Description

Packing box and foldable sheet

The present invention relates to a package, and more particularly to a package having a corner structure reinforced and a foldable sheet for folding to form a package.

Typically, cartons are generally folded from a piece of cardboard, which typically includes a glued surrounding wall and a plurality of panels extending outwardly from the surrounding wall, the extended panels being relatively folded to enclose the surrounding wall. If you want to strengthen the strength of the carton, it is usually achieved by thickening the cardboard. However, in practice, the carton usually only has a partial structure to be strengthened, such as a corner structure. In the foregoing manner, the overall structure of the carton is strengthened, and the part that has no structural reinforcement requirement is also strengthened, resulting in a certain amount of waste of resources. If an additional accessory is placed in the corner to reinforce the structure of the corner, the manufacturing and assembly costs of the additional accessory are increased. Moreover, the additional fitting is simply placed in the corner, and has no structural connection with the carton surrounding wall, so the added structural strengthening effect is limited.

In view of the problems in the prior art, the present invention provides a package that utilizes corner reinforcements that are coupled to the cabinet structure to reinforce the corner structure of the cabinet to provide protection of the angular structure of the contents contained therein.

The first side wall includes a first outer wall portion and a first inner wall portion that are connected to each other. The upper cover is engaged with the box to close the accommodating space. The corner reinforcement member is disposed at the first corner and includes a corner bottom plate, a first corner side plate and a second corner side plate. The corner bottom plate is disposed on the bottom, the first corner side plate is connected to the corner bottom plate, and the second The corner side plate is sandwiched between the first outer wall portion and the first inner wall portion and connected to the first corner side plate or the corner bottom plate. Wherein, if the second corner side panel is connected to the first corner side panel, the corner bottom panel is connected to the first sidewall, and if the second corner side panel is connected to the corner bottom panel, the first corner side panel is connected to the first One side wall. Thereby, the corner reinforcement strengthens the structure of the package at the corner, and the corner reinforcement has a structural direct connection relationship with the first sidewall, so that the angle reinforcement and the first sidewall are mutually produced. The strong structural combination further enhances the reinforcing effect of the structure of the package at the corner.

Another object of the present invention is to provide a foldable sheet for folding to form a package.
