Abstract

A device for coupling two containers comprises connecting branches having essentially circular cross section with each of the connecting branches having a closing member at one end which is essentially circular in cross section for closing the end facing away from the container. When the two connecting branches are brought together, the two closing members are combined into a single member moved by a single actuator so that no clearance is required in each of the branches between the end of the branch and the member. Thus, problems with dirt and atmospheric impurities in a space between the closing member and the end of the connecting member are greatly reduced to prevent contamination of the contents of the container.
