Abstract: An elastomeric valve includes a barrel having one or more walls defining an interior fluid pathway. The barrel is deformable between a non-deformed state and a deformed state. The elastomeric valve further includes a gate assembly of two or more gate elements forming a tapering volume projecting into the fluid pathway from the one or more walls of the barrel. In at least some examples, each gate element joins the barrel at a reduced cross-section that forms a hinge of that gate element. The two or more gate elements interface with each other along one or more gate boundaries to collectively block the fluid pathway in the non-deformed state and separate from each other along the one or more gate boundaries in the deformed state to permit fluid flow through the gate assembly.

Abstract: A valve system includes a fitment or a fluid container having a threaded spout, a valve assembly, and a cap. The threaded spout has external threads. The valve assembly includes a sleeve forming a barrel. The barrel includes internal threads and external threads. The internal threads accommodate the external threads of the spout at a first end of the barrel. The valve assembly further includes a valve located at a second end of the barrel. The valve is operable to open and close an internal fluid pathway of the valve assembly. The cap defines an interior region that includes internal threads that accommodate the external threads of the barrel. The cap accommodates the valve within the interior region when the internal threads of the cap are fully threaded onto the external threads of the barrel. The cap may contact the valve to provide an additional seal.
