Description

Technical Field

[0001] The invention relates to a carton. Background Art

[0002] At present, when packaging materials, due to the different sizes of materials, in order to avoid too large a gap between the product and the carton when packaging, which may cause the product to shake or bump during transportation and cause damage to the product, it is often necessary to add fillers, or multiple layers of cardboard, or bubble bags to the inside of the carton, which increases packaging costs and reduces packaging efficiency. Alternatively, cartons of various specifications are produced to meet usage needs, which is time-consuming and labor-intensive, increases production and processing costs, and is not conducive to improving production and processing efficiency.

[0005] The beneficial effect of such arrangement is that, when in use, the first side panel is folded up and erected, and the combined panel is folded so that the first folded panel in the combined panel is located on both sides of the load-bearing panel, and the third folded panel is folded at the same time so that the two third folded panels are respectively superimposed on the load-bearing panel, which can improve the bottom structure of the box body and the load-bearing capacity. At this time, the second folded panel is not operated to fold first, and the second side panel is further folded so that the second side panel is erected, and the insertion panel is operated to be folded and inserted into the range of the load-bearing panel and attached to the end surface of the third folded panel. The extension panel here can be folded at a selected length according to the size of the loaded material, thereby realizing the limitation of the loaded material and avoiding There is no shaking when loading materials, and no additional filler is required. After the extension plate is folded according to the size of the material, the second folding plate is folded. While the folding plate surrounds the insertion plate, the positioning slot on the second folding plate is inserted into the extension plate to realize the positioning of the extension plate and ensure the stability of the position of the extension plate. Finally, the first cover plate and the second cover plate are folded to seal the box as a whole. The box body is cut and folded into one piece, and no tape is required except for sealing the box. The bottom and sides are both multi-layer cardboard to increase the load-bearing capacity of the carton. The internal size of the carton can be adjusted by the position of different positioning slots on the side, which is suitable for products of multiple sizes.

[0006] As a further configuration of the present invention, a first transition thin plate is provided between the second folding plate and the first folding plate.

[0007] The beneficial effect of such arrangement is that the second insertion plate can be better wrapped by the first transition thin plate, and the position of the extension plate can be fine-tuned to ensure the plug-in effect. At the same time, the structure is simple and has a good use effect.

[0008] As a further configuration of the present invention, a second transition thin plate is arranged between the second side plate and the supporting plate, the second transition thin plate is arranged in a trapezoidal shape, the length of the second side plate is smaller than the length of the supporting plate, the second side plate is connected to the narrow end of the second transition thin plate, and the supporting plate is connected to the wide end of the second transition thin plate.

[0009] The beneficial effect of this arrangement is that it makes folding the second side panel and inserting the insert panel more stable and convenient. At the same time, since the length of the second side panel is shorter than the load-bearing panel, the insert panel can lean against the third folding panel after insertion to form a pre-positioning, which is convenient for subsequent folding operations. The length difference here is only slightly smaller, and the overall length difference is less than 1 cm.

[0010] As a further configuration of the present invention, a clamping groove and a clamping flange are provided between the third folding plates in the two combined plates, and the clamping groove and the clamping flange are clamped to form a fixed connection between the two third folding plates.

[0011] The beneficial effect of such arrangement is that such arrangement further improves the structural strength of the bottom supports of the two, and at the same time the structure is simple, easy to implement, convenient to assemble, and has good reliability in use.

[0012] As a further configuration of the present invention, a connecting groove is provided at the connection between the first folding plate and the second folding plate, a connecting flange is provided at the edge of the second folding plate, and the connecting flange is plugged into and matched with the connecting groove.

[0013] The beneficial effect of such arrangement is that such arrangement ensures the overall stability of the box body after folding, and at the same time, the structure is simple, easy to implement, reliable and convenient to operate, and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
