[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable pants-type wearing article, and more particularly to a disposable pants-type wearing article in which laterally opposed sides of the disposable pants-type wearing article are intermittently joined.

[0002]

2. Description of the Related Art In general, training pants and pants-type disposable diapers as disposable wearing articles are laminated panels comprising a liquid-permeable top sheet and a liquid-impermeable back sheet, and in particular, in the case of diapers, absorb between them. An elastic member is attached to each of the waistline and the leg circumference of the laminated panel in order to obtain a fit to the body while wearing and a function of preventing leakage of bodily fluid with a basic configuration of a laminated panel having a body interposed therebetween. . Further, generally, such an article is formed by folding the laminated panel in two so that the top sheet is located on the inside and joining opposing side portions of a portion that becomes a waist around the front and rear body, thereby forming a pair of the body opening and a pair of the body opening. An opening around the leg is formed.

[0003]

In the disposable pants-type wearing article, the joining between the front body and the back body is made by one or a plurality of continuous bonding lines from the trunk opening to the leg opening. However, in such articles, the excretion is made by the wearer, and when this is taken off, if this is pulled down to the wearer's feet, the excrement is stool,
In the process of lowering the stool, it is not rare that the stool adheres to the body part that did not adhere at the time of defecation. In order to avoid such a situation, it is preferable that, as is already known, the joined front body and the rear body are torn apart so as to be separated from each other.

[0004] As described above, in the conventional article, the joining is performed by a continuous bonding line, so that the tearing operation is not easy. Further, in such a continuous bonding line, the opposite side portion of the article is in a sealed state, and air permeability cannot be obtained.

[0005] The present invention is mainly concerned with the opposing side of the article because it is easy to tear the opposing side of the article, but is not inadvertently torn during wearing, and also has the air permeability of the opposing side. The joining structure of the side portions is an issue.

[0006]

An article according to the present invention for solving the above-mentioned problems comprises a liquid-permeable top sheet and a liquid-impermeable back sheet, and has laterally opposite sides of a front body and a back body. Are joined, and elastic members are provided at the trunk opening and the leg opening, respectively, and the joining of the laterally opposed sides of the front and rear bodies is
In the joint area with a predetermined width dimension extending in the longitudinal direction of the side
Along the vertical direction and the horizontal direction of the joint area.
Consists of a large number of joined dots arranged at regular intervals
Related to the improvement of disposable pants-type wearing articles,
It is characterized by.

That is, the features of the present invention are as follows:
The joining dots are a first joining dot and a second joining dot
The first joining dots and the second joining dots
The joint area may be arranged alternately at a constant interval in the longitudinal direction.
The first joining dots are laterally separated from the joining area.
And the second joining dots are connected in parallel with each other.
The first joining dots adjacent to each other in the longitudinal direction of the region.
And the number of the second joining dots is
The point is that the number is smaller than the number of the first joining dots.

[0008]

The worn article can be easily removed from the wearer by tearing the front body and the back body along the joint area. The air permeability inside and outside the article is obtained through the non-joined portions between the joined dots.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A disposable diaper as an embodiment of an article according to the present invention will be described below with reference to the drawings.

In FIG. 1, a diaper 1 includes a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, an absorber 4 (see FIG. 2), a waist elastic member 5, and a leg elastic member 6. Contains. Gathers are formed around the periphery of each of the trunk opening 7 and the leg opening 8 by the contraction action of the elastic members 5 and 6. In the laterally opposed side portion 9 of the diaper 1, the side portions 10A and 11A of the front body 10 and the back body 11 are integrally joined in a joining area 14. The absorber 4 is not always necessary for implementing the present invention.

In FIG. 2, the diaper 1 comprises a laminated panel 1 'formed by a top sheet 2, a back sheet 3, and an absorber 4 interposed therebetween. The top sheet 2 is made of a thermo-crimped thermoplastic fiber, is a nonwoven fabric in which the fibers are entangled under the action of a high-pressure water flow, and has elasticity and elasticity. The absorber 4 is preferably made of a shaped product of ground pulp containing 5 to 15% by weight of a superabsorbent polymer. The back sheet 3 has a two-layer structure and comprises a liquid-impervious sheet 16 made of a polyethylene-based thermoplastic elastomer and having high elasticity and elasticity, and a thermo-crimped thermoplastic fiber. Are intermittently joined with a hot melt adhesive. The liquid impermeable sheet 16 faces the top sheet 2 via the absorber 4, and the nonwoven fabric 17
The outer surface of the diaper 1. The liquid impervious sheet 16 imparts liquid impermeability to the back sheet 3.
The nonwoven fabric 17 gives the outer surface of the diaper 1 a cloth-like texture. In addition, by intermittently joining the liquid impermeable sheet 16 and the nonwoven fabric 17 to each other, the strength of the back sheet 3 is improved without impairing elasticity. On the liquid-impermeable sheet 16 of the back sheet 3, a waist elastic member 5 made of a plurality of thread rubbers and a leg elastic member 6 made of a plurality of thread rubbers and consisting of front and rear members 6A and 6B are provided. Was bonded with a hot melt adhesive under stretching. Front and rear members 6
A and 6B are hardly stretched in the crotch region 15 between intersections that cross each other. The elastic members 5 and 6 are continuously supplied along the flow direction in the continuous production line of the diaper 1 and run across the width direction of the diaper 1, and both cut edges thereof are on opposite sides in the lateral direction. Part 9 (see FIG. 3)
, Faces the side edge of the back sheet 3.

The top sheet 2 and the back sheet 3 have the same outer shape, and extend outward from the outer periphery of the absorber 4,
They are joined to each other at their extending portions. The laminated panel 1 ′ is bisected in the vertical direction, folded so that the top sheet 2 is on the inside, and the laterally opposed side portions 10 A and 11 A of the front body 10 and the back body 11 are overlapped with each other to form a joint area 1.
4, the body opening 7 and a pair of leg openings 8 are formed by being integrally joined. In the diaper 1 thus configured, the thread rubbers 5 and 6A on the front body 10 substantially overlap the thread rubbers 5 and 6B on the back body 11 side, and the body rubber opening 7 and the leg opening 8 are respectively formed. It is substantially continuous in the direction of its circumference.

In FIG. 3, a joining area 14 extends from the trunk opening 7 to the leg opening 8 in the longitudinal direction of the side portion 9 and is joined to a joining dot 14A to which materials of the front and rear bodies 10 and 11 are joined by an adhesive. , And the non-joined portion 14B. Each of the joining dots 14A has a diameter of 2 to 4 mm and is separated from the joining area 14 in the lateral direction by two pieces.
