[Formation for carrying out the invention]

At least the following matters can be understood from the description of the present specification and the accompanying drawings.

An absorbent article comprising: a front-rear direction; a widthwise direction orthogonal to the front-rear direction; an absorber; a leg-opening portion disposed on both sides in the width direction, and configured in a wearing state And a leakage preventing sheet which is provided on the non-skin surface side of the absorbent body and which extends outward in the width direction of the absorbent body, and is characterized in that At least the front leg opening portion is provided with a moisture permeable sheet having a higher moisture permeability than the leakage preventing sheet on the skin surface side of the leakage preventing sheet, and the moisture permeable sheet has a moisture permeable sheet joined to the leakage preventing sheet. a joint portion and an inner hem that is detachable from the leakage preventing sheet without being joined to the leakage preventing sheet, wherein the inner hem extends outward from the rising base point in the width direction, and the inner hem has The first elastic member that expands and contracts in the front-rear direction.

Here, the base point is defined by the root of the inner hem, that is, the edge line starting from the erection of the inner hem. More specifically, it is a portion which is located most outward in the broad side direction of the root portion of the inner side hem in the underarm region, that is, according to the underarm region, the rising edge of the inner side hem is most located at the wide side The portion outside the direction is defined.

The absorbent article of this embodiment. The inner hem is raised from the leakage preventing sheet by the action of the first elastic member, and is easily adhered to the wearer's leg circumference. Thereby, in the sleeping posture and the sitting posture, in the region where the pressure resistance of the wearer is not received, since the leakage preventing sheet is separated from the wearer's leg circumference region, the air permeability of the leg circumference region is improved. Furthermore, since the inner hem has a higher moisture permeability than the leakage preventing sheet, the air permeability of the leg area is further improved.

Further, in general, when a wearer's sleeping posture applies pressure from the wearer's buttocks and thighs toward the vicinity of the absorbent body, the liquid easily leaks from the absorbent article due to the pressure. In the wearer's sleeping posture and the sitting posture, the wearer's thigh is pressed to push the vicinity of the leg opening portion of the absorbent article. In the absorbent article of the present embodiment, the wearer's sleeping posture and the sitting posture are such that the leakage preventing sheet is in close contact with the non-skin surface side of the inner hem by the pressure from the thigh. Thereby, the leakage preventing sheet suppresses leakage of the liquid from the region near the leg opening portion in the wearing posture and the sitting posture of the wearer.

As described above, according to the absorbent article of the present embodiment, it is possible to improve the air permeability of the region in the vicinity of the leg-opening portion while maintaining the effect of preventing leakage of the liquid from the region in the vicinity of the leg-opening portion.

According to one embodiment, the leakage preventing sheet has a second elastic member that expands and contracts in the front-rear direction on the inner side of the rising base point of the inner hem in the width direction.

In the wide-side direction, the contraction of the second elastic member existing on the inner side than the inner hem is made such that the inner side of the inner hem is easily along the circumference of the wearer's skin, whereby the inner hem is easier to fit. Around the wearer's legs. The inner hem is closely attached to the wearer's leg circumference, and leakage of liquid from the leg opening portion can be suppressed.

According to one embodiment, the present invention includes a front waist region disposed on a front side of a wearer, a back waist region disposed on a back side of the wearer, a buckle belt disposed in the back waist region, and a target portion. The hook portion is provided in the front waist region, and the target portion extends outward in the width direction from the rising base point of the inner hem.

In the wearing state, the outer side portion in the wide side direction of the front waist region is a portion that is rubbed against the back waist region or is easily affected by the movement of the wearer. Therefore, the outer side portion in the wide side direction of the front waist region is easily deformed during wearing. When the outer side portion in the widthwise direction of the front waist region is deformed in this manner, the influence is transmitted to the region near the leg opening portion, and the region near the leg opening portion may be curled. In the present embodiment, the rigidity of the outer portion of the front waist region is increased by the target portion extending outward from the base point of the inner hem, and therefore the deformation of the outer side portion of the front waist region in the widthwise direction is suppressed. Thereby, the curl of the region near the opening of the leg can be suppressed. Therefore, the outer portion of the front waist region is easily maintained in a state along the wearer's skin. As a result, the liquid from the vicinity of the opening of the leg can be more suppressed. Body leaks.

According to one embodiment, the moisture permeable sheet comprises: a first moisture permeable sheet; and a second moisture permeable sheet having a higher hydrophilicity than the first moisture permeable sheet provided on the non-skin surface side of the first moisture permeable sheet Sheet.

The hydrophilicity of the second moisture permeable sheet is higher than that of the first moisture permeable sheet facing the skin of the wearer. When the first moisture permeable sheet absorbs moisture from the wearer's skin, moisture easily moves from the first moisture permeable sheet toward the second moisture permeable sheet. Thereby, it is easy to release the wearer's sweat to the outside air. Further, the first moisture permeable sheet contacting the wearer's skin can be maintained in a drier state, and a comfortable absorbent article can be provided.

According to one embodiment, the distance from the rising base point to the outer edge of the leakage preventing sheet in the width direction is shorter than the distance from the rising base point to the outer edge of the moisture-permeable sheet in the width direction.

Since the distance from the rising base point of the inner hem to the outer edge of the leakage preventing sheet is relatively short, the outer edge of the leakage preventing sheet can be prevented from being tilted toward the non-skin surface side during the operation of the wearer. In this way, the outer edge of the leakage preventing sheet is prevented from being folded toward the non-skin surface side in the sleeping posture and the sitting posture of the wearer, and as a result, leakage of the liquid from the vicinity of the leg opening portion is easily suppressed.

According to one embodiment, the leakage preventing sheet is located outside the rising base point of the inner hem in the width direction, and has a front side in the front side in the width direction of the first elastic member. The second elastic member that is telescopic.

Leak-proof sheet in the wide side direction in the first round with the inside ruffle Since the position of the different members has the second elastic member, it is intended to contract differently from the inner hem. Thereby, the inner hem and the leakage preventing sheet can be easily separated.

According to one embodiment, the rising base point is located further inside than the edge of the absorber in the wide side direction.

Thereby, the inner hem can be separated from the leakage preventing sheet at the end of the absorbent body at least in the underarm region. Thereby, the air permeability is improved even at the end of the absorber. Therefore, it is possible to suppress rash or the like near the root of the wearer's leg.

According to one embodiment, the moisture permeable sheet is folded at an inner edge in the widthwise direction along a fold line along the front-rear direction, and the first portion on the skin surface side of the moisture permeable sheet and the moisture permeable sheet are The second portion on the non-skin surface side overlaps in the thickness direction of the absorbent article, and the second portion of the moisture permeable sheet is joined to the leakage preventing sheet.

Since the inner hem is formed by the folding of the moisture permeable sheet, the inner hem can be separated from the leakage preventing sheet by the force to be opened by the moisture permeable sheet.

According to one embodiment, the absorbent article has a front waist region disposed on the abdominal side of the wearer, a back waist region disposed on the back side of the wearer, and the front waist region and the back waist region. In the crotch region between the first portion of the moisture permeable sheet and the second portion of the moisture permeable sheet, at least the front waist region and the back waist region are joined to each other.

Because Part 1 and Part 2 are at least in the front waist area and Since the back waist regions are joined to each other, it is possible to suppress the inner hem or the outer edge of the leakage preventing sheet from warping toward the non-skin side. Thereby, the erection of the inner hem can be maintained at a necessary limit. Further, in the production of the absorbent article, since the inner hem or the outer edge of the leakage preventing sheet does not warp toward the non-skin surface side, the good product can be stably produced.

According to one embodiment, the first portion of the moisture permeable sheet and the second portion of the moisture permeable sheet are joined to each other at a joint portion provided along the fold line in the crotch region, and the joint portion is erected base point.

Since the first portion of the moisture permeable sheet and the second portion of the moisture permeable sheet are joined to each other at the joint portion, it is possible to suppress the inner hem or the outer edge of the leakage preventing sheet from warping toward the non-skin surface side. Thereby, the erection of the inner hem can be maintained at a necessary limit.

According to one embodiment, the absorbent article has a front waist region disposed on the abdominal side of the wearer, a back waist region disposed on the back side of the wearer, and the front waist region and the back waist region. In the underarm region, the moisture permeable sheet covers the entire absorbent body at least in the width direction, and the moisture permeable sheet is joined to the leakage preventing sheet in the crotch region or intermittently in the squat area. The provided joint portion is joined to the aforementioned leakage preventing sheet.

Even at this time, the outer side portion in the widthwise direction W of the moisture permeable sheet constitutes the inner hem which can be raised from the leakage preventing sheet. Therefore, as described above, it is possible to improve the air permeability of the region in the vicinity of the leg-opening portion while maintaining the effect of preventing leakage of the liquid from the region near the leg-opening portion. also, Since the moisture permeable sheet constituting the inner side hem is present on the non-skin side of the absorbent body, the air permeability of the area of the absorbent body can also be improved.

According to one embodiment, the moisture permeable sheet is joined to the leakage preventing sheet on both sides in the front-rear direction than the inner hem which can be raised from the leakage preventing sheet.

Since the moisture permeable sheet is joined to the leakage preventing sheet on both sides in the front-rear direction than the inner hem, it is possible to suppress the outer edge of the leakage preventing sheet from being tilted toward the non-skin surface side.

According to an embodiment, the joint portion extends partially in the front-rear direction in the crotch region.

The joint portion along the front-rear direction prevents the liquid from flowing in the wide-side direction in the underarm region. Thereby, side leakage of the liquid can be suppressed. On the other hand, since the joint portion partially extends in the front-rear direction, moisture is easily transmitted to the outside in the underarm region. Thereby, it is possible to achieve both the prevention of leakage of the liquid and the improvement of the air permeability.

According to one embodiment, the joint portion is at least a region on the rear side of the center of the absorbent article in the front-rear direction, and the outer portion of the absorbent body is larger than the outer edge of the absorbent body in the wide-side direction. The outer edge extends toward the inner side in the width direction.

The portion on the rear side than the center of the absorbent article in the front-rear direction is a region that faces the buttocks of the wearer or the upper portion thereof. Therefore, this area is under strong pressure in the posture in which the wearer sits and the wearer's sleeping posture. When the absorber that absorbs the liquid is subjected to a strong pressure, there is a concern that the liquid oozing out from the absorber leaks to the outer edge of the absorber in the widthwise direction. In the present embodiment, at least in the region on the rear side of the center of the absorbent article in the front-rear direction, the joint portion exceeds the outer edge of the absorber from the outer edge of the absorber in the widthwise direction toward the widthwise direction. The inner side extends, so that the sheets cannot stand up each other in a region where strong pressure is applied from the buttocks of the wearer. Thereby, since the area where the absorber liquid easily bleeds out is in contact with the leakage preventing sheet, leakage of the liquid can be suppressed.

The absorbent article according to the embodiment includes: a front-rear direction; a widthwise direction orthogonal to the front-rear direction; an absorber; and a leg-opening portion which are disposed on both sides in the width direction and are worn. The state is disposed in the leg circumference of the wearer; and the leakage preventing sheet is an absorbent article which is provided on the non-skin side of the absorbent body and extends outward in the width direction from the absorbent body. The at least the leg circumference opening portion is provided with a moisture permeable sheet having a higher moisture permeability than the leakage preventing sheet on the skin surface side of the leakage preventing sheet, and the moisture permeable sheet is in the width direction The outer side portion has an inner hem that is not joined to the leakage preventing sheet from the leak preventing sheet, and the inner hem has a first elastic member that expands and contracts in the front-rear direction.

In the absorbent article of the present embodiment, the inner hem is easily erected from the leakage preventing sheet by the action of the first elastic member 75, and is easily formed. To fit snugly around the wearer's legs. Thereby, in the sleeping posture and the sitting posture, in the region where the pressure resistance of the wearer is not received, since the leakage preventing sheet is separated from the wearer's leg circumference region, the air permeability of the leg circumference region is improved. Furthermore, since the inner hem has a higher moisture permeability than the leakage preventing sheet, the air permeability of the leg area is further improved.

Further, in general, when a wearer's sleeping posture applies pressure from the wearer's buttocks and thighs toward the vicinity of the absorbent body, the liquid easily leaks from the absorbent article due to the pressure. In the wearer's sleeping posture and the sitting posture, the wearer's thigh is pressed to push the vicinity of the leg opening portion of the absorbent article. In the absorbent article of the present embodiment, the wearer's sleeping posture and the sitting posture are such that the leakage preventing sheet is in close contact with the non-skin surface side of the inner hem by the pressure from the thigh. Thereby, the leakage preventing sheet suppresses leakage of the liquid from the region near the leg opening portion in the wearing posture and the sitting posture of the wearer.

As described above, it is possible to improve the air permeability of the region in the vicinity of the leg-opening portion while maintaining the effect of preventing leakage of the liquid from the region near the leg-opening portion.

Next, an absorbent article according to an embodiment will be described with reference to the drawings. In the present embodiment, the absorbent article is a disposable disposable diaper. In addition, in the description of the following drawings, the same or similar symbols are denoted by the same or similar parts. However, the figure is a schematic, and it is necessary to pay attention to the case where the ratio of each size is different from the actual one. Therefore, the specific dimensions and the like must be judged by referring to the following description. Moreover, even if the drawings are in mutual relationship with each other, the ratio may not be included. The same part.

(1) The overall schematic structure of disposable disposable diapers

Fig. 1 is a plan view showing a developed state of the disposable disposable diaper 10 of the embodiment. Fig. 2 is a plan view of the disposable disposable diaper 10 as seen from the opposite side of Fig. 1. Fig. 3 is a schematic cross-sectional view of the disposable disposable diaper 10 taken along line 3A-3A of Fig. 1. The top view shown in FIG. 1 and FIG. 2 is a view in which the elastic members 75, 76, and 77 are extended until the wrinkles of the top sheet 50 and the side sheets 70 of the disposable diaper 10 are not formed.

The disposable disposable diaper 10 has a front waist region 20, a crotch region 25, and a back waist region 30. The front waist region 20 is a portion that is disposed in the front waist portion (abdomen portion) of the wearer. Further, the back waist area 30 is a portion that is disposed on the wearer's rear waist portion (back portion). The underarm region 25 is located between the front waist region 20 and the back waist region 30. The crotch region 25 is a region in which the leg-opening portion 35 is provided. The leg-opening opening portion 35 is provided on both sides of the disposable disposable diaper in the widthwise direction W. The leg-opening portion 35 is a portion that is disposed along the wearer's leg circumference in a wearing state in which the disposable disposable diaper is worn by the wearer.

Further, in the present embodiment, the direction from the front waist region 20 toward the rear waist region 30 is referred to as the front-rear direction L. The widthwise direction W is a direction orthogonal to the front-rear direction L. The thickness direction T is a direction including the skin side T1 of the wearer and the non-skin side T2 of the wearer on the side opposite to the skin side T1.

The disposable diaper 10 has at least an absorbent body 40, a skin surface sheet disposed on the skin surface side T1 of the absorbent body 40, and a non-skin surface sheet disposed on the non-skin side T2 of the absorbent body 40. The absorber 40 is disposed at least in the underarm region 25. The absorbent body 40 has an absorbent core and a core cladding. The absorbent core comprises an absorbing material such as pulverized pulp, superabsorbent polymer (SAP) or the like. The core cladding is a sheet covering the absorbent core. The core cladding layer is composed of various fiber nonwoven fabrics or tissue sheets having liquid permeability.

The skin surface sheet has a top sheet 50 and a side sheet 70. The top sheet 50 is formed of a liquid permeable sheet such as a nonwoven fabric or a woven fabric. The top sheet 50 is a sheet that abuts the wearer's skin.

The side sheet 70 covers the outer edge of the top sheet 50 in the widthwise direction W, and extends outward in the width direction from the top sheet 50. The inner edge of the side sheet 70 in the widthwise direction W is folded outward in the widthwise direction. The third elastic member 77 that expands and contracts in the front-rear direction L is disposed in a region of the side sheet 70 that is folded over in two layers. The side sheet 70 and the third elastic member 77 constitute a leakage preventing side.

The non-skin surface sheet has at least a leakage preventing sheet 60a and an exterior sheet 60. The leakage preventing sheet 60a has liquid impermeability and is disposed on the non-skin side than the absorber 40. The leakage preventing sheet 60a extends outward in the width direction W from the absorber 40. The exterior sheet 60 is disposed on the non-skin side of the leakage preventing sheet 60a, and covers the leakage preventing sheet 60a.

The leakage preventing sheet 60a can be formed, for example, by a nonwoven fabric such as SMS. The moisture permeability of the leakage preventing sheet 60a is preferably in the range of 1,500 to 4,000 g/m ² /24 hr. The moisture permeability of the leakage preventing sheet 60a is 4000 g/m ² /24 hr or less, and the liquid absorbed by the absorber 40 can be prevented from leaking through the leakage preventing sheet 60a.

The disposable diaper 10 is provided with a buckle 90 in the back waist region 30. The buckle 90 is mounted on the side sheet 70. The buckle 90 extends in the back waist region 30 along the widthwise direction W. The buckle 90 has a catching portion 92 that is caught by the target portion 95 provided in the front waist region 20. By tying the engaging portion 92 of the buckle 90 to the target portion 95, the disposable disposable diaper 10 can be held in the wearer's body.

The disposable disposable diaper 10 has the moisture permeable sheets 64 and 70 on the skin surface side of the leakage preventing sheet 60a at least in the leg opening portion 35. The moisture permeable sheets 64, 70 have a higher moisture permeability than the leakage preventing sheets 60a. In the present embodiment, the moisture permeable sheets 64 and 70 are formed in two layers. One of the two layers of the moisture permeable sheets becomes a part of the side sheets 70. Instead of this embodiment, one of the two layers of the moisture permeable sheets may be composed of a sheet different from the side sheets 70.

The moisture permeable sheets 64 and 70 have a joint portion joined to the leakage preventing sheet 60a and an inner hem 74 which is not joined to the leakage preventing sheet 60a and can be raised from the leakage preventing sheet 60a. The inner hem 74 has a first elastic member 75 that expands and contracts in the front-rear direction L. The first elastic member 75 is disposed on the rising base point B1 or is disposed outside the wide side direction W more than this. The moisture permeable sheets 64 and 70 are contracted by the contraction force of the first elastic member 75, whereby the inner hem 74 is formed.

The inner hem 74 can stand up from the leakage preventing sheet 60a and extend outward from the rising base point B1 toward the wide side direction W. Here, the base point is established. B1 is defined by the root of the inner hem 74, that is, the edge starting from the erection of the inner hem 74.

In the present embodiment, the moisture permeable sheet 64 is folded in half. One side of the skin surface side of the moisture permeable sheet 64 is joined to the side sheet 70. The non-skin side of the moisture permeable sheet 64 is joined to the leakage preventing sheet 60a. The inner faces of the folded-through moisture permeable sheets 64 are not joined to each other. Thereby, the portion on the skin surface side of the moisture permeable sheet 64 can stand up from the leakage preventing sheet 60a.

The inner hem 74 rises from the leakage preventing sheet 60a by the action of the first elastic member 75, and is easily adhered to the wearer's leg circumference. Thereby, in the sleeping posture and the sitting posture, in the region where the pressure resistance of the wearer is not received, since the leakage preventing sheet 60 is separated from the wearer's leg area, the ventilation in the vicinity of the leg opening portion 35 is performed. Sexual improvement. Further, since the inner hem 74 has a higher moisture permeability than the leakage preventing sheet 60a, the air permeability of the region near the leg opening portion 35 is further improved.

Further, in general, when the wearer's sleeping posture or sitting posture applies pressure from the wearer's buttocks and thighs toward the vicinity of the absorbent body 40, the liquid easily leaks from the absorbent article due to the pressure. In the wearer's sleeping posture and sitting posture, the wearer's thigh is pressed to push the vicinity of the leg-opening portion 35 of the absorbent article. In the present embodiment, the wear preventing sheet 60a is brought into close contact with the non-skin surface side of the inner hem 74 by the pressure from the thigh in the wearing posture and the sitting posture of the wearer. Thereby, the leakage preventing sheet 60a suppresses leakage of the liquid from the vicinity of the leg-opening portion 35 in the wearing posture and the sitting posture of the wearer. As described above, according to the present embodiment, it is possible to maintain the liquid from the region near the leg opening portion 35 while maintaining the liquid. The effect of the leakage of the body increases the air permeability of the region near the leg opening portion 35.

In the present embodiment, the moisture permeable sheets 64 and 70 include the side sheet 70 as the first moisture permeable sheet, and the non-skin surface side provided on the first moisture permeable sheet having higher hydrophilicity than the first moisture permeable sheet 70. The second moisture permeable sheet 64 of the nature. The hydrophilicity of the second moisture permeable sheet 64 is higher than that of the first moisture permeable sheet 70 facing the wearer's skin. When the first moisture permeable sheet 70 absorbs moisture from the wearer's skin, moisture easily moves from the first moisture permeable sheet 70 to the second moisture permeable sheet 64. Thereby, it is easy to release the wearer's sweat to the outside air. Moreover, the first moisture permeable sheet 70 that contacts the skin of the wearer can be maintained in a drier state, and a comfortable absorbent article can be provided.

In the present embodiment, the second moisture permeable sheet 64 can be formed, for example, by an open water needle. When the side sheet 70 is composed of one sheet, the side sheet 70 is preferably formed of a sheet which has a function of maintaining leakproofness and exhibiting moisture permeability. As an example of such a sheet, an SMS nonwoven fabric or a hydrophobic spunbond nonwoven fabric can be mentioned.

Instead of the above embodiment, the side sheets 70 may be composed of at least two sheets. At this time, at least one sheet constituting the side sheet 70 overlaps with the second moisture permeable sheet 64. The remaining sheet constituting the side sheet 70 extends inward in the width direction W from the second moisture permeable sheet 64 to constitute the above-described leakage preventing side. At this time, the sheet constituting the leakage preventing side in the side sheet 70 may be formed, for example, of an SMS non-woven fabric having leakproofness, and the sheet overlapping the second moisture permeable sheet 64 of the side sheet 70 may be: A water needle, a hydrophilic spunbond non-woven fabric, a hydrophilic point-bonding non-woven fabric, and a hydrophilic hot air non-woven fabric are formed.

The distance W1 from the rising base point B1 to the outer edge of the leakage preventing sheet 60a in the width direction W is shorter than the distance W2 from the rising base point B1 to the outer edge of the moisture-permeable sheets 64, 70 in the width direction W. Since the distance W1 from the rising base point B1 of the inner hem 74 to the outer edge of the leakage preventing sheet 60a is relatively short, the outer edge of the leakage preventing sheet 60a can be prevented from tilting toward the non-skin side in the action of the wearer. Case. In this way, the outer edge of the leakage preventing sheet 60a is prevented from being folded toward the non-skin surface side in the sleeping posture and the sitting posture of the wearer, and as a result, the liquid from the region near the leg opening portion 35 is easily suppressed. The leak.

The leakage preventing sheet 60a has a second elastic member 76 that expands and contracts in the front-rear direction L in the widthwise direction W than the rising base point B1 of the inner hem 74. The second elastic member 76 is provided on the outer side in the widthwise direction W than the absorber 40. The contraction of the second elastic member 76 which is present inside the inner side hem 74 in the width direction W makes it easier for the inner side of the inner hem 76 to follow the periphery of the wearer's skin, whereby the inner side hem 76 is easier to fit snugly around the wearer's legs. The inner hem 76 is in close contact with the wearer's leg circumference, and leakage of liquid from the leg opening portion 35 can be suppressed.

The target portion 95 extends in the widthwise direction W and extends outward in the widthwise direction W from the rising base point of the inner hem 74. In the wearing state, the outer side portion of the front waist region 20 in the widthwise direction W is a portion that is rubbed against the back waist region 30 or is easily affected by the movement of the wearer. Therefore, the outer side of the widthwise direction W of the front waist region 20 is easy to wear. Deformed in a curved shape. If the outer portion of the front waist region 20 in the widthwise direction W is deformed in this manner, the influence is transmitted to the region near the leg opening portion 35, and the region near the leg opening portion 35 may be curled. In the present embodiment, since the rigidity of the outer portion of the front waist region 20 is increased by the target portion 95 extending outward from the rising base point B1 of the inner hem 74, the width direction W of the front waist region 20 is suppressed. The deformation of the outer portion can thereby suppress the curl of the region near the leg opening portion 35. Therefore, leakage of the liquid from the vicinity of the leg opening portion 35 can be more suppressed.

(2) Composition of the absorber

Next, an example of the configuration of the absorber 40 will be described with reference to Fig. 3 . The absorber 40 has a pair of first fold lines FL1 extending in the front-rear direction L and a pair of second fold lines FL2 extending in the front-rear direction. The absorber 40 is folded by a pair of first fold lines FL1 and a pair of second fold lines FL2. In the present embodiment, the absorber 40 is bent at four places by a pair of first folding lines FL1 and a pair of second folding lines FL2. Thereby, a part of the absorber 40 is overlapped by three layers in the overlapping portion 45. The outer edge 40E of the absorber 40 is composed of one layer of absorbent material and has a relatively thin thickness. Therefore, the feeling of discomfort in the wearer's leg circumference can be reduced.

The overlapping portion 45 is a portion between the first folding line FL1 and the second folding line FL2. Only one layer of absorbing material is disposed in a region between the pair of second fold lines FL2. The thickness of the absorber 40 is relatively thin in a region between the pair of second fold lines FL2, that is, in a central region in the widthwise direction W. Therefore, the central area is wider than the second fold line FL2 of the pair. The outer side of the side direction is recessed toward the non-skin side. Thereby, excrement (for example, urine) can be easily held in the central region of the absorbent body 40, and leakage of excrement can be suppressed, and the absorption capacity of excrement can be improved.

The basis weight of the absorbing material in the intermediate layer 43 sandwiched by the upper layer 41 and the lower layer 42 in the overlapping portion 45 is lower than the basis weight of the absorbing material in the upper layer 41 and the lower layer 42. Desirably, the intermediate layer 43 does not substantially have an absorbing material. Specifically, since the intermediate layer 43 has a design basis weight of the absorbing material of zero, the absorbing material constituting the upper layer 41 or the lower layer 42 is allowed to be mixed in the manufacturing process. When the intermediate layer 43 does not contain an absorbing material, the intermediate layer 43 is composed only of the core cladding described above. Since the basis weight of the absorbing material of the intermediate layer 43 and the basis weight of the absorbing material of the upper layer 41 and the lower layer 42 are relatively low, it is possible to suppress the thickness of the overlapping portion 45 from becoming excessively thick.

As shown in FIG. 3, the overlapping portion 45 of the absorbent body 40 does not engage the skin surface of the intermediate layer 43 and the non-skin surface of the upper layer 41. Further, the non-skin surface of the intermediate layer 43 and the skin surface of the lower layer 42 are not joined. Therefore, the upper layer 41 and the lower layer 42 are susceptible to forces in opposite directions. Therefore, when a force is applied from the outer side in the wide side direction W toward the inner side in the wide side direction W, the reaction force of the force is likely to occur, and the effect of lowering the rigidity of the absorber 40 is easily exhibited.

The joint portion A is composed of a region coated with the adhesive 80. In the third embodiment, the joint portion A constitutes a rising base point B1.

Since the first portion 64a of the moisture permeable sheet 64 and the second portion 64b of the moisture permeable sheet 64 are joined to each other at the joint portion A, it is possible to suppress the inner hem or the outer edge of the leakage preventing sheet from warping toward the non-skin surface side. Happening. Thereby, the standing of the inner hem 74 can be maintained at a necessary limit.

It is preferable that the joint portion A extends from the front waist region 20 to the back waist region 30 in the front-rear direction L. At this time, the adhesive 80 is ejected while the disposable disposable diaper 10 is conveyed in the front-rear direction L, and the adhesive 80 can be easily applied.

Figure 9 is a schematic cross-sectional view of the disposable disposable diaper taken along line 9A-9A of Figure 8. The same components as those of the above-described embodiment are denoted by the same reference numerals, and their description will be omitted. Hereinafter, a configuration different from the above embodiment will be described in detail.

In the fourth embodiment, the position of the rising base point B1 of the inner hem 74 is different as compared with the embodiment described with reference to Fig. 4 . The moisture permeable sheet 64 is folded at the inner edge in the widthwise direction W at a fold line along the front-rear direction L. Thereby, the first portion 64a on the skin surface side of the moisture permeable sheet 64 and the second portion 64b on the non-skin surface side of the moisture permeable sheet 64 overlap in the thickness direction T. The first portion 64a of the moisture permeable sheet 64 and the second portion 64b of the moisture permeable sheet 64 are joined to each other by at least the front waist region 20 and the back waist region 30 by the adhesive 80. Further, the region coated with the adhesive 80 is indicated by a region A marked with a diagonal line in FIG.

In the present embodiment, the first portion 64a of the moisture permeable sheet 64 and the second portion 64b of the moisture permeable sheet 64 are not joined to each other in the crotch region 25. Further, the rising base point B1 of the inner hem 74 is determined by the portion of the root portion of the inner hem 74 in the crotch region that is most outward in the width direction.

In the present embodiment, the rising base point B1 is located further inside than the edge portion 40E of the absorber 40 in the widthwise direction W (see FIG. 8). Thereby, the inner hem 74 can be separated from the leakage preventing sheet 60a at least at the crotch region 25 at the end of the absorbent body 40. Thereby, even at the end of the absorber 40, the air permeability is improved. Therefore, it is possible to suppress rash or the like near the root of the wearer's leg.

(7) Fifth embodiment

FIG. 10 is a plan view of the absorbent article according to the fifth embodiment as viewed from the non-skin surface side. Figure 11 is a schematic cross-sectional view of the absorbent article taken along line 11A-11A of Figure 10 . Figure 12 is a schematic cross-sectional view of the absorbent article taken along line 12A-12A of Figure 10 . The same components as those of the above-described embodiment are denoted by the same reference numerals, and their description will be omitted. Hereinafter, a configuration different from the above embodiment will be described in detail.

In the fifth embodiment, the moisture permeable sheet 64 covers the entire absorbent body 40 at least in the widthwise direction W. The moisture permeable sheet 64 may be joined to the side sheet 70 in the widthwise direction W and outside the absorber 40. The leakage preventing sheet 60a is provided on the non-skin side than the moisture permeable sheet 64.

As shown in FIGS. 10 and 11, the moisture permeable sheet 64 and the leakage preventing sheet 60a are joined to each other by at least the adhesive 80 at the front waist region 20 and the back waist region 30. Further, the region coated with the adhesive 80 is indicated by a region A marked with a diagonal line in FIG.

In the fifth embodiment, as shown in FIGS. 10 and 12, the moisture permeable sheet 64 is not joined to the leakage preventing sheet 60a at the outer portion in the width direction W of the crotch region 25. Even at this time, the outer side portion of the moisture permeable sheet 64 in the width direction W constitutes the inner hem which can be raised from the leakage preventing sheet 60a.

In the absorbent article according to the fifth embodiment, the inner hem is raised from the leakage preventing sheet 60a by the action of the first elastic member 75, and is easily adhered to the wearer's leg circumference. Thereby, in the sleeping posture and the sitting posture, in the region where the pressure resistance of the wearer is not received, since the leakage preventing sheet 60a is separated from the wearer's leg circumference region, the air permeability of the leg circumference region is improved. Further, since the inner hem has a higher moisture permeability than the leakage preventing sheet 60a, the air permeability of the leg area is further improved.

Further, in general, when the wearer's sleeping posture applies pressure from the wearer's buttocks and thighs toward the vicinity of the absorbent body 40, the liquid easily leaks from the absorbent article due to the pressure. In the wearer's sleeping posture and the sitting posture, the wearer's thigh is pressed to push the vicinity of the leg opening portion of the absorbent article. In the absorbent article of the present embodiment, the leakage preventing sheet 60a is brought into close contact with the non-skin surface side of the inner hem 74 by the pressure from the thigh in the sleeping posture and the sitting posture of the wearer. Thereby, the leakage preventing sheet 60a suppresses leakage of the liquid from the vicinity of the leg opening portion in the wearing posture and the sitting posture of the wearer. According to the absorbent article of the fifth embodiment, the air permeability of the region near the leg opening portion can be improved while maintaining the effect of preventing leakage of the liquid from the region near the leg-opening portion.

As described above, the moisture permeable sheet 64 and the leakage preventing sheet 60a are at least The front waist region 20 and the back waist region 30 are joined to each other by the adhesive 80. Since the moisture permeable sheet 64 is joined to the leakage preventing sheet 60a on both sides in the front-rear direction than the inner hem, the outer edge of the leakage preventing sheet 60a can be prevented from being tilted toward the non-skin surface side.

The portion 81 of the joint portion along the front-rear direction prevents the liquid from flowing in the wide-side direction W in the underarm region 25. Thereby, side leakage of the liquid can be suppressed. On the other hand, since the joint portion is only partially extended in the front-rear direction, moisture is easily transmitted to the outside in the underarm region 25. Thereby, it is possible to achieve both the prevention of leakage of the liquid and the improvement of the air permeability.

It is preferable that at least one of the portions 81 of the joint portion along the front-rear direction is disposed outside the absorbent body 40 in the widthwise direction W. borrow Thereby, it is possible to prevent the liquid absorbed by the absorber 40 from flowing toward the outside in the wide direction W.

Further, it is preferable that the portion 81 having the joint portion on an arbitrary line extending in the width direction W of the crotch region 25 is present. In other words, it is preferable that the crotch region 25 is formed such that the joint portion A does not exist at all in a straight line along the width direction W. Thereby, it is possible to further suppress the flow of the liquid toward the outside of the wide side direction W.

The rising base point B1 of the inner hem is the portion of the root of the inner hem in the crotch region 25 which is most outward in the width direction, that is, by the hem of the inner hem in the underarm region 25 The portion of the starting edge line that is most outside the broad side direction is defined. In other words, in the sixth embodiment, the rising base point B1 is defined by the portion of the portion 81 of the joint portion in the crotch region 25 that is most outward in the width direction (see FIG. 13).

Further, in the sixth embodiment, the portion 81 of the joint portion extends in parallel with the front-rear direction L. Instead of the above configuration, the portion 81 of the joint portion may be inclined from the front-rear direction L as long as it is along the front-rear direction L.

(9) Seventh embodiment

Fig. 14 is a view showing a region where a moisture permeable sheet and a leakage preventing sheet are joined to each other in the absorbent article according to the seventh embodiment. The same components as those in the fifth embodiment are denoted by the same reference numerals, and their description will be omitted. Hereinafter, a configuration different from the above embodiment will be described in detail.

In the seventh embodiment, the region A of the joint portion between the moisture permeable sheet 64 and the leakage preventing sheet 60a is different from that of the fifth embodiment. in In the seventh embodiment, the moisture permeable sheet 64 is joined to the leakage preventing sheet 60a at the joint portion A where the underarm region 25 is intermittently provided.

The joint portion A has a portion 81 that partially extends in the fore and aft direction in the underarm region. The portion 81 extending partially along the front-rear direction of the joint portion A is provided at a plurality of intervals in the width direction W.

The end portion of the portion 81 extending along the front-rear direction of the joint portion A is curved toward the inner side in the widthwise direction W. Thereby, that is, the portion 81 of the joint portion has a shape that catches the liquid from the center in the widthwise direction W toward the outside. Thereby, it is possible to further suppress the flow of the liquid toward the outside of the wide side direction W.

Further, in the seventh embodiment, the portion 81 of the joint portion extends in parallel with the front-rear direction L. Instead of the above configuration, the portion 81 of the joint portion may be inclined from the front-rear direction L as long as it is along the front-rear direction L.

(10) Eighth embodiment

Fig. 15 is a view showing a region where a moisture permeable sheet and a leakage preventing sheet are joined to each other in the absorbent article according to the eighth embodiment. The same components as those in the fifth embodiment are denoted by the same reference numerals, and their description will be omitted. Hereinafter, a configuration different from the above embodiment will be described in detail.

In the eighth embodiment, the region A of the joint portion between the moisture permeable sheet 64 and the leakage preventing sheet 60a is different from that of the fifth embodiment. In the eighth embodiment, the moisture permeable sheet 64 is joined to the leakage preventing sheet 60a at the joint portion A provided at the crotch region 25 at a portion.

a joint portion 82 of the moisture permeable sheet 64 and the leakage preventing sheet 60a to The region which is less on the rear side than the center C of the absorbent article in the front-rear direction L extends beyond the outer edge of the absorbent body 40 in the widthwise direction W beyond the outer edge of the absorbent body 40 toward the inner side in the widthwise direction. . The joint portion 82 may also reach the front side more than the center C in the front-rear direction L. In the embodiment shown in Fig. 15, the joint portion 82 is provided on the inner side of the outer edge of the absorber 40 in the widthwise direction.

The joint portion 82 is at least a region on the rear side of the center C of the absorbent article in the front-rear direction L, and is preferably only 1.5 cm, more preferably only 1.0 cm, more preferably than the outer edge of the absorber 40 in the widthwise direction W. It is desirable that the distance within a distance of only 0.5 cm reaches the outer side in the wide side direction.

The portion on the rear side than the center C of the absorbent article in the front-rear direction L is a region facing the buttocks of the wearer or the upper portion thereof. Therefore, this area is under strong pressure in the posture in which the wearer sits and the wearer's sleeping posture. When the liquid absorbing body 40 is subjected to a strong pressure, there is a concern that the liquid oozing from the absorber 40 leaks to the outer edge of the absorber 40 in the widthwise direction. In the present embodiment, the region is at least rearward than the center C of the absorbent article in the front-rear direction L, and the joint portion 82 exceeds the absorber 40 from the outer edge of the absorber 40 in the widthwise direction W. Since the outer side edge extends inward in the width direction W, the sheets cannot stand up from each other in a region where strong pressure is applied from the buttocks of the wearer. Thereby, the area where the liquid of the absorber 40 is easily oozing out is in contact with the leakage preventing sheet 60a, so that leakage of the liquid can be suppressed.

The rising base point B1 of the inner hem is the portion of the root of the inner hem in the underarm region 25 which is located most outward in the broad direction, and In other words, in the crotch region 25, the portion of the inner hem of the inner hem that is most outward in the width direction is defined. In other words, in the eighth embodiment, the rising base point B1 is defined by the portion of the portion 82 of the joint portion in the crotch region 25 that is most outward in the width direction (see Fig. 15).
