Patent number: 11878903Abstract: A tap assembly for dispensing fluid from a flexible container includes a gland for connecting with the container, the gland having an inlet and an outlet. An actuator is in fluid communication with the outlet of the gland, the actuator including a lever, a removable tamper evident tab and a cap, wherein when the tamper evident tab is in position, the actuator is inoperable and the lever and the cap are fixedly joined and wherein, upon removal of the tamper evident tab, the lever is moveable with respect to the cap to dispense fluid from the tap assembly. A connector is latchable with an outlet of the actuator, the connector including an arm to fixedly engage with the lever in a raised position.Type: GrantFiled: June 10, 2021Date of Patent: January 23, 2024Assignee: ILLINOIS TOOL WORKS INC.Inventor: Yeong-Heng Koo

Patent number: 11390516Abstract: A tap assembly for dispensing fluid from a flexible container includes a gland for connecting with the container, the gland having an inlet and an outlet. A tap is in fluid communication with the outlet of the gland. An incision device is fixed with respect to the tap to rotate with a corresponding rotation of the tap, the incision device located at the inlet of the gland, and positioned fully within the gland in a first rotational position and generally outside of the gland in a second rotational position. An indent and/or rib and/or molded sidewall is positioned on the gland or the tap and a corresponding detent and/or rib and/or tap flange is positioned on an opposite of the tap or the gland such that the tap is rotatable between the first rotational position and the second rotational position and the indent and the detent and/or molded sidewall prevents further rotation.Type: GrantFiled: May 7, 2021Date of Patent: July 19, 2022Assignee: ILLINOIS TOOL WORKS INC.Inventor: Yeong-Heng Koo

Patent number: 8875923Abstract: This invention provides an attachment for mounting electromagnetic identification tags onto the necks of bottles. The tag has a portion which provides a receptacle portion for an RFI tag. This receptacle portion is connected to a portion that embraces a neck of a bottle to attach the receptacle portion, and thereby, the RFID tag to the neck of the bottle. The identification tag may be formed from a material that does not interfere with electromagnetic signals.Type: GrantFiled: September 29, 2006Date of Patent: November 4, 2014Assignee: ITW New Zealand LimitedInventors: Yeong-Heng Koo, Andrew Nicholson Wrigley

Patent number: 8776828Abstract: Known fluid dispensers can suffer from the disadvantage of inadvertent disconnection of a connector causing potentially hazardous spillage of fluid. The present invention relates to a fluid dispensing assembly comprising a tap and a connector body. The tap comprises a first valve, movable between an open and closed position to allow fluid flow through; and a first portion of an interlocking coupling, configured for rotational engagement with a second complementary interlocking coupling portion of the connector body by rotation about a first fluid dispensing assembly axis. The connector body also comprises a second valve, movable between an open and closed position to allow fluid flow through. By this configuration, the first and second interlocking coupling portions remain interlocked preventing disconnection of the connector body from the tap unless the first and second valves are both in the closed position.Type: GrantFiled: July 1, 2010Date of Patent: July 15, 2014Assignee: Illinois Tool Works Inc.Inventors: Yeong-Heng Koo, Andrew Nicholson Wrigley

Patent number: 8602387Abstract: This invention provides a valve for a flowable material. The valve has a body defining a bore defined therein. An opening is defined in the side of the bore for material to flow from the bore. The valve also has an actuatable member which is movable along the bore to control the extent of an uncovered area of the opening defined in the bore to control the flow of material through the opening.Type: GrantFiled: November 9, 2006Date of Patent: December 10, 2013Assignee: ITW New Zealand LimitedInventors: Andrew Nicholson Wrigley, Yeong-Heng Koo, Matthew James Towers

Patent number: 8561846Abstract: Tap assembly configured to resist release of the tap when an internal vacuum is applied to the tap and to maintain aseptic conditions of fluid within an attached fluid container before first use of the tap. The tap assembly having an actuation member configured to cover at least a portion of a bore within a body; a cover configured to substantially enclose and abut a proximal portion of the actuation member to prevent actuation of the actuation member by engaging with the body; and a piercer element positioned on an end of the actuation member proximal to a sterility membrane sealed over the bore and including at least one projection to pierce the sterility membrane when the actuation member is actuated during first use of the tap assembly.Type: GrantFiled: November 1, 2010Date of Patent: October 22, 2013Assignee: Illinois Tool Works Inc.Inventors: David R. Hauner, Andrew N. Wrigley, Yeong Heng Koo
