Abstract

A device for receiving and dispensing a coatable material such as adhesive, glue, cosmetics and the like. A sleeve-shaped receiving element has a piston-shaped element carrying the coatable material that is displaceable in longitudinal direction by a screw spindle operated by an external rotary grip at the base of the receiving element. The underside of the piston-shaped element is formed to complement the inwardly protruding shape of the sleeve base or grip element, such that there is virtually no free space in which air can collect between the piston-shaped element and the sleeve base when the piston element is fully retracted in the receiving element. Thus the device avoids undesired bubble formation during the filling process, and undesired material break off during use can be largely excluded.
