Description

Reusable cardboard box

technical field

The utility model belongs to a container for article storage and packaging, in particular to a polygonal cardboard folding packaging box with a device for preventing illegal opening.

Background technique

The packaging carton folded by polygonal cardboard is the most commonly used package for packaging small items. It has the advantages of low price, convenient use, and environmental protection. Pull the movable surface to pull out the tongue, and the box body can be opened to take out the items in the packaging box. This structure can be reused, and the items in the box can be easily replaced by unscrupulous businessmen. ZL00236967 discloses a kind of outer packing that is suitable as wine or other bottled beverages. The inner side of the box body of this kind of packaging box is provided with cardboard for fixing the bottleneck, the box cover is provided with tearing and indentation tooth holes, and a large lock tongue is set in the middle of the edge of the box cover, and there is a small lock tongue on both sides of the big lock tongue. , a lock hole matched with the lock tongue is also arranged on the fixed cardboard, and a lock tongue is respectively arranged on both sides of the edge of the box cover. It is realized that it is impossible to take out the actual contents of the box without destroying the box, thereby effectively preventing the box from being reused. However, this structure is only suitable for bottled items, and it is inconvenient to use for ordinary products.

Utility model content

The purpose of the utility model is to provide a new type of cardboard packaging box that is suitable for various items that can be packaged in a rectangular parallelepiped box to prevent repeated use.

The technical scheme of the utility model is, a cardboard packaging box for preventing repeated use, including a box body, a movable surface, and a protruding tongue. The dead bolt hole is provided with a dead bolt on the fixed surface overlapping with the extended tongue.

The deadbolt includes a rectangular tongue base and a trapezoidal tongue tip, and the length of the long side of the trapezoidal tongue tip bordering the tongue base is 5-10mm longer than the length of the deadbolt hole.

There are two tearing and indentation perforation lines in the shape of a figure-eight on the fixed surface of the box body.

The two sides of the tongue root of the lock tongue are separated from the fixed surface, and the boundary line between the bottom of the tongue root and the fixed surface, and the boundary line between the tongue root and the tongue tip are tearing and indentation perforation lines.

When the cardboard packaging box for preventing reuse disclosed by the utility model is in use, after the packaged items are put into the box, the protruding tongue connected with the movable surface is inserted into the box body, and then the set tongue tip is inserted into the bolt hole. The long side of the trapezoidal tongue tip is 5-10mm longer than the length of the tongue hole. After the tongue tip enters the lock tongue hole, it cannot exit. The connection with the base of the tongue will be broken, and the packaging box will be destroyed to prevent reuse. Opening the eight-shaped tearing and indentation perforation line on the fixed surface can quickly open the package and also destroy the box body to prevent repeated use.
