A container assembly for use with a high-pressure liquid chromatography (HPLC) instrument is disclosed, in which the container assembly, when coupled to a source of pressurized gas, provides fluid medium to the HPLC instrument at positive pressure. The container assembly has an external exterior container shell, an internal fluid container for holding fluid medium, an interstitial volume between the external exterior container shell and the internal fluid container, a port for fluidly connecting the volume to a pressurized gas source, and a port for fluidly connecting the internal fluid container to the HPLC instrument. As a pressurized gas in the interstitial volume increases, fluid medium flows out of the port connected to the internal fluid bag and container assembly at a positive pressure. A system incorporating the container assembly, and method of use of the same, are also disclosed.

A system for high pressure processing of bulk, high viscosity flowable product includes a carrier having openings therein for receiving high pressure fluid into the carrier. A flexible product bag is disposed in the product carrier, the bag having a fitment for filling and emptying the bag with high viscosity, flowable product. An opening in the product carrier for access to the fitment. An emptying system cooperates with the carrier to act on the filled product bag to increase the pressure on the product in the product bag to assist in forcing the high viscosity product out of the product bag. A control system controls the operation of the emptying system.

A liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are contained in the chamber. The first conduit connects the chamber to an outlet port in the container were the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an exiting flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

A novel canister storage system, mixing system, canister assembly, dispensing system, and tracking system. In one or more embodiments, the systems are used for storing, mixing and dispensing fluids. In one application, the fluid includes one or more paint toners.

The first conduit connects the chamber to an outlet port in the container where the second conduit connects the bag to the first conduit. A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an existing flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid. The second conduit lacks flow restrictions, such as metering orifices or the like.

A method of assisting in refilling a container (11) with liquid, the container comprising a flexible pouch that is refillable with liquid, outer packaging (15) for the pouch, and a valve (16) for opening/closing the pouch, said pouch being a compressible pouch that can be shrunk inside the outer packaging (15) under the action of pressure exerted on the outside surface of the pouch, and said valve (16) comprising a valve body (17) provided with an orifice (18) and a shutter for the orifice (18) mounted to move inside the valve body (17) between an open position and a closed position for the orifice (18) so as to enable the pouch to be emptied when the pouch is in the compressed state and the orifice (18) of the valve (16) is open.

In order to refill the pouch subsequently with liquid, said method comprises a step of opening the orifice (18) of the valve (16), and a step of inflating the pouch by blowing gas into the inside of the pouch via the orifice (18) of the valve (16) in the open position.

A water storage tank is provided with a water storage bag for storing finished water and a space for accommodating squeezed water outside of the water storage bag. The water storage tank enables a rapid introduction of squeezed water by having a flow guiding groove connected in communication with the space for accommodating squeezed water. A hollow tube extending into the water storage bag is arranged to prevent distortion of the water storage bag, so as to completely squeeze the finished water out of the bag. A cylindrical middle part and two ellipsoidal or hemispherical ends of the water storage tank can improve the stress bearing performance of the water storage tank. A household water purifier using the water storage tank is also described.
