The contraction of the cuff elastic body 45 separates the free edge 43a from the body side liner 40 toward the body of the wearer and fits the thighs of the wearer to prevent leakage of excrement. Further, between the side portions 44 of the cover sheet 43 and the leak-barrier sheet 42, a plurality of string-like or strand-like leg elastic bodies 46 are disposed.

  5 is a cross-sectional view taken along the line V-V in FIG. 4, and FIG. 6 is a state in which the front and rear waist regions 13 and 14 are extended in the longitudinal direction Y and the lateral direction X to the extent that wrinkles are not formed on the outer surface It is sectional drawing similar to FIG. 4 to 6 and the following description show one side portion of the diaper 10, but the other side portion also has a similar configuration.

  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 the joints (first and third joints 71 and 73). And a distal portion 22 opposite to the proximal portion 21 indirectly or directly in the thickness direction Z. The proximal portion 21 includes a first proximal portion 21A fixed to the side seam area 23 and a second proximal portion 21B spaced from the first proximal portion 21A in the lateral direction X. Have. As used herein, “proximal” means one or more portions of the tape tab 20 secured to the outer surface of the back waist region 14 and they are formed from the same or another tape substrate I mean one.

  The tape tab 20 further has an intermediate portion 61 located between the proximal portion 21 and the distal portion 22 and facing them in the thickness direction Z. The tape tab 20 which concerns on this embodiment is formed from several tape base materials (tape piece) folded in the cross-sectional Z shape, and, specifically, the 1st tape base which forms the 2nd proximal part 21B A material 51 and a second tape base 52 forming a first proximal portion 21A, an intermediate portion 61 and a distal portion 22 are provided.

  The first tape base material 51 has one end (first bent portion 56a) bent outward along the first bending line 56 in the thickness direction Z, and the bent portion 56a and the second tape The base member 52 is bonded at the second bonding portion 72. The second tape base material 52 is fixed to the side edge 18 and the first tape base material 51 in a state where it is folded in two along a second bending line 57 located substantially at the center in the length direction There is. The first proximal portion 21A is formed by fixing one end of the second tape base 52 to the side edge 18 via the third joint portion 73, and the middle portion 61 is formed by the first proximal portion 21A. The distal portion 22 extends from the second bending line 57 outward in the lateral direction X from the second bending line 57 at the outer side in the thickness direction Z of the middle portion 61. It is formed from the second bent portion 57a). The second tape substrate 52 has an outer surface 20a and an inner surface 52b opposite to the outer surface 20a. The outer surface 20 a of the second tape substrate 52 forms the outer surface of the tape tab 20 in the bent state, and the inner surface 52 a 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 located between the first and second bending lines 56, 57 in a state of being stacked on one another, and have a plurality of dot-shaped temporary fixing portions 65, Temporarily fixed by 66. The distal portion 22 further includes a grip portion 63 extending outward in the lateral direction X from the first temporary fixing portion 65 located at the first bending portion 56a. Located on the inner surface of the distal portion 62 between the tacking portions 65, 66 is a fastening zone 68 formed from the hook sheet 68a and the hook element 68b of the mechanical fastener. 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 for forming the tape tab 20 is a non-woven fiber fabric, including at least a part of a heat-sealable synthetic fiber such as polyethylene, polypropylene, polystyrene, etc., for example, having a weight of about 30 to 100 g / ^{m 2,} preferably the mass can be used about 40 g / ^{m 2} or more spunbond nonwoven.

For the first to third bonding portions 71, 72, 73, various known bonding means such as adhesion or welding such as sonic seal or heat seal can be used. A 20 g / m ² hot melt adhesive can be used. The temporary fixing portions 65 and 66 can be formed by performing known pressure treatment and pressure heat treatment, and can be formed by, for example, embossing or sonic treatment. In the case of heat treatment under pressure, if the tape tab 20 itself has thermoplastic synthetic fibers, it can be temporarily fixed more stably by heat fusion. Further, referring to FIG. 4, the temporary fixing portions 65 and 66 have a plurality of dot shapes arranged to be separated from each other in the longitudinal direction Y and the lateral direction X. In this manner, by locally arranging the temporary fixing portions 65 and 66 on the outer surface of the tape tab 20 in the stacked state, the flexibility of the tape tab 20 is improved as compared with the case where it is arranged 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 34 a on one surface forming the outer surface 20 a of the second tape base material 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 grip 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 grip 63. The first display element 34a and the second display element 35a have different displays to the extent that they can be distinguished visually. 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. 34 has a stripe pattern, and the second display area 35 has a polka dot pattern.

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

  Referring to FIG. 6, in order to easily hold the holding portion 63, the size of the holding portion 63 is preferably relatively large. Specifically, the dimension L2 in the lateral direction X is about 10 mm or more Preferably, it is about 20% or more of the dimension L1 in the lateral direction X of the distal portion 22. Thus, the relatively large length dimension of the grip portion 63 makes it easy to grip the grip portion 63 extending outward in the lateral direction X, and the diaper 10 has the decorative element 82 in a rear view. It can be easily viewed. Further, the separation dimension R in the lateral direction X between the side seam area 23 and the temporary fixing portion 65 is preferably about 5 mm or more. Thus, by forming the separation dimension R relatively large, the vicinity of the base end of the grip portion 63 is erected toward the outside in the lateral direction X by the separation portion 77, and the grip portion 63 is viewed from the front. And it becomes an aspect which protrudes outside the cross direction X in back view.

The tape tab 20 attached to the side edge 18 of the rear waist region 14 in the folded state in this manner allows the operator to hold the holding portion 63 and pull it in the pulling direction P to thereby temporarily fix the holding portion 63. The temporary fixing by 65, 66 is released. The tape tab 20 according to the present embodiment is a so-called Y-shape including a first proximal portion 21A and a second proximal portion 21B in which the proximal portions 21 fixed to the rear waist region 14 are mutually separated in the lateral direction X. Since it is a tape tab, when pulled in the pulling direction P, the peeling force acting on the first proximal portion 21A can be reduced. In addition, when the tape tab 20 has a bonding mode, the peeling force acting on the first proximal portion 21A also when the grip portion 63 is pulled and expanded inward in the lateral direction X instead of in the pulling direction P. Can be reduced. Moreover, as long as the tape tab 20 has a required peel strength, it may be formed only from one tape substrate, or may be formed from two or more tape substrates.

  Referring to FIG. 5, in the wearing state and the non-wearing state of the diaper 10, 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. At least one rear waist elastic body 32 is located in the rear waist region 14 in the placement area of the proximal portion 21 of the tape tab 20, and the contraction force of the elastic body 32 causes the proximal portion 21 to wrap around the waist. It has an undulating shape that is continuous in the direction. In the present embodiment, in a state where the tape tab 20 is not attached to the outer surface of the diaper 10, the number of the front and rear waist elastics 31, 32 such as the size, the pitch, etc. are substantially equal. Is set appropriately.

  Generally, in the case where the contraction forces are substantially equal in the front and rear waist elastic regions, as shown by phantom lines in FIG. Extend to project into. However, in the present embodiment, by locating the proximal portion 21 of the tape tab 20 at the side edge 18 of the rear waist region 14, the contraction force of the elastic region where the proximal portion 21 is present in the rear waist elastic region is reduced. As a result, the contraction force becomes lower than the elastic area of the front waist area 13 opposed in the front-rear direction. Therefore, in the side seam area 23, the amount of contraction of the front portion 23a consisting of the side edge of the front waist area 13 located inside is the amount of contraction of the rear part 23b consisting of the side edge 18 of the rear waist area 14 located outside With the amount of contraction being greater and the dimension in the lateral direction X of the front portion 23a being smaller than that of the rear portion 23b, the side seam area 23 is curved inward in the lateral direction X with the rear portion 23b as the outer side. Become.

  Thus, by having the side seam area 23 having a curved shape, the side seam area 23 and the portion adjacent to the outer side and the inner side in the lateral direction X of the side seam area 23 have a curved shape as well. The first proximal portion 21A fixed to the area 23 and the portion 81 adjacent to the outside in the lateral direction X also has a curved shape. The pinching portion 63 positioned closer to the side seam area 23 than the temporary tacking portion 65 is separated from the middle portion 61 and extends outward in the thickness direction Z since it is not joined to the middle portion 61 opposed thereto.

  With reference to FIGS. 1 and 2, since the tape tab 20 has such an aspect in which the front and rear waist areas 13 and 14 are contracted, that is, the wearing state of the diaper 10, the grip portion 63 has both side edges of the diaper 10. It will be in the state protruded to the outside of cross direction X from 10b. Therefore, when developing the tape tab 20 at the time of discarding or size adjustment of the diaper 10, there is no possibility that the gripping portion 63 overlaps with the curved intermediate portion 61 and it becomes difficult to grip and separate from the intermediate portion 61 As it is possible to easily hold the holding portion 63 extended in the longitudinal direction Z, the operability is excellent.

  Again referring to FIG. 5, while the rear waist region 14 has an undulating shape due to the plurality of gathers 80, the second proximal portion 21B fixed thereto also shrinks in the transverse direction X to have an undulating shape, The proximal portion 21B and the opposing middle portion 61 and the distal portion 22 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 so as to be localized. It is not undulating because the rigidity is high. A separated portion 77 in which the first proximal portion 21A and the second proximal portion 21B are mutually separated in the lateral direction X has a shape convex outward in the thickness direction Z because the opposing side edge 18 contracts. Have. Since the temporary fixing portion 65 is located at the first bending portion 56a, the separated portion 77 faces the vicinity of the proximal end of the gripping portion 63, and therefore the proximal end vicinity of the gripping portion 63 is a separated portion Positioned on 77, the grip 63 has a more stably extending outward in the lateral direction X. In addition, since the gripping portion 63 is located on the convexly curved separated portion 77, the temporary tacking of the temporary tacking portions 66 and 65 can be released by pulling the gripping portion 63 so as to slide in the pulling direction P. . In this manner, since the temporary tacking can be released mainly by the shearing force, the tape tab 20 can be deployed with a smaller pulling force.

  7 (a) is a plan view of the tape tab 20 in the folded state, FIG. 7 (b) is a plan view of the tape tab 20 in the expanded state, and FIG. FIG. 8B is a view showing how the tape tab 20 is fixed to the folded diaper 10. The diaper 10 shown in FIGS. 8A and 8B extends in the lateral direction X after being bent inward in the lateral direction X so that the front waist region 13 or the rear waist region 14 is on the inner side. It is a form made compact by bending the crotch area 15 to the waist area side along a folding line, and is known as a folding mode adopted 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 stripe pattern formed of a plurality of line-shaped first display elements 34a extending in the width direction of the tape tab 20. A first display area 34 having a polka dot pattern formed of a plurality of dot-like second display elements 35 a on the outer surface of the remaining portion 64 of the distal portion 22 excluding the holding portion 63. The second display area 35 is located. In general, the tape tab 20 has an intrinsic white color of a non-woven or plastic tape base like the outer surface of the diaper 10, and when the tape tab 20 is used it is difficult to visually recognize the outer contour of the diaper 10 in appearance. In some cases, it is difficult to hold the holding portion 63. In the diaper 10 according to the present embodiment, the outer contour of the tape tab 20 is facilitated by arranging the first and second display areas 34, 35 in which the outer surface 20a of the tape tab 20 is colored and / or designed. And the holding portion 63 can be held.

  In the distal portion 22 of the tape tab 20, the first display area 34 disposed 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. A person can easily recognize the relative size and range of the gripping portion 63 with respect to the entire tape tab 20. In addition, as described above, the display elements of the first display area 34 disposed on the outer surface of the gripping portion 63 for gripping when the tape tab 20 is deployed, and the second display disposed on the outer surface of the remaining portion 64 Since the display elements of the area 35 are different, the first and second display areas 34 and 35 can each function as a function display unit representing the function of the portion in which it is arranged.

  Referring to FIGS. 8 (a) and 8 (b), when discarding the diaper 10, after the wearing assistant folds the diaper 10, the user holds the folded diaper 10 with one hand and removes the tape tab 20. The holding portion 63 is held and developed while being pulled in the pulling direction P so as to press the first portion 84 composed of the front and rear waist regions 13 and 14 superimposed on each other against the second portion 85 composed of the crotch region 15. Next, when the fastening 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 fastened, the area where the second display area 35 is disposed is pressed with the thumb. The fastening zone 68 is fastened by means of. Since the fastening zone 68 is disposed on the inner surface 52b of the distal portion 22, it is difficult to visually recognize the presence zone in the appearance of the tape tab 20, but the second display zone 35 is located in the presence zone By doing this, the fastening area 68 can be pressed firmly with a finger and fastened.

  Thus, the second display area 35 is disposed at least in the presence area of the fixation area 68 in order to recognize the existence area of the fixation area 68 located on the inner surface of the distal portion 22 in the appearance of the tape tab 20 The second display area 35 may not be disposed in a portion of the distal portion 22 located inward in the lateral direction X from the fastening area 68. However, the second display area 35 is disposed on the outer surface of the entire remaining portion 64 excluding the holding portion 63 of the distal portion 22 so that the wearing assistant consciously displays the second display over the entire middle of the thumb. Since the area 35 is pressed against the outer surface of the diaper 10, the fastening zone 68 and the adjacent part thereof can be pressed to secure fastening more reliably.

  Further, in the diaper 10, since the panel members constituting the front and rear waist regions 13 and 14 have the same size and shape, it is difficult to distinguish the front and back of the diaper 10 instantaneously in 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 front and rear in the front and rear waist regions 13 and 14, before and after wearing can be easily distinguished before and after wearing, and wear operation can be performed smoothly.

  As described above, in the tape tab 20 according to the present embodiment, the first proximal portion 21A is fixed to the side seam area 23, so that the grip portion 63 is the middle portion 61 opposite thereto in the thickness direction Z. And extend outward in the lateral direction X. Furthermore, the separated portion 77 has a shape that is convexly curved outward in the thickness direction Z, and the gripping portion 63 located on the separated portion 77 is further extended outward in the lateral direction X. Therefore, in the distal portion 22, only the gripping portion 63 protrudes outward in the lateral direction X, which makes gripping easier and makes the first display area 34 easier to view. Note that the proximal portion 21 / first proximal portion 21A may not be located on the side seam area 23 as long as the placement area moves forward, and the side edge 18 of the rear waist area 14 And may be located inside the lateral direction X more than the side seam area 23.

  Referring to FIG. 7A, in the vicinity of the boundary between the first display area 34 and the second display area 35, a first temporary fixing portion 65 is located. By having such an arrangement mode of the first temporary fixing portion 65, all parts separated from the intermediate portion 61 become the holding portion 63, so that the whole can be easily held, and the first temporary fixing The fastening area 68 adjacent to the inside of the lateral direction X of the portion 65 ensures that the fastening area 68 can be pressed against the outer surface of the diaper body 10A when performing the fastening operation.

In addition, in the folded state of the tape tab 20, the total area of the first display elements 34a of the first display area 34 is larger than the total area of the second display elements 35a of the second display area 35. On the other hand, in the developed state of the tape tab 20, the total area of the first display elements 34a of the first display area 34 is smaller than the total area of the second display elements 35a of the second display area 35. Thus, the tape tab 20 is used because 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. In this case, when the tape tab 20 is developed and attached to the outer surface of the diaper 10, the second display element 35a is more easily recognized. Thus, for example,
By making the decorativeness (designability) of the second display element 35 b higher than that of the first display element 34 a, the second display area 35 appears relatively large in the fastened state of the tape tab 20, so The 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 the state in which the tape tab 20 is expanded, for example, a plurality of dot-shaped polka dots as the second display element 35a, discontinuous triangles, stars, rectangles, etc. In the case of using a graphic of character, it is preferable that the first display element 34a of the first display area 34 be a graphic of continuity 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 boundaries between the two display areas 34 and 35 can be grasped.

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

  In the first area 64A, the second display element 35a printed on the outer surface 20a, which is one surface of the second tape substrate 52, is transmitted by transmitting the white or milky hook sheet 68a disposed on the inner surface 52b. Compared to the second area 64B, it is more clearly visible. On the other hand, in the third area 64C, since the first tape base 51 is disposed so as to cover the second tape base 52, the visibility of the second display element 35a is reduced compared to the second area 64B. . Thus, the correlation of the visibility of the second display element 35a in each of the areas 64A, 64B, 64C of the second display area 35 is such that the first area 64A> the second area 64B> the third area 64C. The color of the second display area 35 is increased from the proximal portion 21 side toward the grip portion 63 side. Therefore, the shades of color of the areas 64A to 64C can be made different without controlling the color of the second display element 35a itself. While the tape tab 20 is improved in design by the contrast due to the difference in color density in the second display area 35, the wearing assistant easily grasps the area where the fastening area 68 in the entire second display area 35 is disposed. be able to.

  In the present embodiment, the first display area 34 is disposed on the outer surface 20 a of the knob 63, but the first display area 34 is disposed on the inner surface of the knob 63 as long as it is visible from the outside. It is also good. In the contracted state of the rear waist region 14, the separated portion 77 has a shape that is convexly curved outward in the thickness direction Z, and the grip portion 63 located on the separated portion 77 extends outward in the lateral direction X As a result, the inner surface of the grip portion 63 is exposed. Therefore, also by disposing the first display area 34 on the inner surface of the grip section 63, the wearer can grasp the grip section 63, and in that respect, the first display area 34 located on the outer surface 20a. May be seen through so as to be visible from the inner side. Furthermore, on the outer surface 20a and the inner surface 52b of the grip portion 63, decorative elements having different designs may be arranged.

  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 in a state in which one tape substrate is folded in two and the proximal portion 21 fixed to the side edge 18 of the rear waist region 14 in the thickness direction Z And a distal portion 22 opposed to the proximal portion 21. The proximal portion 21 and the distal portion 22 are temporarily fixed to each other via the temporary fixing portions 65 and 66, and the tape tab 20 can be deployed by pulling the holding 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 , And a second display area 35 having a second display element 35a (not shown) different in form from the first display element 34a. Thus, even if the tape tab 20 is a mode in which a single tape substrate is folded in two, the first display area 34 and the second display area 35 can be distinguished in the appearance of the diaper 10.

  In the present specification, "the first and second display areas 34, 35 are visible" means that the room has a constant brightness by a fluorescent light, for example, fluorescence of daylight (color temperature of about 4600 to 5400 K) In a room having a certain brightness (for example, 500 to 750 lux) using a lamp, a wearer having good vision (1.0 or more) of both eyes looks at the diaper 10 at a separation distance of about 40 to 50 cm. It 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 according to another embodiment, and FIG. 11 is a view similar to FIG. 5 according to another embodiment.

Referring to FIGS. 10 and 11, in the present 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 area 14. The first display area 34 is located on the outer surface 20 a of the grip portion 63 of the tape tab 20, and the second display area 35 is located on the remaining portion 64. When discarding the diaper 10, the diaper 10 is folded so as to be rolled, and then the tape tab 20 is unfolded toward the waist opening side and wound around the folded diaper 10 without leaking waste 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 grip 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. The display area 34 and the second display area 35 can be distinguished.

  Further, even in such an arrangement mode, the separated portion 77 of the tape tab 20 has a shape curved outward in the thickness direction Z, and the gripping portion 63 extends further in the thickness direction from the separated portion 77. Can have the following aspect. That is, for example, i) the entire rear waist region 14 is elasticized by the contraction force of the plurality of rear waist elastics 32, and the rear waist elastic in the arrangement region of the second proximal portion 21B of the proximal portion 21 When the body 32 is cut or removed, ii) the second proximal portion 21B has an end flap extending outward in the longitudinal direction Y from the rear end edge of the absorbent body of the liquid absorbent structure 12, In the case where the rigidity is higher than the first proximal portion 21A or the like, the amount of contraction by the rear waist elastic body 32 at the proximal portion 21 is: first proximal portion 21A> second proximal portion 21B In the thickness direction Z, the separated portions 77 which are related to each other and are not fixed to the rear waist region 14 between the first proximal portion 21A and the second proximal portion 21B due to the difference in the amount of contraction It has a shape that curves outward.

  Referring to FIG. 11, in the present embodiment, the end flap 88 of the liquid absorbent structure 12 is located in the region where the second proximal portion 21B is present, and the rigidity of the region where the second proximal portion 21B is present is The rigidity of the first proximal part 21A is larger than the rigidity of the proximal part 21A, and the contraction of the first proximal part 21A is larger than the contraction of the second proximal part 21B. . Therefore, in the contracted state of the rear waist region 14, the separated portion 77 has a shape curved outward in the thickness direction Z, and can easily grip the grip portion 63 at the time of disposal.
