Abstract
The valve includes a valve body formed onto a lid of a container, a closure member which is located in the valve body and a spiral spring which presses the closure member into the valve body so as to keep the valve closed. A first sealing section is formed on a section of the closure member and cooperates with a valve seat in the valve body. A second sealing section is formed on the valve body and cooperates with a part of a spray gun or similar device, into which the valve body section is inserted in order to prevent a leaking or fluid at that point. The valve does not need any sealing members made of elastomeric materials or rubber. In this way, deterioration of such sealing members, which is caused by the fluid and leads to loss of sealing capability, is avoided. Containers which are equipped with such valves can be stored in any arbitrary position.
