The face guard 100 according to the first embodiment to which the present invention is applied will be described with reference to FIGS. 1 to 3.

Here, FIG. 1 is a front view of the guard body 1. Further, FIG. 2 is a front view showing a state in which the mask M is attached to the guard body 1. Further, FIG. 3 is a perspective view showing a state in which the mask M is attached to the guard body 1 and the left and right rubber cords Mb are hung on the left and right ears Ea to attach the guard body 1 to the face.

The face guard 100 includes a guard main body 1, and the guard main body 1 is formed in the form of a sheet having light transmission, and is attached to the face through a mask M at the time of attachment.
As the material of the guard body 1, triacetyl cellulose, stretched polypropylene, vinyl chloride, polyethylene terephthalate and the like can be used.

Of the inner surface A and the outer surface B of the guard body 1, at least the inner surface A may be subjected to anti-fog treatment, so-called anti-fog treatment. The anti-fog treatment of triacetyl cellulose improves the hygroscopicity and moisture release of the guard body 1, that is, the humidity control effect, by processing and modifying the inner surface A of the guard body 1 of the inner surface A and the outer surface B. It enhances and exerts anti-fog effect. In this case, the anti-fog treatment of triacetyl cellulose is different from the treatment or coating of the inner surface A with a chemical, and is composed of triacetyl cellulose alone.

As an anti-fog treatment for triacetyl cellulose, the inner surface A and the outer surface B may be dip-processed. However, since a surface having a strong anti-fog effect and a surface having a weak anti-fog effect can be formed, the strong surface should be the inner surface A.
The anti-fog treatment of stretched polypropylene and vinyl chloride is performed by coating the inner surface A with an anti-fog material.
In polyethylene terephthalate, the inner surface A can be anti-fog treated by providing a hard coat layer whose main material is a UV curable resin.

For example, the material of the guard body 1 is a UV curable resin, and the outer surface B thereof is coated to prevent fingerprints and oil stains. Further, a polyethylene terephthalate film having an ultraviolet ray blocking function may be attached to the outer surface B of the guard body 1. Further, a colored layer may be provided on the outer surface B of the guard body 1 to have a function like sunglasses. In this case, a colored layer is provided on the outer surface B by laminating a coated or colored polyethylene terephthalate.

The guard body 1 has light transmission. That is, the guard body 1 is transparent or translucent, and as described above, even when the inner surface A is subjected to anti-fog treatment and the outer surface B is provided with a colored layer, an appropriate amount of light is transmitted. It has become like.

Since at least the inner surface A of the guard body 1 is anti-fog treated, as will be described later, even if the mask M is covered from the front surface and breathing through the mask M, the inner surface A does not become cloudy or becomes less likely to become cloudy. There is.
As shown in FIG. 1, the guard main body 1 has left and right through holes 10, a mask corresponding portion 20, an eyeball corresponding portion 30, left and right holding portions 40, and a notch portion 50.

The guard body 1 is formed, for example, in a horizontally long rectangular shape with rounded corners. The left through hole 10 and the right through hole 10 are distributed to the left and right with reference to the first center line S1 extending in the vertical direction through the center of the guard main body 1 in the horizontal direction, and the guard main body 1 is arranged. The inner surface A and the outer surface B of the above are communicated with each other. In the example shown in FIG. 1, two through holes 10 are formed on the left side and two on the right side of the first center line S1. The left and right through holes 10 near the first center line S1 correspond to each other, and the distance K1 between the through holes 10 is substantially equal to the left and right width of the small mask M. Further, the left and right through holes 10 far from the first center line S1 correspond to each other, and the distance K2 between the through holes 10 is substantially equal to the left and right width of the large mask M. In the figure, there are two left and right through holes 10, but instead of this, one left and right through hole 10 may be provided, or three or more through holes 10 may be provided.

Each of the through holes 10 has the same shape, and the center N2 in the vertical direction is located below the second center line S2 extending in the horizontal direction through the center in the vertical direction of the guard body 1. ing. As a result, the length of the eyeball corresponding portion 30 described later, which is above the second center line S2, can be sufficiently taken in the vertical direction, and the eye Eye can be reliably covered by the guard body 1. Further, each through hole 10 is formed with a slit 11 extending in the vertical direction and a circular small hole 12 communicating with the slit 11 at the upper end and the lower end thereof. The slit 11 is for passing the rubber cord Mb of the mask M, and the small hole 12 is for substantially positioning the upper portion and the lower portion of the rubber cord 12.
The mask corresponding portion 20 is located between the left and right through holes 10 in the guard main body 1 and is a portion that covers the mask main body Ma from the front surface when the mask M is used.
The eyeball-corresponding portion 30 is located above the mask-corresponding portion 20, and is a portion that covers the left and right eye Eyes from the front surface when the mask M is used.
