て形成されている。2. Description of the Related Art FIG. 11 is a partially cutaway explanatory view showing an example of conventional disposable pants. The main body of the disposable pants D is composed of a back sheet 1, a top sheet 2 and an absorber 3 housed therebetween, and the pants body is formed in an hourglass shape, and is folded in the front-back direction of the main body. The side portions are joined by welding lines 5 and 5 to form a pants type. The welding line 5 is formed by using ultrasonic sealing, heat sealing, or an adhesive. In the state of lamination in the welding line 5, two topsheets 2 and two backsheets 1 are stacked. The respective layers are joined and integrally bonded. Also, the upper body opening K1 and the lower leg opening K2
Elastic bodies 4a and 4c are additionally provided around the to form an elastic gather portion. The top sheet 2 is generally made of a water-permeable non-woven fabric mainly made of polypropylene fiber, the back sheet 1 is a water-impermeable sheet such as a polyethylene film, and the absorbent body 3 is a tissue, papermaking, crushed pulp. It is made of super absorbent resin, heat-fusible fiber, or the like.

The problem of prevention remained. It has been confirmed by the present inventors that this problem becomes more prominent when the backsheet 1 has a laminated structure of a water-impermeable film and a nonwoven fabric, as in the technique disclosed in JP-A-61-207605. It was

難があった。On the other hand, the welding line 5 generally has a shape as shown in FIG. That is, in FIG.
The welding line 5 is formed by a continuous fused portion W along the longitudinal direction of the pants body. The melting portion W having such a shape can firmly bond the top sheet 2, the back sheet 1, etc., but since the bonding is too strong, a large force is required when the welding line portion is peeled off after use. There was a problem with the detachability.

The back sheet is formed by laminating non-woven fabrics, and the side portion of the back sheet is formed by laminating only the two non-woven fabrics, and the side portion of the pants is formed by laminating the back sheet. The gist is that the non-woven fabric layer is welded. Also the second
The constitution capable of achieving the object of (1) is based on the point that the welding line of the side portion is continuously provided in the longitudinal direction with a mesh surface.

And prevent stuffiness in the pants. One of the non-woven fabrics that make up the backsheet
When the sheet is made of a heat-fusible non-woven fabric, the heat-fusible non-woven fabric melts and acts as a bonding material when forming a welding line, and the shape of the pants can be surely maintained. Further, by forming the welding line in a continuous shape in the longitudinal direction of the pant side portion with a net-like surface, the welding line has sufficient strength to maintain the pant shape during wearing and can be easily peeled off when detached.

FIG. 6 is an explanatory view of a laminated state showing another embodiment of the present invention. The topsheet 2 and the water-impermeable film 1b arranged above and below with the absorbent body 3 sandwiched therebetween are formed in a shape lacking the side portions S (provided on the nonwoven fabrics 1a 1 and 1a 2 of the backsheet). A pair of three-dimensional gathers 9, 9 made of a water-impermeable band-shaped material is attached to the upper surface of the side portion of the second member 2. That is, an elastic body 9a is attached to one side edge of the strip-shaped sheet, and the opposite side edge (may be the widthwise intermediate portion of the strip-shaped sheet) and the front and rear ends are bonded to the upper surface of the top sheet 2. Form a three-dimensional gather with one edge rising. Furthermore, on the lower layer side of the water-impermeable film 1b, a heat-fusible nonwoven fabric 1a 1 having a side portion S (preferably water-repellent treated) and a high melting point nonwoven fabric 1a 2 are laminated, and between the both nonwoven fabrics. Elastic bodies 4a, 4b, 4c are additionally provided. Therefore, the welding allowance for forming the pants type 5
a, 5b is constituted by a nonwoven 1a 1, 1a 2 of two layers, refractory by is faced the heat-fusible non-woven fabric 1a 1, 1a 1 together as shown in FIG. 8, thereby melting a portion of the member Bond the non-woven fabric 1a 2 and the like.

ａ1 との接合も確実なものとなる。As shown in FIG. 6, folding back portions 99 are provided at the front and rear ends of the high melting point non-woven fabric 1a 2 which is the outermost layer of the back sheet, and the folding back portions 99 are folded over the upper surface of the top sheet 2. It is preferable to bond them by adhesion, which makes it possible to form the opening edge of the trunk of the pants beautifully and softly.
FIG. 9 shows a longitudinal cross-sectional view of the welding margins 5a and 5b of this structure, in which the heat-fusible non-woven fabric 1a 1 is chipped at the upper ends of the welding margins 5a and 5b, and the welding may be insufficient. There is. In order to prevent such a welding defect, the high melting point non-woven fabric 1a 2 has a heat-fusible fiber (a fiber having a melting point similar to that of the heat-fusible fiber which is a main material constituting the heat-fusible non-woven fabric 1a 1 ). Is recommended to be contained in an amount of 10 to 80%, so that the high melting point nonwoven fabrics 1a 2 can be bonded together. The high melting point non-woven fabric 1a 2 is mixed with the heat fusible fiber to be laminated with the high fusible non woven fabric 1a 2.
The joining with a 1 is also reliable.

That is, (A) is a continuous fusion of circular fused portions W in the vertical direction of the pants, and (B) is a vertical fusion of inverted triangular fused portions W. Furthermore (C)
In the figure, (D) is a deformed lattice, and (E) is a hexagonal fused part W connected in the vertical direction. The structure common to these is that the welding line is continuous in the longitudinal direction of the pants side in a mesh shape and the fusion zone W is continuous to form an intersecting portion. It will not be easily peeled off even if is applied. Moreover, by setting the size of the meshes arbitrarily, it is possible to adjust the bonding strength so that the mesh can be easily peeled off by hand. The shape of the welding line 5 according to the present invention is not limited to the above embodiment, but may be any other shape as long as it has a mesh shape and is continuous in the longitudinal direction, but it is shown in FIG. It is not preferable that the melted portion W has a planar shape over the entire surface and that the melted portion W is not continuous in the vertical direction.

The adhesive strength was measured with respect to the entire area of the welded part (including the unwelded part corresponding to the hollowed-out part of the net), and the peeling strength between the top sheet and the laminated non-woven fabric was measured at a pulling speed of 30%.
It is measured in cm / min.
