A device for contamination free and micro-organism penetration preventing, repeated access to a packaging container containing a pourable filling goods, for instance a sterile fluid or powder. A discharge portion forms a sluice space and is connectable into communication with a packaging container of a flexible material or a so called squeezable type container.

Between said valves or discharge openings there is said sluice chamber, which is of such a length that turbulence phenomena at the external valve do not propagate to the interior of the sluice.
