Etc.) are not joined.
Further, as shown in FIG. 4, the pair of side sheets 5, 5 have their inner ends in the width direction W folded toward the top sheet 2, and are further folded. A pair of three-dimensional gather forming elastic members 82, 82 extending in the longitudinal direction L are arranged so as to be sandwiched between the ends. When the pair of three-dimensional gather forming elastic members 82, 82 contracts in the longitudinal direction L, the inner ends (free ends) of the pair of side sheets 5, 5 in the width direction W become closer to the top sheet 2. And a three-dimensional gather as shown in FIG. 4 can be formed. In the pet diaper 1 of the first embodiment, since such three-dimensional gathers function as leak-proof walls, liquid excretions such as urine excreted from animals are less likely to leak.

  In the first embodiment, as shown in FIG. 4, at both ends in the width direction W of the pet diaper 1, between the pair of side sheets 5 and 5 and the back sheet 3 in the longitudinal direction L. A pair of side gather forming elastic members 81, 81 extending are arranged. The pair of side gather forming elastic members 81, 81 will be described later.

In pet diaper 1 of the first embodiment described above, the engaging portion 6, as shown in FIG. 2, on the first surface S _{1 (specifically} the first region A ₁ described above, the backsheet 3 the It is arranged so as to extend in the width direction W at one face side D ₁ of the surface), in plan view, with one side end edge 61 in the longitudinal direction L which is located outward in the longitudinal direction L, the longitudinal The other edge 62 in the longitudinal direction L located on the inner side in the direction L, the one edge 63 in the width direction W located on one side in the width direction W, and the width located on the other side in the width direction W The pet diaper 1 has a rectangular outer shape that is long in the width direction W and has the other side edge 64 in the direction W.
As shown in FIG. 5, the engagement portion 6 includes a band-shaped base 6 b joined to the surface of the first surface side D ₁ of the back sheet 3 and extending in the width direction W of the pet diaper 1, and the base 6 b Is constituted by a plurality of hooks 6f (engaging elements) projecting from the same. Since the plurality of hooks 6f can be engaged with the constituent fibers of the non-woven fabric, the mechanical fastener is made of a pet. the use diaper 1 when mounted along a waist from the abdomen side of the animal, the back side of the animal, to any part of the second face side D ₂ of the surface of the surface sheet 2 made of nonwoven fabric, the aforementioned hook The part 6f can be engaged.

  In this specification, the term “engagement” means that elements having a predetermined structure are connected by being mechanically connected to each other, and the connected state is maintained unless the elements are separated with a predetermined force. Means such a state.

In the present invention, the mechanical fastener used for the engaging portion is not particularly limited as long as it can engage with an arbitrary portion of the nonwoven fabric forming the second surface. For example, a flat sheet-like base, A plurality of mushroom-type engaging projections projecting vertically from the base (ie, a shaft protruding vertically from the base, and a tip of the shaft (specifically, a tip of a shaft opposite to the base)) A mushroom-type fastener having a hook portion comprising an engaging projection having an enlarged-diameter portion bulging in a direction in which the outer peripheral surface of the shaft portion expands; a flat sheet-like base; and a vertical direction from the base. A hook portion comprising a plurality of key-shaped engaging protrusions projecting from the base (i.e., engaging protrusions having a structure in which the tip of a shaft projecting vertically from the base is folded back toward the base). Type fastener Etc. can be used.
In particular, when the mushroom type fastener is used for the engaging portion, when the engaging portion is engaged with the nonwoven fabric forming the second surface, the portion engaged with the nonwoven fabric is used for the movement of the animal or the like. Even if it is pulled in various directions by the above, since the hook portion composed of the above-mentioned mushroom-shaped engagement projection can maintain the engagement state with the nonwoven fabric in response to the force in all directions, the engagement portion and the The engagement state with the nonwoven fabric forming the two surfaces can be firmly maintained, and as a result, the absorbent article for animals can be hardly displaced from an appropriate position around the torso of the animal. Can be hardly disengaged from the torso.

  In the present invention, the constituent material of the mechanical fastener used for the engaging portion is not particularly limited, and for example, any synthetic resin such as polyester, polyolefin, polyamide, polyvinyl chloride, olefin-based elastomer, and urethane-based elastomer may be used. These synthetic resins may be used alone or in combination of two or more.

  Further, as described above, in the animal absorbent article of the present invention, the first surface having the engaging portion is the body facing surface, and the second surface is the body non-facing surface (that is, forming the first surface). The nonwoven fabric to be formed is a topsheet, and the nonwoven fabric forming the second surface is a backsheet. In such a case, the engaging portion is provided on the surface of the topsheet on the first surface side (that is, the surface of the topsheet). , The body facing surface).

In the present invention, the external shape, various dimensions, and the like of the mechanical fastener used for the engagement portion are not particularly limited as long as the effects of the present invention are not impaired, and are arbitrary according to the type, body shape, size, and the like of the animal to be worn. The external shape (for example, one or more squares, rectangles, ellipses, rhombuses, etc.) and various dimensions can be adopted, but as described above, the longitudinal length of the engaging portion (ie, animal The longitudinal length from one side edge (outer side edge) to the other side edge (inner side edge) of the engaging portion in the longitudinal direction of the absorbent article is the same as that of the absorbent article for animals. It is necessary that the length be smaller than the longitudinal length of the flap portion.
As described above, the longitudinal length of the engaging portion is smaller than the longitudinal length of the flap portion in the animal absorbent article, that is, the longitudinal length of the flap portion in the animal absorbent article is the engaging portion. Is larger than the length in the longitudinal direction, the absorbent article for animals of the present invention can be configured such that even if the flap portion is bent to the first surface side and adhered to the engagement portion as described above, the engagement in the flap portion A portion longer than the longitudinal length of the portion (that is, a surplus portion) can be grasped as a grasping portion, and the flap portion can be easily peeled off from the engaging portion.
Accordingly, the absorbent article for animals of the present invention can be made less troublesome when it is mounted on the torso of an animal.

In the animal absorbent article of the present invention, the structure of the engaging portion is not limited to the aspect of the first embodiment as long as the effect of the present invention can be exerted, as described above. Any structure can be adopted.
Hereinafter, another embodiment (that is, a second embodiment and a third embodiment) of the present invention, which is different from the first embodiment only in the structure of the engaging portion, will be described with reference to the drawings. The configuration other than the configuration different from that of the above-described first embodiment is basically the same as that of the first embodiment, and thus the description is omitted.

For example, it can be provided at any position.
As described above, when the engaging portion has the engaging element non-arranged portion in which the engaging element is not arranged in a part of the width direction, the flap portion is bent toward the first surface side and is formed on the engaging portion. Even if it is stuck, the engaging element non-arranged portion can function as a gripping portion together with the surplus portion described above, so that a gripping portion having a larger area can be secured, and as a result, the flap portion can be more easily formed. Can be peeled off from the engaging portion.

  In the present invention, the length in the width direction of the engaging element non-arranged portion is particularly limited as long as the engaging portion can exert an engaging force (joining strength) required as an engaging portion of the animal absorbent article. Instead, an arbitrary length in the width direction can be adopted, but from the viewpoint of more reliably obtaining the function as the above-described gripping portion, the engaging element non-arranged portion has a finger of a wearer such as an animal owner. It is preferable to have a length in the width direction that allows insertion (for example, a length in the range of 6 mm to 20 mm).

In the present invention, the arrangement of the engaging element non-arranged portion is not particularly limited, and is not particularly limited as long as the engaging portion can exert the necessary engaging force as the engaging portion of the animal absorbent article.

  In the present invention, the length in the width direction of the above-described engaging element crushing portion is not particularly limited as long as the engaging portion can exert the necessary engaging force as the engaging portion of the absorbent article for animals, and may have any width. Although the length in the directional direction can be adopted, the engaging element crushing portion is wide enough to allow the finger of the wearer such as the animal owner to insert the finger in order to more reliably obtain the function as the gripping portion described above. It preferably has a length in the direction (for example, a length in a range of 6 mm to 20 mm).

Further, in the present invention, the arrangement of the engaging element crushing portion is not particularly limited as long as the engaging portion can exert the necessary engaging force as the engaging portion of the absorbent article for animals. The crushed portion can be arranged at any position such as only one end in the width direction or the center in the width direction, in addition to or instead of both ends in the width direction described above. As in the third embodiment, it is preferable that the engagement portion is disposed at a position including at least one of the one side edge and the other side edge in the width direction.
The engaging element crushing portion that can function as a grip portion is disposed at such a position (that is, a position including at least one of the one side edge and the other side edge in the width direction of the engaging portion). When the engagement element crushed portion is gripped as a grip portion together with the surplus portion described above and the flap portion is peeled off from the engagement portion, one side edge to the other side edge in the width direction of the engagement portion. The flap portion can be peeled off from the engagement portion with a smaller force as compared with a case where the flap portion is peeled off from one edge in the longitudinal direction.

  In the present invention, the means for forming the engaging element crushing portion in the engaging portion is not particularly limited, and the engaging element in a predetermined portion of the engaging portion is formed by using any known heating or non-heating pressurizing means. It can be formed by crushing.

  Note that, in the present invention, the engagement portion may have both the engagement element non-arranged portion in the above-described second embodiment and the engagement element crushing portion in the third embodiment.

  In the sixth embodiment, it is not necessary that all of the one side edge 41 of the absorber 40 in the longitudinal direction L overlap the engaging portion 6 in the thickness direction T. It is sufficient that at least a part of the one side edge 41 in the longitudinal direction L of the absorber 40 overlap the engaging portion 6 in the thickness direction T according to the outer shape and the like of the engaging portion 6.

  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 any 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, replaced, changed, and the like, as long as the effects of the present invention are not impaired.

In addition, the absorbent article for animals of the present invention may include, in addition to the various constituent members described above, any constituent members or constituent elements known in the art. For example, the absorbent article for animals of the present invention can diffuse liquid excrement such as urine in the longitudinal direction and / or the width direction between the nonwoven fabric forming the first surface and the nonwoven fabric forming the second surface. A diffusible sheet may be provided.
Furthermore, the animal absorbent article of the present invention is, in plan view, a peripheral region of the engaging portion in the flap portion, and a longitudinal distance from the engaging portion is equal to or less than a longitudinal length of the engaging portion. One or a plurality of squeezed portions depressed in the thickness direction from the first surface of the absorbent article may be provided in the region around the engaging portion.

When the absorbent article for animals has one or a plurality of such compressed portions in the region around the engaging portion of the flap portion, the region around the engaging portion is hard to be bent by the highly rigid compressed portion. Therefore, the possibility that the above-mentioned flap portion is stuck to the engagement portion can be further reduced (that is, the event itself shown in FIG. 15 in the conventional absorbent article for animals can be less likely to occur). Even if the flap portion is bent to the first surface side and stuck to the engaging portion, the surface of the pressing portion in the peripheral region of the engaging portion on the first surface side is formed of the non-woven fabric forming the first surface. Since the constituent fibers are compacted and have a high fiber density and a smooth surface, when the above-mentioned surplus portion is gripped and the flap portion is peeled off from the engagement portion, it can be easily peeled off with a smaller force. it can.
Further, even when the flap portion is peeled off from the engagement portion, the constituent fibers of the nonwoven fabric forming the sticking surface (first surface) of the flap portion are difficult to fall off (that is, the engagement portion after the flap portion is peeled off). Furthermore, since the constituent fibers of the nonwoven fabric forming the first surface of the flap portion are less likely to remain), there is an advantage that the engagement force of the engagement 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” refers to an object on the outer side in the longitudinal direction starting from one side edge (outer side edge) in the longitudinal direction of the engaging portion. Means the length in the longitudinal direction up to the position, and the above-described “region around the engaging portion” is a region where the longitudinal distance from the engaging portion is equal to or less than the longitudinal length of the engaging portion (that is, the area of the engaging portion). A portion extending from one side edge in the longitudinal direction to the outside in the longitudinal direction and extending from the one side edge in the longitudinal direction of the engaging portion to a portion where the longitudinal length is the same as the longitudinal length of the engaging portion. Area).

When providing the above-described compressed portion in the engaging portion peripheral region of the flap portion, the outer shape and arrangement of the compressed portion are not particularly limited as long as the effects of the present invention are not impaired, and the compressed portion is, for example, a flat surface. A substantially circular shape; an elliptical shape; a triangular shape; a rectangular shape such as a square or a rhombus; a cross shape; one or more linear shapes (for example, continuous or discontinuous, linear, wavy, or zigzag lines) Shape or the like); one or a plurality of strips; can be formed in an arbitrary external shape such as a design drawing shape of various symbols and patterns, animals and plants, various characters, etc., and further, a staggered shape, a lattice shape, a stripe shape, They can be arranged in any form such as a random form.
In addition, the above-mentioned squeezing part may be formed in a field other than a field surrounding an engaging part of a flap part (for example, any field from the above-mentioned 1st field to the 2nd field, the whole field, etc.).
In addition, the number and dimensions of the pressed portions are not particularly limited as long as the effects of the present invention are not impaired, and the pressed portions can be formed in any number of one or more and in any size.

  Furthermore, when providing the above-mentioned squeezing part in the surrounding area of the engaging part of the flap part, the squeezing part is a region having a width direction length longer than the width direction length of the engaging part and / or the engaging part. It is preferable to be arranged in a region having a longitudinal length longer than the longitudinal length. When the squeezing portion is arranged in this manner, the above-described rigidity of the squeezing portion makes it difficult to bend a wider area of the flap portion, and furthermore, the flap portion is bent toward the first surface side to form the engaging portion. Even if they come into contact, the possibility that the bent flap portion sticks to the engagement portion can be reduced more reliably.

  The means for forming the above-mentioned compressed portion is not particularly limited, and any embossing means known in the art can be employed. For example, the nonwoven fabric forming the first surface (that is, the back sheet or the topsheet) alone, or a laminate including at least the nonwoven fabric forming the first surface and the back film is formed by one or more protrusions for forming a compressed portion. By squeezing in the thickness direction from the first surface side of the nonwoven fabric forming the first surface by using a heated or non-heated embossing means provided with the above, the above-described compressed portion can be formed.

  In addition, when the absorbent article for animals has a joining portion that joins the back film and the back sheet, the joining portion has a non-overlapping portion that does not overlap with the above-described compressed portion in plan view. Is preferred. When such a joint portion has such a non-overlapping portion, the non-overlapping portion makes it difficult for the back sheet between the adjacent pressing portions to float up. Even if it is bent to be close to the engaging portion, not only the above-mentioned compressed portion but also the non-overlapping portion can be made difficult to contact with the engaging portion, and the flap portion formed with the compressed portion is attached to the engaging portion. The possibility of sticking can be further reduced.

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

  The method for producing the absorbent article for animals of the present invention using the above 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, three-dimensional gather forming elastic members 82, 82 at the inner end in the width direction W. And a pair of side sheets 5, 5, on which the top sheet 2, an absorber 4, a back film 31, a pair of side gather forming elastic members 81, 81, and a back sheet 3 are provided. The part 6 is overlapped in an arrangement form as shown in FIGS. 2 to 5 and joined by an arbitrary joining means (for example, an adhesive method using a hot melt adhesive, a heat sealing method, an ultrasonic joining method, or the like). Can be manufactured.

  The present invention can be applied to various animal absorbent articles such as pet (light) incontinence pads, for example, in addition to the pet diapers of the above embodiments. Further, the absorbent article for animals of the present invention is not limited to the above-described embodiments, and can be appropriately combined, substituted, changed, and the like without departing from the purpose and spirit of the present invention. In this specification, ordinal numbers such as "first" and "second" are used to distinguish items to which the ordinal numbers are attached, and mean the order, priority, importance, and the like of each item.
