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.
