Abstract
A spring actuated pump device is mounted on a container for fluid, the device including a pump chamber into which fluid from the container can flow, the spring forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a finger actuated discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable captive nut being swivelly mounted on the container against axial movement with respect thereto, the nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially in response to rotation of the nut relative to the container and cylinder structure to compress the spring and store additional fluid pressurizing energy therein.
