Abstract
A valve for dispensing a fluid from a container and a dispensing apparatus with such a valve are proposed. The valve has a spring device for returning a valve element to a closed position, the spring device being integral with the valve element. The spring device has a contact area for contact with a counterface of a valve body, the contact area forming an elevation of an outer surface of the spring device. The spring device and the counterface are in point contact with each other in any position of the valve element. The materials of the contact area and the counterface are matched to each other in such a way that they slide silently on each other. A seal of the valve is made of polyethylene or a thermoplastic elastomer. The valve is preferably designed as a full plastic valve and is easily recyclable.
