Abstract: A container system for mixing and dispensing that comprises two containers, each container holding one or more ingredients. A first container is sealed with a frangible seal. A second container is sealed with a reusable cap and closure. At the time of use, the containers are able to be joined in a way that creates a passageway from one container to the other, which allows the ingredients in each container to mix. When the containers are separated, the first container is empty, and the second container holds the mixed ingredients. The second container can be fitted with the reusable cap closure to seal off the mixed ingredients from the ambient environment.
