Description

mask {wireless mask}

The present invention relates to a mask, and more particularly, to a mask in which the upper end in contact with the bridge of the nose is folded in two stages and can be adhered to the wearer's face such as the bridge of the nose, cheeks, and chin without a nose wire to improve airtightness. will be.

In general, a mask prevents foreign substances or droplets generated from the human respiratory system from splashing around, protects the wearer from dust or harmful environmental substances generated at industrial sites, and removes particulate harmful substances such as yellow dust or fine dust, bacteria or It is widely used for purposes such as medical masks for the purpose of protecting the wearer from viruses and preventing infection during treatment, treatment or surgery.

Masks need to secure airtightness by increasing adhesion in order to block outflow and inflow of foreign substances or droplets in the air, which is a basic function. Conventional masks secured such adhesion and airtightness by installing a nose piece. At this time, the nose piece can simultaneously serve to create a predetermined space between the mouth and the mask by bending the middle portion like a bow when wearing the mask.

As a prior art of such a mask, Registration Patent No. 10-2273386 covers the wearer's mouth and nose and has a rectangular mask body with a nose wire embedded in the upper part and attached to both sides of the mask body, respectively, so that the mask body can be worn when worn. In the dental mask composed of an ear band for preventing departure from the face, the dental mask is a rectangular nose cover having a certain width at the lower part of the part where the nose wire is embedded in the inner upper part of the mask body A dental mask having a dripping and anti-fogging function is shown, characterized in that the nose bridge is attached, and both sides and top of the nose cover are fused and attached to the mask body, and the nose cover is formed in two layers. In the prior art, since the nose cover is worn after opening it with a hand, germs in the hand may be transferred, resulting in a risk of infection, and the side part covering the wearer's cheek is lifted by the nose cover There was a problem that adhesion could not be achieved.

On the other hand, the nose piece is in the form of an iron core coated with synthetic resin, and may cause safety accidents when used and may be a major cause of environmental pollution when discarded after use.

That is, waste mask waste is a major cause of environmental pollution, and about 129 billion waste masks are thrown away every month around the world, most of which are incinerated, buried, or flowed into the sea, threatening marine life. Filters and non-woven fabrics, which are the main raw materials of masks mass-produced through the thermal fusion bonding process, are plastics called polypropylene. If buried in the ground, they take hundreds of years to decompose. It can also be absorbed by the human body.

However, currently, waste masks cannot be separated and discharged as recyclables, and one of the reasons why waste masks cannot be separated and discharged as recyclables is a nose piece made of iron core. Therefore, a technology capable of replacing the iron core nose piece is required.

It is a side view shown, FIG. 4 is a plan view showing a state in which the mask according to the present invention is worn, and FIG. 5 (a) to (c) are views showing another embodiment of the mask according to the present invention.

The present invention relates to a mask (100) in which the upper end in contact with the bridge of the nose is folded in two stages and can be adhered to the wearer's face such as the bridge of the nose, cheeks, and chin without a nose wire to improve airtightness. 1 to 4, the mask body 110 is formed with wrinkles 111 convex outward when deployed vertically, and is provided on both left and right ends of the mask body 110 to protect the user's ears. It includes a pair of hanging straps 120 that are wound, but is folded in two stages to the inside of the upper end of the mask body 110 to form an upper contact portion 112 in close contact with the face.

In more detail, the mask body 110 may have a multi-layer structure including at least one of various materials such as woven paper, non-woven fabric, or synthetic resin fiber. In the case of an embodiment, the multi-layers constituting the mask body 110 may have a three-layer structure in which an outer fabric, a filter, and a lining are stacked.

However, the present invention is not limited thereto, and may further include other layers if necessary, and may be variously changed to have the same color or different colors.

When viewed from the front, the mask body 110 has a substantially rectangular shape, and an edge of the mask body 110 is heat-sealed or sewn to combine the outer fabric, the filter, and the seal.

In addition, ends of the lanyard 120 may be fixedly coupled to each of the four corners of the mask body 110 by thermal fusion or sewing.

In addition, the mask body 110 is folded at a predetermined width in multiple stages in the transverse direction to form wrinkles 111 at both ends of which are fixed by thermal fusion or sewing. It is formed in a form in which wrinkle grooves 111a are formed downward based on the outer side, and when the mask 100 is developed up and down, the wrinkles 111 widen and are deformed into a convex shape to the outside, so that the wearer's face from the bridge of the nose to the lower jaw To be configured to wrap, such a wrinkle portion 111 is a well-known configuration and is not claimed in the present invention, so a detailed description thereof will be omitted.

On the other hand, the upper contact portion 112 is naturally deformed in shape when the mask body 110 is developed vertically to wear the mask 100, and is adhered to the face without a conventional nose wire, so that it does not flow down arbitrarily when worn, and the mask (100) and the wearer's face by increasing the airtightness, it is possible to prevent the rise of breath, and there is an effect of preventing the inflow of splashes from the outside.

In addition, as described above, since the mask 100 according to the present invention is manufactured without a nose wire, the cost of purchasing the nose wire is not required, and the manufacturing process is reduced because there is no nose wire insertion process, thereby reducing the manufacturing cost. It is possible to incinerate without separate discharge when discarding after use, which has an effect of reducing environmental pollution.

At this time, as shown in FIG. 3, the upper contact portion 112 is integrally formed to extend from the upper end of the mask body 110, and is primarily folded downward toward the inside of the mask body 110 to form a primary folded portion. (112a) is formed, and is folded in two stages to form a second folded portion (112b) by being secondarily folded toward the inside and upward by half the height of the first folded first folded portion (112a).

Since the left and right ends of the upper contact portion 112 folded in two stages are coupled to the mask body 110 by thermal fusion or sewing, a first opening portion 112c is formed at the lower portion and a second opening portion is formed at the upper portion. The portion 112d is formed so that the upper contact portion 1120 can closely cover the bridge of the nose without a nose wire.

Therefore, the process of manufacturing and connecting the upper contact portion 112 separately is eliminated, and simply folds in two stages and combines both ends of the left and right parts, thereby simplifying manufacturing and reducing material costs.

So, when the mask body 110 including the upper contact portion 112 is unfolded vertically to wear the mask 100, the wrinkles 111 are spread outward, and the mask body 110 is convex outward in the vertical and downward directions. It is deformed to form an arc shape in both the left and right directions. At this time, the upper contact portion 112 is also deformed in a form corresponding to the facial shape while maintaining appropriate elasticity when deployed, so that it can adhere to the face of the wearer's nose, cheek, etc. do.

That is, due to the arc-shaped deformation of the mask body 110 in the left and right directions, the central part of the upper contact part 112 is convex outward and adheres to the bridge of the nose, and the center part of the upper contact part 112 and both left and right ends The gap is convex in the inward direction, that is, in the direction of the wearer's face, and as shown in FIG. 4, it comes into close contact with the face corresponding to the front cheek from the bridge of the nose.

The deformation of the upper contact portion 112 is made only by the user's operation of unfolding the mask body 110 including the upper contact portion 112 upwards and downwards without a separate operation, and the upper contact portion 112 is in close contact with the face. There is no need for additional contact to transform into a shape, and by minimizing the wearer's hand contact, there is an effect of minimizing the risk of virus transmission and infection due to hand contact.

In addition, since the thickness of both left and right ends of the upper adhesion portion 112 is formed to be the same as the thickness of both left and right ends of the wrinkle portion 111 by thermal fusion or sewing, both left and right ends of the mask body 110 including the upper adhesion portion 112 are formed. In addition, it can be closely adhered to the wearer's side cheek without lifting, so that the blocking effect of splashes and the like can be enhanced.

Meanwhile, according to another embodiment of the mask 100' according to the present invention, the lanyard 120 can be coupled to the mask body 110 so that the length can be adjusted.

That is, as shown in (a) of FIG. 5, when the hook string 120' is coupled to the top of the mask body 110, the end of the hook string 120' is connected to the mask body 110 and the upper part. In a state in which the contact part 112 is located in the gap between the firstly folded first folded part 112a, the mask body 110 and the upper contact part corresponding to the upper and lower sides of the lanyard 120'. (112) are joined by thermal fusion or sewing (122a, 122b).

Next, as shown in (b) and (c) of FIG. 5, the end of the lanyard 120' is exposed to the side of the mask body 110 again while wrapping either the heat-sealed or sewn part. After that, the mask body 110 and the upper contact part 112 corresponding to the upper or lower side of the exposed hanging string 120 are coupled by heat fusion or sewing 122c, so that the hanging string 120 is attached to the mask body. (110).

With the structure as described above, in the process of pulling the end exposed to the outside of the lanyard 120 or the other side connected to the lower end of the mask body 110, the length of the end exposed to the outside of the lanyard 120 is adjusted. The length of the lanyard 120 can be adjusted.

At this time, although not shown, in a state in which the end of the lanyard 120 is folded to a certain length, the mask body 110 and the upper contact part 112 are placed in the gap between the first folded part 112a, and then The mask body 110 and the upper contact portion 112 corresponding to the upper, lower, and central parts of the entire hanging strap 120 in a folded state may be thermally fused or sewn together to combine the hanging strap 120. Of course, the heat-sealed or sewn position is made the same as in the above-described embodiments 122a, 122b, and 122c.

In addition, the lanyard 120 has an end exposed to the outside of the mask body 110 enters the gap between the mask body 110 and the primary folded portion 112a where the upper contact portion 112 is primarily folded. A knot may be formed at the exposed end of the lanyard 120 so as not to go, or a separate stopper may be further provided.

Therefore, according to the mask 100 according to the present invention, the upper end in contact with the bridge of the nose is folded in two stages, so that it adheres to the wearer's face such as the bridge of the nose, cheeks, and chin without a nose wire to improve airtightness. , Since it is manufactured without a nose wire, there is no cost for purchasing a nose wire, and there is no nose wire insertion process, so the manufacturing process is reduced and production cost can be reduced. It is possible to have various advantages such as reducing environmental pollution.

Although preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to those within the scope substantially equivalent to the embodiments of the present invention, and the spirit of the present invention Various modifications and implementations are possible by those skilled in the art to which the present invention pertains within the scope that does not deviate from the above.
