We designed a playable packaging for children's milk beverage products. We learned that after children drink beverages, beverage bottles are usually thrown into the trash can, resulting in a waste of resources. Therefore, we thought about how to reuse the discarded beverage bottles to make the bottle a children's toy. We Referring to the structure of the traditional toy tumbler, the beverage bottle is designed in the form of a tumbler, and the principle of the center of gravity is used to make the beverage bottle in a state that will never fall down. After drinking the beverage, it can be used as a toy to play. In the pattern design, we have selected three kinds of cute bear animals to correspond to the taste, namely "chocolate-panda, strawberry-polar bear, banana-brown bear", the cute animal images meet the psychological needs of children. The two ears of animals They are bottle caps and ring buckles, which can allow drinks to be hung on children's schoolbags and other items for easy portability.
