Flatting Spoon / packing design

Ordinary tin of milk powder will be contained inside a small plastic spoon used to scoop from milk.
However, using the plastic spoon to spoon the milk, it is very easily scattered to the desktop, so we would normally shake the spoon or scrape the excess milk items.
In order to solve this problem, we do change in formula cans, the gap is designed to be a complete circle, so that it can be used to scrape off the excess milk.
