Mask to block external air inflow and to block fogging}

The present invention not only has a function to block external air from entering when the mask wearer breathes in, but also when the wearer of glasses or goggles wears a mask and exhales, the breath and snort discharged from the glasses or goggles. It relates to a mask that blocks the inflow of external air and blocks fogging, which has a function to block fogging on the lens surface of glasses or goggles by blocking breath and snort from reaching the lenses.

Generally, when a mask is worn on the face, a space is created between the mask and the curved part of the face and the bridge of the nose. Not only has the problem of external polluted air flowing in through this space been pointed out, but also It has been pointed out that the breath and snort discharged from the mouth and nose moves upward, causing fogging on the lens surface of glasses or goggles, which greatly interferes with vision.

To solve this problem, Registered Utility Model Publication No. 20-0422159 discloses a technology consisting of combining a resin core covered with synthetic resin horizontally to the upper part of the mask, but the iron core inserted between the mask and the face part lacks elasticity. There were great limitations in preventing the breath and snort discharged from the mouth and nose from moving upward.

In addition, Registered Patent Publication No. 10-1532558 discloses that a plurality of guide protrusions are formed protruding on one side of the mask main body, and a blocking film is formed on the upper part of the mask main body. However, the shape of the face and the height of the nose protrusion vary depending on the individual. As the surface area varied, there were certain limitations in effectively and precisely blocking the space created in the curved area of the face, and there were inherent inconveniences in the manufacturing process.

In addition, Registered Patent Publication No. 10-1971468 discloses that the upper panel is formed horizontally on the upper part of the mask body, and the breath blocking film is formed vertically downward, and Published Patent Publication No. 10-2020-0056362 It is disclosed that a non-woven fabric layer is formed on the middle inner layer of the upper part of the mask to prevent fogging, and in Patent Publication No. 10-2011-0008148, members such as non-woven fabric or PVC film are placed inside the mask in the shape of a bracket to prevent fogging. Although it has been disclosed to construct a fogging blocking awning, these also have limitations in blocking the upward movement of breath and snort discharged from the mouth and nose.

Meanwhile, Patent Publication No. 20-2020-0000696 discloses a strapless mask having a means for attaching to the user's facial skin at the edge of one side of the mask body, but this is for the purpose of providing a mask without strings. It was only used as a , and had the problem of not being effective in blocking fogging.

The present invention addresses the above-described problem with existing anti-fog masks, by preventing breath and snort discharged from the mouth and nose upward through the space formed between the inner surface of the mask body and the curved portion of the face and bridge of the nose when wearing the mask. The purpose is not only to completely solve the problem of fogging on the surface of the lenses of glasses or goggles due to movement, but also to prevent external exposure through the space formed between the inner surface of the mask body and the curved portion of the face and bridge of the nose. The purpose is to completely solve the problem of polluted air flowing in.

The inventor of the present invention, through long-term in-depth research, has discovered that the breath and snort discharged from the mouth and nose move upward through the space formed between the inner surface of the mask body and the curved portion of the face and bridge of the nose, thereby making the glasses. In addition, not only does it have the function of fundamentally blocking fogging on the lens surface of the goggles, but it also prevents external contaminated air from flowing in through the space formed between the inner surface of the mask body and the curved portion of the face and bridge of the nose. A mask with a complete blocking function was invented.

The mask according to the present invention consists of a plastic film attachment part in which a plastic film with high adhesiveness and flexibility is attached to the uppermost part of the inner surface of the mask body at a constant width in the horizontal direction, so that the upper part of the mask flexibly adheres to the face along the curved part of the face. By having the function of making the mask body, the breath and snort that move upward through the space formed at the curved part between the face and the bridge of the nose are completely blocked by the plastic film adhesive part, fundamentally preventing fogging on the surface of the glasses lens. It not only has a blocking function, but also completely blocks the inflow of external contaminated air through the space formed between the inner surface of the mask body and the curved part of the face and bridge of the nose, blocking the inflow of external air and fogging. It is a blocking mask.

In addition, the mask for blocking external air inflow and blocking fogging according to the present invention may be configured to further include an elastic member blocking portion in addition to the plastic film attachment portion, and the added elastic member blocking portion is a plastic film attachment portion on the inner surface of the mask body. An elastic cushion of a certain diameter or thickness is inserted in the horizontal direction at the bottom, so that it protrudes from the inner surface of the mask by the diameter or thickness of the cushion inserted inside, so that the inner surface of the mask body is in close contact with the curved part of the face, so that the bridge of the nose is protected. Not only can external air flowing in through the curved space between the face and the face and breath and snort moving upwards be primarily blocked by the elastic member blocking portion, but in addition, the protruding elasticity of the elastic member blocking portion Even after being primarily blocked by the cushion, some residual outside air and breath and snort that move to the top are completely blocked secondarily by the plastic film adhesive, thereby more completely blocking fogging on the surface of the glasses lens. It is a mask that blocks external air inflow and blocks fogging.

The specific configuration will be described below.

The mask for blocking external air inflow and fogging according to the present invention has a plastic film adhesive portion formed horizontally on the mask body and the inner surface of the mask body, and a plastic film adhesive portion formed horizontally on the mask body but formed at the upper end in the vertical direction, and is shaped by external force. This can be configured to include a changeable plastic fixing member and a mask string.

In addition, in order to more completely block external air inflow and fogging, it can be configured to include an elastic member blocking part formed horizontally on the mask body in addition to the plastic film adhesive part.

To explain in more detail, it may be comprised of an inner surface of the mask body and an outer surface of the mask body.

Additionally, the mask body may be configured to include one or two or more mask body filter surfaces.

In addition, the plastic film adhesive portion is formed in the horizontal direction perpendicular to the direction from the nose to the eyes (glasses direction; vertical direction) to block the inflow of external air on the inner surface of the mask body and block breathing and snorting, and is located at the upper end of the vertical direction. It can be formed into a long strip shape.

In addition, in addition to the plastic film adhesive part, it may be configured to further include an elastic member blocking part. This elastic member blocking part is made of a material having a cushion and is formed horizontally on the inner surface of the mask body or between the inner surface of the mask main body and the elastic member blocking part. It can be formed horizontally between the outer surface of the mask body or horizontally between the inner surface of the mask main body and the filter surface of the mask main body.

Meanwhile, the present inventor focused on the fact that it is very important for the plastic film to be completely adhered to the face in order to block the inflow of external air and completely block breathing and snorting by the plastic film adhesive portion, and through repeated research, The present invention was completed by revealing that in order to improve the adhesion of a plastic film, the type, flexibility, rigidity, thickness, specific gravity, etc. of the plastic film must be comprehensively considered.

First, with regard to the type of plastic film, it was revealed that common plastic films such as polyethylene, polypropylene, and polybutylene can be used and are not particularly limited by type.

Second, it was revealed that the thickness and specific gravity of the plastic film are very important factors, and that the most important influence on adhesion is flexibility, which is determined in conjunction with the combination of thickness and specific gravity.

According to the above research results, when considering the adhesion, flexibility and durability of the film of the plastic film adhesive part, it is preferable that the thickness of the film is 3 to 40㎛, and the specific gravity of the film is 0.880 to 0.939 in the case of polyethylene film. It was found that flexibility and durability are desirable for anything within the range.

The mask that blocks the inflow of external air and blocks fogging according to the present invention prevents the breath discharged from the mouth and nose due to the space between the inner surface of the mask body and the curved portion of the face and bridge of the nose when wearing the mask, which is a problem with existing anti-fog masks. It not only has the effect of solving the problem of fogging on the surface of the lenses of glasses or goggles due to the movement of snort upward, but also has the effect of solving the problem of fogging the surface of the lenses of glasses or goggles. It also has the effect of completely solving the problem of polluted air flowing in, and the specific effects are as follows.

That is, first, the plastic film attachment part is formed by attaching a highly adhesive and flexible plastic film to the top of the inner surface of the mask body at a constant width in the horizontal direction, so that the upper part of the mask is flexibly adhered to the face along the curved part of the face. By having this, the outside air that flows in through the curved space between the bridge of the nose and the face, as well as the breath and snort that moves to the upper part, are completely blocked by the plastic film adhesive part, which has the effect of blocking the inflow of outside air and fogging the surface of the glasses lens. This represents a fundamentally blocking effect.

Second, in addition to the effect of the plastic film attachment part, the elastic member blocking part, which may be additionally included, is configured to insert an elastic cushion of a certain diameter or thickness in the horizontal direction on the upper part of the mask body, so that the diameter of the cushion inserted inside is By protruding from the inner surface of the mask body by the thickness of the mask, it has the function of allowing the mask to adhere closely to the curved part of the face, so that external air flowing in through the space part of the curved part between the bridge of the nose and the face and the breath and snort that move to the top are prevented by elasticity. After being primarily blocked by the blocking part, some residual incoming outside air and breath and snort moving to the top are completely blocked secondarily by the plastic film adhesive part. It not only has the effect of blocking the inflow of external air, but also more completely blocks fogging on the surface of the eyeglass lenses.
