The background of this invention is improving the usability of aluminum beer and beverage cans currently manufactured with small openings. Although, this practice widely established by manufacturers and consumer as well, in my own experience, I found it using a cup rather a suitable drinking ware beside the can to drink the beer or beverage is always more pleasurable,healthy and comfortable in terms of eliminating the air in which, in most cases taken with the beer or beverage. By inventing and installing this opening device on top of aluminum beer or beverage cans will convert the can, kind or aluminum drinking cup or rather suitable drinking ware for the ocasion in which the beer or beverage inside of the can will be available for drinking in much more comfortable in terms of not lifting the head as much and without loosing the original taste of beer or beverage.
