The utility model shown in FIG. 1, contains a protective screen 1, a unit for fixing the screen on the head in the form of an elastic detachable adjustable headband 2 with a lock 3, made of a transparent polymer material. The headband consists of two identical strips 2. The lock 3 is made in the form of a strip equipped with cutouts 4.

The protective screen 1 in the upper (frontal) part along the entire width has fold lines 5 and notches 6, and the central notch 6 has a notch 4 intended for fixing the headband strips 2. Protective screen 1 in the middle and lower parts (in the area of the cheeks and cheekbones) also has fold lines 5, and along the edges, in the area of the cheekbones, tabs 7 and cutouts 4, designed to fix the tabs 7. The tabs 7 are designed to additionally fix the volume of the protective screen 1.

The fold lines 5 of the protective screen 1 form stiffening ribs and simultaneously form the volume of the screen-mask.

The adjustable headband 2 in the forehead area is equipped with a strip of foam rubber on a self-adhesive base 8.

Collect the protective mask as follows.

The fingers are pressed on the fold line 5 of the blank of the protective screen 1 (Fig. 2) and a three-dimensional (3D) shape of the protective screen is obtained from a flat sheet, with embossed projections and recesses repeating the shape of the face. Then, the tongues 7 are threaded into the cuts 4 located in the cheekbones, and additional stiffeners are obtained (Fig. 3). In the upper part of the protective screen 1 along the fold line 5, the central incision 6 is bent twice inward. The strips of the headband 2 are threaded into the central cutout 4 (one towards the other) and folded over. One of the stripes is directed to the left, and the other to the right. Then, along the fold lines 5, the remaining cuts 6 are folded, placing the headband strips 2 inside them. Due to this fixation, there is no gap between the protective screen 1 and the screen fixing element on the head (Fig. 2).

The strips of the headband 2 are inserted into the cutouts 4 of the lock 3, which are passed through the slot of the lock and are found in the central part of the lock. To adjust the protective screen-mask to the desired size of the user's head, it is necessary to pull the strips of the headband 2, selecting the desired girth, bend the ends of the headband strip and tuck them into the slots (Fig. 4).

For more comfortable use, a soft material is glued onto the adjustable headband 2 (in the forehead area), for example, a strip of foam rubber on a self-adhesive base 8.

The protective screen-mask can be made of polyethylene terephthalate (PET plastic), polycarbonate, polyamide (nylon, nylon), polyvinyl chloride, with a thickness of 0.3 to 1 mm.

All elements of the screen-mask are covered with a protective film. The film is removed from the headband strips, the lock and the notch area during the assembly of the protective screen-mask structure, and from the protective screen before wearing (use). The film is applied to the elements of the product on both sides.

The protective screen 1, the headband strips 2 and the lock 3 are made in one technological process.

An example of a specific implementation.

Any number of blanks can be produced in one technological process. It depends on the format of the nesting machine. The applicant used a KAMACH 1525 RFB large format laser machine. The working area of the machine is 1500x2500 mm. A sheet of material is placed on the working field and cut to the optimal arrangement of elements so that there is less waste.

The screen-mask is made as follows.

Prepare the file for cutting on the machine. Several identical parts or different parts can be produced in a cycle, depending on the optimal location and working format of the machine.

Then the material for cutting is placed on the machine table.

Start the program for cutting parts.

First, at minimum power, fold lines are outlined. After that, the main cutting is carried out at the working power necessary and sufficient for cutting the material.

The cut parts and cuttings are removed from the machine.

Parts are sorted for further use.

The trimmings are prepared for disposal in accordance with the waste management regulations.

Protective screen 1, headband strips 2 and lock 3 were made of PET plastic with a thickness of 0.5 mm.

The mask screen was assembled as described above.

As a result, a tight fit of the screen-mask to the user's forehead was established, which led to an increase in the level of protection of the face and respiratory organs from dust particles, viruses and microbes.

In the manufacture of blanks of the screen-mask, both the length and the width can be varied, depending on the requirements.

It is possible to manufacture screen masks for both adults and children. The number of fold lines (arcuate bends) can be varied, as a result, the design of the screen mask may slightly change.

You can also make a screen mask with a visor (PET plastic). On one side of the visor, cuts are made, and on the other side, tongues. The notches are for securing the headband strips and the tabs for securing the protective shield.

The face shield is reusable. It is disinfected with an antiseptic. Additionally, it can be treated with hydrophobic formulations to prevent fogging.

The claimed utility model provides barrier protection for the face (eyes and respiratory organs) of the user at any tilt and turn of the head, without squeezing the head and without loading the cervical spine. Doesn't interfere with glasses. It also expands the arsenal of existing protective screen masks.

Thus, the claimed utility model can be used with practically any headgear that people need during the cold season, for example, hats. Or in conjunction with hats to protect from the sun's rays, for example, caps, panamas, hats, etc.

A protective screen-mask can be used in conjunction with uniform headdresses, for example, by police officers or traffic police inspectors instead of textile masks on the face.

The mask screen can be used instead of a textile mask that makes breathing difficult by personnel in the food industry, for example in bakeries, where the use of textile masks is even harmful to health due to the high temperature of the production premises.

It can be used by the personnel of catering establishments, for example, in kitchens, as well as by bartenders, waiters.

The proposed improvement of the protective screen-mask allows to reduce the material consumption for its manufacture. It is compact when disassembled.
