Abstract: A pair of cooler inserts may be used as single units when immersed in a beverage in a container or as a pair when positioned in a cooler of the type designed to hold multi-pack beverage containers. Each insert has a flat top wall, a flat bottom wall, a pair of sidewalls and a pair of flat end walls. Plural concavities are formed in each side wall to accommodate cylindrical surfaces of beverage cans when the inserts are used as a pair to cool multi-pack beverage containers. Posts are formed in the top wall of each insert and post-receiving recesses are formed in the bottom wall of each insert so that a pair of inserts are easily interlocked to one another when a first insert is positioned in overlying relation to a second insert. The flat top and bottom walls ensure that the concavities abut the respective cylindrical surfaces of the multi-pack beverage cans along the entire vertical extent of the cans so that the cans are cooled to the maximum extent possible.

Abstract: A cooling insert for use in a beverage container or in a cooler for beverage containers such as cans which has opposed enlarged ends sized to fit in the beverage container with opposed grooves or concave openings formed in said ends for the passage of a straw or grasping with fingers and with the opposed enlarged ends being connected by an elongated center portion of reduced cross section. The ends being dimensioned so that a pair of inserts are stackable.
