Patent number: 11344670Abstract: An infusion pump includes a core member and a bladder member which are substantially spheroidal at one end and cylindrical at the other end. The core member is inserted inside the bladder member and a ring member engages the cylindrical ends of the core and bladder member to sealingly secure the bladder to the core. A tubular hose is included and is coupled with an infusion port of the core member. When fluid is injected into the pump, it causes the bladder member to inflate substantially symmetrically and spherically around an axial axis of the core member. Upon deflating the bladder member, the fluid is ejected out of the pump at a constant flow rate.Type: GrantFiled: October 3, 2019Date of Patent: May 31, 2022Inventors: Mark Shal, Kurt Sebesta

Patent number: 5865217Abstract: A filling system of a packaging machine is set forth that reduces the mixing of product and air during the filling of the container with a flowable material such as low fat milk. The fill pipe of the filling system has an elliptical cross-section which provides for a reduced velocity of the flowable material entering the container while allowing for an increased production time of the packaging machine. The fill system is especially adopted to fill containers having a rectangular cross-section. Connected to the fill pipe is a nozzle with flaps designed to substantially conform and engage with the sidewalls of a container. When the flaps are urged to an open position, the mixing of air and product is inhibited as the flowable material is dispensed into the container through the nozzle and as a moving mechanism is operated to relatively move the container and nozzle from a first to a second position. The fill pipe has an elongate body, an inlet end and an outlet end.Type: GrantFiled: March 6, 1997Date of Patent: February 2, 1999Assignee: Tetra Laval Holdings&Finance, SAInventors: Peter Giacomelli, Robert Muns, Anders Andren, Par Svensson
