[0015] Hereinafter, a pants-type absorbent article 10 according to one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an external perspective view of the pants-type absorbent article 10 according to one embodiment of the present invention, seen from the front. Fig. 2 is a plan view of the pants-type absorbent article 10 of Fig. 1 in an unfolded state, seen from the skin side. Fig. 3 is a schematic enlarged view of part III of Fig. 2.

[0016] Note that the figures do not stipulate the relative dimensions of the constituent parts of the pants-type absorbent article 10, and the dimensions of each constituent part can be appropriately selected from a wide range depending on the purpose of the pants-type absorbent article 10, the age of the intended wearer, etc.

[0017] In this specification, the direction that faces the wearer's ventral side when the pant-type absorbent article 10 is worn is referred to as the "front side," and the direction that faces the wearer's back is referred to as the "rear side." Wearing the pant-type absorbent article 10 refers to the state in which the pant-type absorbent article 10 is worn on the body, regardless of whether it is before, during, or after absorption of bodily fluids. The pant-type absorbent article 10 is typically worn on the body inside clothing, but it may also be worn so that at least a portion of it is exposed to the outside. The vertical and horizontal directions of each component of the pant-type absorbent article 10 refer to the vertical direction when the article is worn by a wearer and the horizontal direction as seen from the wearer. The longitudinal direction of each component of the pant-type absorbent article 10 refers to the longitudinal direction (direction along the front and back) of the pant-type absorbent article 10 in an unfolded state (as shown in FIG. 2), which is the direction along arrow Y in FIG. 2. Furthermore, the width direction of each component of the pant-type absorbent article 10 refers to the direction (direction along the left and right) perpendicular to the longitudinal direction of the pant-type absorbent article 10 when it is unfolded, and is the direction along arrow X in Fig. 2. Furthermore, the thickness direction of each component of the pant-type absorbent article 10 refers to the direction in which each component is stacked. Furthermore, the skin side of each component of the pant-type absorbent article 10 refers to the direction toward the skin of the wearer when the pant-type absorbent article 10 is worn, and the non-skin side refers to the direction opposite to the skin side in the thickness direction. Furthermore, body fluids refer to liquids excreted from the body to the outside, such as urine, blood, and water in loose stools.

[0018] 1 and 2, a pants-type absorbent article 10 according to this embodiment includes an absorbent pad (absorbent main body) 20 having a generally belt-like shape in the front-to-rear direction that covers the crotch region of a wearer from the front, bottom, and back, and an exterior body 30 that overlaps the outside of the absorbent pad 20 and extends around the absorbent pad 20 to form the pants-like outer shape of the pants-type absorbent article 10. As will be described later, the exterior body 30 has a front waist region 31 that is located in front of the wearer's abdomen when worn, a rear waist region 32 that is located behind the wearer's back, and a crotch region 33 that is located between the wearer's legs. The absorbent pad 20 is mainly disposed on the inner side of the crotch region 33 of the exterior body 30, but a portion of it (front and rear ends) may extend into the front waist region 31 or the rear waist region 32 of the exterior body 30.

[0019] Preferably, the dimension of the pant-type absorbent article 10 in the longitudinal direction (the direction along arrow Y in Fig. 2) when unfolded is 600 mm or more and 1000 mm or less, and the dimension in the width direction (the direction along arrow X in Fig. 2) is 450 mm or more and 900 mm or less. By keeping the dimensions of the pant-type absorbent article 10 in the unfolded state within the above ranges, pant-type absorbent articles for adults in various sizes, such as small, medium, and large, can be provided.

[0020] The absorbent pad 20 includes a liquid-permeable top sheet 21 on the skin side, a liquid-impermeable back sheet 22 on the non-skin side, and an absorbent body 23 disposed between the top sheet 21 and the back sheet 22. As described above, in order to be able to provide pants-type absorbent articles for adults in various sizes, it is preferable that the longitudinal dimension of the absorbent pad 20 be 300 mm or more and 500 mm or less, and the width dimension be 100 mm or more and 300 mm or less.

[0021] The top sheet 21 may be formed from a liquid-permeable substrate that allows bodily fluids to move to the absorbent body 23. Examples of the substrate include nonwoven fabrics such as thermal-bonded nonwoven fabrics, composite nonwoven fabrics formed by laminating thermal-bonded nonwoven fabrics and spun-bonded nonwoven fabrics, apertured films such as apertured polyethylene films, foamed films such as polyethylene foam and urethane foam, and composite sheets formed by laminating these. Furthermore, the surface of the top sheet 21 may be embossed or perforated to improve liquid permeability. Such embossing or perforation may be achieved by any known method without limitation. Furthermore, the top sheet 21 may contain lotions, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, and the like to reduce irritation to the skin.

[0022] The basis weight of the top sheet 21 is set to 14 g / m from the viewpoints of strength, processability, and liquid return. 2 More than 40g / m 2 It is preferable that the thickness is 14 g / m or less. 2 If it is smaller, the top sheet 21 tends to be easily damaged during the production of the absorbent pad 20. 2 If it is larger, the top sheet 21 tends to feel hard when it contacts the skin, which is undesirable in either case. The shape of the top sheet 21 is not particularly limited, but it may be in any shape that covers the absorbent body 23 so as to guide bodily fluids to the absorbent body 23 without leakage.

[0023] The backsheet 22 may be formed using a liquid-impermeable substrate to prevent leakage of bodily fluids held in the absorber 23 to the non-skin side, and may be formed from a material such as a resin film or a composite sheet formed by laminating a resin film and a nonwoven fabric. The nonwoven fabric used in the composite sheet may be made by any method, and examples thereof include composite nonwoven fabrics formed by laminating multiple nonwoven fabrics of the same and / or different types, such as spunbond nonwoven fabric, meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric, and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, as well as composite materials thereof. Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0024] The basis weight of the back sheet 22 is set to 15 g / m from the viewpoint of strength and processability. 2 More than 60g / m 2 It is preferable that the back sheet 22 has a thickness of 1 / 4 or less. In addition, in order to prevent stuffiness during wear, it is preferable that the back sheet 22 has breathability. In order to make the back sheet 22 breathable, for example, a filler may be blended into the resin film of the base material or the back sheet 22 may be embossed. Note that an example of the filler is calcium carbonate, and the blending method can be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting kneaded product into a film, and removing the filler from the resulting film.

[0025] The absorber 23 includes a body fluid absorbing material, preferably a substrate and a body fluid absorbing material held in the substrate. The body fluid absorbing material is not particularly limited as long as it absorbs and holds body fluids, and examples thereof include fluff pulp and super absorbent polymer (SAP). The substrate of the absorber 23 is not particularly limited as long as it is a material generally used in absorbent articles such as sanitary napkins, diapers, and urine absorption pads, and is formed from materials such as fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabric. Among these, fluff pulp is preferably used from the viewpoint of absorbency. Examples of fluff pulp include wood pulp, synthetic fiber, polymer fiber, non-wood pulp, and the like that have been defibrated into a cotton-like state. The basis weight of the substrate of the absorber 23 is set to 100 g / m² to ensure good absorption performance and softness to the touch. 2 More than 800g / m 2 It is preferable to set the thickness to 100 g / m or less. 2 If it is smaller, it tends to absorb less body fluids such as urine, and 2 If it is larger than 100%, it tends to be difficult to stably manufacture the absorbent body 23, and either case is undesirable.

[0026] The SAP is not particularly limited as long as it can absorb body fluids and prevent backflow, and examples thereof include those formed from materials such as polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, polyacrylates are preferred from the viewpoint of absorption capacity per weight, and sodium polyacrylates are more preferred. The basis weight of the SAP of the absorbent body 23 is 50 g / m2 from the viewpoint of good absorption performance and feel against the skin. 2 More than 500g / m 2 It is preferable to keep it below 50g / m 2 If it is smaller, it tends to absorb less urine, and 2If it is larger, the yield of SAP tends to decrease when manufacturing the absorbent body 23, and either case is undesirable.

[0027] The absorbent body 23 preferably contains a substrate and SAP, and examples of its configuration include a substrate formed by mixing SAP particles into the substrate, and an SAP sheet in which SAP particles are fixed between substrates. From the viewpoint of preventing the SAP particles from falling off and stabilizing the shape of the absorbent body 23, it is preferable to wrap the absorbent body 23 in a carrier sheet. Alternatively, SAP may be formed into a fibrous form and mixed with the substrate. The substrate of the carrier sheet may be any hydrophilic material, such as tissue, absorbent paper, or a hydrophilic nonwoven fabric such as an air-laid nonwoven fabric. When the absorbent body 23 includes a plurality of carrier sheets, the substrates of the carrier sheets may be the same or different.

[0028] The shape of the absorber 23 is not particularly limited, and examples thereof include a rectangular shape, an hourglass shape, an I-shape, a rounded square shape with four rounded corners of a rectangle, an oval shape, an ellipse that is long in one direction, etc. The absorber 23 may be used by stacking two or more layers.

[0029] The absorbent pad 20 may include a pair of three-dimensional gathers (not shown) for preventing side leakage of bodily fluids. The three-dimensional gathers may have their outer ends in the width direction (direction along arrow X in FIG. 2) fixed to the skin-side surface of the backsheet 22, their middle portions in the width direction fixed to the skin-side surface of the topsheet 21, and their inner ends in the width direction serving as free ends extending on the skin-side surface of the topsheet 21. By configuring the three-dimensional gathers in this way, the areas near the free ends of the three-dimensional gathers are given the ability to stand up, allowing them to deform to fit the wearer's body shape.

[0030] 1 and 2, the exterior body 30 is a component that constitutes the outer shape of the pants-type absorbent article 10, and is formed by laminating nonwoven fabrics and stretchable members. In this embodiment, the exterior body 30 is formed by laminating an exterior nonwoven fabric sheet 34a on the non-skin side, an interior nonwoven fabric sheet 34b that is positioned on the skin side of the exterior nonwoven fabric sheet 34a, and a plurality of elastic stretchable members 35 that are interposed between the exterior nonwoven fabric sheet 34a and the interior nonwoven fabric sheet 34b. In addition to the exterior nonwoven fabric sheet 34a and the interior nonwoven fabric sheet 34b, an auxiliary sheet that covers the periphery of the absorbent pad 20 may be provided in the exterior body 30, and the auxiliary sheet may be laminated on the interior nonwoven fabric sheet 34b.

[0031] The exterior nonwoven fabric sheet 34a and the interior nonwoven fabric sheet 34b can be made of nonwoven fabric such as a thermal bonded nonwoven fabric, an air-through nonwoven fabric, or a spunbonded nonwoven fabric, preferably an air-through nonwoven fabric or a spunbonded nonwoven fabric made of a thermoplastic resin such as polypropylene, polyester, or polyethylene. When such a nonwoven fabric is used, its basis weight is 10 g / m 2 More than 40g / m 2 The following would suffice.

[0032] The outer cover 30 has a front waist region 31 located in front of the wearer's abdomen when worn, a back waist region 32 located behind the wearer's back, and a crotch region 33 located between the wearer's legs. The front waist region 31 and the back waist region 32 are regions that have side seals 36 on both sides in the width direction (regions that do not form leg openings 38a, 38b, described below), and the crotch region 33 is a region that does not have side seals 36 (regions that form leg openings 38a, 38b) (see FIG. 2).

[0033] As shown in Fig. 2, the exterior body 30 has a bilaterally symmetrical shape in an unfolded state before the side seals 36 on both sides of the widthwise sections of the front waistline region 31 and the back waistline region 32 are joined. The front waistline region 31 and the back waistline region 32 each have side seals 36 extending along the longitudinal direction at both widthwise ends, and are positioned at positions spaced apart from each other in the longitudinal direction. The crotch region 33 is a region located between the front waistline region 31 and the back waistline region 32. The absorbent pad 20 is joined to the interior nonwoven fabric sheet 34b in the crotch region 33 of the exterior body 30. The exterior body 30 is configured as a pair of detachable pants by joining the left and right side seals 36 of the front waist region 31 and the left and right side seals 36 of the rear waist region 32 together with the interior nonwoven fabric sheet 34b facing the skin, so that the left and right end edges of the front waist region 31 and the rear waist region 32 are continuous, as shown in Fig. 1. In the following description, the directions of the exterior body 30 refer to the directions when the pants are worn by a wearer.

[0034] 1 , the outer cover 30 has a waist opening 37 at the top of the front waistline region 31 and the back waistline region 32, leg openings 38a, 38b on both the left and right sides of the crotch region 33, and a perforation line 39 extending from the left-right center of the waist opening 37 in at least one of the front waistline region 31 and the back waistline region 32 (in this embodiment, the front waistline region 31) to the left and right leg openings 38a, 38b. The waist opening 37 is the portion through which the wearer's torso passes when worn, and is defined by the upper edge portions of both the front waistline region 31 and the back waistline region 32, and is stretchable in the circumferential direction. The left and right leg openings 38a, 38b are the portions through which the wearer's legs pass, and are defined by the left and right end edges of the crotch region 33, and are stretchable in the circumferential direction.

[0035] As shown in Figures 1 to 3, a plurality of elastic stretch members 35 that are stretchable in the circumferential direction of the waist opening 37 are provided in the front waist region 31 and the back waist region 32 at positions spaced apart from each other above and below. Each elastic stretch member 35 is joined to an exterior nonwoven fabric sheet 34a and an interior nonwoven fabric sheet 34b. The interior nonwoven fabric sheet 34b and each elastic stretch member 35 are preferably bonded to each other via a hot melt adhesive that is applied only to each elastic stretch member 35. The elastic stretch members 35 can be made of, for example, natural rubber, synthetic rubber, polyurethane, or the like in a thread, string, or flat shape, and their thickness is preferably between 300 dtex and 1500 dtex.

[0036] Of the multiple elastic stretchable members 35, the multiple elastic stretchable members 35a provided at the upper ends of the front waistline region 31 and the back waistline region 32 constitute a strip-shaped first stretchable region 40 that extends around the entire circumference of the waist opening 37 near the waist opening 37. That is, of the front waistline region 31 and the back waistline region 32, the front waistline region 31, where the cut line 39 is provided, has a strip-shaped first stretchable region 40 that is arranged around the waist opening 37 and is stretchable in the left-right direction, and the first stretchable region 40 is provided with elastic stretchable members 35a that are stretchable in the left-right direction. In this embodiment, the first stretchable region 40 extends around the entire circumference of the waist opening 37. The multiple elastic stretchable members 35a of the first stretchable region 40 are provided at positions spaced apart from each other vertically, and the vertical spacing L1 between each elastic stretchable member 35a is set to be approximately the same.

[0037] Of the multiple elastic stretchable members 35, multiple elastic stretchable members 35b arranged below the first stretchable region 40 in the front waistline region 31 form a strip-shaped second stretchable region 41 extending in the left-right direction at a position spaced downward from the first stretchable region 40 in the front waistline region 31. That is, of the front waistline region 31 and the back waistline region 32, the front waistline region 31 where the cutoff line 39 is provided has a second stretchable region 41 arranged downward from the first stretchable region 40 and stretchable in the left-right direction, and the second stretchable region 41 is provided with elastic stretchable members 35b that are stretchable in the left-right direction. The multiple elastic stretchable members 35b in the second stretchable region 41 are arranged at positions spaced apart from each other in the vertical direction, and the vertical spacing L2 between each elastic stretchable member 35b is set to be approximately the same distance.

[0038] The region 43 between the first elasticated region 40 and the second elasticated region 41 in the front waistline region 31 is an elastic stretchable member-free region (region between the first elasticated region and the second elasticated region) 43 that is not provided with any elastic stretchable members 35. The vertical length L3 of the elastic stretchable member-free region 43 (the vertical distance L3 between the second elasticated region 41 and the first elasticated region 40) is the vertical distance L3 between the lowest elastic stretchable member 35a in the first elasticated region 40 and the highest elastic stretchable member 35b in the second elasticated region 41, and is wider than the vertical distance L1 between the multiple elastic stretchable members 35a in the first elasticated region 40 and also wider than the vertical distance L2 between the multiple elastic stretchable members 35b in the second elasticated region 41. That is, the vertical length L3 of the elastic stretch member-free area 43 in the front waist region 31 is wider than the spacing between the elastic stretch members 35 in other locations (the vertical spacing L1 between the elastic stretch members 35a and the vertical spacing L2 between the elastic stretch members 35b).

[0039] Of the multiple elastic stretchable members 35, multiple elastic stretchable members 35c that are arranged below the first elastic stretchable region 40 of the rear waistline region 32 constitute a band-shaped third elastic stretchable region 42 that extends in the left-right direction at a position spaced downward from the first elastic stretchable region 40 of the rear waistline region 32. The multiple elastic stretchable members 35c of the third elastic stretchable region 42 are arranged at positions spaced apart from each other vertically, and the vertical spacing between each elastic stretchable member 35c is set to be approximately the same distance.

[0040] The cut line 39 provided on the exterior body 30 is formed in the shape of a perforation, with multiple slit-shaped cut portions 44 and multiple non-cut portions 45 arranged alternately (see FIG. 3 ). The cut portions 44 are thinner than the non-cut portions 45 (thinner portions in the thickness direction) or portions that penetrate the front waistline region 31, and extend along the direction in which the cut line 39 should extend. In other words, the cut line 39 is an easy-to-tear portion formed to make it easy to cut the front waistline region 31 along that line.

[0041] The cut line 39 in this embodiment is composed of a central cut line 39a extending downward from the left-right center of the waist opening 37 of the front waistline region 31, and left and right cut lines 39b, 39c branching from a lower end 46 of the central cut line 39a and continuing to the left and right leg openings 38a, 38b. The left-right center of the waist opening 37 of the front waistline region 31 is not limited to the left-right center of the waist opening 37 of the front waistline region 31. The cut line 39 may extend linearly or wavy.

[0042] The central cut line 39a extends linearly from the waist opening 37 of the front waistline region 31 to below the second elasticized region 41. That is, on both sides (left and right) of the central cut line 39a, there are elastically elasticized member-free regions 43 where no elastically elasticized members 35 are provided. The lower end 46 of the central cut line 39a is set at a height position higher than the absorbent pad 20 and the left and right leg openings 38a, 38b (higher than the lower ends of the side seal portions 36). The length of the central cut line 39a is preferably set to 15 cm or less.

[0043] The left and right cut lines 39b, 39c extend obliquely downward from the lower end 46 of the central cut line 39a toward the left and right leg openings 38a, 38b on both the left and right sides. That is, the cut lines 39 in this embodiment are formed in an inverted Y shape. The distance L4 between the outer ends of the left and right cut lines 39b, 39c and the lower end of the side seal portion 36 is set to a length between 0 and 15 cm. The left and right cut lines 39b, 39c are positioned higher than the absorbent pad 20. The distance L5 between the absorbent pad 20 and the cut lines 39 (in this embodiment, the left and right cut lines 39b, 39c) is preferably at least 1 cm.

[0044] An upper end portion (removal line end portion) 47 of the central cut line 39a and left and right outer end portions (removal line end portions) 48 of the left and right cut lines 39b, 39c are formed to be more difficult to cut than other regions (regions other than the cut line ends) 49 (regions 49 other than the upper end portion 47 and the left and right outer end portions 48) of the cut line 39. Note that the upper end portion 47 of the central cut line 39a and the left and right outer end portions 48 of the left and right cut lines 39b, 39c have substantially the same configuration, so the following description will focus on the upper end portion 47 of the central cut line 39a, and will omit a description of the left and right outer end portions 48 of the left and right cut lines 39b, 39c.

[0045] 2 and 3, the upper end 47 of the central cut line 39a is the portion of the cut line 39 that intersects with the first stretched region 40 (the portion above the elastically stretchable member-free region 43), where the length L6 of the cut portion 44 is shorter than the length L7 of the cut portion 44 in the other regions 49, and the length L8 of the non-cut portion 45 is longer than the length L9 of the non-cut portion 45 in the other regions 49. That is, at the cut line ends (upper end 47 and left and right outer end portions 48) on the waist opening 37 side and the left and right leg openings 38a, 38b side of the cut line 39, the cut portion 44 is shorter than the regions other than the cut line ends (the other regions 49), or the non-cut portions 45 are longer than the regions other than the cut line ends. This prevents the cut line 39 from accidentally tearing while being worn.

[0046] Next, we will explain how to dispose of a used pants-type absorbent article 10. Figure 4 is an explanatory diagram for disposing of a used pants-type absorbent article 10, where (a) shows the state before cutting, (b) shows the state after cutting, (c) shows the state in which the crotch region 33 is rolled up, and (d) shows the state in which it is tied.

[0047] When disposing of a used pants-type absorbent article 10, first, as shown in FIG. 4(a), the outer cover 30 (in this embodiment, the front waist region 31) of the pants-type absorbent article 10 while it is being worn by a wearer is cut along the cut lines 39 from the waist opening 37 to the left and right leg openings 38a, 38b. The front waist region 31, cut from the center in the left-right direction, is then opened to the left and right, and the used pants-type absorbent article 10 is removed from the wearer. At this time, the crotch region 33 may be left as it is without being opened downward (see FIG. 4(b)). Next, as shown in FIG. 4(b), from the state in which the front waist region 31 is opened to the left and right, the crotch region 33 is rolled up toward the inner surface (skin-facing surface) of the upper rear waist region 32. Next, as shown in FIG. 4(c), while maintaining the crotch region 33 in the rolled state, the opened front waist regions 31 are brought closer to each other. Next, as shown in Fig. 4(d), the cut left and right front waist regions 31 are tied together, and the crotch region 33 is kept rolled up. Finally, the used pants-type absorbent article 10 is discarded with the left and right front waist regions 31 still tied together.

[0048] The pants-type absorbent article 10 configured as described above has a cut line 39 that continues from the center in the left-right direction of the waist opening 37 of at least one of the front waistline region 31 and the rear waistline region 32 (in this embodiment, the front waistline region 31) to the left and right leg openings 38a, 38b. Since the cut line 39 continues from the waist opening 37 to the left and right leg openings 38a, 38b in this way, the used pants-type absorbent article 10 can be easily cut by hand.

[0049] Furthermore, because the cut line 39 extends from the center of the waist opening 37 in the left-right direction, when the front waist region 31 is cut along the cut line 39, the cut front waist region 31 can be secured long on both the left and right sides of the back waist region 32. For example, unlike when the front waist region 31 is cut at both the left and right ends of the front waist region 31 (near the left and right side seal portions 36 or the left and right side seal portions 36), the cut front waist region 31 can be secured long on both the left and right sides of the back waist region 32. Therefore, the cut front waist region 31 (the left and right front waist regions 31) can function as a portion for tying the used pant-type absorbent article 10, so the used pant-type absorbent article 10 can be rolled up and disposed of without the need for attached tape.

[0050] Furthermore, the central cut line 39a of the cut line 39 extends downward from the center of the waist opening 37 of the front waist region 31 to the center of the left and right sides of the front waist region 31, so that the front waist region 31 after cutting can be secured as long as possible on both the left and right sides of the back waist region 32.

[0051] Furthermore, the left and right cut lines 39b, 39c of the cut line 39 branch off from the lower end 46 of the central cut line 39a and extend obliquely downward toward the left and right leg openings 38a, 38b. That is, the height position of the lower end 46 of the central cut line 39a is set at a height position higher than the left and right leg openings 38a, 38b, and the left and right cut lines 39b, 39c extend obliquely downward on both sides from the lower end 46 of the central cut line 39a. Therefore, when the front waist region 31 is cut along the cut line 39 and opened to the left and right, a wide area can be left on the crotch region 33 side (the absorbent pad 20 side) upward, thereby preventing upward leakage of bodily fluids and the like. Furthermore, a wide area can be secured for arranging the absorbent pad 20.

[0052] Furthermore, at the ends of the cut line 39 on the waist opening 37 side and the left and right leg openings 38a, 38b side (top end 47 and left and right outer end 48), the cut portion 44 is shorter than the area other than the cut line ends (other areas 49), or the non-cut portion 45 is longer than the area other than the cut line ends. Therefore, the top end 47 and left and right outer end 48 of the cut line 39 are more difficult to cut than the other areas 49, and therefore the top end 47 and left and right outer end 48 of the cut line 39 can be prevented from tearing open unintentionally by the wearer, caregiver, etc.

[0053] Furthermore, since the distance L5 between the absorbent pad 20 and the cut lines 39 (in this embodiment, the left and right cut lines 39b, 39c) is at least 1 cm, it is possible to prevent the absorbent pad 20 from being accidentally cut when cutting the cut lines 39. This makes it possible to prevent leakage of bodily fluids due to cutting of the absorbent pad 20 when cutting the cut lines 39.

[0054] Furthermore, on both sides (left and right sides) of the central cut line 39a, there are elastically stretchable member-free regions 43 where no elastically stretchable members 35 are provided. Because no elastically stretchable members 35 are provided in the elastically stretchable member-free regions 43, the surface of the front waist region 31 can be easily pinched with fingers compared to the first stretchable region 40 and the second stretchable region 41 where the elastically stretchable members 35a and 35b are provided. Therefore, when cutting the exterior body 30 of the pant-type absorbent article 10 along the cut line 39 while it is being worn by a wearer, the surface of the elastically stretchable member-free region 43 in the front waist region 31 can be pinched and cut along the cut line 39 without inserting fingers inside the exterior body 30. In this way, the exterior body 30 can be cut along the cut line 39 without inserting fingers inside the exterior body 30 of the pant-type absorbent article 10 while it is being worn by a wearer, allowing the used pant-type absorbent article 10 to be disposed of hygienically.

[0055] Thus, according to this embodiment, the pants-type absorbent article 10 can be easily cut by hand, and the used pants-type absorbent article 10 can be rolled up and disposed of without the need for the attached tape.

[0056] In this embodiment, the elastic stretch member-free areas 43, where no elastic stretch member 35 is provided, are provided on both sides (left and right sides) of the cut line 39 of the front waistline area 31, but this is not limited to this. For example, the elastic stretch member 35 may be provided over the entire front waistline area 31 without providing the elastic stretch member-free areas 43.

[0057] In this embodiment, the cut portions 44 at the ends of the cut line 39 on the waist opening 37 side and the left and right leg openings 38a, 38b side (the upper end 47 and the left and right outer end portions 48) are shorter than those in other regions 49 (regions other than the cut line ends), and the non-cut portions 45 at the cut line ends are longer than those in other regions 49, but this is not limited to this. It is sufficient that the cut line ends of the cut line 39 have at least one of cut portions 44 that are shorter than those in other regions 49 and non-cut portions 45 that are longer than those in other regions 49. Alternatively, the entire cut line 39 may be formed by cut portions 44 and non-cut portions 45 of the same length.

[0058] In addition, in this embodiment, the cut line 39 is provided in the front waist region 31 of the outer casing 30, but this is not limited to this and it is sufficient that the cut line 39 is provided in at least one of the front waist region 31 and the rear waist region 32.

[0059] In addition, in this embodiment, the cutoff line 39 is formed in an inverted Y shape, but the cutoff line 39 is not limited to this.

[0060] FIG. 5 is a front view of the pants-type absorbent article 10 showing a first modified example of the cutting line 39. As shown in FIG.

[0061] As shown in Fig. 5, the cut line 39 may be formed in an inverted T shape. This cut line 39 is composed of a central cut line 39a extending downward from the left-right center of the waist opening 37 of the front waistline region 31, and left and right cut lines 39b, 39c branching from a lower end 46 of the central cut line 39a and continuing to the left and right leg openings 38a, 38b. The lower end 46 of the central cut line 39a is positioned above the absorbent pad 20 and below the lower ends of the side seal portions 36. The left and right cut lines 39b, 39c extend linearly from the lower end 46 of the central cut line 39a toward the left and right leg openings 38a, 38b in a direction perpendicular to the up-down direction. The distance L4 between the outer ends of the left and right cut lines 39b, 39c and the lower end of the side seal portion 36 is set to a length between 0 and 15 cm. In this case, the vertical length of the front waistline region 31 after cutting can be ensured to be long, so that when the front waistline region 31 after cutting is tied, the strength of the front waistline region 31 can be ensured and it can be tied firmly.

[0062] FIG. 6 is a front view of the pants-type absorbent article 10 showing a second modified example of the cutting line 39. As shown in FIG.

[0063] As shown in Fig. 6, the cut lines 39 may be formed in an inverted V shape. The cut lines 39 extend obliquely from the center of the waist opening 37 of the front waistline region 31 downward on both sides toward the left and right leg openings 38a, 38b. The cut lines 39 are composed of a left cut line 39d extending obliquely downward on the left side from the center of the waist opening 37 of the front waistline region 31 toward the left leg opening 38a, and a right cut line 39e extending obliquely downward on the right side from the center of the waist opening 37 of the front waistline region 31 toward the right leg opening 38b. The distance L4 between the outer ends (lower ends) of the left and right cut lines 39d, 39e and the lower ends of the side seal portions 36 is set to a length between 0 and 15 cm. The left and right cut lines 39d, 39e are positioned higher than the absorbent pad 20. In this case, when the front waist region 31 is cut along the cut lines 39 and opened to the left and right, a wide area can be left on the crotch region 33 side (the absorbent pad 20 side) upward, preventing upward leakage of bodily fluids and the like. Also, a wide area can be secured for arranging the absorbent pad 20. Note that the upper ends of the left and right cut lines 39d, 39e only need to be located in the center of the waist opening 37 of the front waist region 31 in the left-right direction, and may be positioned at the same position as each other or slightly spaced apart from each other laterally. However, in order to ensure the length of the left and right front waist regions 31 after cutting, it is preferable that the upper ends of the left and right cut lines 39d, 39e are positioned at the same position as each other.

[0064] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
