In 1980, the Radio Cap Corporation (RCC) formally filed a trademark application for the term "koozie". A patent application for an "insulated drink cozy" with an insulating layer sandwiched between outer fabric was made by Bonnie McGough a year later.
McGough's vision for the koozie has evolved, and the one we currently have isn't what she had in mind. Instead, the RCC developed the tight, spherical foam holders that, in the 1980s, were linked to koozies. By the 1990s, koozies had advanced even further, and the rigid koozie had been replaced by softer foam and neoprene.
The Concept of Beer Koozies
A koozie keeps your beverages cold by halting condensation on the can or bottle. Condensation occurs when moist, humid air collides with a colder surface. A koozie acts as a barrier to keep condensation at bay.
Your drink gets warmer because the air around the water droplets that form on the outside of your can or bottle warms them. A koozie delays the onset of condensation and prolongs the cooling of your beverage.
Choose the Best Koozies that are Right for You
A beer koozie is an indispensable companion for any beverage. Using one is the most efficient way to enjoy your summertime refreshments while staying cool. Today, many koozies are available in a variety of styles and colors to keep your convenient beverage bottles and cans insulated and cold.
One example is the YETI Rambler Colster, or yeti beer holder: the Yeti had the coldest beer without the benefit of an ice pack, with temperature rises of just 12 degrees over three hours and 27 degrees over ten hours.
There are other available options on the market today such as ORCA, BrüMate, or Thermos. They also produce koozies although in recent years, when it comes to beer koozies that perform well (while priced very affordably), Yeti has been a popular name that many users love.
Choosing the best one all goes down to what suits your lifestyle and preferences the most.
