[0030] In one embodiment of the carton structure for rapid packaging of the present invention, please refer to Figures 1 to 6, a carton structure for quick packaging, comprising two first side panels 100 arranged oppositely and two second side panels 200 arranged oppositely. The two first side panels 100 and the two second side panels 200 can enclose a rectangular frame. The first fold 101 is formed at the position where the first side panel 100 and the second side panel 200 are connected. A first hinge 110 is provided at the top of the first side panel 100, and a second hinge 210 is provided at the top of the second side panel 200. A bottom plate 300 is provided at the bottom end between the two first side panels 100, and the two ends of the bottom plate 300 are respectively connected to the bottom ends of the two first side panels 100. The bottom plate 300 is provided with a second fold 301; a folding plate 220 is provided at the bottom side of the second side panel 200, and the folding plate 220 can be folded to the inner side of the second side panel 200. The second side panel 200 is provided with a third fold 201, and the upper end of the third fold 201 extends to the top of the second hinge 210, and the lower end extends to the bottom end of the folding plate 220. When the carton is folded, the folding plate 220 is folded to the inner side of the second side panel 200, the second side panel 200 is folded along the third fold 201, and the two first side panels 100 are attached to each other, and the bottom panel 300 is folded along the second fold 301, so that the carton is folded into a flat plate structure. When the carton is opened, the two second side panels 200 are unfolded along the third fold 201, so that the two first side panels 100 are separated from each other, the bottom panel 300 is unfolded along the second fold 301 and forms the bottom of the carton, and the folding plate 200 is folded downward and attached to the upper surface of the bottom panel 300.

[0031] In the above-mentioned embodiment of the fast packing carton structure, when the carton is unfolded, the two second side panels 200 are unfolded along the third fold 201, so that the two first side panels 100 are separated from each other, and at the same time, the bottom plate 300 is unfolded along the second fold 301 to form the bottom of the carton, and the folding plate 220 is folded downward and attached to the upper surface of the bottom plate 300, thereby forming the bottom structure of the carton. Since it is only necessary to unfold the carton along the corresponding fold to form a stretched carton and form the bottom of the carton. Therefore, there is no need to use tape to seal the bottom, the operation is simple and convenient, and the efficiency can be improved. Moreover, the carton of the present invention can be applied to automated equipment to realize automatic unfolding and meet the needs of automation. In addition, the carton can also be conveniently used multiple times. Specifically, after the carton is used (after the goods are taken out of the carton), the carton can be folded again, so there is no need to remove the tape at the bottom, etc., and the collection is very convenient and convenient for secondary use.

[0032] Furthermore, in order to facilitate the processing of the paperboard and save materials, the bottom plate 300 and the first side plate 100 can be connected by glue.

[0033] Furthermore, adhesive is provided on both sides of the bottom plate 300 and is adhered to the inner side of the corresponding first side plate 100. In addition, one side of the bottom plate 300 may also be a structure that is integrated with one of the first side plates 100.

[0034] Further, refer to Figure 3 and Figure 4 , a support plate 310 extends upward from one side of the bottom plate 300. Specifically, the support plate 310 is provided on the glued side of the bottom plate 300; and when both sides of the bottom plate 300 are connected to the first side plate 100 by gluing, the support plate 310 is provided on one side of the bottom plate 300. The support plate 310 is provided with a fourth fold 311 along the position of the adhesive. After the carton is opened, the support plate 310 is folded along the fourth fold 311 and attached to the top side of the bottom plate 300, and the side edge of the support plate 310 is supported on the inner side wall of the other first side plate 100. Thereby, the strength of the bottom of the carton can be increased, and it can also support and cushion the items in the carton, and can provide a certain degree of protection for the packaged items.

[0035] Further, refer to Figure 3 and Figure 4 In order to ensure that the support plate 310 remains horizontal, a fifth fold 312 is further provided on the side of the support plate 310 close to the fourth fold 311, and a folding portion 313 is formed between the fourth fold and the fifth fold for folding to the inner side of the connecting portion between the bottom plate 300 and the first side plate 100, so that the support plate 310 can be horizontally attached to the upper surface of the bottom plate 300.

[0036] Further, refer to Figure 3 and Figure 4 A notch is also provided on one side of the folding plate 220 to avoid the folding portion 313, and when the folding plate 220 is folded to the top side of the support plate 310, the side wall of the notch presses the folding portion 313. This makes the bottom of the carton more stable and avoids the problem of the carton shrinking along the second fold 301 and the third fold 201 after unfolding.

[0037] Further, refer to Figure 3 When the first hinge 110 is closed on the carton, the free end of at least one first hinge 110 is supported on the inner side of the first side panel 100. This further avoids the problem that the carton will shrink along the second fold 301 and the third fold 201 after being unfolded.

[0038] Further, referring to FIG. Figure 2 A sixth fold 111 is provided on the side of the first hinge 110 close to the connection with the first side panel 100, and a folding position 112 folded downward is formed between the sixth fold 111 and the first side panel 110. In this embodiment, the first hinge 110 can be sunk into the box body after being folded, so that the end side of the first hinge 110 can be supported by the inner side wall of the other first side panel 100, and the first hinge 110 can be used to press the products in the carton.

[0039] Furthermore, after the second side panel 200 is folded along the third fold 201, the bottom panel 300 is folded inward along the second fold 301, so that the bottom panel 300 is folded between the two first side panels 100. Thus, the surface area of ​​the folded carton can be reduced, thereby facilitating stacking and transportation, and also reducing the effective width of the conveying surface of the automated packaging production line.

[0040] Further, refer to Figure 7 and Figure 8 , the second fold 301 and the third fold 201 of the folding plate are both provided with a dotted line, and part of the second hinge 210 is also provided with a dotted line, and can be torn along the dotted line. In this embodiment, the carton can also be folded into another packaging state. Specifically, when temporarily packaging items with a longer length and a smaller width. The carton of this embodiment can be torn along the dotted line, so that the bottom plate 300 and the folding plate 220 form two independent structures, so that the second side plate 200 can be folded into a right angle along the third fold 201, so that half of the second side plate 200 forms the width of the carton, and the other half forms the length of the carton with the first side plate 100. And the two separated bottom plates are in a dislocated state, but when folded to the bottom, the bottom of the carton can be closed. Then another tape is used to seal the bottom plate of the carton, so that another form of carton is formed to meet temporary needs.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
