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.

Valve and cap assembly for dispensing fluid materials under pressure

The invention relates to a pump applicable to containers holding a substance to be delivered or dispensed under pressure, which pump is manually operable. The pump includes a hollow stem movable within a hollow body, urged out of the latter by a spring and retained therein by a ring sealingly connectable or hookable on a ring nut which can be secured on the mouth or inlet member of a substance container. A seal of H-cross-section is mounted and movable on the stem and by its lips seals on the inner surface of the hollow body, on the outer surface of the stem, on a tubular extension projecting from the above mentioned ring, and respectively in either of two annular grooves presented by the stem or bodies associated therewith. On moving between such grooves during the movement of the stem, the seal closes or clears a channel through which the pressure substance can exit as previously sucked within the hollow body, which bears on the outward facing surface of an annular edge projecting from the ring nut. Thus, the same body of the pump can be applied on containers of different sizes, by merely changing its supporting and fastening ring nut on each container, and additionally the pump body cannot fall within the container, whenever pressure is applied on its stem.

Improvements in or relating to caps for containers, particularly aerosol containers, of the type comprising inner and outer skirt portions fast with each other by means of a top disc member, wherein the inner skirt member is seamable to the container through lugs and has a weakened zone which can be filled through rotation of a tab, which is integrating part of the cap and is joined at one end to the outer skirt member through a readily breakable lap.
