ABSTRACT:
A refrigerant puck for insertion into an insulated beverage container holder. A portable beverage-filled container is inserted concentrically into the insulated holder such that a bottom surface of the beverage container contacts a top surface of the refrigerant puck which permits conductive heat transfer to occur, thus keeping the beverage container cool for an extended period while facilitating the consumption of a beverage therefrom. The refrigerant puck includes a disk-shaped container, preferably formed from a high-intensity polyurethane or polyethylene, which has a raised top surface that is substantially convex to mate with a concave bottom surface of the beverage container, thus ensuring a continuous and uniform contact with the majority of the bottom surface of the beverage-filled container which provides a direct cooling effect. The disk-shaped container further has a substantially concave bottom surface which mates with the convex top surface thereof which enables a plurality disk-shaped containers to stackably nest one on top of another. The convex top surface and the concave bottom surface of the disk-shaped container each have a slight flat uppermost surface. This uppermost surface is provided to display indicia, such as an advertisement or a logo. This flat surface does not interfere with the ability of a plurality of refrigerant pucks to be stackably nested together. The disk-shaped container is filled with a non-toxic liquid refrigerant solution which imparts the aforementioned cooling effect on the beverage-filled container.
