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.

Abstract: A fastener consisting essentially of a male member and a female member having a bore engageable over the male member, and a threaded member threadable in a partially threaded bore having an axis substantially parallel to the longitudinal axis of the male member, a portion of the partially threaded bore, for example one half, being threaded and formed in the male member and another portion being unthreaded and formed in the female member. Rotating the threaded member in one direction causes the female member to be displaced longitudinally relative to the male member to a desired position. The present invention can be used as an alternative to nuts and bolts for mechanical assemblies, by providing the male member with an enlarged head, or it may be used for mounting arms, pulleys, gears, cams and the like on a shaft.
