Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging box that has a resealing function and is suitable for storing confectionery, snack foods, etc.

[Prior art and problems] In carton boxes for storing confectionery, snack foods, etc., the box C is pasted on, and when filling, the contents are stuffed horizontally from the sides as shown in Figure 6 and the flaps are opened. After sealing a ₁ , a ₂ , b ₁ , and b ₂ with adhesive, to take out the contents, tear off the zipper d on the opening part, and if you want to leave the contents, cut the insert piece e in the opening part. It is generally known that the container is inserted into the container f and resealed.

However, in the case of such a general storage box, it is not possible to top-fill the contents. Furthermore, due to structural constraints, it has not been possible to easily form deformed, semicylindrical or trapezoidal carton boxes, and therefore it has not been possible to adopt an effective aesthetic display method.

On the other hand, as a modified box that can be filled from the top, for example, as shown in Fig. 7, a carton box g formed by gluing the four corners of the bottom plate is covered with a lid plate h. . However, with this type of box, the edge of the lid plate h is exposed when the box is sealed, which reduces the aesthetic effect when displayed. Further, when the cover plate h and the side plate i are bonded together, the bonding surfaces tend to fall inward and become deformed, causing inconvenience in the bonding work.

[Means for Solving the Problems] The purpose of the present invention is to solve the problems of the above-mentioned conventional products, and to provide a structure that allows top filling with contents, is easy to assemble, has a resealing function, and has an attractive appearance. The purpose of the present invention is to provide a packaging box that has a good appearance and a high display effect.

In order to achieve the above purpose, this invention provides side plates on both sides of a rectangular top plate, a bottom plate connected to one side in symmetry with the top plate, and end plates connected to both upper and lower edges of the top plate. In addition, in a packaging box formed by gluing a joint piece connected to both the upper and lower edges of the side plate and an end plate, a cut line is carved in a generally U-shape as a whole from the top plate to one side plate, and the package is opened. compartmentalize the pieces;
Further, a folded piece having a groove for inserting an opening piece is adhered to the inner surface of the one side plate, and a bottom plate is adhered to adhesive flaps attached to the upper ends of the one side plate and both end plates. be.

Hereinafter, the configuration of the present invention will be specifically explained based on the drawings.

[Example] Figures 1 to 4 show an example of the present invention. In the developed view of Figure 2, 1 is a flat blank, and 2 is a rectangular blank. Top board,
3 and 4 are side plates connected on both sides of the top plate, 5 is side plate 4
A bottom plate 6 is attached to one side of the side plate 3, and 6 is a folded piece attached to one side of the side plate 3. As shown in the figure, these are attached in one direction. Further, numerals 7 and 8 are end plates that are connected to both the upper and lower edges of the top plate 2, 9 and 10 are joint pieces that are extended to both the upper and lower edges of the side plates 3 and 4,
Reference numerals 11 and 12 denote adhesive flaps attached by extending the upper and lower edges of the end plates 7 and 8, and a U-shaped cut hole 13 is provided at the base of the folded piece 6 to define an adhesive flap 14.

However, in the present invention, the opening piece 15 is sectioned and formed astride the top plate 2 and one side plate 3. This unsealing piece is formed by a cut line 16 carved in a substantially U-shape as a whole so as to span both the top plate and the side plate, and a fold line 17 connecting both ends of the U-shaped cut line. The cut line 16 is preferably formed by a continuous perforation or a perforation line. An insertion piece 18 is provided at the end of the opening piece 15, and an insertion groove 19 corresponding to the insertion piece is provided in the folded book 6.

Incidentally, reference numeral 20 in the figure indicates a plurality of parallel fold lines formed between the top plate 2 and the side plates 3 and 4.

The flat blank of the present invention is constructed as described above, and first, the folded piece 6 is glued onto the side plate 3 with the adhesive flap 14 left uncut. Next, the joining pieces 9, 10 and the end plates 7, 8 are bonded together to obtain a box body with an open top as shown in FIG. In this state, products are filled from the top opening, and then the adhesive flaps 11, 12 and 14 are bent inward and the bottom plate 5 is glued thereon, resulting in a box as shown in FIG.

Displaying the boxes obtained as above in stores,
When opening, turn the entire box over so that it is in the state shown in Figure 4. In this way, the top plate 2 becomes the upper part and the bottom plate 5 becomes the lower part, resulting in a highly stable semicylindrical box.

Furthermore, when opening the package, the top plate 2 is peeled off from the insertion piece 18, the cut line 16 is cut, and the opening piece 15 is bent along the fold line 17. When resealing, use the insert piece 1 provided at the end of the opening piece.
8, inserting the groove 19 and fixing the opening piece 15, the resealing is completed.

Note that the folded piece 6 of the adhesive flap 14 is attached to the side plate 3.
Since it is bonded to the inner surface of the adhesive flap and the adhesive flap is reinforced from the inside by the action of the angle, it is strong unlike conventional adhesive pieces that are easily deformed. Further, since the bottom plate 5 is glued to the adhesive flap 14 and the adhesive flaps 11 and 12 attached to the upper edge of the end plate, the bottom plate 5 exhibits robustness that can sufficiently protect the contents after the box is made.

By the way, although the packaging box of the illustrated embodiment has a structure in which a plurality of parallel fold lines 20 are provided between the top plate 2 and the side plates 3 and 4, these fold lines are not essential to the present invention. Further, the shape of the entire box is not limited to this embodiment, and it goes without saying that it may be shaped as shown in FIG.

[Effects of the invention] As detailed above, the present invention makes it possible to top-fill the contents, seal and reseal the box, and obtain a sturdy box that also looks good when displayed. This has the effect of providing packaging boxes.
