A dispenser for cream, sauces, jelly, pastes, syrups or the like which has a main cylinder and a guide cylinder coaxially arranged within it. The annular space between the cylinders is divided into an intake space and a feed space by a displacement piston which allows for drawing the material to be dispensed from a container through an intake passage in the main cylinder and discharging the material through an outlet opening in the forward end of the main cylinder. A closure element is normally biased against the outlet opening and a plunger is provided at the rear end of the main cylinder, bearing against the piston and normally biased in the outward position.
