Disposable airtight protection glasses with excellent heat resistance {disposable airtight protection glasses}

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

Generally, viral transmission is transmitted through droplets or through aerosols.

Droplets are a form of contact infection that occurs when people approach and are the most common method of respiratory infections. Influenza or tonsillitis, when a patient coughs or talks, pathogens are released along with small droplets and are inhaled into the respiratory tract together with the air. Tuberculosis, influenza, whooping cough, diphtheria, and pneumonia are spread through droplets.

In particular, aerosols are aerosols with a diameter of 1 μm or less, and are 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 stay in the air for a considerable period of time, being less affected by gravity, so they move farther than droplets.

As such, in order to spread and prevent the virus, there is a method of wearing a mask that can cover the mouth and nose. By wearing such a mask, secretion and penetration of droplets or aerosols are prevented. Wearing a mask is a method that is already widely used, and has the advantage of being easy to wear anytime, anywhere.

However, transmission of the virus occurs through the cornea of the eye as well as the mouth and nose, and the mask has a problem in that it cannot protect the eyes.

Utility Model Registration No. 20-0392963 relates to safety glasses, and is composed of a lens mounted on the front and a body with tightening straps connected to the rear of both sides to adhere to the periphery of the eyes, thereby preventing the penetration of viruses, but most of them are expensive. In addition, it is relatively bulky and heavy, and when used for a long time, it is inevitably inconvenient to perform normal activities, such as causing marks on the face and causing pain due to pressure. In addition, there is a problem in that the lens is deformed at a high temperature and the eyesight is deteriorated because it does not block ultraviolet rays and is weak against heat.

Patent Registration No. 10-2126029 relates to a face shield, which is configured to be worn on the face of the face to protect the face, thereby protecting the face from surrounding contaminants, but is not sealed so that contaminants can easily penetrate It is virtually defenseless against aerosol infection.

In particular, conventional safety glasses or face shields have a problem in that they can be easily pierced and damage eyes when used in industrial sites where sparks can occur. Of course, it is possible to make the lens or face shield thicker so that it is not easily pierced, but the weight becomes heavy and the manufacturing cost increases. There are problems that lead to deterioration of vision, such as eyes getting tired easily.

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

As shown in these drawings, the disposable sealed safety glasses with excellent heat resistance according to the present invention include a flexible transparent window 10 in which an optical PET and a polyimide film are laminated; A cushion member 20 attached along the rear edge of the transparent window 10; An elastic band 30 connected to both ends of the transparent window 10; And a length control unit 40 provided in one section of the elastic band 30 to adjust the length of the elastic band 30; includes

The transparent window 10 is manufactured by laminating one of an optical polyethylene terephthalate (PET) film 10b, an optical polycarbonate, and an optical composite film and a polyimide (PI) film 10a.

In particular, the polyimide film 10a endures a high temperature of 400° C. or higher or a low temperature of 269° C. below zero, is thin, has excellent flexibility, and has excellent heat resistance, chemical resistance, and abrasion resistance, thereby minimizing the occurrence of scratches.

The optical PET film 10b and the polyimide film 10a are manufactured through a dry lamination process. As the adhesive used here, a silicone-based adhesive is used, but heat-resistant silicone is used. At this time, the polyimide film 10a is located on the outside, and the optical PET film 10b is located on the inside. Since the polyimide film 10a is located on the outside, the eyes are protected from external flames or heat, and the polyimide film 10a has a characteristic of being crumbled when damaged, and even if crumbled, it does not flow into the eyes. Of course, even if the polyimide film 10a is crumbled, it remains attached to the optical PET film 10b because it is in a laminated state with the optical PET film 10b.

The manufactured transparent window 10 is manufactured to a thickness of 1 to 1.5 mm, has a property of bending when an external force is applied due to the nature of the material, and unfolds in a flat shape when the external force is removed. Therefore, if it is closely attached to the face, it can be worn appropriately bent according to the curve of the face.

In addition, at least one of an anti-fog coating, an anti-scratch coating, and an anti-fingerprint coating is applied to the inner surface of the transparent window 10 . Therefore, even when touched by hand, fingerprints are not easily smeared, scratches, etc. are not easily generated, and steam does not occur when a temperature difference occurs.

The transparent window 10 is formed with a hole through which the elastic band 11 passes through both ends. The hole 11 is formed in the upper and lower portions, respectively, the upper hole 11 has a cutout groove 12 formed in the upper part, and the lower hole has a cutout groove 12 formed in the lower part, so that the elastic band is formed in the cutout groove 12 ) is inserted through and then caught in the hole (11).

The cushion member 20 is attached along the rear edge of the transparent window 10, and is manufactured to a thickness of 5 to 8 mm, compressed by an external force, and then restored to its original state when the external force is removed. Diene Monomer) and PU (Polyurethane) are used. Since the manufactured material is a fine porous material, it has air permeability. Therefore, while aerosol or dust is filtered out, the temperature difference between inside and outside is minimized to prevent fogging.

Due to the cushion member 20, it is possible to adhere without gaps even in irregular curves of the face, so that the eyes can be completely blocked from external viruses and foreign substances.

On the other hand, the transparent window 10 is provided with a closing member 50 on the front edge. The finishing member 50 may be formed by printing or attaching a film. This finishing member 50 has a function of making the safety glasses more beautiful by designing various patterns, etc., and also a function of preventing the adhesive attached to the rear surface of the transparent window 10 from being exposed to the front of the transparent window 10. .

In addition, a nonwoven fabric 21 may be attached to the inner surface of the cushion member 20 . The non-woven fabric 21 has good air permeability, so it has the advantage of minimizing the temperature difference between the inside and outside of the safety glasses and improving the sense of difference with the skin.

The elastic band 30 has elasticity and is formed in a ring shape. The elastic band 30 is inserted from the front side of the hole 11 on one side of the transparent window 10 and then goes around the back side and exits through the hole 11 on the other side to be hooked. Of course, the opposite is also possible. The elastic bands 30 are each caught on both sides of the transparent window 10 in this way.

The length adjuster 40 is provided in one section of the elastic band 30 and is used for adjusting the length of the elastic band 30 . The length adjustment sphere 40 is a belt-shaped control piece 41; A band hole 42 into which the elastic band 30 is inserted by forming a plurality of through-lines in two lines in the control piece 41; Incision grooves 43 formed in an oblique direction from each band hole 42; It consists of Here, the upper left incision grooves 43 are directed upward in an oblique direction from the band hole 42 to the right, the upper right incision grooves 43 are in an upward oblique direction to the left from the band hole 42, and the lower left incision groove 43 The lower right cut grooves 43 are formed in a downward diagonal direction from the band hole 42 to the right, and the lower right cut grooves 43 are formed in a downward diagonal direction from the band hole 42 to the left.

Therefore, the elastic band 30 is inserted into one of the upper incision grooves 43 and then caught in the upper and lower band holes 42 and then returns to the lower incision groove 43 to maintain the jammed state. Here, the length of the elastic band 30 is increased or decreased according to the position of the band ball 42 to which it is caught.

Figures 6a, 6b is an exemplary view showing a length adjusting device according to another embodiment of the present invention, as shown in the drawing, the elastic band 30 is fixed by the pin 60 or by the folding piece 70 This indicates that fixation can be made.

And, as shown in FIG. 6B, upper and lower holes 11 are formed through both ends of the transparent window 10, and a folded piece 70 folded in half is separately provided, but one side of the folded piece 70 has a hole 11 ) and the pin hole 71 corresponding to the pin hole 71 is formed on the other side, so that the pin 72 penetrates the hole 11 of the transparent window 10 by forming a pin 72 that is press fit into the pin hole 71. to be combined At this time, fixation is made by combining the elastic band 30 in a state in which the inside of the folded portion is wound around.

7 is a perspective view showing a transparent window according to another embodiment of the present invention, as shown in the drawing, a support jaw 15 is formed at the lower end of the transparent window 10 to support a spectacle frame (not shown) By doing so, it is possible to wear glasses after wearing the safety glasses of the present invention.

That is, a supporting jaw 15 bent or curved upward is formed at the lower end of the transparent window 10 . A space is formed between the supporting jaw 15 and the transparent window 10, and has a shape open to the top. Therefore, the spectacle frame is inserted from the top and placed on top. In this way, by supporting the glasses on the supporting jaw 15, there is an advantage that the glasses can be worn after wearing the safety glasses of the present invention.

Since the safety glasses of the present invention having such a structure can be produced by a press or a punching machine, the productivity is very excellent and can be manufactured at a low cost. In addition, it is light in weight and easy to handle, and has the advantage of being able to transport and store a large amount.

8A and 8B are exemplary views illustrating a cushion member according to another embodiment of the present invention, in which a ventilation unit 22 is formed as shown in the drawings to prevent fogging.

That is, a plurality of ventilation parts 22 are formed in the cushion member 20 . As shown in FIG. 8A, the ventilating part 22 facilitates the inflow and outflow of air by forming one part or several parts of the cushion member 20 thin.

Also, as shown in FIG. 8B , the ventilation part 22 may be formed by penetrating any part or several parts of the cushion member 20 . When the ventilation part 22 is penetrated, it is formed only on the cushion member 20 located below the safety glasses to minimize the inflow of foreign substances from the outside. This is because most of the foreign matter falls and floats due to its own weight, so it is not easy to flow in through the ventilation hole located at the lower part.

FIG. 9 is an enlarged cross-sectional view of a main portion of a disposable airtight safety glasses according to another embodiment of the present invention, to supplement the cushion member 20, which is vulnerable to heat, as shown in the drawing.

A tape 80 made of polyimide fiber is attached to the surface of the cushion member 20 . Since the cushion member 20 is vulnerable to heat, there is a problem of being melted and pierced in the event of sparks. By attaching a tape 80 made of polyimide fiber, the cushion member 20 is prevented from melting. Polyimide fibers have excellent heat resistance and excellent dust and particulate filtering functions, thereby preventing fogging caused by a temperature difference by allowing air to flow into the safety glasses while preventing damage to the cushion member 20 .

Since air circulation may be reduced when the tape 80 is attached as described above, through-holes are partially formed in the cushion member 20 to ensure smooth air circulation.
