200932199 九、發明說明 【發明所屬之技術領域】 本發明是有關一種吸收性物品。特別是有關一種防漏 性優的吸收性物品。 【先前技術】 自以往，據知供吸收經血等之排泄物的吸收性物品， 例如有生理用衛生棉、衛生護墊、尿片等。該等之吸收性 物品，一般具有：配置在肌虜抵接面側的透液性的表面薄 片；和配置在穿戴側的不透液性的裏面薄片；和配置在表 面薄片與裏面薄片之間的保液性的吸收體，例如以黏貼在 內褲之內面的狀態使用。 可是，由於此種吸收性物品一旦經血等之排泄物漏出 的話，即有污染內褲等衣物之虞，因此通常要求確實地防 止經血等之排泄物漏出。因此必須減少吸收體與排泄部的 間隙，利用吸收體確實地吸收經血等之排泄物。 但是例如像是生理用衛生棉以黏貼在內褲之內面的狀 態使用的吸收性物品，一旦在穿戴的狀態下移動身體的話 ，易在內褲與排泄部之間產生相對性的偏位，該偏位具有 造成排泄物漏出之原因的情形。 又，例如，生理用衛生棉，通常以抵接在穿戴者之排 泄部的狀態穿戴使用。總之就是，由於生理用衛生棉’係 以夾在穿戴者的大腿部之間的狀態使用，因此常常由穿戴 者的大腿部受到橫向的壓縮力。藉此，吸收體會壓縮變形 -5 - 200932199 ，因變形狀態而在穿戴者的排泄部與生理用衛生棉之間形 成間隙，具有造成排泄物漏出之原因的情形。 【發明內容】 [發明欲解決之課題] 對此，針對於生理用衛生棉之長方向延伸的中心線， 設置大致線對稱的一對溝，該溝分別於長方向的中央區域 ，形成朝寬度方向之內側凹狀地彎曲，並且設置防漏壁的 生理用衛生棉，例如揭示於日本特開2003-243 84號公報。 但是，由於揭示於日本特開2003 -24384號公報的生理 用衛生棉，係在長方向的中央區域，僅溝部之一處凹狀地 形成在寬度方向的內側，因此例如在穿戴時從穿戴者的大 腿部施加寬度方向的力之情形下，力會集中在凹狀之底部 的一處。因此，防漏壁只會在長方向的一部分直立，例如 流出多量的體液之際，具有無法利用防漏壁抑制的情形。 又，在體液等從防漏壁漏出到其他區域的情形下，會有體 液直接接觸到肌膚的情形，具有賦予穿戴者不快之虞。 本發明是有鑑於如上的課題所完成的發明，目的在於 提供一種確保吸收性物品已穩定的變形形態，藉此提升對 肌膚的抵接性，能防止體液等洩漏的吸收性物品。 [用以解決課題之手段] 本發明人等爲了達成上述目的，發現藉由在吸收性物 品的兩側設置防漏壁，並且在長方向的中央區域，設置向 -6 -

Description of the Invention [Technical Field to Which the Invention Is Alonged] The present invention relates to an absorbent article. In particular, it relates to an absorbent article that is excellent in leakproofness. [Prior Art] Conventionally, an absorbent article for absorbing excrement such as menstrual blood has been known, for example, a sanitary napkin, a sanitary pad, a diaper, or the like. The absorbent article generally has: a liquid permeable surface sheet disposed on the side of the tendon abutting surface; and a liquid-impermeable back sheet disposed on the wear side; and disposed between the surface sheet and the inner sheet The liquid-repellent absorbent body is used, for example, in a state of being adhered to the inner surface of the undergarment. However, since such an absorbent article leaks out excrement such as menstrual blood, that is, if the clothes such as underwear are contaminated, it is usually required to reliably prevent excretion of menstrual blood or the like from leaking out. Therefore, it is necessary to reduce the gap between the absorbent body and the excretory portion, and to reliably absorb the excretion of menstrual blood or the like by the absorbent body. However, for example, an absorbent article which is used in a state in which the sanitary napkin is adhered to the inner surface of the undergarment, and if the body is moved while being worn, a relative offset between the panty and the excretion portion is easily generated. The position has a cause of leakage of excrement. Further, for example, the sanitary napkin is usually worn in a state of abutting against the excretion portion of the wearer. In short, since the sanitary napkin is used in a state of being sandwiched between the wearer's thighs, it is often subjected to a lateral compressive force by the wearer's thigh. As a result, the absorbent body is compressed and deformed -5 - 200932199, and a gap is formed between the wearer's excretion portion and the sanitary napkin due to the deformed state, which may cause leakage of excrement. [Problem to be Solved by the Invention] In this regard, a pair of grooves having a substantially line symmetry is provided for a center line extending in the longitudinal direction of the sanitary napkin, and the grooves are formed in the central portion in the longitudinal direction to form a width. A sanitary napkin in which the inner side of the direction is concavely curved and is provided with a leakage preventing wall is disclosed, for example, in Japanese Laid-Open Patent Publication No. 2003-24384. However, the sanitary napkin of Japanese Laid-Open Patent Publication No. 2003-24384 is a central portion in the longitudinal direction, and only one of the grooves is formed concavely on the inner side in the width direction, and thus, for example, when worn, from the wearer. In the case where the thigh is applied with a force in the width direction, the force is concentrated at one of the bottoms of the concave shape. Therefore, the leakage preventing wall is only erected in a part of the long direction, for example, when a large amount of body fluid is discharged, there is a case where the leakage preventing wall cannot be suppressed. Further, when a body fluid or the like leaks from the leakage preventing wall to another region, the body fluid directly contacts the skin, and the wearer is unhappy. The present invention has been made in view of the above-described problems, and it is an object of the invention to provide an absorbent article which is capable of preventing leakage of body fluids and the like by improving a shape in which the absorbent article is stabilized. [Means for Solving the Problem] In order to achieve the above object, the inventors of the present invention have found that a leak-preventing wall is provided on both sides of the absorbent article, and a width direction is provided in the central region in the longitudinal direction to -6 - 200932199.

Further, the embodiment of the present invention is not limited to any of the embodiments described below, and the technical scope of the present invention is not limited thereto. Further, the absorbent article according to the present invention has an object of absorbing light blood, urine, vaginal discharge, and the like excreted by the body, and is worn on the inter-femoral part of the body. However, in the following embodiments, the main purpose is absorption. The physiology of the menstrual blood excreted by the female vaginal orifice is illustrated by the example of sanitary napkin. Further, the side facing the excretory portion of the two surfaces of the absorbent article is the skin abutting surface, and the other side on the opposite side is the non-muscle abutting surface, and it is not limited to whether or not the outer side wears clothes. [1] First embodiment The sanitary napkin 1 according to the first embodiment of the present invention will be described with respect to the overall structure of the absorbent article of the present invention. 200932199 [1·1] The entire sanitary napkin 1 of the absorbent article according to the first embodiment of the present invention is disposed on the side of the wearer's skin contact surface of the wearer as shown in FIG. 1 and FIG. a liquid-permeable surface sheet 2 constituting the surface layer; and a side sheet 6 disposed on both sides of the longitudinal direction (LD) to form a leakage preventing wall; and a non-skin abutting surface side of the wearer to form an inner layer a liquid-impermeable inner sheet 3; and a liquid-repellent absorbent body 4 disposed between the surface sheet 2 and the inner sheet 3 to constitute an absorbent layer; and disposed between the surface sheet 2 and the inner sheet 3, and liquid-permeable The intermediate sheet 5; and the longitudinal groove portion 7 formed by continuously pressing the surface sheet 2, the intermediate sheet 5, and the absorbent body 4. Further, on both sides of the longitudinal direction (LD) of the sanitary napkin 1 , flaps 10R and 10L which are folded back and attached to the undergarment are provided. Bonding portions 9R and 9L for bonding to the undergarment are provided on the non-skin contact surface side of the flaps 10R and 10L. Further, the bonding portions 9R' and 9L' are also disposed on the non-skin contact surface side of the back sheet 3 on which the absorbent body 4 is disposed. The sanitary napkin 1 configured as described above is placed on the crotch portion of the undergarment, and the flaps 100R and 10L are used in a state of being attached to the underpants. Further, the sanitary napkin 1 allows the excretion of menstrual blood or the like discharged from the excretion portion to permeate into the liquid permeation region of the surface sheet 2 and the intermediate sheet 5, and is absorbed by the absorbent body 4. At this time, the leakage preventing wall 61 formed by the side sheet 6 is formed in a state of standing upright in the thickness direction (TD) due to the stress from the thigh portion of the wearer, thereby preventing leakage of excrement. In addition, since the back sheet 3 disposed on the non-skin contact surface side is liquid-impermeable, the excrement does not penetrate the non-skin contact surface side, and is maintained in a state of being absorbed by the absorber 4. -10- 200932199 The surface sheet 2 is disposed on the skin contact surface side so as to come into contact with the excretion portion of the wearer during use. The surface sheet 2 may be liquid permeable on the entire surface or partially liquid permeable. Further, it may be constituted by one sheet member or a plurality of sheet members. In the present embodiment, as the sheet 2, a hydrophilic fiber having a fineness of 2.6 dtex and a fiber length of 51 mm, a hydrophobic fiber having a fineness of 2.2 dtex and a fiber length of 51 mm may be used in an amount of 50%, and the basis weight is 30 g/m2I. Hot air is not woven.中间 The intermediate sheet 5 is such that excrement permeating the surface sheet 2 permeates into the absorbent body 4, and also serves as a buffer for use. In the present embodiment, as the intermediate sheet 5, a hot air having a fineness of 2.6 tex and a hydrophilic fiber having a fiber length of 51 mm and having a basis weight of 30 g/m2 can be used. The absorbent body 4 is provided with an absorbing portion 40 in the central portion (C) of the longitudinal direction (LD) of the sanitary napkin 1. The absorbing portion 40 is a Q region surrounded by the vertical groove portion 7, and is also a region that abuts against the excretion portion of the wearer. In the present embodiment, as the absorbent body 4, a kapok leaf kraft pulp having a basis weight of 400 g/m2 may be used, and a 10% superabsorbent polymer may be wrapped by a wiping paper (not shown). The inner sheet 3 is made of a liquid-impermeable sheet material which can prevent the excretion absorbed by the absorber 4 from leaking to the outside. Further, in the case of using a moisture-permeable material in the liquid-impermeable sheet material, it is preferable to reduce the sultry heat during wear and to reduce the unpleasant feeling during wearing. In the present embodiment, as the inner sheet 3, a polyethylene film having a basis area of -11 - 200932199 and a weight of 27 g/m 2 can be used. [1.2] Bonding portion As shown in Fig. 1, the bonding portion 8' is bonded to the surface sheet 2 and the side sheet 6. Specifically, the bonding portion 8' is such that the surface sheet 2 and the side sheet 6 are bonded together by hot melt adhesive. The bonding unit 8 includes a first bonding portion 81 extending in the longitudinal direction (LD) and a length in the central region (C) in the central region (C) of the longitudinal direction (LD) of the sanitary napkin 1 The front side (F) and the rear side (R) of the both end portions of the direction (LD) are the second bonding portions 82 and 83 extending in the longitudinal direction (LD). Here, the central region (C)' refers to a substantially central portion of the longitudinal direction (LD) of the sanitary napkin 1 and includes a position where it can abut against the excretion portion of the wearer when the sanitary napkin 1 is worn. In the present embodiment, the vicinity of the position where the fins 1〇 are formed is included. The first bonding portion 81 is formed on the outer side in the width direction (WD) of the sanitary napkin 1 from the second bonding portions 82 and 83. Specifically, the first bonding flange portion 81 is formed in the inner edge 81a of the width direction (WD) of the second bonding portions 82 and 83 in the width direction (WD) of the first bonding portion 81, 83a is more lateral. Further, the first bonding portion 81 and the second bonding portions 82 and 83 are connected to the connecting portions 84 and 85. Specifically, the end portion of the second bonding portion 82 and the end portion of the first bonding portion 81 are connected to the connecting portion 84, and the end portion of the first bonding portion 81 and the end portion of the second bonding portion 83 are The connecting portion 85 is connected. The connecting portions 84 and 85 are inclined outward in the longitudinal direction (LD), and the first bonding portion 81 and the second bonding portions 82 and 83 are connected in this state. -12- 200932199 In the above embodiment, once the surface sheet 2 and the side sheet 6 are bonded, a substantially trapezoidal pocket formed by the non-adhering portions of the surface sheet 2 and the side sheet 6 is formed in the central portion (C). Section 62. Further, since the side sheet portion of the pocket portion 62 is in the non-adhering direction of the inner edge side in the width direction (WD), for example, in the case of receiving the force from the thigh portion of the wearer, the inner edge side is erected to the thickness. Direction (TD), which forms a leak-proof wall 61. The length _ ' of the inner edge side of the side sheet 6 of the pocket portion 62 is, for example, 120 mm in length in the longitudinal direction (LD) of the sanitary napkin 1 and is 120 mm. Further, the length of the first bonding portion 81 in the longitudinal direction is, for example, 75 to 60 mm. Further, the bonding width of the first bonding portion 81 in the width direction (WD) is, for example, exemplified as 1.5 to 10 mm. Further, the bonding width of the width direction (WD) of the second bonding portions 82 and 83 is, for example, 2.0 to 15 mm. When the position of the width direction (WD) of the sanitary napkin 1 in which the first bonding portion 81 is formed is the basis of the inner edge of the width direction (WD) of the side sheet 6, the side sheet can be exemplified, for example. The distance between the inner edge of the width direction (WD) of 6 and the inner edge 81a of the first bonding portion 81 is 4.0 to 30 mm. The distance between the inner edge 81a of the first bonding portion 81 and the inner edges 82a and 83a of the second bonding portions 82 and 83 in the width direction is, for example, 3.0 to 25 mm 〇 [1.3] vertical groove portion as shown in Fig. 1 As shown in the figure, the sanitary napkin 1 is provided on both sides in the longitudinal direction (LD) and has a longitudinal groove portion 7 extending in the longitudinal direction (LD). The vertical groove portion 7 is formed by continuously pressing the surface sheet 2, the intermediate sheet 5, and the absorbent body 4 from the skin contact surface side and the non-skin contact surface side, respectively, from -13 to 200932199. Specifically, the high-pressure press section and the low-pressure press section are continuously connected to each other so as to be continuously pressed from the skin contact surface side and the non-skin contact surface side. Thereby, the sanitary napkin 1 has a rigid region formed by the high pressure press portion and the low pressure press portion. The longitudinal groove portion 7 is preferably formed in an integrated manner from the surface sheet 2 to the absorbent body 4. By forming the longitudinal groove portion 7 so that the surface sheet 2 to the absorbent body 4 are integrated, for example, since the groove is formed on the surface sheet 2 side, the diffusion of the excrement transferred to the surface sheet 2 can be alleviated. The groove width of the longitudinal groove portion 7 is exemplified by, for example, 2.3 mm. Further, in the vertical groove portion 7, a central concave portion 71, a front concave portion 72, and a rear concave portion 73 which are formed in a concave shape in the width direction (WD) are provided in the central portion or (C). In other words, the central recess 71, the front recess 72, and the rear recess 73 are provided in a range in which the pocket portion 62 is formed. Further, the central concave portion 71 has a smaller amount of depression in the width direction (WD) than the front concave portion 72 and the rear concave portion 73. Further, the amount of depression in the width direction (WD) of the front concave portion 72 and the rear concave portion 73 becomes the same amount. As a position at which the bottom portions of the central recess 71, the front recess 72, and the rear recess 73 are formed, the bottom of the front recess 72 may be provided from the end of the front side (F) of the pocket portion 62 in the longitudinal direction (LD). Further, the position of 20 mm, the distance between the bottom of the front recessed portion 72 and the bottom of the rear recessed portion 73 (LD), is exemplified as 45 mm. Further, the distance between the bottom of the front recessed portion 72 or the rear recessed portion 73 and the width direction (WD) of the bottom of the central recessed portion 71 is exemplified as 4 mm. Further, the central recess 71, the front recess 72, and the bottom of the rear recess 73, -14-200932199, include the central recess 71, the front recess 72, and the innermost inner side of the rear recess 73 in the width direction (WD). [1.4] Acting In the above configuration, the sanitary napkin 1 can be appropriately deformed by providing the central recess 71, the front recess 72, and the rear recess 73. For example, when the sanitary napkin 1 is worn, when a force is applied to the width direction (WD) of the sanitary napkin 1 from the thigh portion of the wearer, the force is transmitted from the both side edges to the setting. The longitudinal groove portion 7 of the sanitary napkin 1 having a high rigidity. Further, although the overall shape of the sanitary napkin 1 is deformed by the force transmitted to the vertical groove portion 7, in this case, the conventional sanitary napkin of the conventional type is a groove structure having only one recess in the central region. The force will concentrate on the recess in the longitudinal groove. In addition, when the force is concentrated in one concave portion, the sanitary napkin is made to have a starting point in the longitudinal direction (LD) of the pocket portion of the concave portion and the sanitary napkin, and is oriented toward the inner side of the width direction _ (WD) of the concave portion.

However, in the case where the sanitary napkin is deformed at three points, the width direction (WD) applied to the both end portions of the pocket portion by the force and the direction toward the inner side in the width direction (WD) of the concave portion can be used. The outer force causes the leakage preventing wall 61 to be erected. However, since the three points are deformed from the starting point, the leakage preventing wall 61 can be in an upright state as long as it is narrow. On the other hand, as for the sanitary napkin 1 of the present embodiment, the recesses of the two points of the front recessed portion 72 and the rear recessed portion 73 are provided in the vicinity of the pocket portion 61, and are received from the wearer. When the force of the thigh is transmitted to the longitudinal groove portion 7, it can be dispersed to two points. Thereby, the side sheet 6 can be deformed by the four points of the two points of the longitudinal groove portion 7 and the two ends of the longitudinal direction (LD) of the pocket portion 62. Thereby, between the front recessed portion 72 and the rear recessed portion 73 and the four points of the both end portions of the longitudinal direction (LD) of the pocket portion 62, the starting point of the leakage preventing wall 61 can be erected, and between the front and rear recessed portions 72 and 73, The wide range of the leakage preventing wall 61 is erected on the side of the skin abutting surface. Therefore, even if the sanitary napkin 1 is deformed at the time of wearing, since the erecting is formed in the wide range of the leakage preventing wall 61, it is difficult for the excrement to adhere to the outer side of the leakage preventing wall 61, in short, When the tendon abutment surface side of the side sheet 6 of the pocket portion 62 is less likely to pass through the surface of the side sheet 6 of the pocket portion 62 on the skin contact surface side, the excrement such as body fluid leaks into the sanitary napkin 1 external. Further, by providing the central recess 71 having a small amount of depression (inside) in the width direction (WD), the shape of the vertical groove portion 7 can be adjusted to match the curvature of the wearer's thigh portion. In other words, the surface that receives the force of the central portion (C) can be enlarged, and the force of the front concave portion 72 and the rear concave portion 73 provided before the longitudinal direction (LD) of the central concave portion 71 can be imparted. Further, since the force from the thigh of the wearer is received, since the thigh is a curve, the force is applied to the central region (C) at the point of contact. However, by providing the central concave portion 71 which is formed in the concave direction inside the width direction (WD) of the sanitary napkin 1, the vertical groove portion 7 of the central portion (C) can be brought into contact with the entire curved portion of the thigh portion, even in In the case where the position of the applied force is changed during walking, -16-200932199, the unevenness of the force transmitted in the front-rear direction is not caused, and stable deformation can be performed. [1.5] Others In the present embodiment, the front concave portion 72 and the rear concave portion 73 are provided as concave portions recessed in the width direction (WD) of the sanitary napkin 1 in the vertical groove portion 7, but the present invention is not limited thereto. For example, a plurality of identical recesses can also be provided. Further, a plurality of vertical groove portions may be provided in the width direction (WD). Further, in the present embodiment, the vertical groove portion 7 forms a rigid region by the high pressure press portion and the low pressure press portion, but the present invention is not limited thereto. For example, the longitudinal groove portion 7 may be formed only by the high pressure press portion or only by the low pressure press portion to form a shape having no unevenness. Further, the high pressure press portion or the low pressure press portion may not be formed in the entire groove width of the vertical groove portion 7, and a high pressure press portion or a low pressure press portion may be formed in a part of the groove width. Further, the shape of the high pressure press portion or the low pressure press portion may be formed by a dot shape or the like in addition to the heart shape of the present embodiment, and is not particularly limited. Further, in the present embodiment, the vertical groove portion 7 is formed to press the surface sheet 2 to the absorber 4, but the present invention is not limited thereto. For example, it may be formed only partially in the absorber 4. Further, in the present invention, the groove width of the vertical groove portion 7 is 2.3 mm, but the present invention is not limited thereto. For example, the groove width of the vertical groove portion 7 may be in the range of U to 4. 〇mm. When it is less than 1. 〇mm, the sanitary napkin 1 which is too thin in the press section is broken, so that it is not possible to fully integrate it. Moreover, if it is 4 mm or more, the rigidity is too high, and therefore there is a fear that the wearer will feel uncomfortable. Further, in the present invention, the surface portion 2 and the side sheet 6 are bonded to each other by the hot-melt adhesive, but the present invention is not limited thereto. For example, the surface sheet 2, the side sheet 6, and the intermediate sheet 5 may be bonded together in an integrated manner. Moreover, the absorber 4 can also be integrated and integrated at the same time. Further, the hot melt adhesive may be applied by a predetermined pattern to form a bonding portion. Also, it can be bonded by embossing. Further, it is preferable that the shape of the sheet is adhered by hot embossing from the viewpoint of strength and cost at the time of pasting. Further, in the present embodiment, the first bonding portion 81 and the second bonding portion 82 are provided as the bonding portion 8, but the present invention is not limited thereto. For example, the surface sheet 2 and the side sheet 6 may be bonded together only by the second bonding portion 82. Further, the first bonding portion 81 is provided on the surface sheet 2 side, and is provided on the side of the back sheet 3, for example, on the side of the back sheet 3, and on the side sheet 6 side, in addition to the surface sheet 2 and the side sheet 6. Fit. In short, the first bonding portion 81 may be provided on the inner sheet side. Further, in the present embodiment, the distance between the front concave portion 72 and the bottom portion of the rear concave portion 73 is 45 mm', but the present invention is not limited thereto. For example, the distance between the front concave portion 72 and the bottom portion of the rear concave portion 73 may be in the range of 30 to 120 mm. When the distance between the front concave portion 72 and the bottom portion of the rear concave portion 73 is 30 mm or less, the distance between the front concave portion 72 and the rear concave portion 73 is too short, and the length of the upright portion of the leakage preventing wall 61 is short, so that sufficient leakproofness cannot be maintained. Sex. Further, when the distance between the front concave portion 72 and the bottom portion of the rear concave portion 73 is 120 mm, the distance between the front concave portion 72 and the rear concave portion 73 is too wide, so that the force applied to the vicinity of the thigh portion is less likely to be dispersed. Further, in the present embodiment, the distance between the end portion of the pocket portion 62 and the bottom portion of the front recess portion 72 or the rear recess portion 73 is 20 mm, but the present invention is not limited thereto. For example, it may be in the range of 5 to 100 mm. Once it is 5 mm, the distance between the bottom of the front recessed portion 72 or the rear recessed portion 73 and the end portion of the pocket portion 62 is too short, so that it is less likely to serve as a starting point for the leak-proof wall to stand upright. In addition, when it is 100 mm or more, the force applied to the inside of the excessively long front recessed portion 72 or the rear recessed portion 73 and the force applied to the outer side of the end portion of the pocket portion 62 are less likely to follow the leakage preventing wall, so that it is difficult to promote upright. Further, in the present embodiment, the distance between the bottom portion of the front recessed portion 72 or the rear recessed portion 73 and the bottom portion of the central recessed portion 71 in the width direction (WD) is 4 mm, but the present invention is not limited thereto. For example, it may be in the range of 2 to 25 mm, and preferably it may be in the range of 3 to 15 mm. When it is 2 mm or less, the bottom of the front recessed portion 72 or the rear recessed portion 73 has almost no difference from the bottom of the central recessed portion 71, so that it is difficult to disperse the force to the front recessed portion 72 and the rear recessed portion 73 located at the front and rear. Further, once it is 2 5 mm or more, the curvature of the central concave portion 71 is not small, and it is practically impossible to achieve the shape of the leg with such a small curvature, thereby causing discomfort. [2] Other Embodiments The second embodiment to the fourth embodiment of the present invention will be described with reference to Figs. 3 to 6 . In the second embodiment, another embodiment in which the lateral groove portion 74 formed in the width direction (WD) is formed in the front end portion of the longitudinal direction (ld) is shown. The third embodiment shows another embodiment in which the bonding portion 8 is formed by a discontinuous pattern shape. The fourth embodiment is another embodiment of the so-called nighttime form of the sanitary napkin 1 of -19-200932199. In the following embodiments, portions that are not particularly described are the same as in the first embodiment, and the same reference numerals are attached to the same reference numerals as in the first embodiment. [2.1] Second Embodiment A sanitary napkin 1 A according to a second embodiment of the present invention will be described with reference to Fig. 3. As shown in Fig. 3, the sanitary napkin 1A of the second embodiment extends in the width direction (WD) at the front and rear end portions of the longitudinal direction (LD), and is formed with a lateral groove portion connected to the vertical groove portion 7. 74. The lateral groove portion 74 is formed by connecting end portions of the pair of vertical groove portions 7 to each other. As described above, by forming the lateral groove portion 74, a groove portion that surrounds the core portion 40 formed by the vertical groove portion 7 and the lateral groove portion 74 is formed. The sanitary napkin 1A of the second embodiment is provided in the lateral groove portion 74 extending in the width direction (WD), and thus, for example, the deformation of the front concave portion 72 and the rear concave portion 73 is not inhibited, and even in the sanitary napkin After the use of 1A, it is also possible to restore the shape of the width direction (WD) of the sanitary napkin 1A. Further, by providing the front concave portion 72 and the rear concave portion 73, the leakage preventing wall 61 can stand upright on the skin contact surface side. However, in this case, it is easily disposed in the front concave portion 72 and the rear concave portion after use. 73 is closer to the lateral groove portion 74 at the front and rear end portions of the longitudinal direction (LD), and returns the sanitary napkin 1A in the width direction (WD). Further, the inner side surface of the leakproof wall 61 that has stood upright at this time is returned to the original position. In this way, since the sanitary napkin 1A is used, the inner side surface of the leak-proof wall 61 which has been contaminated during use is entangled in the inside of the sanitary napkin 1A after the use of the physiological -20-200932199 Reduce the visual discomfort after use. Further, even in the case where the sanitary napkin after use is discarded, it is difficult to allow the excreted material that has been absorbed once to leak out of the sanitary napkin 1 . The distance between the outer end portion of the lateral direction (LD) of the lateral groove portion 74 and the bottom portion of the front concave portion 72 or the rear concave portion 73 may be, for example, 50 mm. Further, in the present embodiment, the distance between the outer end portion of the lateral direction (LD) of the lateral groove portion 74 and the bottom portion of the front recess portion 72 or the rear recess portion 73 is 50 mm, but the present invention is not limited thereto. For example, it is only required to be in the range of 5 to 100 mm. When it is 5 mm or less, since the lateral groove portion 74 is too close to the front concave portion 72 or the rear concave portion 72, the lateral groove portion 74 is prevented from being deformed inward in the width direction (WD) of the front concave portion 72 or the rear concave portion 73. Further, when it is set to 100 mm or more, since the distance between the lateral groove portion 74 and the front concave portion 72 or the rear concave portion 72 is too long, it is difficult to reduce the deformation in the width direction (WD) of the front concave portion 72 or the rear concave portion 73. Further, the lateral groove portion 74 can stop the flow of the excrement in the case where the excretion flow is in the longitudinal direction, for example, and is provided at the both ends of the absorbent body 4 of the sanitary napkin 1A. The position of ~60mm is suitable. Thereby, leakage of excrement can be effectively prevented. Further, in the present embodiment, the vertical groove portion 74 is provided before and after the longitudinal direction (LD), but the present invention is not limited thereto. The lateral groove portion 74 may be provided in the central portion (C), the front side (F), and the rear side (R), and may be plural. For example, the bottom of the front recess 72 or the bottom of the rear recess 73 may be formed to be connected to each other. In addition, the shape, the number of the strips, and the width may be different in the longitudinal direction (LD). - 200932199 [2.2] The third embodiment will be described with reference to the fourth embodiment of the sanitary napkin according to the third embodiment of the present invention. 1 B. As shown in Fig. 4, the sanitary napkin 1B of the third embodiment is a compressed surface sheet 2 and an intermediate sheet 5, and the surface sheet 2 and the intermediate sheet 5 are bonded together, and the compressed portion 8B is intermittently The shape of the sex is formed. For example, a graphic shape such as a flower pattern is formed. By forming the compressed portion 8B into a pattern shape, the bonded portion and the non-bonding portion are formed in the compressed portion 8B, and the compressed portion 8B becomes intermittent. The compression unit 8B includes a first compression portion 81B extending in the longitudinal direction (LD) and a longitudinal direction of the central region (C) in the central region (C) of the longitudinal direction (LD) of the sanitary napkin 1B. LD) The front side (F) and the rear side (R) of the both end portions, and the second compression portions 82B and 83B extending in the longitudinal direction (LD). The first compression portion 81B is formed on the outer side in the width direction (WD) of the sanitary napkin 1B closer to the second compression portions 82B and 83B. Specifically, the first compression portion 81B is formed such that the inner edge 81a' of the width direction (WD) of the first compression portion 81B is closer to the outer side than the inner edges 82a and 83a of the width direction (WD) of the second compression portions 82B and 83B. . Further, the compression width in the width direction (WD) of the first compression portion 81B is exemplified by 1.5 to 10 mm. Further, the compression width in the width direction (WD) of the second compression portions 82B and 83B is, for example, 2.0 to 15 mm. Further, the compression width in the width direction (WD) of the first compression portion 81B is narrower than the compression width in the width direction (WD) of the second compression portions 82B and 83B by -22 to 200932199, thereby forming a pocket. Section 62. In the physiological sanitary napkin of the third embodiment, the flower shape of the predetermined shape is continuously formed as the compression portion 8 B, and one of the wrinkles of the pocket portion 62 is divided into a plurality of wrinkles, and the sanitary napkin is used. In the case where 1B is bent along the direction of the wearer (LD), there is a case where one of the pocket portions 62 is wrinkled. On the other hand, by forming the compressed portion 8B in a discontinuous manner, the portion where the wrinkles are generated can be scattered to the non-bonding portion of the compressed portion 8B. Thereby, a large wrinkle of the portion 62 can be divided into a plurality of wrinkles, and the width of the second compressed portions 82B and 83B can be made wider than the width of the first compressed portion 81B by the width of the second compressed portions 82B and 83B.

Borrowing | With the side sheet 6 fit, it will be stronger when subjected to many repeated pressures _ 82B, 83B. Therefore, it is possible to prevent the body fluid that is being worn from leaking out of the broken portion. Although the respective patterns are spaced apart from each other, for example, oxygen is not limited thereto. For example, it is sufficient to form a gap of 0.5 to 15 mm in at least the direction (LD) between the respective patterns. When the thickness is less than 0.5 mm, the ability to divide the wrinkles becomes smaller. When the thickness is less than 5 mm, it is not possible to sufficiently cause the leakage of the bonding portion. 1 B, which can be produced by breaking. For example, in the body, the force generated by the shape of the large square in the rectangular portion is generated, and the force is generated in the direction of the pocket twist (WD) (WD), each tfc, the surface sheet 2 The second compression portion of J is broken, and it is also possible to prevent Wu from being 1.0 mm, but part of it is long, for example, once it is. In the fourth embodiment, the sanitary napkin 1C according to the fourth embodiment of the present invention will be described with reference to Figs. 5 and 6 . In the sanitary napkin 1C of the fourth embodiment, the elastic material 63 is disposed on the inner edge portion of the side sheets 6, 6 as shown in Fig. 5 and Fig. 6 . In the sanitary napkin 1C' of the fourth embodiment, by arranging the elastic material 63 at the inner edge portion of the side sheet 6'6, the erectability of the leakage preventing wall 61 can be improved by the elastic force of the elastic material 63. Further, the sanitary napkin 1C of the fourth embodiment has a length in the longitudinal direction of 250 to 42 mm, and is suitably used as a so-called night type. In the present embodiment, the inside of the width direction (WD) of the sanitary napkin 1C is erected, but the present invention is not limited thereto. For example, the cross section may be formed in an L shape, or the cross section may be formed into a braided hem. [3] Each structure is described below with respect to each structure. [3.1] Side sheet The side sheet 6 is not particularly limited as long as it is a liquid-impermeable sheet-like material. For example, thermoplastic thermoplastic fibers can be used or water repellency treatment can be applied to improve leakproofness. Further, for example, a water repellent treatment may be used for a hydrophilic material such as cotton or a slurry which is a natural material, and the material may be mixed. -24- 200932199 Thermoplastic hydrophobic chemical fiber, for example, a fiber made of polymerized PE and PP such as polypropylene (PP) or polyethylene terephthalate (PET), and a core-sheath structure Further, the web forming of the non-woven fabric may be carried out by a dry method or a wet method such as a viscous method, a melt blow method or an air laid method, or a combination thereof.

Further, in order to improve the leakproof property, it is also possible to form a spun bond, a melt-spray, a spunbond, or the like between fibers. [3.1.3] Wettability Ethylene (PE), single fiber, blended fiber. Any one of the carding method and the knot method, for example, can also be used as an example to demonstrate the use of water flow and leakage in the case of eccentric type, left type, etc., high leakage resistance, microfiber, -25- 200932199 wettability, In order to hinder the penetration of the liquid, the water repellency can also be improved by performing a raising treatment. [3.1.4] Other additional members As the additional member, in order to improve the whitening property, for example, an inorganic filler such as titanium oxide, barium sulfate or calcium carbonate may be contained. For example, in the case of using a core-sheath type composite fiber, it may be contained only in the core or in the core and the sheath. 3.2 [3.2] Surface sheet The surface sheet 1 is not particularly limited as long as it is a liquid permeable sheet-like material. For example, in the case of using a woven or non-woven fabric, the woven or non-woven fabric may use natural fibers or use chemical fibers. As the natural fiber, cellulose which pulverizes a slurry, cotton, or the like is exemplified. As the chemical fiber, semi-synthetic cellulose such as regenerated cellulose, acetate, triacetate, or the like, thermoplastic thermoplastic polymer fiber, or hydroformation treated with hydrophilization is exemplified. Hydrophobic chemical fiber. As the thermoplastic hydrophobic chemical fiber, a single fiber such as polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET), or a fiber obtained by incorporating polymerized PE and PP, and a core can be used. A composite fiber such as a sheath structure. Further, in the thermoplastic hydrophobic chemical fiber, a fiber having high heat sealability is used in order to sufficiently maintain the bonding strength with the embossed portion. For example, a fiber having a linear PE, a low-density PE, a high-density PE, or the like in a sheath structure, a PE or a PET sandwiched between PE, and a sheet-like shape may be added to a short-form -26-200932199 shape. In this way, it is possible to more firmly retain the embossing heat using embossing, and also to absorb a small amount of menstrual blood or sweat which remains on the skin, and may also contain a slurry, a chemical slurry, a hydrazine, an acetate. A cellulose-based liquid hydrophilic fiber such as natural cotton. Further, since it is difficult for the cellulose-based fibers to discharge the liquid which has been absorbed once, the weight of the surface sheet is preferably in the range of 0.1 to 5.0% by weight. Further, in the case where the intermediate sheet 5 is mixed or the surface sheet 2 is formed of a plurality of layers, it is preferable to mix the layers other than the outermost layer. As the nonwoven fabric, a method such as a carding method, a spunbonding method, a meltblowing method, an airlaid method, or the like, which is dry or wet, or the like, may be exemplified. Further, as a method of bonding, methods such as a thermal knot method, a needle sticking method, a chemical bonding method, and the like are exemplified. Further, it is also possible to use a hydrojet entanglement method to form a sheet-like spunlace. [3.2.1] Fiber diameter As the fiber shape, for example, a core-sheath type in which the melting point of the core component is higher than the sheath component, a eccentric type of the core sheath, and a parallel type in which the melting points of the left and right components are different are exemplified. Further, it is also possible to mix a hollow type, a flat type, a Y-shaped, a C-shaped, or the like, a three-dimensional crimped fiber which is sometimes crimped or curled, and a physical load which is divided by a water flow, heat, embossing or the like. Dividing fibers and the like. In addition, the fiber used for the skin contact surface side is a so-called surface sheet 2, and in order to maintain heat-sealing, on the one hand, the fiber is raised to form a soft volume, and the core is polyethylene terephthalate or sheath. It is suitable for the -27-200932199 core sheath type of polyethylene. [3.2.2] Fineness As the fineness, once the inflow of body fluid is taken into contact with the skin, the example is 1.1 to 8.8 dtex. [3.2.3] Wetting property As the wettability, when the influx and rewetting of the body fluid are taken into consideration, the hydrophobic synthetic fiber may be mixed with a hydrophilic agent, a water repellent or the like, or a hydrophilic agent or a water repellent may be applied. Further, it is also possible to impart hydrophilicity by corona treatment and plasma treatment. [3.2.4] Other additional members As the additional member, in order to improve the whitening property, for example, an inorganic filler such as titanium oxide, barium sulfate or calcium carbonate may be contained. For example, in the case of using a core-sheath type composite fiber, it may be contained only in the core or in the intermediate sheet of the core and [3.3] intermediate sheet, and the same material as the surface sheet 2 may be used. Further, a resin film which forms a plurality of liquid permeable holes having liquid permeability and a mesh sheet having a plurality of meshes are also used. Further, the intermediate sheet 5 takes into consideration the introduction property of the liquid, and a portion of the intermediate sheet 5 is disposed at a density higher than that of the periphery thereof, or the intermediate sheet 5 itself has a density increase and decrease rate, and - 28- 200932199 It is advisable to give differences in hydrophilicity. [3.4] Absorber The absorber 4 is only required to be able to retain the absorption of the liquid. Moreover, it is suitable for a large volume, a small appearance, and a chemical stimuli. For example, semi-synthetic cellulose, granular polymer, fiber such as regenerated cellulose, acetate, or triacetate such as cellulose, strontium, and fibril, which are pulverized slurry, cotton, or the like, alone or in combination, can be exemplified. Polymers, thermoplastic hydrophobic chemical fibers, or thermoplastic hydrophobic chemical fibers subjected to hydrophilization treatment, air-laid pastes chemically treated, and the like. Further, although the method of forming the materials on the absorbent body is not particularly limited, it can be molded by, for example, an air laid method, a melt blow method, a spunlace method, or a papermaking method. Further, a cellulose foam, a continuous foam of a synthetic resin, or the like can also be used. Further, it is also possible to form an absorbent body after pulverizing the foam or the flaky material. For example, it is exemplified to have a range of 80 to 100% in the range of the slurry, 20 to 0% of the granular polymer, and after coating with the wiper, the basis weight of the sheet is embossed by embossing to 2000 g/ An absorber of m2, a volume of 1 to 50 nm. The embossing process is for preventing the collapse of the outer crucible of the absorber, and the embossed area ratio is exemplified as a range of 10 to 100%, preferably 30 to 80%, and other examples of the material of the thin absorber are exemplified by absorption. Sheets and polymer sheets. The absorbent sheet and the polymer sheet are generally used as long as -29-200932199 is an absorbent article for sanitary napkins and the like, and may be used without particular limitation. However, the thickness is preferably 0.3 to 5.0 mm. As the absorbent sheet, a slurry sheet obtained by flaking an absorbent paper, a nonwoven fabric or a fiber with a binder or the like is exemplified. As the polymer sheet, a sheet in which a pulverized slurry and a fiber-mixed particulate polymer are formed into a sheet form is exemplified. As the sheet-like sheet in which the fiber-mixed particulate polymer is formed, any one of the particles in which the particulate polymer is dispersed and formed into a layer may be used. As the material for forming the absorbent sheet and the fiber to be applied to the polymer sheet, for example, a cellulose fiber such as wood pulp, a regenerated cellulose fiber such as cerium or copper amine, or a polymer which hydrophilizes the surface of the fiber with a surfactant is used. Ethylene, polypropylene, polyethylene terephthalate, polyethylene/polypropylene composite fiber, polyethylene/polyethylene terephthalate composite fiber are preferred. Further, in consideration of maintaining hydrophilicity well, it is preferred to use cellulose fibers. Further, as the particulate polymer applied to the polymer sheet, it is preferred to absorb and retain a liquid having a weight of 20 times or more and gel. For example, starch and croscarmellose, polyacrylic acid and salts thereof, and polyacrylate graft polymers are exemplified. [3.5] Inner sheet The inner sheet 3 is not particularly limited as long as it is a liquid permeable sheet-like material. For example, it is highly suitable to use a film such as a film mainly composed of PE, PP, or the like, an air-permeable resin film, a non-woven fabric such as a spun bond type or a spunlace type, and a breathable resin sheet. In order to prevent the softness of the feeling of wearing -30-200932199, for example, a film obtained by using a low-density polyethylene (LDPE) resin as a main component having a basis weight of 15 to 30 g/m2 is preferable. [3.6] Fixing material As a fixing material for underwear and the like, a hot-melt type adhesive can be used. The hot-melt type adhesive is preferably viscous at normal temperature, and is exemplified by a pressure-sensitive adhesive. Specifically, an example is shown in which the SEBS is 15 to 25%, the plasticizer is 15 to 35%, and the tackifier is 40 to 70%. In addition, an oxidation inhibitor, a fluorescent inhibitor, etc. may be added in the range of 〇·1 to 1·〇%. For example, the weight per unit area is 10 to 200 g/m2, which is applied by a coater, a bead coating, or the like, and is applied in a uniform, striped, or dot-like pattern. Further, a propylene-based adhesive can also be used. In the present embodiment, the fixing material is a rubber-based hot-melt type adhesive having a basis weight of 25 g/m 2 and coated by a coater having a width of 5 mm and a coating of six coats of 5 mm. _ As another example, a plurality of hooks erected on the surface of the tape portion and the surface of the tape portion are exemplified. In the above-mentioned production method, a thermoplastic synthetic resin such as polypropylene is extruded, and a rib structure portion integrally formed with the tape portion is subjected to a treatment such as cutting or cutting, and a hook portion is formed on the surface of the tape portion. Further, the loop of the monofilament fiber formed of the thermoplastic synthetic resin provided on the surface of the tape portion is cut by the side to form a hook portion. Furthermore, in order to reduce the risk of injury to the skin, the end faces of the hooks may be rounded. For example, the shape of the mold can be used to make the top of the hook have a circular shape. Furthermore, the cross-sectional shape of the hook portion is not particularly limited, and the example has a tapered shape and a T-shape -31 - 200932199
