Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, from the viewpoint of resource saving, it is desired to efficiently form a storage box from a pattern paper punched out from a sheet material, including a mechanism such as a pop-up mechanism.

[0006] For example, in the packaging box described in Patent Document 1, the card, which has a three-dimensional decorative section with a pop-up mechanism, is manufactured separately from the top flap of the box body. Therefore, the packaging box described in Patent Document 1 is provided with a backing for attaching the card to the top flap. Moreover, the packaging box described in Patent Document 1 has not only a top flap but also an inner flap for attaching the backing. For this reason, there is room for resource conservation in the packaging box described in Patent Document 1.

[0007] The objective of this invention is to provide a storage box that allows for flexibility in the design of the pop-up section while also conserving resources. [Means for solving the problem]

[0008] The inventors of this invention investigated a storage box that would allow for flexibility in the design of the pop-up section while also conserving resources. After diligent investigation, the inventors arrived at the following configuration.

[0009] A storage box according to an embodiment of the present invention comprises a box-shaped storage section formed by folding a sheet material, having a bottom and a plurality of side sections arranged to surround the bottom, forming an opening that opens upward; and a lid section connected to the upper end of one of the plurality of side sections, which rotates relative to the one side section so as to cover the opening, with the connection portion with the side section as the pivot axis. The plurality of side sections each include an outer plate constituting the outer surface of the storage section, an inner plate constituting the inner surface of the storage section at a predetermined distance from the outer plate, and an edge plate extending from the upper end of the outer plate to the upper end of the inner plate. In the storage box, the lid section is connected to the edge plate of one of the side sections. The storage box comprises a pop-up section connected to the edge plate of the one side section to which the lid section is connected, at a position away from the lid section in the thickness direction of the one side section, and a support section connecting the lid section and the pop-up section. The pop-up section is configured to be rotatable relative to the one side section with the connection portion with the edge plate as the pivot axis. The support portion is configured to be rotatable relative to the lid portion with the connection portion to the lid portion as a pivot axis, and is configured to be rotatable relative to the pop-up portion with the connection portion to the pop-up portion as a pivot axis. In the storage box, the lid portion, the edge plate, the pop-up portion, and the support portion constitute a parallel link mechanism.

[0010] In the configuration described above, the storage box consists of a storage section with thick sides and a lid. The lid has a pop-up section, which is part of a lifting mechanism that utilizes the thickness of the sides. The lid and the pop-up section are connected to an edge plate that connects the upper end of the inner plate and the upper end of the outer plate of the side. In other words, the pop-up section is located between the lid and the side plate of the side. Furthermore, a parallel link mechanism, which is a lifting mechanism, is formed by the lid, edge plate, pop-up section, and support section. The pop-up section, which is part of the parallel link mechanism, is configured such that the angle of the lid relative to the edge plate and the angle of the pop-up section relative to the edge plate are equal. Therefore, when the lid is closed, the pop-up section folds planarly so as to approach the surface of the lid.

[0011] In this design, when the lid is opened, the pop-up section can be raised to a height equal to the gap between the lid and the edge plate, within the width of the edge plate. Furthermore, when the lid is closed, the pop-up section folds down to be flush with the lid, thus securing storage space in the storage compartment. This allows for securing storage space in the storage compartment while maintaining the design flexibility of the pop-up section.

[0012] Furthermore, the parallel link mechanism of the pop-up section is integrally formed by the lid, edge plate, pop-up section, and support section. In other words, the lid and edge plate also serve as part of the parallel link mechanism. This allows for space to be secured for the parallel link mechanism by increasing the thickness of the sides that constitute the storage section, and by configuring the lid and part of the storage section as part of the parallel link mechanism, space and resources can be saved.

[0013] As a result, we can provide a storage box that allows for flexibility in the design of the pop-up section while also conserving resources.

[0014] From another perspective, the storage box of the present invention preferably includes the following configuration: The pop-up portion is connected to a position closer to the inner plate than the lid portion. The support portion is connected to the inner surface of the lid portion.

[0015] In the above configuration, the pop-up section is located on the inner surface of the lid. Therefore, when the lid is closed, the pop-up section folds flat between the lid and the storage section, approaching the inner surface of the lid. Thus, a storage box can be provided that allows for greater design flexibility of the pop-up section without compromising the storage space of the storage section when the lid is closed.

[0016] From another perspective, the storage box of the present invention preferably includes the following configuration: The pop-up portion is connected to a position closer to the outer plate than the lid portion. The support portion is connected to the outer surface of the lid portion.

[0017] In the configuration described above, the pop-up section is located on the outer surface of the lid. When the lid is closed, the pop-up section folds flat against the outer surface of the storage box, approaching the outer surface of the lid. Therefore, a storage box is obtained in which the pop-up section does not take up much space when the lid is closed. For this reason, even if the pop-up section is placed on the outer surface of the storage box, the volume occupied by the storage box does not increase. For example, even when stacking storage boxes with the lids closed, the pop-up section does not get in the way.

[0018] From another perspective, the storage box of the present invention preferably includes the following configuration: The support portion has a sub-pop-up portion connected to the lid portion at a position spaced apart in the thickness direction from one of the sides, and a sub-support portion connecting the lid portion and the sub-pop-up portion. Therefore, it is possible to provide a storage box that improves the degree of freedom in shaping the pop-up portion without compressing the storage space of the storage portion when the lid portion is closed.

[0019] The above configuration allows for the creation of a multi-stage pop-up section. This further improves the design flexibility of the pop-up section.

[0020] From another perspective, the storage box of the present invention preferably includes the following configuration: having a plurality of sets of the pop-up sections and the support sections. The plurality of pop-up sections are arranged in a direction parallel to the pivot axis.

[0021] The above configuration allows for the creation of a parallel-structured pop-up section. This further improves the design flexibility of the pop-up section.

[0022] From another perspective, the storage box of the present invention preferably includes the following configuration: The pivot axis of the pop-up portion and the pivot axis of the support portion each extend in a direction intersecting the pivot axis of the lid portion.

[0023] In the above configuration, when the lid is opened, the pop-up section and support section are pulled up at an angle relative to the edge plate and lid. This allows for the creation of a variety of unexpected pop-up section designs.

[0024] From another perspective, it is preferable that the storage box of the present invention includes the following configuration. The lid portion includes a first plate portion connected to the edge plate of the one side portion to which the lid portion is connected, and a second plate portion that is folded back and connected at the tip of the first plate portion and overlaps the inner surface of the lid portion with respect to the first plate portion. The support portion is connected to the second plate located on the inner surface side of the lid portion.

[0025] In the above configuration, the pop-up portion and the lid portion are integrally formed. Further, at the tip of the lid portion, since the first plate portion and the second plate portion are folded back, the tip of the lid portion becomes smooth. Therefore, the finish quality of the lid portion of the storage box is improved.

[0034] <Overall Structure> A storage box 1, an embodiment of the present invention, will be described using Figures 1 to 6. Figure 1 is a perspective view of the storage box 1 in the embodiment of the present invention with the lid 20 open. Figure 2 is a cross-sectional view taken along the line II-II in Figure 1. Figure 3 is a perspective view of the storage box 1 in the embodiment of the present invention with the lid 20 in the process of being opened or closed. Figure 4 is a cross-sectional view taken along the line IV-IV in Figure 3. Figure 5 is a perspective view of the storage box 1 in the embodiment of the present invention with the lid 20 closed. Figure 6 is a cross-sectional view taken along the line VI-VI in Figure 5.

[0035] As shown in Figures 1 to 6, the storage box 1 is a decorative box formed by folding a single sheet of material. For example, paper can be used as the sheet material. However, the storage box 1 may also be formed by folding a sheet of material other than paper. For example, the storage box 1 may be made of a resin sheet or corrugated cardboard. As shown in Figure 5, when the storage box 1 is closed, it is rectangular in shape when viewed in the depth, width, and height directions.

[0036] The storage box 1 includes a storage section 10, a lid section 20, a pop-up section 30, a support section 40, a sub-pop-up section 60, and a sub-support section 70.

[0037] The storage section 10 has a bottom 11 and a plurality of side sections 121-124. The storage section 10 is located at the lower end of the storage box 1 in the height direction.

[0038] Multiple side sections 121-124 are provided to surround the bottom section 11 on all four sides. Specifically, side section 121 is connected to the front end of the bottom section 11 and extends upward from the bottom section 11. Side section 121 constitutes the front of the storage section 10. Side section 122 is connected to the right end of the bottom section 11 and extends upward from the bottom section 11. Side section 122 constitutes the right side of the storage section 10. Side section 123 is connected to the rear end of the bottom section 11 and extends upward from the bottom section 11. Side section 123 constitutes the rear of the storage section 10. Side section 124 is connected to the left end of the bottom section 11 and extends upward from the bottom section 11. Side section 124 constitutes the left side of the storage section 10. The bottom section 11 and the multiple side sections 121-124 form an upwardly opening opening OP1.

[0039] Each of the multiple side sections 121-124 includes an outer plate 1201, an inner plate 1202, and an edge plate 1203.

[0040] The outer plate 1201 forms the outer surface of the storage section 10. The inner plate 1202 forms the inner surface of the storage section 10 at a predetermined distance from the outer plate 1201. The edge plate 1203 forms the upper surface of the storage section 10. The edge plate 1203 is connected to the upper end of the outer plate 1201 and the upper end of the inner plate 1202. The edge plate 1203 extends from the upper end of the outer plate 1201 to the upper end of the inner plate 1202.

[0041] The lid portion 20 is connected to the storage portion 10 in a way that allows it to be opened and closed. More specifically, the base end portion 21 of the lid portion 20 is connected to the rear end portion of the edge plate 1203 of one of the multiple side portions 121-124, which is the edge plate 1203 of one side portion 123, and is connected to the upper end portion of the outer plate 1201.

[0042] As shown in Figures 2, 4, and 6, the lid portion 20 has a two-layer structure composed of a first plate portion 201 and a second plate portion 202. The first plate portion 201 and the second plate portion 202 overlap in the thickness direction of the lid portion 20. The base end portion 21 of the first plate portion 201 is connected to the edge plate 1203 of one side portion 123 to which the lid portion 20 is connected. The tip portion of the second plate portion 202 is folded back and connected to the tip portion of the first plate portion 201. The second plate portion 202 is located on the inner surface of the lid portion 20 relative to the first plate portion 201. Furthermore, the support portion 40, which will be described later, is connected to the second plate portion 202 located on the inner surface side of the lid portion 20.

[0043] As shown in Figures 1-4, the lid 20 rotates in the closing direction CL relative to one of the side portions 123, using the connection point with the side portion 123 as a pivot axis P20, from an open state where the lid 20 does not cover the opening OP1, to close the opening OP1. The pivot axis P20 is an axis along the base end portion 21.

[0044] Furthermore, as shown in Figure 6, the lid portion 20 rotates in the opening direction OP relative to one side portion 123, from a closed state where the lid portion 20 covering the opening OP1 is closed, to open the opening OP1, with the axis along the base end portion 21 being the pivot axis P20.

[0045] The pop-up section 30 is a plate-shaped part that is decorated by printing or by attaching decorative parts. The base end 31 of the pop-up section 30 is connected to the front end of the edge plate 1203 of one side section 123 to which the lid section 20 is connected, and is located away from the lid section 20 in the thickness direction of one side section 123. That is, the pop-up section 30 is connected to the front end of the edge plate 1203 of one side section 123 and to the upper end of the inner plate 1202. As shown in Figures 1-4 and 6, the pop-up section 30 is configured to be rotatable relative to one side section 123 with the connection part with the edge plate 1203 as a pivot axis P30. The pivot axis P30 is an axis along the base end 31.

[0046] The support portion 40 supports the pop-up portion 30 relative to the lid portion 20. The base end portion 41 of the support portion 40 is connected to the lid portion 20. The tip portion 42 of the support portion 40 is connected to the tip portion 32 of the pop-up portion 30.

[0047] As shown in Figures 1, 2, 4, and 6, the support portion 40 is configured to be rotatable relative to the lid portion 20, with the connection portion to the lid portion 20 being a pivot axis P41. The pivot axis P41 is an axis along the base portion 41. The support portion 40 is also configured to be rotatable relative to the pop-up portion 30, with the connection portion to the pop-up portion 30 being a pivot axis P42. The pivot axis P42 is an axis along the tip portion 42.

[0048] The support portion 40 supports the pop-up portion 30 so that it is parallel to the lid portion 20. The support portion 40 is also connected to the tip portion 32 so that it is parallel to the edge plate 1203. Thus, in the storage box 1, the lid portion 20, the edge plate 1203, the pop-up portion 30, and the support portion 40 constitute the parallel link mechanism LK1 (see Figures 2, 4, and 6 in particular).

[0049] The sub-pop-up section 60 is a plate-shaped part that is decorated by printing or attaching decorative parts. The base end 61 of the sub-pop-up section 60 is connected to the support section 40 at a position separated from the lid section 20 in the thickness direction of one side section 123. As shown in Figures 1, 2, 4, and 6, the sub-pop-up section 60 is configured to be rotatable relative to the support section 40, with the connection point to the support section 40 being a pivot axis P60. The pivot axis P60 is an axis along the base end 61.

[0050] The sub-support portion 70 supports the sub-pop-up portion 60 relative to the lid portion 20. The base end portion 71 of the sub-support portion 70 is connected to the lid portion 20. The tip portion 72 of the sub-support portion 70 is connected to the tip portion 62 of the sub-pop-up portion 60.

[0051] As shown in Figures 1, 2, 4, and 6, the sub-support portion 70 is configured to be rotatable relative to the lid portion 20, with the connection portion to the lid portion 20 being a pivot axis P71. The pivot axis P71 is an axis along the base portion 71. The sub-support portion 70 is also configured to be rotatable relative to the sub-pop-up portion 60, with the connection portion to the sub-pop-up portion 60 being a pivot axis P72. The pivot axis P72 is an axis along the tip portion 72.

[0052] The sub-support portion 70 supports the sub-pop-up portion 60 so that it is parallel to the lid portion 20. The sub-support portion 70 is also connected to the tip portion 72 so that it is parallel to the support portion 40. Thus, in the storage box 1, the lid portion 20, the support portion 40, the sub-pop-up portion 60, and the sub-support portion 70 constitute the parallel link mechanism LK2 (see Figures 2, 4, and 6 in particular).

[0053] Furthermore, as shown in Figure 2, when the lid 20 is open, the raised dimension D1 of the support 40, which is the distance between the lid 20 and the pop-up section 30, is greater than the raised dimension D2 of the sub-support 70, which is the distance between the lid 20 and the sub-pop-up section 60. Also, the raised dimension D1 of the support 40 is the same as the depth dimension D1203 of the edge plate 1203 of the rear side 123.

[0054] <Blank storage box> In addition to Figures 1-6, Figure 7 will be used to explain the blank BL1 used in assembling the storage box 1. Figure 7 is a plan view of the blank BL1 for forming the storage box 1.

[0055] As shown in Figure 7, the blank BL1 of the storage box 1 is a sheet material formed, for example, by punching out the outer edge shape of cardboard and folding it. In Figure 7, mountain folds are indicated by dashed lines, and valley folds are indicated by dotted lines.

[0056] Blank BL1 has a storage compartment forming portion BL10, a lid forming portion BL20, and a rear inner plate forming portion BL30.

[0057] From one end of the blank BL1 along its length to the other, the storage compartment forming section BL10, the lid forming section BL20, and the rear inner panel forming section BL30 are connected in order. The depth, width, and height of the storage compartment 10 can be adjusted by adjusting the dimensions of the storage compartment forming section BL10. The depth of the lid 20 can be adjusted by adjusting the length of the lid forming section BL20. The height and width of the inner panel 1202 of the rear side section 123 can be adjusted by adjusting the length and width of the rear inner panel forming section BL30.

[0058] The storage compartment forming portion BL10 includes a bottom forming portion BL110, a front side forming portion BL11, a right side forming portion BL12, a rear side forming portion BL13, and a left side forming portion BL14.

[0059] The lid forming portion BL20 includes a first plate forming portion BL201, a second plate forming portion BL202, an edge plate forming portion BL203, a pop-up portion forming portion BL230, a support portion forming portion BL240, a sub-pop-up portion forming portion BL260, and a sub-support portion forming portion BL270.

[0060] The size of the pop-up section 30 can be adjusted by adjusting the length and width of the pop-up section forming section BL230. The raised dimension of the pop-up section 30 can be adjusted by adjusting the length of the support section forming section BL240. The size of the sub-pop-up section 30 can be adjusted by adjusting the length and width of the sub-pop-up section forming section BL260. The raised dimension of the sub-pop-up section 30 can be adjusted by adjusting the length of the sub-support section forming section BL270.

[0061] The pop-up section forming section BL230, the support section forming section BL240, the sub-pop-up section forming section BL260, and the sub-support section forming section BL270 are located inward in the width direction of the second plate section forming section BL202.

[0062] At both ends in the width direction of the pop-up section forming part BL230 and the support section forming part BL240, cuts extending in the length direction are formed with the same width. Similarly, at both ends in the width direction of the sub-pop-up section forming part BL260 and the sub-support section forming part BL270, cuts extending in the length direction are formed with the same width.

[0063] Furthermore, the longitudinal dimension DBL240 of the support forming section BL240 is larger than the longitudinal dimension DBL270 of the sub-support forming section BL270. The longitudinal dimension DBL240 of the support forming section BL240 is the same as the longitudinal dimension DBL203 of the edge plate forming section BL203. By adjusting the longitudinal dimension DBL240 of the support forming section BL240 and the longitudinal dimension DBL270 of the sub-support forming section BL270, the upright dimension D1 of the support section 40 and the upright dimension D2 of the sub-support section 70 can be adjusted.

[0064] <Storage box assembly process> An example of the assembly process for the storage box 1 will be explained using Figures 8 to 10. Figure 8 is a perspective view showing the first step S1 of the assembly process, in which the storage box 1 is made by folding the blank BL1. Figure 7 is a perspective view showing the second step S2 of the assembly process, in which the storage box 1 is made by folding the blank BL1. Figure 7 is a perspective view showing the third step S3 of the assembly process, in which the storage box 1 is made by folding the blank BL1.

[0065] In the assembly process of storage box 1, first, in the first step S1 shown in Figure 8, the right side forming part BL12 and the left side forming part BL14 are raised from the bottom forming part BL110 of the blank BL1. In addition, the lid forming part BL20 is raised from the storage part forming part BL10.

[0066] Next, in the second step S2 shown in Figure 9, the raised right-side forming section BL12 and the left-side forming section BL14 are connected to each other by their respective connecting pieces BL121 and BL141. The front-side forming section BL11 and the rear-side forming section BL13 are raised relative to the bottom forming section BL110. In the lid forming section BL20, the second plate forming section BL202 is bent relative to the first plate forming section BL201. With the second plate forming section BL202 superimposed on the inner surface of the first plate forming section BL201, the first plate forming section BL201 and the second plate forming section BL202 are bonded together at the adhesive margin position indicated by the shaded area.

[0067] Next, in the third step S3 shown in Figure 10, the pop-up section forming section BL230, the support section forming section BL240, the sub-pop-up section forming section BL260, and the sub-support section forming section BL270 are raised from the second plate section forming section BL202 along the cut. In addition, the rear inner plate forming section BL30 is positioned to cover the connecting pieces BL121 and BL141.

[0068] Through the above steps, the parallel link mechanisms LK1 and LK2 described above are formed, and the assembly of the storage box 1 as shown in Figures 1 and 2 is completed.

[0069] As described above, in the storage box 1, the parallel link mechanism LK1 is composed of the lid 20, the edge plate 1203, the pop-up section 30, and the support section 40.

[0070] As described above, the storage box 1 consists of a storage section 10 having thick side sections 121, 122, 123, and 124, and a lid section 20. The lid section 20 has a pop-up section 30 which is part of a lifting mechanism that utilizes the thickness of the side section 123 that constitutes the back surface. The lid section 20 and the pop-up section 30 are connected to an edge plate 1203 that connects the upper end of the inner plate 1202 and the upper end of the outer plate 1201 of the side section 123. In other words, the pop-up section 30 is located between the lid section 20 and the inner plate 1202 of the side section 123. Furthermore, a parallel link mechanism LK1, which is a lifting mechanism, is formed by the lid section 20, the edge plate 1203, the pop-up section 30, and the support section 40. The pop-up section 30, which is part of the parallel link mechanism LK1, is configured such that the angle of the lid section 20 relative to the edge plate 1203 is equal to the angle of the pop-up section 30 relative to the edge plate 1203. Therefore, when the lid 20 is closed, the pop-up section 30 folds flat so as to be closer to the inner surface of the lid 20.

[0071] In this design, when the lid 20 is opened, the pop-up section 30 can secure a raised height equal to the gap between the lid 20 and the edge plate 1203 within the width range of the edge plate 1203 in the front-to-back direction. Furthermore, the raised height of the pop-up section 30 can be adjusted by changing the position of the support section 40 within the width range of the edge plate 1203 in the front-to-back direction. This improves the design freedom of the pop-up section 30. Therefore, three-dimensional decoration becomes possible with the pop-up section 30.

[0072] Furthermore, the parallel link mechanism LK1 of the pop-up section 30 is integrally formed by the lid section 20, the edge plate 1203, the pop-up section 30, and the support section 40. Similarly, the parallel link mechanism LK2 is integrally formed by the lid section 20, the edge plate 1203, the sub-pop-up section 60, and the sub-support section 70. In other words, the lid section 20 and the edge plate 1203 also serve as parts of the parallel link mechanisms LK1 and LK2. Because the side sections 123 that constitute the storage section 10 are made thicker, space for arranging the parallel link mechanisms LK1 and LK2 is secured, and the overlapping area of ​​structural members can be reduced. Furthermore, by having the lid section 20 and the edge plate 1203 serve as parts of the parallel link mechanisms LK1 and LK2, space and resources can be saved.

[0073] Furthermore, in the storage box 1, the lid 20 is connected to the edge plate 1203 of one side portion 123 to which the lid 20 is attached, at the connection point between the edge plate 1203 and the outer plate 1201. The pop-up section 30 is connected to a position closer to the inner plate 1202 than to the lid 20. The support section 40 is connected to the inner surface of the lid 20. In other words, the base end 31 of the pop-up section 30 is connected to a position closer to the inner plate 1202 than to the connection point to which the lid 20 is attached. The base end 41 of the support section 40 is connected to the inner surface of the lid 20.

[0074] In the above configuration, the pop-up section 30 is located on the inner surface of the lid section 20. Therefore, when the lid section 20 is closed, the pop-up section 30 folds planarly between the lid section 20 and the storage section 10, as shown in Figure 6, so as to approach the inner surface of the lid section 20. Thus, a storage box 1 can be provided that allows for greater freedom in the design of the pop-up section 30 without compromising the storage space of the storage section 10 when the lid section 20 is closed.

[0075] Furthermore, the storage box 1 has a two-tiered structure consisting of a pop-up section 30 and a sub-pop-up section 60. With the above configuration, a multi-tiered pop-up section 30 can be realized. This further improves the freedom of design for the pop-up section 30.

[0076] In the storage box 1, the lid 20 has a two-layer structure composed of a first plate portion 201 and a second plate portion 202. In the above configuration, the pop-up portion 30 and the lid 20 are integrally formed. Furthermore, since the first plate portion 201 and the second plate portion 202 are folded back at the tip of the lid 20, the tip of the lid 20 becomes smooth. Therefore, the finish quality of the lid 20 of the storage box 1 is improved.

[0077] <Example 1> Using Figure 11, a modified example 1 of the storage box 1 according to the above embodiment will be described. Figure 11 is a perspective view showing the storage box 101 according to modified example 1. The storage box 101 differs from the storage box 1 according to the above embodiment in that it has a plurality of pop-up sections 301, 302, and 303. In the following, components similar to those in the above embodiment will be denoted by the same reference numerals and their descriptions will be omitted, and only components that differ from the above embodiment will be described.

[0078] As shown in Figure 11, the storage box 101 has a storage section 10, a lid section 20, a plurality of pop-up sections 301, 302, 303, and a plurality of support sections 401, 402, 403.

[0079] The base end 41 of the support part 401 is connected to the lid part 20. The tip 42 of the support part 401 is connected to the tip 32 of the pop-up part 301. The base end 41 of the support part 402 is connected to the lid part 20. The tip 42 of the support part 402 is connected to the tip 32 of the pop-up part 302. The base end 41 of the support part 403 is connected to the lid part 20. The tip 42 of the support part 403 is connected to the tip 32 of the pop-up part 303.

[0080] The sets of pop-up section 301 and support section 401, pop-up section 302 and support section 402, and pop-up section 303 and support section 403 are arranged sequentially from right to left in the width direction, which is parallel to the pivot axis P20 of the lid section 20. The dimensions in the width direction of each of the multiple pop-up sections 301, 302, and 303 decrease as they move upward in the height direction. This creates the impression that the multiple pop-up sections 301, 302, and 303 are modeled after spotlights spreading downwards.

[0081] The above configuration allows for the realization of multiple pop-up sections 301, 302, and 303 in a parallel structure. This further improves the design flexibility of the pop-up sections 301, 302, and 303.

[0082] The lifting dimensions of the multiple support parts 401, 402, and 403 are different from each other. This allows for the creation of a sense of depth.

[0083] <Modification 2> Using Figure 12, a modified example 2 of the storage box 1 according to the above embodiment will be described. Figure 12 is a perspective view showing the storage box 102 according to the modified example 2. The storage box 102 differs from the storage box 1 according to the above embodiment in that it has an oblique parallel link mechanism LK21. In the following, components similar to those in the above embodiment will be denoted by the same reference numerals and their descriptions will be omitted, and only components that differ from the above embodiment will be described.

[0084] As shown in Figure 12, the storage box 102 has a storage section 10, a lid section 20, pop-up sections 305 and 306, and support sections 405 and 406.

[0085] The pop-up section 305 is configured to be rotatable relative to one side section 123, with the axis along the base end 31 serving as the pivot axis P305.

[0086] The base end 41 of the support portion 405 is connected to the lid portion 20. The tip end 42 of the support portion 405 is connected to the tip end 32 of the pop-up portion 305. The support portion 405 is configured to be rotatable relative to the lid portion 20, with the axis along the base end 41 being the pivot axis P4051. The support portion 405 is also configured to be rotatable relative to the pop-up portion 305, with the axis along the tip end 42 being the pivot axis P4052.

[0087] The pop-up section 305 and the support section 405 are trapezoidal when viewed in the thickness direction. The pivot axis P305 of the pop-up section 305 and the pivot axis P4051 of the support section 405 each extend in a direction intersecting the pivot axis P20 of the lid section 20. The lid section 20, the edge plate 1203, the pop-up section 305, and the support section 405 constitute the parallel link mechanism LK21.

[0088] The pop-up section 306 and the support section 406 are rectangular in shape when viewed in the thickness direction. The lid section 20, the edge plate 1203, the pop-up section 306, and the support section 406 constitute the parallel link mechanism LK22. The configuration of the parallel link mechanism LK22 is the same as that of the parallel link mechanism LK1 described above, so a detailed explanation will not be repeated here.

[0089] In the above configuration, when the lid 20 is opened, the pop-up section 305 and the support section 405 are pulled up diagonally relative to the edge plate 1203 and the lid 20. This makes it possible to create a variety of unexpected pop-up sections 305.

[0090] Furthermore, the combination of pop-up section 305 and pop-up section 306 can create the impression of a boot motif.

[0091] <Variation 3> A third modification of the storage box 1 according to the above embodiment will be described using Figure 13. Figure 13 is a perspective view showing the storage box 103 according to the third modification. Note that Figure 13 shows the storage box 103 as viewed from the rear. The storage box 103 differs from the storage box 1 according to the above embodiment in that it has a pop-up portion 307 on the outer surface of the lid portion 207. In the following, components similar to those in the above embodiment will be denoted by the same reference numerals and their descriptions will be omitted, and only components that differ from the above embodiment will be described.

[0092] As shown in Figure 13, the storage box 103 includes a storage section 10, a lid section 207, a pop-up section 307, a support section 407, a sub-pop-up section 607, and a sub-support section 707.

[0093] The lid portion 207 is connected to the connection portion on the inner plate 1202 side of the edge plate 1203 of one side portion 123 to which the lid portion 207 is connected. The pop-up portion 30 is connected to a position closer to the outer plate 1201 than the lid portion 20. The support portion 40 is connected to the outer surface of the lid portion 20. In other words, the base end portion 31 of the pop-up portion 307 is connected to a position closer to the outer plate 1201 than the connection portion to which the lid portion 207 is connected.

[0094] The base end 41 of the support portion 407 is connected to the outer surface of the lid portion 207. The tip 42 of the support portion 407 is connected to the tip 32 of the pop-up portion 307.

[0095] The base end 61 of the sub-pop-up section 607 is connected to the support section 407. The base end 71 of the sub-support section 707 is connected to the outer surface of the cover section 207. The tip 72 of the sub-pop-up section 607 is connected to the tip 62 of the sub-pop-up section 707.

[0096] In the storage box 103, the parallel link mechanism LK31 is composed of the lid 207, the edge plate 1203, the pop-up section 307, and the support section 407. In addition, in the storage box 103, the parallel link mechanism LK32 is composed of the lid 207, the support section 407, the sub-pop-up section 607, and the sub-support section 707. The configuration of the parallel link mechanisms LK31 and LK32 is the same as that of the parallel link mechanisms LK1 and LK2 described above, so a detailed explanation will not be repeated here.

[0097] In the above configuration, the pop-up section 307 and the sub-pop-up section 607 are located on the outer surface of the lid 207. When the lid 207 is closed, the pop-up section 307 and the sub-pop-up section 607 fold planarly on the outer surface of the storage box 103 so as to approach the outer surface of the lid 207. Therefore, a storage box 103 is obtained in which the pop-up section 307 and the sub-pop-up section 607 do not take up much space when the lid 207 is closed. For this reason, even if the pop-up section 307 is placed on the outer surface of the storage box 103, the volume occupied by the storage box 103 does not increase. For example, even when stacking storage boxes 103 with the lids 207 closed, the pop-up section 307 and the sub-pop-up section 607 do not get in the way.

[0098] [Other embodiments] In the above-described embodiments and modifications 1-3 (hereinafter referred to as "embodiments, etc."), the storage section 10 has four sides 121-124. When closed, the storage box 1 is rectangular in shape when viewed in the depth, width, and height directions. However, the number of sides may be three or five or more. The storage box may also be polygonal when viewed in the height direction.

[0099] In the embodiments described above, the lid portions 20 and 207 have a two-layer structure composed of a first plate portion 201 and a second plate portion 202. However, the lid portion may also have a single-phase structure composed of a single sheet material.

[0100] In the embodiments described above, the pop-up sections 30, 301, 302, 305, 306, and 307 are plate-shaped members that are decorated by printing or attaching decorative parts. However, the support section may also be decorated. Furthermore, the pop-up section may be decorated by its shape. For example, the pop-up section can be formed into the shape of letters, symbols, or any motif. Also, the sub-support section may be decorated.

[0101] In the embodiments described above, the first plate portion 201 and the second plate portion 202 of the lid portions 20 and 207 are bonded together. However, the first plate portion and the second plate portion of the lid portion do not necessarily have to be bonded together.

[0102] In the above-described embodiment and modification 3, the storage box 1 has a two-stage structure consisting of pop-up sections 30, 307 and sub-pop-up sections 60, 607. However, the storage box may have a three-stage structure with a third sub-pop-up section. The storage box may have a structure with four or more stages. The storage box may have multiple sub-pop-up sections. The storage box may not have sub-pop-up sections.

[0103] In the above-described embodiment, one example of the assembly process for the storage box 1 involves performing the first step S1, the second step S2, and the third step S3 in order. However, the assembly process for the storage box is not limited to this order. The assembly process for the storage box can be appropriately modified depending on the manufacturing equipment for the storage box.

[0104] Although embodiments of the present invention have been described above, the embodiments described above are merely examples for carrying out the present invention. Therefore, the invention is not limited to the embodiments described above, and it is possible to carry out the invention by appropriately modifying the embodiments described above without departing from the spirit of the invention.
