RELATED APPLICATIONS

There are no previously filed, nor currently any co-pending applications, anywhere in the world.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to insulated beverage holders and, in particular, to an insulated beverage holder that utilizes a freezable gel layer to maintain the cold temperature of canned or bottled beverages for an extended period, addressing the limitations of traditional koozies.

2. Description of the Related Art

Insulated beverage holders, commonly referred to as “koozies,” have been widely used to maintain the temperature of canned beverages. These holders are designed to provide insulation between the beverage can and the ambient environment, as well as the user's hand, which can transfer heat to the beverage. However, traditional koozies have several limitations that affect their effectiveness in keeping beverages cold for extended periods.

This results in a number of existing problems and needs, including:

• • Low Insulation Value: Standard koozies offer minimal insulation due to their thin, lightweight materials. This results in a rapid heat transfer from the surrounding environment to the beverage, causing it to warm up quickly.
  • Room Temperature Starting Point: Koozies are typically stored at room temperature, which means that when a cold beverage is placed inside, the koozie itself begins to warm the beverage immediately. This further contributes to the rapid temperature increase of the beverage.
  • Short Cooling Duration: Due to the low insulation value and room temperature starting point, beverages in traditional koozies start to lose their desirable cold temperature within a short period. Users are often left with the option of consuming the beverage at an unsatisfactory temperature or discarding it.
  • Lack of Rechilling Options: Once a beverage in a koozie has warmed up, users have limited options to re-chill it. Adding ice to a canned beverage is impractical, and placing the beverage back in a refrigerator would require waiting for an extended period before it returns to a desirable temperature.
  • Need for Extended Cooling: There is a need for an insulated beverage holder that can maintain a cold temperature for a significantly longer duration, allowing users to enjoy their beverages at a refreshing temperature throughout their consumption.

Consequently a need exists for a solution that addresses the limitations of traditional koozies.

SUMMARY OF THE INVENTION
