Description

  

  Deckel zum luftdichten Verschliessen eines Gefässes mit verdicktem Rand,  insbesondere einer Konservendose.    Die Erfindung     betrifft    einen Deckel zum  luftdichten Verschliessen eines Gefässes mit  verdicktem Rand, insbesondere einer Kon  servendose.  



  Bisher wurden alte Konservendosen, wel  che von     neuem    benutzt werden sollten, durch  Maschinen abgeschnitten und dann durch       Verschlussmaschinen    wieder geschlossen. Bei  diesem Verfahren wird der Rauminhalt der  abgeschnittenen Konservendose     kleiner.    Im  Haushalt verfügt man über derartige Ab  schneide- und     Verschlussmaschinen    nicht, so  dass die     geöffneten    Konservendosen fortge  worfen werden müssen.  



  Gemäss der     Erfindung    ist zwecks luftdich  ten Abschlusses des Gefässes in einer Ring  nut des Deckelbodens ein     Gummiring        eir)ge-          legt    und der     lllantel    des Deckels     trägt-eine          Anzahl    von federnden, nach innen gebogenen       Lappen,    welche beim Aufsetzen des Deckels  unter den verdickten Rand des Gefässes fas  sen, zum Zwecke, den Deckel in seiner Lage  festzuhalten.    Um in jedem Falle ein sicheres Eingreifen  der Lappen zu gewährleisten, sind die Kan  ten der Lappen zweckmässig nach dem In  nern des Deckels zu umgebogen. Zwecks  Verstärkung können die Lappen eine oder  mehrere Rippen besitzen.

   Damit sich der  Deckel elastisch durch den beim Kochen ent  stehenden Druck nach aussen wölben kann,  weist der Deckelboden     vorteilhafterweise     einen ebenen Mittelteil, eine nach innen ge  drückte Sicke, einen     kegelstumpfförmigen    Teil  und eine nach aussen gebogene Sicke auf.  



  In der Zeichnung ist eine beispielsweise  Ausführungsform des neuen Deckels darge  stellt. Es zeigt       Fig.    1 eine Draufsicht auf den Deckel,       Fig.2    einen senkrechten Schnitt durch  den Deckel,       Fig.    3 eine vergrösserte     Perspektivansicht     eines Lappens,       Fig.    4 eine mit dem Deckel geschlossene  Konservendose,           Fig.        "5    eine vergrösserte     Perspektivansicht     eines mit einer Verstärkungsrippe     versehenen     Lappens.  



  In der Ausführungsform des Deckels nach       Fig.    1 und 2 besteht dessen Boden aus einem  ebenen Mittelteil 1, welcher durch eine nach  dem Deckelinnern hineingedrückte Sicke oder  Vertiefung 2 begrenzt wird. Die ringförmige  Vertiefung     2$gehtin    einen     kegelstumpfförmigen     Teil 3 über, der zweckmässig einen flachen  Absatz 4 besitzt. Der     kegelstumpfförmige     Teil 3 wird von einer ringförmigen, nach  aussen herausgedrückten Sicke oder Vertiefung  5 begrenzt, welche in den verhältnismässig  starken Teil 6 ausläuft. Diese Ausbildung  des Deckels ermöglicht, dass sich der Deckel  unter dem beim Kochen entstehenden Druck       auswölben    kann.  



  In einer ringförmigen Nut des Teils 6  liegt ein Gummiring 7 von ca. 3 bis 6 mm  Stärke. Der Mantel 8 des Deckels besitzt  eine Anzahl Lappen 9, welche ein wenig nach  dem Innern des Deckels gebogen sind und  unter den durch     Umbördelung    verdickten  Rand 10 der Konservendose fassen. Der Rand  der Konservendose wird also zwischen dem  nachgiebigen Gummiring 7 und den verschie  denen Lappen 9 fest eingeklemmt, wodurch  ein luftdichter Abschluss der Dose erzielt  wird. Um ein sicheres Festhalten durch die  Lappen 9 zu erreichen, besitzen diese nach  innen umgebogene     Kanten    11 und 12. Zwecks  Verstärkung können die Lappen, wie in     Fig:    5  dargestellt, eine oder mehrere Rippen. 13 auf  weisen.  



  Eingehende Versuche mit Konservendosen,  welche mit dem neuen Deckel verschlossen  wurden, haben ergeben, dass der Inhalt der  Dose praktisch steril bleibt, und dass man die  Dosen ohne weiteres kochen kann, ohne dass  der Deckel abspringt oder Luft zutritt.    Der Deckel gemäss der Erfindung kann  ferner zum Schliessen von Milchkannen, Blech  kanistern, Ölbehältern usw. verwendet wer  den.     -Überall    dort, wo ein luftdichtes Ver  schliessen von Gefässen gewünscht wird, kann  man sich eines Deckels gemäss der Erfindung  bedienen, wobei natürlich Voraussetzung ist,  dass Gefässöffnung und Deckel aufeinander  passen und das Gefäss einen verdickten Rand  aufweist.



  Lid for airtight sealing of a vessel with a thickened rim, especially a tin can. The invention relates to a lid for the airtight sealing of a vessel with a thickened edge, in particular a con serving jar.



  Up to now, old tin cans, which were supposed to be used again, were cut off by machines and then closed again by sealing machines. With this process, the volume of the cut can becomes smaller. In the household one does not have such cutting and sealing machines, so that the opened cans must be thrown away.



  According to the invention, for the purpose of airtight closure of the vessel, a rubber ring is placed in an annular groove in the bottom of the lid and the cover of the lid carries a number of resilient, inwardly bent tabs which, when the lid is placed, under the thickened edge of the Receptacle sen, for the purpose of holding the lid in place. In order to ensure that the tabs engage securely in any case, the edges of the tabs are appropriately bent after the inside of the lid. For the purpose of reinforcement, the flaps can have one or more ribs.

   So that the lid can elastically bulge outwards due to the pressure ent during cooking, the lid base advantageously has a flat central part, an inwardly pressed bead, a frustoconical part and an outwardly curved bead.



  In the drawing, an example embodiment of the new cover is Darge provides. 1 shows a top view of the lid, FIG. 2 shows a vertical section through the lid, FIG. 3 shows an enlarged perspective view of a tab, FIG. 4 shows a can closed with the lid, FIG. 5 shows an enlarged perspective view of one with a Reinforcing rib provided flap.



  In the embodiment of the cover according to FIGS. 1 and 2, the base of the cover consists of a flat central part 1 which is delimited by a bead or recess 2 pressed in towards the inside of the cover. The annular recess 2 $ merges into a frustoconical part 3, which expediently has a flat shoulder 4. The frustoconical part 3 is delimited by an annular, outwardly pushed out bead or depression 5, which ends in the relatively thick part 6. This design of the lid enables the lid to bulge out under the pressure generated during cooking.



  In an annular groove of the part 6 is a rubber ring 7 approximately 3 to 6 mm thick. The jacket 8 of the lid has a number of tabs 9 which are bent a little towards the inside of the lid and grasp under the edge 10 of the tin can which is thickened by flanging. The edge of the tin can is thus firmly clamped between the flexible rubber ring 7 and the various flaps 9, whereby an airtight seal of the can is achieved. In order to achieve a secure hold by the tabs 9, these have inwardly bent edges 11 and 12. For the purpose of reinforcement, the tabs can, as shown in FIG. 5, one or more ribs. 13 show.



  Extensive tests with food cans which have been closed with the new lid have shown that the contents of the can remain practically sterile and that the cans can be cooked without further ado without the lid cracking off or air entering. The lid according to the invention can also be used to close milk cans, sheet metal canisters, oil containers, etc. who the. -Wherever an airtight closure of vessels is desired, a lid according to the invention can be used, with the prerequisite, of course, that the vessel opening and lid fit one another and the vessel has a thickened edge.
