Simple beer can replace with sliding tips

This simple beer can design makes it easier to open and use. The standard cans we see in stores often have a tendency to break at the tip, which is frustrating. Another issue with regular cans is that they don't allow for preservation of drinks over time - if you only drink half your beer before finishing it off later, the remaining liquid can go flat quickly. This new design improves upon these flaws by allowing the beer to stay pressurized for several hours longer than usual.
