[0005] In addition, since the structure of the carton needs to be Figure 1d As shown, the side wall 11 is attached to the end edge 14 before being transported to the factory. During the transportation process, the carton structure is folded in half and multi-layered into the factory. Due to a certain pressure during transportation, its four sides are stretched. The corners are subjected to different forces, so that the carton structure is easy to form a diamond shape when it is further folded and assembled, such as Figure 1e , thus affecting the appearance and neatness of the carton structure

[0032] First embodiment: In this embodiment, Figure 2a , 2b, 2c, 2d show the carton structure of the present invention. 2a The carton includes a side wall portion 21 and two cover portions 22a, 22b. The structure of the side wall portion 21 is the same as known ones, and its detailed description is omitted here. Through the edge connecting portion 24 located on the side wall portion, it can be assembled from the original unfolded state to see the state enclosing a space.

[0033] In detail, the unfolded carton structure is as follows Figure 2a As shown, each cover portion 22 is connected to the side wall portion 21 respectively, each cover portion 22 includes two inner covers 22a and two outer covers 22b, and each inner cover 22a is respectively connected to the side wall portion 21 to form two grooves 26, each The end edge of the outer cover 22a has two protruding parts 23 respectively, and each protruding part 23 is inserted into the corresponding groove part 26, as Fi...

[0037] Second embodiment: image 3 A second embodiment of the carton structure of the present invention is shown. In this embodiment, the carton structure includes a side wall portion 31 , two cover portions 32 and a bottom portion 34 .

[0038] The difference between this embodiment and the first embodiment is that only the upper cover 32 is provided with convex parts and grooves, while the structure of the cover at the bottom is the same as the known ones. For the convenience of description, in this embodiment In an example, the cover part located in the bottom surface is called a bottom part.

[0039] In detail, when assembling the carton structure of this embodiment, first assemble the side wall 31 and the bottom 34 in the same known manner, and then insert the convex portion 33 of the upper cover portion 32 into the groove 36 of the inner cover. Complete assembly.

Abstract

The invention relates to a one-time forming carton structure, which includes a side wall and two covers, which are respectively connected to the side walls, the inner cover is connected to the side wall as a first joint, and at least one outer cover is formed on the inner cover. convex part; the outer cover is connected to the side wall part as a second joint part, and at least one groove corresponding to the outer convex part is formed on the outer cover part, and the connection by inserting the outer convex part into the groove; the carton structure of the present invention determines The length of the first side and the second side of the cover are equal to the length of the first side and the second side of the side wall to ensure that the size of the carton installation is consistent, and after connecting the side wall to the connecting part, The deformation of the carton structure during transportation is reduced to ensure the appearance and neatness of the carton structure. In addition, the structure of the carton is simple and the cost is saved.

Description

technical field [0001] The invention relates to a carton structure, in particular to a one-time forming carton structure. Background technique [0002] The known carton structure 1a is as shown in the figure. The carton structure 1a has a side wall 11, an outer cover 12a, and an inner cover 12b, wherein the side wall 11 can be combined from the original unfolded state to be surrounded by it through the connecting portion 14 at the end edge. state of a space. [0003] The outer and inner covers 12a, 12b are folded along the creasing line 15 as shown in the figure to achieve a beautiful carton structure. It should be noted that Figure 1b It is an enlarged view of the internal structure in B, which shows that the corrugated 17 inside the carton structure is parallel to the direction of the corrugated 17 inside the carton structure with the correct crimping line 15 . [0004] However, it cannot be guaranteed that the position of the crimping line 15 is just parallel to the co...
