freezer block
Cooler's cold keeper
A freezer block is a sealed plastic container filled with gel or liquid that, once frozen, keeps food and drinks cold in a cooler or insulated bag.
Unlike ice, freezer blocks don't create a watery mess as they thaw: Pack a couple of freezer blocks with your lunch.
Also called an ice pack or cold pack.
