Abstract: A package for a liquid which is purified includes a neck with a lock-chamber slidable therein. The lock-chamber includes a purifying substance through which the liquid passes when dispensed. At one end of the lock chamber, a plug is positioned to block passage of the liquid through the lock-chamber when the lock-chamber is projected from the neck and to allow passage of the liquid when the lock-chamber is pushed down into the neck.
