[ Summary of invention ]

[Technical problem]

[0004]

When the wearer of the pull-on disposable diaper is an infant who has a small body size, if the lift height of the leakage protection wall is too large, there is a tendency for a large gap to be formed between the body and the diaper. In this case, the excreted urine and the like are not easily absorbed by the absorbent body, and the urine tends to flow out from the front side. On the other hand, if the lift height of the leakage barrier wall is small, there is a risk that excreted feces adhering to the surface of the absorbent body will "overflow" from the rear side and flow out of the diaper.

[0005]

The present invention has been made in view of known problems such as those described above, and it is an object of the present invention to provide a pant-shaped absorbent article which can easily suppress the leakage of secretions from the front side and the back side.

wherein the pant-shaped absorbent article includes:

absorbent body; and

two leakage-proof walls which are provided on two sides of the absorbent body and which are movable towards the skin side,

wherein the first starting point of the rise is inside in a lateral direction with respect to the second starting point of the rise,

wherein the first starting point of the rise is the starting point from which each leak-proof wall rises at a first point which is located at least on the side front in the front-to-back direction with respect to the center in the front-to-back direction,

wherein the second lifting start position is the starting position from which the leak-proof wall is lifted at the second position, which is on the side rearward in the front-to-back direction with respect to the first position.

[0007]

According to a second aspect of the present invention, for solving the problem described above, there is provided a pant-shaped absorbent article having a vertical direction, a lateral direction, and a forward-backward direction that intersect each other,

wherein the pant-shaped absorbent article includes:

absorbent body;

front waist; and

back waist,

wherein the two side end portions of the front waist portion are connected to the two side end portions of the rear waist portion, whereby a waist opening is formed,

while the absorbent body has two walls that protect against leakage,

wherein these two leakage-proof walls are liftable towards the wearer's skin side from the two sides of the absorbent body,

wherein, if the pant-shaped absorbent article is viewed from above in a state in which the waist opening is expanded from the natural state in the front-to-back direction and in the side direction, then

that part of each leakage protection wall whose lifting height towards the skin side is the largest is located on the rear side in the front-to-back direction.

[ Description of Embodiments ]

[0010]

At least the following objects will be made clear through the description in this specification and the accompanying drawings.

A pant-shaped absorbent article having a vertical direction, a lateral direction, and a front-to-back direction that intersect each other,

wherein the pant-shaped absorbent article includes:

absorbent body; and

two leakage protection walls which are provided on two sides of the absorbent body and which are designed to be liftable towards the skin side,

wherein the first starting point of the rise is inside in a lateral direction with respect to the second starting point of the rise,

wherein the first starting point of the rise is the starting point from which each leak-proof wall rises at a first point which is located at least on the side front in the front-to-back direction with respect to the center in the front-to-back direction,

wherein the second lifting start position is the starting position from which the leak-proof wall is lifted at the second position, which is on the side rearward in the front-to-back direction with respect to the first position.

[0011]

In such a pant-shaped absorbent article, allowing the leakage barrier wall to rise to a great height at the second location on the rear side allows a large space in which feces can be held between the absorbent body and the wearer's body to be able to suppress fecal leaks. Limiting the lifting height of the leakage protection wall at the first position on the front side makes it possible to easily suppress leakage of urine in the lateral direction, and at the same time makes it possible to reduce the gap between the absorbent body and the body of the wearer, so that urine can be easily absorbed. Thus, it is possible to provide a pant-shaped absorbent article which can easily suppress the leakage of secretions from the front side and from the back side.

[0012]

In the case of such an absorbent pant-shaped article,

the pant-shaped absorbent article further comprises an absorbent body including an absorbent body,

each of the two anti-leak walls is connected to the absorbent body by means of a first connection zone, a second connection zone and a third connection zone,

- wherein the first connecting zone is a zone provided in the outer in the lateral direction, the end part and extending in the vertical direction,

- the second connection zone is an area provided in each of the front upper end part and the rear upper end part of the absorbent body and inside in a lateral direction with respect to the first connection zone,

- the second connection zone secures the leakage protection wall so that it cannot rise,

- the third connecting zone is a zone provided at least

-- between the lower end of the second connection zone, which is provided in the front upper end of the absorbent body, and the lower end of the absorbent body, defined in the vertical direction, and

-- between the first connection zone and the second connection zone in the lateral direction.

[0013]

In such a pant-shaped absorbent article, it can be ensured that the lift height of that part of the leakproof wall that starts to rise in the third bonding zone can be less than the lift height of that part of the leakproof wall that starts to rise in the first bonding zone. Accordingly, the proper execution of the connecting zones enables more effective suppression of the leakage of secretions from the front side and the rear side.

[0014]

In such an absorbent pant-shaped article, it is desirable that

the first location was a location that overlaps the third connection area in the vertical direction.

[0015]

In such a pant-shaped absorbent article, changing the location and length of the third bonding zone in the vertical direction (front-to-back direction) makes it possible to adjust the zone in which the lift height of the leakage barrier wall is small. Thus, it is possible to provide an absorbent article having a leakage-proof wall that can more easily adhere to the wearer's body according to the size and the like of the wearer's body.

[0016]

In such an absorbent pant-shaped article, it is desirable

that the pant-shaped absorbent article further comprises a front waist portion and a rear waist portion, and

so that the lower end of the third connecting zone is located in the vertical direction lower than the lower end of the rear waist portion.

[0017]

In such a pant-shaped absorbent article, by allowing the leakage barrier wall to rise in the region below the rear waist portion, it is possible to form a portion having a higher maximum liftable height where the leakage barrier begins to rise in the first connection region, and the portion , having a small maximum lifting height, where the leakage protection wall begins to rise in the third connection zone. Thus, the leakage of secretions can be effectively suppressed.

[0018]

In such an absorbent pant-shaped article, it is desirable that

the lower end of the third bonding zone was located on the side front in a front-to-back direction with respect to the lower end of the absorbent body.

[0019]

In such a pant-shaped absorbent article, when the wearer wears the pant-shaped absorbent article, it is possible to increase the area in which the leakage barrier wall rises to a high height from the starting point of the rise, which is in the first bonding area. Thus, it is possible to increase the space in which feces can be held, and leakage of feces from the rear area can be more easily suppressed.

[0020]

In such an absorbent pant-shaped article, it is desirable

that the pant-shaped absorbent article further comprises a front waist portion and a rear waist portion, and

so that the upper end of the third connecting zone is located in the vertical direction higher than the lower end of the front waist portion.

[0021]

In such an absorbent article in the form of a pant, in a large portion of the zone in which the waist tightening force generated by the front waist portion is not applied, it is possible to cause the leakage protection wall to rise towards the skin side from the starting point of the rise, which is located in the third connection zone. . Thus, leakage of urine and the like in the lateral direction from the front region of the pant-shaped absorbent article can be effectively suppressed.

[0022]

In such an absorbent pant-shaped article, it is desirable that

the upper end of the third bonding zone was located in the vertical direction higher than the lower end of the second bonding zone, which is located in the front upper end portion of the absorbent body.

[0023]

In such a pant-shaped absorbent article, at the front side of the pant-shaped absorbent article, between the lower end of the front second connection zone and the lower end of the third joint zone, it is possible to allow the leakage barrier wall to rise over a larger area while limiting the lifting height of the leakage barrier wall so that this the height was not excessive. Accordingly, leakage of urine and the like in the lateral direction can be effectively suppressed.

[0024]

In such an absorbent pant-shaped article, it is desirable that

the upper end of the third bonding zone was located in the vertical direction lower than the upper end of the second bonding zone, which is located in the front upper end portion of the absorbent body.

[0025]

In such a pant-shaped absorbent article, it is possible to reduce the area of that overlapping part of the third connection zone which overlaps the front second connection zone in the vertical direction. Reducing the area of the overlapping portion does not affect the function of adjusting the height of the leakproof wall, and therefore reducing the amount of adhesive to form the third bonding zone makes it possible to reduce costs without impairing the function of the leakproof wall. In addition, this makes it possible to improve the texture of the pant-shaped absorbent article.

[0026]

In such an absorbent pant-shaped article, it is desirable

so that the absorbent body includes an absorbent core that absorbs liquids,

so that the absorbent core includes a narrow part between two parts of the absorbent core, end in the longitudinal direction,

- while the narrow part has a smaller length in the lateral direction, and

so that the upper end of the third connection zone is located in the vertical direction higher than the narrow part of the absorbent core.

[0027]

In such a pant-shaped absorbent article, it is possible to reduce the distance in the lateral direction between the third connection zone and the absorbent core, which has a high rigidity compared to other parts. This reduces the likelihood of stress and deformation of the third connection zone, which allows the leakage protection wall to be lifted with the third connection zone as the starting point of the rise.

[0028]

In such an absorbent pant-shaped article, it is desirable that

the length of the third joint zone in the vertical direction was longer than the length of the second joint zone in the vertical direction.

[0029]

In such a pant-shaped absorbent article, by increasing the area extending in the vertical direction in which the leakage barrier can rise, it is possible to maximize the area in which the height of possible rise is limited to which the leak barrier can rise at the starting point of the rise. , which is located in the third connecting zone. Thus, leakage of secretions can be easily suppressed and the fit of the pant-shaped absorbent article can be improved when the wearer wears the pant-shaped absorbent article.

[0030]

In such an absorbent pant-shaped article, it is desirable

that the absorbent body includes an absorbent core that absorbs liquids, and

that the outer end portion of the sheet forming the leakage barrier in the leakage barrier is positioned lateral to the outside of the absorbent core, and

so that the third connection zone is located laterally between the absorbent core and the first connection zone.

[0031]

Since, in such an absorbent pant-shaped article, the third connection zone is located laterally between the absorbent core and the first connection zone, the third connection zone suppresses the outward movement of urine and the like laterally (towards the side flap) from the absorbent core. Accordingly, urine and the like do not easily leak into the side valve, and the possibility of causing discomfort to the wearer can be reduced.

[0032]

In such an absorbent pant-shaped article, it is desirable

that the absorbent body includes an absorbent core that absorbs liquids, and

so that at least a portion of the outer end portion of the leakage barrier sheet that forms the leakage barrier wall is located at a location in the lateral direction in which it overlaps the absorbent core, and is located on the non-skin side with respect to absorbent core, and

so that at least a portion of the third bonding zone is positioned laterally at a location where it overlaps the absorbent core and is positioned on the skin side of the absorbent core.

[0033]

Since, in such a pant-shaped absorbent article, the two laterally end portions of the absorbent core are closed by the leakage barrier wall, the leakage barrier wall suppresses the movement of urine and the like laterally outward (toward the side flap) from the absorbent core. Accordingly, urine and the like do not easily leak into the side valve, and the possibility of causing discomfort to the wearer can be reduced.

[0034]

In such an absorbent pant-shaped article, it is desirable that,

if we consider a straight line formed by the continuation of the line that connects

- a point at the lower end and laterally inner end of the third connection zone, and

- a point at the lower end and the laterally inner end of the second connection zone located in the front upper end of the absorbent body, then

-- the intersection point of the first bonding area and this straight line was located on the side back in the front-to-back direction with respect to the lower end of the absorbent body, in a state in which the absorbent body is unfolded.

[0035]

In such a pant-shaped absorbent article, on the back side in the front-to-back direction, there is a part (zone) in which the leakage protection wall can be raised to a maximum height without being affected by the second connection zone and the third connection zone. That is, the lifting height of the leakage protection wall is limited on the front side, and the lifting height of the leakage protection wall is large on the rear side. Thus, the leakage of secretions from the front side and the rear side can be suppressed.

[0036]

In such an absorbent pant-shaped article, it is desirable that

the pant-shaped absorbent article further comprised a front waist portion and a rear waist portion, and,

if we consider a straight line formed by the continuation of the line that connects

- a point at the lower end and laterally inner end of the third connection zone, and

- a point at the lower end and the laterally inner end of the second connection zone located in the front upper end of the absorbent body, then

-- the intersection point of the first bonding area and this straight line was located in the vertical direction lower than the lower end of the rear waist portion in the state in which the absorbent body is unfolded.

[0037]

In such a pant-shaped absorbent article, the leakage barrier wall is highly likely to rise to the maximum height in the area which is located in the vertical direction between the lower end of the absorbent body and the lower end of the back waist portion. Thus, the leak-proof wall can be raised to a maximum height near the excretory opening (anus) of the wearer, and it is possible to reduce the possibility of leakage of excretions (faeces).

[0038]

In such an absorbent pant-shaped article, it is desirable that

the vertically defined length of the second bond zone, which is located at the front upper end of the absorbent body, was less than the vertically defined length of the second bond zone, which is located at the rear upper end of the absorbent body.

[0039]

In such a pant-shaped absorbent article, the vertically defined length of the front second connection zone is small, and the location of the lower end of the front second connection zone is shifted upward. Therefore, the place where the leakage protection wall rises to the maximum height can be easily shifted down. Thus, when the wearer wears the pant-shaped absorbent article, the leg of the wearer will not be easily caught on the leak-proof wall, and it is possible to make the pant-shaped absorbent article easy to put on while suppressing leakage of secretions from the front side and the back side.

[0040]

In such an absorbent pant-shaped article, it is desirable

so that the third connecting zone includes

a front third bonding area which is located at the front upper end portion of the absorbent body, and

a rear third bonding zone which is located at the rear upper end portion of the absorbent body,

to

- the upper end of the front third connection zone extends in the vertical direction to the front upper end of the absorbent body, and

- the upper end of the rear third connection zone extends in the vertical direction to the rear upper end of the absorbent body.

[0041]

In such an absorbent pant-shaped article, the front third connection area and the back third connection area bridge the gap between the first connection area and the second connection area, and the upper end of the absorbent body and the leakage protection wall are connected. Thus, it is possible to suppress the passage of exudates through the gap between the first bonding area and the second bonding area outward from the upper end of the absorbent body.

[0042]

An absorbent article shaped like a pant and having a vertical direction, a lateral direction, and a front-to-back direction that intersect each other,

wherein these two leakage-proof walls are liftable towards the skin side of the wearer from the two sides of the absorbent body,

wherein, if the pant-shaped absorbent article is viewed from above in a state in which the waist opening is expanded from the natural state in the front-to-back direction and in the side direction,

- that part of each leak-proofing wall whose lifting height towards the skin side is the greatest is located on the back side in the front-to-back direction.

[0043]

In such a pant-shaped absorbent article, the lifting height of the leakage protection wall is increased in the rear region, and therefore, a large space (volume) in which feces can be held between the absorbent body and the wearer's body can be provided. In addition, the lifting height of the leakage protection wall is limited in the front region, and therefore, it is possible to reduce the distance between the absorbent body and the body of the wearer to enable efficient absorption of urine and to reduce the possibility of leakage of urine and the like.

[0044]

In such an absorbent pant-shaped article, it is desirable that

the first lift start point was inside in a lateral direction with respect to the second lift start point,

wherein the first starting point of the rise is the starting point from which each leak-proof wall rises at a first point which is located at least on the side front in the front-to-back direction with respect to the center in the front-to-back direction,

wherein the second lifting start position is the starting position from which the leak-proof wall is lifted at the second position, which is on the side rearward in the front-to-back direction with respect to the first position.

[0045]

In such a pant-shaped absorbent article, by allowing the leakage barrier wall to rise to a great height at the second position on the rear side, a large space can be formed in which feces can be held between the absorbent body and the body of the wearer. In addition, it is possible to suppress fecal leakage. By limiting the lifting height of the leakage protection wall at the first position on the front side, leakage of urine in the lateral direction can be easily suppressed and the gap between the absorbent body and the body can be reduced so that urine can be easily absorbed. Thus, it is possible to provide a pull-on disposable diaper that can easily suppress discharge leakage from the front side and back side.

[0046]

In such an absorbent pant-shaped article, it is desirable that

each of the two anti-leak walls was attached to the absorbent body through a first bonding zone, a second bonding zone, and a third bonding zone,

- wherein the first connecting zone is a zone provided in the outer in the lateral direction, the end part and extending in the vertical direction,

-- between the lower end of the second connection zone, which is provided in the front upper end of the absorbent body, and the lower end of the absorbent body, defined in the vertical direction, and

-- between the first connection zone and the second connection zone in the lateral direction.

[0047]

In such a pant-shaped absorbent article, it can be ensured that the lift height of that portion of the leakproof wall that begins to rise in the third bonding zone can be less than the lift height of that portion of the leakproof wall that begins to rise in the first bonding zone. Accordingly, the proper execution of the connecting zones enables more effective suppression of the leakage of secretions from the front side and the rear side.

[0048]

In such an absorbent pant-shaped article, it is desirable that

the first location was a location that overlaps the third connection area in the vertical direction.

Thus, it is possible to provide an absorbent article having a leak-proof wall that can more easily adhere to the wearer's body according to the size and the like of the wearer's body.

[0050]

In such an absorbent pant-shaped article, it is desirable that,

if we consider a straight line formed by the continuation of the line that connects

-- the intersection point of the first bonding area and this straight line was located on the side back in the front-to-back direction with respect to the lower end of the absorbent body, in a state in which the absorbent body is unfolded.

[0051]

In such a pant-shaped absorbent article, on the back side in the front-to-back direction, there is a part (zone) in which the leakage protection wall can be raised to a maximum height without being affected by the second connection zone and the third connection zone. That is, the lifting height of the leakage protection wall is limited on the front side, and the lifting height of the leakage protection wall is large on the rear side.

that the pant-shaped absorbent article further comprises a front waist portion and a rear waist portion, and

so that the lower end of the third connecting zone is located in the vertical direction lower than the lower end of the rear waist portion.

[0055]

In such a pant-shaped absorbent article, by allowing the leakage barrier wall to rise in the region below the rear waist portion, it is possible to form a portion having a higher maximum liftable height where the leakage barrier begins to rise in the first connection region, and the portion , having a small maximum lifting height, where the leakage protection wall begins to rise in the third connection zone. Thus, the leakage of secretions can be effectively suppressed.

[0056]

In such an absorbent pant-shaped article, it is desirable that

the lower end of the third bonding zone was located on the side front in a front-to-back direction with respect to the lower end of the absorbent body.

Accordingly, urine and the like do not easily leak into the side valve, and the possibility of causing discomfort to the wearer can be reduced.

[0070]

In such an absorbent pant-shaped article, it is desirable

that the absorbent body includes an absorbent core that absorbs liquids, and

that at least a portion of the outer end portion of the leakage barrier sheet, which forms the leakage barrier wall, is positioned in a position laterally in which it overlaps the absorbent core and is located on the non-skin side of the absorbent core, and

so that at least a portion of the third bonding zone is positioned laterally at a location where it overlaps the absorbent core and is positioned on the skin-facing side of the absorbent core.

[0071]

Since, in such a pant-shaped absorbent article, the two laterally end portions of the absorbent core are closed by the leakage barrier wall, the leakage barrier wall suppresses the movement of urine and the like laterally outward (toward the side flap) from the absorbent core. Accordingly, urine and the like do not easily leak into the side valve, and the possibility of causing discomfort to the wearer can be reduced.

[0072]

In such an absorbent pant-shaped article, it is desirable that

the vertically defined length of the second bond zone, which is located at the front upper end of the absorbent body, was less than the vertically defined length of the second bond zone, which is located at the rear upper end of the absorbent body.

[0073]

In such a pant-shaped absorbent article, the length defined in the vertical direction of the front second connection zone is small, and the location of the lower end of the front second connection zone is shifted upward. Therefore, the place where the leakage protection wall rises to the maximum height can be easily shifted down. Thus, when the wearer wears the pant-shaped absorbent article, the leg of the wearer will not be easily caught on the leak-proof wall, and it is possible to make the pant-shaped absorbent article that can be put on easily while suppressing the leakage of secretions from the front side and the back side.

[0074]

In such an absorbent pant-shaped article, it is desirable that

the third connecting zone included

a front third bonding area which is located at the front upper end portion of the absorbent body, and

a rear third bonding zone which is located at the rear upper end portion of the absorbent body,

to

- the upper end of the front third connection zone extends in the vertical direction to the front upper end of the absorbent body, and

- the upper end of the rear third connection zone extends in the vertical direction to the rear upper end of the absorbent body.

[0075]

In such a pant-shaped absorbent article, the front third connection area and the back third connection area bridge the gap between the first connection area and the second connection area, and the upper end of the absorbent body and the leakage protection wall are connected. Thus, it is possible to suppress the passage of exudates through the gap between the first bonding area and the second bonding area outward from the upper end of the absorbent body.

[0076]

=== Embodiment ===

The pull-on disposable baby diaper will be described as an example of an absorbent article according to the present embodiment. It should be noted that the absorbent article can be used not only as a pull-on disposable baby diaper, but also as an adult sanitary panty, panty liner or the like.

[0077]

<Configuration of the pull-on disposable diaper 1>

1 is a schematic perspective view of a pull-on disposable diaper 1 (hereinafter also referred to simply as "diaper 1"). 2 is a plan view of the diaper 1 in the unfolded and stretched state. 3 shows a plan view and a sectional view illustrating the configurations of the absorbent body 10 and the leakage barrier wall 50.

[0078]

In the pant-shaped state illustrated in FIG. 1, the diaper 1 has a vertical direction, a lateral direction, and a front-to-back direction that intersect with each other, and a waist opening BH and two leg openings LH are formed. With respect to the vertical direction, the waist opening BH side is referred to as the upper side and the crotch side is referred to as the lower side. As shown in the sectional view of FIG. 3, the direction in which the constituent members of the diaper 1 are stacked is referred to as the thickness direction, and that side in the thickness direction that comes into contact with the wearer's body (skin) is referred to as the side. , and the side in the thickness direction that does not come into contact with the wearer's body (skin) is referred to as the non-skin side.

[0079]

The "stretched state" of the diaper 1 refers to the state in which the entire diaper 1 (the whole article) is stretched (-o) so that the wrinkles formed therein are essentially no longer visible due to the stretching of the elastic elements of the diaper 1 (such as the elastic elements 17 for legs and thread-like elastic elements 23 and 33, described below). More specifically, the stretched state refers to a state in which the diaper 1 is stretched to such an extent that the dimensions of each of the constituent members (such as the absorbent body 10 and the waist portions 20 and 30 described below) of the diaper 1 match or become close to the dimensions of their as separate elements.

[0080]

The diaper 1 includes an absorbent body 10, a front waist portion 20, and a rear waist portion 30, which are three elements that are rectangular in plan view. The front waist portion 20 (front waist portion) comes into contact with the wearer's front body portion, and the rear waist portion 30 (rear waist portion) engages with the wearer's rear body portion.

[0081]

In the unfolded diaper 1 illustrated in FIG. 2, the front waist portion 20 and the rear waist portion 30 are positioned so that their longitudinal direction coincides with the lateral direction of the diaper 1. The portion of the absorbent body 10 corresponding to one end in the longitudinal direction ( the front end portion) is located at the center of the front waist portion 20 as defined in the side direction, and the portion of the absorbent body 10 corresponding to the other end in the longitudinal direction (the rear end portion) is located at the center of the back waist portion 30 as defined in the side direction.

[0082]

In the unfolded diaper 1 illustrated in FIG. 2, the absorbent body 10 is folded in half at a predetermined location FL in the longitudinal direction, with the longitudinal direction of the absorbent body 10 coinciding with the vertical direction of the diaper 1. The two side end portions of each the front waist portion 20 and the back waist portion 30 are connected to each other by using a joining method such as heat sealing or ultrasonic sealing, forming two connected zones 2. Thus, the diaper 1 is put into a pant-shaped state (see Fig. 1), wherein the diaper 1 has a waist opening BH and two leg openings LH.

[0083]

As illustrated in FIG. 3, the absorbent body 10 includes an absorbent body 11, a topsheet 12 that is located on the skin-facing side of the absorbent body 11, and a backsheet 13 that is located on the non-skin-facing side. to the skin, with respect to the absorbent body 11, and which serves as the outer member of the absorbent body 10. Two leakage protection walls 50 are provided on two sides of the absorbent body 11.

[0084]

The absorbent body 11 includes an absorbent core 11A that absorbs and retains discharged fluids such as urine, and a liquid-permeable core wrap sheet 11B that covers the absorbent core 11A. For example, the absorbent core 11A is an element formed by shaping liquid-absorbent fibers (cellulose fibers including super absorbent polymer (SAP), etc.). The core wrapping sheet 11B is, for example, tissue paper.

[0085]

The absorbent core 11A according to the present embodiment has a narrow portion 11AC between the front end portion and the rear end portion defined in the longitudinal direction. The narrow portion 11AC has a shorter length in the lateral direction (width direction). The narrow portion 11AC is to be placed between the legs of the wearer when the wearer wears the diaper 1. Because the narrow portion 11AC has a smaller length (width) in the lateral direction, the absorbent core 11A can easily fit the wearer's crotch.

[0086]

The top sheet 12 is a sheet-like element that covers the absorbent body 11 from the side facing the skin and is formed, for example, from a liquid-pervious, non-woven material, which has a larger dimension in the plane than the absorbent body 11.

[0087]

The back sheet 13 is a sheet-like member that covers the absorbent body 11 on the non-skin side, and is a sheet member that is larger in plane than the absorbent body 11. The back sheet 13 is a two-layer sheet member that consists of the backsheet forming film 13a and the outer sheet 13b, wherein the backsheet forming film 13a is, for example, a liquid impervious film of polyethylene, polypropylene or the like, and the outer sheet 13b is a non-woven fabric or the like. a material provided on that side of the backsheet-forming film 13a that is not facing the skin.

[0088]

The outer sheet 13b has protrusions 13bf that protrude to a large extent laterally outward from both ends 11es of the absorbent body 11. The protrusions 13bf are folded inward in the lateral direction and towards the skin-facing side, defined in the thickness direction, on both the ends 10es of the absorbent body 10 defined laterally. Here, the folded protruding portions 13bf are superimposed on themselves in the thickness direction, and thus the side flaps SF are formed. In each of the side flaps SF, a plurality of leg elastics 17 such as elastic veins are fixed between the protrusions 13bf, which are folded over and superimposed on themselves in the thickness direction, in a state in which the leg elastics 17 are stretched in the vertical direction ( longitudinal direction), and are located at predetermined distances from each other in the lateral direction. Thus, the side flaps SF are stretchable in the vertical direction (longitudinal direction of the absorbent body 10). Since a plurality of leg elastics 17 are arranged in the transverse direction, the side flaps SF each maintaining a flat state are shaped such that they protrude laterally outward from the two sides of the absorbent body 10, as illustrated in FIG. . Accordingly, when the wearer wears the diaper 1, the side flaps SF can easily fit along the thigh surfaces of the wearer. Thus, leakage of exudates or the like from the leg openings LH can be easily suppressed.

[0089]

The leakage barrier walls 50 are formed from flexible sheet members and are provided on two sides of the absorbent body 11 and in the thickness direction on the skin-facing side of the absorbent body 11. When the wearer wears the diaper 1, the leakage barrier walls 50 are raised from the two sides of the absorbent body 11 toward the skin side of the wearer, which suppresses leakage of exudates outward from the absorbent body 10. Features of the leakage-proof walls 50 will be described below.

[0090]

The front waist portion 20 (rear waist portion 30) includes a sheet 21 (31) forming an inner layer, a sheet 22 (32) which forms an outer layer and superimposed on a sheet 21 (31) forming an inner layer, and a plurality of thread-like elastic elements 23 (33).

[0091]

The sheet 22 (32) forming the outer layer is located on the non-skin side of the sheet 21 (31) forming the inner layer. The core sheet 21 (31) and the outer layer sheet 22 (32) are located on the non-skin side of the absorbent body 10. Each of the core sheets 21 and 31 and the sheets 22 and 32 forming the outer layer is a non-stretch sheet that does not have a significant ability to stretch in the lateral direction of the diaper 1. As each of the sheets 21 and 31 forming the inner layer and the sheets 22 and 32 forming the outer layer, there may be SMS structure nonwoven fabric (spunbonded layer - meltblown layer - spunbond layer structure), spunbonded nonwoven fabric, breathable nonwoven fabric, plastic sheet, perforated plastic sheet or laminate from these sheets.

[0092]

A plurality of thread-like elastic members 23 (33) are fixed between the sheet 21 (31) constituting the inner layer and the sheet 22 (32) constituting the outer layer in a state in which the thread-like elastic members 23 (33) are arranged side by side in a vertical direction and extended laterally. Thus, the front waist portion 20 and the rear waist portion 30 can be stretched and retracted laterally and fit against the wearer's waist. Each of the thread-like elastic members 23 and 33 is, for example, a thread-like elastic member such as rubber or spandex.

[0093]

In the back waist portion 30 according to the present embodiment, thread-like elastic members 33 are arranged from the upper end portion to the lower end portion. On the other hand, at the upper end portion of the front waist portion 20, the thread-like elastic members 23 are not provided, and instead a stretch sheet 24 is provided, which is stretched and contracted laterally. By placing the stretch sheet 24 instead of the thread-like elastic members 23 at the upper end of the front waist portion 20, the upper end of the front waist portion 20 can easily and tightly come into surface contact with the body (skin) of the wearer. Thus, a situation is prevented in which the front waist portion 20 becomes locally tight and the stretch/contract member is unlikely to leave a mark on the wearer's skin. In particular, since an infant who is expected to wear the diaper 1 generally has a protruding belly, it is possible to reduce the likelihood that the infant will experience discomfort while wearing the diaper 1 by suppressing the local tightening around the abdomen when using such a front waistband. part 20, as in this embodiment.

[0094]

<Leak proof wall 50>

Next, the details of the configuration and operation of each of the leakage barrier walls 50 will be described. The leak-proof wall 50 has a sheet 51 forming a leak-proof wall and a plurality of elastic members 52 of the leak-proof wall. The sheet 51 forming the anti-leakage wall is a rectangular flexible sheet member and is formed of, for example, a non-woven fabric or the like. The leakage-proof wall sheet 51 according to the present embodiment is disposed on each side end portion of the absorbent body 10 so that it extends in the vertical direction (longitudinal direction of the absorbent body 10). As illustrated in FIG. 3, the leak-proof wall sheet 51 is folded outward in the side direction at the side-inside end 50is. A plurality of leakproof wall elastic members 52 such as elastic veins are fixed between the leakproof wall sheets 51 and superimposed on each other in the thickness direction, in a state in which the leakproof wall elastic members 52 are stretched in the vertical direction and arranged at predetermined distances from each other in the lateral direction. Thus, the leakage protection wall 50 has extensibility in the vertical direction (longitudinal direction). When the wearer wears the diaper 1, due to extensibility, that end portion (inner end 50is) of the leakage protection wall 50 which is laterally inner rises towards the skin side of the wearer.

[0095]

As shown by hatching in FIG. 3, the leakage barrier 50 is attached to the absorbent body 10 by a first bonding region 55, a second bonding region 56, and a third bonding region 57, which are formed from a bonding material such as a hot melt adhesive.

[0096]

The first connection zone 55 is a long narrow zone extending in the vertical direction (longitudinal direction of the absorbent body 10) in the lateral outer end portion of the leakage barrier wall 50. The first connection zone 55 connects the leakage barrier wall 50 to the skin-facing surface of the side flap SF. When the wearer wears the diaper 1, at least a portion of that area of the leak-proof wall 50 which is laterally inner with respect to the first connection area 55 rises towards the skin side from the original location, which is the end of the first connection area 55, inner sideways. That is, the first connection zone 55 is a zone that serves as a starting point for the rise of the leakage protection wall 50.

[0097]

A second connection zone 56 is provided at each of the front upper end portion and the rear upper end portion of the absorbent body 10 and inwardly laterally with respect to the first joint zone 55. The second joint zone 56 connects two parts of the leakage barrier wall 50 which are end in the longitudinal direction, with the surface of the absorbent body 11 (top sheet 12) facing the skin. In the following description, the second bonding area 56 provided at the front upper end portion of the absorbent body 10 is also referred to as "the front second bonding area 56f", and the second bonding area 56 provided at the rear upper end portion of the absorbent body 10 is also referred to as "rear second connection zone 56b". The two parts of the leakage wall 50, which are longitudinally end, are connected by the second connection zones 56f and 56b, which ensures that the leakage wall 50 is fixed so that the leakage wall 50 cannot rise in these zones. That is, the leakage protection wall 50 is liftable in the area located in the longitudinal direction between the front second connection area 56f and the rear second connection area 56b.

[0098]

The third connection zone 57 is provided at least between the lower end 56fed (rear end in the front-to-back direction) of the front second connection zone 56f and the lower end of the absorbent body 10 defined in the vertical direction (the position FL where the absorbent body 10 is folded twice in the longitudinal direction) and between the first connection area 55 and the second connection area 56 in the lateral direction. The third connection zone 57 is provided internally in a lateral direction with respect to the first connection zone 55. Accordingly, at the location of the third connection zone 57, the rise of the leakage protection wall 50 does not start in the first connection zone 55, but in the third connection zone 57. That is, in the zone in which the third connection zone 57 is provided in the vertical direction (longitudinal direction), the height of possible lifting to which the leakage protection wall 50 can be raised will be smaller compared to the zone in which the third connection zone 57 is not provided (see FIG. .6 and 7 described below).

[0099]

4 is a schematic plan view illustrating the relationship between the location of the connecting zones 55, 56 and 57 and the height of the possible rise to which the leakage protection wall 50 can rise. Fig. 5 is a schematic sectional view taken along line A-A in Fig. 4. Fig. 6 is a schematic sectional view taken along line B-B in Fig. 4. Fig. 7 is a schematic sectional view taken along line C-C in Fig. 4. Fig.4 illustrates the diaper 1 in the unfolded and stretched state, as in the case of Fig.2.

[0100]

First, as illustrated in FIG. 5, in the area in which the second connection area 56 (56f, 56b) is formed in the vertical direction (longitudinal direction of the absorbent body 10) inner in the side direction, the end portion (inner end 50is) of protecting the leakage protection wall 50 is attached to the absorbent body 10, and therefore the leakage protection wall 50 cannot be raised.

[0101]

Further, as illustrated in FIG. 6, at a certain location (indicated as the first location) in the area in which the third connection area 57 is provided at least on the front side with respect to the center in the front-to-back direction, the inner end 50is of the leakage protection The wall 50 rises towards the skin side at the first lift start point, which is the inner end 57is of the third connection zone 57. Here, the maximum lift height to which the leak-proof wall 50 can rise is referred to as the "first lift height H57". The first lift height H57 is the distance from the first lift start position to the raised distal end of the leakage barrier wall 50. That is, in the lateral direction in FIG. wall 50 protecting against leakage.

[0102]

As illustrated in FIG. 7, at a certain location (indicated as the second location) in the area in which the third connection area 57 is not provided and the first connection area 55 is provided at the rear side of the first location, the inner end 50is of the leakage protection wall 50 rises towards the skin side at the second lift start location, which is the inner end 55is of the first connection zone 55. Here, the maximum lift height to which the leak-proof wall 50 can rise is referred to as the “second lift height H55”. The second lift height H55 is the distance from the second lift start point to the raised distal end of the leak proof wall 50. That is, in the lateral direction in FIG. 4, the second lift height H55 is the distance between the inner end 55is of the first connection zone 55 and the inner end 50is of the leak proof wall 50.

[0103]

[0104]

As can be clearly seen in FIG. 4, the first lift start position is inwardly lateral to the second lift start position. Accordingly, the lateral distance between the inner end 57is of the third connection zone 57 and the inner end 50is of the leakage barrier wall 50 is less than the lateral distance between the inner end 55is of the first connection zone 55 and the inner end 50is of the leakage barrier 50. Thus, in the diaper 1, it can be ensured that the liftable height (first lift height H57) to which the leakage protection wall 50 can be raised at the first front side in the forward-backward direction is smaller than the liftable height ( second lift height H55) up to which the leak-proof wall 50 can be raised at a second location rearward of the first location.

[0105]

8A and 8B illustrate the inner side of the diaper 1 viewed from above in a state in which the waist opening BH of the diaper 1 is expanded in the front-to-back direction (and laterally). Fig. 8A illustrates a state in which the user has inserted their hands from below into the two leg holes LH of the diaper 1 in the natural state and expanded the waist hole BH in the front-to-back direction and laterally. Fig. 8B illustrates a state in which the user has inserted his or her hands from above into the waist opening BH of the diaper 1 in the natural state and expanded the waist opening BH in the front-to-back direction and laterally. The "natural state" of the diaper 1 refers to the state in which the diaper 1 has remained intact for a predetermined time. For example, in the case of the pant-shaped diaper 1, the wearer stretches the waist portions 20 and 30 laterally outward to cause each of the waist portions 20 and 30 and the absorbent body 10 to be "stretched". Thereafter, the stretched state is maintained for 15 seconds, then the tension of the diaper 1 is released and the diaper 1 is placed on a flat surface such as a desktop surface. The natural state is the state in which the diaper 1 finds itself after being placed on a flat surface and remaining there for 5 minutes.

[0106]

When the wearer wears the diaper 1 and the waist opening BH is expanded from the natural state in the front-to-back direction and laterally, the leakproof wall elastic 52 is stretched, and the contraction force generated by the leakproof wall elastic 52 will be applied to the inner ends 50is walls 50 protecting against leakage. With this, the leakage barrier walls 50 will rise towards the skin side of the wearer, and the inner ends 50is of the leakage barrier walls 50 can easily come into contact with the skin (groin or the like) of the wearer. Meanwhile, as illustrated in FIGS. 8A and 8B, the lift-able height (H57) to which the leak-proof walls 50 can be lifted from the forward-backward side of the diaper 1 is small, and the lift-able height (H55) , up to which the leakage-proof walls 50 can be raised from the back side in the front-to-back direction, is large. In other words, the portions (H55) in which the leakage protection walls 50 rise to the maximum height towards the skin side are located on the back side in the front-to-back direction.

[0107]

The infant who is the main wearer of the diaper 1 usually sleeps on his back. Therefore, when the infant excretes feces, the absorbent body 10 is unlikely to absorb the feces, and the feces tend to accumulate on the rear side (rear). Thus, by allowing the leakage protection wall 50 to be raised to a higher height in the back region (at the second location) of the diaper 1, a large space (volume) in which feces can be held in the diaper 1 between the absorbent body 10 and the infant's body can be provided, and suppress leakage of feces to the outside of the absorbent body 10. On the other hand, since the infant has a small body size, if the lifting height of the leakage protection wall 50 is too large on the front side, a large gap is formed between the absorbent body 10 and the infant's body, which makes it difficult to absorb urine. By limiting the lifting height of the leakage protection wall 50 in the front region (first place) of the diaper 1, the distance between the absorbent body 10 and the body of the wearer (infant) can be reduced, which enables efficient absorption of urine and reduces the possibility of leakage of urine and the like in the lateral direction. . Thus, it is possible to provide a pull-on disposable diaper 1 which can easily absorb urine from the front side and can easily suppress fecal leakage from the back side. In addition, by changing the position and length of the joint areas, the lifting height of the leakage protection wall 50 can be freely adjusted and the fit of the diaper 1 can be improved according to the wearer's body size and gender.

[0108]

The actual lifting height of the leakage protection wall 50 differs according to the location in the vertical direction (forward-backward direction). As shown in FIG. rise) is expected to be small in the upper zone in the vertical direction, and large in the zone lower in the vertical direction. In the region upper in the vertical direction, the leakage barrier 50 is fixed by the front second connecting region 56f so that the leakage barrier 50 cannot be lifted (see FIG. 5). Therefore, due to the effect of the front second connection zone 56f, the lift height of the leakage barrier wall 50 in this zone will be less than the first lift height H57, which is the maximum lift height to which the leakage barrier 50 can rise. vertical direction, the impact of the front second connection area 56f is negligible, and the leakage barrier wall 50 can easily rise to the first lifting height H57, which is the maximum lifting height that the leakage barrier wall 50 can rise to. That is, the actual lifting height of the leakage barrier against leakage, the wall 50 increases towards the side lower in the vertical direction.

[0109]

Similarly, as shown in FIG. 4, the actual liftable height to which the leak-proof wall 50 can be raised in the area (second location) in which the first connection area 55 is the starting point of the rise (the second starting point lift) is small in the area, upper in the vertical direction, next to the third connecting zone 57 and large in the area, lower in the vertical direction and remote from the third connecting zone 57.

[0110]

Such a change in the lifting height of the leakage barrier wall 50 can be explained as follows. That is, a line that connects a point (point P in FIG. 4) and a point (point Q in FIG. 4) is defined as a straight line SL (shown by a dotted line in FIG. 4), and point P is a point located inside laterally in the front second connection area 56f and at the bottom end in the vertical direction, and the point (point Q in Fig. 4) is a point located laterally inside in the third connection area 57 and at the bottom end in the vertical direction direction. In this case, the leakage protection wall 50 can be easily raised in the area laterally inner with respect to the straight line SL. This is because, in the area laterally inner with respect to the straight line SL, it is difficult for the second connection area 56 and the third connection area 57 to affect the leakage protection wall 50. Accordingly, the distance H50X in the lateral direction between the straight line SL and the inner the end 50is of the leakage barrier wall 50 which is shown in FIG. 4 can be considered as the actual lift height of the leakage barrier wall 50.

[0111]

The actual lifting height H50X of the leakage barrier wall 50 gradually increases from the vertically upper side to the vertically lower side, and becomes maximum at the intersection point (point R in FIG. 4) of the straight line SL and the end 55is of the first connection zone 55, inner sideways. As can be clearly seen from Fig. 4, the point R is located on the side back in the front-to-back direction with respect to the lower end (FL) of the absorbent body 10 (on the back side with respect to the center of the absorbent body 10, defined in the longitudinal direction ). Accordingly, as described above with reference to FIG. 8, it is clear that the portion in which the leak-proof wall 50 rises to the maximum height is on the front-back rear side. In the diaper 1, the portion in which the leak-proof wall 50 actually rises to the maximum height (the second lift-up height H55) is an area that includes the point R and which has a predetermined length in the vertical direction, and the leak-proof wall 50 optionally rises to a high altitude locally at point R.

[0112]

The point R of intersection of the straight line SL and the laterally inner end 55is of the front joint area 55 is vertically lower than the lower end 30ed of the rear waist portion 30 (in front of the lower end 30ed of the rear waist portion 30 in the longitudinal direction figure 4). Accordingly, the leakage barrier 50 rises to a maximum height in the area between the position FL of the lower end of the absorbent body 10 and the vertically lower end 30ed of the rear waist portion 30. Thus, when the wearer wears the diaper 1, the leak-proof wall 50 can rise to a maximum height near the excretory opening (anus) of the wearer, and the diaper 1 can easily contain excretions (feces).

[0113]

As illustrated in FIGS. 4 to 7, in the diaper 1, the outer end part of the leakage barrier wall 50 is located laterally outside the absorbent core 11A and is connected to the skin side flap surface SF through the first connection zone 55. When such a configuration, for example, when the wearer exudes a large amount of urine that the absorbent core 11A cannot absorb, there is a risk of urine leaking into the side valve SF, causing discomfort to the wearer. In the illustrated embodiment, the third connection zone 57 is located outside the absorbent core 11A and laterally inside the first connection zone 55 (ie, between the absorbent core 11A and the first connection zone 55). Accordingly, the third connecting area 57 can suppress the movement of urine and the like to the side flap SF from the absorbent core 11A, and it is possible to reduce the possibility of causing discomfort to the wearer.

[0114]

In the diaper 1 according to the present embodiment, the lifting height of the leakage protection wall 50 is adjusted by appropriately adjusting the area in which the third connection area 57 and the second connection area 56 are provided in the vertical direction.

[0115]

As illustrated in FIG. 4, the lower end 57ed of the third connection zone 57 is positioned lower in the vertical direction than the lower end 30ed of the rear waist portion 30. Thus, in the zone in which no waist tightening force is applied by the rear waist portion 30 when the wearer wears the diaper 1, the leakage protection wall 50 can easily rise towards the skin side. That is, the leak-proof wall 50 can be raised in a predetermined area below the rear waist portion 30. In the raised leak-proof wall 50, a part is formed that has a large maximum lifting height H55 and in which the leak-proof wall 50 can be raised from the first of the connection area 55, and a part that has a small maximum lifting possible height H57 and in which the leakage protection wall 50 can be raised from the third connection area 57. Accordingly, as described above, it is possible to suppress leakage of urine from the forward-backward direction side. , and suppress the leakage of feces from the rear area.

[0116]

In addition, it is preferable that the lower end 57ed of the third connection zone 57 be located on the side front in the front-to-back direction with respect to the lower end (FL) of the absorbent body 10. This provides an increase in the zone in which the leakage protection wall 50 can be raised to the maximum possible lifting height H55 from the starting point of the lifting, which is in the first connection zone 55. That is, it is possible to increase the zone in which the leakage protection wall 50 is raised to a high height when the wearer wears the diaper 1. Thus, it is possible to increase a space (volume) in which feces can be held, and leakage of feces outward from the absorbent body 10 can be more easily suppressed.

[0117]

The upper end 57eu of the third connection zone 57 is located in the vertical direction higher than the lower end 20ed of the front waist portion 20. Thus, on the front side of the diaper 1, in a large portion of the zone in which no force is applied causing waist tightening and created by the front waist portion 20 , it is possible to make the leakage barrier wall 50 rise toward the skin side from the starting point of the rise, which is located in the third connection zone 57. That is, it is possible to increase the area in which the leak barrier 50 can rise while limiting the rise height. Thus, leakage of urine and the like in the side direction from the front side of the diaper 1 can be effectively suppressed.

[0118]

The upper end 57eu of the third joint zone 57 is located in the vertical direction higher than the lower end 56fed of the front second joint zone 56f. Thus, it is possible to maximize the area that is between the lower end 56fed of the front second connection area 56f and the bottom end 57ed of the third connection area 57 and in which the leakage protection wall 50 can rise towards the skin side from the starting point of the rise, which is in the third connection zone 57. That is, from the front side of the diaper 1, it is possible to ensure that the leakage barrier wall 50 rises over a larger area while limiting the lifting height of the leakage barrier wall 50 so that the height does not become excessively large, which can more effectively suppress urine leakage. and the like.

[0119]

In addition, the upper end 57eu of the third joint area 57 is located in the vertical direction lower than the upper end 56feu of the front second joint area 56f. In the area in which the third connection area 57 and the front second connection area 56f overlap in the vertical direction, the leakage protection wall 50 cannot be raised due to the second connection area 56f (see FIG. 5). That is, in the overlap zone, the maximum liftable height that the leakproof wall 50 can rise to is essentially zero, and the third connecting area 57 does not perform the function of adjusting the lift height of the leakproof wall 50. Therefore, by reducing the portion of the third bonding area 57 that overlaps the front second bonding area 56f in the vertical direction, it is possible to reduce the amount of adhesive that forms the third bonding area 57 and reduce that part of the absorbent body 10 that has a hard texture due to the third of the bonding area 57. Thus, it is possible to reduce the cost without impairing the function of the leakage protection wall 50, and obtain the diaper 1 with good texture.

[0120]

The lower end 57ed of the third bonding zone 57 is located in the vertical direction higher than the taper start point (point S in FIG. 4) of the narrow portion 11AC of the absorbent body 11 (absorbent core 11A). That is, the lower end 57ed of the third connecting zone 57 is located higher than the narrow part 11AC.

With such a configuration illustrated in FIG. 4, the distance in the lateral direction between the third connection zone 57 and the absorbent core 11A can be reduced. The absorbent body 11 (absorbent core 11A), in which (th) liquid absorbent materials such as liquid absorbent fibers are stacked, has a high rigidity compared to other parts (for example, leakage protection wall 50) . Accordingly, by reducing the distance between the third bonding region 57 and the absorbent core 11A, the occurrence of stress and deformation of the third bonding region 57 can be reduced. 57.

[0121]

The length of the third connection zone 57 in the vertical direction is greater than the length of the second connection zone 56 in the vertical direction. By reducing the length of the second connection zone 56, it is possible to increase the zone extending in the vertical direction in which the leakage protection wall 50 can be raised. By providing a longer length of the third connection zone 57 compared to the length of the second connection zone 56, it is possible to increase the zone in which the height of the possible rise is limited, to which the leakage protection wall 50 can rise at the start of the rise, which is located in the third connection zone 57 ( provides a lower height H57 compared to the height H55 in figure 4). Thus, the entire diaper 1 can more easily suppress leakage of secretions. In addition, since the lifting height of the leakage protection wall 50 is suitably adjusted, it is possible to improve the fit of the diaper 1 when the wearer wears the diaper 1.

[0122]

<Modifications of anti-leakage wall 50>

(First modification)

The leakage protection wall 50 of the diaper 1 may be modified as follows. Figa-9C illustrate the wall 50, protecting against leakage, in accordance with the first modification. FIGS. 9A-9C are schematic sectional views of the absorbent body 10 according to the first modification, which correspond respectively to FIGS. 5-7.

[0123]

In the leakage protection wall 50 according to the first modification, each sidewise outer end portion of the leakage protection wall sheet 51 is laterally folded inwards and located under the absorbent body 11 (on the non-skin side of the absorbent body 11). The first connection zone 55 is provided in the thickness direction between the absorbent body 11 and the backsheet 13 (side flap SF). The arrangement of the connecting zones 55-57 in the vertical direction is respectively the same as in the embodiment described above (see FIG. 3). Otherwise, the configuration of the diaper 1 is the same as in the embodiment described above.

[0124]

With such a configuration, it is also possible to adjust the lifting height of the leakage barrier wall 50 accordingly. cannot rise (see Fig. 9A). In the area extending in the front-to-back direction (vertical direction) in which the second connection area 56 is not provided and the third connection area 57 is provided (first place), the leak-proof wall 50 can rise towards the skin side at the starting point of the rise ( the first lift start point), which is located in the third connection zone 57 (see FIG. 9B). At the same time, the leakage protection wall 50 can be raised to the first elevation height H57. In the second zone, located on the side rearward in the front-back direction with respect to the first zone, the leakage protection wall 50 can rise towards the side of the skin along the laterally defined, each end 11es of the absorbent body 11. That is, the leakage protection the wall 50 is designed to be lifted towards the skin side at the laterally outward end 11es of the absorbent body 11 which is at the lift start point (the second lift start position) (see FIG. 9C). In this case, the leakage protection wall 50 can be raised up to the second elevation height H55. More specifically, the second lift start point of the leakage barrier wall 50 and the end 11es of the absorbent body 11 may be slightly offset from each other in the lateral direction (see FIG. 9C). However, in this case, it is assumed that such a shift does not occur.

[0125]

As illustrated in FIGS. 9A-9C, the third connection zone 57, which serves as the first lift start point of the leakage barrier wall 50, is disposed inwardly of the absorbent body 11 end 11es, which serves as the second lift start position. Thus, the liftable height (first lift height H57) to which the leakage protection wall 50 can be lifted at the first location on the forward-backward side will be smaller than the liftable height (second lift height H55) up to which the leakage barrier 50 can rise at the second location behind the first location. Accordingly, also in the case of the first modification, urine can be easily absorbed from the front side and fecal leakage from the rear side can be easily suppressed.

[0126]

In the first modification, the laterally outer end portion of the leakproof wall sheet 51 is folded toward the non-skin side with respect to the absorbent core 11A, and at least a portion of the outer end portion is disposed at a location in the laterally direction in which it overlaps the absorbent core 11A (see FIGS. 9A-9C). On the skin-facing side of the absorbent core 11A, a portion of the third bonding zone 57 is located at a location where it overlaps the absorbent core 11A (see FIG. 9A). That is, the leakage protection wall 50 covers each side of the absorbent core 11A. With such a configuration, for example, even when the wearer exudes a large amount of urine that the absorbent core 11A cannot absorb, it is possible to suppress the movement of urine and the like from the absorbent core 11A to the side valve SF. Accordingly, the side flap SF is unlikely to become wet, and it is possible to reduce the possibility of causing discomfort to the wearer.

[0127]

(Second modification)

As a second modification, the length of the front second connection zone 56f in the vertical direction may be less than the length of the rear second connection zone 56b in the vertical direction. For example, as shown in FIG. 4, when the vertical length of the front second connecting region 56f is shortened and the position of the lower end 56fed (point P in FIG. direction becomes sharp, and the point of intersection (point R in FIG. 4) of the straight line SL and the end 55is of the first joint zone 55, inner in the lateral direction, is shifted downward in the vertical direction (backward in the longitudinal direction). That is, the place where the leak-proof wall 50 rises to the maximum height is moved further back.

[0128]

In this case, when the wearer's (infant) leg is inserted through the leg hole LH to put on the diaper 1 on the wearer, the wearer's leg is less likely to be caught on the raised leak-proof wall 50. Accordingly, the second modification will make it easier to put on/wear the diaper 1 Thus, it is possible to provide the diaper 1 which can be put on easily while suppressing the leakage of secretions from the front side and back side.

[0129]

(Third modification)

In the third modification, a third connection zone 57 is further provided at the rear upper end portion of the absorbent body 10. FIG. 10 is a schematic plan view illustrating the connection zones according to the third modification. The leakage barrier wall 50 according to the third modification is attached to the absorbent body not only through the first bonding area 55 and the second bonding area 56, but also through the front third bonding area 57f located at the front upper end portion of the absorbent body 10 and the rear third a bonding zone 57b located at the rear upper end portion of the absorbent body 10.

[0130]

The front third connection area 57f has substantially the same configuration as the configuration of the third connection area 57 described above, and is a connection area that serves as the first starting point for the uplift of the leakage barrier wall 50. In this modification, the upper end 57feu of the front third the connecting zone 57f extends to the front upper end 10f of the absorbent body 10.

[0131]

The rear third joint area 57b is located at the same location in the lateral direction as the front third joint area 57f. The upper end 57beu of the rear third bond zone 57b extends vertically to the rear upper end 10eb of the absorbent body 10, and the lower end 57bed of the rear third bond zone 57b is located vertically higher than the lower end 56bed of the rear second bond zone 56b. As described above, in the area in which the rear second connection area 56b is formed, the leakage protection wall 50 is fixed so that the leakage protection wall 50 cannot be raised. Accordingly, the rear third connection area 57b, which overlaps the rear second connection area 56b in the vertical direction, does not serve as a base portion for lifting the leakproof wall 50. That is, the rear third connecting area 57b does not affect the lifting of the leakproof wall 50.

[0132]

On the other hand, since in the third modification, the third connecting areas 57f and 57b are provided up to the upper ends of the absorbent body 10 defined in the vertical direction, leakage of urine and the like can be easily suppressed. For example, in the example illustrated in FIG. 3, a bonding area laterally between the first bonding area 55 and the second bonding area 56 is not provided at the rear upper end of the absorbent body 10, and a gap is formed. Therefore, there is a risk of the discharge passing through the gap and leaking outward from the absorbent body 10. In particular, since the infant who wears the diaper 1 usually sleeps on his back, there is a tendency for the discharge to pass through the rear upper end portion of the absorbent body 10. 10 and the exudates may leak out. On the contrary, in the third modification, the third bonding areas 57f and 57b bridge the gap between the first bonding area 55 and the second bonding area 56, and the upper ends 10ef and 10eb of the absorbent body 10 are connected. Accordingly, the passage of exudates through the gap and outflow from the upper end of the absorbent body are easily suppressed.

[0134]

In the embodiment described above, the stretch sheet 24 is located at the upper end portion of the front waist portion 20. However, the configuration of the diaper 1 is not limited to this. For example, the stretch sheet 24 may be located anywhere in the vertical direction in the front waist portion 20.
