Abstract
A liquid dispensing container of the squeeze bottle type has a low center of gravity liquid bottle with a hemispherical base portion and a frusto-conical neck portion. A spout assembly is coupled to an upper end of the neck portion for dispensing liquid when a deformable bottom wall of the base portion of the bottle is flexed. The spout assembly includes a bottle cap with a through bore in which a flexible dispensing tube is slidably extensible and retractable to dispense liquid, such as lubricating oil, into locations that would otherwise be inaccessible. A wiper element in the bottle cap associated with the through bore provides a liquid impervious seal between the bottle cap and the tube and ensures that excess liquid on the outer surface of the tube is scraped off as the tube is extended. A nozzle is connected to a distal end of the tube and a pop-up sealing cap is slidable back and forth over the nozzle to selectively open and close a dispensing hole in the pop-up cap.
