Description

TECHNICAL FIELD

[0001] The utility model relates to the packaging field especially, relate to a packing box. BACKGROUND

[0002] The packing box is a container commonly used in daily life, which is used for containing fruits, drinks, clothes and other target objects. The commonly used packing box is hexahedral and is formed by folding paperboard. Generally, the packing box includes four non-openable side walls and two openable side walls, and the six side walls enclose a space for containing the target objects. Among the two openable side walls, one serves as the top wall of the packing box, and the other serves as the bottom wall of the packing box. The top wall and the bottom wall each include four paperboards connected with the four side walls. When packing the target objects, the four paperboards of the bottom wall are first folded in pairs, and then the opposite edges of the outermost two paperboards are bonded by adhesive tape, so that the packing box becomes a cavity with only the top wall open. After the target objects are loaded into the space, the four paperboards of the top wall are folded and bonded in the same manner as the four paperboards of the bottom wall.

[0003] When the packing box is used for containing multiple target objects such as fruits and drinks, in the transportation process, in order to prevent the multiple target objects from moving in the packing box and causing damage to the target objects, a partition assembly is also placed in the space of the packing box. The partition assembly divides the space into multiple small spaces, and each small space is used for containing only one target object, thereby playing a role in protecting the target objects from being damaged.

[0004] However, in the packing process, the partition assembly needs to be additionally placed in the space of the packing box, which is relatively troublesome. Moreover, the partition assembly itself is not fixed in the space, and the partition assembly will also move, so the target objects will also be damaged to a certain extent.

[0005] When the packing box contains fruits with a high water content, once the bottom wall paperboard of the packing box with this structure is wet, the strength of the bottom wall will be greatly reduced, which easily causes the bottom wall paperboard to fall off and the target objects to fall out of the packing box.

[0006] On the other hand, when the user needs to take out the target objects, or after taking out the target objects, the packing box needs to be folded up for storage, a sharp instrument needs to be used to cut the adhesive tape. In this process, not only can the user be pricked by the sharp instrument, but also the adhesive tape is wasted. INVENTION CONTENTS
