  • Vapor delivery container with flow distributor
    Patent number: 11166441
    Abstract: A chemical precursor container is disclosed. The container includes a vessel and a lid that define an interior volume, an inlet conduit, an outlet conduit, and a flow distributor positioned inside the vessel and in fluid flow communication with the inlet conduit. The flow distributor has an annular shape and includes a distributor floor having a plurality of apertures formed therein for expelling carrier gas therethrough. The flow distributor includes an inner annular wall that defines a porthole in the flow distributor that allows fluid to pass through the flow distributor from the interior volume of the vessel to the outlet conduit.

  • Diptube design for a host ampoule
    Patent number: 9580293
    Abstract: In one respect, the invention is an improved diptube design for a container for containing and dispensing a liquid chemical, the diptube generating a spring force when compressed that acts to maintain a bottom end of the diptube in contact with a bottom interior surface of the container and a notch located at a bottom edge of the bottom end of the diptube that creates a flow communication between the diptube and the interior volume of the base portion of the container. In another respect, the invention is a method of constructing a container having these limitations.
