Japanese Patent No. 3413585

  By the way, the present inventor has been researching to make it possible to adjust the length of the tightening strap even for an inexpensive disposable mask, but the adjustment mechanism as described above applied to other masks is applied to the disposable mask. Then, there exists a problem that manufacturing cost will rise and it will become expensive to sell as a disposable mask. Therefore, an object of the present invention is to provide a disposable mask capable of reducing the manufacturing cost by adopting a simple structure and capable of adjusting the length of the lace according to the size of the wearer.

  The present invention (1) includes a cover that can cover at least the mouth of the wearer, and a pair of fastening strings that are joined to the upper and lower sides of the right and left edges of the cover, respectively, and hung on the ear of the wearer. In the disposable mask provided, at least one of the joints in the upper and lower sides is formed by wave-sewing the fastening strap to the cover part.

  The present invention (2) includes a cover that can cover at least the mouth of the wearer, and a pair of fastening strings that are joined to the left and right of the upper and lower edges of the cover, respectively, and are hung on the back of the wearer. In addition, in the disposable mask, at least one of the joints on the left and right sides is formed by wave-sewing the fastening strap to the cover portion.

  Invention (3) is the disposable mask of the invention (1) or (2), wherein the cover is made of a nonwoven fabric.

  According to the present invention, as a method for adjusting the length of the tightening string according to the size of the wearer, since a very simple structure in which the tightening string is wave-sewn on the covering portion is adopted, it is possible to reduce the manufacturing cost in the disposable mask. There is an effect.

  First, as shown in FIG. 1, a disposable mask 10 according to the first best mode has a mask main body 11 capable of covering at least a mouthpiece of a wearer, and a pair of ear hooks 12 attached to both right and left ends. Yes.

  Here, as shown in FIG. 2, the mask main body 10 is a surface member 11a made of a heat-weldable nonwoven fabric, and a heat-weldable nonwoven fabric that is the same as or different from the surface material 11a, and a lining member that hits the mouth when worn. It is comprised from the laminated body of 11b. Then, as shown in FIG. 2, the outer surface member 11a and the lining member 11b are folded back stepwise in the vertical direction, and correspond to the opposite end edge portions corresponding to the upper and lower long side portions and the left and right short side portions. It is heat-sealed and fixed at the four sides of the opposing edge. Here, the steps in the vertical direction function so as to ensure stretchability for covering the part, considering that the distance from the nose to the chin varies depending on the wearer. Further, the heat-sealed portions A and B in the upper and lower longitudinal side portions are heat-sealed in a state where both the outer member 11a and the backing member 11b are folded at the end portions, that is, in a four-layer state. Further, the folded portion C in the upper longitudinal side portion incorporates a nose bridge 11c configured to be foldable so that a gap between the mask and the mouth is hardly opened along the wearer's skeleton. In addition, as a raw material of the heat-welding nonwoven fabric used for the surface member 11a and the lining member 11b, it is although it does not specifically limit, For example, the nonwoven fabric manufactured by methods, such as a spun bond, a spun lace, a thermal bond, and a melt blown, is suitable. In addition, the surface member 11a and the lining member 11b are preferably subjected to antibacterial treatment. Further, the material of the nose bridge 11 is not particularly limited as long as it has a function of preventing the return and fixing the shape, but it is preferable that the nose bridge 11 is a material that can be integrally disposed as combustible waste.

  Next, the ear hooks 12 are provided at both left and right ends of the mask body 10 to form a pair. Here, each ear hook 12 is fixed (joined) at the upper end portion and the lower end portion of the mask main body 10. In either one (for example, the upper end) of the fixing portion (joining portion), one end of the ear hook 12 is thermally bonded (for example, ultrasonic fusion) to the backing member 11b when the mask body 10 is thermally bonded. ing. Then, in the other fixing portion (joint portion) (for example, the lower end portion), the other end of the ear hook 12 is wave-stitched (for example, two eyes) to the folded portion C of the mask body 10 as shown in FIG. ) And are locked by these frictional forces. Here, the frictional force is set to such a degree that the relative position of the ear hook 12 with respect to the mask body 10 can be changed by an operation of pulling the wearer's ear hook 12 while the locked state is maintained during use. Is done. In addition, as the ear hook 12, it is suitable to use the string which has a stretching property like the product made from spandex (polyurethane), for example. Here, the number of eyes related to the wave stitching is determined from the point of view of avoiding annoyance of the exposed string (especially when it is long) and the appearance of the ear hook 12 that penetrates the last eye when worn. It is preferable to use an even number (for example, 2 or 4) so as not to be placed on the outside of the mask. An odd number (for example, three or five) is preferably used so that the tip of the ear hook 12 that penetrates the eye is not placed inside the mask when worn (FIG. 3 shows the former example).

  Here, the example of a more specific disposable mask is given. First, the nonwoven fabric which comprises the surface material member 11a and the back surface member 11b is comprised from the polypropylene nonwoven fabric which is the same material. However, the fibers of the outer surface member 11a are made of long fibers that are continuous and connected by a single thread, while the fibers of the backing member 11b are made of softer threads cut to about 1 to 51 mm. Composed of short fibers. The nose bridge 11 is polyethylene having a shape maintaining function. Furthermore, the ear hook 12 is a string made of polyurethane and polyester, and the thickness of the string is about 3 mm, for example.

  Using these members, the disposable mask according to this example is manufactured as follows. First, one end of the ear hook 12 (string) is heat-sealed to the upper left part of the back member 11b, and the other end is wave-sewn from the lower left part of the back member 11b. In addition, the number of eyes concerning wave sewing is two, and the space | interval of an eye is about 3 mm, for example. As a result, the other end of the ear hook 12 (string) protrudes from the last eye toward the back member 11b. Moreover, by passing the string, two small holes of about 1 mm, for example, are formed in the mask body 10. Thus, since the small hole formed with respect to the thickness of the string is small, as shown in FIG. 3, the ear hook 12 (string) is compressed in the hole. Occurs. Then, the other ear hook 12 (string) is joined to the mask body 10 in the same manner. In the above description, the method of performing wave stitching through a string on the needle, instead of opening a hole in the mask body 10 in advance, is exemplified. However, a method of opening a small hole in advance and passing the string there may be adopted. Good.

  Next, as shown in FIG. 4, the disposable mask 20 according to the second best mode has a mask main body 21 capable of covering at least the mouth of the wearer, and a pair of headrests 22 attached to both upper and lower ends. ing. Here, the headrests 22 are provided at both upper and lower ends of the mask body 20 to form a pair. Here, each headrest 22 is fixed (joined) at the right end and the left end of the mask body 20. In either one (for example, the right end) of the fixed portion (joint portion), one end of the headrest 22 is thermally bonded (for example, ultrasonic fusion) to the backing member when the mask body 20 is thermally bonded. Yes. In the other (for example, the left) fixing portion (joining portion), the other end of the headrest 22 is wave-stitched (for example, two eyes) to the folded portion D of the mask body 20, and these It is locked by frictional force. The configuration other than the above is the same as the first best mode.
