Absorbent articles such as paper diapers absorb urine discharged from the wearer by an absorbent using an absorbent component such as wood pulp, super absorbent polymer (hereinafter also referred to as “SAP”), and It is an article that accepts stool (stool).
Conventional absorbent articles are provided with pleated members called inner gathers or outer gathers that can be expanded and contracted by inserting rubber on the left and right sides of the portion that absorbs urine and receives stool. The structure prevents leakage of urine and feces to the outside.

However, in such an absorbent article, the central part expands when worn, and the distance between the left and right inner gathers or outer gathers is about 70 to 80 mm for children and about 100 to 150 mm for adults. Since the entire lower body is encased, there is a problem that when the urine is discharged, the entire lower body gets wet, and when the stool is discharged, the wearer's buttocks tend to get dirty from the entire lower body.
In addition, since the conventional inner gathers or outer gathers are stretchable and can extend in the front / rear and left / right directions, depending on the position and movement of the wearer, there is a gap between the absorbent article and the wearer's body during or after the discharge. There is also a problem that urine and feces may leak to the outside through the gap.

As the material of the first leak preventer 10, a material generally used as a back sheet can be used. Specifically, for example, a resin film such as PE, PP, PET, and EVA; and a body fluid impermeable sheet such as a foamed sheet of the resin can be used. As the body fluid impermeable sheet, a material having air permeability such as an air permeable film is also preferably used.
Moreover, when using the film of the said resin, in order to improve a touch and an external appearance, it can also be used as a multilayer sheet | seat of a film and a nonwoven fabric. In this case, as the nonwoven fabric, SB, SMS, thermal bond nonwoven fabric and the like having a relatively low basis weight are preferably used.
Also, a multilayer sheet of the resin film and a sheet-like absorber described later can be used.
A highly water-resistant nonwoven fabric can also be used. In this case, you may use independently and can also be used as a multilayer sheet | seat of a film and a highly water-resistant nonwoven fabric.

  The first leak preventer 10 may be composed of a plurality of members.

As described above, the first leak preventer 10 includes the bottom surface portion 12 and the pair of side portions 14. In FIG. 1, the pair of side portions 14 are bent at an acute angle from the bottom surface portion 12, but are not particularly limited as long as the rising edges are bent inward from the left and right sides of the bottom surface portion 12.
An inner space S is formed by the bottom surface portion 12 and the pair of side portions 14. In the internal space S, the absorber 20 is arranged.

The absorbent body 20 used in the present invention is not particularly limited as long as it contains a highly water-absorbent resin and can absorb body fluids. For example, powdered absorbent bodies such as powdered wood pulp and unprocessed SAP However, a sheet-like absorbent body is preferable in consideration of form stability, possibility of dropping off, and the like. Especially, the sheet-like absorber formed by coating the said highly water-absorbent resin on a nonwoven fabric is preferable.
The kind of absorber can be suitably selected according to a use. For example, when the absorbent article of the present invention is used as a diaper for children, as a product for newborns or infants with a low age (in terms of size, S size), a material having a high content of wood pulp is preferable. For infants with a high age (in terms of size, M size or L size), those having a high SAP content are preferred.

Among the sheet-like absorbent bodies, one preferred embodiment is a superabsorbent sheet containing SAP of 50% by mass or more, preferably 60 to 95% by mass.
The highly water-absorbent sheet is an ultrathin sheet-like absorbent body mainly composed of SAP. The superabsorbent sheet has a very small thickness because the SAP content is extremely high. The thickness of the superabsorbent sheet is preferably 1.5 mm or less, and more preferably 1 mm or less.
As long as the superabsorbent sheet is an ultra-thin sheet-like absorbent body mainly composed of SAP, the configuration and the production method are not particularly limited.
For example, a super absorbent sheet obtained by the Air Laid method can be mentioned. The Air Laid method is a method in which pulverized wood pulp and SAP are mixed, a binder is added, and the resultant is formed into a sheet shape to obtain a highly water-absorbent sheet. As a highly water-absorbent sheet obtained by this method, for example, NOVATHIN (registered trademark) manufactured by Rayonier in the United States and B-SAP manufactured by Oji Kinocross are known.
Moreover, the superabsorbent sheet obtained by the method of coating SAP dispersion | distribution slurry on body fluid permeable sheets, such as a nonwoven fabric, is also mentioned. Here, it is preferable that the SAP dispersion slurry is obtained by dispersing SAP and microfibrillated cellulose (MFC) in a mixed solvent of water and ethanol. As a highly water-absorbent sheet obtained by this method, MegaThin (registered trademark) manufactured by Japan Absorbent Technology Laboratory is known, for example.
In addition, for example, a superabsorbent sheet obtained by a method in which a large amount of SAP is supported on a brushed nonwoven fabric and fixed with a hot melt binder, an emulsion binder, an aqueous fiber, etc., and fibrous SAP is mixed with PET (polyethylene terephthalate) fiber And a superabsorbent sheet obtained by a method of forming a web, and a SAP sheet in which the top and bottom of the SAP layer are sandwiched between tissues.

At least one layer of the absorber is arranged. That is, the absorber may be a single layer or two or more layers (multiple layers).
The absorber can also be arranged in a folded state.

In FIG. 1, the edge shape holding member 30 is provided along the entire length of the edge, but in the present invention, the edge shape holding member 30 is not particularly limited thereto. The holding member may not be provided.

The edge shape holding member 30 has a function of holding the shape of the edge part of the side part and closely attaching the edge part to the wearer's body. This effectively prevents urine and feces from leaking outside the first leak preventer 10. In addition, it is possible to prevent uneven and large irregularities from occurring on the side portion when worn.
The material of the edge shape holding member 30 preferably has cushioning properties (elasticity) and a certain thickness. For example, a foam (for example, PU, PP, made by PP / EVA), a synthetic rubber sheet, a stretchable elastic film, a rubber filament, and a polyurethane filament are preferably exemplified. Also, cushioning and a certain thickness can be achieved by forming a gather with rubber thread and turning it back.

Furthermore, a bridging member 40 is provided between the central portions of the pair of edge shape holding members 30.
The bridging member 40 has a function of keeping the distance constant by connecting between the pair of edge shape holding members 30. As a result, there is less room to extend left and right like conventional inner gathers or outer gathers so that the bottom surface portion 12 of the first leak preventer 10 and the body surface of the wearer can contact only a relatively narrow range. Therefore, the lower body due to urine discharge, particularly the front part thereof, is less wet, and the buttocks are less likely to become dirty due to fecal discharge.
In order to obtain such an effect, it is preferable to appropriately define the distance L ₁ between the pair of edge shape holding members 30. For example, in the case of men, the distance is preferably such that the penis and the testicle are accommodated in the internal space S. For women, it is preferable to set the distance so that the large labia are accommodated in the internal space S. In any case, it is preferable that there is little remainder in the left-right direction of the internal space S.

  The material of the bridging member 40 is not particularly limited as long as it can maintain a certain degree of the shape of the absorbent article in the left-right direction. For example, foams such as PE, PP, and polyurethane, and those coated with a fiber bundle such as a slicer and a hydrophobic nonwoven fabric are preferable. The bridging member 40 is preferably thick enough to exhibit cushioning properties.

The length L ₂ in the front-rear direction of the bridging member 40 is not particularly limited for male use, but is 10 to 70 mm for female use because it needs to be shorter than the distance between the wearer's urethral orifice and anus. Is preferred. For children, it is preferably 5 to 40 mm.

And the rear stool storage space S _2, and the absorber 20 a is disposed in the urine absorption space S ₁ .
Examples of the bonding member 50 include an adhesive, rubber, film, foam (foam), and bulky nonwoven fabric.
By separating the internal space S into the urine absorption space S ₁ and the stool storage space S ₂ as described above, the urine / feces separation process can be performed. As a result, it is possible to eliminate problems such as mixing of urine and feces, increasing the odor and facilitating rash. The separation between the urine absorption space S ₁ and the stool storage space S ₂ is preferably complete as in the embodiment shown in FIG. 4, but even if the two are connected, the portion is small. Alternatively, if an absorber that does not easily diffuse urine is used, urine / feces separation processing can be substantially performed.

In this case, it is one of the preferred embodiments that the stool storage space is provided with a sheet-like second leak preventer.
FIG. 5 is a schematic diagram illustrating an example of an absorbent article having a second leak preventer. 5A is a plan view, and FIG. 5B is a vertical end view taken along the line VB-VB in FIG. 5A.
Absorbent article 100h shown in FIG. 5, is basically the same as the absorbent article 100 g, differs in that it has a second leak preventer 60 sheet stool accommodating space S _2. In this case, feces can be accommodated on the second leak preventer 60.

Moreover, the absorbent article 100h shown in FIG. 5 has a urine stop member 42 and a stool stop member 44 at the front and rear ends of the upper surface of the bridging member 40g. The urine stop member 42 prevents the urine discharged into the urine absorption space S _{1 from} moving to the stool storage space S ₂ , and the stool stop member 44 includes the stool discharged into the stool storage space S _2. but, to prevent the move to the space S ₁ for urine absorption. By the urine stop member 42 and the stool stop member 44, the urine / feces separation process is more effectively performed.
In the embodiment shown in FIG. 5, the second leak preventer is planar, but the shape of the second leak preventer is not particularly limited. For example, the length and position in the front-rear direction and the length in the left-right direction are not particularly limited. Specifically, the shape which is the container shape which the edge part has lifted to the upper side is mentioned suitably. In this case, the stool is easily accommodated on the second leak preventer.

Moreover, it is one of the preferable aspects that the absorber is further arrange | positioned between the 1st leak preventer and the 2nd leak preventer in the space for stool accommodation.
FIG. 6 is a schematic diagram illustrating another example of an absorbent article having a second leak preventer. 6A is a plan view, and FIG. 6B is a vertical end view taken along the line VIB-VIB in FIG. 6A.
Absorbent article 100i shown in FIG. 6, is basically the same as the absorbent article 100h, the feces receiving space S _2, between the first leak preventer 10g and the second leak preventer 60, Absorber 20b is arranged. In this case, basically, when the stool is soft stool while the stool is accommodated on the second leak preventer 60, the moisture can be absorbed by the absorber 20b, so that the stool (soft stool) leaks outside.

FIG. 7 is a schematic diagram illustrating an example of an absorbent article having a urine introduction part forming member. 7A is a plan view, FIG. 7B is a vertical end view taken along the line VIIB-VIIB in FIG. 7A, and FIG. 7C is a view in FIG. 7A. It is a lateral end view along the VIIC-VIIC line.
In the absorbent article 100j shown in FIG. 7, the front end portion of the second leak preventer 60a is coupled to the lower surface of the bridging member 40, and the urine introduction portion forming member is formed on the lower surface of the front end portion of the second leak preventer 60a. 70 is provided, the absorber 20c is present throughout the lower side of the second leak preventer 60a from the space S ₁ for urine absorption of feces receiving space S _2.

  The urine introduction part forming member 70 is preferably coupled to the second leak preventer 60a, and may or may not be coupled to the absorber 20c.

  The urine introduction part forming member 70 needs a certain thickness in order to secure a gap between the second leak preventer 60a and the absorber 20c, but is not particularly limited otherwise. Examples of the material of the urine introduction part forming member 70 include an adhesive, rubber, a film, a foam (foam), and a bulky nonwoven fabric. In the case of an adhesive, it is applied so as to have a certain thickness. Further, in the case of rubber, film, foam, or bulky nonwoven fabric, it is preferable that the surface and the surface of the second leak preventer 60a are bonded together by an adhesive or the like as a strip or strip.

The urine introduction part forming member 70 is a second leak preventer made of urethane foam blocks having a length (length in the front-rear direction) of 10 mm, a width (length in the left-right direction) of 20 mm, and a thickness of 3 mm with a hot melt adhesive. It is arranged and fixed between the lower surface of the front end portion of 60a and the upper surface of the absorber 20c.
In the absorbent article 100j, urine moves to the rear part of the absorbent body 20c through both sides of the urine introduction part forming member 70 as shown by arrows in FIG. This is because the urethane foam used for the urine introduction part forming member 70 does not have liquid permeability. In this way, by restricting the flow path of urine to some extent, a large amount of urine is concentrated and flows in a specific location, so that urine can easily move to the rear part of the absorber 20c. Therefore, the absorber 20c can be used effectively.

Moreover, in the absorbent article of the present invention, the absorbent body extends from the front side to the rear side of the internal space, and the bridging member is bonded to the absorbent body and the pair of side portions so that the internal space is the front side. It is also a preferred embodiment that the urine absorption space and the rear stool storage space are separated.
FIG. 8 is a schematic view showing another example of the absorbent article of the present invention. 8A is a plan view, FIG. 8B is a vertical end view along line VIIIB-VIIIB in FIG. 8A, and FIG. 8C is in FIG. 8A. It is a lateral end view along line VIIIC-VIIIC.
In the absorbent article 100k shown in FIG. 8, the absorbent body 20c extends from the front side to the rear side of the internal space S, and the bridging member 40g passes through the absorbent body 20c, the pair of side portions 14d, and the coupling member 50a. Thus, the internal space S is separated into a front urine absorption space S ₁ and a rear stool storage space S ₂ .
The embodiment shown in FIG. 8 can be combined with the structures in FIGS. 5 to 7 described above.

Moreover, in the absorbent article of the present invention, it is one of preferred embodiments that the absorbent body is disposed so as to be separated from the left and right.
FIG. 9 is a schematic view showing another example of the absorbent article of the present invention. 9A is a lateral end view before wearing, FIG. 9B is a lateral end view during wearing, and FIG. 9C is a lateral end view immediately after urine discharge.
The absorbent article 100l shown in FIG. 9 is basically the same as the absorbent article 100, but differs in that the absorbent body 20d is spaced apart from the left and right. Thereby, the following effects are acquired.
First, deformation at the center in the left-right direction is facilitated (see FIG. 9B). For this reason, it becomes easy for the wearer to wear the absorbent article at an appropriate position.
Second, due to the above deformation, urine discharged to the central portion easily moves to the left and right and the rear side, and is thus easily absorbed by the absorber.
Third, since there is no absorber in the wearer's crotch, the wearer does not feel uncomfortable at the crotch, especially after absorbing urine.
Fourth, since there is no absorber in the wearer's crotch, problems such as rashes and stuffiness are less likely to occur.
Fifthly, as shown in FIG. 9C, since there is no absorber in the central part in the left-right direction, immediately after urine discharge, the discharged urine u is temporarily stored in the central part, Since it can be gradually absorbed by the left and right absorbers (see arrows in the figure), even when a large amount of urine is excreted in a short time, urine can be efficiently absorbed. .

Furthermore, it is preferable that the liquid guide sheet is disposed between the absorbent bodies that are spaced apart from each other on the left and right.
FIG. 10 is a schematic diagram illustrating an example of an absorbent article having a liquid guide sheet. FIG. 10 (A) is a lateral end view before wearing, and FIG. 10 (B) is a lateral end view during wearing.
The absorbent article 100m shown in FIG. 10 is basically the same as the absorbent article 100l, but the liquid guide sheet 80 is disposed between the absorbent bodies that are spaced apart from each other on the left and right. .
The liquid guide sheet 80 has a flow path for moving urine. The urine discharged from the wearer's urethral orifice to the central portion in the left-right direction of the first leak preventer passes through the flow path of the liquid guide sheet 80 and quickly moves to the absorber 20d. Therefore, the wearer does not feel uncomfortable in the crotch.
Moreover, it is preferable that the liquid guide sheet 80 enables the urine to move between the absorbent bodies 20d that are spaced apart from each other on the left and right.
When using the absorbent article, the amount of urine absorbed by the left and right absorbent bodies may be significantly biased depending on the posture of the wearer, the wearing position, and the like. In such a case, when the absorbent article of the present invention has a liquid guide sheet, the urine moves from the absorber that has absorbed a large amount of urine to the less, and as a result, the bias is alleviated. Thereby, the substantial urine absorption amount and usable time of an absorbent article become long.

  The liquid guide sheet 80 is not particularly limited as long as it has a flow path that allows urine movement, but it is preferable that the liquid guide sheet 80 does not have body fluid absorbability or body fluid retention because the urine moves quickly. . Specifically, a concavo-convex sheet member (hereinafter referred to as an “open / recessed concavo-convex sheet member”) having an opening in a convex portion to be described later is preferably exemplified.

FIG. 11 is a schematic perspective view showing an example of an apertured uneven sheet member having apertures on all of the convex portions. A liquid guide sheet 80 which is an apertured uneven sheet member shown in FIG. 11 has a large number of projections 81 that form convex portions, and each projection 81 has an aperture 82 at the apex thereof. In the apertured concavo-convex sheet member, a part of the convex part may have an aperture, or the entire convex part may have an aperture.
The perforated concave-convex sheet member has a concave-convex surface having concave portions and convex portions as at least one surface. In the perforated concave-convex sheet member, a large number of concave portions are connected to function as a body fluid flow path. The perforated uneven sheet member has an advantage that the flow of body fluid is not hindered even if the convex part is slightly collapsed during use.
Further, in the apertured uneven sheet member, the aperture also functions as a body fluid flow path.
In the present invention, it is preferable to use the apertured concave-convex sheet member with the wider side of the aperture (the surface not visible in FIG. 11) facing the wearer.

Examples of the material of the apertured uneven sheet member include a body fluid impermeable film made of a resin such as PE, PP, PVA, and urethane.
Specific examples of the apertured concavo-convex sheet member include those proposed by the present inventor in WO 02/065965.

  When an apertured uneven sheet member is used as the guide sheet, a body fluid remains in the aperture, a liquid residue is generated, and so-called rewetting value may be deteriorated. In this case, it is preferable to use a hydrophilic diffusion sheet in combination on the lower side of the apertured uneven member. Thereby, since the bodily fluid which exists in an opening | penetration osmose | permeates a hydrophilic diffusion sheet and moves, a rewet value becomes low significantly. Moreover, it is prevented that the apertured uneven sheet member is displaced from the leak preventer, and the shape stability is also improved.

As the hydrophilic diffusion sheet, a hydrophilic nonwoven fabric having a relatively low basis weight is preferably used. Examples of the hydrophilic nonwoven fabric include tissue or hydrophilic nonwoven fabric containing rayon, cotton, wood pulp and the like. Specific examples include tissue paper, rayon spunbond (for example, TCF, manufactured by Futura Chemical), cotton spunlace, rayon / PP mixed spunlace, and rayon / PET mixed spunlace.
Further, non-woven fabrics made hydrophilic by surface-treating synthetic nonwoven fabrics such as PP, PE or PET spunbond nonwoven fabrics, PP thermal pound nonwoven fabrics, and PE / PET through-air nonwoven fabrics with a surfactant or the like.
The apertured concavo-convex sheet member and the hydrophilic diffusion sheet may be simply overlapped and laminated, or may be combined by hot melt, thermal lamination, or the like.

It is preferable to use a bodily fluid impermeable sheet in combination under the hydrophilic diffusion sheet. Thereby, the body fluid is not temporarily stored between the hydrophilic diffusion sheet and the sheet portion of the leak preventer, and quickly moves to the bag portion of the leak preventer. Examples of the material for the body fluid impermeable sheet include films made of resins such as PE, PP, PVA, and urethane.
The hydrophilic diffusion sheet and the body fluid impermeable sheet may be simply stacked and laminated, or may be combined by hot melt, thermal lamination or the like.
Moreover, you may use combining a hole uneven | corrugated sheet | seat member and a bodily fluid impermeable sheet | seat, without using a hydrophilic diffusion sheet.
The perforated uneven sheet member and the body fluid impermeable sheet may be simply overlapped and laminated, or may be combined by hot melt, thermal lamination or the like.

  In FIG. 10, the liquid guide sheet 80 is disposed on the lower side of the absorber 20d, but the liquid guide sheet may be disposed on the upper side, or may be disposed on both the upper side and the lower side. .

Furthermore, when the absorbent body is a sheet-like absorbent body formed by coating a non-woven fabric with a superabsorbent resin, the non-woven fabric is preferably formed into a tube shape with the side coated with the superabsorbent resin being the inner side. This is one of the embodiments.
FIG. 12 shows an example of a sheet-like absorbent body (hereinafter referred to as “tubular absorbent body”) formed into a tube shape with the non-woven fabric coated with a superabsorbent resin as the inside, and an absorbent article using the same. It is a schematic diagram shown. 12 (A) to 12 (C) are lateral end views of the tubular absorbent body, and FIGS. 12 (D) to 12 (F) are lateral end views of absorbent articles using the tubular absorbent body. 12 (A) and 12 (D) are before urine absorption, FIG. 12 (B) and FIG. 12 (E) are in the early stage of urine absorption, and FIG. 12 (C) and FIG. 12 (F) are urine absorption. Late.
A tubular absorbent body 20e shown in FIGS. 12A to 12C is formed by coating a superabsorbent resin 24 on a nonwoven fabric 22 in a plurality of strips that are long in the front-rear direction. Although the tubular absorbent body 20e shown in FIG. 12 has a shape close to a plane before urine absorption (see FIG. 12A), it becomes closer to a cylindrical shape as urine is absorbed (FIG. 12 ( (See B) and FIG. 12C.)
The absorbent article 100n shown in FIGS. 12D to 12F is basically the same as the absorbent article 100l, but differs in that a tubular absorbent body 20e is used. In the absorbent article 100n, when the tubular absorbent body 20e absorbs urine, a space is formed in the central portion in the left-right direction (see FIG. 12F). Thereby, urine becomes easy to move to the back side. Moreover, since a wearer's crotch part and a 1st leak preventer become difficult to contact, a wearer's discomfort becomes less.

Moreover, in the absorbent article of the present invention, it is one of preferred embodiments that the pair of side portions is formed in a pleat shape folded in two or more stages.

In FIG. 13, elements other than the first leak preventer and the absorber are omitted. In FIG. 13, a white member is a first leak preventer, and a hatched member is an absorber.
In the absorbent article shown in FIG. 13, the pair of side portions of the first leak preventer are each formed in a pleat shape folded in two stages. Thereby, since the volume of the space which the 1st leak preventer can form becomes large, the amount of absorbers can be increased and the amount of absorption of urine can be increased.

When the pair of side portions are each formed in a pleat shape folded in two or more steps, the absorber is disposed in at least two of the two or more step spaces defined by the pair of side portions. Is a preferred embodiment.
FIG. 14 is a schematic lateral end view showing another example of the absorbent article according to the present invention.

The rear leak preventer 92 is coupled to the bottom surface portion 12 of the first leak preventer 10 and a portion from the rear end of the pair of side portions 14 to the rear side of the upper portion, The side opening is closed.

In the standing and sitting position, the absorbent article 100 of the present invention is worn in a U-shaped state in which the front side and the rear side are up and the center is down, so that urine and feces leak from the front and rear openings. There is almost no leakage, but there is a risk of leakage in the supine and prone positions.
In the absorbent article 100o of the present invention, the front leak preventer 90 and the rear leak preventer 92 are combined with the first leak preventer to form a bag. Thereby, the front leak preventer 90 has the discharged urine and feces (if the internal space is separated into the front urine absorption space and the rear stool storage space, urine) first Leakage from the front opening of the leak preventer 10 is prevented. In addition, the rear leak preventer 92 prevents the discharged urine and stool (if the internal space is separated into the front urine absorption space and the rear stool storage space) from the first prevention Leakage to the outside is prevented from opening after the leaking body 10.

As in the case of the pair of side portions of the first leak preventer 10, the front leak preventer 90 and the rear leak preventer 92 are one of the preferred embodiments having an edge shape holding member at the edges thereof. When the edge shape holding member is provided, urine and feces are more difficult to leak. In this case, the edge shape holding member may be separate from the edge shape holding member of the first leak preventer 10, and the edge shape holding member 30 of the first leak preventer 10 is extended.

FIGS. 24-27 is a schematic diagram showing another absorbent article of the present invention in the form of a tape-type diaper. 24 is a plan view, FIG. 25 is a longitudinal end view taken along line XXV-XXV in FIG. 24, and FIGS. 26 (A) to 26 (C) are respectively XXVIA-XXVIA lines in FIG. FIG. 27 is a lateral end view taken along line XXVIB-XXVIB and line XXVIC-XXVIC, and FIG. 27 is a perspective view showing a state when worn.

In the absorbent article 320, the sheet-like first leak preventer 202c rises on the left and right sides to form a side portion 213c, and the side portion 213c is folded back to the inside. An edge shape holding member 214c is provided over almost the entire length at the edge of the side portion 213c of the first leak preventer 202c.
The front portion of the edge shape holding member 214c is located on both sides and the front side of the urethral opening when the absorbent article of the present invention is worn, and the upper surface thereof is in contact with the wearer's body. Is fixed elastically so that the urethral opening does not come into direct contact with the absorbent article, or even when contacted, no strong pressure is applied to the urethral opening. By doing in this way, the feeling of pressure to the urethral opening at the time of wear can be eliminated. In addition, since the space formed between the two left and right edge shape holding members 214c is a flow path for urine, only the wearer's urethral opening and its surroundings are wetted, and other parts are not wetted. Can urinate.
Further, on the front side of the absorbent article 320, the genitals are accommodated between the left and right edge shape holding members 214c, and the front edge shape holding member 214c is in close contact with the wearer's body.

  On the rear side of the absorbent article 320, the edge shape holding member 214c comes into close contact with the wearer's skin along the roundness of the buttocks, and the rear edge shape holding member 214c is attached to the wearer's body. Close contact with.

The left and right side walls of the first leak preventer 202c are formed in a pleat shape, and are divided into upper and lower stages by a folded portion in the middle. As a result, a larger amount of urine can be absorbed, and it can withstand long-time wearing.
A second leak preventer 204c is provided at the upper rear portion of the first leak preventer 202c, and a stool processing sheet 221c is provided thereon. In addition, a substantially rectangular absorbent body 203c is formed from the lower front part of the first leak preventer 202c to the lower side of the second leak preventer 204c and at the upper front part of the first leak preventer 202c. It is divided into left and right. That is, the absorbent body 203c has two layers on the front side and one layer on the rear side of the absorbent article 320. The absorber 203c is accommodated in the space formed by the side portion of the first leak preventer 202c, and only a part is exposed.
Thus, since the absorber 203c which exists under the 2nd leak preventer 204c is only one layer, it is easy to hang down below, when a stool is received. That is, the amount of feces received is increasing. In particular, in this embodiment, since the front center portion of the second leak preventer 204c is coupled to the member (here, the liquid guide sheet 218c) and the coupling member 226c, the volume of the stool receiving area is previously determined. Is getting bigger.
In addition, since the absorber 203c exists separately on the left and right, when the absorber 203c absorbs urine, the volume at the center becomes larger.

The longitudinal direction near the center of the bridging member 207c is provided, which is the front urine receiving space S _1, the rear side is flights accommodating space S _2. The bridging member 207c has a rod-like urine stop portion 208c and a stool stop portion 209c each having a substantially oval cross section. The urine stop portion 208c is inclined forward to prevent urine from moving rearward. The stool stop portion 209c is inclined rearward to prevent the stool from moving forward. The bridging member 207c is provided over the entire width of the first leak preventer 202c in the left-right direction.
The lower surface of the bridging member 207c and the upper surface of the front end portion of the second leak preventer 204c are directly coupled by the coupling portion 217c. The coupling part 217c can be formed by an adhesive such as a heat-sensitive adhesive.

In the feces processing space S _2, by only disposing the absorber 203c in the lower part of the folding of the first leak preventer 202c, while securing the absorption capacity, the space for the stool contained in the upper portion When the lower absorbent body 203c is formed and absorbs urine and expands, a large space for stool storage is secured in the central portion. In particular, a portion of the center of the second leak preventer 204c is bonded to the liquid guide sheet 218c underlying the absorber 203c, as the absorber 203c of the left and right stool processing space S ₂ is inflated, the second The center of the leak preventer 204c forms a recess, and a space for storing feces is more effectively secured.

As described above, the absorber 203c is provided so as to be separated from the left and right, and has a tubular shape as shown in FIG. 12A, so that it easily expands due to absorption of urine.
In addition, when urine flows between the two tube-like absorbent bodies 203c, the absorbent body 203c continuously present from the front body under the second leak preventer 204c effectively absorbs urine. Can be done.
Furthermore, by not allowing the absorbent body to exist directly under the urination opening, the absorbent body will not be uncomfortable even after the absorbent body absorbs urine and swells. In addition, since the left and right absorbers 203c support the body, the feeling of pressure on the urethral opening is also reduced.

  A liquid permeable urine introduction part forming member 206c is disposed below the front end of the second leak preventer 204c. Therefore, the urine stopped by the urine stop portion 208c passes through the liquid-permeable urine introduction portion forming member 206c and moves to the lower side of the second leak preventer 204c.

  The upper surfaces of the left and right sides of the second leak preventer 204c are coupled to the side part 213c of the first leak preventer 202c by the coupling part 217c. This prevents stool from leaking from the left and right of the second leak preventer 204c.

On the upper side of the second leak preventer 204c, a stool processing sheet 221c is provided. The stool processing sheet absorbs water from stool, particularly soft stool, and prevents the stool from spreading over a wide area. Further, the stool receiving sheet also functions as a skin contact sheet when not defecation.
As the stool processing sheet, for example, a water-absorbing nonwoven fabric made of pulp or the like, specifically, kinocros manufactured by Oji Kinocloth Co., Ltd. is preferably used. In particular, brushed non-woven fabrics are preferable in that they can be entangled and fixed with soft stool.

  Similar to the first embodiment, a skin contact sheet 205c is provided on the absorber 203c arranged on the upper part of the first leak preventer 202c.

A liquid guide sheet 218c is provided below the absorber 203c disposed below the first leak preventer 202c.
The liquid guide sheet 218c is not particularly limited as long as the liquid guide sheet 218c has a flow path that allows urine to move. However, the liquid guide sheet 218c does not have body fluid absorbability or body fluid retention, which is preferable in terms of quick movement of urine. . Specifically, the uneven | corrugated sheet | seat member (open hole uneven | corrugated sheet member) which has an opening in a convex part is mentioned suitably.
The liquid guide sheet 218c is arranged in the lower part of the two-stage structure formed by the first leak preventer 202c so as to be arranged immediately above the first leak preventer 202c so as to continue from the front body to the rear body. Thus, the urine discharged into the urine processing space S ₁ is instantly spread over the entire lower stage, and serves to help the absorber 203c be used without waste.

  A belt-like waist band 220c is provided at the rear end of the first leak preventer 202c, and a detachable member 222c is provided at both ends thereof. A detachable member 223c is provided on the lower surface of the front end of the first leak preventer 202c. The detachable member 222c and the detachable member 223c are detachable from each other. For example, it comprises various surface fasteners.

In the third embodiment, since the urine storage space S ₁ and the stool storage space S ₂ are independent of each other, separation of urine and stool can be performed almost completely.
In Embodiment 3, when it is difficult for the wearer to wear the wearer himself / herself, the assistant can wear the wearer while confirming the position of the urethra mouth and anus of the wearer.

Is shorter. Further, a spacer 228d is disposed so as to overlap the rear end of the second leak preventer 204d. The spacer 228d is covered with a rear leak preventer 216d connected to the first leak preventer 202d.
Thus, in particular, in the supine position and the like, even if the feces receiving space S ₂ as entered urine, it is possible to move the urine to quickly absorb body 203d.

Second, a front leak preventer 215d connected from the front portion of the first leak preventer 202d is provided, and an edge shape holding member 224d is provided at the edge thereof.
Thereby, in the prone position etc., it is possible to prevent urine from being stored by the front leak preventer 215d and leaking to the abdomen.

Third, in the front body, the absorbent body 203d is folded in two so as to sandwich the skin contact sheet 205d in the upper part, and the left and right ends of the skin contact sheet 205d and the liquid guide sheet 218c are sandwiched in the lower part. It is arranged in half.
As a result, the first leak preventer 202d expands as the absorber 203d expands, and a larger volume for urine absorption is easily secured.

In the absorbent article of the present invention, the second leak preventer can be detachable. In this case, after receiving the stool, the second leak preventer can be removed and discarded. And an unused 2nd leak preventer can be mounted | worn and used again. Moreover, it can also be used as a normal diaper which is not equipped with an unused second leak preventer and does not separate urine and feces.
Similarly, when the absorbent article of the present invention has a stool processing sheet, the stool processing sheet can be attached and detached. Then, an unused stool processing sheet can be attached and used again. Further, it can be used without attaching an unused stool processing sheet.

  The structure which makes a 2nd leak preventer etc. detachable is not specifically limited. For example, a mode in which only the stool processing sheet is removable, a mode in which only the second leak preventer is removable (when there is no stool processing sheet), a second leak preventer and a urine / feces stop member are detachable A certain aspect and the aspect which can attach or detach the 2nd leak preventer, a urine / feces stop member, and a urine introduction part formation member are mentioned. When the urine / feces stop member is detachable, only a part thereof (for example, the urine stop portion or the stool stop portion) may be detachable, or all of the urine / feces stop member may be detachable.

  These detachable members may be detachable independently or may be detachable integrally.

As mentioned above, although the absorber article of the present invention was explained based on each embodiment of illustration, the present invention is not limited to these, for example, the composition of each part is arbitrary which can exhibit the same function Can be replaced with configuration.
Moreover, it can also be set as another embodiment by combining arbitrarily the structure of each part in each embodiment.

  The absorbent article of the present invention is suitably used for any use for adult men, adult women, and children.

Hereinafter, the present invention will be specifically described with reference to examples. However, the present invention is not limited to these.
1. Absorbent article As an example, the absorbent article of the present invention shown in FIGS. 24 to 27 was used. As the absorbent, a highly water-absorbent sheet obtained by coating a SAP dispersion slurry on a non-woven fabric (MegaThin (registered trademark), manufactured by Japan Absorbent Technology Co., Ltd., SAP basis weight 140 g / m ² ) Was used.
Table 1 shows the content of the superabsorbent sheet, the design dehydration absorption amount, and the design free absorption amount in each part of the absorbent article. The designed free absorption amount was determined in accordance with the provisions of “Test method for absorption amount of superabsorbent resin” in JIS K7223-1996. The designed dehydrated absorption amount was obtained by measuring the design free absorption amount and then dehydrating by centrifugation at 1,000 G for 10 minutes.

2. Wear test As a wearer, 4 healthy subjects with normal urination and defecation mechanisms (male 1:38 years old, males 2:64 years old, females 1:32 years old, females 2:54 years old) were given absorbent articles. It was worn, and urination and defecation were performed as follows.
First, the wearer was maintained in the standing position, the sitting position, the lying position and the supine position, and urinated when feeling normal urine. When the urination was completed, the absorbent article was removed, and the amount of urine absorbed was measured. Next, the same absorbent article was worn, and the amount of urine absorbed was measured in the same manner.
Thereafter, the same absorbent article was worn in the standing position and the sitting position, and the stool was defecate when the stool was felt. When the defecation was completed, the absorbent article was removed, the amount of captured stool was measured, and the presence or absence of dirt on the absorbent article and the wearer and the degree of separation of the urine were observed.

Table 2 shows the average of the amount of urine absorbed by four people in the first and second urination.
As is clear from Table 2, the amount of urine absorbed is significantly higher than the designed dehydrated water absorption in any body position, and in particular, in the standing and sitting positions, it reaches a high level of the same level as the designed free water absorption. did.

Table 3 shows the amount of stool captured and the presence or absence of dirt on the absorbent article and the wearer.
As is apparent from Table 3, the stain on the absorbent article after defecation was not observed or was slight even when observed.
No wear on the wearer after defecation was observed. Here, the wearer's kidney in Table 3 refers to the portion of the buttocks excluding the perianal area. Therefore, the fact that the area other than the area around the anus that becomes dirty with the discharge of stool was not stained indicates that the stool was firmly captured in the stool receiving group.
