Description

Technical Field

[0006] , , , , ,

[0001] The present invention relates to a partition board for packaging.

Background Art

[0002] Conventionally, when transporting, displaying, and storing various items such as relatively fragile confectionery and sundries that are individually packaged, a packaging partition board formed of cardboard, corrugated board, etc. has been used. The conventional packaging partition board has, for example, a locking portion that suppresses the movement of the stored items in the front-rear direction, and is used in a state of being housed in a body box.

[0003] The locking portion is provided in a state where sufficient space is secured in the front-rear direction of the body box in order to sufficiently suppress the movement of the stored items in the front-rear direction. However, the space thus secured becomes a so-called dead space where the stored items cannot be stored, and thus the storage efficiency was not good.

[0004] Also, as a related prior art, for example, an assembled partition tool having partition members that partition the space of a storage box in the horizontal and vertical directions respectively has been proposed (Patent Document 1). Further, a packaging partition for holding a packaged item (stored item) in an inclined state in which a plurality of partition pieces provided with cut grooves are arranged side by side in the horizontal direction and the ends thereof are inserted into the cut grooves has been proposed (Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the partition proposed in Patent Document 1 lacks a member for securing stored items, and therefore could not fix the stored items within the storage box. As a result, when subjected to impact from above or below, the stored items were prone to contact with the lid and were easily damaged. Furthermore, since only one item was stored in each compartment, it was not possible to store adjacent items with some overlap, resulting in poor storage efficiency. In addition, to fix the stored items within the storage box to a certain extent, it was necessary to provide partition members that precisely matched the shape and size of the stored items, which resulted in a lack of design flexibility.

[0007] Furthermore, the packaging divider proposed in Patent Document 2 had the problem of relatively low holding force because only the ends of the contents inserted into the groove were held. In addition, it was not possible to store adjacent contents with some overlapping parts, so the storage efficiency could not be said to be good.

[0008] This invention has been made in view of the problems of the prior art, and its objective is to provide a packaging divider plate with a high degree of design flexibility that can stably hold and store contents within a box while suppressing movement of the contents even when subjected to impacts from either the left-right (lateral) or front-back (vertical) direction.

Embodiments for Carrying out the Invention

[0012] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments. In this specification, the "left - right direction (lateral direction)" and the "front - rear direction (longitudinal direction)" respectively mean the directions indicated by the arrows shown in FIG. 1. The left - right direction and the front - rear direction are orthogonal to each other. Also, in this specification, the "up - down direction" means a direction orthogonal to the above "front - rear direction" and "front - rear direction" respectively. For example, the direction toward the front of the paper in FIG. 2 is the "upward direction", and the direction toward the back of the paper is the "downward direction". In this specification, "vertical", "orthogonal", and "parallel" include the range of errors generally allowed in the field to which the present invention belongs. Specifically, it also includes cases where there is a deviation within a range less than several degrees (for example, 2 - 3°) from strict vertical, orthogonal, and parallel.

[0013] FIG. 1 is a top view showing an embodiment of the packaging partition plate of the present invention, and FIG. 4 is a partial enlarged view of FIG. 1. As shown in FIGS. 1 and 4, the packaging partition plate 10 of this embodiment is a partition plate for holding stored items, which is housed in the body box 12, and includes a ridge portion 14 and a first locking piece 16. The ridge portion 14 is formed by a front inclined surface 18 and a back surface 20, and its top portion 22 is a portion that extends between the left - right direction ends of the packaging partition plate 10. Also, one lateral end (the right end in FIGS. 1 and 4) of the first locking piece 16 is arranged to form a first connecting end 24 connected to the front inclined surface 18. As shown in FIG. 6, this first locking piece 16 is a member that presses and holds the lateral end 28 of the stored item 26 against the ridge portion 14. By providing these ridge portion 14 and first locking piece 16, the movement of the stored item 26 can be suppressed against impacts applied from any of the left - right direction (lateral direction) and the front - rear direction (longitudinal direction).

[0014] The first locking piece 16 is formed by a notch formed in the mount 30. Note that the first locking piece may be a separate member different from the mount 30 provided by being adhered to the mount 30 or the like. And a ruled line 32 for bending the first locking piece 16 at the position of the first connecting end 24 is provided at the first connecting end 24. By providing such a ruled line 32, it is possible to reliably raise the first locking piece 16 starting from the first connecting end 24 and form a space for inserting the stored item 26 formed between the front inclined surface 18 and the first locking piece 16. Note that if it is possible to bend starting from the first connecting end 24 and raise the first locking piece 16, other than the ruled line 32, a broken line, a perforation, or the like may be provided.

[0015] The packaging partition plate 10 further includes a second locking piece 36. The other horizontal end (the left end in FIG. 1) of the second locking piece 36 forms a second connecting end 34 connected to the first locking piece. The second locking piece 36 is preferably formed by a notch formed in the first locking piece 16. Note that the second locking piece may be a separate member different from the first locking piece 16 provided by being adhered to the first locking piece 16 or the like. The second locking piece 36 can move in the left - right direction with respect to the first locking piece 16. Thereby, it is possible to raise the second locking piece 36 starting from the second connecting end 34 and form a space for storing the stored item 26. As a result, as shown in FIG. 6, when the first locking piece 16 is raised to store the stored item 26, a part of the horizontal end 28 of the stored item 26 can be further inserted to the first connecting end 24 which is deeper in the left - right direction, and the stored item 26 can be held more reliably. Note that a ruled line, a broken line, a perforation, or the like for bending the second locking piece 36 at the position of the second connecting end 34 may be provided at the second connecting end 34. By providing such bending lines such as ruled lines and broken lines, it is possible to reliably raise the second locking piece 36 starting from the second connecting end 34.

[0016] The packaging partition plate 10 includes a plurality of first locking pieces 16 arranged in the left - right direction. By arranging the plurality of first locking pieces 16 in the left - right direction, as shown in FIG. 7, it is possible to store a plurality of stored items 26 adjacent to each other in the left - right direction, and the storage efficiency can be improved.

[0017] Furthermore, the packaging divider plate 10 is equipped with a plurality of second locking pieces 36. The other lateral end (left end in Figure 1) of the plurality of second locking pieces 36 forms a second connecting end 34 connected to the first locking piece 16. These second locking pieces 36 are members that press and hold the lateral ends 28 of the stored items 26 held by the first locking piece 16, which are positioned adjacent to the first connecting end 24 of the first locking piece 16, against the forward inclined surface 18. By providing such second locking pieces 36, the lateral ends 28 of the stored items 26 held by the first locking piece 16 can be inserted to the first connecting end 24 in the left-right direction. This further suppresses the movement of the stored items 26 due to impacts applied particularly from the left-right direction, and allows them to be held more stably within the box 12. In addition, by providing the second locking pieces 36, as shown in Figures 7 and 8, the ends of adjacent stored items 26 in the left-right direction can be overlapped for storage. Therefore, it is possible to improve storage efficiency, and since more items can be stored in a narrow box, it can contribute to reducing material costs.

[0018] The packaging divider plate 10 is provided with a plurality of ridges 14 arranged substantially parallel to each other in the front-to-back direction. By arranging such a plurality of ridges substantially parallel to each other in the front-to-back direction, as shown in Figure 8, it becomes possible to store more items 26, further improving storage efficiency in the front-to-back direction. In addition, the packaging divider plate 10 of this embodiment makes it possible to secure space to store items 26 up to the front and rear ends of the box 12, further improving storage efficiency.

[0019] Preferably, the width of at least one of the multiple ridges 14 in the packaging divider plate 10 is approximately the same as the inner width of the box 12. By making the width of at least one ridge 14 approximately the same as the inner width of the box 12, the edge of the ridge 14 will come into contact with the inner wall surface of the box 12. Therefore, even if an impact is applied to the box 12 from the left or right, the entire packaging divider plate 10 can absorb the impact, preventing deformation of individual ridges 14 and protecting the contents 26 from impact.

[0020] Examples of the shapes of the first and second locking pieces include cloud-shaped, semicircular, rectangular, and irregular shapes, respectively. Among these, as shown in Figures 1 and 2, the shapes of the first locking piece 16 and the second locking piece 36 are preferably cloud-shaped. Furthermore, the outer edge of the first locking piece 16 is preferably curved. Because the first locking piece 16 has a curved outer edge, it is easy to grasp with fingers, etc., and can be easily raised (pulled up), making it easy to create a space for inserting the side edge of the stored item 26. Similarly, the outer edge of the second locking piece 36 is preferably curved. Because the second locking piece 36 has a curved outer edge, it is easy to grasp with fingers, etc., and can be easily raised (pulled up), making it easy to create a space for inserting the side edge of the stored item.

[0021] Figure 2 is an explanatory diagram showing one embodiment of the packaging divider plate of the present invention, and is a diagram showing the packaging divider plate 10 shown in Figure 1 in a partially stretched state. As shown in Figure 2, the first locking piece 16 is formed by a notch formed in the cardboard base 30 that spans the front inclined surface 18 and the back surface 20 of the peak portion 14 in the front-rear direction. By forming the first locking piece 16 by a notch formed that spans the front inclined surface 18 and the back surface 20 in this way, it is possible to sufficiently secure the height of the first locking piece 16 to be higher than the peak of the peak portion 14 in the vertical direction, so that even stored items 26 that are higher than the peak of the peak portion 14 can be stored stably, and the stored items 26 can be pressed and held more reliably against the peak portion 14. The degree (depth) of the notch in the back surface 20 can be appropriately adjusted according to the dimensions and shape of the stored items to be stored. For this reason, the packaging divider plate 10 of this embodiment can be easily redesigned according to the dimensions and shape of the stored items, and the degree of design freedom can be increased.

[0022] Furthermore, as shown in Figure 2, the packaging divider plate 10 further includes a base portion 40 that is connected to the base portion 38 of the front inclined surface 18 and abuts against the inner bottom surface of the box 12. By providing the base portion 40, the frictional force generated between the inner bottom surface of the box 12 and the base portion 40 allows the packaging divider plate 10 to be held more stably inside the box 12. The first locking piece 16 is formed by a notch formed in the cardboard backing 30 that spans the front inclined surface 18 of the ridge portion 14 and the base portion 40. By forming the first locking piece 16 by a notch formed that spans the front inclined surface 18 and the base portion 40 in this way, it is possible to create a larger space formed by the first locking piece 16 in the front-to-back direction, allowing the stored items 26 to be pressed and held more securely against the ridge portion 14. The degree (depth) of the notch in the base portion 40 can be appropriately adjusted according to the dimensions and shape of the stored items. Therefore, the packaging divider plate 10 of this embodiment can be easily modified in design according to the dimensions and shape of the contents, and a high degree of design flexibility can be achieved.

[0023] As shown in Figure 2, the packaging divider plate 10 is further equipped with a rear support piece 42 that supports the back of the contents 26, with its upper end protruding above the top 22 of the ridge portion 14. By providing the rear support piece 42 that supports the back of the contents 26, the movement of the contents 26 due to impacts applied particularly from the front and rear directions is further suppressed, and the contents can be held more stably inside the box 12.

[0024] As shown in Figure 2, the ridge portion 14 can be formed by folding the cardboard backing 30 in a mountain fold. Figure 5 is a partially enlarged view showing an example of the state in which the first locking piece is pulled up. As shown in Figure 5, the packaging partition plate 10 further includes an inner bottom contact piece 44 that protrudes to the rear and abuts against the inner bottom surface of the box 12, formed by a notch formed in the front inclined surface 18 of the ridge portion 14. The inner bottom contact piece 44 is formed to protrude to the rear with respect to the valley fold line 56 formed between the lower end of the front inclined surface 18 and the base portion 40. By providing such an inner bottom contact piece 44, the frictional force generated between the inner bottom surface of the box 12 and the inner bottom contact piece 44 maintains the shape of the ridge portion 14 and allows the packaging partition plate 10 to be held more stably inside the box 12.

[0025] As shown in Figure 2, the packaging divider plate 10 has insertion portions 46 and 48 (lateral insertion portions) that protrude laterally from the areas where the peak portion 14 and base portion 40 are formed and are inserted into the inner wall of the box 12. In addition, the packaging divider plate 10 has an insertion portion 50 (front insertion portion) at its end that protrudes forward and is inserted into the inner wall of the box 12. By providing these insertion portions, the packaging divider plate 10 can be fixed inside the box 12. As a result, the packaging divider plate 10 is less likely to shift position inside the box 12 due to impacts applied from any direction, front-to-back or left-to-right, further suppressing damage to the contents.

[0026] The insertion section 46 is formed by overlapping the backing paper 30. Alternatively, the insertion section 46 is formed from a single backing paper 30, rather than by overlapping the backing paper 30. The insertion section 46 formed by overlapping the backing paper has improved strength, so even if the box 12 is subjected to impact, the insertion section 46 itself is less likely to be damaged, and the displacement of the packaging divider plate 10 inside the box 12 can be further suppressed.

[0027] The packaging divider of the present invention can be formed from materials such as paper, plastic (resin), and corrugated plastic. It can also be formed by combining multiple materials. Among these, it is preferable to form it from paper because it allows for improved pressing force from the first and second locking pieces. Examples of paper materials include cardboard and corrugated cardboard. Furthermore, it may be formed by combining multiple paper materials.

[0028] Figure 3 is an unfolded view showing one embodiment of the packaging divider of the present invention. To manufacture the packaging divider, first, a blank 60 is made by providing cuts 52, mountain fold lines 54 and valley fold lines 56 in a base 30 made of paper or the like, and shaping the outer edge 58 so that insertion parts 46, 48, and 50 are formed. The mountain fold lines 54 and valley fold lines 56 can be formed, for example, by creases for folding, perforations, and dashed lines. Next, the mountain fold lines 54 and valley fold lines 56 of the manufactured blank 60 are folded, respectively, and the first locking piece 16 and the second locking piece 36 are pulled up appropriately to obtain the packaging divider 10 of the embodiment shown in Figures 1 and 2.

[0029] As described above, when manufacturing the packaging divider plate 10 of this embodiment using a single sheet of cardboard or other flat material, the size (depth) of the cuts for forming the first locking piece 16 and the second locking piece 36 can be set to appropriately accommodate the dimensions of the stored items and hold them stably. Furthermore, the dimensions of the stored items can also be appropriately accommodated by reducing or increasing the spacing between the multiple ridges 14 which are arranged substantially parallel to each other. In other words, the packaging divider plate 10 of this embodiment can easily accommodate changes in the dimensions of the stored items without significant design changes, and is highly versatile.

[0030] To store items in the packaging divider plate 10 of this embodiment, as shown in Figure 6, first, the item 26 is inserted between the forward inclined surface 18 forming the peak 14 and the first locking piece 16, and the lower end 62 of the item 16 is gently pulled out from the gap between the second locking piece 36 and the first locking piece 16. Next, as shown in Figure 7, the tip 64 of the first locking piece 16 is gently pressed, and the second locking piece 36 is pulled up, into which the side end 66 of another item 26 is inserted. By repeating the above procedure, multiple items 26 can be stored in the packaging divider plate 10, as shown in Figure 8. [Industrial applicability]

[0031] The packaging divider of the present invention is useful, for example, as an item for transporting, displaying, and storing various individually packaged items such as confectionery and general merchandise. [Explanation of Symbols]
