  • Splash and spill-resistant container
    Patent number: 6142101
    Abstract: An improved splash and spill-resistant container for holding a fluid is disclosed. The container includes a cavity having a top access aperture. A partition divides the cavity into first and second chambers. The partition curves downward from the periphery substantially to the floor of the container and is provided with a flow aperture, thereby allowing fluid communication between the first and second chambers. A valve is also provided to release air from the second chamber when the flow aperture is blocked. After filling the container with a volume of fluid, the container may be subjected to lateral jarring or inverted without spilling the fluid contained therein.
