An improved dispenser for pastes is disclosed comprising a variable volume paste chamber, a dispenser nozzle communicating with the chamber for dispensing paste, a displaceable element displaced by room pressure, as a result of a reduced pressure in the paste chamber, an actuating member, accessible from outside the container and displaceable from an inactive to an active position, an elastic element, a means for applying a force to the elastic element in such a way as to reduce the volume of the chamber, thereby causing said paste to be dispensed through said dispenser nozzle, when said actuating member is displaced from the inactive to the active position, a kinematism for kinematically connecting the actuating member to the means for applying a force to the elastic element when the actuating member is displaced to its active position, and for allowing the elastic element elastically to return to its base configuration when the actuating member is returned to its inactive position, and a support means for holding the paste container in a predetermined position when a force is applied to the elastic element.
