In the absorbent commodity 1 of present embodiment, the length W1 of the center of the fore-and-aft direction L at territory, pterion CA of absorber 30 is larger than the length W2 on the width W in forefoot area FA and rear region BA of this absorber 30.Thus, according to this absorbent commodity, due to comparing with the greatest length WA situation little with WB on width in rear region BA at forefoot area FA of this absorber of Length Ratio on the width of the center of the fore-and-aft direction L at territory, pterion CA with absorber,, with the absorbent commodity that the mode of the inboard depression of width of mind-set absorber in the fore-and-aft direction in territory, pterion with at absorber forms, compare, the intensity to width W inboard of absorbent commodity 1 raises, and therefore can suppress to result from the fold at the fore-and-aft direction L center of territory, pterion CA.

At this, in (a) of Fig. 5, meaned when the absorbent commodity of fixing prior art, because near the power of the shank hip thigh acts on the schematic diagram of the state of strong F to the inboard on width W, in (b) of Fig. 5, meaned when the absorbent commodity of fixing present embodiment, because near the power of the shank hip thigh acts on the schematic diagram of the state of strong F to the inboard on width W.In addition, Fig. 5 (a) is the cutaway view that the X-X line of take shown in Fig. 1 is benchmark to (b) of Fig. 5.

In the absorbent commodity of prior art, with length W1 on the width of absorber of the center of the fore-and-aft direction L at territory, pterion CA that protuberance 31 is not set correspondingly is configured to absorber, be equal to or less than greatest length W2A and the W2B on the width in forefoot area FA and rear region BA of this absorber.In this absorbent commodity, as shown in Fig. 5 (a), when the stressed F that is subject to towards the inboard of width W, do not there is protuberance 31 with absorber 30 and correspondingly make absorber 30 towards the inboard of width W, cause absorber 30 to the inboard fold of width W.Thus, the fold produced on the absorber of territory, pterion CA is delivered to forefoot area FA and rear region BA and causes the absorber in forefoot area FA and rear region BA also to produce fold simultaneously.So, because the fold produced in the CA of territory, pterion causes being not only territory, pterion CA, even the absorber in forefoot area FA and rear region BA also produces fold, therefore produce leakage of body fluids is arranged.

On the other hand, as shown in Fig. 5 (b), in the absorbent commodity 1 in present embodiment, absorber 30 has protuberance 31, so protuberance 31 can be towards the inboard absorbing power F of width W.Thus, can suppress in the fore-and-aft direction L center of territory, pterion CA the fold that the inboard on width W produces.And, by the fold at CA place, territory, pterion of decrease uptake body 30, can suppress also to produce the situation of fold because this fold causes absorber in forefoot area FA and rear region BA.Thereby, according to this absorbent commodity 1, not only can suppress to result from the fold at the CA place, territory, pterion of absorber 30, also can prevent the fold in forefoot area FA and rear region BA of absorber, therefore can improve the leakage of body fluids caused because of fold.

And, can suppress for a long time to result from the fold of fore-and-aft direction L center of territory, the pterion CA of present embodiment.Thereby, even cause the service time of absorbent commodity longer in the situation that emerging nation etc. can't change absorbent commodity for several times on 1st because of the situation of economic situation, custom, also can suppress to result from the fold on absorbent commodity, can improve the leakage of body fluids caused because of fold.

Length W1 on the width W of the center of the fore-and-aft direction L at territory, pterion CA of absorber 30 is larger than the length W2 on the width W of the end in the fore-and-aft direction L at territory, pterion CA of this absorber 30 outside.

Specifically, the center of absorber 30 on the fore-and-aft direction L of territory, pterion CA has the protuberance 31 protruded to the width W outside.Thus, the center on the fore-and-aft direction L of territory, pterion CA, the intensity to width W inboard of absorbent commodity 1 raises, thereby can suppress reliably fold.At this, usually, when attaching absorbent articles 1, the fore-and-aft direction L center of territory, pterion CA at least is positioned at the scavenge port butt zone of the body fluid scavenge port that is connected to the wearer.Thus, the fold of the fore-and-aft direction L center by suppressing reliably to result from territory, pterion CA, can further improve the leakage of body fluids caused because of fold.

In addition, method as the intensity to width W inboard that improves absorbent commodity 1, also consider to have the method that the width of absorber 30 is integrally expanded to width W, but make the wearer produce sense of discomfort because the easy lower limb the wearer encloses place, therefore not preferred.Particularly forefoot area FA is the many especially zones of motion that wearer's lower limb encloses place.Thereby, if the length on the width W in the CA of territory, pterion of this absorber 30 of Length Ratio on the width W in forefoot area FA of absorber 30 is large, be easy to produce friction with wearer's lower limb root place, therefore be easy to make the wearer to produce sense of discomfort.

In addition, in the absorbent commodity of prior art, usually, when wearer movement, be easy to cause the leakage of body fluids from width W, in the situation that long-time, use and just can arrive the allowance of the body fluid of absorber very soon.In the absorbent commodity 1 of present embodiment, increase the amount that is provided with the protuberance 31 protruded to the width W outside by the volume that makes absorber 30, thereby can improve the allowance of body fluid, can prevent leakage of body fluids.In addition, because the allowance of body fluid is larger, therefore also can when the wearer sees absorbent commodity 1, give the wearer and feel at ease to feel.

In addition, by being provided with protuberance 31 and making it to width W expansion, when attaching absorbent articles, protuberance 31 fits near the hip thigh, thereby prevents from producing space between near absorber 30 and hip thigh.In addition, because the wearer can feel the existence of absorber 30 near the hip thigh, therefore can make the wearer produce and feel at ease to feel.In addition, owing to being provided with protuberance 31, therefore, when being fixed on underwear by absorbent commodity 1, protuberance 31 forms labelling, and user is easy to hold fixed position.Thus, absorbent commodity can be fixed in to correct position, thereby be difficult to occur the skew of fixed position.

In addition, preferably, center configuration on the fore-and-aft direction L of the protuberance 31 of absorber 30 is in the roughly the same position, fore-and-aft direction L Shang center with

alar part

43,44, and the length on the fore-and-aft direction L of the length L 31 on the fore-and-aft direction L of protuberance and

alar part

43,44 is identical or below it.

Consistent by the position on the fore-and-aft direction L of the position on the fore-and-aft direction L that makes protuberance 31 and

alar part

43,44, can when attaching absorbent articles 1, bring into play to greatest extent and be difficult to make absorber 30 to produce the effect of folds.The power of pressing to the width inboard applied by wearer's lower limb is applied in territory, whole pterion.If too short the length of the length on the fore-and-aft direction L of protuberance 31 on the fore-and-aft direction L of

alar part

43,44, can't absorb the stressed of inboard on width W fully.On the other hand, if long the length of the length on the fore-and-aft direction L of protuberance 31 on the fore-and-aft direction L of

alar part

43,44, not only be easy to make the wearer produce sense of discomfort, before and after stressed being delivered to due to the inboard on width W, therefore make absorbent commodity 1 integral body be easy to form fold.

In addition, a pair of compression groove 80 is larger at the interval of the end in the fore-and-aft direction L outside of territory, pterion CA to each other than a pair of compression groove 80 at the interval of the fore-and-aft direction L center of territory, pterion CA to each other.That is,, in the center of the fore-and-aft direction L of territory, pterion CA, compression groove 80 is configured to the outside expansion to width W.

Specifically, compression groove 80 comprises inboard compression groove 81 and is configured in the outside compression groove 82 by the width outside than inboard compression groove 81.In addition, the interval W4 in the fore-and-aft direction L center of territory, pterion CA is larger at the interval W5 to each other of the end in the fore-and-aft direction L outside of territory, pterion CA than this pair of outside compression groove 82 to each other for pair of outside compression groove 82.

At this, the absorber 30 also center on the fore-and-aft direction L of territory, pterion CA has the protuberance 31 protruded to the width W outside.In addition, outside compression groove 82 is configured in the center of the fore-and-aft direction L of territory, pterion CA to be expanded to the outside of width W, thereby outside compression groove 82 forms along the such structure of shape of the protuberance 31 of absorber 30.So, by compression groove 80 being configured to along the shape of the protuberance 31 of absorber 30, thereby in the center of the fore-and-aft direction L of territory, pterion CA, the intensity to width W inboard of absorbent commodity 1 is raise, therefore can suppress to result from the fold of the fore-and-aft direction L center of territory, pterion CA.

In addition, in the present embodiment, as the compression groove 80 of the fore-and-aft direction center of territory, pterion CA, comprise inboard compression groove 81 and be configured in the outside compression groove 82 by the width outside than inboard compression groove 81.Thus, owing to utilizing inboard compression groove 81 and the such double groove of outside compression groove 82 that compression groove is set, therefore be difficult to produce distortion at the inboard place of the width W of inboard compression groove 81, therefore can suppress to result from the fold of the fore-and-aft direction L center of territory, pterion CA.

In addition, preferably, the length L 31 on the fore-and-aft direction L of the protuberance 31 of absorber 30 is shorter than the length L a on the fore-and-aft direction L of inboard compression groove 81.Because the length L 31 on the fore-and-aft direction L by making protuberance 31 is shorter than the length L a on the fore-and-aft direction L of inboard compression groove 81, and make from the width W outside to inboard power to be absorbed by inboard compression groove 81 and outside compression groove 82 these two grooves 2, therefore increased and suppressed to the effect of the fold of width W.

According to present embodiment, at least one of inboard compression groove 81 and outside compression groove 82 is continuous ring-type.Thus, guaranteed the rigidity in the zone of width W inboard of inboard compression groove 81 and outside compression groove 82, fold that therefore can decrease uptake body 30.

In forefoot area FA and/or rear region BA, the weight per unit area at the sidepiece place of the width W of absorber 30 is larger than the weight per unit area of the centre of the width W of this absorber 30.

Specifically, as shown in Figure 4, the weight per unit area of SF2 or SF3 is larger than the weight per unit area of SF1.In addition, the weight per unit area of SB2 or SB3 is larger than the weight per unit area of SB1.

Thus, in forefoot area FA and rear region BA, the rigidity at the sidepiece place on width W is set to higher than the rigidity of the centre on width W, and near the power of the shank hip thigh while therefore being difficult to because of attaching absorbent articles 1 produces fold in the inboard of width W.In addition, even producing, the inboard of absorber 30 on width W of hypothesis territory, pterion CA have fold, this fold also to be difficult to the absorber 30 direction L transmission forwards, backwards by territory, pterion CA.Its result, be difficult to produce fold in forefoot area FA and rear region BA.In addition, even in the situation that the long-time absorbent commodity that uses also can suppress to result from the fold on absorbent commodity.

In forefoot area FA and/or rear region BA, the weight per unit area at the sidepiece place on the width W of absorber 30 is larger than the weight per unit area at the sidepiece place on the width of territory, the pterion CA of this absorber 30.Specifically, as shown in Figure 4, the weight per unit area of SF2 or SF3 is larger than the weight per unit area of SC2 or SC3.

Thus, the weight per unit area of the absorber 30 at the sidepiece place by increasing forefoot area FA and/or rear region BA, can absorb with the part that has increased weight per unit area the power be subject to from the width direction, the absorbing surface at center can be remained to plane.In addition, even suppose in the situation that produce fold is arranged on the absorber 30 in the CA of territory, pterion, fold also is difficult to the sidepiece transmission from the sidepiece of the absorber 30 in the CA of territory, pterion to forefoot area FA and/or rear region BA, therefore can suppress the fold of the absorber of forefoot area FA and/or rear region BA.

Be formed with a plurality of point-like compression units 90 in forefoot area FA and rear region BA.Specifically, a plurality of point-like compression units 90 form the state of dispersion.

Thus, guaranteed the rigidity on plane on the absorber 30 in forefoot area FA and rear region BA, made the absorber 30 in forefoot area FA and rear region BA more be difficult to produce fold.Thereby, even, in the situation that the service time of absorbent commodity is longer, also can suppress to result from the fold of absorbent commodity.In addition, by forming point-like compression unit 90, with the situation that forms compression groove, compare, can improve breathability.
