Abstract
A pumping device for removing liquid from a container and dispensing it in the form of a spray includes a pump attached to the upper end of a container. A pump body is engaged in the container and a piston is movable in the container and is provided with a hollow rod projecting outside of the pump. A cylindrical cap is attachable to the container and has a pivoting actuating and dispensing element provided with a dispensing nozzle communicating through a passage with a cylindrical sheath projecting inside the actuating element. The free end of the hollow rod of the pump piston engages the sheath, and the hollow rod is flexible over part of its length as measured from its free end.
