Hereinafter, an absorbent article according to the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings. In the present specification, when the absorbent article of the present invention is actually worn, the side closer to the wearer's skin is referred to as “upper” and the far side is referred to as “lower”. Further, when the absorbent article of the present invention is actually worn, the side corresponding to the front side of the wearer's body is referred to as “front”, and the side corresponding to the rear side is referred to as “rear”. Moreover, in order to make an understanding easy in each figure, the member which is actually contacting may be shown spaced apart.
FIG. 1 is a schematic diagram illustrating an example of an absorbent article according to the present invention. 1A is a plan view, and FIG. 1B is a lateral end view taken along line IB-IB in FIG. 1A. In FIG. 1A, the skin contact sheet 80 is omitted.
In each plan view in the attached drawings, the front side of the absorbent article or the like is positioned on the upper side of the drawing.

  The absorbent article 100 of the present invention basically includes a sheet portion 20 and a leak preventer 10 having two bag portions 30 that are provided on the upper side of the sheet portion 20 so as to be spaced apart from each other on the left and right sides. Between at least one layer disposed in each of the two bag portions 30 and containing the superabsorbent resin and capable of absorbing bodily fluids, and the absorber 40 disposed in each of the two bag portions 30 A first guide sheet 50 having an opening and a flow path for moving body fluid, and two cushion-like strips 60 provided on the upper side of the first guide sheet 50 so as to be separated from each other left and right. It comprises.

The leak preventer 10 includes the sheet portion 20 and the two bag portions 30 as described above. As the material of the sheet part 20 and the two bag parts 30, those 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.

The seat part 20 and the two bag parts 30 may be comprised integrally, and may be comprised by combining a separate member. Moreover, both the sheet | seat part 20 and the two bag parts 30 may be comprised from the some member.
The shape of the sheet portion 20 is not particularly limited. The sheet | seat part 20 may be substantially planar shape as FIG. 1 shows, and may be bend | folded.
The two bag portions 30 are provided on the upper side of the sheet portion 20 so as to be separated from each other in the left-right direction, and are provided in a state where the opening portions face each other. The two bag portions 30 are preferably bilaterally symmetric.
Moreover, the two bag parts 30 may be connected in the front part and / or the rear part. In the embodiment shown in FIG. 1, the two bag portions 30 are connected at the rear portion.

The absorbent body 40 used in the present invention is not particularly limited as long as it can absorb body fluids. For example, a powdery absorbent body can be used, but in view of form stability, possibility of dropping off, and the like. A sheet-like absorber is preferred.
Among the sheet-like absorbers, a superabsorbent sheet containing SAP of 50% by mass or more, preferably 60 to 95% by mass is preferable.

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 raised nonwoven fabric and fixed with a hot melt binder, emulsion binder, 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.

The superabsorbent sheet is disposed in at least one layer in each of the two bag portions 30. That is, the superabsorbent sheet disposed in the bag portion 30 may be one layer or two or more layers (multiple layers).
In addition, the super absorbent sheet can be placed in the bag portion 30 in a folded state.

The first guide sheet 50 is disposed between the absorbent bodies 40 disposed in each of the two bag portions 30.
The first guide sheet 50 has an opening and a flow path for moving body fluid. The urine discharged from the wearer's urethral opening m between the two bag portions 30 of the leak preventer 10 (hereinafter referred to as “body fluid receiving region”) passes through the opening of the first guide sheet 50 and is below the urine. Furthermore, it moves to the absorber 40 promptly through the flow path of the first guide sheet 50. Therefore, the wearer does not feel uncomfortable in the crotch.

Moreover, it is preferable that the 1st guide sheet | seat 50 enables the movement of the bodily fluid between the absorbers 40 arrange | positioned at each of the two bag parts 30. FIG.
When using the absorbent article, the amount of body fluid absorbed by the absorbent body arranged in the two bag portions may be greatly 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 guide sheet, the body fluid moves from the absorber that has absorbed a large amount of the body fluid to the less, and as a result, the bias is alleviated. Thereby, the substantial bodily fluid absorption amount and usable time of an absorbent article become long.

  The first guide sheet 50 is not particularly limited as long as it has a structure that has an opening and a flow path that allows the movement of bodily fluids. However, the first guide sheet 50 does not have bodily fluid absorbability or bodily fluid retention, but can quickly move bodily fluids. This is preferable. 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. 2 is a schematic perspective view showing an example of an apertured uneven sheet member having apertures in all of the convex portions. The first guide sheet 50, which is an aperture uneven sheet member shown in FIG. 2, has a large number of projections 51 that form convex portions, and each projection 51 has an aperture 52 at its apex. 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 a concave portion and a convex portion 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. 2) facing the wearer. As will be described later, the body fluid supplied to the first guide sheet 50 moves to the lower side of the first guide sheet 50 through the opening, and then moves to the absorber 40. Therefore, when the opening / recessing sheet member has the wider opening on the wearer side (upper side), the recesses can be connected to the lower side and sufficiently function as a body fluid flow path.

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. In FIG. 1, a bodily fluid impermeable sheet 55 is laminated on the lower side of the first guide sheet 50 made of an apertured uneven sheet member.
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.

  The two cushion-like strips 60 are provided on the upper side of the first guide seat 50 so as to be separated from each other in the left-right direction. When the absorbent article 60 of the present invention is worn, the cushion-like belt-like body 60 is positioned on both sides of the urethral opening and its upper surface comes into contact with the wearer's body to elastically fix the absorbent article, The urethral orifice should not be in direct contact with the absorbent article, or a strong pressure will not be applied to the urethral orifice even if contacted. By doing in this way, the feeling of pressure to the urethral opening at the time of wear can be eliminated. Moreover, since the space formed between the two cushion-like strips 60 becomes a flow path for urine, the urethra mouth of the wearer and its surroundings are only wetted, and urination is performed without wetting other parts. Can do.

  Examples of the material of the cushion-like belt-shaped body 60 include a synthetic rubber sheet having a relatively low hardness, an elastic tube, a foam (for example, made of PU, PP, PP / EVA), and a bulky and compression resistance (so-called resilience). ) High non-woven fabric.

FIG. 3 is a schematic perspective view showing an example of a cushion-like belt.
Each of the two cushioning strips 60 shown in FIG. 3 has a lateral width of a, a longitudinal length of b, a vertical height of c, and both The distance is d.
The width a of the two cushion-like strips 60 is preferably 5 mm or more, and more preferably 10 to 50 mm. Within the above range, the wearer's body surface can be more stably supported.
The length b of the two cushioning strips 60 is preferably 20 mm or more, and more preferably 50 to 150 mm. Within the above range, the wearer's body surface can be more stably supported.
The height c of the two cushion-like strips 60 needs to be such that it does not come into contact with the urethral opening when the absorbent article of the present invention is deformed into an inverted V shape when worn. Accordingly, the height c needs to be appropriately selected depending on the cushioning property of the cushioning strip 60, but is generally preferably 2 mm or more, and more preferably 5 mm or more. Within the above range, the wearer's body surface can be more stably supported. Moreover, it is preferable that it is 15 mm or less from the point of cost.

The distance d between the two cushion-like strips 60 is preferably 5 mm or more, more preferably 7 to 30 mm, and even more preferably 10 to 25 mm.
It can prevent reliably that a urethral opening contacts an absorber article as it is the said range. It is also possible to prevent the small labia from coming into contact with the absorbent article. When the urethral opening and labia are kept in contact with each other, there is no feeling of pressure on the urethral opening, the urine discharge state is not affected, and there is no pressure on sensitive areas, and there is no discomfort. In addition, rash is unlikely to occur. Furthermore, when the absorbent article of the present invention is deformed into an inverted V shape when worn, it is possible to maintain a non-contact state even if the height c is not so high.

Moreover, it is preferable that the absorbent article 100 of the present invention further includes a skin contact sheet 80 as shown in FIG. When the skin contact sheet 80 is provided, the surface feel when worn is excellent. In particular, when the first guide sheet 50 and the second guide sheet 70 described later have irregularities and the surface feel is hard, the effect of improving the surface feel is great.
The skin contact sheet is not particularly limited as long as it is permeable to body fluids, and a known one that has been conventionally used as a top sheet can be used. Specifically, for example, a nonwoven fabric of synthetic fibers such as a PP nonwoven fabric, a PET nonwoven fabric, and a PE nonwoven fabric can be used. A dry nonwoven fabric obtained by mixing hydrophilic fibers such as rayon and cotton and synthetic fibers can also be used.
The skin contact sheet 80 may be disposed only in a portion that directly contacts the wearer's body surface. Specifically, it is preferably disposed between the two bag portions 30 of the leak preventer 10. For example, as shown in FIG. 1 (B), it is arranged over two cushioning strips 60. Or it arrange | positions over the 2nd guide sheet 70, as FIG.5 (B) mentioned later shows.

In addition, as shown in FIG. 1, the absorbent article 100 of the present invention preferably further includes a peripheral edge shape retaining material 90 on at least a part of the peripheral edge of the upper portion of the opening of the two bag portions 30. This is one of the embodiments.
The peripheral portion shape retaining member 90 has a function of retaining the peripheral shape of the upper portion of the opening portions of the two bag portions 30. Thereby, it becomes easy for the urine discharged into the space between the two cushion-like strips 60 to move to the inside of the two bag portions 30 through the upper side of the two cushion-like strips 60. Moreover, a wearer's genitals are accommodated between the upper periphery of the opening part of the two bag parts 30 at the time of wear, and become difficult to shift | deviate. This prevents urine from leaking outside the body fluid receiving area. Furthermore, it is possible to prevent uneven and large irregularities from occurring at the peripheral edge during wearing.
It is preferable that the material for the peripheral edge shape retaining member 90 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.

Next, the operation of the absorbent article 100 will be described.
FIG. 4 is a schematic diagram for explaining the operation of the absorbent article according to the present invention. FIG. 4 (A) is a perspective view of the absorbent article, and FIG. 4 (B) is a cross-sectional view taken along line IVB-IVB in FIG. 4 (A). In FIG. 4, only the first guide sheet 50, the cushioning belt-like body 60, and the bodily fluid impermeable sheet 55 are shown among the constituent members of the absorbent article 100 of the present invention.

The absorbent article 100 is worn in a state where the wearer's genitals are located between the upper peripheral edges of the openings of the two bag portions 30 of the leak preventer 10. At this time, the urethral opening m is located between the two bag portions 30 of the leak preventer 10, and the bag portion 30 is in close contact with the inner side of the base of the wearer's legs.
And the urine discharged | emitted from the wearer's urethral opening m to the center part of the upper side of the 1st guide sheet 50 was stably formed by the 1st guide sheet 50 and the two cushioning strips 60. Temporarily stored.
Thereafter, the urine flows through several paths to the bag portions 30 on both sides as indicated by arrows in FIG.
The first path moves from the upper side to the lower side of the first guide sheet 50 through the opening of the first guide sheet 50, and passes through the flow path of the first guide sheet 50 according to gravity to form a cushion-like belt shape. This is a path that passes under the body 60 and further moves outward.
The second path is a path that passes from above the first guide sheet 50 over the cushioning strip 60 according to gravity and further moves outward.
Here, when the urine is temporarily stored on the upper side of the first guide sheet 50 immediately after being discharged from the urethral opening m together with the left and right movements as described above, or the flow path of the first guide sheet 50 When moving on the upper side of the cushion-like band 60, it also moves back and forth.

  Urine that has flowed into the bag 30 is absorbed by the absorber 40. When urine is supplied at a rate that exceeds the absorption rate of the absorber 40, urine that has not been absorbed by the absorber 40 is temporarily stored in the bag 30 and then absorbed by the absorber 40. .

As described above, the absorbent article of the present invention has an absorbent body mainly in a portion other than the crotch portion when worn, and therefore, particularly after the absorbent body absorbs body fluid and swells, the conventional absorbent article. There is no noticeable discomfort. In addition, since the urethral orifice does not directly contact the absorbent article, or even when contacted, no strong pressure is applied to the urethral orifice, there is no feeling of pressure on the urethral orifice.
Moreover, since the absorbent article of the present invention only needs to have a structure covering only the periphery of the urethral orifice, urine and feces can be separated and processed.
Furthermore, in the absorbent article of the present invention, urine leaks to the outside of the body fluid receiving area when the peripheral shape retaining material is further provided at least at a part of the peripheral edge of the upper part of the opening of the two bag portions. Is prevented, flows to the bag portion reliably, and is absorbed by the absorber.

Hereinafter, another example of the preferred embodiment of the present invention will be described in more detail.
FIG. 5 is a schematic view showing another example of the absorbent article of the present invention. 5A is a partially cutaway plan view, and FIG. 5B is a lateral end view taken along the line VB-VB in FIG. 5A. In FIG. 5A, the skin contact sheet 80 is omitted.

  The absorbent article 200 of the present invention basically has the same configuration as that of the above-described absorbent article 100 of the present invention, but is further provided on the upper side of the two cushion-like strips 60 so as to be separated from each other on the left and right. The second guide sheet 70 having a flow path for moving bodily fluids extending from the central part of the sheet part 20 to the inside of the two bag parts 30, forwardly on the front side of the bodily fluid receiving area It has a front leakage prevention part 110 for preventing leakage of body fluid, and a rear body fluid stop member 120 for preventing leakage of body fluid to the rear on the rear side of the body fluid receiving area.

The two second guide sheets 70 are provided on the upper side of the two cushion-like strips 60 so as to be separated from each other in the left-right direction, and extend from the center portion of the seat portion 20 to the inside of the two bag portions 30 to move the body fluid. Has a flow path. Since the two second guide sheets 70 are spaced apart from each other on the left and right, they do not directly contact the urethral orifice.
The 2nd guide sheet 70 will not be specifically limited if it has a flow path for moving a bodily fluid. For example, an apertured concavo-convex sheet member, a concavo-convex sheet member, a sheet member having a grooved structure, and a non-woven sheet member can be mentioned. These may be used alone or in combination of two or more.

Examples of the aperture uneven sheet member include the same ones used for the first guide sheet 50. In the case where an apertured uneven sheet member is used as the second guide sheet 70, it can be used in combination with a hydrophilic diffusion sheet and / or a body fluid impermeable sheet, as in the case of the first guide sheet 50. In FIG. 5, a bodily fluid impermeable sheet 75 is laminated on the lower side of the second guide sheet 70 made of an apertured uneven sheet member.
The body fluid impermeable sheet 75 prevents urine from flowing back through the apertures of the apertured uneven sheet member (second guide sheet 70) when the second guide sheet 70 is an apertured uneven sheet member. In particular, the effect is great in the lying position.

FIG. 6 is a schematic perspective view showing an example of a sheet member having a groove-like structure. The sheet member 71 has a groove-like structure 72, and this groove-like structure 72 functions as a body fluid flow path.
The sheet member having a groove-like structure is obtained, for example, by a method in which a groove-like structure that functions as a flow path is imparted to a body fluid impermeable film having thermoformability by thermoforming.

FIG. 7 is a schematic perspective view showing an example of the uneven sheet member. The concavo-convex sheet member 73 shown in FIG. 7 has a large number of protrusions 74 that form convex portions.
The concavo-convex sheet member has a concavo-convex surface having a concave portion and a convex portion as at least one surface. In the concavo-convex sheet member, a large number of concave portions are connected to function as a body fluid flow path. The concavo-convex sheet member has an advantage that the flow of body fluid is not hindered even if the convex portion is somewhat collapsed during use.
Examples of the material of the concavo-convex sheet member include a body fluid impermeable film made of a resin such as PE, PP, PVA, and urethane.

  In a nonwoven fabric sheet member, the internal space functions as a body fluid flow path. The nonwoven sheet member preferably has a high resilience. For example, the present inventor proposed in Japanese Patent Application Laid-Open Nos. 2003-103704 and 2003-103677 is a laminate of a paper layer or a nonwoven fabric layer having a smooth surface and a thick fiber web having a bulky surface and irregularities. Thus, an integrated nonwoven fabric is preferably used.

  In the absorbent article 200 of the present invention, a linked absorbent body 41 is provided instead of the two absorbent bodies 40 in the absorbent article 100. In the absorbent article 200, even if the urine supply amount differs in the left-right direction due to the position of the wearer and the like, the absorbent bodies 41 arranged in the two bag portions 30 are connected, so the comparison is made. Can be absorbed evenly and the pot life becomes longer.

In the absorbent article 200 of the present invention, the peripheral edge shape retaining member 91 is disposed such that the upper peripheral edge of the openings of the two bag portions 30 rises upward.
By adopting such a structure, the wearer's genitals (exogenous organs and pubic hair) can be easily accommodated between the upper peripheral edges of the openings of the two bag portions 30 when worn. This more effectively prevents urine from leaking outside the body fluid receiving area.
In addition, by adopting such a structure, the gap between the upper portion of the opening of the bag portion 30 and the second guide sheet 70 is widened, so that urine can easily flow from side to side and the absorption is accelerated.
Thus, the method of lifting the upper peripheral edges of the openings of the two bag portions 30 inward is not particularly limited. For example, as shown in FIG. Preferably mentioned.

  FIG. 8 is a schematic diagram for explaining the operation of the absorbent article according to the present embodiment. 8A is a perspective view of the absorbent article, and FIG. 8B is a cross-sectional view taken along line VIIIB-VIIIB in FIG. 8A. In FIG. 8, only the first guide sheet 50, the cushioning strip 60, the second guide sheet 70, and the body fluid impermeable sheets 55 and 75 among the constituent members of the absorbent article 200 of the present invention are shown. Yes.

The absorbent article 200 is worn in the same manner as the absorbent article 100.
The urine discharged from the wearer's urethral orifice m to the upper central portion of the first guide sheet 50 passes through several routes to the bag portions 30 on both sides as indicated by arrows in FIG. It will flow.
The first route is the same as the first route in the absorbent article 100.
From the upper side of the first guide sheet 50, the second path passes above the cushioning strip 60 through the upper side of the surface of the second guide sheet 70 and the flow path according to gravity, and further outward. It is a moving route. Since the absorbent article 200 includes the second guide sheet 70, the absorbent article 200 can be easily moved along the second path as compared to the absorbent article 100. Therefore, the rate of urine diffusion and absorption is better.
Here, when the urine is temporarily stored on the upper side of the first guide sheet 50 immediately after being discharged from the urethral opening m together with the left and right movements as described above, or the flow path of the first guide sheet 50 When moving on the upper side of the surface of the second guide sheet 70 or in the flow path, it also moves back and forth.
Urine that has flowed into the bag 30 is absorbed by the absorber 41. When urine is supplied at a rate exceeding the absorption rate of the absorber 41, urine that has not been absorbed by the absorber 41 is temporarily stored in the bag portion 30, and then absorbed by the absorber 41. .
In addition, when the amount of urine supplied varies greatly in the left-right direction due to the body position of the wearer, the urine moves in the left-right direction through the absorber 41 and is absorbed by the absorber 41.

As shown in FIG. 5 (A), the absorbent article 200 of the present invention has a front leakage preventing portion 110 for preventing body fluid from leaking forward on the front side of the body fluid receiving region.
In the absorbent article 100 of the present invention, the urine hardly leaks from the front side of the body fluid receiving region because the front side is up and the rear side is down in the standing position and the sitting position. Since the side can be down and the back side can be up, there is a risk of urine leaking from the front side of the body fluid receiving area.
The front leakage preventing part 110 in the absorbent article 200 of the present invention prevents urine from leaking from the front side of the body fluid receiving area.

In the absorbent article 200 of the present invention, the front leak-proof portion 110 is a bag portion. The front leak-proof portion 110 shown in FIG. 5A protrudes to the front center between the two bag portions 30. The upper peripheral edge of the opening portion of the front leak-proof portion 110 is connected to the upper peripheral edge of the opening portions of the two bag portions 30, and the lower peripheral edge of the front leak-proof portion 110 is connected to the seat portion 20 of the leak preventer 10. It is integrated. Therefore, the inside of the front leak-proof portion 110 communicates with the inside of the two bag portions 30.
A guide sheet for moving body fluid to the two bag portions 30 is preferably disposed inside the front leakage preventing portion 110. As shown in FIG. 5A, the guide sheet may be one in which the first guide sheet 50 is extended.

As shown in FIG. 5A, an absorbent body 115 that contains at least one superabsorbent resin and can absorb bodily fluids can be disposed in the front leakage preventing section 110 formed of the bag section. Thereby, not only can the urine flowing into the front leakage preventing portion 110 be temporarily stored to prevent leakage, but can also be absorbed. In the absorbent article of the present invention, since the discharged urine is quickly diffused by the first guide sheet and the optionally provided second guide sheet, the absorbent body 115 is placed on the front leakage preventing part 110 formed of the bag part. Is not particularly required.
As the absorber 115, the thing similar to the absorber 40 mentioned above can be used.

Like the two bag parts 30, the front leak-proof part 110 made of a bag part is preferably arranged so that the upper peripheral edge of the opening part rises upward. By adopting such a structure, urine is more difficult to leak.
Thus, the method of raising the upper periphery of the opening part of the front leak-proof part 110 which consists of a bag part upwards is not specifically limited, For example, the method of making a periphery a gather shape is mentioned suitably. In this case, it may be gathered separately from the peripheral edges of the two bag portions 30, and is continuously gathered from the peripheral edges of the two bag portions 30, as shown in FIG. Also good.

  Moreover, it is preferable that the front leak-proof part 110 which consists of a bag part has a peripheral part form maintenance material on the lower side of the periphery of the upper part of the opening part similarly to the two bag parts 30. FIG. When it has a peripheral part form maintenance material, it becomes difficult to leak urine. In this case, the peripheral shape retaining material may be separate from the peripheral shape retaining material of the two bag portions 30, and the peripheral shape retaining material 91 of the opening portions of the two bag portions 30 is extended. It may be.

It is preferable that the front leakage preventing part 110 formed of the bag part is lifted upward. With such a structure, the front leak-proof portion 110 is likely to be in close contact with the wearer's body surface (around the pubis).
Moreover, it is preferable that the front leak-proof portion 110 formed of the bag portion is configured to be flexible in that it easily adheres to the body surface.

As shown in FIG. 5A, the absorbent article 200 of the present invention has a rear body fluid stop member 120 on the rear side of the body fluid receiving region. The rear body fluid stop member 120 prevents urine from leaking from the rear side of the body fluid receiving region.
The material of the rear body fluid stop member 120 is not particularly limited as long as it is liquid-impermeable as a whole. For example, foam (for example, made of PU, PP, PP / EVA); A material coated with a porous material; a material in which a foam is used as a core, a periphery is coated with a hydrophilic material, and a periphery thereof is coated with a nonwoven fabric or a body fluid impermeable sheet. When coating with a body fluid impermeable sheet, the body fluid impermeable sheet 75 can be extended and coated.

The rear body fluid stop member 120 shown in FIG. 5 (A) has a rod shape and is arranged at the rearmost part of the body fluid receiving area so as to prevent urine from leaking from the rear side and flow to the bag parts 30 on both sides. To.
As shown in FIG. 5A, the rear body fluid stop member 120 may have both end portions extending into the two bag portions 30. Further, both end portions of the rear body fluid stop member 120 can extend to arbitrary positions in the two bag portions 30.

The absorbent article 200 is not in contact with the urethral orifice m and the small labia l and the peripheral edge is located outside the large labia L. In this aspect, since the gap between the peripheral edge of the opening and the second guide sheet 70 is wide and the adhesion between the peripheral edge and the large labia L is high, the bag part 30 flows over the second guide sheet 70. There is very little risk of urine leaking out on the way to the path. Among these, the state shown in FIG. 16B is more preferable.
The absorbent article 200 shown in FIG. 16 (D) has a peripheral edge shape retaining material 91, and the peripheral edge is warped outward. The absorbent article 200 is not in contact with the urethral orifice m and the small labia l and the peripheral edge is located outside the large labia L. In this aspect, since the gap between the peripheral edge portion of the opening and the second guide sheet 70 is wide, there is a risk that urine leaks out in the middle of the path that flows on the second guide sheet 70 and reaches the bag portion 30. small. In addition, this aspect has extremely high adhesion to the body surface because the peripheral edge is warped outward.

<Front leakage prevention part and rear body fluid stop member>
As described above, when the wearer uses the absorbent article in the standing position and the sitting position, the discharged body fluid moves relatively stably to the left and right bag portions according to gravity, and is absorbed. In the position, lying position and prone position, urine may leak from the front side of the body fluid receiving area. In particular, in the lying position and the prone position, it is likely to leak from the front side, and in the supine position, it is likely to leak from the rear side. Therefore, it is preferable to provide a front leakage preventing portion and a rear body fluid stop member.

As the front leakage preventing part, it may be constituted by a bag part like the absorbent article 200 described above, but it is constituted by a front body fluid stop member similar to the rear body fluid stop member. Or a combination of both.
When the front leak-proof part is composed of a combination of the bag part and the front body fluid stop member, the front body fluid stop member reduces the momentum of the urine when the urine flows out to the front side in a prone position etc. The amount and speed of urine moving to the bag portion are suppressed. Further, in the prone position, the bag portion is prevented from being crushed by the weight of the wearer, and the space inside the bag portion is secured. Therefore, it is preferable to use a cushioning material as the front body fluid stop member.
