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. Although the valved closure of the invention is particularly well-suited for plastic or pasty material being dispensed, its use is not so limited and it is as effective as a means for dispensing liquid or powder materials.
