[0002]
[Prior art and problems to be solved by the invention]
Absorbent articles such as disposable diapers have become compact and easy to carry due to improvements in construction and materials used.
However, the weight of the package in which a plurality of absorbent articles are still stored is quite heavy, and some of the packages exceed 3 kg, and it is very heavy for a mother or a caregiver to have such a package.
Moreover, in order to obtain sufficient leakage prevention properties in absorbent articles such as disposable diapers, as proposed in JP-A-2-309940, a proposal for improving the prevention of leakage at the lower part of the absorber is provided. However, there is no effective proposal for preventing leakage from the side of the absorber. Moreover, as another proposal, since it is common to arrange a member other than the absorbent body or the leak-proof sheet on the side portion of the absorbent body, in a conventional disposable diaper, when the leakage prevention property is improved, it is disposable. It was common for the weight of diapers to increase.
