  • Patent number: 8912384
    Abstract: A compressed portion is formed in the absorbent article by compressing the absorber through a compression process. The compressed portion has a top-surface groove formed on the skin-contact-surface side, and a back-surface groove formed on the clothing-contact-surface side. A bottom portion of the top-surface groove is flat. Since the recessed portions are formed in the bottom portion of the back-surface groove through the compression process, a compression part where the density of the absorber is increased more than in an uncompressed portion and high compression parts where the density of the absorber is increased more than in the compression part are formed in the bottom portion. Thus, the absorbent article can be permeate into by a thick liquid, and is more likely to absorb liquid.
