ABSTRACT:
A twin-chamber container which includes an outer plastic container with a valve mounted thereon and an inner collapsible container mounted in communication with the valve. A space between the container is pressurized to collapse the inner container when the valve is opened for permitting the dispensing of material from the inner container. A flowable resin is located in the space between the containers where it hardens at the area of the opening in the outer container having the valve arrangement for forming a seal. A method for preparing a twin-chamber container, ready to be filled with a product, involves pressurizing the intermediate chamber between the outer container and the inner collapsible container with a gas and transporting the twin-chamber container with the pressurized intermediate chamber to a filling station for filling a product into the inner container through the valve of the container.
