JPH0754244Y2 - Disposable pants - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to disposable pants, and more particularly to infant training pants, hem pants, and incontinence pants.

[Conventional technology]

Conventionally, as this type of pants, JP-A-62-243806,
62-243807 and others.

[Problems to be solved by the device]

When the stool is excreted in this type of pants, if the stool is pulled down from the waist of the wearer toward the toes or pulled out and removed, the stool may inadvertently adhere to the legs or the like. To avoid this, it is preferred to tear the joint longitudinally along it so that the front and back bodies are separated. However, since the joining portion is made by continuously welding the front and rear bodies, it is difficult to tear such a joint.
In particular, the part that has deviated from the joint is torn, and it is difficult to smoothly tear along the joint, and it often takes time.

In addition, since the waist opening and leg openings of the pants are in close contact with the body by the elastic members attached to them, the inside of the pants easily gets damp when excreted in the pants, and not only does the wearer feel uncomfortable. It can also cause skin diseases.

It is an object of the present invention to provide pants that can easily tear apart the front and rear body joints of the pants when they are to be taken off and can also reduce stuffiness inside.

[Means for Solving the Problems]

In order to achieve the above object, the present invention interposes an absorbent core between inner and outer sheets, and forms leg opening forming portions at both central edges of the sheet and waist opening forming portions at both longitudinal ends of the sheet. Further, elastic members are attached to these opening forming portions to form a laminated body, and the laminated body is folded so that the front and rear bodies overlap and the inner sheet is positioned inside, and side edges of the cores of the front and rear bodies. The leg openings and the waist opening are formed by welding and joining the both sides extending outward from the two sides, and the welding joints on the both sides are located inside the both side edges of the front and rear body. Assuming some disposable pants.

According to the present invention, in the above-mentioned premise structure, a nonwoven fabric containing thermoplastic fibers is used as the inner and outer surface sheets, the welding joint is formed by welding the fibers, and the welding joint is intermittently provided in a longitudinal direction. The both side portions are torn apart from each other along the zone of the welded joint so that they can be separated from each other.

[Action]

In the pants of the present invention having the above-mentioned configuration, if the waist opening at the upper end of the welded joint or the leg opening at the lower end is grasped with both hands and the front and rear bodies are pulled away from each other, the front and rear body becomes relatively easy. It is torn along the welded joint and separated.

The inside of the pants communicates with the outside air through the respective parts that are not welded in the zone of the welded joint.

〔Example〕

The outline of an embodiment of the pants according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, inner and outer sheets that are long in the longitudinal direction
The absorbent core 4 is interposed between the layers 2 and 3 to form the laminated body 1. The inner and outer sheets 2 and 3 are made of a non-woven fabric containing a thermoplastic fiber, and have a leg-opening forming portion 5 with a concave shape on both side edges of the center (inseam)
And straight waist opening forming portions 6 are formed at both ends in the vertical direction. Although not shown, as is well known, a liquid impermeable sheet such as a plastic film may be provided at least on the lower surface of the absorbent core 4 in order to prevent leakage of excreted liquid, as is well known. The absorbent core 4 is mainly composed of linear pulp or a mixture thereof with superabsorbent polymer particles, and has a narrow crotch region and is formed in a so-called hourglass shape. Stretchable members 7 and 8 are attached to the leg opening forming portion 5 and the waist opening forming portion 6 so as to extend along the respective portions. The elastic members 7 and 8 are made of a material having elastic elasticity,
Any of natural or synthetic rubber, polyurethane foam, plastic film exhibiting expansion and contraction elasticity by heat treatment, and the like, both relatively narrow and wide can be used.

The laminated body 1 is folded so that the front and rear bodies 1a and 1b are overlapped with each other through the vertical center line L and the inner surface sheet 2 is located inside, and both sides are heat-welded or ultrasonic-welded appropriately inside the both side edges 9. Thus, the welded joint portion 10 is provided, and the front and rear bodies 1a and 1b of both waist portions are joined to each other. This allows
Pants having both leg openings 1c and waist openings 1d are formed, and an extension 11 is provided outside the zone of the welded joint 10.

As shown in FIG. 4, the welded joint portion 10 is provided intermittently or intermittently. In the welded joint portion 10 shown in FIG. 5, the joint portion 10a at a required portion is thickened to enhance the joint strength, and the joint portion 10b between them is thinned to lower the joint strength.

[Effect of device]

According to the pants according to the present invention, when the front and rear body parts of the waist are pulled so that the welded joints of the front and rear bodies are separated from each other when the pants are removed from the wearer, the welded joints of the front and rear body parts of the waist are intermittent. In addition, since the welded joint is made by welding the thermoplastic fibers of the non-woven fabric, the fibers that have been welded to each other may be cut or one of them may be deprived to the other, and the front and back bodies are along the zone of the welded joint. Very easily torn and separated. Therefore, it does not take time to remove the pants so that the stool does not adhere to the pants and the legs of the wearer. Moreover, since the inside and outside of the pants are ventilated through the respective portions which are not welded and joined in the zone of the welded joints, the stuffiness inside the pants is also suppressed.

Furthermore, if the pants contain materials such as plastic film that are not suitable for incineration as general waste, when disposing of the used pants as general waste, the inner and outer sheets are separated from each other and are not suitable for incineration. However, if the welded joint is continuous as in the above-mentioned conventional technique, at least a part of the continuous welded joint remains after the tear separation, which is an obstacle. However, it is difficult to separate the inner and outer sheets from each other, but in the pants according to the present invention, there is no such difficulty because the welded joints are intermittent.
