[0008] Patent Document 2: EP3381424A1 Summary of the Invention

[0009] The present invention relates to an absorbent article having a longitudinal direction corresponding to the front-back direction of the wearer and a transverse direction orthogonal to the longitudinal direction, and having a crotch portion disposed at the crotch of the wearer and an abdominal portion and a dorsal portion extending front-back along the crotch portion. The absorbent article includes an absorbent body and a pair of leak-proof flanges. The absorbent body contains a liquid-retaining absorbent core, and the leak-proof flanges are disposed along the two sides of the absorbent body along the longitudinal direction.

[0010] The leak-proof folding edge preferably has a strip-shaped skin-contact portion and a raised portion. The skin-contact portion has a skin-contact surface that comes into contact with the wearer's skin, and the raised portion is located between the skin-contact portion and the absorbent body.

[0011] The leak-proof folding edge preferably has a raised area in the crotch area, in which the raised piece is raised toward the wearer's skin by the contraction of an elastic member disposed on the skin-contacting part.

[0012] The leak-proof fold preferably has a non-standing area on at least one of the ventral side and the dorsal side, in which the standing piece is fixed to the absorbent body, and the skin-contact portion is fixed to the standing piece via the inner fixing portion of the fold.

[0013] Preferably, in the non-erect region, the skin side piece forming the skin contact surface and the non-skin side piece opposite to the skin side piece are not engaged, and the inner fixing part of the flange is located outside the two ends of the skin contact portion in the lateral direction.

[0022] Leak-proof gussets are components that come into contact with the wearer's skin while an absorbent garment is worn, preventing excrement from leaking out of the garment. There are concerns that excessive friction between the leak-proof gussets and the skin during wear may worsen their skin-touch feel, potentially leading to skin rashes. The absorbent garments described in Patent Documents 1 and 2 are insufficient in suppressing friction between the leak-proof gussets and the skin and improving skin-touch feel.

[0023] Therefore, the present invention relates to absorbent articles that can eliminate the disadvantages of the prior art described above.

[0024] Hereinafter, preferred embodiments of the absorbent articles of the present invention will be described. Figures 1-5 A unfolded disposable diaper (hereinafter, it will only be referred to as "diaper") is shown as one embodiment of the absorbent article of the present invention. Figure 1 The structure is shown when viewed from the skin-facing side of diaper 1.

[0025] Figure 1 The diaper 1 shown, in its unfolded and extended state, has a longitudinal direction X extending from the wearer's abdomen through the crotch towards the back, corresponding to the wearer's front-back direction, and a transverse direction Y orthogonal to the longitudinal direction X. The diaper 1 has: an abdominal portion A positioned on the wearer's abdomen when worn, and a dorsal portion B positioned on the back; and a crotch portion C located between the abdominal portion A and the dorsal portion B. Each region A, B, and C is a region that divides the entire length of the diaper 1 into three equal parts and extends continuously along the wearer's front-back direction. The crotch portion C has an excretion-facing portion (not shown) positioned opposite the wearer's excretory portion when the diaper 1 is worn.

[0026] like Figure 2 As shown, the diaper 1 includes: a liquid-permeable front sheet 2 forming the skin-facing side; a leak-proof sheet 3 forming the non-skin-facing side that is liquid-impermeable (also water-repellent); and a liquid-retaining absorbent body 4 disposed between the front sheet 2 and the leak-proof sheet 3, these components constituting an absorbent body 10.

[0027] The front panel 2 and the leak-proof sheet 3 are each larger than the absorbent body 4 and extend outward from the outer periphery of the absorbent body 4. The front panel 2 and the leak-proof sheet 3 extend outward from the two sides of the absorbent body 4 along the longitudinal direction X to the transverse direction Y. In this embodiment, the two ends of the front panel 2 and the leak-proof sheet 3 in each length direction are approximately aligned with the two ends of the diaper 1 in the length direction.

[0028] Diaper 1 includes a liquid-retaining absorbent body 4. Figure 1 The absorbent body 4 shown is arranged so that its length direction is aligned with the longitudinal direction X of the diaper, and extends from the ventral side A through the crotch C to the dorsal side B. The two sides of the absorbent body 4 in the length direction are located inward compared to the two sides of the longitudinal direction X of the diaper 1.

[0029] The absorbent 4 is formed by covering an absorbent core 40 with an absorbent chip (not shown) that has absorbent properties. The absorbent core 40 of this embodiment has a shape that is generally rectangular and longer in one direction, with its four corners cut off at an angle, and has a portion that tapers in the transverse direction Y at the crotch C.

[0030] In this specification, the "unfolded and elongated state" of diaper 1 refers to the state in which diaper 1 is unfolded, and the unfolded diaper 1 is extended to the point that the elastic components of each part are elongated to the designed size (the same size as when unfolded into a flat shape with the influence of the elastic components completely eliminated).

[0031] Furthermore, the "skin-facing side" refers to the side of the diaper or its components (such as the absorbent) that faces the wearer's skin when the diaper is worn, while the "non-skin-facing side" is the side of the diaper that faces the opposite side of the wearer's skin when the diaper is worn. In other words, the skin-facing side is the side relatively closer to the wearer's skin, and the non-skin-facing side is the side relatively farther from the wearer's skin. "While wearing" and "wearing state" refer to the state in which the diaper is worn to maintain the correct wearing position.

[0032] like Figure 1 As shown, in this embodiment, a pair of fastening straps 7, 7 are respectively provided on both sides of the waist wing portion WF of the back side portion B along the longitudinal direction X. Each fastening strap 7 is arranged to extend from both sides of the waist wing portion WF along the longitudinal direction X. One end of the inner side of the transverse direction Y of each fastening strap 7 is fixed between the sheet components constituting the diaper 1, for example, between the leak-proof sheet 3 and the outer sheet (not shown).

[0033] A fastening area (not shown) is provided on the non-skin-facing side of the diaper 1's ventral portion A, for detachable fastening by the fastening portion of the hook-and-loop fastener 7. The fastening area is made of a suitable material depending on the material of the fastening portion of the hook-and-loop fastener 7. For example, when the fastening portion is the male side material of a mechanical fastener, a fiber sheet capable of fastening with that male side material, such as woven fabric or non-woven fabric, can be used as the female side material of the mechanical fastener as the fastening area. Furthermore, when the fastening portion is an adhesive, a smooth film made of synthetic resin can be used as the fastening area, for example. For example, the outer sheet or other sheet components forming the non-skin-facing side of the diaper 1's ventral portion A can also serve as the fastening area.

[0034] The diaper 1 includes a pair of leak-proof flaps 6, 6 disposed along both sides of the absorbent body 10 in the longitudinal direction X. In this embodiment, the leak-proof flaps 6 have a raised area F2 at the crotch C where a raised portion 65 rises towards the wearer's skin (see reference). Figure 1 In the raised area F2, the leak-proof flange 6 is in an upright position. The raised area F2 is at least located at the crotch C.

[0035] like Figure 2 As shown, the leak-proof flange 6 is fixed to the absorbent body 10, and stands upright in the upright area F2 with the fixing part 23 fixed to the absorbent body 10 as the base end facing the wearer's skin side, becoming a free end.

[0036] Figure 2 The leak-proof fold 6 shown is not upright because it is in the unfolded and extended state of the diaper 1. However, when the extended state of the elastic member 61 used to form the fold is released and the diaper 1 is retracted, it becomes upright with the fixing part 23 as its base. In this embodiment, the base of the upright leak-proof fold 6 is located on the lateral outer side of the absorbent body 4. Hereinafter, the fixing part 23 forming this base will also be referred to as the "side fixing part 23".

[0037] The leak-proof flange 6 is composed of a water-repellent and breathable flange-forming sheet 16. In the leak-proof flange 6, one or more linear flange-forming elastic members 61 are arranged at the transverse inner end in a longitudinally elongated state X. By contracting the flange-forming elastic members 61, the leak-proof flange 6 stands up at least at the crotch C, thereby inhibiting the outward flow of excrement such as urine in the transverse Y.

[0038] The diaper 1 of this embodiment includes an outer cover (not shown) disposed on the non-skin-facing side compared to the leak-proof cover 3.

[0039] In this embodiment, the diaper 1 has an outer sheet disposed on the non-skin-facing side of the absorbent body 10. The outer sheet is a component that forms the outer surface of the diaper 1 when it is worn, making it visually recognizable from the outside. The outer sheet is disposed on the non-skin-facing side of the absorbent body 10 in a manner that extends from the ventral side A, through the crotch area C, to the dorsal side B. Furthermore, the outer sheet forms the shape of the diaper 1 in its unfolded and elongated state, and the periphery of the outer sheet forms the outlines of the ventral side A, the crotch area C, and the dorsal side B, respectively.

[0040] In the outline of the diaper 1 of this embodiment, the central side of the longitudinal direction X, i.e., the crotch C side, tapers in the transverse direction Y. Compared to the crotch C side, the ends of the abdominal side A and the back side B, respectively, extend laterally outward in the transverse direction Y. In other words, the cloth 1 of this embodiment has a wide portion in the abdominal side A and the back side B, and a tapered portion narrower than the width of the wide portion is located between these two wide portions in the longitudinal direction X.

[0041] The outer sheet extends from the two sides of the absorbent body 4 along the longitudinal X direction to the outer side of the transverse Y direction, forming the side wing SF together with the flange forming sheet 16 that constitutes the leak-proof flange 6.

[0042] The side wing portion SF is a component consisting of parts extending outward from both sides of the absorber body 4 along the longitudinal direction X in the transverse direction Y. In this embodiment, the side wing portion SF is composed of a flange forming sheet 16, a front sheet 2, a leak-proof sheet 3, and an outer sheet extending outward from the two sides of the absorber body 4 in the transverse direction Y. These sheets extend from the ventral side A, through the crotch area C, to the back side B, and extend outward from the two sides of the absorber body 4 in the transverse direction Y, respectively. These sheets are joined together at their extensions extending from the two sides of the absorber body 4 by known joining methods such as adhesives, heat sealing, and ultrasonic sealing.

[0043] In the diaper 1 of this embodiment, as Figure 1 As shown, the leg pleat forming elastic member 31 is arranged in an extended state on both sides of the diaper 1 along the longitudinal X direction, specifically on a pair of side wings SF, SF. Hereinafter, the leg pleat forming elastic member 31 will also be referred to as the leg elastic member. By contracting the leg elastic member 31, leg pleats are formed on the left and right sides of the wearer's legs, i.e., on both sides of the longitudinal X direction of the diaper 1. In this embodiment, the leg elastic member 31 is fixed in an extended state along the longitudinal X direction between the flange forming piece 16 and the leak-proof piece 3 in the side wing SF.

[0044] In this embodiment, the diaper 1 has a waist wing portion WF extending from the periphery of the absorbent body 4 outward in the longitudinal X direction or outward in the transverse Y direction at the end side of the longitudinal X direction of the back side portion B, specifically in the area between the front and rear ends of the longitudinal X direction of the wide portion of the back side portion B. The waist wing portion WF is a portion of the back side portion B that is formed by a component extending outward in the longitudinal X direction or outward in the transverse Y direction compared to the periphery of the absorbent body 4 at the end side of the longitudinal X direction. In this embodiment, the waist wing portion WF is composed of a flange forming sheet 16 extending outward from the periphery of the absorbent body 4, a front sheet 2, a leak-proof sheet 3, and an outer sheet. These sheets are joined together at their extensions from the periphery of the absorbent body 4 by known joining methods such as adhesive, heat sealing, or ultrasonic sealing. The waist wing portion WF corresponds to the wearer's waist when the diaper 1 is worn. The two sides of the transverse Y direction of the waist wing portion WF are also the front and rear ends of the longitudinal X direction of the side wing portion SF.

[0045] The structure of the leak-proof flange 6 in this embodiment will be described in detail. The leak-proof flange 6 in this embodiment is formed by folding a flange-forming sheet 16 multiple times along a crease along the longitudinal direction X. In this embodiment, the flange-forming sheet 16 is folded back at two creases; therefore, in a cross-sectional view along the transverse direction Y, the leak-proof flange 6 has folded-back portions formed by folding back the flange-forming sheet 16 at two locations. Of these two folded-back portions, the folded-back portion on the outer side of the transverse direction Y becomes the free end of the leak-proof flange 6, and the folded-back portion on the inner side of the transverse direction Y becomes the inner end of the leak-proof flange 6.

[0046] The leak-proof flange 6 of this embodiment has a strip-shaped skin-contact portion 63 on the free end side (see reference). Figure 2 The skin-contact portion 63 has a skin-contact surface 12 that contacts the wearer's skin when worn (see reference). Figure 2 The skin contact portion 63 includes: a skin side sheet 13 forming the skin contact surface 12; a non-skin side sheet 14 opposite to the skin side sheet 13; and an elastic member 61 for forming a flange disposed between the skin side sheet 13 and the non-skin side sheet 14.

[0047] The non-skin side panel 14 of this embodiment is formed by folding a sheet 16, which is continuous with the skin side panel 13, along the longitudinal direction X.

[0048] exist Figure 2 and Figure 3 The diagram illustrates a method where gaps are created between the inner ends of the pieces forming the leak-proof flange 6 in the transverse Y direction. However, the leak-proof flange 6 can also be formed by folding a single flange-forming piece 16 without creating gaps between the pieces. Furthermore, in Figure 3 In the leak-proof flange 6 of the non-standing area F1 shown, as described later, there may be no joint between the skin side panel and the non-skin side panel, thus creating a slight gap.

[0049] The leak-proof folding edge 6 of this embodiment has a raised section 65 located on the non-skin-facing side compared to the skin-contact portion 63 in the thickness direction Z of the diaper 1. The raised section 65 constitutes the raised portion of the leak-proof folding edge and is raised by the contraction of the folding edge forming elastic member 61 disposed on the skin-contact portion 63. Figure 2 and Figure 3 As shown, the upright portion 65 is located between the skin-contact portion 63 and the absorbent body 10 in the thickness direction Z of the diaper 1.

[0050] The stand-up piece 65 faces the skin-contacting part 63 in the thickness direction Z of the diaper 1, and has a side piece 17 extending laterally outward from the leak-proof flange 6 in the Y direction, and a main body side piece 18 located between the side piece 17 and the absorbent body 10. In this embodiment, the side piece 17 and the main body side piece 18 face each other in the thickness direction Z of the diaper 1 and are joined by a flange forming fixing part 62 formed between the two pieces 17 and 18.

[0051] The flange forming fixing part 62 is a fixing part that forms the upright piece 65, and is continuously formed along the entire length of the leak-proof flange 6 in the longitudinal direction X. Furthermore, the method of "the flange forming fixing part 62 being continuously formed along the entire length of the longitudinal direction X" includes not only the manner in which the flange forming fixing part 62 extends continuously in the longitudinal direction X, but also the manner in which the flange forming fixing part 62 is composed of a plurality of small fixing parts a, the small fixing parts a partially overlapping each other, and the small fixing parts a being arranged at intervals in a manner that is continuous along the entire length of the leak-proof flange 6 in the longitudinal direction X (see reference). Figure 8 ).For example, Figure 8 The flange forming fixing part 62 shown is configured such that each small fixing part a forming the flange forming fixing part 62 is inclined relative to both the longitudinal direction X and the transverse direction Y, and a portion of the small fixing parts a adjacent in the longitudinal direction X overlaps each other at the same position in the longitudinal direction X.

[0052] The leak-proof flange 6 of this embodiment has non-erected areas F1 on both the ventral side A and the dorsal side B. The leak-proof flange 6 of this embodiment also has non-erected areas F1 on both sides of the erected area F2 in the longitudinal direction X. Alternatively, the leak-proof flange 6 may have non-erected areas F1 on at least one of the ventral side A and the dorsal side B.

[0053] The non-erect region F1 is the region in the longitudinal direction X where no flange forming elastic member 61 is provided, or where the flange forming elastic member 61 is provided in a manner that does not exhibit elasticity or stretchability. In the latter region, the flange forming elastic member 61 does not exhibit elasticity or stretchability because it is subjected to cutting or other treatments or is not engaged with the flange forming piece 16 in an extended state.

[0054] like Figure 3 As shown, in the non-erect region F1, the erected portion 65 is fixed to the absorbent body 10 via the fixing portion 67, and the skin-contact portion 63 is fixed to the erected portion 65 via other fixing portions 60. Hereinafter, the fixing portion 60 that fixes the skin-contact portion 63 and the erected portion 65 will be referred to as the "flanged inner fixing portion" 60, and the fixing portion 67 that fixes the erected portion 65 and the absorbent body 10 will be referred to as the "body-side fixing portion" 67.

[0055] In the non-erect region F1 of this embodiment, the main body side plate 18 of the erect plate 65 is fixed to the front plate 2 of the absorbent main body 10 via the main body side fixing part 67.

[0056] In the skin-contact portion 63 of the non-erect region F1, the skin side piece 13 and the non-skin side piece 14 are not joined. That is, in the non-erect region F1, the skin side piece 13 and the non-skin side piece 14 are not joined together.

[0057] In the non-erect region F1, the inner flange fixing part 60 is located outside the two ends of the skin surface contact part 63 in the transverse Y direction. That is, the skin surface contact part 63 and the erecting piece 65 are not joined at the two ends of the skin surface contact part 63 in the transverse Y direction.

[0058] In the non-erect region F1, the elastic member 61 for forming the flange does not exhibit shrinkage, and the erecting piece 65 is fixed to the absorbent body 10 in the flange inner fixing part 60, so the erecting piece 65 does not stand up.

[0059] The non-erect area F1 of the ventral side A or dorsal side B is located on the wearer's waist when worn. Therefore, friction is likely to occur between this area and the wearer's skin due to the wearer's movements. When this friction is excessive, rashes may sometimes appear on the skin.

[0060] like Figure 3 As shown, in this embodiment, the skin-contact portion 63 of the non-erect region F1, the skin side piece 13 and the non-skin side piece 14 are not joined. On the other hand, the skin-contact portion 63 and the erect piece portion 65 are fixed by the flanged inner fixing portion 60. By adopting this structure, the skin contact surface 12 can be well maintained in the non-erect region F1, and the positions of the skin side piece 13 and the non-skin side piece 14 can be offset in the lateral Y direction (see reference). Figure 4 That is, the skin-side piece 13 has room to move in the transverse Y direction, so the skin-contact portion 63 follows the movement of the wearer's skin well and is less prone to friction. The inventors of the present invention have discovered that, especially when the inner fixing portion 60 of the folded edge is located outside the two ends of the skin-contact portion 63 in the transverse Y direction, the skin-side piece 13 is more likely to move from the inner fixing portion 60 of the folded edge when the skin-contact surface 12 is in contact with the skin. Moreover, since the inner fixing portion 60 of the folded edge is located between the skin-contact portion 63 and the upright piece portion 65, the tactile sensation of the inner fixing portion 60 of the folded edge, which is the joint portion between the pieces, is not easily transmitted to the skin, so a good skin feel can be obtained. Thus, in the diaper 1 of this embodiment, excessive friction between the leak-proof folded edge 6 and the skin can be effectively suppressed, and an excellent skin feel can be obtained.

[0061] The flanged inner fixing part 60 is a joining part that joins the non-skin side piece 14 of the skin-contact part 63 and the side piece 17 of the upright piece part 65. The flanged inner fixing part 60 can be formed by known joining methods such as adhesive, heat sealing, and ultrasonic sealing.

[0062] The flange forming fixing part 62, the main body side fixing part 67 and the side fixing part 23 can also be formed by the above-mentioned known joining method.

[0063] From the viewpoint of further improving the skin-following ability of the skin side plate 13 in the non-standing area F1, the length W2 of the inner fixing part 60 of the flange in the transverse Y direction (refer to) Figure 3 The length W1 of the skin contact surface 12 in the horizontal Y direction (refer to) Figure 3 The content is preferably 10% or more, more preferably 20% or more, and preferably 50% or less, more preferably 40% or less. It is also preferably 10% or more and 50% or less, more preferably 20% or more and 40% or less.

[0064] Regarding the same point of view as above, the length W1 of the skin contact surface 12 in the transverse Y direction (refer to...) Figure 3 The thickness is preferably 6mm or more, more preferably 12mm or more, and preferably 25mm or less, more preferably 18mm or less. It is also preferred that the thickness is 6mm or more and 25mm or less, and more preferably 12mm or more and 18mm or less.

[0065] From the viewpoint of further improving the shape retention of the skin-contact portion 63, the length W2 of the inner fixing portion 60 of the flange in the transverse Y direction (refer to...) Figure 3 The thickness is preferably 2mm or more, more preferably 3mm or more, and preferably 8mm or less, more preferably 6mm or less. In addition, it is preferably 2mm or more and 8mm or less, more preferably 3mm or more and 6mm or less.

[0066] From the viewpoint of further suppressing friction with the skin side plate 13 in the non-erect region F1, the distance D1 between the inner fixing portion 60 of the flange in the transverse Y direction and the end edge of the skin contact portion 63 in the non-erect region F1 (refer to...) Figure 3 The length W1 of the skin contact surface 12 in the horizontal Y direction (refer to) Figure 3 The content is preferably 10% or more, more preferably 20% or more, and preferably 50% or less, more preferably 40% or less. It is also preferably 10% or more and 50% or less, more preferably 20% or more and 40% or less.

[0067] Regarding the same point of view as above, the distance D1 between the inner fixing portion 60 of the flange in the transverse Y direction and the end edge of the skin contact portion 63 (refer to...) Figure 3The thickness is preferably 2mm or more, more preferably 3mm or more, and preferably 8mm or less, more preferably 6mm or less. In addition, it is preferably 2mm or more and 8mm or less, more preferably 3mm or more and 6mm or less.

[0068] The distance D1 between the two end edges of the flanged inner fixing portion 60 and the skin contact portion 63 in the transverse Y direction can be the same or different. In this embodiment, the distance between the inner end edge of the flanged inner fixing portion 60 and the skin contact portion 63 in the transverse Y direction is different from the distance between the outer end edge of the flanged inner fixing portion 60 and the skin contact portion 63 in the transverse Y direction.

[0069] From the viewpoint of further suppressing friction with the skin side panel 13 of the non-erect region F1, the length of the non-erect region F1 in the longitudinal X direction is preferably 5% or more, more preferably 10% or more, and further preferably 30% or less, more preferably 20% or less, and further preferably 5% or more and 30% or less, more preferably 10% or more and 20% or less. The length of the non-erect region F1 in the longitudinal X direction is the length of each non-erect region F1 in the longitudinal X direction.

[0070] Regarding the same viewpoint as above, the length of the non-erect region F1 in the longitudinal direction X is preferably 40 mm or more, more preferably 50 mm or more, and preferably 150 mm or less, more preferably 100 mm or less. In addition, it is preferably 40 mm or more and 150 mm or less, more preferably 50 mm or more and 100 mm or less.

[0071] The non-erect region F1, being a portion of the diaper 1 that is thicker than other parts, facilitates contact with the wearer's skin. From the viewpoint of reliably obtaining the aforementioned good skin feel in this portion that easily contacts the wearer's skin, the leak-proof gusset 6 preferably has a non-erect region F1 at the location overlapping with the absorbent body 4. In this case, the non-erect region F1 does not necessarily have to overlap the entire absorbent body 4; partial overlap is sufficient.

[0072] In this embodiment, the leak-proof flange 6 is formed by folding a flange forming sheet longitudinally at multiple points to create a skin-contact portion 63 and a raised portion 65. In the cross-sectional view along the transverse Y direction of the leak-proof flange 6, the skin-contact portion 63 and the raised portion 65 are connected via a folded-back portion of the flange forming sheet 16 on the inner side of the transverse Y direction (see reference). Figure 2In other words, the leak-proof flange 6 of this embodiment has a folded portion formed by folding the flange forming piece 16 back continuously to the outside of the transverse Y in a cross-sectional view along the transverse Y. The folded portion becomes the inner end of the skin-contact portion 63 in the transverse Y and the inner end of the upright piece 65 in the transverse Y. In the following text, the structure of the leak-proof flange in which the flange forming piece 16 is folded back continuously to the outside of the transverse Y in the cross-sectional view to form the skin-contact portion 63 will also be referred to as the "outward folding structure".

[0073] In this embodiment, the skin-facing side of the absorbent body 10 is formed of a sheet including a buffer layer CS. More specifically, the front sheet 2 includes a buffer layer CS on the skin-facing side.

[0074] The buffer layer CS of this embodiment is composed of a concave-convex region formed by multiple recesses and protrusions on one side (the skin-facing side) of the sheet. As a form of sheet with concave-convex regions, a structure can be described where a first sheet and a second sheet are joined together at multiple joints, and the first sheet protrudes away from the second sheet in areas other than the joints to form protrusions. The first and second sheets are preferably formed of fiber sheets, preferably nonwoven fabric, woven cloth, braided fabric, paper, or laminates thereof. Such a composite sheet can be manufactured, for example, by a method similar to that described in Japanese Patent Application Publication No. 2015-112343.

[0075] From the viewpoint of making the non-erect area F1 softer to the touch and further improving the skin feel, it is preferable that the inner flange fixing portion 60 is located on the skin-facing side of the absorbent body 10 at a position overlapping the buffer layer CS. In this case, the inner flange fixing portion 60 can be configured to partially overlap the buffer layer CS when viewed from above, but it is more preferable that the entire area of ​​the inner flange fixing portion 60 overlaps the buffer layer CS when viewed from above.

[0076] The diaper 1 of this embodiment has a back stretchable region 50 in the back side portion B, where an elastic member 51 extending in the transverse Y direction is arranged in an extended state. Multiple waist elastic members 51, fixed in an extended state in the transverse Y direction, are arranged between the sheets constituting the waist wing portion WF of the back side portion B. The waist folds are formed in the waist wing portion WF by the contraction of these elastic members 51. In this embodiment, the waist elastic members 51 are fixed between the leak-proof sheet 3 and the front sheet 2.

[0077] From the perspective of balancing the skin feel and fit of the non-erect region F1, it is preferable that the non-erect region F1 and the back stretchable region 50 overlap when viewed from above. In this case, partial overlap between the non-erect region F1 and the back stretchable region 50 is sufficient, but it is more preferable that the entire area of ​​the non-erect region F1 overlaps with the back stretchable region 50 when viewed from above.

[0078] In the non-erect region F1, other sheet components may also be disposed on its skin-facing side. For example, the skin-facing side of the non-erect region F1 may be partially covered by other sheet components. This approach is preferred in that it can further suppress leakage of excrement such as urine that moves along the skin-facing side of the absorbent body 10.

[0079] From the viewpoint of further improving this effect, it is preferable that the skin-facing surface of the longitudinal X-lateral end of the non-erect region F1 is covered by a separate sheet component.

[0080] From the viewpoint of further suppressing the leakage of excrement, the area of ​​the non-erect region F1 covered by the split piece is preferably 50 mm or more, more preferably 60 mm or more, extending from the outer edge of the longitudinal X towards the crotch C in the longitudinal X direction. Furthermore, it is preferably 160 mm or less, more preferably 110 mm or less. In addition, it is preferably 50 mm or more and 160 mm or less, more preferably 60 mm or more and 110 mm or less.

[0081] The separate sheet component can be any other sheet component or part thereof besides the sheet component that constitutes the leak-proof folding edge 6. Examples of other sheet components include auxiliary sheets, and examples of other sheet components include the folded portion formed by folding the outer sheet back at the longitudinal X end edge of the diaper 1 towards the skin side.

[0082] Figure 5 The area near the longitudinal X end edge e1 of the diaper 1 of this embodiment is shown (refer to...). Figure 1 Enlarged cross-sectional view of the leak-proof flange 6 along the transverse Y direction. Figure 5 This is an enlarged cross-sectional view of the leak-proof flap 6 before wearing.

[0083] like Figure 5 As shown, in the non-erect region F1 of this embodiment, the skin-side piece 13 and the non-skin-side piece 14 are quasi-fixed (temporarily fixed) at the longitudinal X-edge e1. At this edge, the skin-side piece 13 and the non-skin-side piece 14 are quasi-fixed to each other by pressing the two pieces 13, 14 together, and are fixed with a relatively weak strength to the extent that the non-erect region F1 can be peeled off as it follows the movement of the wearer's skin in the wearing state.

[0084] In this way, the skin side piece 13 and the non-skin side piece 14, which are quasi-fixed at the longitudinal X end edge e1 of the non-standing area F1, can be separated when worn, which can further improve the standing up of the leak-proof folding edge 6 when worn. From this point of view, it is preferred.

[0085] like Figure 3As shown, in the non-erect region F1 of this embodiment, in the cross-sectional view along the transverse direction, the inner flange fixing part 60 and the flange forming fixing part 62 are arranged to overlap in the transverse Y direction. That is, in the top view, the inner flange fixing part 60 and the flange forming fixing part 62 are arranged to overlap. By adopting this structure, it is possible to balance the skin-contact part 63's conformity to the skin and the uprightness of the leak-proof flange 6. In the top view, the inner flange fixing part 60 and the flange forming fixing part 62 can overlap either partially or over their entire area.

[0086] Furthermore, in the non-erect region F1 of this embodiment, in the cross-sectional view along the said transverse direction, the main body side fixing part 67 is also arranged overlappingly in the transverse Y direction with the flange inner fixing part 60 and the flange forming fixing part 62 (see reference). Figure 3 That is, when viewed from above, the inner flange fixing part 60, the flange forming fixing part 62, and the main body side fixing part 67 are arranged in an overlapping configuration. By adopting this structure, the skin side piece 13 follows the wearer's skin, making it easier to create an offset between the skin side piece 13 and the non-skin side piece 14 at the skin contact part 63, and enabling more reliable separation of the quasi-fixing part during wear. When viewed from above, the inner flange fixing part 60, the flange forming fixing part 62, and the main body side fixing part 67 can overlap either partially or over their entire area.

[0087] Figure 6 and Figure 7 Other embodiments of the leak-proof flange of the present invention are shown. (For details to follow...) Figure 6 and Figure 7 The illustrated implementation is to be consistent with Figures 1-5 The different components shown in the embodiments will be described primarily, with the same reference numerals used for the same components and their descriptions omitted. Components not specifically described can be appropriately referred to using the descriptions of the above embodiments.

[0088] In the aforementioned embodiments, the anti-leakage flange 6 is constructed by folding a flange forming piece 16 into an outward folded structure, but the structure of the anti-leakage flange is not limited to this form.

[0089] exist Figure 6 In the embodiments shown in (a) and (b), the leak-proof flange 6a has a skin-contact portion 63 and two overlapping raised portions 65a. The raised portion 65a has a skin-side raised portion 66 adjacent to the skin-contact portion 63 and a non-skin-side raised portion 69 adjacent to the absorbent body 10 in the thickness direction Z. These skin-side raised portions 66 and non-skin-side raised portions 69 overlap to form two layers.

[0090] The skin-contact portion 63, the skin-side raised portion 66, and the non-skin-side raised portion 69 are formed by folding a sheet 16 to form a flange.

[0091] In the stand-up piece 65a of this embodiment, the skin-side stand-up piece 66 faces the skin-contact portion 63 in the thickness direction Z of the diaper 1, and is connected to the skin-contact portion 63 near the center in the transverse direction Y. Thus, the cross-section of the skin-contact portion 63 and the skin-side stand-up piece 66 of the stand-up piece 65a in the transverse direction Y forms a T-shaped structure [see reference]. Figure 6 [of (a) and (b)].

[0092] In this embodiment, the non-skin-side upright sheet 69 is connected to the skin-side upright sheet 66 at the inner end of the leak-proof flange 6a in the transverse Y direction, and is formed by two sheets 17 and 18 that extend continuously from the inner end in the transverse outward direction. These two sheets are a side sheet 17 extending from the leak-proof flange 6a in the transverse Y direction and a main body side sheet 18 located between the side sheet 17 and the absorbent body 10. These side sheets 17 and main body side sheets 18 are opposite to each other in the thickness direction Z of the diaper 1.

[0093] In this embodiment, the connecting portion between the skin-side upright piece 66 and the non-skin-side upright piece 69 has a flange-forming fixing portion 62a formed by an adhesive or the like between the pieces forming the connecting portion. The flange-forming fixing portion 62a is disposed between the pieces 16 at the transverse Y-inner ends of the upright piece 65a forming an overlapping two-layer structure. More specifically, the flange-forming fixing portion 62a is disposed between the side piece 17 and the main body piece 18 in the non-skin-side upright piece 69, and between the pieces where the side piece 17 and the main body piece 18 are consecutive in the skin-side upright piece 66. With this flange-forming fixing portion 62a, the overlapping two-layer upright piece 65a can be raised towards the wearer's skin while maintaining the aforementioned T-shaped structure.

[0094] exist Figure 7 In the embodiments shown in (a) and (b), the leak-proof flange 6b has a skin-contact portion 63 and two overlapping raised portions 65b. The raised portions 65b have skin-side raised portions 66b and non-skin-side raised portions 69b in the thickness direction Z, and these portions 66b and 69b overlap to form two layers.

[0095] The skin-facing contact portion 63, the skin-side raised piece 66b, and the non-skin-side raised piece 69b are formed by folding a sheet 16 that is used to form a flange. The sheets forming the skin-side raised piece 66b and facing each other in the thickness direction Z, and the sheets forming the non-skin-side raised piece 69b and facing each other in the thickness direction Z, are respectively joined by a flange-formed fixing portion 62.

[0096] In this embodiment, the transverse Y position of the inner end of the skin-contact portion 63 and the upright portion 65b is the same, and the inner end of the transverse Y of these portions 63 and 65b forms the inner end of the transverse Y of the leak-proof flange 6b.

[0097] In this embodiment, the skin-side upright sheet 66b of the stand-up portion 65b faces the skin-contact portion 63 in the thickness direction Z of the diaper 1, and is connected to the skin-contact portion 63 at its outer end in the transverse Y direction. In this embodiment, the non-skin-side upright sheet 69b is connected to the skin-side upright sheet 66b at the inner end in the transverse Y direction of the leak-proof flange 6b, and is formed by a side sheet 17 and a main body side sheet 18 that are continuous from the inner end in the transverse outward direction. That is, the leak-proof flange 6b of this embodiment has a structure with a meandering cross-section in the transverse Y direction (see reference). Figure 7 [of (a) and (b)].

[0098] In the non-erect region F1 of this embodiment, the skin-side erected piece 66b, which constitutes part of the meandering structure, and the non-skin-side erected piece 69b are fixed together by a fixing part 68. In the non-erect region F1, the inner flange fixing part 60, the flange forming fixing part 62, the fixing part 68, and the main body-side fixing part 67 overlap in the transverse Y direction.

[0099] The forming materials of each part of the diaper in the above embodiment will be described in detail. As the front sheet 2, the leak-proof sheet 3, and the absorbent body 4, the materials that have been used in absorbent articles can be used without particular limitations.

[0100] For example, liquid-permeable nonwoven fabrics and perforated membranes can be used as the front sheet 2.

[0101] As a leak-proof sheet 3, it is possible to use a resin film that is difficult for liquid to pass through, a laminate of resin film and non-woven fabric, etc.

[0102] In the absorbent body 4, the absorbent core 41 can be made of an aggregate of hydrophilic fibers such as wood pulp or hydrophilically treated synthetic fibers, or a material made of a polymer that maintains the absorbency of the aggregate. Furthermore, the cover chip 42 can be made of the same material as the front sheet 2. Additionally, the edge-forming sheet 16 can be made of a water-repellent nonwoven fabric.

[0103] Furthermore, the outer sheath and the edge-forming sheet 16 can be made of nonwoven fabrics manufactured by various methods, such as spunbond nonwoven fabric, hot-air nonwoven fabric, spunlace nonwoven fabric, hot-roll nonwoven fabric, meltblown nonwoven fabric, or laminated nonwoven fabrics thereof. The outer sheath can be composed of a single sheet or, instead, a laminate of multiple sheets.

[0104] The elastic components such as the elastic member 61 for forming the flange, the elastic member 51 for the waist, and the elastic member 31 for the legs, which are disposed on the skin-contact portion 63 of the leak-proof flange 6, can use various known elastic materials commonly used in such absorbent articles without particular limitation. Examples of elastic materials include synthetic rubbers such as styrene-butadiene, butadiene, isoprene, and chloroprene rubber, natural rubber, EVA, stretchable polyolefins, and polyurethane. As for the shape of the elastic component, linear (rubber thread, etc.) or strip (rubber band, etc.) elastic components with cross-sections of rectangles, squares, circles, polygons, etc., are preferred, as are multi-fiber linear elastic components.

[0105] The present invention has been described above based on preferred embodiments, but the present invention is not limited to the above embodiments.

[0106] For example, in the above embodiment, the leak-proof flange 6 is formed by folding a single flange forming sheet 16, but it can also be formed by combining multiple flange forming sheets 16. In this manner, the skin-contact portion 63 and the skin-side raised sheet portion 66 and the non-skin-side raised sheet portion 69 can be formed from separate sheets, with the skin-side raised sheet portion 66 and the non-skin-side raised sheet portion 69 fixed by an adhesive or similar means.

Moreover, in the non-erect region F1, the flange forming fixing part 62 and the main body side fixing part 67 may not overlap when viewed from above.

[0108] Furthermore, while the aforementioned absorbent articles are so-called unfoldable disposable diapers with snap fasteners, the absorbent articles of the present invention also broadly include articles for absorbing bodily fluids (urine, loose stools, menstrual blood, sweat, etc.) excreted from the human body. Examples include shorts-type disposable diapers, incontinence pads, sanitary napkins, and menstrual panties.
