In addition, the present invention provides a multi-stage fold having a second annular elastic member extending from between the outer edge of the absorber and the annular elastic member inside the dome shape to prevent leakage with the elastic member, thereby preventing leakage. The effect can be further improved.

Further, the present invention provides a state in which an absorber is placed on a leak-proof sheet in a stretched state, and an elastic member is tensioned in an annular shape so as to be in contact with the outer periphery of the absorber or at a distance along the absorber. In this case, the expansion of the leak-proof sheet is released by placing and joining the topsheet from above, and the tension of the elastic member is restored. The present invention relates to a method for manufacturing a dome-shaped absorbent article that forms a shape. Absorbers having a flat circular shape are placed on the long stretchable leak-proof sheet made of polyethylene or the like at intervals, and elastic members are fixedly attached in a state of being tensioned in an annular shape so as to surround each absorber, respectively. After the top sheet is placed and joined from above, it is punched annularly along each outer periphery of the annular elastic member. Thereby, the annular punched sheet is automatically narrowed to the dome shape by the restoration of the tension of the elastic member.

Further, if a dome-shaped absorbent article having an inner surface sheet formed by punching in an annular shape is embossed with a hemispherical shape or the like, the dome shape can be easily maintained, and the desired dome shape can be conveniently formed. is there. By such a manufacturing method, the dome-shaped absorbent article of the present invention can be easily and effectively obtained.
