Moreover, the 2nd adhesive agent 3 may be arrange|positioned in the same pattern in the extension part which exceeds the side edge in the width direction Y of the lower side core material 14b, and the edge in the longitudinal direction X. In this case, the second adhesive 3 joins the skin-facing surface of the back sheet 15 to either or both of the front sheet 12 and the three-dimensional gather-forming sheet 16 in the extending portion. In addition, the 1st adhesive agent 2 and the 2nd adhesive agent 3 are terms used for the convenience of description of this invention, and the same adhesive agent may be used for the 1st adhesive agent 2 and the 2nd adhesive agent 3, and may use different types. the adhesive. As shown in FIG. 3, the diaper 1 has the back surface sheet 15 on the non-skin opposing surface side of the lower side core sheet 14b. The back sheet 15 of the diaper 1 is a laminate of a leak-proof sheet 15a containing a liquid-impermeable or liquid-impermeable resin film and a non-skin-facing non-woven fabric 15b covering the leak-proof sheet 15a. constituted by the body. In addition, the back sheet 15 in this invention may be comprised only by the leak-proof sheet 15a. As shown in FIGS. 3 and 4 , the first adhesive 2 is arranged in stripes. Specifically, between the lower core wrapping sheet 14b and the non-skin facing surface of the absorptive core 13, the first adhesive placement portion 20 where the first adhesive 2 is not placed and the first adhesive placement portion 20 where the first adhesive 2 is not placed are placed. The first adhesive agent non-arrangement portions 25 alternate in the width direction Y and extend in the longitudinal direction X, respectively. The second adhesive 3 is also arranged in stripes in the same manner. Specifically, between the lower core wrap sheet 14b and the back sheet 15, a second adhesive placement portion 30 where the second adhesive 3 is placed and a second adhesive non- placement portion where the second adhesive 3 is not placed are placed 35 alternate in the width direction Y and extend along the length direction X respectively. The length of the first adhesive placement portion 20 and the length of the second adhesive placement portion 30 in the width direction Y may be respectively fixed or not, but are preferably fixed as in the present embodiment. In addition, the length of the first adhesive non-disposition portion 25 and the length of the second adhesive non-disposition portion 35 in the width direction Y may be respectively fixed as shown in FIG. 3 and FIG. This embodiment is generally fixed.
下側包芯片材14b於寬度方向Y上具有複數個與吸收性芯體13及背面片材15均不接著之非接著部5。具體而言,非接著部5係尿布1中之第1接著劑非配置部25與第2接著劑非配置部35重疊之部分,該部分係第1接著劑2及第2接著劑3均不存在。又,複數個非接著部5與第1接著劑非配置部25及第2接著劑非配置部35同樣地分別沿長度方向X延伸。
The lower side core sheet 14b has a plurality of non-bonded portions 5 in the width direction Y that are not bonded to the absorptive core 13 and the back sheet 15. Specifically, the non-adhesive portion 5 is a portion of the diaper 1 where the first adhesive non-disposition portion 25 and the second adhesive agent non-disposition portion 35 overlap, and this portion is the portion where neither the first adhesive agent 2 nor the second adhesive agent 3 overlap. exist. In addition, the plurality of non-adhesive portions 5 extend in the longitudinal direction X, respectively, similarly to the first adhesive agent non-arrangement portion 25 and the second adhesive agent non-arrangement portion 35 .
下側包芯片材14b之非接著部5只要為不與第1接著劑配置部20重疊且亦不與第2接著劑配置部30重疊之部分,而且以沿長度方向X延伸之方式形成即可,第1接著劑非配置部25與第2接著劑非配置部35重疊之形態並無特別限制。即,非接著部5亦可形成第1接著劑配置部20彼此間、第2接著劑配置部30彼此間、及第1接著劑配置部20與第2接著劑配置部30之間之任一部位。
The non-bonded portion 5 of the lower core sheet 14b may be a portion that does not overlap with the first adhesive placement portion 20 and does not overlap with the second adhesive placement portion 30, and may be formed so as to extend in the longitudinal direction X. The form in which the first adhesive agent non-arrangement portion 25 and the second adhesive agent non-arrangement portion 35 overlap is not particularly limited. That is, the non-adhesive portion 5 may form any one between the first adhesive placement portions 20 , between the second adhesive placement portions 30 , and between the first adhesive placement portion 20 and the second adhesive placement portion 30 . part.
例如,亦可如圖6(a)之左側之非接著部5般,第1接著劑非配置部25與第2接著劑非配置部35完全重疊而形成非接著部5。第1接著劑非配置部25與第2接著劑非配置部35完全重疊係包括寬度方向Y上之第1接著劑非配置部25之兩端部之一者與第2接著劑非配置部35之兩端部之一者分別完全一致的情況、及寬度方向Y上之一接著劑非配置部之兩端部向較另一接著劑非配置部之兩側部更外側延伸的情況。
For example, like the non-bonded portion 5 on the left side of FIG. 6( a ), the non-bonded portion 5 may be formed by completely overlapping the first adhesive non-positioned portion 25 and the second adhesive non-positioned portion 35 . The first adhesive agent non-arrangement portion 25 and the second adhesive agent non-arrangement portion 35 completely overlap each other and include one of both ends of the first adhesive agent non-arrangement portion 25 in the width direction Y and the second adhesive agent non-arrangement portion 35 The case where one of the both ends is completely identical, and the case where the both ends of one adhesive non-positioning portion in the width direction Y extends to the outside of the both sides of the other adhesive non-positioning portion.
又,亦可如圖6(a)之右側之非接著部5般,兩接著劑非配置部25、35局部重疊而形成非接著部5。於該情形時,非接著部5形成於寬度方向Y上之第1接著劑配置部20或第2接著劑配置部30之兩側。
Moreover, like the non-bonding part 5 on the right side of FIG. 6( a ), the non-bonding part 5 may be formed by partially overlapping the two adhesive non-arranging parts 25 and 35 . In this case, the non-adhesive portion 5 is formed on both sides of the first adhesive placement portion 20 or the second adhesive placement portion 30 in the width direction Y.
根據本實施形態之尿布1,下側包芯片材14b具有與吸收性芯體13及背面片材15均不接合之非接著部5,因此下側包芯片材14b易於向寬度方向Y伸長,吸收體11吸收排泄液時,吸收體11易於作為整體而鼓起(參照圖7),亦不易產生阻礙吸水性聚合物或吸收體之膨潤之現象即膨潤阻礙。因此,有效地利用吸收性聚合物之吸收容量,吸收體11展現優異之吸收性能。
According to the diaper 1 of the present embodiment, since the lower core wrapping material 14b has the non-bonding portion 5 which is not bonded to the absorptive core 13 and the back sheet 15, the lower side core wrapping material 14b is easily stretched in the width direction Y and absorbs When the body 11 absorbs excretory fluid, the absorber 11 tends to bulge as a whole (refer to FIG. 7 ), and swelling inhibition, which is a phenomenon that hinders the swelling of the water-absorbent polymer or the absorber, is less likely to occur. Therefore, the absorption capacity of the absorbent polymer is effectively utilized, and the absorber 11 exhibits excellent absorption performance.
另一方面,若對下側包芯片材14b之肌膚對向面或非肌膚對向面之整個面滿塗佈接著劑,則存在吸收體11難以鼓起,或產生吸水性聚合物之膨潤阻礙,導致無法使吸收體11中之吸水性聚合物之吸收能力充分發揮之情況。
On the other hand, if the entire surface of the skin-opposing surface or the non-skin-opposing surface of the lower core wrapping sheet 14b is covered with adhesive, the absorber 11 is difficult to swell, or the swelling of the water-absorbing polymer is hindered. , resulting in the situation that the absorption capacity of the water-absorbent polymer in the absorber 11 cannot be fully exerted.
就吸收性芯體13、下側包芯片材14b及背面片材15之各構件於寬度方向Y上有效率地伸長之觀點、及容易形成非接著部5之觀點而言,較佳為與配置有第2接著劑3之第2接著劑配置部30相比,配置有第1接著劑2之第1接著劑配置部20於寬度方向Y上之配置間距較短。第1接著劑配置部20之配置間距Pa之長度如圖5(a)所示般,係寬度方向Y上之第1接著劑配置部20之長度Wa與第1接著劑非配置部25之長度Da之合計的長度。又,第2接著劑配置部30之配置間距Pb之長度如圖5(b)所示般,係寬度方向Y上之第2接著劑配置部30之長度Wb與第2接著劑非配置部35之長度Db之合計的長度。
From the viewpoint of efficiently extending each member of the absorptive core 13, the lower core sheet 14b, and the back sheet 15 in the width direction Y, and from the viewpoint of easily forming the non-bonded portion 5, it is preferable to arrange it with The arrangement pitch in the width direction Y of the first adhesive arrangement portion 20 in which the first adhesive 2 is arranged is shorter than that of the second adhesive arrangement portion 30 with the second adhesive 3 . As shown in FIG. 5( a ), the length of the arrangement pitch Pa of the first adhesive placement portion 20 is the length Wa of the first adhesive placement portion 20 in the width direction Y and the length of the first adhesive non-placed portion 25 The total length of Da. In addition, as shown in FIG. 5( b ), the length of the arrangement pitch Pb of the second adhesive arrangement portion 30 is the length Wb of the second adhesive arrangement portion 30 in the width direction Y and the second adhesive non-arrangement portion 35 .

As the second adhesive 3, a plurality of adhesives for bonding the lower core sheet and the back sheet with different adhesive strengths may be used. For example, as the second adhesive, it is preferable that the adhesive strength when wet is different between the adhesive arranged in the central region of the width direction Y and the adhesive arranged in the side regions sandwiching the central region, and more preferably In each of the side regions, an adhesive having a stronger adhesive strength when wet is arranged than the adhesive arranged in the central region. According to this configuration, when the absorber 11 is wetted by the excretion liquid, the central portion of the absorber 11 in the width direction Y is easily stretched in the width direction Y, and the swelling resistance of the absorber 11 can be further suppressed. The adhesion strength at the time of wetting is the adhesion strength under the assumption that the absorber 11 is in contact with the excretory fluid and is wetted. In addition, the magnitude|size of the adhesive strength at the time of wetting was confirmed by the method shown below. <Test for confirming the magnitude of adhesive strength> An arbitrary portion where the absorptive core 13 is present is cut along the width direction Y of the diaper 1, and the portion corresponding to the lower core wrapping material 14b of the cut surface is taken as the center It is gradually soaked with water using a sprayer. A force is applied in a direction in which the lower core wrapping material 14b and the back sheet 15 are peeled off, and it is checked whether the lower core wrapping material 14b and the back sheet 15 are peeled without being broken. This operation is repeated until the lower core sheet 14b and the back sheet 15 are completely peeled off. From the amount of water impregnation when the lower core sheet 14b and the back sheet 15 are completely peeled off, it is possible to judge the magnitude of the adhesive strength when wet. In this method, peeling of the lower core sheet 14b and the back sheet 15 occurs in the disposition area of the weak adhesive 3a with a small amount of water impregnation in the disposition area of the strong adhesive 3b. The weak adhesive 3a is preferably arranged in the central area M of the core material 14b on the lower side in the width direction Y, and the central area M is preferably arranged in the maximum length W14b of the core material 14b on the lower side in the width direction Y. The central area when divided into 3 areas equally. Moreover, it is preferable to arrange|position the strong adhesive agent 3b in the 2 areas on both sides when the maximum length W14b of the upper and lower side core material 14b in the width direction Y is divided into three equal parts. In the diaper 1, the back surface sheet 15 is provided with the leak-proof sheet 15a and the exterior nonwoven fabric 15b. As shown in FIGS. 3 and 4 , the leak-proof sheet 15a and the outer nonwoven fabric 15b are joined via the third adhesive 4 arranged in stripes. The third adhesive 4 is an adhesive for joining the leak-proof sheet 15a and the outer nonwoven fabric 15b. Furthermore, the third adhesive is also a term used for the convenience of explaining the present invention, and as the third adhesive, the same adhesive as the first or second adhesive described above may be used, or a different type of adhesive may be used. agent. The 3rd adhesive agent 4 is arrange|positioned at intervals in the width direction Y by the some 3rd adhesive agent arrangement|positioning part 40 in which the 3rd adhesive agent 4 is arrange|positioned. That is, the 3rd adhesive agent arrangement|positioning part 40 and the 3rd adhesive agent non-arrangement part 45 in which this 3rd adhesive agent 4 is not arrange|positioned are alternately formed in the width direction Y, and are respectively extended in the longitudinal direction X, and are formed. As shown in FIGS. 3 and 4 , the third adhesive placement portion 40 may be fixed or not, but preferably fixed as in the present embodiment. The third adhesive agent non-arrangement portion 45 exists between the third adhesive agent arrangement portions 40, and in this portion, the leakage preventing sheet 15a and the exterior nonwoven fabric 15b are not joined. Hereinafter, the region in which the third adhesive agent 4 is arranged in stripes, that is, the region including the third adhesive agent arrangement portion 40 and the third adhesive agent non-arrangement portion 45 is also referred to as a third stripe arrangement region 41 . When the leak-proof sheet 15a and the outer non-woven fabric 15b are joined by the third adhesive 4 arranged in stripes as described above, the outer non-woven fabric 15b and the outer non-woven fabric 15b can be kept while wearing (wearing) or during wearing. The joint strength of the drain sheet 15a softens the touch of the outer nonwoven fabric 15b, especially the non-skin-facing surface of the outer nonwoven fabric 15b. Moreover, when using the thing which has moisture permeability as the leak-proof sheet 15a, since the fall of moisture permeability can be suppressed, the diaper 1 can be made less likely to be stuffy. Moreover, when the 3rd adhesive agent non-arrangement part 45 and the said non-adhesive part 5 are overlapped in the planar view of the diaper 1 (absorbent article), the swelling inhibition of the said absorber 11 can be suppressed further. Hereinafter, the portion where the third adhesive agent non-arrangement portion 45 and the non-adhesive portion 5 overlap each other is also referred to as a non-adhesive overlapping portion 6 . In the non-adhesive repeating portion 6, the first adhesive agent 2, the second adhesive agent 3, and the third adhesive agent 4 do not exist.
