Description

[Detailed explanation of the invention] (a) Industrial application field This invention has a lid plate connected to one of the four side plates connected horizontally, and a lid plate connected to the side plate facing the side plate. A reinforcing plate that is tightly folded into the inner surface is connected, and a flap for the inner lid is connected to the other opposing side plate, and the lid plate, reinforcing plate, and flap are folded and assembled into a box shape for delivery. This invention relates to a transportation carton with a flap used for such purposes.

(b) Prior art As for the above-mentioned transportation carton, conventionally, for example, as disclosed in Japanese Utility Model Application Publication No. 19821-1982, the reinforcing plate is made wider than the side plate to which the reinforcing plate is connected.
It is known that the wide portion is folded into the inner surface of the adjacent side plate so that the corner portions are also reinforced.
However, the shipping carton is only used for packaging special items such as water heaters and one-handed pots.
Since the reinforcing plate is made wider than the side plate to which the reinforcing plate is connected, the flap becomes narrower and cannot function as an inner lid.

Therefore, it is common that the width of the reinforcing plate and the width of the side plate to which the reinforcing plate is connected are the same.

(c) Problems to be Solved by the Invention In the conventional general shipping carton with a flap, the flap interferes with the reinforcing plate into which the carton is folded, making it impossible to fold it into the box, and the carton functions as an inner lid. Cartons are destined to be discarded once delivery is complete, but if the carton is sturdy and looks good,
They are often reused as storage boxes for things like mochi and boxes. However, in that case, the flap that serves as the inner lid gets in the way, so it is necessary to cut it out or fold it inward, but conventional products do not have consideration for reuse. When folding inward, the flap cannot be easily folded due to interference between the flap and the reinforcing plate as described above. Furthermore, in the carton cited as the above-mentioned example, although the flap does not interfere with the reinforcing plate, it does not function as an inner lid, and although it can be folded inward, the flap cannot be fixed, which is also the case in the above-mentioned case. There was no consideration given to its use.

(d) Means to solve the problem Therefore, the present invention considers the reuse of conventional general shipping cartons, and the flap can be easily folded and fixed inside after delivery is completed. The purpose of this carton is to provide a shipping carton that can be used for transportation, and its structure is such that perforations are cut inward at the point where it interferes with the reinforcing plate of the flap, extending at least the thickness of the reinforcing plate over the entire length. , and the continuous portion is provided with a notch that reaches the perforation, and the flap is bent into the box to facilitate fixation.

(E) Effect When reusing it as a storage box after delivery is completed, simply push the flap inward, and the part where it overlaps with the upper edge of the reinforcing plate will be bent along the perforation along with the notch. , the flap can be folded into the box without forcing or bending it. In addition, the portion bent along the perforation is tightly fixed to the inner surface of the adjacent side plate, so that it does not get in the way of taking in and out the stored items, and it is possible to obtain a storage box with a clear opening. can.

(F) Embodiment FIG. 1 is a perspective view showing an embodiment of a transportation carton according to the present invention. In FIG. 1, a shipping carton A has a tongue-shaped lid plate 1, and two disc-shaped stops 11 each having a tightening string 13 are attached to the tip thereof. On the other hand, corresponding to the stopper 11, the string 1 is also placed above the front side plate 31.
Disc-shaped fasteners 12, 12 around which the cord 13 is wound are attached, and the lid plate 1 can be fixed in a closed state by winding the string 13 around these fasteners. The carton also has a front side plate 3.
1 is folded back at its upper edge to form a double structure, the front side plate 31 becomes thicker and serves as reinforcement.

Note that the back side plate 6 to which the lid plate 1 is connected, the front side plate 31 and the side side plates 32, 32 facing the back side plate 6 are connected in a horizontally long manner.

2, 2 are flaps extending from the upper edges of the left and right side panels 32, 32, respectively;
The side plate of the front side plate 31 overlaps with the upper edge of the other side plate, that is, the front side plate 31. The front side plate 3 is attached to the side edges of these flaps 2, 2.
Perforation 4 at the point that goes inward by the thickness of 1.
4 is carved along the entire length of the front side plate so that it can be valley-folded, and furthermore, near the fold at the base of the flap, there is a cut 4 parallel to the fold that reaches perforations 4, 4.
1,41 are engraved.

2 and 3 show other embodiments of the invention. The cardboard carton A shown here has a lid plate 1.
The lid body is assembled by folding back the tip of the front side plate 31 inward and fitting separately prepared fixing members 5 into the holes 14 and 15 drilled above the tip portion, the front side plate 31, and the folded reinforcing plate 3. It has a structure that fixes 1.

Incidentally, in FIGS. 2 and 3, the same reference numerals as in FIG. 1 represent the same structures, and the explanation thereof will be omitted.

When the transport carton A configured as described above is to be reused as a storage box after delivery, when the flaps 2, 2 are folded inward, the portions where they overlap with the upper edges of the front side plates 31 will have cutouts 41, 41. Since the flap can be bent along the perforations 4 and 4 (Fig. 3), the flap can be easily folded and stored without having to forcefully bend the flap.
Furthermore, since the portions bent along the perforations 4, 4 press against the front side plate 31, the flaps 2, 2 are fixed inward, and can be used as a storage box with a wide opening for various purposes. This makes it possible to utilize it.

(g) Effects of the invention As described above, according to the invention, when the flap is folded inward, the perforations formed in the flap serve as tight hooks, allowing the flap to be easily bent and fixed inward. Therefore, there is no need to cut off the flaps or forcibly bend them, thereby damaging the aesthetic appearance of the storage box, making it possible to create a recycling box that can be used in a wide variety of ways, even considering the reuse of the carton, which has great practical benefits.
