It is possible to maintain a well-rounded shape so that no matter is exposed by opening 24. 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.

  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 facing surface side and outer surface sheets 28 and 30 positioned on the non-skin facing surface side, respectively. A plurality of string-shaped or strand-shaped front waist elastic bodies 31 extending in the lateral direction are attached between the inner and outer surface sheets 27 and 28 of the front waist sheet 25 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 absorbing structure 12 has a rectangular shape and includes a front end portion 12A, a rear end portion 12B, and a central portion 12C positioned between the front and rear end portions 12A and 12B.

A sleeve-like free edge 43a that is not fixed to the inner surface of the body-side liner 40 is located on the outer edge of the both side parts 44, and a plurality of string-like shapes extending in the longitudinal direction Y are inside the free edge 43a. Or the strand-like cuff elastic body 45 is arrange | positioned so that it can shrink | contract in the expansion | extension state. 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.

  4 is a side view of the diaper 10, FIG. 5 is a cross-sectional view taken along the line VV of FIG. 4, and FIG. 6 shows the longitudinal direction Y and the waist regions 13 and 14 to the extent that no wrinkles are formed on the outer surface. It is sectional drawing similar to FIG. 5 in the state extended | stretched in the horizontal direction X. 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.

  Referring to FIGS. 4 to 6, the tape tab 20 has a thickness direction Z and the proximal portion 21 fixed to the outer surface of the side edge portion 18 of the rear waist region 14 via the first joint portion 71. It has a proximal portion 21 and a distal portion 22 that is indirectly or directly opposed in the 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.

  The first tape substrate 51 has one end portion (folded portion 56a) bent along the first bent line 56 to the outside in the thickness direction, and the bent portion 56a and the second tape substrate 52 are bent. Are joined at the joint (third joint 73). 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 joint portion (second joint portion 72), and the intermediate portion 61 is the first portion. The distal portion 22 is formed from a portion extending inward in the lateral direction X from the proximal portion 21A, and the distal portion 22 extends outward in the lateral direction X from the second folding line 57 outside the intermediate portion 61 in the thickness direction Z. It is formed from the part which extends.

  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 stacked state, 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 temporary fixing portion 65 located at the 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 22 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 the adhesion means is used, the mass is about 5 A hot melt adhesive of ˜20 g / m ² 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. In the case of performing the heat treatment under pressure, when the tape tab 20 itself has thermoplastic synthetic fibers, 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. 6, the tape tab 20 attached to the side edge portion 18 of the rear waist region 14 in the folded state as described above, the operator holds the holding portion 63 and pulls it in the pulling direction P. Thus, the temporary fixing by the temporary fixing portions 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, the front and rear waist regions 13, 14 are in a contracted state, that is, in a 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 protruded to the outer side of the horizontal direction X from the part 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 due to 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. 2 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. There is no undulation due to locally 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 bent portion 56 a, the separation portion 77 faces the vicinity of the proximal end of the gripping portion 63, so that the vicinity of the proximal end of the gripping portion 63 is above the separation portion 77. The gripping part 63 is located in the position of the lateral direction X and extends more stably. 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.

  In order for the tape tab 20 to have such an aspect, that is, in order to make the side seam region 23 have a curved shape, the contraction force of the front waist elastic region is reduced in the state where the tape tab 20 is not attached to the diaper 10. It is preferable to set higher than the contraction force of the waist elastic region. Specifically, the fineness, expansion ratio, and pitch of the front and rear waist elastic bodies 31, 32 are set so that the contraction force of the front waist elastic region is about 1.1 to 2.8 times the contraction force of the rear waist elastic region. It is preferable to adjust appropriately. Thus, by making the contraction force of the front waist elastic region higher than that of the rear waist region, the effect of reducing the contraction force of the rear waist elastic region by fixing the proximal portion 21 of the tape tab 20 is combined. Thus, in the side seam region 23, the contraction amount of the front portion 23a is more reliably larger than the contraction amount of the rear portion 23b, and the side seam region 23 can be curved. In order to have such a technical effect, the amount of contraction of the portion where the proximal portion 21 is located in the rear waist elastic region is lower than the amount of contraction of the portion of the front waist elastic region facing the elastic region in the front-rear direction. The contraction force of the other part in the front and rear waist elastic region may not be such a correlation.

  Referring to FIGS. 1 and 2 again, the side seam region 23 and its adjacent portion are curved, so that the gripping portion 63 extends outward in the lateral direction X, and the outer shape of the diaper 10 is also viewed from the front. The contour can be visually recognized. Thereby, the wearer can obtain a sense of security that the tape tab 20 can be easily held and deployed before and during use. In addition, a decorative element 82 composed of a plurality of line patterns extending in the vertical direction Y is disposed on the outer surface of the gripping portion 63 of the tape tab 20. In the diaper 10, since the panel members constituting the front and rear waist regions 13 and 14 are the same shape, it is difficult to instantaneously determine the front and rear of the diaper 10 in appearance, and thus, on the outer surface of the tape tab 20, as described above. By arranging the decorative element 82, the wearer / wearing assistant can determine the front and back of the diaper 10. 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.

  In the present embodiment, the decorative element 82 is disposed only on the outer surface of the gripping portion 63, so that the gripping portion 63 has no pattern and white in the front view of the diaper 10, and the decorative element 82 and the same in the rear view of the diaper 10. As a result, the front and rear waist regions 13 and 14 can be easily distinguished. As long as such a technical effect is exhibited, a decorative element having a different form from the decorative element applied to the outer surface is arranged on the inner surface of the gripping portion 63, or the decorative element is arranged only on the inner surface with no pattern on the outer surface and white. May be. As the decorative element 82 arranged in the gripping portion 63, various known decorative elements such as a dot shape, a wavy shape, a geometric shape, a character, a pattern, a trademark, and a character are used in addition to the line pattern (striped pattern). Can do. Further, by forming the tape base material of the tape tab 20 from a nonwoven fabric, it is possible to easily print decorations with a wide variety of colors and designs.

  Further, in order to easily grip the gripping portion 63, the size of the gripping portion 63 is preferably relatively large. Specifically, the dimension L2 in the lateral direction X is about 10 mm or more, and the distal portion It is preferably about 20% or more of the dimension L1 of 22 in the lateral direction X. 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.

  As described above, in the non-wearing state and the wearing state of the diaper 10, the gripping portion 63 of the tape tab 20 distinguishes the function as an operation portion that grips when the tape tab 20 is unfolded and the front and back sides of the diaper 10. Indicator function. The gripping part 63 may be divided into a plurality of parts as long as both functions are exhibited, or may be formed from a composite sheet in which a plurality of nonwoven fabrics and plastic films are laminated.

FIG. 7 is a cross-sectional view of the tape tab 20 similar to FIG. 5 according to the second embodiment. Referring to FIG. 7, in this embodiment, the tape tab 20 is fixed to the side edge 18 of the rear waist region 14 at a proximal portion 21 extending inward in the lateral direction X from a portion overlapping the side seam region 23. . In the tape tab 20 according to the present embodiment, since the side seam region 23 and the portion adjacent thereto have a curved shape, the position of the proximal portion 21 fixed to them also has a curved shape.

  The gripping portion 63 of the distal portion 22 is not fixed to the curved side seam region 23 and the adjacent portion, and the temporary fixing portion 65 is separated from the side seam region 23. The vicinity of the proximal end of the holding portion 63 extends outward in the lateral direction X by a curved portion. Therefore, also in the present embodiment, as in the first embodiment, the gripping portion 63 can be easily visually recognized by extending outward in the lateral direction X in the front view and the rear view of the diaper 10.

<Third Embodiment>
FIG. 8 is a cross-sectional view of the tape tab 20 similar to FIG. 5 in the diaper according to the third embodiment.
