Description

  The present invention relates to a urine collection pad.

  There has been known an absorbent article including an absorbent main body including an absorber and a pair of leakage barriers. In order to suppress leakage of excretory fluids such as urine from the end in the width direction of the absorbent article, that is, side leakage, the leak-proof wall is located at each of both ends in the width direction of the absorbent main body, and in the longitudinal direction. It extends so as to continuously extend over both end portions of the lip, and is formed so as to stand up toward the skin surface of the wearer. As an absorptive article which has such a leak-proof wall, the absorptive article indicated by patent documents 1 (Unexamined-Japanese-Patent No. 2010-094321) is mentioned, for example.

  The absorbent article of Patent Document 1 has a substantially sheet-like main body portion in which an absorbent core is disposed between a back sheet and a top sheet, and substantially the entire length in the longitudinal direction of the main body portion on both sides of the main body portion. A pair of side seats provided across the board. Each of the pair of side sheets is a part on one side of a fold line provided over the entire length in the longitudinal direction, and a belt-like joint part joined to the main body part and the other side of the fold line. It is a part and is folded toward the outer side in the width direction at the inner edge in the width direction perpendicular to the longitudinal direction of the joint, which is the fold line, and further folded toward the inner side in the width direction. And a part of the side wall portion standing up from the main body portion. The side wall portions are continuous from the two side wall end portions between the two side wall end portions and between the two side wall end portions, and from the fold line, between the two side wall end portions. A standing part that stands up; and an elastic member that is disposed over substantially the entire length of the standing part in the longitudinal direction and contracts to form the gathers by contracting the standing part. One side wall end portion of the two side wall end portions is a portion continuing from the upright portion, and the elastic member is disposed and is not joined to the joint portion and the main body portion, and the elastic A semi-standing part standing up from the main body part lower than the standing part by contraction of the member, and a fixing part adjacent to the outside of the semi-standing part in the width direction and fixed on the joint part. Prepare. According to Patent Document 1, this absorbent article can prevent side leakage from the vicinity of the end in the longitudinal direction of the absorbent article.

JP 2010-094321 A

  In the absorbent article, in order to further suppress the side leakage, as a method of raising the leakage prevention wall more appropriately, for example, there is a method of increasing the degree of expansion and contraction of the elastic member of the leakage prevention wall. Here, unlike a sanitary napkin, a tape-fixed diaper, a pants-type diaper, or the like, some urine removing pads are placed on an exterior body that is repeatedly used and worn without being fixed. In the case of a urine-absorbing pad that is not fixed to the exterior body, a state (natural state) in which the urine-absorbing pad is taken out from the package and opened (a natural state) is generally a form when worn. Therefore, when the degree of expansion and contraction of the elastic member is increased, the absorbent main body portion contracts too much in the longitudinal direction during wearing, and the absorbent main body portion is likely to be separated from the skin surface, and thus may not be properly worn. In addition, the urine absorbing pad contracts too much in the longitudinal direction and looks small, and the wearer may feel anxious. Also, even if the urine collecting pad is fixed to the exterior body, if it is not fixed properly, or if the wearer's movement is unusual, it will be worn properly. May be difficult. This also applies to an absorbent article such as the absorbent article of Patent Document 1 in which a leak-proof wall is provided in as wide a range as possible in the longitudinal direction (standing part and semi-standing part) to prevent side leakage.

  Therefore, the present inventor uses a technique of narrowing the range in which the elastic member on the leak-proof wall can expand and contract, which may be considered disadvantageous for preventing side leakage at first glance, while preventing the elastic member from contracting too much. Then, the structure for raising the leakage barrier more appropriately was examined. In this case, it can suppress that an absorption main-body part shrink | contracts too much in a longitudinal direction, and an absorption main-body part leaves | separates from the skin surface. Moreover, it can suppress that a urine picking pad looks small in a longitudinal direction.

  However, when the range in which the elastic member on the leak-proof wall can expand and contract is narrowed in this way, the width in the longitudinal direction of the region of the absorption main body that supports expansion and contraction of the elastic member in the vicinity of both ends of the elastic member becomes narrow. The region of the absorption main body portion that supports expansion and contraction of the elastic member is a boundary portion of the absorption main body portion corresponding to a boundary region between a range in which the elastic member can expand and contract and a range in which the elastic member does not exist or does not expand or contract. As a result, a relatively large force is applied to the boundary portion of the absorption main body portion, and the boundary portion of the absorption main body portion is deformed to bend downward from the upper side in the thickness direction, that is, from the skin facing surface side. There is a risk that deformation that is recessed toward the skin non-facing surface side may occur. If this happens, deformation of the boundary portion of the absorbent main body will cause deformation in the boundary region of the leak-proof wall, reducing the force with which the leak-proof wall contacts the skin surface, or a gap between the leak-proof wall and the skin surface. May occur. Further, since the boundary region of the leak-proof wall is a region where the leak-proof wall starts to rise, the degree of standing is reduced. As a result, even when the leak-proof wall stands up toward the wearer's skin surface during wearing, there is a possibility that a state in which the leak-proof wall is difficult to adhere to the skin surface in the boundary region may occur.

  Accordingly, an object of the present invention is to suppress lateral leakage in a boundary region between a range in which the elastic member can be expanded and contracted and a range in which the elastic member does not exist or does not expand and contract while narrowing the range in which the elastic member in the longitudinal direction can expand and contract. An object of the present invention is to provide a urine absorbing pad capable of being used.

  One aspect (aspect 1) of the present invention has a longitudinal direction, a width direction, and a thickness direction, and has an abdominal region, a crotch region, and a back region in the longitudinal direction, and an absorbent main body portion that includes an absorbent body; A urine absorbing pad that is located at each of the widthwise ends of the absorbent main body and includes a pair of leak-proof wall portions extending continuously across the lengthwise ends, Each of the pair of leak-proof wall portions is opposed to the absorption main body portion, at least a base portion in which an outer side edge in the width direction is fixed to the absorption main body portion, and an inner side in the width direction of the base portion A first wall portion that is connected to the side edge and rises toward the skin-facing surface side when worn, and is connected to an outer side edge in the width direction of the first wall portion, and on the skin-facing surface side when worn. A second wall that stands up toward the base, and at least the abdomen region, the base and the first wall A first joint portion having a predetermined length in the width direction and extending inward from an edge of the leak-proof wall portion in the longitudinal direction, and at least in the abdominal region, the first wall portion A second joining portion joined to the second wall portion, having a predetermined length in the width direction, and extending inward from an end edge of the leak-proof wall portion in the longitudinal direction, A joining main body located on an edge side of the leak-proof wall, and a joining extension extending from the outer side in the width direction of the joining main body to the inner side in the longitudinal direction. A second joint portion including the second joint portion extending in the longitudinal direction from the inner edge of the joint body portion in the abdominal region or the position on the inner side thereof in the longitudinal direction to the back region and aligned in the width direction. A plurality of elastic members arranged in such a manner that the second wall portion includes the plurality of elastic members. An elastic member located on the second wall portion of the elastic member has a stretchable region extending in the longitudinal direction, and a non-stretchable region located on both outer sides in the longitudinal direction of the stretchable region, The joint extending portion is a urine collecting pad that is extended by a predetermined length in the longitudinal direction toward the inner side in the longitudinal direction on the outer side in the width direction of the stretchable region.

  The urine absorbing pad of the first aspect is arranged such that a plurality of elastic members extend in the longitudinal direction and are arranged in the width direction in the stretchable region of the second wall portion, and the joint extending portion of the second joint portion Is fixed or semi-fixed by a predetermined length in the widthwise direction of the stretchable region. Therefore, in the stretchable region, the longitudinal length of the outer side portion in the width direction is substantially shorter than the longitudinal length of the inner side portion in the width direction. With such a configuration, in the stretchable region of the second wall portion, the outer side portion in the width direction is stretched within a relatively short range in the longitudinal direction, and the inner side portion is relatively long in the longitudinal direction. Can be expanded and contracted. Thereby, the 2nd wall part can be made to stand up more appropriately in the thickness direction. Furthermore, the joint extension part of the second joint part extends from the non-stretchable region to the stretchable region. With such a configuration, the rigidity of the second wall portion can be relatively increased in a region extending from the non-stretchable region to the stretchable region, that is, the boundary region. As a result, even if the deformation that the absorption main body portion bends from the upper side to the lower side occurs in the boundary portion corresponding to the boundary region of the absorption main body portion, the deformation of the boundary region of the second wall portion can be suppressed. A situation in which the force of the skin facing surface of the leaking wall portion coming into contact with the skin surface becomes weak, or a gap is generated between the skin facing surface side of the second wall portion of the leak preventing wall portion and the skin surface. Therefore, it is possible to suppress the side leakage of the excretory fluid in the boundary region. Furthermore, the joint extending portion of the second joint portion extends from the non-stretchable region to the stretchable region, and joins the second wall portion to the first wall portion. With such a configuration, in the boundary region extending from the non-stretchable region to the stretchable region in the second wall portion, the surface on the skin facing surface side of the second wall portion is substantially parallel to the surface on the skin facing surface side of the absorbent main body portion. The shape of the shape can be maintained. Therefore, the contact probability between the surface of the second wall portion on the skin facing surface side and the skin surface can be increased. As a result, in the boundary region where the degree of standing is small due to the structure, the second wall portion having increased rigidity is deformed, and the force that the leak-proof wall portion comes into contact with the skin surface is weakened. Even if there is a gap between the two, the surface of the second wall facing the skin and the skin surface are almost in contact with each other. The movement of excretory fluid can be prevented at the location. Therefore, it is possible to suppress the side leakage of excretory fluid in the boundary region. In this way, in the leak-proof wall part, the second wall part can be more easily stood up to suppress side leakage more easily, while suppressing the occurrence of a gap in the second wall part and easily along the skin surface, Lateral leakage can be further suppressed by bringing the second wall portion into contact with the skin surface and increasing the contact probability.

  Further, in another aspect (aspect 2) of the present invention, in the urine absorption pad according to aspect 1, the absorbent body has a plan view, and in the crotch region, both end edges of the absorbent body in the width direction are A narrow portion that is constricted toward the inner side in the width direction, and the end of the constricted portion on the abdomen region side has a position in the longitudinal direction that is within the range in the longitudinal direction of the joint extension portion. Located in the overlapping area.

  In the urine absorbing pad according to the second aspect, the end portion of the constricted portion having low rigidity in the absorbent body is disposed in a region where the longitudinal position overlaps the longitudinal range of the joint extending portion. That is, the end portion of the constricted portion that is easily deformed in the thickness direction is provided at a position corresponding to the joint extending portion. Here, the rigidity of the part joined to the joint extension part in the second wall part is relatively high. Therefore, even if the end portion of the constricted portion is deformed, the second wall portion can be prevented from being deformed, and a gap is generated between the surface of the second wall portion on the skin facing surface side and the skin surface. The surface of the second wall portion on the skin facing surface side can be gently deformed so as to follow the curved surface of the skin surface.

  In still another aspect (Aspect 3) of the present invention, in the urine absorbing pad according to Aspect 1 or 2, the end on the abdominal region side of the elastic member located on the second wall portion of the plurality of elastic members. The part is located in a region where the position in the longitudinal direction overlaps the range in the longitudinal direction of the joint extension part.

  In the urine absorption pad of the third aspect, the end of the elastic member located on the second wall portion on the abdomen region side is located in a region where the position in the longitudinal direction overlaps the range in the longitudinal direction of the joint extension portion. Therefore, compared to the case where the end portion of the elastic member is on the outer side of the joint extension portion in the longitudinal direction, the bending state when the absorption main body portion bends from the upper side to the lower side in the thickness direction is reduced. It can be made relatively gentle. Thereby, in the part which can bend in the thickness direction in an absorption main-body part, a 2nd wall part deform | transforms and a clearance gap arises between the surface of the skin opposing surface side of a leak-proof wall (2nd wall part), and a skin surface. This can be further suppressed, and the surface of the second wall on the skin facing surface side can be more gently deformed along the curved surface of the skin surface.

  In still another aspect (Aspect 4) of the present invention, in the urine absorbing pad according to any one of Aspects 1 to 3, the absorbent body extends inward from the surface of the absorbent body in the thickness direction, and the longitudinal direction. And at least a part of the opening is located in a region where the position in the longitudinal direction overlaps the range in the longitudinal direction of the joint extension.

  In the urine absorbing pad of the present aspect 4, the absorbent body has an opening (including a case of a through hole), and at least a part of the opening overlaps the longitudinal range of the joint extension portion. Located in the area. That is, at least a part of the portion including the opening in the absorber that is low in rigidity and easily deformed is provided at a position corresponding to the joint extension portion. Here, the rigidity of the part joined to the joint extension part in the second wall part is relatively high. Therefore, even if the portion including the opening in the absorbent body is deformed, it is possible to suppress the deformation of the second wall portion, and there is a gap between the surface of the second wall portion on the skin facing surface side and the skin surface. Generation | occurrence | production can be suppressed and the surface by the side of the skin opposing surface of a 2nd wall part can be made into a moderate deformation | transformation so that the curved surface of a skin surface may be followed.

  In still another aspect (Aspect 5) of the present invention, in the urine absorbing pad according to any one of Aspects 1 to 1, the absorbent body includes a first widthwise region defined by a widthwise central axis extending in the longitudinal direction, and A pair of embossed portions disposed in each of the second regions in the width direction and recessed in the thickness direction from the skin-facing surface, and the end portions of the embossed portions on the abdominal region side in the longitudinal direction are in the longitudinal direction The position is located in a region overlapping the range in the longitudinal direction of the joint extension portion.

  In the urine absorbing pad according to the fifth aspect, the absorbent body includes a pair of embossed portions, and the end of the embossed portion on the side of the abdominal region in the longitudinal direction overlaps the longitudinal range of the joint extending portion. Is located. That is, a portion on the outer side of the end portion in the longitudinal direction of the embossed portion, which is less rigid than the embossed portion and easily deforms, is provided at a position corresponding to the joint extending portion. Here, the rigidity of the part joined to the joint extension part in the second wall part is relatively high. Therefore, even if the outer side portion of the end portion in the longitudinal direction of the embossed portion is deformed, the second wall portion can be prevented from being deformed, and the surface of the second wall portion on the skin facing surface side and the skin surface It is possible to suppress the generation of a gap between the second wall portion and the surface of the second wall portion on the skin facing surface side so that the surface can be gently deformed along the curved surface of the skin surface.

  In still another aspect (Aspect 6) of the present invention, in the urine collecting pad according to any one of Aspects 1 to 5, the stretchable region is located on the inner side in the width direction, and on the outer side in the width direction. It is easier to shrink than the side part.

  In the urine absorption pad according to the sixth aspect, in the stretchable region, the inner side portion in the width direction is more easily contracted than the outer side portion in the width direction. Thereby, the part of the inner side of the width direction in the 2nd wall part can be made easy to stand with respect to the part of the outer side of the width direction. Therefore, the second wall portion can be easily erected and the erected structure can be easily maintained.

  In still another aspect (Aspect 7) of the present invention, in each of the urine absorbing pads according to any one of Aspects 1 to 6, each of the pair of leak-proof wall portions is fixed to the absorption main body portion along the longitudinal direction. The fixed ends joined together and a free end located opposite to the fixed ends in the width direction, and the plurality of elastic members are elastic members located on the fixed end side. The length in the longitudinal direction is longer than the length in the longitudinal direction of the elastic member located on the free end side.

  In the urine absorbing pad according to the seventh aspect, in the plurality of elastic members, the length in the longitudinal direction of the elastic member located on the fixed end side is longer than the length in the longitudinal direction of the elastic member located on the free end side. Therefore, in the portion on the outer side in the width direction of the leak-proof wall portion, it is easy to maintain the standing structure by the first wall portion and the second wall portion, and the durability against the excretion liquid toward the outer side in the width direction is further improved. Can be secured. Moreover, in the inner side part in the width direction of a leak-proof wall part, a freedom degree of a deformation | transformation and a movement is high, and it makes it easy to make a leak-proof wall part contact | adhere, following a wearer's body shape (shape of a crotch part). be able to. Thereby, this urine picking pad can exhibit the leak-proof function of a leak-proof wall part favorably.

  In still another aspect (Aspect 8) of the present invention, in the urine collecting pad according to any one of Aspects 1 to 7, each of the pair of leak-proof wall portions includes the base portion and the first wall in the back region. A third joint portion having a predetermined length in the width direction, extending inward from an end edge of the leak-proof wall portion in the longitudinal direction, and facing the first joint portion in the longitudinal direction In the back region, the first wall portion and the second wall portion are joined to each other, have a predetermined width direction length, and extend inward from the edge of the leakage preventing wall portion in the longitudinal direction. A back joint body part extending and extending to the second joint part and facing the longitudinal direction in the longitudinal direction, the back joint body part located on the edge side of the leak-proof wall part in the longitudinal direction, and the back joint body part in the back joint body part A back joint extending portion extending from the outer side portion in the width direction to the inner side in the longitudinal direction A plurality of elastic members, wherein the plurality of elastic members are, in plan view, an inner edge of the back joint body portion in the back region in the longitudinal direction or the inward side thereof. Extending from the position on the side to the abdomen region, and the back joint extending portion extends a predetermined length in the longitudinal direction toward the inward side in the longitudinal direction on the outer side in the width direction of the stretchable region. It is installed.

  In the urine absorption pad according to the present aspect 8, by having the above-described configuration, the outer side portion in the width direction is expanded and contracted in a short range in the longitudinal direction in the expansion and contraction region of the second wall portion. The side portion can be expanded and contracted in a long range in the longitudinal direction. Thereby, the 2nd wall part can be made to stand up more appropriately in the thickness direction. Further, on the back region side, the rigidity of the boundary region can be relatively increased, whereby even when a deformation in which the absorption main body portion bends from the upper side to the lower side occurs in the boundary portion corresponding to the boundary region of the absorption main body portion, Since the deformation of the boundary region of the second wall portion can be suppressed, the force of the skin facing surface of the leakage preventing wall portion coming into contact with the skin surface becomes weak, or the skin facing surface of the second wall portion of the leakage preventing wall portion It can suppress that a clearance gap arises between the surface of a side, and a skin surface, Therefore The side leakage of the excretion liquid in a boundary area | region can be suppressed. Furthermore, in the back region, in the boundary region where the standing is small due to the structure, the second wall portion having increased rigidity is deformed and the force of the leak-proof wall portion coming into contact with the skin surface becomes weak, or the skin surface is partially Even if there is a gap between the surface of the second wall and the skin facing surface, the surface of the skin is almost in contact with the surface, so any part of the surface while excretory fluid crosses the surface The movement of excretion can be prevented. Therefore, it is possible to suppress the side leakage of excretory fluid in the boundary region. As described above, in the leakage preventing wall portion, not only on the abdominal region side but also on the back region side, the second wall portion can be more easily erected to suppress side leakage, and the gap of the second wall portion can be suppressed. Lateral leakage can be further suppressed by suppressing the occurrence and facilitating along the skin surface, and increasing the contact probability by bringing the second wall portion into contact with the skin surface.

  In still another aspect (Aspect 9) of the present invention, in the urine collecting pad according to Aspect 8, the longitudinal length of the second joint portion in the abdominal region and the longitudinal length of the fourth joint portion in the back region. And the length of the stretchable region in the longitudinal direction is smaller than the total length.

  In the urine absorbing pad according to the ninth aspect, the longitudinal length of the stretchable region is smaller than the total length of the longitudinal length of the second joint portion and the longitudinal length of the fourth joint portion. Therefore, it can suppress that a urine picking pad shrink | contracts too much at the time of wear. Furthermore, when the wearer lies sideways, the region other than the stretchable region of the second wall portion supports the stretchable region of the second wall portion so that the standing shape of the stretchable region is maintained. It can be made difficult to cross the wall.

  In yet another aspect (aspect 10) of the present invention, in the urine collection pad according to any one of aspects 1 to 8, the urine collection pad extends in the width direction at a plurality of folding positions in the longitudinal direction during packaging. Folded along a fold line, and among the plurality of folding positions, the folding position closest to the abdomen region side is the inner edge in the longitudinal direction of the joint extension part of the second joint part. More inward.

  In this urine collection pad, the folding position on the most abdominal region side is on the inner side of the inner side edge in the longitudinal direction of the joint extension portion of the second joint portion. That is, the folding position does not overlap the first joint and the second joint. Therefore, when the folded urine collecting pad is released, the first wall portion and the second wall portion do not have a crease that is liable to cause a side leak, and the second junction portion (joint extension portion) prevents side leakage. The function can be demonstrated effectively.

  According to the present invention, it is possible to suppress lateral leakage in a boundary region between a range in which the elastic member can be expanded and contracted and a range in which the elastic member does not exist or does not expand and contract while narrowing a range in which the elastic member in the longitudinal direction can expand and contract. A possible urine pad can be provided.

In other words, joining the extending portion 45 _O is extended so as to be stretched in the boundary region B _A. In the present embodiment, the bonding extending portion 45 _O, at the outer side in the width direction W in the expansion area S _E, is predetermined longitudinal length extending toward the inner side of the longitudinal direction L. However, the predetermined longitudinal length, a longitudinal length of up to the edge of the boundary region B _A of the telescopic area S _E from the inner side edge 45E _i of the joint main body 45 _i, preferably stretchable region S _This is a length exceeding the edge of the boundary area B _A in _E inward. In the present embodiment, among the predetermined longitudinal length, the length of the stretchable region S _E is the longitudinal length 5-20% of stretchable region S _E, the length of preferably in the range of 10-15% is there. When the predetermined length in the longitudinal direction is within this range, the function of the joint extending portion 45 _O , such as increasing the rigidity of the second wall portion 43, can be sufficiently exhibited. In this embodiment, the elastic member EL2 of the second wall portion 43 of the plurality of elastic members EL overlaps the joint extension portion 45 _O extending in the longitudinal direction L. However, the joint extension portion 45 _O does not have to be in a state where the elastic member EL is completely fixed and cannot be fully expanded and contracted, and may be in a semi-fixed state where a certain degree of expansion and contraction is possible. Then, the stretchable region S _E, a longitudinal length of the inner side portion in the width direction W, and longer than the longitudinal length of the outer-side portion in the width direction W.

The absorber 21 is arrange | positioned in the absorption main-body part 2 by planar view, as shown in FIG. Specifically, the longitudinal direction L in the abdominal region side edge 21E ₂ of the absorbent body 21 (preferably about dorsal region side edge 21E ₁ also in the longitudinal direction L of the joint main body portion 45i of the second joint portion 45 It is located on the outer side in the longitudinal direction L with respect to the inner side edge 45E _i located on the innermost side, and both end edges in the width direction W of the absorber 21 (that is, one side edge in the width direction W). 21E ₃ and the other side edge 21E ₄₎ are abdominal area _{a F} (preferably located on the outer side in the width direction W than the inner side edge in the width direction W of the back area _a even in _B) the base portion 41 .

Next, the operation of the urine collecting pad 1 will be described with reference to FIGS. FIG. 7 is a perspective view of the urine collecting pad 1. In the urine absorbing pad 1, the stretchable region S _E of the second wall portion 43, extends a plurality of elastic members EL1, EL2 are longitudinally L, while being arranged side by side in the width direction W, the second wall portion 43 junction extending portion 45 _O is a part of the outer side in the width direction W of the flex region S _E fixed or semi-fixed predetermined longitudinal length of the. Therefore, in the stretchable region _SE , the longitudinal length of the outer side portion in the width direction W is substantially shorter than the longitudinal length of the inner side portion in the width direction W. With such a configuration, the stretchable region S _E of the second wall portion 43, to extend and retract the portion of the outer side in the width direction W in a short range in the longitudinal direction L, the long portions of the inner side in the longitudinal direction L range Can be expanded and contracted. Thereby, the second wall portion 43 can be more easily erected in the thickness direction T.
Additionally, extending portions 45 _O bonding of the second joint portion 45 is extending over the stretchable region S _E of the crotch region A _C side from the non-stretchable region S _U of the abdominal area A _F side. With this configuration, a region extending portion 45 _O bonding at the second wall portion 43 is present, that is, a region spanning stretchable region S _E from the non-stretchable region S _U, i.e. in the boundary region B _A, relatively the rigidity Can be high. Thereby, as shown in FIG. 7, even if the boundary portion deformable bent downward side from the upper side corresponds to the boundary region B _A of the absorbent main body 2 of the absorbent body portion 2 is the thickness direction T, the second wall The deformation of the boundary area B _A of the part 43 can be suppressed. Therefore, the force by which the skin facing surface of the leakage preventing wall 40 comes into contact with the skin surface becomes weak, or there is a gap between the skin facing surface side of the second wall 43 of the leakage preventing wall 40 and the skin surface. or occurring, it is possible to suppress such a situation that, therefore side leakage excretion solution P in the boundary region B _a can be suppressed.
Additionally, extending portions 45 _O bonding of the second joint portion 45, while being extended over the stretchable region _{S E} of the crotch region _{A C} side from the non-stretchable region _{S U} of the abdominal area _{A F} side, a second wall portion 43 Are joined to the first wall portion 42. With this configuration, as shown in FIG. 3, in the boundary region B _A in the second wall portion 43, the surface of the skin-facing surface side of the second wall portion 43, the skin-facing side surface of the absorbent main body 2 It is possible to maintain a planar shape that is substantially parallel to the surface. Therefore, it is possible to increase the contact probability between the surface of the second wall 43 on the skin facing surface side and the skin surface. As a result, in the boundary region B _A where the degree of standing is small due to the structure, the second wall 43 having increased rigidity is deformed, and the force that the leak-proof wall 40 comes into contact with the skin surface becomes weak. Even if there is a gap between the skin surface and the skin surface, the surface of the second wall portion 43 on the skin facing surface side and the skin surface are almost in contact with each other. As shown in FIG. While the liquid P crosses the surface, the movement of the excretory fluid P can be prevented at any point on the surface. Therefore, it is possible to suppress side leakage liquid waste in the boundary regions B _A.
As described above, in the leakage preventing wall 40, the second wall 43 can be more easily stood up to suppress side leakage, and the generation of a gap in the second wall 43 can be suppressed to easily follow the skin surface. At the same time, side leakage can be further suppressed by bringing the second wall portion 43 into surface contact with the skin surface and increasing the contact probability.

In the urine collecting pad 1 of the present embodiment, as a preferable aspect, each of the pair of leak-proof wall portions 40 and 40 has the same configuration as the first joint portion 44 and the second joint portion 45 in the abdominal region _AF . the is also provided in the back region a _B. That is, each of the pair of leak-proof wall portions 40, 40 has a third joint portion (hereinafter referred to as “third joint portion 44”) similar to the first joint portion 44 in the abdominal region _AF , and the third. A fourth joint (hereinafter referred to as “fourth joint 45”) similar to the two joints 45 is further provided. The third joint portion 44 in the back region A _B, joined to the base portion 41 of the first wall portion 42 has a predetermined length in the width direction, inward from the edge of the leakage preventing walls 40 in the longitudinal direction L It extends to the side and opposes the first joint portion of the abdominal region _AF in the longitudinal direction L. The fourth joint 45, in the back area A _B, the first wall portion 42 joined to the second wall portion 43 has a predetermined length in the width direction, the end of the leakage preventing walls 40 in the longitudinal direction L It extends inward from the edge and faces the second joint 45 of the abdominal region _AF in the longitudinal direction L. The fourth joint 45 is formed in a longitudinal direction L from a back joint body 45 _i located on the edge side of the leak-proof wall 40 in the longitudinal direction L, and a portion on the outer side in the width direction W in the back joint body 45 _i . , And a back joint extending portion 45 _O extending inward. A plurality of elastic members EL are in a plan view, from the inner side edge 45E _i or the inner-side position of the back joint main body 45 _i to the abdominal region A _F in the dorsal region A _B in the longitudinal direction L It extends. Then, back junction extending portion 45 _O, in the outer side in the width direction W of the back area A _B-side of the stretchable region S _E, toward the inner side of the longitudinal direction L, is extended a predetermined longitudinal length ing.

By the above configuration, in this urine absorbing pad 1, in the dorsal area A _B-side as well as the abdominal area A _F side, the stretchable region S _E of the second wall portion 43, the outer side in the width direction W The portion can be expanded and contracted in the longitudinal direction L within a short range, and the inner side portion can be expanded and contracted within a long range in the longitudinal direction L. Thereby, the 2nd wall part 43 can be made to stand up more appropriately in the thickness direction T more appropriately. Further, the rigidity of the boundary region B _A can be relatively increased on the back region A _B side, so that the deformation in which the absorption main body portion 2 bends in the thickness direction T from the upper side to the lower side is not affected by the boundary of the absorption main body portion 2. even if the boundary portion corresponding to the region B _a, it is possible to suppress the deformation of the boundary region B _a of the second wall portion 43. Thereby, the force by which the skin facing surface of the leakage preventing wall portion 40 comes into contact with the skin surface is weakened, or a gap is formed between the skin facing surface side of the second wall portion 43 of the leakage preventing wall portion 40 and the skin surface. Can be suppressed, and therefore side leakage of excretory fluid in the boundary area B _A can be suppressed. Further, in the back area A _B, the structure, the standing small boundary region B _A, or if leakage preventing walls 40 and the second wall portion 43 with increased rigidity is deformed weakens the force in contact with the skin surface Even if a gap is partially formed between the skin surface and the surface of the second wall 43 on the skin facing surface side, the skin surface is almost in contact with the surface, so the excretory fluid crosses the surface. In the meantime, the excretion fluid can be prevented from moving at any point on the surface. Therefore, it is possible suppress side leakage liquid waste in the boundary regions B _A. Thus, the leakage preventing walls 40, also in the dorsal region A _B-side as well as the abdominal area A _F side, while suppressing the side leakage and facilitate better standing the second wall portion 43, the second Side leakage can be further suppressed by suppressing the occurrence of gaps in the wall portion 43 to make it easier to follow along the skin surface and increasing the contact probability by bringing the second wall portion 43 into contact with the skin surface.

In the above-described embodiment, as shown in FIGS. 1 to 6, the absorbent body 21 is between the topsheet 22 and the backsheet 23 in the thickness direction T of the absorbent main body 2 (specifically, the topsheet 22 Between the two and the back film 24) and functions to absorb and retain excretion fluid such as the wearer's urine that has permeated through the top sheet 22 (ie, the first absorbent layer 21A). And the second absorption layer 21B).

These two absorption layers are, in the absorption main body 2, the first absorption layer 21 </ b> A that is relatively disposed on the skin facing surface side and the second absorption layer that is relatively disposed on the non-skin facing surface side. 21B is joined by an arbitrary joining means (not shown) such as a hot-melt adhesive to constitute the above-described absorber 21 as an integrated product. Of the two absorbent layers constituting the absorbent body 21, the first absorbent layer 21 </ b> A is abdominal region A _F in the longitudinal direction L of the absorbent main body 2 (specifically, the abdominal portion in the longitudinal direction L) in plan view. the dorsal region a _{B (specifically} from the side end portion vicinity), extending over the back-side end portion) in the longitudinal direction L. Furthermore, the first absorption layer 21A is formed from the width direction first region A _W1 in the width direction W of the absorption main body 2 (specifically, near one end portion in the width direction W) to the width direction second region A _W2 ( Specifically, it extends over the other side end portion in the width direction W). Overall, the first absorbent layer 21A is longer in the longitudinal direction L, the longitudinal direction L substantially hourglass-shaped outer shape corresponding portion crotch region A _C is constricted narrower toward the inner side in the width direction W of It is comprised by the absorptive member which has. In the present embodiment, the first absorption layer 21 </ b> A forms the outer shape of the absorber 21 in plan view.

However, the width in the direction W, than both edges in the width direction W of the end edges of the widthwise direction W is first absorbing layer 21A respectively (one side edge 21E ₃ and the other side edge 21E 4 in the widthwise direction _W) It extends so as to be located on the inner side in the width direction W. As a whole, the second absorbent layer 21 </ b> B is configured by an absorbent member having a substantially rectangular outer shape that is long in the longitudinal direction L. By forming the second absorbent layer 21B that is relatively disposed on the non-skin facing surface side in this manner, the step at the edge portions in the width direction W of the first absorbent layer 21A and the second absorbent layer 21B is worn by the wearer. It is difficult to perceive.

  In the present invention, the absorbent member that can be used as the first absorbent layer and the second absorbent layer constituting the above-described absorber is not particularly limited as long as it can absorb and retain excretory fluid such as urine. Any absorbent member known in the art can be used. As such an absorbent member, for example, an absorbent core made of an arbitrary absorbent material covered with a core wrap sheet such as a hydrophilic tissue can be used. Furthermore, as an absorptive material which comprises the above-mentioned absorption core, a hydrophilic fiber, a superabsorbent polymer, etc. can be used, for example, More specifically, cellulose type, such as a pulverized pulp, cotton, rayon, acetate, etc. Fiber: Granules made of a superabsorbent polymer such as sodium acrylate copolymer can be used. These absorptive materials may be used alone or in combination of two or more absorptive materials. In addition, the 1st absorption layer and the 2nd absorption layer may use the absorbent member of the same structure, or may use the absorbent member of a different structure.

Furthermore, the second absorbent layer 21B also, as shown in FIGS. 1-2, the through hole 21A _S and the thickness direction T of the first absorbent layer 21A with a center in the width direction W of the crotch region _{A C} the overlapping position, and a through hole 21B _S to have a smaller dimensions than the through-hole 21A _S in a plan view, through the second absorption layer 21B in the thickness direction T. The through holes 21A _S and the through holes 21B _S communicate with each other in the thickness direction T, and penetrate the absorber 21 in the thickness direction T as a whole, and the opening area in the thickness direction T is stepwise. Different through holes are formed. When the absorber has such a through hole, absorption in the thickness direction T of the excretory fluid can be promoted, and thus more excellent absorption performance (particularly, absorption rate) can be exhibited.

  In the urine collecting pad 1 of the present embodiment, the absorbent body 21 does not need to be configured by two absorbent layers as in the above-described embodiment, and the absorbent body 21 has an absorbent member having a single-layer structure. Even if comprised, it may be comprised by the absorptive member which has a multilayer structure of three or more layers. The basis weight, thickness, and the like of the absorbent member that can be used as the absorbent layer constituting the absorbent body 21 are various characteristics that the absorbent member can function as the absorbent body 21 of the urine absorption pad 1 (for example, absorbency, flexibility, etc.). ), Any basis weight, thickness, etc. can be adopted.
