Become.

Further, a welded portion 7 with a linearly extending portion 3 is formed in the cover portion 2 on the inner side of the boundary line 5. When the cover portion 2 and the outer extension portion 3 are configured as separate members, the cover portion 2 and the outer extension portion 3 can be configured integrally with the weld portion 7. Moreover, if it makes it linear welding, it can weld easily.

  As shown in FIG. 4, the cover part 2 is provided with the surface layer 2c and the back surface layer 2d, and is comprised by laminating | stacking the collection layer 2e in the middle. The outer extension 3 is formed by superimposing and welding two layers of the surface layer 2c and the extension of the back layer 2d.

  Each layer is composed of a nonwoven fabric of thermoplastic synthetic resin such as polypropylene or polyethylene, and nonwoven fabrics of various manufacturing methods such as spun pond and melt blow are used according to the purpose of each layer. In the present embodiment, the surface layer 2c is made of polypropylene, a basis weight of 40 g / m 2, and a spun pound nonwoven fabric, and the back layer 2d is made of polypropylene, a basis weight of 20 g / m 2 and a melt blown nonwoven fabric. For the intermediate layer 2e, polypropylene, a basis weight of 20 g / m2, and a nonwoven fabric produced by a melt blow manufacturing method is used.

  Here, the outer extension 3 is configured to be less rigid than the cover 2. The configuration of the covering portion 2 and the extension portion 3 may be a configuration having different rigidity depending on the number of stacked layers, or may be a configuration having different rigidity depending on a difference in fiber density.
