Description

Absorbent article, method of manufacturing absorber, and equipment for manufacturing absorber

The present invention relates to an absorbent article, a method for producing an absorber, and an apparatus for producing an absorber.

Conventionally, an absorbent article having an absorber provided with a lattice pressing portion having a grid-like pattern in a plan view of the absorber has been disclosed (see, for example, Patent Document 1). Since the excrement easily diffuses along the grid pattern, the diffusibility of the excrement in the absorber can be improved.

Japanese Unexamined Patent Publication No. 2016-93482

The rigidity of the absorber is low in the unsqueezed area where the lattice squeezed part is not provided. Therefore, in the unsqueezed area, the absorber is easily deformed, and the absorber is easily fitted to the wearer's body. However, the absorber tends to twist, and there is a risk that the absorption area cannot be secured.

In the area where the lattice pressing part is provided, the rigidity of the absorber increases, so that the absorber becomes difficult to twist. However, the provision of the lattice pressing portion makes it difficult for the absorber to fit the wearer's body. On the other hand, in order to make it easier for the absorber to fit the wearer's body, for example, when one lattice is provided with a large lattice pressing portion, the absorber is easily twisted and a sufficient absorption area is secured. It may not be possible.

Therefore, there is a demand for an absorbent article that has diffusivity of excrement on the absorber and can both suppress twisting of the absorber and fit the absorber to the wearer's body at the same time. There is.

The absorbent article according to one embodiment is in the front-rear direction, the width direction orthogonal to the front-rear direction, the thickness direction, the front side region, the rear side region, the front side region, and the rear side region in the front-rear direction. It has a sandwiched inseam area and at least an absorber arranged in the inseam area. The absorber is provided with a squeezed portion squeezed in the thickness direction. The squeezed portion has a first squeezed portion having a grid pattern in the plan view of the absorber and a second squeezed portion having a pattern different from the grid pattern in the plan view of the absorber.

The method for producing an absorber according to an absorbent article according to one aspect includes a pressing step of providing a pressing portion by pressing at least the absorbing core in the thickness direction. In the squeezing step, as the squeezing portion, a first squeezing portion having a grid pattern in the plan view of the absorber and a second squeezing section having a pattern different from the grid pattern in the plan view of the absorber. And.

The absorbent body manufacturing apparatus according to the absorbent article according to one aspect includes a squeezing apparatus that provides a squeezing portion by squeezing at least the absorbing core by a plurality of convex portions. The plurality of convex portions have a first convex portion provided with a first pressing portion having a grid-like pattern in the plan view of the absorber, and a first convex portion having a pattern different from the grid-like pattern in the plan view of the absorber. It has a second convex portion for which two pressing portions are provided.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
The absorbent article according to one aspect is in the front-rear direction, the width direction orthogonal to the front-rear direction, the thickness direction, the front side region, the rear side region, the front side region and the rear side region in the front-rear direction. It has a sandwiched inseam area and at least an absorber arranged in the inseam area. The absorber is provided with a squeezed portion squeezed in the thickness direction. The squeezed portion has a first squeezed portion having a grid pattern in the plan view of the absorber and a second squeezed portion having a pattern different from the grid pattern in the plan view of the absorber. As a result, the rigidity of the absorber can be changed between the region where the first squeezed portion is provided and the region where the second squeezed portion is provided. Therefore, since the deformation of the absorber can be controlled, the second squeezed portion is provided in addition to the first squeezed portion while having the diffusivity of excrement on the absorber by the first squeezed portion. , It is possible to suppress the twisting of the absorber and to fit the absorber to the wearer's body at the same time.

According to a preferred embodiment, in the plan view of the absorber, the area occupied by the second pressed portion per unit area may be larger than the area occupied by the first pressed portion per unit area. As a result, the rigidity of the fixed region including the second squeezed portion (the region including the region where the second squeezed portion is provided and the region around it) is increased to the fixed region including the first squeezed portion (the first squeezed portion is provided). Since it is higher than the rigidity of the area obtained by combining the area around the area and the area around the area), the deformation of the absorber can be suppressed.

According to a preferred embodiment, the second squeezing portion may be provided in the inseam region. In the inseam area, the absorber is easily deformed in the width direction by being pinched by the wearer's legs. Therefore, by providing at least the second squeezing portion in the inseam region, the rigidity of the inseam region can be increased by the second squeezing portion, and the deformation of the absorber due to being pinched by the wearer's leg can be suppressed.

According to a preferred embodiment, the inseam region may have a posterior inseam region located posterior to the anterior-posterior center of the absorbent article. The second squeezing portion may be provided in the posterior inseam region. By providing the second squeezed portion in the posterior inseam region, the rigidity of the absorber in the posterior inseam region can be increased. As a result, it becomes difficult for the absorber to enter the groove (intergluteal cleft) of the buttocks, and a storage space for excrement (feces) can be secured.

According to a preferred embodiment, the second squeezed portion may be provided at a position distant from the first squeezed portion in the plan view of the absorber. As a result, the force applied to one of the first squeezed portion and the second squeezed portion is less likely to be transmitted to the other as compared with the case where the first squeezed portion and the second squeezed portion are continuously provided. .. Therefore, the first squeezed portion and the second squeezed portion are less likely to be influenced by each other, and the functions of the first squeezed portion and the second squeezed portion can be exhibited.

According to a preferred embodiment, in a plan view of the absorber, the distance between the first squeezed portion and the second squeezed portion in the front-rear direction is determined by the front-rear distance of one lattice composed of the first squeezed portion. It may be longer than the length in the direction. As a result, the distance between the first squeezed portion and the second squeezed portion is shorter than the length of one lattice of the first squeezed material, so that the first squeezed portion and the second squeezed portion are separated from each other. It becomes more difficult for the applied force to be transmitted to the other side. Therefore, the functions of the first squeezed portion and the second squeezed portion can be further exerted.

According to a preferred embodiment, the first squeezing portion is provided on the front lattice squeezing portion provided on the front side of the center of the absorbent article in the anteroposterior direction and on the posterior side of the center in the anteroposterior direction. It may have a post-lattice squeezed portion. In the plan view of the absorber, the area occupied by the rear lattice squeezed portion per unit area may be larger than the area occupied by the front lattice squeezed portion per unit area. As a result, the region on the rear side of the center of the absorbent article in the anteroposterior direction has high rigidity, and the region on the front side of the center of the absorbent article in the anteroposterior direction has low rigidity. Therefore, urine is discharged from the region anterior to the center of the absorbent article in the anteroposterior direction, and the absorber is easily deformed because the rigidity is relatively low while maintaining diffusivity by the anterior lattice pressing portion. As a result, the absorber can easily approach the wearer's body (specifically, the urination port), so that the absorber can easily absorb urine. On the other hand, on the rear side where stool is discharged, the absorber is less likely to be deformed because a region having relatively high rigidity is provided while maintaining diffusivity by the rear lattice pressing portion. As a result, it becomes difficult for the absorber to enter the groove (intergluteal cleft) of the buttocks, and a storage space for excrement (feces) can be secured.

According to a preferred embodiment, the squeezed portion may further include a third squeezed portion having a pattern different from the grid pattern in the plan view of the absorber. The third squeezing portion may be provided on the front side of the second squeezing portion. According to this aspect, when the absorber on the rear side of the third squeezed portion is deformed, the portion on the front side of the third squeezed portion is deformed on the rear side due to the rigidity of the third squeezed portion. It becomes difficult to work together. As a result, deformation of the portion in front of the third squeezed portion can be suppressed. Therefore, wrinkles are less likely to occur in the portion in front of the third squeezed portion, and the leakage of excrement from the ventral side can be suppressed.

According to a preferred embodiment, the third squeezing portion may be provided on the front side of the first squeezing portion. In the plan view of the absorber, the area occupied by the third pressed portion per unit area may be larger than the area occupied by the first pressed portion per unit area. As a result, the rigidity of the region where the third squeezed portion is provided becomes higher than the rigidity of the region where the first squeezed portion is provided, so that the absorber in the portion in front of the third squeezed portion is deformed. It can be suppressed.

According to a preferred embodiment, the absorber may have an absorbent core containing an absorbent material that absorbs the liquid. The absorption core may have a constricted portion in the inseam region in which both side edges of the absorption core in the width direction are constricted inward in the width direction in a plan view of the absorber. The third pressing portion may be provided on the front side of the constricted portion. According to this aspect, since the length of the absorption core in the width direction is reduced by the constricted portion, when the wearer's leg sandwiches the constricted portion, the portion sandwiched between the legs is easily deformed, and the wearer can use the constricted portion. It is possible to suppress a sense of discomfort caused by the rigidity of the absorber. Further, since the third squeezed portion is provided on the front side of the constricted portion, the leg is formed by the rigidity of the third squeezed portion without hindering the deformation of the portion sandwiched between the wearer's legs. It is possible to prevent the deformation of the sandwiched portion from interlocking with the portion on the front side of the third pressed portion.

According to a preferred embodiment, the absorbent article may have at least an exterior body provided in the anterior region. The third squeezed portion may overlap the exterior body in the thickness direction. According to this aspect, the rigidity of the third squeezed portion can prevent the exterior body from being deformed in conjunction with the deformation of the absorber. As a result, wrinkles are less likely to occur on the outer body, and excrement can be prevented from leaking from the ventral side.

According to a preferred embodiment, the third squeezed portion straddles the center of the absorbent article in the width direction and has a convex shape toward the rear side in a plan view of the absorber. It may extend in the width direction. As a result, when a part of the absorber provided behind the third squeezed portion is deformed, the deformation of the absorber is released to the outside in the width direction along the convex shape of the third squeezed portion. .. Therefore, it is possible to suppress the deformation of the absorber in the portion in front of the third squeezed portion.

According to a preferred embodiment, the first squeezed portion may be composed of a plurality of squeezed portions intermittently provided so as to have the grid pattern. As a result, it is possible to prevent the rigidity of the absorber from being increased by the first squeezed portion as compared with the case where the first squeezed portion is composed of the squeezed portions extending continuously. Therefore, it becomes easier to fit the absorber to the wearer's body while maintaining diffusivity.

The method for producing an absorber according to an absorbent article according to one aspect includes a pressing step of providing a pressing portion by pressing at least the absorbing core in the thickness direction. In the squeezing step, as the squeezing portion, a first squeezing portion having a grid pattern in the plan view of the absorber and a second squeezing section having a pattern different from the grid pattern in the plan view of the absorber. And. As a result, in the manufactured absorber, the rigidity can be changed between the region where the first squeezed portion is provided and the region where the second squeezed portion is provided. Therefore, while the first squeezing portion has the diffusivity of excrement on the absorber, by providing the second squeezing portion in addition to the first squeezing portion, the twisting of the absorber can be suppressed and the wearer's It is possible to manufacture an absorber related to an absorbent article that is compatible with the fit of the absorber to the body.

According to a preferred embodiment, the squeezing step may include a step of covering the absorption core with a core wrap sheet constituting the core wrap. In the pressing step, the pressing portion may be provided by pressing the absorption core and the core wrap sheet. Thereby, in the case where the absorber has a core wrap covering the absorbent core, it is possible to produce an absorber related to an absorbent article capable of maintaining the diffusivity of excrement.

According to a preferred embodiment, in the squeezing step, the first squeezing is performed by squeezing the absorption core and the core wrap sheet by a first convex portion provided on at least one outer peripheral surface of the pair of first rolls. A step of providing the portion, and a step of providing the second squeezed portion by squeezing the absorption core and the core wrap sheet by a second convex portion provided on at least one outer peripheral surface of the pair of second rolls. May have. According to this aspect, since the first convex portion and the second convex portion cannot be arranged at the same position in one roll, the positions where the first squeezed portion and the second squeezed portion are provided can be restricted. Therefore, by using the first roll and the second roll, it is possible to provide the first squeezed portion and the second squeezed portion at arbitrary positions.

According to a preferred embodiment, in the squeezing step, when the other squeezing portion is provided in the squeezing region where one of the first squeezing portion and the second squeezing portion is provided, the squeezing portion is provided in the transport direction. The absorption core and the core wrap sheet may be squeezed only in a part of the squeezed region. As a result, it is possible to prevent the squeezed region of the core wrap sheet from being continuously squeezed by squeezing only a part of the squeezed region in the transport direction. Therefore, damage to the core wrap sheet due to squeezing can be reduced, and tearing of the core wrap sheet can be suppressed.

According to a preferred embodiment, the squeezing step includes a step of providing one of the first squeezing portion and the second squeezing portion that is deeply squeezed in the thickness direction, and the one squeezing portion. After being provided, it may have a step of providing the other pressing portion of the first pressing portion and the second pressing portion. According to this aspect, if the core wrap sheet is deeply squeezed in a state where the rigidity of the core wrap sheet is increased by squeezing, the highly rigid core wrap sheet is difficult to stretch, and therefore the core wrap sheet may be torn. Therefore, the amount of change in the thickness direction of the core wrap sheet at the time of squeezing can be reduced by squeezing the core wrap sheet provided with the deeply squeezed portion by deeply squeezing in the thickness direction. Therefore, when a shallow pressing portion and a deep pressing portion are provided, it is possible to prevent the core wrap sheet from being torn.

The absorbent body manufacturing apparatus according to the absorbent article according to one aspect includes a squeezing apparatus that provides a squeezing portion by squeezing at least the absorbing core by a plurality of convex portions. The plurality of convex portions have a first convex portion provided with a first pressing portion having a grid-like pattern in the plan view of the absorber, and a first convex portion having a pattern different from the grid-like pattern in the plan view of the absorber. It has a second convex portion for which two pressing portions are provided. As a result, in the manufactured absorber, the rigidity can be changed between the region where the first squeezed portion is provided and the region where the second squeezed portion is provided. Therefore, while the first squeezing portion has the diffusivity of excrement on the absorber, by providing the second squeezing portion in addition to the first squeezing portion, the twisting of the absorber can be suppressed and the wearer's It is possible to manufacture an absorber related to an absorbent article that is compatible with the fit of the absorber to the body.

(3) Detailed Configuration of Absorber 50 The detailed configuration of the absorber 50 will be described with reference to FIGS. 2 to 4. The absorber 50 is provided with a squeezed portion 55 squeezed in the thickness direction T. The squeezing section 55 has a first squeezing section 551 and a second squeezing section 552. The squeezing section 55 may further include a third squeezing section 553.

The first squeezed portion 551 has a grid pattern in the plan view of the absorber 50. The first squeezing portion 551 may be composed of a plurality of squeezing portions intermittently provided so as to have a grid pattern. For example, as shown in FIG. 3, the first pressing portion 551 may be composed of a linear pressing portion 551a extending linearly and a bending pressing portion 551b extending while bending. The first squeezing portion 551 may or may not extend from the front edge 50F of the absorber 50 to the trailing edge 50R (see FIG. 3). The first squeezing portion 551 may be provided at the center of the absorber 50 in the width direction W. The first squeezing portion 551 may not be provided at the side end portion of the absorber 50 in the width direction W. As shown in FIGS. 3 and 4, the first pressing portion 551 may be provided in a region where the absorption core 51 does not exist.

The second squeezed portion 552 has a pattern different from the grid pattern in the plan view of the absorber 50. The second pressing portion 552 may be provided in the inseam area S3. The second squeezed portion 552 is a portion where the absorber is pressed in a planar shape. The second squeezing portion 552 may be provided behind the central CL of the absorbent article 1 in the anteroposterior direction L. Therefore, the second squeezing portion 552 may be arranged in the posterior inseam region S3R. The front edge of the second squeezed portion 552 may be located posterior to the central CL of the absorbent article 1 in the anteroposterior direction L. The second squeezing portion 552 may straddle the center of the center CW of the absorbent article 1 in the width direction W. The second pressing portion 552 may extend in the width direction W. In the plan view of the absorber 50, the second squeezed portion 552 may have a rectangular shape. The length in the width direction of the second squeezing portion 552 may coincide with the length in the width direction of the region where the first squeezing portion 551 is provided. The second squeezing portion 552 may be separated from the outer edge of the absorption core and may be located inside the outer edge of the absorption core in the width direction. The second squeezing portion 552 may be arranged on the front side of the center of the posterior inseam region S3R in the anteroposterior direction L. As a result, the absorber 50 is less likely to shrink in the width direction W than the second squeezing portion 552, and it becomes easier to secure a storage space for stool. It is sufficient that at least a part of the second squeezed portion 552 is arranged in front of the center of the posterior inseam region S3R in the anteroposterior direction L, but the entire area of the second squeezed portion 552 is before and after the posterior inseam region S3R. It may be arranged in front of the center of the direction L. The trailing edge of the second squeezed portion 552 may be located anterior to the center of the posterior inseam region S3R in the anteroposterior direction L.

The absorbent article 1 may have a region where the first squeezed portion 551 and the second squeezed portion 552 overlap in a plan view of the absorber 50. In the plan view of the absorber 50, the area occupied by the second squeezed portion 552 per unit area is larger than the area occupied by the first squeezed portion 551 per unit area. As a result, the rigidity of the region where the second pressing portion 552 is provided becomes higher than the rigidity of the region where the first pressing portion 551 is provided, so that the deformation of the absorber 50 can be suppressed. In addition, in the embodiment, the area of the region R1 in which the grid pattern is formed by the first squeezed portion 551 may be larger than the area of the second squeezed portion 552. According to this configuration, the second squeezing section 552 is provided in a narrow range as compared with the first squeezing section 551. Therefore, by narrowing the region with high rigidity to a narrow range, it is possible to prevent the wearer from deteriorating the wearing comfort of the absorbent article 1 due to the rigidity.

As shown in FIG. 4, the thickness h1 of the absorber in the region where the first squeezed portion 551 is provided may be thicker than the thickness h2 of the absorber in the region where the second squeezed portion 552 is provided. Therefore, the depth of the recess in the first squeezed portion 551 may be shallower than the depth of the recess in the second squeezed portion 552. As a result, the rigidity of the first squeezed portion 551 can be reduced to the rigidity of the second squeezed portion 552, and the rigidity of the first squeezed portion 551 provided in a wider range than the second squeezed portion 552 makes the absorbent article. It is possible to suppress the deterioration of the wearing comfort of 1.

The third squeezed portion 553 has a pattern different from the grid pattern in the plan view of the absorber 50. The third squeezing section 553 is provided on the front side of the second squeezing section 552. The third squeezing portion 553 may be provided on the front side of the central CL of the absorbent article 1 in the front-rear direction L. The third pressing portion 553 may be arranged in the anterior inseam region S3F. The trailing edge of the third squeezed portion 553 may be located anterior to the center CL of the absorbent article 1 in the anteroposterior direction L, and may be located anterior to the center of the anterior inseam region S3F in the anteroposterior direction L. The third squeezing portion 553 may straddle the center of the center CW of the absorbent article 1 in the width direction W. As shown in FIG. 3, the third squeezing portion 553 may extend in the width direction W. The third squeezed portion 553 may extend in the width direction W so as to have a convex shape toward the rear side in the plan view of the absorber 50. For example, the trailing edge of the third squeezed portion 553 may be curved outward in the front-rear direction L from the inside to the outside in the width direction W. The third pressing portion 553 may have a crescent shape. The third squeezing portion 553 may be provided on the front side of the constricting portion 512. Therefore, the third pressing portion 553 may be provided on the front side of the front end edge 512F of the constricted portion 512. In the embodiment, the third pressing portion 553 is arranged so as to straddle the boundary between the front side region S1 and the inseam region S3. Therefore, the third pressing portion 553 overlaps the front exterior body 20 in the thickness direction T. The third pressing portion 553 may be arranged only in the anterior side region S1 or may be arranged only in the inseam region S3.

That is, the absorber 50 includes a region provided with only the first squeezed portion 551, a region provided with only the second squeezed portion 552, a region provided with only the third squeezed portion 553, and a first squeezed portion. A region provided with the first squeezed portion 551 and the second squeezed portion 552 and a region provided with the first squeezed portion 551 and the third squeezed portion 553 are provided. As described above, in the absorbent article 1, the rigidity of the absorber 50 can be changed between the region where the first pressing portion 551 is provided and the region where the second pressing portion 552 is provided. Therefore, since the deformation of the absorber 50 can be controlled, the first squeezed portion 551 has diffusivity of excrement on the absorber 50, and the second squeezed portion is added to the first squeezed portion 551. By providing 552, it is possible to suppress twisting of the absorber 50 and to fit the absorber 50 to the wearer's body at the same time. Further, in the inseam area S3, the absorber 50 is easily deformed in the width direction W by being sandwiched between the wearer's legs. By providing the second squeezing portion 552 in the inseam area S3, deformation of the absorber 50 due to being pinched by the wearer's legs can be suppressed.

Further, since the second pressing portion 552 is provided in the rear inseam area S3R, the rigidity of the absorber 50 in the rear inseam area S3R can be increased. As a result, the absorber 50 is less likely to enter the groove (intergluteal cleft) of the buttocks, and a storage space for excrement (feces) can be secured. Further, since the squeezing portion 55 has the third squeezing portion 553, when the absorber behind the third squeezing portion 553 is deformed, the rigidity of the third squeezing portion 553 causes it to be higher than that of the third squeezing portion 553. The front part is less likely to be linked to the deformation of the absorber on the rear side. As a result, deformation of the portion in front of the third squeezed portion 553 can be suppressed. Therefore, wrinkles are less likely to occur in the portion in front of the third squeezed portion 553, and the leakage of excrement from the ventral side can be suppressed.

Further, since the length of the absorption core 51 in the width direction is reduced by the constricted portion 512, when the wearer's leg sandwiches the constricted portion 512, the portion sandwiched between the legs is easily deformed. Since the third pressing portion 553 is provided on the front side of the constricted portion 512, the wearer can suppress a sense of discomfort due to the rigidity of the absorber 50. In addition, since the third squeezed portion 553 is provided on the front side of the constricted portion 512, the deformation of the portion sandwiched between the wearer's legs is not hindered, and the rigidity of the third squeezed portion 553 increases. It is possible to prevent the deformation of the portion sandwiched between the legs 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 excrement can be suppressed from leaking from the ventral side.

Further, since the third squeezed portion 553 overlaps with the front exterior body 20 in the thickness direction T, the front exterior body 20 is deformed in conjunction with the deformation of the absorber 50 due to the rigidity of the third squeezed portion 553. Can be suppressed. As a result, wrinkles are less likely to occur on the front exterior body 20, and excrement can be prevented from leaking from the ventral side. Further, when a part of the absorber 50 provided behind the third squeezed portion 553 is deformed, the deformation of the absorber 50 is in the width direction W along the convex shape of the third squeezed portion 553. It is escaped to the outside. Therefore, it is possible to suppress the deformation of the absorber in the portion in front of the second front pressing portion. Further, since the first squeezing portion 551 is composed of a plurality of squeezing portions, the first squeezing portion 551 absorbs the first squeezing portion 551 as compared with the case where the first squeezing portion 551 is composed of continuously extending squeezing portions. It is possible to suppress an increase in the rigidity of the body 50. Therefore, it becomes easier to fit the absorber to the wearer's body while maintaining diffusivity.

FIG. 5 is a diagram for explaining a method of manufacturing the absorber 50. FIG. 5A shows the members viewed from the transverse direction TD (upper side), and FIG. 5B shows the members viewed from the crossing direction CD. FIG. 6 is a diagram for explaining an absorber manufacturing apparatus according to an embodiment. FIG. 6A is a diagram for explaining the roll of the first squeezing device, and is a developed view of the outer peripheral surface of the roll of the first squeezing device developed on a plane. FIG. 6B is a schematic cross-sectional view taken along the F6B-F6B cross section in FIG. 6A. FIG. 6C is a diagram for explaining the first roll of the second squeezing device, and is a developed view of the outer peripheral surface of the roll of the second squeezing device developed on a plane. FIG. 6D is a schematic cross-sectional view taken along the F6D-F6D cross section in FIG. 6C. The direction in which the component parts in the manufacturing process are conveyed is shown as the transport direction MD, the direction intersecting the transport direction is shown as the cross direction CD, and the direction orthogonal to the transport direction MD and the cross direction CD is shown as the transverse direction TD.

The absorber 50 can be manufactured by using the manufacturing apparatus 100 according to the embodiment. The manufacturing apparatus 100 may include a coating apparatus 120, a squeezing apparatus 130, and a cutting apparatus 140. The manufacturing apparatus 100 may have a conveying device for conveying each member. The covering device 120 is a device for folding back the core wrap sheet 52C so that the core wrap sheet 52C covers the absorption core 51. The covering device 120 may have a pair of bending guide members (not shown) arranged side by side in the CD direction as a main body. The covering device 120 is used in the step S20 described later.

The squeezing device 130 is a device that provides the squeezing portion 55 by squeezing at least the absorption core by a plurality of convex portions. The squeezing device 130 may have a first squeezing device 131 and a second squeezing device 132. The first squeezing device 131 is a device for providing the first squeezing portion 551. The first squeezing device 131 may have a pair of upper and lower first rolls 131A and 131B as an example of the pair of rotating members. The pair of first rolls 131A and 131B are supported by bearings (not shown) so that they can rotate around a rotation axis parallel to the CD direction. Therefore, the absorption continuum 50C sent to the interval between the outer peripheral surfaces of the pair of first rolls 131A and 131B passes through the interval G41 and is sent downstream in the MD direction.

As shown in FIGS. 6A and 6B, the outer peripheral surface 131S of the first roll 131A may be provided with the first convex portion 151. The first convex portion 151 may have, for example, a linear convex portion 151a for forming the linear pressing portion 551a and a bending convex portion 151b for forming the bending pressing portion 551b. The outer peripheral surface of the first roll 131B may be a smooth surface without the first convex portion 151. The second squeezing device 132 is a device for providing the second squeezing portion 552. The second squeezing device 132 may have a pair of upper and lower second rolls 132A and 132B, similarly to the first squeezing device 131. Of the second rolls 132A and 132B, the description of the same configuration as that of the first rolls 131A and 131B will be omitted. As shown in FIG. 5, the second squeezing device 132 may be provided on the upstream side of the first squeezing device 131.

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. Further, the outer peripheral surface 132S of the second roll 132A may be provided with a third convex portion 153 for forming the third pressing portion 553. The outer peripheral surface of the second roll 132B may be a smooth surface without the second convex portion 152 and the third convex portion 153. In the transverse direction TD, the height of the second convex portion 152 is higher than the height of the first convex portion 151. Therefore, the second convex portion 152 can be squeezed deeper than the first convex portion 151. Further, since the height of the third convex portion 153 is higher than the height of the first convex portion 151, the third convex portion 153 can be pressed deeper than the first convex portion 151.

The cutting device 140 is a device in which the absorber 50 cuts the absorption continuum 50C which is continuous in the front-rear direction L. 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 a cutter blade 141 on the outer peripheral surface of the third roll 140A. The third roll 140B may be an anvil roll that receives the cutter blade 141.

For the methods not described in the present embodiment, existing methods can be used. Further, the manufacturing method described below is an example, and can be manufactured by another manufacturing method.

As shown in FIG. 5, the method for producing the absorber 50 according to the present embodiment includes steps S10 to S40. Step S10 is a step of arranging the absorption core 51 on the core wrap sheet 52C constituting the core wrap 52. In step S10, the absorption core 51 manufactured by laminating the absorption materials may be arranged on the core wrap sheet 52C. The absorption core 51 may have a bending guide portion 515. The bending guide portion 515 may be formed by reducing the amount of the absorbent material laminated in the bending guide portion 515.

Step S20 is a step of covering the absorption core 51 with the core wrap sheet 52C. Step S20 can be performed using the covering device 120. In step S20, the core wrap sheet 52C is bent so that each end in the CD direction is located above the absorption core 51, and is folded inward in the CD direction. The folded portion of the core wrap sheet 52C is folded up and down on the absorption core 51, so that the outer peripheral surface of the absorption core 51 is covered with the core wrap sheet 52C.

Step S30 is a pressing step of providing the pressing portion 55 by pressing at least the absorption core 51 in the thickness direction T. In step S30, as the pressing portion 55, the first pressing portion 551 having a grid pattern in the plan view of the absorber 50 and the second pressing section 552 having a pattern different from the grid pattern in the plan view of the absorber 50. And. In step S30, a third pressing portion 553 may be further provided as the pressing portion 55. In step S30, the pressing portion 55 may be provided by pressing the absorption core 51 and the core wrap sheet 52C. The step S30 may include a step S32 and a step S34. Step S32 can be performed using the second squeezing device 132, and step S34 can be performed using the first squeezing device 131.

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

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

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

Step S40 is a step of cutting the absorption continuum 50C. Step S40 can be performed using the cutting device 140. The absorption continuum 50C is cut at the same position as the front end edge 51F of the absorption core 51 or at a position in front of the front end edge 51F of the absorption core 51. As a result, the absorber 50 can be manufactured.

In the manufactured absorber 50 according to the method for manufacturing the absorber 50 according to the embodiment, the rigidity is changed between the region where the first squeezed portion 551 is provided and the region where the second squeezed portion 552 is provided. be able to. Therefore, while the first squeezing portion 551 has diffusivity of excrement on the absorber 50, by providing the second squeezing portion 552 in addition to the first squeezing portion 551, the absorber 50 is twisted. It is possible to manufacture the absorbent body 50 according to the absorbent article 1 which can achieve both restraint and fit of the absorbent body 50 to the wearer's body. Further, the absorbent article 1 can be manufactured by using the absorber 50 manufactured as described above.

Further, in step S30, since the squeezing portion 55 is provided by squeezing the absorption core 51 and the core wrap sheet 52C, the diffusibility of excrement is increased in the case where the absorber 50 has the core wrap 52 covering the absorption core 51. The absorber 50 according to the absorbent article 1 that can be maintained can be manufactured. Further, the step S30 includes a step S32 in which the second squeezing device 132 is used and a step S34 in which the first squeezing 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 where 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 squeezing portion 551 and the second squeezing portion 552 can be provided at arbitrary positions.

Further, if the core wrap sheet 52C is deeply squeezed while the rigidity of the core wrap sheet 52C is increased by squeezing, the highly rigid core wrap sheet 52C is difficult to stretch, so that the core wrap sheet 52C may be torn. Therefore, in step S30, the core wrap sheet 52C provided with the second pressing portion 552 and the third pressing portion 553, which are deep pressing portions by deeply pressing in the thickness direction T, is shallowly pressed to perform pressing. The amount of change in the thickness direction T of the core wrap sheet 52C can be reduced. Therefore, when the shallow pressing portion 55 and the deep pressing portion 55 are provided, it is possible to prevent the core wrap sheet 52C from being torn. Further, in step S34, the absorption core 51 and the core wrap sheet 52C are squeezed only in a part of the squeezing region (that is, the region where the second squeezing portion 552 is provided) in the transport direction MD. As a result, it is possible to prevent the pressed region of the core wrap sheet 52C from being continuously pressed. Therefore, the damage to the core wrap sheet 52C due to squeezing can be reduced, and the core wrap sheet 52C can be prevented from being torn.

(5) Modification Example Next, each modification example will be described with reference to FIG. 7. FIG. 7 is a schematic cross-sectional view of the absorber according to the modified example. The same description as in the above-described embodiment will be omitted. As shown in FIG. 7, the first squeezing portion 551 is provided on the front lattice squeezing portion 551F provided on the front side of the center CL in the anteroposterior direction L of the absorbent article 1 and on the rear side of the center CL. It may have a rear grid squeezing portion 551R. Further, the rear lattice pressing portion 551R may have a lattice pattern different from that of the front lattice pressing portion 551F. As shown in FIG. 7, in the plan view of the absorber 50, the area occupied by the rear lattice pressing portion 551R per unit area may be larger than the area occupied by the front lattice pressing portion 551F per unit area.

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 portion 551R may be arranged behind the second pressing portion 552 in the front-rear direction L. As shown in FIG. 7, the first squeezed portion 551 and the second squeezed portion 552 do not have to overlap. In the plan view of the absorber 50, the second squeezing portion 552 may be provided at a position distant from the first squeezing portion 551. The distance between the first squeezed portion 551 and the second squeezed portion 552 in the front-rear direction L may be longer than the length in the front-rear direction L of one grid composed of the first squeezed portion 551. Specifically, the separation distance L21 between the front lattice pressing portion 551F and the second pressing portion 552 in the front-rear direction L may be longer than the front lattice length L11. In FIG. 7, the separation distance L21 is shorter than the length L11.

Further, the separation distance L22 between the rear grid pressing portion 551R and the second pressing portion 552 in the front-rear direction L is the rear grid length L12 which is the length of one lattice composed of the rear grid pressing portion 551R in the front-rear direction L. May be longer than. Further, the separation distance between the first pressing portion 551 and the third pressing portion 553 in the front-rear direction L may be longer than the length in the front-rear direction L of one lattice composed of the first pressing portion 551. Specifically, the separation distance L3 between the front lattice pressing portion 551F and the third pressing portion 553 in the front-rear direction L is the length of the front-lattice L in the front-rear direction L of one lattice composed of the front lattice pressing portion 551F. It may be longer than the length L11. In FIG. 7, the separation distance L3 is longer than the front grid 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 the plan view of the absorber 50, the area occupied by the third squeezed portion 553 per unit area may be larger than the area occupied by the first squeezed portion per unit area.

As described above, in the absorbent article according to the modified example, since the second squeezing portion 552 is provided at a position away from the first squeezing portion 551 in the plan view of the absorber 50, the first squeezing portion 551 As compared with the case where the first pressing portion 551 and the second pressing portion 552 are continuously provided, 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 squeezing section 551 and the second squeezing section 552 are less likely to be influenced by each other, and the functions of the first squeezing section 551 and the second squeezing section 552 can be exhibited.

Further, the separation distance L21 and / or the separation distance L22 between the first pressing portion 551 and the second pressing portion 552 in the front-rear direction L is larger than the length in the front-rear direction L of one lattice composed of the first pressing portion 551. If it is long, the force applied to one of the first pressing portion 551 and the second pressing portion 552 becomes more difficult to be transmitted to the other. Therefore, the functions of the first squeezing section 551 and the second squeezing section 552 can be further exerted. Similarly, when the separation distance L3 between the first pressing portion 551 and the third pressing portion 553 in the front-rear direction L is longer than the length in the front-rear direction L of one lattice composed of the first pressing portion 551, the first The force applied to one of the pressing portion 551 and the third pressing portion 553 becomes more difficult to be transmitted to the other. Therefore, the functions of the first squeezing section 551 and the third squeezing section 553 can be further exerted.

Further, in the plan view of the absorber 50, the area occupied by the rear lattice pressing portion 551R per unit area is larger than the area occupied by the front lattice pressing portion 551F per unit area, so that the rear lattice pressing portion 551R is provided. The area where the front grid is squeezed has high rigidity, and the area where the front lattice pressing portion 551F is provided has low rigidity. Therefore, on the front side where urine is discharged, the absorber 50 is easily deformed because a region having a relatively low rigidity is provided while maintaining diffusivity by the front lattice pressing portion 551F. As a result, the absorber 50 can easily approach the wearer's body (specifically, the urination port), so that the absorber 50 can easily absorb urine. On the other hand, on the rear side where the stool is discharged, the absorber 50 is less likely to be deformed because a region having a relatively high rigidity is provided while maintaining diffusivity by the rear lattice pressing portion 551R. As a result, the absorber 50 is less likely to enter the groove (intergluteal cleft) of the buttocks, and a storage space for excrement (feces) can be secured.

Further, in the plan view of the absorber 50, the area occupied by the third pressed portion 553 per unit area is larger than the area occupied by the first pressed portion per unit area. As a result, the rigidity of the region where the third squeezing portion 553 is provided becomes higher than the rigidity of the region where the first squeezing portion 551 is provided, so that the absorber in the portion in front of the third squeezing portion 553 Deformation of 50 can be suppressed.
