Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically a stackable weighted carton. Background Technology

[0002] Cardboard boxes are a common packaging material used in people's daily lives and work. There are many types of these boxes. For some taller products, such as refrigerators and air conditioners, stackable cardboard boxes are used to facilitate the placement and removal of goods. However, when these stackable cardboard boxes are sealed with plastic strapping, the height makes it inconvenient to tighten the strapping. Special tools for tightening plastic strapping are required. Sometimes, it is necessary to temporarily open the box for inspection and re-tighten the strapping, but there may not be tools available.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a stacked, weighted cardboard box. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a stacked, weighted cardboard box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stacked and weighted cardboard box, comprising a box bottom and a bottomless box body, wherein the bottomless box body is stacked on the box bottom, the box bottom is composed of two layers of paper and a rigid plastic board between the two layers of paper, and packing straps are installed on both sides and the front and back sides of the box bottom.

[0006] The packing strap storage structure includes packing straps and a storage compartment installed on the outer side of the box. The storage compartment has a storage hole in the center. A roller is installed in the storage hole through a bearing. One end of the packing strap is wound on the roller, and the other end of the packing strap is connected to a connecting ridge. A round rod is connected to the bottom of the connecting ridge. A round rod insertion hole is opened in the upper part of the storage compartment. The storage hole and the round rod insertion hole are interconnected. A strip groove is opened in the top of the storage compartment. The strip groove is interconnected with the round rod insertion hole.

[0007] Furthermore, the two packing strap storage structures on the left side of the box bottom correspond one-to-one with the two packing strap storage structures on the right side, and the two packing strap storage structures on the front side of the box bottom correspond one-to-one with the two packing strap storage structures on the rear side.

[0008] Furthermore, each of the left and right sides of the box bottom has only one packing strap storage structure, which is staggered from each other; and each of the front and back sides of the box bottom also has only one packing strap storage structure, which is staggered from each other.

[0009] The lower inner part of the storage compartment is also provided with a round rod insertion hole, and a strip groove is also provided at the bottom of the storage compartment. The strip groove communicates with the round rod insertion hole, and the round rod insertion hole communicates with the storage hole.

[0010] Furthermore, the bottomless box is composed of a left half and a right half. Each half consists of a top and three sides.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution:

[0019] Please see Figure 1-4 A stackable weight-bearing cardboard box includes a box bottom and a bottomless box body, wherein the bottomless box body is stacked on the box bottom, and the box bottom is composed of two layers of paper 1 and a rigid plastic board 2 located between the two layers of paper 1, thereby increasing the load-bearing capacity of the box bottom.

[0020] The bottom of the box is equipped with a packing strap storage structure 7 on both sides and the front and back sides. The packing strap storage structure 7 includes a packing strap 71 and a storage compartment 72 installed on the outer side of the box. The storage compartment 72 has a storage hole in the middle. A roller 75 is installed in the storage hole through a bearing. In actual installation, an end plate is connected to the outside of the bearing. The end plate is fixed to the entrance of the storage hole by screws. One end of the packing strap 71 is wound around the roller 75.

[0021] The length of the packing strap 71 is pre-set according to the size of the carton.

[0022] The other end of the packing strap 71 is fixed to the connecting protrusion 78 by screws. A round rod 77 is connected to the bottom of the connecting protrusion 78. The connecting protrusion 78 and the round rod 77 are made of plastic and are injection molded as one piece. A round rod insertion hole 73 is opened in the upper part of the storage compartment 72. There is a channel between the storage hole and the round rod insertion hole 73, and the two are interconnected through the channel. The round rod 77 is inserted into the round rod insertion hole 73. A strip groove is opened on the top of the storage compartment 72. When the round rod 77 is inserted into the round rod insertion hole 73, the connecting protrusion 78 is exactly in the strip groove. The openings of the round rod insertion hole 73, the channel, and the storage hole are all on the side of the storage compartment 72.

[0023] Initially, the round bar 77 is inside the round bar insertion hole 73, and the connecting protrusion 78 is in the channel between the storage hole and the round bar insertion hole 73. When the carton needs to be sealed with packing tape 71, the round bar 77 is pulled out from the opening of the round bar insertion hole 73 and the round bar 77 is pulled gradually, so the packing tape 71 on the round roller 75 is gradually unwound.

[0024] When the two packing strap storage structures 7 on the left side of the bottom of the box correspond one-to-one with the two packing strap storage structures 7 on the right side, and the two packing strap storage structures 7 on the front side of the bottom of the box correspond one-to-one with the two packing strap storage structures 7 on the rear side; that is, the round bar 77 on the left side goes around the top of the box and is inserted into the round bar insertion hole 73 on the right storage compartment 72 to complete the packing strap tightening. Similarly, the round bar 77 on the rear side goes around the top of the box and is inserted into the round bar insertion hole 73 on the front storage compartment 72 to complete the packing strap tightening.

[0025] There is only one packing strap storage structure 7 on each of the left and right sides of the bottom of the box, and they are staggered. There is only one packing strap storage structure 7 on each of the front and back sides of the bottom of the box, and they are staggered. A round rod insertion hole 73 is also opened in the lower part of the inner part of the storage compartment 72. A strip groove is also opened at the bottom of the storage compartment 72. The strip groove communicates with the round rod insertion hole 73. The round rod insertion hole 73 communicates with the storage hole. Here, the route of the round rod 77 is an inverted U-shape.

[0026] This method differs from the above. When the round bar 77 is pulled out from the opening of the round bar insertion hole 73 and the round bar 77 is gradually pulled, the round bar 77 needs to pull the packing strap 71 through the bottom of the box, then around to the top of the box, and finally down to return to its original round bar insertion hole 73. Then the route of the round bar 77 is a rectangle.

[0027] Considering that in the current technology, when opening and closing stacked cartons, the bottom of the bottomless carton needs to be higher than the top of the goods, which makes opening and closing stacked cartons quite troublesome. Therefore, the bottomless carton is composed of a left half and a right half. Each of the left half and the right half consists of a top 4 and three sides 3. When the left half and the right half are closed, the two tops 4 are one above the other, the two sides 3 on the front of the bottomless carton are one inside and one outside, and the two sides 3 on the back of the bottomless carton are one inside and one outside.

[0028] In other words, the bottomless box is a split design. When opening the box, you only need to unfold the left and right halves in opposite directions, and close them in the opposite direction. When the two sides of the box are stacked, there is no need to fix them immediately. The bottomless box can be locked when it is sealed with packing tape.

[0029] In addition, a plastic sheet 25 is attached to one side of the bottomless box, and a cardboard layer 6 is attached to the outer wall of the plastic sheet 25. This can increase the rigidity of one side of the box, and together with the increased rigidity of the bottom of the box, it makes it easier to carry the box up stairs, etc.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
