Humor piece here. But, the Instant Goblet isn't the worst idea I've ever seen, and I'd probably buy a beer just to try it out: http://www.collegehumor.com/post/6890818/8-beer-can-innovations-wed-actually-use
Super funny! Some actually have some potential! I could actually see a market for the corkscrew bottle and beer design/ idea!
The can innovation that is needed now is a can company committed to consistently providing cans to craft breweries. http://www.beeradvocate.com/community/threads/craft-breweries-can-shortage.350506/ Cheers!
Local shop bottleBOX has these for growler pours... now you can get anything you want in a can with a removable top!
The most practical can innovation was when they replaced the pop top, that separated from the can, for the flip top that did not separate from the can. Same design for soft drink cans. Think of all the sea life that now no longer swallow the pop tops. It also eliminated Jimmy Buffets propensity to "step on a pop top."
I miss using the tab part as a spring to send the ring part zinging across the room and into your buddies eye though.
Anyone remember the knuckle buster cans from the 70's? Coors used them - a large dot and a small dot which you had to rap with your knuckle to break them loose and hinge them inward. Got more difficult the more you drank, and you'd end up with a sore and cut knuckle.
I think many states don't allow this type of can because of littering in the past (when cans had the pull tabs). pretty sure that all parts of the can have to stay attached or at least intend to.
I recently got to try one. It's really cool - the bummer is that the ones I had were a Scottish Ale, so I felt I had to pour into a glass. Had they been IPA I would have rocked that can like a beer drinkin' man.
The stackable/interlocking cans would probably not be that difficult to achieve, just a modified sealer for the top and slightly different die for the bottom.
I wish I'd saved one. I'd still like to know how I ever avoided cutting off the tip of my thumb trying to open these.
