(1st leakage suppression unit)
The first leak suppressing portion 20 is provided on the surface sheet 11 side of the main body portion 10. The first leak suppressing portion 20 is a strip-shaped member extending along the longitudinal direction X of the main body portion 10.

The first leakage suppressing portion 20 is made of a hydrophobic non-woven fabric and has a first suppressing portion main body 200 extending in the longitudinal direction X and an elastic member 201 attached along the longitudinal direction of the first suppressing portion main body 200. .. The non-woven fabric that is the material of the first leak suppressing portion 20 may be water-repellent.

The first restraining portion main body 200 is joined to the main body portion 10 (front surface sheet 11 and back surface layer 12) along the longitudinal direction X at the end portion of the head side A in the width direction Y of the main body portion 10. The joining method may be fusion or adhesion.

In the following description, the "edge" refers to a region including a certain range including the edge of the article.
Further, the "edge" refers to the edge of the article. The same applies to "one end" and "the other end".

The first leakage suppressing portion 20 has a first joining portion 20X which is a region joined to the main body portion 10 and a first standing portion 20Y which is a region not joined to the main body portion 10.

The first joint portion 20X is an end portion of the head side A in the width direction Y of the first leakage suppression portion 20, and is a region bonded to the main body portion 10 (front surface sheet 11 and back surface layer 12). The first joint portion 20X is provided along the longitudinal direction X at the end portion of the head side A of the first leakage suppression portion 20. The joining method may be fusion or adhesion.

The first standing portion 20Y is an end portion of the tail side B in the width direction Y of the first leakage suppressing portion 20, and is a region not joined to the main body portion 10. The first standing portion 20Y is provided along the longitudinal direction X at the end portion of the tail side B of the first leakage suppressing portion 20.

Further, as shown in FIG. 4, the first leakage suppressing portion 20 may be provided with a third joining portion 20Z to be joined to the surface sheet 11. In the present embodiment, the third joint portion 20Z is an end portion of the tail side B in the width direction Y of the first leak suppression portion 20, and is provided at both ends in the longitudinal direction X.

When the first leak suppressing portion 20 is joined to the surface sheet 11 at the third joining portion 20Z, the range of the first standing portion 20Y is the end portion of the tail side B in the width direction Y of the first leak suppressing portion 20. And, it refers to the region where the third joint portion 20Z is not provided.

In the first standing portion 20Y, the inner end portion of the first restraining portion main body 200 in the width direction Y is folded back along the longitudinal direction X while involving the elastic member 201. As shown in FIG. 2, the elastic member 201 is provided near the center of the main body portion 10 in the longitudinal direction X, and is partially fixed in a state of being extended in the longitudinal direction X at the time of manufacturing. The elastic member 201 is released from the force applied to extend the elastic member 201 during manufacturing, and contracts in the longitudinal direction X based on the contraction force (elastic force) of the elastic member 201.

The material of the elastic member 201 may be an elongated material that expands and contracts. Specifically, as the material of the elastic member 201, a thread-like rubber made of natural rubber, flat rubber or the like, or a thermoplastic elastomer such as urethane, ethylene-vinyl acetate copolymer (EVA) or PE can be used. As the thermoplastic elastomer, polybutadiene, polyisoprene, a styrene-butadiene copolymer, a styrene-isoprene copolymer, a polyurethane, an ethylene-vinyl acetate copolymer, an ethylene-α-olefin copolymer, or the like is molded into a thread shape. Examples thereof include those molded into a film and slit in a narrow width.

The folded band-shaped region, which is the inner end of the first restraining portion main body 200, is joined to the facing first suppressing portion main body 200. In the first standing portion 20Y, the portion where the first restraining portion main body 200 winds and joins the elastic member 201 constitutes the gather portion 25. The gather portion 25 has a structure known as a three-dimensional gather.

The region where the gathered portion 25 is formed is contracted with the contraction of the elastic member 201. Therefore, the first standing portion 20Y contracts in the longitudinal direction X of the first standing portion 20Y.

Further, the first leak suppressing portion 20 is joined to the nonwoven fabric 122 of the main body portion 10 in a state where the elastic member 181 is sandwiched between the ends of the head side A in the width direction Y of the first leak suppressing portion 20. .. The elastic member 181 is provided along the longitudinal direction X of the main body portion 10 and is fixed in a state of being extended in the longitudinal direction X. In the first leak suppressing portion 20, the portion sandwiching the elastic member 181 and being joined to the nonwoven fabric 122 of the main body portion 10 constitutes the first flap portion 18. The first flap portion 18 is located on the outermost side of the head side A in the width direction Y of the main body portion 10 and extends in the longitudinal direction X.

As the material of the elastic member 181, the same material as the material of the elastic member 201 can be used.

(Second leak suppression unit)
The second leakage suppressing portion 30 is provided on the surface sheet 11 side of the main body portion 10. The second leakage suppressing portion 30 is a strip-shaped member extending along the longitudinal direction X of the main body portion 10. Further, the width of the second leak suppressing portion 30 is narrower than the width of the first leak suppressing portion 20.

The second leakage suppressing portion 30 is made of a hydrophobic non-woven fabric and has a second suppressing portion main body 300 extending in the longitudinal direction X. The non-woven fabric that is the material of the second leakage suppressing portion 30 may be water-repellent.

The second leakage suppressing portion 30 has a second joining portion 30X which is a region joined to the main body portion 10 and a second standing portion 30Y which is a region not joined to the main body portion 10.

The second joint portion 30X is an end portion of the tail side B in the width direction Y of the second leakage suppression portion 30, and is a region bonded to the main body portion 10 (front surface sheet 11 and back surface layer 12). The second joint portion 30X is provided along the longitudinal direction X at the end portion of the tail side B of the second leakage suppression portion 30. The joining method may be fusion or adhesion.

The second standing portion 30Y is an end portion of the head side A in the width direction Y of the second leakage suppressing portion 30, and is a region not joined to the main body portion 10. The second standing portion 30Y is provided along the longitudinal direction X at the end portion of the head side A of the second leakage suppressing portion 30.

Unlike the first standing portion 20Y, the second standing portion 30Y does not have an elastic member that contracts the second standing portion 30Y in the longitudinal direction.

Both ends of the second upright portion 30Y in the longitudinal direction X may be weakly joined to the surface sheet 11. In FIG. 2, the weakly joined portion is indicated by the reference numeral HM.

The weak joint means that when the force applied to the joint portion is weak (for example, when a force sufficient to unfold the folded pet absorbent article 1 is indirectly transmitted to the joint portion), the joint state is It is maintained, but when a predetermined force or more is applied to the joint (for example, when the joint is in contact with the pet to be attached, the movement of the pet's body releases the joint to the joint. When a force in the direction is applied), it represents a joint with a strength enough to release the joint state.

Further, the second leak suppressing portion 30 is joined to the nonwoven fabric 122 of the main body portion 10 with the elastic member 191 sandwiched between the ends of the tail side B in the width direction Y of the second leak suppressing portion 30. .. The elastic member 191 is provided along the longitudinal direction X of the main body portion 10 and is fixed in a state of being extended in the longitudinal direction X. In the second leakage suppressing portion 30, the portion sandwiching the elastic member 191 and being joined to the nonwoven fabric 122 of the main body portion 10 constitutes the second flap portion 19. The second flap portion 19 is located on the outermost side of the main body portion 10 (front surface sheet 11 and back surface layer 12) in the width direction Y and extends in the longitudinal direction X.

As the material of the elastic member 191, the same material as the material of the elastic member 201 described above can be used.

As shown in FIG. 4, the detailed arrangement of each configuration in the absorbent article 1 is as follows. In the absorbent article 1, the central axis in the width direction Y is CL1, and the central axis in the longitudinal direction X is CL2. The central portion of the absorbent article 1 in the longitudinal direction X refers to the vicinity of the central axis CL2.

First, the absorbent article 1 has many configurations that are line-symmetrical with respect to the central axis CL1 in the width direction Y. The distance A3 from the central axis CL1 to the first joint portion 20X is equal to the distance B3 from the central axis CL1 to the second joint portion 30X. Further, the length A4 from the first joint portion 20X to the end 10x of the head side A in the width direction Y of the main body portion 10 is from the second joint portion 30X to the end 10y of the tail side B in the width direction Y of the main body portion 10. Is equal to the length B4.

As shown in FIG. 4, when measuring the distance from the first joint portion 20X, the end 20a of the first joint portion 20X is used as a reference. The end 20a has a region joined to the main body portion 10 (first joining portion 20X) and a region not joined to the main body portion 10 (first standing portion 20Y) in the width direction of the first leakage suppressing portion 20. It is a boundary formed between them.

Further, when measuring the distance to the second joint portion 30X, the end 30a of the second joint portion 30X is used as a reference. The end 30a has a region joined to the main body portion 10 (second joining portion 30X) and a region not joined to the main body portion 10 (second standing portion 30Y) in the width direction of the second leakage suppressing portion 30. It is a boundary formed between them.

Further, the absorber 13 is arranged line-symmetrically with respect to the central axis CL1 in the width direction Y of the main body portion 10. That is, the distances from both ends of the absorber 13 in the width direction to the central axis CL1 are equal (A5 = B5). Further, the distances from both ends of the absorber 13 in the longitudinal direction to the central axis CL2 are also the same (C1 = D1).

However, the first standing portion 20Y and the second standing portion 30Y are not line-symmetrical with respect to the central axis CL1. Specifically, in the central portion of the main body portion 10 in the longitudinal direction X, the distance A1 from the head side end of the absorber 13 in the width direction Y to the first joint portion 20X, and the distance A1 from the first joint portion 20X to the first standing portion 20Y. The sum of the distance A2 to the inner end 20b is the distance B1 from the tail side end to the second joint 30X in the width direction Y of the absorber 13 and the inner side of the second standing portion 30Y from the second joint 30X. It is longer than the sum of the distance to the end 30b and the distance B2. That is, the relational expression (A1 + A2)> (B1 + B2) holds.

In the absorbent article 1, the distance A1 is equal to the distance B1 and the distance A2 is longer than the distance B2 at the central portion of the main body 10 in the longitudinal direction X (A2> B2).

Further, in the absorbent article 1, in the central portion of the main body portion 10 in the longitudinal direction X, the distance A1 is shorter than the distance A2, and the inner end 20b of the first standing portion 20Y overlaps with the absorber 13 in a plan view. (A2> A1). Further, in the absorbent article 1, the distance B1 is longer than the distance B2, and the inner end 30b of the second standing portion 30Y does not overlap with the absorber 13 in a plan view (B1> B2).

At this time, at the central portion of the main body portion 10 in the longitudinal direction X, the distance A1 may be longer than the distance B1 (A1> B1). That is, the absorber 13 may be arranged in the main body portion 10 so as to be offset from the tail side B.

Further, in the absorbent article 1, the distance A6 from the outer end of the third joint portion 20Z to the inner end of the first upright portion 20Y may be shorter than the distance B2 in the width direction Y of the main body portion 10. (B2> A6). The third joint portion 20Z may be continuous with the first joint portion 20X. In this case, the distance A6 is 0.

When the distance A6 is made shorter than the distance B2, when the absorbent article 1 is folded small when the absorbent article 1 is discarded, urine is discharged from the gap between the third joint portion 20Z and the first standing portion 20Y. Hard to leak.

FIG. 5 is an explanatory diagram illustrating the effect of the absorbent article 1, and is a schematic cross-sectional view of the central axis CL2 when the absorbent article 1 is attached to the pet P. The urinary meatus UM of the pet P to which the absorbent article 1 is attached is located at a position overlapping with, for example, the absorber 13. Pet P is excreted toward the head side A.

At this time, in the direction of urination, a space surrounded by the first standing portion 20Y and the main body portion 10 is formed to block the urine U. The urine U blocked by the space surrounded by the first standing portion 20Y and the main body portion 10 passes over the absorber 13 in the process of returning to the rear (buttock side B), and thus effectively becomes the absorber 13. Be absorbed. Even if a small amount of urine U that is not absorbed by the absorber 13 exceeds the absorber 13, it is blocked by the second standing portion 30Y.

Here, as described above, the relational expression (A1 + A2)> (B1 + B2) is established, so that a space relatively larger on the head side A than the absorber 13 is formed on the buttock side B, and the excreted urine U is collected. It can be widely received and blocked. Further, the urine U can be held in the space surrounded by the first standing portion 20Y and the main body portion 10 even for a short time until the urine U is absorbed by the absorber 13. Therefore, even if urine U is vigorously excreted, urine leakage from the head side A can be suppressed. In addition, urine U can be effectively guided to the absorber 13 and absorbed.

(Locking part)
FIG. 6 is a back view of the absorbent article 1. As shown in FIG. 6, the absorbent article 1 has a locking portion 40 on one end side in the longitudinal direction of the main body portion 10. The locking portion 40 is a mechanical fastener. The locking portion 40 connects the front surface sheet 11 and the back surface layer 12 at both ends of the main body portion 10 in the longitudinal direction X, and fixes the absorbent article 1 in a cylindrical shape. As a result, the absorbent article 1 is fixed around the waist of the pet P.

In the present embodiment, the locking portion 40 is provided in the width direction of the back surface layer 12. Therefore, in the absorbent article 1, the locking portion 40 is connected to the front surface sheet 11 by superimposing the front surface on the other end side of the longitudinal direction X on the back surface of the one end side of the main body portion 10 in the longitudinal direction X. It is fixed in a shape. As described above, when the locking portion 40 is provided on the back surface layer 12, the locking portion 40 is exposed to the outside when the pet P is attached, so that the operator can easily recognize the locking portion 40 and the pet P can be easily recognized. Easy to attach to.

The locking portion 40 may be provided on the surface sheet 11. In this case, in the absorbent article 1, the locking portion 40 is connected to the back surface layer 12 by superimposing the back surface on the other end side of the longitudinal direction X on the front surface on one end side in the longitudinal direction X of the main body portion 10. It is fixed in a tubular shape.

In the absorbent article 1, the central axis CL3 in the width direction Y of the locking portion 40 is closer to the second joint portion 30X than the central position (central axis CL1) between the first joint portion 20X and the second joint portion 30X. Located in. That is, in the absorbent article 1, the locking portion 40 is provided so as to be relatively offset to the tail side B. As a result, the absorbent article 1 is fixed on the side closer to the buttocks, and the side on which the second standing portion 30Y (see FIG. 4) is arranged is relatively tightly tightened so that urine leaks from the rear. Can be suppressed.

The region provided with the locking portion 40 may be uniformly formed, but the configuration in the thickness direction (z direction) may differ depending on the region. The absorbent article 1 having such a configuration has a high rigidity region in which the rigidity of the region where the locking portion 40 is provided varies depending on the location and the rigidity is relatively high.

For example, when the locking portion 40 is provided so as to be offset from the head side A, a part of the head side A of the locking portion 40 overlaps the first leak suppressing portion 20 in a plane, and the rest is the first leak suppressing portion. It does not overlap with 20. Similarly, when the locking portion 40 is provided so as to be offset to the tail side B, a part of the tail side B of the locking portion 40 overlaps with the second leakage suppressing portion 30 in a plane, and the rest is the second leakage suppressing. It does not overlap with the portion 30 in a plane. Due to such a difference in the configuration in the thickness direction, a difference in rigidity occurs in the region where the locking portion 40 is provided.

In the above example, the region where the locking portion 40 and the first leak suppressing portion 20 or the second leak suppressing portion 30 overlap has a relatively high rigidity as the other non-overlapping regions. Such a region with high rigidity corresponds to the "high rigidity region" in the present invention.

When the pet P to which the absorbent article 1 is attached moves, a force is applied to the absorbent article 1 from a plurality of directions, and the pet P may be pulled to shift its position or its end may be turned over. When the locking portion 40 has a high-rigidity region, the high-rigidity region is less likely to be deformed than the region with relatively low rigidity (low-rigidity region), and the absorbent article 1 is misaligned or has a high-rigidity region. It is possible to suppress the turning of the edge around the.

Further, the high rigidity region may be formed by changing the configuration itself of the locking portion 40. That is, the locking portion may have a portion having a relatively different rigidity instead of being uniformly formed.

7 to 9 are explanatory views showing a modified example of the locking portion. In the following description, in the locking portion, the portion having relatively high rigidity is referred to as a high rigidity portion. Further, in the following description, it is assumed that the configuration of the absorbent article 1 in the thickness direction is uniform in the region where the locking portion is provided. That is, the region where the high-rigidity portion of the locking portion is located corresponds to the high-rigidity region.

In the locking portion 40A shown in FIG. 7, the high-rigidity portion 40x is located on the head side A in the width direction Y, and the low-rigidity portion 40y having relatively low rigidity is located on the tail side B. When the pet P wearing the absorbent article 1 is walking, the head side A of the absorbent article 1 is less likely to move than the buttock side B. Therefore, by providing the high-rigidity portion 40x on the head side A, it is possible to suppress the misalignment of the absorbent article 1 and firmly fix it to the body.

On the other hand, the pet P moves while swinging its hips from side to side when walking. In this case, by providing the low-rigidity portion 40y on the buttock side B, the absorbent article 1 worn by the pet P can flexibly follow the movement of the body and suppress the misalignment.

In the locking portion 40B shown in FIG. 8, the high-rigidity portion 40x is located on the tail side B in the width direction Y, and the low-rigidity portion 40y having relatively low rigidity is located on the head side A. When attaching the absorbent article 1, first, the rear end portion of the absorbent article 1 is pressed against the tail of the pet P for positioning, and then the first flap portion 18 and the second flap portion 19 are expanded and fitted. .. At that time, if the high-rigidity portion 40x is provided on the buttock side B, the misalignment can be suppressed when the flap portion is expanded to fit the absorbent article 1.

In the locking portion 40C shown in FIG. 9, the high-rigidity portion 40x is located near the center in the width direction Y, and the low-rigidity portion 40y is located on both the head side A and the tail side B of the high-rigidity portion 40x. When the high-rigidity portion 40x is located near the tip of the genitals of the pet P when the absorbent article 1 is attached, the genitals can be fixed by the high-rigidity portion 40x, and the absorbent article 1 is displaced to the buttock side B. Even so, the genitals are hard to expose.

(Discoloration part)
As shown in FIG. 6, the absorbent article 1 has a discolored portion 50 that discolors in response to urine. The color changing portion 50 is provided on the back surface layer 12. The discolored portion 50 is a band-shaped region extending in the longitudinal direction X, but the present invention is not limited to this, and various designs can be applied. By confirming the discoloration of the discolored portion 50, the user can recognize the guideline of the replacement time of the absorbent article 1.

The discolored portion 50 may be located closer to the second joint portion 30X than the central position (central axis CL1) between the first joint portion 20X and the second joint portion 30X. As described above, when the pet P wearing the absorbent article 1 excretes urine U, the urine U is first dammed by the first standing portion 20Y (see FIG. 4) on the head side A, and then returns to the buttock side B. However, it is absorbed by the absorber 13. That is, the absorber 13 initially easily absorbs urine U on the head side A and later easily absorbs urine U on the buttock side B. Therefore, when the discolored portion 50 located on the side of the second joint portion 30X with respect to the central axis CL1 is discolored, it can be determined that the absorber 13 on the head side A of the discolored portion 50 is also absorbing urine U. It makes it easier to make a reasonable decision that it should be replaced.

(Mark)
The absorbent article 1 has a marking portion 60. The mark portion 60 is a band-shaped printed pattern provided on the back surface layer 12. The mark portion 60 indexes the position of the end of the main body portion 10 in a state where the main body portion 10 is fixed by the locking portion 40. In the absorbent article 1, the surface sheet 11 having the other end 10z in the longitudinal direction X of the main body 10 is stacked and fixed to the locking portion 40 in a cylindrical shape, and the marking portion 60 indicates the position of the other end 10z.

When the absorbent article 1 is attached to the pet P, the user can use the absorbent article 1 in an appropriate posture by positioning the other end 10z along the mark portion 60.

The mark portion 60 has a first mark portion 60a located on the head side A in the width direction Y of the back surface layer 12 and a second mark portion 60b located on the tail side B. In the present embodiment, the first mark portion 60a and the second mark portion 60b are continuous in a band shape to form the mark portion 60. The first mark portion 60a and the second mark portion 60b may be separated from each other.

The second marking portion 60b is located inside the main body portion 10 in the longitudinal direction X with respect to the first marking portion 60a. That is, the band-shaped mark portion 60 diagonally intersects the central axis CL1.

In the absorbent article 1, the other end 10z of the main body 10 is placed along the mark portion 60 as described above and fixed by the locking portion 40, whereby the absorbent article 1 tightens the tail side B rather than the head side A. It becomes a weight. As a result, the absorbent article 1 can be easily attached to the pet P in a state where the buttock side B on which the second standing portion 30Y is arranged is tightened, and urine leakage from the buttock side B can be easily suppressed.

According to the absorbent article 1 having the above configuration, urine leakage from the forefoot side can be suppressed.

(Modification example)
FIG. 10 is a schematic view showing a modified example of the present embodiment, and is a schematic plan view showing a central portion in the longitudinal direction.

The absorbent article 2 shown in FIG. 10 has an absorbent body 15, which is convex in the central portion of the main body portion 10 in the longitudinal direction X in the direction of the second leak suppressing portion 30. That is, the absorber 15 has a first portion 151 that is rectangular in a plan view, and a second portion 152 that is convex in the direction of the second leakage suppressing portion 30.

In the absorbent article 2, the inner end 30b of the second upright portion 30Y overlaps the second portion 152 of the absorber 15 in a plan view.

As described above, when the pet P wearing the absorbent article urinates toward the head side A, the urine U is blocked by the first standing portion 20Y and absorbed by the absorber 13 in the process of returning to the rear (buttock side B). To urinate. Here, if the amount of urine U excreted is large or the momentum of excretion is strong, there is a possibility that a large amount of urine U that cannot be absorbed by the absorber 13 exceeds the absorber 13.

Even in such a case, if the absorber 15 extends to the vicinity of the second standing portion 30Y as in the absorbent article 2, the chance that the absorber 15 absorbs the urine U increases, and the urine U is collected. It is easy to absorb and it is easy to suppress urine leakage from the buttock side B.

Even with the absorbent article 2 having the above configuration, urine leakage from the forefoot side can be suppressed. Furthermore, urine leakage from the hind leg side can be suppressed.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to these examples. The various shapes and combinations of the constituent members shown in the above-mentioned example are examples, and can be variously changed based on design requirements and the like within a range not deviating from the gist of the present invention.
