JP 2016-93482 A

The non-compressed region where the grid compressed portion is not provided has low rigidity of the absorbent body. Therefore, in the uncompressed region, the absorbent body is easily deformed, and the absorbent body is easily fitted to the wearer's body. However, there is a possibility that the absorbent body will be easily twisted and the absorbent area cannot be ensured.

Since the rigidity of the absorbent body is increased in the region where the lattice compression part is provided, the absorbent body is less likely to be twisted. However, by providing the lattice compression part, it becomes difficult for the absorber to fit the wearer's body. On the other hand, in order for the absorbent body to easily fit the wearer's body, for example, when one grid is provided with a large lattice compression part, the absorbent body is easily twisted and the absorbent area is sufficiently secured. There is a possibility that it will not be possible.

Therefore, there is a demand for an absorbent article that is capable of suppressing the twisting of the absorbent body and fitting the absorbent body to the wearer's body while maintaining the diffusibility of the excrement on the absorbent body. there is

(1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.

The absorbent article according to one aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, a thickness direction, a front side region, a rear side region, and the front side region and the rear side region in the front-rear direction. It has a sandwiched crotch region and an absorbent body arranged at least in the crotch region. The absorber is provided with a compressed portion that is compressed in the thickness direction. The pressing section has a first pressing section having a grid pattern in plan view of the absorber, and a second pressing section having a pattern different from the grid pattern in plan view of the absorber.

Thereby, the rigidity of the absorbent body can be changed between the region where the first pressing portion is provided and the region where the second pressing portion is provided. Therefore, since the deformation of the absorbent body can be controlled, it is possible to provide the second pressing part in addition to the first pressing part while maintaining the diffusibility of the excrement on the absorbent body by the first pressing part. , the suppression of twisting of the absorbent body and the fitting property of the absorbent body to the wearer's body can be compatible.

According to a preferred aspect, in a plan view of the absorbent body, the area occupied by the second pressing portion per unit area may be larger than the area occupied by the first pressing portion per unit area.

Thereby, since the rigidity of the area|region in which the 2nd pressing part is provided becomes higher than the rigidity of the area|region in which the 1st pressing part is provided, deformation|transformation of an absorber can be suppressed.

According to a preferred aspect, the second pressing part may be provided in the crotch region.

In the crotch region, the absorber is easily deformed in the width direction by being sandwiched between the wearer's legs. Therefore, by providing the second compressed portion in the crotch region, it is possible to suppress the deformation of the absorber due to being pinched by the wearer's legs.

According to a preferred aspect, the crotch region may have a rear crotch region located on the rear side of the center of the absorbent article in the front-rear direction. The second compression part may be provided in the rear crotch region.

By providing the second pressing portion in the rear crotch region, the rigidity of the absorbent body in the rear crotch region can be increased. This makes it difficult for the absorbent body to enter the groove of the buttocks (gluteal cleft), and a space for containing excrement (stool) can be secured.

According to a preferred aspect, the second pressing portion may be provided at a position separated from the first pressing portion in plan view of the absorber.

Thereby, compared with the case where the 1st pressing part and the 2nd pressing part are provided continuously, the force applied to one of the 1st pressing part and the 2nd pressing part becomes difficult to be transmitted to the other. . Therefore, the first pressing section and the second pressing section are less likely to be affected by each other, and the respective functions of the first pressing section and the second pressing section can be exhibited.

According to a preferred aspect, in a plan view of the absorbent body, the separation distance in the front-rear direction between the first pressing portion and the second pressing portion is the same as the front and rear of one lattice formed by the first pressing portion. It may be longer than the length in the direction.

As a result, compared to the case where the separation distance between the first pressing part and the second pressing part is shorter than the length of one grid of the first pressing material, one of the first pressing part and the second pressing part It becomes even more difficult for the applied force to be transmitted to the other side. Therefore, each function of a 1st pressing part and a 2nd pressing part can be exhibited further.

According to a preferred aspect, the first compressing portion includes a front lattice compressing portion provided on the front side of the center of the absorbent article in the front-rear direction, and a front lattice pressing portion provided on the rear side of the center of the absorbent article in the front-rear direction. and a post grate squeeze. In a plan view of the absorbent body, the area per unit area occupied by the rear lattice compression part may be larger than the area per unit area occupied by the front lattice compression part.

As a result, the region where the rear grid compression portion is provided has high rigidity, and the region where the front grid compression portion is provided has low rigidity. Therefore, on the front side where urine is discharged, a region having relatively low rigidity is provided while maintaining diffusibility by the front lattice compression portion, so that the absorbent body is easily deformed. This makes it easier for the absorber to come closer to the wearer's body (specifically, the urination hole), so that the absorber can easily absorb urine. On the other hand, on the rear side where the stool is discharged, the rear lattice compressing portion maintains the diffusibility, but a region with relatively high rigidity is provided, so that the absorbent body is less likely to deform. This makes it difficult for the absorbent body to enter the groove of the buttocks (gluteal cleft), and a space for containing excrement (stool) can be secured.

According to a preferred aspect, the pressing section may further include a third pressing section having a pattern different from the grid pattern in plan view of the absorbent body. A said 3rd pressing part may be provided in front rather than a said 2nd pressing part.

When the absorber on the rear side of the third pressing portion deforms, the rigidity of the third pressing portion makes it difficult for the portion on the front side of the third pressing portion to interlock with the deformation of the absorber on the rear side. Thereby, deformation|transformation of the front side part can be suppressed rather than a 3rd pressing part. Therefore, wrinkles are less likely to occur in the portion on the front side of the third pressing portion, and leakage of excrement from the ventral side can be suppressed.

According to a preferable aspect, the third pressing section may be provided on the front side of the first pressing section. In a plan view of the absorbent body, the area per unit area occupied by the third pressing section may be larger than the area per unit area occupied by the first pressing section.

As a result, since the rigidity of the region where the third pressing portion is provided is higher than the rigidity of the region where the first pressing portion is provided, deformation of the absorbent body in the front side of the third pressing portion is suppressed. can be suppressed.

According to one preferred aspect, the absorbent body may have an absorbent core comprising an absorbent material that absorbs liquid. The absorbent core may have a constricted portion in the crotch region in which both side edges in the width direction of the absorbent core are constricted inward in the width direction in a plan view of the absorbent body. A said 3rd pressing part may be provided in the front side rather than the said constriction part.

Since the length of the absorbent core in the width direction is reduced by the constricted portion, when the wearer's leg pinches the constricted portion, the portion sandwiched between the legs is likely to be deformed, and the wearer's stiffness is reduced due to the rigidity of the absorbent body. It is possible to suppress the sense of incompatibility. In addition, since the third compressed portion is provided on the front side of the constricted portion, the deformation of the part sandwiched between the legs of the wearer is not hindered, and the rigidity of the third compressed portion allows the leg to move. It is possible to suppress the deformation of the sandwiched portion from interlocking with the portion on the front side of the third pressing portion.

According to a preferred aspect, the absorbent article may have an outer covering provided at least in the front region. A said 3rd pressing part may overlap with the said exterior body in the said thickness direction.

Due to the rigidity of the third pressing portion, it is possible to suppress the deformation of the exterior body in conjunction with the deformation of the absorber. As a result, wrinkles are less likely to occur in the exterior body, and leakage of excrement from the ventral side can be suppressed.

According to a preferred aspect, the third pressing part straddles the center of the absorbent article in the width direction, and has a convex shape rearward in a plan view of the absorbent body. It may extend in the width direction.

As a result, when a part of the absorbent body provided on the rear side of the third pressing portion is deformed, the deformation of the absorbent body is released to the outside in the width direction along the convex shape of the third pressing portion. . Therefore, it is possible to suppress the deformation of the absorbent body in the portion on the front side of the third pressing portion.

According to a preferred aspect, the first pressing section may be composed of a plurality of pressing sections intermittently provided to have the lattice pattern.

Thereby, compared with the case where a 1st pressing part is comprised by the pressing part which extends continuously, it can suppress that the rigidity of an absorber becomes high by a 1st pressing part. Therefore, it becomes easy to fit the absorbent body to the wearer's body while maintaining the diffusibility.

A method for manufacturing an absorbent body for an absorbent article according to one aspect includes a pressing step of providing a pressed portion by pressing at least an absorbent core in a thickness direction. In the pressing step, as the pressing portions, a first pressing portion having a grid-like pattern in a plan view of the absorber and a second pressing portion having a pattern different from the grid-like pattern in a plan view of the absorber. and set.

Thereby, in the manufactured absorbent body, the rigidity can be changed between the region where the first pressing portion is provided and the region where the second pressing portion is provided. Therefore, by providing the second pressing part in addition to the first pressing part, the twisting of the absorbent body is suppressed and the wearer's comfort is improved by providing the second pressing part in addition to the first pressing part, while the first pressing part has the diffusibility of the excrement on the absorbent body. It is possible to manufacture an absorbent body for an absorbent article that is compatible with the fit of the absorbent body to the body.

According to a preferred aspect, the pressing step may include a step of covering the absorbent core with a core wrap sheet forming a core wrap. In the pressing step, the pressing portion may be provided by pressing the absorbent core and the core wrap sheet.

This makes it possible to manufacture an absorbent body for an absorbent article that can maintain the diffusibility of excrement in a case where the absorbent body has a core wrap covering the absorbent core.

According to a preferred aspect, in the pressing step, the first pressing is performed by pressing the absorbent core and the core wrap sheet with a first protrusion provided on the outer peripheral surface of at least one of a pair of first rolls. A step of providing a portion, and a step of providing the second pressing portion by pressing the absorbent core and the core wrap sheet with a second convex portion provided on the outer peripheral surface of at least one of a pair of second rolls; may have

In one roll, since the first convex portion and the second convex portion cannot be arranged at the same position, the positions at which the first pressing portion and the second pressing portion are provided can be restricted. Therefore, by using the first roll and the second roll, the first pressing section and the second pressing section can be provided at arbitrary positions.

According to a preferred aspect, in the pressing step, when one of the first pressing portion and the second pressing portion is provided in a pressing region in which the other pressing portion is provided, in the conveying direction, the The absorbent core and the core wrap sheet may be compressed only in a partial area of the compressed area.

As a result, it is possible to prevent the compressed regions of the core wrap sheet from being continuously compressed by compressing only a part of the compressed regions in the conveying direction. Therefore, damage to the core wrap sheet due to compression can be reduced, and breakage of the core wrap sheet can be suppressed.

According to a preferred aspect, the pressing step includes a step of providing one of the first pressing portion and the second pressing portion that is deeply pressed in the thickness direction, and and a step of providing the other pressing portion of the first pressing portion and the second pressing portion after the provision.

If the core wrap sheet is pressed deeply after the rigidity of the core wrap sheet has been increased by the compression, the core wrap sheet having high rigidity is difficult to stretch, and there is a risk that the core wrap sheet will break. Therefore, by compressing deeply in the thickness direction, a core wrap sheet provided with a deep compressed portion is shallowly compressed, so that the amount of change in the thickness direction of the core wrap sheet during compression can be reduced. Therefore, it is possible to suppress tearing of the core wrap sheet in the case of providing the shallow compressed portion and the deep compressed portion.

An apparatus for manufacturing an absorbent body for an absorbent article according to one aspect has a pressing device that provides pressing portions by pressing at least an absorbent core with a plurality of convex portions. The plurality of convex portions include a first convex portion provided with a first compressed portion having a grid pattern in plan view of the absorber, and a first convex portion having a pattern different from the grid pattern in plan view of the absorber. and a second convex portion provided with two compressed portions.

Thereby, in the manufactured absorbent body, the rigidity can be changed between the region where the first pressing portion is provided and the region where the second pressing portion is provided. Therefore, by providing the second pressing part in addition to the first pressing part, the twisting of the absorbent body is suppressed and the wearer's comfort is improved by providing the second pressing part in addition to the first pressing part, while the first pressing part has the diffusibility of the excrement on the absorbent body. It is possible to manufacture an absorbent body for an absorbent article that is compatible with the fit of the absorbent body to the body.

As described above, in the absorbent article 1 , the rigidity of the absorbent body 50 can be changed between the region where the first pressing portions 551 are provided and the region where the second pressing portions 552 are provided. Therefore, since the deformation of the absorbent body 50 can be controlled, while the excretion on the absorbent body 50 can be diffused by the first compressing part 551, the second compressing part 551 and the second compressing part By providing 552, it is possible to achieve both suppression of twisting of the absorbent body 50 and good fit of the absorbent body 50 to the wearer's body.

Moreover, in a plan view of the absorbent body 50, the area occupied by the second pressing portions 552 per unit area is larger than the area occupied by the first pressing portions 551 per unit area. As a result, the rigidity of the region where the second pressing portions 552 are provided is higher than the rigidity of the region where the first pressing portions 551 are provided, so deformation of the absorber 50 can be suppressed. In addition, in the embodiment, since the area of the region R1 in which the grid pattern is formed by the first pressing part 551 is larger than the area of the second pressing part 552, the second pressing part 552 is the same as the first pressing part It is provided in a narrow range compared to 551. Therefore, by narrowing down the region with high rigidity to a narrow range, it is possible to suppress deterioration in the wearing comfort of the absorbent article 1 due to the rigidity.
Further, in the crotch region S3, the absorber 50 is easily deformed in the width direction W by being sandwiched between the wearer's legs. By providing the second compressed portion 552 in the crotch region S3, it is possible to suppress deformation of the absorber 50 due to being sandwiched between the wearer's legs.

Moreover, since the second pressing portion 552 is provided in the rear crotch region S3R, the rigidity of the absorbent body 50 in the rear crotch region S3R can be increased. This makes it difficult for the absorbent body 50 to enter the groove of the buttocks (gluteal cleft), and a space for containing excrement (stool) can be secured.

In addition, since the pressing portion 55 has the third pressing portion 553, when the absorbent body on the rear side of the third pressing portion 553 is deformed, the rigidity of the third pressing portion 553 causes the It becomes difficult for the front side portion to interlock with the deformation of the absorbent body on the rear side. Thereby, the deformation of the portion on the front side of the third pressing portion 553 can be suppressed. Therefore, wrinkles are less likely to occur in the portion on the front side of the third pressing portion 553, and leakage of excrement from the ventral side can be suppressed.

In addition, since the length of the absorbent core 51 in the width direction is reduced by the constricted portion 512, when the wearer's leg pinches the constricted portion 512, the part sandwiched between the legs is easily deformed. Since the third compressed portion 553 is provided on the front side of the constricted portion 512 , the wearer can suppress discomfort caused by the rigidity of the absorbent body 50 .

In addition, since the third compressed portion 553 is provided on the front side of the constricted portion 512, the deformation of the portion sandwiched between the legs of the wearer is not hindered, and the rigidity of the third compressed portion 553 allows the , the deformation of the portion sandwiched between the legs can be suppressed from interlocking with the portion on the front side of the third pressing portion 553 . Since the portion on the front side of the third pressing portion 553 is less likely to be deformed, wrinkles are less likely to occur, and leakage of excrement from the ventral side can be suppressed.

In addition, since the third pressing portion 553 overlaps the front exterior body 20 in the thickness direction T, the stiffness of the third pressing portion 553 prevents the deformation of the front exterior body 20 in conjunction with the deformation of the absorber 50. can be suppressed. As a result, wrinkles are less likely to occur in the front exterior body 20, and leakage of excrement from the ventral side can be suppressed.

Further, when a part of the absorbent body 50 provided on the rear side of the third pressing portion 553 is deformed, the deformation of the absorbent body 50 extends in the width direction W along the convex shape of the third pressing portion 553. escaped to the outside. Therefore, it is possible to suppress the deformation of the absorbent body in the portion on the front side of the second front side pressing portion.

In addition, since the first pressing part 551 is composed of a plurality of pressing parts, the first pressing part 551 absorbs more energy than the case where the first pressing part 551 is composed of continuously extending pressing parts. An increase in the rigidity of the body 50 can be suppressed. Therefore, it becomes easy to fit the absorbent body to the wearer's body while maintaining the diffusibility.

FIG. 6 is a diagram for explaining the absorbent body manufacturing apparatus according to the embodiment. FIG. 6A is a diagram for explaining the rolls of the first pressing device, and is a developed view of the outer peripheral surface of the rolls of the first pressing device developed on a plane. FIG. 6B is a schematic cross-sectional view taken along line F6B-F6B in FIG. 6A. FIG. 6C is a diagram for explaining the first roll of the second pressing device, and is a developed view of the outer peripheral surface of the roll of the second pressing device developed on a plane.

A direction in which components are conveyed in the manufacturing process is indicated as a conveying direction MD, a direction intersecting with the conveying direction is indicated as a crossing direction CD, and a direction orthogonal to the conveying direction MD and the crossing direction CD is indicated as a transverse direction TD.

The absorbent body 50 can be manufactured using the manufacturing apparatus 100 according to the embodiment. The manufacturing device 100 may have a coating device 120 , a pressing device 130 and a cutting device 140 . The manufacturing apparatus 100 may have a transport device for transporting each member.

The covering device 120 is a device that folds back the core wrap sheet 52C so that the core wrap sheet 52C covers the absorbent core 51 . The main body of the covering device 120 may be a pair of bending guide members (not shown) arranged side by side in the CD direction. The coating device 120 is used in step S20, which will be described later.

The compressing device 130 is a device that provides the compressing portion 55 by compressing at least the absorbent core with a plurality of convex portions. The press 130 may comprise a first press 131 and a second press 132 .

The first pressing device 131 is a device for providing the first pressing portion 551 . The first pressing device 131 may have a pair of upper and lower first rolls 131A and 131B as an example of a pair of rotating members. The pair of first rolls 131A and 131B are supported by bearings (not shown) and are thereby rotatable around a rotation axis parallel to the CD direction. Therefore, the absorbent continuous body 50C fed into the space between the outer peripheral surfaces of the pair of first rolls 131A and 131B passes through the space G41 and is sent downstream in the MD direction.

As shown in FIGS. 6A and 6B, a first protrusion 151 may be provided on the outer peripheral surface 131S of the first roll 131A. The first convex portion 151 may have, for example, a linear convex portion 151a for forming the linear compressed portion 551a and a curved convex portion 151b for forming the curved compressed portion 551b. The outer peripheral surface of the first roll 131B may be a smooth surface without the first protrusions 151 .

The second pressing device 132 is a device for providing the second pressing portion 552 . The second pressing device 132, like the first pressing device 131, may have a pair of upper and lower second rolls 132A and 132B. A description of the configuration of the second rolls 132A and 132B that are the same as those of the first rolls 131A and 131B will be omitted.

As shown in FIGS. 6C and 6D, the outer peripheral surface 132S of the second roll 132A may be provided with a second convex portion 152 for forming the second pressing portion 552. As shown in FIG. Moreover, the 3rd convex part 153 for forming the 3rd pressing part 553 may be provided in the outer peripheral surface 132S of the 2nd roll 132A. The outer peripheral surface of the second roll 132</b>B may be a smooth surface without the second protrusions 152 and the third protrusions 153 .

The height of the second protrusion 152 is higher than the height of the first protrusion 151 in the transverse direction TD. Therefore, the second convex portion 152 can be compressed more deeply than the first convex portion 151 . Moreover, since the height of the third protrusion 153 is higher than the height of the first protrusion 151 , the third protrusion 153 can be compressed more deeply than the first protrusion 151 .

As shown in FIG. 5 , the second compressor 132 may be provided upstream of the first compressor 131 .

The cutting device 140 is a device for cutting an absorbent continuous body 50C in which the absorbent bodies 50 are continuous in the front-rear direction L. As shown in FIG. The cutting device 140 may have, for example, a pair of upper and lower third rolls 140A and 140B. The third roll 140A may be a cutter roll having cutter blades 141 on the outer peripheral surface of the third roll 140A. Third roll 140B may be an anvil roll that receives cutter blade 141 .

Note that existing methods can be used for methods that are not described in this embodiment. Moreover, the manufacturing method described below is merely an example, and other manufacturing methods can be used.

As shown in FIG. 5, the manufacturing method of the absorbent body 50 according to this embodiment includes steps S10 to S40.

Step S10 is a step of arranging the absorbent core 51 on the core wrap sheet 52C forming the core wrap 52 . In step S10, the absorbent core 51 manufactured by laminating the absorbent material may be arranged on the core wrap sheet 52C.

Note that the absorbent core 51 may have a bending guide portion 515 . The bending guide portion 515 may be formed by reducing the lamination amount of the absorbent material in the bending guide portion 515 .

Step S20 is a step of covering the absorbent core 51 with the core wrap sheet 52C. Step S20 can be performed using the coating device 120 .

In step S20, each end in the CD direction of the core wrap sheet 52C is folded to be positioned above the absorbent core 51, and folded back inward in the CD direction. On the absorbent core 51, the core wrap sheet 52C is folded up and down to cover the outer peripheral surface of the absorbent core 51 with the core wrap sheet 52C.

Step S30 is a compressing step of compressing at least the absorbent core 51 in the thickness direction T to provide the compressed portion 55 . In step S30, as the pressing portions 55, a first pressing portion 551 having a grid pattern in plan view of the absorber 50, and a second pressing portion 552 having a pattern different from the grid pattern in plan view of the absorber 50. and set. In step S<b>30 , a third pressing portion 553 may be further provided as the pressing portion 55 . In step S30, the compressed portion 55 may be provided by compressing the absorbent core 51 and the core wrap sheet 52C.

Step S30 may include step S32 and step S34. Step S<b>32 can be performed using the second pressing device 132 and step S<b>34 can be performed using the first pressing device 131 .

In step S32, a second pressing portion 552 is provided by pressing the absorbent core 51 and the core wrap sheet 52C with a second convex portion 152 provided on the outer peripheral surface 132S of at least one of the pair of second rolls 132A and 132B. . Similarly, a third pressing portion 553 is provided by pressing the absorbent core 51 and the core wrap sheet 52C with a third convex portion 153 provided on the outer peripheral surface 132S of at least one of the pair of second rolls 132A and 132B. you can

In step S34, a first pressing portion 551 is provided by pressing the absorbent core 51 and the core wrap sheet 52C with a first convex portion 151 provided on the outer peripheral surface 131S of at least one of the pair of first rolls 131A and 131B. . Specifically, the linearly compressed portion 551a is provided by compressing the absorbent core 51 and the core wrap sheet 52C with the linear convex portion 151a. A bent compressed portion 551b is provided by compressing the absorbent core 51 and the core wrap sheet 52C with the bent convex portion 151b.

In step S32, a second pressing portion 552 that is deeply pressed in the thickness direction T is provided. Further, a third pressing portion 553 that is deeply pressed in the thickness direction T may be provided. On the other hand, in step S34, the first pressing portion 551 that is shallowly pressed in the thickness direction T is provided after the second pressing portion is provided.
In step S30, the first pressing portion 551 is provided in the pressing region where the second pressing portion 552 is provided. In step S34, the absorbent core 51 and the core wrap sheet 52C are compressed only in a partial region of the compression region (that is, the region where the second compression portions 552 are provided) in the transport direction MD.
Therefore, the absorbent core 51 and the core wrap sheet 52C are not compressed in all the compression regions. Similarly, the absorbent core 51 and the core wrap sheet 52C are compressed only in a part of the region where the third compressing portion 553 is provided.

Step S40 is a step of cutting the continuous absorption body 50C. Step S40 can be performed using the cutting device 140 . The absorbent continuum 50C is cut at the same position as the front edge 51F of the absorbent core 51 or at a position on the front side of the front edge 51F of the absorbent core 51 . Thereby, the absorber 50 can be manufactured.

In the absorbent body 50 manufactured by the manufacturing method of the absorbent body 50 according to the embodiment, the rigidity is changed between the region in which the first pressing portion 551 is provided and the region in which the second pressing portion 552 is provided. be able to. Therefore, even though the first compressing portion 551 has the diffusibility of the excrement on the absorbent body 50 , by providing the second compressing portion 552 in addition to the first compressing portion 551 , the twist of the absorbent body 50 can be reduced. It is possible to manufacture the absorbent body 50 of the absorbent article 1 that is compatible with restraint and fit of the absorbent body 50 to the wearer's body. Moreover, the absorbent article 1 can be manufactured using the absorbent body 50 manufactured as described above.

In step S30, the absorbent core 51 and the core wrap sheet 52C are compressed to provide the compressed portion 55. Therefore, in the case where the absorbent body 50 has the core wrap 52 covering the absorbent core 51, the diffusibility of excrement is improved. An absorbent body 50 according to the absorbent article 1 that can be maintained can be manufactured.

Moreover, step S30 has step S32 in which the second pressing device 132 is used and step S34 in which the first pressing device 131 is used. Since the first convex portion 151 and the second convex portion 152 cannot be arranged at the same position in one roll, the positions at which the first pressing portion 551 and the second pressing portion 552 are provided can be restricted. Therefore, by using the first rolls 131A and 131B and the second rolls 132A and 132B, the first pressing section 551 and the second pressing section 552 can be provided at arbitrary positions.

Further, if the core wrap sheet 52C is deeply compressed in a state in which the rigidity of the core wrap sheet 52C is increased by compression, the core wrap sheet 52C having high rigidity is difficult to stretch, and there is a risk that the core wrap sheet 52C will break. Therefore, in step S30, by pressing deeply in the thickness direction T, the core wrap sheet 52C provided with the second pressing portion 552 and the third pressing portion 553, which are deep pressing portions, is shallowly pressed, so that the , the amount of change in the thickness direction T of the core wrap sheet 52C can be reduced. Therefore, in the case of providing the shallow compressed portion 55 and the deep compressed portion 55, it is possible to suppress tearing of the core wrap sheet 52C.
Further, in step S34, the absorbent core 51 and the core wrap sheet 52C are compressed only in a partial region of the compression region (that is, the region where the second compression portions 552 are provided) in the transport direction MD. Thereby, it is possible to prevent the compressed region of the core wrap sheet 52C from being continuously compressed. Therefore, damage to the core wrap sheet 52C due to compression can be reduced, and tearing of the core wrap sheet 52C can be suppressed.

(4) Modifications Next, each modification will be described with reference to FIG. FIG. 7 is a schematic cross-sectional view of an absorbent body according to a modification. In addition, the description similar to the above-mentioned embodiment is abbreviate|omitted.

It may have a rear grate compression portion 551R. Also, the rear grid compression part 551R may have a grid pattern different from that of the front grid compression part 551F. As shown in FIG. 7, in a plan view of the absorbent body 50, the area per unit area occupied by the rear lattice compression portion 551R may be larger than the area per unit area occupied by the front lattice compression portion 551F.

The front lattice pressing portion 551F may be arranged between the third pressing portion 553 and the second pressing portion 552 in the front-rear direction L. The rear lattice pressing part 551R may be arranged on the rear side of the second pressing part 552 in the front-rear direction L.

As shown in FIG. 7, the first pressing portion 551 and the second pressing portion 552 may not overlap. In a plan view of the absorber 50 , the second pressing portion 552 may be provided at a position separated from the first pressing portion 551 . A separation distance in the front-rear direction L between the first pressing part 551 and the second pressing part 552 may be longer than the length in the front-rear direction L of one grid formed by the first pressing parts 551 .
Specifically, the separation distance L21 in the front-rear direction L between the front lattice compression portion 551F and the second compression portion 552 may be longer than the front lattice length L11. In addition, in FIG. 7, the separation distance L21 is shorter than the length L11.

In addition, the separation distance L22 in the front-rear direction L between the rear lattice compression portion 551R and the second compression portion 552 is the rear lattice length L12, which is the length of one lattice formed by the rear lattice compression portion 551R in the front-rear direction L. longer than
Moreover, the separation distance in the front-rear direction L between the first pressing portion 551 and the third pressing portion 553 may be longer than the length in the front-rear direction L of one grid formed by the first pressing portions 551 . Specifically, the separation distance L3 in the front-rear direction L between the front lattice compression portion 551F and the third compression portion 553 is the length of one lattice in the front-rear direction L formed by the front lattice compression portion 551F. It may be longer than the length L11. In addition, in FIG. 7, the separation distance L3 is longer than the front lattice length L11.

As shown in FIG. 7 , the third pressing portion 553 may be provided on the front side of the first pressing portion 551 . In a plan view of the absorbent body 50, the area per unit area occupied by the third pressing portions 553 may be larger than the area per unit area occupied by the first pressing portions.

As described above, in the absorbent article according to the modified example, the second pressing portion 552 is provided at a position separated from the first pressing portion 551 in the plan view of the absorbent body 50 . and the second pressing portion 552 are provided continuously, the force applied to one of the first pressing portion 551 and the second pressing portion 552 is less likely to be transmitted to the other. Therefore, the first pressing part 551 and the second pressing part 552 are less likely to be affected by each other, and the functions of the first pressing part 551 and the second pressing part 552 can be exhibited.

In addition, the separation distance L21 and/or the separation distance L22 in the front-rear direction L between the first pressing portion 551 and the second pressing portion 552 is longer than the length in the front-rear direction L of one lattice formed by the first pressing portion 551. When it is long, the force applied to one of the first pressing portion 551 and the second pressing portion 552 is more difficult to be transmitted to the other. Therefore, each function of the 1st pressing part 551 and the 2nd pressing part 552 can be exhibited further. Similarly, when the separation distance L3 in the front-rear direction L between the first pressing portion 551 and the third pressing portion 553 is longer than the length in the front-rear direction L of one grid formed by the first pressing portions 551, the first The force applied to one of the pressing portion 551 and the third pressing portion 553 is more difficult to be transmitted to the other. Therefore, each function of the 1st pressing part 551 and the 3rd pressing part 553 can be exhibited further.

Further, in a plan view of the absorbent body 50, since the area occupied by the rear lattice compression part 551R per unit area is larger than the area occupied by the front lattice compression part 551F per unit area, the rear lattice compression part 551R is provided. The region where the front lattice compression part 551F is provided has high rigidity, and the region where the front lattice compression part 551F is provided has low rigidity. Therefore, on the front side where urine is discharged, the absorber 50 is easily deformed because a region with relatively low rigidity is provided while maintaining diffusivity by the front lattice compression portion 551F. This makes it easier for the absorbent body 50 to come close to the wearer's body (specifically, the urination hole), so that the absorbent body 50 can easily absorb urine. On the other hand, on the rear side where the stool is discharged, the absorbent body 50 is less likely to be deformed because a region with relatively high rigidity is provided while maintaining diffusibility by the rear lattice compressing portion 551R. This makes it difficult for the absorbent body 50 to enter the groove of the buttocks (gluteal cleft), and a space for containing excrement (stool) can be secured.

Further, in a plan view of the absorbent body 50, the area per unit area occupied by the third pressing portions 553 is larger than the area per unit area occupied by the first pressing portions. As a result, the rigidity of the region in which the third pressing portion 553 is provided becomes higher than the rigidity of the region in which the first pressing portion 551 is provided, so that the portion of the absorbent body on the front side of the third pressing portion 553 50 deformation can be suppressed.
