Description

Technical Field

[0001] The present invention relates to an assembly packaging structure of packages and a spacer.

Background Art

[0002] Patent Document 1 describes a hanging package as a packaging container, and FIG. 7 shows a state in which a plurality of hanging packages are assembled and packaged.

[0003] The hanging package is frequently used for packaging small electrical products such as earphones, and has a box portion for packaging the product body and a hanging portion protruding upward in a flap shape from the upper surface of the box portion. In the hanging portion, a hole through which a rod-shaped hook provided to extend substantially horizontally on a product display shelf in a store passes, or a hook hanging portion for hooking on the hook is formed.

[0004] In FIG. 7 of Patent Document 1, when a plurality of hanging packages are aligned and assembled and packaged inside a packaging box (hereinafter, master carton), it is shown that a space at a height corresponding to the hanging portion becomes a dead space inside the master carton. This applies not only to packages having a hanging portion for hanging on a hook in the master carton, but also to packages having a box portion and an extending portion (including the hanging portion) extending upward from the upper surface of the box portion.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The collective packaging structure shown in Patent Document 1 may cause the upper flap of the master carton to deform inward or to collapse locally when force is applied to the master carton from above. If the top flap of the master carton deforms inward or collapses locally, the suspension part of the hanging package may be pushed downward by the top flap, potentially causing deformation or damage. The hanging portion is an important part of the product packaging's appearance, and deformation or damage to this portion can lead to a significant decrease in the product's value. Therefore, a composite packaging structure that houses multiple suspended packages internally is desirable, one that minimizes the impact on the suspension parts of the internal suspended packages even when a downward force is applied to the upper flap of the master carton.

[0007] Therefore, the problem that the present invention aims to solve is to provide a package assembly structure and spacer that makes it difficult for external forces to affect the extension portion that extends to the top of the assembled package. [Means for solving the problem]

[0008] To solve the above problems, the present invention has the following configurations 1) and 2). 1) A package having a box portion and an extension portion extending upward from the upper surface of the box portion, A master carton capable of arranging and accommodating multiple of the aforementioned packages, A spacer placed on top of the multiple packages contained in the master carton, It consists of, When the package is placed in the master carton, a gap is formed between the extended portions of adjacent packages. The spacer has a flat plate portion and a three-dimensional portion that protrudes perpendicularly from the surface of the flat plate portion, having a width smaller than the width of the gap and a height greater than the height of the protruding portion, and is placed so that the three-dimensional portion enters the gap and abuts against the upper surface of the box portion. This is a collective packaging structure for the package. 2) Formed from a foldable rectangular flat plate member, A first three-dimensional portion is formed on one edge of the flat plate member, including three mountain fold lines formed parallel to the edge, A second three-dimensional portion is formed in the middle of the flat plate member, parallel to the first edge, and includes two mountain fold lines and two valley fold lines formed between the two mountain fold lines, The other edge facing the aforementioned edge has a third three-dimensional portion which includes three mountain fold lines formed parallel to the aforementioned edge, The first three-dimensional part and the third three-dimensional part can be formed into a rectangular cross-sectional shape by folding the three mountain fold lines, The second three-dimensional portion is a spacer whose cross-sectional shape can be formed as a triangle by folding the two mountain fold lines and the two valley fold lines. [Effects of the Invention]

[0009] According to one aspect of the present invention, the effect is obtained that the extension portion extending to the upper part of the bundled package is less susceptible to the influence of external forces. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0011] The collective packaging structure and spacer of the package according to the embodiment of the present invention will be described by the collective packaging structure PK and spacer 5 of the example. The package according to the embodiment of the present invention has a box portion for accommodating a product and an extension portion extending upward from the upper surface of the box portion. As an example of the package, a hanging type package having a hanging portion for hooking on a hook provided on a product display shelf will be described.

[0012] First, the hanging type package 1 packaged by the collective packaging structure PK will be described with reference to FIGS. 1A to 1C. FIG. 1A is a front view of the hanging type package 1, FIG. 1B is a side view of the hanging type package 1, and FIG. 1C is a top view of the hanging type package 1. The up-down, front-back, left-right directions in the figure are directions set for convenience of explanation and correspond to the respective directions set in the collective packaging structure PK described later.

[0013] The hanging type package 1 has a box portion 11 for packaging and accommodating a product, and a hanging portion 12 which is an extension portion extending upward at the center position in the front-back direction of the upper surface 11a of the box portion. The box portion 11 accommodates, for example, earphones as a product inside. The box portion 11 is formed in a rectangular parallelepiped shape determined by, for example, the width W11 in the left-right direction, the depth D11 in the front-back direction, and the height H11 in the up-down direction.

[0014] The suspension portion 12 is formed in the shape of a thin plate extending in the left-right and up-down directions. Specifically, the suspension portion 12 is formed in the shape of a flap with a width W12 in the left-right direction and a height H12 and thickness t12 in the up-down direction. The suspension portion 12 has a suspension hole 12a in the central part, which is a through hole through which a hook of the display shelf is inserted.

[0015] The suspension section 12 is located in the center of the upper surface 11a of the box section 11 in both the left-right and front-back directions. The width W12 of the suspension section 12 is set to be narrower (smaller) than the width W11 of the box section 11, for example, about half. Examples of each dimension are approximate. W11:93mm, D11:47mm, H11:140mm, W12:43mm H12: 25mm, t12: 2mm That is the case.

[0016] Next, a collective packaging structure PK, which bundles multiple of the aforementioned hanging type packages 1 together, will be explained with reference to Figure 2, which is an exploded view. As shown in Figure 2, the collective packaging structure PK packages a total of 20 hanging packages 1 in four rows horizontally and five rows vertically.

[0017] The collective packaging structure PK consists of a master carton 2, a base plate 3, a package group 1G which is a group of 20 suspended packages 1, and spacers 5. Master carton 2 is, for example, a corrugated cardboard box of type A, and has a body 2M, a lower flap group 2B, and an upper flap group 2T.

[0018] The body section 2M is frame-shaped, with the front panel 21, right panel 23, rear panel 24, and left panel 22 being connected. The lower flap group 2B includes a left lower inner flap 262 and a right lower inner flap 263 connected to the lower edges of the left panel 22 and the right panel 23, respectively, and a front lower outer flap 261 and a rear lower outer flap 264 connected to the lower edges of the front panel 21 and the rear panel 24, respectively. The upper flap group 2T includes a left upper inner flap 252 and a right upper inner flap 253 connected to the upper edges of the left panel 22 and the right panel 23, respectively, and a front upper outer flap 251 and a rear upper outer flap 254 connected to the upper edges of the front panel 21 and the rear panel 24, respectively. Master carton 2 is formed, for example, with the height direction as the flute direction. The flute direction is the direction in which the wavy lines of the corrugated core extend in the corrugated cardboard.

[0019] The base plate 3 is placed on top of the lower flap group 2B in the assembled state of the master carton 2, which is a type A corrugated cardboard box. This eliminates any height differences that may occur due to the combination of the lower flap group 2B. Multiple hanging packages 1 are placed on the base plate 3 in a predetermined alignment pattern. By placing the base plate 3, multiple hanging packages 1 are placed on the same plane, and the heights of the hanging parts 12 are aligned.

[0020] The spacer 5 is placed on top of a plurality of suspended packages 1 that are arranged in alignment on a base plate 3. The spacer 5 has a first flat plate 51 and a second flat plate 52 as flat plate sections, and a first three-dimensional section 53, a second three-dimensional section 54, and a third three-dimensional section 55 that are formed by bending. In the cross-sectional shape of the spacer 5, the first three-dimensional portion 53 and the third three-dimensional portion 55 are formed as rectangles, and the second three-dimensional portion 54 is formed as a triangle.

[0021] Here, spacer 5 will be described in detail with reference to Figures 3 and 4. Figure 3 is an unfolded view of spacer 5, showing a plan view of the spacer material 5m. Figure 4 is a diagram illustrating the assembly procedure for forming spacer 5 from spacer material 5m.

[0022] In Figure 3, the spacer 5 is formed as a rectangular spacer material 5m that is long from left to right when unfolded. The spacer material 5m is formed in a flat shape from corrugated cardboard, and its flute direction is, for example, left to right. The spacer material 5m is divided into regions that will become the first three-dimensional section 53, the first flat plate 51, the second three-dimensional section 54, the second flat plate 52, and the third three-dimensional section 55, from left to right in Figure 3. Here, for ease of understanding, the regions in the spacer material 5m that will become the first three-dimensional section 53, the first flat plate 51, the second three-dimensional section 54, the second flat plate 52, and the third three-dimensional section 55 of the assembled spacer 5 will be described using the same names. That is, the first three-dimensional section 53 in the spacer material 5m refers to the part that will become the first three-dimensional section 53 in the spacer 5.

[0023] In the spacer material 5m, the first three-dimensional section 53 is further divided into regions that form the first side plate 531, the first bottom plate 532, and the second side plate 533, which extend in the front-rear direction. The boundary between the first side plate 531 and the first bottom plate 532 is a mountain fold line P33, the boundary between the first bottom plate 532 and the second side plate 533 is a mountain fold line P32, and the boundary between the second side plate 533 and the first flat plate 51 is a mountain fold line P31. The mountain fold lines P31 to P33 are formed as multiple parallel fold lines relative to the left edge, which is one edge of the spacer material 5m. A pair of first insertion pieces 534 are formed on the left edge of the first side plate 531, which is the left edge of the spacer material 5m, extending to the left at a distance from each other in the front-rear direction. The first insertion pieces 534 are flattened hexagonal shapes that are crushed in the left-right direction.

[0024] The second three-dimensional section 54 is further divided into regions that form the third side plate 541, the second bottom plate 542, and the fourth side plate 543, which extend in the front-rear direction. A mountain fold line P44 is formed at the boundary between the first flat plate 51 and the third side plate 541. Valley fold lines P43 and P42 are formed at the boundary between the third side plate 541 and the second bottom plate 542, and at the boundary between the second bottom plate 542 and the fourth side plate 543, respectively. A mountain fold line P41 is formed at the boundary between the fourth side plate 543 and the second flat plate 52.

[0025] The third three-dimensional section 55 is further divided into regions that form the fifth side plate 551, the third bottom plate 552, and the sixth side plate 553, which extend in the front-rear direction. A mountain fold line P51 is formed at the boundary between the second flat plate 52 and the fifth side plate 551, a mountain fold line P52 is formed at the boundary between the fifth side plate 551 and the third bottom plate 552, and a mountain fold line P53 is formed at the boundary between the third bottom plate 552 and the sixth side plate 553. On the right edge of the sixth side plate 553, which is the right edge of the spacer material 5m, a pair of third insertion pieces 554 are formed, extending to the right and spaced apart in the front-rear direction. The third insertion pieces 554 are flattened hexagonal shapes that are crushed in the left-right direction.

[0026] The first flat plate 51 has a pair of first insertion holes 513 formed at predetermined positions in the left-right direction and spaced apart in the front-rear direction. The front-rear positions of the pair of first insertion holes 513 correspond to the front-rear positions of the pair of first insertion pieces 534, respectively. In the first three-dimensional section 53, the width W533 of the second side plate 533 is set to be larger than the width W531 of the first side plate 531. Also, the distance L513 in the left-right direction from the mountain fold line P31 to the first insertion hole 513 is set to be smaller than the width W532 of the first bottom plate 532. Furthermore, the width W533 of the second side plate 533 is set to be greater than the height H12 (see Figure 1) of the suspension part 12 of the suspension package 1.

[0027] The width W541 of the third side plate 541 and the width W543 of the fourth side plate 543 in the second three-dimensional section 54 are the same size.

[0028] In the spacer material 5m, the first three-dimensional section 53 and the third three-dimensional section 55 are symmetrical. That is, widths W551, W552, and W553 are the same as widths W533, W532, and W533, respectively.

[0029] The widths W532, W542, and W552 of the first bottom plate 532, the second bottom plate 542, and the third bottom plate 552 are equal to each other. These widths are set to be slightly smaller than the width Ws, which is the difference between the width W11 of the box section 11 and the width W12 of the hanging section 12 in the hanging package 1 shown in Figures 1A and 5. The width Ws is expressed as (width W11 - width W12).

[0030] The second flat plate 52 has a pair of third insertion holes 525 formed at the same position in the left-right direction and spaced apart in the front-rear direction. The front-rear positions of the pair of third insertion holes 525 correspond to the front-rear positions of the pair of third insertion pieces 554, respectively. Similar to the first three-dimensional section 53, in the third three-dimensional section 55, the distance L525 in the left-right direction from the mountain fold line P51 to the third insertion hole 525 is set to be smaller than the width W552 of the third base plate 552. Furthermore, the width W551 of the fifth side panel 551 is set to be larger than the height H12 of the suspension part 12 of the suspension package 1, and is the same size as the second side panel 533 of the first three-dimensional part 53.

[0031] A second insertion piece 544 is formed on the left edge of the second flat plate 52 by cutting in from the mountain fold line P41 to the right. The second insertion pieces 544 are formed in pairs, spaced apart in the front-to-back direction, and have a flattened hexagonal shape that is compressed in the left-to-right direction. On the right edge of the first flat plate 51, a pair of second insertion holes 514 are formed by cutting out to the left from the mountain fold line P44 at positions corresponding to the pair of second insertion pieces 544 in the front-to-back direction.

[0032] The spacer material 5m is formed into a three-dimensional object, spacer 5, by following the procedure shown in Figure 4. In Figure 4, the first three-dimensional part 53 is shown in an assembled state, while the second three-dimensional part 54 and the third three-dimensional part 55 are shown in an incomplete state.

[0033] In Figure 4, the third three-dimensional part 55 is folded along the mountain fold lines P51 to P53, and the third insertion piece 554 is inserted into the third insertion hole 525. The same applies to the first three-dimensional part 53; the mountain fold lines P31 to P33 are folded, and the first insertion piece 534 is inserted into the first insertion hole 513.

[0034] The first insertion piece 534 and the third insertion piece 554 are formed in the shape of a flattened hexagon as described above, and the lengths of the first insertion hole 513 and the third insertion hole 525 are formed to be smaller than the maximum length of the first insertion piece 534 and the third insertion piece 554 in the front-to-back direction, respectively. Therefore, the first insertion piece 534 and the third insertion piece 554 are inserted into the first insertion hole 513 and the third insertion hole 525, respectively, in a forceful fit. As a result, the first insertion piece 534 and the third insertion piece 554, which are inserted through the first insertion hole 513 and the third insertion hole 525, are less likely to come loose, and the three-dimensional shapes of the first three-dimensional part 53 in Figure 4 and the third three-dimensional part 55 shown in Figure 2 are stably maintained.

[0035] In the spacer material 5m, the notch of the second insertion piece 544 of the second three-dimensional part 54 is formed in the opposite direction to the second insertion hole 514 with respect to the mountain fold line P41. Therefore, the second insertion piece 544 is raised from the second flat plate 52 and rotated approximately 180° as shown by arrow DR1 in Figure 4, and then inserted into the second insertion hole 514. The second insertion piece 544 is also formed in a flattened hexagon shape, and the length of the second insertion hole 514 in the front-to-back direction is shorter than the maximum length of the second insertion piece 544 in the front-to-back direction. Therefore, the second insertion piece 544 is inserted into the second insertion hole 514 with a strong fit. As a result, the second insertion piece 544 inserted into the second insertion hole 514 is less likely to come loose.

[0036] In spacer 5, the second insertion piece 544 is inserted into the second insertion hole 514 after being rotated 180° from the initial state of the spacer material 5m. Therefore, a rotational force is generated in the second insertion piece 544 that tries to return it to its original position. In other words, a force is always generated in the second insertion piece 544 inserted into the second insertion hole 514 in a direction different from the direction of removal. As a result, the second insertion piece 544 is less likely to come out of the second insertion hole 514. In this way, the second three-dimensional part 54 stably maintains a three-dimensional shape with a triangular cross-sectional shape as shown in Figures 2 and 5, when the second insertion piece 544 is inserted into the second insertion hole 514.

[0037] Figure 5 is a cross-sectional view at position S5-S5 in Figure 2. As shown in Figure 5, in the spacer 5, the vertical heights between the upper surfaces of the first flat plate 51 and the second flat plate 52 and the first bottom plate 532 of the first three-dimensional section 53, the second bottom plate 542 of the second three-dimensional section 54, and the third bottom plate 552 of the third three-dimensional section 55 are heights H53, H54, and H55, respectively. Heights H53, H54, and H55 are equal to each other, and heights H53 and H55 are approximately equal to the width W533 of the second side plate 533 and the width W551 of the fifth side plate 551. In the spacer material 5m, the widths W541 and W543 of the third side plate 541 and the fourth side plate 543 of the second three-dimensional section 54 are determined so that when assembled into spacer 5, the height H54 is the same as the height H53 of the first three-dimensional section 53 and the height H55 of the third three-dimensional section 55. Therefore, when spacer 5 is assembled from spacer material 5m, the first bottom plate 532 of the first three-dimensional section 53, the second bottom plate 542 of the second three-dimensional section 54, and the third bottom plate 552 of the third three-dimensional section 55 are formed flush with the surface. In other words, the first bottom plate 532, the second bottom plate 542, and the third bottom plate 552 of the spacer 5 are surfaces that face the upper surface 11a of the box portion 11 of the hanging package 1 which is arranged and stored in the master carton 2.

[0038] The packaging state of the collective packaging structure PK of the suspended package 1 using the spacer 5 described above will be explained mainly with reference to Figures 5 to 7. Figure 5 is a cross-sectional view at position S5-S5 in Figure 2, Figure 6 is a cross-sectional view at position S6-S6 in Figure 5, and Figure 7 is a top view showing the collective packaging structure PK in an opened state.

[0039] As shown in Figure 2, in the collective packaging structure PK, the procedure for packaging multiple hanging packages 1 is as follows: First, the lower flap group 2B of the master carton 2 is assembled to form a box shape with the top open, and a base plate 3 is placed at the bottom inside. The hanging packages 1 are placed on the base plate 3, arranged in four rows horizontally and five rows vertically, and then placed inside the master carton 2. The master carton 2 is pre-made with internal dimensions that allow the hanging packages 1 to be placed in four rows horizontally and five rows vertically with almost no gaps.

[0040] The spacer 5 is first formed from a flat spacer material 5m by creating the first three-dimensional section 53 to the third three-dimensional section 55 as described above, and is then placed on top of multiple suspended packages 1 in a position where the first to third three-dimensional sections 53 to 54 extend in the front-to-back direction. In the collective packaging structure PK, the hanging packages 1 are arranged in 4x5 rows inside the master carton 2, resulting in three gaps S between the hanging parts 12 of adjacent hanging packages 1 in the left-right direction. The width of these gaps S in the left-right direction is Ws, as shown in Figure 5. The widths W51 and W52 in the left-right direction of the first flat plate 51 and the second flat plate 52 are determined so that the first three-dimensional part 53, the second three-dimensional part 54, and the third three-dimensional part 55 of the spacer 5 enter into the gaps S at each of the three locations.

[0041] Once the spacer 5 is placed so that the first to third three-dimensional sections 53 to 55 enter the gap S between the adjacent suspension sections 12 in the left-right direction, the upper flap group 2T of the master carton 2 is closed and sealed. In this state, the first to third three-dimensional parts 53 to 55 of the spacer 5 are in contact with and placed on the upper surface 11a of the box part 11 of the hanging package 1. As shown in Figure 5, the widths W53 to W55 of the first to third three-dimensional sections 53 to 55 are largest at the ends furthest from the first flat plate 51 and the second flat plate 52, with the widths at these ends corresponding to widths W532, W542, and 552, respectively. This makes it less likely for the deformed part to come into contact with the suspension part 12 if the cross-sectional shape of any of the first to third three-dimensional parts 53 to 55 is deformed due to an unexpected event, thereby suppressing any impact on the quality of the suspension part 12.

[0042] In the sealed state of the collective packaging structure PK, the upper left inner flap 252 of the upper flap group 2T overlaps the first insertion piece 534 that protrudes upward in the spacer 5. Similarly, the upper right inner flap 253 overlaps the upper part of the third insertion piece 554. In other words, in the sealed state, the first insertion piece 534 and the third insertion piece 554 are in close proximity to or in contact with the upper left inner flap 252 and the upper right inner flap 253 of the master carton 2 in the vertical direction.

[0043] As a result, the spacer 5 has no vertical play and is difficult to move within the master carton 2, and the positions of the multiple suspended packages 1 are stably maintained.

[0044] In the collective packaging structure PK, if an unexpected and excessive force is applied from above to the upper flap group 2T, the first insertion piece 534 and the third insertion piece 554 of the first three-dimensional section 53 and the third three-dimensional section 55, respectively, are pressed downward by the upper left inner flap 252 and the upper right inner flap 253. As a result, the first insertion piece 534 and the third insertion piece 554 do not come out of the first insertion hole 513 and the third insertion hole 525, respectively. In other words, the first three-dimensional section 53 and the third three-dimensional section 55 of the spacer 5 are less likely to be crushed against an upward force, and their three-dimensional shape is maintained without the heights H53 and H55 being substantially reduced.

[0045] This makes the suspension part 12 of the suspended package 1 less susceptible to external forces, preventing problems such as deformation or damage to the suspension part 12 due to external forces.

[0046] The embodiments described in detail above are not limited to their configurations, and modified versions are also possible without departing from the spirit of the present invention.

[0047] The format of Master Carton 2 is not limited to Type A and can be freely selected. In the case of a format without an inner flap on top, the internal height dimension should be set so that the first insertion piece 534 and the third insertion piece 554 of Spacer 5 are close to or in contact with the lid plate which will serve as the outer flap in the vertical direction. The material and flute direction of the spacer 5 and master carton 2 are not limited. They may be selected as appropriate to achieve the required strength.

[0048] The packages to be placed in the master carton 2 are not limited to the hanging type package 1 having a hanging portion 12 as described above, but may also be packages having an extension portion corresponding to the hanging portion 12 above the box portion 11. In Figure 5, when packages having an extension portion corresponding to a suspension portion 12 above the box portion 11 are assembled and packed into a master carton 2, the number of rows in the left-right direction is not limited to four. In the case of three rows, there is one gap S, so the spacer 5 can be modified by removing the second three-dimensional portion 54 and the second flat plate 52, so that two three-dimensional portions are formed on both the left and right edges. On the other hand, in the case of five or more rows, four or more gaps S are formed, and the spacers 5 can be increased by adding second three-dimensional parts 54 and second flat plates 52 with a triangular cross-sectional shape, so that they enter the gaps S between adjacent suspension parts 12. For example, in the case of seven rows, the second three-dimensional parts 54 and second flat plates can be increased to four each. The three-dimensional parts that can be formed on both the left and right edges of the 5m spacer material have a rectangular or triangular cross-sectional shape. The three-dimensional parts other than those on the left and right edges have a triangular cross-sectional shape. Therefore, when gaps S are formed in three or more locations in the width direction of the suspension part 12 in the assembled packaging state, the three-dimensional parts that enter the gaps S other than the outermost one will have a triangular cross-sectional shape. The spacer 5 is not limited to being formed so that the first to third three-dimensional parts 53 to 55 enter the gap S in the width direction (left-right direction) of the adjacent suspension part 12, but may also be formed so as to enter the gap Sa (see Figure 6) in a direction perpendicular to the width direction (front-back direction).
