Description

  The present invention relates to an absorbent article used by being applied to a wearer's crotch. Specifically, the present invention relates to an absorbent article suitable for being used by being sandwiched between the crotch of a wearer who is in a lateral or semi-sideward position.

  DESCRIPTION OF RELATED ART Conventionally, the absorbent article of the type used on an inner surface, such as a disposable diaper for adults and underwear, is known. Such an absorbent article is called a urine absorbing pad or an absorbent pad. The urine absorbing pad is formed in a planar shape having a front body that covers the abdomen of the wearer, a back body that covers the back of the wearer, and a crotch part that is positioned between them and abuts the crotch of the wearer It is common (patent document 1 etc.).

  Moreover, in the field of care, when a caregiver applies a urine collecting pad to the wearer's (cared person's) inseam, the urine collecting pad is folded in the length direction, and the cross section of the urine collecting pad is W-shaped. In some cases, the wearer's crotch is sandwiched (see FIG. 49). Folding in a W shape makes it easier to absorb urine because the central convex portion of W comes into contact with the genitals. Moreover, when a wearer is a man, the device which makes the urine picking pad U shape and abuts so that a penis may fit in the bottom of U and guides the excretion direction of urine is also performed.

  By the way, some wearers have symptoms such as paralysis and joint contracture, cannot sleep in a supine posture, and can only take a lateral or semi-recumbent posture. As shown in FIG. 50, when lying in the lying position or half-side-down position, both legs remain tightly closed, so the urine collection pad sandwiches between the wearer's legs. There is a need. However, if the urine collection pad is folded in a W shape or U shape and sandwiched between the urine collection pad and the wearer's crotch, a gap is formed between the urine collection pad and the wearer's crotch, and urine leakage is likely to occur from the gap. (See FIG. 49).

  Further, as shown in FIG. 49, a normal urine absorbing pad 300 has a structure in which an absorber 303 is interposed between a liquid-permeable top sheet 301 and a liquid-impermeable back sheet 302. In this case, when the urine collecting pad 300 is folded into a W shape, the liquid-impermeable back sheet 302 comes into contact with the inner thighs of the wearer's legs. However, if the liquid-impermeable back sheet 302 is in contact with the inner thigh, the urine flowing along the inner thigh cannot be absorbed by the urine absorbing pad. There was a problem that urine was likely to leak from between. In addition, if the liquid-impermeable back sheet 302 keeps in contact with the wearer's skin, it may cause a skin trouble.

  Therefore, the present invention can fit without causing a gap in the inseam of the wearer who takes a lateral or semi-recumbent posture, and appropriately absorbs body fluid flowing along the inner thigh and externally absorbs it. An object is to provide an absorbent article capable of preventing leakage.

  As a result of intensive studies on the means for solving the above problems, the inventor of the present invention faces an absorbent main body configured to include an absorbent body toward the top surface portion that comes into contact with the wearer's inseam and the non-skin facing surface side. Thus, a three-dimensional shape having left and right side portions and a space formed between both side portions is provided. As a result, the inventor appropriately fits the urine flowing along the inner thigh while the absorbent main body having the above-mentioned three-dimensional shape fits the inseam of the wearer who assumes the posture of the lateral recumbent position or the half recumbent position. And obtained knowledge that it can be prevented from leaking outside. Then, the inventor has conceived that the problems of the prior art can be solved based on the above knowledge, and completed the present invention. Specifically, the present invention has the following configuration.

  The present invention relates to an absorbent article such as a urine absorbing pad. The absorbent article according to the present invention includes an absorbent main body 10. The absorptive main body 10 includes a plurality of sheet members and an absorber disposed between the plurality of sheet members. The absorptive main body 10 includes a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and left and right side surface portions 2 and 3 extending from the top surface portion toward the skin non-facing surface side of the top surface portion 1. Have. In the absorbent main body 10, a space is formed between the left and right side portions 2 and 3.

  Like the said structure, since the top | upper surface part 1 of the absorptive main body 10 closely_contact | adheres to a wearer's crotch, the excreted bodily fluid can be first absorbed by the top | upper surface part 1. FIG. Further, since the left and right side surfaces 2 and 3 of the absorbent main body 10 are in close contact with the inner thigh from the base of the wearer's leg in a lateral or semi-recumbent position, the inner thigh is routed. The body fluid flowing through can be effectively absorbed. Furthermore, since the absorbent article does not need to be folded into a W shape or U shape like a conventional urine collecting pad, the wearer's skin does not come into contact with unevenness, and there is little mechanical irritation to the skin. That's it.

  In the absorbent article according to the present invention, it is preferable that a liquid-impermeable leak-proof sheet 20 is attached to part of the left and right side portions 2 and 3 of the absorbent main body 10.

  As in the above configuration, the liquid impermeable leak-proof sheet 20 is attached to the side surface parts 2 and 3, so that the body fluid that has permeated the side surface parts 2 and 3 reaches the leak-proof sheet 20 and stays there. Therefore, the body fluid can be prevented from oozing out. Thereby, the underwear and disposable diaper which accumulated this absorptive article are not polluted. Moreover, since the leak-proof sheet 20 can be grasped and pulled out when exchanging the absorbent article, the absorbent article can be exchanged without dirtying hands.

  In the absorbent article according to the present invention, the leak-proof sheet 20 is attached to the lower end portion 5 on the opposite side of the top surface portion 1 of the left and right side surface portions 2 and 3 across the left and right side surface portions 2 and 3. It is preferable that In this case, the left and right side surface portions 2 and 3 may have a liquid absorbing portion 6 to which the leakage preventing sheet 20 is not attached between the lower end portion 5 to which the leakage preventing sheet 20 is attached and the top surface portion 1. preferable.

  As the above configuration, the leakproof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3, so that the body fluid leakage preventing effect is enhanced and the leakproof sheet 20 is grasped to absorb the absorbent article. It will be easier to replace. Moreover, the body fluid which flows along an inner thigh can be more reliably absorbed by providing the liquid absorption part 6 in the side parts 2 and 3 on either side.

  In the absorbent article according to the present invention, the top surface portion 1 is preferably formed with a through hole 7 connected to the space 4. This “through hole” may be a simple cut or an opening having a circular or polygonal area. Further, the “through hole” may be one in which both ends are closed, one having one end reaching the end of the top surface portion 1, or both ends being the ends of the top surface portion 1. The crack which reached the part may be sufficient.

  By providing the through hole 7 in the top surface portion 1 as described above, body fluid can be guided into the space 4 of the absorbent main body 10 through the through hole 7. Thereby, even if a large amount of body fluid is excreted at a time, it can be efficiently absorbed. Moreover, when a wearer is a man, the excretion direction of urine can be guided by inserting a penis into the through-hole 7. FIG.

  In the absorbent article according to the present invention, the top surface portion 1 and the left and right side surface portions 2 and 3 are continuously connected, and a mountain fold line 8 is formed as a boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3. Preferably it is. The “mountain crease” is a crease that is convex when viewed from the outer surface side of the absorbent article.

  By forming the mountain fold line 8 on the boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3 as in the above configuration, the surface that contacts the skin of the top surface portion 1 can be made substantially flat. it can. Thereby, the fitting property of the top | upper surface part 1 and a wearer's inseam improves. Moreover, since the space 4 formed between the side surface portions 2 and 3 is not easily crushed, the fit between the side surface portions 2 and 3 and the inner thigh of the wearer is also improved.

  In the absorbent article according to the present invention, it is preferable that a valley crease 9 is further formed between the top surface portion 1 and the leak-proof sheet 20 on either or both of the left and right side surface portions 2 and 3. The “valley fold” is a fold opposite to the aforementioned mountain fold, and is a fold that is concave when viewed from the outer surface side of the absorbent article.

  By forming the valley crease 9 in addition to the mountain crease 8 as described above, the absorbent article can be folded with the top surface portion 1 lying down. For this reason, it becomes easy to accommodate an absorbent article in a package. Moreover, in the state which accommodated the absorbent article in the package, since it is not necessary to make a crease in the top surface part 1, the top surface part 1 can be maintained flat. Thereby, the absorbent article can be used immediately after being taken out of the package. Thus, it is preferable that the top surface portion 1 is basically a flat surface with no folds formed.

  In the absorbent article of the present invention, the leak-proof sheet 20 may include a fixing portion 21 joined to the left and right side portions 2 and 3 and an extending portion 22 extending from the fixing portion 21. In this case, it is preferable that the extending portion 22 has a length that can cover the top surface portion 1.

  As in the above configuration, the leak-proof sheet 20 has the extended portion 22, so that, for example, when the absorbent article is used, the top surface portion 1 can be covered with the extended portion 22 of the leak-proof sheet 20. it can. Since the top surface portion 1 is a portion that directly touches the wearer's crotch, the hygienic state can be maintained by covering this portion with the extending portion 22.

  Another aspect of the present invention relates to a product in which a plurality of absorbent articles 100 according to the first aspect are accommodated in the package 200. As for the product concerning the present invention, it is preferred that a plurality of absorptive articles 100 are stored in package 200 in the state where it was folded in mountain crease 8 and valley crease 9.

  Like the said structure, the mountain fold 8 and the valley crease 9 are formed in each of the absorbent article 100, and it folds along these creases | folds 8 and 9, and the some absorbent article 100 of the package 200 is carried out. It can be stored compactly inside. Moreover, the top | upper surface part 1 of the absorbent article 100 can be maintained in a flat state by folding in this way. That is, even if it does not crease the top surface portion 1 of the absorbent article 100, it can be accommodated in the package 200.

  In the absorbent article according to the present invention, it is preferable that the absorbent body 13 further has one or a plurality of first pressing lines 31 extending in the width direction on the top surface portion 1.

  Like the said structure, the stress of the top surface part 1 with respect to the external force added from the width direction can be heightened by forming the 1st pressing line 31 extended in the width direction in the top surface part 1 of the absorber 13. FIG. Thereby, the absorptive main body 10 becomes easier to adhere to the wearer's crotch and inner thigh, and the space 4 between the left and right side portions 2 and 3 can also be held. Moreover, the body fluid which touched the top surface part 1 becomes easy to spread | diffuse in the width direction by forming the 1st pressing line 31 extended in the width direction in the top surface part 1 of the absorber 13. FIG. Thereby, since a bodily fluid can be rapidly absorbed in the wide range from the top | upper surface part 1 to the side parts 2 and 3, the urine leak prevention effect can be heightened.

  In the present invention, it is preferable that the absorbent body 13 has a boundary between the top surface portion 1 and the left and right side surface portions 2 and 3 by a second pressing line 32 extending in the depth direction. More specifically, the top surface portion 1 and the left and right side surface portions 2 and 3 are continuously connected to each other, and the absorber 13 is connected to the absorber 13 at a position corresponding to the boundary between the top surface portion 1 and the left and right side surface portions 2 and 3. The pressing line 32 is formed. For this reason, this 2nd pressing line 32 functions as a mountain fold which divides the top | upper surface part 1 and the side parts 2 and 3 on either side.

  Like the said structure, it becomes easy to hold | maintain the shape of the top | upper surface part 1 by forming the 2nd pressing line 32 in the boundary of the top | upper surface part 1 and the side parts 2 and 3 on either side. Thereby, since the top | upper surface part 1 closely_contact | adheres to a wearer's crotch, urine leakage can be prevented effectively.

  In this invention, it is preferable that the 2nd pressing line 32 is formed in the circular arc shape projected toward the outer side of the width direction.

  Like the said structure, by making it the circular arc shape which protrudes the 2nd pressing line 32 toward the outer side of the width direction, the front-and-rear both-ends side of the depth direction of the top | upper surface part 1 stands | starts up, and a wearer's crotch lower abdomen Because it is shaped along the buttocks, it is easy to fit without gaps. Thereby, it is possible to more effectively prevent excreted urine and feces from leaking.

  In this invention, it is preferable that the absorber 13 has the 1 or several 3rd pressing line 33 extended in the depth direction in the left-right side parts 2 and 3. As shown in FIG.

  Like the said structure, the stress with respect to the external force of the depth direction added to this absorber 13 can be heightened by forming the 3rd pressing line 33 extended in the depth direction in the right-and-left side part 2 and 3 of the absorber 13. it can. Moreover, the space 4 between the left and right side surfaces 2 and 3 can be held by forming the third pressing wire 33.

  In the present invention, the absorber 13 may be formed by laminating the main absorber 13 and the sub absorber 14 in the thickness direction at least on the top surface portion 1. In this case, the 1st pressing line 31 should just be formed in both the main absorber 13 and the sub absorber 14, or any one.

  The absorption amount in this top surface part 1 can be increased by making the absorber which comprises the top surface part 1 into the two-layer structure of the main absorber 13 and the subabsorber 14 like the said structure. Furthermore, since the thickness of the absorber of the top surface portion 1 is increased and the rigidity is high, the top surface portion 1 is not easily crushed in the width direction or deformed. The main absorber 13 may be positioned on the top surface portion 1 and the left and right side surface portions 2 and 3, and the sub-absorber 14 may be positioned only on the top surface portion 1. Thereby, it becomes easy to bend the right and left side surface parts 2 and 3 at the boundary with the top surface part 1, and as a result, it becomes easy to maintain the three-dimensional shape of the absorbent article having the space 4 inside.

  In this invention, it is preferable that the through-hole 7 connected to the space 4 is formed in the top | upper surface part 1 in which the 1st pressing line 31 was formed.

  In the present invention, as described above, by providing one or a plurality of first pressing lines 31 extending in the width direction on the top surface portion 1, the rigidity in the width direction of the top surface portion 1 is increased to prevent the deformation of the shape. . For this reason, even when the through-hole 7 is provided in the top surface part 1, the through-hole 7 is hard to block | close and can exhibit the function as a hole. Further, by providing the sub-absorber 14 on the top surface portion 1 to form a two-layer structure, the rigidity is further increased in the width direction, and the blocking of the through hole 7 can be prevented.

  In the absorbent article according to the present invention, the absorbent main body 10 is preferably connected to the lower ends of the left and right side portions 2 and 3. Furthermore, it is preferable that lattice-shaped pressing lines 41 are formed on the absorbent body 13 located on the top surface portion 1 of the absorbent article. The “lattice shape” as used herein means a state in which a plurality of pressing lines extending in a certain direction intersect with a plurality of pressing lines extending in a different direction. For example, the “grid shape” includes a rhombic lattice shape and a square lattice shape. Moreover, the pressing line 41 is formed by pressing the absorbent body 13 from one or both of the skin facing surface side and the skin non-facing surface side, and the absorbent body 13 is recessed along the pressing line 41. Will be formed. In addition, the grid | compression-like pressing wire 41 should just be formed in the top | upper surface part 1 of the absorber 13, and may be formed in the side parts 2 and 3 on either side, and is formed in the absorber 13 whole. It may be.

  Like the said structure, the stress of the top | upper surface part 1 with respect to the external force added from the width direction of an absorbent article can be heightened especially by forming the grid | lattice-like pressing wire 41 in the top | upper surface part 1 of the absorber 13. FIG. Thereby, since the top | upper surface part 1 of the absorptive main body 10 becomes difficult to be crushed, it becomes easy to adhere to a wearer's inseam and inner thigh, and the space 4 between the left and right side parts 2 and 3 can also be held. . Moreover, by forming the grid-like pressing lines 41 on the top surface portion 1 of the absorbent body 13, body fluids that have touched the top surface portion 1 are likely to diffuse along the pressing lines 41. Thereby, since a bodily fluid can be rapidly absorbed in the wide range from the top | upper surface part 1 to the side parts 2 and 3, the urine leak prevention effect can be heightened.

  In the present invention, the grid-like pressing lines 41 include those extending along the width direction of the absorbent article or extending along a direction inclined in the range of 1 degree to 45 degrees with respect to the width direction. It is preferable that

  Like the said structure, the stress of the top | upper surface part 1 with respect to the external force added to the width direction is included in the grid-like pressing line 41 by the line extended along the width direction, or the line extended inclined at 45 degrees or less. Can be increased more effectively.

  In the absorbent article of the present invention, the leak-proof sheet 20 is attached to the lower end portion 5 on the opposite side to the top surface portion 1 of the left and right side surface portions 2 and 3 across the left and right side surface portions 2 and 3. Preferably it is. The leakproof sheet 20 connects the lower ends of the left and right side surface portions 2 and 3. Furthermore, it is preferable that the left and right side surface portions 2 and 3 have a liquid absorbing portion 6 to which the leakage preventing sheet 20 is not attached between the lower end portion 5 to which the leakage preventing sheet 20 is attached and the top surface portion 1.

  As in the above configuration, the liquid impermeable leakproof sheet 20 is attached to the side surface parts 2 and 3, so that the body fluid that has penetrated into the side surface parts 2 and 3 reaches the leakproof sheet 20 and stays there. Thus, it can be prevented from exuding to the outside. Thereby, the underwear and disposable diaper which accumulated this absorptive article are not polluted. Further, when the absorbent article is replaced, it is only necessary to grasp the leak-proof sheet 20 and pull it out, so that the absorbent article can be replaced without dirtying the hands. Furthermore, by providing the left and right side surface portions 2 and 3 with the liquid absorbing portion 6 without the leak-proof sheet 20, the body fluid flowing along the inner thigh can be more reliably absorbed.

  In this invention, it is preferable that the absorptive main body 10 further has the subabsorber 14 which overlapped with the absorber 13 (main absorber) on the top | upper surface part 1 in the thickness direction. In this case, each of the absorbent body 13 and the secondary absorbent body 14 includes a plurality of pressing lines 41 and 51, and each pressing line 41 and 51 is at least partially intersected when viewed from the plane direction. preferable.

  Like the said structure, the absorption amount in a top | upper surface part can be raised by laminating | stacking and arrange | positioning the two absorbers 13 and 14 in the thickness direction. Moreover, the diffusibility of a bodily fluid can be improved by forming the pressing lines 41 and 51 in each absorber 13,14. And by arrange | positioning each absorber 13 and 14 so that a mutual compression line 41 and 51 may cross | intersect, a bodily fluid can be effectively osmose | permeated also to the area | region (non-compression area | region) in which the compression line is not formed. It becomes possible. That is, the body fluid diffused along the squeezing line of one absorber is easily absorbed by the non-compressed region of the other absorber. For this reason, the bodily fluid which spread | diffused along the pressing line of one absorber becomes difficult to reach an edge part, and the situation which leaks outside can be prevented effectively. Moreover, since it becomes possible to absorb body fluid in a wide range of the two-layer absorbers 13 and 14, the amount of body fluid absorbed is improved, and it is difficult for the wearer to feel uncomfortable even when worn for a long time. .

  In the present invention, the absorbent body 13 and the secondary absorbent body 14 are respectively a plurality of non-squeezed regions 42 and 52 surrounded by the squeezing lines 41 and 51 and a plurality of intersection parts 43 where the squeezing lines 41 and 51 intersect. , 53. Furthermore, it is preferable that at least a part of one intersection of the absorbent body 13 and the secondary absorbent body 14 overlaps the other non-compressed region.

  Like the said structure, since the pressing lines 41 and 51 cross | intersect in the intersection parts 43 and 53 formed in each absorber 13 and 14, a bodily fluid tends to stay. Therefore, by overlapping the intersection part of this one absorbent body on the non-compressed area of the other absorbent body, it is possible to effectively infiltrate the body fluid staying at the intersection part into the non-compressed area. Thereby, body fluids such as urine excreted in the top surface portion 1 can be quickly diffused by efficiently using both the two-layer absorbers 13 and 14.

  In the present invention, the top surface portion 1 is preferably formed with a through hole 7 connected to the space 4. In particular, the through-hole 7 is preferably formed in a region of the top surface portion 1 where the grid-like pressing lines 41 are formed.

  As described above, in the present invention, by providing the grid-like pressing wires 41 on the top surface portion 1, it is possible to increase the rigidity in the width direction of the top surface portion 1 and prevent the deformation of the shape. Therefore, even when the through-hole 7 is provided in the top surface portion 1, the through-hole 7 is difficult to close and the function as a hole can be exhibited. Further, by providing the top surface portion 1 with the main absorbent body 13 and the secondary absorbent body 14 to form a two-layer structure, the rigidity is further increased in the width direction, and the through hole 7 can be prevented from being blocked.

  In the absorbent article according to the present invention, a plurality of squeezed wires 41 may be formed on the absorbent body 13 located on the left and right side portions 2 and 3.

  The plurality of squeezing lines 41 are preferably a plurality of parallel squeezing lines, a plurality of squeezing lines defining a closed area, or a plurality of parallel squeezing lines defining a closed area. Moreover, the pressing line 41 may be formed in the grid | lattice form. The “lattice shape” as used herein means a state in which a plurality of pressing lines extending in a certain direction intersect with a plurality of pressing lines extending in a different direction. For example, the “grid shape” includes a rhombic lattice shape and a square lattice shape. Moreover, the pressing line 41 is formed by pressing the absorbent body 13 from one or both of the skin facing surface side and the skin non-facing surface side, and the absorbent body 13 is recessed along the pressing line 41. Will be formed. In addition, the several pressing line 41 should just be formed in the side parts 2 and 3 on either side of the absorber 13 at least, may be formed in the top | upper surface part 1, and is formed in the absorber 13 whole. May be.

  Like the said structure, the body fluid adhering or osmose | permeated to this side part can be spread | diffused in a wide range by forming the several pressing wire 41 in the side parts 2 and 3 of the absorber 13. FIG. Thereby, since the bodily fluid can be absorbed with the whole absorber 13, the bodily fluid which flows along an inner thigh can be appropriately absorbed with the absorber 13, and it can prevent effectively that a bodily fluid leaks outside. Moreover, the stress of the side surface parts 2 and 3 with respect to the external force added to an absorptive thing can be raised by forming the several pressing wire 41 in the side surface parts 2 and 3 of the absorber 13. FIG. Thereby, since the side surface parts 2 and 3 of the absorptive main body 10 become difficult to be crushed, it becomes easy to adhere more closely to a wearer's inner thigh.

  In the absorbent article of the present invention, the leak-proof sheet 20 is attached to the lower end portion 5 on the opposite side to the top surface portion 1 of the left and right side surface portions 2 and 3 across the left and right side surface portions 2 and 3. Preferably it is. The leakproof sheet 20 connects the lower ends of the left and right side surface portions 2 and 3. Furthermore, it is preferable that the left and right side surface portions 2 and 3 have a liquid absorbing portion 6 to which the leakage preventing sheet 20 is not attached between the lower end portion 5 to which the leakage preventing sheet 20 is attached and the top surface portion 1.

  As in the above configuration, the liquid impermeable leakproof sheet 20 is attached to the side surface parts 2 and 3, so that the body fluid that has penetrated into the side surface parts 2 and 3 reaches the leakproof sheet 20 and stays there. Thus, it can be prevented from exuding to the outside. Thereby, the underwear and disposable diaper which accumulated this absorptive article are not polluted. Further, when the absorbent article is replaced, it is only necessary to grasp the leak-proof sheet 20 and pull it out, so that the absorbent article can be replaced without dirtying the hands. Furthermore, by providing the left and right side surface portions 2 and 3 with the liquid absorbing portion 6 without the leak-proof sheet 20, the body fluid flowing along the inner thigh can be more reliably absorbed.

  In the absorbent article of the present invention, the pressing wire 41 is preferably formed on the absorbent body 13 located in the liquid absorption part 6.

  Like the said structure, it can avoid that this pressing line 41 is hidden in the back side of the leak-proof sheet 20 by providing the pressing part 41 in the liquid absorption part 6. FIG. Thereby, the bodily fluid adhering to or penetrating the liquid absorption part 6 is diffused in a wide range along the pressing line 41.

  In the absorbent article of the present invention, the pressing wire 41 is preferably formed on the absorbent body 13 from the liquid absorbing portion 6 to the lower end portion 5 to which the leakproof sheet 20 is attached.

  Like the said structure, the squeeze line 41 is provided so that it may connect from the liquid absorption part 6 to the lower end part 5, Therefore The bodily fluid absorbed with the liquid absorption part 6 of the leak-proof sheet 20 through the squeeze line 41 is provided. It is possible to quickly lead to the lower end portion 5 hidden behind. Since the lower end portion 5 is hidden behind the leak-proof sheet 20, the body fluid hardly penetrates into the lower end portion 5, but the squeezed wire 41 functions as a flow path for carrying the body fluid to the lower end portion 5. Thereby, a bodily fluid can be diffused in a wider range.

  In the absorbent article of the present invention, the absorbent main body 10 may further include a secondary absorbent body 14 that overlaps the absorbent body 13 in the thickness direction on the left and right side surfaces 2 and 3. In this case, it is preferable that the squeezed wire 51 is also formed in the auxiliary absorbent body 14. Furthermore, the squeezing line 41 of the absorbent body 13 and the squeezing line 51 of the auxiliary absorbent body 14 are preferably at least partially intersecting.

  In the left and right side surface portions 2 and 3 as in the above configuration, in addition to the absorber 13 (hereinafter also referred to as “main absorber”) constituting the top surface portion 1 and the left and right side surface portions 2 and 3, The amount of liquid absorbed by the side surfaces 2 and 3 is increased by overlapping the auxiliary absorbers 14 on the side surfaces 2 and 3. Thereby, even when a large amount of body fluid is excreted, leakage of urine can be prevented. Moreover, the compression line 41,51 is formed in both the main absorber 13 and the subabsorber 14, and these compression lines 41 and 51 are made to cross | intersect into the area | region (non-squeeze area | region) in which the compression line is not formed. It is possible to effectively infiltrate the body fluid. Therefore, the body fluid diffused along the squeezing line of one absorber is easily absorbed by the non-compressed region of the other absorber, and the body fluid can be diffused over a wider range.

  The absorbent article according to the present invention can be fitted without creating a gap in the crotch of a wearer who is in a lateral or semi-side-down position, and appropriately absorbs body fluid flowing along the inner thigh. Can be prevented from leaking outside.

[1. First Embodiment]
With reference to FIGS. 1-5, 1st Embodiment of the absorbent article 100 which concerns on this invention is described. FIG. 1 is a perspective view showing an outline of an absorbent article 100 according to the present invention. As FIG. 1 shows, the absorbent article 100 which concerns on this invention has comprised the cylindrical three-dimensional shape which has the space 4 inside. In the present embodiment, the back surfaces of both ends of one planar rectangular absorbent main body 10 are formed in a cylindrical shape having a space 4 extending along the depth direction (D) with the palms aligned. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and left and right side surface portions 2 extending from the left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (the left side surface portion 2 and the right side surface portion 3) and a space 4 formed between the left and right side surface portions 2 and 3. This space 4 penetrates along the depth direction (D) from the wearer's ventral end to the dorsal end. Furthermore, a liquid-impermeable leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3 of the absorbent main body 10. The leak-proof sheet 20 is joined across the left and right side portions 2 and 3, and also has a function of connecting the side portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed in the top surface portion 1 of the absorbent main body 10.

  Then, each element which comprises the absorbent article 100 is demonstrated concretely. 2 shows an exploded perspective view of the absorbent article 100, and FIG. 3 shows a cross-sectional view of the absorbent article. As shown in FIGS. 2 and 3, the absorbent article 100 includes an absorbent main body 10 and a leak-proof sheet 20 attached to the lower part thereof.

  The absorptive main body 10 is an element for absorbing and holding body fluid excreted from the wearer's crotch. The absorptive main body 10 has a configuration in which an absorber 13 is interposed between a plurality of sheet members. Specifically, the absorbent main body 10 includes an outer sheet 11 that constitutes an outer surface (skin facing surface) of the absorbent article 100, an inner sheet 12 that constitutes an inner surface (skin non-facing surface) of the absorbent article 100, and And an absorber 13 disposed between the two sheets 11 and 12. In the present embodiment, the outer sheet 11, the inner sheet 12, and the absorber 13 are molded in a rectangular shape. However, the shape of the outer sheet 11, the inner sheet 12, and the absorber 13 is not limited to a rectangular shape, and may be a circle, an ellipse, or other polygonal shapes. Further, the outer sheet 11 and the inner sheet 12 have a length and width that are slightly larger than those of the absorber 13, and surround the periphery of the absorber 13, so that a known adhesive, heat fusion, or ultrasonic wave is used. Joined by fusion. For this reason, the absorber 13 will be in the state enclosed with the inside of the outer surface sheet | seat 11 and the inner surface sheet | seat 12 which the circumference | surroundings were joined.

  The outer sheet 11 is a sheet-like member that directly contacts the wearer's skin and allows body fluid such as urine to pass through the absorber 13. For this reason, the outer sheet 11 is made of a liquid-permeable material having high flexibility. Examples of the liquid permeable material constituting the outer sheet 11 are a woven fabric, a non-woven fabric, or a porous film. Moreover, as the outer sheet | seat 11, it is good also as using the thing which made the nonwoven fabric by hydrophilizing the fiber of thermoplastic resins, such as a polypropylene, polyethylene, polyester, nylon, for example. Examples of the nonwoven fabric include air-through nonwoven fabric, point bond nonwoven fabric, spunbond nonwoven fabric, and melt blown nonwoven fabric.

  Although the inner sheet 12 does not directly contact the wearer's skin, the inner sheet 12 is formed of a material that can transmit the body fluid introduced into the space 4 through the through hole 7 of the top surface 1 to the absorber 13. Is preferred. For this reason, like the outer sheet 11, the inner sheet 12 is preferably made of a liquid-permeable material having high flexibility. Examples of the liquid permeable material are as described above. However, the inner surface sheet 12 does not necessarily need to be formed with a liquid-permeable material, and may be formed with a liquid-impermeable material. An example of the liquid-impermeable material is a plastic film made of polyethylene resin. In particular, when the inner surface sheet 12 is formed of a liquid-impermeable sheet member, a microporous polyethylene film having a plurality of fine pores of 0.1 to 4 μm is used to ensure air permeability. Is preferred.

  The absorber 13 is a member for absorbing body fluid such as urine and holding the absorbed body fluid. The absorber 13 is disposed between the outer sheet 11 and the inner sheet 12. Moreover, as will be described later, the absorber 13 disposed in the outer sheet 11 and the inner sheet 12 is not limited to one layer, and may be two or more layers. Further, the absorber 13 is bonded to both or one of the outer sheet 11 and the inner sheet 12 by a hot melt adhesive or the like so that the position does not shift between the outer sheet 11 and the inner sheet 12. Also good. The absorber 13 is basically composed of an absorbent material 13a and a core wrap sheet 13b covering the absorbent material 13a. As the absorbent material 13a, for example, fluff pulp obtained by pulverizing a fiber material such as softwood or hardwood, a superabsorbent polymer (SAP), or a hydrophilic sheet may be used. Moreover, as the absorptive material 13a, you may use individually 1 type among a fluff pulp, a super absorbent polymer, or a hydrophilic sheet | seat, and it can also use together in combination of 2 or more types. Generally, the absorptive material 13a is comprised by what spread | dispersed the super absorbent polymer in the fluff pulp. The core wrap sheet 13b is a sheet member for holding the shape by covering the absorbent material 13a. As the core wrap sheet 13b, a sheet member having liquid permeability is used. As an example of the core wrap sheet 13b, a thin paper such as tissue paper or a known nonwoven fabric can be used.

  The leak-proof sheet 20 is a sheet member for preventing body fluid absorbed by the absorbent main body 10 from leaking outside. The leak-proof sheet 20 can also be used as a handle when the absorbent article 100 that has absorbed body fluid is pulled out of the wearer's crotch. For this reason, the leak-proof sheet 20 is attached to at least a part of the outer surfaces of the left and right side portions 2 and 3 of the absorbent main body 10. Specifically, the leak-proof sheet 20 is preferably attached to the outer surfaces of the lower end portions 5 of the left and right side portions 2 and 3 of the absorbent main body 10. The leak-proof sheet 20 is made of a liquid-impermeable material in order to prevent body fluid from leaking out. An example of the liquid-impermeable material is a plastic film made of polyethylene resin as described above. In particular, in order to ensure air permeability while maintaining liquid impermeability, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed.

  From the unfolded state as shown in FIG. 2, the outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together to form the absorbent main body 10, and both left and right ends of the absorbent main body 10 in the width direction (W). Is bent toward the inner sheet 12 side, and its lower end is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 provided with the absorptive main body 10 and the leak-proof sheet 20 becomes a cylindrical three-dimensional shape as shown in FIG. Furthermore, as shown in FIG. 3, the leak-proof sheet 20 is attached across the left side surface portion 2 and the right side surface portion 3 at the lower end portion 5 of the absorbent main body 10. For this reason, it can be said that the leak-proof sheet 20 has a function of connecting the left side surface portion 2 and the right side surface portion 3 of the absorbent main body 10.

  In the example shown in FIG. 3, the absorbent main body 10 has a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and extends from the left and right sides of the top surface portion 1 toward the skin non-facing surface side. The left and right side surfaces 2 and 3 are integrally connected. A mountain fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3. Thereby, the cross section of the absorptive main body 10 becomes an approximately inverted triangle. Moreover, although the top surface part 1 will be located between the right-and-left mountain folds 8, this top surface part 1 is a substantially flat surface. Thus, by making the top surface portion 1 a flat surface without making a crease, the top surface portion 1 can easily adhere to the wearer's crotch. In addition, as FIG. 3 shows, it is preferable that the length B of the width direction (W) of the top | upper surface part 1 is 20 mm-150 mm, for example, and it is especially preferable that it is 30 mm-100 mm.

  Moreover, as FIG. 3 shows, the left-right side parts 2 and 3 are respectively the lower end part 5 which is the area | region where the leak-proof sheet 20 was joined, and the top | upper surface part 1 (mountain crease 8) from this lower end part 5. It is divided into the liquid absorption part 6 which is a region up to. The leakage preventing sheet 20 is not joined to the liquid absorption part 6. For this reason, the left and right side surface portions 2 and 3 can absorb body fluid from the outer surface side in the liquid absorbing portion 6. When the absorbent article 100 is sandwiched between the crotch of the wearer who is in the lateral or semi-sided position and the top surface portion 1 is brought into contact with the crotch of the wearer, the left and right side portions 2 and 3 are both legs of the wearer. It touches the inner thigh. For this reason, it is possible to effectively absorb the body fluid flowing along the wearer's inner thigh by forming the liquid absorbing portion 6 capable of absorbing the body fluid from the outer surface side on the left and right side surface portions 2 and 3. It becomes. In addition, it is preferable that it is 20 mm-200 mm, for example, and the length T of the height direction (H) of the liquid absorption part 6 is 50 mm-150 mm. The left and right side surface portions 2 and 3 may be bonded to each other with a hot melt adhesive or the like at the lower end portion (the end portion on the side where the leak-proof sheet 20 is disposed).

  As shown in FIGS. 1 to 3, a through hole 7 is formed in the top surface portion 1 of the absorbent main body 10, and body fluid is introduced into the space 4 through the through hole 7. Yes. For this reason, as shown in FIG. 2, the through hole 7 is formed in all of the outer surface sheet 11, the inner surface sheet 12, and the absorber 13 constituting the top surface portion 1. The through hole 7 is preferably formed in an elongated shape extending along the depth direction (D) of the absorbent main body 10. The shape of the through hole 7 is not particularly limited, but may be a substantially hexagonal shape, a square shape, or an elliptical shape as shown in FIG. The through hole 7 may be a simple cut. The through-hole 7 may have a slit shape with one end reaching the front end or the rear end of the absorbent main body 10, or both ends have a crack shape with the front end and the rear end of the absorbent main body 10. It may be. Thus, by forming the through-hole 7, the excreted body fluid can be transmitted to the absorber 13 not only from the outer sheet 11 side but also from the inner sheet 12 side. For this reason, even when a large amount of body fluid is excreted at once, urine leakage can be effectively prevented. Furthermore, when the wearer is a man, the urinary excretion direction can be guided or fixed by inserting the penis into the through-hole 7.

  FIG. 4 shows an example of a state in which the absorbent article 100 is sandwiched between the crotch of the wearer. As shown in FIG. 4, in the absorbent main body 10, the top surface portion 1 that forms a flat surface is in close contact with the inseam of the wearer, and the side surface portions 2 and 3 that are positioned on the left and right sides thereof are on the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side surface portions 2 and 3, the absorbent main body 10 has a high cushioning property as a whole, and the state of close contact with the crotch and the inner thigh is maintained. Thereby, it becomes difficult to produce a clearance gap between the absorptive main body 10 and a wearer's skin, and even when it is a case where it mounts | wears with the wearer who is taking the attitude | position of a lateral position or a half lateral position, It is possible to effectively prevent urine leakage from the side surfaces 2 and 3 side. Furthermore, since the leak-proof sheet 20 is attached to the lower end portion 5 of the absorbent main body 10, it is possible to avoid contamination of underwear, sheets, or disposable diapers mounted in layers. Further, when the absorbent article 100 is replaced, the replacement work can be easily completed without making the hands dirty by pulling out the leak-proof sheet 20 with the handle.

  As described above, since the absorbent article 100 of the present invention is assumed to be used by being sandwiched between the wearer's crotch, the front body and the back part covering the abdomen of the wearer like a conventional urine collecting pad There is no need to cover the back. For this reason, as FIG. 1 shows, the length L of the whole depth direction (D) of the absorbent article 100 of this invention should just be 80 mm-250 mm, or 100 mm-200 mm. According to the present invention, such a compact absorbent article can be realized.

  Fig.5 (a) to FIG.5 (e) has shown the example of the manufacturing process of the absorbent article 100 which concerns on 1st Embodiment. FIG. 5 shows a cross-sectional view along the line V-V together with each drawing. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 5 (a) to 5 (e). That is, first, a rectangular outer sheet 11 is prepared (FIG. 5A). In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this time. Next, the rectangular absorbent body 13 in which the through-holes 7 are formed is placed on the skin non-facing surface side of the outer sheet 11, and the inner sheet 12 is placed on the skin non-facing surface side of the absorbent body 13. (FIG. 5B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. In addition, you may join the absorber 13 to both the outer surface sheet 11 and the inner surface sheet 12, or any one. Thereby, the absorptive main body 10 is obtained. In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this stage. Next, the absorbent main body 10 is folded in two along the through-hole 7 formed in the absorbent body 13 toward the inner surface sheet 12 side (FIG. 5C). That is, the sheet is folded in half so that the outer sheet 11 is on the outer side and the inner sheet 12 is on the inner side. At this time, the through hole 7 of the absorber 13 is positioned at the top of the fold. Thereafter, the apex portion where the through-hole 7 of the absorber 13 is located is cut off, and the through-hole 7 having substantially the same shape as the absorber 13 is also formed in the outer sheet 11 and the inner sheet 12 (FIG. 5D). At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are also substantially simultaneously cut off at the same position as the through hole 7 of the absorber 13. The through hole 7 can be formed. Then, the leak-proof sheet 20 is joined to the position corresponding to the lower end part of the absorptive main body 10 (FIG.5 (e)). In addition, you may add the process of forming the mountain fold 8 (or valley crease 9 mentioned later) in the appropriate position of the absorptive main body 10 which comprises the absorbent article 100. FIG. Moreover, you may add the process of adhere | attaching the edge part (namely, edge part by which the leak-proof sheet | seat 20 is arrange | positioned) on the opposite side to the half-folded vertex with a hot-melt-adhesive etc.

  By following said manufacturing process, the absorbent article 100 in which the through-hole 7 was formed can be manufactured efficiently. Further, as shown in FIG. 5 (c), after the through hole 7 is formed in the absorber 13, the entire absorbent main body 10 is folded in two along the through hole 7. The folds attached to the top surface portion 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 is a flat surface and no crease remains. However, the crease formed on the top surface portion 1 is minimized by forming the crease that is unavoidably generated during the manufacturing process along the through hole 7. Can be limited. Thereby, it is also possible to make a state in which almost no creases remain on the top surface portion 1 at the time of wearing.

In the case of this example, a mountain fold line 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3. For this reason, the top surface portion 1 forms a flat surface. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3.

  FIG. 12B shows an example in which the cross-sectional shape of the absorbent main body 10 is substantially T-shaped. In the case of this example, a mountain fold 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2, 3, and a valley fold is formed at a position corresponding to the liquid absorbing portion 6 of the left and right side surface portions 2, 3. 9 is formed. In the region below the valley crease 9, the left and right side surface portions 2 and 3 are in contact with each other and extend straight. In the region where the left and right side surface portions 2 and 3 abut, in order to keep the space 4 between the left and right side surface portions 2 and 3 wide, it is preferable not to join the two. However, it is also possible to join the portions where the left and right side surface portions 2 and 3 abut with a hot melt adhesive or the like. The leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3. Such a substantially T-shaped absorbent main body 10 can be compactly stored without folding on the flat top surface portion 1 by folding along the mountain fold line 8 and the valley fold line 9.

  FIG.12 (c) has shown the example from which the cross-sectional shape of the absorptive main body 10 becomes a substantially water drop shape. In the case of this example, the absorbent main body 10 is not formed with folds (mountain folds and valley folds), is bent using the flexibility of the absorbent main body 10, and both left and right end portions are leak-proof sheets. 20 is bound. For this reason, the top | upper surface part 1 with the surface which contacts a wearer's crotch among the absorptive main bodies 10 has expanded as a whole toward the wearer's skin side, and FIG. 12 (a) and FIG. It does not have a flat surface as in the example shown in b). Note that, as in the example shown in FIG. 12C, when no crease is formed as a boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3, the width of the absorbent main body 10 in the natural state. What is necessary is just to divide the area | region to the site | part which becomes the maximum width in a direction as the top | upper surface part 1. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3. Such a waterdrop-shaped absorbent main body 10 has a merit that it has a high cushioning property and has no irregularities, and thus has a good touch and hardly gives mechanical irritation to the wearer's skin.

  FIG. 12D shows an example in which the cross-sectional shape of the absorbent main body 10 is substantially circular at the top and is substantially rectangular at the bottom. In the case of this example, valley folds 9 are formed in the liquid absorbing portions 6 of the left and right side surface portions 2 and 3 in the absorbent main body 10. In the region above the valley crease 9, no crease is formed, it is curved using the flexibility of the absorbent main body 10, and has a substantially circular cross section. For this reason, the top | upper surface part 1 of the absorptive main body 10 has expanded as a whole toward the wearer's skin side, and does not have a flat surface. On the other hand, in the region below the valley crease 9, the left and right side surface portions 2, 3 are in contact with each other and extend straight. The portions where the left and right side surface portions 2 and 3 abut can be joined by a hot melt adhesive or the like. Moreover, the part which the right and left side surface parts 2 and 3 contact functions as a handle when the absorbent article 100 is inserted into and removed from the wearer's crotch. For example, in the example shown in FIG. 12D, the leak-proof sheet 20 extends longer upward than in the other examples, making it easier to grip. The example shown in FIG. 12D can be said to be easy to use when it is necessary to locally apply the absorbent article 100 to a narrow part of the wearer's crotch.

  FIG. 13A shows an example in which the cross-sectional shape of the absorbent main body 10 is substantially circular. In this example, the absorbent main body 10 is completely cylindrical. Further, a leakproof sheet 20 is attached to a part of the outer surface of the absorbent main body 10. And the site | part which attached this leak-proof sheet 20 is made into the lower end part 5 of the right-and-left side parts 2 and 3, the site | part on the opposite side to this lower end part 5 is made into the top surface part 1, and the lower end part 5 and the top surface part 1 The area between them is referred to as a liquid absorption part 6.

  FIG. 13B shows an example in which the cross-sectional shape of the absorbent main body 10 is a substantially inverted Ω shape. In this example, the absorptive main body 10 has a top surface portion 1 having a surface that comes into contact with the crotch of the wearer and is divided into left and right at a crack 7 '. At the position corresponding to the split 7 ′ at the center in the width direction of the top surface portion 1, the left and right side surface portions 2 and 3 extend toward the skin non-facing surface side of the top surface portion 1. A space 4 is formed between the left and right side surface portions 2 and 3. The split 7 ′ of the top surface portion 1 communicates with the space 4 between the left and right side surface portions 2 and 3. For this reason, it can be said that this crack 7 'has a function similar to the through-hole 7 mentioned above. In addition, valley folds 9 are formed on the boundary lines between the top surface portion 1 and the left and right side surface portions 2 and 3, respectively. Further, the left and right side surface portions 2 and 3 are integrally connected at their lower ends, and a mountain fold line 8 (folding line) is formed on the boundary line between the left and right side surface portions 2 and 3. For this reason, the absorptive main body 10 is in a state where the bottom end portion is closed. In other words, the absorbent main body 10 is folded at the center in the width direction to form a mountain crease 8 (folding line), and further folded in the opposite direction on both the left and right sides in the width direction to form a valley fold 9. ing. In the example shown in FIG. 13B, the mutually facing surfaces of the left and right side surface portions 2 and 3 may be partially or entirely joined by a hot melt adhesive or the like, or may not be joined at all. Good. In particular, in order to introduce a body fluid into the space 4 through the split 7 ′ of the top surface portion 1 or insert a penis into the space 4 and use it, the opposing surfaces of the left and right side surface portions 2 and 3 should not be joined. Or, it is preferable to keep it partially joined. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3. At this time, the crease corresponding to the mountain crease 8 (folding line) on the boundary line between the left and right side surface portions 2 and 3 may also be formed in the leakproof sheet 20. In the example shown in FIG. 13B, even a solid material can be accommodated in the space 4 between the left and right side surfaces 2 and 3. For this reason, it can utilize suitably as a pad for accumulating and processing soft stool.

  FIG. 13C is a further modification of the example shown in FIG. In the example shown in FIG. 13C, the left side surface portion 2 and the right side surface portion 3 are separated at the lower end. That is, in this example, two absorptive main bodies 10 are used, the left top surface portion 1 and the left side surface portion 2 are formed by the first absorbent main body 10, and the right top surface portion 1 and the right side surface portion 3 are formed. Is formed by the second absorbent main body 10. The left side surface portion 2 of the first absorbent main body 10 and the right side surface portion 3 of the second absorbent main body 10 are connected to each other at the lower end portion 5 by a leak-proof sheet 20, and the two absorbent main bodies 10 are connected. The example shown in FIG. 13C is basically the same as the example shown in FIG. 13B except that the absorbent main body 10 is divided into two on the left and right.

  FIG. 14A shows an example in which one absorbent main body 10 is bent so that the absorbent main body 10 overlaps two layers in the top surface portion 1. That is, in this example, the absorbent main body 10 is overlapped in two layers on the top surface portion 1, the upper layer portion is integrally connected to the left side surface portion 2, and the lower layer portion is integrally connected to the right side surface portion 3. A mountain fold line 8 is formed on the boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3, and the top surface portion 1 has a substantially flat surface. Further, the left and right side surface portions 2 and 3 are integrally connected at the lower end, and a mountain fold line 8 is formed on the boundary line between them. For this reason, the cross section of the absorbent main body 10 is a substantially inverted triangle. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3. In the example shown in FIG. 14A, the absorbent main body 10 overlaps two layers on the top surface portion 1, so that the amount of body fluid absorbed on the top surface portion 1 can be increased.

  FIG. 14B shows an example in which the absorbent main body 10 constituting the top surface portion 1 and the absorbent main body 10 constituting the left and right side surface portions 2 and 3 are separately provided. In this example, the left and right side surface portions 2 and 3 are configured by a single absorbent main body 10, and the absorbent main body 10 is bent at a mountain crease 8 at the lower end to be substantially V-shaped. On the other hand, the absorbent main body 10 constituting the top surface portion 1 is bent toward the left and right sides and the inside in the width direction and overlapped on the outer surface side of the upper end portions of the left and right side portions 2 and 3, and this overlapping portion is adhesive or the like. Join with. The top surface portion 1 can be flat without a fold. In this way, the top surface portion 1 and the left and right side surface portions 2 and 3 can be configured by separate absorbent main bodies 10. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3.

  FIG. 14C shows an example in which one absorbent main body 10 is bent so that the absorbent main body 10 overlaps two layers at the lower end portion 5. That is, in this example, the top surface portion 1 and the left and right side surface portions 2 and 3 are integrally connected via the mountain fold line 8. On the other hand, the portion forming the left side surface portion 2 is folded inward at the lower end, and the portion forming the right side surface portion 3 is folded back inward at the lower end and partially overlaps the outer surface of the left side surface portion 2. . Thus, the lower end sides of the left and right side surface portions 2 and 3 can be folded back and overlapped in two layers. In this case, the amount of body fluid absorbed at the lower end 5 of the absorbent main body 10 can be increased. The leak-proof sheet 20 is attached across the side surface portions 2 and 3 at the lower end portions 5 of the left and right side surface portions 2 and 3.

  FIG. 14D shows an example in which one absorbent main body 10 is bent to have a substantially inverted triangular cross section, and the joint of the end of the absorbent main body 10 is positioned on the right side surface portion 3 (or the left side surface portion 2). Is shown. That is, in this example, the top surface portion 1 and the left and right side surface portions 2 and 3 are integrally connected via the mountain fold line 8. The left and right side surface portions 2 and 3 are also integrally connected at the lower end, and a mountain fold line 8 is formed on the boundary line. However, in this example, the seam at the end of the absorbent main body 10 is located on the right side surface portion 3. Therefore, a leak-proof sheet 20 is attached so as to cover the seam. For this reason, in this example, only the site | part equivalent to the right side surface part 3 of the absorptive main body 10 is attached to the leak-proof sheet 20. Thus, the leak-proof sheet 20 is not restricted to the lower end part of the absorptive main body 10, and should just be attached to at least one part of the outer surface of the absorptive main body 10. FIG.

  In addition, in the example shown in FIGS. 12-14, illustration of the through-hole 7 of the top | upper surface part 1 is abbreviate | omitted. Also in the example shown in FIGS. 12 to 14, the through hole 7 connected to the internal space 4 can be formed in the top surface portion 1 of the absorbent main body 10 as in the first to third embodiments described above. Is possible.

[5. Products containing absorbent articles]
FIG. 15 schematically shows an example of a product in which a plurality of absorbent articles 100 are accommodated in the package 200. In FIG. 15, the package 200 is conceptually drawn as having a rectangular parallelepiped or cubic internal space. As the package 200, a well-known package such as a bag or a box can be appropriately employed. Moreover, as the package 200, well-known things, such as paper, cloth, vinyl, and plastic, can be employed. As the package 200, any known one can be used without particular limitation as long as it has an internal space capable of accommodating at least two or more absorbent articles 100.

  FIG. 15A is an example of a product in which an absorbent article 100 (see FIG. 12B) in which the cross-sectional shape of the absorbent main body 10 is substantially T-shaped is accommodated in the package 200. As shown in FIG. 15 (a), each absorbent article 100 is folded at the left and right mountain folds 8 provided between the top surface portion 1 and the left and right side surface portions 2, 3 and provided on the left side surface portion 2. They are arranged in the package 200 in a state of being folded at the valley crease 9 formed. Thus, by arranging the absorbent article 100 in a state where the top surface portion 1 is laid sideways, it is not necessary to form a crease in each top surface portion 1 when accommodated in the package 200. Thereby, since the flat state of the top surface portion 1 is maintained, the top surface portion 1 is easily brought into contact with the wearer's crotch. Moreover, as shown in FIG. 15A, a plurality of absorbent articles 100 can be stored compactly in the package 200 by folding the absorbent article 100.

  FIG. 15B is an example of a product in which the absorbent article 100 (see FIG. 12A and the like) in which the cross-sectional shape of the absorbent main body 10 has a substantially inverted triangular shape is accommodated in the package 200. As shown in FIG. 15 (b), each absorbent article 100 is folded at the left and right mountain folds 8 provided between the top surface portion 1 and the left and right side surface portions 2 and 3. Furthermore, each absorbent article 100 has a valley fold 9 formed only on the left side surface 2 (or the right side surface 3) of the left and right side surfaces 2 and 3, and the valley fold 9 is also folded. As described above, also in the example shown in FIG. 15B, the top surface portion 1 of each absorbent article 100 is arranged in a laid-down state so that a crease is formed on each top surface portion 1 when accommodated in the package 200. It becomes unnecessary to form.

  FIG. 16 shows a modification of the absorbent article 100 at the time of accommodation in the package 200. In the example shown in FIG. 16, the leak-proof sheet 20 includes a fixing portion 21 that is non-detachably joined to the lower end portion 5 of the absorbent main body 10, and an extension that extends from one of the left and right ends of the fixing portion 21. And an exit portion 22. In a state where the absorbent main body 10 is folded so that the top surface portion 1 is laid down, the extension portion 22 of the leak-proof sheet 20 has an extension length that can cover the top surface portion 1 of the absorbent main body 10. It has become a thing. The extending portion 22 may be temporarily bonded to the top surface portion 1 or the side surface portions 2 and 3 so as to be partially peelable while covering the top surface portion 1. Thus, in the state accommodated in the package body 200, the sanitary state of the top surface portion 1 can be improved by covering the top surface portion 1 of the absorbent main body 10 with a part (extension portion 22) of the leak-proof sheet 20. Can keep. As shown in FIG. 16, the leak-proof sheet 20 has a perforation 23 formed between the fixing portion 21 and the extension portion 22, and the fixing portion 21 and the extension portion are formed along the perforation 23. 22 may be separated. The extended part 22 is not disturbed by separating the extended part 22 from the fixed part 21 and discarding it during use.

[6. Further modifications of absorbent articles]
FIG. 17 is a plan view showing a further modification of the absorbent article. 18 is a cross-sectional view schematically showing the cross-sectional shape of XVIII-XVIII shown in FIG.

  FIG. 17 shows a state in which the absorbent main body 10 is folded in the order of (a), (b), and (c), and finally the state shown in (c) is obtained. In the unfolded state shown in FIG. 17 (a), the absorbent main body 10 includes a front side portion 10a located on the front side (the wearer's stomach side) in the depth direction (D) and the rear side in the depth direction (D). It is divided into a rear side part 10b located on the wearer's back side and a central part 10c located between them. In the example shown in FIG. 17, when the entire length in the depth direction (D) of the absorbent main body 10 is 100%, the length of the central portion 10 c is about 10% to 50%, and the remaining The length portion is divided into a front side portion 10a and a rear side portion 10b. Moreover, the front side part 10a and the rear side part 10b of the absorptive main body 10 have a longer length in the width direction (W) than the central part 10c. In other words, the absorptive main body 10 has left and right flap portions 10L and 10R extending toward the left and right outer sides in the width direction (W) from the center portion 10c on both the front side portion 10a and the rear side portion 10b. Yes. For this reason, the absorptive main body 10 becomes a shape like a substantially hourglass shape in plan view. In the example shown in FIG. 17, the right flap R extends longer than the left flap L from the central portion 10 c toward the outside in the width direction (W).

  In addition, as shown in FIG. 17A, the absorbent body 13 of the absorbent main body 10 may have pressing lines 13c formed in a rhombic lattice pattern. The pressing line 13c is formed by pressing the absorbent body 13 from one or both of the skin facing surface side and the skin non-facing surface side, and the absorbent body 13 has a recess along the pressing line 13c. Will be formed. In addition, the rhombic lattice-shaped pattern intersects a plurality of squeezed lines 13c extending in a direction (oblique direction) inclined with respect to the depth direction (D) and the width direction (W) in a plan view. (Diamond) refers to the pattern in which the non-squeezed area is defined. In this way, by forming a plurality of pressing lines 13c in the absorbent body 13, the diffusibility of body fluids in contact with the surface of the absorbent body 13 can be enhanced, and the strength and shape retention of the entire absorbent main body 10 can be increased. Can be increased. In addition, although illustration is abbreviate | omitted, the compression line 13c can also be formed in the absorber 13 with a square grid | lattice-like pattern. The square lattice pattern here refers to a plurality of squeezing lines 13c extending in parallel to the depth direction and a plurality of squeezing lines 13c extending in parallel to the width direction, and a square (rectangular) non-squeezing region is defined. The pattern that is done.

  Next, as shown in FIG. 17 (b), the part of the absorbent main body 10 including the left flap portion 10L in the front side portion 10a and the rear side portion 10b is skinned toward the inner side in the width direction (W). Fold back to the opposite side. Then, as FIG.17 (c) shows, the site | part containing the right flap part 10R in the front side part 10a and the rear side part 10b among the absorptive main bodies 10 is skin facing toward the inner side of the width direction (W). Fold back to the side. At this time, the left flap portion 10L and the right flap portion 10R are vertically overlapped, and the overlapping portions are joined with a hot melt adhesive or the like. Then, as shown in FIG. 17 (c), in the central portion 10c of the absorbent main body 10, between the flap portions 10L and 10R of the front side portion 10a and the flap portions 10L and 10R of the rear side portion 10b, the through hole 7 Will be formed. The through hole 7 has a function corresponding to the through hole 7 in each of the embodiments described above.

  FIG. 18 shows a cross-sectional shape in the state shown in FIG. As shown in FIG. 18, even when the absorbent main body 10 is bent according to the steps shown in FIGS. Can be obtained. As shown in FIG. 18, the left and right flap portions 10 </ b> L and 10 </ b> R of the front side portion 10 a and the rear side portion 10 b form the top surface 1 of the absorbent main body 10. Further, the top surface portion 1 is formed with a through hole 7 that communicates with the internal space. Moreover, the left and right side portions 2 and 3 of the absorbent main body 10 form the width direction inner portions of the left and right flap portions 10L and 10R. Further, a mountain fold line 8 is formed along the depth direction at the center of the absorbent body 10 in the width direction. Furthermore, a leak-proof sheet 20 is attached to the lower end portion 5 of the side surface portions 2 and 3 of the absorbent main body 10 across the left and right side surface portions 2 and 3. As described above, the three-dimensional absorbent article 100 having the through hole 7 in the top surface portion 1 can also be obtained by the method shown in FIG.

[7. Fourth Embodiment]
Then, with reference to FIGS. 19-24, 4th Embodiment of the absorbent article 100 which concerns on this invention is described. In the fourth embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made focusing on a configuration different from the above-described embodiment.

  FIG. 19 is a perspective view showing an outline of an absorbent article 100 according to the fourth embodiment of the present invention. As FIG. 19 shows, the absorbent article 100 which concerns on this invention has comprised the cylindrical three-dimensional shape which has the space 4 inside. In the present embodiment, the back surfaces of both ends of one planar rectangular absorbent main body 10 are formed in a cylindrical shape having a space 4 extending along the depth direction (D) with the palms aligned. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and left and right side surface portions 2 extending from the left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (the left side surface portion 2 and the right side surface portion 3) and a space 4 formed between the left and right side surface portions 2 and 3. This space 4 has penetrated along the depth direction (D) from the wearer's ventral end to the dorsal end. Furthermore, a liquid-impermeable leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3 of the absorbent main body 10. The leak-proof sheet 20 is joined across the left and right side portions 2 and 3, and also has a function of connecting the side portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed in the top surface portion 1 of the absorbent main body 10.

  20 shows an exploded perspective view of the absorbent article 100, and FIG. 21 shows a cross-sectional view of the absorbent article. As shown in FIGS. 2 and 21, the absorbent article 100 includes an absorbent main body 10 and a leak-proof sheet 20 attached to a lower part thereof.

  From the unfolded state as shown in FIG. 20, the outer sheet 11, the inner sheet 12, and the absorbent body 13 are bonded together to form the absorbent main body 10, and both left and right ends in the width direction (W) of the absorbent main body 10. Is bent toward the inner sheet 12 side, and its lower end is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 provided with the absorptive main body 10 and the leak-proof sheet 20 becomes a cylindrical three-dimensional shape as shown in FIGS. Furthermore, as shown in FIG. 21, the leak-proof sheet 20 is attached across the left side surface portion 2 and the right side surface portion 3 at the lower end portion 5 of the absorbent main body 10. For this reason, it can be said that the leak-proof sheet 20 has a function of connecting the left side surface portion 2 and the right side surface portion 3 of the absorbent main body 10.

  FIG. 22 shows an example of a state where the absorbent article 100 is sandwiched between the crotch of the wearer. As shown in FIG. 22, in the absorbent main body 10, the top surface portion 1 that forms a flat surface is in close contact with the inseam of the wearer, and the side surface portions 2 and 3 located on the left and right sides thereof are on the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side surface portions 2 and 3, the absorbent main body 10 has a high cushioning property as a whole, and the state of close contact with the crotch and the inner thigh is maintained. Thereby, it becomes difficult to produce a clearance gap between the absorptive main body 10 and a wearer's skin, and even when it is a case where it mounts | wears with the wearer who is taking the attitude | position of a lateral position or a half lateral position, It is possible to effectively prevent urine leakage from the side surfaces 2 and 3 side. Furthermore, since the leak-proof sheet 20 is attached to the lower end portion 5 of the absorbent main body 10, it is possible to avoid contamination of underwear, sheets, or disposable diapers mounted in layers. Further, when the absorbent article 100 is replaced, the replacement work can be easily completed without making the hands dirty by pulling out the leak-proof sheet 20 with the handle.

  As shown in FIGS. 19 to 23, in the absorbent article 100 of the present invention, a plurality of squeezed lines 31, 32, and 33 are formed on the absorbent body 13. Each pressing line is formed by partially denting the absorber 13 in the thickness direction. In particular, each pressing line can be formed by partially pressing and compressing the absorbent body 13 from both sides or either one of the skin facing surface side and the skin non-facing surface side. For this reason, in the site | part in which the pressing line was formed, the density of the absorptive material 13a which comprises the absorber 13 will increase. Thus, the absorber 13 becomes easy to bend along the pressing line by forming the pressing line in the absorber 13. Moreover, since the density of the absorptive material 13a increases in the site | part in which the pressing line was formed, the absorber 13 improves the stress with respect to the external force added to the direction parallel to the extension direction of a pressing line. Moreover, since the absorber 13 is partially depressed in the site | part in which the pressing line was formed, a bodily fluid will flow along this pressing line, and a bodily fluid will spread | diffuse easily in the extension direction of a pressing line. In addition, a pressing line may be formed in the skin opposing surface side of the absorber 13, may be formed in the skin non-opposing surface side, and may be formed in these both sides. Below, the pattern of the pressing line formed in the absorber 13 is demonstrated in detail.

  FIG. 23 is a diagram for explaining a pattern of pressing lines formed in the absorbent body 13 and shows a developed state of the absorbent body 13. As shown in FIG. 23, the absorbent body 13 is formed with a first pressing line 31 extending along the width direction at a portion corresponding to the top surface portion 1 of the absorbent main body 10. A plurality of first pressing lines 31 are formed at predetermined intervals in the depth direction, and each of the first pressing lines 31 has a linear shape parallel to the width direction. Although the space | interval of the some 1st pressing wire 31 is not specifically limited, For example, it is preferable that the space | interval of 1st pressing wire 31 is 3 mm-30 mm or 5 mm-20 mm. Basically, the first pressing wire 31 extends over the entire width direction of the top surface portion 1. That is, the first pressing line 31 preferably reaches the boundary between the top surface portion 1 and the left side surface portion 2 and the boundary between the top surface portion 1 and the right side surface portion 3. Further, as described above, the through hole 7 is formed in the top surface portion 1. In this case, it is preferable that the first pressing line 31 reaches the periphery of the through hole 7.

  Thus, the stress of the top surface part 1 with respect to the external force added from the width direction can be raised by forming the some 1st pressing line 31 along the width direction in the top surface part 1. FIG. By improving the stress of the top surface portion 1, the top surface portion 1 and the space 4 positioned below the top surface portion 1 are less likely to be crushed. The shape can also be retained. Moreover, the body fluid which touched the top surface part 1 becomes easy to spread | diffuse in the width direction by forming the 1st pressing line 31 extended in the width direction in the top surface part 1 of the absorber 13. FIG. Thereby, since a bodily fluid can be rapidly absorbed in the wide range from the top | upper surface part 1 to the side parts 2 and 3, the urine leak prevention effect can be heightened.

  Further, as shown in FIG. 23, the absorbent body 13 extends in the depth direction at a position corresponding to the boundary between the top surface portion 1 of the absorbent main body 10 and the left and right side surface portions 2 and 3 (that is, the mountain crease 8). A second pressing line 32 is formed. For this reason, the absorptive main body 10 is bent along the second pressing line 32 formed in the absorbent body 13. That is, the mountain fold line 8 of the absorbent main body 10 has a shape corresponding to the second pressing line 32 of the absorbent body 13. As shown in FIG. 23, the second pressing line 32 extends over substantially the entire region of the absorbent body 13 in the depth direction. For example, when the length of the absorber 13 in the depth direction is 100%, the second pressing line 32 extends over a length range of 80 to 100% or 90 to 100% in the depth direction. Preferably it is.

  Each of the pair of left and right second pressing lines 32 is formed in an arc shape projecting outward in the width direction. That is, the distance between the pair of left and right second pressing lines 32 is the narrowest at the front end portion and the rear end portion in the depth direction and is the widest at the center portion in the depth direction. Thus, by making each of the left and right second pressing lines 32 arc-shaped, the top surface portion 1 that is a region between the second pressing lines 32 has a substantially elliptical shape in plan view. When the top surface portion 1 is defined by the arc-shaped second pressing line 32, the top surface portion 1 is shown in FIG. 19 when the absorbent main body 10 is folded along the second pressing line 32. In addition, the front end portion and the rear end portion in the depth direction rise. That is, as shown in FIG. 19, in the state where the absorbent main body 10 has a cylindrical three-dimensional shape, the front end both end portions in the depth direction of the top surface portion 1 are positioned above the center portion in the depth direction. To do. By making the 2nd pressing line 32 into circular arc shape, the state of such a top | upper surface part 1 can be hold | maintained naturally. The front end portion of the top surface portion 1 in the depth direction is thinner than the center portion and rises upward, and thus fits appropriately to the lower abdomen of the wearer. Moreover, since the rear-end part of the depth direction of the top | upper surface part 1 is also thin compared with the center part, and has stood up upwards, it fits a wearer's buttocks appropriately. Thereby, it can prevent more effectively that urine and feces leak.

  Moreover, as FIG.19 and FIG.23 shows, the 1st pressing line 31 is formed from the 2nd pressing line 32 of the left side to the 2nd pressing line 32 of the right side, or the center penetration. It is formed from the hole 7 to the left and right second pressing lines 32. Thus, the shape of the top surface part 1 which the 2nd pressing line 32 demarcates can be hold | maintained by forming the 1st pressing line 31 over the substantially whole area of the width direction of the top surface part 1. FIG. . That is, since the density of the absorptive material is high at the site where the first pressing line 31 is formed, the absorber 13 is strongly stressed against the external pressure from the width direction. Therefore, even if the top surface portion 1 defined by the second squeezing line 32 is sandwiched between both legs of the wearer, the top surface part 1 has a planar state that is not easily crushed by the action of the first squeezing line 31. Can be maintained.

  Further, as shown in FIG. 23, the absorbent body 13 is formed with a plurality of third pressing lines 33 extending in the depth direction on each of the left side surface portion 2 and the right side surface portion 3. The plurality of third squeezing lines 33 include an arcuate squeezing line 33a projecting in the same direction as the second squeezing line 32 in the unfolded state, and a linear squeezing line 33b extending in parallel with the depth direction. It is. The arc-shaped pressing line 33a can be said to be an arc shape protruding downward in a state where the absorbent main body 10 has a cylindrical three-dimensional shape (see FIG. 19). In this way, by forming the arc-shaped pressing lines 33a on the left and right side surface portions 2 and 3, the top surface portion 1 bends in the depth direction and deforms necessary to become three-dimensional. , 3, and since no gap is formed between the top surface portion 1 and the wearer's lower abdomen or buttocks, leakage can be prevented. Furthermore, in the region between the arc-shaped pressing line 33a and the second pressing line 32, the left and right side surface parts 2 and 3 can be easily maintained in a bulging state. Since the internal space 4 is widely secured, a large amount of urine and feces can be collected. Moreover, the stress with respect to the external pressure from a depth direction can be improved by forming the linear pressing line 33b in the left-right side parts 2 and 3. FIG. When the length of the absorber 13 in the depth direction is 100%, the arc-shaped pressing line 33a and the linear pressing line 33b included in the third pressing line 33 are the same as the second pressing line 32. It preferably extends over a length range of 80-100% or 90-100% in the depth direction.

  Fig.24 (a) to FIG.24 (e) has shown the example of the manufacturing process of the absorbent article 100 which concerns on 4th Embodiment. FIG. 24 shows a cross-sectional view along the line XXIV-XXIV together with each drawing. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 24 (a) to 24 (e). That is, first, the rectangular outer sheet 11 is prepared (FIG. 24A). In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this time. Next, the rectangular absorbent body 13 in which the through-holes 7 are formed is placed on the skin non-facing surface side of the outer sheet 11, and the inner sheet 12 is placed on the skin non-facing surface side of the absorbent body 13. (FIG. 24B). At this stage, a plurality of pressing lines 31, 32, 33 are formed in the absorbent body 13 in the pattern described above. Further, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. In addition, you may join the absorber 13 to both the outer surface sheet 11 and the inner surface sheet 12, or any one. Thereby, the absorptive main body 10 is obtained. In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this stage. Next, the absorbent main body 10 is folded in two along the through-hole 7 formed in the absorbent body 13 toward the inner surface sheet 12 side (FIG. 24C). That is, the sheet is folded in half so that the outer sheet 11 is on the outer side and the inner sheet 12 is on the inner side. At this time, the through hole 7 of the absorber 13 is positioned at the top of the fold. Thereafter, the apex portion where the through-hole 7 of the absorber 13 is located is cut off, and the through-hole 7 having substantially the same shape as the absorber 13 is also formed in the outer sheet 11 and the inner sheet 12 (FIG. 24D). At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are also substantially simultaneously cut off at the same position as the through hole 7 of the absorber 13. The through hole 7 can be formed. Then, the leak-proof sheet 20 is joined to the position corresponding to the lower end part of the absorptive main body 10 (FIG. 24 (e)). In addition, you may add the process of forming the mountain crease 8 in the position in which the arc-shaped 2nd pressing line 32 is formed in the absorber 13. FIG. Moreover, you may add the process of adhere | attaching the edge part (namely, edge part by which the leak-proof sheet | seat 20 is arrange | positioned) on the opposite side to the half-folded vertex with a hot-melt-adhesive etc.

  By following said manufacturing process, the absorbent article 100 in which the through-hole 7 was formed can be manufactured efficiently. Further, as shown in FIG. 24 (c), after the through hole 7 is formed in the absorbent body 13, the entire absorbent main body 10 is folded in two along the through hole 7. The folds attached to the top surface portion 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 is a flat surface and no crease remains. However, the crease formed on the top surface portion 1 is minimized by forming the crease that is unavoidably generated during the manufacturing process along the through hole 7. Can be limited. Thereby, it is also possible to make a state in which almost no creases remain on the top surface portion 1 at the time of wearing.

[8. Fifth Embodiment]
Then, with reference to FIG.25 and FIG.26, 5th Embodiment of the absorbent article 100 which concerns on this invention is described. In the fifth embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made centering on a configuration different from the above-described embodiment.

  FIG. 25 is an exploded perspective view of the absorbent article 100 according to the fifth embodiment, and FIG. 26 is a cross-sectional view of the absorbent article 100 according to the fifth embodiment. As shown in FIGS. 25 and 26, in the absorbent article 100 according to the fifth embodiment, the absorbent body 13 has a structure in which a main absorbent body 13 and a secondary absorbent body 14 are laminated.

  As shown in FIG. 26, in the present embodiment, the main absorbent body 13 is located on the top surface portion 1 and the left and right side surface portions 2 and 3 of the absorbent main body 10. That is, the main absorbent body 13 in the fifth embodiment has substantially the same configuration as the absorbent body 13 in the fourth embodiment described above. On the other hand, the secondary absorber 14 is disposed only on the top surface portion 1 of the absorbent main body 10. In particular, the secondary absorbent body 14 is disposed on the skin non-facing surface side of the main absorbent body 13, that is, between the main absorbent body 13 and the inner surface sheet 12. In addition, what is necessary is just to comprise the secondary absorber 14 from an absorptive material and a core wrap sheet | seat similarly to the main absorber 13. FIG. As in the present embodiment, by superposing the main absorber 13 and the sub-absorber 14 on the top surface portion 1, the amount of body fluid absorbed by the top surface portion 1 is increased. For this reason, it can be said that this embodiment is a form for women with a large amount of body fluid in direct contact with the top surface portion 1. In the present embodiment, the through holes 7 are formed in both the main absorber 13 and the sub absorber 14, and both the through holes 7 are connected to the space 4. In addition, although illustration is abbreviate | omitted, the sub absorber 14 can also be arrange | positioned between the skin opposing surface side of the main absorber 13, ie, the main absorber 13, and the outer surface sheet 11.

  Moreover, as FIG.25 and FIG.26 shows, the 1st pressing line 31 extended along the width direction is formed in the secondary absorber 14 located in the top | upper surface part 1 in this embodiment. A plurality of first pressing lines 31 are formed at predetermined intervals in the depth direction, and each of the first pressing lines 31 has a linear shape parallel to the width direction. About the effect | action of the 1st pressing line 31 formed in the top | upper surface part 1, it is as above-mentioned. That is, by forming the plurality of first pressing lines 31 on the auxiliary absorbent body 14 located on the top surface portion 1, the stress with respect to the external force from the width direction is increased, and the body pressure is rapidly and rapidly increased by the first pressing lines 31. Can diffuse.

  In the present embodiment, the main absorbent body 13 is formed with a plurality of third pressing lines 33 extending in the depth direction on each of the left side surface portion 2 and the right side surface portion 3. The 3rd pressing line 33 formed in the main absorber 13 is formed in the linear form extended in parallel with a depth direction. By forming the straight third squeezing lines 33 on the left and right side surface portions 2 and 3, the stress against the external pressure from the depth direction can be improved.

  As above-mentioned, in this embodiment, the 1st pressing line 31 extended in the width direction is formed in the subabsorber 14, and the 3rd pressing line 33 extended in the depth direction is formed in the main absorber 13. As shown in FIG. However, for example, it is also possible to form both the first pressing line 31 extending in the width direction and the third pressing line 33 extending in the going direction in the main absorbent body 13.

[9. Sixth Embodiment]
Then, with reference to FIG.27 and FIG.28, 6th Embodiment of the absorbent article 100 which concerns on this invention is described. FIG. 27 shows an exploded perspective view of the absorbent article 100 according to the sixth embodiment, and FIG. 28 shows a development view and a side view of the absorbent article 100 according to the sixth embodiment. The sixth embodiment corresponds to a modification of the above-described fourth embodiment, and the basic components are the same. However, the sixth embodiment differs from the fourth embodiment in that the outer shape of the absorbent article 100 in a developed state is circular.

  As shown in FIG. 27, in the sixth embodiment, the outer sheet 11, the inner sheet 12, and the absorber 13 are formed into a circle (or an ellipse) in plan view. For this reason, as shown in the plan view of FIG. 28A, the absorbent main body 10 in which the absorbent body 13 is laminated between the outer sheet 11 and the inner sheet 12 also has a circular outer shape in a plan view in the unfolded state. (Or oval). Moreover, as shown in the side view of FIG. 28 (b), a leak-proof sheet 20 straddles the left and right side portions 2, 3 at the lower end portions 5 of the left and right side portions 2, 3 of the absorbent main body 10. It is attached. In this manner, by forming the absorbent main body 10 in a circular shape, it is possible to eliminate the corners below the front end portion and below the rear end portion in the depth direction as compared with the case where the absorbent main body 10 is molded into a rectangle. For this reason, the size of the absorbent article 100 as a whole can be made compact by molding the absorbent main body 10 into a circular shape. Further, in the embodiment in which the absorbent main body 10 is molded into a rectangle, corners remain in the depth direction below the front end portion and below the rear end portion, and these corners are caught by underwear or the like so that the absorbent article 100 is in the crotch. It may be difficult to pinch. On the other hand, by forming the absorbent main body 10 in a circular shape as in the present embodiment, the edges below the front end portion and the rear end portion in the depth direction are arcuate, so that they are not easily caught by clothes when worn. It can be removed smoothly. In addition, what is necessary is just to change suitably according to the use of the absorbent article 100 whether the external shape of the absorptive main body 10 is made into a rectangle (4th Embodiment) or a circle (6th Embodiment).

[10. Seventh Embodiment]
Then, with reference to FIGS. 29-33, 7th Embodiment of the absorbent article 100 which concerns on this invention is described. In the seventh embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made centering on a configuration different from that of the above-described embodiment.

  FIG. 29 is a perspective view showing an outline of the absorbent article 100 according to the present invention. As FIG. 29 shows, the absorbent article 100 which concerns on this invention has comprised the cylindrical three-dimensional shape which has the space 4 inside. In the present embodiment, the back surfaces of both ends of one planar rectangular absorbent main body 10 are formed in a cylindrical shape having a space 4 extending along the depth direction (D) with the palms aligned. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and left and right side surface portions 2 extending from the left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (the left side surface portion 2 and the right side surface portion 3) and a space 4 formed between the left and right side surface portions 2 and 3. This space 4 has penetrated along the depth direction (D) from the wearer's ventral end to the dorsal end. Furthermore, a liquid-impermeable leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3 of the absorbent main body 10. The leak-proof sheet 20 is joined across the left and right side portions 2 and 3, and also has a function of connecting the side portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed in the top surface portion 1 of the absorbent main body 10.

  30 shows an exploded perspective view of the absorbent article 100, and FIG. 31 shows a cross-sectional view of the absorbent article. As shown in FIGS. 29 to 31, the absorbent article 100 includes an absorbent main body 10 and a leak-proof sheet 20 attached to the lower part thereof.

  As shown in FIG. 30, the absorbent body 13 has at least a lattice-shaped pressing wire 41 formed on the top surface portion 1. The pressing wire 41 is a linear recess formed by partially compressing the absorbent body 13. In addition, the lattice shape means a state in which a group of pressing lines extending in a certain direction intersects with a group of pressing lines extending in a different direction. The pressing line 41 may be formed in a rhombic lattice pattern as shown in FIG. 30 or the like, or may be formed in a square lattice pattern. That is, the grid-like pressing lines 41 extend at least along the width direction (W) of the absorbent article, or along a direction inclined in a range of 1 to 45 degrees with respect to the width direction (W). Includes an extension. For example, the angle (θ) at which the squeezing line 41 is inclined with respect to the width direction of the absorbent article can be in the range of 0 to 45 degrees, particularly 30 to 45 degrees, or 35 to 45 degrees. It is preferable.

  Moreover, the pressing line 41 can be basically formed by compressing the absorber 13 from the skin facing surface side. However, the pressing line 41 may be formed by compressing the absorbent body 13 from the skin non-facing surface side, or compressing the absorbent body 13 from both sides of the skin facing surface and the skin non-facing surface. It may be formed by. Thus, since the pressing wire 41 is formed by compressing the absorber 13, the strength of the absorber 13 is improved at the portion (the top surface portion 1) where the pressing wire 41 is formed. In particular, as described above, the lattice-shaped absorber 13 extends along the width direction (W) of the absorbent article or extends along a direction inclined within a predetermined range with respect to the width direction (W). Is included. For this reason, the absorber 13 can be said that the stress with respect to the external force from the width direction improves in the site | part of the top | upper surface part 1 in which the pressing line 41 was formed.

  As shown in FIG. 29 and FIG. 30, the stress on the top surface portion 1 is increased by forming the lattice-shaped pressing lines 41 on the absorbent body 13 in the portion corresponding to the top surface portion 1 of the absorbent article 100. For this reason, the shape of the top surface portion 1 can be maintained and the space 4 between the left and right side surfaces 2 and 3 can be maintained even when the absorbent biological product 100 is sandwiched between the legs of the wearer. can do. This makes it easier for the absorbent article 100 to come into close contact with the wearer's inseam and inner thigh. Moreover, by forming the grid-like pressing lines 41 on the top surface portion 1 of the absorbent body 13, body fluids that have touched the top surface portion 1 are likely to diffuse along the pressing lines 41. Thereby, since a bodily fluid can be rapidly absorbed in the wide range from the top | upper surface part 1 to the side parts 2 and 3, the urine leak prevention effect can be heightened.

  In the example shown in FIGS. 29 and 30, the pressing wire 41 is formed only in the top surface portion 1 of the absorber 13. However, in this invention, the pressing line 41 should just be formed in the top | upper surface part 1 at least, may be formed in the left-right side parts 2 and 3, and may be formed in the absorber 13 whole. Good.

  From the developed state as shown in FIG. 30, the outer sheet 11, the inner sheet 12, and the absorber 13 are bonded together to form the absorbent main body 10, and both left and right ends in the width direction (W) of the absorbent main body 10. Is bent toward the inner sheet 12 side, and its lower end is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 provided with the absorptive main body 10 and the leak-proof sheet 20 becomes a cylindrical three-dimensional shape as shown in FIG. Furthermore, as shown in FIG. 31, the leak-proof sheet 20 is attached across the left side surface portion 2 and the right side surface portion 3 at the lower end portion 5 of the absorbent main body 10. For this reason, it can be said that the leak-proof sheet 20 has a function of connecting the left side surface portion 2 and the right side surface portion 3 of the absorbent main body 10.

  Further, as shown in FIGS. 29 and 30, the through hole 7 is preferably formed in a region of the top surface portion 1 where the grid-like pressing lines 41 are formed. That is, it is preferable that the periphery of the through hole 7 is surrounded by the pressing line 41, and the pressing line 41 reaches the periphery of the through hole 7. That is, as shown in the partially enlarged view of FIG. 30, when the pressing wire 41 reaches the edge of the through hole 7, a recess is also formed at the edge of the through hole 7. Moreover, as above-mentioned, since the intensity | strength improves the absorber 13 in the area | region in which the pressing wire 41 is formed, by providing the through-hole 7 in the area | region of this grid-like pressing wire 41, the through-hole 7 is provided. The shape can be maintained. In the present invention, as described above, the lattice-shaped pressing wires 41 are provided on the top surface portion 1 to increase the rigidity in the width direction of the top surface portion 1 to prevent the deformation of the shape. For this reason, even when the through-hole 7 is provided in the top | upper surface part 1, the through-hole 7 cannot be obstruct | occluded easily by the effect | action of the pressing wire 41, and the function as a hole can be exhibited.

  As described above, the through-hole 7 is formed in all of the outer sheet 11, the inner sheet 12, and the absorber 13 that constitute the top surface portion 1. For this reason, as shown in FIG. 31, the outer sheet 11 and the inner sheet 12 are moved along the outline of the through hole 7 in the through hole 7 so that the contents of the absorber 13 do not protrude from the edge of the through hole 7. It is preferable to join. Thereby, exposure of the absorber 13 can be prevented.

  FIG. 32 shows an example of a state in which the absorbent article 100 is sandwiched between the crotch of the wearer. As shown in FIG. 32, in the absorbent main body 10, the top surface portion 1 that forms a flat surface is in close contact with the inseam of the wearer, and the side surface portions 2 and 3 that are located on the left and right sides of the top surface portion 1 In close contact. Further, since the space 4 is held between the left and right side surface portions 2 and 3, the absorbent main body 10 has a high cushioning property as a whole, and the state of close contact with the crotch and the inner thigh is maintained. Thereby, it becomes difficult to produce a clearance gap between the absorptive main body 10 and a wearer's skin, and even when it is a case where it mounts | wears with the wearer who is taking the attitude | position of a lateral position or a half lateral position, It is possible to effectively prevent urine leakage from the side surfaces 2 and 3 side. Furthermore, since the leak-proof sheet 20 is attached to the lower end portion 5 of the absorbent main body 10, it is possible to avoid contamination of underwear, sheets, or disposable diapers mounted in layers. Further, when the absorbent article 100 is replaced, the replacement work can be easily completed without making the hands dirty by pulling out the leak-proof sheet 20 with the handle.

  Fig.33 (a) to FIG.33 (e) has shown the example of the manufacturing process of the absorbent article 100 which concerns on 7th Embodiment. FIG. 33 shows a cross-sectional view along the line XXXIII-XXXIII together with each drawing. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 33 (a) to 33 (e). That is, first, a rectangular outer sheet 11 is prepared, and the rectangular absorbent body 13 in which the through holes 7 and the grid-like pressing lines 41 are formed is placed on the skin non-facing surface side of the outer sheet 11 (FIG. 33 (a)). In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this time. Next, the inner surface sheet 12 is placed on the skin 13 non-facing surface side of the absorbent body 13 (FIG. 33B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. In addition, you may join the absorber 13 to both the outer surface sheet 11 and the inner surface sheet 12, or any one. Thereby, the absorptive main body 10 is obtained. In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this stage. Next, the absorbent main body 10 is folded in two along the through hole 7 formed in the absorbent body 13 toward the inner surface sheet 12 side (FIG. 33C). That is, the sheet is folded in half so that the outer sheet 11 is on the outer side and the inner sheet 12 is on the inner side. At this time, the through hole 7 of the absorber 13 is positioned at the top of the fold. Thereafter, the apex portion where the through-hole 7 of the absorber 13 is located is cut off, and the through-hole 7 having substantially the same shape as the absorber 13 is formed in the outer sheet 11 and the inner sheet 12 (FIG. 33 (d)). At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are also substantially simultaneously cut off at the same position as the through hole 7 of the absorber 13. The through hole 7 can be formed. Then, the leak-proof sheet 20 is joined to the position corresponding to the lower end part of the absorptive main body 10 (FIG. 33 (e)). In addition, you may add the process of forming the mountain crease 8 in the appropriate position of the absorptive main body 10 which comprises the absorbent article 100. FIG. Moreover, you may add the process of adhere | attaching the edge part (namely, edge part by which the leak-proof sheet | seat 20 is arrange | positioned) on the opposite side to the half-folded vertex with a hot-melt-adhesive etc.

  By following said manufacturing process, the absorbent article 100 in which the through-hole 7 was formed can be manufactured efficiently. Further, as shown in FIG. 33 (c), after the through-hole 7 is formed in the absorbent body 13, the entire absorbent main body 10 is folded in two along the through-hole 7. The folds attached to the top surface portion 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 is a flat surface and no crease remains. However, the crease formed on the top surface portion 1 is minimized by forming the crease that is unavoidably generated during the manufacturing process along the through hole 7. Can be limited. Thereby, it is also possible to make a state in which almost no creases remain on the top surface portion 1 at the time of wearing.

[11. Eighth Embodiment]
Subsequently, an eighth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. 34 to 36. In the eighth embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made centering on a configuration different from that of the above-described embodiment.

  FIG. 34 is an exploded perspective view of the absorbent article 100 according to the eighth embodiment, and FIG. 35 is a cross-sectional view of the absorbent article 100 according to the second embodiment. As shown in FIGS. 34 and 35, the absorbent article 100 according to the eighth embodiment further includes a sub-absorber 14 in addition to the components described in the seventh embodiment.

  As shown in FIG. 35, in the present embodiment, the secondary absorbent body 14 is disposed on the top surface portion 1 of the absorbent main body 10. In particular, the secondary absorbent body 14 is disposed on the skin non-facing surface side of the absorbent body 13 (hereinafter also referred to as “main absorbent body”), that is, between the main absorbent body 13 and the inner surface sheet 12. In addition, what is necessary is just to comprise the subabsorber 14 from the absorptive material 14a and the core wrap sheet | seat 14b similarly to the main absorber 13. FIG. As in the present embodiment, by superposing the main absorber 13 and the sub-absorber 14 on the top surface portion 1, the amount of body fluid absorbed by the top surface portion 1 is increased. For this reason, it can be said that this embodiment is a form for women with a large amount of body fluid in direct contact with the top surface portion 1. Note that, when the auxiliary absorber 14 is disposed on the top surface portion 1, the through-hole 7 is also formed in the auxiliary absorber 14. By providing the top surface portion 1 with the main absorbent body 13 and the secondary absorbent body 14 to form a two-layer structure, the rigidity is further increased in the width direction, and the through hole 7 can be prevented from being blocked. Moreover, although illustration is abbreviate | omitted, the sub absorber 14 can also be arrange | positioned between the skin opposing surface side of the main absorber 13, ie, between the absorber 13 and the outer surface sheet 11. FIG. In the present embodiment, the sub-absorber 14 may be disposed at least on the top surface portion 1, and may be disposed on the left and right side surface portions 2 and 3. However, as in the embodiment shown in FIG. 35, the secondary absorber 14 is preferably disposed only on the top surface portion 1.

  36 (a) and 36 (b) show the main absorber 13 and the sub-absorber 14 separately, and FIGS. 36 (c) and 36 (d) show the sectional shapes in XXXVI-XXXVI. . FIG. 37 shows a pattern of pressing lines 41 formed on the main absorbent body 13 and a pattern of pressing lines 51 formed on the secondary absorbent body 14 in a state where the main absorbent body 13 and the secondary absorbent body 14 are overlapped. Is an enlarged view. 36 and 37, only the main absorber 13 and the sub-absorber 14 are extracted conceptually.

  As shown in FIGS. 36 and 37, in the eighth embodiment, pressing lines 41 and 51 in which the absorbent bodies 13 and 14 are recessed in the thickness direction in the main absorbent body 13 and the secondary absorbent body 14, respectively. A plurality of are formed. That is, a plurality of pressing lines 41 and 51 are formed in each of the main absorbent body 13 and the sub absorbent body 14. The pressing lines 41 and 51 are formed by partially pressing and compressing the pressing lines 41 and 51 from both sides or either one of the skin facing surface side and the skin non-facing surface side. For this reason, in the site | part in which the pressing lines 41 and 51 were formed, the density of the absorptive materials 13a and 14a in each absorber 13 and 14 will increase. And the pressing line 31 formed in the main absorber 13 and the pressing line 51 formed in the sub-absorber 14 form a pattern that at least partially intersects each other when viewed from the plane direction. Below, the pattern of the pressing line 41 formed in the main absorber 13 and the pattern of the pressing line 51 formed in the sub absorber 14 are demonstrated in detail.

  As shown in FIG. 36, pressing lines 41 are formed in the main absorbent body 13 in a rhombic lattice pattern. Here, the “rhombic lattice pattern” is a pattern in which a plurality of squeezing lines extending in a direction inclined with respect to the longitudinal direction and the width direction intersect to define a rhombic (diamond) non-squeezed region. Say. For example, as shown in FIG. 36, the angle (θ) at which the squeezing line is inclined with respect to the width direction of the absorbent article can be in the range of 1 to 45 degrees, and further 30 to 45 degrees, or It is preferably 35 to 45 degrees. In particular, in this embodiment, the pattern of the pressing line 41 in the main absorbent body 13 is a regular pattern in which all the non-squeezing regions 42 surrounded by the pressing line 41 are orthorhombic (rhombic). A square lattice pattern). As described above, the main absorbent body 13 is conceptually formed with a plurality of squeezed lines 41, a non-squeezed region 42 surrounded by the squeezed lines 41, and an intersection 43 where the squeezed lines 41 intersect. can do. Hereinafter, for convenience, the pressing line 41 in the main absorbent body 13 is referred to as an “upper pressing line 41”, the non-squeezing region 42 is referred to as an “upper non-squeezing region 42”, and the intersection portion 43 is referred to as an “upper intersection portion 43”.

  On the other hand, the squeezing lines 51 are formed in the secondary absorbent body 14 in a square lattice pattern. Here, the “square grid pattern” means that a plurality of squeezing lines extending in parallel with the longitudinal direction intersect with a plurality of squeezing lines extending in parallel with the width direction to define a square non-squeezed region. A pattern. In particular, in this embodiment, the pattern of the pressing line 51 in the sub-absorbent body 14 is a regular pattern (a square lattice pattern) in which all of the non-squeezing regions 52 surrounded by the pressing line 51 are square. It has become. Thus, also in the sub-absorbent body 14, a plurality of pressing lines 51, a non-squeezing region 52 surrounded by the pressing lines 51, and an intersection point 53 where the pressing lines 51 intersect are formed. can do. Hereinafter, for convenience, the pressing line 51 in the auxiliary absorbent body 14 is referred to as a “lower pressing line 51”, the non-squeezing region 52 is referred to as a “lower non-squeezing region 52”, and the intersection portion 53 is referred to as a “lower intersection portion 53”. .

  Moreover, in this embodiment, the upper side compression line 41 is formed by compressing the main absorber 13 from the skin opposing surface side and making it dent. Similarly, the lower squeezing line 51 is formed by compressing the sub absorbent body 14 from the skin facing surface side and making it dent. For this reason, in the state in which the main absorbent body 13 and the secondary absorbent body 14 are overlapped, a gap is formed between the parts where the lower pressing line 51 is formed in the secondary absorbent body 14.

  As shown in FIG. 37, in the present embodiment, the upper intersection portion 43 of the main absorbent body 13 and the lower intersection portion 53 of the secondary absorbent body 14 overlap each other in a state where the absorbent bodies 13 and 14 are overlapped. . Further, among the plurality of upper intersecting points 43 in the main absorbent body 13, there are those that overlap with the center (intersection of diagonal lines) of the lower non-compressed region 52 of the sub absorbent body 14. In particular, in the range where the pattern of the upper pressing line 41 of the main absorbent body 13 and the pattern of the lower pressing line 51 of the secondary absorbent body 14 overlap, the upper intersection part 43 is within the range of all the lower non-pressed areas 52. Will exist. For this reason, in this embodiment, it turns out that the upper pressing line 41 has overlapped in the position corresponded to the diagonal of the lower non-pressing area | region 52 which makes square shape. Furthermore, in this embodiment, it turns out that the lower pressing line 51 has overlapped in the range of the upper non-pressing area | region 42. FIG.

  In addition, as shown in FIG. 36, the length D1 of the diagonal line along the longitudinal direction of the upper non-compressed region 42 (rectangular square) is the length L in the longitudinal direction of the lower non-compressed region 52 (square). Nearly equal (D1 = L). Moreover, the length D2 of the diagonal along the width direction of the upper non-compressed region 42 (rectangular square) is substantially equal to the length B of the lower non-compressed region 52 (square) in the width direction (D2 = B). Note that “substantially” in this specification means that an error of ± 5% is allowed. By satisfy | filling these conditions, the upper pressing line 41 will overlap in the position corresponded to the diagonal of the lower non-pressing area | region 52 which makes square shape.

  Thus, in this embodiment, the lower pressing line 51 overlaps within the range of the upper non-squeezing region 42, the upper pressing line 41 and the upper intersection part 43 overlap within the range of the lower non-squeezing region 52, and The upper intersection portion 43 and the lower intersection portion 53 overlap each other. Therefore, the body fluid diffused along the upper pressing line 41 of the main absorbent body 13 falls on the sub absorbent body 14 and is absorbed by the lower non-pressed area 52. Further, the body fluid staying at the upper intersection portion 43 of the main absorbent body 13 falls on the sub absorbent body 14 and diffuses along the lower compressed line 51 through the lower intersection portion 53. Furthermore, the body fluid diffused along the lower pressing line 51 of the sub absorbent body 14 is absorbed by the upper non-squeezing region 42 of the main absorbent body 13. The lower pressing line 51 can also diffuse body fluid in the diagonal direction of the lattice pattern of the upper pressing line 41. Thereby, by forming such a pattern, it becomes possible to guide body fluid to the non-squeezed regions 42 and 52, which have conventionally been considered to have a slow absorption time.

  Here, the specific numerical value regarding the component of an absorbent article is demonstrated. For example, the thickness of each absorbent body 13, 14, that is, the thickness of the non-pressed regions 42, 52 is preferably 5 mm to 20 mm, and particularly preferably 8 mm to 15 mm. Moreover, it is preferable that the thickness of each absorber 13 and 14 in the site | part in which the pressing lines 41 and 51 were formed is 1 mm-10 mm, and it is especially preferable that they are 2 mm-5 mm. However, as a matter of course, the thickness of the part where the pressing lines 41 and 51 are formed is smaller than the thickness of the non-squeezing regions 42 and 52. For example, the thickness of the site | part in which the pressing lines 41 and 51 were formed is 3 to 50% with respect to the thickness of the non-pressing area | regions 42 and 52, and it is preferable that it is especially 5 to 20%.

  Moreover, it is preferable that the width | variety of each pressing wire 41 and 51 is 1 mm-5 mm, and it is preferable that it is especially 2 mm-4 mm. Moreover, it is preferable that the length D1 of the diagonal line in the longitudinal direction of the upper non-pressing area | region 42 shown in FIG. A preferable numerical range of the length D2 of the diagonal line in the width direction of the upper non-compressed region 42 is the same as the length D1 described above. The length D1 and the length D2 are preferably substantially equal, but may be different. That is, the shape of the upper non-squeezed region 42 is not limited to a regular rhombic shape (regular rhombus), and may be other rhombic shapes. Moreover, it is preferable that the length L of the lower non-pressing area | region 52 shown in FIG. 36 is 10 mm-50 mm, and it is especially preferable that it is 20 mm-40 mm, or 30 mm. A preferable numerical range of the width B of the lower non-compressed region 52 is the same as the length L described above. The length L and the width B are preferably substantially equal, but may be different. That is, the shape of the lower non-squeezed region 52 is not limited to a square, but may be another square. As described above, the preferred embodiment is such that the length D1 and the length L are substantially equal, and the length D2 and the width B are substantially equal. However, the present invention is not limited to this.

  Moreover, the pressing lines 41 and 51 formed in the absorbent bodies 13 and 14 have a wide range in the longitudinal direction so that the body fluid discharged near the crotch can be diffused widely to the front body and the back body. It is preferable to be formed. Specifically, the length in the longitudinal direction of the region in which the pressing lines 41 and 51 are formed is preferably 60% or more with respect to the length in the longitudinal direction of the absorbent bodies 13 and 14, and 60% to 100%, 70% to 100%, or 80% to 100% is particularly preferable. Moreover, the pressing lines 41 and 51 formed in the absorbent bodies 13 and 14 have a wide range in the width direction so that the body fluid discharged near the center in the width direction can be widely diffused outward in the width direction. It is preferable to be formed. Specifically, the maximum width in the width direction of the region where the upper pressing line 41 is formed is preferably 60% or more with respect to the width in the width direction of the top surface portion 1 of the main absorbent body 13, and 60% to 100%, 70% to 100%, or 80% to 100% is particularly preferable. Moreover, it is preferable that the maximum width of the width direction of the area | region where the lower side compression line 51 was formed is 60% or more with respect to the width of the width direction of the subabsorbent body 14, 60% -100%, 70%- 100% or 80% to 100% is particularly preferable.

  Moreover, in the figure, the example in which the pressing lines 41 and 51 were formed by denting both the absorptive materials 13a and 14a and the core wrap sheets 13b and 14b which comprise each absorber 13 and 14 is shown. However, the pressing lines 41 and 51 should just be formed by compressing at least the absorptive material 13a and 14a. That is, after compressing the absorptive materials 13a and 14a and forming the pressing lines 41 and 51, the core wrap sheets 13b and 14b may be joined so as to cover the absorptive materials 34 and 44. In this sense, it is sufficient that the squeezing lines 41 and 51 are formed on the absorbent materials 13a and 14a constituting the respective absorbent bodies 13 and 14.

[12. Ninth Embodiment]
Then, with reference to FIG.38 and FIG.39, the absorbent article which concerns on the 9th Embodiment of this invention is demonstrated. In the ninth embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made centering on a configuration different from that of the above-described embodiment.

  38A and 38B show the main absorber 13 and the sub-absorber 14 separately, and FIGS. 38C and 38D show the cross-sectional shapes in XXXVIII-XXXVIII. . In addition, FIG. 39 shows a pattern of pressing lines 41 formed on the main absorbent body 13 and a pattern of pressing lines 51 formed on the secondary absorbent body 14 in a state where the main absorbent body 13 and the secondary absorbent body 14 are overlapped. Is an enlarged view. 38 and 39 conceptually show only the main absorbent body 13 and the secondary absorbent body 14 extracted.

  The ninth embodiment is different from the eighth embodiment in the pattern of the pressing lines 41 and 51 formed in the absorbent bodies 13 and 14. As shown in FIGS. 38 and 39, the main absorbent body 13 is formed with an upper compressed line 41 in a square lattice pattern, and the secondary absorbent body 14 is formed with a lower compressed line 51 having an orthorhombic shape. It is formed in a lattice pattern. Here, the orthorhombic grid pattern and the square grid pattern are basically the same as those described in the eighth embodiment. However, in the ninth embodiment, in a state where the main absorber 13 and the sub absorber 14 are overlapped, a square lattice pattern formed on the main absorber 13 and an orthorhombic square formed on the sub absorber 14 are used. The relative positional relationship of the grid pattern is different from that of the eighth embodiment.

  As can be seen from the drawings, in the ninth embodiment, the area of the upper non-squeezed region 42 is larger than the area of the lower non-squeezed region 52. For this reason, when the main absorbent body 13 and the secondary absorbent body 14 are overlapped, the lower non-compressed region 52 (rhombic square) is accommodated in the range of the upper non-compressed region 42 (square).

  Further, in the ninth embodiment, four lower pressing lines 52 that define a certain lower non-squeezing area 52 (rectangular square) are respectively formed on the four upper pressing lines 41 that define a certain upper non-squeezing area 42 (square). The side intersection parts 53 overlap. For this reason, as FIG. 39 shows, it turns out that the lower non-compressed area | region 52 (rectangular square) fits in the range of the upper non-compressed area | region 42 (square). That is, the center of the upper non-squeezed area 42 (square) (intersection of diagonal lines) and the center of the lower non-squeezed area 52 (rectangular rectangle) (intersection of diagonal lines) coincide. Further, as shown in FIG. 38, the length L in the longitudinal direction of the upper non-squeezed region 42 (square) is the length D1 of the diagonal line along the longitudinal direction of the lower non-squeezed region 52 (rectangular rectangle). Almost equal (L = D1). The length B in the width direction of the upper non-squeezed region 42 (square) is substantially equal to the length D2 of the diagonal line along the width direction of the lower non-squeezed region 52 (B = D2). By satisfying these conditions, four lower intersections defining a certain lower non-squeezed region 52 (rhombic square) on each of the four upper compressed lines 41 defining the upper non-squeezed region 42 (square). The part 53 will overlap.

  Further, as shown in FIG. 39, the upper intersection portions 43 respectively overlap the center (diagonal intersection) of the lower non-squeezed region 52 (the orthorhombic rectangle). From another point of view, there are a plurality of lower non-compressed regions 52 (rhombic squares) that overlap with the upper intersection portion 43 and those that do not overlap with the upper intersection portion 43. In the example shown in FIG. 39, among the plurality of rows of the lower non-squeezed region 52, every other row has a row in which the upper intersection portion 43 overlaps and a row in which the upper intersection portion 43 does not overlap. I understand that. Similarly, it turns out that the row | line | column of the upper side intersection part 43 and the row | line | column of the upper side intersection part 43 which do not overlap are alternately located in every other line among several rows of the lower non-pressing area | region 52.

  As described above, by forming the pattern of the upper pressing line 41 (square lattice shape) and the pattern of the lower pressing line 51 (regular rhombic lattice shape), the pressing lines are not formed densely in one absorber. However, the body fluid can be effectively diffused into the non-compressed region, and the body fluid can be absorbed in a wide range of the entire two-layer absorber. That is, the body fluid diffused along the upper pressing line 41 of the main absorbent body 13 is absorbed by the lower non-pressed area 52 of the sub absorbent body 14. For this reason, the bodily fluid which spread | diffused along the upper side compression line 41 of the main absorber 13 becomes difficult to reach an edge part, and the situation which leaks outside can be prevented effectively. Moreover, since it becomes possible to absorb body fluid in a wide range of the two-layer absorbers 13 and 14, the amount of body fluid absorbed is improved, and it is difficult for the wearer to feel uncomfortable even when worn for a long time. . In the intersection parts 43 and 53 formed in each absorber 13 and 14, since the pressing lines 41 and 51 cross, the bodily fluid tends to stay. Therefore, the body fluid staying at the upper intersection part 43 is effectively infiltrated into the lower non-compression area 52 by overlapping the upper intersection part 43 of the main absorbent body 13 on the lower non-compression area 52 of the auxiliary absorbent body 14. Is possible.

  In addition, as in the ninth embodiment, the body fluid that has penetrated into the main absorbent 13 can be obtained by setting the columns and rows of the lower non-squeezed region 52 where the upper intersection portions 43 overlap each other and every other row. It can be diffused to farther areas. For this reason, the body fluid that has permeated the main absorbent 13 can be diffused and permeated in a wide range of the secondary absorbent 14.

  Moreover, a pressing line has the function to flow a liquid as a groove | channel, and the function to diffuse a liquid along a pressing part using a capillary phenomenon to the non-squeezing area | region around a pressing part. Even when used in a form that does not function as a groove, the liquid is transferred from the squeezing line of one absorbent body to the squeezing line or non-squeezed region of the other absorbent body. The reason is as follows. That is, the squeezing line is obtained by crushing the absorbent material constituting the absorber with pressure. For this reason, if an absorber absorbs a liquid in the site | part in which the pressing line was formed, thickness will change. That is, when the pulp or SAP in the pressing line absorbs liquid, the interval between the pulps is relaxed over time, and the SAP swells. The thickness is almost the same. Thus, even if the pressing line has a depth before absorption, the depth gradually decreases as the liquid absorption proceeds. For this reason, it becomes easy to deliver a liquid from the pressing line of one absorber to the pressing line or non-pressing area | region provided in the other absorber which overlaps it. That is, since the squeezing line is a groove in the initial state, the liquid flows in preference to the squeezing line. And since the pressing line swells as the liquid absorption proceeds in the part where the pressing line is formed, as described above, the liquid is supplied to the pressing line or the non-squeezing region provided on the other absorbent body overlapping the swollen pressing line. Moving.

  Thus, it can be said that the pattern of the ninth embodiment has a wider body fluid diffusion range than the pattern of the eighth embodiment. On the other hand, it can be said that the pattern of the eighth embodiment has a higher body fluid absorption rate than the pattern of the ninth embodiment. For this reason, when forming a pressing line in each of the two-layer absorber, which of the pattern of the eighth embodiment and the pattern of the ninth embodiment is adopted depends on the performance required for the absorbent article. What is necessary is just to determine suitably in consideration.

  The width of each pressing line 41, 51, the length D1 of the diagonal line in the longitudinal direction of the upper non-squeezing area 42, the length D2 of the diagonal line in the width direction, or the length L in the longitudinal direction of the lower non-squeezing area 52 About the value of the width | variety B, it is preferable to set it as the range similar to 8th Embodiment mentioned above.

[13. Tenth Embodiment]
Subsequently, a tenth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. 40 to 44. In the tenth embodiment, description of the same configuration as that of the above-described embodiment will be omitted, and description will be made focusing on a configuration different from the above-described embodiment.

  FIG. 40 is a perspective view showing an outline of the absorbent article 100 according to the present invention. As FIG. 40 shows, the absorbent article 100 which concerns on this invention has comprised the cylindrical three-dimensional shape which has the space 4 inside. In the present embodiment, the back surfaces of both ends of one planar rectangular absorbent main body 10 are formed in a cylindrical shape having a space 4 extending along the depth direction (D) with the palms aligned. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface that comes into contact with the wearer's crotch, and left and right side surface portions 2 extending from the left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (the left side surface portion 2 and the right side surface portion 3) and a space 4 formed between the left and right side surface portions 2 and 3. This space 4 has penetrated along the depth direction (D) from the wearer's ventral end to the dorsal end. Furthermore, a liquid-impermeable leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side surface portions 2 and 3 of the absorbent main body 10. The leak-proof sheet 20 is joined across the left and right side portions 2 and 3, and also has a function of connecting the side portions 2 and 3. Further, a through hole 7 connected to the internal space 4 is formed in the top surface portion 1 of the absorbent main body 10.

  41 shows an exploded perspective view of the absorbent article 100, and FIG. 42 shows a cross-sectional view of the absorbent article. As shown in FIGS. 40 to 42, the absorbent article 100 includes an absorbent main body 10 and a leak-proof sheet 20 attached to the lower part thereof.

  As shown in FIGS. 40 and 41, the absorbent body 13 has a plurality of pressing lines 41 formed on at least the left and right side surface portions 2 and 3. The pressing wire 41 is a linear recess formed by partially compressing the absorbent body 13. The plurality of squeezing lines are preferably a plurality of parallel squeezing lines or a plurality of squeezing lines that define a closed region. Moreover, it is especially preferable that the plurality of pressing lines are a plurality of parallel pressing lines that define a closed region. In the embodiment shown in FIGS. 40 and 41 and the like, the pressing lines are formed in a lattice shape. In addition, the lattice shape means a state in which a group of pressing lines extending in a certain direction intersects with a group of pressing lines extending in a different direction. The pressing line 41 may be formed in a rhombic lattice pattern as shown in FIG. 41 or the like, or may be formed in a square lattice pattern. That is, the grid-like pressing lines 41 extend along the width direction (W) of the absorbent article or extend in the width direction (W ) That extend along the direction inclined by 1 to 45 degrees with respect to. For example, the angle (θ) at which the squeezing line 41 is inclined with respect to the width direction of the absorbent article can be in the range of 0 to 45 degrees, particularly 30 to 45 degrees, or 35 to 45 degrees. It is preferable.

  Moreover, the pressing line 41 can be basically formed by compressing the absorber 13 from the skin facing surface side. However, the pressing line 41 may be formed by compressing the absorbent body 13 from the skin non-facing surface side, or compressing the absorbent body 13 from both sides of the skin facing surface and the skin non-facing surface. It may be formed by. Thus, since the pressing wire 41 is the site | part which compressed the absorber 13, the intensity | strength improves the absorber 13 in the site | part (left and right side surface parts 2 and 3) in which the pressing wire 41 was formed.

  As shown in FIGS. 40 and 41, by forming grid-like pressing lines 41 on the left and right side portions 2 and 3 of the absorbent body 13, the body fluid that has contacted or penetrated the left and right side portions 2 and 3 is It spreads along the pressing line 41. Thereby, since a bodily fluid can be rapidly absorbed over the wide range of the side parts 2 and 3, the urine leak prevention effect can be improved. Moreover, in the site | part corresponded to the right and left side surface parts 2 and 3 of the absorbent article 100, the stress of this right and left side surface parts 2 and 3 becomes strong by forming the grid-like pressing wire 41 in the absorber 13. FIG. For this reason, even if it is the state which pinched | absorbed the absorption biological article 100 between the wearer's both legs, the shape of the top | upper surface part 1 can be maintained and the space 4 between the right and left side surfaces 2 and 3 is maintained. Can do. This makes it easier for the absorbent article 100 to come into close contact with the wearer's inseam and inner thigh.

  In addition, in the example shown in FIG.40 and FIG.41, the pressing line 41 is formed only in the left and right side surface parts 2 and 3 of the absorber 13. FIG. However, in the present invention, the pressing wire 41 may be formed not only on the left and right side surface portions 2 and 3 but also on the top surface portion 1, or may be formed on the entire absorbent body 13.

  41, the outer sheet 11, the inner sheet 12, and the absorbent body 13 are bonded together to form the absorbent main body 10, and both left and right ends of the absorbent main body 10 in the width direction (W). Is bent toward the inner sheet 12 side, and its lower end is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 provided with the absorptive main body 10 and the leak-proof sheet 20 becomes a cylindrical three-dimensional shape as shown in FIG. Furthermore, as shown in FIG. 42, the leak-proof sheet 20 is attached across the left side surface portion 2 and the right side surface portion 3 at the lower end portion 5 of the absorbent main body 10. For this reason, it can be said that the leak-proof sheet 20 has a function of connecting the left side surface portion 2 and the right side surface portion 3 of the absorbent main body 10.

  Moreover, as FIG. 40 to FIG. 42 shows, the grid | lattice-like pressing line 41 is formed in the liquid absorption part 6 to which at least the leak-proof sheet 20 is not attached among the left and right side surface parts 2 and 3. It is preferable. By providing the grid-like pressing lines 41 in the liquid absorption part 6, it is possible to avoid the pressing lines 41 from being hidden behind the leak-proof sheet 20. Thereby, the bodily fluid adhering to or penetrating the liquid absorption part 6 diffuses into the range along the pressing line 41. Moreover, it is preferable that the pressing wire 41 is continuously formed not only from the liquid absorption part 6 but from the liquid absorption part 6 to the lower end part 5 to which the leak-proof sheet 20 is attached. That is, it is preferable that the grid-like pressing wire 41 extends continuously from the liquid absorption part 6 to the lower end part 5 beyond the edge of the leak-proof sheet 20. As described above, the pressing line 41 is provided so as to be connected from the liquid absorbing part 6 to the lower end part 5, whereby the body fluid absorbed by the liquid absorbing part 6 is passed through the pressing line 41 to the back of the leak-proof sheet 20. It is possible to quickly lead to the hidden lower end 5. Since the lower end portion 5 is hidden behind the leak-proof sheet 20, the body fluid hardly penetrates into the lower end portion 5, but the squeezed wire 41 functions as a flow path for carrying the body fluid to the lower end portion 5. Thereby, a bodily fluid can be diffused in a wider range.

  In addition, as shown in FIG. 40, in the present embodiment, the left and right side surface portions 2 and 3 are formed with the compressed wire forming region 6a, which is a region where the grid-shaped compressed wires 41 are formed, and the compressed wire 41. It is divided into an uncompressed line forming region 6b that is not a region. In this embodiment, the compression line formation area 6a is provided on the lower end side of the left and right side surface parts 2, 3, and the compression line non-formation area 6b is between the top surface part 1 (mountain crease 8) and the compression line formation area 6a. Is provided. Since the absorbent body 13 is partially compressed, the pressing line forming region 6a is somewhat hard to the touch. On the other hand, the pressing line non-formation area 6b does not have the pressing line 41 and is relatively soft to the touch. Then, the touch of the absorbent article 100 which contacts a wearer's hip joint vicinity can be improved by providing the pressing line 41 between the top | upper surface part 1 and the pressing line formation area | region 6a. Thereby, the wearing feeling of the absorbent article 100 is improved. Moreover, even if the area | region which forms the pressing line 41 is limited to the lower end side of the right-and-left side parts 2 and 3, since the bodily fluid which penetrate | infiltrated the absorber 41 flows below according to gravity, finally the pressing line formation area 6a To reach. And the bodily fluid which reached | attained the pressing line formation area | region 6a spread | diffuses widely along the pressing line 41. FIG. Thus, in this invention, the pressing line non-formation area | region 6b is provided above the right-and-left side parts 2 and 3, and the pressing line formation area 6a is provided below it. Thereby, the irritation | stimulation with respect to skin becomes less to a wearer compared with the case where a pressing line is formed in the whole right and left side surface parts 2 and 3, for example, maintaining the diffusibility of a bodily fluid, and can improve the touch. .

  Moreover, it is preferable that the length in the height direction (H) of the pressing line non-formation area | region 6b is 20% or more with respect to the whole length in the height direction (H) of the left and right side surfaces 2 and 3. . Specifically, the length in the height direction (H) of the compressed wire non-forming region 6b is preferably 20 to 70%, and more preferably 30 to 50%. Thus, the touch of the site | part which contacts a wearer's hip joint vicinity can be made soft by ensuring the range of the pressing line non-formation area | region 6b more than fixed.

  FIG. 43 shows an example of a state where the absorbent article 100 is sandwiched between the crotch of the wearer. As shown in FIG. 43, the top surface portion 1 forming a flat surface of the absorbent main body 10 is in close contact with the inseam of the wearer, and the side surface portions 2 and 3 located on the left and right sides thereof are on the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side surface portions 2 and 3, the absorbent main body 10 has a high cushioning property as a whole, and the state of close contact with the crotch and the inner thigh is maintained. Thereby, it becomes difficult to produce a clearance gap between the absorptive main body 10 and a wearer's skin, and even when it is a case where it mounts | wears with the wearer who is taking the attitude | position of a lateral position or a half lateral position, It is possible to effectively prevent urine leakage from the side surfaces 2 and 3 side. Furthermore, since the leak-proof sheet 20 is attached to the lower end portion 5 of the absorbent main body 10, it is possible to avoid contamination of underwear, sheets, or disposable diapers mounted in layers. Further, when the absorbent article 100 is replaced, the replacement work can be easily completed without making the hands dirty by pulling out the leak-proof sheet 20 with the handle.

  44 (a) to 44 (e) show an example of a manufacturing process of the absorbent article 100 according to the tenth embodiment. In FIG. 44, a cross-sectional view taken along line XLIV-XLIV is shown together with each drawing. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 44 (a) to 44 (e). That is, first, a rectangular outer sheet 11 is prepared, and the rectangular absorbent body 13 in which the through holes 7 and the grid-like pressing lines 41 are formed is placed on the skin non-facing surface side of the outer sheet 11 (FIG. 44 (a)). In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this time. Next, the inner surface sheet 12 is placed on the skin 13 non-facing surface side of the absorbent body 13 (FIG. 44B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. In addition, you may join the absorber 13 to both the outer surface sheet 11 and the inner surface sheet 12, or any one. Thereby, the absorptive main body 10 is obtained. In addition, the through-hole 7 is not formed in the outer surface sheet 11 at this stage. Next, the absorbent main body 10 is folded in two along the through-hole 7 formed in the absorbent body 13 toward the inner surface sheet 12 side (FIG. 44C). That is, the sheet is folded in half so that the outer sheet 11 is on the outer side and the inner sheet 12 is on the inner side. At this time, the through hole 7 of the absorber 13 is positioned at the top of the fold. Thereafter, the apex portion where the through-hole 7 of the absorber 13 is located is cut off, and the through-hole 7 having substantially the same shape as the absorber 13 is also formed in the outer sheet 11 and the inner sheet 12 (FIG. 44D). At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through hole 7 of the absorber 13, the outer sheet 11 and the inner sheet 12 are also substantially simultaneously cut off at the same position as the through hole 7 of the absorber 13. The through hole 7 can be formed. Then, the leak-proof sheet 20 is joined to the position corresponding to the lower end of the absorbent main body 10 (FIG. 44 (e)). At this time, the area | region (squeezing line formation area | region 6a) in which the pressing line 41 was formed is covered partially by the leak-proof sheet 20. FIG. In addition, you may add the process of forming the mountain crease 8 in the appropriate position of the absorptive main body 10 which comprises the absorbent article 100. FIG. Moreover, you may add the process of adhere | attaching the edge part (namely, edge part by which the leak-proof sheet | seat 20 is arrange | positioned) on the opposite side to the half-folded vertex with a hot-melt-adhesive etc.

  By following said manufacturing process, the absorbent article 100 in which the through-hole 7 was formed can be manufactured efficiently. Further, as shown in FIG. 44 (c), after the through hole 7 is formed in the absorbent body 13, the entire absorbent main body 10 is folded in two along the through hole 7. The folds attached to the top surface portion 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 is a flat surface and no crease remains. However, the crease formed on the top surface portion 1 is minimized by forming the crease that is unavoidably generated during the manufacturing process along the through hole 7. Can be limited. Thereby, it is also possible to make a state in which almost no creases remain on the top surface portion 1 at the time of wearing.

[14. Eleventh Embodiment]
Subsequently, an eleventh embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. 45 to 48. In the eleventh embodiment, description of the same configuration as that of the tenth embodiment described above will be omitted, and description will be made focusing on a configuration different from that of the tenth embodiment.

  45 shows an exploded perspective view of the absorbent article 100 according to the second embodiment, and FIG. 46 shows a cross-sectional view of the absorbent article 100 according to the second embodiment. As shown in FIGS. 45 and 46, the absorbent article 100 according to the second embodiment further includes two sub-absorbers 14 in addition to the components described in the tenth embodiment. .

  As shown in FIG. 46, in the present embodiment, the auxiliary absorbent bodies 14 are arranged one by one on the left and right side portions 2 and 3 of the absorbent main body 10. In particular, the two secondary absorbent bodies 14 are arranged on the skin non-facing surface side of the main absorbent body 13 constituting the top surface portion 1 and the left and right side surface portions 2, 3, that is, between the main absorbent body 13 and the inner sheet 12. Yes. In addition, what is necessary is just to comprise each sub absorber 14 from the absorptive material 14a and the core wrap sheet | seat 14b similarly to the main absorber 13. FIG. As in the present embodiment, by superposing the main absorbent body 13 and the secondary absorbent body 14 on the left and right side surface portions 2 and 3, the amount of body fluid absorbed at the side surface portions 2 and 3 is increased. In particular, a large amount of body fluid introduced into the space 4 through the through-hole 7 of the top surface portion 1 can be absorbed by the sub-absorber 14 disposed on each of the side surface portions 2 and 3. For this reason, it can be said that this embodiment is a form for men to use by inserting a penis into the through hole 7 of the top surface portion 1. As shown in FIG. 46, it is preferable that the sub-absorber 14 is disposed so as to overlap the main absorber 13 at least on the lower end portion 5 side of the left and right side surface portions 2 and 3. However, the sub absorbent body 14 may be disposed so as to overlap the main absorbent body 13 over the entire left and right side surface portions 2 and 3. Moreover, although illustration is abbreviate | omitted, the sub absorber 14 can also be arrange | positioned between the skin opposing surface side of the main absorber 13, ie, between the main absorber 13 and the outer surface sheet 11. FIG.

  As shown in FIGS. 45 and 46, in the eleventh embodiment, the compressed lines 41 and 51 in which the absorbent bodies 13 and 14 are recessed in the thickness direction in the main absorbent body 13 and the secondary absorbent body 14, respectively. A plurality of are formed. That is, a plurality of pressing lines 41 and 51 are formed in each of the main absorbent body 13 and the sub absorbent body 14. The pressing lines 41 and 51 are formed by partially pressing and compressing the pressing lines 41 and 51 from both sides or either one of the skin facing surface side and the skin non-facing surface side. For this reason, in the site | part in which the pressing lines 41 and 51 were formed, the density of the absorptive materials 13a and 14a in each absorber 13 and 14 will increase. And the pressing line 41 formed in the main absorber 13 and the pressing line 51 formed in the sub-absorber 14 form a pattern that at least partially intersects each other when viewed from the plane direction. Below, the pattern of the pressing line 41 formed in the main absorber 13 and the pattern of the pressing line 51 formed in the sub absorber 14 are demonstrated in detail.

  FIG. 47 shows a state in which the patterns of pressing lines 41 and 51 formed on the main absorbent body 13 and the secondary absorbent body 14 are overlapped. As shown in FIG. 45 and FIG. 47, the main absorbent body 13 has pressing lines 41 formed in a rhombic lattice pattern. Here, the “rhombic lattice pattern” is a pattern in which a plurality of squeezing lines extending in a direction inclined with respect to the longitudinal direction and the width direction intersect to define a rhombic (diamond) non-squeezed region. Say. For example, as shown in FIG. 47, the angle (θ) at which the squeezing line is inclined with respect to the width direction of the absorbent article can be in the range of 1 to 45 degrees, and further 30 to 45 degrees, or It is preferably 35 to 45 degrees. In particular, in this embodiment, the pattern of the pressing line 41 in the main absorbent body 13 is a regular pattern in which all the non-squeezing regions 42 surrounded by the pressing line 41 are orthorhombic (rhombic). A square lattice pattern). As described above, the main absorbent body 13 is conceptually formed with a plurality of squeezed lines 41, a non-squeezed region 42 surrounded by the squeezed lines 41, and an intersection 43 where the squeezed lines 41 intersect. can do. Hereinafter, for convenience, the pressing line 41 in the main absorbent body 13 is referred to as an “upper pressing line 41”, the non-squeezing region 42 is referred to as an “upper non-squeezing region 42”, and the intersection portion 43 is referred to as an “upper intersection portion 43”.

  On the other hand, the squeezing lines 51 are formed in the secondary absorbent body 14 in a square lattice pattern. Here, the “square grid pattern” means that a plurality of squeezing lines extending in parallel with the longitudinal direction intersect with a plurality of squeezing lines extending in parallel with the width direction to define a square non-squeezed region. A pattern. In particular, in this embodiment, the pattern of the pressing line 51 in the sub-absorbent body 14 is a regular pattern (a square lattice pattern) in which all of the non-squeezing regions 52 surrounded by the pressing line 51 are square. It has become. Thus, also in the sub-absorbent body 14, a plurality of pressing lines 51, a non-squeezing region 52 surrounded by the pressing lines 51, and an intersection point 53 where the pressing lines 51 intersect are formed. can do. Hereinafter, for convenience, the pressing line 51 in the auxiliary absorbent body 14 is referred to as a “lower pressing line 51”, the non-squeezing region 52 is referred to as a “lower non-squeezing region 52”, and the intersection portion 53 is referred to as a “lower intersection portion 53”. .

  Moreover, in this embodiment, the upper side compression line 41 is formed by compressing the main absorber 13 from the skin opposing surface side and making it dent. Similarly, the lower squeezing line 51 is formed by compressing the sub absorbent body 14 from the skin facing surface side and making it dent. For this reason, in the state in which the main absorbent body 13 and the secondary absorbent body 14 are overlapped, a gap is formed between the parts where the lower pressing line 51 is formed in the secondary absorbent body 14.

  As can be seen from FIG. 47, in this embodiment, the area of the lower non-squeezed region 52 is larger than the area of the upper non-squeezed region 42. For this reason, when the main absorbent body 13 and the secondary absorbent body 14 are overlapped, the upper non-compressed region 42 (the orthorhombic rectangular shape) is accommodated in the range of the lower non-compressed region 52 (square).

  Further, in the present embodiment, four upper intersections that define a certain upper non-squeezed region 42 (an orthorhombic square) on each of the lower compressed lines 51 that define a certain lower non-squeezed region 52 (square). The part 43 has overlapped. For this reason, as FIG. 47 shows, it turns out that the upper non-squeezing area | region 42 (rectangular square) is settled in the range of the lower non-squeezing area | region 52 (square). That is, the center of the lower non-squeezed area 52 (square) (intersection of diagonal lines) and the center of the upper non-squeezed area 42 (rectangular rectangle) (intersection of diagonal lines) coincide. Furthermore, as shown in FIG. 47, the length L in the longitudinal direction of the lower non-squeezed region 52 (square) is the length D1 of the diagonal line along the longitudinal direction of the upper non-squeezed region 42 (rhombus). Almost equal (L = D1). Moreover, the length B in the width direction of the lower non-squeezed region 52 (square) is substantially equal to the length D2 of the diagonal along the width direction of the upper non-squeezed region 42 (B = D2). By satisfying these conditions, four upper intersections that define a certain upper non-squeezed region 42 (rhombic rectangle) on each of the lower compressed lines 51 that define the lower non-squeezed region 52 (square). The part 43 will overlap. Note that “substantially” in this specification means that an error of ± 5% is allowed.

  As described above, by forming the pattern of the upper squeeze line 41 (rhombic rectangular lattice) and the pattern of the lower squeeze line 51 (square lattice), the compression line is not formed densely in one absorber. However, the body fluid can be effectively diffused into the non-compressed region, and the body fluid can be absorbed in a wide range of the entire two-layer absorber. That is, the body fluid diffused along the upper pressing line 41 of the main absorbent body 13 is absorbed by the lower non-pressed area 52 of the sub absorbent body 14. For this reason, the bodily fluid which spread | diffused along the upper side compression line 41 of the main absorber 13 becomes difficult to reach an edge part, and the situation which leaks outside can be prevented effectively. Moreover, since it becomes possible to absorb body fluid in a wide range of the two-layer absorbers 13 and 14, the amount of body fluid absorbed is improved, and it is difficult for the wearer to feel uncomfortable even when worn for a long time. . In the intersection parts 43 and 53 formed in each absorber 13 and 14, since the pressing lines 41 and 51 cross, the bodily fluid tends to stay. Therefore, by superposing the upper intersection part 43 of the main absorbent body 13 on the lower pressing line 51 of the sub absorbent body 14, the body fluid staying at the upper intersection part 43 is introduced into the lower pressing line 51, and the sub absorbent body 14. It is possible to effectively penetrate into

  FIG. 48 shows a modification of the pattern of the compressed line 41 formed on the main absorbent body 13 and the pattern of the compressed line 51 formed on the auxiliary absorbent body 14. In the modification shown in FIG. 48, the upper intersection portion 43 of the main absorbent body 13 and the lower intersection portion 53 of the secondary absorbent body 14 overlap each other in a state where the absorbent bodies 13 and 14 are overlapped. Further, among the plurality of upper intersecting points 43 in the main absorbent body 13, there are those that overlap with the center (intersection of diagonal lines) of the lower non-compressed region 52 of the sub absorbent body 14. In particular, in the range where the pattern of the upper pressing line 41 of the main absorbent body 13 and the pattern of the lower pressing line 51 of the secondary absorbent body 14 overlap, the upper intersection part 43 is within the range of all the lower non-pressed areas 52. Will exist. Moreover, in this embodiment, it turns out that the lower pressing line 51 has overlapped in the range of the upper non-pressing area | region 42. FIG.

  Thus, in the modification shown in FIG. 48, the lower pressing line 51 overlaps within the range of the upper non-squeezing region 42, and the upper pressing line 41 and the upper intersection part 43 are within the range of the lower non-squeezing region 52. The upper intersection 43 and the lower intersection 53 overlap. Therefore, the body fluid diffused along the upper pressing line 41 of the main absorbent body 13 falls on the sub absorbent body 14 and is absorbed by the lower non-pressed area 52. Further, the body fluid staying at the upper intersection portion 43 of the main absorbent body 13 falls on the sub absorbent body 14 and diffuses along the lower compressed line 51 through the lower intersection portion 53. Furthermore, the body fluid diffused along the lower pressing line 51 of the sub absorbent body 14 is absorbed by the upper non-squeezing region 42 of the main absorbent body 13. The lower pressing line 51 can also diffuse body fluid in the diagonal direction of the lattice pattern of the upper pressing line 41. Thereby, by forming such a pattern, it becomes possible to guide body fluid to the non-squeezed regions 42 and 52, which have conventionally been considered to have a slow absorption time.

  Thus, it can be said that the pattern shown in FIG. 48 has a faster body fluid absorption rate than the pattern of FIG. On the other hand, it can be said that the pattern of FIG. 47 has a wider diffusion range of the body fluid than the pattern of FIG. For this reason, when forming a squeezing line in each of the two-layer absorbent body, which pattern of FIG. 47 and FIG. 48 should be used may be appropriately determined in consideration of the performance required for the absorbent article. .
