The absorbent pad 10 has a front-rear direction, a width direction, and a thickness direction that intersect each other. In the front-rear direction, the front side is the side that serves as the wearer's ventral side, and the rear side is the side that serves as the wearer's dorsal side. In addition, when worn, the side that becomes the wearer's torso side is the upper side, and the wearer's crotch side is the lower side. Note that the vertical direction is a direction along the front-rear direction. Thickness direction WHEREIN: Let the side which touches a wearer's body be a skin side, and let the other side be a non-skin side. The center line CC in FIG. 3 etc. indicates the center in the width direction, and the center line CL indicates the center in the front-rear direction. Of the absorbent pad 10, the portion on the front side of the central line CL in the front-rear direction is also called a front side portion 10F, and the portion on the rear side of the center line CL is also called a rear side portion 10R.

The "unfolded state" of the absorbent pad 10 refers to a state in which the absorbent pad 10 is fully unfolded, and the "stretched state" refers to a state in which the absorbent pad 10 is stretched without wrinkles. 10 (for example, a side seat 50 to be described later) is in a state of being stretched to a length that matches or is close to the dimension of the individual member.

As shown in FIGS. 3 to 5, the absorbent pad 10 has a substantially rectangular shape in plan view, and has a substantially symmetrical shape about the center line CC in the width direction. has a substantially symmetrical shape with respect to the center line CL. The absorbent pad 10 has a skin-side sheet 20 , a non-skin-side sheet 22 , an absorbent body 30 , a side sheet 50 , leg elastic members 54 , and hook portions 25 .

The skin-side sheet 20 is a liquid-permeable sheet member, and for example, a hydrophilic air-through nonwoven fabric, a spunbond nonwoven fabric, or the like is used. The skin-side sheet 20 covers the entire skin-side surface of the absorbent body 30 . The non-skin side sheet 22 is a liquid-impermeable sheet member, and for example, an appropriate resin film such as polyethylene (PE) is used. The non-skin side sheet 22 covers the entire non-skin side of the absorbent body 30 .

Moreover, the hook portion 25 can be used not only for temporarily fixing the absorbent pad 10 to the diaper 1 but also for temporarily fixing it to the skin side of clothing such as underwear.

<<About wearing condition>>
In general, when the central portion of the absorbent article in the worn state in the width direction protrudes toward the skin side, the absorbent article (absorbent core) is brought into contact with the wearer's excretory opening and quickly absorbs excrement. It is known that it is possible to reduce the discomfort during wearing. However, when a conventional absorbent article is applied with force from the outer side to the inner side in the width direction by the legs of the wearer when worn and in the state of being worn, the absorbent article (absorbent core) does not conform to the wearer's intention. There was a risk of deformation to the opposite shape. In particular, the absorbent core is a thick member in the absorbent article and has high rigidity. There is a fear that it will be difficult to correct, and that the wearer will continue to feel discomfort and discomfort.

On the other hand, the absorbent pad 10 of this embodiment makes it easy to deform the absorbent core 32 (absorbent pad 10) so as to bring it closer to the wearer's excretory opening. Helps reduce discomfort and discomfort. The absorbent core 32 will be described below.

<<Absorptive core 32>>
FIG. 6 is a schematic plan view of the absorbent core 32 of FIG. 3 as seen from the skin side. As shown in FIG. 6, the absorbent core 32 has a substantially hourglass shape in plan view, has a shape substantially symmetrical about the center line CC in the width direction, and is substantially symmetrical about the center line CL in the front-rear direction. shape. The absorbent core 32 also has a narrow portion M whose length in the width direction is shorter than the front and rear ends in the front-rear direction. The narrow portion M is positioned at the wearer's crotch when worn. Specifically, the narrow portion M extends from the front and rear ends in the front-rear direction to the central portion in the front-rear direction so that the length in the width direction is the shortest at the central portion in the front-rear direction of the absorbent core 32 . Also, it is a constricted portion that curves inward in the width direction. The “narrow portion M” is a region having a shorter width in the width direction than the longest portion in the width direction of the absorbent core 32, and the center (the center line CL) in the front-rear direction. The part that contains The “front end portion in the front-rear direction” is a portion of the front side portion 10</b>F that has the longest portion in the width direction and is on the front side of the narrow portion M. The “end portion on the rear side in the front-rear direction” is a portion that has the longest portion in the width direction of the rear portion 10R and is on the rear side of the narrow portion M. As shown in FIG. As shown in FIG. 6, the widthwise length of the front end in the front-rear direction and the widthwise length of the rear end in the front-rear direction are ), and the length in the width direction of the narrow portion M is the width of the front end in the front-rear direction and the width of the rear end in the front-rear direction. less than the direction length. As shown in FIG. 6, the front end of the narrow portion M is referred to as a front end Mf, and the rear end of the narrow portion M is referred to as a rear end Mr. As shown in FIG. The front side of the narrow portion M (front end Mf) is referred to as a front portion F, and the rear side of the narrow portion M (rear side end Mr) is referred to as a rear portion R. The front portion F is the front end in the front-rear direction, and the rear portion R is also the rear end in the front-rear direction.

The length of the narrow portion M in the front-rear direction is preferably 125 mm or more. By doing so, when worn, first, the absorbent core 32 is prevented from being deformed starting from the slit 40 before being deformed by the folding guide portion 43, and the absorbent core 32 is formed into a shape contrary to the wearer's intention. The fear of deformation can be reduced.

The absorbent core 32 has a pair of folding guides 43 . A front side folding guiding portion (one side folding guiding portion) 43fa and a front side folding guiding portion (one side folding guiding portion) 43fb are provided as the folding guiding portion 43 on the front side of the absorbent core 32 in the front-rear direction, that is, the front side portion 10F. , the rear side of the absorbent core 32 in the front-rear direction, that is, the rear side portion 10R, as the folding guide portion 43, includes a rear side fold guide portion (other side fold guide portion) 43ra and a rear side fold guide portion (other side fold guide portion) 43ra. part) 43rb. Forming the folding guides 43 by pressing increases the density of the liquid-absorbent fibers and increases the rigidity of the area in comparison with the region where the folding guides 43 are not provided. In addition, it is possible to form the folding guide portion 43 by a simple process. Each folding guide portion 43 of the present embodiment is a compressed portion obtained by compressing the absorbent core 32 in the thickness direction from the non-skin side toward the skin side. Each folding guide portion 43 formed by pressing may be a pressed portion obtained by pressing the absorbent core 32 in the thickness direction from the skin side toward the non-skin side. By compressing the absorbent core 32 from the non-skin side toward the skin side, the folding guide portions 43 can be folded more easily so as to protrude from the skin side toward the non-skin side.

The absorbent core 32 has a pair of slits 40 . The absorbent core 32 has slits 40fa and 40fb as the slits 40 in the front portion 10F, and slits 40ra and 40rb as the slits 40 in the rear portion 10R. Each slit 40 is a penetrating portion penetrating through the absorbent core 32 in the thickness direction. The slits 40 are formed not only in areas where liquid-absorbent fibers such as pulp and liquid-absorbent particles such as superabsorbent polymers (SAP) are completely absent, but also in areas where there are some liquid-absorbent fibers and liquid-absorbent particles such as superabsorbent polymers (SAP). may be present. The slit 40 is a portion in which liquid-absorbent fibers and liquid-absorbent granules are clearly less than the surrounding area, and the rigidity is lower than the surrounding area.

The slit 40 of the present embodiment is continuous with the slit 40fa on one side in the width direction (left side when viewed from the skin side surface) and the slit ra, and the slit 40fb on the other side in the width direction (right side when viewed from the skin side surface). The slits 40rb are continuous, and the continuous slits 40fa, 40ra and continuous slits 40fb, 40rb are provided so as to straddle the center in the front-rear direction. The slit 40fa of the front side portion 10F and the slit ra of the rear portion R are continuous, and the slit 40fb of the front side portion 10F and the slit 40rb of the rear portion R are continuous. , 40rb is made easy to form a convex shape toward the skin side.

The width (thickness) of the slit 40 is preferably 3 mm or more, and the length of the entire slit 40 in the front-rear direction is preferably 80 mm or more. By doing so, the absorbent core 32 can be easily deformed from the slit 40 as a starting point, and the excrement absorbed by the absorbent core 32 can be easily diffused in the front-rear direction by the slit 40 .

Since the configuration of the front side portion 10F is the same as the configuration of the rear side portion 10R, the configuration of the front side portion 10F will be described below.

The folding guide portion 43 is a portion for guiding deformation due to folding of the absorbent core 32, and is a portion having a rigidity different from that of adjacent regions. In the present embodiment, the folding guide portion 43 has higher rigidity than the adjacent regions because the absorbent core 32 is compressed in the thickness direction. Therefore, the folding guide portion 43 is a portion that tends to become a starting point of deformation of the absorbent core 32 .

The front folding guide portion 43fa is inclined from the front side to the rear side in the front-rear direction and from the center portion in the width direction to the outside. Specifically, as shown in FIG. 6, the front folding guide portion 43fa is a region having a substantially linear predetermined width (thickness) that slopes diagonally downward to the left from the center in the width direction. Similarly, the front folding guide portion 43fb is inclined from the front side to the rear side in the front-rear direction and from the central portion in the width direction toward the other outside. Specifically, the front-side folding guide portion 43fb is a region having a substantially linear predetermined width (thickness) that is inclined downward to the right from the central portion in the width direction.

The slits 40fa and 40fb extend in the front-rear direction and are provided on both sides in the width direction. The slits 40fa and 40fb of the present embodiment include a straight portion on the front side in the front-rear direction of the front side portion 10F, and a curved portion curved outward in the width direction on the rear side in the front-rear direction. Since the slits 40fa and 40fb are portions through which the absorbent core 32 penetrates in the thickness direction, the rigidity is lower than that of the adjacent regions. Therefore, the slits 40fa and 40fb are portions that tend to become deformation starting points of the absorbent core 32 .

In the front-rear direction, the slit 40 is positioned rearward of the folding guide portion 43, the slit 40 has a portion overlapping the narrow portion M in the front-rear direction, and the front end of the slit 40 overlaps the narrow portion M. Positioning the absorbent core 32 on the rear side of the front end makes it easier to deform the absorbent core 32 when worn as shown in FIG. FIG. 7 is a schematic perspective view explaining deformation of the absorbent core 32 when the absorbent pad 10 is worn.

In the present embodiment, as shown in FIG. 6, the slits 40fa and 40fb are located on the rear side of the front folding guide portions 43fa and 43fb in the front-rear direction. That is, the portions of the compressed portion on the front side of the slits 40fa and 40fb are referred to as front-side folding guide portions 43fa and 43fb. In addition, since the slits 40fa and 40fb are provided in the narrow width portion M over the entire area, the entire area of the slits 40fa and 40fb overlaps the narrow width portion M in the front-rear direction. is located on the rear side of the front end Mf of the narrow portion M.

Deformation of the absorbent core 32 when wearing the absorbent pad 10 will be described. The deformation of the absorbent core 32 when the absorbent pad 10 is worn is mainly due to the force applied from the wearer's legs to the absorbent core 32 (absorbent pad 10) or from the outside of the diaper 1, clothes, or the like. It is likely caused by forces applied to the absorbent core 32 (absorbent pad 10).

First, when wearing the absorbent pad 10, when the absorbent pad 10 is attached to the inner side of the diaper 1, the front side portion 10F of the absorbent pad 10 is bent by the ring shape that constitutes the waist portion of the diaper 1 (clothes). The front end portion and the rear end portion of the rear side portion 10R are deformed so as to stand up toward the skin side, and the front side folding guide portions 43fa and 43fb are easily bent toward the non-skin side.

Subsequently, when the diaper 1 ( FIG. 1 ) with the absorbent pad 10 attached is pulled up from the base of the leg toward the crotch, the slit of the absorbent core 32 is formed by providing the absorbent core 32 with the narrow portion M. This reduces the risk of the wearer's legs coming into contact with the central portion of the absorbent core 32 in the front-rear direction before the wearer's legs come into contact with the portions on the front side of 40fa and 40fb. When a force is applied from the outer side toward the inner side in the width direction to the region on the front side of the slits 40fa and 40fb of the absorbent core 32, the front fold guide portions 43fa and 43fb located on the front side of the slits 40fa and 40fb are pushed toward the non-skin side. It becomes easy to deform|transform so that it may be bend|folded toward it, and front side folding guide part 43fa, 43fb becomes easy to bend|fold toward a non-skin side.

Furthermore, when the absorbent pad 10 (diaper 1) is pulled up to the crotch area of the wearer and applied to the narrow portion M provided with the slits 40fa and 40fb by the wearer's legs from the outside in the left-right direction, the narrow portion M The slits 40fa and 40fb overlapping in the front-rear direction are easily deformed. When the narrow portion M is applied from the outside in the left-right direction, an external force such as force from the diaper 1 or force from the wearer's legs (hereinafter simply referred to as "external force") is applied to the non-skin side. Due to the deformation of the front side fold guide portions 43fa and 43fb that are bent inward, external force is transmitted from the front side fold guide portions 43fa and 43fb to the slits 40fa and 40fb, and the slits 40fa and 40fb are easily deformed toward the non-skin side. Become. That is, the slits 40fa and 40fb located behind the front folding guide portions 43fa and 43fb that are bent toward the non-skin side are less likely to be bent toward the skin side, and the slits 40fa and 40fb are located on the non-skin side.

By bending the slits 40fa and 40fb toward the non-skin side, as shown in FIG. 7, a region X between the slits 40fa and 40fb in the front-rear direction can be made convex toward the skin side. By making the region X convex toward the skin side, the wearer's excretory opening can be brought closer to the wearer's excretion opening, and the excretory material can be easily fitted to the excretory opening, thereby quickly absorbing excrement. As a result, discomfort felt by the wearer due to excrement remaining on the surface of the absorbent pad 10 can be reduced.

FIG. 8A is a diagram illustrating the slit 40 and the folding guide portion 43 of the first embodiment. As shown in FIG. 8A, it is preferable to have a matching point G where at least a portion of the front folding guide portions 43fa and 43fb and the edges of the slits 40fa and 40fb match. The coincidence point G makes it easier to transmit an external force from the front fold guide portion 43fa to the slit 40fa, and to easily transmit an external force from the front fold guide portion 43fb to the slit 40fb. Therefore, the slits 40fa and 40fb are easily guided to be folded toward the non-skin side, and the region X between the slits 40fa and 40fb is easily protruded toward the skin side. Note that the compressing portions that constitute the front folding guide portions 43fa and 43fb may be provided behind the front ends of the slits 40fa and 40fb. However, the folding guide portion 43 in this embodiment refers to a portion on the front side of the matching point with the slits 40fa and 40fb.

Moreover, as described above, the absorbent pad 10 has the hook portion 25 on the non-skin side. As shown in FIG. 3, it is preferable that a matching point G is provided inside both ends of the hook portion 25 in the width direction, where the edges of the front folding guide portions 43fa and 43fb and the slits 40fa and 40fb are aligned. In the absorbent pad 10 , the inner side of the hook portions 25 in the width direction is fixed to the diaper 1 more than the outer side of the hook portions 25 in the width direction. Therefore, by providing the matching point G inside both ends of the hook portion 25 in the width direction, external force can be easily transmitted to the slits 40fa and 40fb via the front folding guide portions 43fa and 43fb. can be easily bent toward the non-skin side, and the region X between the slits 40fa and 40fb can be easily protruded toward the skin side.

As shown in FIGS. 6 and 8A, it is preferable that the front folding guide portion 43fa and the front folding guide portion 43fb are continuous at the front end. By connecting the front fold guide portion 43fa and the front fold guide portion 43fb, an external force such as force from the diaper 1 or the legs of the wearer is transmitted through the front fold guide portion 43fa and the front fold guide portion 43fb to the slit 40fa and the slit. 40fb, the slits 40fa and 40fb are bent toward the non-skin side, and the area X between the slits 40fa and 40fb is easily protruded toward the skin side.

It is preferable to have a portion where the narrow portion M overlaps the front side folding guide portions 43fa and 43fb in the front-rear direction. More preferably, the longitudinal length of the portion where the narrow portion M overlaps the front folding guides 43fa and 43fb is at least half the length of the front folding guides 43fa and 43fb. As shown in FIG. 6 and the like, in this embodiment, the front side folding guide portions 43fa and 43fb are entirely overlapped with the narrow portion M in the front-rear direction. The narrow portion M overlaps the front fold guide portions 43fa and 43fb in the front-rear direction, so that when the absorbent pad 10 is put on, the slits 40fa and 40fb are the starting points before the front fold guide portions 43fa and 43fb are bent. First, it becomes easier to induce deformation of the absorbent core 32 starting from the front folding guide portions 43fa and 43fb. 40fb is guided to be bent toward the non-skin side, and the region X sandwiched between the slits 40fa and 40fb is easily formed into a convex shape toward the skin side.

The length between the front ends of the front folding guide portions 43fa and 43fb and the front end Mf of the narrow portion M in the front-rear direction is preferably 30 mm or less. By doing so, it becomes easier to apply an external force to the deformation of the front fold guide portions 43fa and 43fb first, and the deformation of the front fold guide portions 43fa and 43fb causes the slits 40fa and 40fb to bend toward the non-skin side. becomes easier to induce

As shown in FIG. 6, the longitudinal length L40f of the slits 40fa and 40fb is preferably longer than the longitudinal length L43f of the front folding guide portions 43fa and 43fb (L40f>L43f). Since the slits 40fa and 40fb extend in the front-rear direction, the absorbent core 32 absorbs more water than when the length L43f in the front-rear direction of the front folding guide portions 43fa and 43fb is longer than the length L40f in the front-rear direction of the slits 40fa and 40fb. The discharged excrement is easily diffused in the front-rear direction of the absorbent core 32, and the excrement is easily absorbed in a wide range of the absorbent core 32. - 特許庁

<<<absorbent pad 100>>>
FIG. 9 is a schematic plan view of the absorbent pad 100 in an unfolded and stretched state, viewed from the skin side. FIG. 10 is a diagram illustrating the front portion 10F of the absorbent core 320 of FIG. Hereinafter, with regard to the absorbent pad 100 of the second embodiment, mainly different parts from the first embodiment will be described. A detailed description of the configuration is omitted. Also, some of the configurations of the absorbent pad 10 of the first embodiment can also be applied to the absorbent pad 100 of the second embodiment.

As in the first embodiment, the absorbent pad 100 of the second embodiment has a skin-side sheet 20, a non-skin-side sheet 22, an absorber 30, side sheets 50, leg elastic members 54, and hook portions 25. Further, as in the first embodiment, the absorbent core 320 includes a narrow portion M and a pair of slits 40, and a folding guide portion 43 having a predetermined width (thickness), which is composed of a plurality of compressed portions 45. have.

The absorptive core 32 of the second embodiment is provided with a substantially grid-like compressed portion 45 over substantially the entire region excluding the central region Z of the central portion in the front-rear direction and the central portion in the width direction. The compressed portion 45 has discontinuous portions that are not continuous in the width direction and the front-rear direction. The region provided with the pressing portion 45 has high rigidity, and a difference in rigidity occurs between the region provided with the pressing portion 45 and the adjacent region not provided with the pressing portion 45 . In the second embodiment, the pressing portion 45 is not provided in the central region Z, and the pressing portion 45 is not provided in the region between the pair of slits 40 in the width direction of the absorbent core 32 .

The folding guide portion 43 of the second embodiment is a portion having different rigidity between the pressing portions 45 adjacent to each other and an area where the pressing portions 45 are not provided. and the center region Z are different in rigidity. The absorbent core 32 is compressed in the thickness direction to be stiffer than the adjacent regions. In FIG. 10, the folding guide portion 43 of the second embodiment is a pressing portion 45 provided in a region surrounded by a virtual line 43w. As shown in FIG. 10, the portion 43) is inclined from the front side to the rear side and from the center portion in the width direction to the outside. Therefore, the folding guide portion 43 transmits external force to the slits 40fa and 40fb, guides the slits 40fa and 40fb to be bent toward the non-skin side, and stretches the region X between the slits 40fa and 40fb to the skin side. It becomes easier to protrude sideways, and it becomes easier to deform the absorbent core 32 into a shape as shown in FIG. 7 .

In addition, the absorbent core 32 of the second embodiment has a substantially grid-like compressed portion 45 in substantially the entire area except the central region Z, and high-rigidity portions are provided intermittently, thereby improving the absorbency. The thickness of the core 32 is thin (the length in the thickness direction is short), and this portion is likely to become a starting point of bending. In other words, the regions other than the central region Z of the absorbent core 32 of the second embodiment can easily deform the absorbent core 32 due to the pair of slits 40 and the compressed portion 45 . This makes it easier to transmit external force during wearing to the slits 40fa and 40fb via the folding guide portion 43, making it easier to guide the slits 40fa and 40fb to bend toward the non-skin side. And it becomes easy to make the center area|region Z between slit 40fa and slit 40fb protrude toward the skin side. Furthermore, since the area between the slits 40fa and 40fb that protrude toward the skin side is also the central region Z in which the compressed portion 45 is not provided, the central region Z can be flattened to allow the wearer to excrete. Since it becomes easier to bring it closer to the mouth, it improves the feel of the wearer's excretion port on the skin, and also makes it easier to quickly absorb excrement, so that discomfort and discomfort during wearing can be reduced.

In addition, in the absorbent core 32 of 2nd Embodiment, it is not necessarily restricted to the structure which does not necessarily provide the pressing part 45 in the center area|region Z. FIG. For example, between the pair of slits 40fa and 40fb, a pressing portion similar to the pressing portion 45 provided in the front portion F or the rear portion R may be provided. Even when a compressed portion is provided between a pair of slits 40fa and 40fb, a portion having a different rigidity between the compressed portion 45 and a region adjacent to the compressed portion where no compressed portion is provided is provided. Thus, the folding guide portion 43 can guide the slits 40fa and 40fb to be bent toward the non-skin side, making it easier to project the space between the slits 40fa and 40fb toward the skin side. In addition, by providing the compressed portion in a wider range of the absorbent core 32, the thickness of the absorbent core 32 can be reduced (the length in the thickness direction can be shortened), and the entire absorbent core 32 can be Since the rigidity is increased, the deformation of the absorbent core 32 is facilitated.
