A foldable mask frame with a flat structure for improving breathing and preventing bad breath based on an anti-fog structure and a mask equipped with the same {Mask frame for improving breathing and blocking bad breath and fogging, and Mask having such Mask frame}

The present invention relates to a mask (mark) worn on the face for quarantine or dust blocking, and a mask frame (Mask frame) placed on the inner surface of such a mask. Specifically, the present invention relates to a mask frame made of a plate on the inner surface of the mask. However, the mask frame is equipped with a nose-mouth barrier and exhalation airflow guide wings, and when not in use, it exists in a flat form. When the mask frame is simply folded for use, the mask is combined with the mask frame. It is made in a three-dimensional shape, so an air zone that allows comfortable breathing is formed inside the mask. By blocking the air flow between the nose and mouth, bad breath can be reduced, and the air pressure from exhalation is distributed to the left and right to prevent air discharge. By making it smooth, you can reduce the fogging phenomenon that causes your glasses to become cloudy due to your breath and improve the ease of breathing. Furthermore, if necessary, by adding an anti-fog film, you can further strengthen the adhesion at the nose area to prevent your glasses from fogging. This can occur, and furthermore, it relates to a "flat structure foldable mask frame for improving breathing and preventing bad breath based on an anti-fog structure and a mask equipped therewith" that can solve problems such as the mask falling off and face makeup being removed. .

In the case of a mask according to the prior art, when moisture reaches a certain level in the air zone area of the mask while the user is wearing the mask, the air discharge effect to the front of the mask decreases and bad breath occurs. do. In addition, due to the reduced air discharge effect from the front of the mask, exhaled breath is discharged from the part of the mask that is in contact with the nose area under the eyes, which has the weakest contact with the face. This causes significant discomfort due to fogging of the glasses in the case of glasses wearers. There is a problem that makes you feel bad.

To solve this problem, various proposals have been made through Korean Patent No. 10-2013953, etc. However, in the case of these existing proposals, the facial sealing effect is reduced due to facial movement or air is discharged to unintended locations. There are limitations in that the anti-fogging effect is not satisfactory due to phenomena such as

Republic of Korea Patent Publication No. 10-2013953 (announced on August 23, 2019).

The present invention was developed to overcome the limitations of the prior art as described above. It reduces fogging when wearing a mask on the face, makes breathing easier by immediately dispersing the amount of exhaled air, and makes it easier to breathe through the mouth.

FIGS. 2, 4, and 8 are views from the outer surface to the inner surface, and FIGS. 3, 5, and 7 are views from the inner surface to the outer surface. In FIGS. 2 and 3 , arrows indicate the direction in which the mask frame 100 is coupled to the mask 200. In the drawing, the symbol A indicates the upper flip (A) among the upper and lower flips provided in the mask 200, and the alphabet A is used to easily determine where the upper flip (A) corresponds in the drawing. It is indicated using.

The mask 200 according to the present invention has a structure 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 be further provided with a fogging blocking film 110 as a member that can prevent the phenomenon of fogging the glasses when wearing them.

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 made of a material such as paper with a predetermined strength. The plate is formed with a fold line or a cut line that can be folded by a compression press, etc., and is used for folding and assembly. It has a three-dimensional shape. As mentioned earlier, the mask frame 100 of the present invention is attached and installed on the inner surface of the mask 200. For example, both sides of the plate forming the mask frame 100 are coated with polyethylene, etc., and the coated side is ultrasonic- It is installed by integrally adhering it to the inner surface of the mask using a method such as thermal evaporation. Therefore, when the wearer performs the simple task of folding the mask 200 along the fold line formed on the mask frame 100 and fastening the upper and lower frames while wearing the mask 200 on the face, the mask 200 along with the mask frame 100 ) is created in a three-dimensional structure, that is, in a three-dimensional form. In this condition, when the mask is worn on the face, an air zone is formed inside the mask, the air flow between the nose and mouth is separated to reduce bad breath, and the air pressure from exhalation is distributed to both sides in the horizontal direction to exhaust air. By making this happen smoothly, the wearer can feel more comfortable, and fogging can also be effectively suppressed or blocked.

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

The upper frame 1 is made of a plate member extending horizontally, and has an oval upper half shape with the central part rising vertically upward. Two horizontal fold lines are formed within the upper frame (1). 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 are formed in the horizontal direction. It is extended for a long time. In the gap 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 horizontal intervals. A cosmetic protective film 10 is provided above the first horizontal fold line 11, and an exhalation air flow guide wing 13 and a nose-mouth barrier 14 are provided below the second horizontal fold line 12. This is provided. Side air outlets 15 are formed at both horizontal ends of the upper frame 1. In addition, the upper frame 1 is formed with a fitting hole 19 into which the coupling portion 29 of the lower frame 2, which will be described later, is inserted.

As mentioned above, the cosmetic protective film 10 is located above the first horizontal fold line 11. That is, two cosmetic protective films 10 are formed as a pair and are provided integrally with the upper frame 1 so that they can be folded along the first horizontal fold line 11 at the upper edge of the upper frame 1. This pair of cosmetic protective films 10 are arranged in mirror symmetry with each other in the width direction with the exact 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 in the outer direction and the makeup protective film 10 is laid down, so that the makeup protective film 10 is exposed to the wearer's skin. It is located above the cheekbone area of the face. In this configuration, the inner surface of the makeup protective film 10 is in direct contact with the wearer's facial skin. At this time, the inner surface of the makeup protective film 10 that directly contacts the wearer's facial skin is coated to prevent facial makeup from being erased. It is formed into a smooth surface made of a material that does not remove makeup or is difficult to remove, such as polyethylene, through various surface treatment methods such as pressure. The makeup protective film 10 preferably has a size that sufficiently covers the cheekbone area of the wearer's face. 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 removed and the inner surface of the mask to become contaminated. However, in the present invention, a makeup protective film 10 is present between the inner surface of the mask 200 and the facial skin in the cheekbone area of the wearer's face, so that the wearer's face does not directly contact the inner surface of the mask, and thus the makeup is not removed. It is possible to effectively prevent the phenomenon and the resulting contamination of the inner surface of the mask.

The nose-mouth blocking film 14 is located below the second horizontal fold line 12 and is located at the exact center of the mask frame 100 in the horizontal direction. Therefore, when the mask frame 100 is worn, the nose-mouth barrier 14 covers the wearer's lower nose and philtrum area, and accordingly, exhalation through the nose ("nasal exhalation") and exhalation through the mouth ("mouth exhalation") This has a very useful effect of separating the exhaled breath so that it does not mix with each other. In other words, the air flow caused by exhalation from the mouth is blocked by the nose-mouth barrier 14, so it does not flow directly toward the upper nose. Therefore, the air flow caused by exhalation from the mouth passes through the mask in the outer direction and is discharged outward or 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 wings 13 are also located in a continuous form with the nose-mouth barrier 14 below the second horizontal fold line 12, and are positioned 2 on both sides of the nose-mouth barrier 14 in the horizontal direction. Dogs are provided in pairs. A pair of expiratory airflow guide wings (13) are positioned in a mirror-symmetrical relationship in the horizontal direction with the nose-mouth barrier (14) as the center. The exhalation airflow guide wing 13 exists in a state connected to the nose-mouth barrier 14, but between the exhalation airflow guide wing 13 and the nose-mouth barrier 14, an intermediate fold line 130 is formed inclined in the vertical direction. ) exists. The middle fold line 130 may be formed in plural numbers. Therefore, when the middle fold line 13 is folded while lifting the nose-mouth barrier 14, the nose-mouth barrier 14 is placed on the wearer's nose and the exhalation air flow guide wings 13 are positioned below it, that is, when the wearer It is located closer to the face of the. In this way, since the nose-mouth barrier 14 and the expiratory air flow guide wings 13 are positioned at different heights from the wearer's face to the outer surface, it is possible to effectively block air from exhaling from the mouth from entering the nose. In particular, the exhalation air flow guide wings 13 do not allow the flow of air discharge to flow vertically upward or downward with respect to exhalation from the mouth or nose, but directly guide the flow in the direction of the outer surface so that it passes through the mask and is discharged outside. 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 wings 13 connected to the nose-mouth barrier 14 exert the function of separating the air zone by blocking the wearer's mouth and nose broadly on both sides in the horizontal direction, and this air zone Separation increases the effect of preventing bad breath and prevents fogging by preventing moisture from entering the upper part.

The upper air intake-discharge port 16 is formed in the gap between the first horizontal fold line 11 and the second horizontal fold line 12, and allows the air flow to directly connect the mask frame 100 and the mask 200. It functions to allow water to pass through and flow. At the position where the nose-mouth barrier 13 and the fogging barrier 110 are present, air due to exhalation of the nose is blocked from flowing toward the outer surface, and accordingly, air due to exhalation of the nose flows into the upper frame (1). ) However, in the present invention, the upper air intake-outlet 16 is formed above the nose-mouth barrier 13 and the fogging barrier 4 as above, so that the The air passes through the mask directly through the upper air intake-discharge port 16 and is discharged outward, thereby effectively preventing excessive increase in air pressure inside the upper frame 1.

The air pressure inside the mask may momentarily increase due to exhalation from the mouth. In this case, the air flow due to exhalation from the mouth may partially flow into the interior of the upper frame (1). However, in the present invention, the air flowing into the upper frame (1) due to exhalation of the mouth is immediately discharged outside the mask through the upper air intake-discharge port (16), and therefore, the air inside the upper frame (1) due to exhalation of the mouth is discharged outward. Excessive increase in air pressure can be effectively prevented.

Meanwhile, in the case of inhalation from the nose and inhalation from the mouth, external air can pass directly through the mask through the upper air intake-outlet 16 and flow into the inside of the mask, and accordingly, inhalation from the nose and mouth Inhalation can occur smoothly.

The side air outlet 15 is formed at both horizontal ends of the upper frame 1 and is made up of a plurality of horizontal folds or perforations, and functions to discharge the air present inside the mask to the outside. Prevents internal air pressure from increasing excessively. In particular, since the side air outlet 15 is made of a fold line or a cut line as shown above, when worn on the face, the horizontal end of the mask frame 100 is made into a three-dimensional shape rather than a flat surface, and this three-dimensional shape is formed on both sides in the horizontal direction. It exerts a very useful function as a support that maintains 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 long in the horizontal direction, and is vertically spaced apart from the upper frame (1) in the central part, but is integrated with the upper frame (1) by bridge parts 21 at both ends in the horizontal direction. It is connected to . In this way, the upper frame 1 and the lower frame 2 are positioned vertically apart from each other at the center position of the mask, and accordingly, there is a large empty space in the mask frame 100 where the wearer's mouth is located. I do it. Therefore, when wearing a mask with the mask frame 100 attached, the wearer feels comfortable in the mouth area, and the wearer's mouth area directly faces the inner surface of the mask 200, allowing external air to pass through the mask 100. The air is easily introduced inside, and the air inside the mask 100 is easily discharged to the outside through the mask 100.

The crosslinking portion 21 is a part that integrally connects the upper and lower frames 1 and 2. The crosslinking portion 21 is cut so that a coupling portion 22 protruding upward in a bar shape is formed in the crosslinking portion 21. A perforation line 210 is formed. That is, the convex rod-shaped coupling portion 29 is formed on the upper edge of the lower frame 2 by being integrated with the lower frame 2 by the perforation line 210 formed on the crosslinking portion 21. A protrusion is formed on the edge of the coupling portion 29. At both horizontal ends of the upper frame 1, fitting holes 19 into which the engaging portion 29 is inserted are formed at positions vertically above the upper end of the engaging portion 29. 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 fold lines formed on the mask frame 100 and combines them as shown in Figures 4 and 5. When the part 29 is inserted into the fitting hole 19, the upper frame 1 and the lower frame 2, which were on the same plane, have an angle to each other and become convex in the outer surface direction, thereby forming 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 the engaging portion 29 is formed with a protrusion, when the engaging portion 29 is inserted into the fitting hole 19, the protrusion is caught in the fitting hole 19 and the engaging portion 29 is inserted into the fitting hole 19. It is in a state in which it does not fall off easily, and as a result, the mask frame 100 and the mask 200 can stably maintain a three-dimensional shape that is convex in the outer direction. By inserting the coupling portion 29 deeper into the fitting hole 19 and maintaining that state, the three-dimensional shape of the mask frame 100 and the mask 200 can be further maximized. In other words, the mask frame 100 and the mask 200 have a more three-dimensional shape.

In the crosslinking portion 21, a plurality of crosslinking portion fold lines 22 extending in the horizontal direction may be formed side by side at intervals in the vertical direction. By forming the crosslink fold line 22 in this way, it is possible to adjust the position of the lower frame 2 and the three-dimensional shape of the lower part of the mask 200 accordingly. Specifically, when the cross-linked portion 21 is folded along the cross-linked portion fold line 22, the vertical length of the cross-linked portion 21 is reduced and the lower frame 2 is further pulled toward the upper frame 1. Accordingly, the wearer can adjust the degree of folding along the crosslink fold line 22 to place the lower frame 2 in a comfortable position. In addition, when the cross-link fold line 22 is not folded or the cross-link fold line 22 does not exist, the entire lower frame 2 has a smoothly curved shape, but cross-linking occurs along the cross-link fold line 22. When the portion 21 is folded, the lower frame 2 protrudes more toward the front, and as a result, the mask 200 protrudes more toward the front from the wearer's chin, giving the mask 200 a more three-dimensional shape. This has the advantage of securing a wider space inside the mask.

As mentioned above, the mask 200 according to the present invention may, if necessary, be further provided with a fogging blocking film 110 as a member that can prevent the phenomenon of fogging the glasses when wearing them. As illustrated in the drawing, the fogging barrier 110 is installed at the vertical upper part in the center of the mask 200. Specifically, the fogging barrier 110 is located on the upper part of the wearer's nose and is oriented horizontally across the wearer's nose. It is made of a band-shaped member that extends further past the starting point of the eyes to at least 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 comes in close contact with the nose. The outer surface of the anti-fog film 110 is coated with a silicone or rubber material to prevent the glasses from slipping off. Since the inner surface of the fogging barrier 110 is in contact with the wearer's nose, that is, the wearer's skin, slipperiness such as polyethylene can be maintained as necessary in order to prevent makeup from smearing without irritating the skin. Can be coated with any material. The fogging barrier 110 is provided by being bonded to the main body of the mask 200 by 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, the nose pad of the glasses is on the outer surface of the anti-fog film 110, as illustrated in FIG. 8. As it is placed, the fogging shield 110 is continuously pressed in the direction of the face, thereby maximizing the state in which the fogging shield 110 is in close contact with the nose and maintaining adhesion. In this way, in a state where the anti-fog film 110 is in stable close contact with the nose, the exhaled air generated inside the mask flows along the outer surface of the nose and is not discharged toward the wearer's eyes, that is, in the direction in which the glasses are worn. As described above, since the nose area 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 above the nose, and as described above, the mask can be used through the mask frame 100 of the present invention. It passes directly through (200) or is distributed and discharged to both ends in the horizontal direction. Therefore, the mask 200 of the present invention can fundamentally prevent fogging of glasses. In addition, as shown above, when the anti-fogging film 110 is in close contact with the nose and covers the nose, the wearing condition of the mask is maintained firmly and stably, and the tension acting on the earring strings of the mask changes accordingly, causing the earring strings to become loose or loose. Or, conversely, even if a phenomenon such as being pulled further toward the ear occurs, the mask 200 is not biased or distorted in either the horizontal or horizontal direction, which has a very useful effect.

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

In particular, in the present invention, the air flow between the nose and mouth is separated by the nose-mouth barrier 14 and the exhalation air flow guide wings 13 provided on the mask frame 100, and the separated air flow is directed to the outer surface. It is guided and discharged outward through the mask, or distributed to both sides in the horizontal direction and discharged through the side air outlet (15), thereby reducing bad breath and preventing excessive air pressure inside the mask, making the wearer more comfortable. You can feel it.

In addition, the present invention may be further provided with a fogging shield 110. The fogging shield 110 is in close contact with the wearer's nose, so that the exhalation from the nose and the exhalation from the mouth made inside the mask are discharged upward from the nose. is blocked or suppressed, and this effectively prevents fogging of glasses even when wearing glasses. Furthermore, the fog blocking film 110 adheres closely to the nose, so that the mask is biased or It has the very useful effect of being able to maintain a comfortable wearing condition firmly and stably without being distorted, thereby providing a very good wearing feeling.
