關於側片3，如圖4所示，構成側片3之上述2片片材31、32中位於側片3之外表面側(圖4中為Q側)之片材32於側片3之兩端部3a、3b向該片材32之內表面側(圖4中為Q側)回折，該回折之部分分別經由補強用接著劑層63、64而接合於該片材32之內表面。 As for the side sheet 3, as shown in FIG. 4, among the above-mentioned two sheets 31 and 32 constituting the side sheet 3, the sheet 32 located on the outer surface side of the side sheet 3 (the Q side in FIG. Both ends 3a, 3b are folded back toward the inner surface side (Q side in FIG. 4) of the sheet 32, and the folded portions are joined to the inner surface of the sheet 32 through the adhesive layers 63, 64 for reinforcement, respectively.

另一方面，構成側片3之上述2片片材31、32中位於側片3之內表面側(圖4中為P側)之片材31既未向該片材31之外表面側回折，亦未向內表面側回折。 On the other hand, among the above-mentioned two sheets 31 and 32 constituting the side sheet 3 , the sheet 31 located on the inner surface side (the P side in FIG. 4 ) of the side sheet 3 is not folded back toward the outer surface side of the sheet 31 . , and did not fold back to the inner surface side.

如此，構成側片3之上述2片片材31、32既可向該片材31、32之外表 面側(圖4中為Q側)或內表面側(圖4中為P側)回折，亦可不向該片材31、32之外表面側或內表面側回折。 In this way, the above-mentioned two sheets 31 and 32 constituting the side panel 3 may face the outer surfaces of the sheets 31 and 32. The surface side (Q side in FIG. 4 ) or the inner surface side (P side in FIG. 4 ) is folded back, and the sheets 31 and 32 may not be folded back toward the outer surface side or the inner surface side.

如圖4所示，本實施形態之側片3於外表面側之片材32之寬度方向上之兩端部3a、3b各者形成有補強用接著劑層63、64。如圖4所示，構成側片3之2片片材31、32之寬度方向之兩端部3a、3b所形成之補強用接著劑層63、64既可形成於位於側片3之外表面側(圖4中為Q側)之片材32之向內表面側回折之部分，亦可形成於位於側片3之外表面側(圖4中為Q側)之片材32之向外表面側回折之部分。於任一情形時，均藉由形成補強用接著劑層，而提高側片3之接合強度。如圖4所示，補強用接著劑層63、64既可分別與將該2片片材31、32間接合之接著劑層35、36連續，亦可不與其等連續。 As shown in FIG. 4 , in the side sheet 3 of the present embodiment, both ends 3 a and 3 b in the width direction of the sheet 32 on the outer surface side are each formed with adhesive layers 63 and 64 for reinforcement. As shown in FIG. 4 , the reinforcing adhesive layers 63 and 64 formed at both ends 3 a and 3 b in the width direction of the two sheets 31 and 32 constituting the side sheet 3 may be formed on the outer surface of the side sheet 3 . The portion folded back toward the inner surface side of the sheet 32 on the side (Q side in FIG. 4 ) may also be formed on the outer surface of the sheet 32 located on the outer surface side (Q side in FIG. 4 ) of the side panel 3 The part that turns back sideways. In any case, the bonding strength of the side sheet 3 is improved by forming the adhesive layer for reinforcement. As shown in FIG. 4, the adhesive agent layers 63 and 64 for reinforcement may be continuous with the adhesive agent layers 35 and 36 which join the two sheets 31 and 32, respectively, and may not be continuous with them.

再者，構成側片3之2片片材31、32亦可均於寬度方向之兩端部3a、3b不具有回折部分。 Furthermore, the two sheets 31 and 32 constituting the side panel 3 may not have folded-back portions at both ends 3a and 3b in the width direction.

側片3經由連接用接著劑層62而接合於外層複合片材22及配置於側片3之內表面側之肌膚側片材20。連接用接著劑層62於X方向上，在較側片3之內方側緣3c更靠外方側，將側片3與外層複合片材22接合，且在較側片3之內方側緣3c更靠內方側，將外層複合片材22與肌膚側片材20接合。更具體而言，如圖5所示，連接用接著劑層62配置於側片3之內方側緣3c之外方側及內方側，於該外方側將側片3之內方端部3b與防漏片材22a之間接合，並且於該內方側將防漏片材22a與立體防護形成用片材24或表面片材21之間接合。 The side sheet 3 is joined to the outer-layer composite sheet 22 and the skin-side sheet 20 arranged on the inner surface side of the side sheet 3 via the adhesive layer 62 for connection. The adhesive layer 62 for connection is located on the outer side of the side sheet 3 on the outer side in the X direction, and joins the side sheet 3 and the outer layer composite sheet 22, and is on the inner side of the side sheet 3. The edge 3c is further inward, and the outer layer composite sheet 22 and the skin-side sheet 20 are joined together. More specifically, as shown in FIG. 5, the adhesive layer 62 for connection is arranged on the outer side and the inner side of the inner side edge 3c of the side sheet 3, and the inner end of the side sheet 3 is placed on the outer side. The part 3b is joined to the leak-proof sheet 22a, and the leak-proof sheet 22a is joined to the three-dimensional shield forming sheet 24 or the surface sheet 21 on the inner side.

於本實施形態中，如圖4所示，連接用接著劑層62與將側片3之內表面側之片材31與立體防護形成用片材24接合的接著劑層66隔開，但亦可 與該接著劑層66連續。又，如圖4所示，連接用接著劑層62與將表面片材21與立體防護形成用片材24接合的接著劑層67隔開，但亦可與該接著劑層67連續。 In this embodiment, as shown in FIG. 4, the adhesive layer 62 for connection is separated from the adhesive layer 66 for joining the sheet 31 on the inner surface side of the side sheet 3 and the sheet 24 for forming a three-dimensional shield, but it is also Can It is continuous with the adhesive layer 66 . Moreover, as shown in FIG. 4, although the adhesive agent layer 62 for connection is spaced apart from the adhesive agent layer 67 which joins the surface sheet 21 and the sheet|seat 24 for three-dimensional shield formation, it may be continuous with this adhesive agent layer 67.

如圖5所示，外層接著劑層61將構成外層複合片材22之防漏片材22a與外層不織布22b接合，進而，於尿布1之厚度方向Z上與側片3之內方側緣3c重疊之位置具有未配置接著劑之間斷部7。 As shown in FIG. 5, the outer layer adhesive layer 61 joins the leak-proof sheet 22a constituting the outer layer composite sheet 22 and the outer layer non-woven fabric 22b, and further, in the thickness direction Z of the diaper 1 and the inner side edge 3c of the side sheet 3 The overlapping position has the adhesive gap 7 not arranged.

於間斷部7中，防漏片材22a未與外層不織布22b接合，藉此，防漏片材22a變得易於在寬度方向(X方向)上伸長。藉此，於將側片3向外方側拉伸而穿著尿布1時，可抑制應變局部地集中於防漏片材22a，從而防漏片材22a難以在寬度方向上裂開。 In the discontinuous portion 7, the leakage preventing sheet 22a is not joined to the outer layer nonwoven fabric 22b, whereby the leakage preventing sheet 22a becomes easily elongated in the width direction (X direction). Thereby, when the side sheet 3 is stretched outward and the diaper 1 is worn, strain can be suppressed from being locally concentrated on the leak-proof sheet 22a, and the leak-proof sheet 22a is less likely to be split in the width direction.

另一方面，若防漏片材22a之外表面經由外層接著劑層61而與外層不織布22b於寬度方向上連續地接合，又，防漏片材22a之內表面經由連接用接著劑層62而與側片3及表面片材21於寬度方向上連續地接合，則防漏片材22a向寬度方向(X方向)之內方及外方之任一者均難以伸長。因此，若將側片3向外方側拉伸，則會經由連接用接著劑層62對防漏片材22a向外方側施加張力，從而應變會局部地集中於側片3之內方側緣3c附近。由此，於尿布之厚度方向Z之與上述內方側緣3c重疊之部分，存在防漏片材22a裂開之情況。 On the other hand, if the outer surface of the leakage preventing sheet 22a is continuously bonded to the outer nonwoven fabric 22b in the width direction through the outer adhesive layer 61, and the inner surface of the leakage preventing sheet 22a is bonded through the bonding adhesive layer 62 When continuously joined to the side sheet 3 and the surface sheet 21 in the width direction, the leakage preventing sheet 22a is difficult to extend either inward or outward in the width direction (X direction). Therefore, when the side sheet 3 is pulled outward, tension is applied to the leakage preventing sheet 22a outward through the bonding adhesive layer 62, and strain is locally concentrated on the inner side of the side sheet 3 near edge 3c. Thereby, in the part which overlaps with the said inner side edge 3c in the thickness direction Z of a diaper, the leak prevention sheet|seat 22a may crack.

間斷部7配置於厚度方向Z上與側片3之內方側緣3c重疊之位置。使用內方側緣線3cL(參照圖5)表示該與內方側緣3c重疊之位置。 The discontinuous part 7 is arrange|positioned in the position which overlaps with the inner side edge 3c of the side panel 3 in the thickness direction Z. As shown in FIG. The position overlapping the inner side edge 3c is indicated by the inner side edge line 3cL (refer to FIG. 5).

就進一步抑制防漏片材22a於寬度方向上裂開之情況之觀點而言，寬度方向(X方向)上之間斷部7之長度W1(參照圖5)較佳為1mm以上，更佳為1.5mm以上，又，較佳為5mm以下，更佳為3mm以下，較佳為1mm 以上且5mm以下，更佳為1.5mm以上且3mm以下。 The length W1 (refer to FIG. 5 ) of the interrupted portion 7 in the width direction (X direction) is preferably 1 mm or more, more preferably 1.5 mm, from the viewpoint of further suppressing cracking of the leakage preventing sheet 22 a in the width direction. mm or more, and preferably 5 mm or less, more preferably 3 mm or less, more preferably 1 mm It is more than 5 mm and less than 5 mm, More preferably, it is more than 1.5 mm and less than 3 mm.

又，於將間斷部7以側片3之內方側緣線3cL為界分為內方側部分7a及外方側部分7b時，寬度方向(X方向)上之內方側部分7a之長度W1a(參照圖5)較佳為0.5mm以上，更佳為1mm以上，又，較佳為5mm以下，更佳為3mm以下，較佳為0.5mm以上且5mm以下，更佳為1mm以上且3mm以下。進而，寬度方向(X方向)上之外方側部分7b之長度W1b(參照圖5)較佳為0.5mm以上，更佳為1mm以上，又，較佳為5mm以下，更佳為3mm以下，較佳為0.5mm以上且5mm以下，更佳為1mm以上且3mm以下。 Moreover, when the discontinuous portion 7 is divided into the inner side portion 7a and the outer side portion 7b with the inner side edge line 3cL of the side panel 3 as the boundary, the length of the inner side portion 7a in the width direction (X direction) W1a (see FIG. 5 ) is preferably 0.5 mm or more, more preferably 1 mm or more, and is preferably 5 mm or less, more preferably 3 mm or less, preferably 0.5 mm or more and 5 mm or less, more preferably 1 mm or more and 3 mm the following. Furthermore, the length W1b (refer to FIG. 5 ) of the outer side portion 7b in the width direction (X direction) is preferably 0.5 mm or more, more preferably 1 mm or more, more preferably 5 mm or less, more preferably 3 mm or less, It is preferably 0.5 mm or more and 5 mm or less, and more preferably 1 mm or more and 3 mm or less.

再者，於本說明書中，間斷部7等各部之尺寸等係於使彈性構件33等彈性構件伸長而將側片或尿布擴展至成為設計尺寸(與於完全排除彈性構件之影響之狀態下呈平面狀擴展時之尺寸相同)為止之狀態下進行測定。 Furthermore, in this specification, the size of each part such as the discontinuous portion 7 is determined by extending the elastic member such as the elastic member 33 to expand the side panel or the diaper to the design size (the same as the state in which the influence of the elastic member is completely excluded). Measured in a state where the dimensions are the same when expanded in a flat shape).

如圖5所示，外層接著劑層61於尿布1之厚度方向Z上與側片3之包含內方側緣3c在內之其附近重疊之區域R中，具有配置有接著劑之部分71於寬度方向(X方向)上間斷地配置而成之條紋塗佈部70。於該配置有接著劑之部分71間，配置有未配置接著劑之部分72，該部分72中之一個構成上述間斷部7。根據該構成，可進一步抑制於將側片3向寬度方向之外方拉伸時對防漏片材22a之應變局部地集中於上述內方側緣3c附近之區域。如此，外層接著劑層61較佳為於尿布1之厚度方向Z上與側片3之內方側緣3c及其附近重疊之區域R中，具有條紋塗佈部70。又，於條紋塗佈部70，較佳為位於配置有接著劑之部分71間之未配置接著劑之部分72中之一個構成間斷部7。條紋塗佈部70只要包含間斷部7之未配置接著劑之部分72為2個以上即可。 As shown in FIG. 5 , the outer adhesive layer 61 has a portion 71 in which the adhesive is disposed in the region R overlapping the vicinity of the side sheet 3 including the inner side edge 3c in the thickness direction Z of the diaper 1 . The stripe coating portion 70 is arranged intermittently in the width direction (X direction). Between the portions 71 where the adhesive is arranged, a portion 72 where the adhesive is not arranged is arranged, and one of the portions 72 constitutes the above-mentioned discontinuous portion 7 . According to this structure, when the side sheet 3 is stretched outward in the width direction, the strain on the leakage preventing sheet 22a can be suppressed from being locally concentrated in the region near the inner side edge 3c. In this way, the outer adhesive layer 61 preferably has a striped coating portion 70 in the region R overlapping the inner side edge 3c of the side sheet 3 and its vicinity in the thickness direction Z of the diaper 1 . In addition, in the stripe coating portion 70 , it is preferable that one of the portions 72 where the adhesive is not arranged between the portions 71 where the adhesive is arranged constitutes the discontinuous portion 7 . The stripe coating portion 70 may include two or more portions 72 of the discontinuous portion 7 where the adhesive is not disposed.

條紋塗佈部70只要配置於外層接著劑層61之於厚度方向Z上與側片3 之內方側緣3c及其附近重疊之區域R即可，亦可遍及外層接著劑層61之寬度方向全域而配置。與側片3之內方側緣3c及其附近重疊之區域R係於寬度方向(X方向)上距上述內方側緣3c之兩側分別為10mm以內之區域。 The stripe coating portion 70 only needs to be arranged between the outer adhesive layer 61 and the side sheet 3 in the thickness direction Z. The inner side edge 3c and the region R overlapping the vicinity thereof may be sufficient, and may be arranged over the entire width direction of the outer adhesive layer 61 . The area|region R which overlaps with the inner side edge 3c of the side panel 3 and its vicinity is an area|region respectively within 10 mm from both sides of the said inner side edge 3c in the width direction (X direction).

就更確實地發揮上述效果之觀點而言，寬度方向(X方向)上之配置有接著劑之部分71之長度W2(參照圖5)較佳為0.5mm以上，更佳為1mm以上，又，較佳為3mm以下，更佳為2mm以下，較佳為0.5mm以上且3mm以下，更佳為1mm以上且2mm以下。 From the viewpoint of exhibiting the above-mentioned effects more reliably, the length W2 (refer to FIG. 5 ) of the portion 71 in the width direction (X direction) where the adhesive is arranged is preferably 0.5 mm or more, more preferably 1 mm or more, and It is preferably 3 mm or less, more preferably 2 mm or less, preferably 0.5 mm or more and 3 mm or less, and more preferably 1 mm or more and 2 mm or less.

又，寬度方向(X方向)上之配置有接著劑之部分71之長度W2(參照圖5)相對於未配置接著劑之部分72之長度W3(參照圖5)，較佳為20%以上，更佳為30%以上，又，較佳為100%以下，更佳為80%以下，較佳為20%以上且100%以下，更佳為30%以上且80%以下。 Further, the length W2 (refer to FIG. 5 ) of the portion 71 where the adhesive is arranged in the width direction (X direction) is preferably 20% or more of the length W3 (refer to FIG. 5 ) of the portion 72 where the adhesive is not arranged, More preferably 30% or more, and more preferably 100% or less, more preferably 80% or less, more preferably 20% or more and 100% or less, more preferably 30% or more and 80% or less.

又，寬度方向(X方向)上之未配置接著劑之部分72之長度W3(參照圖5)較佳為1mm以上，更佳為1.5mm以上，又，較佳為5mm以下，更佳為3mm以下，較佳為1mm以上且5mm以下，更佳為1.5mm以上且3mm以下。 Further, the length W3 (see FIG. 5 ) of the portion 72 in the width direction (X direction) where the adhesive is not disposed is preferably 1 mm or more, more preferably 1.5 mm or more, more preferably 5 mm or less, more preferably 3 mm Hereinafter, it is preferably 1 mm or more and 5 mm or less, and more preferably 1.5 mm or more and 3 mm or less.

於較側片3之內方側緣3c更靠外方側，外層複合片材22較佳為防漏片材22a與外層不織布22b之間之寬度方向之剪切強度大於寬度方向上之防漏片材22a之拉伸強度。根據該構成，對於將側片3向寬度方向之外方拉伸時施加至外層接著劑層61之剪切方向之負載，可更確實地擔保側片3與吸收性本體2之接合強度。該外層複合片材22之剪切強度是否大於防漏片材22a之拉伸強度可藉由將側片3拉伸時相較於防漏片材22a與外層不織布22b之剝離，防漏片材22a先於寬度方向(X方向)上裂開而判斷。更詳細地確認該外層複合片材22之剪切強度與防漏片材22a之拉伸強度之大小關係 的方法如下所示。將圖5所示之包含側片3之內方側緣3c附近之部分的部分作為將長邊設為寬度方向(X方向)且將短邊設為長度方向(Y方向)之長方形狀之樣本片而自尿布1切出。將該樣本片之防漏片材22a及外層不織布22b在相當於內方側緣線3cL之位置沿長度方向(Y方向)裁剪。其後，夾持該樣本片之側片3及吸收性本體2之較內方側緣線3cL更靠長度方向中央線CL側，沿寬度方向(X方向)之朝向拉伸直至樣本片破斷為止。此時，若相較於防漏片材22a與外層不織布22b之剝離，防漏片材22a先於寬度方向(X方向)上裂開，則可判斷為外層複合片材22之剪切強度大於防漏片材22a之拉伸強度。 On the outer side than the inner side edge 3c of the side sheet 3, the outer layer composite sheet 22 preferably has a shear strength in the width direction between the leak-proof sheet 22a and the outer layer non-woven fabric 22b greater than the leakage resistance in the width direction. Tensile strength of sheet 22a. According to this configuration, the bonding strength between the side sheet 3 and the absorbent body 2 can be more reliably secured against the load applied to the shear direction of the outer adhesive layer 61 when the side sheet 3 is stretched outward in the width direction. Whether the shear strength of the outer layer composite sheet 22 is greater than the tensile strength of the leak-proof sheet 22a can be determined by comparing the peeling of the leak-proof sheet 22a and the outer non-woven fabric 22b when the side sheet 3 is stretched. 22a is judged prior to cracking in the width direction (X direction). The relationship between the shear strength of the outer layer composite sheet 22 and the tensile strength of the leak-proof sheet 22a is confirmed in more detail The method is shown below. The portion including the portion near the inner side edge 3c of the side panel 3 shown in FIG. 5 is used as a sample of a rectangular shape in which the long side is the width direction (X direction) and the short side is the longitudinal direction (Y direction). The pieces are cut out from the diaper 1. The leak-proof sheet 22a and the outer nonwoven fabric 22b of the sample sheet were cut along the longitudinal direction (Y direction) at a position corresponding to the inner side edge line 3cL. Then, the side sheet 3 and the absorbent body 2 sandwiching the sample sheet are closer to the longitudinal center line CL than the inner side edge line 3cL, and stretched in the direction of the width direction (X direction) until the sample sheet is broken. until. At this time, if the leak-proof sheet 22a is cracked earlier in the width direction (X direction) than the peeling of the leak-proof sheet 22a and the outer non-woven fabric 22b, it can be determined that the shear strength of the outer-layer composite sheet 22 is greater than Tensile strength of the leak-proof sheet 22a.

外層複合片材22之剪切強度可藉由如下等方法而提高：於經由接著劑61將防漏片材22a與外層不織布22b接著時，牢固地按壓，或者一面加溫一面按壓。 The shear strength of the outer layer composite sheet 22 can be improved by the following methods: when the leak-proof sheet 22a and the outer layer non-woven fabric 22b are bonded via the adhesive 61, press firmly, or press while heating.

又，寬度方向(X方向)上之防漏片材22a之拉伸強度較佳為100cN/25mm以上，更佳為150cN/25mm以上，又，較佳為400cN/25mm以下，更佳為300cN/25mm以下，較佳為100cN/25mm以上且400cN/25mm以下，更佳為150cN/25mm以上且300cN/25mm以下。該拉伸強度係如下所述般進行測定。首先，使用將接著劑溶解之溶劑、或者冷噴霧自尿布1將外層不織布22b、及防漏片材22a分離。將該分離後之防漏片材22a裁剪為長度方向(Y方向)設為25mm寬、寬度方向(X方向)設為約100mm寬的短條狀之樣本片。對於該樣本片，使用拉伸試驗機(Orientec股份有限公司之「Tensilon」RTC-1150A)，測量將樣本片向與尿布寬度方向(X方向)對應之朝向拉伸時之最大點負載，並將測得之最大點負載設為防漏片材22a之拉伸強度。此時，夾頭間隔係設為50mm，拉伸速度係設為300 mm/min。 Also, the tensile strength of the leakage preventing sheet 22a in the width direction (X direction) is preferably 100 cN/25mm or more, more preferably 150cN/25mm or more, and more preferably 400cN/25mm or less, more preferably 300cN/ 25 mm or less, preferably 100 cN/25 mm or more and 400 cN/25 mm or less, more preferably 150 cN/25 mm or more and 300 cN/25 mm or less. This tensile strength was measured as follows. First, the outer nonwoven fabric 22b and the leakage preventing sheet 22a are separated from the diaper 1 using a solvent in which an adhesive is dissolved or a cold spray. The leak-proof sheet 22a after this separation was cut out into a short strip-shaped sample piece having a width of 25 mm in the longitudinal direction (Y direction) and a width of about 100 mm in the width direction (X direction). For this sample sheet, a tensile tester (“Tensilon” RTC-1150A from Orientec Co., Ltd.) was used to measure the maximum point load when the sample sheet was stretched in the direction corresponding to the width direction (X direction) of the diaper, and the The measured maximum point load was set as the tensile strength of the leak-proof sheet 22a. At this time, the chuck gap was set to 50 mm, and the drawing speed was set to 300 mm/min.

又，外層不織布22b較佳為寬度方向(X方向)上之拉伸強度大於防漏片材22a。根據該構成，藉由將側片3向寬度方向之外方拉伸，即便於寬度方向上對外層不織布22b施加負載，亦能進一步抑制外層不織布22b於寬度方向上裂開。 Moreover, it is preferable that the tensile strength in the width direction (X direction) of the outer layer nonwoven fabric 22b is larger than that of the leakage preventing sheet 22a. According to this configuration, even if a load is applied to the outer layer nonwoven fabric 22b in the width direction by stretching the side sheet 3 outward in the width direction, the outer layer nonwoven fabric 22b can be further suppressed from being split in the width direction.

就更確實地發揮上述效果之觀點而言，寬度方向(X方向)上之外層不織布22b之拉伸強度較佳為300cN/25mm以上，更佳為400cN/25mm以上，又，較佳為1000cN/25mm以下，更佳為800cN/25mm以下，較佳為300cN/25mm以上且1000cN/25mm以下，更佳為400cN/25mm以上且800cN/25mm以下。外層不織布22b之拉伸強度可利用與上述防漏片材22a之拉伸強度相同之方法進行測定。 From the viewpoint of exerting the above-mentioned effects more reliably, the tensile strength of the outer layer nonwoven fabric 22b in the width direction (X direction) is preferably 300cN/25mm or more, more preferably 400cN/25mm or more, and more preferably 1000cN/ 25mm or less, more preferably 800cN/25mm or less, preferably 300cN/25mm or more and 1000cN/25mm or less, more preferably 400cN/25mm or more and 800cN/25mm or less. The tensile strength of the outer nonwoven fabric 22b can be measured by the same method as the tensile strength of the leak-proof sheet 22a described above.
