I love packaging that actually does somethingâ€”that changes or becomes part of the experience when you use the product. There are three classic examples of packages that I think do this. All were patented in the 1950â€™s or 1960â€™s and all are still in use today… 1. Stripe Toothpaste, 2. Jiffy Pop popcorn, and 3. Pillsbury spiral-wound refrigerated dough containers. I know there are other examples I havenâ€™t thought of, but these are three that mean something to me.
