Referring to fig. 1 to 6, in one embodiment of the fast-packing carton structure of the present invention, the fast-packing carton structure includes two oppositely disposed first side panels 100 and two oppositely disposed second side panels 200. The two first side plates 100 and the two second side plates 200 may enclose a rectangular frame. The first fold 101 is formed at a position where the first side panel 100 is connected to the second side panel 200. The top end of the first side plate 100 is provided with a first hinge 110, and the top of the second side plate 200 is provided with a second hinge 210. The bottom between the two first side plates 100 is provided with a bottom plate 300, and two ends of the bottom plate 300 are respectively connected with the bottom ends of the two first side plates 100. The bottom panel 300 is provided with a second fold 301, the bottom side of the second side panel 200 is provided with a folded plate 220, and the folded 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 crease 201, the upper end of the third crease 201 extends to the top end of the second hinge 210, and the lower end extends to the bottom end of the folded plate 220. When the carton is folded, the folded plate 220 is folded to the inner side of the second side plate 200, the second side plate 200 is folded along the third fold line 201, the two first side plates 100 are mutually attached, and the bottom plate 300 is folded along the second fold line 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 fold 201 to separate the two first side plates 100 from each other, the bottom plate 300 is unfolded along the second fold 301 to form the bottom of the carton, and the folded plate 200 is folded down and attached to the upper surface of the bottom plate 300.
In the fast-packing carton structure of the above embodiment, when the carton is unfolded, the two second side panels 200 are unfolded along the third crease 201 to separate the two first side panels 100 from each other, and at the same time, the bottom panel 300 is unfolded along the second crease 301 to form the bottom of the carton, and the folded plate 220 is folded down and attached to the upper surface of the bottom panel 300, thereby forming the bottom structure of the carton. The open carton can be formed by only expanding the carton along the corresponding crease, and the bottom of the carton is formed. Therefore, the bottom is not required to be sealed by using an adhesive tape, the operation is simple and convenient, and the efficiency can be improved. Moreover, the carton can be applied to automatic equipment to realize automatic unfolding, so that the requirement of automation is met. In addition, this carton can also make things convenient for a lot of utilization, and specifically, after the carton uses to accomplish (take out the goods from the carton after), can fold the carton again, then need not the sticky tape scheduling problem of dismantling the bottom, it is very convenient to collect, the reutilization of being convenient for.
Further, the bottom plate 300 and the first side plate 100 may be coupled by glue for the purpose of convenience in processing the paperboard and saving materials.
Further, both sides of the bottom plate 300 are provided with an adhesive, and are adhered to the inner side of the corresponding first side plate 100. In addition, one side of the bottom plate 300 may be formed integrally with one of the first side plates 100.
Further, referring to fig. 3 and 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 base plate 300, and when both sides of the base plate 300 are connected to the first side plate 100 by gluing, the support plate 310 is provided on the glued side of the base plate 300. The support plate 310 is provided with a fourth crease 311 along the adhesive, after the carton is unfolded, the support plate 310 is folded along the fourth crease 311 and attached to the top side of the bottom plate 300, and the side edges of the support plate 310 are supported on the inner side walls of the other first side plate 100. Therefore, the strength of the bottom of the paper box can be increased, and in addition, the paper box can also play a role in supporting and buffering the articles in the paper box, and a certain protection effect can be played on the packaged articles.
Still further, referring to fig. 3 and 4, in order to ensure the horizontal state of the support plate 310, a fifth fold 312 is further provided on a side of the support plate 310 adjacent to the fourth fold 311, and a fold 313 is formed between the fourth fold and the fifth fold for folding to an inner side of a connection portion of the bottom plate 300 and the first side plate 100, so that the support plate 310 can be horizontally attached to an upper surface of the bottom plate 300.
Further, referring to fig. 3 and 4, a notch is further formed on one side of the folded plate 220 for avoiding the folding portion 313, and when the folded plate 220 is folded to the top side of the supporting plate 310, the side wall of the notch presses the folding portion 313. Thereby making the bottom of the carton more stable. And avoids the problem of shrinkage of the carton along the second fold 301 and the third fold 201 after deployment.
Further, referring to fig. 3 and the spout, when the first hinge 110 is closed in the carton, the free end of at least one first hinge 110 is supported on the inside of the first side panel 100. Further avoiding the problem of shrinkage of the carton along the second fold 301 and the third fold 201 after deployment.
Further, referring to fig. 2 and fig. 2, a sixth fold 111 is disposed on a side of the first hinge 110 near the side connected to the first side board 100, and a fold position 112 is formed between the sixth fold 111 and the first side board 110. In this embodiment, the first hinge 110 can be folded and then can be sunk into the box, so that the end side of the first hinge 110 can be supported to the inner side wall of the other first side plate 100, and the first hinge 110 can be utilized to press the product in the carton.
Further, after the second side panel 200 is folded along the third fold 201, the bottom panel 300 is folded along the second fold 301, so that the bottom panel 300 is folded between the two first side panels 100. Thereby the surface area after the carton is folded can be reduced, and then convenient stack and transportation to can also reduce the effective width of the transport face of automatic packing production line.
Further, referring to fig. 7 and 8, the second fold 301 and the third fold 201 of the flap are each provided with a point line of weakness, and a portion of the second hinge 210 is also provided with a point line of weakness and is tearable along the point line of weakness. In this embodiment, the carton may also be folded into another packaged condition. In particular, when temporarily packaging articles of greater length and lesser width. The carton of this embodiment can be torn along the point line of weakness such that the bottom panel 300 and the flap 220 both form two separate structures, and therefore the second side panel 200 can be folded at a right angle along the third fold 201 such that half of the second side panel 200 forms the width of the carton and the other half forms the length of the carton with the first side panel 100. And the two separated bottom plates are in a dislocation state, but can close the bottom of the paper box when folded to the bottom. And the bottom plate of the paper box is sealed by another adhesive tape, so that the paper box in another form is formed, and the temporary requirement is met.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
