Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a contoured box sleeve for packaging L-shaped parts. Background Art

[0002] With the rapid growth of the aviation industry, automobile industry and light consumer goods production, the shapes of parts required are becoming more and more diverse, the precision requirements for parts are becoming higher and higher, and the parts are becoming smaller and smaller. For these diversified, flexible and complex parts, not only efficient and high-quality processing is required, but also the packaging safety during transportation is an issue that requires high attention. At present, most packaging methods use paper linings in cartons and cushioning material linings in cartons. A paper lining is set in the carton, and the parts are placed in the paper lining. Through the paper lining, the impact and collision of the parts during transportation are reduced, thereby playing a buffering role; however, the buffering performance of this packaging form is poor. In the actual transportation process, it is necessary to add cushioning materials outside the carton to ensure the transportation safety of the parts, thereby increasing the packaging cost of the parts; using this packaging form, the parts in the carton will also scatter, causing collisions between parts. A cushioning material lining is arranged inside the paper box so that the lining has good cushioning performance, thereby ensuring the transportation safety of the parts; however, the cushioning material lining in this packaging form not only has a high mold opening cost, reduces the packaging capacity, increases the packaging cost of the parts, but is also difficult to recycle, which has an adverse impact on the environment. Therefore, it is necessary to design a contoured packaging box cover in combination with the shape of the parts to solve the problems existing in the prior art that the existing packaging boxes have poor cushioning protection performance for complex-shaped parts during transportation and have high packaging costs.
