Description

  TECHNICAL FIELD The present invention relates to an absorbent article to be applied to a wearer's inseam. More specifically, the present invention relates to an absorbent article suitable for being used by being sandwiched between inseams of a wearer in a lateral or semi-lateral position.

  2. Description of the Related Art Conventionally, there has been known an absorbent article of a type that is used by being superposed on an inner surface of a disposable diaper or underwear for adults. 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 covering the abdomen of the wearer, a back body covering the back of the wearer, and a crotch positioned therebetween and in contact with the crotch of the wearer. In general, it is performed (for example, Patent Document 1).

  Also, at the site of nursing care, when the caregiver applies the urine absorbing pad to the inseam of the wearer (cared person), the urine absorbing pad is folded in the length direction, and the cross section of the urine absorbing pad becomes W-shaped. In some cases, it is sandwiched between the inseam of the wearer (see FIG. 49). By folding in a W shape, the central convex portion of W comes into contact with the genitals, so that urine is easily absorbed. When the wearer is a male, the urine absorbing pad is U-shaped, and the penis is brought into contact with the bottom of the U so as to guide the direction of urine excretion.

  By the way, some wearers have symptoms such as paralysis and joint contracture, cannot sleep in a supine position, and can only take a lateral or semi-lateral position. As shown in FIG. 50, in a bedridden state in a lateral position or a semi-lateral position, the urine collection pad sandwiches between the wearer's legs because both legs remain tightly closed. There is a need. However, when the urine absorbing pad is folded in a W-shape or U-shape and sandwiched in a state where the thickness is generated, a gap is generated between the urine absorbing pad and the crotch of the wearer, and urine leakage easily occurs from the gap. (See FIG. 49).

  As shown in FIG. 49, the 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 absorbing pad 300 is folded in a W shape, the liquid impermeable back sheet 302 comes into contact with the inner thighs of both legs of the wearer. However, if the liquid-impermeable back sheet 302 is in contact with the inner thigh, urine flowing along the inner thigh cannot be absorbed by the urine absorbing pad, so that the back sheet 302 and the inner thigh There was a problem that urine easily leaked from between. Further, if the liquid impermeable back sheet 302 keeps in contact with the wearer's skin, it may cause skin trouble.

  Therefore, the present invention can fit a crotch of a wearer who takes a posture of a lateral position or a semi-lateral position without creating a gap, and appropriately absorbs body fluid flowing along the inner thigh to the outside. An object of the present invention is to provide an absorbent article that can prevent leakage.

  The inventor of the present invention has earnestly studied the means for solving the above problems, and as a result, the absorbent main body including the absorbent body is directed toward the top surface portion abutting the crotch of the wearer and the non-skin facing surface side thereof. It has a three-dimensional shape having left and right side portions extending so as to extend and a space formed between both side portions. Thereby, the present inventor has found that the absorbent body having the three-dimensional shape fits the crotch of a wearer who takes a posture of a lateral position or a semi-lateral position, and appropriately absorbs urine flowing along the inner thigh. To prevent leakage to the outside. The inventor has conceived that it is possible to solve the problems of the prior art based on the above findings, and has 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 body 10. The absorbent main body 10 has a plurality of sheet members and an absorber disposed between the plurality of sheet members. The absorbent main body 10 includes a top surface 1 having a surface in contact with a wearer's crotch, and left and right side portions 2 and 3 extending from the top surface toward the non-skin-facing surface side of the top surface 1. Have. Further, in the absorbent main body 10, a space is formed between the left and right side parts 2, 3.

  As in the above configuration, since the top surface 1 of the absorbent main body 10 is in close contact with the crotch of the wearer, the excreted body fluid can be first absorbed by the top surface 1. In addition, since the left and right side portions 2 and 3 of the absorbent main body 10 are attached to the inner thigh from the base of the leg of the wearer in the lateral position or the semi-lateral position, and adhere to the inner thigh. The body fluid flowing can also 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 absorbing pad, there is no irregularity in contact with the wearer's skin, and there is little mechanical irritation given to the skin. I'm done.

  In the absorbent article according to the present invention, it is preferable that the liquid impermeable leak-proof sheet 20 is attached to a 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 faces 2 and 3, so that the bodily fluid penetrating the side faces 2 and 3 reaches the leak-proof sheet 20 and stays there. Therefore, it is possible to prevent the body fluid from seeping out. Thereby, the underwear and the disposable diaper on which the present absorbent article is stacked are not stained. Moreover, when exchanging an absorbent article, since the leak prevention sheet 20 can be grasped and pulled out, the absorbent article can be exchanged without soiling the hands.

  In the absorbent article according to the present invention, the leakproof sheet 20 is attached to the lower end 5 of the left and right side portions 2 and 3 opposite to the top surface portion 1 so as to straddle these left and right side portions 2 and 3. Preferably. In this case, the left and right side portions 2 and 3 may have the liquid absorbing portion 6 to which the leak-proof sheet 20 is not attached, between the lower end portion 5 to which the leak-proof sheet 20 is attached and the top surface portion 1. preferable.

  Since the leakage prevention sheet 20 is attached to the lower end portions 5 of the left and right side parts 2 and 3 as in the above configuration, the effect of preventing leakage of bodily fluids is enhanced, and the leakage prevention sheet 20 is gripped by the absorbent article 20. Will be easier to replace. In addition, by providing the liquid absorbing portions 6 on the left and right side portions 2 and 3, it is possible to more reliably absorb the bodily fluid flowing along the inner thigh.

  In the absorbent article according to the present invention, it is preferable that a through hole 7 connected to the space 4 is formed in the top surface portion 1. The “through hole” may be a simple cut or an opening having a circular or polygonal area. Further, the “through hole” may be one having both ends closed, a slit 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 may have reached the part.

  By providing the through-hole 7 in the top surface portion 1 as in the above configuration, the bodily 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 bodily fluid is excreted at once, it can be efficiently absorbed. When the wearer is a male, the penis is inserted into the through hole 7 to guide the urine excretion direction.

  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 8 is formed as a boundary line between the top surface portion 1 and the left and right side surface portions 2 and 3. Is preferred. The “mountain fold” is a fold that is convex when viewed from the outer surface side of the absorbent article.

  By forming the mountain fold 8 on the boundary between the top surface 1 and the left and right side surfaces 2 and 3 as in the above configuration, the surface of the top surface 1 that contacts the skin can be made almost flat. it can. Thereby, the fit between the top surface portion 1 and the crotch of the wearer is improved. Further, since the space 4 formed between the side portions 2 and 3 is less likely to be crushed, the fit between the side 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 fold 9 is further formed between the top surface portion 1 and the leak-proof sheet 20 on both or one of the left and right side portions 2 and 3. The “valley fold” is a fold opposite to the above-described mountain fold, and is a fold that is concave when viewed from the outer surface side of the absorbent article.

  By forming the valley fold 9 in addition to the above-described ridge fold 8 as in the above configuration, the absorbent article can be folded with the top surface portion 1 lying down. For this reason, it becomes easy to store an absorbent article in a package or the like. In addition, in a state where the absorbent article is housed in the package, the top surface portion 1 does not need to be creased, so that the top surface portion 1 can be kept flat. This allows the absorbent article to be used immediately after being taken out of the package. As described above, it is preferable that the top surface portion 1 has basically no folds and is a flat surface.

  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 extension portion 22 extending from the fixing portion 21. In this case, it is preferable that the extension portion 22 has a length that can cover the top surface portion 1.

  Since the leak-proof sheet 20 has the extension 22 as in the above configuration, for example, before use of the absorbent article, the top surface 1 may be covered with the extension 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, by covering this portion with the extension portion 22, the sanitary condition can be maintained.

  Another aspect of the present invention relates to a product in which a plurality of absorbent articles 100 according to the first aspect are housed inside a package 200. In the product according to the present invention, it is preferable that the plurality of absorbent articles 100 be accommodated in the package 200 in a state of being folded at the mountain fold 8 and the valley fold 9.

  As in the above-described configuration, the mountain fold 8 and the valley fold 9 are formed in each of the absorbent articles 100, and the plurality of absorbent articles 100 are folded along the folds 8 and 9 to form the plurality of absorbent articles 100 into the package 200. Can be stored compactly inside. Moreover, by folding in this manner, the top surface 1 of the absorbent article 100 can be maintained in a flat state. That is, the absorbent article 100 can be housed inside the package 200 without making a fold on the top surface 1.

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

  By forming the first compression line 31 extending in the width direction on the top surface portion 1 of the absorber 13 as in the above configuration, the stress of the top surface portion 1 against external force applied from the width direction can be increased. This makes it easier for the absorbent main body 10 to more closely adhere to the wearer's crotch and inner thigh, and can also maintain the space 4 between the left and right side portions 2 and 3. In addition, by forming the first compressed line 31 extending in the width direction on the top surface 1 of the absorber 13, the body fluid that has touched the top surface 1 is easily diffused in the width direction. As a result, the body fluid can be rapidly absorbed in a wide range from the top surface portion 1 to the side surface portions 2 and 3, and the effect of preventing urine leakage can be enhanced.

  In the present invention, it is preferable that the boundary between the top surface portion 1 and the left and right side surface portions 2 and 3 is formed by the second compression line 32 extending in the depth direction in the absorber 13. 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 a second position is formed on 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. Is formed. For this reason, the second compression line 32 functions as a mountain fold that separates the top surface portion 1 from the left and right side surface portions 2 and 3.

  By forming the second compressed line 32 at the boundary between the top surface 1 and the left and right side surfaces 2 and 3 as in the above configuration, the shape of the top surface 1 can be easily maintained. This allows the top surface portion 1 to be more closely adhered to the wearer's crotch, so that urine leakage can be effectively prevented.

  In the present invention, the second compression line 32 is preferably formed in an arc shape that protrudes outward in the width direction.

  As in the above configuration, by forming the two second compression lines 32 in an arc shape projecting outward in the width direction, both front and rear ends in the depth direction of the top surface portion 1 rise, and the lower abdomen of the wearer's crotch. And the shape along the buttocks makes it easier to fit without gaps. This makes it possible to more effectively prevent excreted urine and stool from leaking.

  In the present invention, it is preferable that the absorber 13 have one or a plurality of third compression lines 33 extending in the depth direction on the left and right side parts 2 and 3.

  By forming the third compression line 33 extending in the depth direction on the left and right side portions 2 and 3 of the absorber 13 as in the above configuration, it is possible to increase the stress to the external force applied to the absorber 13 in the depth direction. it can. Further, by forming the third compression line 33, the space 4 between the left and right side portions 2 and 3 can be held.

  In the present invention, the absorber 13 may be one in which the main absorber 13 and the sub-absorber 14 are laminated in the thickness direction at least on the top surface portion 1. In this case, the first compression line 31 may be formed on both or any one of the main absorber 13 and the sub absorber 14.

  As described above, by forming the absorber constituting the top surface portion 1 into a two-layer structure of the main absorber 13 and the sub-absorber 14, the amount of absorption in the top surface portion 1 can be increased. Furthermore, since the thickness of the absorber of the top surface 1 is increased and the rigidity is high, the top surface 1 is less likely to be crushed in the width direction or to be out of shape. The main absorber 13 may be located on the top surface 1 and the left and right side surfaces 2 and 3, and the sub absorber 14 may be located only on the top surface 1. This makes it easy to bend the left and right side portions 2 and 3 at the boundary with the top surface portion 1, and as a result, it is easy to maintain the three-dimensional shape of the absorbent article having the space 4 inside.

  In the present invention, it is preferable that a through hole 7 connected to the space 4 is formed in the top surface portion 1 on which the first compression line 31 is 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, rigidity is increased in the width direction of the top surface portion 1 to prevent shape collapse. . For this reason, even when the through-hole 7 is provided in the top surface part 1, the through-hole 7 is hard to be closed, and the function as a hole can be exhibited. Further, by providing the top surface portion 1 with the sub-absorber 14 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, it is preferable that the lower ends of the left and right side portions 2 and 3 of the absorbent main body 10 are connected. Furthermore, it is preferable that a lattice-shaped squeezing line 41 is formed on the absorber 13 located on the top surface 1 of the absorbent article. The term "lattice-like" as used herein means a state in which a group of a plurality of compressed lines extending in a certain direction intersects with a group of a plurality of compressed lines extending in a different direction. For example, the “lattice” includes an orthorhombic lattice and a square lattice. The compression line 41 is formed by pressing the absorber 13 from one or both of the skin-facing surface side and the non-skin-facing surface side. Is formed. Note that the lattice-shaped squeezing line 41 may be formed at least in the top surface 1 of the absorber 13, may be formed on the left and right side surfaces 2 and 3, or may be formed on the entire absorber 13. May be.

  By forming the lattice-shaped squeezing lines 41 on the top surface portion 1 of the absorber 13 as in the above configuration, it is possible to increase the stress of the top surface portion 1 against external force applied particularly in the width direction of the absorbent article. As a result, the top surface portion 1 of the absorbent main body 10 is less likely to be crushed, so that it 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 be held. . Further, by forming the lattice-shaped compression lines 41 on the top surface 1 of the absorber 13, the bodily fluid that has touched the top surface 1 is easily diffused along the compression lines 41. As a result, the body fluid can be rapidly absorbed in a wide range from the top surface portion 1 to the side surface portions 2 and 3, and the effect of preventing urine leakage can be enhanced.

  In the present invention, the lattice-shaped squeezing lines 41 include those that extend along the width direction of the absorbent article, or those that extend along a direction inclined in the range of 1 degree or more and 45 degrees or less with respect to the width direction. Preferably.

  As in the above-described configuration, since the lattice-shaped squeezing line 41 includes a line extending along the width direction or a line extending at an angle of 45 degrees or less, the stress of the top surface portion 1 against external force applied in the width direction. Can be increased more effectively.

  In the absorbent article of the present invention, the leak-proof sheet 20 is attached to the lower end 5 of the left and right side portions 2 and 3 opposite to the top surface portion 1 so as to straddle the left and right side portions 2 and 3. Is preferred. The lower ends of the left and right side portions 2 and 3 are connected by the leak-proof sheet 20. Further, it is preferable that the left and right side portions 2 and 3 have a liquid absorbing portion 6 to which the leak-proof sheet 20 is not attached, between the lower end portion 5 to which the leak-proof sheet 20 is attached and the top surface portion 1.

  With the liquid impermeable leak-proof sheet 20 attached to the side portions 2 and 3 as in the above configuration, the bodily fluid permeating the side portions 2 and 3 reaches the leak-proof sheet 20 and stays there. As described above, it can be prevented from seeping out. Thereby, the underwear and the disposable diaper on which the present absorbent article is stacked are not stained. Further, when exchanging the absorbent article, it is only necessary to grasp and pull out the leak-proof sheet 20, so that the absorbent article can be exchanged without soiling the hands. Further, by providing the liquid absorbing portion 6 without the leakage prevention sheet 20 on the left and right side portions 2 and 3, the body fluid flowing along the inner thigh can be more reliably absorbed.

  In the present invention, it is preferable that the absorbent main body 10 further includes, on the top surface portion 1, an auxiliary absorber 14 that overlaps the absorber 13 (main absorber) in the thickness direction. In this case, the absorber 13 and the sub-absorber 14 each have a plurality of compression lines 41 and 51, and each of the compression lines 41 and 51 may intersect at least partially when viewed from the plane. preferable.

  By arranging and stacking the two absorbers 13 and 14 in the thickness direction as in the above configuration, the amount of absorption at the top surface can be increased. In addition, by forming the compression lines 41 and 51 on each of the absorbers 13 and 14, the diffusibility of the bodily fluid can be enhanced. By arranging the absorbers 13 and 14 so as to intersect the compression lines 41 and 51 with each other, it is possible to effectively infiltrate the body fluid into a region where no compression line is formed (a non-compression region). It becomes possible. That is, the body fluid diffused along the squeezing line of one absorber becomes more likely to be absorbed by the non-squeezed region of the other absorber. For this reason, the body fluid diffused along the squeezing line of one of the absorbers is less likely to reach the end portion, and the situation of leaking to the outside can be effectively prevented. Further, since the body fluid can be absorbed in a wide range of the two-layer absorbers 13 and 14, the absorption amount of the body fluid is improved and the wearer is less likely to feel discomfort even when worn for a long time. .

  In the present invention, the absorber 13 and the sub-absorber 14 are each composed of a plurality of non-squeezed regions 42 and 52 surrounded by squeezed lines 41 and 51 and a plurality of intersections 43 where the squeezed lines 41 and 51 intersect. , 53 are preferable. Furthermore, it is preferable that at least a part of one intersection of the absorber 13 and the sub-absorber 14 overlaps the other non-squeezed region.

  As in the above configuration, since the squeezing lines 41 and 51 intersect at the intersections 43 and 53 formed on the absorbers 13 and 14, body fluids are more likely to stay. Therefore, by overlapping the intersection of one absorber with the non-squeezed region of the other absorber, it becomes possible to effectively penetrate the bodily fluid retained at the intersection with the non-squeezed region. Thereby, body fluids such as urine excreted on the top surface portion 1 can be quickly diffused by efficiently using both of the two layers of the absorbers 13 and 14.

  In the present invention, it is preferable that a through hole 7 connected to the space 4 is formed in the top surface portion 1. In particular, it is preferable that the through-hole 7 is formed in a region of the top surface portion 1 where the lattice-shaped squeezing lines 41 are formed.

  As described above, in the present invention, by providing the grid-shaped squeezing lines 41 on the top surface 1, it is possible to increase rigidity in the width direction of the top surface 1 and prevent shape collapse. Therefore, even when the through-hole 7 is provided in the top surface portion 1, the through-hole 7 is hardly closed, and the function as a hole can be exhibited. In addition, by providing the top absorber 1 with the main absorber 13 and the sub absorber 14 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, a plurality of squeezing lines 41 may be formed on the absorber 13 located on the left and right side portions 2 and 3.

  Preferably, the plurality of squeezing lines 41 are 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. Further, the pressing lines 41 may be formed in a lattice shape. The term "lattice-like" as used herein means a state in which a group of a plurality of compressed lines extending in a certain direction intersects with a group of a plurality of compressed lines extending in a different direction. For example, the “lattice” includes an orthorhombic lattice and a square lattice. The compression line 41 is formed by pressing the absorber 13 from one or both of the skin-facing surface side and the non-skin-facing surface side. Is formed. Note that the plurality of compression lines 41 may be formed at least in the left and right side surfaces 2 and 3 of the absorber 13, may be formed on the top surface 1, or may be formed on the entire absorber 13. You may.

  By forming a plurality of squeezing lines 41 on the side portions 2 and 3 of the absorber 13 as in the above configuration, the body fluid attached or permeated on the side portions can be diffused over a wide range. Thereby, since the body fluid can be absorbed by the entire absorbent body 13, the body fluid flowing along the inner thigh can be appropriately absorbed by the absorbent body 13, and the body fluid can be effectively prevented from leaking out. Further, by forming the plurality of squeezing lines 41 on the side portions 2 and 3 of the absorber 13, the stress of the side portions 2 and 3 against external force applied to the absorbent can be increased. As a result, the side portions 2 and 3 of the absorbent main body 10 are less likely to be crushed, so that it becomes easier to adhere to the inner thigh of the wearer.

  In the absorbent article of the present invention, the leak-proof sheet 20 is attached to the lower end 5 of the left and right side portions 2 and 3 opposite to the top surface portion 1 so as to straddle the left and right side portions 2 and 3. Is preferred. The lower ends of the left and right side portions 2 and 3 are connected by the leak-proof sheet 20. Further, it is preferable that the left and right side portions 2 and 3 have a liquid absorbing portion 6 to which the leak-proof sheet 20 is not attached, between the lower end portion 5 to which the leak-proof sheet 20 is attached and the top surface portion 1.

  With the liquid impermeable leak-proof sheet 20 attached to the side portions 2 and 3 as in the above configuration, the bodily fluid permeating the side portions 2 and 3 reaches the leak-proof sheet 20 and stays there. As described above, it can be prevented from seeping out. Thereby, the underwear and the disposable diaper on which the present absorbent article is stacked are not stained. Further, when exchanging the absorbent article, it is only necessary to grasp and pull out the leak-proof sheet 20, so that the absorbent article can be exchanged without soiling the hands. Further, by providing the liquid absorbing portion 6 without the leakage prevention sheet 20 on the left and right side portions 2 and 3, the body fluid flowing along the inner thigh can be more reliably absorbed.

  In the absorbent article of the present invention, it is preferable that the squeezing line 41 is formed on the absorber 13 located at the liquid absorbing portion 6.

  By providing the plurality of compression lines 41 in the liquid absorbing section 6 as in the above configuration, it is possible to avoid that the compression lines 41 are hidden behind the leak-proof sheet 20. As a result, the bodily fluid that has adhered to or penetrated the liquid absorbing portion 6 diffuses over a wide range along the compression line 41.

  In the absorbent article of the present invention, it is preferable that the compression line 41 is formed on the absorbent body 13 from the liquid absorbing portion 6 to the lower end portion 5 to which the leak-proof sheet 20 is attached.

  Since the compression line 41 is provided so as to be connected to the lower end portion 5 from the liquid absorbing portion 6 as in the above configuration, the body fluid absorbed by the liquid absorbing portion 6 passes through the compression line 41 to form the leak-proof sheet 20. It can be quickly guided to the lower end portion 5 hidden behind. Since the lower end portion 5 is hidden behind the leak-proof sheet 20, the bodily fluid hardly permeates into the lower end portion 5, but the squeezing line 41 functions as a flow path for carrying the bodily fluid to the lower end portion 5. Thereby, the body fluid can be diffused over a wider range.

  In the absorbent article of the present invention, the absorbent main body 10 may further include, on the left and right side portions 2 and 3, a sub-absorber 14 overlapping the absorber 13 in the thickness direction. In this case, it is preferable that the compression line 51 is also formed on the sub-absorber 14. Furthermore, it is preferable that the compression line 41 of the absorber 13 and the compression line 51 of the sub-absorber 14 intersect at least partially.

  As in the above configuration, in the left and right side portions 2 and 3, 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 portions 2 and 3, the left and right sides are further added. By stacking the sub-absorbers 14 on the side surfaces 2 and 3, the amount of liquid absorbed by the side surfaces 2 and 3 increases. Thereby, even if a large amount of bodily fluid is excreted, urine leakage can be prevented. In addition, by forming the compression lines 41 and 51 on both the main absorber 13 and the sub-absorber 14 and intersecting these compression lines 41 and 51, a region (a non-compression region) where no compression line is formed is formed. It is also possible to effectively penetrate bodily fluids. Therefore, the body fluid diffused along the squeezing line of one absorber becomes more likely to be absorbed by the non-squeezed 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 to a wearer who takes a posture of a lateral position or a semi-lateral position without creating a gap in the crotch, and appropriately absorbs a bodily fluid flowing along an inner thigh. Leakage to the outside.

[1. First Embodiment]
A first embodiment of an absorbent article 100 according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing an outline of an absorbent article 100 according to the present invention. As shown in FIG. 1, the absorbent article 100 according to the present invention has a tubular three-dimensional shape having a space 4 therein. In the present embodiment, the back surfaces of both ends of one planar rectangular absorbent main body 10 are formed into a cylindrical shape having a space 4 extending along the depth direction (D) with their palms facing each other. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface in contact with the wearer's crotch, and left and right side surface portions 2 extending from both left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (left side surface 2 and right side surface 3) and a space 4 formed between the left and right side surfaces 2 and 3. The space 4 penetrates along the depth direction (D) from the abdominal end of the wearer to the dorsal end. Furthermore, a liquid-impermeable leakproof sheet 20 is attached to the lower end 5 of the left and right side surfaces 2 and 3 of the absorbent main body 10. The leakage prevention sheet 20 is joined across the left and right side parts 2 and 3 and also has a function of connecting the side parts 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 component which constitutes absorbent article 100 is explained concretely. FIG. 2 is an exploded perspective view of the absorbent article 100, and FIG. 3 is a 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 a lower portion thereof.

  The absorbent main body 10 is an element for absorbing and holding bodily fluids excreted from the crotch of the wearer. The absorbent main body 10 has a configuration in which the absorber 13 is interposed between a plurality of sheet members. Specifically, the absorbent main body 10 includes an outer sheet 11 that forms the outer surface (skin-facing surface) of the absorbent article 100, and an inner sheet 12 that forms the inner surface (skin non-facing surface) of the absorbent article 100. An absorber 13 is provided between the two sheets 11 and 12. In the present embodiment, the outer sheet 11, the inner sheet 12, and the absorber 13 are formed 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 circular shape, an elliptical shape, or another polygonal shape. Further, the outer sheet 11 and the inner sheet 12 have a length and width slightly larger than the absorber 13, and surround the absorber 13 with a known adhesive, heat fusion, ultrasonic wave, or the like. They are joined by fusion. Therefore, the absorber 13 is sealed in the outer sheet 11 and the inner sheet 12 whose periphery is joined.

  The outer sheet 11 is a sheet-like member that is in direct contact with the wearer's skin and allows body fluids such as urine to pass through the absorber 13. Therefore, 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 nonwoven fabric, or a porous film. Further, as the outer sheet 11, for example, a nonwoven fabric obtained by hydrophilizing a thermoplastic resin fiber such as polypropylene, polyethylene, polyester, or nylon may be used. Examples of the nonwoven fabric include an air-through nonwoven fabric, a point-bonded nonwoven fabric, a spun-bonded nonwoven fabric, and a melt-blown nonwoven fabric.

  The inner sheet 12 is formed of a material that does not directly contact the wearer's skin, but is capable of transmitting the bodily fluid introduced into the space 4 through the through-hole 7 of the top panel 1 to the absorber 13. Is preferred. Therefore, the inner sheet 12 is preferably made of a liquid-permeable material having high flexibility, like the outer sheet 11. Examples of the liquid-permeable material are as described above. However, the inner sheet 12 does not necessarily need to be formed of a liquid-permeable material, and may be formed of a liquid-impermeable material. An example of the liquid impermeable material is a plastic film made of a polyethylene resin. In particular, when the inner 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 in order to secure air permeability. Is preferred.

  The absorber 13 is a member for absorbing bodily fluids such as urine and retaining the absorbed bodily fluids. The absorber 13 is arranged between the outer sheet 11 and the inner sheet 12. Further, as described later, the number of the absorbers 13 arranged on the outer sheet 11 and the inner sheet 12 is not limited to one, and may be two or more. Further, the absorbent body 13 is bonded to both or any one of the outer sheet 11 and the inner sheet 12 with a hot melt adhesive or the like so that the position is not shifted between the outer sheet 11 and the inner sheet 12. Is also good. The absorber 13 basically includes an absorbent material 13a and a core wrap sheet 13b that covers the absorbent material 13a. As the absorbent material 13a, for example, fluff pulp obtained by crushing a fiber material such as softwood or hardwood, superabsorbent polymer (SAP), or a hydrophilic sheet may be used. As the absorbent material 13a, one of fluff pulp, superabsorbent polymer, and hydrophilic sheet may be used alone, or two or more of them may be used in combination. Generally, the absorbent material 13a is constituted by sprinkling a super absorbent polymer in fluff pulp. The core wrap sheet 13b is a sheet member for holding the shape by covering the absorbent material 13a. A liquid-permeable sheet member is used as the core wrap sheet 13b. As an example of the core wrap sheet 13b, thin paper such as tissue paper or a known nonwoven fabric can be used.

  The leakage prevention sheet 20 is a sheet member for preventing the 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 pulling out the absorbent article 100 that has absorbed body fluid from the crotch of the wearer. For this reason, the leakage prevention sheet 20 is attached to at least a part of the outer surfaces of the left and right side surfaces 2 and 3 of the absorbent main body 10. Specifically, it is preferable that the leakage prevention sheet 20 is attached to the outer surface of the lower end 5 of the left and right side parts 2 and 3 of the absorbent main body 10. The leak prevention sheet 20 is made of a liquid impermeable material in order to prevent leakage of body fluid. An example of the liquid impermeable material is a plastic film made of a polyethylene resin as described above. In particular, it is preferable to use a microporous polyethylene film in which a plurality of fine pores of 0.1 to 4 μm are formed in order to secure air permeability while maintaining liquid impermeability.

  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, and the lower end thereof is bound by the leak-proof sheet 20. Thus, the absorbent article 100 including the absorbent main body 10 and the leak-proof sheet 20 has a tubular three-dimensional shape as shown in FIG. Further, as shown in FIG. 3, a leak-proof sheet 20 is provided at the lower end 5 of the absorbent main body 10 across the left side surface 2 and the right side surface 3. For this reason, it can be said that the leakage prevention sheet 20 has a function of connecting the left side part 2 and the right side part 3 of the absorbent main body 10.

  In the example shown in FIG. 3, the absorbent main body 10 has a top surface 1 having a surface in contact with the crotch of the wearer, and extends from both left and right sides of the top surface 1 toward the non-skin-facing surface. The left and right side portions 2 and 3 are integrally connected. A mountain fold 8 is formed on the boundary between the top surface 1 and the left and right side surfaces 2 and 3. Thereby, the cross section of the absorbent main body 10 becomes an approximately inverted triangle. Further, the top surface 1 is located between the left and right mountain folds 8, and the top surface 1 is a substantially flat surface. In this way, by making the top surface 1 a flat surface without making any folds, the top surface 1 can easily adhere to the wearer's crotch. As shown in FIG. 3, the length B of the top surface 1 in the width direction (W) is preferably, for example, 20 mm to 150 mm, and particularly preferably 30 mm to 100 mm.

  As shown in FIG. 3, the left and right side surfaces 2 and 3 respectively have a lower end 5 which is a region where the leak-proof sheet 20 is joined, and a top surface 1 (mountain fold 8) from the lower end 5. And the liquid absorbing section 6 which is a region up to the above. The leak-proof sheet 20 is not joined to the liquid absorbing section 6. Therefore, the left and right side surfaces 2 and 3 can absorb the body fluid from the outer surface side in the liquid absorbing portion 6. When the absorbent article 100 is sandwiched between the inseams of the wearer in the side position or the semi-side position and the top surface portion 1 is brought into contact with the wearer's inseam, the left and right side portions 2 and 3 are placed on both legs of the wearer. Abut on the inner thigh. For this reason, by forming the liquid absorbing portion 6 capable of absorbing body fluid from the outer surface side on the left and right side portions 2 and 3, it is possible to effectively absorb body fluid flowing along the inner thigh of the wearer. Becomes The length T of the liquid absorbing portion 6 in the height direction (H) is preferably, for example, 20 mm to 200 mm, and more preferably 50 mm to 150 mm. Note that the left and right side portions 2 and 3 may be bonded to each other at a lower end portion (an end portion on the side where the leakage prevention sheet 20 is disposed) with a hot melt adhesive or the like.

  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 a bodily fluid is introduced into the space 4 through the through hole 7. I have. For this reason, as shown in FIG. 2, the through holes 7 are formed in all of the outer sheet 11, the inner sheet 12, and the absorber 13 that constitute the top section 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. 2 and the like. Further, the through hole 7 may be a simple cut. Further, the through-hole 7 may be a slit having one end reaching the front end or the rear end of the absorbent main body 10, or a crack having one end reaching the front end and the rear end of the absorbent main body 10. It may be. By forming the through holes 7 in this manner, 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. Therefore, even if a large amount of bodily fluid is excreted at once, urine leakage can be effectively prevented. Furthermore, when the wearer is a male, by inserting the penis into the through hole 7, the direction of urine excretion can be guided or fixed.

  FIG. 4 shows an example of a state where the absorbent article 100 is sandwiched between the legs of a wearer. As shown in FIG. 4, of the absorbent main body 10, the top surface portion 1, which is a flat surface, is in close contact with the wearer's crotch, and the side surface portions 2, 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 portions 2, 3, the absorbent main body 10 has a high cushioning property as a whole, and the close contact with the crotch and the inner thigh is maintained. Thereby, a gap is less likely to be formed between the absorbent main body 10 and the wearer's skin, and even when worn on a wearer in a lateral or semi-lateral position, the top surface 1 side or Urine leakage from the side portions 2 and 3 can be effectively prevented. 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 prevent the underwear, the sheets, or the disposable diapers that are repeatedly mounted from being stained. When the absorbent article 100 is replaced, the replacement work can be easily completed without soiling the hands by pulling out the leakage prevention sheet 20 while holding the sheet.

  As described above, since the absorbent article 100 of the present invention is intended to be used while being sandwiched between the inseam of the wearer, the front body and the back thereof cover the abdomen of the wearer like a conventional urine absorbing pad. It is not necessary to cover the back. Therefore, as shown in FIG. 1, it is sufficient that the overall length L of the absorbent article 100 of the present invention in the depth direction (D) is 80 mm to 250 mm, or 100 mm to 200 mm. According to the present invention, such a compact absorbent article can be realized.

  FIGS. 5A to 5E show an example of a manufacturing process of the absorbent article 100 according to the first embodiment. FIG. 5 shows a cross-sectional view taken along the line VV together with each figure. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 5A to 5E. That is, first, a rectangular outer sheet 11 is prepared (FIG. 5A). At this time, the through-hole 7 is not formed in the outer sheet 11. Next, on the non-skin-facing surface side of the outer sheet 11, the rectangular absorber 13 having the through-hole 7 is placed, and further, the inner sheet 12 is placed on the non-skin-facing surface side of the absorber 13. (FIG. 5B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. The absorber 13 may be joined to both or any one of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent main body 10 is obtained. At this stage, the through holes 7 are not formed in the outer sheet 11. Next, the absorbent main body 10 is folded in two toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 5C). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through-hole 7 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 same position as the through-hole 7 of the absorber 13 is cut off, so that the outer sheet 11 and the inner sheet 12 are almost simultaneously. Through holes 7 can be formed. Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 5E). In addition, a step of forming a mountain fold 8 (or a valley fold 9 described later) may be added to an appropriate position of the absorbent main body 10 constituting the absorbent article 100. Further, a step of bonding the end on the opposite side to the apex of the two-fold (that is, the end on the side where the leak-proof sheet 20 is disposed) with a hot melt adhesive or the like may be added.

  By following the above manufacturing process, the absorbent article 100 in which the through holes 7 are formed can be manufactured efficiently. Further, as shown in FIG. 5C, after the through hole 7 is formed in the absorber 13, the entirety of the absorbent main body 10 is folded in two along the through hole 7, so that the The creases on the top surface 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 be a flat surface and no folds remain. However, by forming the folds that occur during manufacturing along the through holes 7, the folds formed on the top surface portion 1 can be minimized. Limit. Thus, it is possible to make the fold hardly remain on the top surface portion 1 when worn.

[2. Second Embodiment]
Subsequently, a second embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the second embodiment, the description of the same configuration as the above-described embodiment will be omitted, and the description will focus on the configuration that is different from the above-described embodiment.

  FIG. 6 is an exploded perspective view of the absorbent article 100 according to the second embodiment, and FIG. 7 is a cross-sectional view of the absorbent article 100 according to the second embodiment. As shown in FIGS. 6 and 7, the absorbent article 100 according to the second embodiment further includes a sub-absorber 14 in addition to the components described in the first embodiment.

  As shown in FIG. 7, in the present embodiment, the sub-absorber 14 is arranged on the top surface 1 of the absorbent main body 10. In particular, the sub-absorber 14 is disposed on the non-skin-facing side of the absorber 13 (main absorber), that is, between the absorber 13 and the inner sheet 12. Note that the sub-absorber 14 may be made of an absorbent material and a core wrap sheet as in the case of the absorber 13. As in the present embodiment, by superimposing the absorber 13 and the sub-absorber 14 on the top surface 1, the amount of body fluid absorbed by the top surface 1 increases. For this reason, it can be said that this embodiment is a form for women who have a large amount of bodily fluid in direct contact with the top surface portion 1. When the sub-absorber 14 is disposed on the top surface 1, the through-hole 7 is also formed in the sub-absorber 14. Although not shown, the sub-absorber 14 can also be arranged on the skin-facing surface side of the absorber 13 (main absorber), that is, between the absorber 13 and the outer sheet 11.

  FIGS. 8A to 8E show an example of a manufacturing process of the absorbent article 100 according to the second embodiment. FIG. 8 shows a cross-sectional view taken along the line VIII-VIII along with each figure. First, a rectangular outer sheet 11 is prepared, and an absorbent body 13 (main absorbent body) having a through hole 7 formed on the non-skin-facing surface side is placed (FIG. 8A). Next, the sub-absorber 14 in which the through-hole 7 is formed is further overlapped with the absorber 13 at a position corresponding to the top surface portion 1 on the non-skin-facing surface side (FIG. 8B). At this time, the positions of the through holes 7 of the absorber 13 and the sub absorber 14 are aligned. Further, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13 and the sub-absorber 14. Thereby, the absorbent main body 10 is obtained. Next, the absorbent main body 10 is folded in half toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 8C). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through-hole 7 is located is cut off, and the outer sheet 11 and the inner sheet 12 are also formed with the through-hole 7 having substantially the same shape as the absorber 13 and the sub-absorber 14 (FIG. 8). (D)). Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 8E). In addition, a step of forming a mountain fold 8 (or a valley fold 9 described later) may be added to an appropriate position of the absorbent main body 10 constituting the absorbent article 100.

[3. Third Embodiment]
Subsequently, a third embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. 9 to 11. Regarding the third embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration that is different from the above-described embodiment.

  FIG. 9 is an exploded perspective view of the absorbent article 100 according to the third embodiment, and FIG. 10 is a cross-sectional view of the absorbent article 100 according to the third embodiment. As shown in FIGS. 9 and 10, the absorbent article 100 according to the third embodiment further has two sub-absorbers 14 in addition to the components described in the first embodiment. .

  As shown in FIG. 10, in this embodiment, the sub-absorbers 14 are arranged on the left and right side surfaces 2 and 3 of the absorbent main body 10 one by one. In particular, the two sub-absorbers 14 are arranged on the non-skin facing side of the absorber 13 (main absorber), that is, between the absorber 13 and the inner sheet 12. Note that each sub-absorber 14 may be made of an absorbent material and a core wrap sheet as in the case of the absorber 13. By overlapping the absorber 13 and the sub-absorber 14 on the left and right side portions 2 and 3 as in the present embodiment, the amount of body fluid absorbed by the side portions 2 and 3 increases. In particular, the body fluid introduced into the space 4 through the through hole 7 of the top surface portion 1 can be absorbed in a large amount by the sub-absorbers 14 arranged on the side surfaces 2 and 3. For this reason, it can be said that the present embodiment is directed to a man who inserts the penis into the through hole 7 of the top surface 1 and uses the penis. In addition, as shown in FIG. 10, it is preferable that the sub-absorber 14 is disposed on the absorber 13 at least on the lower end 5 side of the left and right side surfaces 2 and 3. However, the sub-absorber 14 may be disposed over the absorber 13 over the entire left and right side surfaces 2 and 3. Although not shown, the sub-absorber 14 can also be arranged on the skin-facing surface side of the absorber 13 (main absorber), that is, between the absorber 13 and the outer sheet 11.

  FIGS. 11A to 11E show an example of a manufacturing process of the absorbent article 100 according to the third embodiment. FIG. 11 shows a cross-sectional view taken along the line XI-XI together with each figure. First, a rectangular outer sheet 11 is prepared, and the absorber 13 (main absorber) having the through-hole 7 formed on the non-skin-facing surface side is placed (FIG. 11A). Next, the sub-absorbers 14 are further stacked one by one at positions corresponding to the side surfaces 2 and 3 on the non-skin facing side of the absorber 13 (FIG. 11B). Further, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13 and the sub-absorber 14. Thereby, the absorbent main body 10 is obtained. Next, the absorbent main body 10 is folded in two toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 11C). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through hole 7 is located is cut off, and the outer sheet 11 and the inner sheet 12 are also formed with the through hole 7 having substantially the same shape as the absorber 13 (FIG. 11D). Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 11E). In addition, a step of forming a mountain fold 8 (or a valley fold 9 described later) may be added to an appropriate position of the absorbent main body 10 constituting the absorbent article 100.

[4. Modified example of absorbent article]
Subsequently, a modified example of the absorbent article will be described with reference to FIGS. The modification described here can be applied to any of the above-described embodiments. In the drawings after FIG. 12, the cross-sectional shape of the absorbent main body 10 is simplified.

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

  FIG. 12C shows an example in which the cross-sectional shape of the absorbent main body 10 is substantially a water drop shape. In the case of this example, the absorbent main body 10 has no folds (mountain folds and valley folds), is curved by utilizing the flexibility of the absorbent main body 10, and has both left and right end portions of the leak-proof sheet. 20 bound. Therefore, the top surface portion 1 of the absorbent main body 10 having a surface that comes into contact with the wearer's crotch swells toward the wearer's skin side as a whole, and FIG. 12 (a) and FIG. It does not have a flat surface as in the example shown in b). In addition, as in the example shown in FIG. 12C, when no fold is formed as a boundary line between the top surface 1 and the left and right side surfaces 2 and 3, the width of the absorbent main body 10 in a natural state. The region up to the region having the maximum width in the direction may be defined as the top surface portion 1. The leakage prevention sheet 20 is attached to the lower end portions 5 of the left and right side surfaces 2 and 3 so as to straddle the side surfaces 2 and 3. Such a water-drop-shaped absorbent main body 10 has advantages that it has a high cushioning property and has no irregularities, so that it has a good touch and does not easily give a mechanical stimulus to the wearer's skin.

  FIG. 12D illustrates an example in which the cross-sectional shape of the absorbent main body 10 is substantially circular in the upper part and substantially rectangular in the lower part. In the case of this example, a valley fold 9 is formed in the liquid absorbing portion 6 of the left and right side portions 2 and 3 in the absorbent main body 10. In a region above the valley fold 9, no fold is formed, and the region is curved by utilizing the flexibility of the absorbent main body 10, and has a substantially circular cross section. For this reason, the top surface part 1 of the absorbent main body 10 is entirely swelled toward the skin side of the wearer, and does not have a flat surface. On the other hand, in the region below the valley fold 9, the left and right side portions 2, 3 abut in a palm-to-shape manner and extend straight. The portions where the left and right side portions 2 and 3 come into contact can be joined with a hot melt adhesive or the like. In addition, a portion where the left and right side portions 2 and 3 come into contact functions as a handle when the absorbent article 100 is inserted into and pulled out of the wearer's crotch. For example, in the example illustrated in FIG. 12D, the leak-proof sheet 20 extends longer upward and is easier to grasp as compared with other examples. 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 the case of this example, the absorbent main body 10 is completely cylindrical. Further, a leak-proof sheet 20 is attached to a part of the outer surface of the absorbent main body 10. The portion provided with the leak-proof sheet 20 is defined as the lower end portion 5 of the left and right side portions 2 and 3, and the portion opposite to the lower end portion 5 is defined as the top surface portion 1. The region between them is referred to as a liquid absorbing portion 6.

  FIG. 13B shows an example in which the cross-sectional shape of the absorbent main body 10 is substantially inverted Ω. In this example, the absorbent main body 10 has a top surface portion 1 having a surface in contact with a wearer's crotch, and is divided right and left at a split 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 non-skin-facing surface side of the top surface portion 1. A space 4 is formed between the left and right side portions 2 and 3. The split 7 ′ in the top surface 1 communicates with the space 4 between the left and right side surfaces 2, 3. For this reason, it can be said that the fracture 7 ′ has the same function as the through hole 7 described above. A valley fold 9 is formed on the boundary between the top surface 1 and the left and right side surfaces 2 and 3. Further, the left and right side portions 2 and 3 are integrally connected at their lower ends, and a mountain fold 8 (return line) is formed on the boundary between the left and right side portions 2 and 3. For this reason, the lowermost part of the absorbent main body 10 is in a closed state. In other words, the absorbent main body 10 is folded at the center in the width direction to form a mountain fold 8 (return line), and is further bent in opposite directions on both 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 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 crack 7 ′ of the top surface portion 1 or to insert the penis into the space 4 for use, the facing surfaces of the left and right side portions 2 and 3 should not be joined. Or partial bonding is preferred. The leakage prevention sheet 20 is attached to the lower end portions 5 of the left and right side surfaces 2 and 3 so as to straddle the side surfaces 2 and 3. At this time, a fold corresponding to the mountain fold 8 (return line) on the boundary between the left and right side portions 2 and 3 may also be formed on the leakproof sheet 20. In the example shown in FIG. 13B, even a solid material can be stored in the space 4 between the left and right side portions 2 and 3. Therefore, it can be suitably used as a pad for storing and processing loose stool and the like.

  FIG. 13C is a further modified example of the example shown in FIG. In the example shown in FIG. 13C, the left side portion 2 and the right side portion 3 are separated at the lower end. That is, in this example, two absorbent main bodies 10 are used, the left top surface 1 and the left side surface 2 are formed by the first absorbent main body 10, and the right top surface 1 and the right side surface 3 Is formed in the second absorbent 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 at the lower end portion 5 by a leak-proof sheet 20, and these 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 in two layers on the top surface portion 1. That is, in this example, the absorbent main body 10 overlaps in two layers on the top surface portion 1, the upper layer portion is integrally connected to the left side portion 2, and the lower layer portion is integrally connected to the right side portion 3. A mountain fold 8 is formed on the boundary 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. The left and right side portions 2 and 3 are integrally connected at the lower end, and a mountain fold 8 is formed on the boundary between the two. For this reason, the cross-sectional shape of the absorbent main body 10 becomes a substantially inverted triangle. The leakage prevention sheet 20 is attached to the lower end portions 5 of the left and right side surfaces 2 and 3 so as to straddle the side surfaces 2 and 3. In the example shown in FIG. 14A, since the absorbent main body 10 overlaps in two layers on the top surface 1, the amount of body fluid absorbed on the top surface 1 can be increased.

  FIG. 14B shows an example in which the absorbent main body 10 constituting the top surface part 1 and the absorbent main body 10 constituting the left and right side surface parts 2 and 3 are separately provided. In this example, the left and right side portions 2 and 3 are constituted by a single absorbent main body 10, and the absorbent main body 10 is bent at a mountain fold 8 at a lower end to have a substantially V shape. On the other hand, the absorbent main body 10 constituting the top surface portion 1 is bent toward the left and right sides and inward in the width direction and overlapped on the outer surface of the upper end portions of the left and right side portions 2 and 3. Join with. The top surface part 1 can be flat without any folds. In this manner, the top surface portion 1 and the left and right side surface portions 2 and 3 can be constituted by separate absorbent main bodies 10. The leak-proof sheet 20 is attached to the lower end portions 5 of the left and right side portions 2 and 3 so as to straddle the respective side 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 in 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 8. On the other hand, the portion forming the left side portion 2 is folded inward at the lower end, and the portion forming the right side portion 3 is further bent inward at the lower end and partially overlaps the outer surface of the left side portion 2. . In this manner, the lower ends of the left and right side portions 2 and 3 can be folded back to be stacked 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 to the lower end portions 5 of the left and right side portions 2 and 3 so as to straddle the respective side 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-sectional shape, and the end seam of the absorbent main body 10 is located at the right side surface portion 3 (or the left side surface portion 2). Is shown. That is, in this example, the top surface 1 and the left and right side surfaces 2 and 3 are integrally connected via the mountain fold 8. The left and right side portions 2 and 3 are also integrally connected at the lower end, and a mountain fold 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 leakage prevention sheet 20 is provided so as to cover the joint. For this reason, in this example, the leakage prevention sheet 20 is attached only to a portion corresponding to the right side surface portion 3 of the absorbent main body 10. As described above, the leakage prevention sheet 20 is not limited to the lower end of the absorbent main body 10 and may be attached to at least a part of the outer surface of the absorbent main body 10.

  In the examples shown in FIGS. 12 to 14, the illustration of the through holes 7 in the top surface 1 is omitted. In the example shown in FIGS. 12 to 14, similarly to the above-described first to third embodiments, it is possible to form the through-hole 7 connected to the internal space 4 in the top surface 1 of the absorbent main body 10. It is possible.

As described above, in a state where the top surface 1 of the absorbent main body 10 is covered by a part (extending portion 22) of the leak-proof sheet 20 in a state of being housed in the package 200, the sanitary state of the top surface 1 is reduced. Can be kept. As shown in FIG. 16, in the leakage prevention sheet 20, a perforation 23 is formed between the fixing portion 21 and the extending portion 22, and the fixing portion 21 and the extending portion are formed along the perforation 23. 22 may be separated. At the time of use, the extension portion 22 is separated from the fixed portion 21 and discarded, so that the extension portion 22 does not interfere.

[6. Further Modification of Absorbent Article]
FIG. 17 is a plan view showing a further modified example of the absorbent article. FIG. 18 is a cross-sectional view schematically showing a cross-sectional shape along 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) to finally reach the state shown in (c). In the deployed state shown in FIG. 17A, the absorbent main body 10 includes a front side 10a located on the front side (abdomen of the wearer) in the depth direction (D) and a rear side on the depth direction (D). (A back side of the wearer) and a central portion 10c located therebetween. In the example shown in FIG. 17, when the overall length in the depth direction (D) of the absorbent main body 10 is 100%, the length of the central portion 10c is about 10% to 50%, and the remaining length is about 10% to 50%. The length is bisected by the front side 10a and the rear side 10b. Further, the front side portion 10a and the rear side portion 10b of the absorbent main body 10 are longer in the width direction (W) than the central portion 10c. In other words, the absorptive main body 10 has left and right flap portions 10L, 10R extending in the width direction (W) left and right outer sides of the central portion 10c on both the front side portion 10a and the rear side portion 10b. I have. For this reason, the absorbent main body 10 has a substantially hourglass-like shape in plan view. In the example shown in FIG. 17, the right flap R extends longer from the center 10c toward the outside in the width direction (W) than the left flap L.

  Further, as shown in FIG. 17A, the squeezing lines 13 c may be formed in the absorber 13 of the absorbent main body 10 in an oblique lattice pattern. The compression line 13c is formed by pressing the absorber 13 from one or both of the skin-facing surface side and the non-skin-facing surface side, and a concave portion is formed on the absorber 13 along the compression line 13c. Will be formed. In addition, the rhombic lattice-like pattern is defined by a plurality of squeezing 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, and intersects with the rhombic ( (Diamond) refers to a pattern in which a non-squeezed area is defined. As described above, by forming the plurality of compressed lines 13c on the absorber 13, the diffusibility of the bodily fluid in contact with the surface of the absorber 13 can be enhanced, and the strength and the shape retention of the entire absorbent body 10 can be improved. Can be enhanced. Although not shown, the absorbent 13 may be formed with the pressing lines 13c in a rectangular lattice pattern. The rectangular lattice pattern referred to herein is that a plurality of squeezing lines 13c extending parallel to the depth direction and a plurality of squeezing lines 13c extending parallel to the width direction intersect to define a rectangular (square) non-squeezed region. Refers to the pattern that is performed.

  Next, as shown in FIG. 17 (b), the portion 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 inward in the width direction (W). Fold it back to the opposite side. Thereafter, as shown in FIG. 17 (c), the portion of the absorbent main body 10 including the right flap portion 10R in the front side portion 10a and the rear side portion 10b faces the skin inward in the width direction (W). Fold it 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. 17C, in the central portion 10c of the absorbent main body 10, the through hole 7 is provided between the flap portions 10L, 10R of the front side portion 10a and the flap portions 10L, 10R of the rear side portion 10b. Is formed. The through hole 7 has a function corresponding to the through hole 7 in each of the above-described embodiments.

  FIG. 18 shows a cross-sectional shape of the state shown in FIG. As shown in FIG. 18, even when the absorbent main body 10 is bent in accordance with the steps shown in FIGS. Can be obtained. As shown in FIG. 18, the left and right flap portions 10L and 10R of the front side portion 10a and the rear side portion 10b form the top surface 1 of the absorbent main body 10. Further, a through hole 7 communicating with the internal space is formed in the top surface portion 1. In addition, inner portions in the width direction of the left and right flap portions 10L and 10R form left and right side surface portions 2 and 3 of the absorbent main body 10. At the center in the width direction of the absorbent main body 10, a mountain fold 8 is formed along the depth direction. Further, a leak-proof sheet 20 is attached to the lower end 5 of the side portions 2 and 3 of the absorbent main body 10 so as to straddle the left and right side portions 2 and 3. Thus, the absorbent article 100 having a three-dimensional shape having the through-holes 7 in the top surface 1 can be obtained also by the method shown in FIG.

[7. Fourth embodiment]
Subsequently, a fourth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the fourth embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration that is 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 shown in FIG. 19, the absorbent article 100 according to the present invention has a tubular three-dimensional shape having a space 4 therein. In the present embodiment, the back surface sides of both ends of one planar rectangular absorbent main body 10 are formed into a cylindrical shape having a space 4 extending along the depth direction (D) with the back sides facing each other. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface in contact with a wearer's crotch, and left and right side surface portions 2 extending from both left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (left side surface 2 and right side surface 3) and a space 4 formed between the left and right side surfaces 2 and 3. The space 4 penetrates along the depth direction (D) from the abdominal end of the wearer to the dorsal end. Furthermore, a liquid-impermeable leakproof sheet 20 is attached to the lower end 5 of the left and right side surfaces 2 and 3 of the absorbent main body 10. The leakage prevention sheet 20 is joined across the left and right side parts 2 and 3 and also has a function of connecting the side parts 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.

  FIG. 20 is an exploded perspective view of the absorbent article 100, and FIG. 21 is a 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 portion thereof.

  20, 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, and its lower end is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leak-proof sheet 20 has a cylindrical three-dimensional shape as shown in FIGS. 19 and 21. Further, as shown in FIG. 21, a leak-proof sheet 20 is provided at the lower end 5 of the absorbent main body 10 across the left side surface 2 and the right side surface 3. For this reason, it can be said that the leakage prevention sheet 20 has a function of connecting the left side part 2 and the right side part 3 of the absorbent main body 10.

  FIG. 22 shows an example of a state where the absorbent article 100 is sandwiched between the legs of a wearer. As shown in FIG. 22, of the absorbent main body 10, the top surface portion 1 forming a flat surface is in close contact with the wearer's crotch, and the side surface portions 2 and 3 located on the left and right sides thereof are attached to the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side portions 2, 3, the absorbent main body 10 has a high cushioning property as a whole, and the close contact with the crotch and the inner thigh is maintained. Thereby, a gap is less likely to be formed between the absorbent main body 10 and the wearer's skin, and even when worn on a wearer in a lateral or semi-lateral position, the top surface 1 side or Urine leakage from the side portions 2 and 3 can be effectively prevented. 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 prevent the underwear, the sheets, or the disposable diapers that are repeatedly mounted from being stained. When the absorbent article 100 is replaced, the replacement work can be easily completed without soiling the hands by pulling out the leakage prevention sheet 20 while holding the sheet.

  As shown in FIGS. 19 to 23, in the absorbent article 100 of the present invention, a plurality of compression lines 31, 32, and 33 are formed on the absorber 13. Each compression line is formed by partially depressing the absorber 13 in the thickness direction. In particular, each compression line can be formed by partially pressing and compressing the absorber 13 from both sides or any one of the skin-facing surface side and the skin non-facing surface side. For this reason, the density of the absorbent material 13a forming the absorber 13 is increased in the portion where the compression line is formed. As described above, by forming the compression line on the absorber 13, the absorber 13 is easily bent along the compression line. In addition, since the density of the absorbent material 13a is increased at the portion where the compression line is formed, the stress of the absorber 13 against external force applied in a direction parallel to the direction in which the compression line extends is improved. Moreover, since the absorber 13 is partially depressed at the portion where the compression line is formed, the body fluid flows along the compression line, and the body fluid is easily diffused in the extending direction of the compression line. In addition, the compression line may be formed on the skin-facing surface side of the absorber 13, may be formed on the non-skin-facing surface side, or may be formed on both sides thereof. Hereinafter, the pattern of the squeezed line formed on the absorber 13 will be described in more detail.

  FIG. 23 is a view for explaining the pattern of the squeezing line formed on the absorber 13, and shows a developed state of the absorber 13. As shown in FIG. 23, a first compression line 31 extending in the width direction is formed on the absorbent body 13 at a portion corresponding to the top surface portion 1 of the absorbent main body 10. A plurality of first compression lines 31 are formed at predetermined intervals in the depth direction, and each of the first compression lines 31 is a straight line parallel to the width direction. The interval between the plurality of first squeezing lines 31 is not particularly limited. For example, the interval between the first squeezing lines 31 is preferably 3 mm to 30 mm or 5 mm to 20 mm. Basically, the first compression line 31 extends over the entire area of the top surface 1 in the width direction. That is, the first compression line 31 preferably reaches the boundary between the top surface 1 and the left side surface 2 and the boundary between the top surface 1 and the right side surface 3. As described above, the through-hole 7 is formed in the top surface 1. In this case, it is preferable that the first compression line 31 reaches the periphery of the through hole 7.

  As described above, by forming the plurality of first compression lines 31 along the width direction on the top surface portion 1, the stress of the top surface portion 1 against external force applied from the width direction can be increased. By improving the stress of the top surface portion 1, the top surface portion 1 and the space 4 located below the top surface portion 1 are less likely to be crushed. Shape can also be retained. In addition, by forming the first compressed line 31 extending in the width direction on the top surface 1 of the absorber 13, the body fluid that has touched the top surface 1 is easily diffused in the width direction. As a result, the body fluid can be rapidly absorbed in a wide range from the top surface portion 1 to the side surface portions 2 and 3, and the effect of preventing urine leakage can be enhanced.

  Further, as shown in FIG. 23, the absorber 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 fold 8). A second squeeze line 32 is formed. Therefore, the absorbent main body 10 is bent along the second compression line 32 formed on the absorber 13. That is, the mountain fold 8 of the absorbent main body 10 has a shape corresponding to the second compression line 32 of the absorber 13. As shown in FIG. 23, the second compression line 32 extends over substantially the entire region in the depth direction of the absorber 13. For example, when the length in the depth direction of the absorber 13 is 100%, the second compression line 32 extends over a length range of 80 to 100% or 90 to 100% in the depth direction. Is preferred.

  Each of the pair of left and right second compressed lines 32 is formed in an arc shape projecting outward in the width direction. That is, the interval between the pair of left and right second compressed lines 32 is the narrowest at the front end portion and the rear end portion in the depth direction, and is widest at the center portion in the depth direction. In this manner, by forming the left and right second compressed lines 32 in an arc shape, the top surface 1 that is a region between the second compressed lines 32 has a substantially elliptical shape in plan view. Then, when the top surface portion 1 is defined by the arc-shaped second compression line 32, when the absorbent main body 10 is bent along the second compression line 32, the top surface portion 1 becomes as shown in FIG. 19. In addition, the front end portion and the rear end portion in the depth direction are shaped to rise. That is, in the state where the absorbent main body 10 has a cylindrical three-dimensional shape as shown in FIG. 19, both ends of the front end in the depth direction of the top surface portion 1 are located above the center portion in the depth direction. I do. By making the second pressing line 32 into an arc shape, such a state of the top surface portion 1 can be naturally held. The front end portion of the top surface portion 1 in the depth direction is thinner than the center portion and rises upward, so that it fits properly on the lower abdomen of the wearer. In addition, the rear end portion of the top surface 1 in the depth direction is thinner than the central portion, and moreover, rises upward, so that it fits appropriately to the buttocks of the wearer. Thereby, leakage of urine and stool can be more effectively prevented.

  As shown in FIGS. 19 and 23, the first compression line 31 is formed from the second compression line 32 on the left side to the second compression line 32 on the right side, or has a through hole at the center. It is formed from the hole 7 to the left and right second pressing lines 32. As described above, by forming the first compression line 31 over substantially the entire area of the top surface 1 in the width direction, the shape of the top surface 1 defined by the second compression line 32 can be maintained. . That is, since the density of the absorbent material is high at the portion where the first compression line 31 is formed, the absorber 13 has a strong stress against external pressure from the width direction. Therefore, even when the top surface portion 1 defined by the second compression line 32 is sandwiched between the legs of the wearer, the top surface portion 1 hardly collapses due to the action of the first compression line 31 and has a flat state. Can be maintained.

  Further, as shown in FIG. 23, a plurality of third squeezing lines 33 extending in the depth direction are formed on each of the left side surface portion 2 and the right side surface portion 3 in the absorber 13. The plurality of third squeezing lines 33 include an arc-shaped squeezing line 33a that protrudes in the same direction as the second squeezing line 32 in a deployed state, and a linear squeezing line 33b that extends parallel to the depth direction. It is. It can be said that the arc-shaped squeezing line 33a has an arc shape that protrudes downward when the absorbent main body 10 has a cylindrical three-dimensional shape (see FIG. 19). By forming the arc-shaped compression lines 33a on the left and right side portions 2 and 3 in this way, the top surface portion 1 bends in the depth direction and deforms necessary to become three-dimensional. , 3 so that no gap is formed between the top surface portion 1 and the lower abdomen or buttocks of the wearer, so that leakage can be prevented. Further, in a region between the arc-shaped compression line 33a and the second compression line 32, the left and right side portions 2 and 3 can easily maintain a state of being swelled outward. Since the internal space 4 is widely secured, a large amount of urine and stool can be collected. Further, by forming the linear compression lines 33b on the left and right side portions 2 and 3, it is possible to improve the stress against external pressure from the depth direction. The arc-shaped compression line 33a and the linear compression line 33b included in the third compression line 33 are similar to the second compression line 32 when the length in the depth direction of the absorber 13 is 100%. , Preferably extending over a length range of 80 to 100% or 90 to 100% in the depth direction.

  FIGS. 24A to 24E show an example of a manufacturing process of the absorbent article 100 according to the fourth embodiment. FIG. 24 shows a cross-sectional view taken along the line XXIV-XXIV along with each figure. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 24 (a) to 24 (e). That is, first, a rectangular outer sheet 11 is prepared (FIG. 24A). At this time, the through-hole 7 is not formed in the outer sheet 11. Next, on the non-skin-facing surface side of the outer sheet 11, the rectangular absorber 13 having the through-hole 7 is placed, and further, the inner sheet 12 is placed on the non-skin-facing surface side of the absorber 13. (FIG. 24B). At this stage, a plurality of squeezing lines 31, 32, and 33 are formed in the absorber 13 in the pattern described above. In addition, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. The absorber 13 may be joined to both or any one of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent main body 10 is obtained. At this stage, the through holes 7 are not formed in the outer sheet 11. Next, the absorbent main body 10 is folded in half toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 24C). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through-hole 7 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 same position as the through-hole 7 of the absorber 13 is cut off, so that the outer sheet 11 and the inner sheet 12 are almost simultaneously. Through holes 7 can be formed. Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 24 (e)). In addition, a step of forming the mountain fold 8 may be added at a position where the arc-shaped second compression line 32 is formed on the absorber 13. Further, a step of bonding the end on the opposite side to the apex of the two-fold (that is, the end on the side where the leak-proof sheet 20 is disposed) with a hot melt adhesive or the like may be added.

  By following the above manufacturing process, the absorbent article 100 in which the through holes 7 are formed can be manufactured efficiently. Further, as shown in FIG. 24 (c), after the through-hole 7 is formed in the absorber 13, the entirety of the absorbent main body 10 is folded in two along the through-hole 7, so that the The creases on the top surface 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 be a flat surface and no folds remain. However, by forming the folds that occur during manufacturing along the through holes 7, the folds formed on the top surface portion 1 can be minimized. Limit. Thus, it is possible to make the fold hardly remain on the top surface portion 1 when worn.

[8. Fifth Embodiment]
Subsequently, a fifth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the fifth embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration that is 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 absorber 13 has a structure in which the main absorber 13 and the sub-absorber 14 are laminated.

  As shown in FIG. 26, in this embodiment, the main absorber 13 is located on the top surface 1 and the left and right side surfaces 2 and 3 of the absorbent main body 10. That is, the main absorber 13 in the fifth embodiment has substantially the same configuration as the absorber 13 in the above-described fourth embodiment. On the other hand, the sub-absorber 14 is arranged only on the top surface 1 of the absorbent main body 10. In particular, the sub-absorber 14 is disposed on the non-skin-facing surface side of the main absorber 13, that is, between the main absorber 13 and the inner sheet 12. The sub-absorber 14 may be made of an absorbent material and a core wrap sheet as in the case of the main absorber 13. As in the present embodiment, by superimposing the main absorber 13 and the sub-absorber 14 on the top surface 1, the amount of body fluid absorbed by the top surface 1 increases. For this reason, it can be said that this embodiment is a form for women who have a large amount of bodily 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. Although not shown, the sub-absorber 14 may be disposed on the skin-facing surface side of the main absorber 13, that is, between the main absorber 13 and the outer sheet 11.

  Further, as shown in FIGS. 25 and 26, in the present embodiment, a first compression line 31 extending along the width direction is formed on the sub-absorber 14 located on the top surface 1. A plurality of first compression lines 31 are formed at predetermined intervals in the depth direction, and each of the first compression lines 31 is a straight line parallel to the width direction. The operation of the first squeezing line 31 formed on the top surface 1 is as described above. In other words, by forming the plurality of first compression lines 31 on the sub-absorbent body 14 located on the top surface portion 1, the stress against external force in the width direction increases, and the first compression lines 31 allow the body fluid to be spread widely and quickly. Can be spread.

  In the present embodiment, a plurality of third compression lines 33 extending in the depth direction are formed on each of the left side surface portion 2 and the right side surface portion 3 in the main absorber 13. The third squeezing line 33 formed on the main absorber 13 is formed in a straight line extending parallel to the depth direction. By forming the linear third compression lines 33 on the left and right side portions 2 and 3, it is possible to improve stress against external pressure from the depth direction.

  As described above, in the present embodiment, the first compression line 31 extending in the width direction is formed on the sub-absorber 14, and the third compression line 33 extending in the depth direction is formed on the main absorber 13. However, for example, it is also possible to form both the first compression line 31 extending in the width direction and the third compression line 33 extending in the going direction on the main absorber 13.

[9. Sixth Embodiment]
Subsequently, a sixth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIG. 27 and FIG. FIG. 27 is an exploded perspective view of the absorbent article 100 according to the sixth embodiment, and FIG. 28 is a developed 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 is different 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 in a circular (or elliptical) shape in plan view. For this reason, as shown in the plan view of FIG. 28A, the absorbent main body 10 in which the absorber 13 is laminated between the outer sheet 11 and the inner sheet 12 also has a circular outer shape in plan view in the unfolded state. (Or elliptical). Further, as shown in the side view of FIG. 28 (b), the lower end portion 5 of the left and right side portions 2, 3 of the absorbent main body 10 is provided with the leak-proof sheet 20 straddling the left and right side portions 2, 3. It is attached. As described above, by molding the absorbent main body 10 into a circular shape, it is possible to eliminate corners below the front end portion and the rear end portion in the depth direction as compared with the case where the absorbent main body 10 is molded into a rectangular shape. For this reason, the size of the entire absorbent article 100 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 formed in a rectangular shape, corners will remain below the front end part and the rear end part in the depth direction, and these corners will be caught by underwear or the like, and the absorbent article 100 will be crotch. It may be difficult to pinch. On the other hand, by molding the absorbent main body 10 into a circular shape as in the present embodiment, the lower edge of the front end portion and the lower edge of the rear end portion in the depth direction are formed in an arc shape, so that it is hard to be caught by clothes when worn. It can be attached and detached smoothly. Note that whether the outer shape of the absorbent main body 10 is rectangular (fourth embodiment) or circular (sixth embodiment) may be appropriately changed according to the use of the absorbent article 100.

[10. Seventh embodiment]
Subsequently, a seventh embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the seventh embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration that is different from the above-described embodiment.

  FIG. 29 is a perspective view showing an outline of the absorbent article 100 according to the present invention. As shown in FIG. 29, the absorbent article 100 according to the present invention has a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back surface sides of both ends of one planar rectangular absorbent main body 10 are formed into a cylindrical shape having a space 4 extending along the depth direction (D) with the back sides facing each other. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface in contact with a wearer's crotch, and left and right side surface portions 2 extending from both left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (left side surface 2 and right side surface 3) and a space 4 formed between the left and right side surfaces 2 and 3. The space 4 penetrates along the depth direction (D) from the abdominal end of the wearer to the dorsal end. Furthermore, a liquid-impermeable leakproof sheet 20 is attached to the lower end 5 of the left and right side surfaces 2 and 3 of the absorbent main body 10. The leakage prevention sheet 20 is joined across the left and right side parts 2 and 3 and also has a function of connecting the side parts 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.

  FIG. 30 is an exploded perspective view of the absorbent article 100, and FIG. 31 is a 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 a lower portion thereof.

  As shown in FIG. 30, the absorber 13 has a lattice-shaped squeezing line 41 formed at least on the top surface 1. The compression line 41 is a linear concave portion formed by partially compressing the absorber 13. The lattice shape means a state in which a group of a plurality of compressed lines extending in a certain direction intersects with a group of a plurality of compressed lines extending in a different direction. The pressing lines 41 may be formed in a rhombic lattice pattern as shown in FIG. 30 and the like, or may be formed in a square lattice pattern. That is, the lattice-shaped squeezing lines 41 extend at least along the width direction (W) of the absorbent article, or along the direction inclined at 1 to 45 degrees with respect to the width direction (W). Extensions are included. 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, and particularly 30 to 45 degrees, or 35 to 45 degrees. Is preferred.

  In addition, the compression line 41 can be basically formed by compressing the absorber 13 from the side facing the skin. However, the squeezing line 41 may be formed by compressing the absorber 13 from the non-skin-facing surface side, or compressing the absorber 13 from both sides of the skin-facing surface and the non-skin-facing surface. May be formed. As described above, since the compression line 41 is formed by compressing the absorber 13, the strength of the absorber 13 is improved at the portion (top surface portion 1) where the compression line 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 in a predetermined range with respect to the width direction (W). Is included. For this reason, it can be said that the stress with respect to the external force in the width direction of the absorber 13 is improved at the portion of the top surface 1 where the compression line 41 is formed.

  As shown in FIG. 29 and FIG. 30, the stress of the top surface portion 1 is increased by forming the lattice-shaped squeezing lines 41 on the absorber 13 at a portion corresponding to the top surface portion 1 of the absorbent article 100. Therefore, even when the absorbent biological product 100 is sandwiched between the legs of the wearer, 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 is maintained. can do. This makes it easier for the absorbent article 100 to adhere to the wearer's crotch and inner thigh. Further, by forming the lattice-shaped compression lines 41 on the top surface 1 of the absorber 13, the bodily fluid that has touched the top surface 1 is easily diffused along the compression lines 41. As a result, the body fluid can be rapidly absorbed in a wide range from the top surface portion 1 to the side surface portions 2 and 3, and the effect of preventing urine leakage can be enhanced.

  In the example shown in FIGS. 29 and 30, the compression line 41 is formed only in the top surface 1 of the absorber 13. However, in the present invention, the pressing line 41 may be formed at least on the top surface 1, may be formed on the left and right side surfaces 2, 3, or may be formed on the entire absorber 13. Good.

  From the expanded state as shown in FIG. 30, the outer sheet 11, the inner sheet 12, and the absorber 13 are bonded to form the absorbent main body 10, and the left and right ends of the absorbent main body 10 in the width direction (W). Is bent toward the inner sheet 12, and the lower end thereof is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leak-proof sheet 20 has a tubular three-dimensional shape as shown in FIG. Further, as shown in FIG. 31, a leak-proof sheet 20 is attached to the lower end 5 of the absorbent main body 10 across the left side surface 2 and the right side surface 3. For this reason, it can be said that the leakage prevention sheet 20 has a function of connecting the left side part 2 and the right side part 3 of the absorbent main body 10.

  Further, as shown in FIGS. 29 and 30, it is preferable that the through-hole 7 is formed in a region of the top surface portion 1 where the lattice-shaped squeezing lines 41 are formed. That is, it is preferable that the periphery of the through hole 7 is surrounded by the compression line 41, and the compression line 41 reach the periphery of the through hole 7. That is, as shown in a partially enlarged view of FIG. 30, when the pressing line 41 reaches the edge of the through hole 7, a concave portion is also formed at the edge of the through hole 7. In addition, as described above, since the strength of the absorber 13 is improved in the region where the compression line 41 is formed, by providing the through-hole 7 in the region of the lattice-shaped compression line 41, Shape can be maintained. In the present invention, as described above, the lattice-shaped squeezing lines 41 are provided on the top surface portion 1 to increase rigidity in the width direction of the top surface portion 1 and prevent shape collapse. For this reason, even when the through-hole 7 is provided in the top surface portion 1, the through-hole 7 is less likely to be closed by the action of the squeezing wire 41, and can function as a hole.

  As described above, the through holes 7 are formed in all of the outer sheet 11, the inner sheet 12, and the absorber 13 that constitute the top surface section 1. For this reason, as shown in FIG. 31, the outer sheet 11 and the inner sheet 12 are formed along the contour 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 where the absorbent article 100 is sandwiched between the wearer's crotch. As shown in FIG. 32, of the absorbent main body 10, the top surface portion 1 forming a flat surface is in close contact with the wearer's crotch, and the side surface portions 2 and 3 located on the left and right sides thereof are attached to the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side portions 2, 3, the absorbent main body 10 has a high cushioning property as a whole, and the close contact with the crotch and the inner thigh is maintained. Thereby, a gap is less likely to be formed between the absorbent main body 10 and the wearer's skin, and even when worn on a wearer in a lateral or semi-lateral position, the top surface 1 side or Urine leakage from the side portions 2 and 3 can be effectively prevented. 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 prevent the underwear, the sheets, or the disposable diapers that are repeatedly mounted from being stained. When the absorbent article 100 is replaced, the replacement work can be easily completed without soiling the hands by pulling out the leakage prevention sheet 20 while holding the sheet.

  FIGS. 33A to 33E show an example of a manufacturing process of the absorbent article 100 according to the seventh embodiment. FIG. 33 shows a cross-sectional view taken along the line XXXIII-XXXIII along with each figure. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 33 (a) to 33 (e). That is, first, the rectangular outer sheet 11 is prepared, and the rectangular absorber 13 in which the through-hole 7 and the lattice-shaped squeezing line 41 are formed is placed on the non-skin facing side of the outer sheet 11 (FIG. 33 (a)). At this time, the through-hole 7 is not formed in the outer sheet 11. Next, the inner sheet 12 is placed on the non-skin facing side of the absorber 13 (FIG. 33B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. The absorber 13 may be joined to both or any one of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent main body 10 is obtained. At this stage, the through holes 7 are not formed in the outer sheet 11. Next, the absorbent main body 10 is folded in two toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 33 (c)). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through-hole 7 is located is cut off, and the outer sheet 11 and the inner sheet 12 are also formed with the through-hole 7 having substantially the same shape as the absorber 13 (FIG. 33D). At this time, since the outer sheet 11 and the inner sheet 12 overlap with the through-hole 7 of the absorber 13, the same position as the through-hole 7 of the absorber 13 is cut off, so that the outer sheet 11 and the inner sheet 12 are almost simultaneously. Through holes 7 can be formed. Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 33 (e)). In addition, a step of forming the mountain fold 8 may be added to an appropriate position of the absorbent main body 10 constituting the absorbent article 100. Further, a step of bonding the end on the opposite side to the apex of the two-fold (that is, the end on the side where the leak-proof sheet 20 is disposed) with a hot melt adhesive or the like may be added.

  By following the above manufacturing process, the absorbent article 100 in which the through holes 7 are formed can be manufactured efficiently. Further, as shown in FIG. 33 (c), after the through-hole 7 is formed in the absorber 13, the whole of the absorbent main body 10 is folded in two along the through-hole 7, so that the The creases on the top surface 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 be a flat surface and no folds remain. However, by forming the folds that occur during manufacturing along the through holes 7, the folds formed on the top surface portion 1 can be minimized. Limit. Thus, it is possible to make the fold hardly remain on the top surface portion 1 when worn.

[11. Eighth embodiment]
Next, an eighth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the eighth embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration different from 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 sub absorbent body 14 is disposed on the top surface 1 of the absorbent main body 10. In particular, the sub-absorber 14 is disposed on the non-skin-facing surface side of the absorber 13 (hereinafter also referred to as “main absorber”), that is, between the main absorber 13 and the inner sheet 12. Note that, similarly to the main absorber 13, the sub-absorber 14 may be made of an absorbent material 14a and a core wrap sheet 14b. As in the present embodiment, by superimposing the main absorber 13 and the sub-absorber 14 on the top surface 1, the amount of body fluid absorbed by the top surface 1 increases. For this reason, it can be said that this embodiment is a form for women who have a large amount of bodily fluid in direct contact with the top surface portion 1. When the sub-absorber 14 is disposed on the top surface 1, the through-hole 7 is also formed in the sub-absorber 14. By providing the top absorber 1 with the main absorber 13 and the sub absorber 14 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. Although not shown, the sub-absorber 14 can also be arranged on the skin-facing surface side of the main absorber 13, that is, between the absorber 13 and the outer sheet 11. In the present embodiment, the sub-absorber 14 may be disposed at least on the top surface 1, and may be disposed on the left and right side surfaces 2 and 3. However, as in the embodiment shown in FIG. 35, it is preferable that the sub-absorber 14 is disposed only on the top surface 1.

  FIGS. 36A and 36B show the main absorber 13 and the sub absorber 14 separately, and FIGS. 36C and 36D show cross-sectional shapes along XXXVI-XXXVI. . FIG. 37 shows a pattern of a compression line 41 formed on the main absorber 13 and a pattern of a compression line 51 formed on the sub-absorber 14 in a state where the main absorber 13 and the sub-absorber 14 are overlapped. Is enlarged. 36 and 37, only the main absorber 13 and the sub absorber 14 are conceptually extracted and shown.

  As shown in FIGS. 36 and 37, in the eighth embodiment, compression lines 41, 51 in which the absorbers 13, 14 are recessed in the thickness direction are respectively provided on the main absorber 13 and the sub absorber 14. Are formed. That is, a plurality of compression lines 41 and 51 are formed on each of the main absorber 13 and the sub absorber 14. The compression lines 41 and 51 are formed by partially pressing and compressing the compression lines 41 and 51 from both sides or any one of the skin-facing surface side and the non-skin-facing surface side. Therefore, the density of the absorbent material 13a, 14a in each of the absorbers 13, 14 increases in the portion where the compression lines 41, 51 are formed. The compression line 31 formed on the main absorber 13 and the compression line 51 formed on the sub-absorber 14 form a pattern that at least partially intersects each other when viewed from the plane. Hereinafter, the pattern of the compression line 41 formed on the main absorber 13 and the pattern of the compression line 51 formed on the sub-absorber 14 will be described in detail.

  As shown in FIG. 36, the squeezing lines 41 are formed in the main absorber 13 in an oblique lattice pattern. Here, the “rhombic lattice pattern” is a pattern in which a plurality of compression lines extending in a direction inclined with respect to the longitudinal direction and the width direction intersect to define a rhombic (rhombic) non-compressed 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 Preferably it is 35 degrees to 45 degrees. In particular, in the present embodiment, the pattern of the compression lines 41 in the main absorber 13 is a regular pattern (a regular rhombus) in which all the non-compression regions 42 surrounded on all sides by the compression lines 41 have a regular rhombus (regular rhombus) shape. (A square lattice pattern). As described above, the main absorbent body 13 is formed with a plurality of compression lines 41, a non-compression region 42 surrounded by the compression lines 41, and an intersection 43 where the compression lines 41 intersect. can do. Hereinafter, for convenience, the compression line 41 of the main absorbent body 13 is referred to as “upper compression line 41”, the non-compression region 42 is referred to as “upper non-compression region 42”, and the intersection 43 is referred to as “upper intersection portion 43”.

  On the other hand, the compressed lines 51 are formed in the sub-absorber 14 in a rectangular lattice pattern. The “square lattice pattern” here means that a plurality of squeezing lines extending parallel to the longitudinal direction and a plurality of squeezing lines extending parallel to the width direction intersect to define a square non-squeezed region. Refers to a pattern. In particular, in the present embodiment, the pattern of the compression lines 51 in the sub-absorber 14 is a regular pattern (a square lattice pattern) in which all the non-compression regions 52 surrounded on all sides by the compression lines 51 are square. Has become. As described above, also in the sub-absorber 14, a plurality of compressed lines 51, a non-compressed area 52 surrounded by the compressed lines 51, and an intersection 53 where the compressed lines 51 intersect are formed. can do. Hereinafter, for convenience, the compression line 51 in the sub-absorber 14 is referred to as a “lower compression line 51”, the non-compression region 52 is referred to as a “lower non-compression region 52”, and the intersection 53 is referred to as a “lower intersection 53”. .

  In the present embodiment, the upper compression line 41 is formed by compressing and denting the main absorbent body 13 from the skin-facing surface side. Similarly, the lower compression line 51 is formed by compressing and denting the sub-absorbent body 14 from the skin-facing surface side. For this reason, a gap is formed between the main absorber 13 and the sub-absorber 14 in a state where the lower compression line 51 is formed in the sub-absorber 14 in a state where the lower compression line 51 is formed.

  As shown in FIG. 37, in the present embodiment, the upper intersection 43 of the main absorber 13 and the lower intersection 53 of the sub-absorber 14 overlap each other when the absorbers 13 and 14 are overlapped. . Furthermore, some of the plurality of upper intersection portions 43 in the main absorber 13 overlap with the center (intersection of diagonal lines) of the lower non-squeezed region 52 of the sub-absorber 14. In particular, in a range where the pattern of the upper compression line 41 of the main absorber 13 and the pattern of the lower compression line 51 of the sub-absorber 14 overlap, the upper intersection portion 43 is located within the range of all the lower non-compression regions 52. Exists. For this reason, in this embodiment, it turns out that the upper side compression line 41 has overlapped on the position corresponding to the diagonal line of the lower side non-compression area | region 52 which forms a square. Furthermore, in the present embodiment, it can be seen that the lower compression line 51 overlaps within the range of the upper non-compression region 42.

  Further, as shown in FIG. 36, the length D1 of the diagonal line along the longitudinal direction of the upper non-squeezed area 42 (normal oblong) is equal to the length L of the lower non-squeezed area 52 (square) in the longitudinal direction. Almost equal (D1 = L). The length D2 of the diagonal line along the width direction of the upper non-squeezed area 42 (orthogonal rectangle) is substantially equal to the width B of the lower non-squeezed area 52 (square) (D2 = B). In this specification, “substantially” means that an error of ± 5% is allowed. By satisfying these conditions, the upper compression line 41 overlaps a position corresponding to a diagonal line of the lower non-compression region 52 having a square shape.

  Thus, in the present embodiment, the lower compression line 51 overlaps within the range of the upper non-compression region 42, the upper compression line 41 and the upper intersection 43 overlap within the range of the lower non-compression region 52, and The upper intersection 43 and the lower intersection 53 overlap. Therefore, the body fluid diffused along the upper compression line 41 of the main absorber 13 falls into the sub-absorber 14 and is absorbed by the lower non-compression region 52. In addition, the bodily fluid retained in the upper intersection 43 of the main absorber 13 falls into the sub-absorber 14 and diffuses along the lower compression line 51 through the lower intersection 53. Further, the body fluid diffused along the lower compression line 51 of the sub-absorber 14 is absorbed by the upper non-compression region 42 of the main absorber 13. Further, the lower compressed line 51 can also diffuse body fluid in a diagonal direction of the lattice pattern of the upper compressed line 41. Thus, by forming such a pattern, it becomes possible to quickly guide the body fluid to the non-squeezed regions 42 and 52, which were conventionally considered to have a slow absorption time.

  Here, specific numerical values regarding the components of the absorbent article will be described. For example, the thickness of each of the absorbers 13 and 14, that is, the thickness of the non-squeezed regions 42 and 52 is preferably 5 mm to 20 mm, and particularly preferably 8 mm to 15 mm. Further, the thickness of each of the absorbers 13 and 14 at the portion where the squeezing lines 41 and 51 are formed is preferably 1 mm to 10 mm, and particularly preferably 2 mm to 5 mm. However, as a matter of course, the thickness of the portion where the compression lines 41 and 51 are formed is smaller than the thickness of the non-compression regions 42 and 52. For example, the thickness of the portion where the compression lines 41 and 51 are formed is 3% to 50%, particularly preferably 5% to 20% with respect to the thickness of the non-compression regions 42 and 52.

  Further, the width of each of the pressing lines 41 and 51 is preferably 1 mm to 5 mm, and particularly preferably 2 mm to 4 mm. The length D1 of the diagonal line in the longitudinal direction of the upper non-squeezed region 42 shown in FIG. 36 is preferably 10 mm to 50 mm, particularly preferably 20 mm to 40 mm, or 30 mm. A preferable numerical range of the length D2 of the diagonal line in the width direction of the upper non-squeezed 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 rhombus (regular rhombus), but may be another rhombic shape. In addition, the length L of the lower non-squeezed region 52 shown in FIG. 36 is preferably 10 mm to 50 mm, particularly preferably 20 mm to 40 mm, or 30 mm. The preferred numerical range of the width B of the lower non-squeezed 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, it is a preferred embodiment that the length D1 and the length L are substantially equal and the length D2 and the width B are substantially equal, but the present invention is not limited to this.

  Also, the pressing lines 41, 51 formed on each of the absorbers 13, 14 have a wide range in the longitudinal direction so that the body fluid discharged in the vicinity of the crotch can be widely diffused to the front body and the back body. Is preferably formed. Specifically, the length in the longitudinal direction of the region where the squeezing lines 41 and 51 are formed is preferably 60% or more with respect to the length in the longitudinal direction of each of the absorbers 13 and 14, and 60% or more. Particularly preferred is 100%, 70% to 100%, or 80% to 100%. The pressing lines 41 and 51 formed on the absorbers 13 and 14 have a wide range in the width direction so that the body fluid discharged in the vicinity of the center in the width direction can be widely diffused to the outside in the width direction. Is preferably formed. Specifically, the maximum width in the width direction of the region where the upper compression 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 absorber 13, and is preferably 60% or more. Particularly preferred is 100%, 70% to 100%, or 80% to 100%. Further, the maximum width in the width direction of the region where the lower side compression line 51 is formed is preferably 60% or more with respect to the width in the width direction of the sub-absorbent 14, and 60% to 100%, 70% to 70%. Particularly preferred is 100%, or 80% to 100%.

  In addition, the drawing shows an example in which the compression lines 41 and 51 are formed by depressing both the absorbent materials 13a and 14a and the core wrap sheets 13b and 14b that constitute the absorbers 13 and 14, respectively. However, the squeezing lines 41 and 51 only need to be formed by compressing and depressing at least the absorbent materials 13a and 14a. That is, after the absorbent materials 13a and 14a are compressed to form the compression lines 41 and 51, the core wrap sheets 13b and 14b may be joined so as to cover the absorbent materials 34 and 44. In this sense, it is sufficient that the compression lines 41 and 51 are formed on the absorbent materials 13a and 14a constituting the absorbers 13 and 14, respectively.

[12. Ninth embodiment]
Subsequently, an absorbent article according to a ninth embodiment of the present invention will be described with reference to FIGS. 38 and 39. Regarding the ninth embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will be focused on the configuration that is different from the above-described embodiment.

  FIGS. 38A and 38B show the main absorber 13 and the sub absorber 14 separately, and FIGS. 38C and 38D show cross-sectional shapes along XXXVIII-XXXVIII. . FIG. 39 shows a pattern of a compression line 41 formed on the main absorber 13 and a pattern of a compression line 51 formed on the sub-absorber 14 in a state where the main absorber 13 and the sub-absorber 14 are overlapped. Is enlarged. 38 and 39 conceptually show only the main absorber 13 and the sub absorber 14 extracted.

  The ninth embodiment differs from the eighth embodiment in the pattern of the compression lines 41 and 51 formed on the absorbers 13 and 14. As shown in FIG. 38 and FIG. 39, the upper compression line 41 is formed in a square lattice pattern on the main absorber 13, and the lower compression line 51 is formed on the sub-absorber 14 in a regular rhombic shape. It is formed in a lattice pattern. The regular rhombic lattice pattern and the square lattice pattern here 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 superimposed, a square lattice pattern formed on the main absorber 13 and a regular rhombus formed on the sub-absorber 14 The relative positional relationship of the lattice pattern is different from that of the eighth embodiment.

  As can be seen from the figures, in the ninth embodiment, the area of the upper non-squeezed area 42 is larger than the area of the lower non-squeezed area 52. For this reason, when the main absorber 13 and the sub-absorber 14 are overlapped, the lower non-squeezed region 52 (regular oblong shape) falls within the range of the upper non-squeezed region 42 (square).

  Further, in the ninth embodiment, four lower pressing lines 41 defining a certain upper non-squeezed area 42 (square) are respectively attached to four lower pressing lines 41 defining a certain lower non-squeezed area 52 (rectangular rectangle). The side intersections 53 overlap. For this reason, as shown in FIG. 39, it can be seen that the lower non-squeezed area 52 (square) fits perfectly in the range of the upper non-squeezed area 42 (square). That is, the center (intersection of diagonal lines) of the upper non-squeezed area 42 (square) coincides with the center (intersection of diagonal lines) of the lower non-squeezed area 52 (rectangular rectangle). Further, as shown in FIG. 38, the length L in the longitudinal direction of the upper non-squeezed region 42 (square) is equal to the length D1 of the diagonal line along the longitudinal direction of the lower non-squeezed region 52 (square). 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 that define a certain lower non-squeezed area 52 (orthogonal square) are respectively formed on the four sides of the upper squeezed line 41 that defines the upper non-squeezed area 42 (square). The parts 53 overlap.

  Further, as shown in FIG. 39, the upper intersections 43 overlap the centers (diagonal intersections) of the lower non-squeezed regions 52 (orthogonal rectangles). From another point of view, in the plurality of lower non-squeezed regions 52 (orthogonal rectangles), there are those in which the upper intersection 43 overlaps and those in which the upper intersection 43 does not overlap. In the example shown in FIG. 39, among the plurality of rows of the lower non-squeezed region 52, the rows of the upper intersection 43 and the rows of the upper intersection 43 that do not overlap are alternately arranged every other row. You can see that there is. Similarly, it can be seen that, of the plurality of rows of the lower non-squeezed area 52, every other row, rows where the upper intersection 43 overlaps and rows where the upper intersection 43 does not overlap are alternately arranged.

  As described above, by forming the pattern of the upper compression line 41 (square lattice shape) and the pattern of the lower compression line 51 (regular rhombic lattice shape), the compression lines are not densely formed in one absorber. Even so, the body fluid can be effectively diffused into the non-squeezed region, and the body fluid can be absorbed over a wide range of the entire two-layer absorber. That is, the body fluid diffused along the upper compression line 41 of the main absorbent body 13 is absorbed by the lower non-compressed region 52 of the sub absorbent body 14. For this reason, the body fluid diffused along the upper compression line 41 of the main absorbent body 13 does not easily reach the end portion, and it is possible to effectively prevent the body fluid from leaking to the outside. Further, since the body fluid can be absorbed in a wide range of the two-layer absorbers 13 and 14, the absorption amount of the body fluid is improved and the wearer is less likely to feel discomfort even when worn for a long time. . At the intersections 43 and 53 formed on the absorbers 13 and 14, the squeezing lines 41 and 51 intersect, so that bodily fluids are easily retained. Therefore, by overlapping the upper intersection 43 of the main absorber 13 with the lower non-squeezed region 52 of the sub-absorber 14, the body fluid retained in the upper intersection 43 can be effectively penetrated into the lower non-squeezed region 52. Becomes possible.

  Also, as in the ninth embodiment, by setting the columns and rows of the lower non-squeezed region 52 where the upper intersection 43 overlaps every other column and every other row, the bodily fluid that has permeated the main absorbent body 13 is It can be spread to more distant regions. Therefore, the body fluid that has permeated the main absorber 13 can be diffused and permeated over a wide range of the sub absorber 14.

  Further, the squeezing line has a function of flowing the liquid as a groove and a function of diffusing the liquid along the squeezed portion using a capillary phenomenon in a non-squeezed region around the squeezed portion. Even when used in a form that does not function as a groove, liquid transfer occurs from the squeezing line of one absorber to the squeezing line or non-squeezed area of the other absorber. The reason is as follows. That is, the squeezing line is obtained by crushing the absorbent material constituting the absorber by pressure. For this reason, when the absorber absorbs the liquid at the portion where the compression line is formed, the thickness changes. That is, when the pulp or SAP in the squeezed line absorbs liquid, the interval between the pulp is loosened over time and the SAP swells, so that the squeezed line gradually becomes shallow, and finally the swelled non-squeezed area and The thickness is almost the same. Thus, even if the compressed line has a depth before absorption, the depth gradually decreases as the liquid absorption proceeds. For this reason, it is easy to transfer the liquid from the compression line of one absorber to a compression line or a non-compression region provided on the other absorber that overlaps with the compression line. That is, since the compression line is a groove in the initial state, the liquid flows into the compression line preferentially. And, since the compression line swells as the liquid absorption advances in the portion where the compression line is formed, as described above, the liquid flows to the compression line or the non-compression region provided on the other absorbent body overlapping the swollen compression 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. In contrast, the pattern of the eighth embodiment can be said to have a higher body fluid absorption rate than the pattern of the ninth embodiment. For this reason, when forming a squeezing line in each of two layers of absorbers, 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 it suitably in consideration.

  In addition, the width of each compressed line 41, 51, the length D1 of the diagonal in the longitudinal direction of the upper non-squeezed area 42, the length D2 of the diagonal in the width direction, or the length L of the lower non-squeezed area 52 in the longitudinal direction, The value of the width B is preferably in the same range as in the above-described eighth embodiment.

[13. Tenth embodiment]
Subsequently, a tenth embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the tenth embodiment, the description of the same configuration as that of the above-described embodiment will be omitted, and the description will focus on the configuration that is 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 shown in FIG. 40, the absorbent article 100 according to the present invention has a cylindrical three-dimensional shape having a space 4 therein. In the present embodiment, the back surface sides of both ends of one planar rectangular absorbent main body 10 are formed into a cylindrical shape having a space 4 extending along the depth direction (D) with the back sides facing each other. The absorbent main body 10 having a three-dimensional shape includes a top surface portion 1 having a surface in contact with a wearer's crotch, and left and right side surface portions 2 extending from both left and right sides of the top surface portion 1 toward the skin non-facing surface side. 3 (left side surface 2 and right side surface 3) and a space 4 formed between the left and right side surfaces 2 and 3. The space 4 penetrates along the depth direction (D) from the abdominal end of the wearer to the dorsal end. Furthermore, a liquid-impermeable leakproof sheet 20 is attached to the lower end 5 of the left and right side surfaces 2 and 3 of the absorbent main body 10. The leakage prevention sheet 20 is joined across the left and right side parts 2 and 3 and also has a function of connecting the side parts 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.

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

  As shown in FIGS. 40 and 41, the absorber 13 has a plurality of squeezing lines 41 formed at least on the left and right side surfaces 2 and 3. The compression line 41 is a linear concave portion formed by partially compressing the absorber 13. Preferably, the plurality of squeezing lines are a plurality of parallel squeezing lines or a plurality of squeezing lines defining a closed area. Also, it is particularly preferred that the plurality of squeezed lines are a plurality of parallel squeezed lines defining a closed area. In the embodiments shown in FIGS. 40 and 41, the pressing lines are formed in a lattice shape. The lattice shape means a state in which a group of a plurality of compressed lines extending in a certain direction intersects with a group of a plurality of compressed lines extending in a different direction. The pressing lines 41 may be formed in a rhombic lattice pattern as shown in FIG. 41 and the like, or may be formed in a square lattice pattern. That is, when the absorbent body 13 is spread out in a plane as shown in FIG. ) Extending along a direction inclined at an angle of 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, and particularly 30 to 45 degrees, or 35 to 45 degrees. Is preferred.

  In addition, the compression line 41 can be basically formed by compressing the absorber 13 from the skin-facing surface side. However, the squeezing line 41 may be formed by compressing the absorber 13 from the non-skin-facing surface side, or compressing the absorber 13 from both sides of the skin-facing surface and the non-skin-facing surface. May be formed. As described above, since the compression line 41 is a portion where the absorber 13 is compressed, the strength of the absorber 13 is improved at the portion where the compression line 41 is formed (the left and right side portions 2 and 3).

  As shown in FIG. 40 and FIG. 41, by forming the grid-shaped squeezing lines 41 on the left and right side portions 2 and 3 of the absorber 13, the bodily fluid that has contacted or penetrated the left and right side portions 2 and 3 It diffuses along the pressing line 41. As a result, the body fluid can be rapidly absorbed over a wide range of the side portions 2 and 3, and the effect of preventing urine leakage can be enhanced. In addition, by forming a lattice-shaped squeezing line 41 on the absorber 13 at a portion corresponding to the left and right side portions 2 and 3 of the absorbent article 100, the stress of the left and right side portions 2 and 3 is increased. Therefore, even when the absorbent biological product 100 is sandwiched between the legs of the wearer, 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. Can be. This makes it easier for the absorbent article 100 to adhere to the wearer's crotch and inner thigh.

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

  41, 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, and the lower end thereof is bound by the leak-proof sheet 20. Thereby, the absorbent article 100 including the absorbent main body 10 and the leak-proof sheet 20 has a tubular three-dimensional shape as shown in FIG. Further, as shown in FIG. 42, a leak-proof sheet 20 is attached to the lower end 5 of the absorbent main body 10 across the left side surface 2 and the right side surface 3. For this reason, it can be said that the leakage prevention sheet 20 has a function of connecting the left side part 2 and the right side part 3 of the absorbent main body 10.

  Further, as shown in FIGS. 40 to 42, the lattice-shaped squeezing line 41 is formed in at least the liquid-absorbing part 6 of the left and right side parts 2 and 3 to which the leak-proof sheet 20 is not attached. Is preferred. By providing the grid-shaped compression lines 41 in the liquid absorbing section 6, it is possible to prevent the compression lines 41 from being hidden behind the leak-proof sheet 20. As a result, the bodily fluid that has adhered to or penetrated the liquid absorbing portion 6 diffuses along the squeezing line 41 into the range. In addition, it is preferable that the compression line 41 be formed continuously not only from the liquid absorbing portion 6 but also from the liquid absorbing portion 6 to the lower end portion 5 to which the leak-proof sheet 20 is attached. That is, it is preferable that the lattice-shaped squeezing line 41 extends continuously from the liquid absorbing portion 6 to the lower end portion 5 beyond the edge of the leak-proof sheet 20. As described above, since the compression line 41 is provided so as to connect from the liquid absorbing portion 6 to the lower end portion 5, the body fluid absorbed by the liquid absorbing portion 6 can be passed through the compression line 41 to the back of the leakproof sheet 20. It can be quickly guided to the hidden lower end portion 5. Since the lower end portion 5 is hidden behind the leak-proof sheet 20, the bodily fluid hardly permeates into the lower end portion 5, but the squeezing line 41 functions as a flow path for carrying the bodily fluid to the lower end portion 5. Thereby, the body fluid can be diffused over a wider range.

  Further, as shown in FIG. 40, in the present embodiment, the left and right side portions 2 and 3 are formed with a compression line forming region 6a in which a lattice-like compression line 41 is formed and a compression line 41. It is divided into a compression line non-forming region 6b which is a region not formed. In the present embodiment, the compression line forming region 6a is provided on the lower end sides of the left and right side portions 2 and 3, and the compression line non-forming region 6b is provided between the top surface portion 1 (the mountain fold 8) and the compression line forming region 6a. It is provided in. Since the absorber 13 is partially compressed, the squeezing line forming region 6a has a slightly soft touch. On the other hand, in the non-pressed line forming region 6b, the pressed line 41 does not exist and the touch is relatively soft. Therefore, by providing the compression line 41 between the top surface portion 1 and the compression line forming region 6a, it is possible to improve the feel of the absorbent article 100 that comes into contact with the vicinity of the hip joint of the wearer. Thereby, the wearing feeling of the absorbent article 100 is improved. Further, even if the area where the compression line 41 is formed is limited to the lower end sides of the left and right side parts 2 and 3, the bodily fluid that has permeated the absorber 41 flows downward according to gravity, and eventually the compression line formation area 6 a To reach. Then, the bodily fluid that has reached the compression line forming region 6a is widely diffused along the compression line 41. Thus, in the present invention, the compression line non-forming region 6b is provided above the left and right side portions 2 and 3, and the compression line forming region 6a is provided below it. Thereby, while maintaining the diffusibility of the bodily fluids, for example, the wearer is less irritated to the skin as compared with the case where the compression lines are formed on the entire left and right side portions 2 and 3, and the touch can be improved. .

  Further, the length in the height direction (H) of the compression line non-forming region 6b is preferably 20% or more of the entire 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 non-pressed line forming region 6b is preferably 20 to 70%, and more preferably 30 to 50%. As described above, by securing the range of the compression line non-forming region 6b to a certain value or more, it is possible to soften the touch of the part that comes into contact with the vicinity of the hip joint of the wearer.

  FIG. 43 shows an example in which the absorbent article 100 is sandwiched between the wearer's crotch. As shown in FIG. 43, of the absorbent main body 10, the top surface portion 1 that forms a flat surface closely adheres to the wearer's crotch, and the side surface portions 2 and 3 located on the left and right sides of the absorbent body 10 are attached to the inner thigh of the wearer. In close contact. Further, since the space 4 is held between the left and right side portions 2, 3, the absorbent main body 10 has a high cushioning property as a whole, and the close contact with the crotch and the inner thigh is maintained. Thereby, a gap is less likely to be formed between the absorbent main body 10 and the wearer's skin, and even when worn on a wearer in a lateral or semi-lateral position, the top surface 1 side or Urine leakage from the side portions 2 and 3 can be effectively prevented. 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 prevent the underwear, the sheets, or the disposable diapers that are repeatedly mounted from being stained. When the absorbent article 100 is replaced, the replacement work can be easily completed without soiling the hands by pulling out the leakage prevention sheet 20 while holding the sheet.

  FIGS. 44A to 44E show an example of a manufacturing process of the absorbent article 100 according to the tenth embodiment. FIG. 44 shows a cross-sectional view taken along the line XLIV-XLIV along with the drawings. The absorbent article 100 can be manufactured by the procedure shown in FIGS. 44 (a) to 44 (e). That is, first, the rectangular outer sheet 11 is prepared, and the rectangular absorber 13 in which the through-hole 7 and the lattice-shaped squeezing line 41 are formed is placed on the non-skin facing side of the outer sheet 11 (FIG. 44 (a)). At this time, the through-hole 7 is not formed in the outer sheet 11. Next, the inner sheet 12 is placed on the non-skin facing side of the absorber 13 (FIG. 44B). At this time, the outer sheet 11 and the inner sheet 12 are joined around the absorber 13. The absorber 13 may be joined to both or any one of the outer sheet 11 and the inner sheet 12. Thereby, the absorbent main body 10 is obtained. At this stage, the through holes 7 are not formed in the outer sheet 11. Next, the absorbent main body 10 is folded in half toward the inner sheet 12 along the through holes 7 formed in the absorber 13 (FIG. 44 (c)). That is, the sheet is folded in two such that the outer sheet 11 is on the outside and the inner sheet 12 is on the inside. At this time, the through-hole 7 of the absorber 13 is located at the vertex of the fold. Thereafter, the apex portion of the absorber 13 where the through-hole 7 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. 44 (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 same position as the through-hole 7 of the absorber 13 is cut off, so that the outer sheet 11 and the inner sheet 12 are almost simultaneously. Through holes 7 can be formed. Thereafter, the leak-proof sheet 20 is joined to a position corresponding to the lower end of the absorbent main body 10 (FIG. 44 (e)). At this time, the leakage prevention sheet 20 partially covers the region where the compression lines 41 are formed (the compression line formation region 6a). In addition, a step of forming the mountain fold 8 may be added to an appropriate position of the absorbent main body 10 constituting the absorbent article 100. Further, a step of bonding the end on the opposite side to the apex of the two-fold (that is, the end on the side where the leak-proof sheet 20 is disposed) with a hot melt adhesive or the like may be added.

  By following the above manufacturing process, the absorbent article 100 in which the through holes 7 are formed can be manufactured efficiently. Further, as shown in FIG. 44 (c), after the through-hole 7 is formed in the absorber 13, the entirety of the absorbent main body 10 is folded in two along the through-hole 7, so that the The creases on the top surface 1 can be minimized. That is, as described above, it is preferable that the top surface portion 1 be a flat surface and no folds remain. However, by forming the folds that occur during manufacturing along the through holes 7, the folds formed on the top surface portion 1 can be minimized. Limit. Thus, it is possible to make the fold hardly remain on the top surface portion 1 when worn.

[14. Eleventh embodiment]
Subsequently, an eleventh embodiment of the absorbent article 100 according to the present invention will be described with reference to FIGS. Regarding the eleventh embodiment, the description of the same configuration as that of the above-described tenth embodiment will be omitted, and the description will focus on the configuration different from the tenth embodiment.

  FIG. 45 is an exploded perspective view of the absorbent article 100 according to the second embodiment, and FIG. 46 is 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 has two sub-absorbers 14 in addition to the components described in the tenth embodiment. .

  As shown in FIG. 46, in the present embodiment, the sub-absorbers 14 are arranged on the left and right side surfaces 2 and 3 of the absorbent main body 10 one by one. In particular, the two sub-absorbers 14 are arranged on the non-skin-facing surface side of the main absorber 13 constituting the top surface 1 and the left and right side surfaces 2, that is, between the main absorber 13 and the inner sheet 12. I have. Note that each sub-absorber 14 may be composed of an absorbent material 14a and a core wrap sheet 14b, similarly to the main absorber 13. By overlapping the main absorber 13 and the sub-absorber 14 on the left and right side portions 2 and 3 as in the present embodiment, the amount of body fluid absorbed by the side portions 2 and 3 increases. In particular, the body fluid introduced into the space 4 through the through hole 7 of the top surface portion 1 can be absorbed in a large amount by the sub-absorbers 14 arranged on the side surfaces 2 and 3. For this reason, it can be said that the present embodiment is directed to a man who inserts the penis into the through hole 7 of the top surface 1 and uses the penis. Note that, as shown in FIG. 46, it is preferable that the sub-absorber 14 is arranged at least on the lower end 5 side of the left and right side portions 2 and 3 so as to overlap the main absorber 13. However, the sub absorber 14 may be disposed over the main absorber 13 over the entire left and right side portions 2 and 3. Although not shown, the sub-absorber 14 may be disposed on the skin-facing surface side of the main absorber 13, that is, between the main absorber 13 and the outer sheet 11.

  As shown in FIGS. 45 and 46, in the eleventh embodiment, compressed lines 41, 51 in which the absorbers 13, 14 are recessed in the thickness direction are respectively provided on the main absorber 13 and the sub absorber 14. Are formed. That is, a plurality of compression lines 41 and 51 are formed on each of the main absorber 13 and the sub absorber 14. The compression lines 41 and 51 are formed by partially pressing and compressing the compression lines 41 and 51 from both sides or any one of the skin-facing surface side and the non-skin-facing surface side. Therefore, the density of the absorbent material 13a, 14a in each of the absorbers 13, 14 increases in the portion where the compression lines 41, 51 are formed. The compression lines 41 formed on the main absorber 13 and the compression lines 51 formed on the sub-absorber 14 form a pattern that at least partially intersects each other when viewed from the plane. Hereinafter, the pattern of the compression line 41 formed on the main absorber 13 and the pattern of the compression line 51 formed on the sub-absorber 14 will be described in detail.

  FIG. 47 shows a state where the patterns of the compression lines 41 and 51 formed on the main absorber 13 and the sub absorber 14 are overlapped. As shown in FIGS. 45 and 47, the squeezing lines 41 are formed in the main absorber 13 in a pattern of a rhombic lattice. Here, the “rhombic lattice pattern” is a pattern in which a plurality of compression lines extending in a direction inclined with respect to the longitudinal direction and the width direction intersect to define a rhombic (rhombic) non-compressed 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 Preferably it is 35 degrees to 45 degrees. In particular, in the present embodiment, the pattern of the compression lines 41 in the main absorber 13 is a regular pattern (a regular rhombus) in which all the non-compression regions 42 surrounded on all sides by the compression lines 41 have a regular rhombus (regular rhombus) shape. (A square lattice pattern). As described above, the main absorbent body 13 is formed with a plurality of compression lines 41, a non-compression region 42 surrounded by the compression lines 41, and an intersection 43 where the compression lines 41 intersect. can do. Hereinafter, for convenience, the compression line 41 of the main absorbent body 13 is referred to as “upper compression line 41”, the non-compression region 42 is referred to as “upper non-compression region 42”, and the intersection 43 is referred to as “upper intersection portion 43”.

  On the other hand, the compressed lines 51 are formed in the sub-absorber 14 in a rectangular lattice pattern. The “square lattice pattern” here means that a plurality of squeezing lines extending parallel to the longitudinal direction and a plurality of squeezing lines extending parallel to the width direction intersect to define a square non-squeezed region. Refers to a pattern. In particular, in the present embodiment, the pattern of the compression lines 51 in the sub-absorber 14 is a regular pattern (a square lattice pattern) in which all the non-compression regions 52 surrounded on all sides by the compression lines 51 are square. Has become. As described above, also in the sub-absorber 14, a plurality of compressed lines 51, a non-compressed area 52 surrounded by the compressed lines 51, and an intersection 53 where the compressed lines 51 intersect are formed. can do. Hereinafter, for convenience, the compression line 51 in the sub-absorber 14 is referred to as a “lower compression line 51”, the non-compression region 52 is referred to as a “lower non-compression region 52”, and the intersection 53 is referred to as a “lower intersection 53”. .

  In the present embodiment, the upper compression line 41 is formed by compressing and denting the main absorbent body 13 from the skin-facing surface side. Similarly, the lower compression line 51 is formed by compressing and denting the sub-absorbent body 14 from the skin-facing surface side. For this reason, a gap is formed between the main absorber 13 and the sub-absorber 14 in a state where the lower compression line 51 is formed in the sub-absorber 14 in a state where the lower compression line 51 is formed.

  As can be seen from FIG. 47, in the present embodiment, the area of the lower non-squeezed area 52 is larger than the area of the upper non-squeezed area 42. For this reason, when the main absorber 13 and the sub-absorber 14 are overlapped, the upper non-squeezed area 42 (square) fits within the range of the lower non-squeezed area 52 (square).

  Further, in the present embodiment, four upper intersections that define a certain upper non-squeezed area 42 (a regular oblong rectangle) are respectively provided on four lower squeezed lines 51 that define a certain lower non-squeezed area 52 (square). The parts 43 overlap. For this reason, as shown in FIG. 47, it can be seen that the upper non-squeezed area 42 (square rectangle) fits perfectly in the range of the lower non-squeezed area 52 (square). That is, the center (intersection of diagonal lines) of the lower non-squeezed area 52 (square) coincides with the center (intersection of diagonal lines) of the upper non-squeezed area 42 (regular oblong). Further, as shown in FIG. 47, the length L in the longitudinal direction of the lower non-squeezed region 52 (square) is equal to the length D1 of the diagonal along the longitudinal direction of the upper non-squeezed region 42 (square). Almost equal (L = D1). 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 line 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 area 42 (a regular oblong) are respectively formed on four lower squeezed lines 51 that define a lower non-squeezed area 52 (square). The parts 43 overlap. In this specification, “substantially” means that an error of ± 5% is allowed.

  As described above, by forming the pattern of the upper compression line 41 (regular oblong lattice) and the pattern of the lower compression line 51 (square lattice), the compression line is not densely formed in one absorber. Even so, the body fluid can be effectively diffused into the non-squeezed region, and the body fluid can be absorbed over a wide range of the entire two-layer absorber. That is, the body fluid diffused along the upper compression line 41 of the main absorbent body 13 is absorbed by the lower non-compressed region 52 of the sub absorbent body 14. For this reason, the body fluid diffused along the upper compression line 41 of the main absorbent body 13 does not easily reach the end portion, and it is possible to effectively prevent the body fluid from leaking to the outside. Further, since the body fluid can be absorbed in a wide range of the two-layer absorbers 13 and 14, the absorption amount of the body fluid is improved and the wearer is less likely to feel discomfort even when worn for a long time. . At the intersections 43 and 53 formed in the absorbers 13 and 14, the squeezing lines 41 and 51 intersect, so that bodily fluids are easily retained. Therefore, the upper intersection 43 of the main absorber 13 is overlapped with the lower compression line 51 of the sub-absorber 14 so that the bodily fluid retained in the upper intersection 43 is introduced into the lower compression line 51 and the sub-absorber 14 Can be effectively penetrated.

  FIG. 48 shows a modification of the pattern of the compression lines 41 formed on the main absorber 13 and the pattern of the compression lines 51 formed on the sub-absorber 14. In the modification shown in FIG. 48, the upper intersection 43 of the main absorber 13 and the lower intersection 53 of the sub-absorber 14 overlap each other when the absorbers 13 and 14 are overlapped. Furthermore, some of the plurality of upper intersection portions 43 in the main absorber 13 overlap with the center (intersection of diagonal lines) of the lower non-squeezed region 52 of the sub-absorber 14. In particular, in a range where the pattern of the upper compression line 41 of the main absorber 13 and the pattern of the lower compression line 51 of the sub-absorber 14 overlap, the upper intersection portion 43 is located within the range of all the lower non-compression regions 52. Exists. Further, in the present embodiment, it can be seen that the lower compression line 51 overlaps within the range of the upper non-compression region 42.

  As described above, in the modification illustrated in FIG. 48, the lower compression line 51 overlaps with the range of the upper non-compression region 42, and the upper compression line 41 and the upper intersection point 43 within the range of the lower non-compression region 52. The upper intersection 43 and the lower intersection 53 overlap each other. Therefore, the body fluid diffused along the upper compression line 41 of the main absorber 13 falls into the sub-absorber 14 and is absorbed by the lower non-compression region 52. In addition, the bodily fluid retained in the upper intersection 43 of the main absorber 13 falls into the sub-absorber 14 and diffuses along the lower compression line 51 through the lower intersection 53. Further, the body fluid diffused along the lower compression line 51 of the sub-absorber 14 is absorbed by the upper non-compression region 42 of the main absorber 13. Further, the lower compressed line 51 can also diffuse body fluid in a diagonal direction of the lattice pattern of the upper compressed line 41. Thus, by forming such a pattern, it becomes possible to quickly guide the body fluid to the non-squeezed regions 42 and 52, which were conventionally considered to have a slow absorption time.

  Thus, it can be said that the pattern shown in FIG. 48 has a higher body fluid absorption rate than the pattern shown in FIG. On the other hand, it can be said that the pattern of FIG. 47 has a wider range of body fluid diffusion than the pattern of FIG. For this reason, when forming a compression line in each of two layers of absorbers, which pattern of FIG. 47 or FIG. 48 should be adopted may be appropriately determined in consideration of the performance required of the absorbent article. .
