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.

Abstract: A device for receiving and dispensing a coatable material comprises a sleeve-shaped receiving element in which is arranged a piston-shaped element displaceable in longitudinal direction and provided with an internal thread, the element carrying the coatable material and being displaceable by an externally operable socket-shaped rotary grip, wherein the rotary grip comprises a screw spindle co-operable with the internal thread of the piston-shaped element, the device being so improved that detaching of the coating material from the piston-shaped element is reliably avoided without impairing the sealing function.
