AI Technical Summary
The printing paper joints of existing flip boxes are prone to deformation and cracking during the flipping process, affecting the appearance and providing insufficient support strength, especially after repeated use.
By attaching printed paper to the outside of the first sidewall of the upper cover and attaching cardboard strips to the printed paper, a folded structure is formed to enhance the support strength and reduce the deformation area.
The support strength at the connection between the upper flap and the bottom box has been enhanced, reducing the deformation of the printed paper and maintaining the smoothness and aesthetics of the flap.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flip-top box technology, and specifically to a flip-top box. Background Technology
[0002] Flip-top boxes, also known as "top and bottom boxes," are packaging boxes where a top flap closes onto the bottom box for packaging. Currently, the connection between the top flap and the bottom box is achieved using printed paper. However, this paper lacks sufficient strength, and when the top flap is opened, the paper at the connection point is easily deformed by the weight of the top flap, affecting the smoothness of the opening. For high-end products, this can subtly lower the perceived quality and even cause consumer dissatisfaction. Furthermore, repeated opening and closing can cause the printed paper at the connection point to crack, resulting in an unsightly appearance and the loss of the original folding function. Therefore, we propose a new type of flip-top box. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a flip-top box to solve the aforementioned problems. By providing a first side wall, printed paper, and cardboard strips, the folded printed paper wraps around the cardboard strips and connects to the first side wall through the printed paper. The printed paper wrapping the cardboard strips can enhance the support strength of the upper flap during the flipping process and reduce the deformation area of the printed paper at the connection between the upper flap and the bottom box.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A flip-top box includes an upper flap and a bottom box. One side of the upper flap has a folded edge structure and is glued to one side of the bottom box to form a flip-top opening and closing mechanism. The folded edge structure includes a first sidewall, and printed paper is glued to the outside of the first sidewall. The printed paper extends outward to cover the excess portion beyond the first sidewall.
[0008] Preferably, a strip of cardboard is adhered to the excess portion of the printed paper, and a bending gap is reserved between the cardboard strip and the first sidewall.
[0009] Preferably, the reserved width of the remaining surplus portion of the printing paper is the width of two strips of cardboard.
[0010] Preferably, the remaining excess portion of the printing paper is coated with adhesive.
[0011] Preferably, the other three sides of the upper flap are folded to form sidewalls, and printed paper is applied to the outer and inner surfaces of the upper flap.
[0012] Preferably, both the upper cover and the bottom box are rectangular boxes.
[0013] (III) Beneficial Effects
[0014] This utility model embodiment provides a flip-top box. It has the following beneficial effects:
[0015] By setting a first sidewall, printed paper, and cardboard strips, the folded printed paper wraps around the cardboard strips and connects to the first sidewall through the printed paper. The printed paper wrapping the cardboard strips can enhance the support strength of the upper flap during the flap-opening process and reduce the deformation area of the printed paper at the connection between the upper flap and the bottom box.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] See attached document Figure 1-7 A flip-top box includes an upper flap 1 and a bottom box. One side of the upper flap 1 has a folded edge structure 2 and is glued to one side of the bottom box to form a flip-top opening and closing mechanism.
[0028] The folded structure 2 includes a first sidewall 2.1, which is formed by folding one end of the top cover cardboard of the upper flap 1. It can be understood that the first sidewall 2.1 is a fold of one end of the whole cardboard. Printed paper 2.2 is glued to the outside of the first sidewall 2.1, and the printed paper 2.2 extends outward to cover the excess portion outside the first sidewall 2.1.
[0029] A piece of cardboard strip 2.3 is glued to the excess portion of the printing paper 2.2, and a bending gap is reserved between the cardboard strip 2.3 and the first side wall 2.1 to prevent the cardboard side wall and the first side wall 2.1 from mutually restricting each other during the bending process;
[0030] The printing paper 2.2 extends along both ends of the first sidewall 2.1 to form the length direction of the printing paper 2.2. It can be understood that the printing paper 2.2 extends perpendicularly to both ends along its length direction to form the width direction of the printing paper 2.2.
[0031] The reserved width of the remaining surplus portion of the printing paper 2.2 is the width of two cardboard strips 2.3.
[0032] When using, please refer to the appendix. Figure 2 and 3 First, place the excess portion of the printing paper 2.2 in an approximately horizontal position. Next, fold the gap between the first sidewall 2.1 and the cardboard strip 2.3, and then attach the outer wall of the excess portion of the printing paper 2.2 to the outside of the first sidewall 2.1. Then, refer to the attached... Figure 4-6 The remaining excess portion of the printing paper 2.2 is folded upwards along the side wall of the cardboard strip 2.3 and adhered to the cardboard strip 2.3 (understandably, the remaining excess portion of the printing paper 2.2 is also coated with adhesive). Then, the end of the remaining excess portion of the printing paper 2.2 is folded into the upper flap 1 and adhered to and bonded to the inner wall of the first side wall 2.1. Simultaneously, the attached... Figure 6 Smooth the horizontal surface at point C back and forth, and finally refer to the attached document. Figure 7The cardboard strip 2.3 of the first sidewall 2.1, which was originally attached, is folded upward to form a complete folded edge structure 2.
