Description

Packaging carton without connectors

Technical field:

The utility model relates to the technical field of packaging cartons, in particular to a packaging carton without connectors.

Background technique:

Packaging cartons are widely used in the field of cargo packaging and transportation. At present, the more commonly used large-scale packaging cartons are generally made of corrugated paper. This kind of packaging carton has a certain thickness, has strong compression resistance, and can bear a large weight. The various parts of the existing packaging cartons are generally fixedly connected together, that is, have a certain fixed shape. The packaging box of this structure has two major disadvantages: the first is that when loading goods, it is affected by the pressure of the packaging box paper wall. impact, the goods are not convenient to put into the packing box; the second is that after unloading the goods, the packing box is inconvenient to store, if you want to fold the packing box, you need to remove the connecting parts of the packing box, which will lead to work amount increased. Therefore, it is necessary to design a packaging box with a new structure to solve the aforementioned technical problems.

Utility model content:

The purpose of the utility model is to provide a packaging carton without connectors for the deficiencies of the prior art, which has the advantages of convenient use and convenient storage, and can be reused without damaging the packaging box.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes a top cover and a bottom cover, and a carton coaming board is defined between the top cover and the bottom cover; the coaming board is composed of left and right packaging boards fastened to each other, and the left packaging board extends from the two ends of the left side board respectively to the first, The second side plate is formed, and the right packaging plate is formed by respectively extending the third and fourth side plates from the two ends of the right side plate.

The first side panel has at least two first fold lines, and the two first fold lines are parallel to each other and parallel to the connection line between the left side panel and the first side panel.

There are at least two second fold lines on the second side plate, and the two second fold lines are parallel to each other and parallel to the connecting line between the right side plate and the first side plate.

The two first folding lines divide the first side panel into three parts: left, middle and right; The structure of the two side plates is consistent with that of the first side plate.

The beneficial effect of the utility model is that it adopts the left and right packing boards to fasten each other to form a carton coaming board. When loading goods, the goods can be put into the lower cover first, and then the left and right packing boards can be inserted into the lower cover. It is fixed inside and put on the cover at the end, so the packaging is very convenient; in addition, the packaging board can be folded up, placed horizontally in the lower cover, and covered with the upper cover, which occupies a very small space and can be used for storage, and because the packing box is not damaged, Therefore, the packing box can be reused.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a structural representation of the utility model

Fig. 2 is a folding schematic diagram of the utility model

Detailed ways:

See accompanying drawing 1, the utility model comprises loam cake 10, bottom cap 20, and loam cake 10, bottom cap 20 can be square or rectangular, is limited to carton coaming between loam cake 10, bottom cover 20; The right packaging boards 30, 40 are fastened to each other, and there is no connecting piece between them, but they are close together by overlapping parts; Boards 34, 36 are formed, and the left packaging board 30 is a whole piece of cardboard, which is bent left and right to form the aforementioned structure; the right packaging board 40 is extended from the two ends of the right side board 42 to form the third and fourth side boards 44 , 46, the right packaging board 40 is a whole piece of cardboard, which is bent left and right to form the aforementioned structure.

The first side panel 34 has at least two first fold lines 342, 346, the two first fold lines 342, 346 are parallel to each other and parallel to the connecting line 340 between the left side panel 32 and the first side panel 34; The first fold line 342,346 divides the first side panel 34 into three parts: left, middle and right. The height of the cover 20 can make the folded carton more flat.

The second side plate 36 has at least two second fold lines 362, 364, the two second fold lines 362, 364 are parallel to each other and parallel to the connecting line 360 between the right side plate 42 and the first side plate 34; The two side panels 36 have the same structure as the first side panels 34; two fold lines can divide the second side panel 36 into three parts, and if there are multiple fold lines, the second side panel 36 has multiple overlapping parts after being folded.

Fig. 2 is a schematic diagram when the carton is folded. At this time, the first and second side panels 34, 36 are folded in the middle, and the left and right packaging panels 30, 40 are placed horizontally, and then they are put into the bottom cover 20 Inside, the carton of the utility model can be folded by closing the upper cover 10 at last, which takes up very little space and is convenient for storage, and since the carton is not damaged when being folded, the carton can be reused, which is environmentally friendly and reduces the packaging cost .

When packing the goods, the goods can be put into the bottom cover 20 earlier, then the left and right packing plates 30, 40 are inserted in the bottom cover 20, and finally the upper cover 10 is put on, which is very convenient to use.

Because the left and right packaging boards 30, 40 are all made of corrugated paper, they can fully play a role in packaging.

In addition, in order to make the left and right packaging plates 30, 40 can be put into the bottom cover 20, the left side plate 32 and the right side plate 42 are smaller than the bottom cover 20; the first and second side plates 34, 36 of the left packaging plate 30 Folding is to be realized, so as long as its size is satisfied without affecting the folding; the right packaging board 40 is covered on the left packaging board 30 . The 3rd, the 4th side board 44,46 inboards respectively add a piece of gray board paper, to strengthen support strength.

The utility model is very convenient for the packing of goods; in addition, the space occupied by the packing box is very small when it is closed, and it can be used for storage, and because the packing box is not damaged, the packing box can be reused.

Of course, the above-described embodiments are only preferred examples of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all equivalents done according to the structure, features and principles described in the scope of patent application for the present utility model Changes or modifications should be included in the patent scope of the utility model.
