[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] At present, cartons have the following shortcomings:

[0034] 1. Ordinary slotted cartons need to be sealed with tape, which is not environmentally friendly;

[0035] 2. The bottom is uneven and needs to be leveled, but the bearing capacity is average.

[0036] 3. In the cartons in the related art, the width of the long side flap of the top of the carton needs to be the same as the width of the carton, which wastes costs.

[0037] Therefore, the utility model provides a carton to solve the above technical problems one by one.

[0038] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0039] According to an embodiment of the utility model, on the one hand, a carton is provided, comprising a carton body 1 and a load-bearing structure 3 arranged at the bottom of the carton body 1, the load-bearing structure 3 comprising an inner bottom plate 31, an outer bottom plate 32 and two folding plates 33. The inner bottom plate 31 is arranged on the inner side of the carton body 1; the outer bottom plate 32 is arranged on the outer side of the carton body 1; the side edges of the two folding plates 33 that are away from each other are respectively connected to the two side edges of the outer bottom plate 32, and the two folding plates 33 are pressed on the inner bottom plate 31.

[0040] Specifically, the carton body 1 has a rectangular accommodating cavity, the load-bearing structure 3 is located at the bottom of the carton body 1, and the articles are placed on the load-bearing structure 3, which plays a load-bearing role. The load-bearing structure 3 includes an outer bottom plate 32, an inner bottom plate 31 and two folding plates 33, forming a three-layer load-bearing plate at the bottom, which has a strong load-bearing capacity. Since the folding plates 33 are connected to the outer bottom plate 32 and pressed on the inner paperboard, the articles are pressed on the folding plates 33. The heavier the article, the greater the pressure on the folding plates 33, the tighter the bottom load-bearing structure 3 is pressed, and the stronger the load-bearing capacity. With this load-bearing structure 3, it is possible to achieve load-bearing without the need for tape fixation, which is both environmentally friendly and improves the load-bearing capacity of the bottom.

[0041] In one embodiment, the carton body 1 includes two oppositely disposed first side panels 11 and two oppositely disposed second side panels 12, the inner bottom panel 31 and the outer bottom panel 32 are respectively connected to the two first side panels 11, and insertion gaps 34 are provided on both sides of the inner bottom panel 31 and between the two second side panels 12, and the insertion gaps 34 are for the folding plates 33 to pass through.

[0042] Since the insertion gaps 34 are provided between the two sides of the inner bottom plate 31 and the two second side plates 12, the folding plates 33 connected to the outer bottom plate 32 can pass through the insertion gaps 34 on both sides, and be folded and pressed on the inner bottom plate 31. In this way, the outer bottom plate 32 and the two folding plates 33 can be cut and formed as one piece.

[0043] In one embodiment, for the connection edge between the inner bottom plate 31 and the first side plate 11 , two ends of the inner bottom plate 31 are shorter than two ends of the first side plate 11 .

[0044] When the two first side panels 11 and the two second side panels 12 are connected end to end to form a closed rectangular parallelepiped, the inner bottom panel 31 has two ends shorter than the two ends of the first side panel 11 . Therefore, a gap is formed between the inner bottom panel 31 and the second side panel 12 , and the gap can form the above-mentioned insertion gap 34 .

[0045] In one embodiment, the length of the first side plate 11 is greater than the length of the second side plate 12 .

[0046] The two first side panels 11 and the two second side panels 12 can form a square cavity when connected end to end. When the length of the first side panel 11 is equal to the length of the second side panel 12, the carton body 1 forms a cube structure. In this embodiment, the length of the first side panel 11 is greater than the length of the second side panel 12, then the carton body 1 forms a rectangular structure.

[0047] In one embodiment, the two flaps 33 do not overlap each other.

[0048] The two folding plates 33 do not overlap each other, which can ensure that the bottom will not be uneven due to overlap after the two folding plates 33 are pressed on the inner bottom plate 31, and can also avoid material waste and save costs.

[0049] In one embodiment, it also includes a covering structure 2 arranged on the top of the carton body 1, and the covering structure 2 includes two oppositely arranged first flaps 21 and two oppositely arranged second flaps 22, the first flaps 21 are connected to the first side panel 11, and the second flaps 22 are connected to the second side panel 12, the two first flaps 21 are arranged on the outer surfaces of the two second flaps 22, and the two first flaps 21 are buckled and connected by multiple buckling structures.

[0050] The cover structure 2 is located at the top of the carton body 1. Articles are loaded into the accommodating cavity of the carton body 1 and sealed by the cover structure 2. The first swing cover 21 and the second swing cover 22 are buckled and connected by multiple buckling structures, which can achieve self-locking and tape-free fixation, which is reliable and environmentally friendly. In addition, due to the buckling structure, the first swing cover 21 and the second swing cover 22 are connected by the buckling structure, and the first swing cover 21 or the second swing cover 22 does not need to be the width size of the carton body 1, which can save materials and costs.

[0051] In one embodiment, the buckling structure includes a locking tongue 23 and a locking groove 24 that cooperate with each other. The locking tongue 23 and the locking groove 24 are respectively arranged at the buckling edges of the two first swing covers 21 .

[0052] The locking tongue 23 and the locking groove 24 are used. When the first swing cover 21 is buckled, the locking tongue 23 of one first swing cover 21 and the locking groove 24 of the other first swing cover 21 are plugged and matched to achieve self-locking. The buckling edge of one first swing cover 21 can be provided with all locking tongues 23, or all locking grooves 24, or the locking tongues 23 and the locking grooves 24 can be mixed, for example, the locking tongues 23 and the locking grooves 24 are alternately provided.

[0053] In one embodiment, the opening of the lock slot 24 is set towards the lock tongue 23, and the opening width of the lock slot 24 is smaller than the maximum width in the slot, the root width of the lock tongue 23 matches the opening width of the lock slot 24, and the lock tongue 23 matches the inside of the lock slot 24.

[0054] Since the opening width of the lock slot 24 is smaller than the maximum width in the slot, and the lock tongue 23 matches it, the root width of the lock tongue 23 matches the opening width of the lock slot 24, so that the lock tongue 23 and the lock slot 24 can be plugged in the depth direction of the lock slot 24, and along the extension direction of the lock slot 24, the lock tongue 23 and the lock slot 24 are self-locking and difficult to separate. The shape of the lock tongue 23 and the lock slot 24 is not limited to the circle shown in the figure.
