Abstract
This paper deals with a design of beverage can ends (lids) with better finger access. The process of a finger lifting the tab of SOT (Stay-On-Tab) ends is simulated using finite element method, and the sensation of a pain at the fingertip is quantitatively evaluated by the maximum value of the contact normal stress. The smaller the contact stress is, the less pain the finger is experienced and the better the finger access of the tab is. Three tab models with different shape at the finger access part were analyzed and the finger access characteristics were compared. The conclusion is that the tab with the shape that can hve a larger contact area with the fingertip during the process of being lifted up has better finger access.
