Abstract: A single use sealed container assembly for a large format ice unit includes a container having an open end and a closed cavity defining a predetermined volume of at least three fluid ounces, and up to about six fluid ounces. A seal assembly has a cover member dimensioned to completely overlie the open end of the container. A seal is disposed between the container and the cover member, wherein the seal at least temporarily maintains the cover member in a sealing engagement over the open end of the container. An amount of a liquid product is maintained in the closed cavity of the container by the cover member until such time as the container assembly is placed into a freezer, thereby forming a large format ice unit therein, which may be accessed by a user by removing the cover member from the open end of the container.
