[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-carton capable of collectively packing a large number of products such as cans, and more particularly to a multi-carton that can be automatically packed by a machine.

[0002]

[Prior art]

 As a conventional multi-carton of this type, a multi-carton using a blank plate 1 as shown in FIG. 6 is known. That is, the blank plate 1 is a box in which the side plates 3 and 4 are connected to both side edges of the bottom plate 2 respectively, and the lid plate 5 and the adhesive piece 6 are connected in order to the side edge of one side plate 4. In addition, standing plates 7 are connected in front of and behind the bottom plate 2, respectively. Further, a cover plate 9 which can be curved by a vertical folding curve 8 is provided in front of and behind the side plates 3 and 4, respectively, and the standing plate 7 and the cover plate 9 are connected to each other via a key-shaped folding curve 10, and The cover plate 9 is provided with an inclined folding curve 11 which maintains a predetermined angle with the hook-shaped folding curve 10 or a second inclined folding curve 11a which is arranged in parallel with the inclined folding curve 11 in parallel. Was.

When packing a large number of products with the blank plate 1, as shown in FIG. 7, with the bottom plate 2 as the center, side plates 3 and 4 stand upright, and the lid plate 5 is placed above the products. After attaching the cover piece to the side plate, the sticking piece 6 is stuck to the side plate 3, and then the cover plate 9 is curved along the vertical folding curve 8 and the key-like folding curve 10 and the inclined folding curve 11 are attached to the wife side. By folding and further raising the standing plate 7, the standing plate 7 was attached to the cover plate 9 to assemble the whole and package the product.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional multi-carton, the standing plate 7 and the cover plate 9 are connected to each other through the key-shaped folding curve 10, and the cover plate 9 is inclined with respect to the inclined folding curve 11 or the second folding curve. Since the inclined folding curve 11a is provided, the work of folding and assembling the blank plate 1 by the automatic packing device becomes complicated, and there is a problem that adjustment of the packing device takes time. Therefore, there is a problem that a specific dedicated packing device is required, and it is difficult to easily adjust and cope with the case where the blanking plates of the same type have different sizes. there were. Further, there is a problem that it is difficult to speed up the automatic packing work.

The multi-carton according to the present invention is a new technology developed in view of the above-mentioned conventional problems, and particularly, it includes a cover plate connected to a side plate and a standing plate connected to a bottom plate. The present invention relates to a completely new multi-carton that can be easily and surely bent and can be securely stuck to each other.

[0006]

[Means for Solving the Problems]

 The multi-carton according to the present invention is a technology that has fundamentally improved the above-mentioned conventional problems. The gist of the multi-carton is to connect side plates to both side edges of a bottom plate and to cover and attach one side plate. In a box in which pieces are sequentially arranged, standing plates are respectively arranged at the front and rear edges of the bottom plate, and locking holes are formed at the boundary between the standing plate and the bottom plate, and the locking holes are provided. A cover plate with side projections that can be engaged with the side plates is connected to the front and rear edges of the side plate.When assembling, each cover plate was bent toward the end and the projection was inserted into the locking hole. After that, the multi-carton is characterized in that the standing plate is erected and the cover plate and the standing plate are attached to each other.

[0007]

[Action]

 As described above, the multi-carton according to the present invention is provided with the locking holes at the boundary between the bottom plate and the standing plates that are connected to the front and rear edges of the bottom plate, and is connected to the front and rear edges of the side plates, respectively. Since the protrusion is provided on the side edge of the cover plate, the protrusion of the cover plate can be inserted and locked in the locking hole when the cover plate is bent at a right angle to the wife side. Can be stabilized and its position can be accurately determined. Then, the standing plate and the cover plate can be attached to each other by standing the standing plate outside the cover plate.

【Example】

 An embodiment of a multi-carton according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an assembled perspective view of the carton according to the present invention, FIG. 2 is a plan view of a blank plate of the carton of FIG. 1, and FIG. 2 is a perspective view showing a state where the blank plate of FIG. 2 is assembled, FIG. 4 is a plan view of a blank plate of a carton of another example, and FIG. 5 is an assembled perspective view of the carton of FIG.

In FIG. 2, reference numeral 21 denotes a blank plate for a multi-carton according to the present invention, in which side plates 23 and 24 are connected to both side edges of a bottom plate 22 and one side plate 24 has a side edge. The cover plate 25 and the sticking piece 26 are sequentially connected. In addition, standing plates 27 are continuously provided at the front and rear edges of the bottom plate 22, respectively, and a pair of locking holes 28 are formed at the boundary between the standing plate 27 and the bottom plate 22. A cover plate 29 is continuously provided at the front and rear edges of the side plates 23 and 24, and a protrusion that can be inserted into the locking hole 28 and locked at a side edge of the cover plate 29 near the standing plate 27. The raising 30 is provided so as to project. Further, the lid plate 25 has a pair of finger holes 31 formed therein.

In assembling the multi-carton according to the present invention, as shown in FIGS. 3 and 1, with the bottom plate 22 of the blank plate 21 as the center, side plates 23 and 24 are erected around the bottom plate 22 and the lid plate 25 is bent horizontally upward, and the sticking piece 26 is stuck to the side plate 23. Next, the cover plates 29 are bent at right angles in the front-back direction of the bottom plate 22, that is, toward the end side, and the projections 30 projecting from the cover plate 29 are inserted into the locking holes 28 to lock them. Then, the standing plate 27 is erected on the outer surface of the cover plate 29, and the standing plate 27 is attached to the cover plate 29, whereby the multi-carton can be automatically assembled and configured. Therefore, the structure of the packaging device capable of assembling and automatically packaging the carton according to the present invention can be extremely simplified.

In the above-described embodiment, the projection 30 is provided on the side edge of the cover plate 29, and the locking hole 28 is formed at the boundary between the bottom plate 22 and the upright plate 27. By combining them, the positioning of the cover plate 29 and the stable standing of the cover plate 29 were ensured. However, as in the carton shown in FIGS. 4 and 5, the protrusion 30 and the locking hole 28 described above are provided. It can be omitted. In the carton shown in FIGS. 4 and 5, the leading end portion of the upright plate 27 is formed to have a narrow width, and when assembled, the narrow portion of the upright plate 27 and the leading end portion of the cover plate 29 are mutually disposed. It is configured to be attached. In this case, it is also possible to inflate the carton side to some extent and bend it according to the product to be packed.

[0012]

[Effect of device]

 Since the multi-carton according to the present invention has the above-described structure and operation, it has a simple assembling configuration and can easily pack a large number of products using a general-purpose packing device. Therefore, unlike the conventional multi-carton described above, it is not necessary to use a special packing device, and when carrying out the packing work, the multi-cartons having different shapes and dimensions can be manufactured without the need for a specific complicated fine adjustment. Easy to assemble with a general-purpose machine. Further, when the locking hole and the protrusion are combined, the cover plate can be aligned and stabilized easily and surely.
