Abstract: 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. At each end of the sluice chamber there are arranged closeable and openable valves or discharge openings. 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.

Abstract: A packaging tube including a body formed from a laminate containing a metal foil and a plastic layer is provided with a strip also formed from a laminate incorporating a metal foil and a plastic film. The metal foil in the strip is thicker than the metal foil in the body laminate. The strip provides dead-fold characteristics. The strip may extend along a joint, such as a butt joint, in the tube body so that the strip covers the joint.
