Description

[Technical Field]

[0001] The present disclosure relates to a method for manufacturing a mask and a mask. [Background technology]

[0002] BACKGROUND ART In recent years, disposable masks have become known in which ear straps are attached to a mask body made of laminated nonwoven fabric or the like (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-2483 Summary of the Invention [Problem to be solved by the invention]

[0004] When multiple masks are packed in a bag with ear straps whose central portions can move freely relative to the mask body, it is possible that the ear straps of different masks may become tangled. This may make it difficult to remove the masks from the bag. Furthermore, ear straps that can move freely relative to the mask body are easier to grasp with fingers than the mask body. This means that when removing a mask from the bag, the ear straps may be grasped first before the mask body. This may result in the ear straps becoming detached from the mask body.

[0005] In one aspect, the present disclosure has been made in consideration of the above-described situation, and its purpose is to provide a technology that allows masks packed in a bag to be easily removed while preventing the ear straps from peeling off. [Means for solving the problem]

[0006] In order to solve the above problem, in the present invention, the central portions of the ear straps are placed on the mask body and remain stationary.

[0007] In detail, a method for manufacturing a mask according to one aspect of the present invention includes a first bonding step of bonding the ends of the ear loops to the mask body, and a resting step of overlapping and resting the central portions of the ear loops, the ends of which have been bonded to the mask body in the first bonding step, on the mask body.

[0008] Furthermore, in the method for manufacturing a mask according to the above aspect, the first bonding step may include positioning the ear hook portions so that they are convex outward in the width direction of the mask body and bonding the ends to the mask body, and the restoring step may include a folding step of folding the ear hook portions so that at least a portion of the portions of the ear hook portions that extend outward in the width direction of the mask body overlaps the mask body.

[0009] In addition, in the method for manufacturing a mask according to the above aspect, in the folding process, at least a part of the protruding portion of the ear loop portion may be folded back toward the mask body, and the folded back portion of the ear loop portion may be pressed toward the mask body to create a crease in the folded back portion.

[0010] Furthermore, in the method for manufacturing a mask according to the above aspect, in the folding process, the ear hook portion may be folded so that the ear hook portion overlaps the surface of the mask body on the side to which the end of the ear hook portion was adhered in the first bonding process.

[0011] In addition, in the mask manufacturing method according to the above aspect, the restoring process may include a second bonding process in which the ear loops, which are folded in the folding process and overlapped on the mask body, are bonded to the mask body with a predetermined adhesive strength.

[0012] In the mask manufacturing method according to the above aspect, in the second bonding step, a second end portion in the width direction of the mask body and the ear hook portion may be bonded with the predetermined bonding strength.

[0013] In addition, in the mask manufacturing method according to the above aspect, an adhesive region that can be adhered to the ear hook portion with the predetermined adhesive strength in the second adhesive step may be provided at the second end along the manufacturing flow direction.

[0014] In the method for manufacturing a mask according to the above aspect, a tape-shaped member is provided at the second end portion, In the second bonding step, the tape-shaped member and the ear hooking portion may be bonded to each other with the predetermined adhesive strength.

[0015] Furthermore, in the mask manufacturing method relating to the above-mentioned aspect, in the folding process, the ear hook portion is folded so as to overlap a rod extending along the manufacturing flow direction between the center of the width of the mask body and the second end portion, and in the second bonding process, the second end portion and the ear hook portion are bonded with the specified adhesive strength while the ear hook portion is overlapping the rod-shaped member.

[0016] In addition, in the mask manufacturing method relating to the above-mentioned one aspect, the adhesion between the ear hook portion and the mask body in the second adhesion process may be any one of thermal welding, ultrasonic welding, and adhesion via a hot melt adhesive.

[0017] Furthermore, a mask according to one aspect of the present invention comprises a mask body and ear loops, the ends of which are fixed to both ends of the mask body in the width direction so as to convex outward in the width direction, and the ear loops may have folds that can be folded back in the width direction so that at least a portion of the portion that protrudes outward in the width direction of the mask body overlaps with the mask body.

[0018] In the mask according to the above aspect, the fold may be foldable so that the ear loops overlap the surface of the mask body to which the end portions are fixed.

[0019] In the mask according to the above aspect, the mask body and the ear loops that are folded back at the folds and overlap the mask body may be bonded with a predetermined adhesive strength.

[0020] In the mask according to the above aspect, the adhesion may be performed between a second end portion in the width direction of the mask body and the ear hook portion.

[0027] [First embodiment] A mask and a method for manufacturing a mask according to a first embodiment of the present invention will be described below with reference to the drawings. Note that the configurations of the following embodiments are examples, and the present invention is not limited to the configurations of these embodiments.

[0028] 1 and 2 illustrate an outline of an external view of a mask 1 according to a first embodiment. FIG. 1 is an example of an external perspective view of the mask 1 as seen from the non-skin-facing side. FIG. 2 is an example of an external view of the mask 1 as seen from the skin-facing side. In this embodiment, the up-down direction of the mask 1 corresponds to the up-down direction of the wearer when wearing the mask.

[0029] As shown in FIGS. 1 and 2, the mask 1 includes a mask body 2, ear straps 3 and 4 (an example of the "ear loops" of the present disclosure), edge tapes 5 and 6 (an example of the "tape-like member" and "adhesive region" of the present disclosure), and a nose fitter 7. More specifically, the mask body 2 is formed by laminating several layers of breathable sheet material and is large enough to cover the wearer's mouth and nose. The ear straps 3 and 4 are made of a string-like elastic material. As shown in FIGS. 1 and 2, edge tapes 5 and 6 are attached to both ends of the width of the mask body 2 on the skin-facing and non-skin-facing sides. The edges of the ear straps 3 and 4 are thermally welded to the edge tapes 5 and 6 attached to the skin-facing side of the mask body 2, forming annular loops on both the left and right sides of the mask body 2. As shown in FIG. 2, the welding areas 15, 16 of the edge tapes 5, 6 to which the ends of the ear straps 3, 4 are heat-welded are designed to be wider than the other areas of the edge tapes 5, 6.

[0030] The string-like elastic material that makes up the ear straps 3, 4 may be formed, for example, from a woven band of rubber thread and cotton, a woven net of resin filaments, or an elastic nonwoven fabric. As shown in Figure 2, both ends of such string-like material are heat-sealed to welding regions 15, 16 of edge tapes 5, 6 on the skin-facing side of the mask body 2, respectively, to form loop-shaped ear straps 3, 4 on both sides of the mask body 2, with one end of the material as the starting point and the other end as the ending point.

[0031] The mask body 2 is composed of various sheets such as breathable nonwoven fabrics, and is a laminate of multiple sheets. The multiple sheets are heat-welded to each other by an embossing roll at heat-welding sections (9U, 9D, 9L, 9R) near the top, bottom, left, and right edges in FIG. 2. Note that ultrasonic welding may be used instead of heat welding. Alternatively, various joining techniques, such as sewing with sewing thread, bonding with hot-melt adhesive, heat sealing, etc., may be used.

[0032] The mask body 2 is folded along creases 8 extending in the width direction to form a pleated shape (see Figures 1 and 2). This pleated shape is maintained by edge tapes 5, 6 at the left and right ends that prevent the creases 8 from unfolding. Therefore, when the mask 1 is not worn, the mask body 2 can be flat and not bulky. On the other hand, when the mask 1 is worn, the creases 8 are unfolded by stretching the mask body 2 vertically. Therefore, as the pleats unfold, the mask body 2 assumes a dome-like three-dimensional shape that bulges toward the non-skin facing side. This creates a space between the mask body 2 and the wearer's mouth, allowing the wearer to breathe more easily.

[0033] The nose fitter 7 is a component fixed to the mask body 2 at the top of the mask body 2 with its longitudinal direction extending in the left-right direction of the mask body 2. The nose fitter 7 is fixed to the mask body 2 by being sandwiched between the sheet-like breathable materials that make up the mask body 2. Alternatively, the nose fitter 7 may be fixed to the surface of the mask body 2. The nose fitter 7 is made of a plastically deformable material that has enough strength to be deformed into an appropriate shape when pressed with the wearer's fingers, and maintains its shape even after the pressure is released. By providing such a nose fitter 7 at the top of the mask body 2 as shown in FIG. 1, the wearer can close the gap between their nose and the mask body 2.

[0034] Next, a method for manufacturing the mask 1 will be described. FIG. 3 illustrates an overview of a mask manufacturing apparatus 50 that manufactures the mask 1. As shown in FIG. 3, the mask manufacturing apparatus 50 includes a belt conveyor 51 that transports the mask body 2. The mask manufacturing apparatus 50 also includes a rod 52 that extends in the transport direction above (in FIG. 3) the mounting surface of the belt conveyor 51 on which the mask body 2 is placed. A gap of approximately the thickness of the mask 1 is provided between the mounting surface of the belt conveyor 51 and the rod 52. The rod 52 is also positioned away from the center of the mask body 2 toward both ends in the width direction.

[0035] The mask manufacturing apparatus 50 also includes a plate 53 on the side of the belt conveyor 51 in the transport direction. The plate 53 is provided parallel to the placement surface of the belt conveyor 51. The height at which the plate 53 is placed is slightly higher than the placement surface of the belt conveyor 51, and is a height at which the plate 53 can pass above the mask 1 placed on the placement surface of the belt conveyor 51 (in FIG. 3 ) when slid toward the belt conveyor 51.

[0036] The mask manufacturing apparatus 50 also includes a press tool 54. The press tool 54 is provided above the mounting surface of the belt conveyor 51 (in FIG. 3) and to the side of the conveyance direction. The press tool 54 has a rectangular parallelepiped shape that extends along the conveyance direction of the belt conveyor 51. A heater (not shown) is provided inside the press tool 54, and the surface of the press tool 54 that faces the mounting surface of the belt conveyor 51 can be heated. The plate 53 is provided with a hole 55 through which the press tool 54 can pass.

[0037] Also, in Figure 3, the plate 53 and the press tool 54 are shown only on one side of the conveying direction of the belt conveyor 51, but a similar plate 53 and press tool 54 are also provided on the other side of the conveying direction of the belt conveyor 51 (not shown).

[0038] Fig. 4 illustrates an outline of a flowchart for manufacturing and bagging masks 1 by the mask manufacturing apparatus 50 shown in Fig. 3. In the following description, unless otherwise specified, welding refers to thermal welding.

[0039] (S1) In step S1, the ends of the ear straps 3 and 4 are welded to the mask body 2. More specifically, as shown in FIG. 2, the ends of the ear straps 3 and 4 are welded from the skin-facing side to welding regions 15 and 16 of edge tapes 5 and 6 provided on the skin-facing side of the mask body 2. As mentioned above, the welding regions 15 and 16 to which the ends of the ear straps 3 and 4 are welded are wide. This makes it easy to weld the ends of the ear straps 3 and 4 to the edge tapes 5 and 6. This prevents poor welding.

[0040] Furthermore, when the ends of the ear straps 3, 4 are welded to the welding regions 15, 16 of the edge tapes 5, 6, the centers of the ear straps 3, 4 are positioned so that they are on the outside of the mask body 2. Therefore, the ear straps 3, 4 welded to the edge tapes 5, 6 protrude from the outside of the mask body 2 as shown in FIG. 2. The mask bodies 2 with the welded ear straps 3, 4 are then arranged on the mounting surface of the belt conveyor 51 of the mask manufacturing apparatus 50 as shown in FIG. 3. The mask bodies 2 are arranged so that they are sandwiched between the mounting surface and the rod 52. The mask bodies 2 are arranged on the mounting surface of the belt conveyor 51 so that the nose fitter 7 faces in the opposite direction to the conveying direction. Step S1 is an example of the "first bonding step" of the present disclosure.

[0041] (S2) In step S2, the central portions of the ear straps 3, 4, which were welded to the mask body 2 in step S1 and are protruding from the mask body 2, are folded back toward the inside of the mask body 2. Figure 5 illustrates an example of the operation of the mask manufacturing apparatus 50 to fold back the ear straps 3 toward the inside of the mask body 2. Note that while Figure 5 shows an example of folding back the ear straps 3, the ear straps 4 can also be folded back in the same way.

[0042] As shown in FIG. 5, the plate 53 of the mask manufacturing device 50 moves toward the mask body 2 placed on the placement surface of the belt conveyor 51. The plate 53 then comes into contact with the ear straps 3 that are sticking out from the mask body 2. The plate 53 then pushes the ear straps 3 toward the center of the mask body 2 until the holes 55 overlap the widthwise ends of the mask body 2, and then stops moving. As the plate 53 moves in this manner, the center portions of the ear straps 3 overlap the mask body 2. The center portions of the ear straps 3 also overlap the rods 52. Step S2 is an example of the "folding process" of the present disclosure.

[0043] (S3) In step S3, the ear straps 3, 4 that were placed in the center of the mask body 2 in step S2 are temporarily welded to the mask body 2. Temporarily welding means that the peel strength of the ear straps 3 welded to the mask body 2 is such that, for example, when the ear straps 3 temporarily welded to the mask body 2 are pinched with fingers, they peel off from the mask body 2. Alternatively, hot melt adhesive or ultrasonic welding may be used instead of welding.

[0044] Figure 6 illustrates an example of the operation of the mask manufacturing device 50 for temporarily welding the center of the ear strap 3 to the mask body 2. Note that Figure 6 shows an example of temporarily welding the ear strap 3 to the mask body 2, but temporarily welding the ear strap 4 to the mask body 2 can also be performed in the same way.

[0045] As shown in FIG. 6, the pressing tool 54 moves toward the mask body 2. Then, the pressing tool 54 passes through the hole 55 provided in the plate 53 and presses the mask body 2. The press tool 54 then contacts the overlapping ear straps 3. The press tool 54 then presses the ear straps 3 against the mask body 2 for a predetermined period of time.

[0046] Here, the pressing tool 54 that contacts the ear strap 3 is heated by a heater. The pressing tool 54 then contacts and presses the ear strap 3 that overlaps the edge tape 5. This causes the heat from the heater to be transferred to the ear strap 3, and then to the contact area between the ear strap 3 and the edge tape 5. This causes the nonwoven fabric fibers of the ear strap 3 and the edge tape 5 that are present at this contact area to melt. After a predetermined time has passed, the pressing tool 54 separates from the mask body 2. This causes the nonwoven fabric fibers of the ear strap 3 and the edge tape 5 that are present at this contact area and melted by the heat to solidify in a molten state. In this way, the ear strap 3 and the mask body 2 (edge ​​tape 5) are temporarily welded together.

[0047] In order to achieve a desired strength of temporary welding between the ear straps 3 and the mask body 2, the predetermined time for which the pressing tool 54 presses the ear straps 3 against the mask body 2 may be adjusted. Alternatively, the temperature of the heater that heats the pressing tool 54 may be adjusted.

[0048] Alternatively, when the ear straps 3 and the mask body 2 are temporarily welded together using a hot melt adhesive as an alternative to thermal welding, the application area or amount of the hot melt adhesive is adjusted to achieve the desired strength of the temporary welding between the ear straps 3 and the mask body 2.

[0049] Furthermore, before the ear straps 3 are temporarily welded to the mask body 2, creases may be formed in the folded portions of the ear straps 3 that are folded back toward the center of the mask body 2 so that the ear straps 3 can easily overlap the mask body 2. In this case, the ear straps 3 can be kept stationary even if the strength of the temporary welding between the ear straps 3 and the mask body 2 is reduced.

[0050] FIG. 7 shows an example of the mask 1 in a state where the ear straps 3, 4 and the mask body 2 (edge ​​tapes 5, 6) have been temporarily welded together by performing step S3. The area where the ear straps 3, 4 and the mask body 2 are temporarily welded is shown as a temporarily welded area 17 with diagonal lines. Although the temporarily welded area 17 is shown as a diagonal line in FIG. 7, the diagonal lines simply indicate the area, and the temporarily welded area 17 does not differ in shape from the other areas of the ear straps 3, 4. In FIG. 7, the temporarily welded area 17 refers to the back surface of the ear straps 3, 4.

[0051] As shown in FIG. 7, the pre-welded areas 17 are located near the base ends 18 of the ear straps 3, 4 (welded to the edge tapes 5, 6 in step S1) and overlap with the edge tapes 5, 6. In this way, in the mask 1, the areas near the base ends 18 of the ear straps 3, 4 are pre-welded to the mask body 2 (edge ​​tapes 5, 6). On the other hand, the central portions of the ear straps 3, 4 that overlap with the central portion of the mask body 2 are not pre-welded to the mask body 2. Step S3 is an example of the "second bonding step" and "resting step" of the present disclosure.

[0052] (S4) In step S4, a plurality of masks 1 are stacked as shown in Fig. 7. Then, the stacked masks 1 are packed in a bag (or a box, etc.).

[0053] [Actions and Effects] According to the manufacturing method of the mask 1 described above, the mask 1 is packed in a bag with the ear straps 3, 4 overlapping the center of the mask body 2 and the ends of the ear straps 3, 4 temporarily welded to the mask body 2 (edge ​​tapes 5, 6) (see FIG. 7). This prevents the ear straps 3, 4 from becoming entangled with the ear straps of other masks when the mask 1 is packed. This makes it easy to remove the mask 1 packed in the bag.

[0054] Furthermore, according to the manufacturing method of the mask 1 described above, the mask 1 is packaged in a bag with the ear straps 3, 4 overlapping the mask main body 2 and temporarily welded to the mask main body 2 (edge ​​tapes 5, 6). Therefore, when the recipient takes out the mask 1 packaged in the bag, they are prevented from pinching the ear straps 3, 4, and instead take out the mask main body 2 from the bag by pinching it with their fingers. This prevents the ear straps 3, 4 from peeling off from the mask main body 2 when taking it out.

[0055] Furthermore, according to the above-described manufacturing method of the mask 1, the temporary welding areas 17 near the base ends 18 of the ear straps 3, 4 are temporarily welded to the mask body 2 (see FIG. 7). Here, the base ends 18 of the ear straps 3, 4 are welded to the edge tapes 5, 6 in step S1, so positional change is suppressed. Therefore, the temporary welding of the temporary welding areas 17 of the ear straps 3, 4 to the mask body 2 (edge ​​tapes 5, 6) eliminates the need for a process to monitor or suppress positional change of the ear straps 3, 4. This reduces the number of manufacturing steps.

[0056] Incidentally, when the center of the mask body 2 and the ear straps 3, 4 are temporarily welded, peeling marks may remain in the center of the mask body 2 when the ear straps 3, 4 are peeled off from the mask body 2. In such cases, the peeling marks may come into contact with the skin of the wearer wearing the mask 1, which may cause discomfort to the wearer.

[0057] On the other hand, according to the manufacturing method of the mask 1 described above, the temporarily welded regions 17 near the base ends 18 of the ear straps 3 and 4 are temporarily welded to the edge tapes 5 and 6 located at the widthwise ends of the mask body 2. Therefore, even if peeling marks from the ear straps 3 and 4 remain on the edge tapes 5 and 6, the peeling marks will be located at the widthwise ends of the mask body 2. At these widthwise ends of the mask body 2, the ear straps 3 and 4 are folded back toward the center of the mask body 2. In other words, because the widthwise ends of the mask body 2 have convex portions that face the wearer's skin, the peeling marks from the peeling of the temporarily welded ear straps 3 and 4 are prevented from coming into contact with the wearer's skin. This prevents the wearer from feeling uncomfortable due to the peeling marks.

[0058] Furthermore, the mask 1 as described above ensures that the surfaces of the edge tapes 5 and 6 are flat. This prevents the contact between the edge tapes 5 and 6 and the ear straps 3 and 4 from becoming unstable. This prevents the temporary welding from becoming defective.

[0059] Furthermore, according to the above-described manufacturing method of the mask 1, in step S1, the ear straps 3, 4 are placed on the side of the mask body 2 (skin side) on which the edge tapes 5, 6 to which the ear straps 3, 4 are welded are provided (step S2). This reduces the resistance to folding the ear straps 3, 4 compared to placing the ear straps 3, 4 on the side of the mask body 2 opposite the side on which the edge tapes 5, 6 to which the ear straps 3, 4 are welded are provided (non-skin side). This makes the process of placing the ear straps 3, 4 on the center of the mask body 2 (step S2) easier. This reduces the occurrence of manufacturing defects in the mask 1.

[0060] Furthermore, according to the above-described manufacturing method of the mask 1, when the ear straps 3, 4 are placed over the center of the mask body 2 in step S2, the center of the ear straps 3, 4 overlaps the rod 52. Then, with the center of the ear straps 3, 4 overlapping the rod 52, the temporary welding regions 17 of the ear straps 3, 4 are temporarily welded to the mask body 2 (step S3). This prevents the entire ear straps 3, 4 from coming into close contact with the mask body 2. This makes it easier for the wearer to pinch the center of the ear straps 3, 4 to wear the mask 1 after it has been removed from the bag. This improves convenience for the wearer.

[0061] [Second embodiment] FIG. 8 illustrates an outline of a mask 1A according to the second embodiment. The mask 1A according to the second embodiment has the same components as the mask 1 according to the first embodiment. As with the mask 1, the base ends 18A of the ear straps 3A and 4A are first welded to the welding regions 15A and 16A of the edge tapes 5A and 6A of the mask body 2A, respectively. However, when welding the base ends 18A of the ear straps 3A and 4A to the welding regions 15A and 16A, the entire ear straps 3A and 4A are positioned so that they overlap the mask body 2A, as shown in FIG. 8 (an example of the "first bonding step" of the present disclosure). Then, the temporary welding regions 17A near the base ends 18A of the ear straps 3A and 4A are temporarily welded to the mask body 2A (an example of the "resting step" of the present disclosure). Then, multiple such masks 1A are stacked and packed into a bag. This manufacturing method of the mask 1A can also achieve the same effects as the first embodiment.

[0062] <Other variations> In the mask manufacturing process of the first embodiment, the ear straps 3, 4 are temporarily welded by heating them while pressing them against the edge tapes 5, 6 (step S3). However, it is also possible to simply crease the folded portions of the ear straps 3, 4 by pressing them without heating them. This type of mask can achieve the same effect as the mask 1. Furthermore, although all of the ear straps 3, 4 protruding from the mask body 2 are folded back toward the center of the mask body 2 (step S2), it is also possible to fold back a portion of the ear straps 3, 4 protruding from the mask body 2 toward the center of the mask body 2. Furthermore, the ear straps 3, 4 may be temporarily welded by overlapping them with the non-skin-facing side of the mask body 2. Furthermore, the edge tapes 5, 6 may not be provided. Furthermore, the ear straps 3, 4 may be temporarily welded to the mask body 2 at the center in the width direction rather than at the width direction ends. Furthermore, the mask manufacturing apparatus 50 does not necessarily require the use of a rod 52.

[0063] The embodiments and modifications disclosed above can be combined with each other. [Explanation of symbols]
