Description

Technical Field

[0001] The utility model relates to the technical field of improved design of carton packaging structures, in particular to a building block type buffer paper-plastic packaging for a display. Background Technique

[0002] The packaging of liquid crystal displays is mainly composed of a carton and a buffer pad, and its main function is to protect the liquid crystal display from being damaged by excessive impact, and the buffer pad plays a major role. Currently, the commonly used buffer materials are expanded poly(styrene) (EPE) and expanded poly(ethylene) (EPS). However, with the introduction of the "plastic limit order", paper packaging has become an alternative to plastic due to many advantages.

[0003] Nowadays, pulp molding packaging has become one of the most innovative ecosystems. While achieving the EU Green Deal, it can also help promote the health and safety of global consumers and play a huge role. The pulp molding industry has also undergone rapid changes, with the production scale constantly expanding and the technical level constantly improving. Most of the existing pulp molding buffer packaging for displays on the market is integral or composite, which means that the volume and weight of the packaging are relatively large, and the material cost and warehousing and transportation costs will be relatively high, increasing the overall packaging cost. At the same time, conventional paper-plastic packaging is only suitable for the packaging of pizza boxes with narrow sides, and has limitations on the structure of the outer packaging box.

[0004] In the prior art, the patent with the publication number of CN220363668U discloses a paper-plastic for the packaging of a display, including: a packaging box, a first paper-plastic bracket filled in the packaging box, a second paper-plastic bracket, a third paper-plastic bracket, a display screen, a connecting plate, a bracket, the first paper-plastic bracket forms a first upper and lower surface, a support block protrudes from the first upper surface, and a plug-in groove is provided between the support blocks; the second paper-plastic bracket forms a second upper and lower surface, a handle groove is provided on the second upper surface; a first display screen fixing groove for the front surface of the display screen to be embedded is recessed on the second upper surface, and a second display screen fixing groove is provided near the handle groove; carton grooves are provided on the two short sides of the second upper surface; a support plate is provided on the second lower surface, and a reinforcing rib is recessed on the support plate; the utility model makes the packaging structure of the display screen more reasonable, can make full use of the buffer space in the packaging box, and can better protect the screen of the display screen and the accessories of the display screen.

[0005] In the above technical solution, the paper-plastic bracket is designed in an integral structure. For packaging paper-plastics of the same size specification, it can meet the requirements of mass production. However, for packaging paper-plastics with different size specifications, the integral design often requires multiple sets of different molds, resulting in high production costs and being unable to meet the requirements of small-batch flexible production.

The first paper tray 1 includes a first support portion 11. The first support portion 11 extends upward to form a first enclosing portion 13. First fastening portions 12 are respectively provided at two ends of the first support portion 11. The first fastening portions 12 are located below the corner positions of the first enclosing portion 13; a second paper tray 2. The second paper tray 2 includes a second support portion 21. The second support portion 21 extends upward to form a second enclosing portion 23. Buckling positions 22 are respectively connected to two ends of the second support portion 21; a third paper tray 3. The third paper tray 3 includes a third support portion 31. The third support portion 31 extends upward to form a third enclosing portion 37. Third fastening portions are respectively provided at two ends of the third support portion 31. The third fastening portions are located below the corner positions of the third enclosing portion 37; a fourth paper tray 4. The fourth paper tray 4 has the same structure as the second paper tray 2.
