Summary of the Invention

Problems to be Solved by the Invention

[0004] For this type of absorbent sheet, it is desirable that it can be easily taken out and used immediately when the pet urinates. In order to facilitate the removal of the absorbent sheet, it is conceivable to accommodate a plurality of absorbent sheets in a standing posture in the packaging container so that the absorbent sheet can be pinched from the thickness direction and taken out of the packaging container. However, when the absorbent sheet is accommodated in a standing posture, the absorbent sheet may fall down, making it difficult to take out the absorbent sheet from the packaging container.

[0005] Therefore, an object of the present disclosure is to provide a packaging container containing an absorbent sheet that can easily take out the absorbent sheet.

Means for Solving the Problems

[0006] The packaging container containing absorbent sheets on one side includes a packaging container including a bottom plate, a top plate, a front plate, a back plate, a first side plate, and a second side plate, and a plurality of absorbent sheets accommodated in the packaging container. The bottom plate and the top plate face each other in the vertical direction, the front plate and the back plate face each other in the depth direction, the first side plate and the second side plate face each other in the width direction. Each of the plurality of absorbent sheets includes a water-permeable surface sheet, a back sheet on the opposite side of the surface sheet, and an absorber disposed between the surface sheet and the back sheet. It is folded in half along a fold line and accommodated in the packaging container in an upright posture with the fold line directed in the vertical direction. The packaging container has an opening line formed continuously on the front plate, the back plate, the first side plate, and the second side plate and including the top plate to separate the upper part of the container including the top plate from the lower part of the container including the bottom plate to open the packaging container. In the vertical direction, the opening line is located on the bottom plate side rather than the top of the plurality of absorbent sheets in the upright posture, and the distance between the opening line and the top in the vertical direction is smaller than the stiffness and softness of the absorbent sheet folded in half.

[0007] In this packaging container containing absorbent sheets, since the opening line is located on the bottom plate side rather than the top of the plurality of absorbent sheets in the upright posture, when the packaging container is opened along the opening line to separate the upper part of the container from the lower part of the container, the upper parts of the plurality of absorbent sheets are exposed from the packaging container through the opening. The user can insert a finger into the packaging container through the opening and pick out the absorbent sheet from the packaging container by pinching it in the thickness direction. On the other hand, since each of the plurality of absorbent sheets is folded in half along a fold line, it is not easily toppled over in the packaging container. In particular, since the distance between the opening line and the top in the vertical direction is smaller than the stiffness and softness of the absorbent sheet folded in half, it is possible to prevent the absorbent sheet from leaning against the lower part of the container and bending. Therefore, since the upright posture of the absorbent sheet is maintained, the absorbent sheet can be easily taken out according to this packaging container.

[0008] The plurality of absorbent sheets may be arranged side by side in the width direction in a folded-in-half state. In this packaging container, the absorbent sheets arranged side by side in the width direction can be easily taken out.

[0009] The back sheet has an outer surface on the side opposite to the inner surface facing the absorber, and a surface fastener is provided on the outer surface of the back sheet. Each of the plurality of absorbent sheets may be folded in half along a fold line so that the back sheet is disposed inside. By folding the absorbent sheet in half so that the back sheet provided with the surface fastener is disposed inside and accommodating it in the packaging container, the surface fastener is prevented from sticking to the surface sheet of another absorbent sheet. Therefore, the absorbent sheets can be individually taken out from the packaging container.

[0010] The plurality of absorbent sheets include a first row of absorbent sheet groups arranged in the width direction and a second row of absorbent sheet groups arranged adjacent to the first row of absorbent sheet groups in the depth direction and arranged in the width direction. The plurality of absorbent sheets may be arranged in the packaging container such that the fold line of the first row of absorbent sheet groups and the fold line of the second row of absorbent sheet groups face each other. By arranging the plurality of absorbent sheets such that the fold line of the first row of absorbent sheet groups and the fold line of the second row of absorbent sheet groups face each other, one of the surface fasteners of the first row of absorbent sheet groups and the second row of absorbent sheet groups is prevented from sticking to the surface sheet of the other of the first row of absorbent sheet groups and the second row of absorbent sheet groups. Therefore, the absorbent sheets can be individually taken out from the packaging container.

[0011] The back sheet is a resin film having an outer surface on the side opposite to the inner surface facing the absorber, and a surface fastener is provided on the outer surface of the back sheet. Each of the plurality of absorbent sheets may be folded in half along a fold line so that the surface sheet is disposed inside. It is difficult to attach the surface fastener to the resin film. Therefore, by configuring the back sheet with a resin film, even when the absorbent sheet is folded in half along a fold line so that the surface sheet is disposed inside, the surface fastener is prevented from sticking to the back sheet of another absorbent sheet. Therefore, the absorbent sheets can be individually taken out from the packaging container.

[0012] The distance between the opening line and the top in the vertical direction may be greater than the stiffness of the absorbent sheet when it is not folded. In this case, when the packaging container is opened along the opening line, the exposed portion of the absorbent sheet can be increased, so that the absorbent sheet can be easily taken out from the packaging container.

[0013] The opening line may be formed on the bottom plate side rather than on the center line of the packaging container in the vertical direction. In this case, when the packaging container is opened along the opening line, the exposed portion of the absorbent sheet can be increased, so that the absorbent sheet can be easily taken out from the packaging container.

[0014] The opening line is formed on the top plate side rather than on the center line of the plurality of absorbent sheets in the vertical direction. In this case, it becomes easier for the absorbent sheet to maintain an upright posture, so that the absorbent sheet is prevented from sagging and bending at the lower part of the container.

[0015] The distance between the opening line and the top in the vertical direction may be 50.2 mm or more and 95.2 mm or less. In this case, when the packaging container is opened along the opening line, it is possible to increase the exposed portion of the absorbent sheet while preventing the absorbent sheet from sagging and bending at the lower part of the container.

[0016] The opening line includes a front opening line formed on the front plate, a rear opening line formed on the rear plate, a first side opening line formed on the first side plate, and a second side opening line formed on the second side plate. The first side opening line may include a first portion connected to the front opening line, a second portion connected to the rear opening line, and a third portion disposed between the first portion and the second portion and formed at a position shifted in the vertical direction with respect to the first portion and the second portion. In this case, the opening line can be easily broken starting from the third portion of the first side opening line.

[0017] The second side opening line is located closer to the top panel side than the first part and the second part of the first side opening line in the vertical direction. The front opening line and the back opening line may extend in a direction inclined with respect to the width direction so as to approach the top panel as they approach the second side opening line. As described above, when the front opening line and the back opening line are inclined, when the packaging container is opened along the opening line, the height of the lower part of the container in the vertical direction increases as it approaches the second side panel. As a result, when the number of absorbent sheets accommodated in the packaging container is large, the absorbent sheets can be easily taken out. On the other hand, when the number of absorbent sheets decreases, the absorbent sheets are supported by the second side panel and are less likely to fall, so the standing posture of the absorbent sheets is maintained.

[0018] In the vertical direction, the opening lines may be arranged at the same height position at the boundary between the front panel and the first side panel, the boundary between the front panel and the second side panel, the boundary between the back panel and the first side panel, and the boundary between the back panel and the second side panel. In this case, the absorbent sheets can be taken out from any direction.

[0019] The packaging container is provided with a stopper piece formed on at least one of the front panel and the back panel and foldable into the packaging container along a folding line. The stopper piece may be located closer to the bottom panel side than the opening line in the vertical direction. In this case, by folding the stopper piece into the packaging container, the absorbent sheets in the packaging container are supported by the stopper piece, and the absorbent sheets are prevented from falling in the packaging container.

[0020] Each of the plurality of absorbent sheets includes an absorption part in which an absorber is disposed between a front surface sheet and a back surface sheet, and a flap part formed so as to surround the absorption part and in which no absorber is disposed. The stopper piece may contact the absorption part when folded into the packaging container along the folding line. Since the absorption part has higher rigidity than the flap part, the absorbent sheet can be reliably supported by the stopper piece contacting the absorption part. Therefore, the absorbent sheets are prevented from falling in the packaging container.

[0021] The upper edge portion of the stopper piece may be located on the opening line side with respect to the intermediate line between the opening line and the bottom plate in the vertical direction. In this case, it is possible to more reliably prevent the absorbent sheet from falling down inside the packaging container.

[0022] The packaging container may be a paper carton. Note that the opening line may include perforations. In this case, the packaging container can be easily opened.

[0023] The opening line may include a pair of upper and lower perforations and a zipper portion formed between the pair of upper and lower perforations. In this case, the packaging container can be easily opened.

[0024] The packaging container containing the absorbent sheet according to another aspect includes a packaging container including a bottom plate, a top plate, a front plate, a back plate, a first side plate, and a second side plate, and a plurality of absorbent sheets accommodated in the packaging container. The bottom plate and the top plate face each other in the vertical direction, the front plate and the back plate face each other in the depth direction, the first side plate and the second side plate face each other in the width direction. Each of the plurality of absorbent sheets includes a water-permeable surface sheet, a back sheet on the opposite side of the surface sheet, an absorber disposed between the surface sheet and the back sheet, and a release sheet covering the outer surface of the back sheet. The absorbent sheets are accommodated in the packaging container in an upright posture with their thickness direction oriented in the width direction. The packaging container has an opening line formed continuously on the front plate, the back plate, the first side plate, and the second side plate for separating the upper part of the container including the top plate from the lower part of the container including the bottom plate to open the packaging container. In the vertical direction, the opening line is formed at a position closer to the bottom plate side than the top of the plurality of absorbent sheets in the upright posture, and the distance between the opening line and the top in the vertical direction is smaller than the stiffness-flexibility of the absorbent sheet.

[0025] As described above, in this packaging container, since the upright posture of the absorbent sheet is maintained when the packaging container is opened, the absorbent sheet can be easily taken out.

[0026] The distance between the opening line and the top in the vertical direction may be greater than the stiffness and softness of the absorbent sheet from which the release sheet has been peeled off. In this case, when the packaging container is opened along the opening line, the exposed portion of the absorbent sheet can be enlarged, so that the absorbent sheet can be easily pinched from the thickness direction and can be easily taken out from the packaging container.

Mode for Carrying Out the Invention

[0029] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are given to the same elements, and duplicate descriptions are omitted. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

[0030] FIG. 1 is a perspective view showing a packaging container 1 containing an absorbent sheet according to an embodiment. The packaging container 1 houses a PET sheet 2 shown in FIG. 2. The PET sheet 2 is an example of an absorbent sheet having water absorbency. The packaging container 1 defines an internal space for housing a plurality of PET sheets 2.

[0031] First, a usage example of the PET sheet 2 will be described with reference to FIGS. 3 and 4. FIG. 3 shows an excrement treatment sheet (hereinafter referred to as "treatment sheet") 100 for pets. The treatment sheet 100 is placed in a pet breeding space (for example, indoors) and is used to keep the breeding space clean. That is, the treatment sheet 100 provides an excretion space for the pet. The treatment sheet 100 may be placed directly on the floor or ground of the breeding space, or may be placed on a tray.

[0032] The treatment sheet 100 has a rectangular planar shape and includes a liquid-permeable surface sheet, a liquid-impermeable back sheet, and an absorber disposed between the surface sheet and the back sheet. The pet gets on the treatment sheet 100 and excretes. The treatment sheet 100 absorbs the excrement U of the pet.

[0033] In this specification, "pet" broadly includes vertebrates and invertebrates, and typically includes pets such as dogs, cats, rabbits, hamsters, etc. Pets include animals other than mammals such as birds, reptiles, and amphibians. As the excrement U of a pet, typically urine is mentioned, but it includes body fluids that can be absorbed by absorbents such as low-viscosity feces, saliva, and blood. In the following description, an example of absorbing urine as the excrement U will be described.

[0034] Pets tend to excrete while avoiding the excretion marks (urine marks) on the treatment sheet 100. For this reason, as a result of the pet trying to avoid the urine marks and urinating in an awkward position, it may urinate outside the treatment sheet 100 and dirty the breeding space. To avoid such problems, the user of the treatment sheet 100 (for example, the pet owner) may replace the treatment sheet 100 with a new treatment sheet 100 even though there is an available area (an area where new urine can be absorbed). However, replacing the usable treatment sheet 100 is not appropriate from the perspective of economy and environmental protection.

[0035] To solve the above problems, as shown in FIG. 4, the pet sheet 2 is used by being overlapped on the area (for example, urine marks) where the excrement U of the treatment sheet 100 has been absorbed. By arranging the treatment sheet 100 so as to overlap the urine marks, the urine marks can be visually hidden, so that it is possible to prevent the pet from avoiding the urine marks and urinating outside the treatment sheet 100. As a result, the treatment sheet 100 can be repeatedly used for a long period of time, and improvements can be made from the perspectives of economy and environmental protection.

[0036] Next, the pet sheet 2 housed in the packaging container 1 will be described. FIG. 2 is a perspective view of an exemplary pet sheet 2. FIG. 5 is a plan view of the pet sheet 2 as viewed from the back sheet 42 side described later. FIG. 6 is a schematic cross-sectional view of the pet sheet 2 along the line A-A in FIG. 5.

[0037] As shown in FIG. 2, the pet sheet 2 includes a main body portion 10 having a rectangular planar shape. Note that the planar shape of the main body portion 10 is not limited to a rectangle, and any shape such as a polygon, a circle, or an ellipse can be adopted. The size of the main body portion 10 is determined according to the size or type of the pet using the pet sheet 2. Typically, the area of the pet sheet 2 in plan view is smaller than the area of the processing sheet 100.

[0038] The main body portion 10 has a surface sheet 41 having water permeability, a back sheet 42 on the opposite side of the surface sheet, and an absorber 43 disposed between the surface sheet 41 and the back sheet 42. The surface sheet 41 has a surface 41a that faces the pet side (upward) during use. Typically, the surface sheet 41 is made of a water-permeable nonwoven fabric and moves urine excreted from the pet toward the absorber 43 side. Examples of the nonwoven fabric constituting the surface sheet 41 include an air-through nonwoven fabric, a spunbond nonwoven fabric, or a point-bond nonwoven fabric.

[0039] The back sheet 42 is disposed on the opposite side of the surface sheet 41 in the Z direction and has water impermeability. The back sheet 42 has substantially the same dimensions as the surface sheet 41 and is disposed so as to completely overlap the surface sheet 41 when viewed from the Z direction. The back sheet 42 has an outer surface 42a that is placed on the processing sheet 100 during use. Typically, the back sheet 42 is made of a resin film having water impermeability. As the resin film constituting the back sheet 42, for example, a polyethylene film or a polypropylene film is used. Note that the back sheet 42 may be made of a water-repellent or hydrophobic nonwoven fabric, or may be a laminate in which a resin film and a nonwoven fabric are bonded together.

[0040] The back sheet 42 prevents urine excreted on the pet sheet 2 from moving toward the processing sheet 100 side. Note that the back sheet 42 may have water permeability. This is because since the processing sheet 100 has a function of absorbing urine, there is no major problem even if urine excreted on the pet sheet 2 moves toward the processing sheet 100 side.

[0041] The absorber 43 is disposed between the surface sheet 41 and the back sheet 42 and absorbs the urine of the pet. The absorber 43 has a substantially rectangular planar shape. As shown in FIG. 3, the absorber 43 has dimensions slightly smaller than those of the surface sheet 41 and the back sheet 42 and is disposed at the center of the main body 10. As a result, in the main body 10, an absorption portion 10a in which the absorber 43 is disposed between the surface sheet 41 and the back sheet 42 and a flap portion 10b in which the absorber 43 is not disposed between the surface sheet 41 and the back sheet 42 are formed. Typically, the flap portion 10b is a rectangular frame-shaped region where the surface sheet 41 and the back sheet 42 are bonded together without passing through the absorber 43 and is formed so as to surround the absorption portion 10a. That is, the flap portion 10b is formed along the outer edge of the pet sheet 2.

[0042] The rigidity of the flap portion 10b is lower than that of the absorption portion 10a by the amount that the absorber 43 is absent. That is, the flap portion 10b is thin and soft, so it is easy to pick up by hand. The double-folded pet sheet 2 can be naturally spread by picking up and lifting the flap portion 10b.

[0043] As shown in FIG. 6, the absorber 43 includes an absorbent core 44 and a core wrap 45. The absorbent core 44 contains pulp and a superabsorbent polymer (SAP) and has water absorption. As the pulp of the absorbent core 44, for example, chemical pulp, cellulose fibers such as cellulose fibers, rayon, and acetate are used. As the SAP, for example, starch-based, acrylic acid-based, or amino acid-based particulate or fibrous polymers are used. The core wrap 45 covers the surface of the absorbent core 44.

[0044] As shown in FIGS. 5 and 6, a hook-and-loop fastener 48 having a bonding surface 48a that can be bonded to the treatment sheet 100 is provided on the outer surface 42a of the back sheet 42. The bonding surface 48a of the hook-and-loop fastener 48 engages with the surface of the treatment sheet 100. In the embodiment shown in FIG. 5, four rectangular hook-and-loop fasteners 48 are provided at the corners (four corners) of the outer surface 42a. These four hook-and-loop fasteners 48 are arranged such that the outer edge portions of each hook-and-loop fastener 48 are spaced apart from the outer edge of the back sheet 42. The hook-and-loop fastener 48 is provided with the bonding surface 48a exposed to the outside.

[0045] A plurality of hooks protruding from the hook sheet are formed on the bonding surface 48a. When the pet sheet 2 is placed on the treatment sheet 100, the pet sheet 2 is bonded to the treatment sheet 100 by the plurality of hooks on the bonding surface 48a entangling with the non-woven fabric constituting the surface sheet of the treatment sheet 100. On the other hand, the shapes of the plurality of hooks are designed so that the bonding surfaces 48a of the hook-and-loop fasteners 48 are not bonded to each other.

[0046] The pet sheet 2 is housed in the packaging container 1 in a state of being folded in half along the fold line L1. As shown in FIG. 5, the fold line L1 is a fold line for folding the pet sheet 2 in half, and extends linearly across the absorber 43 along the center line of the main body portion 10. By this fold line L1, the main body portion 10 of the pet sheet 2 is partitioned into a first portion 18A located on one side with respect to the fold line L1 and a second portion 18B located on the other side with respect to the fold line L1.

[0047] As shown in FIG. 5, the hook-and-loop fasteners 48 are arranged at positions shifted from the broken line L1 (positions that do not overlap the broken line L1). More specifically, the four hook-and-loop fasteners 48 are provided at positions that are line-symmetric with respect to the broken line L1. FIG. 7 shows the pet sheet 2 folded in half so that the back sheet 42 is arranged inside along the broken line L1. As described above, since the four hook-and-loop fasteners 48 are provided at positions that are line-symmetric with respect to the broken line L1, when the pet sheet 2 is folded in half along the broken line L1, the two hook-and-loop fasteners 48 provided on the first portion 18A come into contact with the two hook-and-loop fasteners 48 provided on the second portion 18B. As described above, since the hook-and-loop fasteners 48 are designed so that the bonding surfaces 48a do not bond to each other, the first portion 18A and the second portion 18B are not bonded to each other in the folded state and are naturally separated from each other.

[0048] As described above, the pet sheet 2 is housed in the packaging container 1 in a folded state. It is desirable that the pet sheet 2 can be easily taken out and used immediately when the pet urinates. The packaging container 1 houses the pet sheet 2 so that the pet sheet 2 can be easily taken out.

[0049] FIG. 1 is a schematic perspective view showing a packaging container 1 that houses a plurality of pet sheets 2. The packaging container 1 is, for example, a paper carton having a substantially rectangular parallelepiped shape and is made of cardboard or cardboard. As shown in FIG. 1, the packaging container 1 includes a bottom plate 11, a top plate 12, a front plate 13, a back plate 14, a left plate (first side plate) 15, and a right plate (second side plate) 16. In FIG. 1, a width direction X, a depth direction Y, and a vertical direction Z that are orthogonal to each other are shown. The width direction X is a direction that intersects or is orthogonal to the left plate 15 and the right plate 16 of the packaging container 1, and the depth direction Y is a direction that intersects or is orthogonal to the front plate 13 and the back plate 14 of the packaging container 1. The vertical direction Z is a direction perpendicular to the width direction X and the depth direction Y and intersects or is orthogonal to the bottom plate 11 and the top plate 12. In the following description, the direction from the bottom plate 11 to the top plate 12 is referred to as "upward", and the direction from the top plate 12 to the bottom plate 11 is referred to as "downward".

[0050] The front panel 13 and the back panel 14 of the packaging container 1 face each other in the depth direction Y, and the left panel 15 and the right panel 16 face each other in the width direction X. The bottom panel 11 and the top panel 12 of the packaging container 1 face each other in the vertical direction Z of the packaging container 1. The bottom panel 11 is connected to the lower ends of the front panel 13, the back panel 14, the left panel 15, and the right panel 16, closing the bottom of the packaging container 1. The top panel 12 is connected to the upper ends of the front panel 13, the back panel 14, the left panel 15, and the right panel 16, closing the upper part of the packaging container 1. The top panel 12 may be pivotable about the boundary between the top panel 12 and the back panel 14 to open and close the upper part of the packaging container 1. Typically, the packaging container 1 is produced by folding and gluing a single blank sheet.

[0051] As shown in FIG. 1, an opening line 20 is formed in the packaging container 1. The opening line 20 is continuously formed on the front panel 13, the back panel 14, the left panel 15, and the right panel 16. Typically, the opening line 20 is a perforation including a cut portion and a non-cut portion. When the opening line 20 is broken throughout, the packaging container 1 is opened.

[0052] As shown in FIG. 1, the opening line 20 includes a front opening line 23, a back opening line 24, a left opening line (first side opening line) 25, and a right opening line (second side opening line) 26. In one embodiment, the front opening line 23, the back opening line 24, the left opening line 25, and the right opening line 26 extend substantially parallel to the bottom panel 11.

[0053] The front opening line 23 is formed on the front panel 13 and extends in the width direction X. More specifically, the front opening line 23 linearly extends in the width direction X so as to cross the front panel 13 between the boundary portion 31 between the front panel 13 and the left panel 15 and the boundary portion 32 between the front panel 13 and the right panel 16. The rear opening line 24 is formed on the rear panel 14 and extends in the width direction X. The rear opening line 24 linearly extends in the width direction X so as to cross the rear panel 14 between the boundary portion 33 between the rear panel 14 and the left panel 15 and the boundary portion 34 between the rear panel 14 and the right panel 16. The boundary portions 31, 32, 33, and 34 constitute the corners of the packaging container 1.

[0054] The left opening line 25 is formed on the left panel 15 and extends in the depth direction Y. The left opening line 25 linearly extends in the depth direction Y so as to cross the left panel 15 between the boundary portion 31 and the boundary portion 33. One end of the left opening line 25 is connected to one end of the front opening line 23 on the boundary portion 31, and the other end of the left opening line 25 is connected to one end of the rear opening line 24 on the boundary portion 33. The right opening line 26 is formed on the right panel 16 and extends in the depth direction Y. The right opening line 26 linearly extends in the depth direction Y so as to cross the right panel 16 between the boundary portion 32 and the boundary portion 34. One end of the right opening line 26 is connected to the other end of the front opening line 23 on the boundary portion 32, and the other end of the right opening line 26 is connected to the other end of the rear opening line 24 on the boundary portion 34. That is, the opening line 20 continuously extends over the entire circumference of the side surface of the packaging container 1.

[0055] FIG. 8 is a left side view of the packaging container 1. In one embodiment, as shown in FIG. 8, the left opening line 25 includes a first portion 25a, a second portion 25b, and a third portion 25c disposed between the first portion 25a and the second portion 25b. One end of the first portion 25a is connected to one end of the front opening line 23 on the boundary portion 31, and the other end of the first portion 25a is connected to one end of the third portion 25c. One end of the second portion 25b is connected to one end of the rear opening line 24 on the boundary portion 33, and the other end of the second portion 25b is connected to the other end of the third portion 25c.

[0056] The third part 25c is formed at a position shifted in the vertical direction Z with respect to the first part 25a and the second part 25b. In the embodiment shown in FIG. 8, the third part 25c is disposed below the first part 25a and the second part 25b. Note that the third part 25c may be disposed above the first part 25a and the second part 25b. By disposing the third part 25c at a position shifted in the vertical direction Z with respect to the first part 25a and the second part 25b, the left panel 15 can be pressed directly above or below the third part 25c, and the packaging container 1 can be easily opened along the opening line 20 starting from the third part 25c. In one embodiment, the third part 25c may be formed at the same height position as the first part 25a and the second part 25b in the vertical direction Z.

[0057] As shown in FIG. 1, in the vertical direction Z, the front opening line 23, the rear opening line 24, and the right opening line 26 are disposed at the same height position. Also, the first part 25a and the second part 25b of the left opening line 25 are disposed at the same height position as the front opening line 23, the rear opening line 24, and the right opening line 26. Therefore, the opening line 20 is disposed at the same height position on the boundary portions 31, 32, 33, 34.

[0058] In one embodiment, the opening line 20 is formed below (on the side of the bottom panel 11) the center line of the packaging container 1 in the vertical direction Z. That is, the height position of the opening line 20 on the boundary portions 31, 32, 33, 34 is disposed below the center line of the packaging container 1 in the vertical direction Z. Note that when the height positions of the front opening line 23, the rear opening line 24, the left opening line 25, and the right opening line 26 are different, the height position of the opening line 20 means the lowest position among the height positions of the opening line 20 on the boundary portions 31, 32, 33, 34. In another embodiment, the opening line 20 may be disposed above (on the side of the front panel 13) the center line of the packaging container 1 in the vertical direction Z.

[0059] In one embodiment, stopper pieces 35 for supporting a plurality of pet sheets 2 inside the packaging container 1 may be formed on the front panel 13 and the back panel 14 of the packaging container 1. As shown in FIG. 1, the stopper piece 35 is formed by breaking the perforations formed in the front panel 13 and the back panel 14, and can be bent into the interior of the packaging container 1 along a bending line 35a extending in the vertical direction Z. The stopper piece 35 is located below the opening line 20 (on the side of the bottom panel 11) in the vertical direction Z. In particular, the upper edge portion of the stopper piece 35 may be located above (on the side of the opening line 20) the intermediate line between the opening line 20 and the bottom panel 11 in the vertical direction Z.

[0060] Note that the stopper piece 35 may be provided on only one of the front panel 13 and the back panel 14. In the embodiment shown in FIG. 1, the stopper piece 35 is formed by breaking a substantially U-shaped perforation opened to the left panel 15 side, but the stopper piece 35 may be formed by breaking a substantially U-shaped perforation opened to the right panel 16 side. Further, the stopper piece 35 may be bendable into the interior of the packaging container 1 along a bending line extending in the width direction X.

[0061] When opening the packaging container 1, the user presses the left panel 15 directly above or below the third portion 25c of the left opening line 25 to break the left opening line 25 starting from the third portion 25c. Then, the opening line 20 is broken over the entire area. As a result, as shown in FIG. 9, the packaging container 1 is separated into a container upper portion 51 including the top panel 12 and a container lower portion 52 including the bottom panel 11.

[0062] As shown in Fig. 9, a plurality of pet sheets 2 are accommodated in the packaging container 1 in an upright posture with the folding line L1 directed in the vertical direction Z. Here, in the vertical direction Z, the opening line 20 is located below the top 2a of the plurality of pet sheets 2 in the upright posture (on the side of the bottom plate 11). Therefore, when the packaging container 1 is divided into an upper container part 51 and a lower container part 52, the upper parts of the plurality of pet sheets 2 accommodated in the packaging container 1 are exposed through the opening 36 formed between the upper container part 51 and the lower container part 52. Therefore, the user can put a finger into the packaging container 1 through the opening 36, pick up the exposed part of the pet sheet 2 from the thickness direction, and take it out from the packaging container 1.

[0063] Fig. 10 is a left side view of the opened packaging container 1. The distance H1 between the opening line 20 and the top 2a of the pet sheet 2 in the vertical direction Z is smaller than the stiffness and flexibility of the double-folded pet sheet 2. As shown in Fig. 10, the distance H1 between the opening line 20 and the top 2a of the pet sheet 2 in the vertical direction Z corresponds to the height of the exposed part of the pet sheet 2 when the packaging container 1 is opened. In other words, the distance H1 is the difference between the height H2 of the upright pet sheet 2 with the bottom plate 11 as a reference and the height H3 of the opening line 20 with the bottom plate 11 as a reference. Although not limited, the distance H1 between the opening line 20 and the top 2a of the pet sheet 2 in the vertical direction Z is, for example, 50.2 mm or more and 95.2 mm or less.

[0064] The stiffness and flexibility is an index indicating bending resilience, and is measured using a stiffness and flexibility tester (for example, the stiffness and flexibility tester CAN-1MCA manufactured by Dai-ichi Kagaku Seiki Co., Ltd.) conforming to the JIS L 1096 A method (45° cantilever method). Specifically, the stiffness and flexibility of the double-folded pet sheet 2 can be measured as follows. First, a test piece of 30 mm × 100 mm is cut out from the absorption part 10a of the double-folded pet sheet 2, and the test piece is set on a table having a 45° inclined plane. Next, the test piece is pushed out at a speed of 5 mm / second, and the pushing distance when the angle with respect to the horizontal plane becomes 150° is measured. Then, the measured pushing distance is taken as the stiffness and flexibility.

[0065] As described above, in the packaging container 1, since the distance H1 between the opening line 20 and the top 2a of the PET sheet 2 in the vertical direction Z is smaller than the stiffness of the double-folded PET sheet 2, when the packaging container 1 is opened, the PET sheet 2 is prevented from sagging and bending over the lower part 52 of the container, and the standing posture is maintained. Therefore, in this packaging container 1, the PET sheet 2 can be easily taken out.

[0066] Incidentally, the distance H1 between the opening line 20 and the top 2a of the PET sheet 2 in the vertical direction Z may be larger than the stiffness of the PET sheet 2 in the unfolded state (before folding). In this case, since the exposed portion of the PET sheet 2 when the packaging container 1 is opened can be increased, it can be easily taken out from the packaging container 1.

[0067] FIG. 11 is a top view of the opened packaging container 1. As shown in FIG. 11, the plurality of PET sheets 2 are arranged side by side in the width direction X inside the packaging container 1 in a state of being double-folded so that the back sheet 42 is disposed inside. In one embodiment, the plurality of PET sheets 2 may be arranged in two rows. In the embodiment shown in FIG. 11, the plurality of PET sheets 2 include a plurality of PET sheets 2A in the first row arranged in the width direction X and a plurality of PET sheets 2B in the second row arranged in the width direction X. The plurality of PET sheets 2A in the first row and the plurality of PET sheets 2B in the second row are arranged adjacent to each other in the depth direction Y and are aligned in the depth direction Y, respectively.

[0068] The plurality of pet sheets 2A in the first column and the plurality of pet sheets 2B in the second column are arranged in the packaging container 1 with their folding lines L1 butted against each other. That is, the folding line L1 of the plurality of pet sheets 2A in the first column and the folding line L1 of the plurality of pet sheets 2B in the second column are opposed to each other. By accommodating the plurality of pet sheets 2 in this way, it is possible to prevent the hook-and-loop fasteners 48 of the plurality of pet sheets 2A in the first column from sticking to the surface sheets 41 of the plurality of pet sheets 2B in the second column, and it is possible to prevent the hook-and-loop fasteners 48 of the plurality of pet sheets 2B in the second column from sticking to the surface sheets 41 of the plurality of pet sheets 2A in the first column. Therefore, since the plurality of pet sheets 2A in the first column and the plurality of pet sheets 2B in the second column are prevented from being joined, the pet sheets 2 can be individually taken out from the packaging container 1.

[0069] When several pet sheets 2 are taken out from the packaging container 1 and the remaining number of pet sheets 2 decreases, the user moves the plurality of pet sheets 2 in the packaging container 1 to the left panel 15 side as shown in FIG. 12, and bends the stopper pieces 35 formed on the front panel 13 and the back panel 14 along the folding line 35a into the interior of the packaging container 1. At this time, the stopper piece 35 bent into the interior of the packaging container 1 contacts the absorption portion 10a of the pet sheet 2 in the packaging container 1, and the pet sheet 2 is supported by the stopper piece 35. As a result, the pet sheet 2 is prevented from falling down in the packaging container 1.

[0070] As described above, in the packaging container 1 described above, since the unsealing line 20 is located on the side of the bottom plate 11 rather than on the top 2a of the plurality of PET sheets 2 in the standing posture, when the packaging container 1 is unsealed along the unsealing line 20 and the upper part 51 of the container is separated from the lower part 52 of the container, the upper parts of the plurality of PET sheets 2 are exposed from the packaging container 1 through the opening 36. Therefore, the user can put a finger into the packaging container 1 through the opening 36, pick up the PET sheet 2 from the thickness direction, and take it out of the packaging container 1. On the other hand, since each of the plurality of PET sheets 2 is folded in half along the folding line L1, it is not easy to fall in the packaging container 1. In particular, since the distance H1 between the unsealing line 20 and the top 2a of the PET sheet 2 in the vertical direction Z is smaller than the stiffness and flexibility of the folded PET sheet 2, the PET sheet 2 is prevented from leaning against the lower part 52 of the container and bending. Therefore, since the standing posture of the PET sheet 2 is maintained, according to this packaging container 1, the PET sheet 2 can be easily taken out.

[0071] In addition, in the embodiments shown in FIGS. 9 to 12, the plurality of PET sheets 2 are arranged in the packaging container 1 in a state of being folded in half so that the back sheet 42 is arranged inside. However, when the back sheet 42 is made of a resin film, the plurality of PET sheets 2 may be arranged in the packaging container 1 in a state of being folded in half so that the front sheet 41 is arranged inside. Since it is difficult to attach the hook-and-loop fastener 48 to the resin film, even when the plurality of PET sheets 2 are arranged side by side in the width direction X inside the packaging container 1 in a state of being folded in half so that the back sheet 42 is arranged inside, the hook-and-loop fastener 48 is prevented from being attached to the back sheet 42 of another PET sheet 2.

[0072] Next, a packaging container according to another embodiment will be described. FIG. 13 is a perspective view showing a packaging container 1A according to another embodiment. Hereinafter, the differences from the packaging container 1 shown in FIG. 1 will be mainly described, and overlapping descriptions will be omitted.

[0073] As shown in FIG. 13, the right opening line 26 formed on the right panel 16 of the packaging container 1A is disposed above (toward the top panel 12 side) the left opening line 25 formed on the left panel 15. Accordingly, the front opening line 23 and the rear opening line 24 of the packaging container 1A are inclined and extend in the depth direction Y so as to go upward as they approach the right opening line 26.

[0074] When the user opens the packaging container 1A along the opening line 20, as shown in FIG. 14, the packaging container 1A is separated into an upper container portion 51 including the top panel 12 and a lower container portion 52 including the bottom panel 11. At this time, since the front opening line 23 and the rear opening line 24 are inclined, the height of the lower container portion 52 in the vertical direction Z increases from the left panel 15 toward the right panel 16. In this packaging container 1A, when the number of the pet sheets 2 accommodated therein is large, the user can easily take out the pet sheets 2 from the left panel 15 side. On the other hand, when the pet sheets 2 are sequentially taken out from the left panel 15 side and the number of the pet sheets 2 accommodated in the packaging container 1A decreases, the pet sheets 2 are supported by the right panel 16 and are less likely to fall down. Therefore, it becomes easier to maintain the standing posture of the right panel 16.

[0075] Next, a packaging container according to still another embodiment will be described. FIG. 15 is a perspective view showing a packaging container 1B according to another embodiment. Hereinafter, differences from the packaging container 1 shown in FIG. 1 will be mainly described, and redundant descriptions will be omitted.

[0076] As shown in FIG. 15, the packaging container 1B accommodates a plurality of pet sheets 3. The plurality of pet sheets 3 accommodated in the packaging container 1B are not folded and are arranged in the width direction X in the packaging container 1B in a standing posture with their thickness direction oriented in the width direction X. FIG. 16 is a schematic cross-sectional view of the pet sheet 3. As shown in FIG. 16, the pet sheet 3 is different from the pet sheet 2 in that it further includes an adhesive layer 46 and a release sheet 47 in addition to a front sheet 41, a back sheet 42, and an absorber 43.

[0077] The adhesive layer 46 is provided so as to cover the outer surface 42a of the back sheet 42. The release sheet 47 covers the back sheet 42 via the adhesive layer 46. In this PET sheet 3, by peeling off the release sheet 47, the back sheet 42 can be attached onto the processing sheet 100 by the adhesive force of the adhesive layer 46.

[0078] A plurality of PET sheets 3 are accommodated in the packaging container 1B in an upright posture with the release sheet 47 not peeled off. FIG. 17 is a left side view of the opened packaging container 1B. As shown in FIG. 17, the distance H1 between the opening line 20 in the vertical direction Z and the top 3a of the PET sheet 3 is smaller than the rigidity and flexibility of the PET sheet 3 with the release sheet 47. Although the PET sheet 3 is not folded in half unlike the PET sheet 2, the rigidity and flexibility are increased by the provision of the release sheet 47. As described above, since the distance H1 between the opening line 20 in the vertical direction Z and the top 3a of the PET sheet 3 is smaller than the rigidity and flexibility of the PET sheet 3, when the packaging container 1B is opened, the PET sheet 3 is prevented from leaning against the lower part 52 of the container and bending, and the upright posture is maintained.

[0079] Incidentally, the distance H1 between the opening line 20 in the vertical direction Z and the top 3a of the PET sheet 3 may be larger than the rigidity and flexibility of the PET sheet 3 with the release sheet 47 peeled off. In this case, when the packaging container 1B is opened along the opening line 20, the exposed portion of the PET sheet 3 can be enlarged, so that the PET sheet 3 can be easily taken out from the packaging container 1B by pinching it in the thickness direction.

[0080] As described above, the packaging containers 1, 1A, and 1B according to various embodiments have been described. However, the present invention is not limited to the above-described embodiments, and various modifications can be configured without changing the gist of the invention. That is, it should be noted that the above-described embodiments are for illustrative purposes and do not limit the scope of the present invention.

[0081] For example, in the above embodiment, the packaging containers 1, 1A, and 1B contain the PET sheets 2 and 3, but the absorbent sheets contained in the packaging containers 1, 1A, and 1B are not limited to the PET sheets 2 and 3. For example, the processing sheet 100 may be contained.

[0082] As shown in FIG. 18, the opening line 20 may be a so-called double zipper type of sewing line including a pair of upper and lower sewing lines 20a and 20b and a zipper portion 20c formed between the pair of upper and lower sewing lines 20a and 20b. In this case, by pulling the zipper portion 20c, the opening line 20 can be easily broken. When the opening line 20 is a double zipper type of sewing line, as shown in FIG. 18, the sewing line 20a or 20b of the third portion 25c of the left opening line 25 may be formed at a position shifted in the vertical direction Z with respect to the sewing line 20a or 20b of the first portion 25a and the second portion 25b of the left opening line 25. In addition, the above-described various embodiments can be combined within a non-contradictory range.
