[Configuration of Absorbent Article 1]
First, the structure of the absorbent article 1 in the embodiment of the present invention will be described. In the following description of the absorbent article 1, in a state where the absorbent article 1 is deployed, the side located on the abdomen side of the human body (wearer) when worn is the front side, the side located on the back side is the rear side, The side in contact with the wearer is defined as the upper side, the side opposite to the side in contact with the wearer is defined as the lower side, and the direction orthogonal to both the front-rear direction and the vertical direction is defined as the left-right direction (width direction).
The front-rear direction is the X direction, the left-right direction is the Y direction, and the up-down direction is the Z direction.

  The absorbent article 1 is, for example, a urine picking pad for night or for a long time, and is used by being detachably attached to an outer body (not shown) attached to a human body such as a diaper, a diaper cover, and pants. The

As shown in FIGS. 1-4, the absorbent article 1 is formed so that a wearer's crotch may be covered from an abdominal side to a back side at the time of wearing.
Specifically, one end (front end) of the absorbent article 1 forms the abdomen side 11 located on the wearer's abdomen when worn, and the other end (rear end) is worn when worn. The back side part 12 located on the back side of the wearer is formed, and the crotch part 13 located between the abdomen side part 11 and the back side part 12 is located between the crotch of the wearer.
The dorsal side portion 12 may be formed so that the length in the front-rear direction is longer than the ventral side portion 11. Thereby, a wearer's back side can be widely covered by the back side part 12. FIG.
Further, both edge portions of the crotch portion 13 form two leg surrounding portions 14 and 14 located around the wearer's leg when worn from the abdominal side portion 11 to the back side portion 12. It is preferable that the leg periphery parts 14 and 14 are each provided with elastic members for flat gathers such as rubber thread. Thereby, since it fits elastically around a wearer's leg, while being able to suppress side leakage, it is easy to follow a wearer's body movement, and the absorptive article 1 becomes difficult to shift.

  The absorbent article 1 includes a liquid-permeable surface sheet 20 provided on the contact surface side (upper side) with the wearer when worn, and a back sheet provided on the side opposite to the contact surface with the wearer (lower side) when worn. 30, a back sheet 40 made of a non-woven fabric provided on the outer side opposite to the contact surface with the wearer when worn, an absorber 60 interposed between the top sheet 20 and the back sheet 30, and an absorber The absorbent sheet 70 provided on the lower surface of the sheet 60 and the widthwise side edges (left edge and right edge) of the absorbent body 60 on the surface sheet 20 side are provided along the longitudinal direction of the absorbent article 1.

That is, the length in the front-rear direction of the absorbent sheet 70 has at least the length in the front-rear direction of the hollow portion 601, and the length in the left-right direction is substantially the same as the left-right direction of the top sheet 20 and the back sheet 30. Have

  FIG. 6 shows a plan view of the absorbent sheet 70. In FIG. 7, the VV sectional drawing of the absorption sheet 70 is shown. FIG. 6 is a perspective view. As shown in FIGS. 6 and 7, the absorbent sheet 70 includes a top sheet 71, a bottom sheet 72, and an absorbent material (hereinafter referred to as a polymer) 73 held between the sheets 71 and 72. . The upper surface sheet 71 is a sheet having liquid permeability, such as a nonwoven fabric. The lower surface sheet 72 is preferably a liquid-impermeable sheet such as a poly sheet, but is not limited thereto. The polymer 73 is a granular absorbent material that swells by absorbing moisture, and is, for example, the above-described superabsorbent resin.

  The upper surface sheet 71 and the lower surface sheet 72 are joined to each other at a position indicated by a thick line (white line) in FIG. 6 by, for example, a hot melt adhesive, a heat seal, an ultrasonic seal, or the like. A portion where the upper sheet 71 and the lower sheet 72 are bonded to each other is referred to as a bonded portion. In the absorbent sheet 70, a plurality of joint portions 75 extending in the width direction of the absorbent sheet 70 are provided in a part of the absorbent body 60 corresponding to the regions interposed between the left and right hollow parts 601. It is provided at every interval. The polymer 73 is held in a cylindrical space S surrounded by the adjacent joint portions 75 and the upper surface sheet 71 and the lower surface sheet 72 therebetween in a state where movement is restricted in a dry state. For example, the polymer 73 is fixed to at least one of the upper sheet 71 or the lower sheet 72 by an adhesive member such as a water-soluble adhesive.

The fixing member 90 is an adhesive tape that plays a role in adhering and fixing the absorbent article 1 to the exterior body, and the adhesive portion is exposed when the release paper is peeled off.

For example, the fixing member 90 may be a hook-and-loop fastener, but is as soft as possible. Is more suitable for following the movement of the wearer's body, and is more preferable.

[Operation of Absorbing Sheet 70]
Next, the operation of the absorbent sheet 70 provided in the absorbent article 1 will be described. In the following description, upper (upper) and lower (lower) refer to upper (upper) and lower (lower) in the direction of gravity.

FIG. 8 schematically shows the upper surface of the absorbent sheet 70 after urination. FIG. 9 schematically shows a VV cross section of the absorbent sheet 70 after urination. FIG. 8 is a perspective view.
For example, when urination is performed in a horizontal posture with the left side down, the urinated urine flows downward from the urination position. The polymer 73 located below the urination position of the absorbent sheet 70 (region A2 in FIG. 8) is released from adhesion with the upper surface sheet 71 or the lower surface sheet 72 (or both when bonded to both) due to moisture of urine. In addition, as shown in FIG. 8 and FIG. 9, the urine moisture is absorbed and swollen in the cylindrical space S, and the swollen absorbent materials are repelled and pressed against each other, thereby following the flow of urine. It is pushed out in the longitudinal direction of the space S and moves to a region corresponding to the lower punched portion 601 (left side). As a result, the polymer 73 is filled in the region corresponding to the lower hollow portion 601 and a new absorption region is formed, so that the hollow portion 601 that did not have an absorption function also has absorbency, Side leakage can be effectively suppressed.

  Further, as shown in FIG. 9, since the urine-absorbing polymer 73 swells, a groove is formed in the joint 75, so that urine can easily flow along the groove and diffuse. .

  In addition, since the polymer 73 located on the upper side (region A1) at the time of urination remains unused, it can be used when the posture is changed, and the polymer 73 can be effectively used to reduce waste. it can.

  As described above, in the absorbent article 1, the absorbent sheet 70 is provided on the lower surface of the absorbent body 60. The absorbent sheet 70 includes a liquid-permeable upper surface sheet 71, a lower surface sheet 72, and a granular polymer 73 that swells by absorbing moisture. The top sheet 71 and the bottom sheet 72 are joined together by a plurality of joints 75 that are parallel to each other. The movement of the polymer 73 in the cylindrical space S surrounded by the adjacent joint 75 and the upper surface sheet 71 and the lower surface sheet 72 is restricted in a dry state, and the restriction of the movement is released when moisture is absorbed. Is held by.

  Therefore, when urination is performed, the polymer 73 on the lower side (region A2 in FIG. 8) than the urination position of the absorbent sheet 70 is adhered to the upper surface sheet 71 or the lower surface sheet 72 (both of them by moisture of urine). Are released from each other), absorbs urine moisture and swells in the cylindrical space S, and the swollen absorbent materials repel each other and push each other in the longitudinal direction of the space S. Moving. As a result, a new absorption region can be formed in the region where the polymer 73 does not exist, so that the absorption performance can be provided, and urine leakage can be effectively suppressed. Moreover, the area | region which arrange | positions the polymer 73 previously can be restrict | limited, and the waste of the polymer 73 can be suppressed. Since the polymer 73 located on the upper side at the time of urination remains unused, it can be used when the posture is changed, and the polymer 73 can be effectively used to reduce waste. Furthermore, since the polymer 73 that has absorbed urine swells, a groove is formed in the portion of the joint 75, so that urine can easily flow along the groove and diffuse.

  In particular, the absorbent body 60 of the absorbent article 1 has a hollow portion 601 on both sides in the width direction of the crotch portion, and the absorbent sheet 70 is provided so as to cover at least the hollow portion 601 and a plurality of joint portions 75. Is formed in a portion corresponding to a region interposed between the hollowed portions 601 of the absorbent body 60 such that the longitudinal direction thereof is the width direction of the absorbent article 1. Therefore, when urination is performed in a horizontal posture while maintaining a good feeling of wearing around the legs, the polymer 73 is filled in the region corresponding to the hollowed-out portion 601 on the lower side, so that the absorption function It is possible to make the punched-out portion 601 that has not had an absorptivity and prevent side leakage.

  For example, the polymer 73 that is an absorbent material is fixed to at least one of the top sheet 71 or the bottom sheet 72 by a water-soluble adhesive member and held in the space S, thereby restricting movement in a dry state, The polymer 73 can be held in a state where the restriction of movement is released during absorption.

  In addition, this invention is not restricted to the thing of above-described embodiment, In the range which does not deviate from the summary, it can change suitably.

  For example, in the above-described embodiment, the case where the absorbent sheet 70 is provided on the lower surface of the fit-cut absorbent body 60 is described, but the absorbent sheet 70 may be provided on the lower surface of the rectangular absorbent body 60. For example, if an absorbent material such as a polymer is arranged around the legs of the absorbent body 60 in advance, it is wasteful when the posture is not changed. However, by providing the absorbent sheet 70, the absorbent material can be absorbed by the absorbent body 60. Even if it is not arranged around the leg, sufficient absorption performance can be provided around the leg, there is no waste of the absorbent material, and leakage of urine can be suppressed.

  Moreover, in the said embodiment, taking the case where the longitudinal direction (namely, longitudinal direction of the junction part 75) of the cylindrical space S in which the polymer 73 of the absorption sheet 70 is hold | maintained is a width direction of the absorbent article 1. Although described, this direction is not particularly limited. For example, in the case of a wearer with a great posture on the back, by using the absorbent sheet 70 in which the longitudinal direction of the cylindrical space S (that is, the longitudinal direction of the joint portion 75) is the longitudinal direction of the absorbent article 1, The polymer 73 can be moved in the direction of the portion 12, and urine leakage can be effectively suppressed. As described above, the absorbent sheet 70 can be made absorbent by moving the polymer 73 in an arbitrary direction to be moved according to the longitudinal direction of the cylindrical space S (that is, the longitudinal direction of the joint portion 75).

  In the above embodiment, the polymer 73 is adhered to at least one of the upper sheet 71 or the lower sheet 72 with a water-soluble adhesive member, thereby suppressing the movement of the polymer 73 in a dry state before urination. It is not limited to this. For example, as shown by black lines in FIG. 10, the upper sheet 71 and the lower sheet 72 are bonded by an adhesive member at a plurality of positions in the longitudinal direction of the cylindrical space S, and are separated by the bonding. Alternatively, the movement of the polymer 73 in a dry state may be regulated by holding the polymer 73 in each space. As the adhesive member, an adhesive member having such a weak adhesive strength that the adhesive is peeled off by swelling of the polymer 73 due to moisture absorption is used. In this way, the movement of the polymer 73 in the longitudinal direction of the cylindrical space S (that is, the direction parallel to the joint 75) in the dry state before urination can be restricted, and the movement is restricted during urination. Can be released.

  Moreover, in the said embodiment, in order to make the space S into a cylinder shape and to make it easy for the polymer 73 to move in a fixed direction at the time of moisture absorption, the plurality of joint portions 15 are parallel to each other, but this is not limitative. For example, the adjacent joint portions 15 may have a square shape.

  Moreover, in the said embodiment, although the absorber 60 was made into one layer and it demonstrated as providing the absorber sheet 70 in the lower surface of the absorber 60, the absorber 60 may be a multiple layer. In this case, the absorbent sheet 70 may be provided between the layers of the absorber 60. Moreover, it is good also as providing the absorption sheet 70 on the upper surface of the absorber 60. FIG.

  Moreover, in the said embodiment, although the case where the number of the space S is five is illustrated, the number of the space S is not specifically limited.

  Moreover, although the urine-absorbing pad is exemplified and described as the absorbent article, the absorbent article may be, for example, a paper diaper or a sanitary pad.

  In addition, the detailed configuration of the absorbent article 1 can be changed as appropriate without departing from the spirit of the present invention.
