Patent number: 11612731Abstract: Quick disconnect fluid coupling devices described herein. The fluid couplings are configured for use in fluid systems for the purpose of providing a low-spill quick disconnect coupling. The fluid couplings include portions that are pivotable in relation to each other to open and close a fluid pathway through the fluid couplings. Particular embodiments of these fluid coupling can be configured to improve medical fluid handling equipment because the fluid coupling devices can be connected and disconnected (e.g., multiple times) while minimizing fluid spillage.Type: GrantFiled: September 28, 2018Date of Patent: March 28, 2023Assignee: Colder Products CompanyInventors: Elizabeth J. Langer, Randall S. Williams, Gary J. Harris

Patent number: 11504518Abstract: Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a repeatable, aseptic fluid coupling system. Such repeatable, aseptic fluid coupling systems are configured to facilitate multiple connection and disconnection cycles while repeatably establishing a sterile fluid pathway through the coupling system. The repeatable, aseptic fluid coupling systems can repeatably establish a sterile fluid pathway through the coupling system even though the coupling system may be used in a non-sterile environment.Type: GrantFiled: November 5, 2020Date of Patent: November 22, 2022Assignee: Colder Products CompanyInventors: Loi T. Truong, Randall S. Williams

Publication number: 20220243848Abstract: Fluid couplings described herein can prevent spillage of fluid when disconnecting the couplings after use. In some embodiments, the fluid couplings described herein include internal valve components but no springs, or no springs in the fluid flow path. In some embodiments, the internal valve components of a male coupling and a female coupling can be designed to latch together in an abutted arrangement. By latching the valve components together, the tendency for fluid to spill when disconnecting the fluid couplings after use can be mitigated, and the necessity to use springs to operate the valve components can be reduced or eliminated.Type: ApplicationFiled: June 8, 2020Publication date: August 4, 2022Inventors: Loi T. Truong, Randall S. Williams

Patent number: 11357963Abstract: An aseptic coupling arrangement can include a first coupling device and a second aseptic coupling device. In one embodiment, the first and second coupling devices are substantially similar, each having a main body defining a front face and a fluid passageway therethrough. A first connecting feature disposed on the main body of each coupling device may be provided for aligning and coupling the aseptic devices together. Each coupling device may also include a sealing member received in the main body and a membrane removably coupled to the main body front face to cover the sealing member. The first aseptic coupling device may also include a rotatable protective cover that is removably attached to the main body and connected to the membrane. In one embodiment, the removal of the protective covers away from two coupled main bodies, in a direction parallel to the front faces, causes removal of the membranes.Type: GrantFiled: April 18, 2019Date of Patent: June 14, 2022Assignee: Colder Products CompanyInventors: Randall S. Williams, Loi T. Truong, Blair D. Plackner, Jeremy H. Nichols

Patent number: 7066356Abstract: The present invention is a foam soap dispenser (10) for push operation. The dispenser (10) houses a product bottle (18 and 18?), and the dispenser (10) includes lock-out members (12a and 12b) while the product bottle (18 and 18?) includes mating lock-out members (19a, 19b, and 19?) to ensure that the correct product is used with the dispenser (10). The dispenser (10) includes a push handle (13) that pivots on a pivot point (16) to dispense product when the push handle (13) is compressed. Pushing the push handle (13) moves the handle lever assembly (25 and 25?) components, which in turn activates a product outlet (23) to dispense the product. As the handle (13) is being compressed and released, a gap (22) is created and an anti-pinch member (14) helps prevent pinching of the hand.Type: GrantFiled: January 2, 2003Date of Patent: June 27, 2006Assignee: Ecolab Inc.Inventors: Allan L. Schuman, Tina O. Outlaw, Darren M. Jahnke, Louis M. Holzman, Randall S. Williams, Paul A. Pilosi, Timothy W. Kidder
