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.

Abstract: 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.

Abstract: Pump that can be applied on a container and manually operable to deliver or dispense a liquid in an atomized form. The pump comprises a hollow stem for liquid delivery or dispensing, on which a sealing gasket is mounted and downward urged by a spring. A groove communicating through holes with the cavity of the stem is provided on the lower end of the latter. The gasket, normally sealing on the stem below said groove, when upward moved upon operation of the pump, has its lower edge suddenly bent inwardly of the groove, when arriving thereat, thus suddenly and completely communicating the passage of the pressure liquid to said holes of the stem.
