ABSTRACT:
A lockable closure assembly is configured for an extensible spout container, of the type having a top with an elongate hollow extension extending distally from its surface and an extensible dispensing tube movable within the extension between a retracted position and an extended position, the tube having a distal end with an orifice for the dispensing of a liquid from the container. The closure assembly includes a closure that is internally dimensioned to fit onto the distal end of the tube so as to close the orifice, and a closure retainer element that is configured to seat against a portion of the closure when the closure is installed on the distal end of the tube, and that is internally dimensioned to frictionally engage the extension when the tube is in its retracted position while also engaging the closure. In a preferred embodiment, the closure has an open proximal end surrounded by a peripheral flange, and the closure retainer element is a hollow tubular sleeve having open proximal and distal ends. The sleeve is internally dimensioned to allow the passage of the closure therethrough when the sleeve is passed over the closure. The distal end of the sleeve terminates in an inwardly-directed annular rim that seats against the flange when the sleeve is passed over the closure to engage the extension. The engagement of the sleeve with the extension, and the seating of the annular rim of the sleeve against the flange of the closure, removably lock the closure onto the extension.
