[0013] (Aspect 3) The absorbent pad according to aspect 1 or 2, wherein the length of the pad pattern in the width direction is shorter than the length of the diaper pattern in the width direction.

[0014] According to the third aspect, it becomes easier to align the absorbent pad with respect to the disposable diaper, and it becomes easier to place the absorbent pad on the disposable diaper and wear it.

[0015] (Aspect 4) In the absorbent pad of any one of aspects 1 to 3, the pad pattern is provided on at least one end of the absorbent pad in the front-rear direction.

[0016] According to aspect 4, it becomes easier to align the position of the absorbent pad relative to the disposable diaper, making it easier to place the absorbent pad on the disposable diaper and wear it, and even when the absorbent pad is worn alone, it becomes easier for the wearer to recognize the direction in which the absorbent pad should be placed on the wearer.

[0017] (Aspect 5) The absorbent pad of any one of aspects 1 to 4, wherein the pad pattern has a portion that continues from one end of the absorbent pad to the other end in the front-rear direction.

[0018] According to the fifth aspect, the front and rear directions of the absorbent pad relative to the wearer's body can be easily visually confirmed, making it easier to wear the absorbent pad.

[0019] (Aspect 6) In the absorbent pad according to any one of aspects 1 to 5, the pad pattern is provided at least in the center in the width direction.

[0020] According to the sixth aspect, the central portion of the absorbent pad in the width direction of the wearer's body as well as in the front-to-rear direction of the absorbent pad can be easily recognized, which makes it easier to wear the absorbent pad.

[0021] (Aspect 7) The absorbent pad of any one of aspects 1 to 6, wherein the width of the pad pattern is 0.5 mm or more and 10% or less of the maximum width of the absorbent core.

[0022] According to aspect 7, the wearer or the like can more easily see the pad pattern than when the widthwise length of the pad pattern is shorter than 0.5 mm, and is more likely to recognize it as a pattern indicating the front-to-rear position of the absorbent pad than when the widthwise length of the pad pattern is longer than 10% of the maximum widthwise length of the absorbent core.

[0023] (Aspect 8) The absorbent pad of any of aspects 1 to 7 is characterized in that the absorbent core has a low basis weight section having a basis weight lower than the surrounding area, the low basis weight section has a predetermined length in the front-to-rear direction, and the maximum length of the pad pattern in the width direction is shorter than the maximum length of the low basis weight section in the width direction.

[0024] According to aspect 8, it becomes easier for the wearer to recognize the pad pattern along the front-to-back direction and to visually confirm the front-to-back direction of the absorbent pad relative to the wearer's body, making it easier to wear the absorbent pad.

[0025] (Aspect 9) The absorbent pad of any one of aspects 1 to 8, further comprising a non-skin side pattern visible from the non-skin side, said non-skin side pattern having a predetermined length in the front-to-rear direction.

[0026] According to aspect 9, the wearer can easily recognize the direction along the front-to-back direction from the non-skin side of the absorbent pad, making it easier to don the absorbent pad and place it on a disposable diaper.

[0027] (Aspect 10) The absorbent pad according to any one of aspects 1 to 9, wherein the pad pattern is provided on the non-skin side of the skin side sheet.

[0028] According to aspect 10, it is possible to reduce the risk of colorants and the like used to create the pad pattern coming into direct contact with the wearer's skin, thereby reducing the risk of the color transferring to the wearer's skin or the risk of adversely affecting the wearer's skin.

[0029] (Aspect 11) 11. The absorbent pad according to any one of aspects 1 to 10, wherein the pad pattern is formed by a colored adhesive provided on the non-skin side of the skin side sheet.

[0030] According to aspect 11, the colored adhesive can function both as an adhesive for fixing the skin-side sheet and as a colorant for providing the pad pattern, thereby reducing the risk of a decrease in adhesive strength due to the adhesive and colorant being provided separately, while allowing the skin-side sheet to be fixed and the pad pattern to be formed in a single process, thereby simplifying the manufacturing process of the absorbent pad.

[0031] (Aspect 12) The absorbent pad of any of aspects 1 to 11 has a pair of leakproof wall portions on both sides in the width direction, each of the leakproof wall portions having a leakproof wall stretchable member that stretches in the front-to-rear direction, the color of the pad pattern and the color of the leakproof wall stretchable member are the same, and the color of the pad pattern is darker than the color of the leakproof wall stretchable member.

[0032] According to aspect 12, in addition to the pad pattern, the leakproof wall stretchable member along the front-to-back direction can be easily seen, making it easier to see the front-to-back direction of the absorbent pad relative to the wearer's body, making it easier to wear the absorbent pad.

[0033] (Aspect 13) 13. The absorbent pad according to any one of aspects 1 to 12, wherein the length of the pad pattern in the width direction is equal to or less than half the length of the diaper pattern in the width direction.

[0034] According to aspect 13, it is easier to align the position of the absorbent pad relative to the disposable diaper than when the widthwise length of the pad pattern is longer than half the widthwise length of the diaper pattern, making it easier to place the absorbent pad on the disposable diaper and wear it.

[0035] (Aspect 14) The disposable diaper is an absorbent pad according to any of aspects 1 to 13, characterized in that the disposable diaper has a pair of leakproof wall portions on both sides in the width direction, each of which has a leakproof wall sheet aligned in the front-to-rear direction and a fixing portion that fixes the leakproof wall sheet to an adjacent member in the thickness direction, and in which, when the absorbent pad and the disposable diaper are in an unfolded and extended state, the sum of the value of the width direction length of the absorbent pad at the center in the front-to-rear direction and twice the value of the maximum length of the absorbent pad in the thickness direction is smaller than the sum of the value of the distance between the inner ends of the width direction of the fixing portions at the center in the front-to-rear direction of the disposable diaper and twice the value of the length from the inner end of the fixing portion to the inner end of the leakproof wall sheet in the width direction.

[0036] According to the fourteenth aspect, when the absorbent pad is placed on the skin-facing side of the disposable diaper and worn, the absorbent pad is easily fitted inside the leakage preventing wall portion, thereby reducing the risk of the absorbent pad being misaligned. Also, even if excrement leaks outward in the width direction of the absorbent pad, the excrement is blocked by the leakage preventing wall portion of the disposable diaper, thereby reducing the risk of the excrement leaking outward from the disposable diaper and the absorbent pad.

[0037] (Aspect 15) The disposable diaper has a pair of leakproof wall portions on both sides in the width direction, each of the leakproof wall portions having a leakproof wall sheet along the front-to-rear direction and a fixing portion that fixes the leakproof wall sheet to an adjacent member in the thickness direction, the side ends of the fixing portion have straight portions along the front-to-rear direction, the absorbent pad has straight portions along the front-to-rear direction at its side ends in the width direction, and the value obtained by subtracting the value of the distance between the inner ends of the width direction of the fixing portions at the center in the front-to-rear direction of the disposable diaper in an unfolded and extended state by the value of the maximum length in the width direction of the absorbent pad at the center in the front-to-rear direction of the absorbent pad in an unfolded and extended state is 0 mm or more and 20 mm or less.

[0038] According to aspect 15, the absorbent pad can be stored along the fixed part inside the disposable diaper having a leak-proof wall part, thereby reducing the possibility of the absorbent pad shifting out of position and reducing the risk of the wearer feeling uncomfortable even when the absorbent pad is placed on the disposable diaper and worn.

[0039] (Aspect 16) The disposable diaper is an absorbent pad according to any one of aspects 1 to 15, characterized in that the disposable diaper has a pair of leakproof wall portions arranged at a predetermined interval on both sides in the width direction, each of the leakproof wall portions having a leakproof wall sheet aligned along the front-to-rear direction and a fixing portion that fixes the leakproof wall sheet to an adjacent member in the thickness direction, each of the side ends of the fixing portion having a straight portion aligned along the front-to-rear direction, the absorbent core having a straight portion aligned along the front-to-rear direction at its side end in the width direction, and the value obtained by subtracting the width direction length of the absorbent pad at the center in the front-to-rear direction of the absorbent pad in the unfolded and stretched state from the distance between the inner ends of the width direction of the fixing portions at the center in the front-to-rear direction of the disposable diaper in the unfolded and stretched state is 0 mm or more and is shorter than the length from the inner end of the fixing portion to the inner end of the leakproof wall sheet in the width direction of the disposable diaper.

[0040] According to aspect 16, the absorbent pad can be stored along the fixed portion inside the disposable diaper having a leak-proof wall portion, thereby reducing the possibility of the absorbent pad shifting out of position and reducing the risk of the wearer feeling uncomfortable even when the absorbent pad is placed on the disposable diaper and worn.

[0041] (Aspect 17) The absorbent pad of any of aspects 1 to 16 has a pair of pad leakage prevention wall portions on both sides in the width direction, each of the pad leakage prevention wall portions comprising a pad leakage prevention wall stretchable member that stretches in the front-to-rear direction, the disposable diaper has a pair of diaper leakage prevention wall portions on both sides in the width direction, each of the diaper leakage prevention wall portions comprising a diaper leakage prevention wall stretchable member that stretches in the front-to-rear direction, the pad leakage prevention wall stretchable members being colored, and the diaper leakage prevention wall stretchable members being colored.

[0042] According to aspect 17, in addition to the pad pattern and diaper pattern, the wearer can visually recognize the pad leakage prevention wall stretch member and the diaper leakage prevention wall stretch member that run along the front-to-back direction, making it easier for the wearer to visually recognize the front-to-back direction of the absorbent pad and the disposable diaper relative to the wearer's body, making it easier to don the absorbent pad.

[0043] (Aspect 18) In the absorbent pad of aspect 17, the color of the elastic member of the pad leakage preventing wall and the color of the elastic member of the diaper leakage preventing wall are the same.

[0044] According to aspect 18, in addition to the pad pattern and diaper pattern, the pad leakage prevention wall stretchable member and the diaper leakage prevention wall stretchable member along the front-to-back direction can be easily seen, making it easier to recognize the front-to-back directions of the absorbent pad and the disposable diaper relative to the wearer's body, making it easier to don the absorbent pad.

[0045] (Aspect 19) The absorbent pad of any of aspects 1 to 18 is characterized in that, on one side in the front-to-rear direction, the absorbent pad has a pad one-side fold portion closest to the center position in the front-to-rear direction and on the other side in the front-to-rear direction, the pad other-side fold portion closest to the center position in the front-to-rear direction; the disposable diaper has a diaper one-side fold portion closest to the center position in the front-to-rear direction on one side in the front-to-rear direction and a diaper other-side fold portion closest to the center position in the front-to-rear direction on the other side in the front-to-rear direction; and when the absorbent pad and the disposable diaper are overlapped so that the pad one-side fold portion and the diaper one-side fold portion overlap when viewed from the skin side, the disposable diaper has a portion where the shortest widthwise length is the portion of the disposable diaper that overlaps with the shortest widthwise length of the absorbent pad.

[0046] According to aspect 19, when the front-to-back direction of the absorbent pad and the front-to-back direction of the disposable diaper are correctly combined, the wearer is less likely to feel uncomfortable, making it easier for the wearer to recognize the correct orientation of the absorbent pad and disposable diaper when worn.

[0047] (Aspect 20) The absorbent pad of any of aspects 1 to 19 is characterized in that, on one side in the front-to-rear direction, the absorbent pad has a pad one-side fold portion closest to the center position in the front-to-rear direction, and on the other side in the front-to-rear direction, the pad other-side fold portion closest to the center position in the front-to-rear direction; and the disposable diaper has a diaper one-side fold portion closest to the center position in the front-to-rear direction, and a diaper other-side fold portion closest to the center position in the front-to-rear direction, on one side in the front-to-rear direction, and when the absorbent pad and the disposable diaper are overlapped so that the pad one-side fold portion and the diaper other-side fold portion overlap when viewed from the skin side, the disposable diaper has a portion where the portion of the disposable diaper that has the shortest length in the width direction overlaps with the portion of the absorbent pad that has the longest length in the width direction.

[0048] According to aspect 20, if the absorbent pad and the disposable diaper are worn with the front-to-back direction incorrect, it is likely to cause discomfort to the wearer, so it is made easier for the wearer to recognize the correct wearing orientation of the absorbent pad and the disposable diaper.

[0049] (Aspect 21) The absorbent pad of any of aspects 1 to 20 is characterized in that the diaper pattern is provided at one end of the disposable diaper in the front-to-rear direction, and a central portion of the diaper pattern is provided between the side ends in the width direction of the diaper pattern at one end of the front-to-rear direction of the disposable diaper and has a color different from that of the side ends, the color of the pad pattern is different from the color of the central portion of the diaper pattern, and the width direction length of the pad pattern at one end of the absorbent pad in the front-to-rear direction is shorter than the width direction length of the central portion of the diaper pattern.

[0050] According to aspect 21, it becomes easier for the wearer to recognize the pad pattern in relation to the diaper pattern, thereby making it easier to visually distinguish between the absorbent pad and the disposable diaper and to align the absorbent pad in relation to the disposable diaper, thereby making it easier to place the absorbent pad on the disposable diaper and wear it.

[0051] (Aspect 21) A group of absorbent articles comprising an absorbent pad package in which an absorbent pad is contained in a pad container, and a disposable diaper package in which a disposable diaper is contained in a diaper container, wherein the absorbent pad and the disposable diaper have front-to-rear, width and thickness directions which are perpendicular to each other when in an unfolded state, the absorbent pad has an absorbent core and a skin side sheet having a portion that is closer to the skin than the absorbent core, and has a pad pattern visible from the skin side, the pad pattern having a predetermined length in the front-to-rear direction, the disposable diaper has a diaper pattern visible from the skin side, the diaper pattern having a predetermined length in the front-to-rear direction, and the width direction length of the pad pattern and the width direction length of the diaper pattern are different.

[0052] According to aspect 21, when the absorbent pad is placed on a disposable diaper and worn, the widthwise length of the pad pattern is different from the widthwise length of the diaper pattern, making it easier to align the absorbent pad with the disposable diaper while visually distinguishing the absorbent pad from the disposable diaper, thereby making it easier to place the absorbent pad on the disposable diaper and wear it.

[0053] (Aspect 22) A method for manufacturing absorbent articles, which manufactures an absorbent pad having an absorbent core and a skin-side sheet with a portion that is located closer to the skin than the absorbent core and which has front-to-back, width and thickness directions that are perpendicular to each other in an unfolded state, and a disposable diaper having front-to-back, width and thickness directions that are perpendicular to each other in an unfolded state, the method comprising the steps of providing the absorbent pad with a pad pattern that is visible from the skin side, and providing the disposable diaper with a diaper pattern that is visible from the skin side, wherein the pad pattern has a predetermined length in the front-to-back direction of the absorbent pad, the diaper pattern is provided to have a predetermined length in the front-to-back direction of the disposable diaper, and the width direction length of the pad pattern and the width direction length of the diaper pattern are different.

[0054] According to aspect 22, when the absorbent pad is placed on a disposable diaper and worn, the widthwise length of the pad pattern is different from the widthwise length of the diaper pattern, making it easier to align the absorbent pad with the disposable diaper while visually distinguishing between the absorbent pad and the disposable diaper, thereby making it easier to place the absorbent pad on the disposable diaper and wear it.

[0055] === Implementation form === Hereinafter, an embodiment will be described taking an absorbent pad (urine pad) for adults as an example of an absorbent article. However, the absorbent article is not limited to the above, and may be, for example, a tape-type disposable diaper, a pants-type disposable diaper, a sanitary napkin, a panty liner, a shorts-type napkin, a light incontinence pad, etc. Furthermore, the wearer of the absorbent article is not limited to adults, but may also be a child or a pet. Furthermore, hereinafter, a wearer of the absorbent article (urine pad 1) or a person who intends to have a wearer wear the absorbent article is also referred to as a "wearer, etc." or a "user."

[0056] The absorbent article of the present invention can be used as a single absorbent article, or as a combination of multiple absorbent articles. By using multiple absorbent articles in combination, it is possible to easily suppress leakage of excrement and to simplify excrement processing by reducing the number of times the absorbent articles need to be replaced. For example, an absorbent pad such as a urine absorption pad can be placed on the skin side of a pants-type disposable diaper or a tape-type disposable diaper. Hereinafter, an embodiment in which an absorbent pad 1 (hereinafter also referred to as "pad 1") is placed on the skin side of a tape-type disposable diaper 101 (hereinafter also referred to as "diaper 101") will be described.

[0057] The developed state of the pad 1 and the diaper 101 refers to a state in which the entire pad 1 and the diaper 101 are developed in a plane, and all fold lines (folded parts) are developed. When the absorbent article is a pants-type (shorts-type) absorbent article, the developed state refers to a state in which the side joint parts provided on both sides of the absorbent article are separated and the absorbent article is opened and developed in a plane. The stretched state of the pad 1 and the diaper 101 refers to a state in which the pad 1 and the diaper 101 are stretched to such an extent that wrinkles that have occurred in the pad 1 and the diaper 101 are substantially invisible, and refers to a state in which the pad 1 and the diaper 101 are stretched to such an extent that the dimensions of each member (e.g., the side sheet 5 described later) constituting the pad 1 and the diaper 101 match or are close to the dimensions of the member alone.

[0058] In the developed state, the pad 1 and the diaper 101 have a front-rear direction, a width direction, and a thickness direction that are mutually orthogonal. Specifically, the pad 1 has a front-rear direction, a width direction, and a thickness direction that are mutually orthogonal, and the diaper 101 has a front-rear direction, a width direction, and a thickness direction that are mutually orthogonal. When the pad 1 and the diaper 101 are used together, that is, when the pad 1 is used with the diaper 101 placed on the skin side, the front-rear direction of the pad 1 and the front-rear direction of the diaper 101 are aligned, the width direction of the pad 1 and the width direction of the diaper 101 are aligned, and the thickness direction of the pad 1 and the thickness direction of the diaper 101 are aligned. The front-rear direction of the pad 1 and the diaper 101 corresponds to the longitudinal direction of the absorber 10 and the absorber 110 described later. The front side of the pad 1 and the diaper 101 in the front-rear direction corresponds to the abdominal side of the wearer when worn, and the rear side corresponds to the back side of the wearer. In addition, in the thickness direction of the pad 1 and the diaper 101, the side that comes into contact with the wearer's skin is referred to as the skin side, and the opposite side is referred to as the non-skin side.

[0059] <<Basic configuration of absorbent pad 1>> Fig. 1 is a plan view of the absorbent pad 1 in an unfolded and stretched state, as viewed from the skin side. Fig. 2 is a plan view of the absorbent pad 1 in an unfolded and stretched state, as viewed from the non-skin side. Fig. 3 is a schematic cross-sectional view taken along the line II in Fig. 1. The center line C1-C1 shown in Fig. 1 etc. indicates the center of the pad 1 in the width direction, and the center line CL1 indicates the center of the pad 1 in the front-rear direction in the unfolded state. Some components such as adhesives are omitted in Fig. 3 etc.

[0060] The part between both ends of the pad 1 in the front-rear direction, which has the shortest length in the width direction of the pad 1, and which is located under the crotch of the wearer when worn is also referred to as the "crotch part 1m". The crotch part 1m may be, but is not limited to, the central part obtained by dividing the pad 1 into thirds in the front-rear direction. For example, the length of the crotch part 1m in the front-rear direction may be shorter or longer than the length obtained by dividing the pad 1 into thirds in the front-rear direction, and in a pad that extends farther to the rear, the crotch part 1m may be located toward the front.

[0061] As shown in Figures 1 to 3, the pad 1 has an absorbent body 10, a liquid-permeable surface sheet 2 (e.g., a nonwoven fabric or a perforated film) provided on the skin side of the absorbent body 10, a liquid-impermeable or liquid-difficult-to-permeable back sheet 3 (e.g., a resin film) provided on the non-skin side of the absorbent body 10, an exterior sheet 4 (e.g., a nonwoven fabric) provided on the non-skin side of the back sheet 3, and a pair of side sheets 5 (e.g., a hydrophobic nonwoven fabric) provided on both sides of the surface sheet 2 in the width direction.

[0062] The absorbent body 10 has an absorbent core 11 and a core wrap sheet 12. The absorbent core 11 has a two-layer structure, and has an upper absorbent core 11a provided on the skin side and a lower absorbent core 11b provided on the non-skin side. Examples of the upper absorbent core 11a and the lower absorbent core 11b include liquid-absorbent fibers such as pulp fibers containing SAP (super absorbent polymer) molded into a predetermined shape. The core wrap sheet 12 has an upper core wrap sheet 12a that covers the skin side of the upper absorbent core 11a, and a lower core wrap sheet 12b that wraps the skin side and non-skin side of the lower absorbent core 11b. Examples of the core wrap sheet 12 include liquid-permeable tissue and nonwoven fabric.

[0063] The upper absorbent core 11a and the lower absorbent core 11b have slits 11as, 11bs that extend in the front-to-rear direction and penetrate in the thickness direction at the center of the width of the crotch portion 1m. The slits 11as, 11bs become folding starting points, and the upper absorbent core 11a and the lower absorbent core 11b are easily deformed to encase the crotch of the wearer.

[0064] However, the configuration of the absorbent body 10 is not limited to the above. For example, the absorbent core may be composed of one layer, may not have the slits 11as, 11bs, and may not be covered with the core wrap sheet 12. Instead of the slits 11as, 11bs, a low basis weight portion in which the liquid absorbent fiber has a low basis weight, or a compressed portion in which the liquid absorbent fiber is compressed in the thickness direction may be provided. The absorbent core may be an SAP sheet in which an SAP layer is attached to a hydrophilic sheet, or an airlaid sheet in which liquid absorbent fiber is formed into a sheet shape by an airlaid method. The upper absorbent core 11a and the lower absorbent core 11b may each be made of different absorbent materials.

[0065] The pad 1 also has a pair of leak-preventing walls 6 that can stand up on the skin side on both sides in the width direction. The leak-preventing walls 6 are formed of a side sheet 5 and a leak-preventing wall elastic member (leak-preventing wall stretchable member) 7 such as rubber thread. The leak-preventing wall elastic member 7 is fixed in a stretched state along the front-rear direction to the folded-back portion of the inner end of the side sheet 5 in the width direction.

[0066] FIG. 4 is a diagram illustrating the leak-preventing wall 6. The pad 1 has a leak-preventing wall 6 that can stand up on the skin side at the side in the width direction. The leak-preventing wall 6 is formed by a side sheet (leak-preventing wall sheet) 5 and a leak-preventing wall elastic member 7. The side sheet 5 is fixed to the top sheet 2 by an adhesive region A1 from one end to the other end along the front-rear direction, and both ends in the front-rear direction are fixed to the top sheet 2 by an adhesive region A2 on the inside of the adhesive region A1 in the width direction. The adhesive region A1 and the adhesive region A2 are the fixing portion that fixes the side sheet 5 to the top sheet 2 (a member adjacent to the side sheet 5 in the thickness direction). By this fixing, the part of the side sheet 5 inside the adhesive regions A1 and A2 stands up on the skin side as the leak-preventing wall 6 due to contraction of the leak-preventing wall elastic member 7. Therefore, the inside end in the width direction of the adhesive region A1 becomes the rising starting point 6s of the leak-preventing wall 6 in the width direction.

[0067] <<Basic structure of tape-type disposable diapers 101>> Fig. 5 is a plan view of the diaper 101 in an unfolded and stretched state, as viewed from the skin side. Fig. 6 is a plan view of the diaper 101 in an unfolded and stretched state, as viewed from the non-skin side. Fig. 7 is a schematic cross-sectional view taken along the line AA in Fig. 5. The center line C2-C2 shown in Fig. 5 etc. indicates the center of the diaper 101 in the width direction, and the center line CL2 indicates the center of the diaper 101 in the front-rear direction in the unfolded state. Some components such as adhesives are omitted in Fig. 7 etc.

[0068] The diaper 101 has a main body portion 100A and a pair of fastening tape portions 100B. As shown in FIG. 5, the main body portion 100A is a belt-shaped member located in the center in the width direction, and has a front portion X, a crotch portion Y, and a rear portion Z. The front portion X is a portion that will be located in front of the wearer (abdominal side). The rear portion Z is a portion that will be located in the rear of the wearer (buttocks side, back side). The crotch portion Y is a portion that will be located between the front portion X and the rear portion Z, and is a portion that has the shortest length in the width direction of the diaper 101.

[0069] As shown in FIGS. 5 to 7, the diaper 101 includes an absorber 110, a liquid-permeable surface sheet 102 (such as a non-woven fabric or a perforated film) provided closer to the skin side than the absorber 110, a liquid-impermeable or liquid-hardly-permeable back sheet 103 (such as a resin film) provided closer to the non-skin side than the absorber 110, an outer cover sheet 104 (such as a non-woven fabric) provided closer to the non-skin side than the back sheet 103, and a pair of side sheets 105 (such as a hydrophobic non-woven fabric) provided on both side portions in the width direction of the surface sheet 102. Further, a member that expands and contracts in the front-rear direction or the width direction may be provided as appropriate.

[0070] The absorber 110 has an absorbent core 111 and a core wrap sheet 112. The absorbent core 111 has a two-layer structure and includes an upper absorbent core 111a provided on the skin side and a lower absorbent core 111b provided on the non-skin side. Examples of the upper absorbent core 111a and the lower absorbent core 111b include those in which liquid-absorbent fibers such as pulp fibers containing SAP (superabsorbent polymer) are formed into a predetermined shape. The core wrap sheet 112 has an upper core wrap sheet 112a that covers the skin side surface and the non-skin side surface of the upper absorbent core 11a and a lower core wrap sheet 112b that wraps the skin side surface and the non-skin side surface of the lower absorbent core 11b. Examples of the core wrap sheet 112 include a liquid-permeable tissue, a non-woven fabric, and the like.

[0071] Further, the lower absorbent core 111b has slits 111bs that extend along the front-rear direction and penetrate in the thickness direction. The slits 111bs serve as folding starting points, and the absorbent core 111 is easily deformed according to the wearer's body and movement.

[0072] However, the configuration of the absorbent body 110 is not limited to the above. For example, the absorbent core may be composed of one layer, may not have the slits 111bs, and the absorbent core 111 may not be covered with the core wrap sheet 112. Instead of the slits 111bs, a low basis weight portion in which the basis weight of the liquid absorbent fiber is low, or a compressed portion in which the liquid absorbent fiber is compressed in the thickness direction may be provided. The absorbent core may also be an SAP sheet in which an SAP layer is attached to a hydrophilic sheet, or an airlaid sheet in which liquid absorbent fiber is formed into a sheet shape by an airlaid method. The upper layer absorbent core 111a and the lower layer absorbent core 111b may each be made of different absorbent materials.

[0073] The diaper 101 has a pair of leak-proof walls 106 that can stand up against the skin on both sides in the width direction. The leak-proof walls 106 are formed by a side sheet 105 and a leak-proof wall elastic member (leak-proof wall stretchable member) 107 such as rubber thread. The leak-proof wall elastic member 107 is fixed in a stretched state along the front-rear direction to the folded-back portion of the inner end of the side sheet 105 in the width direction.

[0074] 8 is a diagram illustrating the leak-proof wall 106. The diaper 101 has a leak-proof wall 106 that can stand up on the skin side at the side in the width direction. The leak-proof wall 106 is formed by a side sheet (leak-proof wall sheet) 105 and a leak-proof wall elastic member 107. The side sheet 105 is fixed to the top sheet 102 (a member adjacent to the side sheet 105 in the thickness direction) by an adhesive region A101 from one end to the other end along the front-rear direction, and both ends in the front-rear direction are fixed to the top sheet 102 by an adhesive region A102 on the inner side in the width direction from the adhesive region A101. The adhesive regions A101 and A102 are fixing parts that fix the side sheet 105 to the top sheet 102. By this fixing, the part of the side sheet 105 inside the adhesive regions A101, A102 stands up towards the skin as the leakage preventing wall portion 106 due to contraction of the leakage preventing wall elastic member 107. Therefore, the inner end in the width direction of the adhesive region A101 becomes the standing starting point 106s of the leakage preventing wall portion 106 in the width direction.

[0075] The fastening tape section 100B is joined to the main body section 100A and is formed to protrude outward in the width direction. The fastening tape section 100B includes a side flap sheet b1, which is a sheet member such as a nonwoven fabric, and an engagement section b2 at the tip of the side flap sheet b1. The engagement section b2 is a member provided on the skin side of the side flap sheet b1, facing the non-skin side of the front section X, and removably engaging with the non-skin side of the front section X. An example of the engagement section b2 is a male member of a hook-and-loop fastener having a protrusion (hook member) that hooks onto the fibers that make up the exterior sheet 104. Note that a member (for example, a target area of ​​a female member of the hook-and-loop fastener) that easily engages with the engagement section b2 may be provided on the non-skin side of the exterior sheet 104. The fastening tape section 100B may also include an elastic member that expands and contracts in the width direction between the part that fixes the side flap sheet b1 to the main body section 100A and the engagement section b2.

[0076] <<About absorbent products>> The group of absorbent articles includes a package 50 of pads 1 and a package 500 of diapers 101. In other words, the group of absorbent articles is made up of a plurality of packages of absorbent articles, and in this embodiment, is made up of packages 50 and 500.

[0077] 9A is a perspective view of a pad package 50. The pad package 50 is a package in which one or more of the above-mentioned pads 1 are accommodated in a pad accommodation member 51. In this embodiment, a plurality of pads 1 are accommodated in the pad accommodation member 51. The pad 1 in the package 50 is accommodated in a folded state at one or more fold portions F1. Note that the pad 1 may have a configuration that does not include the fold portion F1. 9B is a perspective view of a diaper package 500. The diaper package 500 is a package in which one or more of the above-mentioned diapers 101 are accommodated in a diaper accommodation member 501. In this embodiment, a plurality of diapers 101 are accommodated in the diaper accommodation member 501. The diapers 101 in the package 500 are accommodated in a folded state at one or more fold portions F10. The diapers 101 may be configured not to have the fold portion F10.

[0078] The pad 1 and the diaper 101 are distributed, sold, stored, etc., in a state where they are housed in a pad housing member 51 and a diaper housing member 501, respectively (hereinafter also referred to as a "housed state"), and hygiene is ensured. The pad package 50 and the diaper package 500 constituting the absorbent article group of this embodiment are products that can be sold and distributed separately. For example, the absorbent article group may be constituted by the pad package 50 and a package (not shown) that houses a pants-type diaper different from the diaper package 500.

[0079] In the group of absorbent articles of the present embodiment, the pad package 50 and the diaper package 500 are in a form that can be sold as products in different packages, but the present invention is not limited to this. For example, the group of absorbent articles may be in the form of a package of absorbent articles in which one or more pad packages 50 and one or more diaper packages 500 are contained in one container, or one or more pads 1 and one or more diapers 101 are contained in one container without being contained in a container (pad container, diaper container).

[0080] Although the basic configurations of the pad 1 and the diaper 101 have been described above, the configurations of the pad 1 and the diaper 101 described above are merely examples and are not intended to be limiting. For example, the pad, the diaper, etc. may not have the leakage preventing walls 6, 106, etc.

[0081] ===About wearing Pad1 and Diaper101=== The pad 1 taken out of the package 50 and the diaper 101 taken out of the package 500 can be used by first unfolding them from the folded state at the folds F1 and F10 and placing the pad 1 on the skin side of the diaper 1. Fig. 10 is a diagram illustrating the state in which the pad 1 is placed on the skin side of the diaper 101. For convenience, Fig. 10 shows the pad 1 and the diaper 101 in an unfolded and extended state.

[0082] In order to reduce the number of times an absorbent article is changed or the effort required for changing the absorbent article, or to further suppress leakage of excrement, the pad 1 may be placed on the skin side of the diaper 101 when worn. When placing the pad 1 on the skin side of the diaper 101, there is a problem that it is difficult for the wearer to recognize the position of the pad 1 relative to the diaper 101. For example, if the wearer does not correctly recognize the position of the pad 1 relative to the diaper 101, the pad 1 may be placed on the diaper 101 with the front-to-back direction of the pad 1 tilted relative to the front-to-back direction of the diaper 101.

[0083] In contrast, in the present invention, the pad 1 has a pad design 8 and the diaper 101 has a diaper design 108. As shown in Figs. 1 and 10, the pad pattern 8 is visible from the skin side and is a line-shaped pattern having a predetermined length in the front-rear direction. As shown in Figs. 5 and 10, the diaper design 108 is visible from the skin side and is a graphic of two lines having a predetermined length in the front-rear direction. As shown in FIG. 10, the maximum widthwise length d8 of the pad pattern 8 is different from the maximum widthwise length d108 of the diaper pattern 108 (d8≠d108).

[0084] As a result, when the pad 1 is placed on the skin side of the diaper 1 and worn, the maximum widthwise length d8 of the pad pattern 8 on the pad 1 is different from the widthwise length d108 of the diaper pattern 108 on the diaper 101, making it easier to visually distinguish the pad 1 from the diaper 101. In addition, the pad pattern 8 and the diaper pattern 108 are visible from the skin side and aligned in the front-to-back direction, respectively, and therefore make it easier for the wearer to recognize the front-to-back direction of the pad 1 and the front-to-back direction of the diaper 101 when worn, as seen from the skin side, making it easier to align the position of the pad 1 with respect to the diaper 101. Furthermore, the pad pattern 8 and the diaper pattern 108 are aligned in the front-to-back direction, respectively, making it easier for the wearer to recognize the front-to-back direction of the pad 1 and the diaper 101 with respect to the wearer's body. This makes it easier for the wearer to place the pad on the diaper 101 and wear it.

[0085] The pad 1 may be used alone without being placed on the diaper 101. By providing the pad 1 with a pad pattern 8 along the front-rear direction that is visible from the skin side when viewed from the skin side, for example, when a caregiver or the like places the pad 1 under the buttocks of a lying wearer, the caregiver can recognize the front-rear direction of the pad 1 relative to the wearer's body by visually checking the pad pattern 8 along the front-rear direction, making it easier to don the pad 1. In this case, it is preferable that the pad pattern 8 is provided in at least a part of the overlapping region that overlaps with the absorbent core 11 when viewed from the skin side of the pad 1.

[0086] The pad design 8 and the diaper design 108 may be continuous in the front-rear or width direction, or may be discontinuous. The diaper design 108 of the diaper 101 is composed of multiple (two) linear figures spaced apart in the width direction. Specifically, the diaper design 108 of the diaper 101 has lines 108a, 108a which are linear figures at the side ends in the width direction. The lines 108a, 108a are areas which can be visually recognized as areas colored blue from the skin side. An uncolored central portion (diaper design central portion) 108b is provided between both blue side portions (lines 108a). The central portion 108b is an area where the white color of the skin side sheet 102 can be visually recognized because it is not colored. In this way, when the pad design 8 or the diaper design 108 is composed of a plurality of figures, the pad design 8 and the diaper design 108 are each an area surrounded by the outermost edges of the plurality of figures. In this embodiment, the diaper design 108 is composed of two linear figures, the length in the front-rear direction of the diaper design 108 is the length from the front end to the rear end of the diaper 101, the length in the width direction of the diaper design 108 is the length from the side end of one side located on the most one side in the width direction among the plurality of figures to the side end of the other side located on the most other side in the width direction, and the outline of the diaper design 108 refers to the area surrounded by the front end and rear end of the diaper 108, one side end of the linear figures on one side in the width direction, and the other side end of the linear figures on the other side in the width direction. In the diaper pattern 108 of this embodiment, for two line-shaped figures, the length from one end of the line-shaped figure located on one side in the width direction to the other end of the line-shaped figure located on the other side in the width direction is defined as the widthwise length d108 of the diaper pattern 108.

[0087] Regarding the pad pattern 8 and the diaper pattern 108, as in the present embodiment, it is preferable that the maximum length d8 in the width direction of the pad pattern 8 is shorter than the maximum length d108 in the width direction of the diaper pattern 108 (d8 < d108). As shown in FIG. 10, in the width direction, the length in the width direction of the pad pattern 8 of the pad 1 on the mounting side is shorter than the length in the width direction of the diaper pattern 108 of the diaper 108 on the mounted side. Thus, the wearer or the like is less likely to have the impression that the position of the pad 1 with respect to the diaper 101 must be strictly aligned than when the length in the direction of the pad pattern 8 is longer than the length in the width direction of the diaper pattern 108. For example, it is easy to give the impression that a rough alignment such as placing the pad pattern 8 inside the diaper pattern 108 in the width direction is sufficient. Therefore, it becomes easier to align the position of the pad 1 with respect to the diaper 101. As a result, it becomes easier for the wearer or the like to place and wear the pad 1 on the diaper 101.

[0088] Furthermore, it is more preferable that the length d8 in the width direction of the pad pattern 8 is less than or equal to half of the length d108 in the width direction of the diaper pattern 108 (d8 ≤ d108 × 1 / 2). By providing the pad 1 with such a pad pattern 8, the impression that the position of the pad 1 with respect to the diaper 101 must be strictly aligned is less likely to be given than when the length d8 in the width direction of the pad pattern 8 is longer than half of the length d108 in the width direction of the diaper pattern 108, and it becomes easier to align the position of the pad 1 with respect to the diaper 101. As a result, it becomes easier for the wearer or the like to place and wear the pad 1 on the diaper 101.

[0089] The pad pattern 8 is preferably provided on the non-skin side of the skin side of the skin side sheet located closer to the skin than the absorbent core 11 while being visible from the skin side. The pad 1 of this embodiment is provided on the non-skin side of the top sheet 2 located closer to the skin than the absorbent core 11. The pad pattern 8 provided on the non-skin side of the top sheet 2 is visible from the skin side of the pad 1 through the top sheet 2. This reduces the risk that a coloring agent or the like for providing the pad pattern 8 will come into direct contact with the wearer's skin. This reduces the risk that the color will adhere to the wearer's skin or that it will have an adverse effect such as irritating the wearer's skin.

[0090] Furthermore, it is more preferable that the pad pattern 8 is formed by a colored adhesive (hot melt adhesive) provided on the non-skin side of the top sheet (skin side sheet) 2. In the manufacturing process of the pad 1, a colored hot melt adhesive colored in a color (e.g., blue) different from the color of the top sheet 2 (e.g., white) is applied to the non-skin side of the top sheet 2 along the front-rear direction. By doing so, the pad pattern 8 can be formed, and the adhesive for joining the top sheet 2 and the absorbent 10 can also serve as a coloring agent for forming the pad pattern 8, so that the manufacturing process can be simplified. In addition, if the adhesive for fixing the top sheet 2 and the coloring agent for forming the pad pattern 8 are provided separately, there is a risk that the adhesive and the coloring agent will mix and reduce the adhesive strength, but by having the adhesive for fixing the top sheet 2 also serve as a coloring agent for forming the pad pattern 8, the risk of a decrease in adhesive strength can be reduced. Furthermore, since the colored hot melt adhesive does not directly contact the wearer's skin, it is possible to prevent the wearer's skin from being irritated.

[0091] "Colored" refers to a color other than colorless, transparent, and white. On the other hand, "white" refers to, for example, a color expressed as "N9.5" in the Munsell color system, a color expressed as "255,255,255" in the RGB color space (so-called pure white), and a color whose color difference from pure white is less than 12 are also included in white. For measuring the color difference of white, for example, a color difference measuring instrument such as a CR-300 manufactured by Konica Minolta can be used, and the light source of the measuring instrument can be C light source (standard of the International Commission on Illumination (CIE)). In this case, the diameter of the measuring window of the measuring instrument is 40 mm. The color difference is ΔL, Δa, and Δb in the (L*a*b*) color space relative to a white reference plate. The color difference relative to the white reference plate can be calculated by measuring the lab value of the white reference plate and the lab value of the target sample, respectively. The white reference plate is set to lab0 at (X93.19, Y95.20, Z112.28). Here, L is a value that indexes brightness, and a and b are plane coordinates of chromaticity. If the Lab values ​​of the white reference plate are L0, a0, and b0, and those of the target sample are L1, a1, and b1, then ΔL=L0-L1, Δa=a0-a1, and Δb=b0-b1 can be calculated.

[0092] On the other hand, the diaper pattern 108 of the diaper 101 of this embodiment is formed on either the back sheet 3 or the exterior sheet 4 by a coloring agent or the like. The diaper pattern 108 provided on either the back sheet 3 or the exterior sheet 4 is visible from the skin side of the diaper 101 through the top sheet 2 at a portion that does not overlap with the absorbent core 11 when viewed from the skin side. In other words, the diaper pattern 108 along the front-to-rear direction is visible at least at the front end and rear end of the diaper 101. The diaper pattern 108 is not limited to being provided on the back sheet 3 or the exterior sheet 4. As with the pad 1, the diaper pattern 108 may be provided on the non-skin side of the top sheet 102 relative to the skin side, or on the skin side of the top sheet 102.

[0093] The pad design 8 and the diaper design 108 can be provided by well-known methods respectively. Not limited to the colored adhesives and colorants such as printing exemplified above, the pad design 8 and the diaper design 108 may be colored sheet members such as film sheets of a color different from that of the members constituting the pad 1 and the diaper 101 such as the surface sheets 2 and 102, or the pad design 8 and the diaper design 108 may be provided by a squeezing portion or the like.

[0094] FIG. 10 shows a view of the pad 1 and the diaper 101 as seen from the skin side with the pad 1 overlapped on the diaper 101 such that the center in the width direction of the pad 1 overlaps with the center in the width direction of the diaper 101. In this case, at least a part of the pad design 8 and at least a part of the diaper design 108 are respectively visible, and preferably, in the width direction, there is a portion where the pad design 8 and the diaper design 108 overlap. As shown in FIG. 10, as seen from the skin side, the pad design 8 is visible over the entire region in the front-rear direction of the pad 1, and the diaper design 108 is visible at the front end portion and the rear end portion of the diaper 101. And, in the width direction, there is a portion where the pad design 8 and the diaper design 108 overlap, specifically, in a state of being contained inside the diaper design 108. Thereby, when wearing, as seen from the skin side, it becomes easier for the wearer or the like to recognize the front-rear direction of the pad 1 and the front-rear direction of the diaper 101, so that it becomes easier to align the position of the pad 1 with respect to the diaper 101. Therefore, it becomes easy for the wearer or the like to place the pad on the diaper 101 and wear it.

[0095] The pad design 8 is preferably provided at an end portion on at least one side in the front-rear direction of the pad 1. Thereby, when wearing, as seen from the skin side, it becomes easier to align the position of the pad 1 with respect to the diaper 101, and it becomes easy to place the pad 1 on the diaper 101 and wear it. Also, even in the case of wearing the pad 1 alone without placing it on the diaper 101, since it becomes easier for the wearer or the like to recognize the direction in which the pad 1 is applied (laid) to the wearer, the attachment of the pad 1 becomes easy.

[0096] In addition, the pad pattern 8 does not have to be a continuous straight line as long as it extends in the front-rear direction, and may be a wavy line, a dashed line, a specific figure, etc. Also, the figures constituting the pad pattern 8 may be intermittently arranged in the front-rear direction and the width direction.

[0097] It is preferable that the pad pattern 8 has a portion that continues from one end to the other end in the front-to-rear direction of the pad 1. In this embodiment, the pad pattern 8 in the form of a line continues from the front end to the bottom end of the pad 1. This makes it easier to visually confirm the front-to-rear direction of the pad 1 relative to the wearer's body, and makes it easier to recognize the front-to-rear direction of the pad 1 relative to the front-to-rear direction of the diaper 101. This makes it easier to wear the pad 1.

[0098] The pad pattern 8 of the pad 1 is preferably provided at least in the center in the width direction of the pad 1. This makes it easier to recognize the center in the width direction of the pad 1 in addition to the front-rear direction of the pad 1 along the front-rear direction with respect to the wearer's body and the front-rear direction with respect to the diaper 101, making it easier to wear the pad 1.

[0099] Regarding the pad pattern 8, it is preferable that the maximum widthwise length d8 of the pad pattern 8 is 0.5 mm or more and 10% or less of the maximum widthwise length L11 of the absorbent core 11 (0.5 mm≦d8≦L11×10%). When the maximum widthwise length d8 of the pad pattern 8 is 0.5 mm or more, the wearer can easily visually recognize the pad pattern 8 compared to when the maximum widthwise length d8 of the pad pattern 8 is shorter than 0.5 mm. In addition, when the maximum widthwise length d8 of the pad pattern 8 is 10% or less of the maximum widthwise length L11 of the absorbent core 11, the wearer can easily recognize the pad pattern 8 as a pattern for indicating the front-rear position in the pad 1 compared to when the maximum widthwise length d8 of the pad pattern 8 is longer than 10% of the maximum widthwise length L11 of the absorbent core 11.

[0100] Further, when the absorbent core 11 has a low basis weight portion with a basis weight lower than the surroundings and the low basis weight portion has a predetermined length in the front-rear direction, it is preferable that the maximum length d8 in the width direction of the pad pattern 8 is shorter than the maximum length in the width direction of the low basis weight portion. In the present embodiment, the absorbent core 11 of the pad 1 has slits 11as and 11bs penetrating in the thickness direction. Since the basis weight of these slits 11as and 11bs is 0, they are low basis weight portions in the absorbent core 11 where the basis weight is lower than the surroundings. As shown in FIG. 10, the maximum length d8 in the width direction of the pad pattern 8 is shorter than the maximum length d11s in the width direction of the slit (d8 < d11s). Even in such a pad 1, the wearer or the like can easily recognize the pad pattern 8 along the front-rear direction, and it becomes easier to recognize the front-rear direction of the pad 1 with respect to the wearer's body and the front-rear direction of the pad 1 with respect to the front-rear direction of the diaper 101, so that the pad 1 can be easily worn.

[0101] The pad 1 preferably has not only a pad pattern 8 visible from the skin side but also a non-skin side pattern 9 visible from the non-skin side. The non-skin side pattern 9 preferably has a predetermined length in the front-rear direction. As shown in FIG. 2, the pad 1 of the present embodiment includes a non-skin side pattern 9 visible from the non-skin side. In the non-skin side pattern 9, a plurality of circles are intermittently arranged in the front-rear direction, so that as a whole pattern, it has a pattern having a predetermined length along the front-rear direction. Thereby, the wearer or the like can easily recognize the direction along the front-rear direction of the pad 1 not only from the skin side surface of the pad but also from the non-skin side surface, so that it becomes easier to wear the pad 1 alone or to place the pad 1 on the diaper 10.

[0102] Further, it is preferable that the pad 1 has a pair of leak-proof wall portions 6 on both sides in the width direction, and each of the leak-proof wall portions 6 includes a leak-proof wall elastic member 7 that expands and contracts in the front-rear direction. The color of the pad pattern 8 and the color of the leak-proof wall elastic member 7 are the same color, and it is more preferable that the color of the pad pattern 8 is darker than the color of the leak-proof wall elastic member 7. Thereby, the wearer or the like can easily visually recognize the leak-proof wall elastic member 7 of the leak-proof wall portion 6 along the front-rear direction in addition to the pad pattern 8, and it becomes easier to recognize the front-rear direction of the pad 1 with respect to the wearer's body and the front-rear direction of the pad 1 with respect to the diaper 101, so that the pad 1 can be easily worn.

[0103] Whether or not they are "the same color" can be determined as long as the user can judge them to be the same color when visually checking the pad design 8 and the leakproof wall elastic member 7. Specifically, this can be determined by whether the color difference when measured using a Konica Minolta color difference meter CR-300 or an equivalent device is less than 13, or whether the deviation in the 24-color color chart classified by the Ostwald color wheel is 1 or less. Colors that are not "the same color" are considered to be "different colors."

[0104] As for the pad design 8 and the diaper design 108, as shown in Fig. 12 etc., it is preferable that the diaper design 108 is provided at the end of the front side (one side) of the diaper 101, and that a central portion (diaper design central portion) 108b having a different color from the side ends 108a is provided between the side ends 108a in the width direction of the diaper design 108 at the front end of the diaper 101. In such a case, it is preferable that the color of the pad design 8 is different from the color of the central portion 108b, and it is more preferable that the width direction length d8 of the pad design 1 at the front end of the pad 1 is shorter than the width direction length of the central portion 108b. This makes it easier for the wearer to recognize the pad design 108 relative to the diaper design 1. In particular, when the pad 1 is placed on the skin side of the diaper 101 so that the center of the width of the diaper pattern 8 and the center of the width of the central portion 108b overlap when viewed from the skin side, the pad pattern 8 is placed so as to be contained inside the central portion 108b of the diaper pattern 108 in the width direction, so that the boundary between the side end portion 108a and the central portion 108b of the diaper pattern 108 and the boundary between the central portion 108b and the pad pattern 8 can be visually recognized, and the boundary between the side end portion 108a and the central portion 108b of the diaper pattern 108 and the pad pattern 8 can be easily recognized by the boundary of different colors. Then, since it becomes easier to align the position of the pad 1 with respect to the diaper 101, it becomes easier to place the pad 1 on the diaper 101 and wear it. Since the pad pattern 8 of this embodiment is a line-shaped figure provided approximately parallel to the front-rear direction, the maximum length d8 of the pad pattern 8 is approximately the same as the length d8 in the width direction at the front end of the pad pattern 8, but is not limited thereto. The maximum length d8 of the pad pattern 8 may be different from the widthwise length at the front end of the pad pattern 8. In the present embodiment, the pad pattern 8 and the diaper pattern 108 have the same configuration not only at the front end in the front-rear direction but also at the rear end, but only the front side or only the rear side of the pad 1 and the diaper 101 may have such a configuration. The fact that the colors are "different" can be determined by the above-mentioned method. In the present embodiment, the diaper 101 has a central portion 108b between the side ends 108a in the width direction of the diaper pattern 108 at the front end of the diaper 101, the central portion 108b having a color different from the color of the side ends 108a. However, the present invention is not limited to this.The diaper pattern 108 may be a continuous figure (pattern) in the width direction formed in the same color from one end to the other end in the width direction of the diaper pattern 108, without having a central portion with a different color from the side ends. Similarly, although the pad 1 of the present embodiment is formed of a continuous figure (pattern) from one end to the other end in the width direction, at the front end portion of the pad 1, a central portion different in color from the side end portions in the width direction may be provided between the side end portions of the diaper pad pattern 8.

[0105] Also, as described above, the diaper 101 has a pair of leak - proof wall portions 106 on both sides in the width direction, and each of the leak - proof wall portions 106 includes a side sheet 105 along the front - rear direction, and preferably includes an adhesion region (fixed portion) A101 that fixes the side sheet 105 to the surface sheet 102 (adjacent member) in the thickness direction. In such a case, in the deployed and extended states of the pad 1 and the diaper 100, the value of the distance L106s between the inner ends 106s in the width direction of the adhesion region A101 at the center CL2 in the front - rear direction of the diaper 101, and the value of the length H106 from the inner end 106s of the adhesion region A101 inside in the width direction to the inner end of the side sheet 105 (see FIGS. 5 and 7), it is preferable that the sum (L106s + H106) is smaller than the sum of the value of the length L1 in the width direction at the center in the front - rear direction of the pad 1 and the value obtained by doubling the maximum thickness T1 in the thickness direction of the absorption pad 1 (L1+T1×2) (L106s + H106 < L1+T1×2). Note that the standing point 106s of the leak - proof wall portion 106 in the width direction is also the inner end in the width direction of the adhesion region A101.

[0106] FIG. 11 is a diagram schematically showing a cross-section at the center CL1 in the front-rear direction of the pad 1 and the diaper 1 in the worn state. In the unfolded and extended states of the pad 1 and the diaper 101, when L106s + H106 < L1 + T1×2, when the pad 1 is placed on the skin side of the diaper 101 and the diaper 101 and the pad 1 are worn, as shown in FIG. 11, in the width direction, inside the leakage-preventing wall portion 106 of the diaper 101, and in the thickness direction, the pad 1 is located on the non-skin side rather than the inner end in the width direction of the side sheet 5 of the diaper 101 that is raised on the skin side by the leakage-preventing wall elastic member 107, and the pad 1 is more likely to fit inside the leakage-preventing wall portion 106 of the diaper 1. Thereby, in the worn state, the possibility that the position of the pad 1 with respect to the diaper 101 shifts can be reduced. Even if excrement leaks outside the width direction of the pad 1 in the worn state, the excrement can be blocked by the leakage-preventing wall portion 106 of the diaper 101, so that the possibility that the excrement leaks outside the absorbent article (the pad 1 and the diaper 101) can be reduced.

[0107] Also, the pad 1 preferably has a straight line portion SL along the front-rear direction at the side end in the width direction. When the diaper 1 has a leakage-preventing wall portion 106, the side end of the adhesion region A101 preferably has a straight line portion along the front-rear direction. And the distance L106s (FIGS. 8, 10, etc.) between the inner ends 106s in the width direction of the adhesion region A101 at the central portion (central CL2) in the front-rear direction of the unfolded and extended diaper 101, and the length L1 (FIGS. 1, 10, etc.) in the width direction at the central portion (central CL1) in the front-rear direction of the unfolded and extended pad 1 are preferably 0 mm or more and 20 mm or less (0 mm ≦ L106s - L1 ≦ 20 mm). Thereby, it becomes easier to store the pad 1 along the adhesion region A101 of the leakage-preventing wall portion 106 of the diaper 1 inside the leakage-preventing wall portion 106 of the diaper 1, and the possibility that the position of the pad 1 with respect to the diaper 1 shifts can be reduced. Therefore, the discomfort given to the wearer due to the inclination of the pad 1 with respect to the diaper 1 and the possibility of excrement leakage can be reduced.

[0108] Regarding the straight portion SL of the pad 1 and the straight portion of the adhesion region A101 of the diaper 1, the value (L106s - L1) obtained by subtracting the length L1 in the width direction at the center SL1 in the front-rear direction of the pad 1 in the unfolded and extended state from the distance (L106s) between the inner ends 106s in the width direction of the adhesion region A101 at the center SL2 in the front-rear direction of the diaper 101 in the unfolded and extended state is 0 mm or more and is preferably shorter than the length H106 from the inner end 106s of the adhesion region A101 on the inner side in the width direction of the diaper 101 to the inner end of the side sheet 105 (0 mm ≤ L106s - L1 < H106). Thereby, it becomes easier to accommodate the pad 1 inside the leak prevention wall portion 106 of the diaper 1 along the adhesion region A101 of the leak prevention wall portion 106 of the diaper 1, and the possibility of the position of the pad 1 shifting with respect to the diaper 1 can be reduced. Therefore, it is possible to reduce the discomfort given to the wearer due to the inclination of the pad 1 with respect to the diaper 1 and the possibility of leakage of excrement.

[0109] Generally, the longer the length L11 in the width direction of the absorber 10 of the pad 1, the higher the absorbency. However, considering the shape of the body, if the length L11 is too long, it will give the wearer a sense of discomfort. Therefore, the length L11 in the width direction of the absorber 10 of the pad 1 in the present embodiment is preferably 240 mm or less. And when the pad 1 is placed on the skin side surface of the diaper 101, in order to accommodate the absorber 10 of the pad 1 inside the leak prevention wall portion 106 of the diaper 101, the distance (L106s) between the inner ends 106s in the width direction of the adhesion region A101 at the center SL2 in the front-rear direction of the diaper 101 in the unfolded and extended state is preferably 240 mm or more. Thereby, it becomes easier to accommodate the pad 1 inside the leak prevention wall portion 106 of the diaper 1, and the possibility of the position of the pad 1 shifting with respect to the diaper 1 can be reduced. Therefore, it is possible to reduce the discomfort given to the wearer due to the inclination of the pad 1 with respect to the diaper 1 and the possibility of leakage of excrement.

[0110] In the present embodiment, when the pad 1 has a pair of leakage preventing walls (pad leakage preventing walls) 6 on both sides in the width direction, each of which has a leakage preventing wall elastic member (pad leakage preventing wall stretchable member) 7 stretching in the front-rear direction, and the diaper 101 has a pair of leakage preventing walls (diaper leakage preventing walls) 106 on both sides in the width direction, each of which has a leakage preventing wall elastic member (diaper leakage preventing wall stretchable member) 107 stretching in the front-rear direction, it is preferable that the leakage preventing wall elastic member 7 of the pad 1 and the leakage preventing wall elastic member 107 of the diaper 101 are colored. Note that the determination of "colored" can be made in the same manner as described above. By visually checking the leakproof wall elastic member 7 of the pad 1 and the leakproof wall elastic member 107 of the diaper 101 in addition to the pad pattern 8 and the diaper pattern 108, the wearer can easily recognize the front-to-back directions of the pad 1 and the diaper 101 relative to the wearer's body, and the front-to-back direction of the pad 1 relative to the front-to-back direction of the diaper 101, making it easier to don the pad 1.

[0111] Furthermore, it is more preferable that the color of the leakproof wall elastic member 7 of the pad 1 and the color of the leakproof wall elastic member 107 of the diaper 101 are the same color. For example, the leakproof wall elastic member 7 of the pad 1 can be blue, and the leakproof wall elastic member 107 of the diaper 101 can be blue. The determination of "same color" can be performed in the same manner as described above. When the color of the leakproof wall elastic member 7 and the color of the leakproof wall elastic member 107 are the same color, the wearer can easily recognize that the leakproof wall elastic member 7 and the leakproof wall elastic member 107 indicate the front-to-rear direction in addition to the pad pattern 8 and the diaper pattern 108, and by visually recognizing the leakproof wall elastic member 7 of the pad 1 and the leakproof wall elastic member 107 of the diaper 101, the wearer can easily recognize the front-to-rear direction of the pad 1 and the diaper 101 relative to the wearer's body, and the front-to-rear direction of the pad 1 relative to the front-to-rear direction of the diaper 101, which makes it easier to wear the pad 1.

[0112] The pad 1 and the diaper 101, when contained in the packages 50, 500, are folded toward the skin at the folds F1, F10, respectively. Therefore, the pad 1 has a pad front fold (pad one-side fold) F1a closest to the front-rear center position CL1 at the front side (one side) in the front-rear direction, and a pad rear fold (pad other-side fold) F1b closest to the front-rear center position CL1 at the rear side (other side) in the front-rear direction. The diaper 101 has a diaper front fold (diaper one-side fold) F10a closest to the front-rear center position CL2 at the front side (one side) in the front-rear direction, and a diaper rear fold (diaper other-side fold) F10b closest to the front-rear center position CL2 at the rear side (other side) in the front-rear direction.

[0113] When the pad 1 is placed on the diaper 101 so that the pad front fold F1a and the diaper front fold F10a overlap, it is preferable that the diaper 101 has an overlapping portion with the diaper 101 having the shortest widthwise length and the diaper 1s having the shortest widthwise length. FIG. 10 shows the pad 1 placed on the diaper 101 so that the pad front fold F1a and the diaper front fold F10a overlap. In the pad 1, the shortest widthwise length is provided in the crotch portion 1m of the pad 1 that is located under the crotch of the wearer when the pad 1 is worn. In the diaper 101, the shortest widthwise length is provided in the crotch portion Y of the diaper 101 that is located under the crotch of the wearer when the diaper 101 is worn. As shown in FIG. 10, the diaper 101 has an overlapping portion with the diaper 101s having the shortest widthwise length and the diaper 1s having the shortest widthwise length. When the pad 1 is overlapped with the diaper 101 so that the pad front fold F1a and the diaper front fold F10a overlap, the pad 1 and the diaper 101 are correctly combined when the diaper 101 has an overlapping portion with the shortest widthwise portion 101s and the shortest widthwise portion 1s of the pad 1. When the pad 1 and the diaper 101 have an overlapping portion with the shortest widthwise portion 1s of the pad 1, the pad 1 and the diaper 101 are correctly combined. When the diaper 101 has an overlapping portion with the shortest widthwise portion 101s and the shortest widthwise portion 1s of the pad 1 when viewed from the skin side, the pad 1 and the diaper 101 can be easily properly worn under the crotch of the wearer. This makes it difficult for the wearer to feel uncomfortable due to the pad 1 and the diaper 101, and by not feeling uncomfortable, the wearer can easily recognize that the pad 1 and the diaper 101 are worn in the correct wearing direction.

[0114] On the other hand, it is preferable that when the pad 1 is placed on the diaper 101 so that the front folded portion F1a of the pad overlaps with the rear folded portion F10b of the diaper as viewed from the skin side, the portion 101s of the diaper 101 having the shortest widthwise length and the portion 1n of the pad 1 having the longest widthwise length are overlapped. FIG. 12 is a diagram illustrating a state in which the pad 1 is placed on the diaper 101 so that the front folded portion F1a of the pad overlaps with the rear folded portion F10b of the diaper as viewed from the skin side. FIG. 12 is also a diagram illustrating a state in which the pad 1 is placed on the diaper 101 so that the center of the width of the pad 1 overlaps with the center of the width of the diaper 101 as viewed from the skin side. The state in which the pad 1 is placed on the diaper 101 so that the front folded portion F1a of the pad overlaps with the rear folded portion F10b of the diaper as viewed from the skin side means a state in which the front-rear direction of the pad 1 is reversed with respect to the diaper 101. In this state, as shown in Fig. 12, the portion 101s of the diaper 1 with the shortest widthwise length and the portion 1n of the pad 1 with the longest widthwise length overlap, which tends to cause discomfort to the wearer. When the diaper 101 and pad 1 in the state shown in Fig. 12 are worn, the portion 1n of the pad 1 with the longest widthwise length is provided in the crotch portion Y of the diaper 101, which tends to cause discomfort to the wearer due to the long widthwise length of the pad 1. In this way, when the front-to-back direction of the pad 1 and the diaper 1 are worn incorrectly, the wearer tends to feel uncomfortable, which makes it easier for the wearer to recognize the correct wearing orientation of the pad 1 and the diaper 101.

[0115] The above-mentioned pad 1 and diaper 101 can be manufactured in the following manner. A step of providing the pad 1 with a pad pattern 8 that is visible from the skin side; The pad 1 and the diaper 101 are manufactured by a manufacturing method including a step of providing the diaper 101 with a diaper pattern 108 that is visible from the skin side. The pad pattern 8 has a predetermined length in the front-to-back direction of the pad, and the diaper pattern 108 is provided to have a predetermined length in the front-to-back direction of the diaper 101, and the widthwise length d8 of the pad pattern 8 and the widthwise length d108 of the diaper pattern 108 are different. When the pad 1 and the diaper 101 manufactured by this manufacturing method are worn by placing the pad 1 on the skin side of the diaper 1, the maximum widthwise length d8 of the pad pattern 8 on the pad 1 is different from the widthwise length d108 of the diaper pattern 108 on the diaper 101, making it easier to visually distinguish the pad 1 from the diaper 101. In addition, the pad pattern 8 and the diaper pattern 108 are visible from the skin side and aligned in the front-to-back direction, respectively, making it easier for the wearer to recognize the front-to-back direction of the pad 1 and the front-to-back direction of the diaper 101 when worn, making it easier to align the position of the pad 1 with respect to the diaper 101. In addition, the pad pattern 8 and the diaper pattern 108 are aligned in the front-to-back direction, respectively, making it easier for the wearer to recognize the front-to-back direction of the pad 1 and the diaper 101 with respect to the wearer's body. Therefore, it becomes easier for the wearer to place the pad on the diaper 101 and wear it.

Furthermore, the present invention may be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.
