  Conventionally, in order to enhance the capacity for storing excrement of the absorbent article or to enhance the leakage prevention function, an absorbent article having a top sheet, a back sheet, and an absorbent core provided between them has been supplemented. Providing an absorbent member has been proposed. For example, Patent Document 1 discloses a disposable diaper having a top sheet, a back sheet, and an absorbent core provided between the top sheet, an opening penetrating the top sheet and the back sheet in the crotch region of the disposable diaper. An absorbent core in which a bag for accommodating stool is provided in communication with the opening, and the bag is provided over almost the entire area between the liquid-permeable sheet, the liquid-impermeable sheet, and these sheets. A disposable diaper is disclosed.

Japanese Patent No. 3822295

  However, since the disposable diaper disclosed in Patent Document 1 is provided with a bag on the side opposite to the side facing the wearer's skin, the capacity for holding excrement and the leakage prevention function are enhanced. It is bulky and may be difficult to wear when wearing diapers.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an absorbent article that is compact before use and has a high capacity for containing excreta.

  The absorbent article of the present invention capable of solving the above problems is an upper absorbent body having a top sheet, a back sheet, and a first absorbent core provided therebetween; and joined to the back sheet. An absorbent article having a lower absorbent body having an exterior sheet and a second absorbent core; the upper absorbent body has an opening; and the second absorbent core is located below the opening. The lower absorbent body is characterized in that an upward crease is formed at a location where the second absorbent core is provided.

  In the absorbent article of the present invention, since the upward fold is formed in the lower absorbent body, the lower absorbent body is folded in a compact manner before the second absorbent core absorbs body fluid, so that the absorbent article can be easily attached. Become. On the other hand, when the absorbent article is worn, since the lower absorbent body is provided in addition to the upper absorbent body, even if a large amount of excrement such as urine is discharged at a time, the excrement remains in the opening of the upper absorbent body. It passes through to the lower absorbent body, and excrement such as urine can be absorbed by the lower absorbent body, and there is no risk of side leakage. And since the upward crease | fold is formed in the location in which the 2nd absorptive core of the lower side absorber was provided, if a 2nd absorptive core absorbs body fluids, such as urine, a 2nd absorptive core will swell. It acts to moisten and moisten and spread upward folds. As a result, a space between the back sheet and the lower absorbent body is expanded, so that more excrement can be stored in the space, and excrement leakage is prevented.

  The upward fold line of the lower absorbent body is preferably provided below the opening of the upper absorbent body and extends in the front-rear direction of the absorbent article. When an upward fold is provided in this way, excrement such as urine that has reached the lower absorbent body through the opening is easily guided to the second absorbent core, and body fluid spreads throughout the second absorbent core. Therefore, urine and the like are easily absorbed by the second absorbent core. Further, if the fold is provided on the lower side of the opening, the fold is formed in a region where the urine excreted from the wearer hits. Urine and the like are easily absorbed.

  It is preferable that the opening of the upper absorbent body is arranged to be biased forward of the absorbent article, and the second absorbent core of the lower absorbent body is biased to the rear of the opening of the upper absorbent body and is arranged to the exterior sheet. . The lower absorbent body is particularly suitable for absorbing bodily fluids such as urine and menstrual blood. Therefore, it is preferable that the opening be arranged in the front of the absorbent article. Body fluid such as urine that has moved to the lower absorbent body easily moves to the rear side of the opening when the wearer of the absorbent article stands or sits. Therefore, if the 2nd absorptive core is biased and arranged behind the opening, body fluid will become easy to be absorbed effectively.

  It is preferable that the 2nd absorptive core of a lower side absorber contains a water absorbing resin and does not contain a pulp fiber. According to the said structure, it becomes easy to make the thickness of a 2nd absorptive core thin, and it becomes easy to form a crease | fold in a lower side absorber. Moreover, an absorbent article becomes difficult to be bulky and the wearing feeling of an absorbent article improves. Furthermore, when the second absorbent core absorbs body fluid, the water-absorbing resin swells and the upward crease easily spreads, and the lower absorbent body easily stores a large amount of excreta.

  The opening of the upper absorbent body is preferably surrounded by the first absorbent core. According to the configuration, the opening is easily maintained in a predetermined shape, and excrement such as urine is easily transferred to the lower absorbent body through the opening.

  The upward crease of the lower absorbent body extends to the entire lower absorbent body in the front-rear direction of the absorbent article, and downward creases formed on both sides of the upward fold are joined at the front and rear ends of the lower absorbent body, The rear end of the lower absorbent body preferably extends obliquely downward in front of the absorbent article. According to the said structure, while an upward crease | fold becomes easy to be maintained suitably, the mounting | wearing feeling from the crotch part to a buttock part of an absorbent article becomes favorable.

  The absorptive article of the present invention is excellent in excrement accommodation capacity and leakage prevention. Moreover, since the absorbent article of the present invention is compact before use and can absorb its excrement, its capacity can be increased, so it has both ease of wearing and high capacity.

In the figure, the arrow x is defined as the width direction, the arrow y is defined as the front-rear direction, and the direction on the surface formed by the arrows x, y is defined as the plane direction. In addition, a vertical direction with respect to the surface formed by the arrows x and y is defined as a vertical direction (or thickness direction) z.

  The absorbent article 1 is bonded to the upper sheet 2 having the top sheet 3, the back sheet 4, and the first absorbent core 5 provided therebetween, and the outer sheet 12 and the second absorption sheet. A lower absorbent body 11 having a conductive core 13, and the upper absorbent body 2 has an opening 6. The absorbent article 1 is arranged so that the upper absorbent body 2 faces the wearer's skin when worn. In the present invention, the “upper side” means the wearer side when wearing the absorbent article, and the “lower side” is the side opposite to the wearer when wearing the absorbent article, that is, Means outside. The absorbent article 1 absorbs excrement such as urine with the first absorbent core 5 of the upper absorbent body 2 and excretes urine or the like that has reached the lower absorbent body 11 through the opening 6 of the upper absorbent body 2. Objects are absorbed by the second absorbent core 13.

  The top sheet 3 is liquid permeable, and excreta such as urine passes through the top sheet 3 and is absorbed by the first absorbent core 5.

  The backsheet 4 may be liquid permeable or liquid impermeable. The lower absorbent body 11 is provided below the back sheet 4. For example, when the outer edge of the back sheet 4 is completely covered with the lower absorbent body 11, part or all of the back sheet 4 is liquid permeable. May be sex. Further, when the outer edge of the lower absorbent body 11 is inside the outer edge of the back sheet 4, the back sheet 4 on the outer side of the outer edge of the lower absorbent body 11 is liquid impervious, and other than that Part or all may be liquid permeable. Of course, the entire back sheet 4 may be liquid-impermeable. If at least a part of the backsheet 4 is liquid permeable, urine or the like that has migrated onto the lower absorbent body 11 through the opening 6 of the upper absorbent body 2 can also be absorbed by the first absorbent core 5. Become.

  The first absorbent core 5 is provided between the top sheet 3 and the back sheet 4 and absorbs excrement such as urine. As the 1st absorptive core 5, the molded object which shape | molded the absorptive material in the predetermined shape is used, for example, or the absorptive material is covered with covering sheets, such as a paper sheet (for example, tissue paper) and a liquid-permeable nonwoven fabric sheet. Or an absorbent material dispersed on a sheet such as a paper sheet or a liquid-permeable nonwoven sheet can be used. Examples of the absorbent material include hydrophilic fibers such as pulverized pulp fibers and cellulose fibers, and water-absorbing resins such as polyacrylic acid-based, cellulose-based, and starch / acrylonitrile-based materials. The absorbent material preferably contains at least a water absorbent resin. Further, as the absorbent material, a mixture of hydrophilic fibers mixed with an aggregate of hydrophilic fibers may be used.

  The shape of the 1st absorptive core 5 is not specifically limited. Examples of the outer edge shape of the first absorbent core 5 include a rectangular shape, an elliptical shape, an hourglass shape, a gourd shape, and a battledore shape. Moreover, the 1st absorptive core 5 may be formed by arranging a plurality of absorptive core pieces in the planar direction.

  The opening 6 is provided through the upper absorber 2 in the thickness direction. The opening 6 may be provided between, for example, a plurality of absorbent core pieces constituting the first absorbent core 5, and may be provided so as to be surrounded by the first absorbent core 5. However, the opening 6 is preferably surrounded by the first absorbent core 5. In this case, the opening 6 is easily maintained in a predetermined shape, and excrement such as urine is easily transferred to the lower absorbent body 11 through the opening 6. In this case, for example, even if the absorbent article 1 is provided with an elastic member, the opening 6 is easily maintained in a predetermined shape. The opening 6 being surrounded by the first absorbent core 5 means that the periphery of the opening 6 is continuously surrounded by the first absorbent core 5, and the opening 6 is the first absorbent core. It means that the core 5 is provided.

  The shape of the opening 6 is not particularly limited, such as a circle, an ellipse, a rectangle, and an indeterminate shape, but is preferably a shape extending in the front-rear direction (for example, an ellipse or a rectangle). If the opening 6 has a shape extending in the front-rear direction, excrement such as urine can easily move to the lower absorbent body 11 through the opening 6.

  The opening 6 is provided for transferring excrement such as urine to the lower absorbent body 11. In particular, as will be described later, the lower absorbent body 11 is suitable for absorbing bodily fluids such as urine and menstrual blood. Therefore, it is preferable that the opening 6 is arranged in a biased manner in front of the absorbent article 1. In addition, the opening 6 is preferably arranged at the center in the width direction of the absorbent article 1. Note that “front” means a direction from the wearer's back to the abdomen when the absorbent article is worn, and “rear” means the opposite direction.

  The upper absorbent body 2 is preferably provided with a pair of rising flaps 10 on both sides in the width direction of the opening 6. By providing the rising flap 10, side leakage of excrement such as urine can be prevented. The rising flap 10 is formed, for example, by joining side sheets 7 extending in the front-rear direction to both sides in the width direction of the top sheet 3 and providing an elastic member 8 at the inner end in the width direction of the side sheet 7. By providing the side seat 7 and the elastic member 8 in this way, the inner end of the side seat 7 rises toward the wearer's skin by the contraction force of the elastic member 8, and the rising flap 10 is formed. The rising flap 10 or the side sheet 7 is preferably composed of a liquid-impermeable plastic film, a liquid-impermeable nonwoven fabric, or the like.

  The rising flap 10 is preferably provided with an elastic member 9 at the base. By providing the elastic member 9 at the base of the rising flap 10, the upper absorbent body 2 is lifted to the wearer side at the portion where the elastic member 9 is provided, and the upper absorbent body 2 is curved in the front-rear direction. . As a result, the fit of the absorbent article 1 to the wearer is enhanced.

  The lower absorbent body 11 has an exterior sheet 12 and a second absorbent core 13 and is joined to the back sheet 4. The lower absorbent body 11 is provided to absorb excrement such as urine that has migrated through the opening 6. For example, even when a large amount of urine is discharged at a time, the absorbent article 1 can receive and absorb body fluid such as urine with the lower absorbent body 11, thereby eliminating the possibility of side leakage of urine or the like.

  The lower absorbent body 11 is directly or indirectly joined to the lower side of the back sheet 4 of the upper absorbent body 2, and the lower absorbent body 11 is joined to the back sheet 4 around the opening 6. As a result, a space for storing a liquid such as urine is formed between the back sheet 4 and the lower absorbent body 11. The lower absorbent body 11 may be joined to the backsheet 4 at a joint portion provided continuously around the opening 6. The position of the joint is not particularly limited as long as it is formed between the edge of the opening 6 and the outer edge of the backsheet 4.

  The exterior sheet 12 is liquid impermeable. If the exterior sheet 12 is liquid-impermeable, excrement such as urine taken up by the absorbent article 1 can be prevented from leaking outside.

  The 2nd absorptive core 13 should just be provided in the upper absorber 2 side rather than exterior sheet 12, for example, is provided on exterior sheet 12, or is provided between exterior sheet 12 and other sheets. For example, in FIG. 2, the lower absorbent body 11 includes an exterior sheet 12 and a second absorbent core 13, and the second absorbent core 13 is disposed on the exterior sheet 12. In FIG. 3, the lower absorbent body 11 has an exterior sheet 12, a second absorbent core 13, and a second top sheet 14, and the second absorbent core 13 is between the exterior sheet 12 and the second top sheet 14. It is arranged in. Further, in FIG. 3, an intermediate sheet 15 is provided between the second top sheet 14 and the second absorbent core 13. By providing the intermediate sheet 15, body fluid such as urine that has passed through the second top sheet 14 is easily diffused in the plane direction by the intermediate sheet 15, and the absorbability of the body fluid by the second absorbent core 13 is improved. Although FIG. 3 shows an embodiment in which the second top sheet 14 and the intermediate sheet 15 are provided at the same time, the intermediate sheet 15 is not necessarily provided. The second top sheet 14 and the intermediate sheet 15 are preferably liquid permeable.

  As the second absorbent core 13, for example, a molded body obtained by molding the absorbent material into a predetermined shape is used, or the absorbent material is covered with a covering sheet such as a paper sheet (for example, tissue paper) or a liquid-permeable nonwoven fabric sheet. Or an absorbent material dispersed on a sheet such as a paper sheet or a liquid-permeable nonwoven sheet can be used. As an absorptive material, the material which can be used with the 1st absorptive core 5 can be used.

  Although the shape of the 2nd absorptive core 13 is not specifically limited, The 2nd absorptive core 13 is distribute | arranged to the exterior sheet | seat 12 so that at least one part may be located under the opening 6. FIG. That is, the shape of the second absorbent core 13 is not particularly limited as long as at least a part of the second absorbent core 13 is disposed below the opening 6.

  The second absorbent core 13 is preferably disposed on the exterior sheet 12 while being biased to the rear of the opening 6. In this case, it is preferable that the opening 6 is arranged in a biased manner in front of the absorbent article 1. As will be described later, the lower absorbent body 11 is particularly suitable for absorbing bodily fluids such as urine and menstrual blood. Therefore, it is preferable that the opening 6 be arranged in a biased manner in front of the absorbent article 1. When the wearer of the absorbent article 1 stands or sits, body fluid such as urine that reaches the lower absorbent body 11 through the opening 6 easily moves to the rear side of the opening 6. Therefore, if the 2nd absorptive core 13 is unevenly arranged behind opening 6, body fluid will become easy to be absorbed effectively.

  The lower absorbent body 11 is disposed on the exterior sheet 12 so that the second absorbent core 13 is positioned below the opening 6, and has an upward crease at a location where the second absorbent core 13 is provided. 16 is formed. Here, the upward crease means a crease that becomes a mountain fold when the absorbent article is viewed from the upper side, that is, the wearer side. In the lower absorbent body 11, the upward fold 16 is formed, and as a result, downward creases 17 are formed on both sides of the upward fold 16. Since the absorbent article 1 has the upward fold 16 formed in the lower absorbent body 11, the lower absorbent body 11 is folded compactly before the second absorbent core 13 absorbs urine and the like. Therefore, before use, the absorbent article 1 is not bulky and can be easily mounted.

  On the other hand, when the absorbent article 1 is worn, when urine or the like moves to the lower absorbent body 11 through the opening 6, the second absorbent core 13 is disposed so as to be located below the opening 6. Body fluid such as urine is easily absorbed by the second absorbent core 13. And since the upward crease 16 is formed in the location in which the 2nd absorptive core 13 was provided, if the 2nd absorptive core 13 absorbs body fluids, such as urine, the 2nd absorptive core 13 will swell. Or acts to spread the upward fold 16. As a result, the space between the back sheet 4 and the lower absorbent body 11 is widened, and the lower absorbent body 11 has a bag shape, for example, so that more body fluid can be stored. In addition, the upward crease 16 should just be formed in at least one part of the location in which the 2nd absorptive core 13 was provided. For example, when the second absorbent core 13 extends to a portion other than the lower side of the opening 6, the upward fold 16 is formed only in a portion other than the lower side of the opening 6 of the second absorbent core 13. May be.

  The second absorbent core 13 preferably contains a water-absorbent resin so that the upward fold 16 can be easily spread when the second absorbent core 13 absorbs the body fluid. If the 2nd absorptive core 13 contains a water absorbing resin, water absorbing resin will swell by absorption of a bodily fluid, and the upward crease | fold 16 will become easy to spread.

  Furthermore, in order to make it easy to form an upward crease 16 at a location where the second absorbent core 13 is provided, it is preferable that the second absorbent core 13 includes a water absorbent resin and does not include pulp fibers. If the 2nd absorptive core 13 does not contain a pulp fiber, it will become easy to make the thickness of the 2nd absorptive core 13 thin, and it will become easy to form a crease | fold in the lower side absorber 11. FIG. Moreover, the absorbent article 1 becomes difficult to be bulky, and the wearing feeling of the absorbent article 1 is improved. In addition, that the 2nd absorptive core 13 does not contain a pulp fiber means that the 2nd absorptive core 13 does not contain a fluffy pulp fiber. That is, even if the 2nd absorptive core 13 does not contain a pulp fiber, the 2nd absorptive core 13 may be coat | covered or carry | supported by sheets, such as tissue paper. As an aspect in which the second absorbent core 13 includes a water absorbent resin and does not include pulp fibers, for example, an aspect in which the water absorbent resin is supported on one nonwoven fabric; the water absorbent resin is supported between the two nonwoven fabrics. A mode in which the water-absorbent resin is wrapped in a tissue paper; and the like. Moreover, the 2nd absorptive core 13 may consist only of water absorbing resin, and in this case, water absorbing resin will be carry | supported on the exterior sheet | seat 12 directly.

  In the figure, the upward crease 16 extends in the front-rear direction of the absorbent article 1, but the direction in which the crease 16 extends is not limited thereto, and may extend in the width direction of the absorbent article 1, for example. However, the crease 16 preferably extends in the front-rear direction of the absorbent article 1, and the crease 16 is preferably provided below the opening 6. When the fold 16 is provided in this way, body fluid such as urine that has reached the lower absorbent body 11 through the opening 6 is easily guided to the second absorbent core 13, and the body fluid is entirely contained in the second absorbent core 13. Therefore, the body fluid is easily absorbed by the second absorbent core 13. Further, if the crease 16 is provided on the lower side of the opening 6, a crease is formed in a region where the urine etc. excreted from the wearer hits. It spreads and urine is easily absorbed quickly. More preferably, the upward crease 16 extends to the entire lower absorbent body 11 in the front-rear direction of the absorbent article 1.

  The number of the upward creases 16 formed is not particularly limited as long as it is one or more. In the figure, only one upward crease 16 is formed, but two or more creases 16 may be formed. For example, when two upward creases 16 extending in the front-rear direction of the absorbent article 1 are formed, the upward crease 16 is less likely to be formed in the center of the absorbent article 1 in the width direction, and the upward crease 16 is the genital organ. Discomfort caused by touching can be easily reduced. The upper limit of the number of upward fold lines 16 is preferably 6 or less in consideration of the ease of folding the lower absorbent body 11.

  In order for the upward crease 16 to be suitably formed, as shown in FIG. 4, the upward crease 16 extends to the entire lower absorbent body 11 in the front-rear direction of the absorbent article 1, and on both sides of the upward crease 16. The formed downward creases 17 are preferably joined at the front and rear ends 18 and 19 of the lower absorbent body 11. By joining the downward creases 17 at the front and rear ends 18 and 19 of the lower absorbent body 11, the upward crease 16 is easily maintained. The downward creases 17 may be joined together by, for example, joining the creases 17 with an adhesive, or joining the creases 17 by heat or ultrasonic waves. Preferably, the creases 17 are preferably joined by heat welding. In this case, weld portions 20 are formed at the front and rear ends 18 and 19 of the lower absorbent body 11.

  When the downward creases 17 are joined at the front and rear ends 18 and 19 of the lower absorbent body 11, the front and rear ends 18 and 19 tend to be bulky in the thickness direction, and as a result, the wearing feeling may be deteriorated. In particular, the rear end 19 is a portion that is sandwiched between the wearer's crotch part or applied to the buttocks. Therefore, if the rear end 19 is bulky, the wearer feels uncomfortable when sitting. It becomes easy. Therefore, it is preferable that the rear end 19 of the lower absorbent body 11 extends obliquely forward in front of the absorbent article 1. That is, when the absorbent article 1 is viewed from the side in the front-rear direction, the rear end 19 preferably intersects the downward crease 17 at an obtuse angle. If the rear end 19 of the lower absorbent body 11 is formed in this way, the bulkiness of the rear end 19 is reduced, and a feeling of wearing from the crotch to the buttocks becomes good. Similarly, the lower end of the front end 18 of the lower absorbent body 11 may extend obliquely to the rear of the absorbent article 1. In this case, the bulkiness of the front end 18 is reduced, and the feeling of wearing near the lower abdomen is improved.

  Next, the material of each member constituting the absorbent article 1 will be described.

  The top sheet 3, the second top sheet 14, and the intermediate sheet 15 are not particularly limited as long as they are liquid-permeable sheet materials. For example, a nonwoven fabric formed from hydrophilic fibers such as cellulose, rayon, and cotton; and a nonwoven fabric formed from hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon, and the surface of the hydrophobic fibers is the interface Those hydrophilized with an activator can be used.

  The backsheet 4 is not particularly limited as long as it is a liquid-permeable or liquid-impermeable sheet material. As the liquid-permeable sheet material, a material that can be used for the top sheet 3 or the like may be used. As the liquid-impermeable sheet material, a nonwoven fabric formed from hydrophobic fibers such as polypropylene, polyethylene, polyester, polyamide, and nylon, a plastic film, and the like can be used. Moreover, you may use the laminated body of a nonwoven fabric and a plastic film. “Liquid impervious” includes the meaning of “water repellency”.

  The side sheet 7 and the exterior sheet 12 are not particularly limited as long as they are liquid-impermeable sheet materials. As the liquid-impermeable sheet material, the liquid-impermeable sheet material shown in the above description regarding the material of the back sheet 4 may be used.

  When a nonwoven fabric is used as each of the sheet materials, the nonwoven fabric is preferably manufactured by a spunbond method, an air-through method, a point bond method, a melt blow method, an airlaid method, or a combination of these production methods. Moreover, you may use the nonwoven fabric manufactured by SMS method which combined the spun bond method and the melt blow method.

  As an elastic member, the elastic elastic material used for absorbent articles, such as usual disposable diapers, such as a polyurethane thread, a polyurethane film, and natural rubber, can be used. Each elastic member is preferably fixed in a stretched state with a hot melt adhesive. For example, a polyurethane yarn having a fineness of 100 to 2,500 dtex is stretched and arranged at a magnification of 1.1 to 5.0 times and fixed. The bonding means is preferably a rubber-based hot melt adhesive.

  Although the case where the absorbent article of this invention is applied to a urine pad was demonstrated above, the absorbent article of this invention is not limited to a urine pad, It can apply also to a disposable diaper, a sanitary napkin, etc.

  When the absorbent article is a disposable diaper, the disposable diaper is an open-type disposable diaper that is provided with a pair of fastening members on the left and right sides of the back or front abdomen and is formed into a pants shape when worn by the fastening member. A pants-type disposable diaper in which a waist opening and a pair of leg openings are formed by joining the front abdomen and the back part may be used.

  When the absorbent article is a pants-type disposable diaper, the exterior sheet preferably has a pants shape. That is, the exterior sheet has a front abdomen, a back part, and a crotch part positioned therebetween, and the front abdomen and the back part are joined to form a waist opening and a pair of leg openings. It is preferable. In addition, the front abdomen means a part applied to the wearer's abdomen when wearing a diaper, and similarly, the back part means a part applied to the wearer's buttocks, and the crotch is It means the part that hits the wearer's crotch.

  The absorbent article of the present invention is not limited to the embodiment shown in the drawings, and can be applied to general disposable absorbent articles such as urine pads, disposable diapers, and sanitary napkins.
