Detailed Implementation

[0025] (1) Overview of the implementation method

[0026] Method 1 is an absorbent article comprising: mutually orthogonal front-back, width, and thickness directions; an absorbent core having absorbent material; a skin-side sheet located closer to the skin than the absorbent core; and a placement area containing amino acids. The placement area is located on the skin side of the skin-side sheet covering the outer side of the absorbent core in the width direction. The skin-side sheet is located closer to the skin than the absorbent core. The placement area containing amino acids is located on the skin-side sheet, thus easily imparting the effects of amino acids before absorbing bodily fluids. Furthermore, the skin-side area of ​​the skin-side sheet covering the side of the absorbent core in the width direction easily rubs against the legs during walking, etc., and easily adheres to the skin. By placing amino acids in this area that easily adheres to the skin, the amino acids easily come into contact with the skin, and easily impart the effects of amino acids before absorbing bodily fluids.

[0027] According to a preferred embodiment, the technical solution of embodiment 2, in addition to the technical solution of embodiment 1, may have the following features: The skin-side sheet covers the side of the absorbent core in the width direction. The configuration area is located in the area of ​​the skin-side sheet covering the side of the absorbent core in the width direction. The area of ​​the skin-side sheet covering the side of the absorbent core in the width direction is more likely to come into contact with the leg. According to this embodiment, by configuring amino acids in the area that is more likely to come into contact with the leg, it is easier to impart the effects of amino acids to the user.

[0028] According to a preferred embodiment, the technical solution of embodiment 3, in embodiment 1 or embodiment 2, may have the following features: The skin-side panel has a folded-back portion that folds back towards the non-skin side. The absorbent article has a side panel that abuts against the non-skin side of the folded-back portion. The configuration area is provided on both the side panel and the skin-side panel. The amount of amino acids in the skin-side panel is greater than that in the side panel. The side panel easily comes into contact with the leg. According to this embodiment, by also configuring amino acids in the side panel, it is easier to impart the effects of amino acids. In addition, the skin-side panel with the folded-back portion easily bulges towards the skin side when worn, making it easier to abut against the skin compared to the side panel. By configuring amino acids over a large area in this skin-side panel that easily abuts against the skin, the effects of amino acids can be imparted to the user more efficiently.

[0029] According to a preferred embodiment, the technical solution of embodiment 4, in any of embodiments 1 to 3, may have the following features: A mixture of the amino acid and a solvent is disposed in the configuration area. The skin side panel has a folded-back portion that folds back towards the non-skin side. The absorbent article has a side panel that abuts against the non-skin side of the folded-back portion and a sheet-jointing portion that joins the folded-back portion to the side panel. The sheet-jointing portion has a first sheet-jointing portion disposed at least in the crotch area of ​​the wearer's crotch and a second sheet-jointing portion disposed at a position further outward in the width direction than the first sheet-jointing portion. The configuration area of ​​the skin side panel is disposed at a position further outward in the width direction than the first sheet-jointing portion. According to this embodiment, by mixing and configuring the solvent and amino acid, the texture of the configuration area becomes smooth, making it easier for the amino acid to exert its moisturizing and barrier functions on the skin. In addition, since the configuration area of ​​the skin side panel is disposed at a position further outward in the width direction than the first sheet-jointing portion, the reduction in the strength of the first sheet-jointing portion due to the solvent is suppressed, and the bonding strength of the first sheet-jointing portion is easily maintained.

[0030] According to a preferred embodiment, the technical solution of embodiment 5, in any of embodiments 1 to 4, may have the following features: The absorbent article comprises: an auxiliary sheet disposed between the top sheet and the absorbent core; and a sheet compression portion formed by compressing the top sheet and the auxiliary sheet in the thickness direction. The sheet compression portion is located in the disposed region of the skin-side sheet. According to this embodiment, amino acids are permeated in both the auxiliary sheet and the skin-side sheet, and the amino acids are easily retained by the high-density sheet compression portion.

[0031] According to a preferred embodiment, the technical solution of embodiment 6, in any of embodiments 1 to 5, may have the following features: The configuration region of the skin-side sheet is configured over the entire area of ​​the skin-side sheet in the front-back direction. The absorbent article has: a back sheet configured on the non-skin side of the absorbent core; and an edge compression portion configured along the outer edge of the absorbent article, formed by compression of the skin-side sheet and the back sheet in the thickness direction. The bending stiffness of the edge compression portion overlapping the configuration region is lower than the bending stiffness of the edge compression portion not overlapping the configuration region. According to this embodiment, the bending stiffness of the edge compression portion at the configuration region where amino acids are configured is lower, thus allowing the region for imparting amino acids to be finely processed to be soft, improving skin feel, and more effectively imparting the efficacy of amino acids. On the other hand, by increasing the bending stiffness of the edge compression portions not overlapping the configuration region, the shape of the absorbent article can be maintained, and the bonding state between the sheets can be maintained, thus maintaining the performance as an absorbent article.

[0032] According to a preferred embodiment, the technical solution of embodiment 7, in any of embodiments 1 to 6, may have the following features: A main compression portion having the top sheet and the absorbent core compressed in the thickness direction. The main compression portions are respectively disposed on both sides of the center in the width direction of the absorbent article. The configuration area is disposed on both sides in the width direction relative to the main compression portions. A blood modifier that improves the absorption of bodily fluids is disposed in the region between the main compression portions in the width direction of the skin side sheet. The region on the outer side in the width direction of the main compression portions is prone to bulging when the absorbent article deforms with the main compression portions as a base point, making it easier to contact the skin. According to this embodiment, by providing the configuration area in this region that is easy to contact the skin, it is easier to impart the effects of amino acids to the user. In addition, the region sandwiched between the two main compression portions is easy to be configured opposite to the excretion port, making it easier to guide bodily fluids. By providing the modifier at a position on the inner side in the width direction of the region sandwiched between the main compression portions, it is possible to improve the absorption of bodily fluids in areas where a large amount of bodily fluids are guided.

[0033] According to a preferred embodiment, the technical solution of embodiment 8, in any of embodiments 1 to 7, may have the following features: A recess is provided across the top sheet and the absorbent core. The recess has a wall extending in the thickness direction and a cut-off portion formed in the top sheet. The configuration region is disposed on both sides in the width direction relative to the recess. According to this embodiment, the configuration region can further impart the efficacy of amino acids to the user, and the introductory properties of the fluid are improved by utilizing the recess located inside the configuration region in the width direction and closer to the excretion opening than the configuration region.

[0034] According to a preferred embodiment, the technical solution of embodiment 9, in any of embodiments 1 to 8, may have the following features: It has a wing that extends outward in the width direction relative to the absorbent core and folds back towards the non-skin side of the garment during wear. The wing has a wing fixing portion fixed to the non-skin side of the garment and folds back towards the skin side of the skin-side sheet before use. In the folded-back state, the configuration area is positioned outward in the width direction from the outer edge of the wing fixing portion. When the wing is fixed to the garment, it is easy to fold back towards the non-skin side of the garment using the crease from the folding back before use as a reference point. Therefore, the position outward in the width direction from the outer edge of the wing fixing portion is an area that easily floats towards the skin side when the wing is wrapped around the garment. According to this embodiment, by providing a configuration area in this easily floatable area, amino acids are more easily brought into contact with the skin.

[0035] According to a preferred embodiment, the technical solution of embodiment 10, in any of embodiments 1 to 9, may have the following features: It has a hip wing that extends outward in the width direction relative to the absorbent core and is positioned on the skin side of the garment during wear. The hip wing has a hip fixing portion fixed to the skin side of the garment and folds back towards the skin side of the skin side sheet before use of the absorbent garment. In the folded-back state, the positioning area overlaps with the hip fixing portion. According to this embodiment, in the folded-back state, the positioning area overlaps with the hip fixing portion, thus amino acids are easily transferred to the skin side surface of the hip wing in the area overlapping with the hip fixing portion. During wear, the hip wing is positioned on the skin side of the garment, and the area overlapping with the hip fixing portion is fixed to the garment, making it easy to press against the skin with the garment. When pressed against the skin with the garment, the amino acids transferred in the area overlapping with the hip fixing portion can come into contact with the skin.

[0057] The top sheet 21 may have a top fold-back portion 22 that folds back towards the non-skin side T2. Specifically, the top sheet 21 folds back towards the non-skin side T2 with the first top crease F11 as the base point, extends towards the non-skin side using the outer edge of the absorbent core 30, and folds back inward in the width direction W with the second top crease F12 as the base point, extending inward along the non-skin side T2 of the absorbent core 30 towards the width direction. The top sheet 21 has a portion disposed on the skin side T1 (the non-fold-back portion other than the top fold-back portion 22) and a portion disposed on the non-skin side T2 (the top fold-back portion 22). The non-fold-back portion is the area extending between the left and right first top creases F11. The top fold-back portion 22 is the area extending towards the non-skin side T2 relative to the first top crease F11, covering the side of the absorbent core 30 in the width direction and the non-skin side of the absorbent core 30.

[0058] The auxiliary sheet 27 may have an auxiliary fold-back portion 28 that folds back towards the non-skin side T2. Specifically, the auxiliary sheet 27 folds back towards the non-skin side T2 with the first auxiliary fold 21 as a base point, extends towards the non-skin side T2 using the outer edge of the absorbent core 30, folds back inward in the width direction W with the second auxiliary fold 22 as a base point, and extends inward along the non-skin side T2 of the absorbent core 30 towards the width direction W. The auxiliary sheet 27 has a portion disposed on the skin side T1 (the non-fold-back portion other than the auxiliary fold-back portion 28) and a portion disposed on the non-skin side T2 (the auxiliary fold-back portion 28). The non-fold-back portion is the area extending between the left and right first auxiliary folds F21. The auxiliary fold-back portion 28 is the area extending towards the non-skin side T2 relative to the first auxiliary fold 21, covering the side of the absorbent core 30 in the width direction and the non-skin side of the absorbent core 30. The top fold-back portion 22 may be disposed at a position closer to the non-skin side T2 than the auxiliary fold-back portion 28.

[0059] The first top crease F11, the second top crease F12, the first auxiliary crease F21, and the second auxiliary crease F22 extend along the front-back direction L. The left and right top fold-back portions 22 can be separated in the width direction W, and the left and right auxiliary fold-back portions 28 can be separated in the width direction W. The first top crease F11, which is the outer edge of the top fold-back portion 22, and the first auxiliary crease F21, which is the outer edge of the auxiliary fold-back portion 28, can be located on the outer side in the width direction, which is further outward than the outer edge of the absorbent core 30 and the outer edge of the core sheet. Furthermore, in this embodiment, a portion of the fold-back portion (the area folded back using the second top crease F12 and the second auxiliary crease F22) is disposed on the non-skin side T2 of the absorbent core 30, but in a modified example, it can be disposed on the skin side T1 of the absorbent core 30. The top fold-back portion 22 and the auxiliary fold-back portion 28 can constitute the "fold-back portion of the skin side sheet" of this utility model.

[0060] The absorbent article 1 may have a side sheet 15 that abuts against the non-skin side T2 of the folded-back portion of the skin-friendly side sheet, and a sheet-jointing portion 50 that joins the folded-back portion to the side sheet 15. The side sheet 15 is positioned on the non-skin side T2 of the top folded-back portion 22 and closer to the skin side T1 than the back sheet 25. The side sheet 15 may extend to a position further outward in the width direction W than the top sheet 21. The side sheet 15 may be positioned as a wing. The side sheet 15 is joined to the top folded-back portion 22 via the sheet-jointing portion 50. The sheet-jointing portion 50 may be an area with adhesive.

[0061] Figure 5 This is a diagram showing the top fold-back portion 22 and the sheet joint portion 50. For ease of explanation, in... Figure 5 In this embodiment, structures other than the top sheet 21 and the sheet-jointing portion 50 are omitted. The sheet-jointing portion 50 may have a first sheet-jointing portion 51 disposed at least in the crotch region S3 and a second sheet-jointing portion 52 disposed on the outer side of the first sheet-jointing portion 51 in the width direction W. The first sheet-jointing portion 51 may be disposed at least in the crotch region S3, or it may be continuous over the entire area of ​​the skin-side sheet in the front-rear direction L, as in this embodiment. The second sheet-jointing portion 52 may be provided in a region extending rearward from the front edge of the absorbent article 1 and in a region extending forward from the rear edge of the absorbent article 1. The front second sheet-jointing portion 52 and the rear second sheet-jointing portion 52 may be separated in the front-rear direction L. The second sheet-jointing portion 52 may not be disposed in the crotch region S3, but may be disposed in the front region S1 and the rear region. The first sheet-jointing portion 51 and the second sheet-jointing portion 52 may be separated in the width direction W.

[0062] The outer edge 22E of the top fold-back portion 22 in the width direction W is located outside the outer edge 50E of the sheet joint portion 50 in the width direction W, i.e., the outer edge 52E of the second sheet joint portion 52 in the width direction W. The outer edge 50E of the sheet joint portion 50 is located inside the outer edge 22E of the top fold-back portion 22 in the width direction, so the outer part of the top fold-back portion 22 easily rises towards the skin side T1 with the sheet joint portion 50 as the base point. By the top fold-back portion 22 rising towards the skin side T1 with the sheet joint portion 50 as the base point, the skin feel on the wearer's leg can be softened. In addition, the inner edge 22I of the top fold-back portion 22 in the width direction W is located inside the inner edge 51I of the first sheet joint portion 51 in the width direction W, i.e., the inner edge 51I of the first sheet joint portion 51 in the width direction W.

[0063] The absorbent article 1 of this embodiment contains amino acids and has a configuration region RA in which amino acids are configured. Examples of amino acids include lysine hydrochloride, histidine, glutamic acid, aspartic acid, threonine, arginine, alanine, allantoin, proline, hydroxyproline, tyrosine, serine, taurine, glycine, phenylalanine, isoleucine, leucine, and valine. Among these, lysine hydrochloride, glutamic acid, aspartic acid, threonine, arginine, alanine, allantoin, proline, and hydroxyproline are preferred. By incorporating amino acids, moisturizing and skin barrier functions can be achieved. Examples of amino acids that can be used include Pellicer (registered trademark) from Asahi Kasei Corporation and L-glycine from HANGZHOU FOCUS CORPORATION.

[0064] Regarding the method of containing amino acids, a solution such as an oil containing amino acids can be applied to the material constituting the absorbent article 1, or the solution can be sprayed onto the material. In this embodiment, a mixture of amino acids and a solvent is applied to the non-skin side T2 of the top sheet 21. That is, the configuration area RA can be configured with amino acids and a solvent. According to this method, by mixing the solvent and amino acids, the texture of the configuration area RA becomes smooth, making it easier to exert the moisturizing and barrier functions of amino acids for the skin. Regarding the mixture, it can be that the amino acids are dissolved in the solvent, or it can be mixed with the solvent in a state that allows them to be separated from the amino acids. There are no particular limitations on the solvent, but it can also be a water-soluble organic compound. The solvent can also be an oil. Polyols are preferably used as the solvent. The solvent in this embodiment is Wako1st Grade from Fujifilm and Kojun Pharmaceutical Co., Ltd. The mixing ratio (by weight) of amino acids to solvent can be about 1:1 to 1:30. Whether amino acids are present can be evaluated, for example, by referring to FZ / T 50049-202 described later.

[0065] Amino acids can be infiltrated into the top sheet 21 and disposed on the skin-side T1 surface and side surfaces of the absorbent article 1. The disposal area RA can be provided at least on the skin-side T1 surface of the absorbent article 1. In this embodiment, the disposal area RA extends along the front-back direction L on the outer sides of both sides of the skin-side T1 surface of the top sheet 21, and is provided in three intervals in the width direction W, with one area disposed on each side surface of the top sheet 21.

[0066] The configuration area RA can be located in the skin side T1 region of the skin side sheet covering the outer portion of the absorbent core 30 in the width direction W. In this embodiment, the configuration area RA is located in the skin side T1 region of the top sheet 21, which serves as the skin side sheet, covering the outer portion of the absorbent core 30 in the width direction W. Furthermore, the outer portion of the absorbent core 30 is the lateral region in the region divided into three equal parts in the width direction W of the absorbent core 30. The configuration area RA can be configured to at least partially overlap with the outer portion of the absorbent core 30.

[0067] The skin-side sheet is located at the T1 position, closer to the skin than the absorption core 30, and is positioned very close to the skin. The placement area RA is located on the skin-side sheet, thus facilitating the delivery of amino acids even before the absorption of bodily fluids. Furthermore, the skin-side area of ​​the skin-side sheet covering the width of the absorption core 30 is prone to friction with the legs during walking, ensuring close contact with the skin. By placing amino acids in this area that facilitates close contact with the skin, the amino acids easily come into contact with the skin, facilitating the delivery of amino acid effects even before the absorption of bodily fluids.

[0068] The configuration area RA can be located on the side of the absorbent core 30 covering the skin side sheet. In this embodiment, the configuration area RA is located on the side of the absorbent core 30 covering the skin side sheet in the width direction W. The side of the absorbent core 30 covering the skin side sheet in the width direction is more likely to come into contact with the leg. According to this method, by configuring amino acids in an area that is easy to come into contact with the leg, it is easier to impart the effects of amino acids to the user.

[0069] The application area RA can be located on both the side panel 15 and the skin-friendly side panel. The application area RA on the side panel 15 can be either an area where amino acids are directly applied to the side panel 15, or an area where amino acids are transferred to the skin-friendly side panel. The amount of amino acids on the skin-friendly side panel can be greater than that on the side panel 15. The side panel 15 is designed to easily contact the leg. By also applying amino acids to the side panel 15, it is easier to apply the benefits of amino acids. Furthermore, the skin-friendly side panel with a folded portion tends to bulge towards the skin when worn, making it easier to contact the skin compared to the side panel 15. By applying more amino acids to this skin-friendly side panel, which is easier to contact the skin, the benefits of amino acids can be applied to the user more efficiently. On the other hand, the side panel has less amino acids, thus suppressing the influence of amino acids on the wing fixing portion 62.

[0070] The amount of amino acids in the skin-facing sheet and the amount of amino acids in the side sheet 15 can be compared by FZ / T 50049-2020 (a standard test method for the textile industry of the People's Republic of China) after the side sheet and the skin-facing sheet are taken out from the absorbent article. FZ / T 50049-2020 implements a color development reaction after amino acids are eluted with strong potassium solution (Japanese: 強カリウム液), then quantifies and compares the amino acids using an amino acid analyzer. Alternatively, a solvent capable of eluting amino acids is applied to the side sheet and the topsheet respectively, and after extraction, centrifugal concentration is performed to prepare a sample. The pre-column derivatization method can also be used for the extracted amino acids, and the peak intensity is used to compare the amounts.

[0071] The bonding strength between the side sheet 15 of the first sheet bonding portion 51 and the folded portion of the skin-facing sheet can be higher than the bonding strength between the side sheet 15 and the back sheet 25. For example, in a configuration where amino acids and a solvent (such as polyol) are disposed, the bonding strength between materials may be reduced by the solvent. However, by increasing the bonding strength of the first sheet bonding portion 51, the bonded state of the materials can be maintained while the disposition area RA is provided.

[0072] Regarding the comparison of bonding strength, the following method can be exemplified.

[0073] (1) Leave the absorbent article to stand in a constant temperature and humidity chamber (temperature 23±2°C, relative humidity 50±5% RH) for 24 hours.

[0074] (2) Form a sample from the absorbent article that includes a bonded portion of two sheets and a non-bonded portion of two sheets. In addition, the non-bonded portion is used as a clamping portion for clamping to a jig of a tensile testing machine.

[0075] (3) Mount the non-bonded portions to one jig and the other jig of the tensile testing machine, such that the distance between chucks is 25 mm, the width is 25 mm, and the bonding portion is disposed between the one jig and the other jig. A T-peel test is performed on the sample at a speed of 100 mm / min under the condition of 25°C (if the width does not meet the requirement, the comparison can be performed with the maximum width).

[0076] (4) Read the maximum strength, which is the highest strength during the peeling of each sheet.

[0077] (5) Measure the above maximum strength for 10 times in total with different samples, and take the average value as the above bonding strength.

[0078] In addition, as the above tensile testing machine, the 5900 series universal material testing machine from Instron Japan can be mentioned.

[0079] The configuration area RA is located on the top sheet 21, and the non-skin side of the configuration area RA on the top sheet 21 can be covered by the auxiliary sheet 27. In the configuration where the absorbent core 30 or the core pack 38 abuts against the configuration area RA of the top sheet 21, amino acids are easily introduced to the absorbent core 30 side, and sometimes it is difficult to maintain amino acids continuously on the top sheet 21. However, by using the auxiliary sheet 27 to cover the non-skin side of the configuration area RA of the top sheet 21, the introduction of amino acids to the non-skin side T2 is inhibited, and amino acids are easily and continuously delivered to the skin via the top sheet 21.

[0080] like Figure 3 As shown, the skin-side patch arrangement area RA can be positioned lateral to the first joint portion 51 in the width direction W. At least a portion of the arrangement area RA can be positioned lateral to the outer edge 51E of the first joint portion 51 in the width direction, and the arrangement area RA can also overlap with the first joint portion 51. According to this method, since the arrangement area RA is positioned lateral to the first joint portion 51 in the width direction W, it is easier to suppress the decrease in strength of the first joint portion due to solvents such as polyols, and it is easier to maintain the bonding strength of the first joint portion 51. Furthermore, the skin-side patch arrangement area RA can overlap with the second joint portion 52.

[0081] The sheet compression portion 24 can be provided in the arrangement area RA of the skin-side sheet. According to this method, amino acids are permeably disposed on both the auxiliary sheet 27 and the skin-side sheet, and the amino acids are easily retained by the high-density sheet compression portion 24. In this embodiment, the sheet compression portion 24 is dot-shaped, and a plurality of them are arranged at intervals in the width direction W and the front-back direction on the outer side of the top sheet 21.

[0082] The edge compression portion 90 can be provided in areas overlapping with the placement area RA and areas not overlapping with the placement area RA. The bending stiffness of the edge compression portion 91 overlapping with the placement area RA can be lower than the bending stiffness of the edge compression portion 92 not overlapping with the placement area RA. According to this method, the bending stiffness of the edge compression portion 91 of the placement area RA is lower, so the area for imparting amino acids can be refined to be soft, improving the skin feel and more effectively imparting the efficacy of amino acids. On the other hand, by increasing the bending stiffness of the edge compression portion 92 not overlapping with the placement area RA, the shape of the absorbent article can be maintained, the bonding state between the sheets can be maintained, and the performance as an absorbent article can be maintained.

[0083] Here, bending stiffness can be determined using the KES method. Specifically, a KES-FB2-AUTO-A bending tester manufactured by Kado Technology Co., Ltd. can be used, and samples of separately measurable dimensions are prepared. Specifically, regions containing edge compression portions 90 overlapping with the configuration region RA and regions containing edge compression portions 90 not overlapping with the configuration region RA are prepared with the same dimensions. Then, each sample is fixed between the chucks of the tester in such a way that the lateral bending stiffness in each sample can be measured. The sample is bent towards the surface side to the maximum curvature +2.5 cm. -1 Next, bend it towards the back side to the maximum curvature of -2.5cm. -1 Then it is restored. The bending stiffness value is calculated based on the average of the slope when bending begins towards the surface side and the slope of the bending moment relative to the curvature becomes approximately constant, and the slope when bending begins towards the back side and the slope of the bending moment relative to the curvature becomes approximately constant. This is repeated 5 times for each sample, and the average value is taken as the bending stiffness.

[0084] The configuration area RA can be positioned outward in the width direction W from the main compression portions positioned on both sides of the center 1CW of the article width. In this embodiment, a central compression portion 83 is positioned on both sides of the center 1CW of the article width, and the configuration area RA is positioned outward in the width direction from the central compression portion 83. Furthermore, at least a portion of the configuration area RA may be positioned outward in the width direction from the central compression portion 83, and the configuration area RA may also overlap with the central compression portion.

[0085] A blood modifier that enhances the absorption of bodily fluids can be disposed in the area between the central compression portions 83 in the width direction of the skin-side sheet. Furthermore, at least a portion of the blood modifier may be disposed inside the central compression portions 83 in the width direction W, and the blood modifier may also overlap with the central compression portions 83. The blood modifier can be applied to the skin-side surface of the top sheet 21. The blood modifier is one that facilitates the absorption of menstrual blood; for example, a polypropylene glycol-based compound can be used. Figure 3 The modified region RB, in which a blood modifier is disposed, is shown. There are no particular limitations on the blood modifier, but the following blood modifiers can be cited as examples: NA50 from Nippon Oil Co., Ltd., Cetiol SB45DEO from Corning Japan Co., Ltd., and isopropyl citrate from Tokyo Chemical Industries, Ltd.

[0086] The region on the outer side of the central compression section 83 in the width direction W is more likely to bulge when the absorbent article deforms with the central compression section 83 as a base point, making it easier to come into contact with the skin. According to this method, by providing the configuration area RA in this area that easily comes into contact with the skin, it is easier to impart the effects of amino acids to the user. Furthermore, the region sandwiched between the central compression sections 83 on both sides is easily configured opposite to the excretion port, facilitating the drainage of bodily fluids. By providing a blood conditioner in this region sandwiched between the central compression sections, the absorption capacity of bodily fluids in areas where a large amount of bodily fluid is drained can be improved.

[0087] The configuration region RA can be disposed on both sides of the recess 85 in the width direction W. According to this method, the configuration region RA can further impart the effects of amino acids to the user, and the recess, located inside the configuration region RA in the width direction and closer to the excretion opening than the configuration region RA, improves the absorption of bodily fluids. Furthermore, at least a portion of the configuration region RA can be disposed outside the recess 85 in the width direction W, and the configuration region RA can also overlap with the recess 85. In configurations with multiple recesses, the configuration region RA can be located outside the outermost recess 85 in the width direction W.

[0088] The placement area RA can be positioned outward in the width direction W from the main body fixing part 61. This area, outward in the width direction W from the main body fixing part 61, is not fixed to the garment but easily floats off the garment. According to this method, by providing the placement area RA in this easily floatable area, amino acids can more easily come into contact with the skin. At least a portion of the placement area RA need to be positioned outward in the width direction W from the main body fixing part 61, and the placement area RA can have a portion overlapping the main body fixing part 61.

[0089] At least a portion of the configuration area RA can overlap with the narrowing portion 31. The area where the narrowing portion 31 is located is not equipped with the absorbent core 30, resulting in a soft feel against the skin. By configuring the configuration area RA in an overlapping manner with the narrowing portion 31, amino acids can be applied to the portion that softly contacts the skin, further enhancing the skin feel through both the softness of the skin and the efficacy of the amino acids.

[0090] like Figure 4As shown, the wing portions (wings and hip wings) can be folded back towards the skin side of the skin-side sheet before using the absorbent article 1. When the wings are folded back before use, the placement area RA can be positioned outside the outer edge 62E of the wing fixing portion 62 in the width direction W. When the wing 5 is fixed to the garment, it is easy to fold back towards the non-skin side of the garment based on the crease FW when folded back before use. Therefore, the position outside the outer edge of the wing fixing portion 62 in the width direction W is an area that is easy to float towards the skin side when the wing 5 is wrapped around the garment. According to this method, by providing the placement area RA in this area that is easy to float, amino acids are more likely to come into contact with the skin. In addition, it is sufficient for at least a portion of the placement area RA to be positioned outside the outer edge 62E of the wing fixing portion 62 in the width direction, but in this embodiment, the placement area RA is only positioned outside the outer edge 62E of the wing fixing portion 62 in the width direction W. The outer edge 62E of the wing fixing part 62 and the inner edge of the configuration area RA can also be adjacent.

[0091] When the hip support 7 is folded back before use, the configuration area RA can overlap with the hip fixation part 63. According to this method, with the hip support 7 folded back, the configuration area RA overlaps with the hip fixation part 63, thus easily transferring amino acids to the skin-side surface of the hip support 7 in the area overlapping with the hip fixation part 63. During wear, the hip support 7 is positioned on the skin-side T1 of the garment, and the area overlapping with the hip fixation part 63 is fixed to the garment, making it easy to press against the skin with the garment. When pressed against the skin with the garment, the amino acids transferred in the area overlapping with the hip fixation part 63 can come into contact with the skin. Furthermore, at least a portion of the configuration area RA needs to overlap with the hip fixation part 63; in this embodiment, the configuration area RA is positioned in the area overlapping with the hip fixation part 63 and in the area lateral to the outer edge 63E of the hip fixation part 63 in the width direction W.

[0092] The absorbent article 1 may have a display section 200 that evokes the image of amino acids. According to this embodiment, the absorbent article 1 is provided with a display section 200 that evokes the image of amino acids, so that the user can visually confirm the presence of amino acids by checking the display section 200. Thus, the user can identify the presence of amino acids before use, understand their effects, or become aware of the presence of amino acids during use, making it easier to actually experience the effects of amino acids. The display section 200 only needs to be a structure that allows the user to understand the presence of amino acids, and can include text indicating amino acids, designs that visualize amino acids, and text or images indicating the effects of amino acids. The display section 200 can be constructed by printing or by embossing or other raised or recessed parts. In this embodiment, the display section 200 is composed of a front compression section 81 and a rear compression section 82. The display section 200 can be provided in the front region S1 and the rear region S2 respectively, and can be visually recognized from the skin-side surface of the absorbent article 1. The display section 200 has text indicating amino acids disposed between the two ring-shaped portions and a design based on chemical structural formulas on the inner side of the ring-shaped portions. In addition, the display section can be provided on a peelable sheet that covers the fixing section in a peelable manner, on a packaging sheet that individually packages absorbent items, or on a storage body that stores multiple absorbent items.
