Example 1
Hereinafter, the structure of the wearing article 1 concerning Example 1 of this invention is demonstrated according to drawing.
1 to 7 show a first embodiment.

  As shown in FIGS. 1A and 1B, the wearing article 1 of the first embodiment includes an absorbent main body (an example of an interior part) 2 and a pair of front and rear waist members 3 and 3 (an example of an exterior part). . The absorbent main body 2 has a front part 20, a back part 21 and a crotch part 22. The front part 20 covers the wearer's front trunk (front part of the trunk) and extends in the trunk circumference direction X. The back portion 21 covers the wearer's rear trunk (the rear part of the trunk) and extends in the trunk circumference direction X. The crotch part 22 covers the crotch of the wearer between the front part 20 and the back part 21.

  The crotch portion 22 is connected to the front portion 20 and the back portion 21 and extends in the longitudinal direction Y orthogonal to the waistline direction X. The absorbent main body 2 constitutes part or all of the crotch portion 22.

  In FIG. 1A, the wearable article is worn in a state in which the crotch portion 22 is folded in two along a virtual line parallel to the waistline direction X. As a result, the ends of the front waistline member 3 and the rear waistline member 3 in the waistline direction X overlap each other.

  As shown in FIG. 1B, the absorbent main body 2 is provided with an absorbent core 24. The absorption core 24 absorbs body fluid. The absorbent core 24 is sandwiched between a top sheet 26 and a back sheet 27. The sheets 26 and 27 and the absorbent core 24 are stacked on each other.

In FIG. 1B, the top sheet 26 is made of a liquid-permeable thin nonwoven fabric and covers the skin surface of the absorbent core 24. A cuff 25 may be provided on the top sheet 26. The top sheet 26 consists essentially of a non-stretchable nonwoven fabric.
In the present invention, the “skin surface” means an inner surface that directly or indirectly contacts the wearer's skin when the diaper is worn, and directly or indirectly faces the wearer's skin.

The back sheet 27 covers the non-skin surface of the absorbent core 24 and is made of a liquid-impermeable resin sheet. An exterior nonwoven fabric (not shown) may be bonded to the non-skin surface of the back sheet 27 and laminated. The resin sheet and the exterior nonwoven fabric are essentially non-stretchable.
In the present invention, the “non-skin surface” means an outer surface that does not contact the wearer's skin when the diaper on the side opposite to the skin surface is worn, and does not face the wearer's skin.

  In FIG. 1A, the absorbent main body 2 is constructed between a front waistline member 3 and a rear waistline member 3. That is, the end portion in the longitudinal direction Y of the front portion 20 of the absorbent main body 2 is attached to the front waistline member 3. On the other hand, the end portion in the longitudinal direction Y of the back portion 21 of the absorbent main body 2 is attached to the rear waistline member 3.

  The front and rear waistline members 3 each form a pair of front flaps F and rear flaps F protruding from the absorbent main body 2 in the waistline direction X, and each of the flaps F is a part of the front and rear waistline portions. Configure. That is, as shown in FIG. 1A, each of the flaps F protrudes in the waistline direction X from the crotch part 22 and extends in the waistline direction X from both edges E1 of the absorbent main body 2 (the crotch part 22).

Each of the front and rear waistline members 3 is formed by cutting a continuous laminated body L (FIG. 5A) described later.
As shown in FIG. 3, each of the waistline members 3 is composed of a laminate in which an elastic member 30 and first to third sheets 31 to 33 are laminated to each other.

The said 1st sheet | seat 31 and a pair of 2nd sheet | seat 32 are comprised with the nonwoven fabric which has air permeability. The said 1st sheet | seat 31 is continuously extended in the trunk periphery direction X from a wearer's front torso or back torso to both sides. On the other hand, the pair of second sheets 32, 32 are not provided on the front cylinder and the rear cylinder, and are stacked on the first sheet so as to be disposed on both sides, and are separated from each other in the cylinder periphery direction X. Are arranged.

The elastic member 30 is sandwiched between the first sheet 31 and the second sheet 32 and expands and contracts in the waistline direction X. The elastic member 30, the second sheet 32, and the first sheet 31 are stacked on each other at the front and rear flaps F as shown in FIG. 1B. Accordingly, the flap F has three layers.

The elastic member 30 is cut at the front and rear body portions 34 between the pair of second sheets 32 and 32 that are disposed apart from each other in the waist direction X. Thereby, the contraction force of the elastic member 30 is not exerted on the front and rear body portions 34 between the pair of second sheets 32 and 32.

As shown in FIG. 1A, in the case of the present embodiment, one end 30e of the cut elastic member 30 protrudes from the second sheet 32 toward the front and rear body portions 34.
The elastic member 30 is for fitting each waistline member 3 to the wearer. As the elastic member 30, for example, a material including a plurality of rubber threads, flat rubber, a film, or a thermoplastic resin can be employed.

When thread rubber is employed as the elastic member 30, only the convex portions 31p of the first sheet 31 and the elastic member 30 in FIG. 2B are used without applying an adhesive to the entire surfaces of the first sheet 31 and the second sheet 32. The laminated body may be formed by applying an adhesive and sandwiching the elastic member 30 between the first sheet 31 and the second sheet 32.
In addition, the 1st sheet | seat 31 and the 2nd sheet | seat 32 may not be the said adhesive agent, but may mutually weld and be joined (seal).

In the front and rear body portions 34 of the waistline member 3, the third sheet 33 having a smoother surface than the nonwoven fabric is laminated on the skin surface side of the first sheet 31. Since the third sheet has a smooth surface, the pattern is easily printed.
On the non-skin surface of the third sheet 33, a pattern 35 indicated by an imaginary line in FIG. 1B and a broken line in FIG. 2A is printed.

The third sheet 33 in FIG. 1B is disposed between the pair of second sheets 32 and 32. Accordingly, the third sheet 33 covers the exposed end portion 30 e of the elastic member 30 and wraps the second sheet 32 at the end of the second sheet 32. Thereby, it can prevent that the edge part 30e of the elastic member 30 contacts a wearer's skin.

As shown in FIG. 2B, the first sheet 31 may be embossed to form irregularities. In this case, the first sheet 31 may be bonded to the second and third sheets 32 and 33 only at the embossed convex portion 31p of the first sheet 31 as indicated by the xxx in FIG. 2B.

In FIG. 1A, the absorptive main body 2 is disposed across the front body portion 34 and the rear body portion 24 where the second sheet 32 is not disposed. In this embodiment, the absorbent main body 2 is disposed between the pair of third sheets 33, 33 and is indirectly joined to the first sheet 31 only through the third sheet 33.

  The absorbent main body 2 may be formed with a leg-hole portion that is constricted along the wearer's leg portion. Another elastic member made of, for example, rubber thread may be provided along the leg circumference and the leg circumference of the waistline member 3 so as to follow the wearer's leg circumference.

  When the wearing article is a diaper, a male surface fastener (not shown) may be fixed to the rear waistline member 3, while a female surface fastener may be fixed to the front waistline member 3.

Note that a tape material coated with a fastening agent may be used in place of the male fastener, and in this case, it is necessary to form a surface on which the fastening agent is easily adhered to the front waistline member 3 or the like. There is.
Moreover, when a wearing article is a pants type, the edge parts of the waist direction X of the front flap F and the rear flap F may be welded.

Next, a method for manufacturing the worn article will be described with reference to FIGS.

The continuous sheet W1 of FIG. 5A that becomes the first sheet 31 of FIG. 3 is introduced between the pair of concavo-convex rolls 51 and 52 of FIG. 7 while being conveyed in the conveyance direction X1 along the waist direction X, and is embossed. Is given. The embossing is performed before the discontinuous sheet W2 is arranged. The embossing is performed not only on the portion where the discontinuous sheet W2 described later of the continuous sheet W1 is disposed, that is, not only on the portion serving as the flap F but also on the portion where the discontinuous sheet W2 is not disposed. It may be broken.
The detailed method of embossing is disclosed in JP2002-165830A or JP2004-174234A, and all the descriptions thereof are incorporated here.

After the embossing, an adhesive is applied to the convex portion of the continuous sheet W1 by the applicator 56. Note that the continuous sheet W1 and the discontinuous sheet W2 are both made of a breathable nonwoven fabric.
