Also, reference numeral A in the drawing indicates an upper flip (A) among the upper and lower flips provided in the mask 200, and the letter A is used to easily identify where the upper flip (A) corresponds in the drawing. indicated using it.

The mask 200 according to the present invention has a configuration in which the mask frame 100 of the present invention is integrally attached to its inner surface. If necessary, the mask 200 according to the present invention may further include an anti-fog film 110 as a member capable of preventing fogging of the glasses when the glasses are worn.

First, the mask frame 100 of the present invention will be described in detail with reference to the drawings. In the present invention, the mask frame 100 is made of a plate material made of a material such as paper having a predetermined strength, and a fold line that can be folded or a perforated line that is cut is formed on the plate material by compression press, etc., and is easy to fold and assemble. to have a three-dimensional shape. As mentioned above, the mask frame 100 of the present invention is attached to the inner surface of the mask 200. For example, both sides of a plate material constituting the mask frame 100 are coated with polyethylene or the like, and the coated surface is ultrasonic- It is installed by integrally adhering to the inner surface of the mask by a method such as thermal evaporation. Therefore, when the wearer performs a simple operation of fastening the upper and lower frames and folding along the fold line formed on the mask frame 100 while wearing the mask 200 on the face, the mask 200 with the mask frame 100 ) is made into a three-dimensional structure, that is, a three-dimensional form. In this state, when the mask is worn on the face, an air zone is formed inside the mask, and the air flow between the nose and mouth is separated to reduce bad breath, and the air pressure generated by exhalation is distributed to both sides in the horizontal direction to discharge air. By making this smoothly, the wearer can feel more comfortable, and fogging can be effectively suppressed or blocked.

1 shows a schematic front view showing the mask frame 100 of the present invention. As mentioned above, in a state before use, the mask frame 100 becomes a flat member, so FIG. 1 is also shown in a flat state. As illustrated in the drawing, the mask frame 100 of the present invention has a configuration including an upper frame 1 and a lower frame 2.

The upper frame 1 is made of a plate member elongated in the horizontal direction, and has an oval upper half shape in which a central portion rises upward in the vertical direction as a whole. Two horizontal fold lines are formed in the upper frame 1, and the two horizontal fold lines, that is, the first horizontal fold line 11 and the second horizontal fold line 12 are spaced apart in the vertical direction and in the horizontal direction. is elongated to In the interval between the first horizontal fold line 11 and the second horizontal fold line 12, a plurality of upper air intake/discharge ports 16 are formed at intervals in the horizontal direction. Above the first horizontal fold line 11, a protective makeup film 10 is provided, and below the second horizontal fold line 12, exhalation air flow guide wings 13 and a nose-mouth shield 14 is provided. Side air outlets 15 are formed at both ends of the upper frame 1 in the horizontal direction. In addition, the upper frame 1 is formed with a fitting hole 19 into which a coupling portion 29 of the lower frame 2 to be described later is inserted.

As mentioned above, the makeup protective film 10 is located above the first horizontal fold line 11. That is, the makeup protective film 10 is provided integrally with the upper frame 1 so that it can be folded along the first horizontal folding line 11 at the upper edge of the upper frame 1 by forming a pair of two. The pair of makeup protective films 10 are disposed in a mirror-symmetric relationship with each other in the width direction with the center of the upper frame 1 as the center.

When the mask frame is worn by folding along the first horizontal fold line 11, the lower part of the first horizontal fold line 11 protrudes outward and the makeup protective film 10 is laid down so that the makeup protective film 10 is worn on the wearer's face. It is located above the cheekbone area of the face. In this configuration, the inner surface of the makeup protective film 10 comes into direct contact with the wearer's facial skin. At this time, the inner surface of the makeup protective film 10 in direct contact with the wearer's facial skin is coated to prevent the facial makeup from being erased. It is formed into a smooth surface made of a material that does not erase makeup or is difficult to erase, such as polyethylene, by various surface treatment methods such as compression and compression. The makeup protective film 10 preferably has a size that can sufficiently cover the wearer's facial cheekbone area. When a conventional mask is worn, the cheekbone area of the wearer's face comes into contact with the inner surface of the mask, which causes the wearer's facial makeup to be erased and the inner surface of the mask to be contaminated. However, in the present invention, the makeup protective film 10 exists between the inner surface of the mask 200 and the facial skin in the area of the cheekbones of the wearer's face, so that the wearer's face does not directly touch the inner surface of the mask, thereby preventing makeup from being removed. It is possible to effectively prevent the development and thus the contamination of the inner surface of the mask.

The nose-mouth blocking film 14 is positioned below the second horizontal fold line 12 and is positioned at the center of the mask frame 100 in the horizontal direction. Therefore, when the mask frame 100 is worn, the nose-mouth shield 14 covers the lower part of the nose and the philtrum of the wearer, and accordingly, exhalation through the nose (“exhalation of the nose”) and exhalation through the mouth (“mouth of the mouth”) Exhaled breath") has a very useful effect of separating so that they do not mix with each other. That is, since the air flow due to exhalation of the mouth is blocked by the nose-mouth barrier 14, it does not directly flow toward the upper nose. Therefore, the air flow caused by exhalation of the mouth is discharged out through the mask in the outer direction or is discharged through both sides of the mask in the horizontal direction, thereby effectively preventing bad breath from remaining inside the mask.

The exhalation air flow guide vanes 13 are also positioned in a continuous form with the nose-mouth shield 14 below the second horizontal fold line 12, and on both sides of the nose-mouth shield 14 in the horizontal direction, 2 Dogs are provided in pairs. A pair of exhalation air flow guide blades 13 are positioned in a mirror-symmetrical relationship in the horizontal direction with the nose-mouth shield 14 as the center. The exhalation air flow guide vane 13 is present in a state connected to the nose-mouth shield 14, but between the exhalation air flow guide vane 13 and the nose-mouth shield 14, the intermediate fold line 130 formed inclined in the vertical direction ) exists. The middle fold line 130 may be formed and provided in plurality. Therefore, when the middle fold line 13 is folded while lifting the nose-mouth shield 14, the nose-mouth shield 14 is placed on the nose of the wearer and the exhalation air flow guide vanes 13 are positioned below it, that is, the wearer located closer to the face of the In this way, since the nose-mouth blocking film 14 and the exhalation air flow guide vanes 13 are positioned at different heights from the wearer's face to the outer surface, it is possible to effectively block the inflow of air caused by exhalation of the mouth into the nose. In particular, the exhalation air flow guide vanes 13 do not flow the flow of air discharge upward or downward in the vertical direction for exhalation of the mouth or nose, but directly guide the flow in the outer direction so that it passes through the mask and is discharged outside. It is made or distributed on both sides in the horizontal direction to be discharged through the side air outlet 15 of the upper frame 1. In this way, the exhalation air flow guide vanes 13 connected to the nose-mouth blocking film 14 block the wearer's mouth and nose widely on both sides in the horizontal direction as a boundary, thereby exhibiting the function of separating the air zone. Through the separation, the effect of preventing bad breath is increased, and the inflow of moisture to the upper part is prevented, thereby exhibiting an effect of preventing fogging.

The upper air intake-outlet 16 is formed in the gap between the first horizontal fold line 11 and the second horizontal fold line 12, and the air flow directly passes through the mask frame 100 and the mask 200. It has the function of allowing it to pass through. At the position where the nose-mouth blocking film 13 and the fogging blocking film 110 exist, the flow of air by the exhalation of the nose to the outer surface is blocked, and accordingly, the air by the exhalation of the nose is supplied to the upper frame 1 However, in the present invention, since the upper air intake-outlet 16 is formed above the nose-mouth blocking film 13 and the fog blocking film 4 as above, Air is discharged out through the upper air intake-exhaust port 16 directly past the mask, thereby effectively preventing an excessive increase in air pressure inside the upper frame 1.

The air pressure inside the mask may also instantaneously increase due to exhalation of the mouth. In this case, the air flow due to the exhalation of the mouth may partially flow into the upper frame 1. However, in the present invention, the air flowing from the upper frame 1 due to the exhalation of the mouth is immediately discharged out through the upper air intake-discharge port 16 through the mask, and therefore, from the inside of the upper frame 1 due to the exhalation of the mouth It is possible to effectively prevent an excessive increase in air pressure.

On the other hand, even in the case of nose inhalation and mouth inhalation, external air can directly pass through the mask and flow into the inside of the mask through the upper air intake-outlet 16, and accordingly, inhalation from the nose and inhalation from the mouth inhalation can be performed smoothly.

The side air outlets 15 are formed at both ends of the upper frame 1 in the horizontal direction, and are composed of a plurality of horizontally folded lines or perforated lines, and function to discharge air existing inside the mask to the outside of the mask. Prevent excessive increase in air pressure inside. In particular, since the side air outlet 15 is formed of a folded line or perforated line as described above, when worn on the face, the horizontal end of the mask frame 100 is made into a three-dimensional shape rather than a plane, and this three-dimensional shape is on both sides in the horizontal direction. In this, it exhibits a very useful function as a support for maintaining the shape of the mask frame 100.

Next, the lower frame 2 will be described. The lower frame 2 is also made of a plate member extending in the horizontal direction, and is spaced apart from the upper frame 1 in the vertical direction at the center, but is integral with the upper frame 1 by bridge parts 21 at both ends in the horizontal direction. is connected to In this way, the upper frame 1 and the lower frame 2 are spaced apart from each other in the vertical direction from the central position of the mask, and accordingly, a large empty space exists in the mask frame 100 where the wearer's mouth is located. will do Therefore, when wearing a mask to which the mask frame 100 is attached, the wearer's mouth feels comfortable, and the wearer's mouth directly faces the inner surface of the mask 200, and the outside air passes through the mask 100. is easily introduced into the inside and the air inside the mask 100 is easily discharged to the outside through the mask 100.

The bridging portion 21 is a portion that integrally connects the upper and lower frames 1 and 2, and the bridging portion 21 is cut so that a coupling portion 22 protruding upward in a bar shape is formed in the bridging portion 21. A perforated line 210 is formed. That is, by the perforated line 210 formed in the bridge portion 21, the convex bar-shaped coupling portion 29 is formed integrally with the lower frame 2 at the upper edge of the lower frame 2. A protrusion is formed at the edge of the coupling part 29 . At both ends of the upper frame 1 in the horizontal direction, fitting holes 19 into which the coupling part 29 is to be inserted are formed at positions above the upper end of the coupling part 29 in the vertical direction. With the mask frame 100 of the present invention attached to the inner surface of the mask 200, the wearer performs a folding operation along the folding line formed on the mask frame 100, and combines as shown in FIGS. 4 and 5 When the portion 29 is inserted into the fitting hole 19, the upper frame 1 and the lower frame 2, which exist on the same plane, have an angle with each other and become convex in the direction of the outer surface, and the mask frame 100 and the mask (200) has a three-dimensional shape that can be worn on the face, that is, a three-dimensional structure. Since a protrusion is formed in the coupling portion 29, in a state where the coupling portion 29 is inserted into the fitting hole 19, the projection is caught in the fitting hole 19, and the coupling portion 29 is removed from the fitting hole 19. It becomes a state that does not easily fall out, and accordingly, the mask frame 100 and the mask 200 can stably maintain the three-dimensional shape convex in the outer direction. When the coupling part 29 is more deeply inserted into the fitting hole 19 and maintained therein, the three-dimensional shape of the mask frame 100 and the mask 200 can be further maximized. That is, the mask frame 100 and the mask 200 have a more three-dimensional shape.

In the bridge part 21, a plurality of bridge part fold lines 22 extending in the horizontal direction may be formed side by side at intervals in the vertical direction. When the folding lines 22 of the bridge portion are formed in this way, it is possible to adjust the position of the lower frame 2 and accordingly to adjust the three-dimensional shape of the lower part of the mask 200 . Specifically, when the bridge part 21 is folded along the folding line 22 of the bridge part 21, the vertical length of the bridge part 21 is reduced and the lower frame 2 is further pulled toward the upper frame 1. Therefore, the wearer can bring the lower frame 2 to a comfortable position by adjusting the degree of folding along the fold line 22 of the bridge part. In addition, when the bridge folding line 22 is not folded or the bridge folding line 22 does not exist, the entire lower frame 2 has a soft curved shape, but the bridge along the bridge folding line 22 When the part 21 is folded, the lower frame 2 protrudes more toward the front, and accordingly, the mask 200 protrudes more to the front from the wearer's chin, so that the mask 200 has a more three-dimensional shape. As this is achieved, the advantage of securing a wider inner space of the mask is demonstrated.

As mentioned above, the mask 200 according to the present invention may further include an anti-fog film 110 as a member capable of preventing fogging of the glasses when wearing the glasses, if necessary. As illustrated in the drawing, the anti-fog film 110 is installed at the upper part in the vertical direction from the center of the mask 200. Specifically, the anti-fog film 110 is located on the upper part of the wearer's nose, but the amount of the wearer in the horizontal direction. It is composed of a member in the form of a band that extends beyond the starting point of the eye and extends at least to a position where the nose pad 310 of the glasses 300 can be stably seated (see FIG. 8).

The anti-fog film 110 is bent to fit the curve of the nose and adheres to the nose. Since the inner surface of the anti-fog film 110 comes into contact with the wearer's nose, that is, the wearer's skin, slipperiness of polyethylene or the like can be maintained as needed to prevent makeup from smearing without irritating the skin. It can be coated with any material. The anti-fog film 110 is bonded to the main body of the mask 200 by means of sewing or ultrasonic-thermal evaporation.

When wearing the mask 110 of the present invention equipped with the anti-fog film 110 having such a configuration, as illustrated in FIG. 8, the nose pads of the glasses are on the outer surface of the anti-fog film 110. While being placed, the anti-fog film 110 is continuously pressed in the direction of the face, thereby maximizing the state in which the anti-fog film 110 adheres to the nose and maintaining the adhesion. As such, in a state in which the anti-fog film 110 is stably adhered to the nose, the air generated inside the mask by exhalation flows along the outer surface of the nose and is not discharged toward the wearer's eyes, that is, in the direction of wearing glasses. As above, since the nose portion is covered with the anti-fogging film 110, the exhalation of the nose and the exhalation of the mouth made inside the mask are not discharged to the upper part of the nose, and as described above, the mask frame 100 of the present invention It is discharged either directly through the 200 or dispersed to both ends in the horizontal direction. Therefore, in the mask 200 of the present invention, it is possible to fundamentally block fogging of glasses. In addition, as described above, in a state where the anti-fog film 110 adheres to the nose and covers the nose, the wearing state of the mask is maintained firmly and stably. Conversely, even if a phenomenon such as being pulled toward the ear occurs, a very useful effect of preventing the mask 200 from being biased or distorted in either horizontal or horizontal direction is exhibited.

As described in detail above, while wearing the mask 200 equipped with the mask frame 100 on the face according to the present invention, the folding operation along the fold line formed on the mask frame 100 and the simple operation of fastening the upper and lower frames When performing, the mask frame 100 together with the mask is also made into a three-dimensional structure according to the shape of the mask, so that an air zone is formed inside the mask 200, and thus a useful effect of making the wearer's breathing more comfortable is exhibited. .

In particular, in the present invention, the air flow between the nose and the mouth is separated by the nose-mouth shield 14 and the exhalation air flow guide vanes 13 provided in the mask frame 100, and the separated air flow is directed toward the outer surface. It is induced and discharged out through the mask or is distributed to both sides in the horizontal direction and discharged through the side air outlets 15, thereby reducing bad breath and preventing the air pressure inside the mask from being excessive, so the wearer is more comfortable can feel

In addition, the present invention may further include an anti-fog film 110. As the anti-fog film 110 adheres to the nose of the wearer, exhalation of the nose and exhalation of the mouth made inside the mask are discharged upward of the nose. It is blocked or suppressed, and accordingly, even if the glasses are worn, the effect of effectively preventing the occurrence of fogging on the glasses is exhibited, and furthermore, as the anti-fog film 110 adheres to the nose, the mask is biased or It is possible to maintain a comfortable wearing state firmly and stably without twisting, so that a very useful effect of feeling a very good wearing feeling is exhibited.
