Definitions
- the present invention relates to a disposable diaper, training pants, a diaper for incontinent patients, pants for wearing a urine absorbing pad, a diaper cover, and the like, which are suitable for use as disposable diapers.
- Patent Document 1 discloses an invention relating to a method for producing an absorbent wearing article (absorbent garment).
- Training pants according to this method have a body fluid absorbing chassis and a fastening system.
- the chassis has elastic members extending in the waist direction in each of the front and rear waist regions, and the hook and the loop of the mechanical fastener forming the fastening means intersect with the elastic members. It is attached to one.
- Patent document 1 W ⁇ 01/87209
- gathers may occur in the chassis as the elastic member contracts, and gathers may also occur in hooks and loops attached to the chassis.
- Hooks that are commonly used every day have high rigidity. Gathering is rarely caused by shrinkage of elastic members of training pants. Force is flexible and supple instead of high rigidity. In training pants when using a low hook part, gathers easily occur in the hook part. However, when gathers are formed on the hooks, some of the numerous hooks formed on the hooks are hidden in the valleys of the gathers and cannot be engaged with the loops. In such a hook portion, the number of hooks that work effectively is reduced, and the loop portion, which is the mating partner, is easily released.
- the distance between the hook portion where the gathering occurs and the loop portion engaging with it is compared.
- a so-called peeling force is apt to act, so that the loop part is easily detached from the hook part.
- gathers occur at the hook portion in the disposable wearing article.
- the adhesive sheet and the target in the case of using an adhesive sheet and a sheet forming a target area where the adhesive sheet can be repeatedly fixed are used instead of the mechanical fastener. The same can be said for the sheet to be formed.
