Description

Improved carton structure

The utility model belongs to packaging and relates to a packaging carton.

Existing a kind of carton that is close to cube is as shown in Figure 4 and Figure 5, and its structure is respectively connected with a triangular box cover 21 at the both sides bottom surface edges of a square box body 20, and this triangular box cover 21 It is folded by a piece of paper, as shown in Figure 5, the process will not be described, but the situation before and after folding shown in the figure is enough to know its complexity, so that the box cover 21 is folded in half into a double-layer state, and the edge is folded. Connect to both sides of the bottom surface of the square box body, and then stick a piece of square paper 22 to the bottom surface of the box body 20. In this way, a box will be made with four sheets of paper of different sizes, which is quite a waste of manufacturing time and cost, and This kind of packaging box is thrown away after use, which is also quite a waste of materials.

The purpose of this utility model is to provide an improved carton structure, so that it has the concept of environmental protection. With the most economical piece of paper, it can be formed into a box with the same effect as the existing box as long as it is folded according to the folding line. , which can simultaneously contain the structure of a square box body and a triangular box cover on both sides.

The utility model that achieves the above-mentioned purpose has a central bottom surface, and the upper and lower sides of the bottom surface are respectively adjacent to a long side part. The long side of each long side part is connected with an inwardly folded part, and the two short sides of the inwardly folded part are respectively connected with a Pulling part, each side of the pulling part is provided with a seam that is engaged with the opposite pulling part to form the inside of both sides; the left and right sides of the bottom face are adjacent to a short side part, and the short side parts The long side is connected with a cover face, and the upper and lower sides of the cover face are respectively adjacent to a triangular side part. The short side faces correspond to each other, so you can see the box part when you open the two covers.

The main effect of the utility model is that a piece of paper can be folded into a square box-shaped main part in the middle, and the main part is a double-layer side structure, which is quite strong. The short side is connected with the cover and the triangular side to form a triangular box cover, which shows a different effect from the previous ones. Therefore, the overall production is quite convenient, it is easy to fold, and it is also very convenient to disassemble. . Seen from this, the utility model also meets the requirement of environmental protection very much.

Embodiments of the utility model are shown in the accompanying drawings.

Each label in above-mentioned accompanying drawing represents:

11-bottom face, 12-long side face, 13-inward fold, 14-tracting part, 141, 142-seam, 15-short side face, 16-lid face, 17-triangular side face, 18-triangular block ,

20-square box body, 21-triangular box cover, 22-square paper.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

The utility model is shown in Fig. 1, Fig. 2 and Fig. 3, and the whole is punched out from a piece of paper and then folded according to the folding line. The long sides 12, the long sides of each long side 12 are connected with an inwardly folded portion 13, the two short sides of the inwardly folded portion 13 are respectively connected with a pulling portion 14, and a seam 141, 142 is respectively opened on both sides of the pulling portion 14 , so that the pulling part on the upper side is engaged with the pulling part on the opposite side to form the interior of both sides; the left and right sides of the bottom surface 11 are adjacent to a short side part 15, and each short side part 15 The long sides are respectively connected with a cover face 16, and the upper and lower sides of the cover face 16 are respectively adjacent to a triangular side part 17. 18, each triangular block 18 is bonded to the corresponding position of the short side part 15 inner surface, so as shown in Figure 3, open the two cover faces 16 and you can see the main part folded into a square box shape.

Claims (1)

1, a kind of carton structure improvement with a center bottom face, it is characterized in that: bottom surface sections is each adjacency one long side surface portion of both sides up and down, the long edge joint of this each long side surface portion has an inflexed part, two minor faces of inflexed part respectively are connected to the portion of making a match, and the portion both sides of making a match respectively offer and make the seam that closes of clamping mutually with the portion of making a match of subtend together; Bottom surface sections is each side in abutting connection with a short side surface part, the long edge joint of this each short side surface part has a capping portion, each adjacency of the both sides up and down of capping portion has a triangle side portion, this triangle side portion is outer little interior big triangle, minor face in each triangular sides portion is connected to a corner block, and this corner block is bonded in short side surface part corresponding section.
