The packaging structure may be applied to corrugated cartons, single layer cartons or other types of multi-layer cartons, and the embodiment is not particularly limited.

The structure of the corrugated case is specifically described below based on fig. 1 to 3: the first folded plate 11 is transversely indented according to the height of the contained product and is used as the front of the carton body; the second folded plate 12 is transversely pressed according to the width of the contained product and is used as the bottom surface of the carton body; the third folded plate 13 is transversely indented according to the height of the contained product and is used as the back of the carton body; the fourth folded plate 14 is transversely pressed according to the width of the contained product and is used as the top surface of the carton body; the fifth flap 15 is transversely indented as the front-most portion of the carton body depending on the height of the product contained therein.

In some instances, the first support panel 111 on either side of the first flap 11 is shorter than the width of the product being contained, the first flap 11 is rotated 90 degrees and then pivoted over the transverse indentations, and the first support panel 111 is pivoted over the second flap 12 to support the carton body. Longitudinal indentations are formed in two side edges of the third folding plate 13, the length of the outer side edge of each indentation is smaller than the width of a product to be packed, the third folding plate 13 rotates for 90 degrees along the transverse indentation, and then the third supporting plate 131 rotates along the longitudinal indentations to be bent onto the second folding plate 12 and supports the carton body together with the first supporting plate 11. The longitudinal indentations on the two sides of the third folding plate are larger than the longitudinal indentations on the two sides of the first folding plate by one corrugated plate thickness. Two side edges of the second folded plate 12 are provided with three longitudinal indentations, after the second folded plate 12 is rotated and bent for 90 degrees along the first longitudinal indentation, the inner support plate 1211 is overlapped with the first support plate 111 and the third support plate 131, a clamping part 1215 is arranged between the second crease and the third crease of the second folded plate 12, the clamping part 1215 is thick, the outer support plate 1212 is attached to the first support plate 111 after being bent along the second crease and the third crease, and thus, two ends of the carton box body are respectively provided with four support parts thick of the corrugated board, namely the outer support plate 1212, the first support plate 111, the third support plate 131 and the inner support plate 1211. In addition, the clamping part 1215 covers the top of the supporting part to increase the thickness of a corrugated board plate, so that the reinforcing rib and the limiting effect are achieved, and the strength of the carton body is greatly improved.

In some examples, the insertion portions 1213 at both sides of the second flap 12 are inserted into the corresponding slots 1214 at the bottom of the second flap 12, so that the insertion portions 1213 engage with the slots 1214 after the second flap 12 is bent.

In some examples, the fourth flap 14 has longitudinal indentations on both sides, the reinforcing panel 141 is rotated to overlap the inner side of the fourth flap 14 and glued to form a top surface of two corrugated cardboard panels to increase the strength of the top surface of the carton, and the reinforcing panel 141 preferably covers the latch 1215 to substantially increase the strength of the carton.

In some examples, the fifth flap 15 has longitudinal indentations on both sides and has a curved plug 151. The fifth flap 15 is rotated to be positioned in front of the first flap 11 so that the front of the case has two corrugated cardboard thicknesses, thereby enhancing the strength of the case. The inserting part 151 is inserted into the gap of the supporting plate, so that the sealing operation of the box body can be formed, and the inserting part is not easy to be separated due to vibration after being inserted into the gap due to the matching design.

When the corrugated carton is applied to the lighting box, the reinforcing plate is preferably arranged on the panel side of the lighting box, so that the panel of the lighting box can be effectively protected from being damaged in transportation and loading.

In conclusion, the packaging structure and the corrugated case applied by the packaging structure provided by the utility model are integrally connected and folded, so that the use is very convenient; the lighting box is provided with the first supporting plate, the third supporting plate, the inner supporting plate and the outer supporting plate which are supported by at least four layers, so that the lighting box has high strength, can adapt to the multilayer stacking of the lighting box, can adapt to long-distance transportation, repeated loading and unloading and other transportation links, and can avoid the damage of the loaded product caused by road jolt or external force; the strength of the packaging structure is further improved by arranging the reinforcing plate; the clamping part is arranged above the supporting plate, the reinforcing plate is arranged above the clamping part, the strength of the packaging structure is greatly improved due to the multi-layer overlapping, and the safety of the corresponding product on the side is correspondingly improved (for example, the lighting box panel can be correspondingly packaged, so that the reinforcing plate is positioned above the lighting box panel, and the damage to the lighting box panel in the transportation process can be effectively avoided); and compared with the wooden box, the corrugated case has the advantages of easy manufacture and production, low cost, light weight and convenient storage and transportation.
