[0006] Problems to be solved by utility models

[0007] In Patent Document 1, the side panel is positioned between the skin-friendly side panel and the non-skin-friendly side panel, making it difficult for the user to notice its presence when visually examining the absorbent article from the skin-friendly side. Consequently, the user cannot fully grasp the leakage-prevention effect achieved by the side panel, and sometimes finds it difficult to obtain a sense of security relative to leakage.

[0008] This invention was made in view of the problem that provides an absorbent article in which the user can easily obtain a sense of security relative to leakage.

[0009] Solution for solving the problem

[0010] An absorbent article of one technical solution has: a planar direction including mutually orthogonal front-back and width directions; a thickness direction orthogonal to the planar direction; an absorbent body having an absorbent material for absorbing bodily fluids; and a pair of wings folded toward the non-skin side of the article. Each wing has: a skin-side sheet disposed on the skin-side surface of the wing; a non-skin-side sheet disposed on the non-skin-side surface of the wing; and a side sheet disposed between the skin-side sheet and the non-skin-side sheet across the wing and in an area overlapping with the absorbent body. The side sheet is water-repellent. The side sheet is colored to cover at least a portion of the skin-side of the absorbent body.

[0011] Summary of Implementation Methods

[0012] From the description in this specification and the accompanying drawings, at least the following matters become clear.

[0013] Technical Solution 1 discloses an absorbent article comprising: a planar direction including mutually orthogonal front-back and width directions; a thickness direction orthogonal to the planar direction; an absorbent body having an absorbent material for absorbing bodily fluids; and a pair of wings folded toward the non-skin side of the article. Each wing has: a skin-side panel disposed on the skin-side surface of the wing; a non-skin-side panel disposed on the non-skin-side surface of the wing; and a side sheet disposed between the skin-side panel and the non-skin-side panel across the wing and in an area overlapping with the absorbent body. The side sheet is water-repellent. The side sheet is colored and covers at least a portion of the skin-side of the absorbent body. According to this technical solution, because the side sheet is water-repellent and covers the skin-side of the absorbent body, the transfer of bodily fluids absorbed by the absorbent body to the skin-side surface of the absorbent article can be inhibited, and leakage of bodily fluids can be suppressed by using the side sheet. The side sheet is colored, making it easily visible. The user can perceive the presence of the side sheet disposed across the wing and the absorbent body. The presence of side panels allows for visual assessment of the effectiveness of the wings in preventing bodily fluid leakage, providing a sense of reassurance in the face of potential leaks.

[0014] According to the preferred technical solution, the utility model of technical solution 2 can have the following features as in the utility model of technical solution 1. The absorbent article is provided with a main compression section that compresses the skin side sheet, the absorbent body, and the side sheet. Since the main compression section is formed by compressing the skin side sheet, the absorbent body, and the side sheet, the visual visibility of the side sheet in the area where the main compression section is provided is improved. The user can more easily perceive the presence of the side sheet. Furthermore, the main compression section can be used to introduce bodily fluids to the non-skin side, thus suppressing bodily fluid leakage.

[0015] According to the preferred technical solution, the utility model of technical solution 3 can have the following features as in the utility model of technical solution 2. The main compression portion spans the inner edge of the side plate in the width direction. According to this technical solution, the inner edge of the side plate is easily visible. Users can easily grasp the area where the side plate is located and easily obtain a sense of security relative to leakage.

[0016] According to the preferred technical solution, the utility model of technical solution 4 can have the following features in any of the utility models of technical solutions 1 to 3. A folded portion is provided on the inner side of the side sheet in the width direction, formed by folding the side sheet in the thickness direction. According to this technical solution, two layers of water-repellent side sheets are stacked in the area where the folded portion is provided. Therefore, the leakage suppression effect of body fluids achieved by the side sheets can be further improved.

[0017] According to the preferred technical solution, the utility model of technical solution 5 can have the following features in any of the utility models of technical solutions 1 to 4. The thickness of the skin-side sheet is greater than the thickness of the side sheet. According to this technical solution, because the skin-side sheet is thicker and the side sheet is thinner, the height difference caused by the edge of the side sheet is less likely to be transmitted to the wearer due to the thickness of the skin-side sheet, thus suppressing any discomfort caused by the presence of the side sheet. Because the skin-side sheet is relatively thick, when the wing is folded to the non-skin side of the garment, the skin-side sheet can be securely wrapped around the garment, stabilizing the position of the absorbent garment during wear and suppressing leakage caused by the twisting of the absorbent garment.

[0018] According to the preferred technical solution, the utility model of technical solution 6 can have the following features in any of the utility models of technical solutions 1 to 5. A wing compression portion is provided in the wing portion, which is formed by compressing the skin side sheet, the side sheet, and the non-skin side sheet in the thickness direction, and is arranged along the front-back direction. According to this technical solution, the visual recognizability of the side sheet in the area where the wing compression portion is provided is improved. The user can more easily perceive the presence of the side sheet. Furthermore, because of the wing compression portion arranged along the front-back direction, even if bodily fluids diffuse into the wing, the bodily fluids can be introduced into the wing compression portion within a certain range extending along the front-back direction of the wing, thus suppressing bodily fluid leakage.

[0019] According to the preferred technical solution, the utility model of technical solution 7 can have the following features in any of the utility models of technical solutions 1 to 6. The outer edge of the side plate in the front-rear direction is located on the outer side in the front-rear direction, which is further outward than the outer edge of the wing compression portion in the front-rear direction. According to this technical solution, even if body fluid diffuses in the front-rear direction via the wing compression portion provided along the front-rear direction, the side plate can still be used to suppress leakage because it is disposed in the area where the body fluid diffuses.

[0020] According to the preferred technical solution, the utility model of technical solution 8 can have the following features in any of the utility models of technical solutions 1 to 7. The outer edge of the side piece in the width direction is located at the outer edge of the wing in the width direction. According to this technical solution, the side piece can exert a water-repellent effect over the entire area of ​​the wing in the width direction, and can suppress the leakage of bodily fluids over the entire area of ​​the wing in the width direction. Furthermore, the side piece can be used to increase the stiffness of the entire area of ​​the wing in the width direction, suppressing the twisting of the wing and suppressing leakage caused by the twisting of the wing.

[0021] According to the preferred technical solution, the utility model of technical solution 9 can have the following features in any of the utility models of technical solutions 1 to 8. The skin-side sheet is a top sheet, which is disposed at a position closer to the skin than the absorbent body, abutting against the wearer's skin. According to this technical solution, when the wings are folded, the top sheet easily contacts the leg, improving skin feel. Because the top sheet is disposed across the skin side and wings of the absorbent body, the edge of the sheet is not exposed on the skin-side surface of the absorbent article, thus preventing leakage of bodily fluids from the edge of the sheet.

[0027] Overall structure of absorbent items

[0028] Hereinafter, the absorbent article 1 according to the embodiments will be described with reference to the accompanying drawings. Figure 1 This is a schematic plan view of the absorbent article 1 as seen from the skin side T1 according to the embodiment. Figure 2 It is along Figure 1 The cross-sectional view shown along line AA. Figure 2 For ease of explanation, the components constituting absorbent article 1 are partially separated in the thickness direction; however, in the actual product, there are portions where the components are joined together. Furthermore, in the following drawings, similar or identical reference numerals are used to label the same or similar parts. However, it should be noted that the drawings are schematic, and the proportions of the dimensions may differ from reality. Therefore, specific dimensions should be determined by referring to the following explanation. Additionally, the drawings may contain portions with different dimensional relationships or proportions.

[0029] Examples of absorbent articles 1 include urine-absorbing pads, sanitary napkins, and panty liners. The absorbent article 1 of this embodiment is primarily designed to absorb urine; it is neither primarily designed to absorb menstrual blood like sanitary napkins, nor primarily designed to absorb vaginal secretions like panty liners. The absorbent article 1 can be an absorbent article worn with underwear or other clothing.

[0030] The absorbent article 1 has a planar direction including mutually orthogonal front-to-back directions L and width directions W, and a thickness direction T orthogonal to the planar direction. The thickness direction T extends from the skin side T1 to the non-skin side T2. The skin side T1 corresponds to the side facing the wearer's skin when in use. The non-skin side T2 corresponds to the side opposite to the skin side T1 when in use, that is, the side facing the opposite direction to the wearer's skin. The absorbent article 1 has a central region S1, a front region S2, and a rear region S3. The central region S1 is the region disposed opposite to the wearer's excretory opening (urination opening). When the absorbent article 1 is worn as an underwear, the central region S1 is the region disposed in the crotch area of ​​the underwear and between the wearer's legs. The front region S2 is located in a position further forward than the central region S1. The rear region S3 is located in a position further back than the central region S1. The central region S1 is composed of a region with wings 40 disposed thereon.

[0031] Furthermore, in this invention, the outer portion refers to the part occupying a certain range in the width direction W, including the outer edge in the width direction W. 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 the edge formed by connecting the points located on the outer side in the width direction W within the entire range of 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 in the width direction W. 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 the edge formed by connecting the points located on the inner side in the width direction W within the entire range of 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 in the front-rear direction L, i.e., the outer end edges. 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 end edge includes the front edge and the rear edge. Furthermore, in this specification, the term "along the front-to-back direction L" means a direction with an angle of less than 45° relative to the front-to-back direction L, and the term "along the width direction W" means a direction with an angle of less than 45° relative to the width direction W.

[0032] The absorbent article 1 may have at least an absorbent body 30, a top sheet 10, and a back sheet 20. The top sheet 10 covers the skin side T1 of the absorbent body 30 and comes into contact with the wearer's skin. The top sheet 10 is liquid-permeable and may be made of, for example, hot-air nonwoven fabric. The back sheet 20 is positioned at a position closer to the non-skin side T2 of the absorbent body 30. The back sheet 20 is liquid-impermeable and may be made of a membrane. A fixing portion 60 for securing the absorbent article 1 to the wearable article may be provided on the non-skin side of the back sheet 20. The fixing portion 60 may have a main fixing portion 61 disposed at least in the area overlapping with the absorbent body 30 and a wing fixing portion 62 disposed in the wing portion 40. An adhesive or mechanical hook may be provided in the fixing portion 60. In this embodiment, the main fixing portion 61 and the wing fixing portion 62 extend in the width direction W and are disposed spaced apart in the front-rear direction L. In a modified example, the main body fixing part 61 and the wing fixing part 62 can extend along the front-rear direction L and are arranged at intervals in the width direction W.

[0033] The absorbent body 30 is disposed between the top sheet 10 and the back sheet 20. The absorbent body 30 has an absorbent material for absorbing bodily fluids. The absorbent material includes fibers such as pulp and highly absorbent polymers. The absorbent body 30 may have multiple absorbent layers. The absorbent body 30 may have an upper absorbent layer 31 and a lower absorbent layer 32 disposed on a non-skin side of the upper absorbent layer 31. The absorbent materials of the upper absorbent layer 31 and the lower absorbent layer 32 may include both fibers and highly absorbent polymers. The absorbent body 30 may have an intermediate absorbent layer 33 disposed between the upper absorbent layer 31 and the lower absorbent layer 32. The absorbent material of the intermediate absorbent layer 33 may contain fibers but not highly absorbent polymers.

[0034] The upper absorbent layer 31 may have multiple sheets and a highly absorbent polymer disposed between the sheets. That is, the upper absorbent layer 31 may be a so-called SAP sheet. The highly absorbent polymer may be bonded to the sheets by fusing multiple sheets together, rather than using an adhesive. That is, the upper absorbent layer 31 may not have an adhesive such as an adhesive or solvent to bond the absorbent material. For the upper absorbent layer 31 of this embodiment, the highly absorbent polymer is sandwiched in a hot-air nonwoven fabric and the hot-air nonwoven fabric is heat-treated, thereby using the melting of the fibers of the hot-air nonwoven fabric to fuse the highly absorbent polymer to the hot-air nonwoven fabric.

[0035] The lower absorbent layer 32 can be cured by the entanglement of fibers without being bonded by an adhesive. That is, the lower absorbent layer 32 may not have an adhesive such as a binder for bonding the absorbent material. The absorbent layer cured by the entanglement of fibers can be manufactured, for example, by forming a fiber laminate using a dry or wet method and then pressing it with a heated roller, or by welding it using air heating, or by interlacing the fibers using a high-pressure water jet. The lower absorbent layer 32 of this embodiment is an absorbent layer formed by processing a highly absorbent polymer and fibers using a wet web forming process (wet method). According to the absorbent layer manufactured using the wet web forming process, there are fewer gaps between the fibers, which can suppress the expansion of the highly absorbent polymer, thereby preventing the absorbent layer from becoming too thick.

[0036] The intermediate absorbent layer 33 is laminated with fibers such as pulp and highly absorbent polymers. An opening 34 extending through the intermediate absorbent layer 33 along its thickness direction can be formed. The opening 34 is centrally located across the width direction W of the central region S1 of the absorbent article 1. The central region S1 of the absorbent article 1 is a region easily positioned opposite an excretion opening and easily guided towards it. According to this technical solution, the transfer of bodily fluid from the upper absorbent layer 31 to the lower absorbent layer 32 can be facilitated via the opening 34 of the intermediate absorbent layer 33. The opening 34 is formed when the unit area weight of the fibers in the absorbent material is 0 g / m². 2 This part. Furthermore, the fiber's area weight is 0 g / m². 2 For the portion where the design unit area weight is 0g / m², 2 Alternatively, fibers can be arranged to spread out from the surrounding area. Furthermore, a highly absorbent polymer can be arranged at the opening 34 in this embodiment.

[0037] The absorbent article 1 may be provided with a main compression section 80 formed by compressing the top sheet 10 and the absorbent body 30 in the thickness direction T. In this embodiment, the main compression section 80 may have a first central compression section 81, a second central compression section 82, and end compression sections 83. The first central compression section 81 is arranged in a dot-like pattern at the center of the absorbent article 1 in the width direction. Multiple first central compression sections 81 are arranged at intervals in the front-rear direction L and the width direction W. The second central compression section 82 overlaps with the outer portion of the central region S1 of the absorbent body 30 and has an arc shape extending in the front-rear direction L. The end compression sections 83 are disposed at the corners of the four corners of the absorbent body.

[0038] The absorbent article 1 may have a pair of wings 40 that extend outward in the width direction W of the absorbent body 30 and are folded toward the non-skin side of the underwear when worn. Figure 3 yes Figure 1An enlarged view of section C is shown. A pair of wings 40 may be provided spaced apart in the width direction W. The wings 40 may be positioned in the central region S1, with the leading edge 40F of the wings 40 forming the leading edge of the central region S1 and the trailing edge 40R of the wings 40 forming the trailing edge of the central region S1. The leading edge 40F and the trailing edge 40R of the wings are defined by the inner edge of the wings. The inner edge of the wings 40 is the portion of the wings that is recessed inward in the width direction. Each wing 40 may have a skin-side plate 41 disposed on the skin-side T1 surface of the wing 40, a non-skin-side plate 42 disposed on the non-skin-side T2 surface of the wing 40, and a side plate 45 disposed between the skin-side plate 41 and the non-skin-side plate 42. The side plate 45 is disposed across the wing 40 and the area overlapping with the absorber 30. The structure of the side plate 45 will be described in detail later.

[0039] The absorbent article 1 may not be linearly symmetrical when its axis of symmetry is a first centerline 1CW extending along the front-rear direction L from its center in the width direction W. That is, the absorbent article 1 may be asymmetrical from left to right when viewed from above. Furthermore, the absorbent article 1 may not be linearly symmetrical when its axis of symmetry is a second centerline 1CL extending along the width direction W from its center in the front-rear direction L. That is, the absorbent article 1 may be asymmetrical from front to back when viewed from above.

[0040] A tab 50 extending outward when viewed from above may be provided at the outer end of the absorbent article 1 in the front-rear direction L. The tab 50 is a portion that bulges outward toward the outside of the absorbent article 1. Because the absorbent article 1 has the tab 50, the wearer can remove the absorbent article 1 from the underwear by grasping the tab 50 after use. In this embodiment, the tab 50 is provided only on one side of the front end of the absorbent article 1 with respect to the first center line 1CW, and is not provided at the rear end of the absorbent article 1. However, in modified examples, the tab 50 may be provided on both sides of the front end of the absorbent article 1 with respect to the first center line 1CW, may be provided at both the front and rear ends of the absorbent article 1, or may be provided only at the rear end of the absorbent article 1.

[0041] An outer edge compression portion 90 may be provided in the absorbent article 1. This outer edge compression portion 90 is arranged along the outer edge of the absorbent article 1 and is formed by compressing the sheets arranged on the outer edge of the absorbent article 1 together. Multiple outer edge compression portions 90 are arranged at intervals along the outer edge of the absorbent article 1 in the planar direction. The outer edge compression portions 90 may be arranged at the outer end in the front-rear direction L of the absorbent article, the outer side of the front region S2, the outer side of the rear region S3, the side portion of the wing 40 extending outward in the width direction, and the outer side portion of the wing 40. The outer edge compression portion 90 may be a portion formed by compressing the top sheet 10 and the back sheet 20, or a portion formed by compressing the skin-side sheet 41 and the non-skin-side sheet 42.

[0042] The absorbent article 1 of this embodiment is configured to provide the user with a sense of security regarding leakage. Next, the structure for providing the user with a sense of security regarding leakage will be described in detail. The side sheet 45 may be water-repellent. The water-repellent side sheet 45 may be made of a sheet that has undergone a water-repellent treatment. Alternatively, the water-repellent side sheet 45 may be made of a sheet with a higher degree of water repellency than the skin side sheet 41. The degree of water repellency can be measured and compared using the following method. Five sheets of filter paper are stacked and placed on a horizontal table, and a sample is placed on them. A drop of artificial urine (approximately 0.05 g) is dripped onto point 20 using a pipette (first time). After dripping from point 20, the sample is left for 30 seconds, and then the areas where the sample has been absorbed by the filter paper are counted. After confirming that the sample after the first absorption is completely dry, a drop of artificial urine (approximately 0.05 g) is dripped onto point 20 at the same area as the first drip (second time). After confirming that the sample was completely dry after the second absorption, a drop of artificial urine (approximately 0.05 g) was applied to point 20 at the same location as the second application (the third application). The number of absorption sites from the first to the third application was measured. A lower number indicates higher water repellency, and a higher number indicates lower water repellency.

[0043] The side sheet 45 is colored. The side sheet 45 can be colored by applying a colorant (ink, etc.) to the side sheet 45, or by allowing the colorant to penetrate into the material constituting the side sheet 45 (fiber, adhesive, etc.). The side sheet 45 covers at least a portion of the skin side T1 of the absorber 30. In this embodiment, the side sheet 45 covers the outer side of the absorber 30 but does not cover the center in the width direction W of the absorber 30. Therefore, an area of ​​the absorber 30 whose skin side is not covered by the side sheet 45 is provided between the left and right side sheets 45.

[0044] The side panel 45 is water-repellent and covers the skin side of the absorbent body 30, thus preventing the transfer of bodily fluids absorbed by the absorbent body 30 to the skin side T1 of the absorbent article 1, and inhibiting the leakage of bodily fluids. The side panel 45 is colored for easy visibility. The user can perceive the presence of the side panel 45, which is positioned across the wing 40 and the absorbent body 30. The presence of the side panel 45 allows the user to visually perceive the effect of inhibiting bodily fluid leakage at the wing 40, providing a sense of reassurance against potential leakage.

[0045] The main compression section 80 can be formed by compressing the skin side sheet 41, the absorbent body 30, and the side sheet 45. In this embodiment, the second central compression section 82 is formed by compressing the skin side sheet 41, the absorbent body 30, and the side sheet 45, constituting the main compression section of this invention. Since the main compression section 80 is formed by compressing the skin side sheet 41, the absorbent body 30, and the side sheet 45, the visual visibility of the side sheet 45 in the area where the main compression section 80 is provided is improved. Users can more easily perceive the presence of the side sheet 45. Furthermore, the main compression section 80 can be used to introduce bodily fluids to the non-skin side T2, thus suppressing bodily fluid leakage.

[0046] The main compression portion 80 can extend across the inner edge 45I of the side plate 45 in the width direction. According to this technical solution, the inner edge 45I of the side plate 45 is easily visible. Users can easily grasp the area where the side plate 45 is located and easily obtain a sense of security relative to leakage. In this embodiment, the second central compression portion 82 is an arc shape that bulges inward in the width direction W when viewed from above, and the front end and rear end of the second central compression portion 82 extend across the inner edge 45I of the side plate 45 in the width direction. The second central compression portion 82 extends across the area that overlaps with the side plate 45 and the area that does not overlap with the side plate 45.

[0047] The thickness of the skin-side sheet 41 can be greater than the thickness of the side sheet 45. This thickness is the thickness of the absorbent article 1 in its natural state. The natural state refers to the state of the absorbent article 1 after it has been removed from the packaging and placed in an atmosphere of 20℃±2℃ and 60%±5%RH for 24 hours. Because the skin-side sheet 41 is thicker and the side sheet 45 is thinner, the height difference caused by the edge of the side sheet 45 is less likely to be transmitted to the wearer due to the thickness of the skin-side sheet 41, thus suppressing any discomfort caused by the presence of the side sheet 45. Because the skin-side sheet 41 is thicker, when the wing 40 is folded over to the non-skin-side T2 of the garment, the skin-side sheet 41 can be securely wrapped around the garment, stabilizing the position of the absorbent article 1 during wear and suppressing leakage caused by the twisting of the absorbent article 1.

[0048] A wing compression section 70 may be provided on the wing portion 40. This wing compression section 70 is formed by compressing the skin side sheet 41, side sheet 45 and non-skin side sheet 42 in the thickness direction T, and is arranged along the front-rear direction. The wing compression section 70 has a predetermined shape such as rectangle or circle, and multiple wing compression sections 70 are arranged at intervals in the planar direction. It is sufficient that the wing compression sections 70 are arranged at least at intervals in the front-rear direction L, but multiple wing compression sections 70 may also be arranged at intervals in the width direction W.

[0049] By providing the wing compression section 70, the visual visibility of the side panel 45 in the area where the wing compression section 70 is located is improved. Users can more easily perceive the presence of the side panel 45. Furthermore, because the wing compression section 70 is provided along the longitudinal direction L, even if bodily fluids diffuse into the wing 40, the bodily fluids can be introduced into the wing compression section 70 within a certain range extending along the longitudinal direction L of the wing 40, thus suppressing bodily fluid leakage.

[0050] The outer edge of the side plate 45 in the longitudinal direction can be located on the outer side of the outer edge of the wing compression section 70 in the longitudinal direction. Specifically, the front edge 45F of the side plate 45 can be located on the front side of the front edge 70F of the wing compression section 70, or the rear edge 45R of the side plate 45 can be located on the rear side of the rear edge 70R of the wing compression section 70, or both outer edges of the side plate 45 in the longitudinal direction can be located on the outer side of both outer edges of the wing compression section 70 in the longitudinal direction. According to this technical solution, even if bodily fluid diffuses in the longitudinal direction L via the wing compression section 70 provided along the longitudinal direction L, the side plate 45 is positioned in the area where the bodily fluid diffuses, thus achieving the effect of suppressing leakage.

[0051] The wing compression portion 70 can be provided over 50% or more of the entire area in the longitudinal direction L of the wing 40, preferably over 80%. The entire area in the longitudinal direction L of the wing 40 is the region from the leading edge 40F of the wing 40 to the trailing edge 40R of the wing 40. The leading edge 70F of the wing compression portion 70 can be located rearward of the leading edge 40F of the wing 40. Additionally, the leading edge 45F of the side panel 45 can be located rearward of the leading edge 40F of the wing 40. The trailing edge 70R of the wing compression portion 70 can be located forward of the trailing edge 40R of the wing 40. Additionally, the trailing edge 45R of the side panel 45 can be located forward of the trailing edge 40R of the wing 40. According to this technical solution, bodily fluids are unlikely to reach the root of the wing 40, thus suppressing leakage from the root of the wing 40.

[0052] The outer edge of the side piece 45 in the width direction W can be located at the outer edge of the wing 40 in the width direction W. That is, the side piece 45 can be disposed over the entire area in the width direction W of the wing 40. According to this technical solution, the water-repellent effect of the side piece 45 can be achieved over the entire area in the width direction of the wing 40, and leakage of bodily fluids can be suppressed over the entire area in the width direction of the wing 40. In addition, the side piece 45 can be used to increase the stiffness of the entire area in the width direction of the wing 40, suppress the torsion of the wing 40, and suppress leakage caused by the torsion of the wing 40.

[0053] The skin-side sheet 41 disposed on the wing 40 can be the top sheet 10. That is, the top sheet 10 can be disposed across the area covering the skin-side T1 of the absorbent 30 and the wing 40. The top sheet 10 can be disposed over the entire area of ​​the absorbent article 1, located at the position closest to the skin in the thickness direction T of the absorbent article 1. According to this technical solution, when the wing 40 is folded, the top sheet 10 can easily come into contact with the leg, thereby improving the skin feel. Since the top sheet 10 is disposed across the skin-side T1 of the absorbent 30 and the wing 40, the edge of the sheet is not exposed on the skin-side T1 surface of the absorbent article 1, thereby suppressing the leakage of bodily fluids from the edge of the sheet.

[0054] The non-skin side sheet 42 disposed on the wing 40 can be a back sheet 20. That is, the back sheet 20 can be disposed across the area covering the non-skin side T2 of the absorbent 30 and the wing 40. The back sheet 20 can be disposed over the entire area of ​​the absorbent article 1, and is located at the position closest to the non-skin side T2 in the thickness direction T of the absorbent article 1.

[0055] The inner edge 45I of the side sheet 45 is located inside the outer edge of the absorber 30 in the width direction W. The length in the width direction of the area where the side sheet 45 overlaps with the absorber 30 is not limited, but can be 5 mm or more and 10 mm or less. Alternatively, the inner edge 45I of the side sheet 45 may not be folded in the thickness direction T, and the thickness of the side sheet 45 may be constant throughout the entire area where the side sheet 45 is disposed.

[0056] In a modified example, a folded portion may be provided on the inner side of the side sheet 45 in the width direction, formed by folding the side sheet 45 in the thickness direction. The folded portion may be a part of the side sheet 45 folded towards the skin side T1 or the non-skin side T2 with a crease extending in the front-back direction L as a base point. According to this technical solution, two layers of water-repellent side sheets are stacked in the area where the folded portion is provided. Therefore, the leakage inhibition effect of body fluids achieved by the side sheets can be further improved.

[0057] The present invention has been described in detail above using the embodiments described above. However, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modified and altered technical solutions without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes only and does not have any restrictive meaning regarding the present invention.
