Further, by forming the folding curve to be a push bar, the push bar can be formed at the same time as the punching process.

Further, by making the face shield have an antistatic function, it is possible to reduce the adhesion of dust and maintain a good hygiene state.

Further, by forming two notch lines for attaching the attachment on both sides of the upper part of the face shield, the length of the attachment can be easily adjusted. , The cut line can be formed at the same time as the punching process.

Further, the face shield is provided with a front pad on the upper part of the face shield so that a ventilation space is formed in the front pad so that moisture is trapped in the face shield and the face shield becomes cloudy. Can be prevented.

It is a parts diagram which shows one Example of the face shield of this invention. It is explanatory drawing which shows the state which assembled the face shield. It is explanatory drawing which shows the assembled state of the modified example of the face shield.

Hereinafter, embodiments of the face shield of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of the face shield of the present invention.
The face shield 1 forms a laterally extending fold curve 11a under the bendable transparent synthetic resin sheet covering the wearer's face, and is a face shield located below the fold curve 11a. The portion 11 can be bent inward (wearer side).
This makes it possible to prevent droplets of infectious liquids such as blood and saliva from below in addition to the face-to-face direction.

In this case, the face shield 1 can be manufactured by, for example, punching (so-called Thomson processing) a bendable transparent synthetic resin sheet material such as PET resin or polyolefin resin.
Then, in this embodiment, a PET resin sheet having a thickness of about 0.2 mm is used as the material.

Further, a folding curve 12a extending in the vertical direction is formed on both sides of the face shield 1 so as to narrow downward, and the face shield portion 12 located on the side of the folding curve can be bent inward (wearer side). I am trying to do it.
As a result, the face shield 1 can be shaped along the contour of the wearer's face.

In this case, the folding curves 11a and 12a can be formed in a straight line, but in this embodiment, the folding curves 11a and 12a are formed in a convex curve toward the center side of the face shield 1.
By forming the folded curves 11a and 12a into a curved line in this way, the inwardly bent face shield portions 11 and 12 can be stably maintained in that state without returning to their original positions.

Further, the folding curves 11a and 12a can be formed of push bars that have been processed at the same time as the punching process.
Thereby, the folding curves 11a and 12a can be easily formed.

Further, the face shield 1 can be made to have an antistatic function.
The antistatic function can be imparted by, for example, kneading a glycerin fatty acid ester-based material or the like, or coating a conductive polymer-based material or the like.
As a result, it is possible to reduce the adhesion of dust to the face shield 1 and maintain a good hygiene state.
In addition to the antistatic function, the face shield 1 can be provided with necessary functions such as an antifogging function by kneading or coating a material.

Further, two notch lines 13 for attaching the fitting 2 can be formed on both sides of the upper portion of the face shield 1, respectively.
As a result, the length of the mounting tool 2 can be easily adjusted, and the cut line 13 can be easily formed by performing the processing at the same time as the punching process.

The face shield 1 formed in this way has a fitting 2 made of a string-like member made of polyester, natural rubber, or the like attached to the cut wire 13, and has flexibility such as made of soft urethane foam on the upper part. A front pad 3 made of a square rod-shaped body (in this embodiment, a square rod-shaped body having a length of 180 mm, a width of 30 mm, and a height of 35 mm) is attached using an adhesive tape or the like to obtain a product.
Then, at the time of use, the face shield portions 11 and 12 are bent inward along the folding curves 11a and 12a as needed. As a result, the parts 11 and 12 of the face shield can be stably maintained in that state without returning to their original positions.

Further, as in the modified embodiment shown in FIG. 3, a ventilation space 31 can be formed in the front pad 3 mounted on the upper part of the face shield 1.
As shown in this embodiment, the ventilation space 31 has one portion (in this embodiment, a length of 70 mm, a width of 30 mm, and a height) in which the front pad 3 of about 10 to 60 mm is not provided in the middle portion of the front pad 3. Two 35 mm square rods are mounted at intervals of 40 mm) or at multiple locations, or the square rods that make up the front pad 3 are provided with ventilation grooves. It can be formed by using it.
This makes it possible to prevent the face shield 1 from becoming cloudy due to the accumulation of water in the face shield.
