Abstract

Dispositivo per la chiusura dell'estremità di contenitori a forma di corpi tubolari o simili comprendente un ugello (9) di emissione di aria calda alimentata attraverso un condotto (1b) di alimentazione di aria calda in cui coassialmente a detto ugello è disposto un insieme di tubi (2, 5, 6) concentrici determinanti tra loro una pluralità di intercapedini (2b, 5b), e da ciò che all'estremità inferiore (2a) del più esterno (2) di detti tubi è reso solidale un corpo cavo (4) mantenuto a bassa temperatura mediante la ricircolazione di un liquido refrigerante attraverso dette intercapedini, detto corpo cavo (4) essendo inoltre attraversato dal più interno (6) di detti tubi concentrici per l'alimentazione di un gas inerte atto a disporsi all'interno del contenitore (8) tra il prodotto (7) e il corpo cavo (4), essendo inoltre previsti mezzi (11; 111) di centratura e cilindrificazione della parete laterale del corpo tubolare (8) da sigillare e condotti (13b, 11b,13a; 13b, 111b, 13a) per l'evacuazione, mediante aspirazione, dell'aria calda alimentata dal detto ugello.Device for closing the end of containers in the form of tubular bodies or the like comprising a hot air emission nozzle (9) fed through a hot air supply duct (1b) in which a set of concentric pipes (2, 5, 6) determining among them a plurality of cavities (2b, 5b), and from what at the lower end (2a) of the outermost (2) of said pipes a hollow body (4) is made integral ) maintained at a low temperature by the recirculation of a refrigerant liquid through said cavities, said hollow body (4) being also traversed by the innermost (6) of said concentric pipes for feeding an inert gas suitable to be disposed inside the container (8) between the product (7) and the hollow body (4), as well as means (11; 111) for centering and cylindering the side wall of the tubular body (8) to be sealed and conduits (13b, 11b, 13a ; 13b, 111b, 13a) p for the evacuation, by suction, of the hot air supplied by said nozzle.
