Description

  The present invention relates to a disposable absorbent article for children, adults or incontinence.

  Conventionally, as a disposable absorbent article such as a disposable diaper of this type, a configuration in which an absorber is disposed between a top sheet and a back sheet is common. In such a configuration, liquid excreta such as urine passes through the top sheet and is absorbed by the absorbent body, but solid stool and the like cannot be absorbed. And although it cannot absorb if it is excrement, such as solid stool, since it does not move in the said disposable absorbent article, it is hard to leak out from this disposable absorbent article. However, viscous excrement such as loose stool is difficult to permeate the top sheet, and therefore cannot be absorbed by the absorbent body and spreads in the disposable absorbent article. Accordingly, there is a risk of leakage to the outside, and excrement comes into contact with a wide area of the wearer's skin, and the wearing feeling is deteriorated.

Therefore, as a structure with good excrement such as viscous loose stool that does not come into contact with the skin of the wearer and has a good wearing feeling, between the surface layer as the top sheet and the leak-proof layer as the back sheet An absorbent layer as an absorber is interposed, and a pair of water-repellent outer three-dimensional gathers are formed on both sides in the width direction of the absorbent layer and on both sides in the width direction of the surface layer. There is known one in which a pair of water-repellent inner three-dimensional gathers protrudes at the formation interval. In this configuration, first, excrement is absorbed by an absorption interval formed between the pair of inner solid gathers, and further, an auxiliary absorption formed between the outer surface of the inner solid gathers and the outer surface of the outer solid gathers. Since the body fluid that leaked from the absorption interval is absorbed by the interval, the excrement is less likely to spread and the excrement is less likely to contact the wearer's skin (see, for example, Patent Document 1).
Japanese Utility Model Laid-Open No. 4-99921 (pages 1, 2 and 1-3)

  However, both ends in the longitudinal direction of the pair of inner solid gathers in Patent Document 1 described above are connected and the surface of the surface layer is covered like a bag, that is, an opening is formed on the surface on the wearer side. In the configuration, it is necessary to form the opening with the inner three-dimensional gather, and a step of hollowing out the opening in manufacturing is required. Therefore, the manufacturing becomes complicated, and further, the hollowed-out portion becomes garbage. There may be a problem.

  In addition, in the configuration in which the pair of inner solid gathers in Patent Document 1 are arranged in parallel with an absorption interval, although manufacture is easy, excrement such as loose stool flows and leaks in the longitudinal direction of the surface layer. There is a fear.

  This invention is made | formed in view of such a point, and provides the disposable absorbent article which is hard to leak excretion and is hard to contact a wearer's skin, and can be manufactured easily.

  The disposable absorbent article according to claim 1 is provided with a top sheet positioned on the wearer side, a back sheet positioned on the outer surface side, and an absorbent body positioned between the top sheet and the back sheet. The absorbent article main body has a portion where the topsheet and the absorber are not joined to each other at least in the center in the longitudinal direction and the center in the width direction, and the topsheet Is formed with a length shorter than the length of the topsheet in the longitudinal direction, the cutout portion communicating with the portion where the topsheet and the absorber are not joined, and the topsheet on both sides in the width direction of the cutout portion. An elastic body that is disposed along the longitudinal direction and opens the cut portion by contraction, and the elastic body is formed to have a longer length in the longitudinal direction than the cut portion, and both end portions in the longitudinal direction are Before both ends of the notch In which is located outside the longitudinal direction of the surface sheet.

  The disposable absorbent article according to claim 2 is the disposable absorbent article according to claim 1, wherein the top sheet is located on the wearer side, and the top sheet is located on the absorber side. The elastic body is formed between the upper surface sheet and the lower surface sheet. The lower surface sheet has a shorter length in the width direction.

  The disposable absorbent article according to claim 3 is the disposable absorbent article according to claim 1 or 2, wherein the top sheet is formed with a plurality of cut portions, and the width direction of each of the cut portions is Elastic bodies are provided on both sides.

  The disposable absorbent article according to claim 4 is the disposable absorbent article according to any one of claims 1 to 3, wherein the absorbent article body is liquid permeable between the top sheet and the absorbent body. An intermediate sheet is disposed, and has a portion where the top sheet and the intermediate sheet are not joined to each other at least in the center in the longitudinal direction and the center in the width direction.

  The disposable absorbent article according to claim 5 is the disposable absorbent article according to any one of claims 1 to 4, wherein at least a part of the absorbent body includes gauze, crepe paper, and a pulp layer. These are sequentially arranged from the top sheet side.

  According to the invention described in claim 1, the absorbent article main body has a portion in which the topsheet and the absorbent body are not joined at least in the central portion in the longitudinal direction and the central portion in the width direction, and the surface Since the sheet has the cut portion and the elastic body disposed on both sides in the width direction of the cut portion, the waste can be accommodated from the cut portion opened by the contraction of the elastic body. It is difficult for the absorbent article main body to leak out and excrement in the absorbent article main body is difficult to contact the wearer's skin.

  Moreover, since it is not necessary to cut and form an opening part only by forming a notch part in the said surface sheet, it can manufacture easily.

  According to the invention described in claim 2, the top sheet is formed of the upper surface sheet and the lower surface sheet, and the elastic body is disposed between the upper surface sheet and the lower surface sheet. Therefore, the elastic body can be easily disposed, and the entire elastic body can be reliably bonded to the top sheet.

  According to the invention described in claim 3, since a plurality of cut portions are formed and elastic bodies are arranged on both sides in the width direction of each cut portion, excrement is discharged from the cut portions. It can be reliably accommodated.

  According to the invention described in claim 4, by disposing the liquid-permeable intermediate sheet between the top sheet and the absorber, the absorber is exposed from the cut portion in the open state. Since the excrement can be diffused by the intermediate sheet, the excrement can be reliably held in the absorbent article body.

  According to the invention described in claim 5, liquid or viscous liquid excretion is provided by arranging gauze, crepe paper, and a pulp layer sequentially from the surface sheet side on at least a part of the absorber. Since the substance is difficult to flow by the gauze and the absorbent capacity can be improved by the crepe paper having a large surface area, leakage of the excrement from the absorbent article main body can be more reliably prevented.

  The configuration of the first embodiment of the present invention will be described in detail below with reference to FIGS.

  1 and 2 show a disposable absorbent article 1 in an unfolded state. This disposable absorbent article 1 is disposed on the wearer side of a pants-type absorbent article such as a diaper, for example, as an inner part. used.

  The disposable absorbent article 1 includes an absorbent article body 2 having a substantially rectangular shape. The absorbent article main body 2 includes a substantially rectangular top sheet 3 positioned on the wearer side, a substantially rectangular back sheet 4 positioned on the outer surface, and the surfaces when the disposable absorbent article 1 is mounted. A substantially rectangular absorbent body 5 located between the sheet 3 and the back sheet 4 is provided. A substantially rectangular intermediate sheet 6 is disposed between the top sheet 3 and the absorber 5. When the disposable absorbent article 1 is attached to the absorbent article body 2, the front side part 7 located on the abdomen side of the wearer, the center part in the longitudinal direction of the absorbent article body 2, and the wearer's inseam The crotch part 8 located on the rear side and the rear side part 9 located on the buttocks side of the wearer are sequentially formed along the longitudinal direction.

  The top sheet 3 and the back sheet 4 are joined so as to seal the absorbent body 5 and the intermediate sheet 6 between the top sheet 3 and the back sheet 4. Part or whole is joined. Furthermore, the top sheet 3 and the intermediate sheet 6 are not joined at least in the center part in the longitudinal direction, that is, the part corresponding to the crotch part 8 and the center part in the width direction, and other parts are joined. As shown in FIG. 3 and FIG. 4, in the disposable absorbent article 1 in use, a portion where the topsheet 3 and the intermediate sheet 6 are not joined becomes the accommodation pocket portion 10.

  When the disposable absorbent article 1 is worn, the top sheet 3 is located on the wearer's side and the pair of top sheets 13 located on the absorbent body 5 side and shorter in the width direction than the top surface sheet 13. The lower surface sheet 14 is formed. The pair of lower surface sheets 14 are joined to the upper surface sheet 13 so as to be separated from each other in the center portion in the width direction of the surface sheet 3.

  The upper surface sheet 13 and the lower surface sheet 14 are liquid-permeable and breathable and have a feeling close to underwear. For example, the upper surface sheet 13 and the lower surface sheet 14 are formed of a sheet material such as a woven fabric, a nonwoven fabric, a porous film, or a synthetic fiber. . Forming with such a sheet material is preferable because it allows liquid excretion such as urine to permeate and does not cause discomfort even when directly in contact with the body.

  The topsheet 3 having such a configuration includes a topsheet in the center portion in the width direction of the top topsheet 13, that is, the center portion in the width direction of the topsheet 3 in which the pair of bottom topsheets 14 are separated from each other. A linear cut portion 15 formed shorter than the length in the longitudinal direction of 3 is provided. The cut portion 15 is provided by cutting the surface sheet 3 from the front side portion 7 to the rear side portion 9 along the longitudinal direction of the surface sheet 3, and the surface sheet 3 and the intermediate sheet 6 are joined. There is no part, that is, the accommodation pocket portion 10 of the disposable absorbent article 1 in use.

  In addition, the elastic body 16 extends from the front side portion 7 to the rear side portion 9 between the upper surface sheet 13 and the lower surface sheet 14 on both sides of the cut portion 15 in the width direction of the surface sheet 3. It is disposed substantially parallel to the notch 15. The elastic body 16 is formed so that the length in the longitudinal direction is longer than that of the cut portion 15, and both end portions in the longitudinal direction are positioned outside the both end portions of the cut portion 15 in the longitudinal direction of the topsheet 3. It is installed. The elastic body 16 may be anything that can be expanded and contracted, and for example, string-like rubber or the like is used. In addition, it is preferable to make the color of the elastic body 16 different from that of the top sheet 3 because the cut portion 15 is easily noticeable.

  When the disposable absorbent article 1 is changed from the developed state to the use state in which the elastic body 16 is contracted, the cut portion 15 is opened by the contraction of the elastic body 16 and the topsheet 3 and the intermediate sheet 6 are not joined. A storage pocket portion 10 is formed at the portion.

  Here, the elastic body 16 is not disposed at the cut edge portion of the topsheet 3 formed by the cut portion 15, but is disposed outside the cut edge portion in the width direction of the topsheet 3. Thus, a flap portion 17 is formed between the cut edge portion and the elastic body 16. By forming the flap portion 17, as shown in FIG. 5, the flap portion 17 can be bent outward in the width direction of the topsheet 3 by the contraction of the elastic body 16, and the notch portion 15 is opened. Cheap.

  Note that if the length in the width direction of the flap portion 17 becomes too long, it becomes difficult to open the cut portion 15 due to the contraction of the elastic body 16, so the length a in the width direction of the flap portion 17 shown in FIG. It is preferable to form the flap part 17 so that it may become shorter than the distance b of the inner side edge part of the junction part in the surface sheet 3, and the elastic body 16. FIG.

  The back sheet 4 is formed in a film shape with a sheet material that is liquid-impervious or hydrophobic, such as polyethylene, and has moisture permeability. By being formed of such a sheet material, leakage of liquid excrement from the absorbent article main body 2 can be prevented by the back sheet 4. The back sheet 4 has a length in the longitudinal direction equivalent to that of the top sheet 3, and a length in the width direction is longer than that of the top sheet 3.

  The intermediate sheet 6 may be the same material as the top sheet 3, but is preferably formed of a material having liquid absorbency in addition to liquid permeability. In this case, since the liquid excrement can be absorbed also by the intermediate sheet 6 while the liquid excretion is permeated to the absorbent body 5, the absorbent capacity of the disposable absorbent article 1 is improved. The intermediate sheet 6 has a length in the longitudinal direction equivalent to that of the top sheet 3 and the back sheet 4, and ends in the longitudinal direction are joined so as to be sandwiched between the top sheet 3 and the back sheet 4. ing. Further, the length of the intermediate sheet 6 in the width direction is shorter than that of the top sheet 3 and is disposed so as to cover the entire absorbent body 5 with the intermediate sheet 6. Both end portions in the width direction of 5 are covered with the surface sheet 3.

  At both ends in the width direction of the absorbent article body 2, that is, at both ends in the width direction of the top sheet 3 and the back sheet 4, a liquid-impermeable gather sheet 18 along the longitudinal direction of the absorbent article body 2. The end portions in the width direction are joined. The gather sheet 18 has a first gather elastic body 19 disposed at the tip end on the other end side of the joined end portion, and a second gather elastic body 20 between the gather sheet 18 and the back sheet 4. Is arranged. The gather sheet 18, the first gather elastic body 19, and the second gather elastic body 20 form a three-dimensional gather 21. The three-dimensional gather 21 can rise with respect to the absorbent article main body 2 due to the contraction of the first gather elastic body 19 and the second gather elastic body 20 when the disposable absorbent article 1 is mounted. Acts as a leak barrier.

  Note that, in the first embodiment, for example, the absorbent sheet body 2 has a configuration in which the topsheet 3 and the intermediate sheet 6 are not joined at least at the crotch 8 and the center in the width direction. The front side pocket 7 and the rear side pocket 9 are formed in the disposable absorbent article 1 in the used state without joining the top sheet 3 and the intermediate sheet 6 at the front side 7 and the rear side 9 of the article body 2. You may make it the structure to perform. This configuration is preferable because viscous liquid excrement such as loose stool flows into the front storage pocket part and the rear storage pocket part and easily stores the excrement. However, if the size of the portion where the topsheet 3 and the intermediate sheet 6 are not joined is larger than the absorbent body 5, the excrement may not be absorbed by the absorbent body 5, so the topsheet 3 and the intermediate sheet 6 It is preferable that the storage pocket portion 10 in a state in which the absorbent body 5 is not joined, that is, in the use state, is located inside the absorbent article main body 2 from the portion where the absorbent body 5 is disposed.

  Moreover, although the surface sheet 3 was set as the structure where the length of the width direction was shorter than the back surface sheet 4, it is not limited to such a structure, The length of the width direction of the surface sheet 3 and the back surface sheet 4 is equivalent. It is good.

  Furthermore, although the surface sheet 3 is configured by the upper surface sheet 13 and the lower surface sheet 14, the surface sheet 3 is not limited to such a configuration, and the surface sheet 3 is configured by a single sheet material. Also good. In the case of such a configuration, the cut edge located at the center in the width direction of the top sheet 3 is folded back outward in the width direction, and the elastic body 16 is disposed between the folded portion and the top sheet 3. The structure which performs is considered. In this configuration, since the length in the longitudinal direction of the cut portion 15 is shorter than the length in the longitudinal direction of the elastic body 16, the length in the longitudinal direction of the folded portion is shorter than that of the elastic body 16, resulting in elasticity. Both ends of the body 16 in the longitudinal direction cannot be reliably disposed. Therefore, a configuration in which the top sheet 3 is formed by the upper surface sheet 13 and the lower surface sheet 14 and the elastic body 16 is disposed between the upper surface sheet 13 and the lower surface sheet 14 is preferable.

  When the top sheet 3 is formed by the upper surface sheet 13 and the lower surface sheet 14, the configuration is not limited to the configuration in which the pair of lower surface sheets 14 are separated from each other at the center in the width direction of the top sheet 3. As shown in FIG. 6, the pair of lower surface sheets 14 may not be separated from each other. In the case of this configuration, one lower surface sheet 14 is disposed at the center of the upper surface sheet 13 in the width direction, and the upper surface sheet 13 and the lower surface sheet 14 are cut into a linear shape and cut portions Form 15.

  In the absorbent article main body 2, an intermediate sheet 6 is disposed between the top sheet 3 and the absorbent body 5, and in the disposable absorbent article 1 in use, the storage pocket portion 10 is provided between the top sheet 3 and the intermediate sheet 6. However, the present invention is not limited to such a configuration, and the intermediate sheet 6 may not be provided. In the case of a configuration in which the intermediate sheet 6 is not provided, the topsheet 3 and the absorbent body 5 are joined at least at a portion corresponding to the crotch portion 8 and a portion other than the central portion in the width direction, and the disposable absorbent article 1 in use. Then, the accommodation pocket part 10 is formed in the part to which the surface sheet 3 and the absorber 5 are not joined.

  Moreover, in the structure which provides the intermediate sheet 6, it is not limited to the structure which covers the absorber 5 whole with the intermediate sheet 6, For example, the center of the width direction of the absorber 5 located on the extension line of the notch part 15 is provided. It is good also as a structure etc. which arrange | position the intermediate sheet 6 only to a part, and cover the other part of the absorber 5 with the surface sheet 3.

  The cut portion 15 is configured to be provided from the front side portion 7 to the rear side portion 9, but is not limited to such a configuration and may be formed at least in the crotch portion 8.

  Moreover, the notch part 15 is not limited to the structure formed in the center part of the width direction of the absorbent article main body 2 along the longitudinal direction of the absorbent article main body 2, For example, the absorbent article main body 2 The structure etc. which form on an inclination with respect to the longitudinal direction of this may be sufficient.

  Furthermore, the cut part 15 is not limited to the structure which cut | disconnected the surface sheet 3 completely, The cut part 15 should just be cut | disconnected and opened in the use condition of the disposable absorbent article 1, For example, the portion 15 may be formed in a chain line shape such as a perforation, and the chain line cut portion 15 may be cut when used.

  It is preferable that the elastic body 16 is disposed substantially parallel to the cut portion 15, so that the cut portion 15 is easily opened by contraction of the elastic body 16, but the invention is not limited to such a configuration, and the cut portion 15 and the elastic body 16 need not be parallel.

  Although the three-dimensional gathers 21 are provided along the longitudinal direction at both ends of the absorbent article main body 2 in the width direction, the present invention is not limited to such a configuration, and the three-dimensional gathers 21 may be provided.

  Next, the operation and effect of the first embodiment will be described.

  When the disposable absorbent article 1 is mounted, the disposable absorbent article 1 is stored in a folded state. Therefore, the folded disposable absorbent article 1 is expanded, and the elastic body 16 and the first gather elasticity are expanded. The body 19 and the second gather elastic body 20 are in a contracted state of use.

  Here, in the disposable absorbent article 1 in use, the notch 15 is opened by the contraction of the elastic body 16, and the accommodation pocket 10 is formed at the portion where the topsheet 3 and the intermediate sheet 6 are not joined. Then, the three-dimensional gather 21 is raised by the contraction of the first gather elastic body 19 and the second gather elastic body 20.

  Next, for example, a pants-type disposable absorbent article such as a diaper is placed so that the open cut portion 15 of the disposable absorbent article 1 and the accommodation pocket portion 10 communicating with the cut portion 15 are located in the crotch of the wearer. The disposable absorbent article 1 is disposed inside.

  Then, the pants-type disposable absorbent article provided with the disposable absorbent article 1 is mounted so that the flap portions 17 located on both sides of the cut portion 15 in the width direction come into contact with the wearer's crotch.

  When such a disposable absorbent article 1 is worn, the excrement of the wearer enters and is accommodated into the accommodation pocket portion 10 through the opened cut portion 15.

  Here, if the excrement flowing into the storage pocket portion 10 is a liquid excrement such as urine, it is diffused by the intermediate sheet 6 and transmitted through the intermediate sheet 6 and absorbed by the absorber 5. If the excrement that has flowed into the storage pocket 10 is a liquid excrement having a viscosity such as soft stool, it is difficult to be absorbed by the absorber 5, but is diffused by the intermediate sheet 6 in the storage pocket 10. If the excrement that has entered the storage pocket 10 is a solid excrement such as solid stool, the solid excretion is difficult to move in the storage pocket 10, so that it is stored in the storage pocket 10. Retained.

  Thus, according to the disposable absorbent article 1, the absorbent article main body 2 has a portion in which the topsheet 3 and the absorbent body 5 are not joined to the center portion in the longitudinal direction and the center portion in the width direction, The surface sheet 3 is used by having a cut portion 15 communicating with a portion where the surface sheet 3 and the intermediate sheet 6 are not joined, and elastic bodies 16 disposed on both sides of the cut portion 15 in the width direction. In the state, the notch 15 is opened by the contraction of the elastic body 16, and the accommodation pocket 10 is formed at a portion where the topsheet 3 and the absorber 5 are not joined. Then, excrement enters from the opened cut portion 15 into the accommodation pocket portion 10, and the excrement can be accommodated in the accommodation pocket portion 10. Therefore, even if the excrement cannot be absorbed by the absorbent body 5, the excrement is difficult to leak out from the absorbent article main body 2 since the state accommodated in the accommodation pocket portion 10 can be maintained. Furthermore, since the accommodation pocket part 10 is located in the absorber 5 side from the surface sheet 3, the excretion accommodated in the accommodation pocket part 10 is hard to contact a wearer's skin, and a wearing feeling is hard to deteriorate. In this embodiment, since the intermediate sheet 6 is disposed between the top sheet 3 and the absorber 5, the storage pocket portion 10 is provided between the top sheet 3 and the intermediate sheet 6 in use. However, the storage pocket 10 is formed between the top sheet 3 and the absorbent body 5 when the intermediate sheet 6 is not disposed. Even if the intermediate sheet 6 is not provided, the same effect as described above can be obtained by the cut portion 15 and the accommodation pocket portion 10.

  Further, the disposable absorbent article 1 has a surface sheet 3 at a portion other than the central part in the longitudinal direction and the central part in the width direction of the absorbent article main body 2 even when compared with the manufacture of the disposable absorbent article having a conventional configuration. And the intermediate sheet 6 are joined, a notch 15 is formed along the longitudinal direction at the center in the width direction of the surface sheet 3 in the unfolded state, and elastic bodies 16 are disposed on both sides of the notch 15. Can only be manufactured. Moreover, since it is not necessary to cut out and form the opening part only by forming the linear cut part 15 in the surface sheet 3, it can manufacture easily and can reduce the dust at the time of manufacture.

  Since the top sheet 3 is formed of the upper surface sheet 13 and the lower surface sheet 14, and the elastic body 16 is disposed between the upper surface sheet 13 and the lower surface sheet 14, the elastic body 16 is disposed. When installing, the upper surface sheet 13 and the lower surface sheet 14 may be joined so as to sandwich the elastic body 16, the elastic body 16 can be easily disposed, and the entire elastic body 16 is entirely disposed on the surface sheet 3. Can be securely joined.

  Here, when the upper surface sheet 13 and the lower surface sheet 14 are joined, the pair of lower surface sheets 14 are joined apart from each other at the center in the width direction of the surface sheet 3, By providing the notch 15 in the part where the surface sheet 14 is separated, the notch edge formed by the notch 15 that is easy to contact the wearer is only the upper surface sheet 13, so it becomes too hard There is nothing and the touch is good.

  On the other hand, when the upper surface sheet 13 and the lower surface sheet 14 are joined, the pair of lower surface sheets 14 are not separated from each other, and a single sheet of the lower surface sheet 14 is provided at the center in the width direction of the upper surface sheet 13. When the cut portions 15 are formed in the upper surface sheet 13 and the lower surface sheet 14, the pair of lower surface sheets 14 are separated from each other and are easier than the structure in which the upper surface sheet 13 is joined to each other. In addition, the position where the cut portion 15 is formed and the position where the elastic body 16 is disposed may be slightly shifted in the width direction of the top sheet 3, and molding defects due to manufacturing errors are unlikely to occur. Further, the boundary between the upper surface sheet 13 and the lower surface sheet 14 is difficult to understand, and the appearance of the cut portion 15 is improved.

  Furthermore, since the flap portion 17 is formed at the cut edge portion of the top sheet 3, the cut portion 15 easily opens due to the contraction of the elastic body 16, and the flap portion 17 comes into contact with the wearer. The adhesiveness of the property article 1 can be improved, and the excrement can be easily stored in the storage pocket portion 10.

  In addition, the elastic body 16 is formed in a color different from that of other parts such as the top sheet 3 or a mark is provided in the vicinity of the notch 15 so that the disposable absorbent article 1 is cut when worn. Since the portion 15 is easily noticeable, the disposable absorbent article 1 can be easily attached accurately.

  Furthermore, by providing the cut portion 15 and the elastic body 16 substantially in parallel, the cut portion 15 can be easily opened due to the contraction of the elastic body 16, so that excrement can be reliably transferred from the cut portion 15 to the storage pocket portion 10. Can be accommodated.

  By disposing the liquid-permeable intermediate sheet 6 between the top sheet 3 and the absorbent body 5, it is possible to prevent the absorbent body 5 from being exposed from the notch 15 in the open state, so that excrement is absorbed. By exposing the absorbent body 5 from the notch 15, it is possible to prevent excrement absorbed by the absorbent body 5 from leaking out from the storage pocket section 10. Further, since the excrement flowing into the accommodation pocket portion 10 from the cut portion 15 can be diffused by the intermediate sheet 6, it is possible to prevent the excretion from leaking out from the accommodation pocket portion 10. Therefore, excrement can be reliably held in the absorbent article body 2.

  Next, a second embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 7 to 9, a plurality of, for example, two notches 15 are formed in the topsheet 3 along the longitudinal direction. In use, each of the notches 15 has an accommodation pocket 10. Communicating with

  In addition, elastic bodies 16 are disposed on both sides of each cut portion 15 in the width direction, and two elastic bodies 16 are disposed between the two cut portions 15. By the contraction of these elastic bodies 16, the two cut portions 15 are opened.

  Then, the two cut portions 15 are formed in the surface sheet 3, and the elastic bodies 16 are disposed on both sides of the respective cut portions 15 in the width direction. The insert 15 can be opened reliably. Therefore, the excrement can be reliably stored in the storage pocket portion 10 from the two opened cut portions 15. Further, even if the mounting position of the disposable absorbent article 1 is shifted, the accommodation pocket portion can be removed from one of the two cut portions 15 by providing two cut portions 15. Since the excrement can be accommodated in 10, the excrement can be easily accommodated in the accommodation pocket portion 10.

  Here, as described above, in the configuration in which a plurality of, for example, two incisions 15 are formed in the topsheet 3, as shown in FIGS. 10 and 11, one elastic is provided between the two incisions 15. The body 16 may be arranged.

  Further, as shown in FIG. 10, in the configuration in which the three lower surface sheets 14 are separated and joined to the upper surface sheet 13, the incision edge formed in each incision portion 15 is not too hard, Although it is preferable because it feels good, it is necessary to join the three lower surface sheets 14 to the upper surface sheet 13 and form the cut portions 15 between the lower surface sheets 14, so that the manufacturing is complicated. Become.

  On the other hand, as shown in FIG. 11, in the configuration in which the lower surface sheet 14 is not separated, one lower surface sheet 14 is joined to the upper surface sheet 13, and a plurality of upper surface sheets 13 and the lower surface sheet 14 are bonded to each other. Since it is only necessary to form the notch 15, it can be easily manufactured as compared with the configuration of FIG. 10, and molding defects due to manufacturing errors are less likely to occur.

  In addition, in this embodiment, it was set as the structure which formed the two cut parts 15 in the surface sheet 3, However, The number of the cut parts 15 formed in the surface sheet 3 is not limited to two, It can set suitably.

  Further, in the case of the configuration in which the two elastic bodies 16 are disposed between the two cut portions 15, the lower surface sheet 14 is not separated, but is not limited to such a configuration, The three lower surface sheets 14 may be separated from each other and joined to the upper surface sheet 13.

  Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 12, the absorbent body 5 is formed by sequentially arranging a gauze 23, a crepe paper 24, and a pulp layer 25 from the surface sheet 3 side.

  In the absorbent body 5 having such a configuration, the liquid or viscous liquid excrement accommodated in the accommodation pocket portion 10 from the notch portion 15 first enters the eyes of the gauze 23 and is contained in the accommodation pocket portion 10. It becomes difficult to flow. Next, the excrement that has passed through the gauze 23 is absorbed by the crepe paper 24. However, the crepe paper having a large surface area that has a large number of wrinkles has a large area that can be absorbed, so that the absorbency can be improved. Further, since the pulp layer 25 is disposed on the back sheet 4 side of the crepe paper 24, the excrement from the absorbent article body 2 is surely absorbed, and the excrement from the absorbent article body 2 is absorbed. Leakage can be prevented more reliably.

For example, the gauze 23 preferably has a number of warps 12 ± 1 of 40 cotton yarns and 12 ± 1 cotton yarns of 1 ± ² cm ² , but is not limited to such a configuration. However, if the number of warp and weft yarns is increased and the gauze 23 is clogged, it becomes difficult for feces and other excrement to enter and the flow suppression effect deteriorates. Less is preferable.

  The crepe paper 24 is a paper on which a large number of wrinkles are formed, and the surface area is increased by forming the wrinkles. A plurality of the crepe papers 24 are superposed and arranged.

  The pulp layer 25 is formed by laminating flap pulp.

  In addition, it is preferable to dispose an absorbent sheet (not shown) formed of, for example, a polymer absorbent (SAP) between the crepe paper 24 and the pulp layer 25 because the absorbent capacity of the absorbent body 5 is further improved. .

  In addition, in the structure using such an absorber 5, since the excrement such as loose stool is less likely to flow by the gauze 23, the intermediate sheet 6 is not disposed.

  In this embodiment, the entire absorbent body 5 is formed by the gauze 23, the crepe paper 24, and the pulp layer 25. However, the present invention is not limited to this structure, and at least a part of the absorbent body 5 is used. It is sufficient that the gauze 23, the crepe paper 24, and the pulp layer 25 are provided.
