Fig. 11 and Fig. 12 are attached or It is a front view of a pants state. The paper diaper of the present embodiment has an intermediate part 10c and side flap parts 11 and 12 projecting from both sides thereof, and a belt-like waist part 10 wound around the waist of the wearer, and a rear end part of the waist part It is composed of an absorbent main body 20 which is connected to the 10 middle part 10c and is mounted so as to cover from the back side through the crotch part to the abdominal side.

[0017] The absorbent main body 20 has a rectangular shape that extends in the front-rear direction of the product, and is provided along the center in the width direction of the product so as to cover the abdomen, crotch, and buttocks of the wearer. The end portion 20B is fixed to the inner surface of the intermediate portion 10c of the waistline portion 10 so as not to be detachable by hot melt bonding or the like.

[0018] As will be described later, the rear end portion 20B of the absorbent main body 20 can be detachably connected to the inner surface of the intermediate portion 10c of the waistline portion 10 using an adhesive tape, a target tape, or the like. . Remove only dirty absorbent body 20 when changing diapers, and install a new absorbent body 20!

[0019] The absorbent main body 20 receives excrement and absorbs and holds liquid components. As shown in FIGS. 3 to 5, the absorbent main body 20 includes a liquid-permeable top sheet 21 that forms a use surface in contact with the body. The liquid-impermeable sheet 23 and the absorber 22 interposed between them have a structure in which the top sheet 21 and the liquid-impermeable sheet 23 are bonded together by hot-melt bonding or the like at the peripheral edge. is doing.

[0020] In addition, a flap forming member that does not have a stretchability smaller than that of the waistline portion 10 may be attached to an end portion of the absorbent main body 20 that faces the end portion to which the waistline portion 10 is attached. In this way, if small flaps are provided on both sides near the end of the absorbent main body on the opposite side of the waistline portion 10, the connecting portions when aligning the connecting portions when mounting as a fastening type It is preferable that the knob portion can be used.

[0021] The top sheet 21 can be formed from a nonwoven fabric, a film having a liquid permeable opening, a net sheet, etc., and the liquid impermeable sheet 23 can be formed from a plastic sheet such as a polyethylene sheet. Can do. An outer nonwoven fabric 24 such as a water-repellent nonwoven fabric is bonded to the outer surface of the liquid-impermeable sheet 23, and this outer nonwoven fabric 24 serves as a connecting portion of the waistline portion 10 in the illustrated embodiment. From the viewpoint of the exterior nonwoven fabric 24 exhibits a sufficient engaging force, air-through nonwoven fabric as the preferred tool also types of basis weight of 15 to 50 g / m ^2, points Bond nonwoven, spun bonded nonwoven fabric, SMS nonwoven fabric Is preferred. In this case, a force S can be applied to emboss and reinforce at least the connecting portion (for example, the front side of the front-rear direction center, etc., as a whole) of the exterior nonwoven fabric 24. Reference numeral 25 in the figure indicates a recess formed by embossing. In the embossing process, the exterior nonwoven fabric 24 and the liquid-impermeable sheet 23 are bonded together, and then pressed from the exterior nonwoven fabric 24 side with a convex emboss roll. The roll facing the convex embossing roll may be a concave embossing roll in which a concave portion corresponding to the convex portion of the convex embossing roll is formed, or a rubber roll having a flexibility that allows the convex portion of the convex embossing roll to be pushed in. However, it is not particularly limited. The embossed area, which is the adhesion point area of the convex portion of the convex boss roll, is 5 to 50%, preferably 5 to 40%, and particularly preferably 10 to 30%. If the embossed area is less than 5%, the adhesive strength is insufficient, and if it is more than 50%, the sheet obtained by embossing may become hard and the texture may be impaired. As an emboss pattern to be provided as a connecting portion, any pattern such as a dot shape, a staggered shape, a lattice shape, or a linear shape can be selected.

[0022] Regardless of whether or not the exterior is a non-woven fabric, a target tape 26 on which a large number of loops with hooks are formed may be provided on the sheet surface, and this may be used as a connecting portion. The target tape 26 is preferably provided on a part, for example, a front side of the center in the front-rear direction, but may be provided on the whole.

[0023] As the absorbent body 22, in addition to the one in which short fibers are stacked, such as cotton-like pulp, one made of an aggregate of filaments can be used. Filament aggregate is cellulose acetate It can be formed by opening a tow (fiber bundle). If necessary, the absorbent body 22 may contain a superabsorbent polymer (SAP), or may be wrapped with a crepe paper nonwoven fabric or the like with a force S.

[0024] Further, on the both sides in the width direction of the absorbent main body 20, barrier one-strength hose 30, 30 that stands up with respect to the top sheet 21 when mounted is provided. More specifically, the widthwise outer edge 31a of the belt-like barrier sheet 31 is fixed to the surface of the top sheet 21 by hot-melt bonding or the like over the entire longitudinal direction on both sides of the absorbent body 20, and the center in the width direction. The side portion 31b is fixed to the surface of the top sheet 21 by hot melt bonding or the like at the front and rear end portions of the absorbent main body 20, and is not fixed at the middle portion in the longitudinal direction. Further, the non-fixed portion 31b has a double structure by folding the distal end side portion and sticking it to the proximal end portion. Between the sheets of the double structure portion, an elongated elastic elastic member 32 such as thread rubber is provided. Is clamped and fixed along the longitudinal direction in the stretched state. In use, the non-fixed portion 31b of the barrier sheet 31 is erected away from the top sheet 21 by the contraction force of the elastic expansion / contraction member 32, and the distal end thereof is in close contact with the wearer's leg. As a result, excrement moving in the lateral direction along the top sheet 21 is prevented, and side leakage is prevented. A water-repellent nonwoven fabric can be suitably used as the nore sheet 31.

[0025] The waistline portion 10 is a belt-like member that is a portion from a waist opening through which the wearer's torso is passed to a leg opening through which the wearer's leg is passed. The waistline portion 10 includes an intermediate portion 10c corresponding to the absorbent main body 20 in the product width direction, and first and second side flap portions 11 and 12 projecting on both sides thereof, and each side flap portion 11, 12 has base end side expansion and contraction parts 11 x and 12 x and front end side connection parts l lf and 12 f. The stretchable parts lx and 12x are the parts that provide stretchability in the waistline direction on both sides of the product, and the connecting parts llf and 12f are the parts that are connected when assembling the pants.

[0026] More specifically, as can be understood from the cross-sectional views of FIGS. 6 to 9, the waistline portion 10 is based on the main body sheet 13 over its entirety, and each portion has a function by adding members. It is. More specifically, the main body sheet 13 is formed by stacking a plurality of non-woven fabrics 13a and 13b and fixed by a hot melt adhesive or the like, and between these non-woven fabrics 13a and 13b, the middle portion 10c of the waistline portion and the expansion and contraction are provided. The elastic elastic member 14 stretches along the width direction over the part lx, 12x It is clamped and fixed in the state.

[0027] Particularly, in the waistline portion shown in the figure, in the waist portion W defined as the vertical range from the upper end edge (being the edge of the waist opening) to the vicinity of the upper end of the absorbent main body 20, the middle portion 10c of the waistline portion The elastic elastic member 14 is continuously provided over the entire waist direction of the lx, 12x and the elastic part 14 at the lower waist U defined as the lower part of the waist part W. 14 is provided so that the expansion and contraction force acts only on both sides thereof except for the intermediate portion 10c in the width direction overlapping the absorbent main body 20. In addition to the configuration in which the elastic expansion / contraction member 14 exists only on both sides, the elastic expansion / contraction member is formed over the entire waist direction of the middle portion 10c of the waist portion 10 and the stretch portions l lx and 12x. Although 14 exists, the elastic part 14 is cut in the intermediate part 10c, and the structure in which the elastic force is not applied is also included. If the elastic stretchable member 14 is located in the vicinity of the absorbent main body 20 as long as it does not need to exactly match the outline of the absorbent main body 20, the elastic stretchable member 14 is separated even if it overlaps the absorbent main body 20. It doesn't matter.

[0028] As the elastic elastic member 14, a thread rubber or elastic foam band, a film-like elastic body, a net-like elastic body, or the like can be used. It is preferable to install in fi. Specifically, thread rubber with a thickness of 300 ~; 1200dtex, preferably 400 ~; about 100 Odtex, 5-7 pieces at intervals of 4-6mm on the waist W, and 3-8mm on the lower back It is preferable to fix at a spacing of about 10 to 30 and an elongation rate of about 150 to 400%, preferably about 200 to 300%.

[0029] In each of the connecting portions llf and 12f in the first and second side flap portions 11 and 12, a large number of hook-shaped protrusions such as hooks and J-shaped are arranged on the inner surface of the main body sheet 13. The hook tape (male material of the mechanical fastener) 15 is pasted by hot-melt bonding or the like over almost the entire vertical direction.

[0030] Characteristically, in each of the side flap portions 11 and 12, a perforation 16 extending toward the intermediate portion 10c along the product width direction is formed along the vertical intermediate force at the front end edge. . The perforation 16 is a force that can be extended to the boundary with the intermediate portion 10c, as shown in the example, to the middle in the width direction of the expansion / contraction portions l lx, 12x, specifically from the front edge side 1/3 to 1 / It preferably extends to a range of 2. In addition, the vertical position of the perforation 16 is the upper and lower in the illustrated example. For example, the force can be provided along the boundary between the waist portion W and the lower waist U.

[0031] In the present embodiment, the form of one perforation 16 is described. However, in the case of a form having a plurality of perforations 16 that does not exclude any form having a plurality of perforations 16. In addition, the size can be adjusted more freely. When a plurality of perforations are provided, the perforation forms (perforation width, perforation pitch, etc.) may be the same perforation form or different perforation forms. Anyway!

[0032] As one preferred form, in a state where the perforation 16 is cut off, the expansion stress in the product width direction of the portion corresponding to the upper side of the perforation 16 and the expansion stress in the product width direction of the portion corresponding to the lower side of the perforation are different. Such a configuration is also proposed. For example, it is possible to increase the force S in the product width direction of the portion corresponding to the upper side of the perforation 16 as compared with the portion corresponding to the lower side of the perforation 16. More specifically, the expansion stress in the product width direction of the portion corresponding to the upper side of the perforation 16 is set to about 1.5 to 2.5 times the expansion stress in the product width direction of the portion corresponding to the lower side of the perforation 16. I can do it. The definition of the stretching stress is as described above. In order to make the expansion and contraction stress large and small, the number, thickness, stretch ratio, etc. of the elastic stretch members may be made different between the upper side and the lower side of the perforation 16.

[0033] Further, in the present embodiment, the lower edge portions of the side flap portions 11, 12 have a curved shape in which the direction gradually changes toward the crotch side as the absorbent main body 20 is approached in the vicinity of the absorbent main body 20. There is no. As a result, the force in the vicinity of the intersection between the lower edge of each side flap portion 11, 12 and the side edge of the absorbent main body 20 fits around the leg of the wearer. Further, along the curved portions of the side flap portions 11 and 12, an elongated elastic elastic member 17 such as rubber thread is fixed in an extended state, and the top sheet 21 and the liquid on the both sides of the absorbent main body 20 are not liquid. The part that forms at least the edge of the redder opening LO along the front-rear direction with the permeable sheet 23, that is, the rear body part of the waist part 10 from the intersection with the front part of the waist part 10 in the illustrated embodiment A slender elastic elastic member 27 such as rubber thread is fixed in an extended state up to the position where it intersects with. As a result, the entire edge of the redder opening LO is expanded and contracted in the direction around the leg.

[0034] On the other hand, a disposable diaper that can be used as a pants-type or fixed-type configured by force, It can be assembled as follows, and it is possible to use it through both feet on a pre-formed pants-type as well as a method of connecting the parts applied to the body in the deployed state.

Yes

That is, in the former method of use, after the center in the width direction of the absorbent main body 20 at the waistline portion is aligned with the center in the left-right direction at the waist on the back side, for example, as shown in FIG. Bring the front part of the main body 20 to the ventral side, and bring the first side flap 11 and the second side flap 12 onto it as shown in Figs. 20 Engage with outer surface. As a result, the waistline portion 10 is wound around the waistline, the crotch portion and the front and back sides thereof are covered by the absorbent main body 20, and the mounting is completed.

[0036] The same applies to the method of use in which the pants are formed in advance. That is, as shown in FIG. 10, first, the front side portion of the absorbent main body 20 is brought to the ventral side, and then the first side flap 11 and the second side flap 12 as shown in FIGS. To engage the male members 15 and 16 on the inner surface with the outer surface of the absorbent main body 20. As a result, an annular waistline and a monthly opening WO are formed, and leg openings LO are formed on both lower sides of the absorbent main body 20. The wearer wears both legs through the torso opening WO and the both leg openings LO.

[0037] Characteristically, in these modes of use, the side flap portions 11 and 12 can be divided into two upper and lower stages by separating (splitting) the perforations 16 as necessary. , 12 can be connected to multiple locations. In addition, as shown in FIG. 12, the portions llu, ib, 12u, 12b that have been subjected to the IJ in the upper and lower stages can be connected to the absorbent main body 20 at different angles. In particular, the upper part 11 u, 12 u of the parts divided into two upper and lower parts as shown in the figure is connected to the front end of the absorbent main body 20 along the width direction, while the lower part 11 b, 12 b is more It is preferable to connect diagonally toward the portion close to the crotch side because the absorbent main body 20 can be lifted along the buttocks and fit to the body.

[0038] <Second Embodiment>

FIG. 14 is a plan view of the inner side of the disposable diaper according to the second embodiment, FIG. 15i is a plan view of the outer side of the deployed state, and FIG. 24 is a front view of the wearing state or the pants state.

[0039] In the second embodiment, the inner surface of the front end of the absorbent main body 20 is substantially entirely in the width direction. The male material 26i of the mechanical fastener is affixed by hot melt bonding or the like, and the female material 26x of the mechanical fastener is affixed to the outer surface by hot melt adhesion or the like over substantially the entire width direction. As the male material 26i of the mechanical fastener, it is possible to use a material in which a large number of hooks such as hooks and J-shapes are arranged on the entire surface of the seat. Further, as the female material 26x, it is possible to use a material in which a large number of loops in which a male hook is entangled are formed on the entire sheet surface. Further, by forming a portion where the male material is locked with a non-woven fabric, the non-woven fabric can be used as a female material. In this case, embossing can be applied to the non-woven fabric portion to be a female material to reinforce it.

[0040] As can be understood from the cross-sectional views of FIGS. 19 to 22, the waistline portion 10 of the second embodiment is based on the same structure as that of the first embodiment. It is formed to be somewhat longer than the waistline, and the male fasteners 15i of mechanical fasteners are formed on the inner surface of the main body sheet 13 on the upper and lower sides of the connecting portions llf and 12f in the first and second side flap portions 11 and 12. A female material 15x of a mechanical fastener is pasted on the outer surface by hot melt bonding or the like over the entire surface. As the female material 15x, a material in which a large number of loops in which a male hook is entangled is formed on the entire sheet surface can be used. Moreover, this nonwoven fabric can also be utilized as a female material by forming the part which a male material is latched with a nonwoven fabric. In this case, embossing can be applied to the non-woven fabric portion that becomes the female material to reinforce it.

[0041] In the second embodiment, the length of the connecting portion l lf in the first side flap 11 1 in the waistline direction is longer than the width of the absorbent main body 20, and the second side flap 11 1 The side flaps 1 2 are formed longer than the length in the waistline direction. This is based on the assumption that the first procedure is to bring the first side flap 1 1 into the ventral side as the main procedure, and it can be assembled by other procedures. It can be installed. However, as shown in FIGS. 31 and 32, it is also possible to form the first and second side flap portions 11 and 12 symmetrically. In the case of left-right symmetry, there is an advantage in that it is easy to mount from either side, or that it can be mounted from either side is easy. On the other hand, in the case of left-right asymmetry, it is especially useful for specific audiences and specific usage methods! /, More easily used, for example, right-handed people who are majority! There is an advantage that can be made.

Since the other points are the same as those of the first embodiment, the same reference numerals as those of the first embodiment are used in the drawing, and the description thereof is omitted.

[0042] On the other hand, the disposable diaper according to the second embodiment configured with force and comb can be assembled as follows, and is formed into a pants shape in advance by using only the parts applied to the body in the unfolded state. It is also possible to use it through both feet.

That is, in the former usage, after the center in the width direction of the absorbent main body 20 at the waistline portion is aligned with the center in the left-right direction at the waist on the back side, first, for example, as shown in FIG. Flap part 11 is turned to the ventral side, and the center of the outer circumference of female material 15x is pressed to the center of the abdomen in the left-right direction, and then the second side flap part 12 is turned to the ventral side to The male member 15i is locked to the female member 15x on the outer surface of the first side flap portion 11. As a result, the first and second side flaps 11 and 12 are connected at the tip portion to form an annular waistline portion and a waist opening WO, and on the outer surface at the center of the left and right direction of the abdomen. An integrated female material portion is formed which includes the female material 15x on the outer surface of the 1 side flap portion 11 and the female material 15x on the second side flap portion 12. Thereafter, the absorbent main body 20 is turned to the abdomen through the crotch portion of the wearer, and the male material 26i provided on the inner surface of the front end portion is locked to the female material portions 15x and 15x. As a result, as shown in FIG. 24, a redder opening LO is formed, and the crotch part and both front and rear sides thereof are covered by the absorbent main body 20, and the mounting is completed.

[0043] The same applies to the method of using the pants-type in advance. That is, as shown in FIG. 23, first, the first side flap portion 11 is folded back to the absorbent main body 20 side, and the center of the outer circumference of the female material 15x is set to the center of the absorbent main body 20 in the width direction. After the alignment, the second side flap portion 12 is folded back to the absorbent main body 20 side, and the male material 15i on the inner surface is locked to the female material 15x on the outer surface of the first side flap portion 11. At this time, positioning is performed so that the stretchable part is symmetrical. As a result, the first and second side flaps 11 and 12 are connected at the front end portion to form an annular waistline portion and a waist opening WO, and on the outer surface of the front body in the waistline direction center. An integrated female material portion is formed of the female material 15x on the outer surface of the 1 side flap portion 11 and the female material 15x on the second side flap portion 12. Do it Thereafter, the absorbent main body 20 is passed through the crotch portion to the front body side, and the male material 26i provided on the inner surface of the front end portion is locked to the female material portion.

[0044] Further, in the above procedure, the second side flap is first brought to the front body side, the first side flap portion 11 is brought thereon, and the male material 15i on the inner surface thereof is attached to the second side flap portion 12. It can also be locked to the outer female material 15x.

Furthermore, as shown in FIG. 25, first bring the front part of the absorbent main body 20 to the front body side, and then bring the first side flap 11 into it as shown in FIG. Side flap 1 1 After engaging the male material 15i on the inner surface with the female material 26x on the outer surface of the absorbent main body 20, bring the second side flap 12 onto it further, and connect the male material 15i on the inner surface to the first side flap. 1 1 It is also possible to take a procedure of locking to the female material 15x on the outer surface.

[0045] Conversely, the second side flap 12 is brought before the first side flap 11 and the male material 15i on the inner surface is locked to the female material 26x on the outer surface of the absorbent main body 20. The first side flap 1 1 is brought in, and the male material 15i on the inner surface is locked to the integral female material portion consisting of the female material 15x on the outer surface of the second side flap 12 and the female material 26x on the outer surface of the absorbent main body 20. One hand can be taken.

[0046] In the above example, the male material of the mechanical fastener is provided in all the connecting portions on the inner surface side of the product. Therefore, even if it is assembled according to any of the above procedures, the male material of any mechanical fastener may come into contact with the body, which may deteriorate the wearing feeling. For this reason, it is preferable to use a material having a soft feel as the male material of the mechanical fastener.

[0047] As one preferred form, as shown in FIGS. 27 to 29, a part or all of the male materials 26i, 15i of the mechanical fastener provided on the inner surface side of the product is attached and detached by the covering sheet 40. Suggest to coat. The covering sheet 40 can be formed using the aforementioned female material or non-woven fabric. The user can avoid the deterioration of the wearing feeling due to the mechanical fastener by sticking such a covering sheet 40 as necessary.

[0048] Further, as shown in FIG. 30 in which a separate cover sheet 40 is not used, the front end force of the absorbent main body 20 also extends the cover sheet 24x, and the cover sheet 24x is folded back to the inner surface side. It is also preferable to detachably cover the male material located on the innermost side during mounting. The covering sheet 24x shown in the figure extends the non-woven fabric 24 that forms the outer surface of the absorbent body 20. It is possible to separately provide force S, female material, etc. formed by the above.

[0049] Further, it is proposed to change the idea and use all female materials on the product inner surface side and all male materials on the product outer surface side. In this case, it is desirable that a part or all of the male material provided on the outer surface side of the product is detachably covered with a separate covering sheet. As a result, it is possible to avoid the deterioration of the wearing feeling and to cover the male material of the mechanical fastener exposed on the outer surface of the product with the covering sheet, thereby preventing the engagement with the clothes contacting the outer surface of the product. Even in this case, as in the case where the male material is provided on the inner surface side of the product, the front end force covering sheet of the absorbent main body 20 is extended, and this covering sheet is folded back to the outer surface side so that the male material positioned on the outermost side is attached. A force S is used to configure the cover so that it can be freely attached and detached.

[0050] <Third embodiment>

FIG. 33 shows a disposable diaper according to the third embodiment. Characteristically, the absorbent main body 20 is composed of a front part 20F located on the front side in the front-rear direction and a rear part 20B located on the rear side. Has been. As can be seen from FIGS. 34 to 36, each of the front portion 20F and the rear portion 20B includes a liquid-permeable top sheet 21 that forms a use surface in contact with the body, a liquid-impermeable sheet 23, and these. It is comprised from the absorber 22 interposed between these. An exterior nonwoven fabric similar to that of the first embodiment can be bonded to the outer surface of the liquid-impermeable sheet 23.

[0051] As characteristically, as can be seen from FIGS. 36, 37 and 38, the rear end F1 of the front portion 20F and the front end F2 of the rear portion 20B are detachably connected by a connecting means. Is done. The connecting means can be selected as appropriate, but from the viewpoint of ease of manufacture, a mechanical fastener (surface fastener), an adhesive material, and the like are preferable. In the case of a mechanical fastener, a male material having a large number of hooks, J-shaped hooks, etc. arranged on the entire surface of the seat is provided in one connecting portion F1, and the female material to which the male material is entangled and locked is connected to the other connecting portion. Can be provided in F2. As the female material, a material in which a large number of loops are formed on the entire sheet surface can be used. In addition, the nonwoven fabric can be used as a female material by forming the connecting portion F2 to which the male material is locked by a nonwoven fabric. The male material and female material of the mechanical fastener can be bonded and fixed to the front portion 20F or the rear portion 20B with a hot melt adhesive or the like.

[0052] When an adhesive is used, each of the connecting portions Fl, F2 of the front portion 20F and the rear portion 20B That is, either one may be provided with an adhesive layer, and the other connecting portion may be formed of the material itself, but it is preferable to provide a resin film that adheres so that the adhesive can be peeled off and reattached. The resin film can be adhered and fixed to the front portion 20F or the rear portion 20B with a hot melt adhesive or the like.

[0053] The connecting position between the front portion 20F and the rear portion 20B is preferably located in the force crotch portion CR that can be determined as appropriate. The crotch CR in a product is not a general rule, but in a normal product, it is determined as the central part in the front-rear direction and its vicinity. The specific connection position can be arranged so as to be included in the central area when the product is divided into three in the longitudinal direction.

[0054] In the illustrated embodiment, a force is adopted in which the outer portion of the rear portion 20B and the inner surface of the front portion 20F are overlapped and joined with the rear portion 20B being the inner side and the front portion 20F being the outer side. It is also possible to connect in the opposite state. When the front part 20F and the rear part 20B are overlapped as shown in the figure, the absorber 12 of the front part 20F and the absorber 12 of the rear part 20B should not overlap when the connecting part is slipped. Although it is desirable, in order to improve the absorption of the crotch CR, it may be configured to overlap to some extent, for example, about 1 to 5 cm! /.

Furthermore, in the disposable diaper of the third embodiment, as shown in FIGS. 35 and 38, the rear side portion 20B is the lower end portion F4 at the center in the width direction of the inner surface of the waistline portion 10 at the upper end portion F3 of the outer surface. It is detachably connected to. In the illustrated example, the force of connecting the rear side portion 20B to the inner surface of the waistline portion 10 may be overlapped and connected to the outer surface of the waistline portion 10.

Yes

[0056] As the connecting means for the waistline portion 10, a mechanical fastener (surface fastener), an adhesive material, or the like can be suitably used as in the case of connecting the front portion 20F and the rear portion 20 described above. . In the case of a mechanical fastener, a male material is fixed to one of the connecting parts F4 and F3 of the back body B and the rear part 20 B, and the female material to which the male material is entangled and locked is fixed to the other. Can do. By forming the male material locking portion on the other side with a non-woven fabric, this non-woven fabric can be used as a female material.

[0057] When an adhesive is used, it is necessary to select one of the connecting parts F4, F3 of the back body B and the rear part 20B. One of them may be provided with an adhesive layer, and the other may be formed of the material itself, but it is preferable to provide a resin film that adheres so that the adhesive can be peeled off and reattached.

As in the first embodiment, the absorbent main body 20 is formed so as not to be detachable from the waistline portion 10.

[0059] On the other hand, in a general disposable diaper, for the purpose of preventing side leakage, barrier one-force flaws extending in the front-rear direction are provided on both sides in the width direction of the product. It is possible to adopt this. In this case, according to the present invention, the front portion 20F and the rear portion 20B of the absorbent main body 20 are divided, so that these barrier one-force fuzzes are provided in each of the front portion 20F and the rear portion 20B. However, when a general-purpose type barrier single-piece flaw is provided, the front and rear ends of the noir cuff are fixed so that they do not stand up.Therefore, leakage occurs particularly near the boundary between the front part 20F and the rear part 20B. In the easy part, there will be a part where the barrier force hose of the front part 20F and the barrier force hose of the rear part 20B do not stand up. In addition, leakage may occur through the connecting portion of the front portion 20F and the rear portion 20B.

Therefore, more preferably, as shown in FIGS. 33 to 37, the front portion 20F and the rear portion

From the end of the connecting part Fl, F2 on both sides in the width direction to the end of the waste part W side, and on the one side in the width direction at the end of the connecting part Fl, F2 with respect to each inner surface of 20B Noir cuffs 30 and 30 standing on the body side are provided along a U-shaped peripheral area including the end to the other end.

[0061] More specifically, a U-band-shaped barrier sheet 31 having a predetermined width is disposed along the U-shaped peripheral area of each of the front portion 20F and the rear portion 20B. The outer edge portion 31a of the sheet 31 is fixed to the surface of the top sheet 21 by hot melt bonding or the like, and the inner edge side portion 31b is fixed to the surface of the top sheet 21 by hot melt bonding or the like at both ends 33 and 33 on the waist W side. The middle part is not fixed. In addition, the barrier sheet 31 has at least the non-fixed portion and the whole) formed in a double shape, and an elongated elastic elastic member 32 such as a rubber thread is stretched between the double sheets. It is clamped and fixed along the longitudinal direction. A water-repellent nonwoven fabric can be suitably used as the nore sheet 31. In use, the non-fixed portion of the barrier sheet 31 is caused by the contraction force of the elastic elastic member 32. Standing away from the top sheet 21, the portions 30L and 30L along the widthwise sides are in close contact with the wearer's legs, and the connection portion Fl and the portion 30C along the F2 side end are also attached to the wearer's body. In close contact. As a result, the former portions 30L and 30L prevent excrement that moves laterally on the top sheet 21 to prevent lateral leakage, and the latter portion 30C prevents the front portion 20F and the rear portion. Leakage from the connecting parts Fl and F2 of 20B is also prevented.

[0062] FIG. 39 shows a configuration that considers continuous production. More specifically, in each of the front portion 20F and the rear portion 20B, the elastic elastic members 32, 32 on both sides in the width direction are on the connecting portion F1 side in the portion located on the inner surface side (the front portion 20F in the illustrated example). It is arranged so that it is curved so as to be located on the center side in the width direction as it approaches the edge of the, and crosses at the center in the width direction at the edge. When such a curved crossing arrangement is adopted, the elastic stretch members 32, 32 are placed in the width of the CD direction on the barrier sheet material while conveying the material of the barrier sheet 31 with the MD direction as the product longitudinal direction. Supply and arrange while moving back and forth from one end side to the other end side, and further cover the noir sheet material on it, then cut sequentially at the boundary between the front part and the rear part As a result, Norriya cuffs 30, 30 can be continuously produced on the production line.

[0063] In the barrier one-force hose 30 of the form shown in Fig. 39, the portions 30L, 30L along the both sides in the width direction and the portion 30C along the connecting portion side end are integrally formed in a U-shape! / In addition, it is also possible to provide a general-purpose barrier force hose with a linear force S on the portions 30L and 30L along both sides in the width direction and a portion 30C along the end of the connecting portion. In this case, it is preferable to connect the connecting portion side end portion of the barrier sheet forming the portion along both sides in the width direction to the barrier sheet forming the portion along the connecting portion side end portion. This form is also suitable for continuous production on the production line because the barrier one-piece frame is constituted by a combination of linear members.

[0064] On the other hand, as shown in FIGS. 40 and 41, the body side surface of the portion 31C along the end of the coupling portion side of the barrier portion 1 of the front portion 20F and the barrier force of the rear portion 20B. If the connecting means F1 and F2 that connect the body side surface of the part 31C along the connecting part side end of the hose 30 in the shape of a palm are provided, the two are pulled together to maintain a good standing state. I like it. In particular, in this structure, when the portions 30L, 30L along the both sides in the width direction and the portion 30C along the end of the connecting portion are integrally formed in a U-shape, a straight-line general-purpose barrier one-force frame is used. Is applied separately when connecting the two parts 30L, 30L along the both sides in the width direction and the part 30C along the end of the connecting part and connecting them, as shown in Fig. 41, the noir cuff 30 of the front part 20F And the rear part 20B barrier one force hose 30 and the force connecting part 30C along the end of the connecting part side, and pulling each other up to stand up. A part S is formed to prevent side leakage and leakage from the connecting part with force S.

[0065] Unlike the illustrated embodiment, both a mechanical fastener and an adhesive material can be provided as connecting means for each connecting portion. Mechanical fasteners have strong bonding strength (peeling and shearing) but poor sealing performance. On the other hand, the adhesive material has a weak bonding force but has a high sealing property at the bonded portion. Therefore, by providing both, it is possible to ensure the tightness of the connecting portion with the adhesive material while enabling strong connection with the mechanical fastener. From this point of view, such a combination is preferably applied to the connecting portions Fl and F2 between the front portion 20F and the rear portion 20B. Further, it is preferable that the adhesive layer extends continuously over the entire width direction of the connecting portions Fl and F2. Further, as shown in FIG. 5, the adhesive material layer N is provided on the front end side of the connecting portion F1 of the front portion 20F and the connecting portion F2 of the rear portion 20B, which is overlapped on the inner surface side. A mechanical fastener F is preferably provided on the end side.

[0066] In addition, it is preferable that at least one of the front portion 20F and the rear portion 20B, preferably both, is provided with display means for informing excretion. Such a display means can be provided by, for example, applying a composition that changes color due to moisture on the inner surface (side surface of the absorber 22) of the liquid-impermeable sheet 23.

[0067] The other points are the same as in the first embodiment, and therefore, the same reference numerals as those in the first embodiment are used in the drawing, and the description thereof is omitted.

[0068] (Other)

(I) The male and female of the mechanical fastener in the above example (hook tape and non-woven fabric or target tape) are provided oppositely, that is, the male material is provided! /, Where the female material is provided and the female material is provided A male material can be provided.

(Mouth) In the above example, force using a mechanical fastener as the connecting means of the connecting portion may be replaced with other means such as an adhesive layer. When using adhesive material, It is not necessary to provide a pressure-sensitive adhesive layer at one of the connecting portions and the other connecting portion connected thereto, but it is preferable to provide a resin film that adheres so that the pressure-sensitive adhesive can be peeled off and re-adhered. Good. For example, a mode in which an adhesive layer is provided at the connection portion of the waistline portion 10 and a resin film subjected to a peeling treatment is fixed to the outer surface of the absorbent main body 20 is preferable. It is also preferable to use a self-adhesive adhesive that adheres only to the same type of material and does not substantially adhere to other materials.

(C) Contrary to the above example, the front end portion of the absorbent main body 20 is fixed to the inner surface of the intermediate portion 10c of the waistline portion 10 by hot-melt bonding or the like, and the waistline around the outer surface of the rear portion of the absorbent body 20 The parts can also be configured to be detachably connected.

(2) During manufacture of the waistline portion 10, in order to improve the material yield by so-called trimless, as shown in FIG. It is also preferable that each projecting portion 18a and a portion 18b between adjacent projecting portions 18a are configured to be point-symmetric while projecting. As a result, as shown in the figure, it can be manufactured by a so-called trimless. Specifically, a main body sheet raw fabric 130 that is double the width of the waistline portion 10 and continuous in the longitudinal direction of the product is manufactured in advance, and this main body sheet original fabric 130 is fed out and the hook tape 15 is continuously bonded to the center position. If this is the case, the hook tape 15 is cut along the wavy periodic curve 19a alternately traversing in the CD direction and continuing in the MD direction, and a cutting line 19b for dividing each waist part 10 is inserted, and each waist part 10 Make a perforation 16 in place every time.
