  • Method and packaging for preserving and dispensing portions of a sterile liquid
    Patent number: 5310085
    Abstract: Liquid is enclosed in a resiliently deformable container, the neck of which has a microfiltering membrane which is permeable to the liquid but impermeable to air when wet. Since the container resiliently recovers its shape after it is deformed, the liquid remaining in contact with the outside of the membrane after use is sucked back in and the membrane is kept moist until the next time the container is used.

  • Packaging for altering the composition of a liquid
    Patent number: 5249712
    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.
