Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, in particular to a flip-cover packaging box. Background Art

[0002] The clamshell box is a classic design that became popular in the United States in the early 20th century. It is a box with a lid, usually with a switch inside the lid to open or close the box. The design of the clamshell box was originally designed to make it easier for people to open or close the box, but it has now become a fashion and trend. In the early 20th century, people began to use various materials to make clamshell boxes. For example, aluminum lids were used to make aluminum clamshell boxes, stainless steel lids were used to make stainless steel clamshell boxes, and glass and plastic lids were used to make plastic clamshell boxes. Most clamshell packaging boxes for products are now made of cardboard because it is cheaper and simpler to make. However, some clamshell boxes with lids connected to the box body will cause creases during use due to the influence of force. This makes it unsightly when packaging products, and such outer boxes are difficult to reuse.

[0003] Patent publication number CN2902910Y discloses a new type of foldable packaging box, which includes a cover body with four surrounding panels and an open box body. The upper edge of one side wall of the box body is connected to one side of a display board in a movable folding manner, and the other side of the display board is connected to the middle part of the inner side surface of the cover body in a movable folding manner, and the upper edges of the left and right side walls of the box body are respectively provided with positioning devices that can clamp the lower side edges of the cover body surrounding panels; in this patent, the upper cover is connected to the box body through a display board, and the folding of the upper cover is achieved by the display board, and the display board is flexible, which means that no indentation will be generated when the upper cover is folded.

[0004] However, the upper end of the display board is connected to the middle of the inner side of the upper cover, that is, the movable area of the display board is larger, which makes the range of movement of the upper cover also larger, and the force received at the connection between the display board and the upper cover will also be greater. During use, the connection between the upper cover and the display board may be disconnected, affecting the user experience. Summary of the Invention
