a straw-hidden can body / Student

Pop-top cans are widely used in life because they are easy to be recycled, convenient to be transported and have many other advantages. But as we drink directly from the opening, it may bring health risks and adverse effect to our body. In response to this problem, a design of a straw-hidden can body is proposed. When the pull-tab being pulled up, the straw built in the can body will be brought out. After use, the straw can be hidden in the can body with the pull-tab closed. This is designed to avoid direct contact and prevent dust from entering the can.
