<p>The device comprises a body containing a pump adapted for pumping liquid from a container to an atomizer nozzle via a fluid passage conduit and a tube. An auxiliary conduit communicates the interior of the container to an outwardly open hole. A first valve is interposed between the tube and fluid passage conduit to intermittently close the end of the tube upon reciprocation of the pump plunger. A second valve is interposed between the container and the auxiliary conduit, for preventing fluid from passing through the latter upon the device being overturned.</p> |
