Description

Sposób zamykania butelek lub podobnych pojemników przez zakladanie kapsli Przedmiotem wynalazku jest sposób zamykania butelek lub podobnych pojemników przez zaklada¬ nie kapsli majacej gwintowy kolpak zaopatrzony w pierscien zabezpieczajacy przed otwieraniem sie, który przy pierwszym otwarciu butelki odrywa sie od kolpaka.W znanych tego rodzaju zamknieciach do butelek lub podobnych pojemników kolpak wykonany jest z blachy formowanej na zimno, szczególnie z alu¬ minium. Pierscien zabezpieczajacy rolowany jest równiez na zimno. Zamkniecia wytwarzane z blachy maja róznorakie wady.Termoplastyczne tworzywa sztuczne nie nadaja sie do formowania na zimno. Pólfabrykat pierscie¬ nia zabezpieczajacego musi skutkiem tego byc naj¬ pierw w dostatecznym stopniu podgrzany, zanim moze byc rolowany. Naprezenia jakie przy tej ope¬ racji wystepuja w miekkim, ogrzanym tworzywie przewaznie powoduja znaczne odksztalcenia piers¬ cienia zabezpieczajacego.Celem wynalazku jest wyeliminowanie wad zna¬ nych rozwiazan tego typu. Sposób wedlug wynalaz¬ ku polega na tym, ze na szyjke pojemnika naklada sie pólprodukt kolpaka z twardego tworzywa termo¬ plastycznego z pierscieniem zabezpieczajacym, któ¬ ry pomiedzy linia zerwania a obrzezem ma czesc górna o grubszej sciance i czesc dolna o cienszej sciance, po czym ksztaltuje sie na szyjce pojemnika czesc dolna pierscienia zabezpieczajacego za pomo¬ ca nacisku mechanicznego i doprowadzania ciepla, 10 15 20 25 30 przy czym w czasie doprowadzania ciepla ciagle sprawdza sie stan uplastycznienia dolnej czesci pierscienia zabezpieczajacego i natychmiast po stwierdzeniu dostatecznej plastycznosci poddaje sie ja naciskowi mechanicznemu, a doplyw ciepla prze¬ rywa sie przed doprowadzeniem górnej czesci piers¬ cienia zabezpieczajacego do stanu plastycznego.Pierscien zabezpieczajacy ma czesc górna o scian¬ ce grubszej i czesc dolna ciensza, zatem mozna bez zadnych trudnosci poddac czesc ciensza formowa¬ niu przy jeidnoczesniym zachowaniu twardej kon¬ systencji oraz niezmienionego ksztaltu i stabilnosci czesci grubszej.Podczas doprowadzania ciepla, stan zmiekczenia cienszej czesci pierscienia zabezpieczajacego podle¬ ga ciaglemu sprawdzaniu i niezwlocznie przy osia¬ gnieciu wystarczajacego stopnia plastycznosci zosta- wywolany nacisk formujacy i najpózniej w tym samym momencie musi byc odciety doplyw ciepla lub przynajmniej tak silnie zredukowany, aby tem¬ peratura warstwy materialu podlegajacej formo¬ waniu wiecej nie wzrastala. W tym przypadku naj¬ prosciej jest tak postepowac, by ksztaltowana cien¬ sza czesc pierscienia tuz przed jej uplastycznieniem, podczas odprowadzania ciepla, byla nieprzerwanie poddawana dzialaniu pelnego nacisku formujacego, tak aby nacisk ten w momencie osiagniecia wy¬ starczajacego uplastycznienia mógl natychmiast po¬ dzialac i spowodowac natychmiastowe uformowa¬ nie. 7264572649 6 Kolpaki uwidocznione na fig. 1, 2, 3, 6 sa wszystkie wyposazone w gwint wewnetrzny. Sa one stosowa¬ ne równiez w stanie niegwintowanym. Te ostatnie wraz z juz'istniejacym zamknieciem pojemnika, na przyklad korkiem lub zwykla kapsla z nakretka, tworza wlasciwe zamkniecie, przy czym sa one za¬ mocowane wraz z ich pierscieniem zabezpieczaja¬ cym przez kolnierz na szyjce pojemnika.Gladkie pólprodukty kolpaków, przy tej samej operacji formowania ich pierscieni zabezpieczaja¬ cych, mozna równiez wyposazyc w gwint do nakre¬ cania na gwint pojemnika i wtedy, po odlaczeniu pierscienia, stanowia one normalne kapsle. PL PLMethod for closing bottles or similar containers by attaching caps The present invention relates to a method for closing bottles or the like by fitting a cap having a threaded cap provided with an anti-opening ring which breaks away from the cap when the bottle is first opened. bottles or the like, the colpak is made of cold-formed sheet metal, especially aluminum. The securing ring is also rolled cold. Closures made of sheet metal have various disadvantages. Thermoplastic plastics are not suitable for cold forming. The lock-ring blank therefore must first be sufficiently heated before it can be rolled. The stresses that occur in the soft, heated material during this operation usually cause significant deformation of the securing ring. The object of the invention is to eliminate the drawbacks of known solutions of this type. The method according to the invention consists in that the neck of the container is overlaid with a half-product of a hard thermoplastic material with a securing ring, which has an upper part with a thicker wall and a lower part with a thinner wall between the rupture line and the rim, and then the lower part of the securing ring is shaped on the neck of the container by means of mechanical pressure and the application of heat, 10 15 20 25 30, while the lower part of the securing ring is constantly plasticized during the application of heat and immediately subjected to a mechanical pressure when sufficient plasticity is found until the heat supply is interrupted before the upper part of the securing ring is made plastic. The securing ring has a thicker wall upper part and a thinner lower part, so that the thinner part can be molded without any difficulty, while keeping it hard. consistency and unchanged When applying heat, the softness of the thinner part of the securing ring is constantly checked and, as soon as a sufficient degree of plasticity has been achieved, the forming pressure is applied and at the very same time the heat input must be cut or at least so strongly reduced so that the temperature of the layer of material to be formed does not increase any more. In this case, the easiest way is to ensure that the formed thinner part of the ring, just before its plasticization, is continuously subjected to full forming pressure during heat dissipation, so that this pressure, when sufficient plasticization is achieved, can act immediately. and cause immediate formation. 7264572649 6 The caps shown in Figures 1, 2, 3, 6 are all fitted with an internal thread. They are also used unthreaded. The latter, together with the already existing closure of the container, for example a stopper or a simple cap with a screw cap, form the correct closure, and they are fastened with their securing ring through a flange on the neck of the container. operation of forming their securing rings, they may also be provided with a thread for screwing onto the thread of the container, and then, after the ring has been removed, they constitute normal caps.
