left-right direction. , The left and right edge portions 2L and 2R of the mask main body 2 (see FIGS. 3 and 4B) go out of the mask main body 2 through gaps and the like. As a result, it is possible to prevent the exhaled air from leaking from the upper part of the mask body 2 to the outside, so that it is possible to prevent the spectacles 40 from becoming cloudy due to the exhaled air.

Further, since the dustproof function of the mask body 2 is strengthened by the intervention of the first sheet-shaped member 110, it is possible to further prevent pollen, dust, viruses and the like from invading the nose and mouth.

Further, as shown in FIG. 4A, the second sheet-shaped member 120 of the present embodiment is plastically deformed into a shape substantially along the nose, cheeks, and the surrounding facial parts, and is described above. Since the gap 60 (see FIG. 4B) is secured so that the exhaled breath can easily pass through, there is a slight gap between the second sheet-like member 120 and the nose, cheeks, and the surrounding facial parts. Even if it occurs, it is suppressed that the exhaled air leaks from the upper part of the mask body 2 to the outside through the gap.

As a result, the exhaled breath 50 (see the arrow in FIG. 4 (a)) emitted from the user's nose or mouth is mainly the left and right both end edges 2L and 2R of the mask body 2 (see FIGS. 3 and 4 (b)). Since it is possible to prevent the exhaled air from leaking out from the upper part of the mask body 2 by going out of the mask body 2 through the gap portion or the like generated in the mask body 2, it is possible to prevent the spectacles 40 from becoming cloudy due to the exhaled air.

Further, since the anti-fog mask tool 100 of the present embodiment is made of a flexible silicon member, it is excellent in oil resistance, heat resistance, etc., can be heat disinfected and washed with water, and is a mask tool. It is also excellent in ensuring hygiene.

Here, FIG. 7A is a perspective view of the fourth anti-fog mask tool 400 configured by providing the second spacer member 410 between the first sheet-shaped member 110 and the second sheet-shaped member 120. FIG. 7B is a perspective view of a fifth anti-fog mask tool 500 configured by providing a third spacer member 510 between the first sheet-shaped member 110 and the second sheet-shaped member 120. FIG. 7 (c) is a perspective view of a sixth anti-fog mask tool 600 configured by providing a fourth spacer member 610 between the first sheet-shaped member 110 and the second sheet-shaped member 120.

Further, the second spacer member 410, the third spacer member 510, and the fourth spacer member 610 shown in FIGS. 7 (a) to 7 (c) have a property of being plastically deformable substantially along the shape of the nose. The case of the configuration has been described, but the present invention is not limited to this, and for example, the parts of the second spacer member 410, the third spacer member 510, and the fourth spacer member 610 that touch the nose are matched to the shape of a standard adult nose. It may be dented in advance. As a result, the second sheet-like member 120 of the fourth anti-fog mask tool 400, the fifth anti-fog mask tool 500, as compared with the configuration in which the nose shape of a standard adult is not dented in advance. And the sixth anti-fog mask tool 600 becomes more familiar with the shape of the user's nose and upper cheek.

Further, in the above embodiment, a spacer protrusion 112 (see FIG. 4B) is provided on the first sheet-shaped member 110 so that the exhaled breath 50 emitted from the nose or mouth flows in the left-right direction. The provided configuration or a spacer member 310 or the like between the first sheet-shaped member 110 and the second sheet-shaped member 120 (FIGS. 6 (a) to 6 (d), 7 (a) to 7 (c)). ) Is provided, but the configuration is not limited to this. For example, the first sheet-shaped member 110 can secure a space between the cheek and the exhaled breath 50 emitted from the nose and mouth in the left-right direction. It may be preformed into a shape having such a bulge. In the case of this configuration, it is not necessary to provide the spacer protrusion 112, the spacer member 310, the second spacer member 410, the third spacer member 510, or the fourth spacer member 610 described above.

Further, in the above embodiment, the case where the left-right width of the anti-fog mask tool 100 is set shorter than the left-right width of the mask main body 2 has been described, but the present invention is not limited to this, and for example, the anti-fog mask tool 100 The left-right width of the mask main body 2 may be the same as the left-right width of the mask main body 2, or may be set longer than the left-right width of the mask main body 2.

Further, in the above embodiment, the vertical width of the second sheet-shaped member 120 is constant from the left end to the right end so as to cover the nose back 21 (see FIGS. 1 and 3) of the adult nose. The case where the vertical width is set to be substantially rectangular in the front view has been described, but the present invention is not limited to this. For example, the second sheet-shaped member 120 is in the horizontal width direction of the second sheet-shaped member 120. It has the shortest vertical width in the central part, and has a substantially inverted V-shaped notch that is cut out so as to roughly follow the shape of the nose centering on the part corresponding to the back part 21 of the nose. It may have a substantially rectangular shape.

According to the mask tool of the present invention, it can be attached to and detached from a conventional mask, and by attaching it to the conventional mask, it exerts an effect that the glasses are less likely to fog. It is useful as a mask tool to be used.
