As described in detail, it is preferable that the upper surface adhesive 5U and the lower surface adhesive 5D are not applied only to the position corresponding to the constricted portion of the space portion 41c. In other words, it is preferable that the respective application regions of the upper surface adhesive 5U and the lower surface adhesive 5D are disposed in the space portion 41c of the both side portions 41s and 41s of the absorbent core portion 41 in the width direction (X direction). The apexes 41c1 and 41c1 of the (contracted portion) are formed in the longitudinal direction (Y direction) over the entire length (Y direction) of the absorbent core portion 41 (from the front side portion A to the back side portion B). Further, the apex 41c1 of the space portion 41c (contraction portion) which is formed in most of the front side portion A and the back side portion B is also located outside the width direction (X direction), and is not formed in addition to the other. region.
如上所述，接著劑5(上表面接著劑5U及下表面接著劑5D)並未塗佈於與吸收性芯部41之空間部41c(收縮部)對應之位置，因此，於吸收體4中，位於吸收性芯部41之空間部41c(收縮部)之上表面及下表面的包裹吸收性芯部41之被覆片材42彼此並未由接著劑5固定。具體而言，如圖2、圖 3所示，尿布1A中之上表面接著劑5U及下表面接著劑5D於較空間部41c(收縮部)之頂點41c1更靠寬度方向(X方向)外側之區域內並未自吸收性芯部41之腹側部A遍及背側部B而塗佈，因此位於吸收性芯部41之空間部41c(收縮部)之上表面(肌膚抵接面)之被覆片材42U與位於吸收性芯部41之空間部41c(收縮部)之下表面(非肌膚抵接面)之被覆片材42D未固定。 As described above, the adhesive 5 (the upper surface adhesive 5U and the lower surface adhesive 5D) is not applied to the position corresponding to the space portion 41c (contracted portion) of the absorbent core portion 41, and therefore, in the absorbent body 4 The covering sheets 42 covering the absorbent core portion 41 on the upper surface and the lower surface of the space portion 41c (contracted portion) of the absorbent core portion 41 are not fixed to each other by the adhesive 5. Specifically, as shown in Figure 2 As shown in Fig. 3, the upper surface adhesive 5U and the lower surface adhesive 5D in the diaper 1A are not self-absorbent in the region outside the width direction (X direction) of the apex 41c1 of the space portion 41c (contracted portion). Since the ventral side portion A of the 41 is applied to the back side portion B, the covering sheet 42U located on the upper surface (skin contact surface) of the space portion 41c (contracted portion) of the absorbent core portion 41 and the absorbent core portion are located. The coated sheet 42D on the lower surface (non-skin contact surface) of the space portion 41c (contracted portion) of 41 is not fixed.

若對下表面接著劑5D之塗佈區域進行詳細闡述，則於尿 布1B中，與上表面接著劑5U同樣，於寬度方向(X方向)上係遍及配設於吸收性芯部41之兩側部41s、41s之空間部41c(分割部413)之頂點41c1、41c1彼此之間而形成，且形成於一對側吸收性芯部412、412之非肌膚抵接面(下表面)，於長度方向(Y方向)上係遍及吸收性芯部41之長度方向(Y方向)之全長(自腹側部A遍及背側部B)而形成。於除此以外之區域、即空間部41c(分割部413)之頂點41c1與側吸收性芯部412之寬度方向(X方向)內側緣412s之間的區域內並未遍及吸收性芯部41之長度方向(Y方向)之全長(自腹側部A遍及背側部B)而形成，並未塗佈於與吸收性芯部41之空間部41c(分割部413)對應之位置。 If the coating area of the lower surface adhesive 5D is elaborated, then in the urine In the cloth 1B, similarly to the upper surface adhesive 5U, the apex 41c1 of the space portion 41c (divided portion 413) disposed on both side portions 41s and 41s of the absorbent core portion 41 is disposed in the width direction (X direction). 41c1 is formed between each other, and is formed on the non-skin contact surface (lower surface) of the pair of side absorbent core portions 412, 412, and extends in the longitudinal direction (Y direction) throughout the longitudinal direction of the absorbent core portion 41 ( The entire length of the Y direction) (from the ventral side A to the back side B). In the other region, that is, the region between the apex 41c1 of the space portion 41c (divided portion 413) and the inner edge 412s in the width direction (X direction) of the side absorbent core portion 412 does not extend over the absorbent core portion 41. The entire length (Y direction) is formed in the longitudinal direction (from the abdominal side A to the back side B), and is not applied to the position corresponding to the space portion 41c (divided portion 413) of the absorbent core portion 41.
如上所述，於尿布1B中，接著劑5(上表面接著劑5U及下表面接著劑5D)於空間部41c(分割部413)之頂點41c1與側吸收性芯部412之寬度方向(X方向)內側緣412s之間的區域內並未遍及吸收性芯部41之長度方向(Y方向)之全長(自腹側部A遍及背側部B)而塗佈，但就體液吸收後之吸收性芯部41不易變形之程度之觀點而言，較佳為僅不塗佈於與空間部41c(分割部413)對應之位置。 As described above, in the diaper 1B, the adhesive 5 (the upper surface adhesive 5U and the lower surface adhesive 5D) is in the width direction (X direction) of the apex 41c1 of the space portion 41c (the division portion 413) and the side absorbent core portion 412. The area between the inner side edges 412s is not applied over the entire length (Y direction) of the absorbent core portion 41 (from the front side portion A to the back side portion B), but the absorbent core after absorption by the body fluid From the viewpoint of the degree of deformation of the portion 41, it is preferable that it is not applied only to the position corresponding to the space portion 41c (the division portion 413).
如上所述，接著劑5(上表面接著劑5U及下表面接著劑5D)未塗佈於與吸收性芯部41之空間部41c(分割部413)對應之位置，故如圖6、圖7所示，尿布1B中之上表面接著劑5U及下表面接著劑5D於空間部41c(分割部413)之頂點41c1與側吸收性芯部412之寬度方向(X方向)內側緣412s之間的區域內未自吸收性芯部41之腹側部A遍及背側部B而塗 佈，因此位於吸收性芯部41之空間部41c(分割部413)之上表面(肌膚抵接面)之被覆片材42U與位於吸收性芯部41之空間部41c(分割部413)之下表面(非肌膚抵接面)之被覆片材42D未固定。 As described above, the adhesive 5 (the upper surface adhesive 5U and the lower surface adhesive 5D) is not applied to the space portion 41c (the division portion 413) of the absorbent core portion 41, and thus, as shown in FIGS. 6 and 7 As shown in the diaper 1B, the upper surface adhesive 5U and the lower surface adhesive 5D are between the apex 41c1 of the space portion 41c (the division portion 413) and the inner edge 412s of the width direction (X direction) of the side absorbent core portion 412. In the region, the ventral side portion A of the self-absorbent core portion 41 is coated over the back side portion B. Therefore, the cloth is located on the upper surface (skin contact surface) of the space portion 41c (divided portion 413) of the absorbent core portion 41 and the space portion 41c (divided portion 413) located in the absorbent core portion 41. The coated sheet 42D of the surface (non-skin contact surface) is not fixed.
吸收體4經由吸收體固定用接著劑6而固定於背面片材3，吸收體固定用接著劑6於尿布1B中係如圖6、圖7所示般塗佈於下襠部C之與吸收性芯部41之中央吸收性芯部411對應之位置。具體而言，吸收體4與背面片材3之間、即構成吸收體4之被覆片材42與背面片材3之間係塗佈吸收體固定用接著劑6而接合。若對吸收體固定用接著劑6之塗佈區域進行詳細闡述，則於尿布1B中，吸收體4與背面片材3接合並固定即可，但就容易發揮只有下述尿布1B才會產生之效果的觀點而言，於寬度方向(X方向)上係遍及下襠部C之與吸收性芯部41之中央吸收性芯部411對應之位置、即配設於吸收性芯部41之兩側部41s、41s之空間部41c(分割部413)之頂點41c1、41c1彼此之間而形成，於長度方向(Y方向)上係遍及吸收性芯部41之全長(自腹側部A遍及背側部B)而形成。 The absorber 4 is fixed to the back sheet 3 via the absorber fixing agent 6, and the absorber fixing agent 6 is applied to the lower jaw C and absorbed in the diaper 1B as shown in Figs. 6 and 7 . The central absorbent core 411 of the core portion 41 corresponds to the position. Specifically, between the absorber 4 and the back sheet 3, that is, between the covering sheet 42 constituting the absorber 4 and the back sheet 3, the absorber fixing agent 6 is applied and joined. When the application region of the adhesive fixing agent 6 is described in detail, the absorbent core 4 and the back sheet 3 may be joined and fixed in the diaper 1B, but it is easy to exhibit only the following diaper 1B. From the viewpoint of the effect, in the width direction (X direction), the position of the lower jaw portion C corresponding to the central absorbent core portion 411 of the absorbent core portion 41, that is, disposed on both sides of the absorbent core portion 41 is disposed. The vertices 41c1 and 41c1 of the space portion 41c (dividing portion 413) of the portions 41s and 41s are formed between each other, and extend over the entire length of the absorbent core portion 41 in the longitudinal direction (Y direction) (from the abdominal side portion A to the back side portion). Formed by B).
對使用上述本發明之第2實施形態之尿布1B時之作用效果進行說明。 The action and effect when the diaper 1B of the second embodiment of the present invention is used will be described.
關於第2實施形態之尿布1B之效果，針對與第1實施形態之尿布1A之效果之不同點進行說明。未特別說明之方面與尿布1A之效果相同，並適當應用尿布1A之效果之說明。 The effect of the diaper 1B of the second embodiment will be described with respect to the difference from the effect of the diaper 1A of the first embodiment. The effect of the diaper 1A is the same as that of the diaper 1A, and the description of the effect of the diaper 1A is suitably applied.
尿布1B之接著劑5(上表面接著劑5U及下表面接著劑5D) 未塗佈於與吸收性芯部41之空間部41c(分割部413)對應之位置，於吸收體4中，位於吸收性芯部41之空間部41c(分割部413)之上表面之被覆片材42U與位於空間部41c(分割部413)之下表面之被覆片材42D未由接著劑5固定。又，尿布1B之吸收體固定用接著劑6塗佈於下襠部C之與吸收性芯部41之中央吸收性芯部411對應之位置。因此，如圖8所示，於尿布1B之使用中，即便作為吸收性芯部41之中央吸收性芯部411吸收穿戴者之體液而膨脹，亦不易阻礙中央吸收性芯部411之膨脹，進而，即便一對側吸收性芯部412、412吸收穿戴者之體液而膨脹，一對側吸收性芯部412、412亦可一面膨脹，一面向中央吸收性芯部411側移動，故不易阻礙側吸收性芯部412之膨脹，而使吸收體4中所含之吸收性聚合物原本之吸收力得以充分發揮，從而提高防漏性。 Adhesive 5 of diaper 1B (upper surface adhesive 5U and lower surface adhesive 5D) The coated sheet is placed on the upper surface of the space portion 41c (divided portion 413) of the absorbent core portion 41 in the absorbent body 4 at a position corresponding to the space portion 41c (divided portion 413) of the absorbent core portion 41. The material 42U and the covering sheet 42D located on the lower surface of the space portion 41c (dividing portion 413) are not fixed by the adhesive 5. Further, the absorber fixing agent 6 for the diaper 1B is applied to a position of the crotch portion C corresponding to the central absorbent core portion 411 of the absorbent core portion 41. Therefore, as shown in Fig. 8, in the use of the diaper 1B, even if the central absorbent core portion 411 as the absorbent core portion 41 absorbs the body fluid of the wearer and expands, it is less likely to impede the expansion of the central absorbent core portion 411. Even if the pair of side absorbent core portions 412, 412 absorb the body fluid of the wearer and expand, the pair of side absorbent core portions 412, 412 can be expanded while moving toward the center of the central absorbent core portion 411, so that it is difficult to block the side. The expansion of the absorbent core portion 412 allows the absorption force of the absorbent polymer contained in the absorbent body 4 to be sufficiently exerted, thereby improving the leakproofness.

Then, the absorbent core of Example 2 was prepared by wrapping the absorbent core coated with the adhesive as a toilet paper (basis weight: 13.5 g/m 2 ) as a coated sheet.
比較例1中係使用與上述實施例1相同之吸收性芯部。將與實施例1相同之接著劑以達到塗敷量6 g/m2之方式塗敷於與實施例1相同之衛生紙之整個面，以塗敷接著劑後之衛生紙包裹吸收性芯部，從而製作比較例1之吸收體。 In Comparative Example 1, the same absorbent core as in the above Example 1 was used. The same adhesive as in Example 1 was applied to the entire surface of the same toilet paper as in Example 1 in such a manner that the coating amount was 6 g/m 2 , and the absorbent core was wrapped with the toilet paper after the application of the adhesive, thereby The absorbent of Comparative Example 1 was produced.
比較例2中係使用與上述實施例2相同之吸收性芯部。將與實施例2相同之接著劑以達到塗敷量6 g/m2之方式塗敷於與實施例2相同之衛生紙之整個面，以塗敷接著劑後之衛生紙包裹吸收性芯部，從而製作比較例2之吸收體。 In Comparative Example 2, the same absorbent core as in the above Example 2 was used. The same adhesive as in Example 2 was applied to the entire surface of the same toilet paper as in Example 2 in such a manner that the coating amount was 6 g/m 2 , and the absorbent core was wrapped with the toilet paper after the application of the adhesive, thereby The absorbent of Comparative Example 2 was produced.
針對所製作之各吸收體，藉由以下之方法分別評價回滲量(人工尿分批注入時)。又，以目測觀察人工尿全量注入後之洩漏。將該等結果示於下述表1。 The amount of rewet (in the case of artificial urine batch injection) was evaluated for each of the produced absorbent bodies by the following methods. Further, the leakage after the full injection of artificial urine was visually observed. These results are shown in Table 1 below.
於將各吸收體固定於水平面上之狀態下，使吸收體之中心部吸收人工尿40 g，放置10分鐘，進而吸收人工尿40 g。重複該操作，注入合計80 g之人工尿。繼而，於人工尿之吸收部位上重疊Advantec製造之70 mm×70 mm尺寸之濾紙16張，進而於其上放置100 mm×100 mm之3.5 kg之砝碼。經過2分鐘後，除去砝碼，測定吸收人工尿後之濾紙之重量。自該重量減去吸收前之濾紙之重量，將該值作為回滲量。 In the state in which the respective absorbers were fixed to the horizontal surface, 40 g of artificial urine was absorbed in the center portion of the absorbent body, and left for 10 minutes to absorb 40 g of artificial urine. This operation was repeated to inject a total of 80 g of artificial urine. Then, 16 sheets of 70 mm × 70 mm size filter paper manufactured by Advantec were placed on the absorption portion of the artificial urine, and a weight of 3.5 kg of 100 mm × 100 mm was placed thereon. After 2 minutes, the weight was removed, and the weight of the filter paper after the artificial urine was absorbed was measured. The weight of the filter paper before absorption is subtracted from the weight, and this value is taken as the amount of rewet.
由表1之結果明確可知，與比較例1之吸收體相比，實施例1之吸收體之回滲量較少，可充分發揮吸收體中所含之吸收性聚合物原本之吸收力，洩漏次數亦較少。若使用此種實施例1之吸收體而製作拋棄式尿布，則使用實施例1之吸收體而製作之尿布與使用比較例1之吸收體而製作之尿布相比，可期待防漏性提高。 As is clear from the results of Table 1, the absorbent of Example 1 has a smaller amount of rewet than the absorbent of Comparative Example 1, and the original absorbent force of the absorbent polymer contained in the absorbent body can be sufficiently exhibited and leaked. The number of times is also small. When the disposable diaper was produced using the absorbent body of the first embodiment, the diaper produced by using the absorbent body of the first embodiment was expected to have improved leakproofness as compared with the diaper produced by using the absorbent of the comparative example 1.
又，由表1之結果明確可知，與比較例2之吸收體相比，實施例2之吸收體之回滲量較少，可充分發揮吸收體中所含之吸收性聚合物原本之吸收力，洩漏次數亦較少。若使用此種實施例2之吸收體而製作拋棄式尿布，則使用實施例2之吸收體而製作之尿布與使用比較例2之吸收體而製作之尿布相比，可期待防漏性提高。 Moreover, as is clear from the results of Table 1, the absorbent body of Example 2 has a smaller amount of rewet than the absorbent of Comparative Example 2, and the original absorbent force of the absorbent polymer contained in the absorbent body can be sufficiently exhibited. The number of leaks is also small. When the disposable diaper was produced using the absorbent body of the second embodiment, the diaper produced by using the absorbent of the second embodiment was expected to have improved leakproofness as compared with the diaper produced by using the absorbent of the comparative example 2.
根據本發明之拋棄式尿布，可使吸收體中所含之吸收性聚合物原本之吸收力得以充分發揮，從而提高防漏性。 According to the disposable diaper of the present invention, the absorption force of the absorbent polymer contained in the absorbent body can be sufficiently exerted to improve the leakproofness.
