A container for cooling and/or keeping cold beverages and/or foods. The container has a double-walled structure, forming a refrigerant cavity for holding a fluid, such as water, which, when frozen, produces cooling of the beverage or food in the container. A stress-relieving diaphragm accommodates the expansion of the fluid upon chilling to prevent breakage of the container.
