Description

Disposable airtight protection glasses with excellent heat resistance

The present invention relates to disposable sealed safety glasses, and more particularly, to disposable sealed safety glasses having excellent heat resistance that can be manufactured inexpensively, can be discarded after use without burden, and are particularly resistant to heat to protect eyes from sparks or flames.

Viruses are usually transmitted through droplets or through aerosols.

Droplet is a form of contact infection caused by person-to-person contact and is the most common method of respiratory infections. As with influenza or tonsillitis, pathogens are released along with small droplets when a patient coughs or during a conversation and is transmitted through inhalation into the respiratory tract along with the air. Tuberculosis, influenza, whooping cough, diphtheria, and pneumonia are transmitted through droplets.

In particular, an aerosol is an aerosol with a diameter of 1 μm or less, which is smaller than droplets produced when coughing or sneezing. Droplets fall to the ground at a relatively early time due to gravity, but aerosols are light and move farther than droplets because they are less affected by gravity and stay in the air for a considerable period of time.

As such, there is a method of wearing a mask that can cover the mouth and nose to prevent the spread and prevention of the virus. Wearing such a mask prevents the secretion and penetration of droplets or aerosols. Wearing a mask is already widely used and has the advantage of being easily worn anytime, anywhere.

However, the virus spreads not only through the mouth and nose, but also through the cornea of the eye, but there is a problem that the mask cannot protect the eyes.

Registered Utility Model No. 20-0392963 is about safety glasses, and consists of a lens mounted on the front, and a body with drawstrings connected to both sides of the rear to keep it close to the periphery of the eyes, thereby preventing the penetration of viruses, but most of them are expensive. It is relatively bulky and heavy, and when used for a long time, it inevitably causes discomfort in daily activities, such as the occurrence of marks and pain on the face due to pressure. In addition, there is a problem in that the lens is deformed at a high temperature because it does not block UV rays and is weak to heat, and thus vision deteriorates.

Registered Patent Publication No. 10-2126029 relates to a face shield, and by being worn on the face of the face to protect the face, it is possible to protect the face from surrounding contaminants, but as it is not sealed, the penetration of contaminants is made easily It is virtually defenseless against aerosol infection.

In particular, there is a problem in that the conventional safety glasses or face shield can be easily pierced when used in an industrial field where sparks can occur and damage to the eyes. Of course, it is possible to make the lens or face shield thick so that it cannot be easily penetrated, but the weight becomes heavy and the manufacturing cost increases. There is a problem that leads to deterioration of eyesight, such as easy fatigue of the eyes.

Therefore, there is a need for disposable sealed safety glasses with excellent heat resistance that can be easily worn anytime, anywhere and discarded without burden while being inexpensive like a disposable mask.
