Double-opening quick drinking tank

The two-port fast drinking can may combine the advantages of a standard aluminum beverage can with the second opening to allow high rate air flow and replacement to achieve high rate liquid outflow from the can. For ease of use and familiarity, the can may implement an in-line tab mechanism or any other suitable mechanism on the standard top opening, and may further implement an in-line tab mechanism or other suitable mechanism on the bottom or underside of the can for fast drinking the liquid in the can. 双口快饮罐可以将标准铝制饮料罐的优点与第二开口结合起来以允许高速率的空气流动和置换，从而实现高速率的液体从罐流出。为了易于使用和熟悉，罐可以在标准的顶开口上实施内嵌式拉环机构或任何其它适当的机构，并且可以进一步在罐的底部或下侧实施内嵌式拉环机构或其它适当的机构，用于快饮罐中的液体。
