Six pack rings
The six pack rings in most common use today are the descendants of an original design by ITW Hi-Cone, which first introduced them in St. Louis, Missouri in the summer of 1960. Within 10 years, plastic rings had completely replaced the paper and metal based holders then common in the market. Today several other manufacturers continue to produce six pack rings. Though interest in multi-packs has continued to grow, other variations, including paperboard baskets and HDPE plastic can carriers have grown in popularity, providing an alternative to conventional six pack rings.
Since the late 1970s, six pack rings have been cited as a particularly dangerous form of marine litter as marine wildlife used to be found entangled in the rings, sometimes strangling to death. But since 1989, six-pack rings have been manufactured to be 100 percent photo-degradable, so the plastic will begin to disintegrate in sunlight in just a few days. This allow animals to easily escape from the brittle and crumbling rings. This is in accordance with the U.S. Federal regulation for testing plastic photo-degradation, which is 40 CFR Ch. I (7–1–03 Edition) PART 238.
In pop culture
- In the Futurama episode "Obsoletely Fabulous", six ducks are trapped in the same six pack ring, who are then mistaken for beer cans by the robot Bender.
- The 2006 animated film Happy Feet features a penguin whose head is trapped in a six pack ring.
- In The Simpsons episode "The Old Man and the Lisa", Montgomery Burns attaches millions of "recycled" six-pack holders together into a net, which he uses to catch tons of sea life and make "Li'l Lisa Slurry".
