Description

Absorbent article

The present invention relates to an absorbent article which is colored.

As a type of disposable diaper which is an absorbent article, there are known pant-type disposable diapers having an absorbent body and an outer body disposed on a side farther away from the wearer's body than the absorbent body. Patent Document 1 discloses that, in the shorts type disposable diaper having this structure, the outer body includes an outer layer sheet which forms an outer surface of the diaper in a worn state, and a face-to-face confrontation with the skin of the outer layer sheet. The inner layer sheet is arranged, and the outer layer sheet has a larger length in the longitudinal direction of the wearer than the inner layer sheet, and the extension of the outer layer sheet from the longitudinal end edge of the inner layer sheet The exit portion is folded back toward the skin-facing surface of the inner sheet and fixed to the skin-facing surface. The folded-back portion of the outer layer sheet is one of the typical structures of the shorts-type disposable diaper, and the folded-back portion is usually joined to a surface facing the folded-back portion. In addition, generally, absorbent articles such as disposable diapers are white. In contrast, the shorts-type disposable diaper described in Patent Document 1 describes that the outer layer sheet and the inner layer sheet constituting the outer body are relatively close to the wearer in order to improve the designability of the appearance similar to that of an undergarment. The overall coloring of the inner sheet of the skin is chromatic color. Prior Art Literature Patent Literature Patent Literature 1: Japanese Patent No. 5695789

The present invention is an absorbent article which has a longitudinal direction corresponding to the front and back direction of the wearer and a transverse direction orthogonal to the wearer's side, and has a lower part of the crotch and a ventral part and a dorsal part extending longitudinally from the front part of the crotch part. An absorber is provided from the ventral portion to the dorsal portion. On the ventral portion or the dorsal portion, the skin closest to the wearer's skin is closest to the sheet so as to extend laterally on the skin-opposing surface of the body portion forming the ventral portion or the dorsal portion. Way configuration. The non-skin-facing surface of the skin closest to the sheet has a joint portion and a non-joint portion that are opposite to the non-skin-facing surface, and has a colored portion and Coloring department. The non-joined portion is located in an end region including the longitudinal edge of the skin closest to the sheet, and includes the non-colored portion.

The skin-facing side of the wearer's waist and the waist area near it is always in contact with the abdomen or back of the wearer, and there are more opportunities to touch with the fingers, so it is better to have a good texture and there is room for improvement . In addition, disposable diapers and other absorbent articles show their true value when they are worn in the correct wearing position. However, the current situation is that positioning is not easy when wearing, and it is not necessary to wear in the correct wearing position. Therefore, the subject of the present invention is to provide an absorbent article that is colored and has high design properties, has a good texture on the opposite side of the skin, and has simple positioning when worn. Hereinafter, the present invention will be described based on a preferred embodiment of the present invention with reference to the drawings. 1 to 4 show a diaper 1A as an example of a shorts type disposable diaper which is one embodiment of the absorbent article of the present invention. The diaper 1A has a longitudinal direction X corresponding to the front and back direction of the wearer and a transverse direction Y orthogonal thereto, and has a lower crotch portion B, and a ventral portion A and a back portion C extending from the lower crotch portion B in the longitudinal direction X. An absorbent body 23 is provided that extends from the ventral portion A to the dorsal portion C and extends in the longitudinal direction X and is capable of absorbing and retaining body fluids that have been excreted. The lower part B is placed on the crotch portion of the wearer in the wearing state of the diaper 1A, and the ventral part A is placed on the ventral side of the wearer than the lower part B in the wearing state of the diaper 1A. The back side portion C is located in a worn state of the diaper 1A at a position closer to the back side of the wearer than the lower portion B, that is, the rear side. The diaper 1A includes: an absorbent body 2 having an absorbent body 23; and an exterior body 3 disposed on a side farther away from the wearer's body than the absorbent body 2; each of a ventral portion A and a dorsal portion C The side edges AS, CS of both sides along the longitudinal direction X of the exterior body 3 are joined to each other by a well-known joining method such as an adhesive, heat sealing, and ultrasonic sealing, thereby forming a pair of sides as shown in FIG. 1. The seal portions S, S, and the waist opening WW through which the wearer's waist passes, and the pair of leg openings LH and LH through which the wearer's lower limbs pass. As shown in FIG. 2, the diaper 1A is divided into the front side (ventral side) of the wearer's body in the wearing state based on the longitudinal centerline CLx that divides the diaper 1A in the longitudinal direction X and bisects the transverse direction Y. The figure F and the figure R covering the back side (back side) of the wearer's body in the wearing state. The ventral part A is a part of the front body piece F, the dorsal part C is a part of the rear body piece R, and the lower part B is present across the front body piece F and the rear body piece R. Both the ventral portion A and the backside portion C are located in the same position as the side seal portion S in the longitudinal direction X, and are arranged around the waist of the wearer's waist in the wearing state of the diaper 1A. The lower part B is an area where the leg openings LH and LH forming recessed portions are formed on the edge portions of both sides of the exterior body 3 along the longitudinal direction X. The lower part B has an excretory portion facing the wearer's excretory portion (penis, etc.) in the wearing state of the diaper 1A. The excretory portion facing portion is usually located in the central portion (longitudinal center) of the longitudinal X of the diaper 1A On line CLx) or near it. The absorptive body 2 has a rectangular shape in plan view as shown by the outline in FIG. 2, extending from the ventral portion A to the dorsal portion C and extending in the longitudinal direction X, so that the longitudinal direction and the longitudinal direction of the diaper 1A in the expanded and extended state X is uniform, and it is arrange | positioned in the center part of the lateral Y of the exterior body 3, and is joined to the exterior body 3 by an adhesive agent. As shown in FIG. 2, the absorptive body 2 includes a front sheet 21 that forms a liquid-permeable surface facing the skin, and a back sheet 22 that forms a liquid-impermeable or liquid-impermeable or water-repellent liquid that is not a skin-facing surface. And the liquid-retaining absorber 23 disposed between the two sheets 21 and 22 are integrally formed by a known bonding method such as an adhesive. The absorbent body 23 has a rectangular shape in plan view and forms the outer shape of the absorbent body 2. As shown in FIG. As the front sheet 21, the back sheet 22, and the absorber 23, various materials previously used in such absorbent articles can be used without particular limitation. For example, as the front sheet 21, various nonwoven fabrics or perforated films can be used, and as the back sheet 22, a resin film or a laminated film of a resin film and a nonwoven fabric can be used. As the absorbent body 23, an aggregate having a fibrous material such as pulp fibers or an absorbent core composed of water-absorbing polymer particles can be used, and the outer surface of the absorbent core may be covered with a liquid-permeable core material. . In this specification, the "skin-facing side" refers to the surface of the absorbent article or its constituent members (for example, the absorbent body) that faces the skin side of the wearer when worn, that is, the skin that is relatively close to the wearer. The "non-skin-facing side" refers to the side of the absorbent article or its constituent member that faces the side opposite to the skin (wearing side) when the absorbent article is worn, that is, the side that is relatively far from the wearer's skin . In addition, the "when wearing" as used herein refers to a state in which a generally appropriate wearing position is maintained, that is, a correct wearing position of the absorbent article, and does not include a case where the absorbent article is deviated from the wearing position. . As shown in FIG. 2, on the skin-facing side of the absorptive body 2, a pair of leak-proof sheets made of liquid-resistant or water-repellent and breathable sheets are provided on the left and right sides along the longitudinal direction X. Edge 24, 24. In the vicinity of the free end portion of each leak-proof burr 24, one or more elastic members 25 for linear leak-proof burr formation are arranged in an extended state. The leak-proof flanging 24 is configured such that the elastic member 25 arranged in an extended state contracts at the time of wearing the diaper 1A to stand at least below the crotch portion B, thereby preventing the excretion liquid such as urine from flowing out of the lateral Y. The exterior body 3 is a main body portion forming the outer shape of the diaper 1A, and naturally is also a main body portion forming the outer shape of each of the ventral portion A, the lower crotch portion B, and the back portion C. That is, the outer body 3 has the largest area among all the constituent members of the diaper 1A, and forms the outer shape of the diaper 1A in an expanded and extended state as shown in FIG. 2, and the periphery of the outer body 3 forms the outline of the diaper 1A in this state. That is, the outline of each of the ventral portion A, the lower iliac crest B, and the dorsal portion C. The so-called "expanded and extended state" of the diaper 1A means that the diaper 1A is separated from the side seal portion S to become the unfolded state, and the elastic member of each portion is extended to expand the unfolded diaper 1A to the design size (as opposed to completely excluded The state when the elastic member is expanded into a flat shape under the influence of the elastic member). The exterior body 3 is shown in the expanded and extended state as shown in FIG. 2, and has a rectangular shape in which the length of the transverse Y is longer than the length of the longitudinal X on the ventral portion A and the dorsal portion C. A pair of leg portions LS, LS, which are edges of both sides along the longitudinal direction X of the exterior body 3 between the lower portion B between the back portions C, are curved into an arc shape protruding toward the center of the lateral direction Y. The outer body 3 forming the outer shape of the diaper 1A has the plan view shape in an unfolded and extended state, whereby the plan view shape of the diaper 1A in the same state is shown in FIG. Hourglass-like shrinking. As shown in FIG. 3, the exterior body 3 is constituted by a laminated body including an outer layer sheet 31 and an inner layer sheet 32. The outer layer sheet 31 forms the outer surface of the diaper 1A, that is, the non-skin facing surface, in a worn state. The inner-layer sheet 32 and the skin-facing surface 31a of the outer-layer sheet 31 are arranged to face each other. That is, this laminated system forms a main body portion outside the diaper 1A, and also forms a main body portion outside each of the ventral portion A, the lower crotch portion B, and the back side portion C. The outer sheet 31 is a constituent member located farthest from the wearer's skin among all constituent members of the diaper 1A. The inner layer sheet 32 is located closer to the wearer's body than the outer layer sheet 31, and the inner surface of the diaper 1A, that is, the skin-opposing surface, is formed in the worn state. The outer layer sheet 31 and the inner layer sheet 32 are bonded to each other at a specific position by an adhesive 35. As the outer layer sheet 31 and the inner layer sheet 32, various materials previously used as an exterior body in this absorbent article can be used without particular limitation, and examples thereof include spunbond nonwoven fabric, hot-air nonwoven fabric, and needle-punched nonwoven fabric. Non-woven fabric formed by various manufacturing methods. As shown in FIG. 1 to FIG. 3, for forming a pair of leg openings LH and LH, the leg edge LS of each of the opening edges, a linear or band-shaped one or plural leg folds are formed. The leg elastic members 33 are arranged in an extended state, thereby forming a substantially continuous loop-shaped leg fold over the entire periphery of the opening edge of each of the pair of leg openings LH and LH. Further, in each of the ventral portion A and the dorsal portion C, the linear or band-shaped waist elastic member 34 is disposed at a portion including the waist circumference of the wearer of the waist, and a plurality of the elastic members 34 are arranged in an extended state in the transverse direction Y. The plurality of waist elastic members 34 are arranged intermittently at a certain interval in the longitudinal direction X. The waist elastic member 34 extends over substantially the entire length of the outer body 3 in the lateral direction Y. As shown in FIG. 2, the ventral portion A and the backside portion C respectively have a waist region D disposed on the waist of the wearer and its vicinity in the wearing state of the diaper 1A. In this waist region D, the waist elastic member 34 is extended. Status configuration. The waist region D is in each of the ventral portion A and the dorsal portion C, and extends from the waist end edges AE, CE to the end edges of the absorbent body 23 (absorptive body 2) in the longitudinal direction X near the waist end edges AE, CE. The waist area (non-arranged area of the absorptive body 2) usually occupies 8 to 80% of the total length of the longitudinal X of the ventral portion A or the back portion C. The waist edge AE is the longitudinal X edge on the ventral side A side of the outer body 3, the waist edge CE is the longitudinal X edge on the back side C side of the outer body 3, and the waist opening WH is borrowed Divided by the edges AE and CE. In this way, since the waist region D waist circumference elastic member 34 is arranged in a state showing its elastic stretchability, a substantially continuous ring-shaped waist fold is formed at the opening edge portion of the waist opening portion WH over the entire circumference. In the diaper 1A, as shown in FIG. 2, the area where the exterior body 3 and the absorbent body 2 (absorbent body 23) overlap in the longitudinal direction X of each of the ventral portion A and the backside portion C, that is, In the region closer to the lower part B than the waist region D (other than the waist region D), a plurality of linear or band-shaped waist elastic members 34 are arranged in an elongated state in the transverse direction Y, and the plurality of waist elastic members 34 are longitudinally disposed. X is arranged intermittently at a certain interval. A waist elastic member 34 disposed in a region other than the waist region D crosses the absorbent body 2. Furthermore, in the arrangement area of the absorbent body 2 in the exterior body 3 (the area overlapping with the absorbent body 2 in a plan view), the waist elastic member 34 is cut off and the like to hinder the stretchability, instead of expressing elastic stretch. Sexual state configuration. Each of the elastic members 33 and 34 described above is clamped and fixed between the outer layer sheet 31 and the inner layer sheet 32 constituting the exterior body 3 by a bonding method such as an adhesive. As the elastic members 33 and 34, stretchable materials such as natural rubber, polyurethane-based resin, foamed urethane-based resin, and hot-melt stretchable member are preferably formed into a linear shape (rubber Line) or band (rubber band). As shown in FIG. 1 to FIG. 4, in the ventral portion A and the dorsal portion C, the outer layer sheet 31 has a longitudinal end edge 32E of the inner layer sheet 32 extending outward from the longitudinal X side and faces the inner layer sheet 32. The skin facing surface 32a folds back at the turning portion 310. That is, the outer layer sheet 31 has a portion having the same shape and the same size as the inner layer sheet 32 that constitutes the main body portion forming the outer shape of the diaper 1A, and further includes a self-layer sheet when the two sheets 31 and 32 are laminated. The two end edges 32E, 32E of the longitudinal direction X of the material 32 respectively extend outward, and the extended portion is a folded-back portion 310. Furthermore, in FIG. 4, the folded-back portion 310 on the ventral portion A side and the folded-back portion 310 on the back-side portion C side are also configured similarly to the ventral portion A-side. Unless otherwise specified, the ventral portion is appropriately applied. Description of the turn-back section 310 on the A side. The folded-back portion 310 of the sheet 31 disposed outside the waist region D of each of the ventral portion A and the back portion C is a "belt-like skin closest to the sheet" located in the waist region D closest to the skin of the wearer, The skin-facing side of the exterior body 3 (the laminated body of the outer sheet 31 and the inner sheet 32), which is the main body portion forming the outer shape of the ventral portion A and the back portion C, is more specifically a waist area The skin facing surface 32a of the inner layer sheet 32 in D is arranged so as to extend laterally Y. As shown in FIG. 2, the front end 310E of the fold-back portion 310, that is, the end edge 310E of the longitudinal X in the fold-back portion 310 (the end edge 310E located on the B side of the lower part of the crotch) is located closer to the longitudinal X than the absorbent body 2 (absorber 23). The outer side, that is, the folded-back portion 310 does not overlap the absorbent body 2 (absorbent body 23). Further, in the diaper 1A, as shown in FIGS. 1 to 3, the skin-facing surfaces of the both ends of the longitudinal X of the absorbent body 2 are fixed to the body end portion of the body with a separate body from the exterior body 3. 5 and covered. The main body end fixing sheet 5 has a rectangular shape with a long lateral Y in a plan view, and is close to the portion of the waist region D of each of the ventral side A and the back side C and the area other than the waist region D. Part of the portion is continuous over the entire length of the transverse Y. The body end fixing sheet 5 is also the “skin closest sheet” located closest to the skin of the wearer, similar to the fold-back part 310, and is used to form the main body part outside the ventral part A and the back part C. The skin-facing surface 32a of the inner-layer sheet 32 in the waist region D, and more specifically, the skin-facing surface 32a of the absorptive main body 2 are arranged so as to overlap with the longitudinal X ends and extend laterally Y. In the diaper 1A, substantially the entire area of the non-skin-facing surface of the main body fixing sheet 5 is bonded to the non-skin-facing surface with a bonding agent 35 such as a hot-melt type adhesive. Therefore, The end region of the body end fixing sheet 5 including the end edge of the longitudinal X located on the B side of the lower part is fixed to the face of the body end fixing sheet 5 facing the non-skin, and does not face from the face Bulge. By using the body end fixing sheet 5, effects such as preventing leakage of urine, such as urine, from the longitudinal end portion of the absorbent body 2 and preventing the exposure of the longitudinal end portion of the absorbent body 2 are exhibited. The length of the longitudinal direction X of the body end fixing sheet 5 and the width thereof are not particularly limited, but are usually about 20 to 60 mm. As the main body end fixing sheet 5, various non-woven fabrics that can be used as the outer layer sheet 31 and the inner layer sheet 32, and a film-like sheet made of a resin that can be used as a material of the non-woven fabric can be used. As one of the main features of the diaper 1A, the following aspects can be cited: as shown in FIG. 4, the non-skin facing surface 310 b of the folded-back portion 310 (the skin is closest to the sheet) of the sheet 31 outside the ventral portion A has The non-skin facing surface 310b facing surface (that is, the skin facing surface 32a of the inner sheet 32) has a joint portion 311 and a non-joint portion 312, and has a colored portion 40 and a non-joined portion different from the ground color of the folded-back portion 310. A colored portion 41, the non-joint portion 312 is located in an end region of the folded-back portion 310 including the end edge 310E of the longitudinal X (the skin is closest to the sheet and the end edge of the longitudinal X on the lower side B side of the sheet), and includes non-coloring部 41。 41. In the form shown in FIG. 4, the entire area in plan view of the joint portion 311 is the colored portion 40, and the entire area in plan view of the non-joint portion 312 is the non-colored portion 41. The joint portion 311 is formed by joining the non-skin facing surface 310 b of the folded-back portion 310 and the skin facing surface 32 a of the inner sheet 32 to each other via the adhesive 35. The folded-back portion 310 (the skin closest to the sheet) of the outer layer sheet 31 of the back side portion C is also configured in the same manner as the ventral side portion A shown in FIG. 4. In this way, the folded-back portion 310 in the outer sheet 31 is located in the waist region D of each of the ventral portion A and the dorsal portion C and is located closest to the wearer's skin and extends along the waist end edges AE, CE in the lateral Y direction. In the configuration of the strip-shaped skin closest to the sheet, the skin-opposing surface 310a of the fold-back portion 310 is always in contact with the abdomen or back of the wearer when the diaper 1A is worn, and for example, in the wearing operation of the diaper 1A, The part where the finger touches relatively more, and the end region (the end edge 310E and its vicinity) of the lower part B side of the folded-back part 310 which has relatively more chance to contact the skin is set to be incompatible The non-joined portion 312 joined by other members becomes a free end region freely contacting the skin-facing surface 32a of the inner layer sheet 32 facing the non-joined portion 312, so that the touch of the non-joined portion 312 is provided. The softness makes the skin D feel good about the waist area D. In addition, the folded-back portion 310 has a colored portion 40 and a non-colored portion 41 arranged in the vertical direction X. The colored portion 40 is colored with a different color from the original color of the folded-back portion 310. The non-colored portion 41 is retained without being colored. The background color makes the presence of the fold-back portion 310 more obvious than the peripheral portion. Therefore, the fold-back portion 310 can be used as a positioning mark for wearing the diaper 1A at the correct wearing position, thereby enabling easy positioning during wearing. From the viewpoint of more surely exerting the positioning function of such an absorbent article brought about by the folded-back portion 310 (the skin is closest to the sheet), the non-colored portion 41 is preferably along the longitudinal direction X of the folded-back portion 310. The end region covers the lengthwise direction of the folded-back portion 310, that is, the entire length of the lateral Y, that is, there is a continuous existence from one side seal portion S to the other side seal portion S. In addition, if the non-joint portion 312 of the non-skin-facing surface 310b of the turn-back portion 310 located at the end region including the end edge 310E is colored with printing ink or the like, the non-joint portion 310 is caused by the wearer's physical activity and the like. When the joint portion 312 is rolled up, there is a concern that the non-joint portion 312 to which the printing ink is given comes into contact with the wearer's skin, resulting in a problem that the printing ink is transferred to the skin. However, in the diaper 1A, the non-joint portion 312 Since the entire system is not provided with the non-colored portion 41 of the printing ink, this worry is eliminated. From the viewpoint of realizing such an effect brought by the skin in the waist region D which is closest to the sheet material, that is, the folded-back portion 310 of the outer sheet 31, especially the viewpoint of improving the texture of the waist region D and easing the positioning operation at the time of wearing In other words, it is preferable that, when viewed along the longitudinal direction X, the skin in the waist region D is closest to the non-joint portion 312 of the folded-back portion 310 of the outer sheet 31, that is, the longitudinal direction of the folded-back portion 310 including the end edge 310E. More than half of the regions include the non-colored portions 41. That is, it is preferable that the area extending from the edge 310E on the B side of the lower portion B of the folded-back portion 310 to half or more of the total length in the longitudinal direction X of the folded-back portion 310 is the non-joint portion 312 and includes the non-colored portion 41. The ratio of the length of the longitudinal X of the non-joint portion 312 which occupies the full length of the longitudinal X of the folded-back portion 310 (the skin is closest to the sheet) is preferably 10% or more, further preferably 20% or more, and more preferably 50% Hereinafter, it is more preferably 40% or less. The ratio of the length of the longitudinal direction X of the non-colored portion 41 occupying the entire length of the longitudinal direction X of the folded-back portion 310 (the skin is closest to the sheet) is preferably 1. 5% or more, more preferably 10% or more, more preferably 60% or less, and still more preferably 50% or less. The proportion of the length of the longitudinal X of the non-colored portion 41 occupying the entire length of the longitudinal X of the non-joint portion 312 is preferably 20% or more, further preferably 30% or more, more preferably 100% or less, and even more preferably 90% or less. In the form shown in FIG. 4, since the entire area of the non-joint portion 312 in plan view has the non-colored portion 41, the ratio is 100%. When the ratio of the length of the longitudinal X of the non-colored portion 41 which occupies the entire length of the longitudinal X of the non-bonded portion 312 is less than 100%, that is, the non-bonded portion 312 includes both the colored portion 40 and the non-colored portion 41 In this case, it is preferable that the non-colored portion 41 is disposed on the side of the edge 310E of the longitudinal direction X of the folded-back portion 310 (the skin is closest to the sheet). The proportion of the total length of the longitudinal X of the folded-back portion 310 (the skin closest to the sheet) of the longitudinal X of the ventral portion A is preferably 8% or more, further preferably 10% or more, and more preferably 35% Hereinafter, it is more preferably 30% or less. The fold-back portion 310 of the back side portion C may be set in the same manner as the abdominal side portion A. The length of the longitudinal X of the non-colored portion 41 of the folded-back portion 310 (the skin is closest to the sheet), that is, the width is preferably 2 mm or more, further preferably 5 mm or more, and more preferably 20 mm or less, further preferably 15 mm or less. In the diaper 1A, as shown in FIGS. 1 to 4, the skin-facing surface 31 a of the outer sheet 31 and the non-skin-facing surface 32 b of the inner sheet 32 have colored portions 40 different from the ground color, respectively. More specifically, the outer layer sheet 31 has a colored portion 40 over the entire area facing the inner layer sheet 32 in the portion other than the non-joint portion 312, and the inner layer sheet 32 is formed on the non-joining portion 312. The skin facing surface, that is, the entire area facing the outer sheet 31 has a colored portion 40, and neither of the two sheets 31, 32 exposes the colored portion 40. That is, in the diaper 1A, the entire body forming the outer shape of the diaper 1A, that is, the entirety of the laminated body of the outer layer sheet 31 and the inner layer sheet 32 is colored to a color different from the ground color, and the colored portion exists in The interface between the two sheets 31 and 32 constituting the laminated body is not exposed on the outer surface. The colored portion 40 of each of the skin facing surface 31 a of the outer sheet 31 and the non-skin facing surface 32 b of the inner sheet 32 is the same color as the colored portion 40 of the folded-back portion 310. Moreover, in the diaper 1A, the main body end fixing sheet 5 is not colored and maintains the ground color, but the entire area of the non-skin-facing surface may be colored with printing ink or the like. In the diaper 1A having this structure, as shown in FIG. 1 and FIG. 2, the main body part that forms the outer shape of the diaper 1A, that is, the exterior body 3 as a whole has a color different from the ground color, and the main body part is made of colored Since a plurality of (two) sheets 31 and 32 are laminated bodies, when the diaper 1A is viewed from the outside, it is observed that the color of the implemented coloring is relatively deep and the design is high. In addition, when visually inspecting the inner surface of the diaper 1A, that is, the skin-facing side, the background portion of the diaper 1A, that is, the colored portion 40 of the exterior body 3 is used as the background, and the end portion of the fold-back portion 310 is maintained as the ground color. Since the non-colored portion 41 (non-bonding portion 312) extends in the lateral direction Y in the waist region D, it is conspicuous by the contrast with the colored portion 40. Therefore, the non-colored portion 41 can be used as a mark when positioning the diaper 1A in a correct wearing position. In addition, the non-skin facing surface 31b of the outer layer sheet 31 outside the diaper 1A is formed, and the skin facing surface 310a and the inner layer of the folded-back portion 310 forming the inner surface of the diaper 1A that may come in contact with the wearer's skin The skin-opposing surface 32a of the sheet 32 does not have the colored portion 40, so it effectively prevents the printing ink constituting the colored portion 40 from being transferred to the wearer's skin or clothes to stain them, which is called transfer dyeing. . The non-colored portion 41 in the folded-back portion 310 of the outer layer sheet 31 exhibits a background color originally possessed by the outer layer sheet 31, and the background color is not particularly limited, and is usually white. The ground color of not only the outer layer sheet 31 but also the other constituent members of the diaper 1A is usually white. In addition, the color of the colored portion 40 may be any color that can be distinguished visually from the background color presented by the non-colored portion 41, and any color may be selected. For example, when the ground color of each component of the diaper 1A is white, as the color of the colored portion 40, red, blue, yellow, or the like can be selected. The colored portion 40 can be formed by printing the constituent members of the diaper 1A such as the outer layer sheet 31 and the inner layer sheet 32 by a known method. In addition, in the diaper 1A, when viewed in the longitudinal direction X, the length of the non-colored portion 41 (the length of the longitudinal direction X) of the end region of the folded-back portion 310 of the outer sheet 31 is in the ventral portion A and the back portion C. The length of the non-colored portion 41 is the same as that of the abdomen portion A and the back portion C. "The length of the non-colored portion 41 is different from that of the ventral portion A and the dorsal portion C", not only that both the ventral portion A and the dorsal portion C have the non-colored portion 41, but also includes only the ventral portion. One of the side portion A and the back side portion C has a non-colored portion 41, and the other does not have a non-colored portion. With this configuration, it is easy to further distinguish the ventral portion A from the backside portion C, and therefore it is possible to effectively prevent the diaper 1A from being mistakenly worn and worn. Regarding the length of the longitudinal direction X of the non-colored portion 41, either the ventral portion A may be longer than the dorsal portion C, or the back portion C may be longer than the ventral portion A. Hereinafter, another embodiment of the present invention will be described with reference to FIGS. 5 to 8. Regarding other embodiments described below, components different from the above-mentioned diaper 1A will be mainly described, and the same components are denoted by the same reference numerals, and description thereof will be omitted. As for the components not specifically described, the description about the diaper 1A is appropriately applied. In the diaper 1B shown in FIG. 5, the longitudinal end edge 32E of the inner layer sheet 32 is located closer to the lower part B than the end edge 310E of the folded back portion 310 of the outer layer sheet 31, and the folded back portion 310 is not connected to the inner layer sheet. 32 overlaps, and is bonded to the relatively outward-facing sheet 31 via the adhesive 35. In the diaper 1B, instead of the inner layer sheet 32 not overlapping the folded-back portion 310, the body end fixing sheet 5 and the folded-back portion 310 are overlapped. That is, as shown in FIG. 5, the non-skin facing surface 310 b of the end region including the end edge 310E of the longitudinal X and the body end fixing sheet 5 includes the longitudinal X of the waist end edge AE side. The skin facing surface in the end region of the end edge is opposite to each other, and at the opposite portion, the folded-back portion 310 overlaps with the body end fixing sheet 5. Further, the non-skin facing surface 310b of the end region including the end edge 310E of the folded-back portion 310 is not joined to the end region of the opposite body end fixing sheet 5 including the end edge of the longitudinal X, and the whole is not The joint portion 312 is also the non-colored portion 41. The body end fixing sheet 5 is an entire area of the non-skin-facing surface, which is joined to the non-skin-facing surface by an adhesive 35 (in FIG. 5, the skin-facing surface of the outer sheet 31 is facing the skin). The skin-facing surface 32a of the surface 31a and the inner layer sheet 32). In addition, the diaper 1B shown in FIG. 5 is a ventral part, and a back part is comprised similarly to a ventral part. The same effect as that of the diaper 1A is exhibited also by the diaper 1B. However, in the diaper 1B, the colored sheet overlapping the non-colored portion 41 (non-joined portion 312) of the folded-back portion 310 in plan view is only one outer layer sheet 31. In contrast, the colored sheet in the diaper 1A The outer layer sheet 31 and the inner layer sheet 32 are two in total. Therefore, regarding the color of the background which becomes the non-colored portion 41 when viewed visually, the diaper 1A is deeper than the diaper 1B. Therefore, in the diaper 1A, Due to the contrast with its deep background color, the visibility of the non-colored portion 41 is further excellent. In the diaper 1C shown in FIG. 6, the folded-back portion 310 of the outer sheet 31 is the entire area of the non-skin-facing surface 310 b, which is bonded to the non-skin-facing surface 310 b by the adhesive 35. The skin-facing surface 32 a of the layer sheet 32 is a colored portion 40 different from the ground color of the folded-back portion 310 and does not include the non-colored portion 41. On the contrary, in the diaper 1C, the body-side fixing sheet 5 which is the "skin closest sheet" closest to the wearer's skin is the same as the folded-back portion 310 of the outer sheet 31, and is partially bonded to the side facing it, and By having a non-colored portion, the same effect as that of the folded-back portion 310 in the diaper 1A can be exhibited. That is, in the diaper 1C, as shown in FIG. 6, the non-skin facing surface 5 b of the body end fixing sheet 5 has a surface facing the non-skin facing surface 5 b (the inner layer sheet 32 in FIG. 6). The skin-facing surface 32a) has a joint portion 51 and a non-joint portion 52, and has a colored portion 40 and a non-colored portion 41 that are different from the ground color of the body end fixing sheet 5. The non-joint portion 52 is fixed at the end of the body. The sheet 5 includes an end region including an end edge 5E in the longitudinal direction X, and includes a non-colored portion 41. In the form shown in FIG. 6, the entire area of the non-joint portion 52 in plan view has the non-colored portion 41. 6 shows the ventral portion of the diaper 1C, and the back portion is also configured in the same manner as the ventral portion. The diaper 1C also exhibits the same effects as the diaper 1A. The diaper 1D shown in FIG. 7 and FIG. 8 is a so-called unfoldable disposable diaper, and includes a front sheet 11 that forms a liquid-permeable surface on the inner surface of the diaper 1D, and a non-skin facing that forms the diaper 1C. The surface is the liquid-impermeable or water-repellent back sheet 12 on the outer surface, and the absorber 13 arranged between the two sheets 11, 12 in the longitudinal direction X having a ventral portion A, a lower portion B, and a dorsal portion C A pair of hook-and-loop fasteners 14 and 14 are provided on the side edges of the back side portion C along the longitudinal direction X, and on the non-skin facing surface of the ventral portion A, the hook-and-loop fastener 14 is used for fixing.

There are a pair of three-dimensional folds. In addition, the elastic members 18 are arranged in a stretched state along the longitudinal direction X on the left and right leg portions arranged around the wearer's legs, whereby a pair of leg folds are formed on the leg portions when worn. As shown in FIG. 8, the back sheet 12 is formed of a laminated body that is relatively far from the outer sheet 120 of the absorbent body 4 and the inner sheet 121 that is relatively close to the absorbent body 4. The outer sheet 120 is located farthest from the wearer's skin and forms the outer surface of the diaper 1D. The length of the inner layer sheet 121 and the absorbent body 4 in the transverse direction Y are substantially the same. In contrast, the outer layer sheet 120 has a longer length in the transverse direction Y than the inner layer sheet 121 and covers the non-skin of the inner layer sheet 121 The entire area of the facing surface further extends from the side edges of the inner layer sheet 121 along the longitudinal direction X to the outer side of the transverse direction Y, and forms a side wing portion with the side sheet material 16. As the outer layer sheet 120, various non-woven fabrics can be used from the viewpoint of obtaining a good texture, and as the inner layer sheet 121, a resin film or a layer of a resin film and a non-woven fabric can be used from the viewpoint of ensuring leakproofness. Laminating and so on. More specifically than the back sheet 12, the outer sheet 120 is a main body formed outside the diaper 1D, and is naturally a main body formed outside of each of the abdominal portion A, the lower crotch portion B, and the back portion C. That is, the outer layer sheet 120 has the largest area among all the constituent members of the diaper 1D, and forms an outer shape of the diaper 1D in an expanded and stretched state as shown in FIG. 7. That is, the outline of each of the ventral portion A, the lower iliac crest B, and the dorsal portion C. In the diaper 1D, as shown in FIG. 7 and FIG. 8, the non-skin facing outer sheet 120 forming only the back sheet 12 has a colored portion 40, which is located closer to the wearer's skin than the back sheet 12 and is covered.
