Problems solved by technology

But on the other hand, because it is a plastically deformable material, once the sheet is stretched or deformed by some external force on the mask, it cannot return to its original shape.
In this way, there is still room for improvement in the shape maintenance of the mask in use

Embodiment 1

[0033] Such as figure 2 As shown in (a), in this embodiment, the belt-shaped member 4 is attached to the outer side of the covering part 2 . More specifically, after the belt-shaped member 4 is fixed to the covering material 5 with the hot-melt adhesive 6 , the covering material 5 is fixed to the covering part 2 with the hot-melt adhesive 6 . At this time, the belt-shaped member 4 is attached in a free state with respect to the covering part 2 . In addition, when referred to as a free state in the present application, it means that the two members are independent of each other without joining, and even if one is displaced, the other is not directly deformed by the displacement.

[0034] In the present embodiment, Technorot (registered trademark) H20000 manufactured by Mitsui Chemicals Corporation with a length of 150 mm and a width of 3 mm was used as the belt-shaped member 4 . And, the cover part 2 etc. are made using the following materials as image 3 (a) shows a sample...

Embodiment 2

[0040] Such as figure 2 As shown in (b), in this embodiment, such a sample is produced: the covering material 5 is fixed on the skin side of the covering part 2 by the hot-melt adhesive 6, and the belt-shaped member 4 is packed between the two to form It is in a free state with respect to the covering part 2 and the covering material 5 .

Embodiment 3

[0042] Such as figure 2 As shown in (c), in this embodiment, such a sample is produced: the covering material 5 is fixed on the skin side of the covering part 2 by the hot-melt adhesive 6, and the belt-shaped member 4 is fixed on the covering material 5 to face each other. The covering part 2 is in a free state.

Abstract

The objective of the invention is to provide a respirator for preventing slit generating on two sides of bridge of the nose when using. The respirator 1 has a cover part 2 for covering user mouth and nose, which is characterized in dividing the cover part 2 into two sides of longitudinal centre line of left and right part, a pair of left and right band component 4 composed by synthetic resin having plastic deformability block off a determined interval along the upper end of the cover part 2 and extend laterally.

Description

Technical field [0001] The present invention involves a mask. To put it in detail, it is a mask that prevents the gaps on both sides of the nose bridge when wearing it. Background technique [0002] Now, disposable masks are widely used.However, such a mask will produce gaps on both sides of the nose when wearing, and there is a problem that pollen or room dust enters from the gap.There is such a mask in the patent literature 1: a cup made of non -woven fabrics made of non -woven fabrics and non -woven fabrics attached to the subject.It is composed of deflection and non -elastic synthetic resin materials, forming a rectangular, and left and right pairs of enhanced films.According to the mask of Patent Literature 1, a mask that does not produce a gap between the peripheral part of the mask and the skin is provided. [0003] [Patent Literature 1] Japan special opening 2005-328937 [0004] In the mask of patent literature 1, the cup is composed of low -tech non -woven fabrics. It is...
