Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a packaging box having at least two storage box parts.

Conventionally, a packaging box equipped with a plurality of storage parts has a double intermediate wall having a connecting part at the upper end, a bottom wall extending from the intermediate wall in opposite directions, and a double intermediate wall having a connecting part at the upper end, and a bottom wall extending from one side of the bottom wall in opposite directions. a side wall facing the intermediate wall; a side wall provided at both ends of each bottom wall; and an inner wall connected to each side wall via the top wall;
A folding piece provided point-symmetrically at one end of the intermediate wall and having a part folded in the opposite direction from the middle located in the middle of the side of the case, a folding piece provided at the other end of each intermediate wall, and both ends of each side wall. There was one that consisted of a fold-out piece attached to the top.

However, in this type of product, the folding piece that is folded in the opposite direction simply folds back the middle part and simply crosses a part of it to the other side, so the folding piece provided at both ends of the side wall is not a folding piece. It is necessary to securely connect it to the folding piece provided on the intermediate wall, which causes inconvenience during assembly.Also, since the piece that crosses the border is not connected to the other pieces, the left and right cases will wobble, and furthermore, When stacked in multiple tiers during use, the two-tiered boxes are locked by the hook-shaped protruding pieces provided at the corners of the edges, and the bottom part is prevented from coming off, so the boxes are packaged individually. In addition, judging from the unfolded state for other packaging applications, the overall construction area increases and the use of high-cost cardboard etc. reduces material costs. It is bulky, and when assembled, it takes time and effort to attach folding partition pieces of a different configuration, and when a user such as a farmer assembles and uses a large number of them, it takes time and effort to assemble, making it inconvenient to use. Furthermore, the folded partition pieces tend to move blindly, making it impossible to store fruits and the like in a stable manner.
