Although the traditional packaging is good for sealing,such as paint buckets or food cans,it is hard to be opened, especially for some women, the old and the young, and those who have long fingernails.They have to open them with the help of other objects to avoid getting hurt but it is not convenient enough.In order to solve this problem, we add a lunula lid to the top of the jar, so that it can be easier to be opened.It can also save labor as well as materials,and protect women who have long fingernails.
