<p>PROBLEM TO BE SOLVED: To provide a can container provided with an additional discharge port for substantially reducing the residue in a can container because the structure of conventional can containers including the position and structure of a discharge port makes complete use of the contents, especially the oil type, difficult.SOLUTION: A can container is a double-discharge-port one provided with a discharge port 1 in the upper surface of the can container and a discharge port 2 in a diagonal corner of the can container. The additional discharge port arranged in the diagonal corner of the can container serves as both a discharge port and an air hole, resulting in two discharge ports provided. The provision of the hole, or the discharge port 2, serving as both a discharge port and an air hole in the diagonal corner to the main discharge port allows smooth draining of liquid. Residual liquid left in the bottom of the can container can be drained from the discharge port 2, resulting in substantial reduction of the residue and improvement of energy efficiency. The can container is thus environment-friendly and contributes to reduction of carbon dioxide amount.</p> |
