The density of the density ratio absorbent cores 32 of absorbing sheet 31 is large, and absorbing sheet 31 and absorbent cores 32 all alongst dispose and reach the width outside of aftermentioned the 1st compression unit.Be guided to the diffusion of body fluids in the width outside of the 1st compression unit to the higher absorbing sheet of density, body fluid also is transported to the lower zone of absorbent cores 32.Owing to diffusion of body fluids is improved absorption efficiency, so, be not easy to exceed the absorptive capacity in the middle section that comprises the scavenge port contact area.
In the present embodiment, upside absorbent cores 32B and downside absorbent cores 32A are integrated.Upside absorbent cores 32B and downside absorbent cores 32A can separately form, also can be integrally formed.The absorbent cores 32 of present embodiment is by with upside absorbent cores 32B and integrated formation of downside absorbent cores 32A.When absorbing sheet 31 and absorbent cores 32 form the structure of split, can be in addition bonding with the bonding agent of heat molten type bonding agent etc.
Between absorber 30 and surface patch 10, be provided with the sheet material 80 that contains the Chinese medicine material.Sheet material 80 is configured in the scavenge port contact area at least.The scavenge port contact area is the zone of connecting airtight with user.By sheet material 80 is located at the middle section that comprises this scavenge port contact area, can easily give user with Chinese medicine ingredients.In addition, the scavenge port contact area is that body fluid is discharged maximum zones.By sheet material 80 is located at middle section, can alleviate with fragrance ingredient the abnormal smells from the patient of body fluid, improve and use sense.
Sheet material 80 contacts with the pulp fiber of absorbent cores.Sheet material 80 is the rectangle lamellar from the plane, has 4 bight 80A, 80B, 80C, 80D as the outboard end of the outboard end of length direction and width.The bight of sheet material has forward corner 80A, the 80B that is positioned at the front side and is positioned at rear bight 80C, the 80D of rear side.Structure about sheet material 80 will describe in detail in the back.
From the plane, around at least a portion of sheet material 80, formed compression unit.This compression unit is to form at thickness direction compressed absorbent 30 and surface patch 10 at least.Compression unit has the 1st compression unit 23 and the 2nd compression unit 24.The 1st compression unit 23 is in the along its length configuration of the width outside of sheet material 80.The 2nd compression unit 24 is configured in the length direction outside of sheet material 80.The 2nd compression unit 24 is configured in bight 80A, the 80B of sheet material 80, the width inboard of 80C, 80D.
Specifically, dispose the 2nd compression unit 24 in the length direction outside and the width inboard of forward corner 80A, the 80B of sheet material 80, disposing the 1st compression unit 23 in length direction inboard and the width outside of forward corner 80A, 80B.The 1st compression unit 23 and the 2nd compression unit 24 are disposing discretely.
For example, if the 1st compression unit 23 and the 2nd compression unit 24 are configured to ring-type and the sheet material 80 of side configuration within it continuously, then the compression unit of the bight of sheet material 80 and ring-type disturbs, and can not make the area of sheet material enough large.
But, because the bight that the 1st compression unit 23 and the 2nd compression unit 24 dispose discretely and dispose sheet material in the crack betwixt, so, with the 1st compression unit 23 is compared with the structure that the 2nd compression unit 24 disposes continuously, the bight can be configured between the 1st compression unit 23 and the 2nd compression unit 24, can dispose more large-area sheet material.
In addition, discontinuous because the 1st compression unit 23 and the 2nd compression unit 24 disconnect, so, can suppress body fluid and exceedingly spread along compression unit.For example, if also spread along the 2nd compression unit along the body fluid of the 1st compression unit diffusion, then body fluid may too spread towards length direction.But the length direction outboard end of the 1st compression unit and the 2nd compression unit disconnect, and spread towards the 2nd compression unit from the 1st compression unit thereby can suppress body fluid.
The absorbent commodity 1 that consists of like this is when inwards being pushed from the width outside under the state that user uses, take the 1st compression unit as basic point towards the inboard distortion of width.Fig. 4 is the sketch map of the deformation form of the absorbent commodity 1 under the expression user mode.Fig. 4 is take section shown in Figure 3 as benchmark, is installed on the state of underwear S.Fig. 4 (a) is the state before the distortion, and Fig. 4 (b) is the state after the distortion.
Under the state before distortion, shown in Fig. 4 (a), the sheet material 80 of absorbent commodity 1 is roughly level and smooth state, is disposing opposite to each other with the scavenge port of user.When the middle section that is disposing upside absorbent cores 32B being applied from the width outside power towards the width inboard from this state, shown in Fig. 4 (b), a pair of the 1st compression unit 23 is towards the inboard distortion of width.
If absorbent commodity 1 then more is squeezed via compression unit by the absorbent cores of width inboard than compression unit by the inboard extruding from the width outside towards width.At this moment, absorbent cores by the face of sheet material side, do not dispose thin paper etc. and contact with pulp fiber.In addition, pulp fiber soft and flexibly the distortion.
Therefore, by towards the inboard extruding of width the time, pulp fiber is deformed into convex easily at absorbent commodity 1, and in addition, the distortion of pulp fiber is not suppressed by thin paper etc., so, be directly passed to sheet material 80.Compare with the state before the distortion, upside absorbent cores 32B is near to the user side joint.Like this, surface patch 10 and sheet material 80 more dispose near user ground.
In addition, the 2nd compression unit extends at width.When from the width outside towards the inboard active force of width, suppress distortion towards the width inboard by the 2nd compression unit, can suppress absorbent cores between the 1st compression unit and too be out of shape and become convex.
In addition, compression unit also has the 3rd compression unit 25, the 4th compression unit 26 and point-like compression unit 27.The 3rd compression unit 25 disposes to get more forward side than the 2nd compression unit 24 that is positioned at the front side.The 4th compression unit 26 disposes more by rear side than the 2nd compression unit 24 that is positioned at rear side.Point-like compression unit 27 is configured in the width outside of the 1st compression unit 23 and the length direction outside of the 2nd compression unit 24.
Be formed with to point-like compression unit 27 devices spaced apart a plurality of.Point-like compression unit 27 is configured in the width outside of the 1st compression unit 23 and not to be configured in the width of the 1st compression unit 23 inboard.Therefore, when absorbent commodity 1 is applied power from the width outside towards the width inboard by the lower limb of user etc., the zone (having formed the zone of point-like compression unit) in the width outside of the 1st compression unit keeps level and smooth state, simultaneously, the zone of the width inboard of the 1st compression unit (disposing the zone of upside absorbent cores 32B) is easily near the user side.
In addition, the zone in the width of the 1st compression unit 23 outside, owing to formed point-like compression unit 27, so rigidity improves, easily giving the 1st compression unit 23 from the Stress Transfer in the width outside.Therefore, be configured in that the sheet material 80 of width inboard of the 1st compression unit 23 is easier to be connected airtight with user, can give user with the composition of Chinese medicine material.
In addition, the central authorities of the length direction of the 1st compression unit 23 constitute, and towards the outstanding convex in the width outside, the length of the width of the 1st compression unit 23 is the longest.Therefore, absorbent commodity is being applied from the width outside when being deformed into convex towards the power of width inboard, can be easy to guarantee the height of crushed element, sheet material 80 easily and health connect airtight.In addition, along the body fluid of the 1st compression unit diffusion, towards the length direction outside little by little towards the width flows inside.Therefore, can suppress side leakage.
The compression unit of absorbent commodity is as long as at least compaction table dough sheet 10 and the formation of absorber 30 ground of thickness direction T, can adopt various structures.For example, can be processed to form with pressurization processing, embossing, its shape can be latticed, cellular.In addition, the 1st compression unit 23 and the 2nd compression unit 24 of present embodiment are made of a plurality of compression units of discontinuous configuration respectively, but also can form continuous wire.
In addition, the sheet material in the present embodiment 80 is the structures that can separate with absorber 30.For example, if use for a long time absorbent commodity, then absorber 30 is curling because of dampness etc., and absorber 30 is not deformed into convex towards the user side sometimes.But because sheet material 80 can separate with absorber 30, so even in the curling and indeformable situation that becomes convex of absorber 30, surface patch 10 also separates with absorber 30 with sheet material 80, surface patch 10 and sheet material 80 can be out of shape towards bodyside.
