The paper diaper of this embodiment has the middle part 10c and the side flap parts 11 and 12 which protruded to both sides, respectively, The strip | belt-shaped trunk circumference 10 and the rear end which wind around the torso of a wearer are the trunk | drum It is comprised by the absorbent main body 20 etc. which are connected to the intermediate part 10c of the circumference part 10, and are mounted so that it may pass through the groin part from the back side, and to cover it to a stomach.

The absorbent body 20 is formed along the center of the width direction of the product to cover the abdomen, groin and buttocks of the wearer to form a rectangle with the longitudinal direction of the product in the longitudinal direction, the rear end portion 20B of the body by hot melt bonding, etc. It is fixed to the inner surface of the intermediate part 10c of the circumference 10 so that attachment or detachment is impossible.

In addition, as will be described later, the rear end portion 20B of the absorbent body 20 may be detachably connected to the inner surface of the middle portion 10c of the trunk circumference 10 using an adhesive tape, a target tape, or the like. It is preferable to use a method of separating only the absorbent main body 20 soiled at the time of diaper replacement and mounting the new absorbent main body 20.

The absorbent body 20 receives the excrement to absorb and maintain the liquid component. As shown in FIGS. 3 to 5, the liquid permeable top sheet 21 and the liquid impermeable sheet 23 forming a use surface in contact with the body are illustrated. And the absorbent body 22 interposed therebetween, and have a structure in which the top sheet 21 and the liquid impermeable sheet 23 are joined by hot melt bonding or the like in the peripheral portion.

Moreover, the flap forming member which is smaller than the trunk | drum circumference 10 and does not have elasticity in the edge part of the absorptive main body 20 which opposes the edge part to which the trunk circumference 10 was attached can also be attached. Thus, it is preferable to provide a small flap at both sides of the opposite side of the absorbent body end of the trunk circumference 10 so that it can be used as a handle of the connecting portion at the time of positioning between the connecting portions when fixedly mounted.

The top sheet 21 can be formed of a nonwoven fabric, a film having a liquid through hole, a net sheet, or the like, and the liquid impermeable sheet 23 can be formed of a plastic sheet such as a polyethylene sheet. On the outer surface of the liquid impermeable sheet 23, an outer nonwoven fabric 24 such as a water repellent nonwoven fabric is attached, and in the illustrated form, the outer nonwoven fabric 24 becomes a connection portion of the trunk circumference 10. It is preferable that the exterior nonwoven fabric 24 has a weight of 15-50 g / m <^2> from a viewpoint of exhibiting sufficient binding force, and, as a kind, an air through nonwoven fabric, a point bond nonwoven fabric, a span bond nonwoven fabric, SMS nonwoven fabric, etc. are preferable. In this case, it is possible to reinforce by embossing at least the connecting portion (for example, the front side portion, or the whole portion from the center in the front-rear direction, etc.) of the exterior nonwoven fabric 24. In the figure, reference numeral 25 denotes a recess by embossing. The embossing is made to be pressed by the convex emboss roll on the exterior nonwoven fabric 24 side after attaching the exterior nonwoven fabric 24 and the liquid impermeable sheet 23. The roll facing the convex emboss roll may be a concave emboss roll having a concave portion corresponding to the convex portion of the convex emboss roll, or may be a rubber roll having a flexibility such that the convex portion of the convex emboss roll is pressed in. Do not. The embossed area of the adhesive point area of the convex portion of the convex emboss roll is 5 to 50%, preferably 5 to 40%, more preferably 10 to 30%. If the embossed area is less than 5%, the adhesive force is insufficient, and if the embossed area is larger than 50%, the sheet obtained by embossing may be hardened and the softness may be damaged. The pattern of the embossing provided as a connection part can select arbitrary patterns, such as a dot shape, a zigzag shape, a grid | lattice form, and linear.

It is also possible to provide a target tape 26 having a plurality of loops hooked on the inner surface of the sheet and to use it as a connecting portion, regardless of whether or not the sheath is made of a nonwoven fabric. Although the target tape 26 is preferably provided in a part such as a front part of the center in the front-rear direction, for example, it may be provided throughout.

As the absorber 22, in addition to integrating short fibers such as cotton pulp, a filament aggregate may be used. The filament aggregate can be formed by opening the tow (fiber bundle) such as cellulose acetate. The absorbent body 22 may contain a super absorbent polymer (SAP) as needed, or may be wrapped with crepe paper, nonwoven fabric, or the like.

In addition, barrier cuffs 30 and 30 standing up against the top sheet 21 at the time of mounting are provided in the width direction both sides of the absorbent main body 20, respectively. In more detail, the edge 31a of the width direction outer side of the barrier sheet 31 which forms the strip | belt shape over the whole longitudinal direction in the both sides of the absorptive main body 20 is the surface of the top sheet 21 by hot melt adhesion etc. The portion 31b on the central side in the width direction is fixed to the top sheet 21 surface by hot melt bonding at the front and rear ends of the absorbent body 20, but not at the middle portion in the longitudinal direction. In addition, the non-fixed portion 31b has a double structure by folding the tip side portion and attaching it to the rear end side portion, and the elongated elastic elastic member 32 such as a rubber band is elongated between the sheets of the double structure portion. It is fitted along the direction and fixed. In use, the non-fixed portion 31b of the barrier sheet 31 stands up so as to be spaced apart from the top sheet 21 by the elastic force of the elastic elastic member 32, and its tip portion is in close contact with the leg of the wearer. As a result, the excrement moving laterally along the top sheet 21 is blocked and side leakage is prevented. As the barrier sheet 31, a water repellent nonwoven fabric can be preferably used.

The trunk circumference 10 is a strip-shaped member corresponding to a portion from the waist opening through which the body of the wearer passes, and the leg opening through which the leg of the wearer passes. The trunk circumferential portion 10 has an absorbent body 20 and a corresponding intermediate portion 10c in the product width direction and first and second side flap portions 11 and 12 protruding on both sides thereof, and each side flap. The wrap portions 11 and 12 have elastic portions 11x and 12x on the rear end side and connecting portions 11f and 12f on the front end side. The elastic parts 11x and 12x are the parts which generate | occur | produce elasticity of a trunk circumferential direction in both sides of a product, and the connection parts 11 and 12f are the parts connected when assembled in panties.

More specifically, as can be seen from each of the cross-sectional views of FIGS. 6 to 9, the trunk circumference 10 is based on the body sheet 13 throughout the entire body, and the function is imparted to each part by the addition of the member. . More specifically, the main body sheet 13 is a plurality of nonwoven fabrics 13a and 13b overlapped with each other and fixed by hot melt adhesive or the like, and between the nonwoven fabrics 13a and 13b, an intermediate portion 10c and an elastic portion of the circumference of the body The elastic stretchable member 14 is fitted and fixed in the stretched state along the width direction over 11x and 12x.

In particular, in the waist circumference of the illustrated form, in the waist portion W defined as a vertical range from the upper edge (the edge of the waist opening) to the vicinity of the upper end of the absorbent body 20, the middle circumference 10c of the trunk circumference is defined. And the elastic elastic member 14 in the lower portion U defined as the lower portion than the waist portion W, while the elastic elastic member 14 is continuously provided throughout the trunk circumferential direction of the elastic portions 11x and 12x. ) Is provided so that the elastic force acts only on both sides thereof except for the intermediate portion 10c in the width direction overlapping with the absorbent body 20. In the form in which the elastic force acts only on both sides, in addition to the form in which the elastic elastic members 14 exist only on both sides, the entire body circumferential direction of the middle portion 10c and the elastic portions 11x and 12x of the trunk circumference 10 is present. The elastic elastic member 14 is present over the middle portion 10c, but the elastic elastic member 14 is cut off, and the elastic elastic member 14 is also configured to prevent the elastic force from working. In addition, the arrangement | positioning area | region of the elastic stretchable member 14 does not need to exactly match the outline of the absorbent main body 20, and if it is near, the elastic stretchable member 14 may overlap with the absorbent main body 20, or may be separated.

As the elastic stretching member 14, a band-like material of a rubber band or an elastic foam, a film-shaped elastic body, a net-shaped elastic body, etc. may be used, but it is preferable to provide a plurality of rubber bands in parallel along the trunk circumferential direction. Specifically, a thickness of 300 to 1200 dtex, preferably 400 to 1000 dtex, is about 5 to 7 rubber bands at intervals of 4 to 6 mm on the waist portion W, and 10 to 3 to 8 mm intervals on the lower portion U. About 30 pieces, each 150-400% elongation rate, It is preferable to fix about 200-300% each.

In each connection part 11f, 12f of the 1st and 2nd side flap parts 11 and 12, the hook in which many hook-like protrusions, such as mushroom shape and a J-shape, are arranged in the inner surface of the main body sheet 13 on the surface The tape (mailing member of the mechanical fastener) 15 is attached to the whole of the up and down direction by hot melt bonding or the like.

And characteristically, in each side flap part 11 and 12, the cutout line 16 extended from the up-down middle of the front-end | tip edge to the middle part 10c side along the width direction is formed. The cutout line 16 may extend to the boundary with the intermediate portion 10c, but as shown in the example, up to the middle in the width direction of the stretchable portions 11x and 12x, specifically from 1/3 to 1/2 from the tip edge side. It is preferable to extend to the range of. In addition, the up-down position of the cutting line 16 is a center in the up-down direction in the illustrated example, but is not limited thereto. For example, the cutting line 16 may be formed along a boundary between the waste portion W and the lower portion U.

In addition, in this embodiment, although the form of the perforation line 16 of one line is demonstrated, the form which has a several perforation line 16 is not excluded at all, and in the case of the form which has the several perforation line 16, size adjustment is more freely. This becomes possible. In the case where a plurality of perforation lines are provided, all of the perforation lines of the plurality of perforations (the width of the perforation line, the perforation line pitch, etc.) may be the same perforation lines, or may be different perforation lines.

In one preferred form, the stretch stress in the product width direction of the portion corresponding to the upper side of the cut line 16 and the stretch stress in the product width direction of the portion corresponding to the lower side of the cut line are different from each other when the cut line 16 is separated. It is also proposed to configure. For example, the stretching stress in the product width direction of the portion corresponding to the upper side of the tear line 16 can be made larger than the portion corresponding to the lower side of the tear line 16. More specifically, the product width direction elastic stress of the part corresponding to the upper side of the cut line 16 can be made about 1.5-2.5 times the product width direction elastic stress of the part corresponding to the lower side of the cut line 16. FIG. In addition, the definition of the stretching stress is as described above. What is necessary is just to differ in the number, thickness, elongation rate, etc. of elastic elastic members in the upper side and the lower side of the cutout line 16, in order to give a magnitude | size to an elastic stress.

In addition, in this embodiment, the lower edge part of each side flap part 11 and 12 is curved so that the direction may change gradually to the groin side as it approaches the absorbent main body 20 in the vicinity of the absorbent main body 20. As shown in FIG. As a result, the vicinity of the intersection between the lower edges of the side flap portions 11 and 12 and the side edges of the absorbent body 20 fits around the leg of the wearer. In addition, along the curved portions of the side flap portions 11 and 12, an elongated elastic elastic member 17 such as a rubber band is fixed in an elongated state and the top sheet at both sides of the absorbent body 20 ( 21) and the liquid impervious sheet 23 at a position intersecting with the front body portion of the torso circumference 10, in the form shown at least in the front and rear direction, at least the edge forming the edge of the leg opening LO. An elongate elastic member 27, such as a rubber band, is secured in an elongated state to a portion up to the intersection with the rear body plate portion of the trunk circumference 10. As a result, the entire edge portion of the leg opening LO is stretched in the leg circumferential direction.

On the other hand, the paper diaper which can be used as a panty type or a fixed type configured in this way can be assembled as follows, as well as how to connect each part to fit the body in the unfolded state, as well as how to wear it by passing both legs to a previously formed panty type. It is possible.

That is, in the use of the former, the width direction center of the absorbent body 20 at the circumference of the body is aligned with the left and right centers of the dorsal recess, and then the front side of the absorbent body 20 is first shown as shown in FIG. Bring it to the stomach and then take the first side flap portion 11 and the second side flap portion 12, as shown in Figs. 11 and 12, and attach the inner mail members 15 and 16 to the outer surface of the absorbent body 20. Engage the jam. As a result, the trunk circumference 10 is wound around the trunk, and the absorbent body 20 is covered with the groin section and both front and rear sides thereof to complete the mounting.

The same applies to the usage of forming the panties in advance.

&Lt; Third Embodiment >

Fig. 33 shows the paper diaper of the third embodiment, and is characterized in that the absorbent body 20 is constituted from the front part 20F located in the front-back direction and the rear part 20B located in the back. Each of the front side portion 20F and the rear side portion 20B is a liquid permeable top sheet 21 and a liquid impermeable sheet 23 and a liquid permeable top sheet 21 forming a use surface in contact with the body, as also shown in FIGS. 34 to 36. It consists of the absorber 22 interposed in between. The outer surface of the liquid impermeable sheet 23 can be bonded to the same outer nonwoven fabric as in the first embodiment.

In addition, the rear end portion F1 of the front side portion 20F and the front end portion F2 of the rear side portion 20B can be attached and detached by connecting means, as can also be seen from FIGS. 36, 37 and 38. Is connected. The connecting means may be appropriately selected, but a mechanical fastener (face fastener), an adhesive or the like is preferable from the viewpoint of ease of manufacture. In the case of a mechanical fastener, a mail member having a plurality of hooks, such as mushrooms or J-shapes, is arranged on the connection part F1 on one side of the sheet surface, and a female member in which the mail member is entangled and engaged is connected to the other side. It can provide in (F2). As the female member, one having a plurality of loops formed on the entire sheet surface can be used. The nonwoven fabric can also be used as a female member by forming the connecting portion F2 to which the mail member is engaged by a nonwoven fabric. The mail member and the female member of the mechanical fastener can be adhesively fixed to the front part 20F or the rear part 20B by a hot melt adhesive or the like.

In the case of using the adhesive material, an adhesive material layer may be provided on any one of the connecting portions F1 and F2 of the front portion 20F and the rear portion 20B, and the connecting portion on the other side may be formed by the material itself, but the adhesive may be peeled off and It is preferable to provide the resin film to stick so that re-adhesion is possible. The resin film can be adhesively fixed to the front part 20F or the rear part 20B by a hot melt adhesive or the like.

Although the connection position of the front part 20F and the rear part 20B can be suitably determined, it is preferable that it is located in the groin part CR. The crotch part CR in a product is not collectively, but is determined by the center part of the front-back direction of the normal product, and its vicinity. Specific connection positions may be arranged to be included in the central area when the product is divided into three in the longitudinal direction.

In the illustrated embodiment, the outer side of the rear side 20B and the inner side of the front side 20F are overlapped and joined to each other with the rear side 20B as the inner side and the front side 20F as the outside. It is also possible to configure the connection in the ensemble state. When the front portion 20F and the rear portion 20B are overlapped as shown in the figure, the absorber 12 of the front portion 20F and the absorber 12 of the rear portion 20B are not overlapped to neatly connect the connecting portions. Although not preferable, it may be configured to overlap to some extent, for example, about 1 to 5 cm in order to improve the absorbency of the groin CR.

In addition, in the case of the paper diaper of the third embodiment, as shown in FIGS. 35 and 38, the rear side portion 20B has a lower end portion F4 at the center portion in the width direction of the inner surface of the trunk circumference 10 at the outer surface upper end portion F3. ) Is detachably connected. In the illustrated example, the rear portion 20B is connected to the inner surface of the trunk circumference 10, but may be connected to the outer surface of the trunk circumference 10.

As the connecting means for the trunk circumference 10, mechanical fasteners (surface fasteners), adhesives and the like can be suitably used as in the case of the connection between the front part 20F and the rear part 20B. In the case of mechanical fasteners, the mail member can be fixed to one side of each of the connecting portions F4 and F3 of the rear body plate B and the rear part 20B, and the female member to which the mail member is entangled and engaged can be fixed to the other side. have. The nonwoven fabric can also be used as a female member by forming the engaging portion on the other side by a nonwoven fabric.

In the case of using the adhesive material, an adhesive material layer may be provided on any one of the connecting portions F4 and F3 of the rear body plate B and the rear part 20B, and the other side may be formed by itself on the material, It is preferable to provide the resin film to adhere | attach so that adhesion is possible.

As in the first embodiment, it is also possible to form the absorbent body 20 in a non-removable manner with respect to the trunk circumference 10.

On the other hand, in general paper diapers, barrier cuffs extending along the front-back direction are provided on both sides in the width direction of the product for the purpose of preventing side leakage, but the third embodiment can also be adopted. In this case, since the front part 20F and the rear part 20B of the absorbent main body 20 are divided, these barrier cuffs are provided in each of the front part 20F and the rear part 20B. However, in the case where the general-purpose barrier cuff is simply provided, the front and rear ends of the barrier cuff are fixed so as not to stand, so that the front side is near the boundary between the front part 20F and the rear part 20B, that is, in a region where leakage is likely to occur. There is a portion where the barrier cuff of the portion 20F and the barrier cuff of the rear portion 20B do not stand. In addition, there is a fear that leakage occurs through the connection portion between the front portion 20F and the rear portion 20B.

Therefore, more preferably, the waste portion at the end portions of the connecting portions F1 and F2 on both sides in the width direction with respect to the inner surfaces of each of the front portion 20F and the rear portion 20B, as shown in FIGS. 33 to 37. Barrier cuffs standing on the body side along the U-shaped edge circumference range including the end portion on one side in the width direction of the end portion on the side of the connection portion F1 and F2 and the other end portion up to the end portion on the (W) side. , 30).

More specifically, a U-shaped barrier sheet 31 having a predetermined width is disposed along the U-shaped edge circumferential range in each of the front portion 20F and the rear portion 20B. ) Is fixed to the top sheet 21 surface by hot melt bonding, and the inner edge portion 31 b is formed by hot melt bonding at both ends 33 and 33 on the waist portion W side. 21) It is fixed on the surface but not in the middle part. In addition, at least the non-fixed portion (or the entirety) of the barrier sheet 31 is formed in two, and between the two sheets, an elongated elastic member 32, such as a rubber band, is inserted and fixed along the longitudinal direction in an extended state. It is. As the barrier sheet 31, a water repellent nonwoven fabric can be preferably used. In use, the unfixed portion of the barrier sheet 31 stands up so as to be spaced apart from the top sheet 21 by the contracting force of the elastic elastic member 32, and the portions 30L and 30L formed along both sides in the width direction are formed around the leg of the wearer. Part 30C which is in close contact with each other and formed along the connecting end portions F1 and F2 is also in close contact with the wearer's body. As a result, the excrement which moves laterally on the top sheet 21 by the former part 30L, 30L is prevented, and a side gland is prevented, and the front part 20F and the rear part ( Leaking through the connecting portions F1 and F2 of 20B is also prevented.

39 shows a form in consideration of continuous manufacturing. More specifically, in each of the front portion 20F and the rear portion 20B, the elastic elastic members 32 and 32 on both sides in the width direction are located on the inner surface side (in the illustrated example, the front portion 20F). As it approaches the edge of the side of the connection part F1 in the side, it curves so that it may be located in the width direction center side, and is arrange | positioned so that it may cross in the width direction center at the edge. By adopting such a curved crossover arrangement, the elastic stretching members 32 and 32 are placed on the barrier sheet material at one end in the width direction of the CD direction while the line material of the barrier sheet 31 is line-transferred with the front and rear direction of the product as the MD direction. The barrier cuffs 30 and 30 can be continuously manufactured in the production line by supplying and arranging with reciprocating oscillation to the end side, and covering the barrier sheet material thereon and then sequentially cutting at the boundary between the front part and the rear part.

In the barrier cuff 30 of the type shown in FIG. 39, the portions 30L and 30L positioned along both widthwise side portions and the portion 30C positioned along the connection portion side end portions are integrally formed in a U-shape, but are linear and general. It is also possible to separately provide the barrier cuffs into portions 30L and 30L positioned along both widthwise sides and portions 30C positioned along the connecting portion side ends. In this case, it is preferable to connect the connection part side edge part of the barrier sheet which forms the part located along the width direction both sides to the barrier sheet which forms the part located along the connection part side end part. This form is also suitable for continuous production in a manufacturing line because the barrier cuff is formed by a combination of linear members.

On the other hand, as shown in FIG. 40 and FIG. 41, the barrier cuff of the body side of the part 31C located along the connection part side edge part in the barrier cuff 30 of the front part 20F, and the rear part 20B. Providing the connecting means (F1, F2) for connecting the body side surface of the portion 31C positioned along the connecting portion side end portion in the assembled state in (30), both of them pull each other to maintain a good standing state It is preferable because of that. Particularly, when the structure is integrally formed with U-shaped portions 30L and 30L located along the widthwise both sides and the portion 30C located along the connecting portion side end portions, a linear universal barrier cuff is also provided on both sides in the widthwise direction. The barrier cuff of the front part 20F is separately provided as the part 30L and 30L located along the part, and the part 30C located along the connection part side end, and when applied to both of them, as shown in FIG. 30) and the barrier cuff 30 of the rear portion 20B are integrated through the portion 30C positioned along the connecting portion side end, and pull each other to stand, so that the standing H-shaped standing portion is formed when viewed in plan view. The leaks can be reliably prevented through the and connections.

In addition, unlike the illustrated form, a mechanical fastener and a pressure-sensitive adhesive may be provided together as a connecting means of each connection part. Mechanical fasteners have strong bonding (peel and shear) but poor sealing. The adhesive material has a weak bonding strength but a high sealing property at the joint portion. Therefore, by using both together, the sealing property of a connection part can be ensured by an adhesive material, enabling a strong connection by a mechanical fastener. From this point of view, this combination is preferably applied to the connecting portions F1 and F2 of the front portion 20F and the rear portion 20B. Moreover, it is preferable that the adhesive material layer extends continuously throughout the width direction of the connection parts F1 and F2. In addition, as shown in FIG. 5, the pressure-sensitive adhesive layer N is provided at the front end side of the connecting portion F1 of the front side portion 20F and the connecting portion F2 of the rear side portion 20B on the inner side of the side and is rear-end. It is preferable that a mechanical fastener F is provided in the side.

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