ABSTRACT:
A fluid dispensing device for applying fluids which dry and harden with exposure to ambient air, typically glues and the like. The device includes a sponge applicator. A flexible container element has a first thread for engaging a dispensing element, including the applicator. A neck portion of the container element includes a second thread on an outer surface thereof for selective engagement with a cap-like cover which encloses the sponge and prevents drying of the same during periods in which the device is not in use. The sponge includes an axially-aligned passage interconnecting directly with the neck portion, so that the squeezing of the container element transfers the dispensed fluid directly to an outer surface of the sponge for application to a treated surface.
