Publication number: 20220096325Abstract: Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions and thread finishes. In one embodiment, an enclosure system may include a plug having a sleeve extending therefrom. The plug may be deformed manually or via a plunger system to reduce the outer dimension thereof to fit the plug in the neck of a fluid container. Once the plug is arranged within the neck, the sleeve may be folded down over an outer surface of the neck to form or reinforce a seal between the enclosure system and the neck of the fluid container. Other embodiments are described.Type: ApplicationFiled: September 21, 2021Publication date: March 31, 2022Inventors: Laura E. Christakis, Ryan V. Wales, Scott E. Brechbiel
