されている。2. Description of the Related Art Conventionally, disposable absorbent articles such as disposable paper diapers and sanitary napkins have been provided with leak-proof gathers, three-dimensional gathers, double cuffs and other leak-proof means around the user's legs. ing. However, this type of leakproof means cannot prevent leaks from the back and abdomen of the user, and therefore, in recent years, leakproof gathers have been gathered on the waist of the user as disclosed in JP-A-3-195556. , Those with leakage prevention means such as three-dimensional gathers and double cuffs are used.

In the following description, unless otherwise specified, the absorbent pad or the pad-type diaper that is stacked on the use surface side of the main body of the paper diaper is called "auxiliary pad".

とが知見された。However, when the auxiliary pad is laid on the use surface of the product paper diaper main body when worn, the thickness of the absorber of the auxiliary pad to be superposed is added, and the auxiliary pad is attached to the absorbent body of the main body of the diaper diaper. Due to the increase in overall rigidity due to the double absorbent body, free deformation of the waist barrier cuffs is obstructed, and it is difficult to adhere to the skin no matter how wide the waist barrier cuffs are raised. It was found that the function was not fully exerted.

There is a problem in that an excessive contraction force makes the wearer feel a feeling of pressure and makes the wearing feeling significantly inferior. In addition, when gathers are provided on the waist flap portion, the product contracts in the width direction, making it difficult to see the center of the product. This causes a mounting deviation, and as a result, causes the product to not exhibit its full function.

Elastic stretchable members 7B, 7B, 7B are arranged. Therefore, the barrier cuff W is erected by the contracting force of each elastic expansion / contraction member 7A, ... And 7B. Moreover, since gathers are formed on the barrier cuff W by the elastic elastic members for standing 7B, 7B, 7B, it is possible to form no gathers on the waist flap F. If gathers are not formed on the waist flap F, the product does not expand and contract in the width direction, and the center of the product is easy to see. In other words, it is possible to prevent misalignment,
As a result, the function of the product can be fully exerted.

空間はより深いものとなる。By the way, as shown in the upper part of FIG. 4, the waist barrier cuff W is pressed toward the product by the barrier cuff B at the widthwise side edge 4B portion (see FIG. 1). The standing height of the distal edge E1 is small. On the other hand, the 4A portion on the center side in the width direction (see FIG.
reference. In (), since there is no pressing by the barrier cuffs B, the barrier elastic cuffs 7B, 7B, 7B tend to raise the barrier cuffs W high. However, 4B
Since the rising height of the distal edge E1 of the barrier cuff W is small in the section, the distal edge E of the barrier cuff W in the section 4A is small.
As a result, the barrier cuff W stands up while inflating the middle portion in the height direction outward, as shown in the lower part of FIG. Thereby, the pocket of the barrier cuff W is formed, and the wrapping of the auxiliary pad 10 is also ensured. At the same time, the waist flap F is deformed and lifted up, and the absorber 3 is also lifted while deforming slightly, so that the pocket space becomes deeper.

い。Furthermore, in this lifted state, the strong contracting force of the elastic elastic members 7B, 7B, 7B for standing acts on the barrier cuff W itself, so that the barrier cuff W stands up almost vertically. At the same time, although the elastic elastic members 7A, 7A for contact are weak, the contracting force raises the barrier cuff W. However, the elastic contact elastic member 7
Even if the contracting force of A and 7A is weak, since the standing force of the barrier cuff W by the elastic elastic members 7B, 7B and 7B for standing is large, the standing of the barrier cuff W is surely secured as a whole. Since the contracting force of the elastic contact elastic members 7A, 7A is not strong, there is no excessive pressure contact with the wearer's skin.

Even if 0 is overlapped on the use surface side, the standing up of the barrier cuff W is ensured, the auxiliary cuff W does not lie down or warp, and the auxiliary pad 10 can be reliably wrapped.

ｍに渡って設置した。By the way, as the material for the leg-surrounding barrier sheet 4 and the waist barrier sheet 6, a breathable and liquid-impermeable plastic film or a water-repellent non-woven fabric treated with silicon can be used. Further, as shown in FIG. 7 as an example in the case of the barrier cuff W, a waterproof sheet 7C made of a plastic film or the like is attached to a water repellent non-woven fabric or a non-water repellent non-woven fabric in order to surely prevent liquid permeation. It is good to intervene. As a preferable nonwoven fabric, a polypropylene nonwoven fabric manufactured by a melt blown method is more suitable. A sheet having a basis weight of 5 to 30 g / m 2 is adhered in a bag-like form, and the bag-shaped edge is a free end. The elastic member may be a plurality of thread-shaped members made of natural rubber, synthetic rubber, polyurethane or the like, or a band-shaped member. In the embodiment, the strong contraction force of 7B, 7B, 7B is caused by the barrier cuff W.
Since it acts on itself, the barrier cuff W acts so as to stand almost vertically. As the elastic elastic member 7A for contact, two 560 denier urethane yarns are stretched by 200%,
Installed over 250 mm in the width direction of the product, the elastic elastic member 7B for standing up is made up of about 5 560 denier urethane threads.
250m in the product width direction with 200% elongation at mm intervals
It installed over m.

Also, the expansion / contraction rate is 2
The elongation stress at 0 to 90% is 0. The elastic stretchable member for standing 7B
Is O. When it is 10 to 1.50 N, the wearer does not feel a feeling of pressure and does not create a gap in the waist peripheral portion, and can exhibit excellent leakage prevention performance.
