(2) detailed construction of absorber

Then, the structure of absorber 30 is specifically described.Absorbent cores 31, which at least abut region S1 in discharge port, has convexity Portion 33.Middle protrusion 33 can also abut region S1 front lateral regions S2 from discharge port and extend.Middle protrusion 33 is in discharge port abutment area Domain S1 is configured across center line CL.Center line is the line at the center in the width direction for link absorbent commodity, is along preceding The line of rear direction.Middle protrusion 33 refers to, the thickness region thicker than the thickness of the lateral border of absorbent cores.The absorbing material of middle protrusion 33 Weight per unit area can also be higher than the absorbent cores 31 in the region in addition to middle protrusion 33 that discharge port abuts in the S1 of region Weight per unit area.Preferably, absorbent cores 31 of the weight per unit area region 41 lower than the 1st by the part of rear side are thinner than convexity The thickness in portion 33.It is further preferred that the absorbent cores 31 of posterior region S3 entirety are thinner than the thickness of middle protrusion 33.Due to middle protrusion 33 Thickness it is thicker, therefore be easy to fit in the discharge port of wearer.On the other hand, due to the thickness of the absorbent cores of posterior region Than relatively thin, the rigidity of posterior region is relatively low, therefore is easy to follow the movement of the leg of wearer, can reduce when keeping leg mobile Sense of discomfort.The end edge of middle protrusion 33 is the front-end edge in the 1st low weight per unit area region 41.The front-end edge of middle protrusion 33 is with after The 1st lateral condensation portion 81 stated is adjacent.

In the section along front-rear direction L of absorbent commodity 1 shown in Fig. 3, the therefrom edge end edge 33R of protrusion 33 Thickness direction T extend the rear surface 33RS of the middle protrusion 33 and non-skin opposite face angulation α of middle protrusion 33 be greater than Therefrom the front-end edge 33F of protrusion 33 is along the front surface 33FS of the middle protrusion 33 extended thickness direction T and the non-flesh of middle protrusion 33 Skin opposite face angulation β.Angle [alpha] be the end edge 33R of rear surface 33RS and the therefrom protrusion 33 of middle protrusion 33 forwards The skin opposite face angulation of the middle protrusion 33 extended.In addition, angle beta be middle protrusion 33 front surface 33FS with from convexity The skin opposite face angulation for the middle protrusion 33 that the front-end edge 33F in portion 33 rearward extends.Due to the front surface of middle protrusion It is smaller with skin opposite face angulation, therefore the thickness of the front-end edge of middle protrusion gently changes, and can fit in ratio The position of the discharge port of wearer on the front.On the other hand, since the angle changing rate of the end edge side of middle protrusion is big, convexity The end edge in portion is easily made into bending basic point, can be after discharge port abuts and is arranged between region and posterior region by middle protrusion The deformation basic point that ora terminalis is formed, abutting region and posterior region in discharge port can be with the shape of the body of wearer cooperatively It is deformed into different shapes.Further, since the end edge of middle protrusion is easily made into bending basic point, therefore sharp under the posture lain down Absorber is deformed with bending basic point, more adaptation body can be deformed into.

Absorber 30 has the 1st low weight per unit area region 41, the 2nd low list in low weight per unit area region 42 and the 3rd Plane accumulates weight area 43.Here, " low weight per unit area region " refers to, by having the list lower than surrounding absorbent cores 31 The region that the absorbent cores 31 of position area weight are constituted or the region without absorbent cores 31.In this way, " low weight per unit area Region " is the concept in the region that the weight per unit area comprising absorbent cores 31 is zero.Under the posture that wearer lies down, absorbability The posterior region of article configures between underface, i.e. buttocks and the bed surface of the buttocks of wearer.Due to being formed in posterior region The 2nd low weight per unit area region rigidity it is relatively low, therefore to wearer assign sense of discomfort it is smaller.In addition, utilizing the 1st Low weight per unit area region and the 2nd low weight per unit area region, the absorbing material for constituting absorbent cores are not easy to support in discharge port It connects and is moved between region (or wing region), the right part of posterior region and the left part of posterior region.Thereby, it is possible to Inhibit to cause the absorbing material for constituting absorbent cores locally to be concentrated by the movement under wearing effect.As a result, in absorbent commodity Wearing effect under can mitigate the sense of discomfort of wearer.Thus, wearer especially is also not easy to feel under the posture lain down To sense of discomfort.

The weight per unit area of the absorbent cores 31 in low weight per unit area region 41~43 is preferably low weight per unit area The weight per unit area of absorbent cores (in addition to middle protrusion) around region 41~43 60% hereinafter, more preferably 50% with Under.

In the case where absorbent cores 31 are the regions without " low weight per unit area region ", core covering is also across low list Plane accumulates weight area and wraps up 31 entirety of absorbent cores.In this case, even if absorbent cores 31 are truncated as multiple regions, absorption Body 30 is also integrally formed using core covering.

1st low weight per unit area region 41, the 2nd low weight per unit area area in low weight per unit area region 42 and the 3rd Domain 43 becomes the changed boundary of rigidity of absorber 30.Thus, the 1st low weight per unit area region 41, the 2nd low unit plane The product low weight per unit area region 43 of weight area 42 and the 3rd is equivalent to the easily deformable region of absorber 30.

1st low weight per unit area region 41 abuts between region S1 and posterior region S3 in discharge port along width direction W extends.Utilize the 1st low weight per unit area region, it is suppressed that absorber abuts the deformation in region to absorber in discharge port The influence that the deformation of posterior region generates, absorbent commodity abuts region in discharge port and posterior region is easy to independently deform. Thus, it is possible to the discharge port of absorbent commodity is abutted region along the shape configuration of the in-leg of wearer, and by absorbability The posterior region of article along the buttocks of wearer shape configuration.Before 1st low weight per unit area region 41 is set to alar part 3 The rear side at the center on rear direction L and be absorber 30 posterior lateral margin front side.1st low weight per unit area region 41 is in front and back It is arranged on the L of direction across the end edge of alar part 3.As a result, due to the 1st low weight per unit area region 41 in the longitudinal direction across It configures with crossing the end edge of the alar part of the base end part as alar part, therefore can be truncated certainly in the 1st low weight per unit area region The power that the leg of wearer applies alar part inhibits the power to travel to the situation of posterior region.
