  • Patent number: 5791287
    Abstract: A vessel for transportation of water for animals, having a great resistance to splashing while offering easy access to the liquid. Most of the water within the vessel is below a substantially concave floating dish, while a smaller portion of water is within the dish; the animal accesses only the smaller portion. Water flows from below the dish to above through an opening in the dish. The floating dish prevents the splash of water by floating against an arched lid, blocking the flow of water, and by directing the flow of water under the lid, made possible by protrusions in the lid. Splash as a result of kicking or dropping is prevented by a plate over the hole in the floating dish.
