<p>The present invention concerns a collar (4) for high-pressure bottles (and the process for its implementation), characterized in that it is composed of two elements attachable to each other, which can be integrated in the mass (3) of the container itself, formed of composite material, metal alloy, synthetic material, resins and reinforcement fibers. The internal - extractable - element (4.2) of the nozzle (4) presents in its internal part a hexagonal through hole (9), whereas the upper part presents a thread for fixation of a valve or tap; on the upper external part there is located a thread for coupling with the external element (4.9), whereas on the lower part there is an annular seat for receiving a seal (5) in direct contact with the core (2). A similar seal (5) is provided on the external element (4.9). Between the two elements (4.2) and (4.9) - on the lower part -, the terminal of the core (2) is fixed: the assembly is then enclosed on its exterior in a plurality of wrapping layers made of reinforcement fibers and synthetic resins.</p> |
