DETAILED DESCRIPTION

[0033] [Outline of Embodiments of the Present Application]

[0034] The outline of the embodiments of the present application is explained with reference to the items listed below. Furthermore, the present application contains any combination of the items below.

[0035] (Item 1)

[0036] A manufacturing method of a pet absorbent article according to an aspect includes: a step of preparing a first sheet member in a strip shape extending in a longitudinal direction; a step of intermittently applying a hot melt adhesive to one or more elastic members having stretchability to form a plurality of adhesive regions of the one or more elastic members arranged at intervals in the longitudinal direction, and bonding the plurality of adhesive regions of the one or more elastic members to the first sheet member in a state in which the one or more elastic members are elongated in the longitudinal direction; a step of laminating a second sheet member in a strip shape extending in the longitudinal direction on the first sheet member across the one or more elastic members to form a complex body including the first sheet member, the one or more elastic members, and the second sheet member; and a step of cutting notches in the complex body from the first sheet member side or the second sheet member side to cut the one or more elastic members between the plurality of adhesive regions, contract the one or more elastic members between the plurality of adhesive regions, and thereby form a plurality of high stretch regions arranged at intervals in the longitudinal direction in the complex body.

[0037] In the manufacturing method of the pet absorbent article according to the aspect, the hot melt adhesive is intermittently applied to the elastic member to form a plurality of adhesive regions of the elastic member arranged at intervals in the longitudinal direction in the first sheet member. Also, the elastic member is cut between the plurality of adhesive regions to form a plurality of high stretch regions arranged at intervals in the longitudinal direction in the complex body. That is, in the manufacturing method, the region to which the hot melt adhesive is applied becomes the high stretch region. According to the manufacturing method, the position of the high stretch region can be controlled depending on the position at which the hot melt adhesive is applied, and thus the stretchability can be easily imparted to a desired region of the pet absorbent article.

[0038] (Embodiment 2)

[0039] The manufacturing method of the pet absorbent article according to Embodiment 1 can further include a step of arranging an absorbent on the first sheet member after the plurality of high stretch regions are formed, and a step of laminating a third sheet member in a strip shape extending in the longitudinal direction on the first sheet member across the absorbent, the absorbent being arranged between the plurality of high stretch regions when viewed in a thickness direction of the complex body. In this case, the absorbent can be prevented from being cut when notches are cut in the complex body to form the plurality of high stretch regions. Also, since the absorbent is arranged between the plurality of high stretch regions, the absorbent is less likely to be wrinkled due to contraction of the high stretch regions. Thus, the absorbent can effectively absorb urine.

[0040] (Embodiment 3)

[0041] In the method for manufacturing the absorbent article for pets according to item 2, the first sheet member can include a nonwoven fabric layer, the second sheet member can include a resin film layer, and the third sheet member can include a nonwoven fabric layer. In this case, one or more elastic members can be easily attached to the first sheet member. In addition, the second sheet member can be used to impart liquid impermeability to a portion of the absorbent article for pets, and the third sheet member can be used to impart a good skin feel to the absorbent article for pets.

[0042] (ITEM 4)

[0043] In the method for manufacturing the absorbent article for pets according to item 2 or 3, the absorbent body can be disposed between the cutout and the high stretch region adjacent to the cutout among the plurality of high stretch regions. In this case, leakage of urine discharged to the absorbent body through the cutout can be suppressed.

[0044] (ITEM 5)

[0045] The method for manufacturing the absorbent article for pets according to any one of items 2 to 4 can further include a step of cutting the composite and the third sheet member between the cutout and the high stretch region adjacent to the cutout among the plurality of high stretch regions to produce the absorbent article for pets including the composite, the absorbent body, and the third sheet member. In this case, a suitable absorbent article for pets can be produced without cutting the high stretch region and the cutout.

[0046] (ITEM 6)

[0047] The method for manufacturing the absorbent article for pets according to any one of items 1 to 5 can further include a step of attaching the joining sheet to the outer surface of the second sheet member in a manner of covering the cutout. In this case, some members can be prevented from being caught in the cutout of the composite and causing damage to the composite during the production of the absorbent article for pets. In addition, the rigidity of the composite can be increased by the joining sheet, and the cutout can be prevented from excessively expanding. As a result, the composite can be prevented from being deformed.

[0048] (ITEM 7)

[0049] The method for manufacturing the absorbent article for pets according to any one of items 1 to 6 can include a plurality of elastic members, and can further include a step of applying a hot melt adhesive to the first sheet member along a plurality of application regions that are separated from each other in a short direction perpendicular to the long direction and extend linearly in the long direction before the plurality of attachment regions are attached to the first sheet member, the plurality of elastic members being disposed between the plurality of application regions. In this case, the plurality of elastic members can be appropriately shrunk without being in contact with the plurality of application regions, and as a result, formation of unnecessary stretch regions can be suppressed. In addition, the first sheet member and the second sheet member can be firmly joined to each other by the plurality of application regions that extend linearly.

[0050] Item 8

[0051] In the method of manufacturing the absorbent article for pets according to any one of items 7 to 10, the plurality of slits can be formed so as to extend in a direction oblique with respect to the longitudinal direction. In this case, the total length of the plurality of slits in the transverse direction is relatively short. Thus, even in the case where the composite is pulled in the longitudinal direction during the manufacturing of the absorbent article for pets, the plurality of slits can be inhibited from being excessively enlarged.

[0052] Item 9

[0053] In the method of manufacturing the absorbent article for pets according to item 8, the plurality of slits can extend in a direction oblique with respect to the longitudinal direction. In this case, the total length of the plurality of slits in the transverse direction is relatively short. Thus, even in the case where the composite is pulled in the longitudinal direction during the manufacturing of the absorbent article for pets, the plurality of slits can be inhibited from being excessively enlarged.

[0054] Item 10

[0055] In the method of manufacturing the absorbent article for pets according to any one of items 8 to 9, the plurality of slits can be formed so as to be spaced apart in the transverse direction. In this case, the total length of the plurality of slits in the transverse direction is relatively short. Thus, even in the case where the composite is pulled in the longitudinal direction during the manufacturing of the absorbent article for pets, the plurality of slits can be inhibited from being excessively enlarged.

[0056] Item 11

[0057] In the method of manufacturing the absorbent article for pets according to any one of items 8 to 10, the plurality of slits can be arranged in a staggered manner when viewed in the thickness direction of the composite. In this case, the plurality of elastic members can be cut efficiently.

[0058] Item 12

[0059] In the method of manufacturing the absorbent article for pets according to any one of items 8 to 11, the plurality of slits can include a first slit and a second slit offset from the first slit in the longitudinal direction, and the first slit can be arranged so as to partially overlap with the second slit in the transverse direction, and the length of the portion of the first slit overlapping with the second slit in the transverse direction can be shorter than the length of the portion of the first slit not overlapping with the second slit in the transverse direction. In this case, by making the length of the portion of the first slit overlapping with the second slit in the transverse direction relatively short, the elastic member can be inhibited from being cut at both positions corresponding to the first slit and the second slit. Thus, the generation of cut pieces (cut residues) of the elastic member can be inhibited.

[0060] Item 13

[0061] One aspect of the present application relates to a pet absorbent article. The pet absorbent article is a pet absorbent article having an oblong shape including a longitudinal direction and a lateral direction, and is worn by being wrapped around a waist of a pet. The pet absorbent article includes a main body portion including a first end edge disposed on one side in the longitudinal direction and a second end edge disposed on the other side in the longitudinal direction, and has a surface sheet disposed on a skin-facing surface side, a back sheet disposed on a non-skin-facing surface side, an absorbent body disposed between the surface sheet and the back sheet, and one or more elastic members that stretch and contract in the longitudinal direction. The main body portion has a high stretch region including the one or more elastic members and providing a contraction force in the longitudinal direction to a portion of the main body portion. A cutout is formed in the main body portion and is disposed on an extension line of the one or more elastic members disposed in the high stretch region between the first end edge and the second end edge.

[0062] In the pet absorbent article according to the above aspect, the main body portion has the high stretch region including the one or more elastic members and providing the contraction force in the longitudinal direction to the portion of the main body portion. Thus, the stretchability is imparted to the pet absorbent article locally. In the pet absorbent article, the cutout is disposed on the extension line of the one or more elastic members disposed in the high stretch region between the first end edge and the second end edge. Thus, for example, the manufacturing method of the pet absorbent article described above can be employed. Thus, in the pet absorbent article, the stretchability is easily imparted to the desired region (the portion of the main body portion described above) of the pet absorbent article.

[0063] Item 14

[0064] In the pet absorbent article according to Item 13, the cutout can include one or more slits extending in a direction inclined with respect to the longitudinal direction. In this case, the total length of the one or more slits in the lateral direction is relatively short. Thus, even in a case where the main body portion is pulled in the longitudinal direction, for example, at the time of wearing the pet absorbent article, the one or more slits can be inhibited from being excessively enlarged.

[0065] Item 15

[0066] In the pet absorbent article according to Item 13 or 14, the cutout can include a plurality of slits formed at intervals in the lateral direction. In this case, the total length of the plurality of slits in the lateral direction is relatively short. Thus, even in a case where the main body portion is pulled in the longitudinal direction, for example, at the time of wearing the pet absorbent article, the plurality of slits can be inhibited from being excessively enlarged.

[0067] Item 16

[0068] In the absorbent article for pets according to item 15, the plurality of slits can be arranged in a staggered manner when viewed in the thickness direction of the main body portion. In this case, the plurality of elastic members can be efficiently cut during the manufacturing process of the absorbent article for pets.

[0069] (ITEM 17)

[0070] In the absorbent article for pets according to any one of items 13 to 16, the main body portion can further include a cover sheet arranged between the back sheet and the absorbent body, and the cutout can be formed in at least one of the cover sheet and the back sheet. In this case, a manufacturing method in which the elastic member is cut from the side of at least one of the cover sheet and the back sheet can be employed.

[0071] (ITEM 18)

[0072] In the absorbent article for pets according to item 17, the cutout can be covered from the skin side by the surface sheet. In this case, it is possible to suppress a deterioration in the skin feel when the absorbent article for pets is worn.

[0073] (ITEM 19)

[0074] In the absorbent article for pets according to any one of items 13 to 18, the cutout can be formed between the absorbent body and the second end edge when viewed in the thickness direction of the main body portion. In this case, it is possible to suppress leakage of urine discharged to the absorbent body through the cutout.

[0075] (ITEM 20)

[0076] In the absorbent article for pets according to any one of items 13 to 19, the high stretch region can be formed between the first end edge and the absorbent body when viewed in the thickness direction of the main body portion. In this case, it is possible to effectively absorb urine in the absorbent body without easily causing wrinkles in the absorbent body due to contraction of the high stretch region.

[0077] (ITEM 21)

[0078] One method involves manufacturing a pet absorbent article for wearing around a pet's waist, comprising: a step of preparing a first strip-shaped component extending in the longitudinal direction; a step of intermittently applying a hot melt adhesive to the first strip-shaped component to form a plurality of adhesive areas spaced apart in the longitudinal direction on the first strip-shaped component, such that one or more elastic members are extended in the longitudinal direction, and then bonding one or more elastic members to the plurality of adhesive areas on the first strip-shaped component; a step of layering a second strip-shaped component extending in the longitudinal direction on the first strip-shaped component with the one or more elastic members in between, forming a composite comprising the first strip-shaped component, one or more elastic members, and the second strip-shaped component; and a step of cutting slits in the composite from the side of the first strip-shaped component or the side of the second strip-shaped component to cut one or more elastic members between the plurality of adhesive areas, causing one or more elastic members to contract between the plurality of adhesive areas, thereby forming a plurality of highly elastic areas spaced apart in the longitudinal direction in the composite.

[0079] In the manufacturing method of the pet absorbent article described above, a hot melt adhesive is intermittently applied to a first component, forming multiple bonding areas spaced apart along the long side of the first component. Furthermore, an elastic member is cut between the multiple bonding areas, forming multiple highly elastic regions spaced apart along the long side of the composite. That is, in this manufacturing method, the areas coated with hot melt adhesive become highly elastic regions. According to this manufacturing method, the position of the highly elastic regions can be controlled based on the application position of the hot melt adhesive, thus easily imparting elasticity to desired areas of the pet absorbent article.

[0081] The following is a reference to the appendix. Figure 1 The embodiments of this application will be described in detail below. In the description of the drawings, the same reference numerals are used to refer to the same elements, and repeated descriptions are omitted. Sometimes, parts of the drawings are simplified or exaggerated for ease of understanding, and the size ratios are not limited to those shown in the drawings.

[0082] The following describes an absorbent article for pets according to one embodiment. Figure 1 This is a top view of the pet absorbent product 1 viewed from the skin side Z1. Figure 2 This is a top view of the pet absorbent item 1 viewed from the non-skin side Z2. Figure 3 It is along Figure 1 A cross-sectional view of AA-lined absorbent pet item 1. Figure 4 It is along Figure 1 A cross-sectional view of BB line pet absorbent item 1. Figures 1-4The illustrated pet absorbent article 1 is a pet disposable diaper that absorbs urine of a pet.

[0083] Figures 1-4 The pet absorbent article 1 in an extended state is shown. The extended state means that the pet absorbent article 1 is elongated to a state where no wrinkles are formed. In contrast, the natural state means a state where no external force is applied to the pet absorbent article 1. The skin side Z1 means a side facing the skin surface of a pet when the pet absorbent article 1 is in a worn state. The non-skin side Z2 means a side facing the opposite side of the skin surface of the pet when the pet absorbent article 1 is in the worn state. In the following description, a person who wears the pet absorbent article 1 to a pet will be referred to as a "user". Typically, the user is a pet keeper. In the following description, the positional relationship in the extended state will be described unless otherwise specified.

[0084] In the present specification, a pet broadly includes vertebrates, invertebrates, and typically, includes pet animals such as dogs, cats, rabbits, hamsters, and the like. The pet absorbent article 1 is particularly suitable for use on a male pet whose urethral opening is located forward of the root of the hind leg. As shown, Figure 1 The pet absorbent article 1 extends in a short side direction X disposed along the front-to-rear direction of a pet (the direction connecting the head and the hip) and in a long side direction Y disposed along the waist direction of the pet. The short side direction X and the long side direction Y are perpendicular to each other. The thickness direction Z is perpendicular to the short side direction X and the long side direction Y, and includes the skin side Z1 facing the skin surface of the pet in the worn state and the non-skin side Z2 facing the opposite side of the skin surface of the pet in the worn state. The pet absorbent article 1 is worn by being wrapped around the waist of the pet.

[0085] The pet absorbent article 1 has a main body portion 2. The main body portion 2 has a planar shape of a substantially rectangular shape (a transversely long shape) having a short side direction X and a long side direction Y. The four corners of the main body portion 2 are cut in a manner that the width of the main body portion 2 in the short side direction X narrows. Alternatively, the four corners of the main body portion 2 can not be cut. The main body portion 2 has a front end edge 3 disposed on one end side in the short side direction X and a rear end edge 4 disposed on the other end side in the short side direction X. When the pet absorbent article 1 is worn on a pet, the front end edge 3 is disposed on the front leg side of the pet, and the rear end edge 4 is disposed on the rear leg side of the pet. In the following description, the direction from the rear end edge 4 to the front end edge 3 will be referred to as the front side, and the direction from the front end edge 3 to the rear end edge 4 will be referred to as the rear side. In addition, the main body portion 2 has a first end edge 5 disposed on one end side in the long side direction Y and a second end edge 6 disposed on the other end side in the long side direction Y.

[0086] The main body 2 has a first portion 2A disposed on one side in the longitudinal direction Y with respect to a center line P of the main body 2 in the longitudinal direction Y, and a second portion 2B disposed on the other side in the longitudinal direction Y with respect to the center line P of the main body 2 in the longitudinal direction Y. The first portion 2A is a region between the center line P and the first end edge 5, and the second portion 2B is a region between the center line P and the second end edge 6.

[0087] As shown in Figures 1-4 , the main body 2 includes a surface sheet 10, a back sheet 20, and an absorbent body 30. The surface sheet 10 constitutes a surface that comes into contact with a pet in the main body 2, and is disposed on the skin side Z1. The surface sheet 10 has, for example, liquid permeability that allows the urine of the pet to pass through to the absorbent body 30 side. The surface sheet 10 is located substantially in the center in the short direction X. As shown in Figure 3 and Figure 4 , the surface sheet 10 is joined to the back sheet 20, the absorbent body 30, and a cover sheet 70 by a hot melt adhesive H1. As the nonwoven fabric constituting the surface sheet 10, a thermofixed nonwoven fabric, a spunbond nonwoven fabric, or a point-bonded nonwoven fabric, or the like can be exemplified.

[0088] The back sheet 20 constitutes a surface that is located on the outside when worn in the main body 2, and is disposed on the non-skin side Z2. The back sheet 20 includes a liquid-impermeable back film 21 and a back nonwoven fabric 22 disposed on the non-skin side Z2 side than the back film 21. The back film 21 has a width substantially the same as the width of the back nonwoven fabric 22. The back nonwoven fabric 22 constitutes the outermost layer of the pet absorbent article 1. As the nonwoven fabric constituting the back nonwoven fabric 22, a thermofixed nonwoven fabric, a spunbond nonwoven fabric, or a point-bonded nonwoven fabric, or the like can be exemplified. The back film 21 is joined to the back nonwoven fabric 22 by a hot melt adhesive H2.

[0089] As shown in Figure 3 , the absorbent body 30 is disposed between the surface sheet 10 and the back sheet 20, and is joined to the cover sheet 70 by a hot melt adhesive H6. The absorbent body 30 is located substantially in the center of the main body 2, and functions to absorb the urine of the pet. The absorbent body 30 has a substantially rectangular shape extending in the longitudinal direction Y. The absorbent body 30 includes an absorbent core 31 and a core cover 32. The absorbent core 31 includes pulp having water absorbency and a high molecular absorbent (SAP). As the pulp, for example, chemical pulp, cellulose fiber, rayon fiber, acetate fiber, or the like can be used. As the high molecular absorbent, for example, a granular or fibrous polymer of starch-based, acrylic acid-based, or amino acid-based can be used. The core cover 32 covers the surface of the absorbent core 31, and is joined to the absorbent core 31 by a hot melt adhesive H3. In addition, the absorbent body 30 can also be an SAP sheet that is constituted mainly of SAP without including pulp.

[0090] As shown in Figure 1As shown, the main body portion 2 includes a first end portion 7 disposed on one side in the longitudinal direction Y and a second end portion 8 disposed on the other side in the longitudinal direction Y. In one embodiment, the first end portion 7 is a region between the absorbent body 30 and the first end edge 5 in the longitudinal direction Y. The second end portion 8 is a region between the absorbent body 30 and the second end edge 6 in the longitudinal direction Y. The first end portion 7 is part of the first portion 2A, and the second end portion 8 is part of the second portion 2B.

[0091] The pet absorbent article 1 also includes a pair of leakage barrier gathers 40. The pair of leakage barrier gathers 40 are provided on the surface sheet 10 and are disposed apart from each other in the lateral direction X. The pair of leakage barrier gathers 40 are disposed so as to cover both side portions in the lateral direction X of the surface sheet 10 from the skin surface side Zl and extend in the longitudinal direction Y over the entire length of the main body portion 2 in the longitudinal direction Y. The pair of leakage barrier gathers 40 suppress leakage in the lateral direction X of urine of the pet discharged to the absorbent body 30 by standing up with respect to the surface sheet 10.

[0092] The pair of leakage barrier gathers 40 includes a front side leakage barrier gather 41 provided along the front end edge 3 and a rear side leakage barrier gather 51 provided along the rear end edge 4. As shown in Figure 3 and Figure 4 shown, the front side leakage barrier gather 41 and the rear side leakage barrier gather 51 are locally joined to the surface sheet 10 by a hot melt adhesive H4 and locally joined to the back sheet 20 by a hot melt adhesive H5. In Figure 3 and Figure 4 In the example shown, the pair of leakage barrier gathers 40 are configured as separate members from other members, but in one embodiment, the pair of leakage barrier gathers 40 can be formed by folding the back nonwoven fabric 22 to the surface sheet 10 side outside the main body portion 2 in the lateral direction X. In this case, part of the back nonwoven fabric 22 folded to the surface sheet 10 side constitutes the pair of leakage barrier gathers 40, and the other part of the back nonwoven fabric 22 constitutes the back sheet 20 of the main body portion 2.

[0093] The front side leakage barrier gather 41 includes a front side leakage barrier sheet 42 and an elastic member 43 disposed along an inner side edge 42a of the front side leakage barrier sheet 42 in the lateral direction X. The front side leakage barrier sheet 42 is disposed on one side (the front end edge 3 side) in the lateral direction X. The rear side leakage barrier gather 51 includes a rear side leakage barrier sheet 52 and an elastic member 53 disposed along an inner side edge 52a of the rear side leakage barrier sheet 52 in the lateral direction X. The rear side leakage barrier sheet 52 is disposed on the other side (the rear end edge 4 side) in the lateral direction X. The front side leakage barrier sheet 42 and the rear side leakage barrier sheet 52 are each configured from a nonwoven fabric having water repellency or hydrophobicity. For example, the front side leakage barrier sheet 42 and the rear side leakage barrier sheet 52 are configured from a spunlace nonwoven fabric, a spunbond nonwoven fabric, a thermal bonded nonwoven fabric, a meltblown nonwoven fabric, an SMS nonwoven fabric, a needle punch nonwoven fabric, a thermofixed nonwoven fabric, or the like.

[0094] InFigure 1 In the drawing, for the sake of convenience of explanation, the regions of the front leakage preventing sheet 42 and the rear leakage preventing sheet 52 that are joined to the surface sheet 10 are shown in hatching. The front leakage preventing sheet 42 includes a lateral fixing portion 44, a first longitudinal fixing portion 45, a second longitudinal fixing portion 46, and a front standing portion 47. The lateral fixing portion 44, the first longitudinal fixing portion 45, and the second longitudinal fixing portion 46 are regions of the front leakage preventing sheet 42 that are joined to the surface sheet 10. The front standing portion 47 is a region of the front leakage preventing sheet 42 that is not joined to the surface sheet 10.

[0095] The lateral fixing portion 44 is disposed on one side (the front end edge 3 side) in the short edge direction X with respect to the absorbent body 30, and extends along the long edge direction Y. A front standing line 44a that is a standing fulcrum of the front standing portion 47 in the short edge direction X is formed at the boundary between the lateral fixing portion 44 and the front standing portion 47.

[0096] The first longitudinal fixing portion 45 is disposed on one side (the first end edge 5 side) in the long edge direction Y, and is joined to the main body portion 2 in a state of falling toward the inside in the short edge direction X. A standing line 45a that is a standing fulcrum of the front standing portion 47 in the long edge direction Y is formed at the boundary between the first longitudinal fixing portion 45 and the front standing portion 47.

[0097] The second longitudinal fixing portion 46 is disposed on the other side (the second end edge 6 side) in the long edge direction Y, and is joined to the main body portion 2 in a state of falling toward the inside in the short edge direction X. A standing line 46a that is a standing fulcrum of the front standing portion 47 in the long edge direction Y is formed at the boundary between the second longitudinal fixing portion 46 and the front standing portion 47.

[0098] The first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 are disposed separately from the lateral fixing portion 44 toward the inside in the short edge direction X. The first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 partially overlap the absorbent body 30 when viewed in the thickness direction Z. Alternatively, the first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 can not overlap the absorbent body 30 when viewed in the thickness direction Z. The first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 are joined to the surface sheet 10 by a hot melt adhesive H4 (see FIG. 2) respectively. Figure 3 and Figure 4

[0099] The front standing portion 47 is disposed between the first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 on the inside of the front standing line 44a in the short edge direction X, and is a region that is not joined to the main body portion 2. The front standing portion 47 is capable of standing along the front standing line 44a. Further, since the first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 of the front leakage preventing sheet 42 are joined to the main body portion 2, the front standing portion 47 falls toward the inside in the short edge direction X in the unfolded state as shown in FIG. 2. Figure 3 The front standing portion 47 is disposed between the first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 on the inside of the front standing line 44a in the short edge direction X, and is a region that is not joined to the main body portion 2. The front standing portion 47 is capable of standing along the front standing line 44a. Further, since the first longitudinal fixing portion 45 and the second longitudinal fixing portion 46 of the front leakage preventing sheet 42 are joined to the main body portion 2, the front standing portion 47 falls toward the inside in the short edge direction X in the unfolded state as shown in FIG. 2.​

[0100] As shown in Figure 3 Fig. 6, the inner side portions of the front side leakage preventing sheets 42 in the short side direction X are partially folded toward the non-skin side Z2, and the elastic members 43 are arranged between the folded front side leakage preventing sheets 42. The elastic members 43 are composed of, for example, a stretchable material such as rubber or spandex which can be contracted in the long side direction Y.

[0101] The elastic members 43 are joined to the front side leakage preventing sheets 42 by a hot melt adhesive in a state of being elongated in the long side direction Y. Thus, when the elastic members 43 are contracted in the long side direction Y, the front side standing portions 47 are contracted in the long side direction Y together with the elastic members 43. As a result, the front side standing portions 47 stand along the front side standing lines 44a on the outside of the short side direction X of the absorbent body 30. By the front side standing portions 47 standing, leakage of urine of the pet along the surface of the surface sheet 10 to the front side is prevented.

[0102] The rear side leakage preventing sheet 52 of the rear side leakage preventing gather 51 includes a lateral fixing portion 54, a first longitudinal fixing portion 55, a second longitudinal fixing portion 56, and a rear side standing portion 57. The lateral fixing portion 54, the first longitudinal fixing portion 55, and the second longitudinal fixing portion 56 are regions of the rear side leakage preventing sheet 52 which are joined to the surface sheet 10. The rear side standing portion 57 is a region of the rear side leakage preventing sheet 52 which is not joined to the surface sheet 10.

[0103] The lateral fixing portion 54 is arranged on the other side (the rear end edge 4 side) of the short side direction X with respect to the absorbent body 30 and extends along the long side direction Y. A rear side standing line 54a which becomes a standing fulcrum of the rear side standing portion 57 in the short side direction X is formed at the boundary between the lateral fixing portion 54 and the rear side standing portion 57.

[0104] The first longitudinal fixing portion 55 is arranged on the one side (the first end edge 5 side) of the long side direction Y and is joined to the main body portion 2 in a state of falling toward the inside of the short side direction X. A standing line 55a which becomes a standing fulcrum of the rear side standing portion 57 in the long side direction Y is formed at the boundary between the first longitudinal fixing portion 55 and the rear side standing portion 57.

[0105] The second longitudinal fixing portion 56 is arranged on the other side (the second end edge 6 side) of the long side direction Y and is joined to the main body portion 2 in a state of falling toward the inside of the short side direction X. A standing line 56a which becomes a standing fulcrum of the rear side standing portion 57 in the long side direction Y is formed at the boundary between the second longitudinal fixing portion 56 and the rear side standing portion 57.

[0106] The first longitudinal fixing portion 55 and the second longitudinal fixing portion 56 are arranged separately from the transverse fixing portion 54 in the short side direction X. The first longitudinal fixing portion 55 and the second longitudinal fixing portion 56 do not overlap with the absorber 30 when viewed from the thickness direction Z. However, the first longitudinal fixing portion 55 and the second longitudinal fixing portion 56 may also partially overlap with the absorber 30 when viewed from the thickness direction Z. The first longitudinal fixing portion 55 and the second longitudinal fixing portion 56 are respectively bonded by hot melt adhesive H4 (see reference). Figure 3 and Figure 4 And it is bonded to the surface sheet 10.

[0107] The rear upright portion 57 is disposed inside the rear upright line 54a in the short side direction X, between the first longitudinal fixing portion 55 and the second longitudinal fixing portion 56, and is a non-joined area relative to the main body portion 2. The rear upright portion 57 can be erected along the rear upright line 54a. Furthermore, since the first longitudinal fixing portion 55 and the second longitudinal fixing portion 56 of the rear leak-proof sheet 52 are joined to the main body portion 2, therefore... Figure 3 As shown, the rear upright portion 57 falls inward toward the short side X when in the unfolded state.

[0108] like Figure 3 As shown, a portion of the inner side of the rear leak-proof sheet 52 in the short side direction X is partially folded towards the non-skin side side Z2, and an elastic member 53 is disposed between the folded rear leak-proof sheets 52. The elastic member 53 is made of, for example, a stretchable material such as rubber or spandex that can contract in the long side direction Y.

[0109] The elastic member 53 is joined to the rear leak-proof sheet 52 in an elongated state in the long side direction Y by a hot-melt adhesive. Therefore, when the elastic member 53 contracts in the long side direction Y, the rear upright portion 57 contracts together with the elastic member 53 in the long side direction Y. As a result, the rear upright portion 57 stands upright along the rear upright line 54a on the outer side of the absorbent body 30 in the short side direction X. The upright position of the rear upright portion 57 prevents pet urine from moving along the surface of the surface sheet 10 and leaking rearward.

[0110] The pet absorbent material 1 also includes an outer elastic member 61, an outer elastic member 62, multiple inner elastic members 63, and a cover sheet 70. The outer elastic members 61, 62, and 63 are made of elastic materials such as rubber, stretchable nonwoven fabric, stretchable membrane, or spandex, and are capable of stretching and contracting in the long side direction Y. Furthermore, the number of outer elastic members 61, 62, and 63 can be two or more. The outer elastic members 61, 62, and 63 stretch and contract in accordance with changes in the pet's body shape and posture in the long side direction Y (e.g., the pet's body twisting movements).

[0111] An outer elastic member 61 is disposed between the front upright line 44a and the front edge 3 in the short side direction X, and extends in the long side direction Y. The outer elastic member 61 is disposed between the front leak-proof pleat 41 and the back panel 20. The outer elastic member 61 is joined to the front leak-proof sheet 42 and the back panel 20 by a hot melt adhesive in an elongated state in the long side direction Y.

[0112] An outer elastic member 62 is disposed between the rear upright line 54a and the rear end edge 4 in the short side direction X, and extends in the long side direction Y. The outer elastic member 62 is disposed between the rear leak-proof pleat 51 and the back panel 20. The outer elastic member 62 is joined to the rear leak-proof panel 52 and the back panel 20 by a hot melt adhesive in an elongated state in the long side direction Y.

[0113] The cover sheet 70 is a sheet that fixes multiple inner elastic members 63. The cover sheet 70 is made of nonwoven fabric such as hot-air nonwoven fabric, spunbond nonwoven fabric, or dot-bonded nonwoven fabric. The cover sheet 70 extends along the entire length of the main body 2 in the long side direction Y. The cover sheet 70 is disposed between the back sheet 20 (back film 21) and the absorbent 30. The cover sheet 70 is bonded to the back film 21 by a hot melt adhesive H10. The hot melt adhesive H10 is coated along multiple coating areas CR that are separated from each other in the short side direction X and extend linearly in the long side direction Y. Thus, a space for arranging the inner elastic members 63 is formed between adjacent hot melt adhesives H10.

[0114] The main body 2 includes a highly elastic region HR, which serves as a region providing contractile force in the long-side direction Y. The highly elastic region HR is positioned so as not to overlap with the absorber 30 when viewed from the thickness direction Z. More specifically, the highly elastic region HR is located at the first end 7 of the main body 2. The highly elastic region HR includes a plurality of inner elastic members 63 that provide elastic force in the long-side direction Y. The plurality of inner elastic members 63 are disposed in the short-side direction X between the front upright line 44a and the rear upright line 54a, giving the main body 2 elasticity. In one embodiment, the plurality of inner elastic members 63 are disposed at the first end 7 of the main body 2. More specifically, when viewed from the thickness direction Z, the plurality of inner elastic members 63 extend linearly in the long-side direction Y between the absorber 30 and the engaging member 80 described later.

[0115] Multiple inner elastic members 63 are arranged along the short side between the front upright line 44a and the rear upright line 54a. For example... Figure 4 As shown, the inner elastic member 63 extends in the long side direction Y between adjacent hot melt adhesive H10 (coating area CR). The inner elastic member 63 is disposed between the cover sheet 70 and the back film 21 and is bonded to the cover sheet 70 by hot melt adhesive in an elongated state in the long side direction Y.

[0116] The pet absorbent article 1 further includes an engaging member 80. The engaging member 80 is a member that engages the first portion 2A and the second portion 2B. As shown in Figure 1 The engaging member 80 has an oblong shape that is longer in the short direction X and is provided to the first end portion 7 of the first portion 2A. The engaging member 80 is provided to the surface of the surface sheet 10. The engaging member 80 is, for example, a hook-and-loop fastener having a plurality of hooks and is capable of engaging the back sheet 20 of the second portion 2B from the non-skin surface side Z2. Further, the engaging member 80 can also engage the surface sheet 10 in the second portion 2B. That is, a part of the surface sheet 10 in the first portion 2A and another part of the surface sheet 10 in the second portion 2B can also be engaged.

[0117] In one embodiment, a target member 81 is provided to the outer surface of the back sheet 20 of the second portion 2B. As shown in Figure 2 The target member 81 is, for example, a hook-and-loop fastener having a plurality of loops that engage the plurality of hooks of the engaging member 80 and has an oblong shape that is longer in the long direction Y. In the wearing of the pet absorbent article 1, the engaging member 80 engages the back sheet 20 via the target member 81 provided to the back sheet 20. Further, the engaging member 80 can also directly engage the back sheet 20.

[0118] The pet absorbent article 1 further includes an indicator 90 that changes color in response to urine of a pet. The indicator 90 is formed of, for example, a hot melt adhesive. The indicator 90 is disposed, for example, between the absorbent body 30 and the cover sheet 70. The indicator 90 extends along the long direction Y in the center of the main body 2 in the short direction X.

[0119] As shown in Figure 1 and Figure 2 A plurality of first slits SL1 and a plurality of second slits SL2 are formed in the main body 2. The first slits SL1 and the second slits SL2 are elongated cuts formed in the main body 2 when the inner elastic member 63 is cut and shrunk in the manufacturing method of the pet absorbent article 1. Therefore, the plurality of first slits SL1 and the plurality of second slits SL2 are respectively disposed on the extension lines of the plurality of inner elastic members 63 disposed in the high stretch region HR between the first end edge 5 and the second end edge 6.

[0120] The first slits SL1 and the second slits SL2 are formed between the absorbent body 30 and the second end edge 6. That is, the first slits SL1 and the second slits SL2 are formed in the second end portion 8. In this case, it is possible to suppress leakage of urine discharged to the absorbent body 30 via the first slits SL1 and the second slits SL2. The first slits SL1 and the second slits SL2 are covered from the non-skin surface side Z2 by the target member 81 provided to the second portion 2B.

[0121] The plurality of first slits SL1 and the plurality of second slits SL2 are formed at intervals in the short direction X. In this case, the total length (total of the lengths of the slits) of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the short direction X is relatively short. Thus, even in a case where the main body portion 2 is pulled in the long direction Y, for example, at the time of wearing of the absorbent article 1 for pets, it is possible to suppress the first slits SL1 and the second slits SL2 from being excessively enlarged.

[0122] The second slits SL2 are offset from the first slits SL1 in the long direction Y. Specifically, the first slits SL1 are arranged at intervals on the side of the second end edge 6 with respect to the second slits SL2.

[0123] The first slits SL1 and the second slits SL2 can be formed only in the back sheet 20, only in the cover sheet 70, or throughout the back sheet 20 and the cover sheet 70. In one embodiment, the first slits SL1 and the second slits SL2 are not formed in the surface sheet 10, and the surface sheet 10 covers the skin side Z1. In this case, it is possible to suppress a deterioration in the skin feel at the time of wearing of the absorbent article 1 for pets.

[0124] FIGS. 5(a) and 5(b) are plan views illustrating examples of the arrangement of the first slits SL1 and the second slits SL2. FIGS. 5(a) and 5(b) correspond to enlarged views of the partial regions of the absorbent article 1 for pets illustrated in FIGS. 4(a) and 4(b), respectively. Figure 1 The plurality of first slits SL1 and the plurality of second slits SL2 are formed at intervals in the short direction X. In this case, the total length (total of the lengths of the slits) of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the short direction X is relatively short. Thus, even in a case where the main body portion 2 is pulled in the long direction Y, for example, at the time of wearing of the absorbent article 1 for pets, it is possible to suppress the first slits SL1 and the second slits SL2 from being excessively enlarged.

[0125] In one embodiment, the first slits SL1 and the second slits SL2 extend in directions inclined with respect to the long direction Y, respectively. In this case, the total length (total of the lengths of the slits) of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the short direction X is relatively short. Thus, even in a case where the main body portion 2 is pulled in the long direction Y, for example, at the time of wearing of the absorbent article 1 for pets, it is possible to suppress the first slits SL1 and the second slits SL2 from being excessively enlarged. In the examples of FIGS. 5(a) and 5(b), the first slits SL1 and the second slits SL2 extend in directions inclined by the same angle with respect to the long direction Y.

[0126] As shown in Figure 5(a), in the short side direction X, the first slit SL1 can be positioned in a location that does not overlap with the second slit SL2. That is, the first slit SL1 can be positioned in the short side direction X between two adjacent second slits SL2. The length of the first slit SL1 in the direction extending (the inclined direction) along the first slit SL1 can be substantially the same as the length of the second slit SL2 in the direction extending (the inclined direction) along the second slit SL2.

[0127] As shown in Figure 5(b), in the short-side direction X, the first slit SL1 can also be positioned to partially overlap with the second slit SL2. The length of the portion of the first slit SL1 overlapping with the second slit SL2 in the short-side direction X can be shorter than the length of the portion of the first slit SL1 not overlapping with the second slit SL2 in the short-side direction X. In the example of Figure 5(b), both ends of a certain first slit SL1 overlap with two adjacent second slits SL2. If the lengths of the portions of the first slit SL1 overlapping with the two second slits SL2 in the short-side direction X are respectively defined as lengths L11 and L12, and the length of the portion of the first slit SL1 not overlapping with the second slit SL2 in the short-side direction X is defined as length L2, then the sum of lengths L11 and L12 can be shorter than length L2.

[0128] As shown in Figure 5(b), the lengths of the first slit SL1 extending in the direction of the first slit SL1 (the inclined direction) and the second slit SL2 extending in the direction of the second slit SL2 (the inclined direction) can also be different from each other. As an example, the length of the first slit SL1 can also be longer than the length of the second slit SL2.

[0129] Next, refer to Figure 6 The steps for putting the pet absorbent item 1 on the pet will be explained. Figure 6 This diagram illustrates the steps of putting the pet absorbent item 1 on a pet. First, the user places the second end 8 of the pet absorbent item 1 against the pet's back and holds the area near the second end 8 with one hand. Next, the user holds the first end 7 of the pet absorbent item 1 with their other hand and wraps the pet absorbent item 1 around the pet's abdomen. At this time, the pet absorbent item 1 is put on with the front leak-proof pleat 41 positioned in front of the pet's urethra and the rear leak-proof pleat 51 positioned behind the pet's urethra. Next, the user lifts the first end 7 upwards, so that the engaging member 80 of the first end 7 engages with the target member 81, ensuring the pet absorbent item 1 is snugly placed against the pet's waist.

[0130] Next, the manufacturing method of the pet absorbent article 1 will be described with reference to Figures 7-10 . Figure 7 is a flowchart showing the manufacturing method of the pet absorbent article 1 according to an embodiment. Figure 8 and Figure 9 is a view schematically showing an example of a manufacturing apparatus to which the manufacturing method of the pet absorbent article 1 is applied. Figure 10 is a plan view showing a complex before being divided into a plurality of pet absorbent articles 1. The manufacturing method of the pet absorbent article 1 continuously manufactures the pet absorbent article 1 described above by performing each process described later. In the following description, the terms "upstream" and "downstream" are used with reference to the conveyance direction CD described later.

[0131] As shown in Figure 8 , the manufacturing apparatus 100 includes an elastic member supply apparatus 102, a second sheet member supply apparatus 104, a cutting apparatus 106, and a joint sheet supply apparatus 108.

[0132] In the manufacturing method of the pet absorbent article 1 according to an embodiment, first, the first sheet member 270, the second sheet member 220, and the third sheet member 210 are prepared (step ST1). The first sheet member 270 is a belt-shaped sheet member in which the cover sheet 70 is continuous in the longitudinal direction Y. The second sheet member 220 is a belt-shaped sheet member in which the back sheet 20 is continuous in the longitudinal direction Y. The second sheet member 220 is a complex including a belt-shaped sheet member in which the back film 21 is continuous in the longitudinal direction Y and a belt-shaped sheet member in which the back nonwoven fabric 22 is continuous in the longitudinal direction Y. The third sheet member 210 is a belt-shaped sheet member in which the surface sheet 10 is continuous in the longitudinal direction Y. That is, the first sheet member 270 includes a nonwoven fabric layer, the second sheet member 220 includes a resin film layer (back film 21), and the third sheet member 210 includes a nonwoven fabric layer.

[0133] The first sheet member 270, the second sheet member 220, and the third sheet member 210 are conveyed in the conveyance direction CD, for example, by the conveyance rollers 112 as shown in Figure 9 . The conveyance direction CD is a direction along the longitudinal direction Y of the pet absorbent article 1. In the third sheet member 210, a plurality of engaging members 80 (see Figure 10 ) configured at regular intervals in the conveyance direction CD can also be formed.

[0134] Next, as shown in Figure 8As shown, the first sheet member 270 is coated with the hot melt adhesive H10 (step ST2). The hot melt adhesive H10 is coated by a coating device (not shown) disposed at a position upstream of the elastic member supply device 102, for example. The coating device coats the hot melt adhesive H10 on the first sheet member 270 along a plurality of coating regions CR that are separated from each other in the short side direction X and extend linearly in the conveying direction CD (long side direction Y).

[0135] Next, the elastic member supply device 102 adheres the inner side elastic members 63 to the first sheet member 270 (step ST3). The elastic member supply device 102 intermittently (intermittently) coats the hot melt adhesive among the plurality of inner side elastic members 63 having stretchability. Thus, a plurality of adhesive regions AR are formed in the plurality of inner side elastic members 63 arranged at intervals in the conveying direction CD (long side direction Y). The elastic member supply device 102 adheres the plurality of adhesive regions AR of the plurality of inner side elastic members 63 to the first sheet member 270 in a state in which the plurality of inner side elastic members 63 are elongated in the long side direction Y. At this time, the plurality of inner side elastic members 63 are arranged between the plurality of coating regions CR, respectively.

[0136] Next, the second sheet member supply device 104 stacks the second sheet member 220 on the first sheet member 270 with the plurality of inner side elastic members 63 interposed therebetween. The second sheet member 220 is joined to the first sheet member 270 by the hot melt adhesive H10 (the plurality of coating regions CR). Thus, a composite body 300 including the first sheet member 270, the plurality of inner side elastic members 63, and the second sheet member 220 is formed (step ST4). The composite body 300 is conveyed to the downstream side in the conveying direction CD.

[0137] Next, the cutting device 106 cuts the plurality of inner side elastic members 63 between the plurality of adhesive regions AR by cutting a notch in the composite body 300 from the first sheet member 270 side or the second sheet member 220 side (step ST5). As shown, the cutting device 106 includes a pair of rollers that can rotate. One of the pair of rollers is provided with a cutter (not shown) for cutting the inner side elastic members 63. Figure 8 As shown, the cutting device 106 includes a pair of rollers that can rotate. One of the pair of rollers is provided with a cutter (not shown) for cutting the inner side elastic members 63.

[0138] In a case where the notch is cut in the composite body 300 from the first sheet member 270 side, the plurality of inner side elastic members 63 are cut together with the first sheet member 270. Thus, the first slit SL1 and the second slit SL2 are formed at least in the first sheet member 270. In a case where the notch is cut in the composite body 300 from the second sheet member 220 side, the plurality of inner side elastic members 63 are cut together with the second sheet member 220. Thus, the first slit SL1 and the second slit SL2 are formed at least in the second sheet member 220.

[0139] The cut-off inner elastic member 63 is shrunk in the longitudinal direction Y between the plurality of adhesive regions AR. In other words, the non-adhesive regions of the inner elastic member 63, which are not adhered to the first sheet member 270, are pulled back toward the adhesive regions AR. As a result, in the composite 300, a plurality of high stretch regions HR, which are arranged at intervals in the longitudinal direction Y, are formed. The high stretch regions HR are regions including the adhesive regions AR of the inner elastic member 63.

[0140] Next, the splicing sheet supply device 108 adheres the splicing sheet 281 to the outer surface of the second sheet member 220 (step ST6). As shown in Figure 8 The splicing sheet supply device 108 includes a pair of rollers that can rotate. One of the pair of rollers is formed with a cutter (not shown) for cutting the splicing sheet 281. In one embodiment, the splicing sheet supply device 108 adheres the splicing sheet 281 to the outer surface of the second sheet member 220 with a hot melt adhesive in such a manner that the first slit SL1 and the second slit SL2 are covered from the non-skin surface side. The splicing sheet 281 is cut by the splicing sheet supply device 108 to a predetermined length, thereby forming Figure 2 the target member 81 shown in

[0141] As shown in Figure 9 The manufacturing device 100 further includes a plurality of conveyance rollers 112, elastic member supply devices 114, 116, an absorbent supply device 118, an adhesive device 120, and a cutting device 122. The plurality of conveyance rollers 112 convey the third sheet member 210 and the composite 300 to which the target member 81 is adhered, respectively, to the downstream side in the conveyance direction CD.

[0142] After step ST6, the elastic member supply device 114 fixes the elastic members 43, 53 to the third sheet member 210 (step ST7). The elastic members 43, 53 are fixed to the third sheet member 210 in a state of being elongated in the conveyance direction CD (the longitudinal direction Y). Next, the elastic member supply device 116 fixes the outer elastic members 61, 62 to the second sheet member 220 (step ST8). The outer elastic members 61, 62 are fixed to the second sheet member 220 of the composite 300 in a state of being elongated in the conveyance direction CD (the longitudinal direction Y). The third sheet member 210 to which the elastic members 43, 53 are fixed and the composite 300 to which the outer elastic members 61, 62 are fixed are conveyed to the downstream side in the conveyance direction CD.

[0143] Next, the absorbent supply device 118 arranges a plurality of absorbents 30 on the second sheet member 220 (step ST9). The plurality of absorbents 30 are arranged on the second sheet member 220 at predetermined intervals in the conveyance direction CD. As shown in Figure 10As shown, the absorbers 30 are arranged between the plurality of high stretch regions HR when viewed in the thickness direction (thickness direction Z) of the composite 300.

[0144] More specifically, the absorbers 30 are arranged between the plurality of slits SL and the high stretch regions HR adjacent to the plurality of slits SL among the plurality of high stretch regions HR. In one embodiment, the absorbers 30 are located between the plurality of slits SL and the high stretch regions HR adjacent to the plurality of slits SL on the upstream side in the conveyance direction CD. That is, the high stretch regions HR are arranged on the upstream side in the conveyance direction CD (longitudinal direction Y) with respect to the absorbers 30, and the plurality of slits SL are arranged on the downstream side in the conveyance direction CD (longitudinal direction Y) with respect to the absorbers 30.

[0145] Next, in a state where the second sheet member 220, the first sheet member 270, the plurality of absorbers 30, and the third sheet member 210 are sequentially stacked, the bonding device 120 bonds the composite 300 and the third sheet member 210 using a hot melt adhesive (step ST10). That is, the third sheet member 210 is stacked on the first sheet member 270 with the plurality of absorbers 30 interposed therebetween. The composite 300 is conveyed to the downstream side in the conveyance direction CD in a state where the third sheet member 210 and the plurality of absorbers 30 are stacked.

[0146] Next, the cutting device 122 cuts the composite 300 and the third sheet member 210 along the short edge direction X to produce the pet absorbent article 1 including the composite 300, the absorbers 30, and the third sheet member 210 (step ST11). As shown, the cutting device 122 has a pair of rollers 122A that can rotate and a cutter 122B that cuts the composite 300 and the third sheet member 210. The cutter 122B is attached to the outer circumferential surface of one of the pair of rollers 122A and extends in the axial direction of the roller 122A. The cutter 122B cuts the composite 300 and the third sheet member 210 conveyed by the pair of rollers 122A to divide the composite 300 and the third sheet member 210 into a plurality of pet absorbent articles 1. As a result, a plurality of pet absorbent articles 1 are produced. Figure 9

[0147] Referring to Figure 10 ​The positions at which the composite 300 and the third sheet member 210 are cut will be described. The cutting device 122 cuts the composite 300 and the third sheet member 210 along the cutting line CL located between the slits SL and the high stretch regions HR adjacent to the slits SL. In one embodiment, the cutting line CL is located between the slits SL and the high stretch regions HR on the downstream side in the conveyance direction CD from the slits SL. More specifically, the cutting line CL is located between the slits SL and the engaging members 80. By cutting the composite 300 and the third sheet member 210 at the cutting line CL, the first end edge 5 and the second end edge 6 are formed.

[0148] In the manufacturing method of the absorbent article 1 for pets described above, the hot melt adhesive is intermittently applied to the inner side elastic member 63, and the plurality of adhesive regions AR of the inner side elastic member 63 configured at intervals in the longitudinal direction Y are formed in the first sheet member 270. Also, the inner side elastic member 63 is cut between the plurality of adhesive regions AR, and the plurality of high stretch regions HR configured at intervals in the longitudinal direction Y are formed in the composite 300. That is, in this manufacturing method, the regions to which the hot melt adhesive is applied become the high stretch regions HR. According to this manufacturing method, the positions of the high stretch regions HR can be controlled depending on the positions at which the hot melt adhesive is applied, and thus the stretchability can be easily imparted to the desired regions of the absorbent article 1 for pets.

[0149] As shown in Figure 7 and Figure 9 , the manufacturing method of the absorbent article 1 for pets includes a process (step ST9) of disposing the absorbent body 30 on the first sheet member 270 after the plurality of high stretch regions HR are formed and a process (step ST10) of laminating the third sheet member 210 on the first sheet member 270 with the absorbent body 30 interposed therebetween. In addition, as shown in Figure 10 , the absorbent body 30 is disposed between the plurality of high stretch regions HR when viewed in the thickness direction of the composite 300. In this case, it is possible to prevent the slits SL from being cut in the absorbent body 30 when the slits SL are cut in the composite 300 in order to form the plurality of high stretch regions HR. In addition, since the absorbent body 30 is disposed between the plurality of high stretch regions HR, wrinkles of the absorbent body 30 caused by contraction of the high stretch regions HR are less likely to occur. Thus, it is possible to effectively absorb urine in the absorbent body 30.

[0150] As shown in Figure 10 , the absorbent body 30 is disposed between the plurality of slits SL and the high stretch regions HR adjacent to the plurality of slits SL. In this case, it is possible to suppress leakage of urine discharged to the absorbent body 30 through the slits SL.

[0151] As shown in Figure 7 and Figure 10As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST11) of cutting the composite 300 and the third sheet member 210 between the plurality of slits SL and the high stretch regions HR adjacent to the plurality of slits SL to produce the absorbent article 1 for pets including the composite 300, the absorbent body 30, and the third sheet member 210. In this case, it is possible to produce the appropriate absorbent article 1 for pets without cutting the high stretch regions HR and the slits SL.

[0152] As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST11) of cutting the composite 300 and the third sheet member 210 between the plurality of slits SL and the high stretch regions HR adjacent to the plurality of slits SL to produce the absorbent article 1 for pets including the composite 300, the absorbent body 30, and the third sheet member 210. In this case, it is possible to produce the appropriate absorbent article 1 for pets without cutting the high stretch regions HR and the slits SL. Figure 7 Figure 8 As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST6) of adhering the joining sheet 281 to the outer surface of the second sheet member 220 in a manner of covering the slits SL. In this case, it is possible to suppress some members from being hooked to the slits SL of the composite 300 and causing damage to the composite 300 during the manufacturing process of the absorbent article 1 for pets. In addition, the rigidity of the composite 300 is increased by the joining sheet 281, and it is possible to suppress the slits SL from excessively expanding. As a result, it is possible to suppress the composite 300 from deforming.

[0153] As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST6) of adhering the joining sheet 281 to the outer surface of the second sheet member 220 in a manner of covering the slits SL. In this case, it is possible to suppress some members from being hooked to the slits SL of the composite 300 and causing damage to the composite 300 during the manufacturing process of the absorbent article 1 for pets. In addition, the rigidity of the composite 300 is increased by the joining sheet 281, and it is possible to suppress the slits SL from excessively expanding. As a result, it is possible to suppress the composite 300 from deforming. Figure 7 Figure 8 As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST2) of applying the hot melt adhesive H10 to the first sheet member 270 along the plurality of coating regions CR extending in a linear shape in the longitudinal direction Y while being separated from each other in the lateral direction X before the plurality of adhesive regions AR are adhered to the first sheet member 270, and the plurality of inner elastic members 63 are arranged between the plurality of coating regions CR. In this case, it is possible to appropriately contract the plurality of inner elastic members 63 without contacting the plurality of coating regions CR, and as a result, it is possible to suppress the formation of unnecessary stretch regions. In addition, it is possible to firmly join the first sheet member 270 and the second sheet member 220 to each other using the plurality of coating regions CR extending in a linear shape.

[0154] As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST5) of forming the first slits SL1 and the second slits SL2 in the composite 300 to cut the plurality of inner elastic members 63 from the first sheet member 270 side or the second sheet member 220 side. In this case, it is possible to easily cut the plurality of inner elastic members 63. Figure 7 Figure 8 As shown in FIG. 6, the manufacturing method of the absorbent article 1 for pets includes a step (step ST5) of forming the first slits SL1 and the second slits SL2 in the composite 300 to cut the plurality of inner elastic members 63 from the first sheet member 270 side or the second sheet member 220 side. In this case, it is possible to easily cut the plurality of inner elastic members 63.

[0155] ​​​As shown in FIGS. 5(a) and 5(b), the first slits SL1 and the second slits SL2 can extend in directions inclined with respect to the longitudinal direction Y. In this case, the total length of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the lateral direction X is relatively short. Thus, even if the complex body 300 is pulled in the longitudinal direction Y during the manufacture of the absorbent article for pets 1, the first slits SL1 and the second slits SL2 can be inhibited from being excessively enlarged.

[0156] As shown in FIGS. 5(a) and 5(b), the plurality of first slits SL1 and the plurality of second slits SL2 can be formed at intervals in the lateral direction X. In this case, the total length of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the lateral direction X is relatively short. Thus, even if the complex body 300 is pulled in the longitudinal direction Y during the manufacture of the absorbent article for pets 1, the first slits SL1 and the second slits SL2 can be inhibited from being excessively enlarged.

[0157] As shown in FIGS. 5(a) and 5(b), the plurality of first slits SL1 and the plurality of second slits SL2 can be formed at intervals in the lateral direction X. In this case, the total length of each of the plurality of first slits SL1 and the plurality of second slits SL2 in the lateral direction X is relatively short. Thus, even if the complex body 300 is pulled in the longitudinal direction Y during the manufacture of the absorbent article for pets 1, the first slits SL1 and the second slits SL2 can be inhibited from being excessively enlarged.

[0158] As shown in FIG. 5(b), the length of the portion of the first slit SL1 in the lateral direction X that overlaps the second slit SL2 can be shorter than the length of the portion of the first slit SL1 in the lateral direction X that does not overlap the second slit SL2. By making the length of the portion of the first slit SL1 in the lateral direction X that overlaps the second slit SL2 relatively short, the inner elastic member 63 can be inhibited from being cut at both places corresponding to the first slit SL1 and the second slit SL2. Thus, the generation of cut pieces (cut residues) of the inner elastic member 63 can be inhibited.

[0159] The above-described embodiments of the absorbent article for pets and the method of manufacturing the absorbent article for pets are described, but the present application is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present application. That is, it should be noted that the above-described embodiments are described for the purpose of illustration, and do not limit the scope of the present application.

[0160] In Figure 7In the manufacturing method of the absorbent article for pets shown in the drawing, the plurality of adhesive regions AR arranged at intervals in the longitudinal direction Y are formed in the inner side elastic member 63 in step ST3, but the plurality of adhesive regions AR can also be formed in the first sheet member 270 by intermittently applying the hot melt adhesive to the first sheet member 270. In this case, the inner side elastic member 63 can also be adhered to the plurality of adhesive regions AR of the first sheet member 270 in a state in which the inner side elastic member 63 having stretchability is elongated in the longitudinal direction Y.

[0161] In Figure 7 In the manufacturing method of the absorbent article for pets shown in the drawing, the hot melt adhesive is intermittently applied in step ST3, but the hot melt adhesive can also be continuously applied to the inner side elastic member 63. In this case, in step ST5, a plurality of slits can also be cut out between a plurality of regions in which the complex 300 is arranged at intervals in the longitudinal direction Y from the side of the first sheet member 270 or the side of the second sheet member 220, the inner side elastic member 63 is cut between the plurality of regions, the inner side elastic member 63 is contracted between the plurality of regions, and a plurality of high stretch regions HR arranged at intervals in the longitudinal direction Y are formed in the plurality of regions.

[0162] That is, the manufacturing method of the absorbent article for pets can also be "a manufacturing method of an absorbent article for pets, which is worn by being wrapped around the waist of a pet, the manufacturing method including: a step of preparing a first sheet member in a belt shape extending in a longitudinal direction; a step of continuously applying a hot melt adhesive to one or more elastic members having stretchability to adhere the one or more elastic members to the first sheet member in a state in which the one or more elastic members are elongated in the longitudinal direction; a step of laminating a second sheet member in a belt shape extending in the longitudinal direction on the first sheet member with the one or more elastic members interposed therebetween to form a complex including the first sheet member, the one or more elastic members, and the second sheet member; and a step of cutting a plurality of slits between a plurality of regions in which the complex is arranged at intervals in the longitudinal direction from the side of the first sheet member or the side of the second sheet member to cut the one or more elastic members between the plurality of regions, thereby forming a plurality of high stretch regions arranged at intervals in the longitudinal direction in the plurality of regions". In this case, the hot melt adhesive can also be continuously applied to the first sheet member instead of the one or more elastic members. The various embodiments described above can be combined within a range in which there is no contradiction.
