Abstract: A valved closure for a container holding plastic or pasty material and having an opening generally in the form of a neck for dispensing the material from the container. The valved closure is permanently or, in the alternative, removably mounted over the neck of the container. The valved closure consists of a hollow housing with a dispensing aperture for placing the interior of the container in communication with the ambient and a rotatable valve body disposed proximate the aperture such as to obturate the aperture in a first position. The valve body has a passageway placing the interior of the housing in communication with the housing aperture by rotation to a second position. The valve body is directly actuatable by means of a lever. The housing dispensing aperture has at least one chamfered side forming a sharp cutting edge for a ribbon of pasty material being dispensed from the container and the periphery of the valve body projects slightly beyond the edges of the dispensing aperture.
