Description

Transparent plastic face mask having an integral cover plate {Mask for wearing on the face based on transparent plastic with an integral cover plate}

The present invention relates to a face mask. The face mask according to the present invention forms the mask body and the integrated cover plate with a transparent plastic material in one process, and forms the double cover part by the integrated cover plate from the inside and outside of the opening, thereby making it easy to breathe and blocking the splash An object of the present invention is to provide a transparent plastic face mask having an integrated cover plate that can increase the temperature and reduce the manufacturing process, and is suitable for water play such as a water park.

A conventional mask is a concept that blocks externally contaminated infectious materials through a filter. Recently, as awareness of hygiene and environmental conditions is heightened, and environmental pollution such as fine dust or yellow sand has become serious, wearing a face mask is becoming a reality.

In recent years, in particular, the use of face masks has become routine for an infectious disease called COVID 19, and while social distancing is recommended, it is mandatory to wear a face mask when using public transportation or in a closed space. In order to prevent and spread these infectious diseases, the most important factor is to prevent discharge or inhalation of droplets or aerosols.

As a conventional face mask, there is Korean Patent Application Laid-Open No. 10-2012-0055584, "Mask" (published on May 31, 2012) that can exhibit antibacterial or antiviral action.

The face mask as in the prior art is usually marked with performance like KF80 to KF95 depending on the performance of the filter, and the better the performance, the less breathable, so breathing may not be smooth. In addition, as using a filter sheet containing fibers that improve antibacterial performance in a nonwoven fabric, it is difficult to reuse because it is impossible to wash with water, and there are disadvantages in that the mask is wet and difficult to wear when playing in water such as a water park or a beach. In addition, since it is made of an opaque material, the shape of the wearer's mouth cannot be known from the outside, so communication with the hearing impaired is difficult.

On the other hand, face masks made of materials that do not get wet (eg, plastic materials) are also known. For example, the face masks worn by cooks simply prevent splashing downwards and keep the mouth open upwards. It's like a mask. Therefore, it is difficult to prevent the spread of droplets in such a muzzle mask.

In addition, as a face mask made of a transparent plastic material, Korean Patent Application Laid-Open No. 10-2020-0079480 (published on July 03, 2020) 'face mask having a cotton plastic piece' has been proposed. Such a face mask made of a transparent plastic material has an advantage in that the shape of the mouth can be seen from the outside. However, since the plastic material does not pass air, vents for intake and exhaust must be provided. The conventional face mask having a transparent plastic piece is configured to be worn with the back and side surfaces spaced apart from the face so that air intake and exhaust are made. This is an open state in which both sides of the face and the back of some sections are open, and it is difficult to block the aerosolized and diffused droplets generated from the nose and mouth.

On the other hand, in general, a face mask made of a transparent plastic material is usually configured to have a structure in which the intake and exhaust filter can be detached from the mask body for air intake and exhaust. In order to attach and detach the intake/exhaust filter box, it is necessary to provide a detachable structure and an intake/exhaust filter box, so the manufacturing cost increases a lot, the structure becomes complicated, and the weight increases when worn, which causes a lot of inconvenience to wear for a long time. In addition, it may not be comfortable to breathe because the intake and exhaust must pass through the filter box.

In addition, as the structure of attaching and detaching the filter box, if the filter box itself is wet with water, the difficulty of intake and exhaust increases as the internal filter gets wet, and it is difficult to use it for swimming because the filter performance cannot be exhibited.

In describing the present invention, in order to facilitate the overall understanding, the same reference numerals are used for the same components in the drawings, and duplicate descriptions of the same components are omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the separation state of the cover and the configuration of the drain hole of the face mask according to the first embodiment of the present invention, Figure 2 is a view showing the coupling state of the cover of the face mask according to the first embodiment of the present invention. As shown in FIGS. 1 and 2 , the face mask according to the present invention is largely configured to include a mask body 10 , and an air intake/exhaust unit including an opening 20 and a cover 30 .

The mask body 10 is made of a transparent plastic material so that it can be worn on the face to cover the nose and mouth. The mask body 10 may be made of a flexible transparent plastic material, for example, a transparent plastic such as PP or PET.

The air intake/exhaust unit includes an opening 20 formed in the mask body 10 to be an air entry/exit passage for breathing, and the mask body 10 so that the upper portion of the opening 20 is covered in a round shape and left and right sides are opened. It includes a cover 30 installed on the.

The air intake and exhaust unit is installed on the front side of the mask body 10, for example, installed at a position corresponding to the mouth. The present invention is not limited thereto, and may be formed on both sides of the mask body 10 , that is, at positions corresponding to both cheeks, or may be formed on the front side and three side surfaces. In the case of forming a plurality of air intake and exhaust units in this way, the size of the opening is different depending on the position where it is formed, a filter is included, or the distance between the cover and the opening is different, so that it is convenient to breathe and it is configured to block the droplets.

The method of manufacturing the face mask of the present invention as described above is a face mask manufacturing method configured by forming an opening in the mask body and combining the covers spaced apart by forming an arc with respect to the opening, comprising a sheet of material constituting the mask body forming the mask body by a vacuum forming process; an opening forming step of perforating an opening in the mask body and forming cutouts at upper and lower sides of the opening; A cover having a length longer than the interval between the upper and lower cutouts and having a width wider than the width of the opening, and a cover having a slanting portion extending from both ends of the cover portion to forcibly tilt the upper and lower cutouts forming a; and a post-processing step of assembling the cover portion spaced apart from the opening in an arc shape by coupling the fitting portions at both ends of the cover by force fitting to the upper and lower cutouts.

The mask body 10 has a body extending from the lower edge open to be in close contact with the wearer's nose, cheeks, and chin so as to be narrowed upwards, so that the upper surface forms a flat front part 11 to form the wearer's nose It is a configuration that forms an internal space so that the mouth and the mouth do not touch. That is, it has a cap type or cup type configuration.

The mask body 10 is provided with a rib portion 12 bent outwardly on the lower edge of the mask body so that soft and close contact with the wearer's face is possible. In addition, the coupling ring part 13 is formed on both sides of the mask body 10 to be symmetrical with each other to couple the mask wearing line.

The coupling ring portion 13, two ring holes spaced apart from each other by a predetermined distance are formed in pairs on both sides of the main body, respectively, by inserting a mask wearing line into the two ring holes and adjusting the length to hang it on the ear. It may include a length adjusting means for adjusting the length so that the Since the length adjusting means is generally known, a description thereof will be omitted.

In addition, the wearing line is fixed to the coupling ring part 13 and a rubber band or a wearing line that can be hung on the ear, a rubber band having both ends fixed to the string or coupling ring part 13 and made to wear a mask by turning it behind the head. , may be composed of a string, a wear line, and the like. Since the mask wearing line is a general configuration, a detailed drawing or description thereof will be omitted.

The air intake and exhaust portion, the lower portion of the front portion 11 of the mask body 10 is formed with an opening 20 of a size that allows the circulation of air so that breathing can be comfortable. The size of the opening 20 may be formed differently according to the size of the mask for adults, children, large, medium, small, and the like.

In addition, in order to couple the cover 30, cut-out portions 21 are respectively formed at the upper and lower sides of the opening 20 in the longitudinal direction. The cut-out portion 21 is formed by cutting both ends of the cover 30 so as to be fitted by force fitting.

The cover 30 has a width wider than the left and right widths of the opening 20 and includes a cover part 31 having a length longer than the interval between the upper and lower cutouts 21 by a predetermined length, and the cover part A fitting portion 33 extending to both ends of the upper and lower ends of the cut-out portion 21 and formed at both ends with a left and right width capable of forcibly fitting into the cut-out portion 21, and between the cover portion 31 and the both ends fitting portion 33, respectively. A locking groove 32 is formed in which a groove is formed from the outside to the inside while leaving a left and right width equal to the length of the cutout 21 .

Such a cover 30 is fitted in the cut-out portion 21 by force-fitting both ends of the fitting portion 33 so that the locking groove 32 matches the cut-out portion 21 . The material of the mask body 10 in which the cutout 21 is formed and the cover 30 is a flexible plastic material and has a thin thickness. Therefore, even if it consists of a width slightly larger than the cut-out length of the cut-out portion 21, it is possible to force-fit.

When the fitting portion 33 of the cover 30 is inserted by making the interval between the left and right locking grooves 32 of the cover 30 equal to the cut-out length of the cut-out portion 21, the cover body portion 31 and Since the width of the fitting portion 33 is formed to be wider than the cutout length of the cutout portion 21 , the cover 30 may be inserted into the cutout portion 21 to be fixed. At this time, since the upper and lower lengths of the cover body 31 are longer than the distance between the upper and lower cutouts 21, the cover body 31 is curved upward and rounded in an arc shape.

As a result, the cover body 31 is spaced apart from the opening 20 in an upward arc shape. Between the cover body 31 and the mask body 10 bent in an arc shape, the left and right sides are opened corresponding to the curved arc.

Accordingly, air may pass through the left and right sides of the cover 30 and be sucked in through the opening 20 . Conversely, the discharged air passes through the opening 20 and may flow to the left and right of the cover 30 while colliding with the cover 30 . Therefore, the liquid or aerosolized droplets discharged from the wearer pass through the opening 30 and collide with the inner surface of the cover 30 and then flow out to the left and right. That is, the face mask according to the present invention is discharged in the lateral direction while blocking the linear scattering of droplets, and the air introduced in the lateral direction is introduced into the mask through the opening 30 . Accordingly, the droplet does not diverge forward, but flows out to the side in a state in which the force to be emitted is lost.

The COVID-19 infectious disease, which has recently made the world a pandemic, is known to spread mainly through droplets, and it is confirmed that wearing a mask that blocks droplets is effective in preventing infectious diseases. Therefore, the face mask of the present invention has a simple structure, not a completely closed type or a filter-passing type, and can prevent droplets from being emitted directly, so it can be used as a face mask suitable for preventing COVID-19 infectious disease.

In addition, since the face mask of the present invention is made of a transparent plastic material, it does not get wet, so you can enjoy playing in the water while wearing the mask at a water park or a beach. Masks including general cotton or filters, when wet with water, it is difficult to breathe through the mask, and also it is difficult to maintain the wearing state because the weight increases when wet with water. In contrast, the transparent plastic face mask of the present invention has the advantage of being able to play in the water while wearing it regardless of getting wet.

On the other hand, if the face mask of the present invention is worn while playing in the water, water can always be introduced into the mask through the air intake and exhaust unit. Most of the water flowing into the mask is discharged through the lower edge of the mask and the gap between the chin and cheek. That is, the mask body 10 cannot be completely sealed to the face, and water may be discharged as the lower edge of the mask is separated from the face contact area according to movement or the like.

However, a large amount of water may be introduced or the water may be stagnant inside the mask depending on the posture.

In the present invention, in order to improve this problem, concave portions are continuously formed at a predetermined interval inside the corner between the front surface 11 and the lower surface of the mask body 10, and drain holes are formed on the lower surface of the mask body between the concave portions. (15) is formed.

When the drain hole 15 is formed as described above, the water introduced into the mask can be easily discharged. At this time, since the drainage hole 15 is formed in the downward direction as a small hole and is formed between the recesses, the droplets are not emitted or introduced in a straight line. That is, even if the drain hole is formed, the droplet blocking effect is not reduced.

In addition, a plurality of concave line portions 16 concave inwardly are further formed on both sides of the mask body 10 as a structure for forming a pattern. This is to improve the aesthetic element by forming a pattern to make it look good.

The face mask according to the present invention is an exemplary view in which one cover is combined in FIGS. 1 and 2, but is not limited thereto, and in the present invention, a double cover may be formed by combining the covers from the inside and outside respectively. .

3 (A) to (C) are diagrams for explaining the configuration of a double cover face mask according to a second embodiment of the present invention.

As shown in (A) and (B) of Figure 3,

A mask body 10 made of a transparent plastic tech material, an opening 20 formed in the mask body 10, and cutouts 21 and 22 formed respectively on upper and lower sides of the opening 20, In the outer and inner portions of the mask body 10, both ends are inserted into the upper and lower cut-outs 21 and 22, respectively, and are spaced apart in a convex arc shape to the outside and the inside to cover the opening 20 from the outside and the inside, respectively. It is configured to include an outer cover 30 and an inner cover 30a that are coupled to each other.

When the cover 30, 30a of the double structure is installed in this way, the opening 20 of the mask body 10 is formed in an arc shape from the inside and outside as shown in FIG. 3 (B), respectively. ) provides a structure in which the Therefore, since the double cover is installed, the air passing through the opening 20 cannot directly pass through, but passes through the open spaces on both sides of the cover and passes through the opening, so that the droplet blocking effect can be significantly increased.

On the other hand, since the upper and lower cutouts 21 and 22, respectively, the outer cover 30 and the indented portions of the inner cover 30a must be fitted from the inside and outside, any one of the inner or outer covers has a sphere near the fitting portion. Since it has to be severely broken, it may not be able to recover its elasticity due to pressing during long-term use.

As a method to solve this, as shown in FIG. 3(C), the upper and lower cutouts 21 and 22 are formed in two stages, respectively. That is, the upper and lower first cut-outs 21 and 22 for coupling the outer cover 30, and the two-stage upper and lower second cut-outs 21a and 22a for coupling the inner cover 30b are further added. forming, the outer cover 30 is defective through the first cutouts 21 and 22, and the inner cover 30a is coupled through the second cutouts 21a and 22a. In this case, when the fittings at both ends of the covers 30 and 30a are inserted into the cutouts, the bending forms a smooth arc, so that the elastic restoring force can be maintained even for long-term use and pressing.

On the other hand, in the configuration of the double cover, a cover plate integrally connected to the mask body is formed without using a separate cover plate, and the double cover can be configured using the cover plate.

(53) to form an integral cover plate 50 divided by each of the engaging grooves (52a, 52b). That is, the mask body and the integrated cover plate are molded in one vacuum forming process.

The integrated cover plate 50 has a first locking groove portion 52a formed between the inner cover portion 54 extending from the edge of the mask body 10 and the outer cover portion 51, and A second locking groove portion 52b is formed between the cover portion 51 and the fitting portion 53 at the tip.

The fitting portion 53 and the second locking groove portion 52b must pass through the upper cut-out 41a, and the first locking groove 52a coincides with the upper cut-out 41a to match the inner cover portion 54. is formed to take The inner cover portion 54 is obliquely coupled between the first cut-out portions 41a at the edge.

The outer cover part 51 passes through the first cut-out part 41a and is caught by the second cut-out part 42b, and the inner cover part 54 is caught by the first cut-out part 41a. At this time, the opening 20 ) should be formed to be wider than the width of the outer cover portion 51, the length of the first cut-out portion 41a is formed to be longer than the length of the second cut-out portion 41b. That is, the length of the first cut-out portion 41a is preferably formed to have the same length as the width of the outer cover portion 51 . Of course, the vertical length of the outer cover part 51 is formed to be longer than the interval between the first cut-out part 41a and the second cut-out part 41b by a predetermined length, so that it is bent in an arc shape so that both sides are open. can be achieved In addition, although not shown in detail in the drawings, as shown in FIG. 1 , a plurality of discharge holes are formed in the jaw line portion to allow the inflow of water to be smoothly discharged.

Since such a structure in which the integrated cover plate 50 is formed can be manufactured integrally when the mask body 10 is vacuum-molded, even the integrated cover plate can be formed in a single process, thereby simplifying the manufacturing process. In addition, since it is integrally connected, even if the end is removed from the cutout during use, it is attached integrally, so there is no fear of loss.

In addition, as shown in FIGS. 4 and 5 , the opening 20 and the region in which the cutout portions 41a and 41b are formed may further include a protrusion 40 protruding to the outside. That is, the protrusion 40 is formed on the front surface 11 of the mask body 10 , and the opening 20 and the upper and lower cutouts 41a and 41b are formed in the protrusion 40 .

The filter unit 61 is preferably formed in a plurality of layers by overlapping a fine dust blocking member such as a nonwoven fabric and a member for an antibacterial filter.

In addition, when the size of the filter is large, as shown in (B) of FIG. 7 , an intermediate frame 65 connecting the edges from the front and back surfaces may be further included in the middle.

As shown in FIG. 8, the filter 6 manufactured as described above has cutouts 42 formed on both sides of the protrusion 40 protruding the region where the opening 20 is formed, and cutouts 42 from the side. ) by inserting the filter (60) through it. Accordingly, the filter 60 may be installed to block the opening 20 , and air may be sucked in or exhausted through the filter through the open portions on both sides of the inner and outer covers.

9 is a view illustrating a state in which a face mask is worn according to an embodiment of the present invention. The transparent plastic face mask according to the present invention is made of a transparent material, and can be worn over the ear by connecting a wearing line to the hook. The transparent face mask has a structure in which the nose and mouth are spaced apart from the mask from the inside while covering the nose and mouth. In addition, an opening is formed in the front part, and an arc-shaped cover is installed in the outer or inner and outer parts of the opening, respectively. Since both sides of the cover are open, air is drawn in or exhausted through the opening. In addition, when the filter is mounted, the filter can be mounted in the opening.

Therefore, if you play in the water with the filter attached, even if the filter gets wet, it does not sag because the filter is mounted on the mask body. Therefore, it can be used as a face mask for swimming even with a filter attached. However, since the amount of respiration can be reduced when the filter is installed, use the filter with the filter removed when playing in the water, and in short-distance conversation outside the water or indoor space, the filter can be installed to increase safety. That is, since the filter can be easily installed or removed, it is possible to easily select whether to install the filter while playing in the water and use it, which can add convenience.
