  • Publication number: 20210331840
    Abstract: This disclosure relates generally to a containment system for containing a fluid. More specifically, the disclosure relates to a fitment for attaching a liner within a container and providing a fluid path from the liner to an outside of the containment system. The liner and at least a part of the fitment provide the wetted surfaces for the containment system, while the fitment has a portion that can be joined to an outer container that, for example, provides rigidity and light protection. The fitment may be a two-piece fitment with a liner fitment to which the liner may be joined, and a retainer that may be joined to a container, where the liner fitment and the retainer are joined to one another, for example by a mechanical connection. The liner and liner fitment may be fluoropolymers or other non-reactive polymers. The container and retainer may be UV-blocking polymers.

  • Publication number: 20210148474
    Abstract: Welded check valves include a poppet assembly, a spring, and a disc that contacts the spring. The disc may be held at a position away from a weld when forming the welded check valve. Embodiments may include retention features configured to allow one or more of the poppet assembly and disc to pass the retention features in an assembly orientation, and to retain those elements when they are in an operational orientation. Methods include inserting the poppet assembly, contacting the poppet assembly with a spring, inserting a disc, retaining the disc away from a weld side, and welding the check valve together. The poppet assembly and/or disc may pass one or more retaining features when inserted, and be retained by the retaining features when the check valve is operated. The weld may be a thermal weld.

  • Patent number: 10584813
    Abstract: An anti-rotation device for preventing a hydraulic connector assembly from leaking. Various embodiments of the anti-rotation device provide a mechanism whereby threadably engaged connectors, such as compression fittings, are permitted to rotate only a fraction of a turn after loosening. For many applications, the limited degree of loosening is sufficient to prevent the onset of leaking. Structurally, the anti-rotation device can include a band that is secured to a female nut of a hydraulic connector. Protrusions extend laterally from the band and engage with a stop tab on the male body of the hydraulic connector assembly, thereby limiting rotation of the female nut that would otherwise cause leaks. Locking provided by zip tie structures proximate the free ends of the anti-rotation device.

  • Publication number: 20190337823
    Abstract: A fluid circuit includes a plurality of tubing segments and a plurality of operative components. Each tubing segment includes i) a non-conductive polymer portion defining a fluid passageway and ii) one or more interior conductive fluoropolymer stripes extending axially to the ends of each of the respective tubing segments. Each operative component includes a conductive fluoropolymer that extends between a plurality of tubing connector fittings forming a part of the fluid circuit, wherein each of the tubing connector fittings conductively connect the respective conductor of the operative component to the interior conductive fluoropolymer stripes of the tubing segment to provide a path to ground that extends through each operative component and each tubing segment.

  • Patent number: 10443999
    Abstract: A connection verification tool for verifying a secure connection between two fluid handling components of a fluid handling system. A connection verification tool can include a gauge portion sized sized to be placed over a first fluid handling component connected to a second fluid handling component to verify a secure connection between the two components. If the first fluid handling component is not securely connected to the second fluid handling component such that additional torque may be required to complete the connection between the two components, the gauge portion of the connection verification tool will not fit over the first component coupled to the second component.

  • Patent number: 9556012
    Abstract: A bag-in-bag-in-bottle assembly formed by a flexible dispensing container with a dispensing fitment. The dispensing container is positioned adjacent or sandwiched between one or more flexible pressurization containers having a separate inlet/outlet path through a second fitment. The bag-in-bag assembly can then be placed in a containment vessel with the fitments mounted such that it is accessible on the vessel. A liquid can be extracted from the dispensing container by introducing a fluid into the pressurization container(s) with enough pressure to force the liquid out through the dispensing fitment. A contoured dispensing head may be coupled to the bag-in-bag-in-bottle assembly using a cam actuation arrangement for simultaneously locking the pressurization, vent and fluid extraction couplings.
