When the tape tab 20 has such an arrangement, when the diaper 10 is rolled up and discarded, for example, when the tape tab 20 is wound around and the distal portion 22 is secured to the outer surface of the crotch region 15 and transported, the waist It is possible to maintain a well-rounded shape so that the opening is opened and the excrement is not exposed. However, as long as the effect of the present invention is exhibited, the tape tab 20 may be disposed in a portion other than the central portion in the longitudinal direction Y at both side edge portions 18 of the rear waist region 14, or on one side edge portion 18. May be attached, or may be attached to at least one side edge of the front waist region 13 instead of the side edge 18 of the rear waist region 14. Furthermore, as long as excrement can be prevented from leaking from the waist opening and the leg opening at the time of disposal, the front waist region 13 / the rear waist region 14 may be disposed in the vicinity of the waist opening.

  Referring to FIG. 3, the front and rear waist panels 16 and 17 have front and rear waist sheets 25 and 26 having substantially horizontally long rectangles that form the front and rear waist regions 13 and 14, respectively. The front and rear waist sheets 25 and 26 have inner surface sheets 27 and 29 positioned on the skin contact surface side and outer surface sheets 28 and 30 positioned on the non-skin contact surface side, respectively. Between the inner and outer surface sheets 28 and 29 of the front waist sheet 25, a plurality of string-shaped or strand-shaped front waist elastic bodies 31 extending in the lateral direction are attached so as to be contracted in an extended state. Further, a plurality of string-shaped or strand-shaped rear waist elastic bodies 32 extending in the lateral direction are attached between the inner and outer surface sheets 29, 30 of the rear waist sheet 26 so as to be contracted in an extended state. The front and rear waist regions 13 and 14 have front and rear waist elastic regions that can be expanded and contracted in the lateral direction X by the contraction force of the front and rear waist elastic bodies 31 and 32, respectively.

The front and rear waist sheets 25 and 26 have a mass of about 10 to 40 g / m ² and a fiber density of about 0.03 to 0.1 g / cm ³ , for example, a spunbond nonwoven fabric, SMS (spunbond meltblown) -Spunbond) Nonwoven fabric, air-through nonwoven fabric, plastic sheet, or laminate sheet thereof can be used. As the front and rear waist elastic bodies 31 and 32, for example, a string-like or strand-like elastic material having a fineness of about 300 to 500 dtex and an expansion ratio of 1.5 to 3.5 times can be used. The thickness and expansion ratio of the front and rear waist elastic bodies 31 and 32 can be changed as appropriate.

  The liquid absorption structure 12 has a vertically long rectangular shape, and includes a front end portion 12A, a rear end portion 12B, and a central portion 12C located between the front and rear end portions 12A and 12B. The liquid-absorbing structure 12 is located on the skin contact surface side, and is a body-side liner 40 made of a fiber nonwoven fabric having liquid permeability, a liquid-absorbing absorber 41 having curved side edges, and an absorber 41. A liquid-impervious leak-proof sheet 42 that covers the entire bottom surface of the liquid-absorbing structure, and a hydrophobic covering sheet 43 that forms the entire non-skin-contacting surface of the liquid-absorbing structure 12. The absorbent body 41 includes a core material formed from a mixture of fluff pulp and superabsorbent polymer particles, and a liquid-absorbing and diffusible core wrap sheet such as tissue paper that encapsulates the entire core material.

  The covering sheet 43 has both side portions 44 located on the outer side in the lateral direction X from both side edges of the leak-proof sheet 42. Both side portions 44 are bent inward along both side edges of the leak-proof sheet 42 and are fixed to the leak-proof sheet 42 and the body side liner 40. A sleeve-like free edge 43a that is not fixed to the body side liner 40 is located on the outer edges of the side parts 44, and a plurality of strings or strands extending in the longitudinal direction Y inside the free edge 43a The cuff elastic body 45 is disposed in a stretched state so as to be contractible. When the cuff elastic body 45 contracts, the free edge 43a is separated from the body-side liner 40 toward the wearer's body, and fits the wearer's thigh to prevent excrement from leaking. A plurality of string-like or strand-like leg elastic bodies 46 are disposed between both side portions 44 of the covering sheet 43 and the leak-proof sheet 42.

  FIG. 5 is a cross-sectional view taken along the line VV in FIG. 4, and FIG. 6 is a state in which the front and rear waist regions 13 and 14 are extended in the vertical direction Y and the horizontal direction X to the extent that no wrinkles are formed on the outer surface. It is sectional drawing similar to FIG. In addition, although FIGS. 4-6 and the following description have shown about the one side part of the diaper 10, it has the same structure also in the other side part.

  4 to 6, the tape tab 20 has a thickness direction Z and is fixed to the outer surface of the side edge 18 of the rear waist region 14 via joints (first and third joints 71 and 73). And a distal portion 22 indirectly or directly opposite the proximal portion 21 in the thickness direction Z. The proximal portion 21 includes a first proximal portion 21A fixed to the side seam region 23, and a second proximal portion 21B that is located apart from the first proximal portion 21A in the lateral direction X of the first proximal portion 21A. Have. In the present specification, the “proximal portion” means one or a plurality of portions fixed to the outer surface of the rear waist region 14 of the tape tab 20, which are formed from the same or different tape base materials. Means things.

  The tape tab 20 further includes an intermediate portion 61 that is located between the proximal portion 21 and the distal portion 22 and faces them in the thickness direction Z. The tape tab 20 according to the present embodiment is formed of a plurality of tape base materials (tape pieces) folded into a Z-shaped cross section, and specifically, a first tape base that forms the second proximal portion 21B. It has the material 51 and the 2nd tape base material 52 which forms 21 A of 1st proximal parts, the intermediate part 61, and the distal part 22. FIG.

  As for the 1st tape base material 51, one edge part (1st bending part 56a) is bend | folded outside the thickness direction Z along the 1st bending line 56, and this bending part 56a and 2nd tape The base material 52 is joined by the second joint portion 72. The 2nd tape base material 52 is being fixed to the side edge part 18 and the 1st tape base material 51 in the state folded in two along the 2nd bending line 57 located in the approximate center part of the length direction. Yes. The first proximal portion 21A is formed by fixing one end portion of the second tape base material 52 to the side edge portion 18 via the third joint portion 73, and the intermediate portion 61 is the first proximal portion 21A. The distal portion 22 is formed from a portion extending outward in the lateral direction X from the second folding line 57 outside the intermediate portion 61 in the thickness direction Z. The second bent portion 57a) is formed. The 2nd tape base material 52 has the outer surface 20a and the inner surface 52b located in the other side. The outer surface 20a of the second tape substrate 52 forms the outer surface of the tape tab 20 in the bent state, and the inner surface 52a of the second tape substrate 52 forms the inner surface of the distal portion 22.

  The proximal portion 21, the intermediate portion 61, and the distal portion 22 are positioned between the first and second bent lines 56, 57 in a state where they are stacked on each other, and have a plurality of dot-like temporary fixing portions 65, 66 is temporarily fixed. The distal portion 22 further includes a gripping portion 63 extending outward in the lateral direction X from the first temporary fixing portion 65 located at the first bent portion 56a. A fastening area 68 formed of a hook sheet 68a and a hook element 68b of a mechanical fastener is disposed on the inner surface of the distal portion 62 between the temporary fixing portions 65 and 66. The fastening area 68 may be a pressure sensitive adhesive or the like when the outer surface of the diaper 10 is formed of a plastic film.

The tape base material forming the tape tab 20 includes a fiber nonwoven fabric, at least part of which includes, for example, heat-sealable synthetic fibers such as polyethylene, polypropylene, and polystyrene, and has a mass of, for example, about 30 to 100 g. / M ² , preferably a spunbond fiber nonwoven fabric having a mass of about 40 g / m ² or more can be used.

For the first to third joints 71, 72, 73, various known joining means such as adhesion or welding such as sonic seal or heat seal can be used. For example, when using the adhesion means, the mass is about 5 to 5. A 20 g / m ² hot melt adhesive can be used. The temporary fixing portions 65 and 66 can be formed by performing a known pressure treatment or pressure heat treatment, and can be formed by, for example, an embossing treatment or a sonic treatment. When the pressure heating treatment is performed, when the tape tab 20 itself has a thermoplastic synthetic fiber, it can be temporarily fixed more stably by heat fusion. Referring to FIG. 4, the temporary fixing portions 65 and 66 have a plurality of dot shapes arranged so as to be separated from each other in the vertical direction Y and the horizontal direction X. In this way, the tape tab 20 is more flexible by being locally disposed on the outer surface of the tape tab 20 in a state where the temporary fixing portions 65 and 66 are laminated, as compared with the case where the tape tab 20 is disposed on the entire outer surface. There is no risk of damage.

  Referring to FIG. 4 and FIGS. 7A and 7B described later, a first display having a plurality of printed first display elements 34a on one surface forming the outer surface 20a of the second tape base 52. An area 34 and a second display area 35 having a plurality of printed second display elements 35a are located. The first display area 34 is located on the outer surface 20 a of the gripping portion 63, and the second display area 35 is located on the outer surface 20 a of the remaining portion 64 of the distal portion 22 excluding the gripping portion 63. The first display element 34a and the second display element 35a have different displays to the extent that they can be visually distinguished. In the present embodiment, the first display element 34a is composed of a plurality of lines extending in the width direction of the tape tab 20, and the second display element 35a is composed of a plurality of dots. Reference numeral 34 denotes a striped pattern, and the second display area 35 has a polka dot pattern.

  As long as the first and second display elements 34a and 35a can be visually distinguished from each other, various known displays such as colors, characters, designs, and symbols other than white and milky white can be used. Further, in this specification, “the first display element 34a and the second display element 35a have different displays” means that the displays are different from each other to such an extent that they can be visually distinguished. This includes a case where the display is a different pattern, a design of the same shape and a different colored color, or one of which is a design while the other is made up of characters.

  Referring to FIG. 6, in order to easily grip the gripping portion 63, it is preferable that the gripping portion 63 is relatively large. Specifically, the dimension L <b> 2 in the lateral direction X is about 10 mm or more. It is preferably about 20% or more of the dimension L1 in the lateral direction X of the distal portion 22. Thus, since the length dimension of the gripping part 63 is relatively large, it becomes easy to grip the gripping part 63 extending outward in the lateral direction X, and the decorative element 82 is provided on the diaper 10 in the rear view. It can be easily visually recognized. Further, the separation dimension R in the lateral direction X between the side seam region 23 and the temporary fixing portion 65 is preferably about 5 mm or more. In this way, by forming the separation dimension R to be relatively large, the vicinity of the proximal end of the gripping portion 63 is raised toward the outside in the lateral direction X by the separation portion 77, and the gripping portion 63 is viewed from the front. And it becomes an aspect which protrudes to the outer side of the horizontal direction X in the rear view.

The tape tab 20 attached to the side edge portion 18 of the rear waist region 14 in the folded state as described above is temporarily attached by the operator holding the holding portion 63 and pulling it in the pulling direction P. The temporary fixing by 65 and 66 is released. The tape tab 20 according to the present embodiment has a so-called Y-shaped configuration in which the proximal portion 21 fixed to the rear waist region 14 includes a first proximal portion 21A and a second proximal portion 21B that are separated from each other in the lateral direction X. Since it is a tape tab, when it pulls in the pulling direction P, the peeling force which acts on 21 A of 1st proximal parts can be reduced. In addition, since the tape tab 20 has a joining mode, the peeling force acting on the first proximal portion 21 </ b> A even when the gripping portion 63 is pulled and deployed not in the pulling direction P but inward in the lateral direction X. Can be reduced. Moreover, as long as the tape tab 20 has required peel strength, it may be formed from only one tape base material, or may be formed from two or more tape base materials.

  Referring to FIG. 5, when the diaper 10 is worn and not worn, the entire rear waist region 14 is contracted in the lateral direction X by the rear waist elastic body 32 to form a plurality of gathers 80. In the rear waist region 14, at least one rear waist elastic body 32 is located in the arrangement region of the proximal portion 21 of the tape tab 20, and the proximal portion 21 is surrounded by the contraction force of the elastic body 32. It has an undulating shape that continues in the direction. In the present embodiment, in the state where the tape tab 20 is not attached to the outer surface of the diaper 10, the number, fineness, pitch, and the like of the front and rear waist elastic bodies 31, 32 are set so that the contraction force of the front and rear waist elastic regions is substantially equal. Is set as appropriate.

  Normally, when the contraction forces are substantially equal in the front and rear waist elastic regions, the side seam region 23 is outward in the lateral direction X without tilting forward or rearward, as indicated by phantom lines in FIG. It extends so as to protrude to the side. However, in the present embodiment, the proximal portion 21 of the tape tab 20 is positioned at the side edge 18 of the rear waist region 14, thereby reducing the contraction force of the elastic region where the proximal portion 21 exists in the rear waist elastic region. Thus, the contraction force is lower than that of the elastic region of the front waist region 13 opposed in the front-rear direction. Therefore, in the side seam region 23, the contraction amount of the front portion 23a composed of the side edge portion of the front waist region 13 located on the inner side of the rear portion 23b composed of the side edge portion 18 of the rear waist region 14 located on the outer side. The size of the front portion 23a is larger than that of the rear portion 23b, and the side seam area 23 is curved inwardly in the lateral direction X with the rear portion 23b outside. Become.

  As described above, since the side seam region 23 has a curved shape, the side seam region 23 and portions adjacent to the outside and the inside in the lateral direction X also have a curved shape, and the side seam. 21 A of 1st proximal parts fixed to the area | region 23 and the part 81 adjacent to the outer side of the horizontal direction X also become a curved shape. The gripping portion 63 located on the side seam region 23 side with respect to the temporary fixing portion 65 is not joined to the intermediate portion 61 opposed to the holding portion 63, so that it is separated from the intermediate portion 61 and extends outward in the thickness direction Z.

  Referring to FIGS. 1 and 2, since the front and rear waist regions 13 and 14 are contracted, that is, in the wearing state of the diaper 10, the tape tab 20 has such an aspect, so that the gripping portion 63 has both side edges of the diaper 10. It will be in the state which protruded to the outer side of the horizontal direction X from 10b. Therefore, when the tape tab 20 is unfolded at the time of disposal or size adjustment of the diaper 10, there is no possibility that the gripping portion 63 overlaps with the curved intermediate portion 61 and is difficult to grip, and the thickness is separated from the intermediate portion 61. Since the gripping part 63 extending in the vertical direction Z can be easily gripped, the operability is excellent.

  Referring to FIG. 5 again, the rear waist region 14 has an undulating shape by a plurality of gathers 80, and the second proximal portion 21B fixed thereto also contracts in the lateral direction X to have an undulating shape. The intermediate portion 61 and the distal portion 22 facing the proximal portion 21B are not fixed to the second proximal portion 21B, and a fastening region 68 is formed on the inner surface of the distal portion 22 to locally It is not undulating due to its high rigidity. The separating portion 77 where the first proximal portion 21A and the second proximal portion 21B are separated from each other in the lateral direction X has a shape that protrudes outward in the thickness direction Z because the side edge 18 that opposes the contracting portion 77 contracts. Have Since the temporary fixing portion 65 is located at the first bent portion 56a, the separation portion 77 is opposed to the vicinity of the proximal end of the gripping portion 63. Therefore, the vicinity of the proximal end of the gripping portion 63 is the separation portion. Positioned on 77, the gripping part 63 exhibits a mode of extending more stably outward in the lateral direction X. Further, since the gripping portion 63 is located on the convexly spaced portion 77, the temporary fixing of the temporary fixing portions 66 and 65 can be released by pulling the gripping portion 63 so as to slide in the pulling direction P. . As described above, since the temporary fixing can be released mainly by a shearing force, the tape tab 20 can be developed with a smaller pulling force.

  7A is a plan view of the tape tab 20 in a folded state, FIG. 7B is a plan view of the tape tab 20 in an unfolded state, and FIG. 8A is a view when the diaper 10 is discarded. The figure which shows a mode that the tape tab 20 is operated, FIG.8 (b) is a figure which shows a mode that the tape tab 20 was fixed to the folded diaper 10. FIG. Note that the diaper 10 shown in FIGS. 8A and 8B extends in the lateral direction X after both sides are bent inward in the lateral direction X so that the front waist region 13 or the rear waist region 14 is inside. The crotch region 15 is folded along the folding line toward the waist region, and is compact, and is known as a bending mode employed when the diaper 10 is discarded.

  Referring to FIGS. 7A and 7B, as described above, the outer surface of the gripping portion 63 is a striped pattern composed of a plurality of line-shaped first display elements 34 a extending in the width direction of the tape tab 20. The first display area 34 having a stagnation position is located, and the outer surface of the remaining portion 64 excluding the gripping portion 63 of the distal portion 22 has a polka dot pattern composed of a plurality of dot-like second display elements 35a. A second display area 35 is located. Usually, the tape tab 20 has the original white color of the non-woven fabric or plastic tape base material, like the outer surface of the diaper 10, and it is difficult to visually recognize the outer contour of the diaper 10 when the tape tab 20 is used. In addition, it may be difficult to grip the gripping portion 63. In the diaper 10 according to the present embodiment, the outer surface 20a of the tape tab 20 is provided with the first and second display areas 34 and 35 that are colored and / or designed, thereby facilitating the outline of the tape tab 20. Can be visually recognized, and the gripping portion 63 can be gripped.

  Since the first display area 34 arranged on the outer surface of the gripping portion 63 and the second display area 35 located on the outer surface of the remaining portion 64 have different display elements in the distal portion 22 of the tape tab 20, A person can easily recognize the relative size and range of the gripping portion 63 with respect to the entire tape tab 20. Further, in this way, the display element of the first display area 34 arranged on the outer surface of the gripping portion 63 for gripping when the tape tab 20 is unfolded, and the second display disposed on the outer surface of the remaining portion 64. Since the display elements of the area 35 are different from each other, the first and second display areas 34 and 35 can each serve as a function display unit representing a function of a portion where the first and second display areas 34 and 35 are arranged.

  Referring to FIGS. 8A and 8B, when the diaper 10 is to be discarded, the wear assistant folds the diaper 10 and then holds the folded diaper 10 with one hand, and also removes the tape tab 20. The holding portion 63 is gripped and deployed while pulling in the pulling direction P so as to press the first portion 84 composed of the front and rear waist regions 13 and 14 overlapped with each other against the second portion 85 composed of the crotch region 15. Next, when the fixed area 68 of the expanded tape tab 20 is pressed against the outer surface of the diaper 10 (the outer surface of the crotch area 15) and fixed, the portion where the second display area 35 is disposed is pressed with the thumb. Thus, the fastening area 68 is fastened. Since the fastening area 68 is disposed on the inner surface 52b of the distal portion 22, it is difficult to visually recognize the existence area in the external appearance of the tape tab 20, but the second display area 35 is located in the existence area. By doing so, the fastening area 68 can be reliably pressed by a finger to be fastened.

  Thus, in order to recognize the existence area of the fastening area 68 located on the inner surface of the distal portion 22 in the external view of the tape tab 20, the second display area 35 is arranged at least in the existence area of the fastening area 68. The second display area 35 does not have to be arranged in a portion of the distal portion 22 located in the lateral direction X from the fastening area 68. However, since the second display area 35 is arranged on the entire outer surface of the remaining portion 64 excluding the gripping portion 63 of the distal portion 22, the wear assistant consciously displays the second display on the entire middle of the thumb. Since the area 35 is pressed against the outer surface of the diaper 10, the fixing area 68 and the portion adjacent thereto are pressed against each other, so that the fixing can be performed more reliably.

  Moreover, since the panel member which comprises the front-and-back waist areas 13 and 14 is the same shape, the diaper 10 is difficult to discriminate | determine the front and back of the diaper 10 in an external appearance. By arranging the first and second display areas 34 and 35 on the outer surface, the first display area 34 is located on the front side and the second display area 35 is located on the rear side. Can be determined. Therefore, even if there is no display for distinguishing the front and rear in the front and rear waist regions 13 and 14, it is possible to easily perform the wearing operation with easy front and rear discrimination before wearing.

  As described above, in the tape tab 20 according to the present embodiment, the first proximal portion 21A is fixed to the side seam region 23, whereby the grip portion 63 is opposed to the intermediate portion 61 in the thickness direction Z. And extend outward in the lateral direction X. Further, the separating portion 77 has a shape that is curved outward in the thickness direction Z, and the gripping portion 63 positioned on the separating portion 77 extends outward in the lateral direction X. Accordingly, only the gripping portion 63 protrudes outward in the lateral direction X at the distal portion 22, and the gripping becomes easier and the first display area 34 is easily visually recognized. The proximal portion 21 / the first proximal portion 21A may not be located on the side seam region 23 as long as the arrangement region moves to the front side, and the side edge portion 18 of the rear waist region 14 In addition, it may be located inside the lateral direction X with respect to the side seam region 23.

  Referring to FIG. 7A, the first temporary fixing portion 65 is located near the boundary between the first display area 34 and the second display area 35. Since the first temporary fixing portion 65 has such an arrangement mode, all the portions separated from the intermediate portion 61 become the holding portions 63, so that the entire portion can be easily held, and the first temporary fixing portion When the fastening region 68 is adjacent to the inside of the portion 65 in the lateral direction X, the fastening region 68 can be reliably pressed against the outer surface of the diaper main body 10A when performing the fastening operation.

Further, the total area of the first display elements 34 a in the first display area 34 is larger than the total area of the second display elements 35 a in the second display area 35 when the tape tab 20 is folded. On the other hand, when the tape tab 20 is unfolded, the total area of the first display elements 34 a in the first display area 34 is smaller than the total area of the second display elements 35 a in the second display area 35. Thus, since the correlation between the total area of the first display element 34a and the total area of the second display element 35a differs between the folded state and the expanded state of the tape tab 20, the tape tab 20 is used. At this time, the gripping portion 63 is more easily recognized, and the second display element 35a is more easily recognized when the tape tab 20 is unfolded and fixed to the outer surface of the diaper 10. So, for example,
By making the decorativeness (designability) of the second display element 35b higher than that of the first display element 34a, the second display area 35 appears relatively large when the tape tab 20 is fastened. Designability in appearance is improved.

  As the first and second display elements 34a and 35a, various known display elements such as coloring, characters, designs, symbols, and the like can be used as long as they can be visually distinguished from each other. In order to improve the design on the appearance of the diaper 10 in a state where the tape tab 20 is unfolded, for example, the second display element 35a is a non-continuous polka dot pattern composed of a plurality of dots, a plurality of triangles, stars, rectangles, etc. In the case of using a design of the nature, the first display element 34a of the first display area 34 is preferably a continuity design such as a line pattern. In such a case, the first display area 34 and the second display area 35 can be easily distinguished, and the boundary between the display areas 34 and 35 can be grasped.

  Referring to FIG. 7B, the distal portion 22 has a remaining portion 64 excluding the gripping portion 63, and the second display area 35 is located on the entire outer surface 20 a of the remaining portion 64. In a state where the tape tab 20 is unfolded, the second display area 35 includes a first area 64A in which the fastening area 68 is located on the inner surface 52b, a second area 64B adjacent to the first area 64A, and the proximal portion 21 side. And a third section 64C in which a first tape base 51 (folded portion 56a) separate from the second tape base 52 is disposed on the outer surface 20a.

  In the first area 64A, the white or milky white hook sheet 68a disposed on the inner surface 52b is transmitted, whereby the second display element 35a printed on the outer surface 20a, which is one surface of the second tape base 52, Compared with the second area 64B, it is visually recognized more clearly. On the other hand, in the 3rd area 64C, since the 1st tape base material 51 is arranged so that the 2nd tape base material 52 may be covered, the visibility of the 2nd display element 35a falls compared with the 2nd area 64B. . Thus, since the correlation of the visibility of the second display element 35a in each of the areas 64A, 64B, and 64C of the second display area 35 is first area 64A> second area 64B> third area 64C, The 2 display area 35 is darker in color from the proximal portion 21 side toward the gripping portion 63 side. Therefore, the shades of the colors of the areas 64A to 64C can be made different without controlling the color of the second display element 35a itself. The tape tab 20 is improved in design by the contrast due to the difference in color in the second display area 35, and the wear assistant easily grasps the area where the fastening area 68 is arranged in the entire second display area 35. be able to.

  In the present embodiment, the first display area 34 is disposed on the outer surface 20a of the gripping part 63, but the first display area 34 is disposed on the inner surface of the gripping part 63 as long as it is visible from the outside. Also good. In the contracted state of the rear waist region 14, the separation portion 77 has a shape that is curved outward in the thickness direction Z, and the gripping portion 63 positioned on the separation portion 77 extends further outward in the lateral direction X. Therefore, the inner surface of the gripping portion 63 is exposed. Therefore, even when the first display area 34 is arranged on the inner surface of the gripping portion 63, the wearer can grasp the gripping portion 63, and as long as the first display area 34 is located on the outer surface 20a. May be seen through so as to be visible from the inner surface side. Furthermore, you may arrange | position the decorative element which has a respectively different design in the outer surface 20a and the inner surface 52b of the holding part 63, respectively.

  FIG. 9 is a cross-sectional view similar to FIG. 6 in an example of the embodiment. The tape tab 20 according to the present embodiment is a state in which one tape base material is folded in two, and the proximal portion 21 fixed to the side edge portion 18 of the rear waist region 14 and the thickness direction Z A distal portion 22 opposite the proximal portion 21. The proximal portion 21 and the distal portion 22 are temporarily fixed to each other via temporary fixing portions 65 and 66, and the tape tab 20 can be developed by pulling the gripping portion 63 to release the temporary fixing. A first display area 34 having a first display element 34a (not shown) is located on the outer surface 20a of the gripping portion 63 of the tape tab 20, and a portion 64 of the distal portion 22 excluding the gripping portion 63 is located on the portion 64. A second display area 35 having a second display element 35a (not shown) having a different form from the first display element 34a is located. Thus, even if the tape tab 20 is a mode in which a single tape base material is folded in two, the first display area 34 and the second display area 35 can be distinguished from each other in the appearance of the diaper 10.

  In the present specification, “the first and second display areas 34 and 35 are visually recognized” means that the room has a certain brightness by a fluorescent lamp, for example, white daylight (color temperature is about 4600 to 5400 K). A wearer who has good visual acuity (1.0 or more) in both eyes sees the diaper 10 in a room having a certain brightness (for example, 500 to 750 lux) using a lamp at a distance of about 40 to 50 cm. Means that design elements such as colors and patterns of the first and second display areas 34a and 35a can be recognized.

  FIG. 10 is a rear view of the diaper 10 in an example of another embodiment, and FIG. 11 is a view similar to FIG. 5 in the example of another embodiment.

Referring to FIGS. 10 and 11, in this embodiment, one tape tab 20 having the same form as that shown in FIGS. 5 and 6 is attached to the waist opening edge of the rear waist region 14. The first display area 34 is positioned on the outer surface 20 a of the gripping portion 63 of the tape tab 20, and the second display area 35 is positioned on the remaining portion 64. When the diaper 10 is discarded, the diaper 10 is folded so as to be rolled up, and then the tape tab 20 is expanded toward the waist opening side and hung around the folded diaper 10, without causing excrement to leak from the waist opening, The diaper 10 can be discarded. A first display area 34 is located on the outer surface 20 a of the gripping portion 63 of the distal portion 22, and a second display area 35 is located on the outer surface 20 a of the remaining portion 64, which is the first in the external view of the diaper 10. The display area 34 and the second display area 35 can be distinguished.

  Even in such an arrangement mode, the separation portion 77 of the tape tab 20 has a shape curved outward in the thickness direction Z, and the gripping portion 63 extends further outward in the thickness direction from the separation portion 77. It can have this aspect. That is, for example, i) the entire rear waist region 14 is elasticized by the contraction force of the plurality of rear waist elastic bodies 32, and the rear waist elasticity in the arrangement region of the second proximal portion 21 </ b> B of the proximal portions 21. When the body 32 is cut or removed, ii) the second proximal portion 21B has an end flap that extends outward in the longitudinal direction Y from the rear end edge of the absorbent body of the liquid absorbing structure 12, When the rigidity is higher than that of the first proximal portion 21A, the amount of contraction by the rear waist elastic body 32 in the proximal portion 21 is such that the first proximal portion 21A> the second proximal portion 21B. The spaced-apart portion 77 that is located between the first proximal portion 21A and the second proximal portion 21B and is not fixed to the rear waist region 14 due to the difference in contraction amount between the first proximal portion 21A and the second proximal portion 21B The shape is curved outward.

  Referring to FIG. 11, in the present embodiment, the end flap 88 of the liquid absorbing structure 12 is located in the existence area of the second proximal portion 21B, and the rigidity of the existence area of the second proximal portion 21B is the first. It is higher than the rigidity of the existence area of the first proximal portion 21A, and the contraction amount of the existence area of the first proximal portion 21A is larger than the contraction amount of the existence area of the second proximal portion 21B. . Therefore, in the contracted state of the rear waist region 14, the separation portion 77 has a shape curved outward in the thickness direction Z, and the gripping portion 63 can be easily gripped at the time of disposal.

  FIG. 12 is a view similar to FIG. 8B in an example of still another embodiment. In the diaper 10 according to the present embodiment, a star-shaped central display element (display element) 90 is disposed on the outer surface of the second portion 85. The second display area 35 of the pair of tape tabs 20 includes a second display area 35 having a second display element (side display element) 91 having a star pattern of the same shape and size as the display element 90. In a state where the tape tab 20 is fixed to the outer surface of the second portion 85, the second display elements 91 are located on both sides of the center display element 90. Since the tape tab 20 has such a fastening mode, the display elements 90 and 91 are linked to form a design (three star) in which three star patterns are arranged. Thus, the display element of the 1st display area 34 or the 2nd display area 35 of the tape tab 20 is located in the outer surface of the part formed from the back-and-front waist areas 13 and 14 or the crotch area 15 in the fixed state. By having a specific design, idea or story in association with the central display element 90, the decorativeness on the appearance of the diaper 10 is improved.

  In the present embodiment, various known display elements can be used for the central display element 90 and the second display element 91. In addition to the case where the central display element 90 is disposed on the outer surface of the second portion 85 by printing or the like, for example, the central display element 90 is printed on the leak-proof sheet 42 and is visible from the outer surface of the diaper 10 through the covering sheet 43. Also good.
