As we all know, traditional zip-top cans have many disadvantages. For example, it should be drunk off in a short time, otherwise it could be expired. What’s worse, it could cause some pollution when we cycle them. To solve this kind of problem, we change the structure and material of the bottle, adding a windtight lid to it. In this case, the bottle could be sealed up again, protecting people from suffering from food poisoning. Moreover, the used zip-top cans could be used as cups, vases and so on. In a word, it could become recycling and could be used in various ways. A small change could make a huge difference in our daily life.
