Abstract
A liquid dispenser that is adapted for use with an applicator to apply liquid coatings. The dispenser has a first tubular housing in which is slidably received a second tubular housing. A liquid tight seal is provided between the two housings to define a liquid reservoir and the second housing has an outlet channel in fluid communication with the reservoir. The second housing has an inlet with a valve which allows fluid flow into the reservoir from an external source but prevents fluid flow from the reservoir when the external source is disconnected. A pressure differential is established between the external fluid source and the reservoir to fill the reservoir.
