Description

The present invention relates to a packaging box having a shape in which a triangular prism is laid down at the time of assembly, and more particularly to a packaging box capable of stably holding a product and easily packaging and taking out the product.

There are various shapes of packaging boxes for storing articles, but a packaging box in which a triangular prism is laid down sideways at the time of packaging is known so as to draw attention to the appearance of the packaging box itself.

For example, the packaging box disclosed in Patent Document 1 wraps a cup of a product, and the cup is further held by an auxiliary paper piece 31 in order to stably fix the cup in the packaging box (Fig. 2, FIG. (Fig. 3), or it was necessary to make the height of the mug of the product equal to the inner height of the triangular pillar (page 6, lines 6 to 9 of the specification).

However, it is preferable to use an auxiliary member as disclosed in Patent Document 1 because not only the manufacturing cost increases but also the labor for packaging the product and taking out the product at the time of opening increases. There was no.

Further, when the packaging box is formed according to the shape and size of the product, it may be difficult to put in and take out the product due to the complicated shape of the packaging box itself. In that respect, in Patent Document 1, the packaging box before packaging is in a completely unfolded state in which no part is attached, and is assembled in a triangular columnar shape from the unfolded state applied when the product is packaged, and is also in a completely unfolded state when opened. It is considered that such a problem does not occur because it can be taken out by returning it to.

However, assembling from a completely unfolded state to a three-dimensional shape in this way is not easy for anyone, especially when the completed shape is a special three-dimensional shape such as a triangular prism. Further, if no part is attached, the strength of the packaging box itself may be weakened, and since the opening of the take-out port is not restricted, the product may pop out during transportation or roll out when opened.

Therefore, it is preferable to attach a part of the special triangular columnar packaging box in a partially assembled state, but if this is done, it cannot be expanded to a completely unfolded state when the product is packaged or taken out. When the packaging box is formed according to the shape and size of the product, it is difficult to package and take out the product.

Therefore, as a packaging box method having such a shape feature, a certain dimensional allowance is given to the product to be stored, and the dimensional allowance is stable without causing rattling of the product. A packaging box capable of holding a product has been desired.

Hereinafter, embodiments of the packaging box of the present invention will be specifically described with reference to the drawings. The present invention is not limited to these embodiments.

FIG. 1 is a developed view of the packaging box 1 according to the present invention. The mount is formed by punching out one blank sheet. As its basic configuration, a bottom plate 21 having four sides, a front plate 22, a back plate 23, a pair of side plates 31 and 32 connected to each side of the bottom plate 21, and two facing the front plate 22 Between the overlapping pieces 4, 6 connected to the sides, the overlapping pieces 5, 7, the side plates 31, 32 connected to the two opposite sides of the back plate 23, and the overlapping pieces 4, 5, 6, 7. A folded piece 8 connected to the back plate 23 and an insertion piece 9 connected to one side of the back plate 23 are provided. In this specification, expressions such as "front", "back", "left and right", and "up and down" do not strictly correspond to the front, back, left, right, and top and bottom of the packaging box 1 and the product to be packaged. It is used for convenience of explanation. Each part will be described in detail below.

As shown in the figure, the bottom plate 21 is formed in a rectangular shape, and a pair of side plates 31 and 32 are connected to two opposing sides thereof. Both the side plates 31 and 32 are formed in a substantially isosceles triangle, and are foldably connected to the bottom plate 21 at a folding line b. The bottom plate 21 of the present embodiment is formed in a rectangular shape, but the shape is not limited to this and may be a square shape.

The front plate 22 and the back plate 23 are connected to the two opposing sides of the bottom plate 21 that is not connected to the side plates 31 and 32. Both the front plate 22 and the back plate 23 are foldably connected to the bottom plate 21 at a folding line a. The front plate 22 and the back plate 23 of the present embodiment are both formed in the same rectangular shape, but the shape is not limited to this and may be a square shape.

Overlapping pieces 4 and 6 are connected to two opposing sides of the front plate 22 that is not connected to the bottom plate 21. Both the overlapping pieces 4 and 6 are foldably connected to the front plate 22 at a folding line c, and each is formed in a substantially trapezoidal shape.

The overlapping piece 4 is formed with a folding line j that extends diagonally diagonally from the corner where the folding line i and the folding line c intersect and reaches the upper side portion of the overlapping piece 4. The overlapping piece 4 is divided into a first region 41 and a second region 42 connected to the folded piece 8 by the folding line j.

Further, the overlapping pieces 4 and 6 have adhesive portions 411 and 611 in a part thereof, and are attached to the front plate 22 in the adhesive portions 411 and 611, but the adhesive portion 411 is provided only in the first region 41. However, it is not provided in the second region 42. That is, since the second region 42 is not attached to the front plate 22, it is freely bendable with respect to the first region 41 attached to the front plate 22 at the folding line j. The adhesive portion 411 is formed closer to the folding line j side, and the adhesive portion 611 is formed closer to the folding line i side. As a result, the portion between the side portions 412 and 612 of the overlapping pieces 4 and 6 to the adhesive portions 411 and 611 is not attached to the front plate 22, and the insertion piece 9 can be inserted between the overlapping pieces 4 and 6 and the front plate 22. Gap is formed.

Overlapping pieces 5 and 7 are connected to two opposing sides of the back plate 23 that is not connected to the bottom plate 21. Both the overlapping pieces 5 and 7 are foldably connected to the back plate 23 at the folding line d, and are formed in a substantially trapezoidal shape.

The overlap piece 5 is divided into a first region 51 and a second region 52 connected to the folded piece 8 by the folding line j.

Further, the overlapping pieces 5 and 7 have adhesive portions 511 and 711 in a part thereof, and are attached to the back plate 23 in the adhesive portions 511 and 711, but the adhesive portion 511 is provided only in the first region 51. The second region 52 is not provided. That is, since the second region 52 is not attached to the back plate 23, it is freely bendable with respect to the first region 51 attached to the back plate 23 at the folding line j. In this embodiment, the overlapping pieces 4, 6, 5, and 7 are provided with adhesive portions, respectively, but it is not necessary to provide the adhesive portions because they function as a packaging box even if such adhesive portions are not provided. Alternatively, any one or three locations of the overlapping pieces 4, 6, 5, and 7 may be arbitrarily selected, and the adhesive portion may be provided only on the selected overlapping pieces.

A folded piece 8 is connected between the side plate 31 and the overlapping pieces 4 and 5, respectively. The folded piece 8 is formed in a triangular shape as a whole, and is foldably connected to the side plate 31 at the fold line g and foldably connected to the overlapping pieces 4 and 5 at the fold line i. Since the folding line i has a deep bending angle at the time of packaging and is inconspicuous as a valley fold, a perforation may be provided to facilitate the folding as in the present embodiment. Further, the folded piece 8 is connected to the first region 81 connected to the side plate 31 and the overlapping pieces 4 and 5 by the folded line h formed so as to extend straight and continuously from the folded line a of the bottom plate 21. It is divided into a second region 82.

Similarly, the folded pieces 8 are also connected between the side plate 32 and the overlapping pieces 6 and 7, respectively. The folded piece 8 is formed in a triangular shape as a whole, and is foldably connected to the side plate 32 at the fold line g and foldably connected to the overlapping pieces 6 and 7 at the fold line i. Since the folding line i has a deep bending angle at the time of packaging and is inconspicuous as a valley fold, a perforation may be provided to facilitate the folding as in the present embodiment. The folded piece 8 is also connected to the first region 81 connected to the side plate 32 and the overlapping pieces 6 and 7 by the bent line h formed so as to extend straight and continuously from the folded line a of the bottom plate 21. It is divided into a second region 82.

Further, the insertion piece 9 is connected to the side of the back plate 23 facing the side connected to the bottom plate 21. The insertion piece 9 is formed so as to be bendable with respect to the back plate 23 at the folding line e. The insertion piece 9 of the present embodiment is divided into a first region 91 connected to the back plate 23 and a second region 92 by a folding line f formed in parallel with the folding line e at an arbitrary portion thereof.

Holes 221 and 231 may be provided in the front plate 22 and the back plate 23. Further, the overlapping pieces 5 and 7 may be formed with cutouts 512 and 712 in accordance with the hole 231. Further, the insertion piece 9 may also be provided with the hole 911 in accordance with the holes 221 and 231. By decorating the holes 221 and 231 with decorations such as tying them through a ribbon or the like at the time of packaging, the aesthetic appearance of the packaging box can be enhanced.

FIG. 2 is a plan view of the state in which the packaging box 1 of the present invention is halfway assembled and before the product is packaged. The packaging box 1 of the present invention is assembled by the following procedure. First, from the unfolded state of FIG. 1, the folding lines b, c, and d are valley-folded, and the side plate 32, the overlapping pieces 6, 7, and the folded piece 8 are folded on the bottom plate 21, the front plate 22, and the back plate 23. Then, the overlapping pieces 6 are attached to the back surface of the front plate 22 and the overlapping pieces 7 are attached to the back surface of the back plate 23 by the adhesive portions 611 and 711 to be fixed. In this specification, the "back surface" is the surface that is inside when the product is packaged.

Next, the folding lines b, c, and d are folded in a valley, and the side plate 31, the overlapping pieces 4, 5, and the folded piece 8 are folded on the bottom plate 21, the front plate 22, and the back plate 23. The side plate 31 and the folded piece 8 are folded so as to overlap a part of the previously folded side plate 32 and the folded piece 8. Then, the overlapping piece 4 is attached to the back surface of the front plate 22 and the overlapping piece 5 is attached to the back surface of the back plate 23 by the adhesive portions 411 and 511 to be fixed. With the above procedure, the assembly up to the state shown in FIG. 2 is completed. By assembling to such a state, the subsequent packaging work of the product becomes easy. Further, by sticking a part in this way, the strength of the packaging box itself is increased, and a beautiful triangular prism can be formed at the time of packaging. Furthermore, by restricting the opening of the take-out port, it is possible to prevent the product from popping out during transportation or rolling out when the product is opened.

FIG. 3 is a perspective view of the packaging box 1 of the present invention when the product is packaged. As shown in the figure, the packaging box 1 has a triangular prism shape that is laid down sideways at the time of product packaging, in other words, a triangular prism shape having either the side plate 31 or 32 as the top surface or the bottom surface.

Hereinafter, a procedure for assembling the packaging box 1 of the present invention into a three-dimensional shape from the flat state of FIG. 2 and packaging the product will be described with reference to FIG. First, the tip end side of the side plate 31 is raised upward. Then, the side plate 32 covered with the side plate 31 is exposed accordingly, so that the tip end side of the side plate 32 is similarly raised upward. At this time, since the overlapping pieces 4, 5, 6 and 7 are fixed to the front plate 22 and the back plate 23, respectively, the front plate 22 and the back plate 22 and the back plate 22 and the back plate 22 increase in distance from the bottom plate 21 at the tip ends of the side plates 31 and 32. The face plate 23 is also pulled in the directions of the side plates 31 and 32 and stands up (FIG. 4a).

As the side plates 31 and 32 are further raised and their standing angles become closer to vertical, the side plates 31 and 32 are separated from each other, and a space for storing goods is formed between them. At this time, the standing angle between the front plate 22 and the back plate 23 also becomes steep.

The product 100 is stored in the space between the side plates 31 and the side plates 32 formed in this manner (FIG. 4b), and the front plate 22 and the back plate 23 are tilted inward until their tips are in contact with each other. For example, a triangular prism-shaped packaging box 1 is formed as shown in FIG.

In the packaging box 1 of the present invention, the first regions 41 and 51, which are a part of the stacked pieces 4 and 5, are attached to the front plate 22 and the back plate 23, respectively, but the second regions 42 and 52. Is foldable from the fold line j, and the first region 81 and the second region 82 of the fold-back piece 8 are also foldably connected to each other at the fold line h. Therefore, in the above series of assembly operations, these are formed. The joining angle between the members can be changed as appropriate, and the work of packaging and putting in and out of products becomes easy.

The packaging box 1 of this embodiment is sealed by the insertion piece 9 in a closed state. Specifically, when the tips of the front plate 22 and the back plate 23 approach each other to a certain distance, the insertion piece 9 is bent at the folding line e, and the tip side thereof is overlapped with the front plate 22 and the side portion 412 of the piece 4 and , It may be inserted into the gap between the front plate 22 and the side portion 612 of the overlapping piece 6.

In the insertion piece 9 of the present embodiment, since the first region 91 and the second region 92 are formed so as to be bendable at the folding line f, the work of locking is easy. That is, first, the second region 92 on the tip side bent at the folding line f is inserted into the gap between the front plate 22 and the overlapping pieces 4 and 6 and temporarily fixed (FIG. 5a). Then, by inserting the remaining first region 91 into the gap between the front plate 22 and the overlapping pieces 4 and 6 (FIG. 5b), the sealing operation can be smoothly performed. The packaging box 1 of the present invention has a cleaner appearance than the conventional packaging box because the insertion piece 9 is completely hidden by the front plate 22 and cannot be visually recognized from the outside in the closed state (FIG. 3). And it is aesthetically pleasing.

Next, an embodiment in which the product is stored in the packaging box 1 of the present invention will be described with reference to FIG. 6A. The products stored in the packaging box 1 are not particularly limited, but here, cosmetics contained in the bottle-shaped container 100 will be taken as an example. The lid 101 of the container 100 is stored in the packaging box 1 on the side plate 31 side, and the bottom surface of the main body 102 is stored on the side plate 32 side. At this time, the fold lines i and j are both valley folds, and the fold line h is a mountain fold. The second region 82 of the folded piece 8 and the second region 42 of the overlapped piece 4 are shaped so as to project into the box with the valley fold line i as the apex. Here, "mountain fold" and "valley fold" are based on the state shown in FIG. The same shall apply hereinafter.

When the product to be stored has a neck 103 confined between the lid 101 and the main body 102 like the container 100, the second region 82 of the folded piece 8 protruding into the box and the second area 82 of the overlapping piece 4 The two regions 42 come into contact with the constricted portion 103, the shoulder portion of the main body 102, and the like, whereby rattling of the container 100 can be prevented and the container 100 can be stably held in the packaging box 1. The second region 82 of the protruding folded piece 8 and the second region 42 of the overlapping piece 4 do not always have to be in contact with a part of the container 100, and have some play with the container 100. The container 100 may be provided so as to come into contact with the container 100 when it is about to move in the packaging box 1.

Further, a different embodiment in which the container 100 is housed in the packaging box 1 of the present invention will be described with reference to FIG. 6 (b). As shown in the figure, in the present embodiment, the folding lines h and i are both valley-folded, while the folding line j is almost unfolded. The first region 81 and the second region 82 of the folded piece 8 are shaped so as to project into the box with the valley fold line h as the apex.

In this embodiment, the first region 81 and the second region 82 of the folded-back piece 8 protruding into the box come into contact with the lid 101, thereby preventing the container 100 from rattling and stably packaging the packaging box. It can be held within 1. The first region 81 and the second region 82 of the protruding folded piece 8 do not always have to be in contact with a part of the lid portion 101, and are provided so as to have some play between the first region 81 and the second region 82. , The container 100 may be provided so as to come into contact with the container 100 when it is about to move in the packaging box 1.

As described above, the packaging box 1 of the present invention can be adapted to the shape and size of the container to be stored by appropriately changing the folding method and angle of the connecting portions of the folded pieces 8 and the overlapping pieces 4 and 5. Since the part protruding into the box can be changed, it is possible to hold the product in an appropriate position.

Further, in each of the embodiments described so far, the overlapping pieces 4 and 5 are divided into the first regions 41 and 51 and the second regions 42 and 52 by providing the folding lines j, but the folding lines j are further overlapped. Pieces 6 and 7 may also be provided, and they may be divided into a first region and a second region. As a result, not only the overlapping pieces 4 and 5 sides but also the overlapping pieces 6 and 7 sides can project those parts into the box to hold the product. Further, by providing the folding line j on the sides of the overlapping pieces 6 and 7, there is an advantage that the opening can be opened wider when the product is taken in and out (FIG. 4b).

The material of the packaging box of the present invention is not particularly limited as long as it is a material used for a general packaging box and can form a triangular prism shape, but the mount is a paper having a certain degree of rigidity. Synthetic resin and the like are preferable. Specifically, Japanese paper, high-quality paper, medium-quality paper, coated paper, cardboard, card paper, coated cardboard, coated card paper, and vapor-deposited paper whose surface is coated with aluminum or aluminum vapor-deposited on synthetic resin. , And synthetic resins such as transparent synthetic resins such as polypropylene and polyethylene tephrate (PET) and opaque synthetic resins can be appropriately used.
