Description

Konservendose mit Luftdruckverschluß und Tragring mit Dichtung für den Deckel. Die Erfindung betrifft eine Konservendose mit einem an dem Dosenrumpf befestigten Ring, -der einen Dichtungsring und darauf einen Dosendeckel trägt. Nach dem Füllen wird die Konservendose gekocht und durch die hierbei auftretende Luftverdünnung durch den äußeren Luftdruck verschlossen gehalten. Gegenüber bekannten Konservendosen weist die Erfindung den Vorteil auf, daß besondere Vorrichtungen zum Festhalten des Dosendeckels während des Kochens nicht notwendig sind. Ein weiterer Vorteil besteht anderseits auch noch darin, daß die Dose durch Abheben. des Deckels leicht geöffnet werden kann.Food can with air pressure seal and support ring with seal for the lid. The invention relates to a can with one on the can body attached ring, which carries a sealing ring and a can lid on it. To After filling, the can is boiled and the air dilution that occurs in this process kept closed by the external air pressure. Compared to known cans the invention has the advantage that special devices for holding of the can lid are not necessary during cooking. Another advantage on the other hand, there is also the fact that the can is lifted off. of the lid easily can be opened.

Die Zeichnung zeigt eine Konservendose von der Seite, teilweise geschnitten.The drawing shows a can from the side, partially cut.

Das obere Ende des Dosenrumpfes a ist in bekannter Weise mit einem Ring b versehen, der angebördelt oder angelötet sein kann. Dieser in das Innere der Dose herabgebogene Ring dient zur Aufn?Lhme des üblichen Dichtungsringes e. Gemäß der Erfindung ist der Ring b mit Vorsprüngen c versehen, die durch Herausdrücken des Bleches oder durch Auflöten von kleinen Metallkügelchen gebildet sein können. Diese Vorsprünge c ragen so weit nach innen, daß der eingesetzte Dosendeckel d beim Einsetzen an diesen Vorsprüngen c Widerstand findet. Der Rand des Deckels d federt beim weiteren Eindrücken über diese Vorsprünge c hinweg und wird dann durch diese auf dem Dichtungsrand so festgehalten, daß er beim Kochen der Dose nicht ,abgedrückt werden kann.The upper end of the can body a is in a known manner with a Ring b provided, which can be flanged or soldered. This in the interior The ring, which is bent down, is used to accommodate the usual sealing ring e. According to the invention, the ring b is provided with projections c, which can be pressed out the sheet or can be formed by soldering small metal balls. These projections c protrude so far inwardly that the can lid used d when Insertion at these projections c finds resistance. The edge of the lid d springs on further pressing over these projections c away and is then through this held on the sealing edge so that it is not pressed when cooking the can can be.

Beim Abkühlen der Dose wird der Deckel d durch den äußeren Luftdruck fest auf den Dichtungsring e gepreßt, so daß der Inhalt von der Außenluft steril abgeschlossen ist. Die beim Kochen austretende Luft verläßt die Dose zwischen Dosendeckeld und Dichtungsring e.When the can cools down, the lid becomes d due to the external air pressure firmly pressed onto the sealing ring e, so that the contents are sterile from the outside air is completed. The air escaping during cooking leaves the can between the can lid and sealing ring e.

Der aufgesetzte Dosendeckel ist seinerseits mit Vorsprüngen versehen, die das Erfassen des Deckels beim Abheben erleichtern, wenn der Druckluftverschluß wieder aufgehoben werden soll. Diese Vorsprünge können an dem Dosendeckel dadurch erzeugt sein, daß Kügelchen von Lötzinn darauf befestigt sind. Auch können diese Vorsprünge durch Ein-oder Ausbiegungen des Deckelbleches gebildet sein. Beispielsweise kann eine ringförmige Einziehung t vorgesehen sein, die beim Öffnen der Dose für einen beliebigen spitzen Gegenstand als Angriffspunkt dient, indem sich letzterer gegen die über der Einziehung entstandene Randwulst stützt.The attached can lid is in turn provided with projections, which make it easier to grasp the cover when it is lifted off when the compressed air seal should be canceled again. These projections can be on the can lid thereby be produced that globules of solder are attached thereon. You can also do this Projections can be formed by bending the cover plate in or out. For example an annular indentation t can be provided, which when opening the can for any sharp object serves as a point of attack by the latter against the bulge created over the retraction.
