The structure which has may be sufficient.

  The non-skin surface sheet 20 is a liquid-impermeable sheet that does not transmit liquid such as body fluid. The non-skin surface sheet 20 has a size that overlaps the skin surface sheet 10 in a plan view of the absorbent article 1. The non-skin sheet 20 may be a polyethylene sheet, a laminated nonwoven fabric mainly composed of polypropylene, a breathable resin film, a spunbond, or a sheet in which a breathable resin film is bonded to a nonwoven fabric such as spunlace. it can. Here, the plan view of the absorbent article 1 is a view of the absorbent article 1 in a developed state from a position away from the thickness direction T. The developed state of the absorbent article 1 is the state shown in FIG. 1, in which the absorbent article is not folded and the wing part 40 and the hip flap part 50 do not overlap the main body part 2 in the thickness direction T. It is.

  The absorber 30 is formed of an absorbent material that can absorb body fluid. The absorbent material includes, for example, a fiber assembly made of hydrophilic fibers, pulp, SAP, tow, and the like. The absorbent body 30 in the present embodiment includes a fiber assembly composed of a plurality of layers of tows and SAP.

The absorbent body 30 in the present embodiment is, for example, a fiber assembly made of tow is placed on a tissue, and SAP is spread on the tissue, for example, at about 80 g / m ² , and then the fiber made of tow is placed thereon. The assembly and the superabsorbent polymer (about 80 g / m ² ) are laminated, and then the fiber assembly composed of tow and the superabsorbent polymer (about 80 g / m ² ) are laminated thereon, and then, It is formed by laminating tissue and then compressing with a press, for example, compressing for 5 seconds at a pressure of 35 kg / cm ² . Although the basic weight of the absorber 30 in this embodiment changes with the number of lamination | stacking, a specific use, etc., about 10 to about 1000 g / m < ² > can be applied, for example.

  The absorber 30 has a middle-high portion 31 that is thicker than the surroundings. The middle-high portion 31 is disposed in a region including the center WC in the width direction W of the absorbent article 1. The middle-high part 31 is a part surrounded by the pressing part 32 in which the absorber 30 is compressed in the thickness direction T in the present embodiment. That is, the outer edge of the middle-high part 31 is the pressing part 32.

The granular layer 60 includes a large number of granular bodies 63 and a packaging body 64 that wraps the granular bodies 63. For example, hydrophobic resin foam beads such as polystyrene foam beads and polyolefin foam beads can be used as the granular material 63. The large number of granular materials 63 are configured to be movable within the package. The particle diameter of the resin foam beads is about 1 to 5 mm, and the bulk density is 0.01 to 0.1 g / cm ³ . The resin foam beads may be beads generally used for bedding such as cushions or pillows or futons.

  The packaging body 64 is only required to wrap the granular body 63, and a nonwoven fabric or a woven fabric can be used. The packaging body 64 only needs to have flexibility that can be deformed when pressure such as body pressure is applied. An opening may be formed in the packaging body 64. The opening of the packaging body 64 is configured not to allow the granular material 63 accommodated therein to pass therethrough.

  In addition, the granular layer 60 includes, for example, hydrophilic fibers, pulp, or fibers having water absorption properties such as SAP, and is configured so that the absorbent fibers and the granular material (resin foam beads) are not joined to each other. Also good.

  The granular layer 60 should just be arrange | positioned at the wing part 40 at least. The granular layer 60 may be arranged not only in the wing part 40 but also in the main body part 2 and the hip flap part 50. The granular layer 60 is disposed on the outer side in the width direction with respect to the fold line FL1 of the wing portion 40 in the developed state of the absorbent article 1. The fold FL1 of the wing portion 40 extends in the front-rear direction L of the absorbent article 1.

  In addition, the expansion | deployment state of the absorbent article 1 is a state shown in FIG. 1, and in the absorbent article 1 by which the plurality of folding is carried out and individually wrapped, it is the state expanded from the folded state, and a wing part 40 and the hip flap part do not overlap the main body part 2. Further, the granular layer 60 does not overlap with the crease FL1 of the wing portion 40 in the thickness direction of the absorbent article 1. In other words, the crease FL1 is not formed in the region where the granular layer 60 is arranged in a plan view of the absorbent article 1.

  A non-skin contact surface of the non-skin surface sheet 20 is provided with an adhesive region 70 to which an adhesive for fastening the absorbent article 1 to the underwear is applied. The adhesive region 70 includes a main body adhesive region 71 disposed in the main body 2, a wing adhesive region 72 disposed in the wing portion 40, and a hip flap adhesive region 73 disposed in the hip flap portion 50.

  The granular layer 60 overlaps the wing adhesive region 72 in the developed state of the absorbent article 1 (the state shown in FIG. 1). In other words, the granular layer 60 overlaps the wing adhesive region 72 in the thickness direction T. In addition, the configuration in which two members overlap in the present embodiment is a concept that includes not only a configuration in which the two members abut and directly overlap, but also a configuration in which the two members overlap indirectly through another member.

  The adhesive region 70 is covered with a release sheet in a state before use. The release sheet prevents the adhesive from deteriorating before use. The release sheet is peeled off by the wearer when worn. In addition, in the absorbent article 1 which does not have a peeling sheet, you may be comprised so that it may prevent that an adhesion area | region deteriorates before use with the packaging sheet which wraps the absorbent article 1 separately.

(2) Deformation mode at the time of wear of an absorbent article Next, the deformation mode at the time of wear of the absorbent article 1 comprised in this way is demonstrated. FIG. 4 shows a state where the absorbent article 1 is worn by the wearer (hereinafter referred to as a worn state). 4 is a cross-sectional view based on the AA cross section of FIG. FIG. 4A shows a state where the absorbent article 1 is attached to the underwear and the wearer's body pressure is not applied. FIG. 4B shows a state where the absorbent article 1 is attached to the underwear S and the body pressure of the wearer is applied.

  In the wearing state shown in FIG. 4 (b), the absorbent article 1 is sandwiched between both legs of the wearer, and a force is applied from the outside in the width direction to the inside in the width direction. When the center in the width direction of the absorbent article 1 receives a force from the outer side in the width direction toward the inner side in the width direction, the absorbent article 1 rises toward the wearer. The region that protrudes toward the wearer is a region on the inner side in the width direction from the pressing portion 32, and protrudes from the pressing portion 32 as a base point. A region outside the pressing portion 32 in the width direction is pressed inward in the width direction, and rises to the wearer side with the pressing portion 32 as a base point. Therefore, the center in the width direction of the main body portion 2 fits into the wearer's excretion opening contact area.

  In the wearing state shown in FIG. 4 (b), the wing portion 40 is subjected to a force due to the deformation of the main body portion 2 via the underwear. Specifically, the wing portion 40 is applied with a force from the skin facing surface side T1 toward the non-skin facing surface side T2, and in particular, in the region overlapping the pressing portion 32 of the wing portion 40, the skin facing surface side T1 is not. A force toward the skin facing surface side T2 is applied. The area overlapping the pressing part 32 of the wing part 40 is increased in pressure by the force from the main body part 2, and the granular material 63 in the area overlapping the pressing part 32 of the wing part 40 is located outside in the width direction and inside in the width direction. Moving. The moving direction of the granular material 63 is indicated by an arrow P in FIG. The movement destination area of the granular material in the area overlapping with the pressing part 32 of the wing part 40 is an area where the pressure is lower than the area overlapping with the pressing part 32 of the wing part 40. The granular material 63 moves from a region receiving a relatively high pressure to a region receiving a relatively low pressure. Therefore, as shown in FIG. 4B, the granular material 63 is arranged in a biased manner on both side edges in the width direction of the wing portion 40.

  In addition, the pressure with respect to the absorbent article 1 in a wearing state is applied not only in the thickness direction T but also in the width direction W and the front-rear direction L. When the pressure in the thickness direction T is applied, the granular material 63 in the granular layer 60 moves from the high pressure portion to the low pressure portion as in the case where the pressure in the width direction W and the front-back direction L is applied.

(3) Action / Effect The absorbent article 1 is used in a state of being worn on underwear or the like, and is pressed against the wearer by the underwear when worn. At this time, the wing part 40 of the absorbent article 1 is arrange | positioned at the non-skin opposing surface side of the crotch area of underwear. The crotch region of the underwear is a region that is arranged to face the wearer's excretion opening, and is a portion that is easily in contact with the wearer's body in a worn state and is subject to pressure from the wearer's body.

  Further, the pressure applied to the absorbent article 1 from the wearer varies depending on the region of the absorbent article 1. For example, the wearer and the absorbent article 1 are likely to be in close contact with each other in a region that has received a relatively high pressure, but the wearer and the absorbent article 1 are in close contact with each other in a region that has received a relatively low pressure. It is difficult to obtain sufficient fit.

  In the absorbent article 1 according to the present disclosure, the granular layer 60 changes according to the pressure received from the wearer, and the absorbent article fits the wearer's body appropriately. Specifically, the granular layer 60 provided in the wing part 40 includes a large number of granular materials, and the large number of granular materials move in the granular layer 60 according to a change in pressure. For example, the granular material 63 in the region receiving a relatively high pressure moves to the region receiving a relatively low pressure. By moving the granular material in the granular layer 60 in this way, the granular material moves to a region that has received a relatively low pressure, and the absorbent article 1 can be pressed against the wearer by the moved granular material. it can. The region subjected to the relatively low pressure is pressed against the wearer's body, the shape of the absorbent article 1 changes to conform to the shape of the wearer's body, and the wearer and the absorbent article 1 are in close contact with each other. It becomes easy. Therefore, the absorbent article 1 can be fitted to the wearer's body, particularly the excretion opening, in both the region that has received a relatively high pressure during wearing and the region that has received a relatively low pressure. Since the absorbent article 1 fits to the wearer's excretion opening, leakage of body fluid can be suppressed. Moreover, since the absorbent article 1 is pressed against the wearer's body by the granular layer 60, the absorbent article 1 is absorbed without being too close to the wearer's body as compared with a configuration in which the absorbent article 1 is pressed against the body with an elastic member or the like. The property article 1 can be put along, steaming and rubbing can be suppressed, and a feeling of wearing can be improved.

  Moreover, the granular layer 60 may be arrange | positioned on the outer side of the width direction W rather than the crease | fold FL1 in the expansion | deployment state of the absorbent article 1. FIG. The outer side in the width direction W of the wing portion 40 in the unfolded state is arranged on the non-skin facing surface side T2 of the underwear when worn. For example, when the granular layer 60 is disposed on the skin-facing surface side T1 of the underwear, the granular body 63 moves due to the pressing force of the underwear itself on the wearer side, and the pressure changes according to the body movement and the like. The granular material 63 may be difficult to move. However, by disposing the granular layer 60 on the non-skin facing surface side of the underwear, the granular body 63 can easily move due to a change in pressure according to the movement of the body. Therefore, the absorbent article 1 can be made to follow the body by a change in pressure according to the movement of the body, and the absorbent article 1 can be fitted to the wearer's body, particularly the excretion opening.

  The granular layer 60 may not overlap the crease in the thickness direction of the absorbent article 1. The fold FL1 of the wing portion 40 is a portion that is sandwiched between the wearer's legs when worn. When the granular layer 60 is disposed at the fold FL1 of the wing portion 40, the granular layer 60 may hit the wearer's leg, and the wearer may feel uncomfortable. However, since the granular layer 60 does not overlap with the crease FL1, it is possible to suppress the granular layer 60 from hitting the wearer's leg, and to prevent a sense of discomfort.

  The granular layer 60 may overlap the adhesive region 70 in the developed state of the absorbent article 1. When the adhesive region 70 and the granular layer 60 are overlapped, the underwear and the granular layer 60 can be brought into close contact with each other via the adhesive region 70, and a change in pressure from the underwear is easily transmitted to the granular layer 60.

(4) Absorbent Article in Modification Example Next, an absorbent article 1A according to Modification Example 1 and an absorbent article 1B according to Modification Example 2 will be described. In the description of the modification, the same reference numerals are used for the same configurations as those in the above-described embodiment, and the description thereof is omitted.

  FIG. 5 is a plan view of an absorbent article 1A according to the first modification. The granular layer 60 </ b> A of the absorbent article 1 </ b> A according to the modified example 1 includes a plurality of granular sections 61 divided by the separation wall 62. The separation wall 62 divides the granular layer 60A into a plurality of granular sections in the plan view of the absorbent article 1A.

  The separation wall 62 is a partition that divides the granular layer 60 into a plurality of granular sections 61. Separation wall 62 may be formed by joining package bodies that contain resin foam beads. Moreover, in the form in which the granular layer 60 has a plurality of packaging bodies and the granular bodies 63 are accommodated in each packaging body, each packaging body itself constitutes a separation wall 62 that partitions the adjacent packaging body. Further, the separation wall 62 may be formed continuously so that the granular material cannot move between the adjacent granular sections 61, or the granular body 63 can be moved between the adjacent granular sections 61. It may be formed discontinuously (intermittently).

  The separation wall 62 of the first modification is disposed along the front-rear direction L. The separation wall 62 divides the granular layer 60 into a granular section 61A located on the outer side in the width direction and a granular section 61B located on the inner side in the width direction.

  For example, when the granular layer 60 is not divided by the separation wall (when the granular body is wrapped in one package), the granular body 63 is biased in a certain direction. In this case, depending on the part of the absorbent article 1A, a state in which there are few granular materials that move according to a change in pressure at the time of wearing may occur. On the other hand, dividing the granular layer 60 by the separation wall 62 reduces the bias of the granular material included in the granular layer 60 in a certain direction, and an appropriate amount according to the portion where the magnitude of the change in pressure in the wearing state is different. Granules can be placed. In the whole granular layer 60, the shape of the absorbent article 1A can be made to easily follow the shape of the wearer's body in accordance with a change in pressure.

  Moreover, the wing adhesion area | region 72 may be arrange | positioned so that the separation wall 62 may be straddled in planar view. The wing adhesive region 72 is fastened to the underwear, and pressure from the underwear is easily applied. By disposing the wing adhesive region 72 so as to straddle the separation wall 62, a change in pressure from the underwear to the absorbent article 1A can be propagated to each of the granular sections 61 divided by the separation wall 62. Thereby, according to the change of the pressure from a body, the granular material of a some granular division moves, and the shape of a some granular division changes so that a body may be fitted.

  Also with the absorbent article 1A according to the modified example 1, the absorbent article 1A can be fitted to the wearer's body, particularly the excretion opening. Since 1 A of absorbent articles fits with a wearer's excretion opening | mouth, the leakage of a bodily fluid can be suppressed. Further, since the absorbent article 1A is pressed against the wearer's body by the granular layer 60, the absorbent article 1A is absorbed without being too close to the wearer's body as compared with a configuration in which the absorbent article 1A is pressed against the body with an elastic member or the like. It is possible to keep the adhesive article 1A along, so that the steaming and rubbing can be suppressed, and the wearing feeling can be improved.

  FIG. 6 is a plan view of an absorbent article 1B according to Modification 2. The granular layer 60 </ b> B of the absorbent article 1 </ b> B according to the modified example 2 is disposed in the wing part 40 and the main body part 2. More specifically, the granular layer 60 </ b> B is disposed across the wing part 40 and the main body part 2. In FIG. 6, the region where the granular layer 60B is arranged is shown by hatching. The granular layer 60 </ b> B has a plurality of granular sections separated by the separation wall 62. The plurality of granular sections are a granular section 61A disposed on the wing portion 40 side and a granular section 61B disposed on the main body section 2 side.

  Although the separation wall 62 of the modification 2 is arrange | positioned in the width direction outer side rather than the crease | fold FL1 of the wing part 40, it is not limited to this structure. The separation wall 62 may be disposed on the inner side in the width direction W than the fold line FL1 of the wing part 40, or the separation wall 62 may coincide with the fold line FL1 of the wing part 40. There may be provided a plurality of separation walls 62 as well as one.

  Moreover, although the granular layer 60B which concerns on the modification 2 is arrange | positioned ranging over the wing part 40 and the main-body part 2, it is not limited to this structure. The granular layer 60 </ b> B may be divided in the width direction and disposed in each of the wing part 40 and the main body part 2. The granular layer 60 arranged in the main body 2 may overlap the absorber 30.

  Since the granular layer 60B is disposed on the wing 40 and the main body 2, not only the wing 40 but also the main body 2 having the absorber 30 is absorbed by a change in pressure according to the movement of the body. The absorbent article 1B can be caused to follow the body and the absorbent article 1B can be fitted to the wearer's body.

  Further, the basis weight of the granular body 63 of the wing portion 40 may be configured to be higher than the basis weight of the granular body 63 of the main body portion 2. The wing part 40 is fastened to the underwear by the wing adhesive region 72, and the main body part 2 is fastened to the underwear by the main body adhesive region 71. Since the area of the main body 2 is larger than the area of the wing 40, the area of the main body adhesive region 71 is generally configured to be larger than the area of the wing 40. Moreover, since the main body adhesion | attachment area | region 71 is located in the skin opposing surface side T1 rather than the underwear S and is pinched | interposed into the underwear S and a wearer, it is easy to obtain the adhesive force with respect to underwear. Since the area of the main body adhesive region 71 is relatively large and it is easy to obtain the adhesive force between the main body adhesive region 71 and the undergarment, it is easy to maintain the state where the main body portion 2 and the undergarment S are fastened. On the other hand, since the wing adhesive region 72 is located on the non-skin facing surface side T2 from the underwear S in a worn state and is not sandwiched between the underwear S and the wearer, it is relatively difficult to obtain an adhesive force to the underwear S. Since the area of the wing adhesive region 72 is relatively small and it is difficult to obtain the adhesive force between the wing adhesive region 72 and the undergarment, it may be difficult to maintain the state where the main body 2 and the undergarment S are fastened. In such a background, in order to maintain the state in which the wing part 40 and the undergarment S are fastened, it is conceivable to increase the basis weight of the adhesive in the wing adhesive region 72. However, if the basis weight of the adhesive in the wing adhesive region 72 is increased, the wing part 40 cannot be removed smoothly from the underwear S, and the wing part 40 is torn, or the adhesive in the wing adhesive region 72 remains in the underwear. Sometimes

  The absorbent article which concerns on the modification 2 has the basis weight of the granular material in the granular layer of the wing part 40 higher than the basic weight of the granular body in the granular layer of the main-body part 2, Therefore The wing part 40 is carried out by the granular body of the wing part 40. And underwear S can be brought into close contact with each other. Therefore, the fastening state of the wing part 40 and the undergarment S can be maintained without increasing the basis weight of the adhesive in the wing adhesive region 72. The fastening state of the wing part 40 and the undergarment S can be maintained while suppressing the problem that the wing part 40 is torn or the adhesive in the wing adhesive region 72 remains in the undergarment.

  Moreover, the absorbent article 1B according to the modified example 2 can also fit the absorbent article 1B to the wearer's body, particularly the excretion opening. Since the absorbent article 1B fits to the wearer's excretion opening, leakage of body fluid can be suppressed. Moreover, since the absorbent article 1B is pressed against the wearer's body by the granular layer 60, the absorbent article 1B is absorbed without being too close to the wearer's body as compared with a configuration in which the absorbent article 1B is pressed against the body with an elastic member or the like. The property article 1B can be placed, steaming and rubbing can be suppressed, and the wearing feeling can be improved.
