Description

Technical Field

[0001] The present invention relates to the technical field of packaging boxes, in particular to a packaging box lining. Background Art

[0002] With the wide promotion of 5G, the smart operation and smart home markets have entered a stage of rapid development. As one of the supporting equipment, the smart faucet needs to take cost control as the main consideration when designing the packaging box. In addition, due to the increasing environmental protection control year by year, the price of packaging materials continues to increase. Therefore, in addition to considering safety, stability, neatness, beauty, and convenience for users, the packaging design of the smart faucet also has low cost as the main design purpose.

[0003] As a new type of smart electronic product, smart faucets have many accessories. Usually, the packaging boxes of such products are made of EVA (EVA refers to "ethylene-vinyl acetate copolymer" and its rubber-plastic foam material), EPE (pearl cotton) and other cushioning materials. While protecting the product, an independent accessory packaging box is designed, and the accessory box and product packaging box are integrated into a color box. The above design is a commonly used packaging method in the market, but it cannot meet the demand for the purpose of reducing costs. The reasons are as follows:

[0004] 1. It is our common practice to pack all accessories separately in accessory boxes and then put them into color boxes. The main body placement area is designed on the EVA tray. This method can meet the protection requirements and will not affect the appearance. However, due to the large size of the product, the amount of packaging materials used is large, there are many accessories, and the workload of workers increases, resulting in high costs;

[0005] Second: If the design is based on the scheme of ordinary faucets on the market, the accessories will be put into PE (polyethylene) bags or bubble bags with good cushioning effects, and placed directly in the empty area of ​​the color box. The accessories are put into bubble bags or foam bags and put into the color box. Although this packaging method saves costs, it has high safety risks and affects the customer's perception of the product after opening the box, resulting in a poor experience.
