Abstract
Description
Technical Field
[0001] This utility model relates to a milk powder can, and more particularly to a novel milk powder can structure. Background Technology
[0002] Current infant formula cans generally use a simple one-piece or threaded lid design. The connection between the lid and the can body is not secure enough, and the lid is prone to displacement or detachment during transportation or use due to impacts, causing the formula to become damp or contaminated. At the same time, common sealing methods are not very effective in preventing moisture from the air from entering the can, affecting the freshness and quality of the formula. Furthermore, the structure of traditional formula cans makes opening and closing the lid inconvenient, resulting in a less than ideal user experience. Utility Model Content
