Description

The present invention relates to absorbent articles for animals such as disposable diapers used for animals such as dogs and cats.

As an animal absorbent article for treating excrement such as urine excreted by an animal such as a dog or a cat, a band-shaped animal absorbent article worn around the body of an animal is known.

As such a strip-shaped absorbent article for animals, for example, in Patent Document 1, the surface layer side of the first end portion in the longitudinal direction faces the body side of the animal in a state of being wrapped around the body of the animal. The pet absorbent article is arranged so that the front surface layer side of the second end portion in the longitudinal direction is detachably attached to the back surface layer side of the first end portion, and the back surface layer of the first end portion. A locking member that is arranged on the side and has a rectangular shape and whose longitudinal direction extends along the width direction of the pet absorbent article, and a locking member that is formed at the first end portion and is formed at the first end portion. An absorbent article for pets comprising a pair of fold lines serving as a starting point for the pair of side portions to bend toward the surface layer side is disclosed.

Japanese Unexamined Patent Publication No. 2012-205578

However, like the absorbent article for pets disclosed in Patent Document 1, an absorbent article for animals having an engaging member (engaging portion) on the back surface layer of one side end region in the longitudinal direction is available. (See FIG. 13) When the back surface layer is formed of a soft and easily engageable material such as a non-woven fabric, the longitudinal direction is used during the manufacturing or transporting process of the absorbent article or when the absorbent article is attached. A part of the one-sided end region (specifically, a flap portion between the one-sided end edge and the engaging portion in the longitudinal direction of the absorbent article or a portion inward in the longitudinal direction from the engaging portion. (Hereinafter, these parts may be collectively referred to simply as "flap portion, etc.")) is bent toward the back surface layer side as shown in FIGS. 14 (a) and 14 (b), and the back surface of the region is concerned. The surface on the layer side (that is, the surface of the non-woven fabric forming the back surface layer) may engage with the above-mentioned engaging portion and stick to the engaging portion.
If the flap portion or the like sticks to the engaging portion in this way, it is necessary to peel off the flap portion or the like attached to the engaging portion from the engaging portion when the absorbent article is attached to the body of the animal. However, since the constituent fibers of the non-woven fabric forming the back surface layer remain in the engaging portion after the flap portion and the like are peeled off, the engaging force (bonding strength) of the engaging portion is reduced, and the animal's body is affected. There was a risk that the attached absorbent article would easily come off.

Therefore, an object of the present invention is to provide an absorbent article for an animal, in which the engaging force of the engaging portion is unlikely to decrease and the engaging force is not easily disengaged from the body of the attached animal.

One aspect (aspect 1) of the present invention has a longitudinal direction, a width direction, and a thickness direction orthogonal to each other, and in the thickness direction, a first surface and a second surface opposite to the first surface are formed. An absorbent article for animals that has and is worn so that the longitudinal direction is along the circumference of the animal's torso.
The absorbent article has a non-woven fabric forming the first surface and a non-woven fabric forming the second surface in the thickness direction, and has one side edge in the longitudinal direction and a non-woven fabric forming the second surface in a plan view. Between the other side edges, it has a first region, a central region and a second region that divide the absorbent article into three equal parts in the longitudinal direction.
Further, the absorbent article is
An engaging portion extending in the width direction on the first surface of the first region and detachably engaging with the second surface of the second region.
In a plan view, the longitudinal distance from the engaging portion overlaps at least partially with respect to the area around the engaging portion where the longitudinal distance of the engaging portion is equal to or less than the longitudinal length of the engaging portion, and the thickness from the first surface to the first surface. It comprises a squeezed portion forming region having one or more squeezed portions recessed in a direction.
The first region is the absorbent article having a squeezed area ratio larger than the squeezed area ratio in the second region.

The animal-use absorbent article of the first aspect has one or more squeezed portions in the area around the engaging portion of the first region, and the area around the engaging portion is hard to bend due to the highly rigid squeezed portion. Therefore, it is possible to prevent the above-mentioned flap portion and the like from sticking to the engaging portion, and as a result, it is possible to prevent the engaging force of the engaging portion from being lowered.
Further, even if the area around the engaging portion is bent toward the first surface side and the flap portion or the like is attached to the engaging portion, the surface on the first surface side of the squeezed portion forms the first surface. Since the constituent fibers of the non-woven fabric are compacted to have a high fiber density and a smooth surface, the flap portion and the like attached to the engaging portion are easily peeled off from the engaging portion, and the flap portion and the like are further separated from the engaging portion. The constituent fibers of the non-woven fabric forming the sticking surface (first surface) of the flap portion and the like are hard to come off even when peeled off from the flap portion (that is, the flap portion and the like are attached to the engaging portion after the flap portion and the like are peeled off. The constituent fibers of the non-woven fabric forming the first surface of the above are less likely to remain), and as a result, the engaging force of the engaging portion is less likely to decrease.
Further, the animal absorbent article of the first aspect is configured such that the squeezed area ratio in the first region is larger than the squeezed area ratio in the second region, and the second region is relative. Because of its low rigidity and flexibility, it can engage with the engaging portion of the first region with high joint strength while following the body shape of the animal.
From the above, in the absorbent article for animals of the first aspect, the engaging force of the engaging portion is unlikely to decrease, and it is difficult to disengage from the body of the attached animal.

Further, in another aspect (aspect 2) of the present invention, in the absorbent article for animals of the above aspect 1, the squeezed portion forming region has a width direction length longer than the width direction length of the engaging portion. ..

In the absorbent article for animals of the second aspect, since the squeezed portion forming region has a width direction length longer than the width direction length of the engaging portion, a wider region in the width direction such as the flap portion can be covered. It can be made difficult to bend, and even if the flap part etc. is bent (especially when the end part in the width direction of the absorbent article is also bent), the bent flap part etc. can be attached to the engaging part. The sex can be further reduced.
From the above, in the absorbent article for animals of the second aspect, the engaging force of the engaging portion is less likely to decrease, and it is possible to make it more difficult to disengage from the body of the attached animal.

In yet another aspect (aspect 3) of the present invention, in the animal absorbent article of aspect 1 or 2, the squeezed portion forming region is located on one side of the engaging portion in the longitudinal direction in the longitudinal direction. It extends from the edge to the one side edge of the absorbent article in the longitudinal direction.

In the animal absorbent article of the third aspect, the squeezed portion forming region extends from one side edge in the longitudinal direction of the engaging portion to one side edge in the longitudinal direction of the absorbent article in the longitudinal direction, that is, a flap portion. Since it extends over the entire surface, it is possible to prevent the flap portion from bending, and even if the flap portion is bent, the bent flap portion sticks to the engaging portion regardless of the bending method. The possibility can be reduced more reliably.

In yet another aspect of the present invention (aspect 4), in any of the animal absorbent articles of aspects 1-3, the squeezed portion forming region is in the longitudinal direction and in the longitudinal direction of the engaging portion. It extends outward from one side edge in the longitudinal direction and has a longitudinal length longer than the longitudinal length of the engaging portion.

In the animal absorbent article of the fourth aspect, the squeezed portion forming region extends in the longitudinal direction from one side edge in the longitudinal direction of the engaging portion toward the outward side in the longitudinal direction and the engaging portion. Since it has a longitudinal length longer than the longitudinal length of the flap portion, even if the flap portion is formed longer in the longitudinal direction, the portion that affects the attachment of the flap portion to the engaging portion is affected. Bending can be made less likely to occur, and even if the flap portion is bent, the possibility that the bent flap portion will stick to the engaging portion can be more reliably reduced.
Further, in the animal-use absorbent article of the present aspect 4, the squeezed portion forming region extends in the longitudinal direction from one side edge in the longitudinal direction of the engaging portion toward the outward side in the longitudinal direction and engages. The flap portion is engaged because it has a longitudinal length longer than the longitudinal length of the joint, that is, the flap portion has a longitudinal length longer than the longitudinal length of the engaging portion. When attached to the joint, the flap portion can be easily peeled off by grasping the grip portion using a portion longer than the longitudinal length of the engaging portion in the flap portion as a grip portion, and is an absorbent article for animals. There is also an advantage that it is possible to reduce the trouble of attaching the to the body of the animal.

In yet another aspect (aspect 5) of the present invention, in any of the animal absorbent articles of aspects 1 to 4, the squeezed portion forming region is in the longitudinal direction and the engaging portion is in the longitudinal direction. It extends inward in the longitudinal direction from the other end edge in the above and has a longitudinal length longer than the longitudinal length of the engaging portion.

In the animal absorbent article of the fifth aspect, the squeezed portion forming region extends in the longitudinal direction from the other side edge in the longitudinal direction of the engaging portion toward the inward side in the longitudinal direction and the engaging portion. Since it has a longitudinal length longer than that of the engaging portion, it is unlikely that the portion that affects the attachment to the engaging portion is bent, especially in the portion on the inner side in the longitudinal direction of the engaging portion. In addition, even if the portion on the inner side in the longitudinal direction from the engaging portion is bent, the possibility that the bent portion will stick to the engaging portion can be reduced more reliably.

In yet another aspect of the present invention (aspect 6), in any of the animal absorbent articles of aspects 1-5 above,
The absorbent article includes a liquid-impermeable member arranged between the non-woven fabric forming the first surface and the non-woven fabric forming the second surface.
At least, a joint portion for joining the surface of the liquid-impermeable member on the first surface side and the surface of the non-woven fabric forming the first surface on the second surface side is further provided.
The joint portion has a non-overlapping portion in the squeezed portion forming region that does not overlap with the squeezed portion in a plan view.

In the animal-use absorbent article of the sixth aspect, the joint portion for joining the surface of the liquid-impermeable member on the first surface side and the surface of the non-woven fabric forming the first surface on the second surface side is pressed as described above. Since the portion-forming region has a non-overlapping portion that does not overlap with the squeezed portion in a plan view, it is difficult to lift the non-woven fabric forming the first surface between the adjacent squeezed portions in the squeezed portion-forming region. Can be done. As a result, even if the flap portion or the like is bent and the pressed portion forming region is close to the engaging portion, not only the pressing portion but also the non-overlapping portion is less likely to come into contact with the engaging portion. The possibility that the portion forming region sticks to the engaging portion can be further reduced.

In yet another aspect of the present invention (Aspect 7), in any of the animal absorbent articles of aspects 1-6 above,
The absorbent article overlaps with the longitudinal central axis extending in the width direction in a plan view, and the first folding line extending in the width direction for folding the absorbent article so that the second surface is inside. When,
In plan view, between the one side edge of the absorbent article in the longitudinal direction and the first fold line, and between the other side edge of the absorbent article in the longitudinal direction and the first fold line. It has two second folding lines extending in the width direction for folding the absorbent article folded at the first folding line so that the engaging portion is inside. hand,
The absorbent article has a line-symmetrical relationship with the engaging portion with the second folding line located between one side edge of the absorbent article in the longitudinal direction and the first folding line as a target axis. The first surface of the region further has an inwardly squeezed portion forming region having one or more squeezed portions recessed from the first surface in the thickness direction.

The animal-use absorbent article of the seventh aspect is recessed in the thickness direction from the first surface on the first surface of a region having a line-symmetrical relationship with the engaging portion with the second folding line as the target axis. Alternatively, since it further has an inwardly squeezed portion forming region having a plurality of squeezed portions, even if a plurality of absorbent articles are folded and packaged at the first fold line and the second fold line, the inside of the folded absorbent article In the above-mentioned engaging portion, it is difficult for the above-mentioned engaging portion to engage with the inwardly squeezed portion forming region, and the engaging force of the engaging portion is less likely to decrease.

According to the present invention, it is possible to provide an absorbent article for an animal, in which the engaging force of the engaging portion is unlikely to decrease and the engaging force is not easily disengaged from the body of the attached animal.

Is defined as a region that extends inward in the longitudinal direction and has a longitudinal length from each edge within 33% of the longitudinal length (this longitudinal length is 100%). The same applies to the one-sided end and the other-sided end in the width direction of the absorbent article for animals.
The one-sided edge and the other-side edge, and the one-sided end and the other-side end in these various directions are various members, various regions, and the like (for example, a surface sheet, etc.) constituting the absorbent article for animals. The same applies to an absorber, a back sheet, an engaging portion, a squeezed portion forming region, etc.).
Further, in the present specification, the “one side” and the “other side” in various directions such as various members and various regions constituting the absorbent article for animals are also referred to as “one side” and “the other side” in various directions of the absorbent article for animals. Used to correspond to "one side" and "the other side".

As shown in FIGS. 3 to 5, the pet diaper 1 of the first embodiment described above has a back film 31 arranged between the absorber 4 and the back surface sheet 3 and a second surface side of the front surface sheet 2. In D ₂ , a pair of side sheets 5 and 5 extending in the longitudinal direction L arranged at both ends in the width direction W of the pet diaper 1 and the first surface S ₁ of the _{above-mentioned first region A 1} The pet diaper 1 is provided with an engaging portion 6 which is arranged so as to extend in the width direction W and can be detachably engaged with the second surface S _{2 of the above-mentioned second region A 2.} It is configured so that it can be steadily attached to the body of an animal so that liquid excrement such as urine excreted from the animal does not leak to the outside.

As shown in FIG. 5, the above-mentioned engaging portion 6 is a strip-shaped base portion joined to _{the surface of the first surface side D 1} of the back surface sheet 3 (that is, the first surface S _{1 of the pet diaper 1).} It is composed of a mechanical fastener composed of 6b and a plurality of hook portions 6f protruding from the base portion 6b, and when the pet diaper 1 is worn from the abdominal side of the animal along the waist circumference, the back side of the animal. in, it is possible to engage the hook portion 6f of the above any portion of the second face side D ₂ of the surface of the surface sheet 2 made of nonwoven fabric (i.e., second side S ₂ of the pet diaper _1). By providing such an engaging portion 6, the pet diaper 1 can be accurately worn at an appropriate position of the animal's torso according to the size of the animal's torso.

As shown in FIGS. 1 to 4, the pet diaper 1 of the first embodiment has the above-mentioned pair of side sheets 5, 5 and the back surface sheet 3 at both ends of the pet diaper 1 in the width direction W, respectively. A pair of side gather forming elastic members 81 and 81 extending in the longitudinal direction L and a pair of side sheets 5 and 5 arranged between the two side sheets 5 and 5 on the inner side of the width direction W, respectively. A pair of elastic members 82, 82 for forming three-dimensional gathers extending in the longitudinal direction L are further provided, and the entire pet diaper 1 is provided with a predetermined elasticity in the longitudinal direction L. When the pet diaper 1 is attached to the animal's body, the pet's diaper 1 contracts in the animal's waist circumference direction (that is, the longitudinal direction L in the plan view), and it becomes easy to adhere to the animal's body shape and the like. ing. Further, the pet diaper 1 attached to the body of the animal can be expanded and contracted in the direction around the body of the animal by the action of each of the above-mentioned elastic members in accordance with the change in the size of the waist circumference due to the movement of the animal such as breathing. Therefore, it is easy to maintain the state in which the pet diaper 1 is in close contact with the body of the animal for a long period of time.

Then, as shown in FIGS. 1, 2, 5, and 6, the pet diaper 1 of the first embodiment is outward in the longitudinal direction L with respect to the above-mentioned engaging portion 6 in a plan view. side (i.e., the flap portion P) longitudinal distance D _P is equal to or less than the longitudinal length D ₆ of the engaging portion 6 of the positioned and the engaging portion 6, the engagement portion of the outer side of the longitudinal direction L It includes a compressing portion forming region 7 having a plurality of compressed portions 71 recessed in the thickness direction T from the first surface S ₁ of the overlap with the peripheral area a _P and pet diaper 1, further first region of the above A ₁ has a squeezed portion area ratio larger than the squeezed portion area ratio in the second region A _2. The present in the pet diaper 1 of the first embodiment, since the compressed portion in the second area A ₂ is not formed, compression portions area ratio in the second region A ₂ is 0%.

Thus pet diaper 1 of the first embodiment, the first region A ₁ of the engaging portion surrounding region A _P have a plurality of compressed portions 71, the engaging portion surrounding region A _P rigidity Since it is difficult to bend due to the high pressing portion 71, it is possible to prevent the flap portion P from sticking to the engaging portion 6 (that is, in the conventional absorbent article for animals, FIG. 14 ( It is possible to make it difficult for the phenomenon as shown in a) to occur), and as a result, it is possible to make it difficult to reduce the engaging force of the engaging portion 6.
Further, if the engaging portion surrounding region A _P is bent on the first surface side D _1, as the flap portion P is stuck to the engagement portion 6, the first face side D ₁ of the surface of the compressing portion 71 since the non-woven fabric is compacted configuration fibers (backsheet 3) fiber density to form the first surface S ₁ is has become high and smooth surface, the flap portion P which stuck to the engagement portion 6 is engaged easily peeled off from the engaging portion 6, further, when the flap portion P is detached from the engaging portion 6 also, sticking surface of the flap portion P (i.e., the first surface S ₁₎ is configured fibers of the nonwoven fabric forming the hardly slipping off cage (i.e., the engaging portion 6 after peeled off flap portion P, which is non-woven fibers constituting forming the first surface S ₁ of the flap portion P is less likely to remain), resulting in the engagement portion The engaging force of No. 6 is less likely to decrease.
Additionally, pet diaper 1 of the present first embodiment, compressing portions area ratio in the first region A ₁ is be configured to be larger than the compressed portion area ratio in the second region A _2, the second area A _2, a relatively low rigidity, because it is flexible, while following the animal body shapes such as dogs can engage at a high bonding strength between the engaging portion 6 of the first region a _1.
From the above, in the pet diaper 1 of the first embodiment, the engaging force of the engaging portion 6 is unlikely to decrease, and it is difficult to disengage from the body of the attached animal.

In the animal-use absorbent article of the present invention, the arrangement position of the squeezed portion forming region, the form of the squeezed portion, and the like are not limited to those of the embodiment, and the squeezed portion is as in the embodiment described later. The forming region 7 is located in a portion Q on the inner side in the longitudinal direction L with respect to the above-mentioned engaging portion 6, and the longitudinal distance D _Q from the engaging portion 6 is the longitudinal length D _{6 of the engaging portion 6.} hereinafter become, may be disposed at a position overlapping an engagement portion surrounding region a _Q of the inner side of the longitudinal direction L, also compression of the compressing portion forming region is long formed one or more Just do it.
When compressing portion forming region 7 described above is disposed in a position overlapping an engagement portion surrounding region A _Q portion Q of the inner side of the longitudinal direction L of the above, the engaging portion surrounding region A _Q is rigid Since the high squeezing portion 71 makes it difficult to bend, it is possible to make it difficult for the above-mentioned inner portion Q in the longitudinal direction L to stick to the engaging portion 6 (that is, in a conventional absorbent article for animals). , The event as shown in FIG. 14B can be made less likely to occur), and as a result, the engaging force of the engaging portion 6 can be made less likely to decrease.
Further, even if the area A _Q around the engaging portion is bent toward the first surface side D ₁ and the above-mentioned inner side portion Q is attached to the engaging portion 6, the first surface side of the squeezed portion 71 is formed. As described above, the surface of D ₁ is a smooth surface with high fiber density due to the constituent fibers of the non-woven fabric forming _{the first surface S 1 being compacted, so that the surface is attached to the engaging portion 6 as described above.} The portion Q on the inner side in the longitudinal direction L of the above is easily peeled off from the engaging portion 6, and even when the portion Q is peeled off from the engaging portion 6, the sticking surface of the portion Q (that is, the first surface S _1). ) constituent fibers of the nonwoven fabric to be formed is not easily fall off (i.e., the engaging portion 6 after peeling off the portion Q of the inner side of the above, the first surface S ₁ of the portion Q of the inner side of the above The constituent fibers of the non-woven fabric to be formed are less likely to remain), and as a result, the engaging force of the engaging portion 6 can be less likely to be reduced.

The pet diaper 1 of the first embodiment described above is attached to the body of an animal as follows. Note that FIG. 7 is a schematic view showing a state in which the pet diaper 1 of the first embodiment is attached to a male dog (an example of an “animal” in the present invention).
First, in the pet diaper 1, the longitudinal direction L intersects the anterior-posterior direction of the animal (that is, the width direction W corresponds to the anterior-posterior direction of the animal), and the absorber 4 faces the excretory part (urinary tract opening) of the animal.

Here, in the present specification, the "compressed area ratio" means the ratio (%) of the total planar area of the squeezed portion to the planar area of the target region (for example, the first region, the second region, etc.). For example, the total plan-view area of the squeezed part is calculated from the plan-view area and the number of each squeezed part measured by using an arbitrary magnifying observation means such as a magnifying mirror or a microscope, and this is separately calculated. It can be obtained by dividing by the plane viewing area of the measured target area and multiplying by 100.
The magnitude relationship of the area ratio of the pressed portion between the regions can be determined visually when it is clear by visual inspection or the like as in the first embodiment described above, and when it is difficult to judge by visual inspection or the like, it is possible to judge by visual inspection or the like. As described above, it can be determined by calculating and comparing the area ratio of the pressed portion of each region.

As described above, the animal absorbent article of the present invention is configured such that the squeezed area ratio in the first region is larger than the squeezed area ratio in the second region, and the second region is relative. Because of its low rigidity and flexibility, it can engage with the engaging portion of the first region with high joint strength while following the body shape of the animal.

Has a diaper. As described above, when the squeezed portion forming region 7 has a width direction length longer than the width direction length of the engaging portion 6, it is possible to make it difficult to bend a wider region of the flap portion P in the width direction W. In addition, even if the flap portion P is bent (especially when the end portion of the width direction W of the pet diaper 1 is also bent), the bent flap portion P may stick to the engaging portion 6. It can be further reduced. As a result, the engaging force of the engaging portion 6 is less likely to decrease, and it is possible to make it more difficult to disengage from the body of the attached animal.

Further, in the pet diaper 1 of the first embodiment described above, the squeezed portion forming region 7 is located in the longitudinal direction L from one side edge 61 in the longitudinal direction L of the engaging portion 6 to the longitudinal direction L of the pet diaper 1. Extends to one side edge 11 in. In this way, the squeezed portion forming region 7 extends from the one-sided edge 61 in the longitudinal direction L of the engaging portion 6 to the one-sided edge 11 in the longitudinal direction L of the pet diaper 1 in the longitudinal direction L. That is, when the squeezed portion forming region 7 extends over the entire flap portion P, it is possible to make it difficult for the flap portion P to bend, and even if the flap portion P is bent, how to bend it. Regardless, the possibility that the bent flap portion P sticks to the engaging portion 6 can be more reliably reduced.

In the present invention, the means for forming the pressed portion is not particularly limited as long as the effect of the present invention is not impaired, and any embossing means known in the art can be adopted. For example, a single non-woven fabric (that is, a back surface sheet or a front surface sheet) forming the first surface, or a laminate containing at least the non-woven fabric forming the first surface and a back film is formed by one or a plurality of projecting portions for forming a squeezed portion. The above-mentioned pressed portion can be formed by pressing the non-woven fabric forming the first surface in the thickness direction from the first surface side by using a heated or unheated embossing means provided with.

In the animal-use absorbent article of the present invention, the arrangement position and arrangement form of the pressed portion forming region are not limited to those of the above-mentioned first embodiment as long as they do not impair the effect of the present invention, and the animal to be worn. It is possible to adopt an arbitrary arrangement position and arrangement form according to the type, body shape, size, and the like.
