Abstract
Description
本發明係關於在2片薄片材之間將彈性構件以伸展狀態配置的吸收性物品及吸收性物品之製造方法。 The present invention relates to an absorbent article and a method for producing an absorbent article in which an elastic member is disposed in an extended state between two sheets.
專利文獻1揭示有,在腿圍開口部的周圍設置伸展後的彈性構件之吸收性物品。該吸收性物品之製造方法,係以使吸收性物品之左側的腿圍彈性構件和右側的腿圍彈性構件連續的方式在薄片材上以伸展狀態配置彈性構件,切斷該左側的腿圍彈性構件和右側的腿圍彈性構件之間不要的彈性構件。如此製造的吸收性物品,左側的腿圍彈性構件和右側的腿圍彈性構件成為非連續地配置。 Patent Document 1 discloses an absorbent article in which an elastic member after stretching is provided around a leg opening portion. In the method for producing an absorbent article, the elastic member is disposed on the sheet in an extended state such that the leg elastic member on the left side of the absorbent article and the leg elastic member on the right side are continuous, and the leg elasticity of the left side is cut. An unnecessary elastic member between the member and the right leg elastic member. In the absorbent article thus produced, the left leg elastic member and the right leg elastic member are disposed discontinuously.
如此地,以往係將連續的彈性構件以伸展狀態配置於薄片材,且切斷彈性構件的一部分,藉此僅在必要部分(例如,腿部開口部的周圍)設置彈性構件。 As described above, in the related art, a continuous elastic member is disposed in a stretched state on the sheet material, and a part of the elastic member is cut, whereby the elastic member is provided only in a necessary portion (for example, around the leg opening portion).
[專利文獻1]美國專利公報第6482278號公報 [Patent Document 1] US Patent Publication No. 6482278
但是,上述吸收性物品有以下問題。 However, the above absorbent article has the following problems.
若欲在製造過程連續地將彈性構件以伸展狀態配置後切斷彈性構件而呈非連續地配置彈性構件,則在切斷彈性構件時,切斷部分的彈性構件之伸展狀態被解除而產生收縮。因此,彈性構件的端部朝比切斷位置更靠伸展方向內側移動。若該彈性構件的端部之移動量變長,則在切斷部分附近成為未配置彈性構件,無法使切斷部分附近的薄片材等收縮。 If the elastic member is to be disposed in an extended state and the elastic member is continuously cut in the manufacturing process, the elastic member is discontinuously disposed, and when the elastic member is cut, the stretched state of the elastic member of the cut portion is released and contracted. . Therefore, the end portion of the elastic member moves toward the inner side in the extending direction from the cutting position. When the amount of movement of the end portion of the elastic member is increased, the elastic member is not disposed in the vicinity of the cut portion, and the sheet material or the like in the vicinity of the cut portion cannot be shrunk.
例如,為了使切斷部分附近的薄片材等收縮,可考慮在切斷部分的彈性構件、薄片材的切斷部分塗布接著劑。但是,若在切斷部分的彈性構件等塗布接著劑,則有接著劑從切斷部分露出之虞。若接著劑從切斷部分露出,則有薄片材彼此在非意圖部分接合、或接著劑附著於穿用者而產生肌膚問題之虞。 For example, in order to shrink a sheet or the like in the vicinity of the cut portion, it is conceivable to apply an adhesive to the elastic member of the cut portion or the cut portion of the sheet. However, when an adhesive is applied to the elastic member or the like in the cut portion, the adhesive is exposed from the cut portion. When the adhesive is exposed from the cut portion, the sheet material is joined to each other at an unintentional portion, or the adhesive adheres to the wearer to cause a skin problem.
又,為了使切斷部分附近的薄片材等收縮,可考慮將用來接合彈性構件和薄片材的接著劑之基重整體提高,以抑制彈性構件從薄片材分離移動。但是,若過度提高接著劑的基重整體,則有薄片材的柔軟性降低使得穿用時產生異樣感、或不易服貼於身體之虞。 Moreover, in order to shrink the sheet material or the like in the vicinity of the cut portion, it is conceivable to increase the basis weight of the adhesive for joining the elastic member and the sheet member as a whole to suppress separation and movement of the elastic member from the sheet member. However, if the basis weight of the adhesive is excessively increased as a whole, the softness of the sheet material is lowered to cause a strange feeling when worn, or to be difficult to adhere to the body.
因此,本發明之目的在於提供一種吸收性物品及吸收性物品之製造方法,該吸收性物品,係於2片薄 片材間配置有伸展狀態的彈性構件以藉由彈性構件使薄片材收縮,能邊保持薄片材的柔軟性、邊藉由彈性構件使薄片材所意圖的區域收縮。 Accordingly, it is an object of the present invention to provide an absorbent article and a method of producing an absorbent article which are attached to two sheets of thin An elastic member in an extended state is disposed between the sheets to shrink the sheet by the elastic member, and the area intended for the sheet is contracted by the elastic member while maintaining the flexibility of the sheet.

The central elastic material 44 is convex in the inward direction IN, and is formed so as to overlap the absorber 40 in the front-rear direction even if the absorber 40 is curved convexly toward the wearer. Since the central elastic member 44 is disposed to overlap the center slit 45, the center slit 45 can be more stably bent upward (on the wearer side). The central elastic material 44 is disposed in an extended state in the center in the width direction of the absorbent article in the front-rear direction. The central elastic material 44 is disposed in the crotch region S3.

第5圖係吸收體40之俯視圖。如第5圖所示,吸收體40具有第1層41和與第1層41重疊的第2層42。第1層41位於穿用者的非肌膚抵接面側,第2層42位於穿用者的肌膚抵接面側。 Fig. 5 is a plan view of the absorber 40. As shown in Fig. 5, the absorber 40 has a first layer 41 and a second layer 42 that overlaps with the first layer 41. The first layer 41 is located on the non-skin contact surface side of the wearer, and the second layer 42 is located on the wearer's skin contact surface side.
第1層41前後方向的長度比第2層42前後方向的長度更長。第1層41係配置成橫跨後腹圍區域S2、***區域S3及前腹圍區域S1,第2層42係配置成橫跨***區域S3和前腹圍區域S1。第2層42寬度方向的長度比第1層41寬度方向的長度更短。第1層41比第2層42更朝寬度方向外側突出。 The length of the first layer 41 in the front-rear direction is longer than the length of the second layer 42 in the front-rear direction. The first layer 41 is disposed so as to straddle the posterior abdominal region S2, the crotch region S3, and the front abdominal region S1, and the second layer 42 is disposed to straddle the crotch region S3 and the front abdominal region S1. The length of the second layer 42 in the width direction is shorter than the length of the first layer 41 in the width direction. The first layer 41 protrudes outward in the width direction from the second layer 42.
第1層41和第2層42係由綿狀紙漿和高分子吸收性聚合物(SAP)所構成。 The first layer 41 and the second layer 42 are composed of a cotton pulp and a polymer absorbent polymer (SAP).
第1層41例如可使紙漿100~500g/m2和SAP20~500g/m2混合形成。本實施形態之第1層41,係使紙漿280g/m2和SAP170g/m2混合所形成。 The first layer 41 can be formed, for example, by mixing 100 to 500 g/m 2 of pulp and 20 to 500 g/m 2 of SAP. Aspect of this embodiment the first layer 41, the pulp-based 280g / m 2 and SAP170g / m 2 formed by mixing.
在第1層41形成有中央縫隙45和一對側縫隙46。中央縫隙45形成於寬度方向W的中央部。中央縫隙45之前後方向的長度,比側縫隙46前後方向的長度更長。本實施形態中,中央縫隙的寬度為40mm,側縫隙46的寬度各為10mm。 A center slit 45 and a pair of side slits 46 are formed in the first layer 41. The center slit 45 is formed in the center portion in the width direction W. The length of the center slit 45 in the front-rear direction is longer than the length of the side slit 46 in the front-rear direction. In the present embodiment, the width of the center slit is 40 mm, and the width of the side slits 46 is 10 mm each.
第2層42例如可使紙漿100~500g/m2和SAP0~500g/m2混合形成。本實施形態之第2層42係使紙漿260g/m2和SAP160g/m2混合所形成。 Second layer 42 can, for example, pulp 100 ~ 500g / m 2 and SAP0 ~ 500g / m 2 formed by mixing. Based layer 42 of the present embodiment of the second aspect of the pulp 260g / m 2 and SAP160g / m 2 formed by mixing.
第2層42為沙漏形狀。第2層42的前後方向中央部係寬度方向的長度形成為較短的狹寬部42N。該狹寬部42N的外側端部和側縫隙46的內側端部為一致。根據這種構造,能在側縫隙46的寬度方向端部形成吸收體40的剛性差,而能以側縫隙46為基點使吸收體穩定地彎曲。 The second layer 42 is in the shape of an hourglass. The length of the center portion in the front-rear direction of the second layer 42 in the width direction is formed into a short narrow portion 42N. The outer end portion of the narrow portion 42N and the inner end portion of the side slit 46 are identical. According to this configuration, the rigidity difference of the absorber 40 can be formed at the end portion in the width direction of the side slit 46, and the absorber can be stably bent with the side slit 46 as a base point.
又,藉由在側縫隙46使表面薄片10和吸收體裏面薄片30貼合並固定,能使吸收體彎曲且外型不會走樣。 Further, by attaching and fixing the surface sheet 10 and the sheet 3 of the absorbent body in the side slits 46, the absorber can be bent and the outer shape can be prevented from being aliased.
進一步,如第2圖所示,在寬度方向,第二薄片15的端部位於比側縫隙更靠內側。配置有第二薄片15的區域、和未配置第二薄片15的區域(比第二薄片15寬度方向的端部更靠寬度方向外側的區域)之剛性相異。 藉由設置有無第二薄片所致之剛性差,較容易以由側縫隙46構成的側彎曲部為基點進行彎曲。 Further, as shown in Fig. 2, the end portion of the second sheet 15 is located further inside than the side slit in the width direction. The rigidity of the region in which the second sheet 15 is disposed and the region in which the second sheet 15 is not disposed (the region on the outer side in the width direction from the end portion in the width direction of the second sheet 15) are different. By providing the difference in rigidity due to the presence or absence of the second sheet, it is easier to bend with the side bent portion composed of the side slits 46 as a base point.
又,藉由形成中央縫隙45,能使吸收體40的中央部分較容易朝穿用者側亦即內方向IN彎曲成凸狀。側縫隙46比中央縫隙45形成在更靠寬度方向外側。側縫隙46具有沿著前後方向延伸的縱長形狀。一對側縫隙46係以朝外方向OUT呈凸狀,亦即使吸收體40彎曲成與中央縫隙45相反的凸狀之方式,沿著前後方向形成於吸收體40。 Further, by forming the center slit 45, the central portion of the absorber 40 can be easily bent into a convex shape toward the wearer side, that is, the inner direction IN. The side slits 46 are formed on the outer side in the width direction than the center slits 45. The side slit 46 has an elongated shape extending in the front-rear direction. The pair of side slits 46 are convex in the outward direction OUT, and are formed in the absorber 40 along the front-rear direction even if the absorber 40 is curved in a convex shape opposite to the center slit 45.
在***區域S3,第2層42寬度方向的外側端部42W係與第1層的側縫隙46的內側端部41W重疊,沿著前後方向配置。比第2層42的外側端部42W更靠寬度方向外側係僅藉由第1層41構成,比外側端部42W更靠內側係去除形成有中央縫隙45的部分,藉由第1層41和第2層42構成。因此,將第1層41的內側端部41W和第2層42的外側端部42W作為交界,使吸收體40的剛性及厚度變化。本實施形態係以剛性等變化的第2層的外側端部42W作為交界,使吸收體彎曲。 In the crotch region S3, the outer end portion 42W in the width direction of the second layer 42 overlaps the inner end portion 41W of the side slit 46 of the first layer, and is disposed along the front-rear direction. The outer side end portion 42W of the second layer 42 is formed only by the first layer 41 on the outer side in the width direction, and the portion in which the center slit 45 is formed is removed from the outer end portion 42W, and the first layer 41 and The second layer 42 is constructed. Therefore, the inner end portion 41W of the first layer 41 and the outer end portion 42W of the second layer 42 are used as a boundary to change the rigidity and thickness of the absorber 40. In the present embodiment, the outer end portion 42W of the second layer which changes in rigidity or the like is used as a boundary to bend the absorber.
第6圖係將拋棄式紙尿布1的穿用狀態示意顯示之剖視圖(第1圖的X1-X’1線為基準)。拋棄式紙尿布1被穿用時,吸收體的***區域S3抵接於穿用者的胯間。藉由穿用者的腿等,在吸收體施加從寬度方向外側朝 向寬度方向內側的力量。吸收體40係以中央彈性材44及中央縫隙45、和側縫隙46作為基點使吸收體40彎曲,沿著拋棄式紙尿布1寬度方向W的剖面形狀係呈波浪狀變形。因此,吸收體40的***區域S3變成規則地折疊狀態。 Fig. 6 is a cross-sectional view schematically showing the wearing state of the disposable diaper 1 (based on the line X1-X'1 in Fig. 1). When the disposable diaper 1 is worn, the crotch region S3 of the absorbent body abuts against the wearer's crotch. By the wearer's leg or the like, the absorber is applied from the width direction to the outside The force to the inside of the width direction. In the absorber 40, the absorber 40 is bent by the center elastic material 44, the center slit 45, and the side slit 46 as a base point, and the cross-sectional shape of the disposable diaper 1 in the width direction W is wave-shaped. Therefore, the crotch region S3 of the absorber 40 becomes a regularly folded state.
吸收體40係使藉由中央彈性材44朝內方向IN呈凸狀的吸收體40之頂面抵接於穿用者的胯間部。形成由彎曲部所形成的凸狀部分之部分係僅藉由第2層42構成,厚度較薄。另一方面,由彎曲部形成的凸狀部分和由側縫隙形成的凸狀部分之間,重疊有第1層41和第2層42,厚度較厚且剛性高。可藉由彎曲部和側縫隙之間剛性高的部分支撐由彎曲部形成的凸狀部分,能使彎曲部形成的凸形狀之穩定性提昇。 The absorber 40 is in contact with the top surface of the wearer's crotch portion by the top surface of the absorber 40 which is convex in the inward direction IN by the central elastic material 44. The portion where the convex portion formed by the curved portion is formed is formed only by the second layer 42 and has a small thickness. On the other hand, between the convex portion formed by the curved portion and the convex portion formed by the side slit, the first layer 41 and the second layer 42 are overlapped, and the thickness is thick and the rigidity is high. The convex portion formed by the curved portion can be supported by the portion having high rigidity between the curved portion and the side slit, so that the stability of the convex shape formed by the curved portion can be improved.
又,穿用者兩腿合攏時,拋棄式紙尿布1的剖面形狀係吸收體在彎曲部及側縫隙折疊,以互相緊貼的狀態精簡地配置於胯間部下方。 Further, when the wearer's legs are closed, the cross-sectional shape of the disposable disposable diaper 1 is such that the absorbent body is folded in the curved portion and the side slit, and is placed in a state of being close to each other in a state of being closely attached to each other.
此時,藉由中央彈性材44及中央縫隙45所形成的彎曲部,位於與穿用者的胯間部抵接之位置。另一方面,藉由側縫隙46形成的彎曲部係於非肌膚抵接面側呈凸狀,位於不易與穿用者的***口抵接之位置。 At this time, the curved portion formed by the central elastic material 44 and the center slit 45 is located at a position in contact with the inter-turn portion of the wearer. On the other hand, the curved portion formed by the side slits 46 is convex on the non-skin contact surface side, and is located at a position where it is hard to abut against the wearer's excretory opening.
由於吸收體緊貼於穿用者的胯間部,即使像是沿著肌膚流動這種尿速緩慢的尿排出時,亦能防止體液漏出。又,於折疊狀態,在吸收體之與肌膚分離的部分之彎曲部,由於形成朝前後方向延伸的凹陷,能使體液朝前 後方向外側擴散,而能防止側漏。 Since the absorbent body is in close contact with the wearer's intercondyle, it is possible to prevent leakage of body fluid even when the urine flowing slowly along the skin is discharged. Further, in the folded state, in the curved portion of the portion of the absorbent body that is separated from the skin, the body fluid is made to face forward by forming a depression extending in the front-rear direction. It spreads to the outside in the back direction and prevents side leakage.
由於以形成在吸收體的中央縫隙45、側縫隙46為基點折曲,相較於在吸收體40形成厚度薄的部分作為凸狀部分之情形,即使吸收體40吸收液體而膨脹時,吸收體40仍容易彎曲。又,穿用拋棄式紙尿布1而使得吸收體40變形時的剖面形狀,係從非肌膚抵接面側向肌膚抵接面側變窄的漸細形狀。因此,容易收納於穿用者的胯間部之間隙而不會賦予異樣感。 Since the central slit 45 and the side slit 46 formed in the absorbent body are bent at the base point, compared with the case where the thin portion is formed as the convex portion in the absorbent body 40, the absorbent body 40 is expanded even if the absorbent body 40 absorbs the liquid. 40 is still easy to bend. Moreover, the cross-sectional shape when the absorbent body 40 is deformed by wearing the disposable disposable diaper 1 is a tapered shape which is narrowed from the non-skin contact surface side toward the skin contact surface side. Therefore, it is easy to accommodate in the gap of the wearer's crotch portion without giving a strange feeling.
又,藉由彎曲部形成的凸狀部分係僅由第2層42構成,厚度比第1層41和第2層42積層所構成的部分更薄。亦即,藉由彎曲部形成的凸狀部分,由於厚度薄且高度高,因此容易***胯間部狹窄的間隙,而容易與***口緊貼。因此,排尿口和吸收體緊貼,所以能迅速地吸收***的尿。又,在穿用者胯間部肌膚附近的部分,由於吸收體的厚度薄,可在離肌膚遠的部分折疊成厚度變厚,因而能使其服貼而無異樣感。 Further, the convex portion formed by the curved portion is composed only of the second layer 42 and has a thickness thinner than a portion formed by laminating the first layer 41 and the second layer 42. In other words, since the convex portion formed by the curved portion is thin and has a high height, it is easy to be inserted into a narrow gap between the crotch portions, and is likely to be in close contact with the excretory opening. Therefore, the urination mouth and the absorbent body are in close contact, so that the excreted urine can be quickly absorbed. Further, in the portion near the skin of the wearer's ankle, since the thickness of the absorbent body is thin, the thickness of the absorbent body can be folded to a greater extent from the skin, so that it can be worn without any abnormality.
又,在第1層和第2層兩方設置有開口部或側縫隙時,會有使第1層和第2層重疊時產生位置偏移之情形。例如,在寬度方向產生位置偏時,配置於左右的一對側縫隙的寬度變窄,無法規則地變形,而成為左右不平衡的吸收體,會有對吸收性和穿著感造成不良影響之虞。但是,藉由在第1層和第2層當中的任一者設置開口部或側縫隙,能防止側縫隙等位置偏移。 Further, when an opening or a side slit is provided in both the first layer and the second layer, a positional shift occurs when the first layer and the second layer are overlapped. For example, when the positional deviation occurs in the width direction, the width of the pair of side slits disposed on the right and left sides is narrowed, and the inside of the pair of side slits is not deformed regularly, and the absorber is unbalanced to the left and right, which may adversely affect the absorbability and wearing feeling. . However, by providing an opening or a side slit in any of the first layer and the second layer, it is possible to prevent positional displacement such as a side slit.

By such pressurization, the hind leg elastic material can be strongly bonded between the belt bodies. Then, the rear leg elastic material 5R projecting forward from the front end portion of the rear side outer top sheet strip 70RW or the rear outer back sheet strip 80RW, along the rear side outer top sheet strip 70RW The front end portion of the back side outer sheet strip body 80RW is cut off. Thereby, the rear leg elastic material 5R is disposed between the rear exterior top sheet 70R and the rear exterior back sheet 80R.
接著,根據第8圖及第9圖,詳細說明第1接著區域R1及第2接著區域R2。第9圖係將第8圖所示之接著區域示意顯示之剖視圖(以第2圖所示之X3-X’3線為基準)。 Next, the first succeeding region R1 and the second succeeding region R2 will be described in detail based on FIGS. 8 and 9. Fig. 9 is a cross-sectional view showing the succeeding region shown in Fig. 8 (based on the X3-X'3 line shown in Fig. 2).
第8圖(a)係顯示第2圖所示之展開圖中的第2接著區域R2和彈性材接著區域R11之圖。第2接著區域R2係設置成覆蓋前腿圍彈性材5F的後端部和後腿圍彈性材的前端部,且塗布有接著劑,用以將前腿圍彈性材5F的後端部和後腿圍彈性材的前端部確實地接合於外裝頂部薄片和外裝背部薄片之間。 Fig. 8(a) is a view showing the second succeeding region R2 and the elastic material following region R11 in the developed view shown in Fig. 2. The second following region R2 is provided to cover the rear end portion of the front leg elastic material 5F and the front end portion of the rear leg elastic material, and is coated with an adhesive for fixing the rear end portion of the front leg elastic material 5F and the rear portion. The front end portion of the leg-surrounding elastic material is surely joined between the exterior top sheet and the exterior back sheet.
第2接著區域R2係對於前側外裝頂部薄片及後側外裝頂部薄片以基重10g/m2塗布有熱熔型接著劑之區域。在第2接著區域R2,以藉由狹縫式塗布機方式之接觸塗布而塗布有接著劑。第2接著區域R2的塗布寬度為約20mm。 The second succeeding region R2 is a region in which the front side outer sheet and the rear side outer sheet are coated with a hot-melt type adhesive at a basis weight of 10 g/m 2 . In the second succeeding region R2, an adhesive is applied by contact coating by a slit coater method. The coating width of the second succeeding region R2 is about 20 mm.
在第2接著區域R2配置有前腿圍彈性材5F的後端部和後腿圍彈性材5R的前端部。第2接著區域R2 係分別設置於左右的腿圍彈性材,在寬度方向非連續地配置。此外,第2接著區域R2亦可在寬度方向連續。但是,藉由將第2接著區域R2非連續地設置,能抑制接著劑造成的外裝體之硬化,而確保外裝體的柔軟性。此外,第2接著區域的塗布圖型,不限定於本實施形態的形狀,例如也可以是條帶狀。 The rear end portion of the front leg elastic material 5F and the front end portion of the rear leg elastic material 5R are disposed in the second succeeding region R2. 2nd subsequent region R2 The leg elastic materials are respectively disposed on the left and right legs, and are disposed discontinuously in the width direction. Further, the second succeeding region R2 may be continuous in the width direction. However, by providing the second succeeding region R2 discontinuously, the curing of the exterior body by the adhesive can be suppressed, and the flexibility of the exterior body can be ensured. Further, the application pattern of the second succeeding region is not limited to the shape of the embodiment, and may be, for example, a strip shape.
前腹圍區域S1的第2接著區域R2係配置在比前側外裝頂部薄片70F的後端部更靠前方,後腹圍區域S2的第2接著區域R2係位於比後側外裝頂部薄片70R的前端部更後方。第2接著區域R2、與前側外裝頂部薄片70F的後端部或後側外裝頂部薄片70R的後端部之距離為5mm。 The second contiguous region R2 of the front abdominal region S1 is disposed further forward than the rear end portion of the front exterior top sheet 70F, and the second contiguous region R2 of the rear abdominal region S2 is positioned closer to the outer peripheral top sheet. The front end of the 70R is further rear. The distance between the second succeeding region R2 and the rear end portion of the front exterior top sheet 70F or the rear end portion of the rear exterior top sheet 70R is 5 mm.
狹縫式塗布機方式係接觸型的塗布方法,其塗布位置偏移比非接觸型塗布方法少。例如,若以非接觸型的螺旋方式塗布接著劑,外裝頂部薄片端部附近的接著劑會溢出,而有製造上產生不良情況之虞。但是,以接觸型的狹縫式塗布機方式塗布,能防止接著劑溢出。如此地,藉由使用接觸型的塗布方法,能在作為腿圍彈性材的切斷部位之外裝頂部薄片端部附近塗布接著劑,將腿圍彈性材固定於切斷部位附近。 The slit coater method is a contact type coating method in which the coating position shift is less than that of the non-contact type coating method. For example, when the adhesive is applied by a non-contact type spiral method, the adhesive in the vicinity of the end portion of the exterior top sheet may overflow, which may cause defects in manufacturing. However, it is applied by a contact type slit coater to prevent the adhesive from overflowing. As described above, by using the contact type coating method, the adhesive can be applied in the vicinity of the end portion of the top sheet which is the cut portion of the leg-surrounding material, and the leg-surrounding elastic material can be fixed in the vicinity of the cut portion.
彈性材接著區域R11係設置成覆蓋配置有腿圍彈性材的全部區域,且塗布有接著劑,用以將腿圍彈性材全體接合於外裝頂部薄片和外裝背部薄片之間。彈性材接著區域R11係從第2接著區域的上方被塗布有接著劑而 與第2接著區域R2的一部分重疊。 The elastic material following region R11 is provided so as to cover the entire area in which the leg-surrounding elastic members are disposed, and is coated with an adhesive for bonding the entire leg-surrounding elastic material between the exterior top sheet and the exterior back sheet. The elastic material subsequent region R11 is coated with an adhesive from above the second subsequent region. It overlaps with a part of the second following region R2.
彈性材接著區域R11係對於前側外裝頂部薄片70F及後側外裝頂部薄片70R以基重8g/m2塗布有熱熔型接著劑的區域。在彈性材接著區域R11以螺旋方式之非接觸塗布而塗布有接著劑。彈性材接著區域R11的塗布寬度係每一塗布嘴約18mm。藉由該塗布寬度沿著寬度方向朝前後方向塗布有複數列。 The elastic material following region R11 is a region in which the front side outer top sheet 70F and the rear side outer top sheet 70R are coated with a hot-melt type adhesive at a basis weight of 8 g/m 2 . An adhesive is applied to the elastic material following region R11 by a non-contact coating in a spiral manner. The coating width of the elastic material subsequent region R11 is about 18 mm per coating nozzle. The plurality of columns are applied in the front-back direction along the width direction by the coating width.
又,螺旋方式也有較上述例示者使振幅窄而使得每1條的塗布寬度窄,且使相鄰的螺旋熱熔之間隔窄的方式(複螺旋(Multi spiral)方式)。該複螺旋方式比通常螺旋方式對於塗布長度方向,具有寬度方向的塗布偏離少、不易產生間隙之特長,使用在本發明的重疊區域時,能減少彈性構件端部的偏離,具有使彈性構件端部的位置更為穩定這種優點。作為使用於重疊區域者,除了複螺旋方式以外,也可例示頂點塗布嘴(Summit nozzel)方式等。 Further, the spiral method has a mode in which the amplitude is narrower than the above-described example, and the coating width per one strip is narrow, and the interval between adjacent spiral heat fusions is narrow (multi-spiral method). The complex spiral method has less coating deviation in the width direction than the normal spiral method, and has a characteristic that the gap is less likely to occur in the width direction. When the overlap region of the present invention is used, the deviation of the end portion of the elastic member can be reduced, and the elastic member end can be made. The position of the department is more stable. As the overlap region, a Summit Nozzel method or the like can be exemplified in addition to the complex spiral method.
前腹圍區域S1的彈性材接著區域R11配置在比前側外裝頂部薄片70F的後端部更靠前方,後腹圍區域S2的彈性材接著區域R11配置在比後側外裝頂部薄片70R的前端部更靠後方。彈性材接著區域R11、與前側外裝頂部薄片70F的後端部或後側外裝頂部薄片的後端部之距離為10mm。 The elastic material following region R11 of the front abdominal region S1 is disposed further forward than the rear end portion of the front outer top sheet 70F, and the elastic material following region R11 of the rear abdominal region S2 is disposed at the outer peripheral top sheet 70R of the rear side. The front end is further rearward. The elastic material following region R11 has a distance of 10 mm from the rear end portion of the front exterior top sheet 70F or the rear end portion of the rear exterior top sheet.
螺旋方式係非接觸塗布,易受風的影響使得塗布位置容易偏移。但是,藉由使彈性材接著區域R11與 前側外裝頂部薄片70F的後端部或後側外裝頂部薄片的後端部分離10mm,能抑制接著劑從外裝薄片溢出,而抑制接著劑黏在穿用者的肌膚這種問題和製造線中的問題。 The spiral method is non-contact coating, which is susceptible to wind and makes the coating position easily offset. However, by making the elastic material follow the region R11 and The rear end portion of the front outer top sheet 70F or the rear end portion of the rear outer top sheet is separated by 10 mm, which can suppress the overflow of the adhesive from the outer sheet and suppress the adhesion of the adhesive to the wearer's skin. The problem in the line.
又,彈性材接著區域R11係設置成與接合前腹圍緣部4、4’和後腹圍緣部6、6’的接合部11不重疊。例如,若在接合部11塗布有接著劑,會有接合部11的密封強度(本實施形態中為超音波密封)降低的顧慮之故。 Further, the elastic material following region R11 is provided so as not to overlap the joint portion 11 of the joint front belly edge portions 4, 4' and the rear belly edge portions 6, 6'. For example, when the bonding agent is applied to the bonding portion 11, there is a concern that the sealing strength of the bonding portion 11 (the ultrasonic sealing in the present embodiment) is lowered.
再者,腿圍彈性材的伸展應力構成為,在腿圍彈性材全體並非均等,而是***區域側的伸展應力高,前腹圍區域側(或後腹圍區域側)的伸展應力低。因此,腿圍彈性材的接合部側的端部之伸展應力構成為較低。 Further, the extension stress of the leg-surrounding elastic material is such that the entire leg elastic material is not uniform, but the stretching stress on the side of the crotch region is high, and the stretching stress on the side of the front abdominal region (or the side of the rear abdominal region) is low. . Therefore, the tensile stress at the end portion on the joint side of the leg-surrounding elastic material is configured to be low.
由於如此地配置腿圍彈性材,將彈性材接著區域R11設置成與接合部11不重疊,即使於未能藉由彈性材接著區域R11覆蓋腿圍彈性材的接合部側的端部之情形,仍能防止腿圍彈性材的接合部側的端部之偏離。又,由於在腿圍彈性材的接合部側的端部附近配置有腹圍彈性材7A,即使於未能藉由腿圍彈性材使外裝體1B充分地收縮之情形,仍能藉由腹圍彈性材使外裝體1B收縮。 Since the leg-surrounding elastic material is disposed in this manner, the elastic material following region R11 is disposed so as not to overlap with the joint portion 11, even if the end portion of the leg-side elastic material on the joint portion side is not covered by the elastic material following region R11, It is still possible to prevent the deviation of the end portion on the joint side of the leg-surrounding elastic material. Further, since the abdominal elastic material 7A is disposed in the vicinity of the end portion on the joint portion side of the leg-surrounding elastic material, even if the outer casing 1B is not sufficiently shrunk by the leg-surrounding elastic material, it can still be abdomen The outer elastic material shrinks the outer casing 1B.
第8圖(b)係第2圖所示之展開圖中,顯示薄片接著區域R12之圖。薄片接著區域R12係塗布有接著劑用以接合外裝頂部薄片和外裝背部薄片。薄片接著區域R12係對於前側外裝背部薄片80F及後側外裝背部薄片80R以基重1.5g/m2塗布有熱熔型接著劑之區域。 Fig. 8(b) is a view showing the sheet following region R12 in the developed view shown in Fig. 2. The sheet following region R12 is coated with an adhesive for joining the outer top sheet and the outer back sheet. The sheet following region R12 is a region in which the front side outer back sheet 80F and the rear side outer back sheet 80R are coated with a hot-melt type adhesive at a basis weight of 1.5 g/m 2 .
在薄片接著區域R12,藉由控制縫(control seam)方式之非接觸塗布而塗布有接著劑。藉由控制縫方式能以較細的線徑以面狀薄塗布。因此,能保持外裝頂部薄片及外裝背部薄片的觸感,並且在外裝頂部薄片和外裝背部薄片之間不設置大的非接合部(浮起狀態)而無損外觀上的美觀。又,控制縫方式相較於螺旋方式能構成狹窄的塗布嘴(塗出口)間距,由於來自嘴間的塗布面難以形成間隙,因此不會產生薄片間不規則的大塊浮起,而能使外觀良好。如此地,較薄且以面狀塗布接著劑的方法,可例示Ω方式和頂點塗布嘴方式。 In the sheet subsequent region R12, an adhesive is applied by non-contact coating by a control seam method. By controlling the slit method, it can be coated in a thin surface with a thin wire diameter. Therefore, the tactile sensation of the exterior top sheet and the exterior back sheet can be maintained, and a large non-joining portion (floating state) is not provided between the exterior top sheet and the exterior back sheet without impairing the appearance. Further, the control slit method can form a narrow coating nozzle (coating outlet) pitch compared to the spiral method, and since it is difficult to form a gap between the coated surfaces from the nozzles, irregular large floating between the sheets does not occur, and Good appearance. As described above, the method of coating the adhesive agent in a thin and planar manner can be exemplified by the Ω method and the vertex coating nozzle method.
前腹圍區域S1的薄片接著區域R12配置在比前側外裝頂部薄片70F的後端部更靠前方,後腹圍區域S2的彈性材接著區域R11配置在比後側外裝頂部薄片70R的前端部更靠後方。薄片接著區域R12、與前側外裝頂部薄片70F的後端部或後側外裝頂部薄片70R的後端部之距離為8mm。 The sheet following region R12 of the front abdominal region S1 is disposed further forward than the rear end portion of the front exterior top sheet 70F, and the elastic material following region R11 of the rear abdominal region S2 is disposed at the outer peripheral top sheet 70R of the rear side. The front end is further rearward. The sheet following region R12 has a distance of 8 mm from the rear end portion of the front exterior top sheet 70F or the rear end portion of the rear exterior top sheet 70R.
薄片接著區域R12係與接合前腹圍緣部4、4’和後腹圍緣部6、6’的接合部11重疊。薄片接著區域R12,如上述般相較於彈性材接著區域R11之接著劑的基重低,其係為了對接合部11的密封強度給予較少的影響。此外,薄片接著區域R12亦可配置成與接合部11不重疊。 The sheet following region R12 overlaps the joint portion 11 of the joint front belly edge portions 4, 4' and the rear belly edge portions 6, 6'. The sheet following region R12 has a lower basis weight than the adhesive of the elastic material following region R11 as described above, in order to exert less influence on the sealing strength of the joint portion 11. Further, the sheet following region R12 may also be disposed so as not to overlap the joint portion 11.
第8圖(c)係顯示在外裝中心薄片100塗布有接著劑的中心接著區域R3之圖。中心接著區域R3 係包含以下區域之區域:塗布有接著劑用以接合外裝中心薄片100和前側外裝背部薄片80F(或後側外裝背部薄片80R)之區域;及塗布有接著劑用以接合外裝中心薄片100和前側外裝頂部薄片70F(或後側外裝頂部薄片70R)之區域。本實施形態中,外裝中心薄片100係經由中心接著區域R3,接合於前側外裝頂部薄片70F的後端部和後側外裝頂部薄片70R的前端部。 Fig. 8(c) is a view showing a center-adjacent region R3 in which the exterior center sheet 100 is coated with an adhesive. Center followed by area R3 An area including an adhesive layer for bonding an outer center sheet 100 and a front outer back sheet 80F (or a rear outer back sheet 80R); and an adhesive applied to join the outer center The area of the sheet 100 and the front side outer top sheet 70F (or the rear side outer top sheet 70R). In the present embodiment, the exterior center sheet 100 is joined to the front end portion of the front outer top sheet 70F and the front end portion of the rear outer top sheet 70R via the center rear region R3.
中心接著區域R3係對於外裝中心薄片100以基重8g/m2塗布有熱熔型接著劑之區域。在中心接著區域R3藉由狹縫式塗布機方式之接觸塗布而塗布有接著劑。相對於外裝中心薄片100、與前側外裝體或後側外裝體重疊的前後方向之長度30mm,中心接著區域R3的前後方向之長度為20mm。中心接著區域R3的前側及後側各自有各5mm未塗布有接著劑之非塗布區域。非塗布區域的前後方向之長度為5mm,由於相較於拋棄式紙尿布全體為較短的長度,例如於外裝中心薄片100的非塗布區域捲起之情形,仍無損外觀。特別是在最外側配置有外裝中心薄片之情形,能抑制外裝中心薄片之捲起。 The center succeeding region R3 is a region in which the exterior center sheet 100 is coated with a hot-melt type adhesive at a basis weight of 8 g/m 2 . An adhesive is applied to the center succeeding region R3 by contact coating by a slit coater method. The length of the center-to-back region R3 in the front-rear direction is 20 mm with respect to the length of the front-back direction of the exterior center sheet 100 and the front-side exterior body or the rear exterior body 30 mm. The front side and the rear side of the center succeeding region R3 each have a 5 mm non-coated region which is not coated with an adhesive. The length of the uncoated region in the front-rear direction is 5 mm, and since it is shorter than the entire disposable diaper, for example, in the case where the uncoated region of the outer center sheet 100 is rolled up, the appearance is not impaired. In particular, in the case where the outer center sheet is disposed on the outermost side, the winding of the outer center sheet can be suppressed.
外裝中心薄片100當中,與前側外裝背部薄片80F(或後側外裝背部薄片80R)重疊的區域係作為第3薄片材之功能,該第3薄片材係與第1接著區域和第2接著區域重疊的重疊區域R4重疊。 Among the outer center sheets 100, a region overlapping the front outer back sheet 80F (or the rear outer back sheet 80R) functions as a third sheet, the third sheet and the first succeeding region and the second sheet. The overlapping regions R4 in which the regions overlap are then overlapped.
本實施形態中,使用基質聚合物為合成橡膠系(SIS)之熱熔接著劑作為接著劑。基質聚合物可使用 EVA(乙酸乙烯酯共聚物)之EVA系或聚烯烴等烯烴系之熱熔劑。但是,兼具接著力(黏性力)和凝聚力的基質聚合物以合成橡膠系之接著劑較佳。 In the present embodiment, a matrix polymer is a hot-melt adhesive of a synthetic rubber system (SIS) as an adhesive. Matrix polymer can be used An EVA based on EVA (vinyl acetate copolymer) or an olefin-based hot melt such as polyolefin. However, a matrix polymer having both an adhesive force (cohesive force) and a cohesive force is preferred as a synthetic rubber-based adhesive.
又,於彈性構件為天然橡膠或合成橡膠等扁平形狀之情形,以SEPS系等接著力優異者為佳,於彈性構件為彈性纖維等接著面積小之情形,以凝聚力高者為佳,合成橡膠系中亦以SIS或SBS者為期望。 In the case where the elastic member is a flat shape such as a natural rubber or a synthetic rubber, it is preferable that the adhesion is excellent such as SEPS, and when the elastic member is a small contact area such as an elastic fiber, it is preferable that the cohesive force is high, and the synthetic rubber is preferable. The department also expects SIS or SBS.
接著,根據第9圖說明彈性構件的接合狀態。後腿圍彈性材5R的前端部係於腿圍彈性材被切斷前的狀態,伸展至與後側外裝頂部薄片的前端部及前側外裝背部薄片的前端部一致為止。但是,腿圍彈性材被切斷時,腿圍彈性材的伸展狀態被解除。在後側外裝頂部薄片的前端部及前側外裝背部薄片的前端部,由於未設置第1接著區域及第2接著區域,後腿圍彈性材5R的前端部未接合於外裝薄片,因此後腿圍彈性材5R的前端部於切斷後朝伸展方向的內側(本實施形態中的後方側)收縮。 Next, the joined state of the elastic member will be described based on Fig. 9. The front end portion of the rear leg elastic member 5R is extended to a state before the leg-surrounding elastic material is cut, and is extended to match the front end portion of the rear outer top sheet and the front end portion of the front outer back sheet. However, when the leg-surrounding elastic material is cut, the stretched state of the leg-surrounding elastic material is released. The front end portion of the rear outer cover top sheet and the front end portion of the front outer cover back sheet are not provided with the first rear region and the second rear region, and the front end portion of the rear leg elastic member 5R is not joined to the outer sheet. The front end portion of the rear leg elastic member 5R is contracted toward the inner side in the extending direction (the rear side in the present embodiment) after the cutting.
收縮後的後腿圍彈性材5R的前端部51保持在第1接著區域R1和第2接著區域R2重疊的重疊區域R4。重疊區域R4係第1接著區域和第2接著區域重疊,接著劑的基重(比第1接著區域、第2接著區域)變高,接著力高。因此,在重疊區域R4能抑制後腿圍彈性材5R的前端部51之移動。如此地,藉由將後腿圍彈性材5R的前端部51配置在重疊區域R4,使腿圍彈性材以伸展狀態配置在意圖的位置,能藉由該彈性構件使意圖的區域的腿 圍開口部附近收縮。因此,能提高腿圍的服貼性。 The front end portion 51 of the rear leg elastic member 5R after contraction is held in the overlapping region R4 where the first succeeding region R1 and the second succeeding region R2 overlap. In the overlap region R4, the first succeeding region and the second succeeding region are overlapped, and the basis weight (ratio of the first succeeding region and the second succeeding region) of the adhesive becomes higher, and the force is higher. Therefore, the movement of the front end portion 51 of the rear leg elastic member 5R can be suppressed in the overlap region R4. In this manner, by arranging the distal end portion 51 of the rear leg elastic member 5R in the overlapping region R4, the leg-surrounding elastic member is placed in an intended position in an extended state, and the leg of the intended region can be made by the elastic member. Shrink around the opening. Therefore, the fit of the leg circumference can be improved.
如此地,配置有腿圍彈性材的區域當中,在腿圍彈性材的收縮力有較高作用的腿圍彈性材的端部(作為切斷部位的端部)被配置之部分,藉由設置重疊區域R4提高接著劑的基重,能有效地減少回切(cutback)造成腿圍彈性材的移動。 In the region in which the leg-surrounding elastic material is disposed, the end portion of the leg-surrounding elastic material (the end portion serving as the cutting portion) in which the contraction force of the leg-surrounding elastic material has a high function is disposed, by setting The overlap region R4 increases the basis weight of the adhesive, and can effectively reduce the movement of the leg elastic material caused by the cutback.
此外,本實施形態中,將腿圍彈性材的被切斷之端部附近的接著劑之基重構成為較高,比第1接著區域的基重更高、也比第2接著區域的基重更高地構成。但是,亦可將第1接著區域的基重構成為比第2接著區域的基重更高。 Further, in the present embodiment, the base of the adhesive in the vicinity of the cut end portion of the leg-surrounding elastic material is reconfigured to be higher than the basis weight of the first succeeding region and also higher than the base of the second succeeding region. Heavy composition. However, the basis of the first subsequent region may be reconstructed to be higher than the basis weight of the second subsequent region.
又,重疊區域R4為構成第1接著區域的彈性材接著區域R11和薄片接著區域R12當中,至少任一者和第2接著區域為重疊區域即可。再者,第1接著區域亦可僅藉由彈性材接著區域R11和薄片接著區域R12的任一者構成。 Further, the overlapping region R4 may be an overlapping region of at least one of the elastic material following region R11 and the sheet following region R12 constituting the first succeeding region. Further, the first succeeding region may be constituted by only one of the elastic material following region R11 and the sheet following region R12.
外裝頂部薄片、外裝背部薄片及外裝中心薄片係藉由不織布構成,若接著劑的基重過高,則有接著劑透過且露出之虞。但是,配置有外裝中心薄片100以覆蓋重疊區域R4,重疊區域R4的薄片層數比第1接著區域R1中的外裝中心薄片100重疊的部分以外的第1接著區域R1的薄片材層數更多。因此,重疊區域R4的接著劑之基重高,即使於接著劑從薄片材浸出之情形,仍可藉由作為覆蓋材的外裝中心薄片100予以保護。因而,能抑制 接著劑附著於穿用者的肌膚等而能防止肌膚問題。 The outer top sheet, the outer back sheet, and the outer center sheet are formed of a non-woven fabric. If the basis weight of the adhesive is too high, the adhesive is transmitted and exposed. However, the number of sheet layers of the first succeeding region R1 other than the portion in which the outer center sheet 100 is disposed so as to cover the overlap region R4 and the overlap region R4 is overlapped with the outer center sheet 100 in the first succeeding region R1 is disposed. More. Therefore, the basis weight of the adhesive in the overlap region R4 is high, and even if the adhesive is leached from the sheet, it can be protected by the exterior center sheet 100 as a cover material. Thus, it can be suppressed The adhesive adheres to the wearer's skin and the like to prevent skin problems.
又,亦可構成為在塗布有較多接著劑的薄片(例如,設置有重疊區域的薄片)之外側疊合另一片薄片。藉由在設置有重疊區域的薄片之外方向設置薄片,能使觸感柔軟。此外,本實施形態係設置外裝中心薄片以覆蓋重疊區域,但亦可配置其他薄片材覆蓋重疊區域。 Further, another sheet may be laminated on the outer side of the sheet coated with a large amount of the adhesive (for example, a sheet provided with an overlapping region). The touch is soft by providing a sheet in a direction other than the sheet provided with the overlapping area. Further, in the present embodiment, the exterior center sheet is provided to cover the overlapping area, but other sheets may be disposed to cover the overlapping area.
外裝體1B具有(第9圖參照):藉由腿圍彈性材使外裝體收縮的收縮區域R5;及在收縮區域的收縮方向與收縮區域R5相鄰配置,且外裝體未藉由腿圍彈性材收縮的非收縮區域R6。非收縮區域配置在比收縮區域更靠彈性構件被切斷的外裝體1B之端部側。 The outer casing 1B has (refer to FIG. 9) a contraction region R5 in which the outer casing is contracted by the leg-surrounding elastic material; and a contraction direction in the contraction region is disposed adjacent to the contraction region R5, and the outer casing is not used A non-contracted region R6 in which the leg elastic material contracts. The non-shrinkage region is disposed on the end side of the outer casing 1B whose elastic member is cut away from the contraction region.
收縮區域R5係指藉由經伸展固定的彈性構件之收縮,使得與彈性構件重疊的薄片之長度變成比收縮前短的狀態之區域。此處所說的收縮係指纖維長度比收縮前變短的狀態,也包含發現三維線圈狀的捲縮使外觀的纖維長度變短之狀態。此外,收縮區域係指實質上發現伸縮性之區域,即使是彈性構件存在的區域,亦不包含例如因為施以熱密封等使得剛性變高而實質上未發現伸縮性的區域。相對於此,非收縮區域R6係指寬度方向和長度方向皆不具有伸縮力之區域。非收縮區域的伸縮力為0(N/cm)。收縮區域R5的非收縮區域側之端部係收縮區域R5和非收縮區域R6之交界。 The contraction region R5 refers to a region in which the length of the sheet overlapping the elastic member becomes a state shorter than that before contraction by contraction of the elastic member fixed by stretching. The term "shrinkage" as used herein refers to a state in which the fiber length is shorter than before shrinkage, and also includes a state in which a three-dimensional coil-like crimp is found to shorten the fiber length of the appearance. Further, the contraction region refers to a region in which the stretchability is substantially found, and even in the region where the elastic member exists, the region in which the rigidity is increased due to heat sealing or the like, and substantially no stretchability is found. On the other hand, the non-shrinkage region R6 refers to a region where neither the width direction nor the longitudinal direction has a stretching force. The expansion and contraction force of the non-shrinkage region is 0 (N/cm). The end portion of the contraction region R5 on the non-shrinkage region side is a boundary between the contraction region R5 and the non-contraction region R6.
收縮區域R5的非收縮區域之交界,例如可根據外觀上的收縮狀態而判斷。具體而言,根據有無皺摺而 判斷,未形成皺摺的平坦狀態之區域為非收縮區域,皺摺產生的區域為收縮區域。皺摺的端部為收縮區域和非收縮區域之交界。 The boundary of the non-shrinkage region of the contraction region R5 can be determined, for example, according to the contraction state in appearance. Specifically, depending on whether there are wrinkles or not It is judged that the region in which the wrinkle is not formed is a non-contracted region, and the region in which the wrinkles are generated is a contracted region. The end of the wrinkle is the junction of the contracted area and the non-contracted area.
又,收縮區域R5和非收縮區域R6之交界,藉由以下2種方法中任一者皆能檢測。 Further, the boundary between the contraction region R5 and the non-contraction region R6 can be detected by any of the following two methods.
第1檢測方法係根據長度檢測收縮區域R5和非收縮區域R6之交界。首先,在認為是收縮區域之端部的部位做標記。在不施力下放置試樣之狀態,從做標記位置向非收縮區域側,以任意長度在另一端做標記。然後,測定已做標記的2點間之距離。以該距離作為自然長度之距離A。 The first detection method detects the boundary between the contraction region R5 and the non-contraction region R6 based on the length. First, mark the part considered to be the end of the contraction area. The state in which the sample is placed without applying force is marked at the other end from the mark position to the non-shrinkage region side at an arbitrary length. Then, the distance between the two points marked has been determined. This distance is taken as the distance A of the natural length.
接著,將已做標記的2點間以手拉伸使其伸展,測定已做標記的2點間之距離。以該距離作為伸展時的距離B。 Next, the two points that have been marked are stretched by hand to stretch, and the distance between the two points marked is measured. This distance is taken as the distance B at the time of stretching.
此時,於滿足B>A之關係時,判定經測定的2點間包含於收縮區域。 At this time, when the relationship of B>A is satisfied, it is determined that the two points measured are included in the contraction region.
因此,修正認為是收縮區域的端部之部位的做標記位置,在偏離非收縮區域側的位置做標記,再度測定。 Therefore, the mark position at the portion considered to be the end portion of the contraction region is corrected, and the position deviated from the non-shrinkage region side is marked and measured again.
另一方面,測定之結果,於滿足B=A之關係時,判定經測定的2點間包含於非收縮區域。 On the other hand, as a result of the measurement, when the relationship of B=A is satisfied, it is determined that the two points measured are included in the non-contracted region.
為了決定收縮區域R5和非收縮區域R6之交界,在收縮區域側做標記,再度試行測定。已做標記的2點間之距離係檢測自然狀態的距離A和伸展狀態的距離B 成為相同距離之點,以此點作為收縮區域和非收縮區域之交界。 In order to determine the boundary between the contraction region R5 and the non-contraction region R6, marking is performed on the side of the contraction region, and the measurement is again attempted. The distance between the two points marked is the distance A of the natural state and the distance B of the extended state. It becomes the point of the same distance, and this point is used as the boundary between the contracted area and the non-contracted area.
又,第2檢測方法係根據應力檢測收縮區域R5和非收縮區域R6之交界。 Further, the second detection method detects the boundary between the contraction region R5 and the non-contraction region R6 based on the stress.
1)準備作為測定對象的試樣,以包含外觀上認為是收縮區域和非收縮區域之交界的部位(皺摺的端部)之方式,以預定尺寸採取彈性構件及重疊於彈性構件之薄片構件。試樣的尺寸,例如寬度為10mm,長度為自然長度(伸展時長度)且在50mm做記號,採取100mm長度。 1) A sample to be measured is prepared, and an elastic member and a sheet member overlapping the elastic member are taken in a predetermined size so as to include a portion (an end portion of the wrinkle) which is considered to be a boundary between the contracted region and the non-contracted region. . The size of the sample, for example, the width is 10 mm, the length is the natural length (length when stretched) and the mark is made at 50 mm, taking a length of 100 mm.
2)將上述試樣在50mm做記號的部分設定成位於拉伸試驗機的夾具內,安裝成夾在夾具間。 2) The 50 mm mark portion of the above sample was set in a jig of a tensile tester and mounted so as to be sandwiched between the jigs.
3)求出50mm長度的95%、亦即夾具間到達47.5mm時的應力值。 3) Find the stress value of 95% of the 50 mm length, that is, when the clamp reaches 47.5 mm.
4)縮短試樣的做標記長度以使收縮區域側的長度縮短,對於該長度求出夾具間同様地到達95%時的應力值。 4) The length of the mark of the sample is shortened so that the length of the side of the contraction region is shortened, and the stress value when the clamp reaches 95% in the same direction is obtained for the length.
5)上述應力到達零時的收縮區域側的做標記位置,成為收縮區域和非收縮區域之交界。 5) The mark position on the side of the contraction region when the above stress reaches zero becomes the boundary between the contraction region and the non-contraction region.
此外,測定應力的試樣之寬度及長度,可根據製品狀態做適當變更。 Further, the width and length of the sample for measuring the stress can be appropriately changed depending on the state of the product.
由於收縮區域R5的非收縮區域側的端部(收縮區域和非收縮區域之交界)位於重疊區域,因此能從設置有重疊區域的部分使薄片材收縮,而能使意圖的區域收 縮。例如,於非連續地設置腿部皺摺之情形,能抑制非連續地配置的腿圍彈性材的端部之偏離。因此,已配置的腿圍彈性材有效地發揮作用,能實現在欲設置腿部皺摺的部位配置最小必要限度的彈性材。再者,由於也不會浪費夾入彈性構件的薄片,而能設置成本效益優異的皺摺。 Since the end portion of the contraction region R5 on the non-shrinkage region side (the boundary between the contraction region and the non-contraction region) is located in the overlap region, the sheet can be shrunk from the portion where the overlap region is provided, and the intended region can be collected. Shrink. For example, in the case where the leg wrinkles are provided discontinuously, the deviation of the end portions of the leg-surrounding elastic members which are discontinuously arranged can be suppressed. Therefore, the leg elastic material that has been disposed effectively functions, and an elastic material having a minimum necessary limit in the portion where the leg wrinkles are to be provided can be realized. Further, since the sheet sandwiched between the elastic members is not wasted, wrinkles excellent in cost efficiency can be provided.
接著,邊參照第10圖~第18圖邊說明變形例之拋棄式紙尿布。此外,以下實施形態中,有關與上述實施形態同様的構成係附加相同符號而省略說明。 Next, the disposable diaper of the modification will be described with reference to Figs. 10 to 18 . In the following embodiments, the same components as those of the above-described embodiments are denoted by the same reference numerals and will not be described.
第10圖係顯示變形例1的拋棄式紙尿布之圖。第11圖係沿著第10圖所示之X4-X’4線的外裝體之剖視圖。變形例1的拋棄式紙尿布不具備外裝中心薄片100,而藉由吸收性主體1A連結前側外裝頂部薄片及前側外裝背部薄片、後側外裝頂部薄片及後側外裝背部薄片。 Fig. 10 is a view showing the disposable diaper of Modification 1.

The auxiliary sheet 101 is disposed between the rear side outer top sheet and the rear side outer back sheet. The auxiliary sheet 101 is formed by an SMS nonwoven fabric having a basis weight of 13 g/m 2 , and the exterior top sheet of Modification 1 is formed by a spunbonded nonwoven fabric having a basis weight of 18 g/m 2 , and the exterior back sheet is made of a basis weight of 16 g. /m 2 spunbonded non-woven fabric.
如此地構成之拋棄式紙尿布之製造方法,係於輔助薄片101或外裝背部薄片,設置用以接合輔助薄片101和外裝背部薄片之輔助薄片接著區域R7。在輔助薄片接著區域R7,藉由狹縫式塗布機方式之接觸塗布以基重8g/m2塗布接著劑。然後,接合輔助薄片101和外裝背部薄片。 The manufacturing method of the disposable paper diaper thus constructed is based on the auxiliary sheet 101 or the outer back sheet, and an auxiliary sheet following region R7 for joining the auxiliary sheet 101 and the outer back sheet is provided. In the auxiliary sheet following region R7, an adhesive was applied at a basis weight of 8 g/m 2 by contact coating by a slit coater method. Then, the auxiliary sheet 101 and the exterior back sheet are joined.
接著,在配置接合有輔助薄片101和外裝背部薄片的複合薄片之腿圍彈性材側之面,設置第2接著區域R2。在第2接著區域R2藉由狹縫式塗布機方式之接觸塗布,以基重10g/m2塗布接著劑。在配置有複合薄片之腿圍彈性材側之面,設置彈性材接著區域R11後,將腿圍彈性材以伸展狀態配置。在彈性材接著區域R11藉由螺旋方式之非接觸塗布,以基重8g/m2塗布接著劑。 Next, the second succeeding region R2 is provided on the side of the leg-surrounding elastic material side of the composite sheet to which the auxiliary sheet 101 and the exterior back sheet are joined. In the second subsequent region R2, contact application was carried out by a slit coater method, and an adhesive was applied at a basis weight of 10 g/m 2 . After the elastic material following region R11 is provided on the side of the leg-surrounding elastic material side on which the composite sheet is disposed, the leg-surrounding elastic material is placed in an extended state. The adhesive was applied at a basis weight of 8 g/m 2 in a non-contact coating by a spiral method in the elastic material following region R11.
又,在外裝頂部薄片設置薄片接著區域R12用以接合外裝頂部薄片和複合薄片。在薄片接著區域R12藉由控制縫方式之非接觸塗布,以基重1.5g/m2塗布接著劑。將外裝頂部薄片和複合薄片重疊並加壓後,切斷從外裝頂部薄片及複合薄片伸出的腿圍彈性材,藉此即能製造外裝體。 Further, a sheet-following region R12 is provided on the exterior top sheet for joining the exterior top sheet and the composite sheet. The adhesive was applied at a basis weight of 1.5 g/m 2 in the sheet follow-up region R12 by non-contact coating by a controlled slit method. After the exterior top sheet and the composite sheet are overlapped and pressurized, the leg-surrounding elastic material extending from the exterior top sheet and the composite sheet is cut, whereby the exterior body can be manufactured.
再者,變形例1之拋棄式紙尿布係腿圍開口部位於比吸收性主體更靠寬度方向外側,因此亦可使吸收性主體1A貼合於外裝體1B後形成腿圍開口部。 Further, in the disposable diaper of the first modification, the leg-opening portion is located on the outer side in the width direction of the absorbent main body. Therefore, the absorbent main body 1A can be bonded to the outer casing 1B to form the leg-opening portion.
第12圖係構成變形例2之拋棄式紙尿布的外 裝體之剖視圖。變形例1之拋棄式紙尿布係將輔助薄片101設置於外裝頂部薄片和外裝背部薄片之間,變形例2之拋棄式紙尿布係將輔助薄片配置在比外裝頂部薄片更靠內方向。此外,輔助薄片101亦可配置在比外裝背部薄片更靠外方向。 Figure 12 is a view of the disposable diaper constituting the modification 2 A cross-sectional view of the body. In the disposable diaper of the first modification, the auxiliary sheet 101 is disposed between the exterior top sheet and the exterior back sheet, and the disposable diaper of the second modification arranges the auxiliary sheet in the inner direction of the outer sheet. . Further, the auxiliary sheet 101 may be disposed in an outer direction from the outer back sheet.
輔助薄片101係藉由基重16g/m2之紡黏不織布形成,外裝頂部薄片係藉由基重15g/m2之SMS不織布形成,外裝背部薄片係藉由基重16g/m2之紡黏不織布形成。 The auxiliary sheet 101 is formed by a spunbonded nonwoven fabric having a basis weight of 16 g/m 2 , and the exterior top sheet is formed by an SMS non-woven fabric having a basis weight of 15 g/m 2 , and the outer back sheet is made of a basis weight of 16 g/m 2 . Spunbonded non-woven fabric is formed.
如此地構成之拋棄式紙尿布之製造方法,係將第2接著區域R2設置於外裝頂部薄片。在第2接著區域R2藉由狹縫式塗布機方式之接觸塗布,以基重20g/m2且以條狀塗布接著劑。第2接著區域R2係以2mm寬度設置有5條,各第2接著區域R2之間相隔2mm。藉由如此地設置第2接著區域,能緩和薄片重疊成3層的重疊區域之硬度。 In the method of manufacturing a disposable diaper configured as described above, the second succeeding region R2 is provided on the exterior top sheet. In the second subsequent region R2, contact application was carried out by a slit coater method, and an adhesive was applied in a strip shape at a basis weight of 20 g/m 2 . The second succeeding region R2 is provided with five strips having a width of 2 mm, and each of the second succeeding regions R2 is spaced apart by 2 mm. By providing the second succeeding region in this manner, it is possible to alleviate the hardness of the overlapping region in which the sheets are stacked in three layers.
接著,在外裝頂部薄片設置彈性材接著區域R11後,將腿圍彈性材以伸展狀態配置。在彈性材接著區域R11藉由螺旋方式之非接觸塗布,以基重8g/m2塗布接著劑。 Next, after the elastic top material region R11 is provided on the exterior top sheet, the leg-surrounding elastic material is placed in an extended state. The adhesive was applied at a basis weight of 8 g/m 2 in a non-contact coating by a spiral method in the elastic material following region R11.
又,在外裝背部薄片設置薄片接著區域R12用以接合外裝頂部薄片和外裝頂部薄片。在薄片接著區域R12藉由控制縫方式之非接觸塗布,以基重1.5g/m2塗布接著劑。然後,接合外裝頂部薄片和外裝背部薄片。 Further, a sheet-following region R12 is provided on the exterior back sheet for joining the exterior top sheet and the exterior top sheet. The adhesive was applied at a basis weight of 1.5 g/m 2 in the sheet follow-up region R12 by non-contact coating by a controlled slit method. Then, the outer top sheet and the outer back sheet are joined.
而且,在輔助薄片101設置輔助薄片接著區域R7用以接合輔助薄片101和外裝頂部薄片。在輔助薄片接著區域R7藉由狹縫式塗布機方式之接觸塗布,以基重8g/m2塗布接著劑。然後,接合輔助薄片101和外裝頂部薄片。 Moreover, an auxiliary sheet subsequent region R7 is provided on the auxiliary sheet 101 for joining the auxiliary sheet 101 and the exterior top sheet. The adhesive was applied at a basis weight of 8 g/m 2 in the auxiliary sheet subsequent region R7 by contact coating by a slit coater method. Then, the auxiliary sheet 101 and the exterior top sheet are joined.
第13圖係變形例3之拋棄式紙尿布的展開俯視圖。相較於變形例1之拋棄式紙尿布,後腿圍彈性材不同。變形例3之後腿圍彈性材5R的前腹圍區域側的端部,不是配置在後側外裝頂部薄片的前端部及後側外裝背部薄片的前端部,而是配置在寬度方向中心側的吸收性主體的側部。 Fig. 13 is a developed plan view of the disposable diaper of Modification 3. Compared with the disposable diaper of Modification 1, the hind legs are different in elastic material. In the third modification, the end portion of the leg-surrounding elastic material 5R on the front abdominal region side is disposed not at the front end portion of the rear exterior sheet and the front end portion of the rear-side exterior sheet, but at the center side in the width direction. The side of the absorbent body.
這種配置後腿圍彈性材的方法,例如將左側的腿圍彈性材和右側的腿圍彈性材以連續狀態配置,在製品中心部切斷後腿圍彈性材。第13圖係示意顯示切斷部位C。在製品中心部被切斷的後腿圍彈性材5R朝寬度方向外側收縮,左右的後腿圍彈性材係分離配置。 In the method of arranging the rear leg elastic material, for example, the left leg elastic material and the right leg elastic material are disposed in a continuous state, and the rear leg elastic material is cut at the center of the product. Figure 13 is a schematic view showing the cut portion C. The hind leg surrounding elastic material 5R cut at the center of the product is contracted outward in the width direction, and the left and right rear leg surrounding elastic members are separated from each other.
事先在吸收性主體的兩側部設置第2接著區域R2,在配置腿圍彈性構件的區域設置第1接著區域R1,且以被覆第1接著區域和第2接著區域重疊的重疊區域R4的方式在外裝頂部薄片的內方向配置輔助薄片101。如此地,藉由設置第1接著區域R1、第2接著區域R2及輔助薄片101,使回切的彈性構件保持於重疊區域,而能在意圖的區域配置伸展狀態的彈性構件。 The second contiguous region R2 is provided on both sides of the absorbent body in advance, and the first contiguous region R1 is provided in the region where the leg-hole elastic member is disposed, and the overlapping region R4 in which the first contiguous region and the second contiguous region are overlapped is covered. The auxiliary sheet 101 is disposed in the inner direction of the exterior top sheet. In this manner, by providing the first succeeding region R1, the second succeeding region R2, and the auxiliary sheet 101, the back-cut elastic member is held in the overlapping region, and the elastic member in the extended state can be disposed in the intended region.
第14圖係變形例4之拋棄式紙尿布以第2圖 所示之X3-X’3線為基準之示意剖視圖。變形例4之拋棄式紙尿布對於實施形態之拋棄式紙尿布,係後腿圍彈性材5R的前端部51之位置不同。 Figure 14 is a disposable paper diaper of Modification 4, Figure 2 The X3-X'3 line shown is a schematic cross-sectional view of the reference. Disposable Paper Diaper of Modification 4 The disposable paper diaper of the embodiment has a different position of the front end portion 51 of the rear leg elastic material 5R.
變形例4之拋棄式紙尿布的後腿圍彈性材5R的前端部51並非配置在重疊區域R4,而是位於比重疊區域R4更靠前方。但是,後腿圍彈性材5R的前端部51未藉由接著劑確實地接合在後側外裝頂部薄片等,後腿圍彈性材5R係自前端部51起,在一定的區域為非伸展狀態。因此,後腿圍彈性材5R的收縮區域R5的非收縮區域R6側之端部,在比後腿圍彈性材5R的前端部51更靠後方,與重疊區域R4的前端部一致。 The front end portion 51 of the rear leg elastic member 5R of the disposable diaper of the fourth modification is not disposed in the overlap region R4 but in the front side of the overlap region R4. However, the front end portion 51 of the rear leg elastic member 5R is not reliably joined to the rear outer top sheet or the like by the adhesive, and the rear leg elastic member 5R is from the front end portion 51 and is in a non-stretched state in a certain region. . Therefore, the end portion of the contraction region R5 of the rear leg elastic material 5R on the non-contraction region R6 side is rearward of the front end portion 51 of the rear leg elastic member 5R, and coincides with the front end portion of the overlap region R4.
此外,變形例4之拋棄式紙尿布係收縮區域R5的非收縮區域R6側的端部與重疊區域R4的前端部一致,但不限於此構成。例如,亦可將收縮區域R5的非收縮區域R6側的端部配置於重疊區域R4內。又,可將後腿圍彈性材5R的前端部51配置在比重疊區域更靠外方向(第14圖所示之前方),且在與第2接著區域R2重疊的區域內,亦可配置在比重疊區域更靠外方向,且在與第2接著區域R2不重疊的區域內。 Further, the end portion of the disposable diaper-retracted region R5 of the fourth modification on the non-contracted region R6 side coincides with the front end portion of the overlapping region R4, but the configuration is not limited thereto. For example, the end portion of the contraction region R5 on the non-contraction region R6 side may be disposed in the overlap region R4. Moreover, the front end portion 51 of the rear leg elastic member 5R can be disposed in the outer direction (the front side as shown in FIG. 14) than the overlap region, and can be disposed in the region overlapping the second rear region R2. It is outside the overlapping area and is in a region that does not overlap the second subsequent region R2.
第15圖係變形例5之拋棄式紙尿布以第2圖所示之X3-X’3線為基準之示意剖視圖。變形例5之拋棄式紙尿布相對於實施形態之拋棄式紙尿布,係後腿圍彈性材5R的前端部51之位置、及後側外裝頂部薄片70R和後側外裝背部薄片80R之位置關係不同。 Fig. 15 is a schematic cross-sectional view showing the disposable diaper of Modification 5 based on the X3-X'3 line shown in Fig. 2. The disposable diaper of the fifth modification is a position of the front end portion 51 of the rear leg elastic material 5R and the position of the rear outer top sheet 70R and the rear outer surface sheet 80R with respect to the disposable diaper of the embodiment. The relationship is different.
變形例5之拋棄式紙尿布的後腿圍彈性材5R的前端部51係與第2接著區域R2的前後方向端部一致。但是,後腿圍彈性材5R的前端部51未藉由接著劑確實地接合於後側外裝頂部薄片等,後腿圍彈性材5R係自前端部51起,在一定的區域以非伸展狀態配置。因此,藉由後腿圍彈性材5R形成之收縮區域R5的非收縮區域R6側之端部,位於比後腿圍彈性材5R的前端部51更靠後方,且比重疊區域R4的前端部更靠後方。亦即,藉由後腿圍彈性材5R形成之收縮區域R5的非收縮區域R6側之端部位於重疊區域R4內。 The front end portion 51 of the rear leg elastic member 5R of the disposable diaper of the fifth modification coincides with the front end portion of the second succeeding region R2. However, the front end portion 51 of the rear leg elastic member 5R is not reliably joined to the rear outer top sheet or the like by the adhesive, and the rear leg elastic member 5R is from the front end portion 51 and is in a non-stretched state in a certain region. Configuration. Therefore, the end portion of the contraction region R5 formed by the rear leg elastic member 5R on the non-contraction region R6 side is located further rearward than the front end portion 51 of the rear leg elastic member 5R, and is more than the front end portion of the overlap region R4. Behind the back. That is, the end portion of the contraction region R5 formed by the rear leg elastic material 5R on the non-contraction region R6 side is located in the overlap region R4.
又,變形例5之後側外裝背部薄片80R的前端部,位於比後側外裝頂部薄片70R的前端部更靠前方。後側外裝背部薄片80R的前端部,位於比後側外裝頂部薄片70R的前端部更靠前後方向外側(第15圖所示之前側),因此在後側外裝頂部薄片70R的前端部附近所塗布的第2接著區域R2的前端部,能防止後側外裝背部薄片80R朝前後方向外側伸出。例如,製造時,即使有後側外裝頂部薄片70R的位置偏移、後側外裝背部薄片80R的位置偏移、第2接著區域的位置偏移之情形,仍可藉由後側外裝背部薄片80R覆蓋第2接著區域,而能防止接著劑露出。 Moreover, in the modification 5, the front end portion of the rear exterior back sheet 80R is located further forward than the front end portion of the rear exterior top sheet 70R. The front end portion of the rear exterior back sheet 80R is located on the outer side in the front-rear direction (the front side shown in FIG. 15) than the front end portion of the rear exterior top sheet 70R, so that the front end portion of the top sheet 70R is attached to the rear side. The front end portion of the second succeeding region R2 applied in the vicinity can prevent the rear exterior back sheet 80R from protruding outward in the front-rear direction. For example, at the time of manufacture, even if the position of the rear exterior top sheet 70R is shifted, the position of the rear exterior back sheet 80R is shifted, and the position of the second succeeding region is shifted, the rear side exterior can be used. The back sheet 80R covers the second succeeding region to prevent the adhesive from being exposed.
此外,就防止後側外裝頂部薄片70R和後側外裝背部薄片80R之間的接著劑露出之觀點而言,後側外裝頂部薄片70R和後側外裝背部薄片80R當中,將位於 外方向OUT的薄片材之端部配置成比位於內方向IN的薄片材之端部更延伸出去為期望。但是,作為變形例,亦可將位於內方向IN的薄片材之端部配置成比位於外方向OUT的薄片材之端部更延伸出去。 Further, from the viewpoint of preventing the adhesion between the rear side outer top sheet 70R and the rear side outer back sheet 80R, the rear side outer top sheet 70R and the rear side outer back sheet 80R will be located. It is desirable that the end portion of the sheet material in the outer direction OUT is disposed to extend more than the end portion of the sheet material located in the inner direction IN. However, as a modification, the end portion of the sheet material located in the inner direction IN may be disposed to extend beyond the end portion of the sheet material located in the outer direction OUT.
又,第2接著區域R2的基重比第1接著區域R1高,接著劑容易溢出。因此,就防止第2接著區域R2的接著劑溢出之觀點而言,將配置塗布在薄片材的端部側之接著劑(構成第2接著區域R2之接著劑)的薄片材,配置在比其他薄片材更靠前後方向內側為期望。 Further, the basis weight of the second succeeding region R2 is higher than that of the first succeeding region R1, and the adhesive agent easily overflows. Therefore, the sheet material which is disposed on the end side of the sheet material (the adhesive constituting the second succeeding region R2) is disposed in comparison with the other from the viewpoint of preventing the adhesive from overflowing in the second succeeding region R2. It is desirable that the sheet material is further inward in the front-rear direction.
又,後側外裝頂部薄片70R的前端部和後側外裝背部薄片80R的前端部之距離L1以0~15mm為期望。例如,若後側外裝頂部薄片70R的前端部和後側外裝背部薄片80R的前端部之距離L1過長,則後側外裝頂部薄片70R和後側外裝背部薄片80R積層的區域會變短,而有腿圍彈性材露出之虞。 Further, the distance L1 between the front end portion of the rear exterior top sheet 70R and the front end portion of the rear exterior back sheet 80R is preferably 0 to 15 mm. For example, if the distance L1 between the front end portion of the rear exterior top sheet 70R and the front end portion of the rear outer cover back sheet 80R is too long, the area where the rear side outer top sheet 70R and the rear side outer back sheet 80R are laminated Shortened, and the elastic material with legs is exposed.
如實施形態,不僅沿著構成外裝體的薄片材之端部切斷彈性構件之構成,亦可適用於在外裝體的端部以外的部分切斷彈性構件之形態。 In the embodiment, the configuration of the elastic member is not only cut along the end portion of the sheet material constituting the exterior body, but also applied to the portion other than the end portion of the exterior body.
第16圖~第18圖係顯示變形例6之作為吸收性物品的拋棄式紙尿布之圖。第16圖係變形例6之拋棄式紙尿布的展開俯視圖。變形例6之拋棄式紙尿布具備:吸收性主體1A、及配置在比吸收性主體1A更靠外方向之外裝體1B。拋棄式紙尿布具備:位於穿用者的胯間部之***區域S3、配置在***區域的前方之前腹圍區域 S1、以及配置在***區域的後方之後腹圍區域S2。吸收體40具有一對彎曲部,該一對彎曲部位於比吸收體40的寬度方向中心更靠寬度方向兩外側,且形成為能使吸收體朝外方向彎曲成凸狀。 Fig. 16 to Fig. 18 are views showing a disposable paper diaper as an absorbent article of Modification 6. Fig. 16 is a developed plan view of the disposable diaper of Modification 6. The disposable diaper of the sixth modification includes the absorbent main body 1A and the package 1B disposed outside the absorbent main body 1A. The disposable diaper has a crotch region S3 located at the crotch portion of the wearer and a crotch region disposed in front of the crotch region S1, and the abdominal area S2 after being disposed behind the crotch region. The absorber 40 has a pair of curved portions which are located on the outer side in the width direction from the center in the width direction of the absorber 40, and are formed so that the absorber can be curved in a convex shape in the outward direction.
彎曲部係沿著長邊方向形成的壓榨部47。壓榨部係使吸收體在厚度方向壓縮而形成。此外,本實施形態的彎曲部係藉由壓榨部構成,但亦可藉由形成在吸收體的縫隙(例如,側縫隙46)構成。又,吸收體40具有中央吸收部,該中央吸收部配置在一對壓榨部47間,且不具有彎曲部。中央吸收部係吸收體40的壓榨部47之間的區域,且係未形成有構成彎曲部的壓榨部及縫隙之區域。 The bent portion is a press portion 47 formed along the longitudinal direction. The press section is formed by compressing the absorber in the thickness direction. Further, although the curved portion of the present embodiment is constituted by a press portion, it may be constituted by a slit (for example, a side slit 46) formed in the absorber. Further, the absorber 40 has a central absorbing portion that is disposed between the pair of press portions 47 and does not have a bent portion. The central absorbing portion is a region between the press portions 47 of the absorber 40, and a region where the press portion and the slit constituting the bent portion are not formed.
一對彎曲部係於吸收體朝外方向變形時,作為使吸收體變形成覆蓋穿用者的臀部之變形基點,因此位於比穿用者的臀部之窪陷位置更靠寬度方向外側為期望。又,一對彎曲部間之距離(中央吸收部的寬度方向之長度),可因應後述糞便的收容空間等而適當設定,本實施形態中為50mm。 When the pair of curved portions are deformed in the outward direction, the absorbent body is deformed to cover the deformed base of the buttocks of the wearer. Therefore, it is desirable to be located outward in the width direction from the collapsed position of the buttocks of the wearer. In addition, the distance between the pair of curved portions (the length of the central absorbent portion in the width direction) can be appropriately set in accordance with the storage space of the stool described later, and is 50 mm in the present embodiment.
在外裝體1B配置有作為複數個彈性構件的後腿圍彈性材5R。後腿圍彈性材5R具有:直線狀之直線部52,係朝寬度方向延伸;及曲線狀之曲線部53,位於比直線部52更靠寬度方向兩外側,且從寬度方向內側朝向寬度方向外側,從作為前後方向內側之前側朝作為前後方向外側之後側延伸。直線部52係沿著腹圍彈性材配置。曲線部係沿著腿圍開口部9配置。 A rear leg elastic material 5R as a plurality of elastic members is disposed in the exterior body 1B. The rear leg elastic material 5R has a linear straight portion 52 extending in the width direction, and a curved curved portion 53 located outward in the width direction from the straight portion 52 and outward in the width direction from the inner side in the width direction. It extends from the front side as the inner side in the front-rear direction toward the rear side as the outer side in the front-rear direction. The straight portion 52 is disposed along the abdominal elastic material. The curved portion is disposed along the leg-opening portion 9.
後腿圍彈性材5R的直線部52係與吸收體的壓榨部47重疊。直線部52和壓榨部47係於厚度方向重疊。此外,所謂直線部52和壓榨部47重疊的狀態,不僅是以直線部52和壓榨部47接觸的狀態重疊之狀態,如本實施形態,亦包含透過後側外裝頂部薄片70R等其他構件重疊的狀態之概念。 The straight portion 52 of the hind leg surrounding elastic material 5R overlaps with the press portion 47 of the absorber. The straight portion 52 and the press portion 47 are overlapped in the thickness direction. In addition, the state in which the linear portion 52 and the press portion 47 are overlapped is not only in a state in which the linear portion 52 and the press portion 47 are in contact with each other, but in the present embodiment, the other components such as the rear-side exterior top sheet 70R are also overlapped. The concept of the state.
後腿圍彈性材5R的曲線部53係配置在比吸收體40更靠寬度方向外側。後腿圍彈性材5R的曲線部53和吸收體在厚度方向配置成不重疊。 The curved portion 53 of the hind leg surrounding elastic material 5R is disposed on the outer side in the width direction of the absorber 40. The curved portion 53 of the hind leg surrounding elastic material 5R and the absorber are disposed so as not to overlap each other in the thickness direction.
後腿圍彈性材5R的曲線部53之伸展率,比後腿圍彈性材5R的直線部52之伸展率更高。此處所謂的伸展率係使拋棄式紙尿布伸展之伸展狀態下的伸展率S。伸展率例如可藉由以下方法測定。 The stretch ratio of the curved portion 53 of the hind leg elastic member 5R is higher than the stretch ratio of the straight portion 52 of the rear leg elastic member 5R. The stretching ratio referred to herein is an elongation ratio S in a stretched state in which the disposable diaper is stretched. The elongation can be measured, for example, by the following method.
以使彈性構件伸展100%的狀態固定製品,測定直線部(內側寬度方向兩端部間)及曲線部(從卡止的內側到前述內側寬度方向兩端部)之尺寸(此尺寸為I)。在前述記載的直線部及曲線部之端部加上記號後,切斷彈性構件部分。完全去除熱熔等附著物後,於使非伸展狀態的彈性構件筆直地放置之狀態,以尺測定尺寸(此尺寸為II)。I/II之計算值為伸展率。 The product is fixed in a state in which the elastic member is stretched by 100%, and the dimensions of the straight portion (between both end portions in the inner width direction) and the curved portion (from the inner side of the inner side to the inner side in the width direction) are measured (this size is I). . After the mark is added to the end portions of the straight portion and the curved portion described above, the elastic member portion is cut. After completely removing the adherend such as hot melt, the elastic member in the non-stretched state is placed in a straight state, and the size is measured by a ruler (this size is II). The calculated value of I/II is the stretch rate.
具體而言,直線部的伸展率為1.2~1.6倍,曲線部的伸展率為2.1~2.5倍。 Specifically, the elongation of the straight portion is 1.2 to 1.6 times, and the elongation of the curved portion is 2.1 to 2.5 times.
如此地構成之拋棄式紙尿布,在穿用者穿用之狀態下,藉由利用穿用者的腿夾住吸收體,透過吸收體 40的一對壓榨部47使吸收體40朝外方向變形。由於吸收體40以壓榨部47為起點而變形,因此將壓榨部47間的吸收體配置成與穿用者的胯間部相對向。此時,吸收體40的壓榨部47間為未形成有彎曲部的中央吸收部,因此壓榨部47間的中央吸收部不易成為變形基點。因此,在穿用者的胯間部之下方,與胯間部分離配置有平面狀態的吸收體,可在穿用者的下方形成糞便等的收容空間。 The disposable diaper thus constructed is passed through the absorbent body by the wearer's leg while the wearer is wearing it. A pair of press portions 47 of 40 deforms the absorber 40 in the outward direction. Since the absorber 40 is deformed from the press portion 47 as a starting point, the absorber between the press portions 47 is disposed to face the inter-turn portion of the wearer. At this time, since the press portion 47 of the absorber 40 is a central absorbent portion in which the bent portion is not formed, the central absorbent portion between the press portions 47 is less likely to be a deformation base point. Therefore, a flat state absorbent body is disposed below the crotch portion of the wearer, and a accommodating space such as feces can be formed below the wearer.
又,在一對壓榨部重疊有直線部,因此藉由直線部的收縮使一對彎曲部間的距離變短,而使得與穿用者的胯間部相對向配置之空間的寬度方向長度變短。吸收體的寬度從與胯間部相對向的區域朝向其前後方向擴展。因此,吸收體形成碗形狀,該碗形狀係從***朝向前後方向外側、從寬度方向內側朝寬度方向外側擴展。可沿著臀部等身體的弧度配置吸收體。 Further, since the straight portions are overlapped in the pair of press portions, the distance between the pair of bent portions is shortened by the contraction of the straight portions, and the length in the width direction of the space disposed opposite to the wearer's crotch portion is changed. short. The width of the absorber expands from the region facing the crotch portion toward the front-rear direction. Therefore, the absorber has a bowl shape which expands from the crotch toward the outer side in the front-rear direction and from the inner side in the width direction toward the outer side in the width direction. The absorber can be arranged along the curvature of the body such as the buttocks.
再者,由於曲線部的伸展率比直線部高,因此比吸收體更位於寬度方向外側的外裝體及吸收性主體變得容易收縮。藉由比吸收體更靠寬度方向外側的區域收縮,使吸收體容易拉起,而能將吸收體沿著穿用者的身體配置。 In addition, since the elongation of the curved portion is higher than that of the straight portion, the outer casing and the absorbent main body which are located outside the absorbent body in the width direction are more likely to shrink. By shrinking the outer side of the absorbent body in the width direction, the absorbent body can be easily pulled up, and the absorbent body can be disposed along the wearer's body.
例如,若與吸收體重疊配置的彈性構件(本實施形態中為後腿圍彈性材5R)之伸展率較高,則因為腿圍彈性材的收縮,有時會有吸收體以非意圖之狀態變形的情形。若吸收體形成接觸於穿用者的部分即吸收體不意圖之凹凸,則吸收體和身體變成容易以點接觸,吸收體接 觸的部分和不接觸的部分之觸感產生差異,而產生不舒服感。又,若不意圖之凹凸形成於吸收體的表面,則沿著身體配置的部分不會形成為一定,收容糞便的空間消失,有時容易產生糞便漏出的情形。 For example, when the elastic member (the rear leg elastic material 5R in the present embodiment) which is disposed to overlap the absorbent body has a high stretch ratio, the absorbent body may have an unintended state due to shrinkage of the leg elastic material. The situation of deformation. If the absorbent body forms a portion that is in contact with the wearer, that is, the unintentional unevenness of the absorbent body, the absorbent body and the body become easy to be in point contact, and the absorbent body is connected. The tactile sensation of the touched portion and the non-contacted portion is different, resulting in an uncomfortable feeling. Further, if the unintended irregularities are formed on the surface of the absorbent body, the portion disposed along the body is not formed to be constant, and the space for storing the feces disappears, and the feces may easily leak.
又,藉由在吸收體形成壓榨部等彎曲部,能在意圖的位置使吸收體變形。但是,於吸收體未緊貼於身體之情形,當穿用者進行走動等動作時,吸收體和身體之間更加產生間隙,吸收體接觸於腿部而變成容易產生不舒服感。再者,於吸收體未緊貼於身體之情形,若於讓穿用者長時間穿著之狀態,則有拋棄式紙尿布脫落、間隙產生造成容易產生漏出。 Further, by forming a bent portion such as a press portion in the absorber, the absorber can be deformed at an intended position. However, when the absorbent body is not in close contact with the body, when the wearer performs an action such as walking, a gap is further generated between the absorbent body and the body, and the absorbent body comes into contact with the leg portion to become uncomfortable. Further, in the case where the absorbent body is not in close contact with the body, if the wearer wears the hair for a long period of time, the disposable disposable diaper falls off and the gap is generated to cause leakage.
對於這種問題,根據變形例6之吸收性物品,係透過作為彎曲部之壓榨部47使吸收體變形成意圖的狀態,能在穿用者的下方形成收容糞便之空間。再者,由於與吸收體的壓榨部重疊的後腿圍彈性材5R之伸展率較低,因此能抑制在吸收體形成不意圖的凹凸,讓吸收體沿著穿用者的身體配置。 According to the absorbent article of the sixth modification, the absorbent article is formed into a desired state by the press portion 47 as the curved portion, and a space for storing the feces can be formed below the wearer. Further, since the stretch ratio of the hind leg-surrounding elastic material 5R which overlaps with the press portion of the absorbent body is low, it is possible to suppress the formation of unintentional irregularities in the absorbent body and to arrange the absorbent body along the wearer's body.
接著,根據第17圖及第18圖說明變形例6之拋棄式紙尿布穿著時的變形態様。第17圖係顯示變形例6之拋棄式紙尿布的伸展狀態,(a)為第16圖所示之X5-X’5線的剖視圖,(b)為第16圖所示之X6-X’6線的剖視圖。第18圖係顯示變形例6之拋棄式紙尿布的自然狀態,(a)為第16圖所示之X5-X’5線的剖視圖,(b)為第16圖所示之X6-X’6線的剖視圖。 Next, a modification of the disposable diaper of the sixth modification when worn will be described based on Figs. 17 and 18 . Fig. 17 is a view showing the stretched state of the disposable diaper of Modification 6, wherein (a) is a cross-sectional view taken along the line X5-X'5 shown in Fig. 16, and (b) is X6-X' shown in Fig. 16. 6-line cross-sectional view. Fig. 18 is a view showing the natural state of the disposable diaper of Modification 6, wherein (a) is a cross-sectional view taken along the line X5-X'5 shown in Fig. 16, and (b) is X6-X' shown in Fig. 16. 6-line cross-sectional view.
此外,所謂伸展狀態,係構成拋棄式紙尿布的表面薄片10和外裝頂部薄片等的皺紋無法以目視辨視之狀態為止,使腿圍彈性材和腰圍彈性材伸展之狀態。又,所謂自然狀態,係將拋棄式紙尿布在20℃±2℃、相對濕度60%±5%RH之雰圍下放置24小時之狀態。 In addition, the stretched state is a state in which the wrinkles such as the surface sheet 10 and the exterior top sheet of the disposable diaper are not visually recognized, and the leg-surrounding elastic material and the waist elastic material are stretched. Further, in the natural state, the disposable diaper was placed in an atmosphere of 20 ° C ± 2 ° C and a relative humidity of 60% ± 5% RH for 24 hours.
於使拋棄式紙尿布伸展之伸展狀態,拋棄式紙尿布的後腿圍彈性材5R等彈性構件伸展,外裝體1B和吸收體40等未藉由彈性構件收縮。因此,X5-X’5線的剖視圖中的壓榨部47間之距離D1與X6-X’6線的剖視圖中的壓榨部47間之距離D2為相同長度。 In the stretched state in which the disposable diaper is stretched, the elastic member such as the rear leg elastic material 5R of the disposable diaper is stretched, and the exterior body 1B, the absorbent body 40, and the like are not shrunk by the elastic member. Therefore, the distance D1 between the press portions 47 in the cross-sectional view of the X5-X'5 line and the distance D2 between the press portions 47 in the cross-sectional view of the X6-X'6 line are the same length.
另一方面,於拋棄式紙尿布的自然狀態,拋棄式紙尿布藉由後腿圍彈性材5R等彈性構件而收縮。穿用時,拋棄式紙尿布比自然狀態更接近於伸展狀態。吸收體40藉由後腿圍彈性材而收縮,X5-X’5線的剖視圖中的壓榨部間之距離D1比X6-X’6線的剖視圖中的壓榨部47間之距離D2更短。此時,吸收體40於以壓榨部47為起點變形後之狀態,朝寬度方向收縮,因此吸收體沿著穿用者的臀部之弧度變形成曲線狀。再者,比吸收體更位於寬度方向外側的腿圍彈性材5R的曲線部53的伸展率,比與吸收體重疊的腿圍彈性材5R的直線部52之伸展率更高,因此在比吸收體40更靠寬度方向外側,拋棄式紙尿布更為收縮。因此,比吸收體更位於寬度方向外側的外裝體緊貼於穿用者的身體,以覆蓋穿用者的臀部之方式穿著拋棄式紙尿布。 On the other hand, in the natural state of the disposable diaper, the disposable diaper is shrunk by an elastic member such as the rear leg elastic material 5R. When worn, the disposable diaper is closer to the stretch than the natural state. The absorbent body 40 is contracted by the hind leg surrounding elastic material, and the distance D1 between the press portions in the cross-sectional view of the X5-X'5 line is shorter than the distance D2 between the press portions 47 in the cross-sectional view of the X6-X'6 line. At this time, the absorber 40 is contracted in the width direction in a state where the press portion 47 is deformed as a starting point. Therefore, the absorber is curved along the curvature of the wearer's buttocks. Further, the stretch ratio of the curved portion 53 of the leg-surrounding elastic material 5R which is located outside the widthwise direction of the absorbent body is higher than the stretch ratio of the straight portion 52 of the leg-surrounding elastic material 5R which overlaps with the absorbent body, and therefore is absorbed in specific absorption. The body 40 is further outward in the width direction, and the disposable paper diaper is more contracted. Therefore, the outer body which is located outside the width direction of the absorbent body is in close contact with the wearer's body, and the disposable disposable diaper is worn so as to cover the buttocks of the wearer.
又,與穿用者的身體接觸之吸收體由於與伸展率較低的直線部重疊,因此不易變形。又,比吸收體更靠寬度方向外側係配置有伸展率較高的曲線部,因此比配置有吸收體的區域更容易收縮。曲線部係朝向後方且朝向寬度方向外側配置,因此於穿用狀態以使腿圍的後部朝後側拉起的方式發揮作用。因此,於穿用狀態,在拋棄式紙尿布,將吸收體朝斜上方拉起的力作用且吸收體緊貼於身體。藉由比吸收體更靠寬度方向外側的區域拉起拋棄式紙尿布全體,而沿著穿用者的身體配置吸收體,歩行時吸收體不易變形,能防止吸收體位於兩足間造成的不舒服感和吸收體的扭曲。 Further, since the absorbent body that is in contact with the wearer's body overlaps with the straight portion having a low stretch ratio, it is less likely to be deformed. Further, since the curved portion having a high stretch ratio is disposed on the outer side in the width direction from the absorber, it is easier to shrink than the region in which the absorber is disposed. Since the curved portion is disposed rearward and outward in the width direction, the wearing portion functions to pull the rear portion of the leg circumference toward the rear side in the wearing state. Therefore, in the wearing state, in the disposable diaper, the force that pulls the absorbent body upward obliquely acts and the absorbent body is in close contact with the body. By absorbing the entire disposable diaper from the outer side of the absorbent body in the width direction, the absorbent body is disposed along the wearer's body, and the absorbent body is not easily deformed during the squatting, thereby preventing the absorbent body from being uncomfortable between the two feet. Distortion of the sense and absorption body.
又,由於藉由腿圍彈性材5R拉起拋棄式紙尿布全體的力作用,因此能防止吸收體的寬度方向的位置偏移,且抑制吸收體的寬度方向端部伸入腿根。 In addition, since the force of the entire disposable disposable diaper is pulled up by the leg-surrounding elastic material 5R, the positional deviation of the absorbent body in the width direction can be prevented, and the end portion in the width direction of the absorbent body can be prevented from protruding into the leg root.
此外,若腿圍彈性材的彈性力過強,則對穿用者的刺激強,會有肌膚粗糙或產紅斑之虞。另一方面,若腿圍彈性材的彈性力過弱,則上述拉起力弱,變得不易使用或變得不易緊貼於身體,因此使用470dtex~940dtex為佳,腿圍彈性材的條數以2~4條為佳。 In addition, if the elastic force of the leg-surrounding elastic material is too strong, the stimulation to the wearer is strong, and there is a rough skin or erythema. On the other hand, if the elastic force of the leg-surrounding elastic material is too weak, the pulling-up force is weak, and it becomes difficult to use or becomes hard to be in close contact with the body. Therefore, it is preferable to use 470 dtex to 940 dtex, and the number of the leg-surrounding elastic members is good. It is better to use 2~4.
再者,直線部52由於在比吸收體的前後方向中心更靠後方與吸收體重疊,因此能使位於穿用者臀部的區域之吸收體變形成碗狀。因此,能沿著臀部弧度配置吸收體。 Further, since the straight portion 52 overlaps the absorber at the rear side of the center in the front-rear direction of the absorber, the absorber in the region of the wearer's buttocks can be formed into a bowl shape. Therefore, the absorber can be arranged along the buttocks.
吸收體具有傾斜區域48,該傾斜區域48係吸 收體的寬度方向之長度從吸收體的前後方向中心部朝向前後方向外側變長。後腿圍彈性材5R的直線部52係與吸收體的傾斜區域48重疊。傾斜區域係吸收體的寬度方向外側端部當中,吸收體的寬度方向之長度朝向前後方向外側(前側及後側)變長的區域。第16圖中,將傾斜區域以一點鏈線圍繞顯示。 The absorbent body has a sloped region 48 that is sucked The length in the width direction of the body is lengthened from the center portion in the front-rear direction of the absorber toward the outer side in the front-rear direction. The straight portion 52 of the rear leg elastic member 5R overlaps with the inclined region 48 of the absorber. The inclined region is a region in which the length in the width direction of the absorber is elongated toward the outer side (front side and rear side) in the front-rear direction among the outer end portions in the width direction of the absorber. In Fig. 16, the inclined area is displayed with a little chain line.
吸收體係由以下區域構成:位於吸收體的長邊方向中心之最狹窄區域、位於吸收體的長邊方向兩端部之最寬廣區域、以及傾斜區域。臀部側的傾斜區域位於最狹窄區域及最寬廣區域之間。仰睡或側睡時的側漏多半是尿從傾斜區域流出者。再者,若傾斜區域產生皺紋或翻捲,則吸收體變成不沿著身體的形狀,更容易產生側漏。但是,由於後腿圍彈性材5R的直線部52與吸收體的傾斜區域48重疊,因此藉由拉伸後腿圍彈性材5R的直線部52,即能消除吸收體的傾斜區域之皺紋。特別是在並非讓穿用者自己穿著,而是讓看護穿著時,拉伸後腿圍彈性材5R的直線部52,即能容易地消除吸收體的皺紋或翻捲。藉由減少吸收體的皺紋或翻捲,能減少體液漏出。 The absorption system is composed of a narrowest region located at the center in the longitudinal direction of the absorbent body, a widest region located at both end portions in the longitudinal direction of the absorbent body, and an inclined region. The sloped area on the hip side is located between the narrowest area and the widest area. Most of the side leakage when sleeping or sleeping on the side is the outflow of urine from the inclined area. Further, if the inclined region is wrinkled or rolled, the absorbent body becomes a shape that does not follow the body, and side leakage is more likely to occur. However, since the straight portion 52 of the rear leg elastic member 5R overlaps with the inclined portion 48 of the absorbent body, the wrinkles of the inclined region of the absorbent body can be eliminated by stretching the straight portion 52 of the rear leg elastic member 5R. In particular, when the wearer does not wear the wearer himself, the straight portion 52 of the leg elastic material 5R is stretched, that is, the wrinkles or the curl of the absorbent body can be easily eliminated. By reducing wrinkles or curling of the absorbent body, leakage of body fluids can be reduced.
此外,變形例6的拋棄式紙尿布之作為彈性構件的後腿圍彈性材5R具有直線部及曲線部,且橫跨彎曲部配置,但亦可構成為作為彈性構件的前腿圍彈性材5F具有直線部及曲線部,且橫跨彎曲部配置,使穿用者的前側所配置之部分變形成碗狀。 Further, the rear leg elastic material 5R as the elastic member of the disposable diaper of the sixth modification has a straight portion and a curved portion and is disposed across the curved portion, but may be configured as a front leg elastic material 5F as an elastic member. The linear portion and the curved portion are disposed so as to be disposed across the curved portion, and the portion disposed on the front side of the wearer is formed into a bowl shape.
接著,根據第19圖說明變形例7之作為吸收 性物品的拋棄式紙尿布。變形例7之拋棄式紙尿布係壓榨部47對長邊方向傾斜。一對壓榨部47間的距離為,比壓榨部的前後方向內側(前側)更靠壓榨部的前後方向外側(後側)者較長。如此地,由於壓榨部47為朝向前後方向外側擴展的形狀,因此吸收體藉由腿圍彈性材5R變形時,能使吸收體前側的壓榨部間之距離比吸收體後側的壓榨部47間之距離短,更能使拋棄式紙尿布變形成從***區域朝向後腹圍區域擴展的碗狀。 Next, the modification 7 will be described as an absorption according to FIG. Disposable disposable diapers for sexual goods. The disposable diaper press portion 47 of the seventh modification is inclined in the longitudinal direction. The distance between the pair of press portions 47 is longer than the inner side (front side) of the press portion in the front-rear direction (the rear side) of the press portion. In this manner, since the press portion 47 has a shape that expands outward in the front-rear direction, when the absorber is deformed by the leg-surrounding elastic material 5R, the distance between the press portions on the front side of the absorber can be made larger than the distance between the press portions 47 on the rear side of the absorber. The short distance allows the disposable diaper to be deformed into a bowl shape extending from the underarm area toward the rear abdominal area.
又,變形例6及變形例7之吸收體係寬度方向的長度從前後方向中心朝向前後方向外側變長的砂漏鐘形狀,但吸收體的形狀不限定於此。例如,吸收體的寬度方向之長度也可以是一定。 In addition, in the modified example 6 and the modified example 7, the length in the width direction of the absorption system is elongated from the center in the front-rear direction toward the outer side in the front-rear direction, but the shape of the absorber is not limited thereto. For example, the length of the absorbent body in the width direction may be constant.
變形例6及變形例7之吸收體的彎曲部係藉由壓榨部構成,但亦可藉由縫隙構成彎曲部。例如,於吸收體40的厚度較薄之情形,藉由在吸收體形成壓榨部47,形成有壓榨部47的區域和周圍的區域之間產生剛性差,而能以壓榨部為基點使吸收體變形。又,於吸收體40的厚度較厚之情形,壓榨部的深度必須形成較深。 The curved portions of the absorbent body according to the sixth modification and the seventh modification are constituted by the press portion, but the curved portion may be formed by the slit. For example, in the case where the thickness of the absorber 40 is thin, a difference in rigidity is generated between the region where the press portion 47 is formed and the surrounding region by forming the press portion 47 in the absorber, and the absorber can be made based on the press portion. Deformation. Further, in the case where the thickness of the absorber 40 is thick, the depth of the press section must be formed deep.
另一方面,於使用縫隙作為彎曲部之情形,能以縫隙為基點使吸收體變形。縫隙比壓榨部更不因吸收體的厚度即能設置。但是,在形成有縫隙的部分未配置作為吸收性材料之紙漿等,因此會有尿沿著縫隙流動之情形。特別是於側睡、仰睡之狀態,若是尿從排尿點流過縫隙,則尿流動的方向成為重力方向,因此在縫隙上流速變 快,容易產生漏出。因此,不是根據穿用者的姿勢,而是根據不易漏出之觀點,形成壓榨部比縫隙為佳。 On the other hand, in the case where a slit is used as the bent portion, the absorber can be deformed with the slit as a base point. The slit can be set more than the press portion due to the thickness of the absorber. However, since pulp or the like as an absorbent material is not disposed in the portion where the slit is formed, there is a case where urine flows along the slit. Especially in the state of sleeping on the side and sleeping on the side, if the urine flows through the gap from the urination point, the direction of the urine flow becomes the direction of gravity, so the flow velocity on the gap becomes Fast, easy to leak. Therefore, it is preferable to form the press section rather than the slit depending on the posture of the wearer but from the viewpoint of not easily leaking.
