摘要:
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.
摘要:
A dispensing valve to be used with a bottle of fluent imaging material. The valve is so structured that it can be assembled more rapidly and easily than existing dispensing valves used for the same purpose. The new valve holds the valve plug and the biasing spring in proper relative position on the actuating spindle without the use of retaining rings and does not require a jig for its assembly.
