A method and a device for contamination free access to the contents of a packaging container.

摘要

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 (13) forms a sluice space (14) and is connectable into communication with a packaging container of a flexible material or a so called squeezeable type container (10). At each end of the sluice chamber there are arranged closeable and openable valves or discharge openings (15, 16). 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. The basic principle of communicating vessels for the container/discharge portion is applicable. As the latter one forms a form stable sluice chamber, this one permanently will contain a sterile filling goods volume acting as an efficient plug. Any turbulence at the external valve cannot transport bacteria or other organisms through said volume up into the packaging container.
