Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a disposable mask suitable for use by a dentist, a worker at a food production site, or the like.
[0002]
[Prior art]
The nonwoven fabric disposable mask described in Japanese Patent Application Laid-Open No. 7-275384 is composed of a low stretch nonwoven fabric at the front portion that comes into contact with the face and a high stretch nonwoven fabric at the rear portion that hangs around the ear. This highly stretchable nonwoven fabric can be obtained by heat-treating a web containing thermally crimpable conjugate fibers.
[0003]
[Problems to be solved by the invention]
When the non-woven fabrics containing the crimped fibers are overlapped, the crimped fibers of the respective non-woven fabrics are entangled with each other and are difficult to peel off. When the known mask made of such a non-woven fabric is used to wrap around the ear, it is difficult to identify the masks one by one in the part. Therefore, for example, it may be difficult to accurately and quickly take out only one mask from a box in which a plurality of masks are packed.

DETAILED DESCRIPTION OF THE INVENTION
The details of the disposable mask according to the present invention will be described with reference to the accompanying drawings.
[0007]
1 and 2 are a partially broken plan view of the mask 1 whose front and rear are in the left-right direction, and a perspective view when the mask 1 is in use. However, the illustration of the mask wearer is omitted in FIG. The mask 1 is configured by superimposing two non-woven fabrics 1A and 1B having the same shape and the same size, and bonding the non-woven fabrics 1A and 1B at the front edge portion 5 and the rear edge portion 6 of the mask 1. The rear edge portion 6 includes an intermediate portion 13 and upper and lower portions 16 and 17 positioned above and below the intermediate portion 13, and the intermediate portion 13 extends further rearward than the upper and lower portions 16 and 17. Nonwoven fabric 1A, 1B is joined. In such a mask 1, the two nonwoven fabrics 1 </ b> A and 1 </ b> B form an annular body, the front edge portion 5 and the vicinity thereof form a covering portion 2 that covers the wearer's mouth and nose, and the rear edge portion 6 and the vicinity thereof. Forms a band 3 for hanging around the head. Non-woven fabrics 1A and 1B comprise 30% by weight or more of heat-melting synthetic fibers, more preferably 30% by weight or more of heat-melting synthetic fibers that are crimped and stretchable, and more preferably heat treatment of composite fibers. It is a stretchable thing containing 30 weight% or more of the crimped stretchable synthetic fiber obtained by doing. The front edge portion 5 and the extending portion 6A that are joined to each other are in a state where these fibers are melted and solidified under heat and pressure. Therefore, in these joint portions 5 and 6A, the nonwoven fabrics 1A and 1B are made into a thin single film, and have higher rigidity than the nonwoven fabrics 1A and 1B.
[0008]
FIG. 3 is a side view of the trailing edge 6 when a plurality of masks 1 are overlapped with the same outer shape. At the trailing edge 6, the nonwoven fabrics 1 </ b> A and 1 </ b> B overlap each other, and the extending portions 6 </ b> A are separated from each other by the thickness of the nonwoven fabrics 1 </ b> A and 1 </ b> B. Although not shown, the front edge portion 5 and the side surface shape in the vicinity thereof are also the same as in FIG. In such an overlapping mask 1, the fibers of the nonwoven fabrics 1 </ b> A and 1 </ b> B may be entangled and closely attached, so that it is difficult to identify and grip each nonwoven fabric one by one. However, the film-like front edge 5 and the extended portion 6A are easy to hold because they are separated from each other. In particular, since the portion 6A extends rearward from the nonwoven fabric portions of the upper and lower portions 16 and 17 in the vicinity thereof, the presence of the portion is well conspicuous and much easier to grip than the front edge portion 5. is there.
[0009]
FIG. 4 is a view similar to FIG. 1 showing an embodiment of the present invention. The rear edge 6 of the mask 1 may be joined by edges 16A and 17A provided with a large number of dots in the upper part 16 and the lower part 17 in addition to the extended part 6A.
[0010]
5 and 6 are also a partially broken plan view of the mask 1 illustrating the embodiment of the present invention and a perspective view when it is in use. In this mask 1, the covering portion 2 is formed by joining the overlapping non-stretchable or low-stretchable nonwoven fabrics 4 </ b> A and 4 </ b> B having the same shape and size at the front edge portion 5. The band portion 3 is made of relatively overlapped nonwoven fabrics 9A and 9B having the same shape and the same size, and these nonwoven fabrics 9A and 9B are joined at the extending portion 6A at the trailing edge. As the nonwoven fabrics 9A and 9B, stretchable nonwoven fabrics 1A and 1B used for the mask 1 of FIG. 1 can be used. The nonwoven fabrics 4A, 4B and 9A, 9B of the covering portion 2 and the band portion 3 are overlapped and joined at the intermediate portion 10 in the front-rear direction of the mask 1 so that the nonwoven fabrics 4A, 4B are on the outside.
[0011]
As shown in FIG. 5, the band portion 3 is obtained by applying first and second cut lines 11 and 12 penetrating through the respective nonwoven fabrics 9A and 9B. The first cut line 11 is a U-shaped (or inverted U-shaped) line that opens from the front edge 5 to the rear edge 6 of the mask 1. The cut line portions 11A and 11B extending in parallel and the cut line portion 11C extending in the vertical direction are configured. The second cut line 12 is inside the U-shape of the first cut line 11, and is constituted by cut line portions 12A and 12B which are parallel to the cut line portions 11A and 11B and parallel to each other. The portion sandwiched between the cut line portions 12A and 12B is an intermediate portion 13, and this intermediate portion 13 is higher than the upper and lower portions 16 and 17 positioned above the cut line portion 12A and below the cut line 12B. Further, it extends rearward, and the nonwoven fabrics 9A and 9B are joined to each other at the extended portion 6A.
[0012]
In the mask 1 of FIG. 5 configured as described above, when the extended portion 6A is pulled rearward, the band portion 3 extends rearward, and the mask 1 becomes an annular body shown in FIG. It becomes possible. The band part 3 forms two lines in the vicinity of the covering part 2 and forms a single line in the vicinity of the center of the back of the head. The nonwoven fabrics 4A and 4B used for the covering portion 2 and the nonwoven fabrics 9A and 9B used for the band portion 3 can form the leading edge portion 5, the intermediate portion 10, and the extended portion 6A by welding the nonwoven fabrics together under heat and pressure. Thus, it is preferable to contain 30% by weight or more of heat-meltable synthetic fiber. In this mask 1, the front edge part 5 and the extension part 6A where the nonwoven fabrics 4A and 4B, 9A and 9B are joined act in the same way as the mask 1 of FIG. 1 and have the same effect. In addition, in this mask 1, since the band part 3 can extend long back, the advantage that the amount of the nonwoven fabric used as the band part 3 can be reduced as compared with the mask 1 of FIG. In addition, since the extending portion 6A of the band portion 3 is formed only in the form of a film and extends rearward, not only the holding of each of the plurality of masks 1 is facilitated, but also the band portion 3A. The extension operation of the part 3 is also facilitated. Further, when the mask 1 is manufactured, after the first and second cut lines 11 and 12 are applied to the overlapped nonwoven fabrics 9A and 9B, or before the application, the rear extending portion 6A is welded. Part 3 can be formed. According to such welding, there is no possibility that parts other than the extension part 6A are unnecessarily welded.
[0013]
7 and 8 are also similar to FIGS. 5 and 6 showing an embodiment of the present invention. In the mask 1, a third cut line 21 extending from the extended portion 6A to the first cut line portion 11C is provided between the parallel second cut line portions 12A and 12B in parallel with the portions 12A and 12B. The rear edge intermediate portion 13 including the extended portion 6A in the case of FIG. Thereby, the extended portions 6B and 6C and the nonwoven fabric portions 13A and 13B are formed. When each of the extending portions 6B and 6C is held and the band portion 3 is extended rearward, as shown in FIG. 8, the entire band portion 3 is divided into upper and lower two lines.
[0014]
【The invention's effect】
In the disposable mask according to the present invention, the overlapped nonwoven fabric is joined at the front edge portion and the rear edge intermediate portion, and the rear edge intermediate portion is extended rearward from the remaining portion. Even if they are aligned and overlapped, it is easy to pinch the masks one by one accurately and quickly.
