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 an aperture for placing the interior of the container in communication with the ambient and, a rotatable valve body being 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 in a second position of the valve body. The valve body is directly actuatable by means of a lever or, in the alternative, by means of a slide or a rotatable collar. 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 for defining a non-recessed surface permitting to keep clean the edges of the 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.
