Abstract: A pour spout device is a unitary construction molded of flexible plastic, including a base cap and an elongated spout tube. The base cap has a lower section and an upper section joined at a lower shoulder section. The base cap lower section has an outer surface and a first set of threads formed on a first inner surface of the lower section. The base cap upper section has an outer surface and a second set of threads formed on a second inner surface. The first and second sets of threads have decreasing thread diameters, such that the first set of threads fits the opening of a bottle that is larger than a bottle that fits the second set of threads. The flexible plastic is a thermoplastic rubber having material characteristics such that the spout tube is flexible to bend and close by finger pressure, yet not take a set when repeatedly bent.
