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

1 and 2 exemplify outlines of external views of a mask 1 according to the first embodiment. FIG. 1 is an example of an external perspective view of the mask 1 viewed from the non-skin side. FIG. 2 is an example of an external view of the mask 1 viewed from the skin surface side. In addition, in this embodiment, the vertical direction of the mask 1 is the direction corresponding to the vertical direction of the wearer in the wearing state.

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 hooking portion” of the present disclosure), edge tapes 5 and 6 (“tape-shaped members” of the present disclosure). ” and “adhesion region”), and a nose fitter 7 . More specifically, the mask main body 2 is formed by laminating several layers of sheet-like breathable materials, and has a size capable of covering the mouth and nose of the wearer. Moreover, 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 mask body 2 in the width direction on the skin side and the non-skin side. Then, the edge tapes 5 and 6 attached to the mask main body 2 on the skin side and the respective ends of the ear straps 3 and 4 are thermally welded, so that the ear straps 3 and 4 are attached to both left and right sides of the mask main body 2. form an annular ring in each. As shown in FIG. 2, the welding regions 15 and 16 of the edge tapes 5 and 6 to which the ends of the ear straps 3 and 4 are thermally welded are designed to be wider than the other regions of the edge tapes 5 and 6. It is

The string-like stretchable material constituting the ear straps 3 and 4 is formed of, for example, a mixed woven band of rubber thread and cotton, a mixed knitted net of resin filaments, or a stretchable nonwoven fabric. Both ends of such a string-like material are thermally welded to the welding regions 15 and 16 of the edge tapes 5 and 6 on the left and right sides of the skin surface of the mask body 2, respectively, as shown in FIG. Loop-shaped ear straps 3 and 4 are formed on both the left and right sides of the mask body 2, with one end of the material being the starting point and the other end of the material being the ending point.

The mask body 2 is composed of various sheets such as nonwoven fabric having air permeability, and is a laminate of a plurality of sheets. Then, the plurality of sheets are heat-sealed to each other by embossing rolls at the heat-sealing portions (9U, 9D, 9L, 9R) near the top, bottom, left, and right edges in FIG. Ultrasonic welding may be used as an alternative to thermal welding. Alternatively, for example, stitching with sewing thread or the like, adhesion with hot melt adhesive or the like, heat sealing, or other various bonding techniques can be applied.

The mask body 2 forms a pleated shape by being folded at folds 8 extending in the width direction (see FIGS. 1 and 2). Further, such a pleated shape is maintained by preventing the unfolding of the folds 8 by the edge tapes 5 and 6 at the ends on both the left and right sides. Therefore, when the mask 1 is not worn, the mask body 2 can be flat and not bulky. On the other hand, when wearing the mask 1, the mask body 2 is stretched in the vertical direction so that the creases 8 are unfolded. Therefore, the mask main body 2 has a three-dimensional dome shape that swells toward the non-skin surface side by widening the pleats. Thereby, a space is formed between the mask main body 2 and the wearer's mouth, and the wearer can breathe easily.

The nose fitter 7 is a member fixed to the mask body 2 in the upper part of the mask body 2 with its longitudinal direction extending in the lateral direction of the mask body 2 . The nose fitter 7 is fixed to the mask body 2 in a state of being sandwiched between sheet-like breathable materials forming 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 by being pressed by the wearer's fingers, and that maintains its shape even when the pressure is released. By providing such a nose fitter 7 at the upper part of the mask body 2 as shown in FIG.

Next, a method for manufacturing the mask 1 will be described. FIG. 3 illustrates an outline of a mask manufacturing apparatus 50 that manufactures the mask 1. As shown in FIG. As shown in FIG. 3, the mask manufacturing apparatus 50 includes a belt conveyor 51 that conveys the mask body 2. As shown in FIG. The mask manufacturing apparatus 50 also includes a rod 52 extending in the conveying direction above the mounting surface (in FIG. 3) of the belt conveyor 51 on which the mask body 2 is mounted. A gap approximately equal to the thickness of the mask 1 is provided between the mounting surface of the belt conveyor 51 and the bar 52 . Further, the rods 52 are arranged at positions closer to both ends in the width direction from the central portion of the mask body 2 .

The mask manufacturing apparatus 50 also includes a plate 53 on the side of the belt conveyor 51 in the conveying direction. The plate 53 is provided parallel to the mounting surface of the belt conveyor 51 . The height at which the plate 53 is arranged is slightly higher than the mounting surface of the belt conveyor 51, and when the plate 53 is slid in the direction of the belt conveyor 51, it is mounted on the mounting surface of the belt conveyor 51. It is a height that allows it to pass above the mask 1 (in FIG. 3).

The mask manufacturing apparatus 50 also includes a press tool 54 . The pressing device 54 is provided above the mounting surface of the belt conveyor 51 (in FIG. 3) and laterally with respect to the conveying direction. Also, the shape of the press tool 54 is a rectangular parallelepiped extending along the conveying direction of the belt conveyor 51 . Further, a heater (not shown) is provided inside the press tool 54 so that the surface of the press tool 54 facing 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.

3, the plate 53 and the pressing device 54 are shown only on one side of the belt conveyor 51 with respect to the conveying direction, but similar plates 53 and press tools 54 are also shown on the other side of the belt conveyor 51 with respect to the conveying direction. A press device 54 is provided (not shown).

FIG. 4 illustrates an outline of a flow chart for manufacturing and bagging the mask 1 by the mask manufacturing apparatus 50 as shown in FIG. In the following description, welding refers to heat welding unless otherwise specified.

(S1)
In step S1, the ends of the ear straps 3 and 4 are welded to the mask body 2. As shown in FIG. More specifically, as shown in FIG. 2, the ends of the ear straps 3 and 4 are welded from the skin side to the welding regions 15 and 16 of the edge tapes 5 and 6 provided on the skin side of the mask body 2. Let The welding regions 15 and 16 where the ends of the ear straps 3 and 4 are welded are wide as described above. Therefore, it becomes easy to weld the ends of the ear straps 3 and 4 to the edge tapes 5 and 6 . Therefore, poor welding is suppressed.

In addition, when the ends of the ear straps 3 and 4 are welded to the welding regions 15 and 16 of the edge tapes 5 and 6, the central portions of the ear straps 3 and 4 are placed outside the mask body 2.例文帳に追加Therefore, the ear straps 3, 4 welded to the edge tapes 5, 6 protrude outside the mask body 2 as shown in FIG. Then, the mask body 2 to which the ear straps 3 and 4 are welded is arranged on the mounting surface of the belt conveyor 51 of the mask manufacturing apparatus 50 as shown in FIG. Note that the mask body 2 is arranged so as to be sandwiched between the placement surface and the rod 52 . Also, the mask bodies 2 are arranged on the mounting surface of the belt conveyor 51 so that the nose fitter 7 faces the direction opposite to the conveying direction. Note that step S1 is an example of the "first bonding step" of the present disclosure.

(S2)
In step S2, the center portions of the ear straps 3 and 4, which are welded to the mask body 2 in step S1 and protrude from the mask body 2, are folded back toward the inside of the mask body 2. As shown in FIG. FIG. 5 illustrates an outline of an operation example of the mask manufacturing apparatus 50 that folds the ear straps 3 toward the inside of the mask body 2 . Although FIG. 5 shows an example in which the ear straps 3 are folded back, the folding of the ear straps 4 is also executed in the same manner.

As shown in FIG. 5, the plate 53 of the mask manufacturing apparatus 50 moves toward the mask body 2 placed on the placement surface of the belt conveyor 51 . Then, the plate 53 comes into contact with the ear straps 3 protruding outside the mask body 2 . The plate 53 moves until the hole 55 overlaps the end of the mask body 2 in the width direction while pushing the ear straps 3 in contact with it toward the center of the mask body 2, and then stops moving. By moving the plate 53 in this manner, the central portion of the ear strap 3 overlaps the mask body 2 . Also, the central portion of the ear strap 3 is overlaid on the bar 52 . Note that step S2 is an example of the "folding process" of the present disclosure.

(S3)
In step S3, the ear straps 3 and 4 superimposed on the central portion of the mask body 2 in step S2 are temporarily welded to the mask body 2. As shown in FIG. Temporary welding means that the peel strength of the ear straps 3 welded to the mask main body 2 is such that the ear straps 3 temporarily welded to the mask main body 2 are separated from the mask main body 2 when pinched by fingers. is the intensity of As an alternative to welding, hot-melt adhesive may be used, or ultrasonic welding may be used.

FIG. 6 illustrates an outline of an operation example of the mask manufacturing apparatus 50 for temporarily welding the central portion of the ear strap 3 to the mask body 2 . Although FIG. 6 shows an example in which the ear straps 3 are temporarily welded to the mask body 2, the temporary welding of the ear straps 4 to the mask body 2 is also performed in the same manner.

As shown in FIG. 6, the press tool 54 moves toward the mask body 2 . Then, the press tool 54 penetrates the hole 55 provided in the plate 53 as it is, and presses the mask main body 2 .
contacts the ear strap 3 overlapping with the . Then, the pressing device 54 presses the ear straps 3 against the mask body 2 for a predetermined time.

Here, the pressing device 54 that contacts the ear straps 3 is heated by a heater. Then, the pressing device 54 contacts and presses the ear cord 3 overlapping the edge tape 5 . Therefore, the heat of the heater is transferred to the ear string 3, and the heat is transferred to the contact portion between the ear string 3 and the edge tape 5. - 特許庁Therefore, the fibers of the non-woven fabric of the ear cord 3 and the portion of the edge tape 5 which are present in the contact portion are melted. After a predetermined period of time has elapsed, the pressing device 54 is separated from the mask body 2. As shown in FIG. Therefore, the fibers of the nonwoven fabric of the selvage cord 3 and the portion of the edge tape 5 that are present in the contact portion and are melted by heat are solidified in a melted state. In this manner, the ear string 3 and the mask body 2 (edge tape 5) are temporarily welded.

It should be noted that the predetermined time during which the pressing device 54 presses the ear straps 3 against the mask body 2 may be adjusted in order to set the strength of the temporary welding between the ear straps 3 and the mask body 2 to a desired strength. Alternatively, the temperature of the heater that heats the press tool 54 may be adjusted.

Alternatively, when temporary welding between the ear straps 3 and the mask body 2 is realized by a hot-melt adhesive as an alternative to heat welding, the strength of the temporary welding between the ear straps 3 and the mask body 2 is set to a desired strength. The application area or application amount of the hot melt adhesive is adjusted.

In addition, before the ear straps 3 and the mask body 2 are temporarily welded together, the folds of the ear straps 3 that are folded back toward the center of the mask body 2 are folded so that the ear straps 3 easily overlap the mask body 2 . good too. In such a case, the ear straps 3 can be kept still even if the strength of the temporary welding between the ear straps 3 and the mask body 2 is reduced.

FIG. 7 illustrates an outline of the mask 1 in a state in which the ear straps 3 and 4 and the mask body 2 (edge tapes 5 and 6) are temporarily welded by performing the process of step S3. The area where the ear straps 3 and 4 and the mask body 2 are temporarily welded is indicated by diagonal lines as a temporary weld area 17 . In FIG. 7, the temporarily welded area 17 is shown as a hatched portion, but the hatched lines simply indicate the area, and the temporarily welded area 17 does not differ from the other areas of the ear straps 3 and 4 in form. do not have. Also, the temporary welding region 17 indicates the back surface portions of the ear straps 3 and 4 in FIG.

As shown in FIG. 7, the temporarily welded region 17 is a portion in the vicinity of the base ends 18 of the ear straps 3 and 4 (welded to the edge tapes 5 and 6 in step S1) and overlapping the edge tapes 5 and 6. will be located in In this way, in the mask 1, the vicinity of the base ends 18 of the ear straps 3 and 4 are temporarily welded to the mask main body 2 (edge tapes 5 and 6). On the other hand, the central portions of the ear straps 3 and 4 that overlap the central portion of the mask body 2 are not temporarily welded to the mask body 2 . Note that step S3 is an example of the "second bonding step" and the "resting step" of the present disclosure.

(S4)
In step S4, a plurality of masks 1 as shown in FIG. 7 are laminated. Then, a plurality of stacked masks 1 are packed in a bag (a box or the like may be used).

[Action/effect]
According to the method of manufacturing the mask 1 as described above, the ear straps 3 and 4 overlap the central portion of the mask main body 2, and the ends of the ear straps 3 and 4 are attached to the mask main body 2 (edge tapes 5 and 6). is temporarily welded (see FIG. 7), and the mask 1 is packed in a bag. Therefore, when the mask 1 is packed, the ear straps 3 and 4 are prevented from being entangled with the ear straps of other masks. Therefore, it is possible to easily take out the mask 1 packed in the bag.

Further, according to the manufacturing method of the mask 1 as described above, the ear straps 3 and 4 are overlapped with the mask main body 2, and the ear straps 3 and 4 are temporarily welded to the mask main body 2 (edge tapes 5 and 6). The mask 1 is packed in a bag in a folded state. Therefore, when the implanted person takes out the mask 1 packed in the bag, the user is prevented from picking up the ear straps 3 and 4, and picks up the mask main body 2 with fingers to take it out of the bag. Therefore, peeling of the ear straps 3 and 4 from the mask main body 2 during removal is suppressed.

Further, according to the manufacturing method of the mask 1 as described above, the temporary welding regions 17 near the base ends 18 of the ear straps 3 and 4 are temporarily welded to the mask main body 2 (see FIG. 7). Here, since the base ends 18 of the ear straps 3 and 4 are welded to the edge tapes 5 and 6 in step S1, positional changes are suppressed. Therefore, it is possible to omit the step of monitoring or suppressing changes in the positions of the ear straps 3 and 4 for the temporary welding of the temporary welding regions 17 of the ear straps 3 and 4 and the mask body 2 (edge tapes 5 and 6). can be done. Therefore, a reduction in manufacturing man-hours is realized.

By the way, when the central portion of the mask body 2 and the ear straps 3 and 4 are temporarily welded together, it is conceivable that when the ear straps 3 and 4 are peeled off from the mask main body 2, peeling marks may remain in the central portion of the mask main body 2. be done. In such a case, the skin of the wearer wearing the mask 1 is in contact with the peeling marks. Therefore, the wearer may feel discomfort.

On the other hand, according to the manufacturing method of the mask 1 as described above, the temporary welding regions 17 near the base ends 18 of the ear straps 3 and 4 and the edge tapes 5 and 6 positioned at the ends in the width direction of the mask body 2 is temporarily welded. Therefore, even if the peeling traces of the ear straps 3 and 4 remain on the edge tapes 5 and 6, the peeling traces are located at the ends of the mask body 2 in the width direction. At the ends of the mask body 2 in the width direction, the ear straps 3 and 4 are folded toward the center of the mask body 2 . That is, since there is a convex portion on the wearer's skin side at the end of the mask body 2 in the width direction, the peeling marks of the temporary welding of the ear straps 3 and 4 come into contact with the wearer's skin. is suppressed. Therefore, it is possible to prevent the wearer from feeling discomfort due to the peeling mark.

Further, according to the mask 1 as described above, the flatness of the surfaces of the edge tapes 5 and 6 is ensured. Therefore, the contact between the edge tapes 5, 6 and the ear straps 3, 4 is prevented from becoming unstable. Therefore, it is suppressed that the temporary welding becomes defective.

According to the method of manufacturing the mask 1 as described above, the edge tapes 5 and 6 to which the ear straps 3 and 4 are welded in step S1 are provided on the side of the mask body 2 (skin side). Strings 3 and 4 are overlapped (step S2). Therefore, compared to the case where the ear straps 3 and 4 are superimposed on the surface (non-skin side) of the mask body 2 opposite to the side on which the edge tapes 5 and 6 to which the ear straps 3 and 4 are welded are provided. , the resistance for folding the ear straps 3 and 4 can be reduced. Therefore, the work process (step S2) of overlapping the ear straps 3 and 4 on the central portion of the mask body 2 is facilitated. Therefore, the occurrence of manufacturing defects in the mask 1 is suppressed.

Further, according to the manufacturing method of the mask 1 as described above, when the ear straps 3 and 4 are superimposed on the central portion of the mask main body 2 in step S2, the central portions of the ear straps 3 and 4 are attached to the bar 52. will overlap. Then, the temporarily welded regions 17 of the ear straps 3 and 4 are temporarily welded to the mask main body 2 while the center portions of the ear straps 3 and 4 overlap the bar 52 (step S3). Therefore, the entire ear straps 3 and 4 are prevented from coming into close contact with the mask body 2 . Therefore, it becomes easy for the wearer to pinch the central portions of the ear straps 3 and 4 in order to put on the mask 1 that has been taken out of the bag. Therefore, convenience for the wearer is improved.

[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 parts as the mask 1 according to the first embodiment. In manufacturing the mask 1A, similarly to the mask 1, first, the base ends 18A of the ear straps 3A and 4A are welded to the welding regions 15A and 16A of the edge tapes 5A and 6A of the mask body 2A. However, when the base ends 18A of the ear straps 3A and 4A are welded to the welding regions 15A and 16A, the entire ear straps 3A and 4A are arranged so as to overlap the mask body 2A as shown in FIG. (an example of the "first bonding step"). After that, the temporary welding regions 17A in the vicinity of the base ends 18A of the ear straps 3A and 4A are temporarily welded to the mask main body 2A (an example of the "static step" of the present disclosure). Then, a plurality of such masks 1A are stacked and packed in a bag. The same effects as those of the first embodiment can be obtained by such a method of manufacturing the mask 1A.

<Other Modifications>
In the manufacturing process of the mask in the first embodiment, the ear straps 3 and 4 are heated while being pressed against the edge tapes 5 and 6 to achieve temporary welding (step S3). It is also possible to simply crease the folded portions of the ear straps 3 and 4. Even with such a mask, the same effect as the mask 1 can be obtained. In addition, all of the ear straps 3 and 4 protruding from the mask body 2 are folded toward the center of the mask body 2 (step S2). may be folded back toward the center of the Moreover, the ear straps 3 and 4 may be overlapped and temporarily welded to the mask main body 2 on the non-skin surface side. Also, the edge tapes 5 and 6 may not be provided. Further, the temporary welding between the ear straps 3 and 4 and the mask body 2 may be performed not at the ends in the width direction but at the central portion in the width direction. Moreover, the bar 52 may not be arranged in the mask manufacturing apparatus 50 .

The embodiments and modifications disclosed above can be combined.
