[0003] Japanese Patent Application Laid-Open No. 2018-33560

[0004] The usage form of the sheet structure configured as described above is not limited to a form in which the sheet structure is housed in a case and the sheet is taken out and used through a case opening formed in the case, but there is also a form in which it is used as a single sheet structure without being housed in a case. Therefore, in recent years, in consideration of the decorativeness when using the sheet structure alone, a decorative portion such as a pattern is provided on the outer surface of the sheet structure. By providing the decorative portion, the decorative effect of the sheet structure can be enhanced. On the other hand, due to the influence of the design for improving the decorativeness, the designs of the packaging sheet and the lid body are similar, and there are cases where the lid body is difficult for the user to recognize.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a sheet structure that can improve the decorative effect of the outer surface of the sheet structure and is easy for the user to recognize the lid body.

[0006] A sheet structure according to one embodiment comprises a sheet laminate formed by stacking multiple sheets, and a packaging body for packaging the sheet laminate. The packaging body comprises a packaging sheet having an opening that serves as an outlet for the sheets, and a lid that covers the opening in a manner that can be opened and closed. The sheet laminate extends in a planar direction including a first and second direction which are mutually orthogonal, and has an upper surface on which the lid is placed, a lower surface facing the upper surface and extending in the planar direction, and a side surface located between the upper surface and the lower surface and extending in a third direction which is the height direction. The packaging sheet is provided with a toy design section that extends across the upper surface and the side surface and is used as a toy. The outer edge portion along the outer edge of the outer surface of the lid has a single-color region which is a single color different from the adjacent region adjacent to the outer edge of the lid on the packaging sheet. The single-color region is provided in an area of ​​50% or more of the entire outer edge portion.

Figure 3 is a cross-sectional view along the line A-A shown in Figure 2. Figure 4 shows the state in which an opening is formed in the cross-section shown in Figure 3. Figure 5 is a first side view of the sheet structure according to the embodiment. Figure 6 is a third side view of the sheet structure according to the embodiment.

[0008] (1) Outline of Embodiments The following matters will become clear from the description in this specification and the accompanying drawings. The invention according to Embodiment 1 is a sheet structure having a sheet laminate in which a plurality of sheets are stacked, and a packaging body for packaging the sheet laminate. The packaging body has a packaging sheet having an opening which serves as an outlet for the sheets, and a lid which covers the opening so as to be openable and closable. The sheet laminate has an upper surface on which the lid is placed, which extends in a planar direction including a first direction and a second direction which are orthogonal to each other, a lower surface which is opposite to the upper surface and extends in the planar direction, and a side surface which is placed between the upper surface and the lower surface and extends in a third direction which is the height direction. The packaging sheet is provided with a toy design section which extends across the upper surface and the side surface and is used as a toy. The outer edge portion along the outer edge of the outer surface of the lid has a single color region which is a single color different from the adjacent region adjacent to the outer edge of the lid on the packaging sheet. The single color region is provided in a range of 50% or more of the entire outer edge portion. According to this embodiment, the toy design portion extends across the top and sides, making it easy for the user to recognize the toy design portion. The toy design portion is designed to allow the sheet structure to be used as a toy, and in addition to its aesthetic decorative effect, it can provide functionality as a toy. Therefore, the decorative effect of the sheet structure can be enhanced. Furthermore, the outer edge of the lid has a single-color area that is a different single color from the adjacent area adjacent to the lid. Therefore, when the user looks at the top surface, it is easy to distinguish and recognize the packaging sheet and the lid. Also, because the outer edge of the outer edge portion is a single color, the outer edge of the lid stands out more easily compared to a configuration with multiple colors, making it easier for the user to recognize the lid.

[0009] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1: The color difference ΔE between the single-color area and the adjacent area is 19 or more. According to this embodiment, the outer edge of the lid becomes more conspicuous against the surrounding packaging sheet, making it easier for the user to recognize the position and presence of the lid.

[0010] In a preferred embodiment, the invention according to embodiment 3 may have the following features in the invention according to embodiment 2: The color difference ΔE between the single color area and the color applied to the widest area of ​​the packaging sheet on the top surface is 25 or more. According to this embodiment, when a user views the entire top surface, the outer edge of the lid becomes more conspicuous against the surrounding packaging sheet, making it easier for the user to recognize the position and presence of the lid.

[0011] In a preferred embodiment, the invention according to embodiment 4 may have the following features in the invention according to any of embodiments 1 to 3: The length of the sheet structure in the first direction is longer than the length of the sheet structure in the second direction. The side surface has a first side surface and a second side surface that extend in the first and third directions and are opposite to each other, and a third side surface and a fourth side surface that extend in the second and third directions and are opposite to each other. A packaging joint for joining the packaging sheets together is provided along the second direction at the center of the third side surface in the third direction. The toy design portion is arranged to span at least the top surface, the first side surface, and the third side surface. The toy design portion on the top surface has a design that indicates the roof of the vehicle. The toy design portion on the first side surface has a design that indicates the side windows and tires of the vehicle. The toy design portion on the third side surface has a design that indicates the front window of the vehicle. The front window design is arranged on the third side surface only on the top surface side of the packaging joint. According to this embodiment, the toy design section is designed to resemble a vehicle, providing a way to use it as a vehicle toy. Furthermore, since the design of the front window is positioned only on the upper side above the packaging joint, the reduction in the design quality of the front window due to the packaging joint is suppressed, and the design quality as a toy can be improved.

[0012] In a preferred embodiment, the invention according to embodiment 5 may have the following features in the invention according to embodiment 4: The design of the front window is arranged to span the third side surface and the top surface. According to this embodiment, the area of ​​the front window, which is the main design of the toy modeled after a vehicle, can be secured while providing the packaging joints necessary for the function of the sheet structure. In addition, when the user looks at the top surface, they can see a part of the front window, making it easier to recognize that it is a toy modeled after a vehicle.

[0013] In a preferred embodiment, the invention according to embodiment 6 may have the following features in the invention according to embodiment 4 or embodiment 5: The toy design portion is arranged across the second side and the fourth side. The packaging joint is provided along the second direction at the center of the fourth side in the third direction. The toy design portion on the fourth side has a design that represents the rear window of a vehicle. The toy design portion on the second side has a design that represents the side door and side window of the vehicle. The rear window design is arranged on the fourth side only on the upper side of the packaging joint. According to this embodiment, the design that imitates a vehicle is provided on the top surface and the entirety of the first to fourth sides, thereby further improving the design quality as a toy. Therefore, it is possible to make it easier for users to recognize the seat structure as a toy and encourage its use as a toy. In addition, since the rear window design is arranged only on the upper side of the packaging joint, it is possible to suppress the deterioration of the design quality of the rear window due to the packaging joint and improve the design quality as a toy.

[0014] In a preferred embodiment, the invention according to embodiment 7 may have the following features in the invention according to embodiment 6: The design of the rear window is arranged to span the fourth side surface and the top surface. According to this embodiment, the area of ​​the rear window, which is the main design of the toy modeled after a vehicle, can be secured while providing the packaging joints necessary for the function of the seat structure. In addition, when the user looks at the top surface, they can see a part of the rear window, making it easier to recognize that it is a toy modeled after a vehicle.

[0015] 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 lid has an upright region that stands upright with a base end located at the downstream end of the lid as a base point when pulled from the upstream end to the downstream end in the opening direction. The outer surface of the lid is provided with a lid design portion different from the toy design portion and a base end marker portion indicating the position of the base end. The lid design portion and the base end marker portion are different colors from the single color region and the adjacent region, but have the same color as each other. According to this embodiment, because the lid design portion and the base end marker portion are different colors from the single color region and the adjacent region, the lid design portion and the base end marker portion are easily distinguishable from their surroundings and easily stand out. Furthermore, the base end marker portion and the lid design portion have the same color, and their synergistic effect makes it easier to attract the user's attention. The presence of the base end marker portion makes it easier for the user to grasp the position of the base end of the lid.

[0016] In a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to embodiment 8: The color difference ΔE between the lid design portion and the single-color region is greater than the color difference ΔE between the single-color region and the adjacent region. According to this embodiment, since the color difference ΔE between the single-color region and the lid design portion is greater than the color difference ΔE between the single-color region and the adjacent region, the lid design portion attached to the lid is more conspicuous.

[0017] In a preferred embodiment, the invention according to embodiment 10 may have the following features in the invention according to any of embodiments 1 to 9. The lid is configured to stand upright with a base end located at the downstream end of the lid as a pivot point when pulled from the upstream end to the downstream end in the opening direction. The outer surface of the lid is provided with a lid design portion different from the toy design portion and an opening indicator portion indicating the position of the upstream end of the lid in the opening direction. The lid design portion and the opening indicator portion are different colors from the single-color area and the adjacent area, but have the same color as each other. According to this embodiment, because the lid design portion and the opening indicator portion are different colors from the single-color area and the adjacent area, the lid design portion and the opening indicator portion are easily distinguishable from their surroundings and easily stand out. Furthermore, since the opening indicator portion and the lid design portion have the same color, they easily attract the user's attention through a synergistic effect. The presence of the opening indicator portion makes it easier for the user to grasp the opening position of the lid.

[0018] (2) Configuration of the Sheet Structure The sheet structure 1 according to the embodiment will be described below with reference to the drawings. In the following drawings, the same 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 etc. may differ from those in reality. Therefore, specific dimensions etc. 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.

[0019] Figure 1 is a perspective view of the sheet structure 1. Figure 2 is a view showing the top surface 15 of the sheet structure 1. Figure 3 is a cross-sectional view along the line A-A shown in Figure 2. Figure 4 is a view showing the state in which the opening 7 is formed in the cross-section shown in Figure 3. Figure 5 is a view showing the first side surface 11 of the sheet structure 1 according to the embodiment. Figure 6 is a view showing the third side surface 13 of the sheet structure 1 according to the embodiment. The sheet structure 1 includes a sheet laminate 50 in which a plurality of sheets 51 are stacked, and a packaging body 20 that packages the sheet laminate 50. The packaging body 20 includes a packaging sheet 21 having an opening 7 that serves as an outlet for the sheets 51, and a lid 22 that can open and close to cover the opening 7.

[0020] The sheet structure 1 has an upper surface 15 and a lower surface 16 that face each other. The upper surface 15 and the lower surface 16 are surfaces that extend in a planar direction including a first direction D1 and a second direction D2 which are perpendicular to each other. The length of the sheet structure 1 in the first direction D1 may be longer than the length of the sheet structure 1 in the second direction D2. In this embodiment, the first direction D1 extends in the lateral direction, and the second direction D2 extends in the vertical direction. The upper surface 15 and the lower surface 16 are spaced apart in a third direction D3 which is the height direction. The third direction D3 is perpendicular to the first direction D1 and the second direction D2. The upper surface 15 is the surface on which the lid 22 is placed. The lower surface 16 is the surface that faces the upper surface 15.

[0021] The sheet structure 1 has a side surface that connects the upper surface 15 and the lower surface 16 and extends in a third direction D3. The side surface may have a first side surface 11 and a second side surface 12 that extend in a first direction D1 and a third direction D3 and are opposite to each other, and a third side surface 13 and a fourth side surface 14 that extend in a second direction D2 and a third direction D3 and are opposite to each other. A packaging joint 5 for joining the packaging sheets 21 together may be provided along the second direction D2 at the center of the third side surface 13 and the fourth side surface 14 in the third direction D3. The sheet structure 1 may be a substantially rectangular parallelepiped. Each surface may be a rectangular surface. Also, each surface may not intersect perpendicularly at its boundary, but rather in a curved manner.

[0022] The sheets 51 of the sheet laminate 50 may be wet sheets containing moisture (e.g., wet wipes) or dry sheets not containing moisture. In this embodiment, the sheets 51 are wet wipes. The sheet laminate 50 may be folded at least along a crease in the first direction D1. In the folded state, adjacent sheets 51 may be arranged alternately in the thickness direction. In the state where it is housed in the packaging 20 (in this embodiment, folded along a crease in the first direction D1), the length of the sheet laminate 50 in the first direction D1 may be longer than the length of the sheet laminate 50 in the second direction D2. In a modified example, the length of the sheet laminate 50 in the first direction D1 may be the same as the length of the sheet laminate 50 in the second direction D2, or it may be shorter than the length of the sheet laminate 50 in the second direction D2. Furthermore, the sheet 51 may be folded using a crease extending in the second direction D2 as a base point, or it may be stacked without being folded using a crease as a base point, or it may be composed of continuous sheets and configured to be partially detachable via perforations.

[0023] The packaging body 20 contains a sheet laminate 50. The packaging body 20 has a packaging sheet 21 and a lid 22. The packaging sheet 21 may be made of a resin film such as a polyolefin resin or a polyester resin. The packaging sheet 21 may have an opening 7 which serves as an outlet for the sheet 51. The opening 7 may be a portion surrounded by a cut portion CP (see Figure 3). The cut portion CP may be made of a fragile portion such as a perforation or a cutting line. The cut portion CP may form the outer edge of the opening 7.

[0024] The opening 7 may be located on the upper surface 15. That is, the surface on which the opening 7 is formed may constitute the upper surface 15. The dimensions of the opening 7 should be such that each sheet 51 can be pulled out. The shape of the opening 7 is not limited; in plan view, it may be elliptical, horizontally (vertically) elongated, or perfectly circular. Preferably, the shape of the opening 7 is curved and does not have sharp corners in order to prevent the sheet 51 from getting caught. The opening 7 may be located in the center of the second direction D2 and the center of the first direction D1 of the sheet structure 1.

[0025] The lid 22 is configured to cover the opening 7 in a way that allows it to be opened and closed. The lid 22 has a larger area than the opening 7. When the lid 22 is pulled from the upstream side to the downstream side in the opening direction D4, the region R10 of the packaging sheet 21 surrounded by the cut portion CP is separated via the cut portion CP surrounding the opening 7, and the opening 7 is formed. Figure 4 shows the state in which the opening 7 is formed in the cross-section shown in Figure 3. An adhesive layer 24 having an adhesive material is attached to the surface of the lid 22 facing the packaging sheet 21, and the lid 22 may be removably bonded to the packaging sheet 21. In this embodiment, the sheet structure 1 has a cut portion CP formed on the packaging sheet 21, and when the lid 22 is pulled away from the packaging sheet 21 during use, the region R10 surrounded by the cut portion CP on the packaging sheet 21 is separated and peeled off together with the lid 22. This forms the opening 7. In other words, in this embodiment, the sheet structure 1 has an opening 7 that is exposed when the lid 22 is pulled by the user during use.

[0026] The opening 7 may be exposed by the lid 22 separating from the upper surface 15, or the opening 7 may be exposed by the other part (upright region 26) of the lid 22 separating from the upper surface 15 while a part of the lid 22 (base end 25) remains separated from the upper surface 15. The lid 22 of this embodiment has an upright region 26 that stands upright with the base end 25 located at the downstream end of the lid 22 as the pivot point when pulled from the upstream end to the downstream end in the opening direction D4 (see Figure 3). The opening direction D4 of the lid of this embodiment is along the first direction D1. Figure 3 shows the range of the base end 25 and the upright region 26 in the first direction D1.

[0027] The sheet structure 1 of this embodiment is configured to improve the decorative effect of the outer surface of the sheet structure 1 and to make it easy for the user to recognize the lid 22. Next, the configuration that improves the decorative effect of the outer surface of the sheet structure 1 and makes it easy for the user to recognize the lid 22 will be described in detail. The packaging sheet 21 is provided with a toy design section 80 that extends across the top surface 15 and the sides and is used as a toy. The toy design section 80 is a design that makes the sheet structure 1 usable as a toy, and it may be a design that allows the user to play with it as a toy by looking at the design, or it may be a design that allows the user to pick up the sheet structure 1 and play with it as a toy. The design of this embodiment is a design that imitates an automobile as a vehicle, and more specifically, a design that imitates a patrol car.

[0028] The toy design portion 80 of the sheet structure 1 in this embodiment extends across the top surface 15 and the side surface. The toy design portion 80 only needs to be provided on at least one of the first side surface 11 to the fourth side surface 14, and preferably on all of the first side surface 11 to the fourth side surface 14. The top surface 15 has an opening 7 and is a surface that is easily visible to the user. Because the toy design portion 80 extends across the top surface 15 and the side surface, the user can easily recognize the toy design portion 80. Furthermore, because the toy design portion 80 is provided over a wide area that extends across the top surface 15 and the side surface, the user can recognize the toy design portion 80 even more easily. The toy design portion 80 is a design intended for the sheet structure 1 to be used as a toy, and in addition to its aesthetic decorative effect, it can provide a toy function. Therefore, the decorative effect of the sheet structure 1 can be enhanced.

[0029] The lid 22 has an outer edge portion 29 that runs along the outer edge 22E on the outer surface of the lid 22. The outer surface of the lid 22 is the surface facing outward on the lid 22, and is the opposite surface to the inner surface that faces the packaging sheet 21. The outer edge portion 29 is a region that extends along the outer edge on the outer surface of the lid 22. Specifically, the outer edge portion may be a range of 5 mm inward from the outer edge 22E on the outer surface of the lid 22. In Figure 2, a dashed line is drawn along the outer edge of the outer edge portion 29. Note that the outer edge of the outer edge portion 29 is the outer edge 22E of the lid 22.

[0030] The outer edge portion 29 has a single-color region RC in the packaging sheet 21 that is a single color different from the adjacent region 28 adjacent to the outer edge of the lid 22. The adjacent region 28 is a certain range from the outer edge 22E of the lid 22, and specifically, it may be a range of 5 mm outward from the outer edge 22E. In Figure 2, a dashed line is drawn along the outer edge of the adjacent region 28. The color of the single-color region RC is different from any of the colors applied to the adjacent region 28. Also, a single color is a single color that is not mixed with any other color. The single-color region RC may include areas that are slightly different in color due to printing inconsistencies, and specifically, areas where the color difference ΔE, described later, is 3.0 or less are included in the single-color region. The single-color region RC is provided in an area of ​​50% or more of the entire outer edge portion 29. That is, the area of ​​the single-color region RC in relation to the total area of ​​the outer edge portion 29 is 50% or more and 100% or less.

[0031] In this embodiment, the outer edge portion 29 is painted white and blue, and both colors are different from the colors of the adjacent region 28, but more than 50% of the outer edge portion 29 is painted white. The blue is applied to the base end marker portion 92, which will be described later. The white is applied to the region other than the base end marker portion 92. Therefore, the region painted white constitutes a single-color region RC. In this embodiment, the adjacent region 28 is painted with colors other than white and blue. Specifically, the adjacent region 28 is painted gray in the portion 81 which is the color of the roof base, and red in the portion 82 which is modeled after the red light of a patrol car.

[0032] The outer edge 29 of the lid 22 has a single-color area RC that is a different single color from the adjacent area 28 adjacent to the lid 22. Therefore, when a user looks at the top surface 15, it is easier to distinguish and recognize the packaging sheet 21 and the lid 22. In addition, because the outer edge 29 has a single color, the outer edge 29 of the lid 22 is more conspicuous compared to a configuration with multiple colors, making it easier for the user to recognize the lid 22.

[0033] The following describes a preferred configuration in this embodiment. The sheet structure according to this embodiment may or may not have the following configuration. The color difference ΔE between the single color area RC and the adjacent area 28 may be 19 or more, and preferably 25 or more. When the color difference ΔE between the single color area RC and the adjacent area 28 is 19 or more, the outer edge 29 of the lid 22 becomes more conspicuous against the surrounding packaging sheet 21, making it easier for the user to recognize the position and presence of the lid 22.

[0034] The color difference ΔE is calculated by acquiring image data (JPEG) for two points to be measured, quantifying each point from the image data based on the CIE 1976 (L*a*b*) color space as defined in Z 8781-4:201, and determining that when the difference in L* values ​​between the two points is ΔL*, the difference in a* is Δa*, and the difference in b* values ​​is Δb*, then the color difference ΔE = [(ΔL*) 2 +(Δa*) 2 +(Δb*) 2 ] 1 / 2 It is determined by [method].

[0035] The color difference ΔE between a single-color region RC and an adjacent region 28 is measured as follows: If a single color is assigned to both the single-color region RC and the adjacent region 28, an arbitrary point in each region is quantified based on the CIE 1976 (L*a*b*) color space, and the color difference ΔE is measured. If at least one of the single-color region RC and the adjacent region 28 is not assigned a single color, then in that region, 10 points at 5 mm intervals are quantified based on the CIE 1976 (L*a*b*) color space. The smallest value among the color differences ΔE calculated based on the 10 quantified values ​​is adopted as the color difference ΔE between the single-color region RC and the adjacent region 28.

[0036] The color difference ΔE between the single color region RC and the color applied to the largest area on the packaging sheet 21 of the top surface 15 may be 25 or more. The color applied to the largest area on the packaging sheet 21 of the top surface 15 is the color applied to the largest area on the top surface 15 that is not covered by the lid 22. In this embodiment, the color applied to the largest area is the color of the base portion 81 of the vehicle's roof. In this embodiment, when a user views the entire top surface 15, the outer edge 29 of the lid 22 becomes more conspicuous compared to the surrounding packaging sheet 21, making it easier for the user to recognize the position and presence of the lid 22.

[0037] The toy design section 80 may be positioned across at least the top surface 15, the first side surface 11, and the third side surface 13. The toy design section 80 on the top surface 15 may have a design that represents the roof of a vehicle. In this embodiment, the design representing the roof of a vehicle on the top surface 15 has a portion 81 that is colored to match the base of the roof and a portion 82 that mimics the red light of a patrol car. The color difference ΔE between the portion 82 that mimics the red light of a patrol car and the single-color area RC is greater than the color difference ΔE between the portion 81 that is colored to match the base of the roof and the single-color area RC, making the red light of the patrol car more conspicuous. Because the red light of the patrol car is more conspicuous, users can easily notice the presence of the red light, which is a characteristic of a patrol car, and easily recognize that it is a toy that mimics a patrol car.

[0038] The toy design section 80 on the first side surface 11 may have a design 83 indicating the vehicle's side window and a design 84 indicating the tires. The toy design section 80 on the first side surface 11 may also have a section 85 with the base color of the vehicle's side portion. The section 85 with the base color of the vehicle's side portion is the same color as the section 81 with the base color of the roof on the top surface 15 and may be continuous with the section 81 with the base color of the roof on the top surface 15. This configuration allows for an integrated design that spans the top surface 15 and the first side surface 11.

[0039] The toy design portion 80 on the third side surface 13 may have a design 86 showing the front window of the vehicle. The design 86 of the front window may be arranged only on the upper surface 15 side of the packaging joint portion 5 on the third side surface 13. That is, the design 86 of the front window does not straddle the packaging joint portion 5 and is not arranged on the lower surface 16 side of the packaging joint portion 5. According to this aspect, it is possible to suppress the deterioration of the design property of the front window due to the packaging joint portion 5 and improve the design property as a toy.

[0040] The design 86 of the front window may be arranged straddling the third side surface 13 and the upper surface 15. According to this aspect, while providing the packaging joint portion 5 necessary for the function of the seat structure 1, it is possible to secure the area of the front window which is the main design of the toy imitating the vehicle. In addition, when the user visually recognizes the upper surface 15, a part of the front window can be visually recognized, and it is easier to grasp that it is a toy imitating a vehicle.

[0041] The toy design portion 80 on the third side surface 13 may have a portion 87 with the base color of the front part of the vehicle. The portion 87 with the base color of the front part of the vehicle has the same color as the portion 81 with the base color of the roof on the upper surface 15 and may be continuous with the portion 81 with the base color of the roof. According to this configuration, it is possible to show an integrated design straddling the upper surface 15 and the third side surface 13.

[0042] Preferably, the toy design portion 80 may also be arranged straddling the second side surface 12 and the fourth side surface 14. That is, the toy design portion 80 may be arranged straddling the upper surface 15 and from the first side surface 11 to the fourth side surface 14. According to this aspect, it will have a design imitating a vehicle over the entire upper surface 15 and from the first side surface 11 to the fourth side surface 14, and the design property as a toy can be further improved. The toy design portion 80 of the present embodiment is also arranged on the lower surface 16. However, the toy design portion 80 may not be arranged on the lower surface 16.

[0043] The toy design portion 80 on the second side surface 12 may have a design 83 showing the side window of the vehicle and a design 84 showing the tire, similar to the first side surface 11.

According to this configuration, an integrated design spanning the upper surface 15 and the second side surface 12 can be shown.

[0044] The toy design portion 80 on the fourth side surface 14 may have a design 88 of the rear window. The design 88 of the rear window may be arranged only on the upper surface 15 side of the packaging joint portion 5 on the fourth side surface 14. According to this aspect, it is possible to suppress a decrease in the design property of the rear window due to the packaging joint portion 5 and improve the design property as a toy.

[0045] The design 88 of the rear window may be arranged across the fourth side surface 14 and the upper surface 15. According to this aspect, while providing the packaging joint portion 5 necessary for the function of the seat structure 1, it is possible to secure the area of the rear window, which is the main design of the toy imitating the vehicle. In addition, when the user views the upper surface 15, a part of the rear window can be viewed, and it is easier to recognize that it is a toy imitating the vehicle.

[0046] The fourth side surface 14 may have a portion 89 colored with the base color of the rear portion of the vehicle. The portion 89 colored with the base color of the rear portion of the vehicle may be the same color as the portion 81 colored with the base color of the roof on the upper surface 15 and may be continuous with the portion 81 colored with the base color of the roof on the upper surface 15. According to this configuration, an integrated design spanning the upper surface 15 and the fourth side surface 14 can be shown.

[0047] The outer surface of the lid 22 may be provided with a lid design section 91, which has a different design from the toy design section 80, and a base end marker section 92, which indicates the position of the base end 25. The lid design section 91 only needs to have a different design from the toy design section 80, and may consist of pictures, letters, patterns, etc. In this embodiment, the lid design section 91 is letters indicating the product name. The lid design section 91 may be spaced apart from the outer edge of the lid 22. Because the lid design section 91, which is different from the toy design section 80 of the packaging sheet 21, is provided on the lid 22, the presence of the lid design section 91 makes the lid 22 more noticeable. Also, because the lid design section 91 is spaced apart from the outer edge of the lid 22, it is easy to distinguish between the toy design section 80 and the lid design section 91, making it easier for the user to recognize each design.

[0048] The base end marker portion 92 is an indicator showing the position of the base end portion 25 and may be positioned spaced apart from the lid design portion 91. The base end marker portion 92 only needs to indicate the position of the base end portion 25 and may or may not overlap with the base end portion 25. In this embodiment, the base end marker portion 92 is positioned adjacent to the upstream end of the base end portion 25 in the opening direction D4 without overlapping with the base end portion 25, and is in a straight line extending in the second direction D2. The lid design portion 91 and the base end marker portion 92 may have different colors from the single color area RC and the adjacent area 28, but may have the same color as each other. The same color that the lid design portion 91 and the base end marker portion 92 have is different from the single color area RC and different from the adjacent area 28. According to this embodiment, since the lid design portion 91 and the base end marker portion 92 are different colors from the single color area RC and the adjacent area 28, the lid design portion 91 and the base end marker portion 92 are easily distinguishable from their surroundings and easily stand out. Furthermore, since the base end marker portion 92 and the lid design portion 91 have the same color, they easily attract the user's attention through their synergistic effect. The user can easily grasp the position of the base end portion 25. In this embodiment, the lid design portion 91 and the base end marker portion 92 may have the same color as at least a part of the base end marker portion 92, or at least a part of the lid design portion 91 may have the same color as the base end marker portion 92. Preferably, the main color of the base end marker portion 92 (the color applied to the largest area) may be the same as the main color of the lid design portion 91. Furthermore, in the modified form, the lid design portion 91 may be a different color from the single-color area RC and the adjacent area 28, and the base end marker portion 92 may be a different color from the single-color area RC and the adjacent area 28, and the lid design portion 91 and the base end marker portion 92 may be different colors.

[0049] The color difference ΔE between the lid design portion 91 and the single-color area RC may be greater than the color difference ΔE between the single-color area RC and the adjacent area 28. According to this embodiment, since the color difference ΔE between the single-color area RC and the lid design portion 91 is greater than the color difference ΔE between the single-color area RC and the adjacent area 28, the lid design portion 91 attached to the lid 22 is more conspicuous. Therefore, if the lid design portion 91 is text indicating the product name, brand name, usage precautions, etc., the text becomes easier for the user to read.

[0050] Furthermore, the outer surface of the lid 22 may be provided with a lid design section 91 that is different from the toy design section 80, and an opening indicator section 93 that indicates the position of the upstream end in the opening direction D4 of the lid 22. The lid design section 91 and the opening indicator section 93 may be different in color from the single color area RC and the adjacent area 28, but may have the same color as each other. According to this embodiment, since the lid design section 91 and the opening indicator section 93 are different in color from the single color area RC and the adjacent area 28, the lid design section 91 and the opening indicator section 93 are easily distinguishable from their surroundings and easily stand out. Moreover, since the opening indicator section 93 and the lid design section 91 have the same color, they easily attract the user's attention through a synergistic effect. The presence of the opening indicator section 93 makes it easier for the user to grasp the opening position of the lid 22. In this embodiment, the opening indicator section 93 is triangular in shape and points to the upstream end in the opening direction D4. Furthermore, in the modified form, the lid design portion 91 may be a different color from the single-color area RC and the adjacent area 28, and the opening indicator portion 93 may be a different color from the single-color area RC and the adjacent area 28, and the lid design portion 91 and the opening indicator portion 93 may be different colors.
