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 the 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 pet in a state of being wrapped around the waist of the pet. 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 and said at the first end. Disclosed is an absorbent article for pets comprising a pair of folded lines serving as a starting point for the pair of side portions to bend toward the surface layer side.

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 portion (engaging member) on the back surface layer of one side end region in the longitudinal direction is available. (See FIG. 14) When the back surface layer is made of a soft and easily engageable material such as a non-woven fabric, the absorbent article is absorbent during the manufacturing or transporting process of the absorbent article or when the absorbent article is attached. As shown in FIG. 15, the flap portion between the one-sided edge and the engaging portion in the longitudinal direction of the article is bent toward the back surface layer side to form the front surface (that is, the back surface layer) of the flap portion on the back surface layer side. The surface of the non-woven fabric) may engage with the above-mentioned engaging portion and stick to the engaging portion.
If the flap portion is attached to the engaging portion in this way, it is necessary to peel off the flap portion attached to the engaging portion from the engaging portion when the absorbent article is attached to the body of the animal. If the absorbent article sticks to the engaging part up to one side edge in the longitudinal direction, it is difficult to peel off the flap part from the engaging part, which is a big factor when attaching the absorbent article to the animal's body. There was a risk of trouble.

Therefore, an object of the present invention is to provide an absorbent article for animals, which can be easily peeled off even if the flap portion is attached to the engaging portion, and which is less troublesome to attach to the body of an animal. And.

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.
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 in a plan view, one side edge and the one side edge in the longitudinal direction. 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 the longitudinal direction, a flap portion extending from one side edge of the engaging portion in the longitudinal direction to the one side edge of the absorbent article in the longitudinal direction is provided.
The flap portion is the absorbent article having a longitudinal length longer than the longitudinal length of the engaging portion.

In the absorbent article for animals of the first aspect, since the flap portion has a longitudinal length longer than the longitudinal length of the engaging portion, the flap portion is bent toward the first surface side as described above. Even if it is attached to the engaging portion, a portion of the flap portion that is longer than the length of the engaging portion in the longitudinal direction (hereinafter, such a portion may be referred to as a "surplus portion") is grasped as a grip portion. The flap portion can be easily peeled off from the engaging portion.
As a result, the animal-use absorbent article of the first aspect can be less troublesome when attached to the body of the animal.

Further, in another aspect (aspect 2) of the present invention, in the animal absorbent article of the above aspect 1, the engaging portion is engaged in which an engaging element is not arranged in a part in the width direction. It has an element non-arrangement part.

Since the absorbent article for animals of the second aspect has an engaging element non-arranged portion in which the engaging element is not arranged in a part in the width direction, the flap portion is bent toward the first surface side. When attached to the engaging portion, the above-mentioned non-arranged engaging element portion also functions as a grip portion, and a grip portion having a wider area can be secured.
As a result, the absorbent article of the second aspect can more easily peel off the flap portion attached to the engaging portion.

When attached to the joint portion, the above-mentioned engaging element crushed portion also functions as a grip portion, and a grip portion having a wider area can be secured.
As a result, the absorbent article of the third aspect can more easily peel off the flap portion attached to the engaging portion.

In yet another aspect (aspect 4) of the present invention, in the animal absorbent article of aspect 3, the engaging element crushed portion is one side edge and the other side end of the engaging portion in the width direction. It is arranged at a position including at least one edge of the edge.

In the animal absorbent article of the fourth aspect, the engaging element crushing portion capable of functioning as the grip portion described above is at least one end of one side edge and the other side edge in the width direction of the engaging portion. Since it is arranged at a position including the edge, when the engaging element crushed portion is grasped as a grip portion together with the above-mentioned excess portion and the flap portion is peeled off from the engaging portion, one side in the width direction of the engaging portion is used. The flap portion can be peeled off from the engaging portion with a smaller force than in the case where the flap portion can be peeled off sequentially from the end edge or the other side edge, and compared with the case where the flap portion is peeled off from the one side edge in the longitudinal direction.

In yet another aspect (aspect 5) of the present invention, in any of the animal absorbent articles of aspects 1 to 4, in plan view, one side edge of the engaging portion in the width direction and the other It has two folding lines extending in the longitudinal direction at a position passing through the side edge or at a position on the outer side in the width direction from the one side edge and the other side edge.
In the absorbent article, each of one side end portion and the other side end portion in the width direction of the absorbent article is folded toward the second surface side at the folding line.

The animal absorbent article of the fifth aspect flaps because each of the one-sided end and the other-sided end in the width direction is folded toward the second surface side at the folding line at the specific position. The portion can be made difficult to bend toward the first surface side, and even if the flap portion bends toward the first surface side and sticks to the engaging portion, the absorbent article folded toward the second surface side described above. The flap portion can be easily peeled off from the engaging portion simply by widening the one-side end portion and the other-side end portion in the width direction of the above or pulling the flap portion toward the outer side in the width direction.
As a result, the absorbent article of the fifth aspect can secure a means for peeling off the flap portion in addition to the surplus portion that functions as the above-mentioned grip portion, so that the flap portion can be pulled from the engaging portion more reliably. It can be easily peeled off.

Since it is possible to continuously secure a portion having high rigidity toward the inward side of the surface, the flap portion 7 having relatively low rigidity _{is bent to the first surface side D 1} and attached to the engaging portion 6. Even so, the flap portion 7 can be more easily peeled off from the engaging portion 6.

In the sixth embodiment, it is not necessary that all of the one-sided edge 41 of the absorber 40 in the longitudinal direction L overlaps with the engaging portion 6 in the thickness direction T, and the absorber 40 or Depending on the outer shape of the engaging portion 6, at least a part of the one-sided edge 41 of the absorber 40 in the longitudinal direction L may overlap with the engaging portion 6 in the thickness direction T.

Further, in the present invention, the longitudinal length of the absorber is not particularly limited as long as the effect of the present invention is not impaired, and an arbitrary longitudinal length according to the type, body shape, size, etc. of the animal to be worn is adopted. be able to.

The features of each of the above-described embodiments (that is, the first to sixth embodiments) can be appropriately combined, substituted, changed, or the like as long as the effects of the present invention are not impaired.

Further, the absorbent article for animals of the present invention may include any constituent member or component known in the art in addition to the above-mentioned various constituent members. For example, the animal absorbent article of the present invention can diffuse liquid excrement such as urine in the longitudinal direction and / or the width direction between the non-woven fabric forming the first surface and the non-woven fabric forming the second surface. It may be provided with a diffusible sheet.
Further, in the plan view, the absorbent article for animals of the present invention is a peripheral region of the engaging portion in the flap portion, and the longitudinal distance from the engaging portion is equal to or less than the longitudinal length of the engaging portion. The area around the engaging portion may have one or more squeezed portions recessed in the thickness direction from the first surface of the absorbent article.

When the absorbent article for animals has one or a plurality of such squeezed portions in the area around the engaging portion of the flap portion, the area around the engaging portion is less likely to be bent by the highly rigid squeezed portion. , The possibility that the flap portion described above sticks to the engaging portion can be further reduced (that is, the event itself as shown in FIG. 15 in the conventional absorbent article for animals can be made less likely to occur). Above, even if the flap portion is bent toward the first surface side and adheres to the engaging portion, the surface of the compressed portion on the first surface side in the above-mentioned area around the engaging portion is the non-woven fabric forming the first surface. Since the constituent fibers are compacted to have a high fiber density and a smooth surface, when the flap portion is peeled off from the engaging portion by grasping the above-mentioned excess portion, it can be easily peeled off with a smaller force. it can.
Further, even when the flap portion is peeled off from the engaging portion, the constituent fibers of the non-woven fabric forming the sticking surface (first surface) of the flap portion are not easily removed (that is, the engaging portion after the flap portion is peeled off). In addition, since the constituent fibers of the non-woven fabric forming the first surface of the flap portion are less likely to remain), there is also an advantage that the engaging force of the engaging portion after the flap portion is peeled off is less likely to decrease.

In the present specification, the above-mentioned "longitudinal distance from the engaging portion" is an object on the outer side in the longitudinal direction starting from one side edge (outer end edge) in the longitudinal direction of the engaging portion. The longitudinal length to the position is meant, and the above-mentioned "engagement peripheral region" is a region in which the longitudinal distance from the engaging portion is equal to or less than the longitudinal length of the engaging portion (that is, the engaging portion). From one side edge in the longitudinal direction to the portion extending outward in the longitudinal direction and the longitudinal distance from the one side edge in the longitudinal direction of the engaging portion is the same as the longitudinal length of the engaging portion. Area).

When the squeezed portion as described above is provided in the area around the engaging portion of the flap portion, the outer shape and arrangement form of the squeezed portion are not particularly limited as long as the effect of the present invention is not impaired, and the squeezed portion is, for example, a flat surface. Visually, substantially circular; elliptical; triangular; square, rhombic, etc. rectangular; cross; one or more linear (eg, continuous or discontinuous, linear, wavy, zigzag) Shape, etc.); One or more strips; Can be formed with any outer shape such as various symbols, patterns, animals and plants, design drawings of various characters, etc., and further, zigzag, grid, stripe, etc. It can be arranged in any form such as a random shape.
The squeezed portion may be formed in a region other than the region around the engaging portion of the flap portion (for example, any region from the first region to the second region or the entire region described above).
Further, the number of squeezed portions, individual dimensions, and the like are not particularly limited as long as the effects of the present invention are not impaired, and the squeezed portions can be formed by any number of one or more and any size.

Further, when the squeezing portion as described above is provided in the area around the engaging portion of the flap portion, the squeezing portion is a region having a width direction length longer than the width direction length of the engaging portion and / or the engaging portion. It is preferably arranged in a region having a longitudinal length longer than the longitudinal length. When the squeezed portion is arranged in this way, the rigidity of the squeezed portion described above makes it difficult to bend a wider area of the flap portion, and the flap portion is bent toward the first surface side to form an engaging portion. Even if they come into contact with each other, the possibility that the bent flap portion sticks to the engaging portion can be reduced more reliably.

The means for forming the pressed portion described above is not particularly limited, 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 protrusions for forming a pressed 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.

Further, when the absorbent article for animals has a joint portion for joining the back film and the back surface sheet, the joint portion has a non-overlapping portion that does not overlap with the above-mentioned pressed portion in a plan view. Is preferable. When such a joint portion has such a non-overlapping portion, the back surface sheet between the adjacent pressing portions can be made difficult to lift due to the non-overlapping portion, so that the flap portion described above is on the first surface side. Even if it is bent to be close to the engaging portion, not only the above-mentioned pressing portion but also the non-overlapping portion can be made difficult to contact with the engaging portion, and the flap portion on which the pressing portion is formed becomes the engaging portion. The possibility of sticking can be further reduced.

The above-mentioned joining means for forming the joint is not particularly limited, and any joining means known in the art (for example, heat-sealing means, bonding means using a hot melt type adhesive, etc.) can be adopted.

The method for producing an absorbent article for animals of the present invention using the above-mentioned various constituent members is not particularly limited, and any production method known in the art can be adopted. For example, the pet diaper 1 according to the first embodiment of the present invention includes various members constituting the pet diaper 1, that is, elastic members 82, 82 for forming three-dimensional gathers at the inner end in the width direction W. The pair of side sheets 5 and 5, the front sheet 2, the absorber 4, the back film 31, the pair of elastic members 81 and 81 for forming side gathers, and the back sheet 3 are engaged with each other. The parts 6 are superposed in the arrangement as shown in FIGS. 2 to 5 and joined by any joining means (for example, a hot melt adhesive bonding method, a heat sealing method, an ultrasonic joining method, etc.). Can be manufactured by
