ABSTRACT:
A container for storage, transport and dispensing of liquid chemicals uses a collapsable thin film pouch which is sealed to a fitment and is positioned within a bottle or overpack. A retainer and cap hold the pouch and fitment in place within the bottle. The cap provides an inner seal and an outer seal which remain intact during shipping and storage. In use, the outer seal is removed and the container is connected to either a manual or an automated dispensing system which includes a valve probe which breaks the inner seal. In the manual system the bottle is inverted so that flow of liquid from the pouch is gravity assisted. In the automated system, the container is placed within a pressure vessel and air pressure is applied both to the outside of the bottle and also to the inside of the bottle to assist in collapsing the pouch and forcing the liquid out of the pouch. When empty, the container is removed from the manual or automated dispensing system and the cap and retainer are removed to allow removal and disposal of the pouch and fitment.
