The design and development of metal packaging products should be improved in combination with the printing and processing characteristics of the iron sheet. It is a practical way to enrich and develop the structure of the iron box. The innovation of packaging shape can play a role in rejuvenating the product, attracting the attention of consumers, and thus promoting product sales.
　　 The first step is to choose the shape object to be imitated according to the market positioning of the product sales, and then simplify and condense the shape to be imitated, not only the shape, but also the similarity,
　　 Then combine the characteristics of tinplate processing, design patterns, and content shape characteristics to carry out structural innovation. At the same time, convenience and safety should be considered to coordinate the model, content, and consumer psychology of consumers. Giving full play to the functions of packaging is the development trend of packaging design.
The hand-push food box has a rectangular box shape. The bottom of the box has a concave edge relative to the outside. The depth of the concave is the same as the height of the edge. After the bottom and the body are rolled, the structure of the lid is more complicated. The iron box The edge of the cover is rolled inward, and one end of the cover is cut off the cover body and then folded and pressed inward, and transitions with the arc of the cover body. Several positioning points are punched on the cover surface, and the hand-pushing function is realized after the cover is closed. The structure is simple and novel, and is suitable for packaging children's food. After the children have finished eating the contents, the packaging can be used as a stationery box, which conforms to the purchasing psychology of children and their parents.
The anti-counterfeiting packaging tank series of 　　 liquor is a successful example of the development of new packaging by the functional innovation method. While realizing the anti-counterfeiting function, continuously develop new structures and new shapes, realize the combination of new functions and functions of the packaging, and constantly introduce new ones, forming a series of white wine iron box packaging.
　　Multi-purpose wine can, consisting of a can body, a bottom, an inner lid and an outer lid. A small hole of about 50mm is opened in the middle of the outer cover, the edge of the small hole is rolled inward, and the edge of the outer cover is rolled outward. The inner cover is formed by stamping, punching and protruding at the small hole position of the outer cover, and after being closed, the convex position of the inner cover is flush with the top surface of the outer cover. Engrave two lines at the proper position of the can body, press a rib under the engraved line, and the distance from the lower engraved line to the rib is equal to the inner depth of the two outer lids. After opening, the anti-counterfeiting function is realized because the can body is cut off. After the can body is disconnected, the connecting part of the bottom cover and the outer cover form a new product-an ashtray. Tobacco and alcohol are the best partners. The wine can becomes an ashtray after it completes the packaging function. It is economical and practical, which effectively realizes the secondary use of the wine can, arouses consumers' desire to buy, and is conducive to product sales. The "assisting role" of the packaging is also played a role in advertising and publicity for liquor manufacturers and their products.
