**Creative Concept**
Drawing inspiration from "Growth Building Blocks," the children's growth nutrition product is transformed into an interactive, three-dimensional growth system. Each inner packaging is designed in the shape of a round building block, made from food-grade PP material, ensuring safety with its smooth, rounded edges. The outer packaging features a pull-out box with height scale markings, resembling a ruler. The rocket element on the building block box enhances the product's interactivity and visually represents the concept of growing taller. When multiple boxes are stacked together, they create the visual effect of a rocket ascending, symbolizing the child's growth trajectory through height. The inner box incorporates an "Easter egg" mechanism: the more blocks collected, the higher the growth rocket "flies" (which can also serve as a height recorder for the child). The four different colored building block boxes can be stacked in any combination, allowing children to understand the relationship between nutrition and height through play. Parents can record the child's growth data based on the height of the stacked blocks, transforming a functional product into a keepsake that holds precious family memories.
