Abstract

The present invention relates to a mask for the prevention of respiratory diseases due to yellow dust and to protect the health of the worker. Conventional masks do not adhere closely along the curved surface around both cheeks and nose around the mouth of the face, there is a problem that the dust is sucked into the body during the breathing process.

Therefore, in the mask 10 having the wrinkled portion 14 grounded on the front surface, both side portions of the wrinkled portion 14 are formed in the half moon-shaped sideline 20 or the straight side-line 21 in the form of half brackets. By attaching the filter paper 11 of the multi-layer structure to each other, the lifting phenomenon with respect to both sides of the mask 10 is prevented.

Description

The mask for preventing get loosed the side}

The present invention relates to a mask. Masks are worn to protect workers' health in chemical plants with high toxic gas emissions, metal smelting sites where metal powder and welding fumes are generated, or in paper-related or textile mills. In addition, in a food production line, a worker wears a mask to make hygienic food, or a semiconductor lab (or a semiconductor manufacturing site) wears a mask to minimize dust generation to improve the quality of a semiconductor. On the other hand, in recent spring, due to the yellow dust blowing from China, the general public is wearing a lot to prevent respiratory diseases.

As such, wearing masks to prevent respiratory diseases caused by yellow dust and protecting workers' health is increasing. However, when wearing a conventional mask, the mask is closely adhered to both cheeks and the curved surface of the nose area around the mouth of the face. In reality, many point out that the structural improvement of the mask is required due to the problem that is not solved.

Of course, in order to prevent dust from being sucked into the body through the gap between the contour of the nose and the mask, a free bending wire 17 is inserted into the upper edge 12 of the mask 10 to face the nose. Although close to the contour, the problem of dust inflow through the gap between the curved contour of both balls and the sides of the mask remains a challenge.

Therefore, the present invention was devised to contain dust introduced into the gap between the both side portions of the mask 10 and the curved contours of both cheeks of the wearer, and the filter paper 11 is grounded several times to wrinkle the front surface of the mask. (14) is provided, and both side portions of the pleats 14 provide a mask finished with a half moon bracket side line (20, side line) or a straight side line 21 to prevent dust inflow source I would like to.

Specific problem solving means of the present invention in the mask (10) having a grounded corrugated portion 14, both side portions of the corrugated portion (14) in the form of a half moon bracket side line (20) or straight side line (21) As a result, the multi-layered filter papers 11 are attached to each other so that the lifting phenomenon on both sides of the mask 10 is prevented.

Due to the present invention, as the lifting phenomenon of the mask is blocked at the source side of both side finishes 13 of the mask 10 in contact with the curved contour portions of both cheeks of the face, dust and other dusts, including yellow dust, are not introduced into the respirator. In addition, compared to the conventional mask side side 13 is omitted, there is a side effect of increasing the profitability due to cost reduction.

Hereinafter, a preferred embodiment that can achieve the object of the present invention will be described as compared with the prior art.

1 is a perspective view of a separation and engagement of a conventional mask, in which the pleats 14 are formed on the filter paper 11 as shown in FIG. The corrugations 14 are formed by folding several times in order to increase the face cover area of the mask and reduce the volume in the distribution step.

The filter paper 11 is usually formed of a multi-layered structure of the inner, inner and outer skin, and the upper and lower edges 12 of the filter paper 11 are grounded and heat-sealed, and a bending wire 17 is inserted between the grounded papers. . The bending wire 17 is a plastic material that can be bent freely to be in close contact with the bend of the nose to enhance the adhesion when the mask 10 is worn and to enhance the dustproof effect.

On the other hand, both sides of the filter paper 11 is added to the side finish (13) and then heat-sealed so that the fusion unit 16 is formed by the ultrasonic wave, the ear band 15 is also attached to the heat-sealed method through the ultrasonic wave.

The conventional mask configured as described above is worn by unfolding the wrinkles 14 up and down when worn, and extending from the nose to the lower part of the chin. As mentioned above, the curved surface of the nose is masked through a freely bent wire 17. By bringing in close contact with (10), the inflow of dust is blocked.

However, as the lifting of the mask occurs at both side finishing 13 portions of the mask 10 in contact with the curved contour portions of both balls, dust and dusts, such as yellow dust, are introduced into the respiratory tract through the gap between the declining portions. There is.

Thus, as shown in Figs. 2 and 3, the side finishes 13 of the mask 10 are removed, and instead, half-sided side lines 20 or side-side lines in the form of half-brackets are formed on both sides of the pleats 14 instead. By heat-sealing the 21 through ultrasonic waves, both sides of the mask 10 will be lifted.

That is, FIG. 2A is a front view of the mask on which the half moon side line 20 is formed according to the present invention, and as shown in FIG. 2A, the half moon side line 20 is formed at both sides of the mask 10. Heat-sealed in the form of a half-bracket, the inflection point of the half-moon sideline 20 is formed so as to be located in the center of the filter paper 11, unfolds the wrinkles 14 to expand and expand to wear the mask 10 3, the side portion of the mask 10 naturally deforms from the straight shape to the curved portion 30 as shown in FIG. 3.

This is because the ends of the pleats 14 on both side portions of the mask 10 overlap each other during the development of the mask, and the curved portion 30 having excellent adhesion is naturally formed.

Conventionally, the side finishes 13 on both sides of the mask, due to the structural problem that the ends of the wrinkles 14 do not overlap each other, the natural curved portion 30 is not formed as in the present invention, causing side lateral lifting. . However, this aspect is lifted through the present invention.

FIG. 2B is a front view of the mask on which the straight sideline 21 is formed according to the present invention, and FIG. 2B shows ultrasonic waves on both sides of the mask 10 by the straight sideline 21. As it is thermally fused through, when the wrinkles 14 are unfolded and deployed to wear the mask 10, the ends of the wrinkles 14 overlap each other, and the curved portion 30 having excellent adhesion is naturally formed.

As described above, the side portion of the mask 10 according to the present invention having the curved portion 30 formed while overlapping the ends of the wrinkles 14 naturally adheres along the curved contours of both cheeks of the wearer's face, including yellow dust. The ingress of dust into the respiratory tract is blocked.

Figure 4 is a perspective view showing the wearing state of the side lifting prevention mask according to the present invention, the present invention has a side effect (13) is omitted compared to the conventional mask, there is only a side effect of increasing profitability due to cost reduction Rather, it is suitable for the well-being era of pursuing the well-being and happiness of the mind and body by blocking the source of dust introduced into the side of the mask.

As described above, although the preferred embodiment according to the present invention has been illustrated and described, the present invention is not limited to the above embodiment. That is, in the present invention, the half-moon side line 20 or the straight side line 21 is a mask that is heat-sealed through the ultrasonic wave, but this is to omit the side finish 13 to form a curved portion 30 excellent adhesion The vandal type side line 20 or straight side line 21 is formed only for the purpose of the present invention, even if it is replaced by a sewing method or other finishing means such as high frequency.
