Description

box structure

This creation is related to the box structure, especially a box structure that effectively prevents the liquid inside the box from seeping from the side edges.

Press, there are different opinions about the history of boxes. According to historical records, the first person in the world to develop mass-produced cartons was Robert Gale from Scotland. He used cardboard bending to produce the first box around 1890 AD. For cartons, it was also discovered that paper shapes of predetermined shapes can be pre-cut by machine and then folded into cartons. This discovery was the predecessor of the modern carton die, which effectively solved the problem of mass production, and also led to the large-scale application and manufacturing of cartons and cartons in the 20th century.

In this embodiment, the open end 41 is generally arc-shaped.

The box body is formed by first bending the two first inner panels 21 of the two first side panels 20 in a direction close to each other along the two first fold lines 11, and then bending the two first side panels 20. The first outer panels 22 are bent in directions away from each other along the first side fold line 23, so that the two first outer panels 22 are respectively located outside the two first inner panels 21, and the two first inner panels 21 are in contact with the first inner panels 21. Two interlayers are formed between the two first outer panels 22 . Then, the two second inner panels 31 of the two second side panels 30 are bent in a direction close to each other along the two second fold lines 12, and then the two second outer panels 32 of the two second side panels 30 are folded along the two second fold lines 12. The two second side fold lines 34 are bent in directions away from each other, so that the two second outer panels 32 are respectively located outside the two second inner panels 31 . Then, the two tabs 33 of each second side panel 30 are bent inward along the fold lines 35 of the two tabs, and the two tabs 33 are inserted into the two sandwich layers to form a fixed state, thereby completing the box structure. Quick assembly.

When the two first side plates 20 and the two second side plates 30 are bent relative to the bottom plate 10 , the leakage prevention portions 40 will also be bent relative to the bottom plate 10 . At this time, the open end 41 of the leakage prevention portion 40 is separated from the bottom plate 10 by a predetermined distance, so that the vertical height of the leakage prevention portion 40 is higher than the vertical height of the bottom plate 10 . Since the leakage prevention part 40 is integrally formed on the bottom plate 10 , the gap between the first side plate 20 and the second side plate 30 extends from the open end 41 of the leakage prevention part 40 , and is not as clear as conventional paper. The container is connected directly to the base plate. Thereby, when the box is used to hold food, the soup will be blocked by the leak-proof portion 40 and will not leak out along the gap between the first side plate 20 and the second side plate 30 , effectively solving the problem of using conventional paper container structures. It is easy to cause liquid leakage problems.

Please refer to Figure 3. This creation can also be applied to rectangular container structures. The figure shows the box structure provided by the second preferred embodiment of the present invention, and its structure is similar to that of the first preferred embodiment. However, the base plate 10 has a rectangular structure, so the lengths of the first side plate 20 and the second side plate 30 are different. No matter how the length ratio of the first side plate 20 and the second side plate 30 is changed, the leakage prevention part 40 can achieve the same leakage prevention effect.

To sum up, the box structure provided by this invention uses the structural design of the leak-proof parts to fill the gap at the bottom of the first side plate and the second side plate, so that the liquid inside the box can It will be blocked by the leakage-proof part and will not leak out from between the first side plate and the second side plate, effectively solving the problem of liquid leakage in the use of conventional paper container structures.
