Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pants-type disposable diaper. More specifically, the present invention relates to a pants-type disposable diaper that can be easily attached and detached even by a wearer who has a fingertip that is inconvenient or has insufficient gripping force.

[0002]

2. Description of the Related Art Conventionally, pants-type diapers have been used.
Elastic elastic members are arranged around the waist and leg openings. Such a pants-type disposable diaper is worn by lifting the waist opening from the toe of the wearer to the waist while firmly holding the waist opening with the fingertips. Because each elastic elastic member arranged on the periphery etc. tightens the relevant part of the body,
When pulling up to wear a diaper, a certain pinching force is required at the fingertip.

[0003] However, fingertips are inconvenient due to paralysis, injuries, illnesses, etc.
Alternatively, when elderly or sick people who have difficulty in agile movement wear diapers themselves, hold the diaper and hold the diaper's waist opening due to slipping of the fingertips, etc. May be difficult to raise sufficiently. Also, to undress such a pants-type disposable diaper, it is usually carried out by breaking the joint between the front body and the back body, which is arranged on both side edges of the diaper. Since the wearer has a weak gripping force, it is very difficult to break the joint, and the wearer cannot easily undress.

Various proposals have been made to solve these problems. For example, a method of arranging a loop-shaped pinching portion at both side joints of a pants-type disposable diaper (Japanese Utility Model Laid-Open Publication No. Hei 6-11720), or a method of arranging a plurality of fingertip engaging portions arranged in parallel around the waist circumference. Method (Japanese Patent Laid-Open No. 11-1)
04180) has been proposed.

[0005]

However, in the method of arranging the loop-shaped pinching portions at the joints on both sides of the pants-type disposable diaper (Japanese Utility Model Laid-Open No. 6-11720), only the upper portions of both sides of the diaper are removed. Although it will be pulled up, in this case, each elastic elastic member arranged around the waist and the periphery of the opening around the leg is likely to be caught on the part that protrudes to each part of the body, and the pants-type diaper quickly Not enough to raise it.

[0006] Further, in the case of a diaper in which such a loop-shaped gripping portion is arranged, the loop-shaped gripping portion becomes very disturbing after being worn, and may be caught somewhere during or during wearing. In the case where it is folded during wearing and hits the skin, the feeling of wearing is very poor. Furthermore, even when clothes such as pants are put on from above the diaper, the waist portions are raised and the appearance is not good because of the holding portion.

In the method of arranging a plurality of fingertip engaging portions arranged in parallel around the waist circumference (Japanese Patent Laid-Open No. 11-104180), a double outer sheet is used, and the first outer sheet is A fold portion that is folded and opens toward the crotch region, and a window portion that opens outward to a portion of the second outer sheet adjacent to the fold portion,
A fingertip can be engaged when pulling up the pants-type diaper.

However, in this proposal, there is a problem that the structure of the fingertip engaging portion is very complicated, so that it is difficult to manufacture the fingertip engaging portion. In addition, since the fingertip engaging portion is formed by a relatively small opening, it is difficult for a person who has a fingertip disability, such as a person who is slow to move due to paralysis, injury, or the elderly, to easily perform an operation. There are also problems. Furthermore, in this proposal, since the opening of the fingertip engaging portion is formed only toward the crotch region, it cannot be used at all when pulling down the pants-type diaper.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional pants-type disposable diaper and to provide a pants-type disposable diaper which can be easily and securely pulled up and down when attaching and detaching. It is in. Furthermore,
It is another object of the present invention to achieve the above object and to effectively prevent loose stools and the like from leaking from the back and abdomen with a simple structure.
