Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a packaging box, and in particular to a packaging box in which a product storage space is opened and closed by a pair of top flaps and which can be resealed.

``Prior art'' As a type of packaging box, as shown in the example in Figure 7,
Side plates 21 and top flaps 22 at both ends of the bottom plate, respectively.
are sequentially connected so that they can be folded, and folded pieces 23, 24, 25 are provided on both sides of these pieces, respectively.
The main body sheet 26 is arranged to be bendable and can be bent into a rectangular tube shape as a whole, and the storage space formed within the rectangular tube-shaped body sheet 26 is partitioned into a plurality of parts, and connection pieces 27 are provided on both sides. There is one that is composed of an H-shaped partition body 28. This packaging box is constructed by placing the partitions 28 on the bottom plate of the main body sheet 26 and folding the main body sheet 26 so as to wrap around the partitions 28.
Each folded piece 23, 2 is attached to the outside of the connection piece 27 of 8.
By covering 4 and 25 and fixing them,
Both sides of the rectangular cylindrical main body sheet 26 are closed by connecting pieces 27 of the partition body 28, and can be formed from sheets by a relatively simple assembly process, making manufacturing easy. It has the following characteristics.

``Problem that the invention aims to solve'' By the way, when products are stored in packaging boxes for transportation, etc., it is necessary to open and reseal them during the distribution process for purposes such as pricing. However, in the case of the packaging box, the connection piece 27 of the partition 28 and each folded piece 23, 24, 2
5 are firmly fixed to each other, it is necessary to peel off the folded piece 25 of the top flap 22 when opening the bag, and re-glue it when resealing, resulting in a problem of poor workability.

This invention was proposed in view of the above circumstances.
The purpose is to provide a packaging box that is easy to open and reseal.

``Means for Solving the Problems'' The present invention has a top flap that can be inserted into the storage space by being folded and overlapped with each other when the storage space is closed, at the tip of each top flap. It is characterized in that thinner extra long pieces are arranged in a row so as to be bendable, and the extra long pieces are overlapped with each other, and the folded pieces are placed over the other opposing side plate and fixed by pasting to close off the storage space. .

``Function'' When the packaging box of the present invention is sealed, the storage space is closed by overlapping the extra lengths of both top flaps, and the folded pieces are fixed, and when the packaging box is opened, the top flaps are closed. Separate the folded piece from the perforation, open the top flap, and
When resealing, the resealed state can be maintained by bending the extra length of the top flap inward and inserting it into the storage space.

“Example” An example of the packaging box of the present invention will be described below based on FIGS. 1 to 6. This packaging box also has the following features:
Similar to FIG. 7, the structure is a combination of a main body sheet 1 made of corrugated cardboard and folded into a rectangular tube shape, and a partition body 3 that partitions an internal storage space 2 into a plurality of sections.

The main body sheet 1 has a bottom plate 4 as shown in FIG.
A side plate 5 and a top flap 6 are sequentially connected to both ends of the top flap 6 in a bendable manner, and on both sides of each of the bottom plate 4, the side plate 5, and the top flap 6,
It has a basic configuration in which folded pieces 7, 8, and 9, all of which have the same width _W1 , are arranged so as to be foldable, and can be folded into a rectangular tube shape so that both top flaps 6 are turned inward. The length of the flap 6 on both sides _{is 1}
is set to 1/2 of the length ₂ of the bottom plate 4, and extra long pieces 10 are bendably provided at the tips thereof so as to overlap each other when the main body sheet 1 is bent into a rectangular tube shape. This extra length piece 10
The cardboard is crushed so that the thickness is, for example, half that of other parts such as the top flap 6.

Further, perforations 11 are provided between the both top flaps 6 and the folded pieces 9 on both sides, so that these can be separated, and the center part of the bottom plate 4 and the folded pieces 7 on both sides is A division guiding path 12 made of perforations, cut tape, etc. is provided so as to cross the direction, so that the main body sheet 1 can be divided into left and right halves.

On the other hand, as shown in FIG. 3, in the partition 3, a connecting piece 14 is formed by making a notch 13 in the center of both widthwise ends of the cardboard along the width direction, and from the notch 13 as shown by the arrow. By folding the connecting pieces 14 in half and spreading the connecting pieces 14 on both sides to the left and right, the whole is formed into an H-shape as shown in FIG.
A divided guideway 15 is provided with breakable perforations so as to connect the two. The width W ₂ of the entire partition 3 when formed into an H-shape is approximately the same as the width W ₃ of the bottom plate 4, and the length ₃ of each connection piece 14 spread left and right and the side plate 5 The sum of the width W ₁ of the folded piece 8 is 1/2 of the length ₂ of the bottom plate 4.
It is said that

When assembling a packaging box configured in this way, the divided guideway 1 in the center of the bottom plate 4 of the main body sheet 1 is
2 on the line shown by arrow A in Fig. 2.
is placed thereon, both side plates 5 are stood up so as to wrap around the partition 3, and each folded piece 8 is bent inward to connect the tip of the folded piece 8 and the connection piece 14 of the partition 3. By butting them together, another opposing side plate is formed that closes both sides of the storage space 2 between the side plates 5, and then the folded pieces 7 of the bottom plate 4 are bent to form the connecting piece 14 and the folded pieces in the abutted state. 8 and are joined together using adhesive, staples, etc., to assemble the packaging box as shown in FIG.

In the packaging box assembled in this way, the product is stored in the storage space 2 partitioned by the partition 3, both top flaps 6 are closed, and the folded piece 9 is connected to the folded piece 8 of the side plate 5 and the connecting piece of the partition 3. 14, and by joining these together, it can be transported in a sealed state as shown in FIG. 4. In this sealed state, the extra length 10 of the top flap 6 is Since they overlap each other, the intrusion of dirt, dust, etc. can be prevented without sealing the space between them with tape or the like, and dirt on the products in the storage space 2 can be effectively prevented. In this case, since the extra long pieces 10 are crushed and made thinner, even when they are overlapped, protrusion can be suppressed, the top surface of the box can be flattened, and the packaging box can be stabilized. Can be stacked in any condition. In addition, since the ends of the connecting piece 14 of the partition 3 and the folded piece 8 of the side plate 5 are butted against each other to close both sides of the packaging box, the inner surface of the packaging box becomes flat and the interior of the storage space 2 is No convex portions are formed in the storage space 2, the storage space 2 can be utilized to the maximum, and even square products can be easily stored.

On the other hand, when opening the bag, after separating the top flap 6 and its folded piece 9 by breaking the perforation 11 between them, the fifth flap 6 is opened by rotating both top flaps 6 into a so-called double-fold shape.
As shown in the figure, the upper part of the packaging box can be left open. In this way, once the packaging box is opened, the top flap 6 and folding piece 9 are separated along the perforations, so it is clearly displayed that the packaging box has been opened, and fraud is prevented. Can prevent opening. If the package is to be resealed after opening, this can be done by folding the extra long pieces 10 of both top flaps 6 inward and inserting them into both sides of the partition 3, as shown in FIG. be. In this case, since the extra length piece 10 is thin, it is easy to insert it.

In the illustrated example, the bottom plate 4, the partition body 3, etc. are divided into left and right parts by cutting the divided guiding paths 12 and 15 of the main body sheet 1 and the partition body 3, and the packaging box is divided into two small packages. Although it can be divided into boxes, extra long pieces 10 are provided on each of the pair of top flaps 6, and these extra long pieces 10 are used as partitions 3.
Since the package is resealed while inserted on both sides of the package, even after the packaging box is divided into two, each can maintain its sealed state. In this case, it is possible to divide after resealing or to reseal after dividing.

Furthermore, in this packaging box, since the connecting piece 14 of the partition body 3 and the folded piece 8 of the side plate 5 are assembled by butting their tips against each other, the main body sheet 1 has a substantially rectangular shape as shown in FIG. is formed. Incidentally, in the conventional example shown in FIG.
In order to avoid overlapping each other and triple thickness of the packaging box when it is placed over the outside of the connecting piece 27 of However, in the packaging box according to the embodiment of the present application, there is no need to provide such a notch, and it is possible to eliminate waste and use materials efficiently.

The present invention can also be applied to the packaging box shown in FIG. 7, in which the top flap 22
By arranging an extra long piece at the tip of the flap and providing a perforation between the top flap 22 and the folded piece 25, resealing becomes possible. In short, it has a pair of top flaps, a foldable piece is provided on the top flap through a perforation, and an extra long piece that can be folded to overlap when the storage space is closed is provided. It would be fine if it was.

"Effects of the Invention" As explained above, the packaging box of the present invention can provide the following effects.

(i) The folded piece of the top flap can be sealed by fixing it to the other side plate, and it can be opened by cutting the perforation between the top flap and the folded piece, and the extra length of the top flap can be sealed. By folding the piece inward and inserting it into the storage space, it can be resealed, making the series of opening and resealing operations easier and improving the workability of pricing and the like.

(ii) By closing both flaps with the extra long pieces overlapping each other, it is possible to prevent the intrusion of dirt and dust without sealing the space between them with tape, etc., and prevent dirt on the product. It can be effectively prevented.

(iii) Folded pieces are arranged on both sides of the top flap through breakable perforations, and these folded pieces are covered and fixed to the other opposing side plate to close off the storage space. When opening the box, the top flap and folding piece are automatically separated along the perforations. Therefore, with the packaging box of the present invention, it can be clearly determined from the appearance whether the packaging box has been opened or not, and unauthorized opening can be prevented.

(iv) Since the thickness of the extra long piece is formed to be thinner than the top flap, this part can be prevented from rising when the extra long pieces are overlapped, and the top surface of the packaging box can be flattened. Therefore, the packaging boxes of the present invention allow the packaging boxes to be stacked in a stable manner.
