[0030] In an embodiment of the quick packaging carton structure of the present application, please refer to Figures 1 to 6The quick packing carton structure comprises two first side plates 100 arranged oppositely and two second side plates 200 arranged oppositely. The two first side plates 100 and the two second side plates 200 can form a rectangular frame. The first side plate 100 is connected with the second side plate 200 at a position to form a first crease 101. The first side plate 100 is provided with a first hinge 110 at a top end thereof, and the second side plate 200 is provided with a second hinge 210 at a top end thereof. A bottom plate 300 is arranged between the bottom ends of the two first side plates 100, and the two ends of the bottom plate 300 are connected with the bottom ends of the two first side plates 100 respectively. The bottom plate 300 is provided with a second crease 301. The second side plate 200 is provided with a folding plate 220 arranged at a bottom side thereof, and the folding plate 220 can be folded to the inside of the second side plate 200. The second side plate 200 is provided with a third crease 201, and the upper end of the third crease 201 extends to the top end of the second hinge 210, and the lower end of the third crease 201 extends to the bottom end of the folding plate 220. When the carton is folded, the folding plate 220 is folded to the inside of the second side plate 200, the second side plate 200 is folded along the third crease 201, the two first side plates 100 are adhered to each other, and the bottom plate 300 is folded along the second crease 301, so that the carton is folded into a flat plate structure. When the carton is unfolded, the two second side plates 200 are unfolded along the third crease 201, the two first side plates 100 are separated from each other, the bottom plate 300 is unfolded along the second crease 301 to form the bottom of the carton, and the folding plate 200 is folded downward and adhered to the upper surface of the bottom plate 300.

[0031] The quick packing carton structure of the above embodiment can be unfolded to form an unfolded carton and form the bottom of the carton when the carton is unfolded. The bottom plate 300 is unfolded along the second crease 301 to form the bottom of the carton, and the folding plate 220 is folded downward and adhered to the upper surface of the bottom plate 300 to form the bottom structure of the carton. Therefore, the bottom of the carton does not need to be sealed by a tape, and the operation is simple and convenient, and the efficiency is improved. The carton can be applied to an automatic device to realize automatic unfolding and meet the demand of automation. In addition, the carton can be used repeatedly. After the carton is used (after the goods are taken out from the carton), the carton can be folded again, and the tape at the bottom does not need to be removed, so that the carton is convenient to collect and is convenient to use again.

[0032] Further, the bottom plate 300 and the first side plate 100 can be connected by glue.

[0033] Further, the two sides of the bottom plate 300 are provided with adhesive and are adhered to the inside of the corresponding first side plate 100. In addition, one side of the bottom plate 300 can be integrated with one of the first side plates 100.

[0034] Further, refer to Figure 3 andFigure 4 The side of the bottom plate 300 extends upwardly with a support plate 310. Specifically, the side of the bottom plate 300 which is glued is provided with the support plate 310; while when both sides of the bottom plate 300 are connected with the first side plate 100 by means of gluing, one side of the bottom plate 300 is provided with the support plate 310. The support plate 310 is provided with a fourth crease 311 along the position of the adhesive, and after the carton is unfolded, the support plate 310 is folded along the fourth crease 311 and adheres to the top side of the bottom plate 300, and the side edge of the support plate 310 supports the inner side wall of the other first side plate 100. Thus, the strength of the bottom of the carton can be increased, and in addition, the products in the carton can be supported and buffered, and the products can be protected to a certain extent.

[0035] Further, referring to Figure 3 and Figure 4 , in order to ensure that the support plate 310 remains in a horizontal state, the side of the support plate 310 close to the fourth crease 311 is further provided with a fifth crease 312, and the fourth crease and the fifth crease form a folding part 313 therebetween, which is used to fold to the inner side of the part where the bottom plate 300 is connected with the first side plate 100, so that the support plate 310 can be horizontally adhered to the upper surface of the bottom plate 300.

[0036] Further, referring to Figure 3 and Figure 4 , the side of the folding plate 220 is further provided with a notch for avoiding the folding part 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 part 313. Thus, the bottom of the carton is more stable, and the problem that the carton will shrink along the second crease 301 and the third crease 201 after unfolding is avoided.

[0037] Further, referring to Figure 3 and , when the first hinge 110 is closed in the carton, the free end of at least one first hinge 110 supports the inner side of the first side plate 100. Further, the problem that the carton will shrink along the second crease 301 and the third crease 201 after unfolding is avoided.

[0038] Figure 2 Further, referring to , the side of the first hinge 110 close to the first side plate 100 is provided with a sixth crease 111, and the sixth crease 111 and the first side plate 110 form a downward folding folding part 112. In this embodiment, the first hinge 110 can be folded to sink into the carton, so that the end side of the first hinge 110 can support the inner side wall of the other first side plate 100, and the product in the carton can be pressed by the first hinge 110.

[0039] Further, after the second side plate 200 is folded along the third crease 201, the bottom plate 300 is folded inward along the second crease 301, so that the bottom plate 300 is folded between the two first side plates 100. Thus, the surface area of the carton after folding can be reduced, which facilitates stacking and transportation, and also reduces the effective width of the conveying surface of the automatic packaging production line.

[0040] Further, referring to Figure 7 and Figure 8 , the second crease 301 and the third crease 201 of the flaps are both provided with a perforation, and a portion of the second hinge 210 is also provided with a perforation, which can be torn along the perforation. In the present embodiment, the carton can also be folded into another packaging state. Specifically, when temporarily packaging articles that are longer in length and smaller in width. The carton of the present embodiment can be torn along the perforation, so that the bottom plate 300 and the flaps 220 both form two independent structures. Thus, the second side plate 200 can be folded along the third crease 201 into a right angle, so that one half of the second side plate 200 forms the width of the carton, and the other half forms the length of the carton together with the first side plate 100. And the two separated bottom plates are in a staggered state, but when folded to the bottom, they can close the bottom of the carton. Then another adhesive tape seals the bottom plate of the carton, and another form of carton is formed, which meets the temporary needs.

[0041] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
