Abstract
A dispensing valve for use on an inverted bottle of fluent imaging material includes a valve cap which can be threaded to the neck of the bottle. A resilient valve plug is carried on a spindle which extends through an opening in the valve cap. A spring compressed between an enlargement on the spindle and a hub in the valve cap biases the valve plug outwardly into sealing engagement with a valve seat at the interior end of the valve cap. The valve is protected from inadvertent opening by a disc-like clip and an overcap. The clip, which has a diametral slot to accommodate the spindle, is held between an end of the spring and the spindle enlargement. The overcap provides a complete cover for the valve; it can be removed to expose the clip so that the clip can be manually removed to permit the valve to be opened.
