Abstract
Abstract A CONVERSION KIT FOR CONVERTING LIQUID EJECTOR PUMPS TO FIT ONTO CONTAINERS OF DIFFERENT SIZES. THE PUMP HAS A DIP TUBE SURROUNDED AT ITS UPPER END BY A COLLAR THAT HAS A LATERALLY PROJECTING FLANGE AT ITS LOWER END. THE VARIANT-SIZED CONTAINER CAP HAS A HOLE PASSING OVER THE FLANGE SO IT CAN SURROUND THE TUBULAR COLLAR. A RESILIENT SPLIT WASHER HAVING A CENTRAL OPENING LARGE ENOUGH TO PASS AROUND THE COLLAR BUT NOT OVER THE FLANGE HOLDS THE CAP ABOVE THE FLANGE. BELOW THE FLANGE THERE IS ANOTHER RESILIENT RETAINER RING PRESSED SNUGLY INTO THE CAP, AND SEALINGLY ENGAGES AROUND THE PERIPHERY OF THE LOWER FACE OF THE FLANGE. IT HAS A CONICAL DEPENDING GUIDE FOR THE DIP TUBE.
