Abstract: In one aspect, the invention is directed to a portable paste dispenser having a container for storing paste, the container having a cylindrical part and a conical part, a nozzle at the end of the conical part, a piston, disposed inside the cylindrical part of the container, and a shaft connected to the piston, the shaft having a limited foldability so that when the shaft is pushed towards the piston, it still is able to move the piston along the cylindrical part, where the piston includes foldable bellows walls, thereby upon applying force on the piston, the piston straightens up, resulting in a conical form correspondingly to the conical part, thereby allowing fully emptying the container.
