CHUCK VALVE DISPENSING MEANS ABSTRACT OF THE INVENTION A dispensing valve and nozzle combination for dispensing cartridges filled with viscous material such as caulking, sealant or glue. The valve and nozzle comprise a substantially cylin- drical cap terminating in a conical nozzle and a hollow sub- stantially cylindrical valve body terminating in a plurality of integral segments nested together within the conical nozzle of the cap. The segments superficially resemble the segments within a common drill chuck and open and close to provide a sealable passage for the dispensed material. The opening of the segments as the valve is opened permits relatively unimpeded straight through flow of very viscous material, nevertheless permitting the valve to be sealingly closed with little or no dispensable material clinging to the valve nozzle or exposed to the air. The valve cap and nozzle is trimmable on the bias to permit a bead to be put down in the normal manner. The bias trim or opening size of the nozzle can be selected within limits for a large or small bead and the valve is adjustable between the closed position and the trimmed open position.
