  • Patent number: 7753240
    Abstract: A closure for a liquid container includes a spout and a loop member extending upwardly from an end wall of the closure. The loop may be sized to receive a user's finger or attachment hardware such as a clip, hook or strap extending through the loop. A flip cap is supported for rotational movement on the loop and is movable between a closed position in which the spout is covered and an open position in which the spout is exposed.

  • Patent number: 6752183
    Abstract: A waste funnel system for pouring liquids into a container. The waste funnel system has an adapter with a closure that can be mounted to an opening of the container. A funnel body has a cover that is pivotally connected to the funnel body and is used to open and close an inlet end of the funnel. The funnel body is also assembled in the adapter, thereby permitting different size funnel bodies to be assembled with the same container closure. A ventilation path extends between the funnel body and the adapter to permit vapors to be displaced from an interior of the container. In addition, a screen disposed in a liquid path between inlet and outlet ends of the funnel body prevents objects from passing through the funnel system.
