ABSTRACT:
A dispenser has a pump device (4) with two hollow pistons (9, 10) which are displaceable coaxially with respect to each other, and wherein one piston is seated at the pump base while the other piston is seated on an actuating button (30). The button continues into a mouthpiece (29) and is surrounded by a bellows (B) which provides an axial restoring force. The bellows (B) forms a piston ring (K) at a distance (A) from the upper end of the actuating button-side hollow piston (9), and slides on a wall surface (b 9') of the button side hollow piston.
