The invention relates to a dispenser for dispensing fluids from a fluid container, comprising a dispenser head provided with a dispenser nozzle; a dispenser base, holding the dispenser head, provided with a coupling for connection to the fluid container; and a fluid feed leading from the dispenser nozzle into the dispenser base for connection to the fluid container; wherein the fluid feed is provided with at least one valve. The invention also relates to a fluid container provided with a dispenser as well as a method for dispensing fluids from a fluid container.

Dispenser and method for dispensing fluids from a fluid container

A novel pumping device () with an actuator () and a head part () for dispensing a fluid from a container () is described. The actuator () comprises an outlet conduit () and a first cylindrical member () and the head part () comprises a second cylindrical member () which is arranged coaxially to the first cylindrical member. A folded membrane member () with an inlet valve () and an outlet valve () is provided between the first () and second () cylindrical members, such that the first () and second () cylindrical members and the folded membrane member () provide a variable pump chamber (). The outlet valve () is arranged relative to the actuator () in such a manner that a suck-back chamber () with a variable volume is provided between the outlet valve () and the outlet conduit (), which is simultaneously reduced as the pumping chamber () is reduced.

Pumping device for a fluid container

A cartridge gun is provided. The cartridge gun comprises a cartridge holder, a plurality of resilient gripping elements, a displaceable piston rod for moving a piston in a cartridge, and an actuating device for displacing the piston rod. The cartridge holder comprises a cylindrical base for receiving the floor region of the cartridge in which the gripping elements project radially outwardly from the center of the cartridge holder in the direction towards the housing into an annular groove of the base up to the outside wall of the annular groove in the base and are held in the center of the base by means of a hub. Means are further arranged at the front end of the piston rod which are designated to press the ends of the resilient gripping elements in the direction towards the housing when the piston rod is fully retracted, allowing the removal of the cartridge from the cartridge gun.

Cartridge pistol with a cartridge holder

The invention is a pressurized gas providing and gas pressure regulating device. The invention is a container with an over pressurized second chamber of pressurized gas that can be released to the exterior of the container when a valve that is integrally connected to a piston that along with a first cylinder forms a first chamber that is filled with a comparably less over pressurized gas that pushes the valve open when the gas pressure outside of the container is too low, thereby permitting the over pressurized second chamber to fluidly connect via the valve and thereby increase the pressure outside the container, such as to a volume of gas located below a piston within a fluid dispenser, the first and second chambers are shaped as cylinders and the first cylinder fits within the second chamber.
