The safety towards spillage and contamination of the interior of the container in connection with emptying and filling operations is increased by using a spillage-proof coupling as connection between the interior of the container and external connection means. The coupling used comprises a first coupling part (6) mounted on the container (1) and a second part (14) mounted on an external connection means (15) which parts are designed to be engaged in a sealing manner, and valves (12, 19) arranged on the coupling parts. The valves are closed when the coupling parts are separated from each other and open when the coupling parts are engaged, whereby the coupling parts and the valves are designed in such a manner that no volumes from the connecting channel formed by the coupling are exposed between the valves when the coupling parts are separated. |
