When I got there I noticed the thing had a wierd plastic plug where the opener would normally be, apparently this is a new thing coke has come up with:

This is actually really interesting and potentially impactful. One of the main reasons bottles are still around (glass bottles that is) is that cans can't be resealed. The mechanism itself is very simple but also very clever, a firm fitting rotary valve that you can unscrew pretty easily with a thumb once you take off the tab, but that certainly will stay shut bouncing around. It's quicker and easier to unscrew than a bottle top and while I'm unsure of the cost, if Coke can find a way of making these in such a way that they don't significantly add to the cost of their regular cans, I can imagine this being a big deal not just for soft drinks, but alchoholic beverages, particularly those not typically sold in cans like wine or spirit mixes and even canned liquids used for cooking (though the size of the valve release is to fine for anything syrupy or with solid bits).
Most notably, sporting venues would kill for this, with all the issues with glass bottles and cups have caused.
I'm wondering if you've run into these cantops before and what your experience has been. Would you be willing to pay an extra 5c a can or so for this mechanism? would you be interested in this sort of thing on alcho-cans or even cans of stuff like coconut milk tomato juice etc?
With so much gimmicky bullshit in the commercial market these days, I always love it when someone comes up with something genuinely clever and potentially useful to differentiate their stuff.
