Call me a huge dork, but I’m really excited about this new milk jug design taken up by Wal-Mart and Costco. They’re rectangular, allowing them to be packed far more tightly in shipment, use less packaging, and have a greatly reduced overall environmental impact. This is precisely the sort of small manufacturing modification that big business has been without incentive to make while fuel was cheap, but that has been so badly needed. (I’ve been chewing over the design of the cereal box for the past couple of years. There’s a package ripe for improvement.) It’ll take a bit for people to learn this new jug, to adapt to the idea of tilting it in place, rather than lifting it up, but that’s an easy hurdle. My only concern is who owns the patent on this jug, and whether they’re charging for its implementation. Our milk comes in glass bottles, on which we pay a deposit, so I won’t be trying these new jugs anytime soon.
