ABSTRACT:
The present invention is directed to a variable volume film drum with a proportionally variable length conduit path for directing and controlling the flow of fluids introduced into the drum. The center conduit path is comprised of interconnecting conduit reels also used to hold the film. Each conduit reel has an internal conduit path, one end of which forms an outwardly extending flange or male portion and the distal end forms a receiving or female portion. As the volume of the container is varied to accommodate more or less reels, the conduit path formed by the interconnected reels is proportionally altered. The conduit reels are further connected to a fluid inlet tube in the film drum to complete an integral path for the introduction of fluids into the drum.
