Description

MASK HAVING A VERTICALLY EXTENDING MAIN PAD AND MANUFACTURING METHOD THEREOF

The present invention relates to a mask, and more particularly, to a mask having a vertical body pad and a method for manufacturing the same.

Respiratory diseases, such as the flu, cold, and COVID-19, are mainly caused by viruses, and are transmitted through contact or droplets. One of the methods to prevent the spread of such a virus is to wear a mask. The mask is in close contact with the wearer's nose and mouth to filter out viruses, fine dust, or yellow dust from the outside, and prevent the wearer's droplets from spreading.

Masks currently on the market are mainly composed of one of three structures. One is a structure in which one partially folded member crosses the user's entire face, and the other is a symmetrical member in the middle. The structure is joined along a line, and the other is a structure in which a member designed to be closely attached to the user's nose bridge and a member designed to be supported under the user's chin are joined to the top and bottom of one member extending long in the horizontal direction.

In all of the above structures, the mask is supported by the tip of the user's nose and both sides of the face. Therefore, it is usually extended longer than this. This means that the mask has to be manufactured in a large area that covers most of the user's face, and thus the material is required over a large area, which means that the manufacturing cost is high.

In the case of a mask including a filter, if the member provided inside the filter is bent, the filter may be damaged, so that the mask member is not bent at a portion other than the junction between each member. However, since the mask of the prior art has a large area, the packaging material for accommodating the mask without bending it also occupies a large area. In the field of mask manufacturing, the cost of the mask itself is not high, so the cost of packaging material can have a significant impact on final price competitiveness.

On the other hand, from the perspective of the user wearing the mask, since the mask runs along a smooth curve from the tip of the user's nose to both sides of the face, the user's nose and mouth come into contact with the inner surface of the mask. Rather, this may result in contamination of the inner surface of the mask by the user's body parts, and when moisture condenses on the inner surface of the mask when the outside temperature is low or the user exercises vigorously, it may cause discomfort to the user in contact with it.

In addition, when the mask covers a significant part of the user's face, there is an inconvenience that it becomes difficult for others to distinguish who the wearer is. Recently, a so-called "lip view" mask has been developed that is configured to show the user's mouth from the outside by attaching a window made of a transparent material to a part of the mask. There is a limit that only the lips (ie, lip) of the window are visible, and as the area occupied by the window increases, the area of the filter that filters outside air decreases.

Accordingly, the present invention has been derived to solve the above-described problems, and an aspect of the present invention is to provide a mask and a method for manufacturing the same, which are manufactured in a small area to reduce manufacturing cost and packaging cost.

Another aspect of the present invention is to provide a mask and a method of manufacturing the same that the mask does not deviate from its original position even when the user wearing the mask moves his/her mouth so that the user can use it comfortably.

Another aspect of the present invention is to provide a mask that a user can comfortably use by minimizing the portion of the mask in contact with the user's nose and mouth and preventing exhaled air containing moisture from being discharged upwards, and a method for manufacturing the same.

The front portion 140 may be positioned at the center of the body pad 100 and may have a width greater than or equal to a predetermined value. A section including the largest width of the body pad 100 except for the contact portion 180 may be included in the front portion 140 . In particular, in a preferred embodiment of the present invention, the front portion 140 may be positioned between the convex portions of the outer edges 120 on both sides of the body pad 100 .

The arch support portion 160 may be located on the upper portion of the front portion 140 , and the distance between the coupling lines 190 formed on both sides may decrease toward the upper portion. In FIG. 1 , a portion in which the distance between the coupling lines 190 at a position corresponding to the upper end of the arch support unit 160 is minimized is indicated by a double-headed arrow.

As shown in FIG. 2 , if the distance between the coupling lines 190 on both sides in the front part 140 already has a width that decreases toward the upper side, the distance between the coupling lines 190 in the arch support unit 160 is further reduced. can That is, the angle formed by the coupling line 190 with respect to the vertical direction may increase in the arch support portion 160 than in the front portion 140 .

In the embodiment shown in FIGS. 1 to 5 , the outer edge 120 of the arch support unit 160 is formed along the coupling line 190 , so that the width of the arch support unit 160 also decreases toward the top.

The lower support part 145 may be located below the front part 140 . The width of the lower support portion 145 may be smaller than that of the front portion 140 , may be the same, or may be larger than that of the front portion 140 . In the example shown in FIG. 2 , the lower support part 145 has a width that decreases toward the bottom. In some embodiments, the front portion 140 and the lower support portion 145 may be viewed as extending to the lower edge 130 without being particularly distinguished.

According to an embodiment of the present invention, the left and right outer edges 120 of the body pad 100 are curved in the arch support part 160 , the front part 140 , and the lower support part 145 , so that the It may be formed so that the width in the horizontal direction at the height of the middle portion is greater than the width in the horizontal direction at the upper side and the lower side. That is, in the portion excluding the contact portion 180 , the middle portion of the body pad 100 may be formed to have an outwardly convex shape compared to the upper and lower sides, and this portion may belong to the front portion 140 .

The close contact unit 180 may be located above the arch support unit 160 . The close contact unit 180 may have a width greater than the distance between the coupling lines 190 on both sides at the upper end of the arch support unit 160 . Referring to FIG. 1 , it can be seen that the width of the close contact portion 180 is larger than the portion where the distance between the coupling lines 190 at the upper end of the arch support portion 160 is minimized, as indicated by an arrow. As in the embodiment shown in FIGS. 1 to 5 , when the outer edge 120 is formed along the coupling line 190 in the arch support 160 and the width of the arch support 160 decreases toward the top, the main body The outer edges 120 of both sides of the pad 100 may form side grooves 165 at a portion corresponding to the boundary between the contact portion 180 and the arch support portion 160 .

The close contact unit 180 may serve to provide a space for mounting the nose bridge support piece 380 . The bridge of the nose support piece 380 may be formed of a material such as metal that is elastically deformable and capable of providing a required level of strength, and may be mounted on the upper portion of the body pad 100 . A user wearing the mask 1000 may bend the bridge of the nose support piece 380 according to the shape of the bridge of the nose so that the upper part of the mask 1000 is in close contact with the bridge of the user's nose. A reference groove 105 may be formed in the upper portion of the contact portion 180 . The reference groove 105 may be formed at a position corresponding to the user's nose bridge, and the nose bridge support piece 380 is bent to both sides in the reference groove 105 so that the contact part 180 is effectively in close contact with both sides of the user's nose bridge. can do. In some embodiments, the reference groove 105 may be omitted.

In the mask 1000 according to the first embodiment of the present invention, the opening 150 may be formed in the body pad 100 , and the window member 350 may be mounted in the opening 150 . The window member 350 may be formed of a transparent material, and may have a thickness that can be elastically bent. The opening 150 may be formed over any one or more of the front portion 140 , the arch support portion 160 , and the lower support portion 145 in the body pad 100 , and the window member 350 allows air to enter. It may be hermetically coupled to the opening 150 so as not to do so. According to an embodiment of the present invention, the area of the opening 150 may correspond to 60% or more of the total area of the body pad 100 including the area of the opening 150 .

As shown in FIG. 5 , the opening 150 and the window member 350 mounted thereon are formed over the front part 140 and the arch support part 160 , and in particular, the area of the opening 150 is the body pad 100 . ) If it reaches 60% or more of the total area, both the nose and mouth of the user wearing the mask 1000 are visible from the outside, making it easier for others to distinguish who the user is.

The skirt part 200 is a member coupled to each of the left and right sides of the body pad 100 , and may be coupled along the coupling line 190 , and when the mask 1000 is used, the skirt part 200 is bent along the coupling line 190 . can be The skirt part 200 may be formed of the same material as the body pad 100 , and may include a material such as nonwoven fabric, fabric, rubber, silicone, soft plastic resin, or the like.

The shape of the skirt 200 may be defined by an outer edge 210 and an inner edge 220 . Here, the outer edge 210 of the skirt part 200 is referred to as including the upper and lower edges of the skirt part 200 . The inner edge 220 of the skirt part 200 refers to an edge of the portion facing the body pad 100 . In the illustrated embodiment, the inner edge 220 of the skirt portion 200 is formed adjacent to the outer edge 120 of the body pad 100 in a shape corresponding to.

The upper and lower portions of the skirt portion 200 in contact with the body pad 100 may be configured to extend from the upper and lower portions of the body pad 100 , respectively, and to decrease in length in the longitudinal direction while facing outward. The skirt part 200 may include a protrusion 280 (refer to FIGS. 14 and 15) formed thereon, the protrusion 280 may be coupled to the outer end of the contact part 180, and a shape corresponding thereto can have The fusion line 192 formed along the outer edge of the protrusion 280 serves to couple the protrusion 280 to the outer end of the contact unit 180 , but the skirt 200 is bent with respect to the body pad 100 . Since it is not intended to be used, it will be expressed separately from the above-described coupling line 190 .

On the side of the skirt unit 200, the wearing string 300 may be coupled or connecting portions 232 and 234 for coupling the wearing string may be formed. The user may wear the mask 1000 over the ear with the wearing string 300 . The skirt part 200 transmits a tensile force to the body pad 100 when the skirt part 200 is pulled from the wearing string 300 region so that the body pad 100 maintains an arcuate shape, and also the body pad 100 of the body pad 100 . It may serve to seal the tent space from both sides.

The coupling line 190 coupling the body pad 100 and the skirt 200 may be formed by fusion, sewing, or other methods. For example, when the body pad 100 and the skirt part 200 are made of a non-woven fabric of a meltable polymer, the body pad 100 and the skirt part 200 are overlapped with each other along the bonding line 190 to provide a necessary degree of heat. When , the body pad 100 and the skirt part 200 are coupled along the coupling line 190 , and at the same time, an unnecessary portion beyond the outer edge 120 of the body pad 100 may be cut and separated. Unless otherwise specified in the present specification, the reference to fusion refers to a bonding method encompassing not only fusion but also other methods such as sewing, bonding, and bonding.

The left and right coupling lines 190 are formed in a curve along the outer edge 120 of the body pad 100 as shown in the figure so that the horizontal width at the front part 140 of the body pad 100 is greater than or equal to a predetermined value. can be formed. That is, the coupling line 190 may also be formed in an outwardly convex shape, in response to the body pad 100 having an outwardly convex shape compared to the upper and lower sides of the body pad 100 except for the close contact portion 180 .

The coupling line 190 not only couples the body pad 100 and the skirt part 200 to each other, but also forms a part where the skirt part 200 is bent with respect to the body pad 100, and the position, number, The three-dimensional geometric shape of the mask 1000 may vary according to the shape, angle, and spacing of the adjacent coupling lines 190 . Meanwhile, the mask 1000 may include various fusion lines 115 , 135 , and 215 in addition to the coupling line 190 for the purpose of coupling the body pad 100 and the skirt 200 to each other. The fusion lines 115 , 135 , and 215 are formed by applying fusion, sewing, etc. to a member at a position such as the edge of the body pad 100 or the skirt 200 , and may serve to reinforce the corresponding portion.

The wearing string 300 may be coupled to the connecting portions 232 and 234 of the skirt unit 200 , and the user may wear the mask 1000 by hanging the wearing string 300 over the ear. When the user wears the mask 1000 , the wearing string 300 applies tension to the skirt part 200 and the body pad 100 .

Referring to FIG. 4 , which exemplarily shows the wearing state of the mask 1000 according to the first embodiment of the present invention, when the user wears the mask 1000, the upper edge 110 of the body pad 100 is The front part 140 of the body pad 100 may be positioned on the user's mouth, and the lower edge of the body pad 100 may be positioned on the front side of the user's chin.

As described above, since the body pad 100 and the skirt 200 are configured to have a larger width in the middle than the upper and lower portions, the user wears the mask 1000 and the wearing string 300 is the skirt When tension is applied to the part 200 and the body pad 100 , a portion having a larger width along the horizontal direction becomes convex forward compared to a portion having a smaller width. Meanwhile, while the body pad 100 is bent in the vertical direction, it is possible to maintain a state in which it is not bent in the horizontal direction.

Accordingly, the body pad 100 forms a convex arch-shaped cross section in the longitudinal direction as a whole and maintains a straight cross section in the transverse direction, and in particular, the front portion 140 of the body pad 100 is located at the frontmost position. can do. That is, as shown in the cross-sectional views of FIGS. 3 and 4 , the body pad 100 can maintain a straight line in the horizontal direction at one or more points of the corresponding arc shape even in a state in which it is bent in an arcuate shape in the vertical direction. Similarly, the skirt part 200 may have an arcuate cross section in the vertical direction, but may maintain a straight line in the horizontal direction at one or more points of the corresponding arcuate shape.

This structure allows the body pad 100 to form a kind of dome-type tent space in front of the user's nose and mouth. Since the space in front of the user's nose and especially the mouth is maintained, the possibility that the user's nose and mouth will come into contact with the mask 1000 is reduced even if the user moves his/her mouth while wearing the mask 1000 .

In addition, since the body pad 100 is supported by the user's face at a point in the vertical direction rather than by the user's face at a point in the horizontal direction, the body pad 100 is not supported by the user's face at a point in the vertical direction, unlike a conventional mask. There is no need to extend to the lower jaw. Since the body pad 100 only needs to maintain a convex arch shape forward in the longitudinal direction in a state in which the skirt part 200 is supported from both sides, the lower surface of the body pad 100 is caused by the portion under the user's mouth, that is, It is sufficient to be supported by the front of the chin.

The existing mask is supported by the user's nose bridge and both sides of the face, so the mask had to extend beyond the user's cheeks in the horizontal direction. had to be expanded. On the other hand, in the mask 1000 having a vertical body pad according to an embodiment of the present invention, the body pad 100 is supported by the user's nose bridge and the front part of the chin to maintain an arch shape, and the skirt 200 is Since it is only necessary to seal the side surface of the arch shape, the body pad 100 does not need to extend below the chin, and the skirt 200 does not need to extend beyond the user's both cheeks. As the width in the horizontal direction of the skirt portion 200 is reduced, the length of the wearing string 300 may be increased.

On the other hand, if the body pad 100 does not include the contact part 180, the nose bridge support piece 380 is limited to a length corresponding to a very narrow width of the upper end of the arch support part 160, or the nose bridge support piece 380. It will have to extend beyond the outer edge 120 of the body pad 100 . However, when the bridge of the nose support piece 380 is formed to a length less than the length of the upper end of the arch support part 160, the bridge of the nose support piece 380 does not provide a sufficient length for close contact with the user's nose and face, and the bridge of the nose support piece ( When the 380 is extended beyond the outer edge 120 of the body pad 100 , the exposed bridge of the nose support piece 380 may be caught by another object and may damage the mask 1000 itself or an external object. If the bridge of the nose support piece 380 is also coupled to the skirt part 200 through the body pad 100 , the mounting and use of the bridge of the nose support piece 380 becomes excessively complicated.

In order to solve this problem, the body pad 100 may separately include the contact part 180 on the upper part of the arch support part 160 so that the bridge of the nose support piece 380 can be completely accommodated in the contact part 180 . have. The close contact portion 180 may be formed to have a length greater than that of the nose bridge support piece 380 , thereby preventing the edge of the nose bridge support piece 380 from being caught by an external object. The bridge of the nose support piece 380 may be inserted between the outer fabric and the cloth in the close contact portion 180 , or may be coupled to the outer surface of the outer fabric or the inner surface of the lining. A separate fusion line 185 may be formed at the mounting position of the nose bridge support piece 380 in the close contact portion 180 , which indicates the position of the nose bridge support piece 380 or fixes the nose bridge support piece 380 . can contribute to In the illustrated embodiment, fusion lines 185 are formed on the upper and lower portions of the nose bridge support piece 380 , respectively.

14 and 15 , both ends of the contact part 180 may be coupled to the protrusion part 280 of the skirt part 200 . As a part of the body pad 100 and a part of the skirt part 200 overlap at both ends of the contact part 180, the corresponding part may have higher rigidity, and the contact part 180 at the corresponding position is the face of the user. can be better adhered to. This can more effectively block the user's exhalation from leaking from the location, thereby preventing the exhalation containing a large amount of moisture from being directed toward the glasses or the like.

On the other hand, as shown in FIGS. 14 and 15 (b) and (c), in the front portion 140, the arch support portion 160 and the lower support portion 145 portion, the body pad 100 and the skirt portion 200 ) is formed along the outer edge 120 of the body pad 100 and the inner edge 220 of the skirt portion 200, but in the contact portion 180, the coupling lines 194 and 196 are in close contact. It may be formed at a position spaced apart from the end of the part 180 . That is, the coupling lines 194 and 196 in the contact part 180 are from the side groove 165 positioned at the boundary between the contact part 180 and the arch support part 160 to the upper edge 110 of the body pad 100 . It may be configured to follow.

In some embodiments, similar to the mask 1000b shown in (b) of FIG. 15 , the angle or curvature of the engagement line 194 in the close contact portion 180 is at the upper portion of the arch support unit 160 . can keep This has the effect of narrowing the upper end of the portion that forms the dome-type tent space in front of the user's nose and mouth of the body pad 100, so that the dome-type tent space (ie, the front portion 140) protrudes further forward .

In some embodiments, similar to the mask 1000c shown in (c) of FIG. 15 , the coupling line 196 in the close contact unit 180 extends vertically upward from the upper portion of the arch support unit 160 . can This allows the domed tent space by the body pad 100 to form a space of sufficient size in front of the user's nose and mouth, while the upper end is in close contact with the bridge of the nose support piece 380 over a larger length. Of course, the present invention is not limited thereto, and in some embodiments, similar to the mask 1000a shown in FIG. up to) may be extended.

As described above, the wearing string 300 applies tension to the skirt part 200 and the body pad 100 , which causes the skirt part 200 and the body pad 100 to form a dome-shaped space. Each of the wearing straps 300 may have both ends coupled to the upper connection part 232 and the lower connection part 234 of the skirt part 200 . In a preferred embodiment of the present invention, the position at which the wearing string 300 is coupled, that is, the position of the connection portions 232 and 234 may be formed at a height corresponding to the front portion 140 .

For example, in FIG. 5 , heights corresponding to the upper and lower portions of the front portion 140 are indicated by dashed-dotted lines. In the embodiment shown in FIG. 5 , the position of the upper connection part 232 to which one end of the wearing string 300 is coupled is formed at a height corresponding to the upper portion of the front part 140 , and the other end of the wearing string 300 is The position of the lower connecting portion 234 to be coupled is formed at a height corresponding to the upper portion of the front portion (140). This structure allows one end of the wearing string 300 to be coupled to a position close to the upper bent part where the mask 1000 is bent in FIG. 4, and the wearing strap 300 to a position close to the lower bent part where the mask 1000 is bent. make the other end of the

When the position of the connection part 232 to which one end of the wearing string 300 is coupled is formed at a position higher than the upper portion of the front part 140 , the body pad 100 forms a dome-shaped space, but the body pad 100 . Wrinkles may occur in the arch support portion 160 and the skirt portion 200 on both sides thereof. Similarly, when the position of the connection part 234 to which the other end of the wearing string 300 is coupled is formed at a position lower than the lower part of the front part 140, the body pad 100 forms a dome-shaped space, but the body pad ( 100), wrinkling may occur in the lower support portion 145 and the skirt portion 200 on both sides thereof. When wrinkling occurs in the arch support 160 and/or the lower support 145 , it may be difficult for the mask 1000 to fully adhere to the user's face, and unintentional air communication through the edge of the mask 1000 may occur. can occur

As described above, the mask 1000 according to the first embodiment of the present invention can be implemented in a significantly smaller area by reducing the length in the vertical direction and the width in the horizontal direction as compared to the existing mask. Since the mask 1000 is implemented with a smaller area, the manufacturing cost of the mask 1000 can also be reduced, and even from the perspective of a user wearing the mask 1000, the exposed portion of the face is relatively increased, so that visibility of who the wearer is This can be improved. In particular, when the window is formed by forming the opening 150 in the body pad 100 of the mask 1000, since the body pad 100 extends in the vertical direction, both the user's nose and mouth are visible from the outside. There is this.

Since the mask 1000 according to the first embodiment of the present invention does not need to extend below the user's chin, the position of the mask 1000 does not change significantly even when the user moves his or her mouth like when speaking. The inconvenience of having to re-adjust the The connection parts 232 and 234 to which the wearing strap 300 of the mask 1000 are coupled are formed at a height corresponding to the front portion 140 of the body pad 100 so that the body pad 100 maintains an intact dome-shaped shape. can In addition, the body pad 100 includes an arch support portion 160 that becomes narrower toward the top to form a dome-shaped shape, but includes a separate contact portion 180 for accommodating the bridge of the nose support piece 380, so that the user It is possible to effectively prevent the occurrence of unintentional airflow around the bridge of the nose.

6 is a front view exemplarily showing a mask 1200 according to a second embodiment of the present invention. The mask 1200 according to the second embodiment of the present invention has a number of common features with the mask 1000 according to the first embodiment described above, and the following will focus on the differences between the mask 1200 according to the second embodiment to explain Features described in relation to the first embodiment may be applied to the second embodiment, and likewise features described in relation to the second embodiment may be applied to the first embodiment. Some reference numbers mentioned in describing the second embodiment are intended to refer to components corresponding to the components to which the reference numbers are applied to the first embodiment.

Referring to FIG. 6 , the mask 1200 according to the second embodiment of the present invention may largely include a body pad 100 , a skirt part 200 , a wearing strap 300 , and a bridge of the nose support piece 380 . , the body pad 100 may include a front portion 140 and an upper support portion 170 .

The front portion 140 of the mask 1200 may be located at the center of the body pad 100 , and may be coupled to the skirt portions 200 on both sides by the coupling lines 190 formed along the outer edge 120 . have.

On the other hand, the upper support portion 170 positioned above the front portion 140 may be coupled to the skirt portion 200 at the coupling line 195 and the side fusion line 197 . Here, the side fusion line 197 may be formed along the outer edge 120 , and the bonding line 195 may be formed inside the outer edge 120 . That is, in the mask 1200 according to the second embodiment of the present invention, the body pad 100 and the skirt 200 are connected to the coupling line 195 and the side portion at the portion corresponding to the upper support portion 170 of the body pad 100 . It may be joined by all of the fusion lines 197 . Of course, in this case, the skirt part 200 in the upper support part 170 will be bent with respect to the body pad 100 at the coupling line 195 located further inside.

The coupling line 195 may extend from the coupling line 190 formed on the front part 140, and form a larger angle with respect to the vertical direction as in the example shown in FIG. 6 and be formed along a straight line inclined inward. can Of course, the shape, angle, curvature, etc. of the coupling line 194 may be variously designed as needed. The three-dimensional geometric shape of the mask 1200 may vary depending on the position, shape, angle, etc. of the coupling line 195 .

The upper support unit 170 has a coupling line 195 and a side fusion line 197 formed together, but the position where the coupling line 195 and the side fusion line 197 start must be viewed as the starting point of the upper support unit 170. none. That is, the coupling line 195 and the side fusion line 197 do not necessarily start from the lower part of the upper support part 170 , and may start at any point of the upper support part 170 .

As the coupling line 195 and the side fusion line 197 are formed together on the upper support portion 170, rigid regions with increased rigidity may be formed on both sides of the upper support portion 170 in the left and right directions. The rigid region (no reference number) refers to the region between the bonding line 195 and the side fusion line 197. The rigid region is a relatively narrow area in which the skirt 200 is additionally padded, and the left and right sides are It has increased rigidity due to reinforcement by the bonding line 195 and the side fusion line 197 .

Although not shown, in some embodiments, a reinforcing fusion line (not shown) may be further formed in the rigid region. The reinforcing fusion line may be formed at a predetermined interval between the bonding line 195 and the side fusion line 197 . When the body pad 100 is formed of a non-woven fabric material and the reinforcing fusion line is formed by thermally fusing the outer fabric, lining and filter of the body pad 100, it may be advantageous for the reinforcing fusion line to extend in the longitudinal direction. . Here, the vertical direction is intended to encompass not only a direction that is exactly vertical but also a direction that is inclined at a predetermined angle with respect to the vertical. The reinforcing fusion line may be formed along a direction inclined at an angle between, for example, the angle of the bonding line 195 and the angle of the side fusion line 197 . Of course, the reinforcing fusion line may be formed in a direction intersecting the bonding line 195 and/or the side fusion line 197 .

A nose bridge support piece 380 may be mounted on the upper support part 170 . As in the first embodiment, the bridge of the nose support piece 380 may be formed of a material such as metal that is elastically deformable and can provide a required level of strength, and is to be mounted on the upper portion of the body pad 100 . can

Since rigid regions with higher rigidity are formed on both sides of the upper support portion 170, in one embodiment of the present invention, the bridge of the nose support piece 380 is located between the rigid regions on both sides, that is, between the coupling lines 195 on both sides. It may be formed in a length to be positioned. Of course, in some embodiments, the bridge of the nose support piece 380 is formed to a length extending to the outer edge 120 , and the coupling line 195 extends only below the bridge of the nose support piece 380 , or below the bridge of the nose support piece 380 . After extending to the top of the bridge of the nose support piece 380 may be continued.

On the other hand, even if the bridge of the nose support piece 380 extends only between the rigid regions as in the second embodiment of the present invention shown in FIG. 6, the rigid region between the coupling line 195 and the side fusion line 197 has high rigidity. Therefore, the body pad 100 of the rigid region can maintain a state parallel to the end of the bridge of the nose support piece 380 . This in turn provides an effect similar to that the rigid region itself extends the nasal bridge support piece 380 further, and provides the same close contact effect even if the nasal bridge support piece 380 is formed with a shorter length compared to the case where the rigid region is not formed. means you can

Although not shown in FIG. 6 , a bent portion extending in the horizontal direction may be formed at a predetermined position of the rigid region formed between the bonding line 195 and the side fusion line 197 . The bent part may be implemented in the form of a bending fusion line 162 (refer to FIG. 9 ) in which the body pad 100 and the skirt part 200 are fused to each other at the corresponding position, or may be implemented in the form of an incision through which the corresponding position is cut. may be The bending portions on both sides may include two or more bending fusion lines 162 and 164 or two or more incision lines, respectively.

The rigid region on both sides of the upper support portion 170 has increased rigidity, so it may not be easy to bend the corresponding region. can make it For example, when the body pad 100 is formed of a non-woven fabric and the bent portion is implemented in the form of a bending fusion line 162 by thermal fusion, the bending fusion line 162 has a thin thickness of 0.1 to 0.3 mm and is bent. Bending at the part becomes possible. In addition, when the bent portion is implemented in the form of a cut line and the corresponding position is cut, the high rigidity is not naturally maintained at the corresponding position, so that bending at the bent portion is possible.

When the bent portion is formed in the upper support portion 170 , the upper portion of the upper support portion 170 may be relatively bent with respect to the lower portion of the upper support portion 170 in the bent portion. As a result, the upper support portion 170 may be divided into the arch support portion 160 and the close contact portion 180 described in relation to the first embodiment based on the bending line. The lower portion of the bent portion of the upper support portion 170 corresponds to the arch support portion 160 and may serve to support the dome-shaped space, and the portion of the upper portion of the bent portion of the upper support portion 170 corresponds to the contact portion 180. Corresponding to this, it can serve to adhere to the user's nose bridge and face. For this reason, it is preferable that the nose bridge support piece 380 is mounted at a position higher than the bent portion.

For reference, as shown in FIG. 6 , in a state in which the bridge of the nose support piece 380 is provided, the bent part is formed at the same position as the bending fusion lines 162 and 164 of FIG. The side grooves 165 described in relation to the first embodiment may be formed, and the overall shape of the mask 1200 may be similar to that of the mask 1000 according to the first embodiment of the present invention.

As such, the mask 1200 according to the second embodiment of the present invention may be formed so that both sides of the upper body pad 100 , that is, both sides of the upper support part 170 , have increased rigidity. This provides the same effect as if the nasal bridge support piece 380 increased the length of the nose bridge support piece 380 even if the nose bridge support piece 380 has a small length, so that the mask 1200 can better adhere to the wearer's face. .

In addition, in the mask 1000 according to the first embodiment of the present invention, the side grooves 165 are formed because the adhesion portion 180 and the arch support portion 160 have significantly different widths, and the body pad 100 is unique. will have a shape. In contrast, in the mask 1200 according to the second embodiment of the present invention, the contact portion 180 and the arch support portion 160 are not clearly distinguished from the upper support portion 170, and the body pad 100 has a continuous side portion. It can form a better appearance for consumers who prefer a typical design.

7 is a cross-sectional view exemplarily showing a wearing state of a mask according to an embodiment of the present invention. Hereinafter, an approach to a method for allowing the mask to adhere to the wearer's face 20 will be described with reference to FIG. 7 .

As described above, in the mask according to an embodiment of the present invention, when tension is applied to the skirt portion 200 due to the wearing string 300, the body pad 100 can form a dome-shaped space around the user's nose. have. In order for the body pad 100 to form a dome-shaped space, the body pad 100 must be formed of a material having a predetermined rigidity.

In order for the mask to be in close contact with the user's face 20, it is required to make a contact with the user's nose bridge 25 and the face 20 along the line L1 of FIG. 7 while forming a curve. However, since the body pad 100 has rigidity to form a dome-shaped space, the upper portion of the body pad 100 is taut on both sides of the bridge of the nose 25 along the line L2 of FIG. 7 in the absence of other measures. will be pulled The masks 1000 and 1200 according to the first and second embodiments of the present invention include a bridge of the nose support piece 380, and the user bends the bridge of the nose support piece 380 along the line L1 of FIG. The upper part of (1000, 1200) is brought into close contact with the user's nose bridge (25) and face surface (20).

On the other hand, as another approach for making the mask closely adhere to the user's nose bridge 25 and face surface 20, there is a method in which the body pad 100 maintains generally high rigidity but has elasticity only in part. That is, in FIG. 7 , the length of the line L1 is greater than the length of the line L2 , which is due to the curvature caused by the nose 25 protruding from the face 20 . If only the bridge of the nose 25 can be stretched in the horizontal direction, it becomes possible to make the mask closely adhere to the wearer's face even without using the bridge of the nose 380 as described above.

8 is a front view exemplarily showing a mask 1300 according to a third embodiment of the present invention. The mask 1300 according to the third embodiment of the present invention has a number of common features with the masks 1000 and 1200 according to the first and second embodiments described above. Hereinafter, the mask 1300 according to the third embodiment The differences will be mainly explained. Features described in relation to the first and second embodiments may be applied to the third embodiment, and likewise features described in relation to the third embodiment may be applied to the first and second embodiments. Some reference numbers mentioned in describing the third embodiment are intended to refer to components corresponding to the components to which the reference numbers are applied to the first and second embodiments.

Referring to FIG. 8 , the mask 1300 according to the third embodiment of the present invention may largely include a body pad 100 , a skirt part 200 , and a wearing strap 300 , and the body pad 100 is It may include a front part 140 and an upper support part 170 .

The front portion 140 of the mask 1300 may be located in the middle portion of the body pad 100 , and may be coupled to the skirt portions 200 on both sides by the coupling lines 190 formed along the outer edge 120 . have. The upper support portion 170 may be located on the upper portion of the front portion 140 , and a coupling line 195 and a side fusion line 197 may be formed. As described above, for convenience of description, the region between the bonding line 195 and the side fusion line 197 is referred to as a rigid region, because the region has increased rigidity.

According to the third embodiment of the present invention, cutouts 172 and 174 may be formed in the body pad 100 . The cutouts 172 and 174 correspond to portions where the body pad 100 is cut in the longitudinal direction. As described above, the vertical direction is intended to encompass not only a direction that is exactly vertical but also a direction that is inclined at a predetermined angle with respect to the vertical.

As described with reference to FIG. 7, by making the body pad 100 stretch in the horizontal direction at a specific position, it is possible to make the mask 1300 closely adhere to the wearer's face without the nose bridge support piece 380. 172 and 174 are portions cut in the vertical direction in the body pad 100 and serve to extend the body pad 100 in the horizontal direction.

As in the example shown in FIG. 8 , the cutouts 172 and 174 may include one or more cutouts 172 formed in a vertical direction and one or more cutouts 174 formed in an inclined direction, which are formed in a vertical direction. considered to be formed. The position, number, and angle of the cutouts 172 and 174 may be designed in various ways according to the extent and shape of the body pad 100 at the corresponding position. For example, in FIG. 8 , two cutouts 172 formed in a vertical direction and two cutouts 174 formed in an inclined direction are formed in FIG. 8 , but in another embodiment, different numbers of cutouts 172 and 174 are formed ) may be provided, and in some embodiments, only one cutout 172 may be formed.

In general, when a part of the mask is incised, communication of air may occur to the incision, and there is a risk that the mask may lose its original function of filtering incoming air. , 174) is formed at a position corresponding to the user's nose bridge 25, whereby the cutouts 172 and 174 are blocked by the user's nose bridge 25, and the air through the cutouts 172 and 174 communication does not occur. However, it may be advantageous to limit the length of the cutouts 172 and 174 to more reliably prevent the communication of air through the cutouts 172 and 174 . When the length of the cut-outs 172, 174 is limited to not exceed 40 mm, air communication through the cut-outs 172, 174 does not easily occur.

The cutouts 172 and 174 are preferably formed on the upper support portion 170 of the body pad 100 , and the body pad 100 of the mask 1300 is placed on the user's nose bridge 25 from the upper support portion 170 . This is because both sides of the upper support portion 170 are reinforced by the bonding line 195 and the side fusion line 197 to form a rigid region. The cutout portions 172 and 174 may be formed over the arch support portion 160 and the contact portion 180 of the upper support portion 170 . As long as the cutouts 172 and 174 can be blocked by the user's nose bridge 25 and the body pad 100 does not interfere with forming a dome-shaped space when the mask 1300 is worn, the cutouts 172, 174 may be formed on the front surface 140 of the body pad 100 .

As described above, the mask 1300 according to the third embodiment of the present invention includes the cutouts 172 and 174 formed in the body pad 100 so that the body pad 100 can be stretched in the horizontal direction. The cutouts 172 and 174 are formed at positions corresponding to the nose bridge 25 of the user who wears the mask 1300, and the cutouts 172 and 174 are blocked by the user's nose bridge 25 so that the cutouts ( While preventing air from communicating through the 172 and 174 , it allows the body pad 100 to be stretched only in the portion of the nose bridge 25 protruding from the face 20 .

As a result, the body pad 100 having a predetermined rigidity as a whole can form a dome-shaped space around the user's nose and mouth as described above, and at the same time stretch only the user's nose bridge 25 in the horizontal direction, and the nose bridge support piece 380 ), the mask 1300 can be in close contact with the user's face. Since the upper portion of the body pad 100 is in close contact with the user's face and the cutouts 172 and 174 are in close contact with the user's nose bridge 25, the dome-shaped space can be kept sealed, and the user can use the mask 1300. You can breathe the air that goes through the filter.

9 is a front view exemplarily showing the body pad 100 of the mask 1400 according to the fourth embodiment of the present invention. The mask 1400 according to the fourth embodiment of the present invention has a number of common features with the masks 1000 , 1200 , and 1300 according to the first to third embodiments described above. Hereinafter, the mask according to the fourth embodiment ( 1400) will be mainly explained. Features described in relation to the first to third embodiments may be applied to the fourth embodiment, and likewise features described in relation to the fourth embodiment may be applied to the first to third embodiments. Some reference numbers mentioned in describing the fourth embodiment are intended to refer to components corresponding to the components to which the reference numbers are applied to the first to third embodiments.

The mask 1400 according to the fourth embodiment of the present invention may largely include a body pad 100 , a skirt part 200 , and a wearing strap 300 , and the body pad 100 includes a front part 140 and An upper support portion 170 may be included. Only the body pad 100 is shown in FIG. 9 for better understanding.

The mask 1400 according to the fourth embodiment of the present invention may also include cutouts 174 and 176 formed in the upper support portion 170 . However, in the embodiment shown in Fig. 8, the cutouts 172 and 174 are both formed in a linear shape, whereas in the embodiment shown in Fig. 9, the cutout 176 is implemented in the form of a figure having a predetermined area. . The cutout 176 implemented in the shape of a figure having a predetermined area as described above allows the body pad 100 to be more easily stretched. In a preferred embodiment of the present invention, the cutout 176 having a predetermined area is formed in the center and has a relatively narrow width so that the cutout 176 is placed on the nose bridge 25 of the user wearing the mask 1400. can be ensured to be blocked by

When the cutout 176 has a rhombic shape as shown in FIG. 9 , the body pad 100 may be more effectively stretched and contracted, but the shape of the cutout 176 is not necessarily limited to a rhombic shape. In some embodiments not shown, the cutout 176 may be formed in other polygonal, oval, or the like shapes.

6, in the mask according to an embodiment of the present invention, bent portions may be formed on both sides of the upper support portion 170 in a horizontal direction, and the bent portions are in the form of a bent fusion line and/or an incision line. can be implemented as As described above, the rigid region on both sides of the upper support portion 170 has increased rigidity, so it may not be easy to bend the corresponding region. do.

In FIG. 9, the bending portions on both sides consist of two bending fusion lines 162 and 164, respectively. One bending welding line 162 is formed in the horizontal direction between the bonding line 195 and the side welding line 197, and the other bending welding line 164 forms a predetermined angle at the end of the bending welding line 162. is inclined in the direction. Even if each bending portion of the body pad 100 includes only one of these two types of bending welding lines 162 and 164 , bending may occur at the corresponding bending welding lines 162 and 164 , but two types extending in the intersecting direction By using the bending fusion lines 162 and 164 together, the degree of freedom with respect to the bending direction and position is increased.

As the upper support part 170 is bent at the bent part, the upper support part 170 may be divided into the arch support part 160 and the close contact part 180 based on the bending line. The lower portion of the bent portion of the upper support portion 170 corresponds to the arch support portion 160 and may serve to support the dome-shaped space, and the portion of the upper portion of the bent portion of the upper support portion 170 corresponds to the contact portion 180. Corresponding to this, it can serve to adhere to the user's nose bridge and face.

The cutout portions 174 and 176 are formed in the upper support portion 170 so that the body pad 100 can be stretched in the horizontal direction in the corresponding portion, and at the same time, the contact portion 180 corresponding to the portion above the bent portion is the user's It may be in close contact with the bridge of the nose 25 and the face 20 by making an interview. That is, when the bent portion is not formed as in the embodiment shown in FIG. 8 , the upper portion of the body pad 100 contacts the user's nose bridge 25 and the face surface 20 by the upper edge 110 to make a relatively small area, which may not provide a comfortable fit to the user. However, as in the embodiment shown in FIG. 9 , if the rigid region of the upper support part 170 is configured to be bent at the bent part, the entire contact part 180 is brought into contact with the user's face to make surface contact over a wider area. This can occur, and as a result, the user can feel comfortable wearing it.

10 is a flowchart exemplarily illustrating a mask manufacturing method according to an embodiment of the present invention, and FIGS. 11 to 15 are plan views illustrating processing operations related to the mask manufacturing method according to an embodiment of the present invention. 11 to 15 are depicted based on the mask 1000 according to the first embodiment described above, but similarly to the manufacture of the masks 1200, 1300, and 1400 according to the second to fourth embodiments of the present invention. can be applied.

For reference, an arrangement when the mask 1000 is worn is assumed in FIGS. 1 to 9 , whereas an arrangement when the mask member 10 and the mask 1000 are manufactured is assumed in FIGS. 11 to 15 . Thus, the mask 1000 depicted in FIG. 15 corresponds to the back surface of the mask 1000 depicted in FIG. 1 , but FIG. 1 is represented in a front view whereas FIG. 15 is represented in a plan view.

The method for manufacturing a mask according to an embodiment of the present invention shown in FIG. 10 is coupled to each of the left and right sides of the body pad 100 extending in the longitudinal direction and the body pad 100 in the transverse direction, as described above, and includes a coupling line 190 . This is a method of manufacturing the mask 1000 including the skirt portion 200 bent along the The mask manufacturing method according to an embodiment of the present invention may be automatically performed by a manufacturing apparatus configured for this purpose.

Referring to FIG. 10 , the method for manufacturing a mask according to an embodiment of the present invention may include the step of transferring the mask member 10 ( S510 ). The mask member 10 may be provided in a longitudinally elongated form. For example, the mask member 10 may be provided in the form of being wound on a roll (not shown), and may be configured to be unwound from the roll (not shown) while the mask member 10 is pulled and transported. When the mask member 10 is composed of a plurality of material layers such as an outer material, a filter, and a lining, each material layer may be provided in the form of being wound on an individual roll (not shown), and the material layers may be overlapped and processed. have. In this way, the step ( S510 ) of transferring the mask member may be performed together with other steps of processing the mask member ( 10 ). Of course, various methods may be used to transport the mask member 10 .

With respect to the transferred mask member 10 , a step ( S520 ) of primarily cutting the mask member 10 may be performed. In the case of the mask member 10 being transported in a manner such as being unwound from a roll, the manufacturing apparatus may allow the mask member 10 to pass through a cutter roller or the like so that the primary cutting is applied.

11 exemplarily shows the step (S520) of primarily cutting the mask member in the method for manufacturing a mask according to an embodiment of the present invention. 11 shows a portion of the mask member 10 elongated in the longitudinal direction. The mask member 10 may be processed while being transported in a direction (eg, upward or downward in FIG. 11 ) unwinding from a roll (not shown), and one mask for each predetermined interval of the mask member 10 . (1000) can be prepared.

In FIG. 11, the folding line 19 is also represented by a dashed-dotted line, which corresponds to a portion where the mask member 10 is folded in a later step. For reference, the central portion 15 between the two fold lines 19 in the mask member 10 forms the body pad 100 of the mask 1000 when manufacturing is completed, and each fold line 19 and the mask member The portion between the edges of (10) (one side 12 and the other side 17 of the mask member 10) forms the skirt portion 200 of the mask 1000 when manufacturing is completed.

The step of first cutting the mask member 10 ( S520 ) may include cutting along the outer edge 210 of the skirt part 200 at one side 12 and the other side 17 of the mask member 10 . can In the case of one extended mask member 10 as shown in FIG. 11 , a cutting line 11 may also be formed between portions cut along the skirt portion 200 of each unit mask, and thus the skirt portion 200 . The outer portion of the portion cut along the outer edge 210 of the may be separated from the mask member 10 and removed.

The mask manufacturing method according to an embodiment of the present invention may include forming a fusion line at a required position of the mask member 10 . In the step of forming the fusion line, the fusion lines 115, 135, 185, excluding the bonding lines 190, 194, 195, 196 and the side welding lines 197 to which the body pad 100 and the skirt 200 are coupled to each other, 215) may be formed. The step of forming the fusion line may be performed after the step of first cutting the mask member 10 ( S520 ), preferably it may be performed before the first cutting step ( S520 ), and most preferably the first cutting It may be performed simultaneously with step S520. For example, the manufacturing apparatus allows the mask member 10 to pass through a set of rollers, but the rollers form fusion lines 115 , 135 , 185 , 215 at a specific position, and at a specific position of the skirt 200 . The mask member 10 may be cut along the outer edge 210 and the cutting line 11 . The bridge of the nose support piece 380 shown in FIG. 12 may be mounted on a portion of the fusion line 185 formed at a position corresponding to the contact portion 180 of the body pad 100 .

The step of primarily cutting the mask member 10 ( S520 ) may also include forming the opening 150 at a position corresponding to the body pad 100 . The window member 350 may be coupled to the opening 150 later. As shown in FIG. 12 depicting components for manufacturing the mask 1000 , an adhesive part 360 may be formed along the edge of the window member 350 , and the adhesive part 360 is formed through the opening 150 . As it is attached along the circumference of the window member 350 may be mounted. Therefore, the opening 150 has a size that can secure a slight distance from the fold line 19 in consideration of the thickness of the adhesive part 360, and the central portion 15 between the two fold lines 19 of the mask member 10. can be formed in

If necessary, the step of first cutting the mask member 10 ( S520 ) may include forming the cutouts 172 , 174 , and 176 at positions corresponding to the body pad 100 . The cutouts 172 , 174 , and 176 may be formed when the masks 1300 and 1400 according to the third and fourth embodiments are manufactured. As described above, each of the cutouts 172 , 174 , 176 may be advantageously formed with a length not exceeding 40 mm.

When the mask member 10 is transported in a form unrolled from a roll (not shown) and an opening 150 or a cutout 176 is formed in the mask member 10, the mask member 10 may be transported while being pulled. , the remaining portion of the mask member 10 may not provide sufficient strength required for transport due to the opening 150 or the cutout 176 formed in the central portion 15 of the mask member 10 .

In order to solve this problem, the step of transferring the mask member 10 ( S510 ) may include disposing the intermediate material 30 on one surface of the mask member 10 . For example, when the opening 150 is formed in the mask member 10, the mask member 10 is processed while being transported in the vertical direction. ) are disposed to overlap both sides of the opening 150 and may be transported together. The intermediate material 30 may constitute a part of the mask 1000 due to subsequent processing, and may serve to reinforce the side of the opening 150 during and after the manufacturing of the mask 1000 is completed.

As the intermediate material 30 reinforces both sides of the opening 150 in this way, even if the opening 150 occupies a significant portion of the area of the entire body pad 100, when the mask member 10 is pulled for transport, the intermediate material ( 30) can prevent the shape of the mask member 10 from being disturbed, thereby greatly reducing the defect rate in manufacturing the mask 1000 . In the example shown in FIG. 13 , the intermediate member 30 is disposed on the mask member 10 to which it is transferred, but the intermediate member 30 may be disposed under the mask member 10 . When the intermediate member 30 covers only the side of the opening 150 without covering the entire opening 150 , an increase in weight due to the addition of the intermediate member may be limited.

As another example, when the cutouts 172 , 174 , and 76 are formed in the mask member 10 , the mask member 10 is processed while being transported in the longitudinal direction, and the intermediate member 30 is disposed in the middle of the mask member 10 . ) is disposed overlapping to cover the cutouts (172, 174, 76) and can be transported together. The intermediate material 30 constitutes a part of the masks 1300 and 1400 due to subsequent processing and may serve to reinforce the side of the opening 150 during the manufacturing process of the masks 1300 and 1400 and after the manufacturing is completed. Therefore, it may be removed during the manufacturing process.

If necessary, the mask manufacturing method according to an embodiment of the present invention may include a step (S530) of coupling the wearing strap 300 to both sides of the mask member (12, 17). For example, as shown in FIG. 12 , both sides of the mask member 10 are cut along the outer edge 210 of the skirt part 200 in the step ( S520 ) of first cutting the mask member 10 . In this state, the wearing strap 300 may be coupled to the position of the connection parts 232 and 234 according to the design. Wearing strap 300 may be formed in a length that does not interfere with processing applied in a subsequent step. Of course, the wearing strap 300 has high elasticity even if it has a length that does not interfere with the processing of a subsequent step when the mask 1000 is manufactured. .

After the mask member 10 is primarily cut, a step (S540) of folding both sides 12 and 17 of the mask member 10 inward may be performed. In the process of bending both sides of the mask member 10 as described above, one side 12 and the other side 17 of the mask member 10 may be folded to overlap over the center portion 15 of the mask member 10, the folded side It can be folded so that the edge of 12 is spaced apart from the fold line 19" of the other side 17, and the edge of the folded other side 17 is spaced apart from the fold line 19' of the one side 12. That is, the mask member A fold line 19 is formed at a position where the outer edge 190 of the skirt part 200 cut and formed in the step of primarily cutting ( S520 ) contacts the fold line 19 or does not pass the fold line 19 . can be

When the wearing strap 300 is coupled to both sides 12 and 17 of the mask member 10, the wearing strap 300 coupled to one side 12 is an edge 210 and one side 12 of one side 12. Is disposed to overlap on one side 12 between the coupling lines 190 of the, and the wearing strap 300 coupled to the other side 17 is between the edge 210 of the other side 17 and the coupling line 190 of the other side 17 It may be arranged to overlap the other side (17) in the. That is, in the current stage, the coupling line 190 is not formed yet, but the wearing string 300 is processed to form the coupling line 190 on one side 12 and the other side 17 of the mask member 10 in a subsequent step. It can be prepared so as not to disturb it when it becomes available. To this end, the wearing string 300 may be prepared with a length that does not cross the coupling line 190 or the inner edge 220 in a state coupled to the connection parts 232 and 234, and the outer edge 210 and the coupling line 190 ) can be placed in the region between

In a state in which both sides 12 and 17 of the mask member 10 are folded inward, forming the coupling lines 190, 194, 195, 196 and/or the side fusion lines 197 on the mask member 10 (S550) ) can be performed. That is, the bonding lines 190 , 194 , 195 , 196 and the side fusion lines 197 are formed in the bent and overlapped portion of the mask member 10 , but the middle portion 15 of one side 12 of the mask member 10 . ) is overlapped and the other side 17 is not overlapped, and the coupling lines 190 and 194 are overlapped in the middle portion 15 of the other side 17 of the mask member 10 and are not overlapped with the one side 12 at positions that are not overlapped. , 195, 196) and the side fusion line 197 can be formed.

14 is a plan view exemplarily illustrating the step S550 of forming the coupling line 190 on the mask member 10 in the mask manufacturing method according to an embodiment of the present invention. In the step (S520) of first cutting the mask member 10, the outer edge 210 of the skirt part 200 and the part outside the cutting line 11 of the mask member 10 were cut and separated, and thus both sides ( In the mask member 10 in which 12 and 17 are folded inward, one side 12 and the other side 17 are both overlapped on the center portion 15 of the mask member 10, and the center portion of the mask member 10 ( 15) There may be a portion in which only one side 12 is overlapped, a portion in which only the other side 17 is overlapped, and a portion in which both the one side 12 and the other side 17 are not overlapped above the central portion 15 .

The bonding line 190 may be formed on the folded mask member 10 by fusion, sewing, or other methods. For example, one side 12 and the center portion 15 of the mask member 10 are fused along the coupling line 190 while the mask member 10, both sides of which is folded inward, passes through a welding roller, etc., and the mask member 10 ) of the other side 17 and the middle part 15 can be fused.

Of course, the step of forming the coupling line 190 on the mask member 10 ( S550 ) may also include the step of forming the fusion line at a required position. For example, the fusion line 135 for reinforcing the lower edge 130 of the body pad 100 may be formed in the fusion line forming step performed before or after the above-described primary cutting step (S520) or at the same time, It is possible to more effectively prevent mismatch between the lower edge 130 and the coupling line 190 by folding both sides of the mask member 10 inward and then forming the coupling line 190 together in the step (S550). Similarly, among the fusion lines 115 for reinforcing the upper edge 110 of the body pad 100 , the portion that is not coupled to the protrusion 280 of the skirt 200 is also before and after the above-described primary cutting step ( S520 ). Alternatively, it may be formed in the fusion line forming step performed at the same time, but it may be more advantageous to be formed together in the step ( S550 ) of forming the bonding line 190 .

It is preferable that the fusion lines 115 and 192 of the portion of the body pad 100 coupled to the protrusion 280 of the skirt 200 are formed together in the step S550 of forming the bonding line 190, the fusion line This is because (115, 192) serves to couple the close contact portion 180 and the protrusion portion 280, and the mask member 10 must be formed in a state in which both sides are folded.

The coupling line in the close contact portion 180 may be implemented in various forms, and three examples are shown in FIG. 14 . As shown in (a) of Figure 14, in some embodiments, the coupling line 190 may be continued only to a position corresponding to the upper end of the arch support portion (160). That is, only the fusion line 192 for coupling with the protrusion 280 is formed in the close contact portion 180 , and the coupling line for bending the skirt 200 may be omitted.

On the other hand, in some embodiments, similarly to FIG. 14B , the coupling line 194 in the close contact unit 180 may maintain the angle or curvature of the coupling line 190 in the upper portion of the arch support unit 160 . This has the effect of narrowing the upper end of the portion that forms the dome-type tent space in front of the user's nose and mouth of the body pad 100, so that the dome-type tent space (ie, the front part 140) protrudes further forward. can

In some embodiments, similarly to FIG. 14(c) , the coupling line 196 in the close contact unit 180 may extend vertically upward from the upper portion of the arch support unit 160 in the vertical direction. This allows the dome-type tent space by the body pad 100 to form a space of sufficient size in front of the user's nose and mouth, while the upper end is in close contact with the bridge of the nose support piece 380 over a larger length.

According to an embodiment of the present invention, the step (S550) of forming a coupling line 190 on the mask member 10 even in a state in which the wearing string 300 is coupled to both sides 12 and 17 of the mask member 10 can be performed. As depicted in (a) of FIG. 14 , the wearing strap 300 is disposed overlapping each of the one side 12 and the other side 17 of the mask member 10 , and is spaced apart from the coupling line 190 by a predetermined distance. can be placed. In a state in which the wearing strap 300 is disposed not to protrude and not exposed to the outside of the coupling line 190 in this way, the above-described coupling lines 190, 194, 195, 196, the side fusion lines 197 and other fusion lines 115, Processing to form 192 is not hampered by the wear strap 300 .

After or at the same time that the step (S550) of forming the coupling line 190 on the mask member 10 is performed, the step of secondary cutting the mask member 10 (S560) may be performed. Here, the mask member 10 may be cut along the shapes of the upper edge 110 , the outer edge 120 , and the lower edge 130 of the body pad 100 . When the center portion 15 of the mask member 10 is cut to form the outer edge 120 of the body pad 100 , one side 12 and the other side of the mask member 10 superimposed on the center portion 15 . 17 may be cut together to form the inner edge 220 of the skirt portion 200 .

14 and 15 , in a state where both sides of the mask member 10 are folded, the outer edge 210 of the skirt part 200 is disposed not to pass the outer edge 120 of the body pad 100 , so that the mask It is not affected by the secondary cutting of the member 10 . In addition, when the wearing string 300 is coupled, the wearing string 300 is provided with a length and arrangement that does not protrude beyond the outer edge 120 , so that the wearing string 300 is also affected by the secondary cutting of the mask member 10 . do not receive 15 (a), (b) and (c) show the mask 1000 obtained by cutting the mask member 10 shown in FIGS. 14 (a), (b) and (c).

When one or more of the wearing strap 300, the window member 350, and the bridge of the nose support piece 380 is not yet coupled, the mask manufacturing method according to an embodiment of the present invention is applied to the mask 1000 shown in FIG. The step of mounting one or more of the wearing strap 300 , the window member 350 and the bridge of the nose support piece 380 may be further included.

The mask 1000 manufactured according to an embodiment of the present invention may be packaged and distributed in a state in which the skirt part 200 is folded over the body pad 100 as shown in FIG. 15 . This provides an advantage that the filter member included in the mask 1000 can be maintained in a flat state without being bent while the mask 1000 occupies a very small area, thereby significantly reducing the cost of raw materials and packaging.

According to an embodiment of the present invention, processing processes such as cutting, fusion, and wearing strap mounting can be performed while the mask member 10 is transferred in one direction, so that it is possible to manufacture a mask with high productivity and high yield.

When the user wears the mask 1000 completed in this way, the user will spread the skirt part 200 and use the wearing strap 300 mounted on the connection parts 232 and 234 of the skirt part 200 over the ear. The wearing strap 300 applies tension to the skirt part 200 and the body pad 100, which causes the body pad 100 to be convexly bent/bent forward to form a dome-shaped space, and thus the mask ( 1000), it is possible to significantly reduce the area in which the inner surface contacts the user's nose and mouth. The position of the connection parts 232 and 234 to which the wearing strap 300 is coupled is selected to prevent the dome-shaped space formed by the body pad 100 from being crushed so that the mask 1000 can be maintained in close contact with the user's face. do.

In this structure, since the body pad 100 extends in the longitudinal direction, it is possible to form an opening 150 having a large area in the body pad 100, and the opening 150 allows both the user's nose and mouth to be identified from the outside. It can be formed in any size. Even if a window having a large area is formed in the body pad 100 , a filter having an equivalent area may be provided in the skirt part 200 , so that the original function of the mask for filtering external air can be faithfully performed.

Although the above has been described with reference to an embodiment of the present invention, those of ordinary skill in the art can variously change the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that modifications and variations are possible.
