Be that example is described with reference to the accompanying drawings the present invention with sanitary napkin below as disposable body fluid absorption article.
Be from looking with the sanitary napkin 1 shown in the oblique view of partly cut-away among Fig. 1 with the bottom side that contacts that wears short underpants.Sanitary towel 1 is by liquid permeability top flat 2, ventilating and moisture-permeable egative film 3 and be clipped in the moisture absorption body structure thing that the absorbent article core 4 between above-mentioned two 2,3 constitutes.Top flat 2, egative film 3 are overlapping mutually on the extended part of the periphery of absorbent article core 4, engage by at least one fusion in heatmeltable bonding agent etc. or the egative film 2,3, and form flap 6.
Fig. 2 is the profile that dissects along II-II line among Fig. 1.Sanitary towel 1 has the position 7 that lacks absorbent article core 4 between top flat 2, the egative film 3 at the central area of width.On this position 7, top flat 2 is in and the same flat condition in 7 surrounding zones, position, and egative film 3 engages with the inner face 2A of top flat 2 discontinuously by recessed, forms along the recessed of long side direction extension of sanitary towel 1 and is pickled with grains or in wine 11.Recessed poor 11 bottom 12 is positions that top flat 2 and egative film 3 overlap.The wide of in the illustrated example recessed poor 11 is 3～15mm, 1/8～6/8 of long total length for absorbent article core 4.
The top flat 2 of this sanitary towel 1 adopts the plastic sheeting of liquid permeability non-woven fabrics or perforate to make.
Egative film 3 for example adopts that to have air penetrability be 20～1500 seconds/100cc (measuring according to JISP-8177), be preferably 25～1000 seconds/100cc, rate of perviousness (measuring according to JISZ-0208) is 700～30000g/m
224hr, be preferably 1000～25000g/m
2The plastic sheeting of ventilating and moisture-permeable .24hr for example discloses this plastic sheeting with ventilating and moisture-permeable real opening in the clear 63-46119 communique.
Use and pulverize wood pulps or pulverize wood pulps and superabsorbent mixture of polymers etc. as absorbent article core 4.
