Description of the Related Art A body fluid absorbent article disclosed in Japanese Patent Laid-Open No. 8-117274 covers an article body in which a liquid-absorbent core is interposed between a top sheet and a back sheet, and an upper surface of front and rear end portions of the body. And a liquid-resistant sheet that forms a pocket. By joining the peripheral portions of the liquid-resistant sheet at the front and rear ends of the main body, pockets are formed that open toward the opposite ends of the front and rear ends. The surface sheet is exposed at the central portion located between the front and rear ends of the main body.

る。The pocket in the known article is crushed when the wearer's abdomen and back are pressed against each other when worn. Since the crushed pocket is difficult to reopen even when the pressure contact force is released, the function as a pocket for inflowing and retaining excrement deteriorates. It is possible to use a stretchable sheet as the liquid resistance sheet, join the liquid resistance sheet in the width direction of the main body in an expanded state, and use the contracting force to open the pocket. If the contraction force of the core is higher than the rigidity of the core, the contraction force forms wrinkles in the core, and a gap is formed between the core and the surface sheet to prevent absorption of excrement.

When the second pocket P2 is pressed against the wearer's abdomen and back, the excrement exudes from the foam member 10 and moves to the first pocket P1, permeates the top sheet 2 and passes through the core 4
Is absorbed by. The excrement is impeded by the liquid-resistant sheet 5 located on the upper surface of the second portion 10b, which impedes the exudation to the outside.

うことはない。It is conceivable that a thread-shaped or film-shaped elastic member is fixed to the opening end of the liquid-resistant sheet 5 in an expanded state and the contracting force of the elastic member opens the pocket. It increases the rigidity and reduces the feeling of wearing. In this diaper 1, the flexible foam member 1
Since 0 is used, the cushioning property is good and the wearing feeling is not impaired.

As shown in FIG. 4, the diaper 1 includes elastic members 8 fixed to the side flaps 23 and both side edges 4 of the core 4.
A pair of barrier cuffs 12 that branch upward from the side flaps 23 extend in the longitudinal direction of the diaper 1. An elastic member 13 extending in the longitudinal direction is fixed to the free side edge portion 12b of the barrier cuff 12 in an extended state, and the contracting force of the elastic member 13 allows the barrier cuff 12 to rise up above the top sheet 2.
