Absorber 40 is at least positioned at back waist region 12 and crotch region 13, stretches out in this embodiment from crotch region 13 to front waist area 11, back waist region 12.As shown in Figure 5, absorber 40 has absorptive core 44 and covers the tissue sheet 45,46 of core 44.As core 44, can use Time of Fluff Slurry, superabsorbent polymer granule or their mixture.As shown in Figure 2, the size on the horizontal X in front waist area 11, back waist region 12 of absorber 40 is greater than the size on imaginary cross central line Q-Q of this absorber 40.More particularly, absorber 40 at least in front waist area 11, back waist region 12 size on its horizontal X equate, the size in crotch region 13 on its horizontal X is along with going and reduce gradually towards imaginary cross central line Q-Q.
Surficial sheets 20, back-sheet 30 and absorber 40 utilize the joint elements of not shown hot-melt adhesive etc. to engage one another.The surface area of absorber 40 is less than the surface area of surficial sheets 20, back-sheet 30, and front-end edge 41, end edge 42 and the both side edges 43 of surficial sheets 20, back-sheet 30 self-priming acceptors 40 are stretched out.Thereby, be formed with in longitudinal Y outside and the horizontal X outside of absorber 40 the front fin 74, rear fin 75 and the flank sheet that do not have absorber 40.Flank sheet have be positioned at front waist area 11 the 1st flank sheet 71, be positioned at the 2nd flank sheet 72 of back waist region 12 and be positioned at the crotch flank sheet 73 of crotch region 13.At crotch flank sheet 73, the flank sheet elastomer 76 that Y extends is along the longitudinal installed.Flank sheet elastomer 76 by the adhering parts such as hot-melt adhesive be engaged in surficial sheets 20, back-sheet 30 at least any one, longitudinally under Y elongation state, installing in the mode that can shrink.
Between absorber 40 and back-sheet 30, dispose leakproof sheet material 50.Leakproof sheet material 50 can use the plastic foil of non-liquid permeability and breathability.The area of leakproof sheet material 50 is greater than the area of absorber 40.Thereby, can prevent from being absorbed urine that body 40 absorbs etc. and leak into outside diaper 1.
Back-sheet 30 and leakproof sheet material 50 utilize the joint elements such as hot-melt adhesive 90 to engage one another.The both side edges 93 of joint elements 90 is positioned at the position by horizontal X inner side than the both side edges of back-sheet 30 33, and is positioned at the position by horizontal X inner side than the both side edges of leakproof sheet material 50 53.Be formed with the disengaged region 94 that does not form joint elements 90 near of these both side edges 33,53.In disengaged region 94, back-sheet 30 and leakproof sheet material 50 do not engage one another.At leakproof sheet material 50, flank sheet elastomer 76 is installed.In this embodiment, many flank sheet elastomers 76 of wired (string) shape or strand (strand) shape are installed, these flank sheet elastomers 76 and joint elements 90 do not overlap.In addition, better, its part also can overlap with joint elements 90 in the horizontal X outside that at least a part for flank sheet elastomer 76 is positioned at joint elements 90.Joint elements 90 for example both can utilize coating machine coating etc. to be formed on continuously back-sheet 30, also can utilize spiral spraying etc. to be formed on intermittently back-sheet 30.
Hook element 81 is arranged on back waist region 12 by supporting sheet 83.Supporting sheet 83 has and is fixed on the extension 85 that the fixed part 84 of the 2nd flank sheet 72 and self-retaining portion 84 stretch out to the horizontal X outside of lateral margin 16, and hook element 81 is arranged on extension 85.Fixed part 84 is leaking between barrier cuff 60 and back-sheet 30 (with reference to Fig. 3 and Fig. 4), and this fixed part 84 is marked off by medial border 84a, the lateral border 84b that Y extends along the longitudinal and front-end edge 84c, the end edge 84d that transversely X extends.
The imaginary line R that intersection points B between the lateral margin 43 of the intersection point A between the lateral border 84b of fixed part 84 and front-end edge 84c and absorber 40 and imaginary cross central line Q-Q is linked is positioned on the 2nd flank sheet 72 and crotch flank sheet 73.That is, imaginary line R does not overlap with absorber 40, is positioned at its horizontal X outside.
The rear end 76b of flank sheet elastomer 76 extends to back waist region 12 sides than imaginary line R., flank sheet elastomer 76 and imaginary line R cross one another.The front end 76a of flank sheet elastomer 76 extends to front waist area 11 sides from crotch region 13.
Flexural rigidity on longitudinal Y of the 1st flank sheet 71 and the 2nd flank sheet 72 and crotch flank sheet 73 is about 0.10N/m～0.20N/m, and laterally the flexural rigidity on X is about 0.05N/m～0.10N/m.These methods below flexural rigidity utilization are measured.
the measuring method of flexural rigidity
Flexural rigidity utilizes KES experimental measurement.KES test is used the automatic pure bending testing machine of KES-FB2-AUTO-A (kato-tech limited company) to measure.In the scope that comprises imaginary line R, 10mm × 10mm is used as to sample strip, under the condition of 20 DEG C of temperature, humidity 60%, measures.More particularly, as sample strip, by the part that is positioned at crotch flank sheet 73 and be laminated with back-sheet 30, leakproof sheet material 50 and leak barrier cuff 60 cut on longitudinal Y for 10mm, on horizontal X for 10mm uses.
Such sample strip is placed on KES testing machine, uses the sensor that has full scale and reach the SEN10 of the torque sensitivity of 10gf/cm/10v, measures with curvature (1/cm).Respectively sample strip is measured to the flexural rigidity on longitudinal Y and horizontal X.
As shown in Figure 6, with regard to diaper 1, by hook element 81 is linked to loop member 82, thereby front waist area 11, back waist region 12 are connected, and can serve as the diaper 1 of Briefs type for wearer H dress.In the time wearing such diaper 1, existence is urinated, absorber 40 absorbs urine and becomes heavy, and diaper 1 entirety is pulled by the below in figure.At the intersection point A place of end of a side that is positioned at imaginary line R, utilize hook element 81 to keep diaper 1 at wearer's waist, at the intersection points B place of end of opposite side that is positioned at imaginary line R, diaper 1 is pulled downwards, and therefore, diaper 1 becomes and is pulled along imaginary line R.Intersection point A remains on wearer H reliably, and the flexural rigidity on the 2nd flank sheet 72 of imaginary line R present position and longitudinal Y of crotch flank sheet 73 is about 0.10N/m～0.20N/m, flexural rigidity on its horizontal X is about 0.05N/m～0.10N/m, therefore, even if diaper 1 exists, urinate can be not sagging because of its weight yet.Because diaper 1 can be not sagging because of the weight of absorber, therefore, it also can, with respect to wearer's waist landing, can not maintain the wearing effect that is sealed at wearer.
Above-mentioned due to the flexural rigidity of the 2nd flank sheet 72 and crotch flank sheet 73 is made as, therefore, these flank sheets are difficult to bending, can prevent from rolling or be rolled into surficial sheets 20 sides to back-sheet 30 sides.Thereby these the 2nd flank sheets 72 and crotch flank sheet 73 can be covered along wearer's buttocks.By the buttocks with fin covering wearer, thereby if Excreta is leaked from these flank sheets, also can keep this Excreta and prevent that it is attached on clothes.In addition,, by covering buttocks with fin, can provide also good diaper 1 of appearance.And in the situation that these fins are rolled into surficial sheets 20 side, the part being involved in enters into the inner side of diaper 1, Excreta is likely adhered to, but can prevent that this situation is in possible trouble.
Diaper 1 as described above is in the time wearing, and the imaginary line R being pulled is closely sealed along the thigh root of wearer H.Because imaginary line R is sealed at the thigh root that becomes the motion of lower limb basic point, therefore, can not hinder the motion of the lower limb of wearer H, can prevent urine etc. leakage.In addition, the diaper 1 that can utilize imaginary line R to keep wish to decline at the thigh root of wearer H, can prevent the landing of diaper 1.The flexural rigidity that flexural rigidity on longitudinal Y of the 2nd flank sheet 72 and crotch flank sheet 73 is greater than on 0.20N/m, horizontal X is greater than 0.10N/m, its overall hardening, can not concentrate on imaginary line R therefore act on the tension force of flank sheet in the time wearing, therefore, the imaginary line R of flank sheet is difficult to be sealed at wearer's health.
Imaginary line R is positioned at the horizontal X outside of absorber 40, does not overlap with absorber 40.Thereby imaginary line R can not be absorbed body 40 and block.In the situation that imaginary line R overlaps with absorber 40, the continuous tensile force from intersection point A to intersection points B can be truncated, and therefore, the tensioning state of flank sheet is destroyed, and inner side is likely rolled or be rolled into flank sheet to the outside of diaper 1.In the present invention, owing to can utilizing imaginary line R to maintain the extended configuration of flank sheet, therefore, these flank sheets can not be rolled or be involved in.
Because imaginary line R and flank sheet elastomer 76 intersect, therefore, utilize imaginary line R to keep flank sheet elastomer 76, can prevent that flank sheet elastomer 76 is sagging downwards.Thereby flank sheet elastomer 76 and the crotch flank sheet 73 that this flank sheet elastomer 76 is installed can be sealed at wearer's huckle, can prevent that leakage of exudates from arriving outside diaper 1.In addition, grabbing that the front-end edge 14 of diaper 1, end edge 15 pull and on while carrying, the crotch region 13 of diaper 1 is also raised along imaginary line R, therefore, also can easily arrange wearing effect.
Flank sheet elastomer 76 is arranged on the disengaged region 94 that is not formed with joint elements 90.In disengaged region 94, its flexural rigidity is less than the flexural rigidity in region that is formed with joint elements 90.Thereby, can comply with the flexible of flank sheet elastomer 76 and make crotch flank sheet 73 flexibly be sealed at wearer's lower limb.And flank sheet elastomer 76 is installed on leakproof sheet material 50, can be sealed at dividually wearer with back-sheet 30, be therefore more easy to closely sealed.In addition, owing to flank sheet elastomer 76 being installed in the less region of flexural rigidity, therefore, pull and on while carrying diaper 1, the power of carrying on this is easy to be delivered to flank sheet elastomer 76, can make crotch flank sheet 73 be sealed at wearer's huckle.A part in many flank sheet elastomers 76 overlaps with joint elements 90, the flank sheet elastomer 76 of this coincidence is pressed leakproof sheet material 50 and back-sheet 30 to wearer's thruster, and can comply with the flank sheet elastomer 76 not overlapping with joint elements 90, therefore, can make crotch flank sheet 73 more be sealed at wearer's health.
As the flank sheet elastomer 76 of present embodiment, use elastomeric yarn, but be not limited thereto, also can use and there is elastic sheet material etc.In addition, the rear end 76b of flank sheet elastomer 76 is positioned at the position by back waist region 12 sides than imaginary line R, but the meaning of said rear end 76b refers to the rear end in fact in flank sheet elastomer 76 with elastic part here.
Between the lateral margin 16 of imaginary line R and main body 10, be separately of a size of about 5mm～20mm.In addition, between imaginary line R and lateral margin 16, might not form abreast, therefore, even their immediate parts are also approximately greater than 5mm, even the part that they separate most is also approximately less than 20mm.Thereby the 2nd flank sheet 72 and crotch flank sheet 73 can stably cover wearer's buttocks.In the situation that separately size is less than 5mm, fin is easy to be rolled into the inner side of diaper 1, in the situation that separately size is greater than 20mm, can is pulled by the motion of wearer's lower limb and cause diaper 1 to be easy to dislocation.
As shown in Figure 2, size W1 on the imaginary cross central line Q-Q of main body 10 is about 180mm～300mm, be about 205mm in the present embodiment, the size W2 on the imaginary cross central line Q-Q of absorber 40 is about 70mm～100mm, is about 80mm in the present embodiment.The size W2 of absorber 40 is made as approximately 0.2 times～0.4 times of size W1 of main body 10., be made as W2/W1=0.2～0.4.By doing like this, crotch flank sheet 73 can not be rolled into the inner side of diaper 1, and can cover wearer's buttocks.
