ABSTRACT:
The invention relates to a dispensing valve cap assembly for fluid materials under pressure with a warranty seal. The valve includes a body made of plastic material attachable within the inlet of a container for the material to be dispensed and the cap is passed through by a conduit opening at one end thereof into a seat for accommodating the free end of the valve stem, and at the other end thereof into an outlet nozzle for the material to be dispensed. The cap has integral therewith via breakable finger-like elements a skirt extending to the valve, and the valve body has projecting therefrom an inner cylindrical wall adjacent to the skirt and a tubular wall defining a cylindrical cavity with the valve stem and having at least one inward projecting rib. The stem accommodating seat is defined by an extension projecting from the cap and extending within the cylindrical cavity, the outer surface of the extension having at least one projecting portion thereof interfering with the rib to prevent the cap from being removed off of the stem.
