A cubic plastic container has a cylindrical neck formed centrally in its top defining a mouth for the container. The top of the neck is provided with a collar capable of receiving a snap fitting cap. The container also has circular recesses formed centrally in its bottom and two opposing sides. The recesses are sized to snuggly, but releasably, receive the neck of another such container so that the two containers may be coupled by the engagement of the collar of one container with the sidewall of the recess of the other container.
