As shown in Fig. 4 (a), absorbent main body 20 has a pair of leakproof pads in the both sides of the length direction X along diaper 40、40.Leakproof pad 40 is formed as follows:The doubling of sheet material 42 of the water-repellancy of rectangle will be made, makes to be in doubling shape Overleaf piece 22 and positive dough sheet 21 are extended between the 21E of position for the lateral region configuration of the sheet material 42 of state, and make in pair The broken line of the sheet material 42 of folding state is located at width Y foreign side.The sheet material 42 of leakproof pad 40 is constituted in absorber 25 Side absorbent body 23d non-skin is engaged with respect to surface side using bonding agent 40a with the position 21E that extends of positive dough sheet 21.In other words, Positive dough sheet 21 extends position 21E with extending position 21E than this and more outward filling the side of body 30 and adjacent to the extension portion as being located at The sheet material 42 of position 21E part is engaged.By the engagement, the junction surface 43 of X extensions along its length is formed.Junction surface 43 than by Width Y foreign side is more leaned in the curved guide portion of above-mentioned opening 231a formation, is leaning on width Y's than the curved guide portion Interior side does not form junction surface 43.In addition, constitute the sheet material 42 of leakproof pad 40 using bonding agent (not shown) also with back sheet 22 Skin opposite face engagement.
Fig. 4 (b) such as Fig. 4 (a) enlarged view of the main part is shown, side absorbent body 23d non-skin opposite face The junction surface 43 of the above-mentioned bonding agent 40a formation of utilization in side not side absorbent body 23d width Y whole region shape Into, and the region (below, is referred to as " engaging zones 43a " by formation in bias in the region of opening 231a sides.).Than bonding land Domain 43a is by the region not applied adhesives 40a of width Y foreign side, and positive dough sheet 21 extends position 21E and constitute leakproof shield The region (below, is referred to as " non-set out region 43b " by the sheet material 42 for enclosing 40 as disengaged condition.).So, in side absorbent With respect to surface side, in width Y, engaging zones 43a and disengaged area has been arranged side by side from interior direction foreign side in body 23d non-skin Domain 43b.
In the free end 40 ' of leakproof pad 40, i.e. in doubled state sheet material 42 broken line position, elastomeric element 41a is fixed in the sheet material 42 with elongation state.In addition, fixing end, i.e. sheet material 42 and back sheet 22 in leakproof pad 40 Bonding station, elastomeric element 41b is fixed in the sheet material 42 with elongation state.Shunk, made by these elastomeric elements 41a, 41b Obtain in the state of wearing diaper 10, leakproof pad 40 is erected towards the body of wearer.
Fig. 5 represents the width profile under the wearing state of the diaper 10 shown in Fig. 1 to Fig. 4.As shown in the drawing, exist In the absorbent core 23 of diaper 10, side absorbent body 23d in the absorbent core 23 utilizes the contraction of elastomeric element 25 ', with by The curved guide portion that the 231a that is open is formed is starting point, is bent in the way of being separated from exterior body 30.In this case, exist In the curved guide portion formed by opening 231a, covering piece 24 of the skin with respect to the surface side relative with non-skin of covering piece 24 of surface side When being engaged by joint methods such as bonding agents, the bending of the side absorbent body 23d by starting point of the curved guide portion is successfully sent out It is raw.As a result, the bending in the undesirable position of absorbent core 23 can be prevented effectively.
Using curved guide portion as starting point, in the case that side absorbent body 23d bends to the body of wearer, on Side absorbent body 23d, it is not similarly to bend that it is overall, and the degree of bending is according to width Y position difference It is different.Specifically, in side absorbent body 23d position corresponding with the engaging zones 43a shown in above-mentioned Fig. 4 (b) and with it is non- The corresponding positions of engaging zones 43b, the degree of the bending on the basis of central absorbent body 23c is different.Its reason is as described below.Such as Upper described, on side absorbent body 23d, in its non-skin abutment face side, the position 21E that extends of positive dough sheet 21 is protected with constituting leakproof Enclose the engagement position of 40 sheet material 42 at junction surface 43.Under the engagement state, side absorbent body 23d using curved guide portion as rise When point bends, due to above-mentioned engagement, the bending at position corresponding with engaging zones 43a is limited in side absorbent body 23d System, side absorbent body 23d between its width Y elastomeric element 25 ' and junction surface 43, i.e. with 43b pairs of non-set out region The position answered preferentially bends.
According to the reasons why the above, as shown in figure 5, side absorbent body 23d bends change relative to central absorbent body 23c Shape, and side absorbent body 23d itself sends out in the way of being upwardly formed substantially L-shaped in the side protruding outside to width Raw bending.Bent by the such two benches of absorbent core 23, in the diaper 10 of present embodiment, in its wearing state Under, even if intensely being opened because of the action of wearer, particularly be frequently observed in low monthly age youngster rapid and closing up pin Action and apply excessive external force to absorbent core 23, can also stably be maintained in the skin of diaper 10 in respect to surface side Space that centre absorber 23c and side absorbent body 23d is formed, i.e. stably maintenance width and height.As a result, can be with The containment of excreta is improved, and can effectively prevent the side leakage of accommodated excreta.
In particular, in the present embodiment, surface side is being provided with leakproof pad 40 by non-skin than absorber 25 Fixing end, therefore, have and promote the side absorbent body 23d such advantage of two benches bending using erecting for leakproof pad 40. Particularly as shown in Figure 4 and Figure 5, the fixing end of leakproof pad 40 is located at extends position 21E with constituting leakproof than positive dough sheet 21 When width Y foreign side is more leaned at the junction surface 43 of the sheet material 42 of pad 40, further it can promote side absorbent body 23c substantially The flexural deformation of L-shaped, thus be favourable.Furthermore, match somebody with somebody in the fixing end of leakproof pad 40 or the position near it When being equipped with elastomeric element 41b, it can further promote the substantially L-shaped of the side absorbent body 23d erected using leakproof pad 40 Flexural deformation, thus particularly preferably.
