Adaptable cooling sleeve for beverage containers

Abstract

The present invention relates to an improved adaptable cooling sleeve to maintain or lower the temperature of a beverage. Embodiments of the present invention provide an adaptable cooling sleeve device, hereinafter referred to as the sleeve, having a securing mechanism, a cooling pack that stabilizes the temperature of the beverage container, and an insulating exterior layer. The securing mechanism allows the device to be adjusted to allow the sleeve to accommodate beverage containers of a variety of shapes and sizes. The cooling pack comprises a coolant, such as a liquid or gel, that acts as a temperature stabilizing heat sink for the beverage contents for a period of time. The insulating exterior layer thermally isolates the contents of the beverage and the cooling pack from the atmosphere.
