Profile when oblique view that Fig. 1, Fig. 2 have cut open for the part of representing sanitary napkin 1 usefulness respectively and the line A-A in Fig. 1 cut open.Sanitary napkin 1 by the bottom side thin layer 5 of the top side thin layer 2 of liquid permeability, opaque liquid, be installed in the core body with liquid-absorbent 4 between these two thin layers 2,5, and prevent to leak with blanketing thin layer 3 and constitute.
On top side thin layer 2, in a part of zone of core body 4 at blanketing at least, be formed with along the width of core body 4 and be recess 2a and protuberance 2b continuous wavy fluctuating, that extend along the longitudinal direction of core body 4.Yet the bottom side of recess 2a also can not combine with the upper side of core body 4 when the bottom side of using bonding agent with recess 2a is combined in the upper side of core body 4, make recess 2a and protuberance 2b produce warpage even exert pressure, also can easily restore to wave-like from the outside.Recess 2a on the top side thin layer 2 and protuberance 2b can be formed on blanketing and on the whole zone of core body 4, also can only be formed on the middle section place the neighboring area on core body 4.
On top side thin layer 2 and bottom side thin layer 5, by the extended laterally along the longitudinal direction position of the both side ends of core body 4 with by the extended laterally position of the both side ends broad ways of core body 4, thermal welding means that can be by bonding agent or the like are bonded to each other the inner face of these two thin layers 2,5.Top side thin layer 2 and core body 4 also are bonded to each other to two extruding grooves 6 that longitudinal direction extends by the both sides of the edge along core body 4.
Extruding groove 6 is positioned at the position than the more close inboard, both sides of the edge of core body 4, and formation is crooked towards the central part of core body 4 is protruding.Extruding groove 6 is used for preventing separating in 4 generations of the use top side of sanitary towel 1 thin layer 2 and core body.
Prevent to leak the upper side of the outside perimembranous of sanitary towel 1 with blanketing thin layer 3 blanketing, both side ends is turned back to bottom side thin layer 5, and is combined on the lateral surface of bottom side thin layer 5 by bonding agent or thermal welding means.On preventing to leak, also be formed with the peristome 3a of longitudinal in the position of the middle section that is positioned at core body 4, so that make recess 2a and protuberance 2b on the top side thin layer 2 expose to the open air out by this peristome 3a place with blanketing thin layer 3.Top side thin layer 2 does not combine by the circumferential edge of peristome 3a with preventing to leak with blanketing thin layer 3, is formed with to prevent that menses from leaking the recessed pocket 7 of usefulness between these two thin layers 2,3.Though not shown in the drawings, yet, the elastomeric element with retractility that makes peristome 3a be located the function left upward by top side thin layer 2 can also be installed at least at the place, both sides of the edge of the circumferential edge of peristome 3a.
Fig. 3 is the fragmentary cross-sectional view of expression top side thin layer 2 usefulness, and it shows the section shape of recess 2a and protuberance 2b.Can be taken between 1.5～10.0 millimeters by the height L between bottom side to the top side of protuberance 2b of recess 2a, and be preferably between 3.0～10.0 millimeters.As height L during less than 1.5 millimeters, menses are crossed protuberance 2b easily and are flowed along the width of sanitary towel 1, and this is one of reason that causes the menses transverse leakage.Interval W between the adjacent projection 2a can be taken between 1.0～15.0 millimeters, and is preferably between 5.0～15.0 millimeters.On top side thin layer 2, the middle section place in the zone that by core body 4 blanketing is formed with height L and all bigger recess 2a and the protuberance 2b of W at interval, and is formed with recess 2a and the protuberance 2b littler than middle section in the neighboring area.
The hydrophilic non-woven of non-woven fabrics that top side thin layer 2 can be made of the hydrophobicity non-woven fabrics of handling through the hydrophilic chemical reagent and the fiber that is immersed into the hydrophilic chemical reagent or the like is made.These non-woven fabrics preferably adopt through Overheating Treatment can produce the material that composite fibre curling, that have high resiliency constitutes.
The fiber number of fiber is preferably between 1～6 danier.The order of non-woven fabrics pay (Japanese basis weight) can be taken at 20～80 the gram/square metre between, be preferably in 30～80 the gram/square metre between.As the structure of top side thin layer 2, can constitute than higher nonwoven fabric laminate with the density that the upper strata is the lower non-woven fabrics of the density of per unit area, lower floor is per unit area.If for instance, the upper strata can use fiber number be 4 daniers, order pay be 20 the gram/square metre non-woven fabrics, lower floor can use fiber number be 2 daniers, order pay be 40 the gram/square metre non-woven fabrics.Have the top side thin layer 2 that this structure constitutes, its upper strata non-woven fabrics is faster to the seepage velocity of menses than lower floor non-woven fabrics to the seepage velocity of menses.Because the upper strata non-woven fabrics is faster than lower floor non-woven fabrics to the seepage velocity of menses, thereby can prevent the outside place of retained menstruation at top side thin layer 2.
Core body 4 is made of timber short fiber pulp and the mixture with superabsorbent hydrogel particle, and integral body by chiffon paper blanketing, and is compressed to needed thickness.
Profile when oblique view that Fig. 4, Fig. 5 have cut open for the part of the expression another kind of sanitary napkin 10 different with sanitary towel as shown in Figure 1 and the line B-B in Fig. 4 cut open.Sanitary napkin 10 is made of the bottom side thin layer 12 of the top side thin layer 11 of liquid permeability, opaque liquid and the core body with liquid-absorbent 13 that combines with one inner face in these two thin layers 11,12 at least.
Below top side thin layer 11, also its middle section of clamping 13a core body 13 ground higher than the height of its neighboring area 13b dispose bottom side thin layer 12.Be formed with at top side thin layer 11 places along the width of core body 13 and be recess 11a and protuberance 11b continuous wavy fluctuating, that extend along the longitudinal direction of core body 3.At the 13b place, neighboring area except the middle section 13a of core body 13, top side thin layer 11 is combined in the upper side place of core body 13 by bonding agent (not shown) etc.From the extended laterally along the longitudinal direction position of the both side ends of core body 13 with from the extended laterally position of the both side ends broad ways of core body 13, be combined on the bottom side thin layer 12 by bonding agent or thermal welding means.
Be preferably between 1.5～4.0 millimeters by the height between bottom side to the top side of protuberance 2b of the recess 11a of top side thin layer 11.Interval between the protuberance 11b adjacent one another are is preferably between 2.0～10.0 millimeters.
If adopt the body liquid absorption articles that has constructed according to the invention, when the body fluid that flows into recess spreads along the longitudinal direction, protuberance will form flow barrier, thereby can prevent the transverse leakage of body fluid.Recess and protuberance also can easily return to original-shape producing owing to top side thin layer skew and pressure effect when being out of shape, thereby can keep the flexibility with contact skin.
Core body is to be the high article that rise in middle part, makes the easy broad ways elongation of top side thin layer, thus can not produce compressing to being high position of rising, middle part on the core body, thus can keep its resilient flexible.
Therefore, if adopt the body liquid absorption articles that has constructed according to the invention, can closely contacting with labia of these article as a health part with skin contact surface, thus can prevent that body fluid from leaking by absorbing surface and as producing between the skin of body part.
