A molded plastic container top has an upper surface from which extends an extensible dispensing tube with a liquid dispensing orifice. The orifice is closed by a removable closure in the form of a cap-like, hollow, open-ended body. A plug is formed integrally with the upper surface and extends upwardly therefrom. Extending upwardly from the plug is an integral, cylindrical, rod-like stopper extension. In the preferred embodiment, the plug is axially fluted, with three radial vanes, dimensioned to be received into the interior of the closure to retain the closure thereon with a frictional fit. The stopper extension is dimensioned to be received within dispensing orifice with a fluid-tight fit, so as to provide an alternative closure for the orifice when the dispensing tube is extended to bring the orifice into the proximity of the stopper extension. The maximum thickness of the vanes is less than or equal to the thickness of the top at the upper surface, so that the formation of the plug does not leave a significant "sink mark" on the underside of the top, opposite the plug. The ratio of the maximum thickness of the vanes to the thickness of the top at the upper surface is advantageously in the range of about 1:3 to about 3:4, with a specific preferred embodiment having a ratio of about 2:3. Other ratios, less than or equal to 1:1, should provide satisfactory results, depending on the type of material used, and the thickness of the top at the upper surface.
An improved container top, of the type having an elongate hollow extension extending upwardly from its upper surface and an extensible dispensing tube slidably disposed in the extension, the tube having an orifice for the dispensing of a liquid from a container to which the top is attached, the top further including a removable closure for the orifice, the closure comprising a substantially cylindrical body with an open end communicating with a hollow interior, wherein the improvement comprises:
