[0003] Patent Document 1 Japanese Unexamined Patent Application Publication No. 2014-108824 Patent Document 2 Japanese Utility Model Registration No. 3222065 Summary of the Invention Problems to be Solved by the Invention

[0004] The package of Patent Document 1 houses one absorbent article. Therefore, when using a plurality of absorbent articles, it is necessary to carry a plurality of packages. Furthermore, as a result of intensive research conducted by the applicant on the usage modes of pet diapers, pet diapers are not always worn at all times, but may be worn as a matter of etiquette depending on the location. More specifically, pet diapers are worn when bringing a pet to a specific location such as a building. If the pet excretes while wearing the diaper, the pet diaper needs to be replaced. Therefore, it has been necessary to carry a plurality of pet diapers.

[0005] The packaging described in Patent Document 2 contains multiple absorbent articles. However, the volume of the packaging's storage space is larger than the volume of the absorbent articles contained within. As a result, the absorbent articles can shift within the packaging, causing them to deform. In particular, continuous packaging, such as that described in Patent Document 1, in which multiple packaging units are linked together, is displayed by being hung in stores, and users can cut off and purchase the required number of packaging units. Therefore, compared to packaging displayed on shelves, it is more susceptible to external forces, making it easier for the absorbent articles to deform.

[0006] This invention has been made in view of the above-mentioned problems, and aims to maintain the quality of pet diapers in a continuous package consisting of multiple connected packages containing multiple pet diapers. [Means for solving the problem]

[0007] In one embodiment, a continuous packaging consists of multiple continuous packaging units, each containing a pet diaper wrapped in a packaging sheet. Within each individual packaging unit, multiple pet diapers are stacked in the thickness direction. The outer surfaces of adjacent pet diapers in the thickness direction are in contact with each other. [Brief explanation of the drawing]

[Figure 7] This is a diagram illustrating the folding method of a pet diaper according to the second embodiment. [Modes for carrying out the invention]

[0009] (1) Outline of the Embodiment The following matters become clear from this specification and the accompanying drawings: The continuous packaging according to Embodiment 1 consists of multiple continuous packaging units, each containing a pet diaper wrapped in a packaging sheet. Multiple pet diapers are stacked in the thickness direction within each individual packaging unit. The outer surfaces of adjacent pet diapers in the thickness direction are in contact with each other. The outer surfaces of the pet diapers have fine irregularities formed by the surface irregularities of the absorbent core, etc. By having the outer surfaces of adjacent pet diapers in the thickness direction come into contact with each other, displacement of the pet diapers can be suppressed. This suppresses the displacement of individual pet diapers within the packaging unit, and prevents deformation of the outer edges of displaced pet diapers by contact with the inner wall of the packaging unit, as well as deformation of the outer edges of displaced pet diapers by external forces on the packaging unit. In a packaging unit containing multiple pet diapers, deformation of the pet diapers can be suppressed and the quality of the pet diapers can be maintained.

[0010] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1. The continuous packaging body has a first direction in which the packaging bodies are adjacent to each other, and a second direction perpendicular to the first direction. Between adjacent packaging bodies, a packaging joint portion, to which the packaging sheet is joined, extends along the second direction. The pet diaper has a hook sheet provided with a plurality of hook members that join the outer surfaces of opposing pet diapers when worn on a pet. The hook sheet extends along the first direction. According to this embodiment, the rigidity of the continuous packaging body in the second direction can be increased by the packaging joint portion extending along the second direction, and the rigidity of the continuous packaging body in the first direction can be increased by the hook sheet extending along the first direction. Therefore, the rigidity of the continuous packaging body in both the first and second directions can be increased, and deformation of the pet diaper contained inside can be suppressed.

[0011] In a preferred embodiment, the invention according to Embodiment 3 may have the following features in the invention according to Embodiment 2: The pet diaper is housed in the packaging in a folded state, folded with respect to the folds. The length of the hook sheet in the first direction is 80% or more of the length of the pet diaper in the first direction in the folded state. According to this embodiment, the rigidity can be increased by the hook sheet in a range of 80% or more of the length of the pet diaper in the first direction in the folded state, and deformation of the pet diaper in the first direction in the folded state can be effectively suppressed.

[0012] In a preferred embodiment, the invention according to Embodiment 4 may have the following features in the invention according to Embodiment 2 or Embodiment 3: The hook members of the hook sheet engage with the outer surfaces of adjacent pet diapers in the thickness direction. According to this embodiment, the engagement of the hook members with adjacent diapers makes it difficult for the relative positions of adjacent diapers to shift within the packaging. Therefore, friction between the outer surfaces of the diapers is suppressed, and fraying of the outer sheet is suppressed.

[0013] In a preferred embodiment, the invention according to Embodiment 5 may have the following features in the invention according to Embodiment 1. The pet diaper is housed in the packaging in a folded state, folded with respect to a fold. The continuous packaging has a first direction in which the packaging bodies are adjacent to each other, and a second direction perpendicular to the first direction. The pet diaper has a hook sheet provided with a plurality of hook members that join the outer surfaces of opposing pet diapers when worn on a pet. The hook sheets are arranged in the folded state with spacing between them in the second direction. According to this embodiment, the spacing between the hook sheets in the second direction acts as a buffer area, partially absorbing deformation in the second direction and suppressing deformation of the entire pet diaper in the second direction.

[0014] In a preferred embodiment, the invention according to Embodiment 6 may have the following features in the invention according to any of Embodiments 1 to 5. The pet diaper is housed in the packaging in a folded state, folded with respect to a fold. In the folded state, a contracted portion is formed outside the outer edge of the absorbent core by an elastic member. According to this embodiment, the contracted portion can alleviate the force acting on the outer edge of the absorbent core and suppress deformation of the absorbent core.

[0015] In a preferred embodiment, the invention according to embodiment 7 may have the following features in the invention according to embodiment 6. The continuous packaging body has a first direction in which the packaging bodies are adjacent to each other, and a second direction perpendicular to the first direction. The shrinking portion is provided along the second direction at the end of the pet diaper in the first direction when it is folded. The end of the pet diaper in the first direction is likely to be located near the packaging joint and is a part that is easily subjected to force by being grasped or twisted when separating the packaging joint. The shrinking portion can suppress deformation of the end in the first direction.

[0016] In a preferred embodiment, the invention according to embodiment 8 may have the following features in the invention according to any of embodiments 1 to 7. The continuous packaging body has a first direction in which the packaging bodies are adjacent to each other, and a second direction perpendicular to the first direction. The pet diaper is housed in the packaging body in a folded state, folded with the fold as the starting point. Of the regions obtained by dividing the pet diaper into three equal parts in the first direction in the folded state, the maximum thickness of the first side region located on the side in the first direction is thicker than the maximum thickness of the first central region located in the center of the three divided regions in the first direction. The end of the pet diaper in the first direction is likely to be located near the packaging joint and is a part that is easily gripped or twisted and subjected to force when separating the packaging joint in an attempt to cut the packaging body. However, the thicker maximum thickness of the first side region can suppress deformation of the end of the pet diaper in the first direction.

[0017] According to a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to any one of embodiments 1 to 8. The pet diaper is folded based on a crease and accommodated in the package in the folded state. Among the regions obtained by trisecting the pet diaper in the second direction in the folded state, the maximum thickness of the second side region located on the side in the second direction is larger than the maximum thickness of the second central region located at the center in the second direction among the trisected regions. The end portion of the pet diaper in the second direction is not provided with a package joining portion adjacent to the accommodation space, and is easily deformed when a force is applied from the outside of the package. However, since the maximum thickness of the second side region is large, deformation of the end portion of the pet diaper in the second direction can be suppressed.

[0018] According to a preferred embodiment, the invention according to embodiment 10 may have the following features in the invention according to any one of embodiments 1 to 9. The pet diaper is folded based on a crease and accommodated in the package in the folded state. The pet diaper is formed with a cutting line that forms a tail hole for inserting the tail of the pet. The cutting line is in the shape of an arc extending convexly from base portions located at both ends. The cutting line is spaced apart from an outer edge of the pet diaper in the folded state. If the cutting line reaches the outer edge of the diaper, the portion surrounded by the cutting line will lift up, and the lifted portion protrudes outside the diaper and is easily deformed. Since the cutting line is spaced apart from the outer edge of the diaper, unintended lifting of the region surrounded by the cutting line can be suppressed.

[0019] According to a preferred aspect, the invention according to aspect 11 may have the following features in the invention according to any one of aspect 10. The arc shape of the cutting line protrudes in the first direction. In the folded state, the outer edge of the pet diaper in the first direction includes a first outer edge located on the vertex side of the convex portion, and a second outer edge located on the base point side. The distance between the base point portion and the second outer edge is longer than the distance between the vertex of the convex portion and the base point portion in the first direction. Since the distance between the second outer edge located on the base point side and the base point portion in the first direction is longer than the distance G2 between the base point portion and the vertex in the first direction, when a region surrounded by the cutting line with the base point portion as a base point is turned up, it is possible to suppress the turned-up region from reaching the outer edge of the diaper in the first direction.

[0020] According to a preferred aspect, the invention according to aspect 12 may have the following features in the invention according to any one of aspects 1 to 11. The outer surface of the pet diaper is visible from the outer surface of the continuous package through the packaging sheet. According to this aspect, the diaper as the content can be checked from the outer surface of the package without opening the package. Therefore, for example, when using a diaper selected from a plurality of types of diapers, such as when keeping a plurality of pets, the type of the diaper can be determined without opening the package. In addition, the diaper can be checked from the outside of the package at the time of purchase, and the package can be cut off and purchased without mistaking the diaper.

[0021] According to a preferred aspect, the invention according to aspect 13 may have the following features in the invention according to any one of aspects 1 to 12. Between the adjacent packages, a package joining portion formed by joining the packaging sheets extends along the second direction. On the outer surface of the packaging sheet, a plurality of information display units for displaying information of the pet diaper are provided side by side in the first direction. The pitch of the package joining portions in the first direction is at least twice the pitch of the information display units in the first direction. According to this aspect, regardless of the position where the package is separated, the entire information display unit can be displayed by a plurality of information display units or one information display unit.

[0022] (2) Continuous package according to the first embodiment The continuous packaging body 200 for pet diapers according to the embodiment will be described below with reference to the drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of each dimension may differ from those of reality. Therefore, specific dimensions should be determined by referring to the following explanation. In addition, there may be parts where the relationships and ratios of dimensions differ between drawings.

[0023] Figure 1 is a perspective view of the continuous packaging 200 according to the first embodiment. Figure 2 is a plan view of the packaging 100 according to the first embodiment. Figure 3 is a schematic cross-sectional view along line AA shown in Figure 2. The continuous packaging 200 consists of multiple continuous packaging units 100, each containing a pet diaper (hereinafter referred to as diaper 1) wrapped in a packaging sheet 50. The continuous packaging 200 has a first direction D1 in which the packaging units 100 are adjacent to each other, a second direction D2 perpendicular to the first direction D1, and a third direction along the thickness direction T of the diaper. The number of packaging units 100 in the continuous packaging 200 is not limited and may be two or more. The continuous packaging 200 is displayed in stores as a continuous packaging 200, and is configured so that a predetermined number of packaging units 100 can be separated via a cutting line 210 to provide a predetermined number of packaging units 100.

[0024] The packaging sheet 50 is a continuous sheet in the first direction D1. The packaging sheet 50 is folded inward in the second direction D2, starting from a pair of folds extending along the first direction D1, so as to surround the diaper 1, and the ends of the packaging sheet 50 in the second direction D2 are joined at the central joint 51 to form a cylindrical shape. The cylindrically formed packaging sheet 50 is joined at the packaging joint 52 by heat welding or the like. The packaging joint 52 is provided between adjacent packaging bodies 100. The packaging joint 52 is provided along the second direction D2 and separates adjacent packaging bodies 100. The cutting line 210 is provided at the packaging joint 52. The packaging sheet 50 can be made of a well-known resin sheet, and may be made of thermoplastic resin such as polyethylene, polypropylene, or PET.

[0025] An information display section 55 for displaying information about pet diapers may be provided on the outer surface of the packaging sheet 50. The information display section 55 displays information related to the diaper 1. The information related to the diaper 1 may include not only name information such as the product name and brand name, but also information indicating the product's functions and manufacturing information (manufacturer, serial number, etc.). Multiple information display sections 55 may be provided side by side in the first direction D1. The information display sections 55 side by side in the first direction D1 may be spaced apart in the first direction D1, or they may be adjacent to each other in the first direction D1. In this embodiment, the information display sections 55 are spaced apart in the first direction D1.

[0026] Diaper 1 is a diaper for pets. "Pet" broadly includes vertebrates and invertebrates, and typically includes companion animals such as cats, dogs, rabbits, and hamsters. In this embodiment, diaper 1 is a dog diaper, preferably a male dog diaper. In a modified example, it may be a cat diaper. Diaper 1 may be housed in the packaging 100 in the unfolded state shown in Figure 4, or in the folded state shown in Figure 5(C). In this embodiment, diaper 1 is housed in the packaging 100 in a folded state, folded along the creases. The folded state of diaper 1 will be described later.

[0027] Figure 4 is a plan view of the unfolded diaper 1 as seen from the back side, and Figure 5 is a diagram showing the folded state of the diaper. For the sake of explanation, Figures 4 and 5 show the diaper 1 in an unfolded and extended state in the planar direction. The extended state is the state in which the diaper 1 is extended in the planar direction to the extent that wrinkles caused by elastic members such as the waist contraction portion 26 are no longer visible. The diaper 1 has a waist direction W that is aligned with the waist direction of the pet, an intersecting direction Z that is perpendicular to the waist direction W, and a thickness direction T that is perpendicular to the waist direction W and the intersecting direction Z. The thickness direction T of the diaper is aligned with the third direction D3 of the continuous packaging 200.

[0028] The crossing direction Z of diaper 1 extends in the longitudinal direction of the pet, that is, from the crotch side to the side away from the crotch. The thickness direction T extends from the surface side that is in contact with the pet when worn, and from the back side that is facing outwards when worn. Diaper 1 is not positioned to cover the pet from the belly side through the crotch to the back side, but is worn by wrapping it around the waist. Therefore, the length of diaper 1 in the waist direction W is longer than the length of diaper 1 in the crossing direction Z.

[0029] Diaper 1 comprises at least a surface sheet 10 (see Figure 5(A)), a back sheet 20, and an absorbent core 30. The surface sheet 10 is positioned on the side that comes into contact with the pet and is located on the outer surface of diaper 1. The surface sheet 10 is permeable to liquids, allowing bodily fluids to pass through to the absorbent core 30. The absorbent core 30 is positioned between the surface sheet 10 and the back sheet 20. The absorbent core 30 is made up of laminated absorbent materials such as pulp. A core wrap sheet (not shown) may be provided to cover the absorbent core 30. The absorbent core 30 is positioned in the center of diaper 1 in the waist direction W and does not need to be located on the outer side of diaper 1 in the waist direction W. Also, the absorbent core 30 is positioned in the center of diaper 1 in the intersecting direction Z and does not need to be located on the outer side of diaper 1 in the intersecting direction Z.

[0030] The backing sheet 20 may have a liquid-impermeable backing film 21 and a backing nonwoven fabric 22 located on the back side of the backing film 21. The backing nonwoven fabric 22 is placed on the outer surface of the pet diaper. A printed area 24 may be provided on either the backing film 21 or the backing nonwoven fabric 22. In this embodiment, the printed area 24 is provided on the backing film 21 and is configured to be visible from the outer surface of the diaper 1 through the backing nonwoven fabric 22.

[0031] At both ends of the diaper in the intersecting direction Z, waist contraction sections 26 that expand and contract in the waist direction W may be provided. The waist contraction sections 26 are located outside the intersecting direction Z of the absorbent core 30 and may be composed of a surface sheet 10, a back sheet 20, and a waist elastic member 25. The waist elastic member 25 may be positioned between the surface sheet 10 and the back sheet 20 and fixed to the surface sheet 10 and the back sheet 20 in an extended state in the waist direction W.

[0032] The diaper 1 may have a hook sheet 40 on which multiple hook members are provided to connect the outer surfaces of the pet diaper that are facing each other when the diaper is worn on a pet. The outer surface of the diaper 1 includes a back surface which is the surface facing the back sheet 20 and a front surface which is the surface facing the front sheet 10. The hook members are mechanical fasteners that engage with a sheet member such as the front sheet. In this embodiment, the hook sheet 40 is provided on the back surface of the diaper 1 and has multiple mechanical fasteners that engage with the front sheet 10. The engagement of the mechanical fasteners with the front sheet 10 maintains the wearing state of the pet diaper. In a modified example, the hook sheet 40 may be provided on the front surface and configured to be able to engage with the back nonwoven fabric 22.

[0033] Figure 5 is a diagram illustrating an example of how diaper 1 is folded. Figure 5(A) shows the unfolded state, that is, the state in which it is not folded by any folds, and is a view from the front side of diaper 1. From the state shown in Figure 5(A), diaper 1 is folded in the waist direction W, starting from the first fold FL1 located in the center of the waist direction W of diaper 1. Figure 5(B) shows the state after being folded starting from the first fold FL1. Next, in the state after being folded starting from the first fold FL1, diaper 1 is folded in the waist direction W, starting from the second fold FL2 located in the center of the waist direction W of diaper 1. Figure 5(C) shows the state after being folded starting from the second fold FL2. In this folded state, folded twice in the waist direction, diaper 1 is housed in the packaging 100. In the folded state, the length W of the diaper 1 in the waist direction may be shorter than the length Z of the diaper 1 in the cross direction.

[0034] As shown in Figure 2, in the first embodiment, the continuous packaging 200 has the diaper 1's crossing direction Z aligned with the first direction D1 of the continuous packaging, and the diaper 1's waist direction W aligned with the second direction D2 of the continuous packaging. The length of the packaging 100's storage space in the crossing direction Z relative to the length of one diaper 1 in the crossing direction Z may be 1.1 to 1.3 times. Also, the difference between the length of the packaging 100's storage space in the crossing direction Z and the length of one diaper in the crossing direction Z may be 20 mm to 30 mm. In a modified example, the diaper 1's crossing direction Z may be aligned with the second direction D2 of the continuous packaging 200, and the diaper's waist direction W may be aligned with the first direction D1 of the continuous packaging 200.

[0035] The continuous packaging 200 of this embodiment is configured to house multiple diapers in a single packaging 100 and maintain the quality of the housed diapers 1. Next, the configuration for maintaining the quality of the diapers 1 will be described in detail. Note that if the diapers 1 in the packaging have shrinkable parts such as waist shrinkage parts, they are housed in a shrunk state. Therefore, in the following description, unless otherwise specified, the description refers to the diaper in its natural state. For example, a folded diaper is a diaper in both a folded state and its natural state. The natural state is defined as the state after opening the packaging 100 and placing it on a flat surface for 5 minutes.

[0036] The outer surfaces of adjacent diapers 1 are in contact with each other in the thickness direction T. The outer surfaces of the diapers 1 have fine irregularities formed by the surface irregularities of the absorbent core 30, etc. By having the outer surfaces of adjacent diapers 1 in the thickness direction T in contact with each other, displacement of the diapers 1 can be suppressed. This suppresses the displacement of individual diapers 1 within the packaging 100, and prevents the outer edges of the displaced diapers 1 from hitting the inner wall of the packaging and deforming, as well as preventing the outer edges of the displaced diapers 1 from deforming due to external forces on the packaging. In a packaging containing multiple diapers 1, deformation of the diapers 1 can be suppressed and the quality of the diapers 1 can be maintained. In this embodiment, the back surfaces of adjacent diapers 1 are in contact with each other, but the back surface of one diaper 1 may be in contact with the front surface of the other diaper 1, or the front surfaces of the diapers may be in contact with each other.

[0037] Furthermore, since diapers 1 are not individually wrapped by a packaging sheet, it is possible to select a diaper 1 by visually inspecting its outer surface when using it. Therefore, if the outer designs of the diapers 1 are different, it is easier to select the desired diaper 1. In addition, since diapers 1 are not individually wrapped by an individual packaging sheet, when packaging diapers 1 with the packaging sheet 50, it is possible to check the condition of the diaper 1 while packaging, or to combine and package diapers 1 with different designs (for example, composed of printed sections 24).

[0038] Each individual package 100 contains two or more diapers 1, so a user can carry multiple diapers 100 by carrying one package 100. In this embodiment, two diapers are contained in one package 100, but the configuration is not limited to this, and three or more diapers may be contained in one package 100.

[0039] The hook sheet 40 of the diaper 1 may extend along the first direction D1 of the continuous packaging body 200. In this embodiment, the intersecting direction Z is along the first direction D1, and the length of the hook sheet 40 in the first direction D1 may be longer than the length of the hook sheet 40 in the second direction D2. The packaging joint 52 of the continuous packaging body 200 is formed over the entire area of ​​the continuous packaging body 200 in the second direction D2. The packaging joint 52 is where the packaging sheets 50 are joined together, and its rigidity is higher than that of the surrounding area. According to this embodiment, the rigidity of the continuous packaging body 200 in the second direction D2 can be increased by the packaging joint 52 extending along the second direction D2, and the rigidity of the continuous packaging body 200 in the first direction D1 can be increased by the hook sheet 40 extending along the first direction D1. Therefore, the rigidity of both the first direction D1 and the second direction D2 of the continuous packaging body 200 can be increased, and deformation of the diaper 1 contained inside can be suppressed.

[0040] The length of the hook sheet in the first direction D1 is 80% or more of the length of the diaper 1 in the first direction D1 when folded. According to this embodiment, the rigidity can be increased by the hook sheet 40 in a range of 80% or more of the length of the diaper 1 in the first direction D1 when folded, and deformation of the diaper 1 in the first direction D1 when folded can be effectively suppressed. The hook sheet 40 does not need to be folded by creases FL1 and FL2 when folded. This makes it easier to maintain the rigidity of the hook sheet 40 without creases.

[0041] The hook sheet 40 may be exposed to the outside of the diaper 1 when folded. The hook members of the hook sheet 40 may engage with the outer surface of adjacent diapers 1 in the thickness direction T. By engaging the hook members with adjacent diapers, the relative positions of adjacent diapers within the packaging are less likely to shift. Therefore, friction between the outer surfaces of the diapers is suppressed, and fraying of the sheet on the outer surface of the diaper can be suppressed. The hook sheet 40 may be exposed to the outer surface of the diaper 1 by the contraction of contraction parts such as the waist contraction part, or by the folds that fold the diaper 1 being inclined with respect to the intersecting direction Z.

[0042] In the folded state, a contracted portion may be formed outside the outer edge of the absorption core 30 by the elastic member. According to this embodiment, the contracted portion can alleviate the force acting on the outer edge of the absorption core 30, thereby suppressing deformation of the absorption core 30. In the folded state, the body contracted portion 26 is positioned outside the outer edge of the absorption core 30 in the first direction D1, and constitutes the contracted portion of this embodiment.

[0043] The shrinkable portion may be provided along the second direction D2 at the end of the folded diaper 1 in the first direction D1. The end of the diaper 1 in the first direction D1 is likely to be located near the packaging joint 52 and is a part that is easily subjected to force by being grasped or twisted when separating the packaging joint 52. The shrinkable portion can suppress deformation of the end in the first direction D1. The shrinkable portion may be provided over the entire area of ​​the second direction D2 at the end of the folded diaper 1 in the first direction D1. This can suppress deformation over the entire area of ​​the end of the diaper 1 in the first direction D1.

[0044] In the folded state, the maximum thickness of the first side region RS1, located on the side in the first direction D1, of the three equal regions obtained by dividing the diaper 1 in the first direction D1, may be thicker than the maximum thickness of the first central region RC1, located in the center of the first direction D1. This thickness is the thickness of a single diaper, not the thickness of multiple diapers stacked together. The end of the diaper 1 in the first direction D1 is likely to be located near the packaging joint 52 and is a part that is easily subjected to force by being grasped or twisted when separating the packaging joint in an attempt to detach the packaging 100. However, the greater maximum thickness of the first side region can suppress deformation of the end of the diaper 1 in the first direction D1.

[0045] The outer surface of diaper 1 may be visible from the outer surface of the continuous packaging 200 through the packaging sheet 50. According to this embodiment, the contents, which are diapers, can be confirmed from the outer surface of the packaging 100 without opening the packaging 100. Therefore, for example, when using diapers selected from several types, such as when owning multiple pets, the type of diaper can be identified without opening the package. Also, the diaper can be confirmed from the outside of the packaging at the time of purchase, and the packaging can be cut off and purchased without mistakenly selecting the wrong diaper. Note that "visible" means that the object can be seen by a subject with good visual acuity (1.0 or better) in both eyes at a distance of approximately 30 to 50 cm in a brightly lit room (approximate color temperature: 4600 to 5400 K (Kelvin)) (approximate: 500 to 750 lx (lux)).

[0046] Furthermore, the printed area 24 on the outer surface of the diaper 1 may be visible from the outer surface of the continuous packaging 200 through the packaging sheet 50. Being able to see the printed area 24 makes it easier to accurately identify the type of diaper 1 from the outer surface of the packaging 100. Also, if the information display area 55 on the packaging sheet 50 and the printed area 24 on the diaper 1 have the same design (a star mark in this embodiment), a sense of design uniformity can be achieved through this mark. Furthermore, even if an external force is applied to the packaging 100 and the packaging sheet 50 deforms, the printed area of ​​the diaper 1 can still be seen. In addition, having both the information display area 55 on the packaging sheet 50 and the printed area 24 on the diaper 1, and both being visible from the outer surface of the packaging 100, increases the number of designs, making it easier to notice the product when it is on display.

[0047] The pitch of the packaging joint 52 in the first direction D1 may be twice or more the pitch of the information display section 55 in the first direction D1. According to this embodiment, no matter where the package body 100 is separated, the entire information display section 55 can be shown by multiple information display sections 55 or by a single information display section 55. Furthermore, the pitch of the packaging joint 52 in the first direction D1 may be four times or less the pitch of the information display section 55 in the first direction D1. This makes it easier to secure the length of the information display section 55 in the first direction D1 arranged within a single package body and to ensure the visibility of the information display section 55.

[0048] Next, a continuous packaging body according to the second embodiment will be described with reference to Figures 6 and 7. In the following description, the same reference numerals will be used for components similar to those in the first embodiment, and their explanation will be omitted. Figure 6 is a rear view of the unfolded diaper 1X according to the second embodiment. The diaper 1X of the second embodiment is a diaper for dogs, preferably for female dogs.

[0049] Diaper 1X is fitted so as to cover the pet from the ventral side, through the crotch, to the dorsal side. The crossing direction Z extends in the longitudinal direction of the pet, that is, in the direction connecting the crotch side to the side away from the crotch. Therefore, the length of diaper 1X in the crossing direction Z is longer than the length of diaper 1 in the waist direction W. In the second embodiment, the continuous packaging body is housed in the packaging body 100 such that the crossing direction Z of diaper 1 is along the first direction D1 of the continuous packaging body, and the waist direction W of diaper 1X is along the second direction D2 of the continuous packaging body. However, in a modified example, diaper 1X may be housed in the packaging body 100 such that the crossing direction Z of diaper 1X is along the second direction D2 of the continuous packaging body, and the waist direction W of diaper 1X is along the first direction D1 of the continuous packaging body.

[0050] In the second embodiment, the hook sheet 40X is provided on a fastening tape 45 that extends outward on both sides in the waist direction W at one end of the diaper 1X in the intersecting direction Z. The hook sheet 40X is positioned on the surface side of the fastening tape 45. The hook sheet 40X may be a mechanical fastener and may be configured to be able to lock onto a back nonwoven fabric 22 or a target portion (not shown) provided on the back surface of the diaper.

[0051] Diaper 1X may be provided with a cutting line 70 that forms a tail hole into which a pet's tail can be inserted. The tail hole is a through-hole into which a pet's tail can be inserted, and the cutting line 70 is a cut or perforation for forming the tail hole. The cutting line 70 may be formed on the surface sheet 10 and the back sheet 20 in areas that do not overlap with the absorbent core 30. In a plan view, the cutting line 70 may be in the shape of an arc extending convexly from base points 71 located at both ends. The base points 71 are spaced apart in the second direction D2, and the arc shape of the cutting line 70 may protrude in the first direction D1. That is, the vertex 72 of the protrusion and the base points 71 may be spaced apart in the first direction.

[0052] Figure 7 illustrates an example of how the diaper 1X can be folded. Figure 7(A) shows the unfolded state, viewed from the surface side of the diaper 1. As shown in Figure 7(A), in the unfolded state, the hook sheet 40X may be folded inward in the waist direction W and secured to the surface sheet 10. That is, only the hook members of the hook sheet 40X may be folded so that the hook members are not exposed.

[0053] From the state shown in Figure 7(A), the diaper 1X is folded inward in the waist direction W, starting from the third fold FL3 located on the side of the waist direction W. The third fold FL3 may be provided on both sides of the outer edge of the absorbent core 30 in the waist direction W. Figure 7(B) shows the state after folding with the third fold FL3 as the starting point. Next, with the diaper 1X folded with the third fold FL3 as the starting point, it is folded in the crossing direction Z, starting from the fourth fold FL4 located in the center of the crossing direction Z of the diaper 1X. Figure 7(C) shows the state after folding with the fourth fold FL4 as the starting point. Next, with the diaper 1X folded with the fourth fold FL4 as the starting point, it is folded in the crossing direction Z, starting from the fifth fold FL5 located in the center of the crossing direction Z of the diaper 1X. Figure 7(D) shows the state after folding with the fifth fold FL5 as the starting point. In this folded state, the diaper 1X may be housed within the packaging 100. In the folded state, the length W of the diaper 1X in the waist direction may be longer than the length Z of the diaper 1 in the cross direction.

[0054] Multiple hook sheets 40X may be arranged with spacing between them in the second direction D2 when folded. In the second embodiment, the hook sheets 40X are arranged with spacing in the waist direction W when folded, and the waist direction W is aligned with the second direction D2. According to this embodiment, the spacing between the hook sheets 40 in the second direction D2 acts as a buffer area, partially absorbing deformation in the second direction D2 and suppressing deformation of the entire diaper 1X in the second direction D2.

[0055] In the folded state, the maximum thickness of the second side region RS2, located on the side of the region obtained by dividing the diaper 1X into three equal parts in the second direction D2, may be thicker than the maximum thickness of the second central region RC2, located in the center of the region obtained by dividing the region into three equal parts in the second direction D2. The end of the diaper 1X in the second direction D2 is not adjacent to the storage space where the packaging joint 52 is located, and is easily deformed when force is applied from the outside of the packaging body 100. However, the deformation of the end of the diaper 1X in the second direction D2 can be suppressed by having a thicker maximum thickness in the second side region RS2.

[0056] The cutting line may be spaced apart from the outer edge of the diaper in the folded state. The outer edge of diaper 1 in the first direction is the fold or edge of the diaper along the second direction, and in this embodiment, the fourth fold FL4 and the fifth fold FL5 constitute the outer edge. That is, the cutting line 70 may be spaced apart from the fourth fold FL4 and the fifth fold FL5. If the cutting line 70 reaches the outer edge of diaper 1X, the portion enclosed by the cutting line 70 will lift up, and the lifted portion will easily deform and protrude to the outside of the diaper. Because the cutting line 70 is spaced apart from the outer edge of the diaper, it is possible to suppress the unintended lifting of the region enclosed by the cutting line 70.

[0057] In the folded state, the outer edge of the diaper 1X in the first direction D1 has a first outer edge located on the side of the apex 72 of the convex part and a second outer edge located on the side of the base point 71. The outer edge of the diaper 1X in the first direction D1 is the outer edge of the diaper that follows the second direction. In this embodiment, the first outer edge located on the side of the apex 72 of the convex part is the fifth fold FL5, and the second outer edge located on the side of the base point 71 is the fourth fold FL4. The distance G1 between the base point 71 and the second outer edge may be longer than the distance G2 between the apex 72 of the convex part and the base point 71 in the first direction D1. According to this embodiment, the distance G1 between the second outer edge (the fourth fold FL4 in this embodiment) located on the base point 71 side and the base point 71 in the first direction D1 is longer than the distance G2 between the base point 71 and the vertex 72 in the first direction D1. Therefore, when the area enclosed by the cutting line with the base point 71 as the base point is turned over, it is possible to prevent the turned-over area from reaching the outer edge of the diaper in the first direction.
