Fig. 6 is with the partly enlarged top view in the region surrounded the single dotted broken line VI of Fig. 2, and Fig. 7 is that diaper 10 wears shape
The perspective view obtained from the side of the back side under state.In figure 6 and figure 7, only to the side on the lateral X for being located at absorber 51
Buttocks cover portion 78 be illustrated, but be located at the other side buttocks cover portion 78 also have same structure.In Fig. 7, indicate
In order to make the form of the buttocks cover portion 78 under wearing effect explicitly with reference to figure.
Referring to figure 6 and figure 7, it is formed at buttocks corresponding region 75 in the two sides of absorber 51 and elastomer is corresponded to by buttocks
76, the convergent force of each elastomer or each elastomer of most inner side rear waist elastic body 80 and the 2nd rib collar elastomer 57b
The buttocks cover portion 78 that each Hookean region acted on surrounds.Buttocks cover portion 78 is under wearing effect with 81 phase of buttocks with wearer
Pair mode determine position, surrounded by the region entirety that soft sheet element is formed by each elastomer, therefore be in swollen outward
Such form out.Herein, for common disposable shorts, due to the movement etc. in the wearing process of wearer, crotch
The central portion 13C in portion region 13 is pulled to groin or its part is sandwiched in and in gluteal fold and is likely to result in one of buttocks
Divide and is exposed to outside.In particular, front waist region 11, rear waist region 12 are formed by sheet material independent, it is so-called
Three pieces construction diaper, easily cause the situation, and there is the buttocks of the buttocks for preventing the covering of the situation from exposing
The diaper of piece is well known.However, the hips are the pieces for coating the buttocks for having been exposed to outside, rather than it is used for
Prevent the piece of exposure of buttocks itself.
Referring to (b) of Fig. 7, in the present embodiment, buttocks cover portion 78 is in a manner of coating 81 entirety of buttocks in outward
The such form of bulging, therefore even if due to wearer movement, delimit buttocks cover portion 78 buttocks correspond to elastomer 76 with/
Or the 2nd rib collar elastomer 57b it is close by the central portion 13C layback to crotch region 13, as represented by the imaginary line with (b) of Fig. 7
As, the part of bulging outward has been stretched the amount for being equivalent to and having been furthered, and becomes the state for fitting in buttocks 81, therefore
It will not lead to the leg opening edge reduced amplitude of rear side and make the exposure of buttocks 81.Thus, it is possible to prevent because buttocks 81 is from diaper 10
The leakage of sense of discomfort, excreta caused by exposure.In particular, in the diaper 10 of present embodiment, in crotch region 13
Centre portion 13C is formed by the piece of single layer, therefore is sandwiched between the crotch of wearer and is deformed, and buttocks corresponds to elastomer 76 and is easy as a result,
It is stretched downwards, the effect can be played.
In addition, in general, the region existing for absorber 51, diaper are possible to lead in the such form of bulging outward
It causes the case where it is diaper that appearance, which can visually readily recognize as this, but in the present embodiment, by soft sheet element
The buttocks cover portion 78 of formation passes through in the such form of bulging outward, can make the back side entirety bulging of diaper and assign soft
Impression as soft personal clothing.In particular, present embodiment applies pressure in the outer surface of front waist piece 26, rear waist piece 27
Flower/Shen Hua Jiagong and further increase flexibility, therefore can assign and be easy bulging outward and fluffy soft impression, and
And there can be appearance as personal clothing using the embossing/Shen flower decorative pattern 28.
Formed buttocks cover portion 78 each Hookean region in, the elongation stress of the preset width in hip resilient portion 77 and by
The elongation stress of the preset width for the Hookean region that 2nd rib collar elastomer 57b is formed is set to than comprising rear waist elastic body
The preset width of the rear inner elastic region 73c for being located at the most inner side rear waist elastic body 80 near 13 side of crotch region in 74
Elongation stress it is low.Specifically, in each rear waist elastic region 73a, 73b, 73c, on the outside of the lateral X of absorber 51
The elongation of preset width (30mm width) at position when being 171% (when size under natural conditions is set as 100%
171% size) elongation stress for, rear inner elastic region 73c is about 3.0N~8.0N, and hip resilient portion 77 is about
0.5N~5.0N, the elongation by the preset width of the 2nd rib collar elastomer 57b of the leak-proof cuff Hookean region formed are 171%
When elongation stress be about 1.0N~5.0N, and the correlativity of elongation stress is, rear inner elastic region 73c > by the 2nd sieve
Hookean region >=hip resilient portion 77 that mouth elastomer 57b is formed.
In order to make buttocks cover portion 78, bulging outward is excellent to tighten buttocks with being packed in buttocks and not stronger degree fluffyly
Choosing is that the elongation stress for each Hookean region for delimiting buttocks cover portion 78 is set as relatively low, but it is preferred that protecting steadily
The region for holding the waistline of (hold) wearer has required elongation stress.In the present invention, the elongation stress of each Hookean region
For the correlativity, for keeping the region of the waistline of wearer, particularly with needing most the ilium being held stably
The rear inner elastic region 73c that locating position abuts against has required elongation stress and can be effectively prevented and wear shape
Diaper offset is glided under state, and by being set to the elongation stress of other Hookean regions than the rear inner elastic region 73c
Elongation stress it is low, not will lead to and assign sense of discomfort as caused by tightening etc..
In addition, the rake 76b that buttocks corresponds to elastomer 76 has a bending, thus can transversely X and longitudinal direction Y (or
Person is comprehensive) it is flexible.Thus, compared with the case where buttocks corresponds to the linearly transversely X extension on the whole of elastomer 76, when it
Stretched downwards and buttocks cover portion 78 become it is flat when, buttocks cover portion 78 can be made similar with the shape of the buttocks with wearer
Mode to four directions elongation and fit in body.In addition, the contemplated function as buttocks cover portion 78, it is contemplated that pumping function,
That is: for example, due to wearer movement, delimit buttocks cover portion 78 the 2nd rib collar elastomer 57b with absorber 51 mobile linkage
Ground stretches or buttocks to correspond to elastomer 76 flexible, so that buttocks cover portion 78 is shunk repeatedly, is expanded, make at this time the air of outside from
Rivel (leg rivel) that elastomer 76 is formed is corresponded to relative to entering in buttocks cover portion 78, exiting, to prevent from urinating by buttocks
It is sultry in cloth 10.
The elongation stress of 2nd rib collar elastomer 57b is lower than the elongation stress of the 1st rib collar elastomer 57a.2nd rib collar elasticity
Body 57b utilizes the front waist elastomer 72 intersected with it and the corresponding elastomer 76 of buttocks to be formed for around leg opening edge
Imaginary elastic webbing, but correspond to the part that elastomer 76 rearward extends from buttocks and played for assisting the standing of leak-proof cuff
Function does not need relatively high elongation stress.Thus, the 1st rib collar elastomer 57a has the amphi position edge for making leak-proof cuff
Portion 52a erects and plays the relatively high elongation stress of sufficient drip-preventing function, as long as and the 2nd rib collar elastomer 57b has
The relatively low elongation stress that the degree of buttocks cover portion 78 can be formed is just enough, and the elongation for being able to suppress leak-proof cuff entirety is answered
Power is excessively high and tightens body.In addition, in the 2nd rib collar elastomer 57b, outermost rib collar elastomer 58 on the outermost side when overlooking
It is configured at the non-domain of the existence of absorber 51, therefore the rigidity of absorber 51 will not be overcome and shunk, therefore, even relatively
Low elongation stress, which can be also punctured into, makes substrate 25 and rear waist piece 27 be capable of forming the degree of buttocks cover portion 78.
Buttocks cover portion 78 needs to make buttocks cover portion to become bulging outward to the form for the degree for coating buttocks entirety
The surface area of 78 entirety is relatively large, but in the present embodiment, and the size on longitudinal Y in buttocks cover portion 78 is usual with other
Used diaper, which is compared, greatly, therefore to have relatively large surface area.Specifically, the maximum longitudinal direction of buttocks cover portion 78
(the straight part 76a's of the elastomer 76 corresponding with buttocks of most inner side rear waist elastic body 80 separates size to size on Y.Reference
Fig. 6.) L3 have rear waist region 12 rear side edge 12b, 12c longitudinal Y on size L2 about 60%~80% it is big
It is small.
In addition, buttocks corresponds to elastomer 76 and most inner side rear waist elastic body 80 in the two sides edge of rear waist region 12
(rear waist elastic body 74) separates on longitudinal Y, does not cross one another when looking down.By intersecting these elastomers not, buttocks
Contraction of the corresponding elastomer 76 not directly by rear waist elastic body 74 towards waistline direction is influenced, thus itself
Leg opening edge can be made to fit in body under contraction, and the Curved of elastomer 76 can be corresponded to using the buttocks
Shape forms the buttocks cover portion 78 of bending convex.In order to generate the effect, it is preferred that after the most inner side of rear side edge 12a, 12b
The size R3 that separates between the elastomer 76 corresponding with buttocks of waist elastics 80 on longitudinal Y is about 100mm~180mm.This is
Because in the case where separated size R is less than about 100mm, it is possible to the convergent force of elastomer 80 be caused to correspond to bullet to buttocks
Property body 76 impact, separated size R3 be more than about 200mm in the case where, between rake 76b and elastomer 80
Inelastic region becomes larger, it is possible to which leading to the stickiness of the waist relative to wearer reduces.
It is set as in addition, buttocks corresponds to the separated size (spacing) between elastomer 76 than in rear inner elastic region 73c
Rear waist elastic body 74 between separated size it is small.Hookean region comprising most inner side rear waist elastic body 80 is capable of forming logical
Crossing makes to separate the big band of relatively large sized and the waistline that can steadily fit in wearer width between each elastomer
Shape Hookean region, on the other hand, by keeping the width dimensions in hip resilient portion 77 relatively small, can make hip resilient portion 77 with
Leg opening fate opens intended size.
