Technical Field

[0001] The utility model relates to the technical field of packaging cartons, in particular to a folding carton. Background Art

[0002] Paper boxes (cartons) are widely used in our lives due to their portability and easy processing. People usually make cartons in various sizes and shapes to hold and transport different items, such as screen packaging boxes, shoe boxes, etc.

[0003] After retrieval, Chinese Patent Publication No. CN212738868U discloses a folding carton. The key points of its technical solution are as follows: It includes a box body. The box body has a rectangular box bottom. Four box boards are arranged on the periphery of the box bottom. Two first folding slashes are arranged on each of the two relatively arranged box boards. First support plates are arranged at both ends of the other two relatively arranged box boards. The four first support plates are all arranged inside the corresponding box boards and are partially adhered to the corresponding box boards. The adhered part is arranged outside the first folding slash. The utility model has the following beneficial effects: When storing, fold the box body, and fold the box boards inward to save space as much as possible. When using, unfold the box boards outward, and the first support plates support to keep the structure stable, improve the strength of the box body, and it is not easy to deform when in use.

[0004] However, in the above technical solution, only the box boards are unfolded to form the box body, and the folding is carried out by moving two box boards towards each other. However, after the box boards are unfolded to form the box body, when an external force impacts the two box boards with folding lines, the box boards will fold, and the box cover and the box boards will separate from each other and lose the protection ability for items. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a folding carton aiming at the problems existing in the background art.

[0006] The technical solution of the utility model: A folding carton includes a box body, and a box cover is slidably connected above it. Both the box body and the box cover are rectangular.

[0007] The box body includes a bottom board, and baffles are connected to both ends of the bottom board. Folding lines are opened on the baffles; there are two symmetrically arranged side walls, and the side walls are adhered to the bottom board. Connecting plates are connected to both ends of the side walls close to the baffles, and the connecting plates are adhered to the baffles.

[0008] The box cover includes a fixing plate, and rotating plates symmetrically arranged are used to be connected to both ends of the fixing plate. A through installation groove is opened in the rotating plates; installation plates are connected to the other two ends of the fixing plate. Arc-shaped blocks are connected to both ends of the installation plates, and the arc-shaped blocks are slidably connected to the installation grooves.

[0009] The fixing plate is divided into an inner plate and an outer plate, the inner plate and the outer plate are adhesively bonded to each other, and a plurality of symmetrically arranged fan-shaped grooves are formed in the inner plate of the fixing plate, and a fan-shaped limiting plate is connected in the fan-shaped groove.

[0010] Preferably, accommodating grooves are symmetrically arranged on both the box body and the box cover, and a pulling plate is connected in the accommodating groove.

[0011] Preferably, the box cover and the box body are set to be of the same height.

[0012] Preferably, the length and width of the inner wall of the box cover are both greater than the length and width of the outer wall of the box body.

[0013] Preferably, the folding lines on the baffle and the connecting plate are both at degrees.

[0014] Compared with the prior art, the above technical solutions of the present utility model have the following beneficial technical effects:

[0015] In the present utility model, both the box body and the box cover can be folded to reduce the space occupied during transportation. When the folding of the box cover is completed, none of the side walls of the box cover have folding lines, thereby improving the overall strength of the box cover and avoiding the problem that the side walls of the box cover are easily deformed when subjected to external forces. When the box cover and the box body are matched, the limiting plate on the box cover will contact the side wall of the box body, and the limiting plate will limit the bending of the box body along its own folding line. The limiting plate and the side wall of the box cover limit both sides of the side wall of the box body to prevent it from being deformed individually when subjected to external force impact and disengaging from the connection with the box cover.

[0026] Embodiment Two

[0027] As Figures 2-5 shown, a folding paper box proposed by the present utility model. Compared with Embodiment One, the detailed structures of the box body 1 and the box cover 2 are described in this embodiment. The box body 1 includes a bottom plate 3, a baffle 4, a wall plate 5 and a connecting plate 6. Both ends of the bottom plate 3 are connected to the baffle 4. A folding line is provided on the baffle 4. The connecting section of the bottom plate 3 is used to connect the wall plate 5. Both ends of the wall plate 5 are used to connect the connecting plate 6. A folding line coinciding with the folding line on the baffle 4 is provided on the connecting plate 6;

[0028] In an alternative embodiment, the folding lines on the baffle 4 and the connecting plate 6 are both 45 degrees;

[0029] The box cover 2 includes a fixing plate 7, a rotating plate 8, a mounting plate 10 and an arc-shaped block 11. Both ends of the fixing plate 7 are used to connect the rotating plate 8. When in use, the rotating plate 8 is set at a right angle to the fixing plate 7. A through mounting groove 9 is provided in the length direction of the rotating plate 8 itself. The other two ends of the fixing plate 7 are used to connect the mounting plate 10. The arc-shaped block 11 is connected to both ends of the mounting plate 10. The arc-shaped block 11 is slidably connected to the mounting groove 9;

[0030] In an alternative embodiment, symmetrically arranged receiving grooves 16 are provided on both the box body 1 and the box cover 2. A pulling plate 17 is used to be connected inside the receiving grooves 16; the pulling plate 17 can gradually rotate to be perpendicular to the box body 1 and the box cover 2. At this time, the pulling plate 17 functions as a handle to facilitate the user to separate the box body 1 and the box cover 2.

[0031] Embodiment Three

[0032] As Figures 3-5As shown in the figure, a folding carton proposed by the present utility model. Compared with the second embodiment, the detailed structure of the fixing plate 7 is described in this embodiment. The fixing plate 7 is divided into an inner plate 12 and an outer plate 13. The inner plate 12 and the outer plate 13 are adhesively bonded to each other. A plurality of symmetrically arranged sector-shaped grooves 14 are provided in the inner plate 12 of the fixing plate 7, and a sector-shaped limiting plate 15 is connected in the sector-shaped groove 14. In the use state, the limiting plate 15 rotates out from the sector-shaped groove 14, and the limiting plate 15 is perpendicular to the inner plate 12. In the initial state, the limiting plate 15 is in the sector-shaped groove 14 and parallel to the inner plate 12, which facilitates the storage of the fixing plate 7.

[0033] In summary, when the present utility model is in use, the staff bends the baffles 4 at both ends of the bottom plate 3 so that they form a right angle with the bottom plate 3, and then bends the wall plates 5 so that they form a rectangular frame with the baffles 4. The connecting plates 6 at both ends of the wall plates 5 and the baffles 4 are adhesively bonded by an adhesive. The folding lines on the baffles 4 and the connecting plates 6 coincide with each other. At this time, the folding of the box body 1 is completed. If transportation is required, press the wall plates 5 so that the connecting plates 6 at both ends drive the baffles 4 to bend to reduce the occupied space of the box body 1. When folding the box cover 2, first bend the rotating plate 8 so that the rotating plate 8 is perpendicular to the fixing plate 7, and then bend the mounting plate 10 so that it is also perpendicular to the fixing plate 7. During the bending process of the mounting plate 10, gradually insert the arc-shaped block 11 into the mounting grooves 9 provided at both ends of the rotating plate 8, and limit the position of the arc-shaped block 11 by the friction force between the papers. After folding, the box cover 2 can withstand a large external force without deformation. When using the box body 1 and the box cover 2, the staff bends the limiting plate 15 with a tool so that it is parallel to the mounting plate 10. At this time, the gap between the limiting plate 15 and the inner wall of the box cover 2 is used to accommodate the side wall of the box body 1. At the same time, the folding line position of the connecting plate 6 and the baffle 4 will contact the limiting plate 15, and the limiting plate 15 limits the bending of the baffle 4 and the connecting plate 6, preventing them from being deformed by external impact in the use state and unable to protect the object.
