Detailed Implementation

[0025] (1) Overview of the implementation method

[0026] Method 1 provides a packaging for an absorbent article, comprising an absorbent article and a covering sheet. The absorbent article has mutually orthogonal front-to-back, width, and thickness directions, and contains amino acids. The covering sheet covers the non-skin side of the absorbent article. At least one of the absorbent article and the covering sheet has a display section associated with amino acids. According to this method, since at least one of the absorbent article and the covering sheet has a display section associated with amino acids, the user can visually identify the presence of amino acids through the display section. Therefore, the user can identify the presence of amino acids and understand their effects before use, or be aware of the presence of amino acids during use, and easily experience the effects of amino acids.

[0027] According to a preferred embodiment, the technical solution of embodiment 2, in embodiment 1, has the following features: The display unit can be visually identified from the outside of the packaging. The area where the amino acid is disposed is located on the skin-side surface of the absorbent article. The user can visually identify the outside surface of the packaging when opening and handling it, and can easily come into contact with the skin-side surface of the absorbent article during wearing. Since the display unit and amino acid are attached to the part that the user observes or touches during wearing, the user can notice the presence of the amino acid and obtain its efficacy, and can easily experience the effect of the amino acid.

[0028] According to a preferred embodiment, the technical solution of embodiment 3, in the technical solutions of embodiment 1 or embodiment 2, has the following characteristics: The display portion has an article display portion disposed on the absorbent article. The bending stiffness of the region where the amino acid is disposed is lower than the bending stiffness of the region where the article display portion is disposed. According to this embodiment, the region where the article display portion is disposed has higher bending stiffness, is less prone to wrinkling, and can maintain the visual legibility of the article display portion. On the other hand, the region where the amino acid is disposed has lower bending stiffness, resulting in a soft skin-like feel, and can more effectively impart the efficacy of the amino acid.

[0029] According to a preferred embodiment, for the technical solution of embodiment 4, any one of the technical solutions of embodiments 1 to 3 has the following characteristics: The display portion has an article display portion disposed on the absorbent article. The bonding strength between the materials overlapping the configuration area where the amino acids are disposed is lower than the bonding strength between the materials in the region where the article display portion is disposed. According to this embodiment, in the region where the article display portion is disposed, the bonding strength between the materials is higher, wrinkles are less likely to occur, and the visual legibility of the article display portion can be maintained. On the other hand, in the configuration area, the bonding strength between the materials is lower, resulting in a soft skin-like feel, which can more effectively impart the efficacy of the amino acids.

[0030] According to a preferred embodiment, for the technical solution of embodiment 5, any one of the technical solutions of embodiments 1 to 4 has the following characteristics: The display portion has an article display portion provided on the absorbent article. The maximum width of the article display portion is longer than the maximum width of the arrangement area where the amino acid is disposed. According to this embodiment, since the maximum width of the article display portion is longer, the article display portion can be made more conspicuous. The user can easily identify the presence of the amino acid through the article display portion. Since the maximum width of the arrangement area is shorter, the effect of the amino acid can be locally applied to the area where the amino acid is to be applied. For example, by arranging the amino acid in a manner that overlaps with the outer part of the absorbent core, the effect can be applied to the root of the leg and the groin area, and the skin can be protected against friction based on the legs, etc.

[0031] According to a preferred embodiment, for the technical solution of embodiment 6, any one of the technical solutions of embodiments 1 to 5 has the following features: The display portion has an article display portion disposed on the absorbent article. The article display portion is disposed at the center of the absorbent article in the width direction. The placement areas where the amino acids are disposed are respectively disposed on both sides of the article display portion in the width direction. The user can easily visually identify the article display portion disposed at the center of the absorbent article in the width direction, and can more easily grasp the presence of amino acids. The outer part of the absorbent article is more likely to come into contact with the legs. By placing amino acids in the area that is more likely to come into contact with the legs, the barrier effect on the skin based on the efficacy of amino acids is more easily exerted.

[0032] According to a preferred embodiment, for the technical solution of embodiment 7, in any of embodiments 1 to 6, the following features are present: The display section has an article display section provided on the absorbent article. The absorbent article is folded with the article crease extending in the width direction as a base point before use. The article display section is located in a position further forward than the article crease located at the foremost side. For the area further forward than the article crease located at the foremost side, it is easier for the user to see it when holding it or visually recognizing it while wearing it. Therefore, it is easier for the user to grasp the presence of amino acids. In addition, generally speaking, when folding the absorbent article with the article crease as a base point, folding is done from the side of the article crease located at the last side, and the article crease located at the foremost side is folded last. Therefore, when unfolding the absorbent article, the area further forward than the article crease located at the foremost side is unfolded first. The area further forward than the article crease located at the foremost side is unfolded first, making it easier to enter the user's field of vision. By placing an item display in this easily visible area, users can more easily grasp the presence of amino acids.

[0033] According to a preferred embodiment, for the technical solution of embodiment 8, any one of embodiments 1 to 7 has the following features: The absorbent article has a main wing that extends outward in the width direction relative to the absorbent core and is folded back towards the non-skin side of the article when worn. The main wing has a main wing fixing portion that is fixed to the non-skin side of the article and is folded back towards the skin side of the absorbent article before use. In the folded state of the main wing with the main wing folded back, the configuration area for amino acids is located on the outer side in the width direction beyond the outer edge of the main wing fixing portion. When the main wing is fixed to the article, it is easy to fold back towards the non-skin side of the article based on the crease when folded back before use. Therefore, the portion on the outer side in the width direction beyond the outer edge of the main wing fixing portion is an area that is easy to float towards the skin side when the main wing is rolled up around the article. By providing the configuration area in this easily floated area, the amino acids are more easily brought into contact with the skin.

[0034] According to a preferred embodiment, for the technical solution of embodiment 9, in any of embodiments 1 to 8, the technical solution has the following characteristics: The absorbent article has a hip flap that extends outward in the width direction relative to the absorbent core and is positioned on the skin side of the article when worn. The hip flap has a flap fixing portion that is fixed to the skin side of the article and is folded back towards the skin side before use of the absorbent article. In the folded-back state, the configuration area overlaps with the flap fixing portion. According to this embodiment, in the folded-back state, the configuration area and the flap fixing portion overlap, thus facilitating the transfer of amino acids to the skin side surface of the hip flap in the area overlapping with the flap fixing portion. When worn, the hip flap is positioned on the skin side of the article, and the area overlapping with the flap fixing portion is fixed to the article, making it easy to be pushed against the skin by the article. When the clothing is pressed against the skin, the amino acids transferred in the area overlapping with the wing attachment can come into contact with the skin.

[0035] According to a preferred embodiment, for the technical solution of embodiment 10, any one of the technical solutions of embodiments 1 to 9 has the following features: The covering sheet has a release sheet and a packaging sheet. The release sheet covers the attachment portion of the absorbent article to the worn article, and the packaging sheet is disposed on the non-skin side of the release sheet to individually package the absorbent article. Multiple display sections are provided in the absorbent article, the release sheet, and the packaging sheet. According to this embodiment, since multiple display sections are provided in the absorbent article, the release sheet, and the packaging sheet, the user can more easily visually identify the display sections and more easily grasp the presence of amino acids.

[0036] (2) Overall general structure of the packaging of absorbent articles

[0037] Hereinafter, the packaging body (hereinafter referred to as packaging body 100) of the absorbent article according to the first embodiment will be described with reference to the accompanying drawings. The packaging body 100 includes an absorbent article 1 and a cover sheet 40. The absorbent article 1 may be an absorbent article such as a sanitary napkin, panty liner, breast pad, adult incontinence pad, fecal pad, or sweat pad. The absorbent article 1 may be an article used to be installed inside a wearable item such as underwear.

[0038] Furthermore, in the following accompanying drawings, the same or similar reference numerals are used to label the same or similar parts. However, it should be noted that the drawings are schematic, and there may be differences between the actual dimensions and scales. Therefore, the specific dimensions should be determined by referring to the following explanation. Additionally, there may be instances where the dimensions or scales of the drawings differ from each other.

[0039] Figure 1 This is a top view of the package 100 in its unfolded state. Figure 2 This is a top view of the package 100 with the main wings folded. Figure 3 yes Figure 2 The rear view of the package 100 shown. Figure 1 and Figure 2 This is the state obtained by observing the packaging from the skin side (100%). Figure 3 This is the state obtained by observing the package 100 from the non-skin side. Additionally, the unfolded state is the state in which the absorbent article 1 and the covering sheet 40 are not folded by any crease. Figure 2 and Figure 3 The folded state of the main wing shown is that the absorbent item 1 and the covering sheet 40 are folded only at the main wing crease FW as the base point and not folded by other creases.

[0040] Additionally, the attached diagram shows the elongated state. Here, "elongated state" refers to the state in which the absorbent article is elongated to the point that the wrinkles of the absorbent article are no longer visually discernible. In contrast, "natural state" refers to the state after the absorbent article 1 has been placed for a predetermined time following rinsing the adhesive of the fixation part with a solvent such as toluene. For example, the absorbent article removed from the outer casing is temporarily placed in the "elongated state," and after maintaining this elongated state for 15 seconds, the stretching of the absorbent article is released and it is placed on a flat surface such as a table. Then, the state after lying flat on such a surface for 5 minutes is defined as the natural state. Regarding the positional relationships in this utility model (positional relationships in the front-to-back direction, positional relationships in the width direction, and positional relationships of overlapping arrangements), unless specifically mentioned, the positional relationship of the elongated state is defined.

[0041] The absorbent article 1 has mutually orthogonal front-to-back direction L, width direction W, and thickness direction. In the front-to-back direction L, the side that abuts against the wearer's lower abdomen is designated as the "front side," and the side that abuts against the wearer's buttocks is designated as the "back side." The width direction W is orthogonal to the front-to-back direction L and corresponds to the wearer's left-to-right direction. The thickness direction extends from the skin side of the wearer to the non-skin side. The "skin side" corresponds to the side facing the wearer's skin during use. The "non-skin side" corresponds to the side facing away from the wearer's skin during use.

[0042] Furthermore, in this invention, the outer portion refers to the part occupying a certain range in the width direction W, including the outer edge, and the outer edge refers to the outer edge in the width direction W. Additionally, the outer edge of a constituent member occupying a certain range in the front-rear direction L is an edge obtained by connecting all points of the constituent member located on the outer side in the width direction W throughout the constituent member. In this invention, the inner portion refers to the part occupying a certain range in the width direction W, including the inner edge, and the inner edge refers to the inner edge in the width direction W. Additionally, the inner edge of a constituent member occupying a certain range in the front-rear direction L is an edge obtained by connecting all points of the constituent member located on the inner side in the width direction W throughout the constituent member. Furthermore, in this invention, the front end and rear end are portions occupying a certain range in the front-rear direction L, including the edges, and the front edge and rear edge are edges in the front-rear direction L. The outer end includes the front end and the rear end, and the outer edge includes the front edge and the rear edge. Furthermore, the inner side is an edge that includes the inner edge and extends along the front-rear direction L. The outer edge is an edge that includes the outer edge and extends along the front-back direction L. Furthermore, in this specification, the term "along the front-back direction L" refers to a direction with an angle of less than 45° relative to the front-back direction L, and the term "along the width direction W" refers to a direction with an angle of less than 45° relative to the width direction W.

[0043] The absorbent article 1 has a crotch area S3, a front area S1, and a rear area S2. The crotch area S3 is located in the crotch of the wearer, opposite the wearer's excretory opening, such as a urinary opening. When the absorbent article 1 is installed in underwear, it is located in the crotch area of ​​the underwear and between the wearer's legs. The front area S1 is located further forward than the crotch area S3. The rear area S2 is located further back than the crotch area S3. The crotch area S3 can be either the area with the narrowing portion 31 described later, or the area between the first crease F1 and the second crease F2 described later. In this embodiment, the crotch area S3 is the area with the main wing 5.

[0044] The absorbent article 1 may have at least an absorbent core 30, a top sheet 21, and a bottom sheet 25. The absorbent core 30 has an absorbent material. Examples of absorbent materials include hydrophilic fibers, cellulose fibers (e.g., pulp), and superabsorbent polymers (SAP). The absorbent core 30 may be an absorbent sheet (so-called SAP sheet) with the skin side and non-skin side of the superabsorbent polymer covered by a sheet, or it may be a laminate containing at least a layer of pulp.

[0045] The absorbent core 30 may have a narrowed portion 31 that narrows inward in the width direction from its outer edge. The narrowed portion 31 may be disposed at least in the crotch region S3. In this embodiment, the narrowed portion 31 spans a portion of the crotch region S3, a portion of the front region S1, and a portion of the rear region S2. The skin-side and non-skin-side surfaces of the absorbent core 30 may be covered by a core-covering sheet such as thin cotton paper. The absorbent core 30 of this embodiment is a laminate containing pulp and a highly absorbent polymer. The absorbent core 30 is disposed at least in the crotch region S3. The absorbent core 30 may span at least one of the front region S1 and the rear region S2.

[0046] The top sheet 21 is positioned closer to the skin than the absorbent core 30, and comes into contact with the wearer's skin. The top sheet 21 may be liquid-permeable and made of non-woven fabric. The top sheet 21 may cover a portion of the absorbent core 30 (e.g., the center in the width direction) or the entire width W of the absorbent core 30. A compression section 80 may be provided in the absorbent article 1 to compress the top sheet 21 and the absorbent core 30 along the thickness direction.

[0047] The backing sheet 25 is positioned closer to the non-skin side than the absorbent core 30, forming the non-skin side of the absorbent article 1. The backing sheet 25 may be liquid-impermeable and made of a film. An attachment portion 60 may be provided on the non-skin side of the backing sheet 25. The attachment portion 60 is attached to the garment. An adhesive or mechanical hook may be provided on the attachment portion 60. The attachment portion 60 may have a main attachment portion 61 and a main wing attachment portion 62, the main attachment portion 61 being located in the area overlapping with the absorbent core 30, and the main wing attachment portion 62 being located on the main wing 5. The main attachment portion 61 is attached to the skin side of the garment, and the main wing attachment portion 62 is attached to the non-skin side of the garment. In this embodiment, the attachment portion 60 extends in the front-rear direction L and is spaced apart in the width direction W. In a modified example, the attachment portion may extend in the width direction W and be spaced apart in the front-rear direction L. The main body attachment 61 can be covered by the peeling sheet 41, which serves as a covering sheet 40, before the absorbent article 1 is used. The main wing attachment 62 can be covered by the main wing peeling sheet 43 before the absorbent article 1 is used.

[0048] The absorbent article 1 may have a wing portion extending outward in the width direction W relative to the absorbent core 30. Specifically, the wing portion may have at least one of a main wing 5 disposed at least in the crotch region S3 and a hip wing disposed at least in the rear region S2. The main wing 5 is folded back towards the non-skin side of the article when worn. The hip wing is not folded back towards the non-skin side of the article when worn, but is disposed on the skin side of the article. In this embodiment, the wing portion does not have a hip wing, but has a main wing 5. Figure 2 As shown, the main wing 5 is folded towards the skin side of the absorbent material 1 before use.

[0049] The cover sheet 40 may have at least one of a peel-off sheet 41 and a packaging sheet 42. The peel-off sheet 41 covers the non-skin side of the absorbent article 1 before use and separates from the absorbent article 1 during use. The packaging sheet 42 individually packages the absorbent article 1. The cover sheet 40 of this embodiment has both a peel-off sheet 41 and a packaging sheet 42. In the embodiment with both a peel-off sheet 41 and a packaging sheet 42, the peel-off sheet 41 is disposed between the absorbent article 1 and the packaging sheet 42. In the embodiment without a peel-off sheet 41 but with a packaging sheet 42, the packaging sheet 42 may be able to detachably cover the main body fixing portion 61. Furthermore, in a modified embodiment, the packaging sheet 42 may be omitted and only the peel-off sheet 41 may be provided.

[0050] The packaging body 100 is folded before use, and the absorbent article 1 is individually packaged using the packaging sheet 42. Figure 4 This is a top view of the individually packaged state of the absorbent article 1, which is separately packaged using packaging sheet 42. For the package 100, it can be seen from... Figure 1 The unfolded state shown is based on the wing crease FW, with the main wing 5 folded inward in the width direction W. The wing crease FW is a crease extending in the front-to-back direction L, and it is a crease that folds only the absorbent material 1 and not the covering sheet 40. Figure 2 and Figure 3The diagram shows the folded state of the main wing, folded with the main wing crease FW as the base point. For the packaging body 100, in the folded state of the main wing, folding is performed with the first crease F1 and the second crease F2, which serve as article creases, as base points. The article crease may be a crease extending along the width direction W, and it may be a crease that folds the absorbent article 1 and the covering sheet 40 together. The folding order of the first crease F1 and the second crease F2 is not limited. In this embodiment, after folding with the second crease F2 located on the rear side as the base point, folding is performed with the first crease F1 located on the front side as the base point to achieve the packaged state. Furthermore, in a configuration where a main wing and a hip flap are used as wing portions, the main wing crease may fold the hip flap and the main wing 5 together. Additionally, in a configuration without wing portions, the main wing crease may not be present, and folding is performed from the unfolded state with the article crease as the base point.

[0051] The packaging 100 of this embodiment contains amino acids. Examples of amino acids include lysine hydrochloride, histidine, glutamic acid, aspartic acid, threonine, arginine, arginine, alanine, allantoin, proline, hydroxyproline, tyrosine, serine, taurine, glycine, phenylalanine, isoleucine, leucine, and valine. Among these, lysine hydrochloride, glutamic acid, aspartic acid, threonine, arginine, 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.

[0052] For methods 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 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 matching the solvent and amino acids, the texture of the configuration area RA becomes silky, making it easier to exert the skin moisturizing and barrier functions based on amino acids. For the mixture, the amino acids can be dissolved in the solvent, or the amino acids can be mixed in the solvent in a state that allows for separation. There are no particular limitations on the solvent, which 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 Fujifilm Wako 1st Grade. The ratio (by weight) of amino acids and solvent can be about 1:1 to 1:30.

[0053] The presence of amino acids can be evaluated, for example, using FZ / T 50049-2020 (Standard Test Methods for the Textile Industry of the People's Republic of China). In FZ / T 50049-2020, a colorimetric reaction can be performed after elution of amino acids with lithium hydroxide solution, followed by quantification using an amino acid analyzer. Alternatively, extraction can be performed using a solvent capable of eluting amino acids, followed by centrifugation and concentration to prepare the sample. The extracted amino acids can be processed using pre-column derivatization, and their peak intensity can be used to evaluate the presence or absence of amino acids.

[0054] At least one of the absorbent article 1 and the cover sheet 40 is provided with a display section 200 for associating with amino acids. The display section 200 can be provided in only one of the absorbent article 1 and the cover sheet 40, and may include at least one of an article display section 201 provided in the absorbent article 1 and a sheet display section 202 provided in the cover sheet 40. According to this method, since at least one of the absorbent article 1 and the cover sheet 40 is provided with a display section 200 for associating with amino acids, the user can visually recognize the presence of amino acids through the display section 200. Therefore, the user can identify the presence of amino acids and understand their effects before use, or be aware of the presence of amino acids during use, and easily experience the actual effects of amino acids.

[0055] The display section 200 can be any structure that allows the user to understand the presence of amino acids. Examples include text indicating amino acids, designs that evoke the image of amino acids, and text or images indicating the effects of amino acids. The display section 200 can be constructed by printing or by using embossing or other raised or recessed parts. Multiple display sections 200 can be provided in the absorbent article 1, the release liner 41, and the packaging sheet 42. By providing multiple display sections in the absorbent article 1, the release liner 41, and the packaging sheet 42, the user can more easily visually identify the display section 200 and more easily understand the presence of amino acids. The display section 200 of this embodiment has an article display section 201 and a sheet display section 202 provided in the packaging sheet 42. The article display section 201 is composed of a compression section 80. The article display section 201 is provided in the front region S1 and the rear region S2, respectively, and can be visually identified from the skin-side surface of the absorbent article 1. The article display section 201 has text indicating amino acids disposed between the double ring portions, and a design based on chemical structural formulas on the inner side of the ring portions. The sheet display section 202 is composed of a printing section printed on the packaging sheet 42. The sheet display section 202 may have the same design as the article display section 201.

[0056] The display unit 200 can be visually identified from the outside of the packaging 100. The outside of the packaging is the outside in its unopened state. The area RA containing the amino acids can be located on the skin-side surface of the absorbent article 1. The user can easily visually identify the outside of the packaging 100 when opening it or handling it, and can easily come into contact with the skin-side surface of the absorbent article 1 when wearing it. Since the display unit 200 and the amino acids are located on the part that the user observes or touches during wearing, the user can notice the presence of the amino acids and obtain their effects, and can easily experience the effects of the amino acids.

[0057] Here, regarding the structure where the display section 200 can be visually recognized from the outside of the packaging, the display section 200 can be attached to the outer surface of the packaging sheet 42, or it can be attached to the non-skin side of the release liner 41 or the absorbent article 1, allowing the display section 200 to be visually recognized even through the packaging sheet 42, etc. Furthermore, "able to visually recognize" in this utility model refers to the situation where a subject with good visual acuity (1.0 or better) can visually recognize an object when observing it at a distance of approximately 30cm to 50cm in a room with bright daylight white (color temperature standard 4600K to 5400K (Kelvin)) lighting (standard: 500x to 750x (lux)).

[0058] It is possible that the bending stiffness of the arrangement area RA in the absorbent article 1 is lower than the bending stiffness of the area where the article display 201 is provided. According to this method, the area where the article display 201 is provided has higher bending stiffness, is less prone to wrinkling, and can maintain the visual legibility of the article display 201. On the other hand, the bending stiffness of the arrangement area RA is lower, resulting in a soft skin-like feel, and can more effectively impart the effects of amino acids. Furthermore, in the case where the article display 201 and the arrangement area RA overlap, it is possible that the bending stiffness of the arrangement area RA where the article display 201 is not provided is lower than the bending stiffness of the area where the article display 201 and the arrangement area RA overlap. Alternatively, it is possible that the bending stiffness of the area where only the article display 201 is provided is higher than the bending stiffness of the area where the article display 201 and the arrangement area RA overlap. In the case where the article display 201 and the arrangement area RA are separated, it is possible to compare the bending stiffness of the area where only the article display 201 is provided with the bending stiffness of the arrangement area RA.

[0059] Here, bending stiffness can be measured using the KES method. Specifically, a KES-FB2-AUTO-A bending tester manufactured by KATO TECH Co., Ltd. can be used, and samples of measurable dimensions are prepared. Next, each sample is fixed between the chucks of the tester to measure the bending stiffness in the transverse direction. The sample is then bent towards the surface until the maximum curvature is +2.5 cm. -1 Next, bend towards the back side until the maximum curvature is -2.5cm. -1 The sample was then restored to its original state. The bending stiffness value was calculated based on the average of the slopes when bending began towards the surface with the bending moment relative to the curvature being approximately constant, and the slopes when bending began towards the back side with the bending moment relative to the curvature being approximately constant. This process was repeated 5 times for each sample, and the average value was taken as the bending stiffness.

[0060] It is possible that the bonding strength between the materials overlapping the configuration area RA is lower than the bonding strength between the materials in the area where the article display section 201 is located. According to this method, in the area where the article display section 201 is located, the bonding strength between the materials is higher, wrinkles are less likely to occur, and the visual legibility of the article display section can be maintained. On the other hand, in the configuration area RA, the bonding strength between the materials is lower, resulting in a soft, skin-like feel, which can more effectively impart the benefits of amino acids. When comparing the bonding strength between the materials, the same criteria as those for bending stiffness can be used for comparison.

[0061] The following methods can be used to compare the bond strength.

[0062] (1) Place the absorbent material in a constant temperature and humidity room (temperature 23±2℃, relative humidity 50±5%RH) for 24 hours.

[0063] (2) A sample of a self-absorbent article is formed having a joint portion of two sheets and a non-jointed portion of two sheets. Furthermore, the non-jointed portion is used as a clamping part of a fixture mounted on a tensile testing machine.

[0064] (3) The non-jointed portion is mounted on one clamp and the other clamp with a chuck distance of 25 mm and a width of 25 mm, and the joint portion is positioned between one clamp and the other clamp of the tensile testing machine. A T-peel test is performed on the sample at 25°C and a speed of 100 mm / min (if the width is not met, the maximum width can be used for comparison).

[0065] (4) Read the highest strength during the peeling of each sheet, i.e. the maximum strength.

[0066] (5) Measure the highest strength of the above for each different sample 10 times, and use the average value as the above bonding strength.

[0067] In addition, as a tensile testing machine, the Instron Japan 5900 series universal testing machine can be cited.

[0068] It is possible that the maximum width of the item display section 201 is longer than the maximum width of the placement area RA. Because the maximum width of the item display section 201 is longer, it is easier for the item display section 201 to be visible, and users can easily identify the presence of amino acids using the item display section 201. Furthermore, because the maximum width of the placement area RA is shorter, the effects of amino acids can be locally applied to the areas where amino acids are desired. For example, by placing amino acids in a manner that overlaps with the outer part of the absorbent core, effects can be applied to the groin area and the leg area, protecting the skin against friction caused by the legs, etc. In addition, the maximum width is the maximum length in the width direction W. The maximum width of the placement area RA can be the maximum width of one of the three placement areas RA. That is, the maximum width of the item display section 201 can be longer than the maximum width of a single placement area RA. Alternatively, the maximum width of the item display section 201 can be longer than the overall width of the placement area RA, including the three placement areas RA.

[0069] Alternatively, the item display section 201 may be located at the center of the absorbent article 1 in the width direction. Alternatively, the placement areas RA may be located on both sides of the item display section 201 in the width direction W. According to this method, the user can easily visually identify the item display section 201 located at the center of the absorbent article 1 in the width direction W, making it easier to understand the presence of amino acids. Furthermore, the outer part of the absorbent article 1 is more likely to come into contact with the legs. By placing amino acids in this area that is easily in contact with the legs, the skin barrier effect based on amino acids can be easily achieved. For the structure where the item display section 201 is located at the center of the absorbent article 1 in the width direction W, it is sufficient that the item display section 201 is placed at least partially in the central region of the area obtained by dividing the absorbent core 30 into three equal parts along the width direction W. Preferably, the item display section 201 can be placed across the center of the absorbent article 1 in the width direction W. Additionally, as long as at least partially of the placement areas RA are located on both sides of the item display section 201 in the width direction W, a portion of the placement areas RA may overlap with the item display section 201.

[0070] Alternatively, the main body fixing part 61 may be disposed overlapping the item display part 201 rather than the placement area RA. Since the item display part 201 is disposed overlapping the main body fixing part 61 and fixed to the garment, it is less prone to twisting during wear. Therefore, the shape of the item display part 201 is easily maintained, and its visual legibility is preserved. On the other hand, since the placement area RA does not overlap the main body fixing part 61, it is not fixed to the garment but easily follows the skin. Therefore, the placement area RA easily comes into contact with the skin, making it easier to deliver the benefits of amino acids to the user.

[0071] It is possible that at least a portion of the configuration area RA overlaps 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 providing the configuration area RA in an overlapping manner with the narrowing portion 31, amino acids can be imparted to the part that softly touches the skin, further enhancing the skin feel by utilizing both the softness to the skin and the efficacy of the amino acids.

[0072] The item display section 201 can be located further forward than the foremost item crease. In this embodiment, the item crease has a first crease F1 and a second crease F2, with the second crease F2 being the foremost crease. The area further forward than the foremost item crease is more easily visible to the user when they hold or visually recognize it while wearing the item. Therefore, the user can more easily perceive the presence of amino acids. Furthermore, generally, when folding an absorbent item with the item crease as a base, the fold is made from the last crease side, with the foremost crease being folded last. Therefore, when unfolding the absorbent item, the area further forward than the foremost item crease is unfolded first. This area, being unfolded first, is more easily visible to the user. By providing the item display section 201 in this easily visible area, the user can more easily perceive the presence of amino acids.

[0073] Alternatively, with the main wing folded, the placement area RA can be positioned outward in the width direction from the outer edge 62E of the main wing attachment portion 62. It is sufficient that at least a portion of the placement area RA is located outward in the width direction from the main wing attachment portion 62. When the main wing is attached to a garment, it is easy to fold it back towards the non-skin side of the garment using the crease from when it was folded back before use as a reference point. Therefore, the portion outward in the width direction from the outer edge of the main wing attachment portion is an area that easily floats towards the skin side when the main wing is rolled up around the garment. By providing the placement area in this easily floating area, amino acids can more easily come into contact with the skin.

[0074] The absorbent article, in a modified example, may have a hip flap and a flap fixing portion, the flap fixing portion being disposed on the hip flap and fixed to the skin side of the wearer. Alternatively, when the hip flap is folded back, the placement area may overlap with the flap fixing portion. When the hip flap is folded back, it is sufficient that at least a portion of the placement area overlaps with the flap fixing portion. With the hip flap folded back, the flap fixing portion and the placement area overlap, thus facilitating the transfer of amino acids to the skin side of the hip flap in the area overlapping with the flap fixing portion. During wear, the hip flap is disposed on the skin side of the wearer, and the area overlapping with the flap fixing portion is fixed to the wearer, making it easy to be pressed against the skin by the wearer. When pressed against the skin by the wearer, the amino acids transferred in the area overlapping with the flap fixing portion can come into contact with the skin.

The present invention can be implemented in modified and altered ways without departing from the spirit and scope of the present invention as defined by the claims.
