Embodiment Construction

[0022] figure 1 To show a perspective view of a sanitary napkin as an example of the absorbent article of the present invention, figure 2 for figure 1 Section view of line II-II, image 3 and Fig. 4 are respectively shown according to the implementation form figure 2 Fig. 5 is a sectional view illustrating the bonded portion of the elastic member and the nonwoven fabric, and Fig. 6 is a perspective view showing an example of the manufacturing process of the nonwoven fabric forming the leak-proof wall.

[0023] figure 1 The absorbent article 1 shown in is a sanitary napkin, the X direction is the width direction, and the Y direction is the longitudinal direction. The regions sandwiching the center portion 2 of the absorbent article 1 are the front portion 3 and the rear portion 4 . Leakage prevention walls 5 and 5 extending in the longitudinal direction (Y direction) are provided on both side portions of the absorbent article 1 . Elastic members capable of exerting long...

Abstract

Disclosed in an absorbent article. The nonwoven fabric 6 which has the wave state uneven crease 7 as the wall for preventing leakage of the absorptive goods. The elastic part 16 is attached to this nonwoven fabric 6. The adhesive 32 is put in a spiral track manner around the elastic part 16. The bottom part 7b of the above- mentioned uneven crease 7 is attached to the surface of the elastic part 16 by the above-mentioned adhesive 32. As the adhesive 32 comes up with space in the direction of the length, the top part 7a of the uneven crease 7 or the inner side of the middle part 7c touch less to the adhesive 32, and therefore there is no possibility that the uneven crease 7 is squeezed and attach-fixed.

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins and disposable diapers, and more particularly to absorbent articles provided with leak-proof walls extending longitudinally on both sides. Background technique [0002] In the past, absorbent articles such as sanitary napkins, urine-absorbing pads, and disposable diapers have been developed. In these absorbent articles, it is required that the liquid-absorbing layer absorbs the excrement fluid reliably during wearing, and prevents the excretion fluid from leaking out of the absorbent article. Accordingly, leak-proof walls extending in the longitudinal direction are formed on both sides on the liquid-receiving side surface of the absorbent article. [0003] In the conventional leak-proof wall structure described above, generally, a non-stretch hydrophobic sheet extending in the longitudinal direction is joined to the top sheet of the absorbent article, and an elastic member ex...
