<p>A paint dispenser comprising a supply container connected in a paint supply path and a paint delivery path including a dispensing head having a tubular part with an outlet opening and pin member mounted in the tubular part. The pin member can be moved back and forth between a position in which it partially closes the paint delivery path and an open position, into which the pin member can be retracted to prevent the after-drip of paint, thereby promoting the dispensing of accurately metered amounts of paint. This is further promoted by including a pump in the paint delivery path and providing a return conduit connected to said paint delivery path and terminating in the supply container, and including a filter and/or a restriction means in the paint delivery path.</p> |
