When was the beer koozie invented?

The exact invention of the beer koozie is difficult to pinpoint, as similar ideas have existed for centuries. However, the modern, commercially-produced koozie as we know it can be traced back to the 1970s.

Here's a breakdown:

* Early forms: Insulated drink containers have been around for a long time. Sailors used to wrap their drinks in wet burlap to keep them cool, and thermoses were invented in the early 1900s.

* The "Huggie" (1970s): The first recognizable koozie was created by a company called "Huggie" in the 1970s. It was a simple, foam-filled sleeve designed to keep drinks cold.

* The "Kooler" (1980s): The name "koozie" became popular in the 1980s when another company, "Kooler Products," started mass-producing similar products.

So, while the exact date of invention is unclear, the 1970s and 1980s saw the rise of the modern beer koozie as we know it.
