Patent number: 8733592Abstract: A liquid supply system capable of being serviced and hygienically maintained easily. A beer storage barrel switching device (12) uninterruptedly supplies beer by switching between beer storage barrels (21-1, 21-2). A first connection tube (23-1) is provided with a fluid stopper device (31-1) including a loop section. The fluid stopper device (31-1) switches between a suppliable state in which it is possible to supply the beer to a dispenser (11) through the first connection tube (23-1) and a non-suppliable state in which it is not possible to supply the beer. Using the fluid stopper device (31-1) eliminates the need to provide a conventional valve in the middle of the first connection tube (23-1), the conventional valve having a structural element which comes in direct contact with the beer. Accordingly, the case that a cleaning member, such as a sponge, is caught by the valve does not occur, and this enables the inner wall of the first connection tube (23-1) to be cleaned using the cleaning member.Type: GrantFiled: June 2, 2010Date of Patent: May 27, 2014Assignees: Asahi Breweries, Ltd., Kyokko Electric Co.

The fluid dispense system is particularly well suited to be manufactured in a single-use format comprising a fluid reservoir and fill tube assembly, particularly comprising a reservoir, tubing, fittings and connectors, and a needle. The system ensures uniformity within the liquid by moving the fluid through the product reservoir such as with a continuous or pulsating flow, and is designed to maintain the fluid in motion in order to maintain a homogenous solution. The reservoir is designed to minimize any fluid dead zones.Type: GrantFiled: January 4, 2007Date of Patent: May 31, 2011Assignee: Millipore CorporationInventors: Robert C. Saunders, Brett M. Belongia

Publication number: 20110100503Abstract: A dispensing device capable of no-leak dispensing of a liquid when the dispensing device is in fluid communication with a defective liquid container, including an apparatus enabling the movement of liquid from the liquid container to a holding tank in fluid communication with the liquid container and associated with the dispensing device. The apparatus includes one or more sealing mechanisms which permit ambient air to enter the liquid container through an air path as necessary to enable uninterrupted dispensing, and also permits substantially none of the liquid or only minimal amounts of the liquid to flow out of the holding tank and through the air path, in a no-leak manner, during periods when there is no dispensing.Type: ApplicationFiled: November 3, 2009Publication date: May 5, 2011Applicant: MTN PRODUCTS, INC.Inventors: Chun Yen Wang, Tony Xiao, Lim Chin Tien

Patent number: 7896197Abstract: A fluid dispensing device, suitable for dispensing fluid from a fluid supply to a receptacle, is disclosed, wherein a pliable fluid reservoir is located between the fluid supply and the receptacle, and wherein peristaltic pumps are used to supply and dispense said fluid from the pliable fluid reservoir. The fluid level in the pliable fluid reservoir is electronically monitored with data being transmitted to either or both pumps for the operative control thereof. The pliable fluid reservoir is configured, together with certain connected conduits, as a disposable, easily-installable, single-use unit.Type: GrantFiled: November 19, 2004Date of Patent: March 1, 2011Assignee: Millipore CorporationInventors: James F. Furey, Mark McInnes

Patent number: 7878372Abstract: An automatic water cooler replenishing system for a free standing water cooler, having an internal reservoir. The system includes a pump having an inlet port and an outlet port configured for collecting water from a supply bottle and dispensing water into the reservoir. The pump is selectively powered and automatically controlled. A relay is provided for automatically controlling the operation of the pump. The relay is configured to receive an electric signal and control the pump. A fill control assembly and a low water shut-off assembly are electrically connected to the relay. The fill control assembly is configured to detect at least one water level, in the reservoir and signal the relay to energize or de-energize the pump. The low water shut-off assembly is configured to detect a low water condition in the supply bottle and signal the relay to de-energize the pump.Type: GrantFiled: March 7, 2008Date of Patent: February 1, 2011Inventor: Esteban Camejo

Patent number: 7874325Abstract: An apparatus and method for emptying and filling a fluid container. A flow-actuated valve inside a fill tube regulates the flow through the fill tube. A cap containing the valve and a vent tube can be installed on a modified bottle used to supply water dispensers, thus enabling a user to continuously replenish the bottle from a remote supply. Alternatively, a cap containing the valve, a vent tube, and two fluid level sensors can be installed on a conventional bottle. A user is thus relieved of the burden of repetitive bottle changing, and is able to treat the water to his own specifications.Type: GrantFiled: December 8, 2008Date of Patent: January 25, 2011Inventors: Michael E. Tyler, Paul M. Whetstone

Patent number: 7810674Abstract: A dispense apparatus and system for dispensing suspensions or emulsions. The system ensures uniformity of distribution of the dispersed phase within the continuous-phase liquid by moving the fluid through the dispense cartridge, such as with a continuous or pulsating flow. In one embodiment, peristaltic pumps are positioned upstream and downstream of the dispense cartridge, in fluid communication with and forming a single loop with a fluid source. Circulation between the fluid source and the dispense cartridge is maintained. In a second embodiment, a pump circulates fluid into and out of the dispense cartridge and is also in fluid communication with a fluid source such as with a pinch valve to allow proper filling of the dispense cartridge from the fluid source. In a third embodiment, a reversing pump is placed between the dispense cartridge and fluid source to continually or continuously pump fluid into and out of the dispense cartridge.Type: GrantFiled: July 26, 2005Date of Patent: October 12, 2010Assignee: Millipore CorporationInventors: Brett M. Belongia, Robert C. Saunders

Publication number: 20100243667Abstract: A fluid dispensing apparatus is configured to dispense a predetermined volume of fluid, and includes a fluid reservoir to hold a fluid to be dispensed, a dispense tube to dispense the fluid, and an elevator mechanism. The fluid reservoir receives a fluid from a fluid supply. A dispense tube has a dispense outlet, and is connected to an outlet port on the fluid reservoir. The elevator mechanism changes a relative vertical displacement between the dispense outlet and the outlet port. Particularly, a processor controls the elevator mechanism to raise the dispense tube to a raised filling position to prevent fluid flow from the dispense outlet, and lower the dispense tube to a lowered dispensing position to dispense the fluid.Type: ApplicationFiled: June 10, 2010Publication date: September 30, 2010Inventors: Denis E. Keyes, John R. Randall

Patent number: 7757891Abstract: Techniques for dispensing a type of liquid in a specific amount or at a constant flow rate are disclosed. According to one aspect of the present invention, a height difference between an inlet and an outlet is maintained by an adjustable tubing assembly. An overflow assembly is provided to divert any overflow of the liquid from entering a reservoir and keep a specific level of the liquid. A valve is provided to the inlet and can be turned off when a sensor detects that there is an overflow of the liquid in the overflow assembly.Type: GrantFiled: March 14, 2007Date of Patent: July 20, 2010Assignee: ChemFlow Systems, Inc.Inventors: Leon Han, Russell D.
