  • Patent number: 4724615
    Abstract: A medicine spoon has a spoon bowl with a handle, and a flat cover completely covers the bowl in a closed position in which the cover bears against the edge of the bowl. The cover has a handle attached to the bowl handle for pivotal movement between the closed and open positions, and the cover has an opening through which an amount of a foam product from a dispenser may be fed to the bowl in the closed position of the cover. The underside of the cover scrapes along the upper edge of the bowl for wiping the underside clean during movement of the cover to its open position. Stop shoulders in the form of continuous flanges are provided on the bowl and cover for both limiting the cover to its completely closed position and for preventing leakage of product through the cover when filling.
