[0001]

[Industrial applications]

 The present invention relates to a carton that is easy to assemble and can be crushed into a flat shape after use.

[0002]

[Prior Art]

 Conventionally, cartons that store products have generally been constructed by folding cardboard. In particular, the carton that stores gifts and so on is generally formed by folding the cardboard in a complicated manner to form a carton with a good appearance. As a carton having a simple structure, for example, the publicly known Japanese Utility Model Laid-Open No. 61-178316 or the technique shown in FIG. In this carton, centering on the bottom plate 1, side plates 2 and 2 and peripheral girder plates 3 and 3 having tongues 3a and 3a at both ends are continuously provided around the bottom plate 1, and when the carton is assembled, the tongues 3a and 3a are This is a technique in which a carton is assembled by applying a spot-shaped adhesive to 3a and attaching the tongue pieces 3a, 3a to the side plates 2, 2.

[0003]

[Problems to be solved by the device]

 However, since the carton used for gifts and the like mentioned above has a complicated structure, it takes time to assemble the carton, and it is bulky after use and has a problem of disposal. In particular, when trying to dismantle a flat shape, the folding structure becomes complicated, so there is a problem that it is difficult for an amateur to dismantle, and it takes time. Also, the technology described in Japanese Utility Model Laid-Open No. 61-178316 or in FIG. 5 described above is a simple carton with a relatively simple structure and spotted adhesive parts. There was a problem that dismantling and forming into a flat shape required skill, and it was difficult for women and women to handle easily.

The carton according to the present invention is a completely new technology developed in view of the above-mentioned conventional problems. In particular, the whole structure has an extremely simple structure and a diagonal bending curve. A flap that can be folded in two in a triangular shape is connected to both ends of the side plate, and the flap is attached to the inner surface of the gable plate, whereby when the gable plate is erected, the flap is folded in two in a diagonal folding curve, In addition, it is a technology that allows the side plate with the flaps to be automatically erected to form a box, or the box once formed can be easily crushed into a flat shape.

[0005]

[Means for Solving the Problems]

 The carton according to the present invention is a technology that has fundamentally improved the above-mentioned conventional problems, and the gist thereof is a diagonal folding line in a box in which side plates and end plates are connected to the peripheral edge of the bottom plate. A flap that can be folded in two in a triangular shape is continuously provided at both ends of the side plate, and a folded overlapping plate is continuously provided at the tip of the end plate, and the tip of the flap is attached to the inner surface of the end plate. It is a carton with a crash function.

[0006]

[Action]

 As described above, the carton according to the present invention is a box in which the side plate and the end plate are connected to the peripheral edge of the bottom plate, and flaps that can be folded in two in a triangular shape through diagonal folding curves are provided at both ends of the side plate. Since the flaps were connected in series, and the flaps were abutted on the inner surface of the gable plate, and the tip of the flap was attached to the gable plate, when the gable plate was erected, the flap was folded in two diagonally, and The side plate to which this flap is connected can be automatically erected to form a box. Since a folded overlapping plate was connected to the tip of the gable plate, by folding and stacking this inside the gable plate, the two-folded flap was clamped and fixed between the gable plate and this bent overlapping plate, and stable. It is possible to construct a carton in a broken state. In addition, the flaps sandwiched between the folded overlapping plates are opened by opening the folded overlapping plates outward from the inside of the end plate, whereby the end plates, the flaps, and the side plates are individually collapsed to flatten the entire carton. Can be crushed.

【Example】

 An embodiment of the carton according to the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of the carton according to the present invention, FIG. 2 is a developed plan view of the carton according to the present invention, and FIG. FIG. 4 is a plan view showing a state of being flatly folded during assembly, and FIG. 4 is a perspective view during assembly with the carton raised.

The blank board of the carton according to the present invention will be described with reference to FIG. 2 as follows. Reference numeral 1 denotes a bottom plate, and left and right side plates 2 and 2 are connected to each other via a folding curve. Further, gable plates 3 and 3 are arranged above and below the bottom plate 1 via folding curves, respectively. Flaps 4 and 4 are continuously provided on the upper and lower ends of the side plates 2 and 2, respectively. These flaps 4 and 4 are formed so that they can be folded in two in a triangular shape by a diagonal folding curve 5 connecting corresponding pairs of corners. Adhesive glue 6 is applied in spots on the tips of the flaps 4 and 4 that are divided in two by the diagonal folding curve 5. A bent stacking plate 7 is connected to the end portions of the end plates 3, 3.

In the assembling construction of the carton according to the present invention, first, as shown in FIG. 2, the side plates 2 and 2 on both sides are folded on the bottom plate 1 and the flaps connected to both ends of the side plates 2 and 2 are connected. 4, 4 are brought into contact with the inner surface of the end plate 3, and the front end portions of the flaps 4, 4 are attached to the end plate 3 with an adhesive glue 6. In this state, as shown in FIG. 4, when the end plate 3 is vertically erected along the bottom plate 1, the flaps 4 and 4 are folded in half along the diagonal folding curve 5, and the side plates to which the flaps 4 and 4 are connected are folded. 2 and 2 can be automatically vertically stood along the bottom plate 1.

After that, the folded overlapping plates 7, 7 are folded inside the gable plates 3, 3 so that the flaps 4, 4 are sandwiched between the gable plates 3, 3 and the folded overlapping plates 7, 7, respectively, and stabilized. The carton of the structure can be assembled and assembled.

When the carton according to the present invention is formed into a flat shape again, the flaps 4 and 4 are opened by opening the folded overlapped plates 7 and 7 that have been folded inside the gable plates 3 and 3. At the same time as returning the original to the original state, the gable plates 3 and 3 and the side plates 2 and 2 are respectively pushed down, whereby the entire carton can be crushed into a flat shape.

[0012]

[Effect of the device]

 Since the carton according to the present invention has the structure and operation as described above, the flap attached to the inner surface of the end plate is folded in two, and the flap is sandwiched between the end plate and the folding overlapping plate, thereby forming the carton. Can be easily assembled and configured. In addition, by opening the folded and overlapped plate that was folded and overlapped inside the gable plate, the flap that was folded in two was opened, and by this, the gable plate and the side plate were laid down, and the whole plate was easily crushed and flattened. Can be Therefore, the carton can be stored or discarded without taking up space. Further, in the carton according to the present invention, since it is not necessary to provide an oblique bending line on a part of the side plate or the end plate, the wall surface of the carton can be stood upright in a straight line and the strength of the entire carton can be hindered. Absent. Since the carton of the present invention has a simple overall structure, it requires a small area of material, is easy to assemble, and has the characteristics that it can be mass-produced at low cost.
