[發明所欲解決之課題][Problems to be Solved by the Invention]

可是，拋棄時的吸收性物品，是吸收體液，且與使用前比較其厚度厚。因此，將吸收性物品朝前後方向團化時，很難緊緻地予以團化。因此，會有不能使用帶片構件在吸收性物品團化的狀態下作固定的情況。However, the absorbent article when discarded absorbs body fluids and is thicker than before use. Therefore, when the absorbent article is agglomerated in the front-rear direction, it is difficult to agglomerate tightly. Therefore, there is a case where the belt member cannot be fixed in a state where the absorbent article is agglomerated.

[實施發明用的形態][Form for Implementing Invention]

(1)實施形態的概要
根據本說明書及添附圖面的記載，至少明白以下的事項。(1) Outline of Embodiments At least the following matters are understood from the description of this specification and the drawings.

使用者在拋棄時從第2區域側將吸收性物品團化，而藉由帶片構件將團化後的狀態的吸收性物品作固定。此時，因為團化後的狀態下，位於內側的第2區域的彎折基點部的平均間隔短，所以可緊緻地作團化。又，因為團化後的狀態下，在位於外側的第1區域也設有複數個彎折基點部，所以，第1區域及第2區域皆可容易地團化，且容易維持團化後的狀態。因此，將吸收性物品維持於緊緻的團化後的狀態，而可藉由後處理用的帶片構件清潔地進行廢棄。When the user discards the absorbent article from the second area side, the absorbent article in a state of being agglomerated is fixed by the belt member. At this time, since the average interval between the bending base point portions of the second region located on the inner side is short after the spheroidization, the spheroidization can be performed tightly. In addition, since a plurality of bending base point portions are also provided in the first region located outside in the state after the grouping, both the first region and the second region can be easily grouped and it is easy to maintain the group after the grouping. status. Therefore, the absorbent article is maintained in a tight and compacted state, and can be discarded cleanly by the belt member for post-processing.

根據理想的一態樣，其中，前述第2區域的前述彎折基點部的數量較前述第1區域的前述彎折基點部的數量更多。According to an ideal aspect, the number of the bending base point portions in the second region is larger than the number of the bending base point portions in the first region.

根據一態樣的吸收性物品，其中，因為團化後的狀態下，在位於內側的第2區域中彎折基點部的數量多，所以，在團化後的狀態的內側形成有許多個變形基點，而更容易緊緻地團化。According to an aspect of the absorbent article, since the number of the base point portions is large in the second region located on the inner side in the state after the grouping, many deformations are formed on the inner side of the state after the grouping. The base point is more easily compacted.

使用者在拋棄時從第2區域側將吸收性物品團化，而藉由帶片構件將團化後的狀態的吸收性物品作固定。此時，團化後位於外側的第1區域在團化後的狀態下沿著位於內側的部分被捲起。因為第1區域的彎折基點部的平均間隔短，所以可將團化後的狀態下位於外側的第1區域用短的間隔彎折。因此，將第2區域團化後的狀態下，即使在外面形成凹凸，也容易將第1區域團化成圓形狀。又，因為團化後的狀態下在位於內側的第2區域也設有複數個彎折基點部，所以，第1區域及第2區域皆可藉由彎折基點部容易緊緻地團化，且容易維持團化後的狀態。因此，將吸收性物品維持在團化後的狀態，而可藉由後處理用的帶片構件清潔地進行廢棄。When the user discards the absorbent article from the second area side, the absorbent article in a state of being agglomerated is fixed by the belt member. At this time, the first area located on the outside after being agglomerated is rolled up along the portion located on the inside in a state after being agglomerated. Since the average interval of the bending base point portions in the first region is short, the first region located on the outer side in the state after being agglomerated can be bent at a short interval. Therefore, in a state where the second region is clustered, even if irregularities are formed on the outside, the first region is easily clustered into a circular shape. In addition, since the plurality of bending base point portions are also provided in the second region located on the inner side in the state after the grouping, both the first region and the second region can be easily and tightly grouped by the bending base point portions. And it is easy to maintain the state after the grouping. Therefore, the absorbent article is maintained in a state after being agglomerated, and can be discarded cleanly by the belt member for post-processing.

根據理想的一態樣，其中，前述第1區域的前述彎折基點部的數量較前述第2區域的前述彎折基點部的數量更多。According to an ideal aspect, the number of the bending base point portions in the first region is larger than the number of the bending base point portions in the second region.

根據其他的態樣的吸收性物品，其中，因為團化後的狀態下，在位於外側的第1區域中彎折基點部的數量多，所以，在團化後的狀態的外側形成有許多個變形基點，而更容易維持緊緻的團化狀態。According to another aspect, the absorptive article has a large number of bending base points in the first region located on the outer side in the state after being grouped, and therefore, many are formed on the outer side of the state after being grouped. Transform the base point, and it is easier to maintain a tight mass.

根據理想的一態樣，其中，前述第1區域相對於前述前後方向的中心位於後側。According to an ideal aspect, the first region is located on a rear side with respect to a center of the front-rear direction.

使用者通常將吸收性物品團化時，從吸收性物品的前端緣或後端緣朝前後方向開始團化。這之中，約8成的使用者，是從吸收性物品的前端緣開始團化。因此，帶片構件被設在相對於前後方向的中心位於後側的區域為理想。When a user aggregates an absorbent article, it starts from the front-end edge or the rear-end edge of an absorbent article, and it starts to agglomerate to a front-back direction. Among them, about 80% of the users started from the front edge of the absorbent article. Therefore, it is desirable that the belt member is provided in a region located on the rear side with respect to the center of the front-rear direction.

根據理想的一態樣，其中，前述第1區域的前述寬邊方向的最大長度較前述第2區域的前述寬邊方向的最大長度更長。According to an ideal aspect, the maximum length in the wide-side direction of the first region is longer than the maximum length in the wide-side direction of the second region.

因為團化後的狀態下，位於外側的第1區域的寬邊方向的最大長度長，所以，可藉由位於外側的第1區域覆蓋團化後的狀態下，位於內側的第2區域，而成為更容易維持團化後的狀態。Since the maximum length in the wide-side direction of the first region located outside is long in the state after clustering, the second region located inside can be covered by the first region located outside to cover the second region located inside. It becomes easier to maintain the state after the grouping.

根據理想的一態樣，其中，前述彎折基點部至少包含朝厚度方向壓榨前述吸收芯的壓榨部。According to an ideal aspect, the bending base point portion includes at least a pressing portion that presses the absorbent core in a thickness direction.

壓榨部與沒有形成壓榨部的區域比較剛性高且厚度薄。藉由該壓榨部構成彎折基點部，根據厚度差及剛性差容易將吸收性物品緊緻地團化。The press section is more rigid and thinner than the area where the press section is not formed. By forming the bending base point portion by the press portion, the absorbent article can be easily and tightly grouped in accordance with the difference in thickness and rigidity.

根據理想的一態樣，其中，前述壓榨部從肌膚對置面側朝向非肌膚對置面側凹陷。According to an ideal aspect, the pressing part is recessed from the skin-facing surface side toward the non-skin-facing surface side.

使用者一般來說在拋棄時，將附著***物的肌膚對置面側作為內側，將吸收性物品團化。因為壓榨部從肌膚對置面側朝向非肌膚對置面側凹陷，所以，容易使肌膚對置面側接近地變形，而形成以肌膚對置面側為內側容易將吸收性物品團化。In general, when a user discards, the side of the skin-facing surface on which the fecal matter adheres is used as an inner side, and the absorbent article is agglomerated. Since the pressing portion is recessed from the skin facing surface side toward the non-skin facing surface side, it is easy to deform the skin facing surface side close, and it is easy to agglomerate the absorbent article with the skin facing surface side as the inside.

根據理想的一態樣，其中，前述彎折基點部在前述前後方向包含相對於鄰接的區域，前述吸收芯的吸收材料的基重不同的基重變化部。According to an ideal aspect, the bent base point portion includes a basis weight change portion having a different basis weight of the absorbent material of the absorbent core with respect to the adjacent region in the front-rear direction.

基重變化部與和前後方向鄰接的區域吸收材料的基重不同，吸收芯的厚度及剛性不同。藉由該基重變化部構成彎折基點部，根據厚度差及剛性差容易將吸收性物品緊緻地團化。The basis weight change portion has a different basis weight from that of the absorbent material in a region adjacent to the front-back direction, and the thickness and rigidity of the absorbent core are different. By forming the bent base point portion by the basis weight change portion, the absorbent article can be easily and tightly grouped in accordance with the difference in thickness and rigidity.

根據理想的一態樣，其中，前述基重變化部相對於和前述前後方向鄰接的區域為基重低的低基重部，
前述低基重部沿著寬邊方向被設置，
在沿著前述前後方向的剖面觀看，前述低基重部的肌膚對置面的前述前後方向的長度較前述低基重部的非肌膚對置面的前述前後方向長度更長。According to an ideal aspect, the basis weight change portion is a low basis weight portion having a low basis weight relative to a region adjacent to the front-back direction,
The aforementioned low basis weight portion is provided along the wide side direction,
When viewed in a cross section along the front-rear direction, the length of the front-rear direction of the skin-opposing surface of the low-basis-weight portion is longer than the length of the front-rear direction of the non-skin-facing surface of the low-basis portion.

使用者一般來說在拋棄時，將附著***物的肌膚對置面側作為內側，將吸收性物品團化。因為低基重部的肌膚對置面的前後方向的長度較低基重部的非肌膚對置面的前後方向的長度更長，所以，容易使肌膚對置面側接近地變形，而形成以肌膚對置面側為內側容易將吸收性物品團化。In general, when a user discards, the side of the skin-facing surface on which the fecal matter adheres is used as an inner side, and the absorbent article is agglomerated. Since the length of the front-back direction of the skin-facing surface of the low-basis portion is lower than that of the non-skin-facing surface of the base-weight portion, the length of the front-back direction is longer. The skin facing side is on the inside to easily agglomerate the absorbent article.

根據理想的一態樣，其中，前述彎折基點部包含將前述吸收性物品的肌膚對置面以相對向的方式折疊的折痕。According to an ideal aspect, the bending base point portion includes a fold that folds a skin-facing surface of the absorbent article in a facing manner.

容易藉由折痕的折性使肌膚對置面側接近地變形，而形成容易以肌膚對置面側為內側將吸收性物品團化。It is easy to deform the skin facing surface side close by the foldability of the crease, and it is easy to agglomerate the absorbent article with the skin facing surface side as the inside.

根據理想的一態樣，其中，前述彎折基點部沿著前述寬邊方向延伸。According to an ideal aspect, the bent base point portion extends along the wide side direction.

將吸收性物品團化時的變形基點沿著寬邊方向延伸，而容易將吸收性物品的寬邊方向全域朝前後方向團化。The deformation base point when the absorbent article is agglomerated extends along the broad side direction, and it is easy to agglomerate the entire wide side direction of the absorbent article in the front-rear direction.

根據理想的一態樣，其中，前述彎折基點部具有：前述寬邊方向的長度較前述前後方向的長度更長的第1彎折基點部、以及前述前後方向的長度較前述寬邊方向的長度更長的第2彎折基點部，前述第1彎折基點部的數量較前述第2彎折基點部的數量更多。According to an ideal aspect, the bending base point portion includes a first bending base point portion having a length in the wide side direction longer than the length in the front-back direction, and a length in the front-back direction which is longer than the width-side direction. As for the second bending base point portion having a longer length, the number of the first bending base point portions is larger than the number of the second bending base point portions.

因為第1彎折基點部的數量較第2彎折基點部的數量多，所以，將吸收性物品團化時，相較於寬邊方向更容易朝前後方向團化。因此，容易將吸收性物品朝前後方向更緊緻地團化，而更容易維持團化後的狀態。Since the number of the first bending base point portions is larger than the number of the second bending base point portions, when the absorbent article is grouped, it is easier to group the absorbent article in the front-back direction than in the broad side direction. Therefore, it is easy to agglomerate the absorbent article more tightly in the front-rear direction, and it is easier to maintain the agglomerated state.

根據理想的一態樣，其中，前述彎折基點部在從前述第1區域中的前述本體部的前述前後方向的外端緣到前述本體部的前述前後方向的長度的1/3的範圍設置3個以上。According to an ideal aspect, the bending base point portion is provided in a range from 1/3 of an outer edge of the front-back direction of the main body portion in the first region to a length of the front-back direction of the main body portion. 3 or more.

將本體部朝前後方向團化後的狀態的周長，一般來說是形成相對於本體部的前後方向的長度為1/3左右。相對於本體部的前後方向的長度的1/3，是成為在團化後的狀態下位於外側的表面的部分。藉由在該部分設置3個以上的彎折基點部，而更容易維持團化後的狀態。In general, the perimeter of the state in which the main body portion is clustered in the front-rear direction is formed so that the length relative to the front-rear direction of the main body portion is about 1/3. One third of the length in the front-rear direction with respect to the main body portion is a portion that becomes the outer surface in a state after being agglomerated. By providing three or more bent base point portions in this portion, it is easier to maintain the state after the grouping.

如圖2所示，本體部20可具有設在裏面薄片22的非肌膚對置面側的黏著部52、70。黏著部52、70，是設有將吸收性物品10固定在穿著用物品的黏著劑的區域。黏著部可含有：本體黏著部70、以及翼片黏著部52。As shown in FIG. 2, the main body portion 20 may include adhesive portions 52 and 70 provided on the non-skin facing surface side of the back sheet 22. The adhesive portions 52 and 70 are regions provided with an adhesive for fixing the absorbent article 10 to a wearing article. The adhesive portion may include a body adhesive portion 70 and a flap adhesive portion 52.

藉由設在裏面薄片22的非肌膚對置面側的黏著部52、70，可將吸收性物品10固定在內褲等的穿著用物品。又，藉由黏著部52、70，在吸收性物品10的使用後，將吸收性物品10捲起的狀態下，將帶片構件60卡著而可維持捲著的狀態。因此，黏著部52、70可兼用在固定於穿著衣物的用途、與卡著後處理用的帶片構件的用途的2種。The adhesive portions 52 and 70 provided on the non-skin facing surface side of the back sheet 22 can fix the absorbent article 10 to wearing articles such as underwear. In addition, with the adhesive portions 52 and 70, after the absorbent article 10 is used and the absorbent article 10 is rolled up, the band member 60 is stuck and the rolled state can be maintained. Therefore, the adhesive parts 52 and 70 can be used for both the use which is fixed to a wearer, and the use which clamps a band member for post-processing.

本體黏著部70在吸收性物品10的厚度方向T，被設在與吸收芯23重疊的區域。本體黏著部70至少從***口對置域S1朝吸收性物品10的後方連續性或間斷性地延伸為理想。本體黏著部70朝前後方向L延伸，在寬邊方向W分開間隔設置複數個即可。其他的形態中，本體黏著部70朝寬邊方向W延伸，且可在前後方向分開間隔設置複數個。臀翼黏著部52被設在臀翼50。The main body adhesive portion 70 is provided in a region overlapping the absorbent core 23 in the thickness direction T of the absorbent article 10. The main body adhesive portion 70 preferably extends continuously or discontinuously from at least the excretory opening facing area S1 toward the rear of the absorbent article 10. The main body adhesive portion 70 may extend in the front-rear direction L, and a plurality of the adhesive portions 70 may be provided at intervals in the wide-side direction W. In other forms, the main body adhesive portion 70 extends in the wide-side direction W, and a plurality of the adhesive portions 70 may be provided at intervals in the front-rear direction. The hip wing adhesion portion 52 is provided on the hip wing 50.

吸收性物品10也可具有沿著寬邊方向W延伸的折痕。折痕可為將吸收性物品的肌膚對置面以面相對的方式作折疊的折痕。在圖1、2所示的例子，吸收性物品10的折痕具有：第1折痕F1、第2折痕F2、及第3折痕F3。第1折痕F1，是最接近吸收性物品10的前端緣E1的折痕。第2折痕F2，是最接近吸收性物品10的後端緣E2的折痕。第3折痕F3被配置在第1折痕F1與第2折痕F2之間。此外，折痕也可設置4條以上。折痕，是在吸收性物品的包裝時，以吸收性物品的肌膚對置面側T1為內側，折疊吸收性物品10用的線。The absorbent article 10 may have a crease extending along the broad side direction W. The crease may be a fold that folds the skin-facing surface of the absorbent article in a face-to-face manner. In the example shown in FIGS. 1 and 2, the crease of the absorbent article 10 includes a first crease F1, a second crease F2, and a third crease F3. The first crease F1 is a crease closest to the leading edge E1 of the absorbent article 10. The second crease F2 is a crease closest to the rear end edge E2 of the absorbent article 10. The third crease F3 is arranged between the first crease F1 and the second crease F2. In addition, four or more creases can be provided. The crease is a thread for folding the absorbent article 10 with the skin-opposing surface side T1 of the absorbent article as the inside when packaging the absorbent article.

帶片構件60被固定在本體部20的第1區域R1。帶片構件60，是如圖3所示，可具有被固定在本體部20的固定部62。固定部62可設在帶片構件60的一端。固定部62可藉由接著劑等的接著手段固定在本體部20。固定部62可固定在構成本體部20的非肌膚對置面的裏面薄片22。The band member 60 is fixed to the first region R1 of the main body portion 20. As shown in FIG. 3, the belt member 60 may include a fixing portion 62 fixed to the main body portion 20. The fixing portion 62 may be provided at one end of the belt member 60. The fixing portion 62 can be fixed to the main body portion 20 by an adhesive means such as an adhesive. The fixing portion 62 may be fixed to the back sheet 22 that is a non-skin-facing surface of the main body portion 20.

又，帶片構件60可具有沒有被固定在本體部20的非固定部64。非固定部64沒有被固定在裏面薄片22，且是使用者操作帶片構件60的部分。更詳細的是，使用者在使用帶片構件60時，拉非固定部64、或以固定部62為基點將非固定部64折返之後，將非固定部64卡著在本體部20。非固定部64可構成可在伸長方向伸長。非固定部64的伸長方向可為從固定部62朝向非固定部64的方向。固定部62與非固定部64在前後方向L鄰接的構成，則伸長方向可為前後方向L。於此，「伸長」，是包含「彈性變形」或「塑性變形」所致的伸長。就一例來說，帶片構件60可由伸縮性薄片、薄膜構成。The belt member 60 may include a non-fixed portion 64 that is not fixed to the body portion 20. The non-fixed portion 64 is not fixed to the back sheet 22 and is a portion where the user operates the belt member 60. More specifically, when the user uses the strap member 60, the user pulls the non-fixed portion 64 or returns the non-fixed portion 64 with the fixed portion 62 as a base point, and then clamps the non-fixed portion 64 to the main body portion 20. The non-fixed portion 64 may be configured to be stretchable in an elongation direction. The elongation direction of the non-fixed portion 64 may be a direction from the fixed portion 62 toward the non-fixed portion 64. When the fixed portion 62 and the non-fixed portion 64 are adjacent to each other in the front-rear direction L, the direction of elongation may be the front-rear direction L. Here, "elongation" includes elongation caused by "elastic deformation" or "plastic deformation". For example, the belt member 60 may be formed of a stretchable sheet or film.

帶片構件60的非固定部64也可設置暫時固定部(未圖示)。暫時固定部可剝離地接合在作為本體部20的非肌膚對置面的裏面薄片22。藉由設置暫時固定部，可抑制在帶片構件60的使用前(製造時、裝用時)，非固定部64捲曲、或非固定部64彎折的情況。暫時固定部的接合力可較固定部62的接合力更低。因為暫時固定部的接合力比固定部62的接合力更低，所以，使用者在帶片構件60的使用時容易剝離暫時固定部，而可抓住非固定部64操作帶片構件60。就暫時固定部的固定手段來說，可例示：接著劑、壓花加工、熱熔著、超音波熔著，而可比固定部62更減少接著劑的塗布量(面積、基重)、或可比固定部62更減弱壓花加工的壓榨。又，暫時固定部也可藉由本體部的外緣的壓花構成。The non-fixing portion 64 of the band member 60 may be provided with a temporary fixing portion (not shown). The temporary fixing portion is releasably joined to the back sheet 22 that is the non-skin-facing surface of the main body portion 20. By providing the temporary fixing portion, it is possible to prevent the non-fixed portion 64 from being curled or the non-fixed portion 64 from being bent before the tape member 60 is used (at the time of manufacture and installation). The engaging force of the temporary fixing portion may be lower than the engaging force of the fixing portion 62. Since the bonding force of the temporary fixing portion is lower than the bonding force of the fixing portion 62, the user can easily peel off the temporary fixing portion when using the strap member 60, and can grasp the non-fixing portion 64 to operate the strap member 60. Examples of the fixing means of the temporary fixing part include adhesives, embossing, thermal fusion, and ultrasonic fusion. The application amount (area, basis weight) of the adhesive can be reduced more than the fixed part 62, or comparable. The fixing portion 62 further weakens the pressing of the embossing process. The temporary fixing portion may be formed by embossing the outer edge of the main body portion.

帶片構件60，是吸收性物品10的拋棄時，卡著在以吸收性物品的肌膚對置面側為內側捲起的狀態的本體部20上，而構成維持捲起吸收性物品10狀態。帶片構件60的非固定部64構成相對於本體部20可卡著。非固定部64卡著在本體部20的結構，也可是本體部20的黏著部，也可是設在帶片構件60的黏著劑、鉤構件等的卡著手段。又，帶片構件60的固定部62也可構成相對於本體部20可卡著。固定部62卡著在本體部20的結構，也可是本體部20的黏著部，也可是設在帶片構件60的黏著劑、鉤構件等的卡著手段。The belt member 60 is configured to maintain the rolled up absorbent article 10 while being stuck on the body portion 20 in a state where the absorbent article 10 is rolled up with the skin facing surface side of the absorbent article being discarded. The non-fixed portion 64 of the band member 60 is configured to be clampable to the main body portion 20. The structure in which the non-fixed portion 64 is caught in the main body portion 20 may be an adhesive portion of the main body portion 20, or a clamping means such as an adhesive or a hook member provided on the band member 60. In addition, the fixing portion 62 of the band member 60 may be configured to be clamped to the main body portion 20. A structure in which the fixing portion 62 is caught in the main body portion 20 may be an adhesive portion of the main body portion 20, or a clamping means such as an adhesive or a hook member provided on the band member 60.

本實施形態的帶片構件60的非固定部64，是經由本體黏著部70在拋棄時卡著在本體部20。在帶片構件60藉由本體部20的黏著部卡著在本體部20的結構中，在非固定部64可沒有設置黏著劑等的卡著手段。The non-fixed portion 64 of the belt member 60 in this embodiment is stuck to the main body portion 20 through the main body adhesive portion 70 when discarded. In the structure in which the tape member 60 is stuck in the main body portion 20 by the adhesive portion of the main body portion 20, the non-fixed portion 64 may not be provided with a clamping means such as an adhesive.

如圖2所示，帶片構件60在沒有伸長的狀態(自然狀態)，也可配置在較本體部20的外緣20E更靠內側。帶片構件60若從肌膚對置面側觀看也可被本體部20遮蔽的狀態。如圖4所示，帶片構件60在伸長的狀態(伸長狀態)，也可較本體部20的外緣20E更朝外側延伸出。使用者在吸收性物品10的使用後，將本體部20朝前後方向L捲起之後，將帶片構件60延伸伸出到較本體部20的外緣20E更靠外側，而可將帶片構件60卡著在本體部20(參照圖4)。As shown in FIG. 2, the belt member 60 may be disposed more inward than the outer edge 20E of the main body portion 20 in a state (natural state) in which it is not stretched. The band member 60 can be covered by the main body portion 20 when viewed from the skin facing surface side. As shown in FIG. 4, in a stretched state (stretched state) of the band member 60, the band member 60 may extend further outward than the outer edge 20E of the main body portion 20. After using the absorbent article 10, the user rolls up the main body portion 20 in the front-rear direction L, and then extends the tape member 60 to the outside of the outer edge 20E of the main body portion 20, so that the tape member can be extended. 60 is stuck in the main body part 20 (refer FIG. 4).

根據這樣的結構，在吸收性物品10的使用中，因為帶片構件60在裏面薄片22的非肌膚對置面側被配置在較本體部20的外緣20E更靠內側，所以不會附著經血這類的體液。使用者在吸收性物品10的使用後，藉由將朝外側延伸出的帶片構件60卡著在本體黏著部70等，可維持將吸收性物品10團化後的狀態。於此，因為經血這類的體液不會附著在帶片構件60，所以，可防止帶片構件60與本體黏著部70的接合力的下降、或帶片構件的卡著手段的接合力的下降。再者，吸收性物品10的使用中，因為帶片構件60被設在裏面薄片22的非肌膚對置面側，而沒有較本體部20的外緣20E朝外側延伸，所以，帶片構件60不會直接抵接裝用者的肌膚。因此，可減低使用中的違和感、不舒適感。According to such a structure, in the use of the absorbent article 10, since the band member 60 is disposed on the non-skin facing surface side of the inner sheet 22 on the inner side than the outer edge 20E of the main body portion 20, menstrual blood does not adhere to it This type of body fluid. After the user uses the absorbent article 10, the band member 60 extending outward is caught in the main body adhesive portion 70 or the like, so that the state where the absorbent article 10 is agglomerated can be maintained. Here, since body fluid such as menstrual blood does not adhere to the band member 60, it is possible to prevent a decrease in the bonding force of the band member 60 and the main body adhesive portion 70 or a reduction in the bonding force of the band member's clamping means. . Furthermore, in the use of the absorbent article 10, since the belt member 60 is provided on the non-skin facing surface side of the inner sheet 22, and does not extend outward from the outer edge 20E of the main body portion 20, the belt member 60 Does not directly touch the skin of the wearer. Therefore, the feeling of discomfort and discomfort during use can be reduced.

又，其他的形態中，帶片構件60在沒有伸長的狀態(自然狀態)，也可較本體部20的外緣20E更朝外側延伸出。帶片構件60若從肌膚對置面側觀看也可為可視認的狀態。Moreover, in another form, the band member 60 may be extended further outside than the outer edge 20E of the main body part 20 in the state (natural state) which is not extended. The band member 60 can be viewed as viewed from the skin facing surface side.

帶片構件60被設在較本體部20的前後方向L的中心更靠後側為理想。使用者通常將吸收性物品10團化時，從吸收性物品10的前端緣E1或後端緣E2朝前後方向L開始團化。這之中，約8成的使用者，是從吸收性物品10的前端緣E1開始團化。因此，帶片構件60被設在相對於本體部20的前後方向L的中心20CL位於後側的區域為理想。帶片構件60的至少一部分可跨吸收芯23的後端緣，或被配置在較吸收芯的後端緣更靠後側。The belt member 60 is preferably provided on the rear side of the center of the main body portion 20 in the front-rear direction L. When a user usually agglomerates the absorbent article 10, the agglomeration starts from the front edge E1 or the rear edge E2 of the absorbent article 10 in the front-rear direction L. Among them, about 80% of the users are grouped from the leading edge E1 of the absorbent article 10. Therefore, it is desirable that the band member 60 is provided in a region located on the rear side with respect to the center 20CL of the main body portion 20 in the front-rear direction L. At least a part of the belt member 60 may span the rear end edge of the absorbent core 23 or be disposed on the rear side of the rear end edge of the absorbent core.

又，帶片構件60，是被設在較第1折痕F1~第3折痕F3中的最後側的第2折痕F2更靠後側更為理想。約8成的使用者，是從前側開始捲使用後的吸收性物品10。藉由將帶片構件60設在較第2折痕F2更靠後側，多數的使用者從吸收性物品10的前端緣E1開始團化，而可藉由帶片構件60卡著捲完的部分。The strip member 60 is more preferably provided on the rear side than the second crease F2 on the rearmost side of the first crease F1 to the third crease F3. About 80% of the users use the absorbent article 10 rolled from the front side. By arranging the strip member 60 on the rear side than the second crease F2, most users start to agglomerate from the front edge E1 of the absorbent article 10, and the rolled member can be caught by the strip member 60 section.

表示本實施形態的吸收性物品的具體的結構的一例。表面薄片可由基重30g/m² 的氣流不織布(PE/PET)所構成。可在表面薄片與吸收芯之間設置第二薄片。就第二薄片來說，可由與表面薄片同樣的材料所構成。在本體部的寬邊方向的外側沒有配置表面薄片，也可配置側薄片。就側薄片來說，可由基重13g/m² 的SMS不織布(PP)所構成。吸收芯的吸收材料可由針葉樹牛皮紙漿與高吸收聚合物所構成。高吸收聚合物的重量相對於吸收材料整體的重量的比率可為10%。包含***口對置域的區域的吸收芯的基重可構成較周圍的吸收芯的基重更高。包含***口對置域S1的區域的吸收芯的基重可為950g/m² ，周圍的吸收芯的基重可為300g/m² 。裏面薄片可由基重23.5g/m² 的聚乙烯薄膜(不透氣型)構成。吸收性物品也可形成有朝厚度方向壓榨表面薄片與吸收芯的壓榨部。本體黏著部可由橡膠系的熱熔型接著劑所構成。本體黏著部的基重可為27g/m² 。本體黏著部可在寬邊方向分開設置6條。各本體黏著部的寬邊方向的長度可為5mm，各本體黏著部的前後方向的長度可為320mm。吸收性物品的前後方向的長度可為420mm，吸收性物品的寬邊方向的長度可為200mm。後處理用的帶片構件可由基重35g/m² 的聚乙烯薄膜所構成。帶片構件的長邊方向的長度可為45mm，帶片構件的短邊方向的長度可為25mm。帶片構件可藉由基重100g/m² 的橡膠系的熱熔型接著劑固定在本體部。接著劑可以寬21mm，且長度5mm的範圍被塗布。在帶片構件的裏面薄片側的面可施予印刷。印刷可使用粉色系的氨基甲酸乙酯系油墨。又，就伸長的帶片構件來說，可由：基重10g/m² 的聚丙烯層、基重10g/m² 的苯乙烯系橡膠層、及基重10g/m² 的聚丙烯層的層積所構成。An example of the specific structure of the absorbent article of this embodiment is shown. The surface sheet may be composed of air-laid nonwoven fabric (PE / PET) having a basis weight of 30 g / m ² . A second sheet may be provided between the surface sheet and the absorbent core. The second sheet may be made of the same material as the surface sheet. A surface sheet is not arranged on the outer side in the widthwise direction of the main body portion, and a side sheet may be arranged. The side sheet may be composed of SMS nonwoven fabric (PP) having a basis weight of 13 g / m ² . The absorbent material of the absorbent core may be made of coniferous kraft pulp and a superabsorbent polymer. The ratio of the weight of the superabsorbent polymer to the weight of the entire absorbent material may be 10%. The basis weight of the absorbent core in the area containing the drain opening opposing domain may constitute a higher basis weight than the surrounding absorbent core. The basis weight of the absorbent core in the area including the drain opening facing region S1 may be 950 g / m ² , and the basis weight of the surrounding absorbent core may be 300 g / m ² . The inner sheet may be made of a polyethylene film (air-impermeable type) having a basis weight of 23.5 g / m ² . The absorbent article may be formed with a press section that presses the surface sheet and the absorbent core in the thickness direction. The main body adhesive portion may be composed of a rubber-based hot-melt adhesive. The basis weight of the main body adhesive portion may be 27 g / m ² . Six adhesive parts of the body can be provided in the wide side direction. The length of the wide side direction of each main body adhesive portion may be 5 mm, and the length of the front and rear direction of each main body adhesive portion may be 320 mm. The length of the absorbent article in the front-back direction may be 420 mm, and the length of the absorbent article in the width direction may be 200 mm. The strip member for post-processing may be composed of a polyethylene film having a basis weight of 35 g / m ² . The length of the strip member in the long-side direction may be 45 mm, and the length of the strip member in the short-side direction may be 25 mm. The belt member can be fixed to the main body with a rubber-based hot-melt adhesive having a basis weight of 100 g / m ² . The adhesive can be applied with a width of 21 mm and a length of 5 mm. The sheet-side surface on the back of the sheet member can be printed. Printing can use pink urethane ink. Moreover, from an elongated strip member, it may be: a basis weight of 10g / m ² polypropylene layer, a basis weight of 10g / m ² of a styrene-based rubber layer, a polypropylene layer and a basis weight of 10g / m ² layer Product.

接著，針對如此所構成的吸收性物品的彎折基點部80進行說明。彎折基點部80成為將本體部20朝前後方向L彎折時的基點。彎折基點部80藉由剛性差、厚度差、基重差等使本體部20容易彎折。Next, the bent base point portion 80 of the absorbent article thus configured will be described. The bending base point portion 80 serves as a base point when the body portion 20 is bent in the front-rear direction L. The bent base point portion 80 makes the main body portion 20 easily bendable by poor rigidity, poor thickness, poor basis weight, and the like.

彎折基點部80可包含壓榨部26。更詳細的是，壓榨部26的前端緣及後端緣構成彎折基點部80。又，在複數個壓榨部在前後方向錯開被配置的結構中，各個壓榨部的前端緣及後端緣構成彎折基點部80。構成彎折基點部80的壓榨部，是壓榨吸收芯的部分，不包含僅壓縮表面薄片的部分。壓榨部26與沒有形成壓榨部26的區域比較剛性高且厚度薄。藉由該壓榨部26構成彎折基點部80，而形成藉由厚度差及剛性差容易將本體部20緊緻地團化。適當的是如圖3所示，壓榨部26可從肌膚對置面側T1朝非肌膚對置面側T2凹陷。使用者一般來說在拋棄時，將附著***物的肌膚對置面側T1作為內側，將吸收性物品10團化。因為壓榨部26從肌膚對置面側T1朝向非肌膚對置面側T2凹陷，所以，容易使肌膚對置面側T1以接近地變形，而形成以肌膚對置面側T1為內側容易將吸收性物品團化。The bending base point portion 80 may include a press portion 26. In more detail, the front-end edge and the rear-end edge of the press part 26 constitute the bending base point part 80. Further, in a structure in which a plurality of press portions are arranged staggered in the front-rear direction, a front end edge and a rear end edge of each press portion constitute a bending base point portion 80. The pressing part constituting the bending base point part 80 is a part for pressing the absorbent core, and does not include a part for compressing only the surface sheet. The press section 26 is more rigid and thinner than the area where the press section 26 is not formed. The pressing base portion 26 constitutes the bending base point portion 80, so that the body portion 20 is easily and tightly agglomerated due to the difference in thickness and rigidity. As appropriate, as shown in FIG. 3, the pressing portion 26 may be recessed from the skin-facing surface side T1 toward the non-skin-facing surface side T2. In general, when a user discards, the skin-opposing surface side T1 to which the excrement is attached is used as the inner side, and the absorbent article 10 is agglomerated. Since the pressing portion 26 is recessed from the skin-facing surface side T1 toward the non-skin-facing surface side T2, it is easy to deform the skin-facing surface side T1 to be close, and it is easy to absorb the skin-facing surface side T1 as the inside Sex groupings.

彎折基點部80可包含基重變化部。基重變化部，是在前後方向L相對於鄰接的區域，吸收芯23的吸收材料的基重不同的部分。具體而言，吸收芯23的前端緣及後端緣構成基重變化部。高基重部的前端緣及後端緣也構成基重變化部。低基重部因前後方向的長度而不同。低基重部的前後方向的長度未滿20mm時，該低基重部的前後方向的中心構成基重變化部。低基重部的前後方向的長度為20mm以上時，該低基重部的前端緣及後端緣構成基重變化部。又，在前後方向分開設有複數個低基重部，且該複數個低基重部相連時，在前後方向分開的低基重部的各個構成基重變化部。如此所構成的基重變化部與和前後方向鄰接的區域吸收材料的基重不同，吸收芯23的厚度及剛性不同。藉由該基重變化部構成彎折基點部，根據厚度差及剛性差容易將吸收性物品緊緻地團化。The bending base point portion 80 may include a basis weight changing portion. The basis weight change portion is a portion where the basis weight of the absorbent material of the absorbent core 23 is different from the adjacent area in the front-rear direction L. Specifically, the front end edge and the rear end edge of the absorbent core 23 constitute a basis weight change portion. The leading edge and the trailing edge of the high basis weight portion also constitute a basis weight change portion. The low basis weight part varies with the length of the front-back direction. When the length of the low basis weight portion in the front-rear direction is less than 20 mm, the center of the low basis weight portion in the front-rear direction constitutes a basis weight change portion. When the length of the low basis weight portion in the front-rear direction is 20 mm or more, the front edge and the rear edge of the low basis weight portion constitute a basis weight change portion. In addition, when a plurality of low basis weight portions are provided separately in the front-rear direction, and when the plurality of low basis weight portions are connected, each of the low basis weight portions separated in the front-rear direction constitutes a basis weight change portion. The basis weight changing portion configured as described above has a different basis weight from the area of the absorbent material adjacent to the front-back direction, and the thickness and rigidity of the absorbent core 23 are different. By forming the bent base point portion by the basis weight change portion, the absorbent article can be easily and tightly grouped in accordance with the difference in thickness and rigidity.

彎折基點部80可包含被設在作為基重變化部的吸收芯23的低基重部25。低基重部25與沒有形成低基重部25的區域比較剛性高且厚度薄。藉由低基重部25構成彎折基點部80，根據厚度差及剛性差容易將吸收性物品10團化。理想的是作為基重變化部的低基重部25可沿著寬邊方向設置。在沿著圖3所示的前後方向L的剖面觀看，低基重部25的肌膚對置面的前後方向的長度L251可較低基重部25的非肌膚對置面的前後方向L的長度L252更長。因為低基重部25的肌膚對置面的前後方向的長度L251較低基重部25的非肌膚對置面的前後方向的長度L252更長，所以，容易使肌膚對置面側接近地變形，而形成以肌膚對置面側為內側容易將吸收性物品10團化。The bent base point portion 80 may include a low basis weight portion 25 provided in the absorbent core 23 as a basis weight change portion. The low basis weight portion 25 has higher rigidity and a smaller thickness than a region where the low basis weight portion 25 is not formed. By forming the bent base point portion 80 by the low basis weight portion 25, the absorbent article 10 is easily agglomerated based on the difference in thickness and rigidity. It is desirable that the low basis weight portion 25 serving as the basis weight changing portion may be provided along the broad side direction. When viewed in a cross section along the front-rear direction L shown in FIG. 3, the length L251 of the front-back direction of the skin-facing surface of the low-basis portion 25 may be shorter than the length of the front-back direction L of the non-skin-facing surface of the base-weight portion 25. L252 is longer. The length L251 of the skin-facing surface of the low-basis portion 25 is shorter than the length L252 of the non-skin-facing surface of the base-weight portion 25 is longer. Therefore, it is easy to deform the skin-facing surface side close. It is easy to agglomerate the absorbent article 10 with the skin facing surface side as the inside.

彎折基點部80可包含可為將吸收性物品10的肌膚對置面以面相對的方式折疊的折痕F1、F2及F3。在折痕在前後方向L具有一定的長度的結構中，折痕F1、F2及F3的前端緣及後端緣構成彎折基點部80。藉由折痕F1、F2及F3的折性容易使肌膚對置面側接近地變形，而形成以肌膚對置面側為內側容易將吸收性物品10團化。亦即，彎折基點部80可由壓榨部26、低基重部25及折痕的至少一個所構成。如此，藉由設置彎折基點部80，使用者容易將吸收性物品10朝前後方向捲起，而容易在團化後的狀態進行廢棄。The bending base point portion 80 may include creases F1, F2, and F3 that can be folded in a face-to-face relationship with the skin-facing surface of the absorbent article 10. In a structure in which the crease has a certain length in the front-rear direction L, the front and rear edges of the creases F1, F2, and F3 constitute a bending base point portion 80. The foldability of the creases F1, F2, and F3 easily deforms the skin facing surface side to form an absorbent article 10 that is easy to agglomerate with the skin facing surface side as the inside. That is, the bending base point portion 80 may be composed of at least one of the press portion 26, the low basis weight portion 25, and the fold. As described above, by providing the bending base point portion 80, the user can easily roll up the absorbent article 10 in the front-rear direction, and it is easy to dispose of the absorbent article 10 in a grouped state.

在第1區域R1及第2區域R2的各區域設有複數個彎折基點部80。亦即，彎折基點部80在第1區域R1設有複數個，且在第2區域R2設有複數個。因為在第1區域R1及第2區域R2的各區域設有複數個彎折基點部80，所以容易將吸收性物品整體朝前後方向團化。間隔可為和前後方向鄰接的彎折基點部彼此的前後方向的距離。此外，在彎折基點部80在前後方向分開間隔設置複數個的結構中，分別作為彎折基點部80發揮功能。可是，彎折基點部80彼此的前後方向的距離在5mm以下時，因為作為一體化的變形基點發揮功能，所以，在5mm以下的間隔被設置的複數個彎折基點部80全體構成為1個彎折基點部。A plurality of bending base point portions 80 are provided in each of the first region R1 and the second region R2. That is, a plurality of bending base point portions 80 are provided in the first region R1, and a plurality of bending base point portions 80 are provided in the second region R2. Since a plurality of bending base point portions 80 are provided in each of the first region R1 and the second region R2, the entire absorbent article is easily agglomerated in the front-rear direction. The interval may be a distance in the front-back direction between the bending base point portions adjacent to the front-back direction. In addition, in a configuration in which a plurality of bending base point portions 80 are provided at intervals in the front-rear direction, they each function as the bending base point portions 80. However, when the distance between the bending base point portions 80 in the front-back direction is 5 mm or less, the bending base point portions 80 function as an integrated deformation base point. Therefore, the plurality of bending base point portions 80 provided at intervals of 5 mm or less are configured as a whole. Bend the base point.

具體而言，本實施形態的第2區域R2的彎折基點部80，是從前側朝向後側在前後方向分開間隔以接下來的順序被設置。第2區域的彎折基點部80包含：吸收芯的前端緣、在寬邊方向上延伸的壓榨部26、在寬邊方向分開間隔的一對的點狀的壓榨部26、位在本體部的寬邊方向的中心的壓榨部26、第1折痕F1、低基重部25、低基重部25、及第3折痕F3。本實施形態的第1區域R1的彎折基點部80，是從前側朝向後側在前後方向分開間隔以接下來的順序被設置。第1區域R1的彎折基點部80包含：第3折痕F3、在前後方向L上延伸的壓榨部26、在寬邊方向上延伸的壓榨部26、第2折痕F2、在寬邊方向上延伸的壓榨部26及吸收芯的後端緣。Specifically, the bending base point portion 80 of the second region R2 of the present embodiment is provided in the following order at intervals in the front-rear direction from the front side to the rear side. The bent base point portion 80 in the second region includes a leading edge of the absorbent core, a pressing portion 26 extending in the wide side direction, a pair of dot-shaped pressing portions 26 spaced apart in the wide side direction, and a The press part 26, the 1st crease F1, the low basis weight part 25, the low basis weight part 25, and the 3rd crease F3 of the center of a width direction. The bending base point portion 80 of the first region R1 in the present embodiment is provided in the following order at intervals in the front-rear direction from the front side to the rear side. The bending base point portion 80 of the first region R1 includes a third crease F3, a press portion 26 extending in the front-rear direction L, a press portion 26 extending in the broad side direction, a second fold F2, and the wide side direction. The upper press portion 26 and the rear edge of the absorbent core.

第2區域R2的彎折基點部80的平均間隔較第1區域R1的彎折基點部80的平均間隔更短。間隔，是在各區域和前後方向L相鄰的彎折基點部80彼此的間隔。該間隔也包含吸收性物品的外端緣、與最位於前後方向的外側的彎折基點部80的距離。平均間隔，是例如在第1區域R1設有2條彎折基點部80的結構為該2條彎折基點部80的間隔D1。又，在第1區域R1設有第1彎折基點部、第2彎折基點部及第3彎折基點部的3條的結構為第1彎折基點部與第2彎折基點部的間隔、以及第2彎折基點部與第3彎折基點部的間隔的平均值。又，間隔，是第1彎折基點部與第2彎折基點部的前後方向的距離，例如，第1彎折基點部的後端緣與第2彎折基點部的前端緣的前後方向L的距離。圖1表示第1區域R1中的彎折基點部80的間隔D1、與第2區域R2的彎折基點部80的間隔D2。此外，複數個彎折基點部80全體構成1個彎折基點部時，以5mm以下的間隔而設的彎折基點部彼此的間隔不包含彎折基點部80的間隔。The average interval of the bending base point portions 80 in the second region R2 is shorter than the average interval of the bending base point portions 80 in the first region R1. The interval is an interval between the bending base point portions 80 adjacent to each other in the front-rear direction L. This interval also includes the distance between the outer end edge of the absorbent article and the bending base point portion 80 which is located most outward in the front-rear direction. The average interval is, for example, a configuration in which two bending base point portions 80 are provided in the first region R1 as the interval D1 between the two bending base point portions 80. In addition, three structures including a first bending base point portion, a second bending base point portion, and a third bending base point portion are provided in the first region R1 as a distance between the first bending base point portion and the second bending base point portion. And the average value of the distance between the second bending base point portion and the third bending base point portion. The interval is the distance in the front-back direction of the first bending base point portion and the second bending base point portion. For example, the back-and-forth direction L of the rear end edge of the first bending base point portion and the front end edge of the second bending base point portion. distance. FIG. 1 shows the interval D1 of the bending base point portion 80 in the first region R1 and the interval D2 of the bending base point portion 80 in the second region R2. In addition, when the plurality of bending base point portions 80 constitute one bending base point portion as a whole, the interval between the bending base point portions provided at intervals of 5 mm or less does not include the interval of the bending base point portions 80.

此外，在沿著寬邊方向W的同一線上設有複數個同一形狀的彎折基點部的結構中，僅選擇同一線上的彎折基點部中的1個來測量前後方向的間隔。具體而言如圖1所示，在第2區域R2設有在寬邊方向W上分開間隔的點狀的壓榨部26。點狀的壓榨部26具有設在沿著寬邊方向W的同一線FL1上的第1點狀壓榨部261及第2點狀壓榨部262。與第1點狀壓榨部261及第2點狀壓榨部262在前後方向L分開設有第3點狀壓榨部263。算出第2區域R2的彎折基點部80的平均間隔時，算入第1點狀壓榨部261與第3點狀壓榨部263的間隔D2，可不算入第2點狀壓榨部262與第3點狀壓榨部263的間隔D2。因為在前後方向L沒有與構成彎折基點，所以，第1點狀壓榨部261及第2點狀壓榨部262協動，作為將本體部20朝前後方向L彎曲的基點發揮功能。In addition, in a structure in which a plurality of bending base point portions of the same shape are provided on the same line along the broad side direction W, only one of the bending base point portions on the same line is selected to measure the interval in the front-rear direction. Specifically, as shown in FIG. 1, in the second region R2, dot-shaped press sections 26 spaced apart from each other in the widthwise direction W are provided. The dot-shaped press section 26 includes a first dot-shaped press section 261 and a second dot-shaped press section 262 provided on the same line FL1 along the widthwise direction W. A third point-shaped pressing portion 263 is provided separately from the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 in the front-back direction L. When calculating the average interval of the bending base point portion 80 in the second region R2, the interval D2 between the first point-shaped pressing portion 261 and the third point-shaped pressing portion 263 may be counted, and the second point-shaped pressing portion 262 and the third point-shaped portion may not be included. The interval D2 of the press section 263. Since the bending base point is not formed in the front-rear direction L, the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 cooperate as a base point for bending the body portion 20 in the front-back direction L.

使用者在拋棄時從第2區域R2側將吸收性物品10團化，而藉由帶片構件60將團化後的狀態的吸收性物品10作固定。此時，因為團化後的狀態下，位於內側的第2區域R2的彎折基點部80的平均間隔短，所以可緊緻地作團化。又，因為團化的狀態下，在位於外側的第1區域R1也設有複數個彎折基點部80，所以，第1區域R1及第2區域R2皆可容易地團化，且容易維持團化後的狀態。因此，將吸收性物品10維持於緊緻的團化後的狀態，而可帶片構件60清潔地進行廢棄。When the user discards the absorbent article 10 from the second region R2 side, the absorbent article 10 is agglomerated by the belt member 60, and the absorbent article 10 in a state of being agglomerated is fixed. At this time, since the average interval between the bending base point portions 80 of the second region R2 located on the inner side is short in the state after being agglomerated, the agglomeration can be performed tightly. In addition, since the plurality of bending base point portions 80 are also provided in the first region R1 located outside in the state of clustering, both the first region R1 and the second region R2 can be easily clustered, and the cluster can be easily maintained. After the state. Therefore, the absorbent article 10 is maintained in a tight and compacted state, and the sheet member 60 can be discarded cleanly.

第2區域R2的彎折基點部80的數量可較第1區域R1的彎折基點部80的數量更多。因為團化後的狀態下，位於內側的第2區域R2的彎折基點部的數量多，所以，在團化後的狀態的內側形成有許多個變形基點，而更容易緊緻地團化。彎折基點部80的數量，是藉由加上全部的彎折基點部80的數量所算出。例如，在沿著寬邊方向W的同一線上設有複數個同一形狀的彎折基點部的結構中，不只選擇同一線上的彎折基點部中的1個，而是加上全部的彎折基點部來算出彎折基點部的數量。將吸收性物品團化時，即使欲朝前後方向捲起，也會有相對於前後方向斜斜地被捲起的情況。這樣的情況，因為第1點狀壓榨部261與第2點狀壓榨部262作為不同的彎折基點發揮功能。The number of bending base point portions 80 in the second region R2 may be larger than the number of bending base point portions 80 in the first region R1. Since the number of bent base point portions of the second region R2 located on the inner side is large in the state after the massing, a large number of deformed base points are formed on the inner side of the state after the massing, which makes it easier to compact the body. The number of the bending base point portions 80 is calculated by adding the total number of the bending base point portions 80. For example, in a structure in which a plurality of bending base point portions of the same shape are provided on the same line along the widthwise direction W, not only one of the bending base point portions on the same line is selected, but all the bending base points are added. To calculate the number of bending base points. When the absorbent article is agglomerated, even if it is intended to be rolled up in the front-rear direction, it may be rolled up obliquely with respect to the front-back direction. In this case, the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 function as different bending base points.

彎折基點部80可沿著寬邊方向W延伸。沿著寬邊方向W延伸的結構不只有與寬邊方向W平行的結構，也包含相對於寬邊方向W以未滿45度傾斜的結構。將吸收性物品10團化時的變形基點沿著寬邊方向W延伸，而容易將吸收性物品10的寬邊方向全域朝前後方向團化。The bent base point portion 80 may extend along the broad side direction W. The structure extending along the wide-side direction W is not only a structure parallel to the wide-side direction W, but also includes a structure inclined at less than 45 degrees with respect to the wide-side direction W. The deformation base point when the absorbent article 10 is agglomerated extends along the broad side direction W, and it is easy to agglomerate the entire wide side direction of the absorbent article 10 in the front-rear direction.

彎折基點部的形狀沒有被限定，也可為點狀，也可為帶狀，也可為圓弧狀，也可為多角形狀。彎折基點部80可具有：第1彎折基點部81、與第2彎折基點部82。第1彎折基點部81的寬邊方向W的長度W81較第1彎折基點部81的前後方向L的長度L81更長。第2彎折基點部82的前後方向L的長度L82較第2彎折基點部82的寬邊方向W的長度W82更長。本體部20以第1彎折基點部81為基點容易朝前後方向L彎曲，以第2彎折基點部82為基點在寬邊方向W也容易彎曲。吸收性物品整體中的第1彎折基點部81的數量可較第2彎折基點部82的數量更多。將吸收性物品團化時，相較於寬邊方向更容易朝前後方向團化。因此，容易將吸收性物品朝前後方向更緊緻地團化，而更容易維持團化後的狀態。適合的是，在第2區域R2，第1彎折基點部81的數量可較第2彎折基點部82的數量更多，在第1區域R1，第1彎折基點部81的數量可較第2彎折基點部82的數量更多。The shape of the bending base point portion is not limited, and may be a dot shape, a band shape, an arc shape, or a polygonal shape. The bending base point portion 80 may include a first bending base point portion 81 and a second bending base point portion 82. The length W81 of the widthwise direction W of the first bending base point portion 81 is longer than the length L81 of the first bending base point portion 81 in the front-rear direction L. The length L82 of the front-back direction L of the second bending base point portion 82 is longer than the length W82 of the widthwise direction W of the second bending base point portion 82. The main body portion 20 is easily bent in the front-rear direction L using the first bending base point portion 81 as a base point, and is also easily bent in the wide side direction W using the second bending base point portion 82 as a base point. The number of the first bending base point portions 81 in the entire absorbent article may be larger than the number of the second bending base point portions 82. When the absorbent article is agglomerated, it is easier to agglomerate in the front-back direction than in the broad side direction. Therefore, it is easy to agglomerate the absorbent article more tightly in the front-rear direction, and it is easier to maintain the agglomerated state. It is suitable that in the second region R2, the number of the first bending base point portions 81 may be greater than the number of the second bending base point portions 82, and in the first region R1, the number of the first bending base point portions 81 may be larger. The number of the second bending base point portions 82 is larger.

又，吸收性物品10可為容易維持朝前後方向L團化後的狀態的結構。如圖2所示，第1區域R1的寬邊方向W的最大長度WR1可較第2區域R2的寬邊方向的最大長度WR2更長。因為團化後的狀態下，位於外側的第1區域的寬邊方向的最大長度WR1長，所以，可藉由位於外側的第1區域R1覆蓋團化後的狀態下位於內側的第2區域R2，而成為更容易維持團化後的狀態。In addition, the absorbent article 10 may have a structure in which it is easy to maintain a state in which it is agglomerated in the front-rear direction L. As shown in FIG. 2, the maximum length WR1 of the widthwise direction W of the first region R1 may be longer than the maximum length WR2 of the widthwise direction of the second region R2. Since the maximum length WR1 in the wide-side direction of the first region located on the outer side is long in the grouped state, the second region R2 located on the inner side in the grouped state can be covered by the first region R1 located on the outer side. , And it becomes easier to maintain the state after grouping.

彎折基點部80在從第1區域R1中的本體部20的前後方向的外端緣到本體部20的前後方向的長度的1/3的範圍設置3個以上。第1區域R1中的本體部20的前後方向的外端緣為本實施形態中的本體部20的後端緣。圖1表示從本體部20的前後方向的外端緣到本體部20的前後方向的長度的1/3的範圍R3。將本體部朝前後方向團化後的狀態的周長，一般來說是形成相對於本體部的前後方向的長度為1/3左右。相對於本體部的前後方向的長度的1/3，是成為在團化後的狀態下位於外側的表面的部分。藉由在該部分設置3個以上的彎折基點部，而更容易維持團化後的狀態。Three or more bending base point portions 80 are provided in a range from the outer end edge of the main body portion 20 in the front-rear direction in the first region R1 to 1/3 of the length of the main body portion 20 in the front-rear direction. An outer end edge of the main body portion 20 in the front-rear direction in the first region R1 is a rear end edge of the main body portion 20 in this embodiment. FIG. 1 shows a range R3 from the outer edge of the main body portion 20 in the front-rear direction to the length of the main body portion 20 in the front-rear direction. In general, the perimeter of the state in which the main body portion is clustered in the front-rear direction is formed so that the length relative to the front-rear direction of the main body portion is about 1/3. One third of the length in the front-rear direction with respect to the main body portion is a portion that becomes the outer surface in a state after being agglomerated. By providing three or more bent base point portions in this portion, it is easier to maintain the state after the grouping.

接著，針對其他的實施形態的吸收性物品進行說明。此外，在以下的變形例及第2形態的說明中，關於與上述的實施形態同樣之處，是使用同符號並省略說明。圖5，是從變形例1的吸收性物品10A的非肌膚對置面側觀看的俯視圖。變形例1的吸收性物品具有高基重部27。變形例1的吸收性物品10A，是在中心20CL與吸收性物品的後端緣之間設有帶片構件60。因此，第1區域R1較第2區域R2更位於後側。在變形例1的吸收性物品10A設有複數個彎折基點部80。Next, an absorbent article according to another embodiment will be described.

第1區域R1的彎折基點部80的平均間隔較第2區域R2的彎折基點部80的平均間隔更短。間隔，是在各區域和前後方向L相鄰的彎折基點部80彼此的間隔。該間隔也包含吸收性物品的外端緣、與最位於前後方向的外側的彎折基點部80的距離。平均間隔，是例如在第1區域R1設有2個彎折基點部80的結構為該2個彎折基點部80的間隔D1。又，在第1區域R1設有第1彎折基點部、第2彎折基點部及第3彎折基點部的3個的結構為第1彎折基點部與第2彎折基點部的間隔、以及第2彎折基點部與第3彎折基點部的間隔的平均值。又，間隔，是第1彎折基點部與第2彎折基點部的前後方向的距離，例如，第1彎折基點部的後端緣與第2彎折基點部的前端緣的前後方向L的距離。圖6表示第1區域R1中的彎折基點部80的間隔D1、與第2區域R2的彎折基點部80的間隔D2。此外，複數個彎折基點部80全體構成1個彎折基點部時，以5mm以下的間隔而設的彎折基點部彼此的間隔不包含彎折基點部80的間隔。The average interval of the bending base point portions 80 in the first region R1 is shorter than the average interval of the bending base point portions 80 in the second region R2. The interval is an interval between the bending base point portions 80 adjacent to each other in the front-rear direction L. This interval also includes the distance between the outer end edge of the absorbent article and the bending base point portion 80 which is located most outward in the front-rear direction. The average interval is, for example, a configuration in which two bending base point portions 80 are provided in the first region R1 as the interval D1 between the two bending base point portions 80. In addition, three structures including a first bending base point portion, a second bending base point portion, and a third bending base point portion are provided in the first region R1 as an interval between the first bending base point portion and the second bending base point portion. And the average value of the distance between the second bending base point portion and the third bending base point portion. The interval is the distance in the front-back direction of the first bending base point portion and the second bending base point portion. For example, the back-and-forth direction L of the rear end edge of the first bending base point portion and the front end edge of the second bending base point portion. distance. FIG. 6 shows the interval D1 of the bending base point portion 80 in the first region R1 and the interval D2 of the bending base point portion 80 in the second region R2. In addition, when the plurality of bending base point portions 80 constitute one bending base point portion as a whole, the interval between the bending base point portions provided at intervals of 5 mm or less does not include the interval of the bending base point portions 80.

此外，在沿著寬邊方向W的同一線上設有複數個同一形狀的彎折基點部的結構中，僅選擇同一線上的彎折基點部中的1個來測量間隔。具體而言如圖6所示，在第2區域R2設有在寬邊方向W上分開間隔的點狀的壓榨部26。點狀的壓榨部26具有設在沿著寬邊方向W的同一線FL1上的第1點狀壓榨部261及第2點狀壓榨部262。與第1點狀壓榨部261及第2點狀壓榨部262在前後方向L分開設有第3點狀壓榨部263。算出第2區域R2的彎折基點部80的平均間隔時，可算入第1點狀壓榨部261與第3點狀壓榨部263的間隔D1，不算入第2點狀壓榨部262與第3點狀壓榨部263的間隔D1。因為在前後方向L沒有與構成彎折基點，所以，第1點狀壓榨部261及第2點狀壓榨部262協動，作為將本體部20朝前後方向L彎曲的基點發揮功能。In addition, in a structure in which a plurality of bending base point portions of the same shape are provided on the same line along the broad side direction W, only one of the bending base point portions on the same line is selected to measure the interval. Specifically, as shown in FIG. 6, in the second region R2, dot-shaped press sections 26 spaced apart from each other in the widthwise direction W are provided. The dot-shaped press section 26 includes a first dot-shaped press section 261 and a second dot-shaped press section 262 provided on the same line FL1 along the widthwise direction W. A third point-shaped pressing portion 263 is provided separately from the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 in the front-back direction L. When calculating the average interval of the bending base point portion 80 in the second region R2, the interval D1 between the first point-shaped pressing portion 261 and the third point-shaped pressing portion 263 can be calculated, and the second point-shaped pressing portion 262 and the third point are not counted The interval D1 of the shape press section 263. Since the bending base point is not formed in the front-rear direction L, the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 cooperate as a base point for bending the body portion 20 in the front-back direction L.

使用者在拋棄時從第2區域側將吸收性物品團化，而藉由帶片構件將團化後的狀態的吸收性物品作固定。此時，團化後位於外側的第1區域R1在團化後的狀態下沿著位於內側的部分(第2區域R2)被捲起。因為第1區域R1的彎折基點部80的平均間隔短，所以可將團化後的狀態下位於外側的第1區域R1用短的間隔彎折。因此，將第2區域R2團化後的狀態下，即使朝外面形成凹凸，也容易將第1區域R1團化成圓形狀。又，因為團化的狀態下，在位於內側的第2區域R2也設有複數個彎折基點部80，所以，第1區域R1及第2區域R2皆可容易藉由彎折基點部80團化，且容易維持團化後的狀態。因此，將吸收性物品維持在團化後的狀態，而可藉由後處理用的帶片構件清潔地進行廢棄。When the user discards the absorbent article from the second area side, the absorbent article in a state of being agglomerated is fixed by the belt member. At this time, the first region R1 located on the outer side after being agglomerated is rolled up along the inner portion (the second region R2) in a state after being agglomerated. Since the average interval of the bending base point portions 80 in the first region R1 is short, the first region R1 that is located outside in the state of being lumped can be bent at a short interval. Therefore, in a state where the second region R2 is agglomerated, it is easy to agglomerate the first region R1 into a circular shape even if unevenness is formed outward. In addition, since the plurality of bending base point portions 80 are also provided in the second region R2 located on the inner side in the state of clustering, the first region R1 and the second region R2 can be easily bent by bending the base point portion 80. And easy to maintain the state after the group. Therefore, the absorbent article is maintained in a state after being agglomerated, and can be discarded cleanly by the belt member for post-processing.

第1區域R1的彎折基點部80的數量可較第2區域R2的彎折基點部80的數量更多。因為團化後的狀態下，在位於外側的第2區域R2的彎折基點部的數量多，所以，在團化後的狀態的外側形成有許多個變形基點，而更容易維持緊緻的團化狀態。彎折基點部80的數量，是藉由加上全部的彎折基點部80的數量所算出。例如，在沿著寬邊方向W的同一線上設有複數個同一形狀的彎折基點部的結構中，不只選擇同一線上的彎折基點部中的1個，而是加上全部的彎折基點部來算出彎折基點部的數量。將吸收性物品團化時，即使欲朝前後方向捲起，也會有相對於前後方向斜斜地被捲起的情況。這樣的情況，因為第1點狀壓榨部261與第2點狀壓榨部262作為不同的彎折基點發揮功能。The number of bending base point portions 80 in the first region R1 may be larger than the number of bending base point portions 80 in the second region R2. Since the number of bending base points in the second region R2 on the outer side is large in the state after the mass, many deformation base points are formed on the outer side of the state after the mass, and it is easier to maintain a tight mass.化 State. The number of the bending base point portions 80 is calculated by adding the total number of the bending base point portions 80. For example, in a structure in which a plurality of bending base point portions of the same shape are provided on the same line along the widthwise direction W, not only one of the bending base point portions on the same line is selected, but all the bending base points are added. To calculate the number of bending base points. When the absorbent article is agglomerated, even if it is intended to be rolled up in the front-rear direction, it may be rolled up obliquely with respect to the front-back direction. In this case, the first point-shaped pressing portion 261 and the second point-shaped pressing portion 262 function as different bending base points.

接著，針對變形例2的吸收性物品進行說明。圖8，是從變形例2的吸收性物品10C的非肌膚對置面側觀看的俯視圖。變形例2的吸收性物品10C具有高基重部27。變形例2的吸收性物品10C，是在中心20CL與吸收性物品的前端緣之間設有帶片構件60。因此，第1區域R1較第2區域R2更位於前側。在變形例2的吸收性物品10C設有複數個彎折基點部80。Next, an absorbent article according to Modification 2 will be described.
