Description

Konservenglasöffner vermittels radial beweglicher Messer. Die bekannten Öffner für Konservengläser haben den Nachteil, daß die Öffner selbst bei fest verschlossenen Gläsern versagen oder den Deckel oder Verschlußring der zu öffnenden Gefäße beschädigen, und zwar dadurch, daß die Messer gar nicht oder nur in der Schneiderichtung zwangsweise geführt werden, während die Führung quer zur Schneiderichtung fehlt und somit die zwischen Glas und Deckelrand geführten Messer sich ecken.Can opener by means of radially movable knives. The known Openers for canning jars have the disadvantage that the openers even when they are tightly closed Jars fail or damage the lid or locking ring of the containers to be opened, namely by the fact that the knife does not compulsorily or only in the cutting direction be performed while the guide is missing transversely to the cutting direction and thus the between the glass and the edge of the lid.

Diesem Nachteil soll durch den Öffner nach vorliegender Erfindung abgeholfen werden. Der Öffner besteht im wesentlichen aus einer Platte, welche in bekannter Weise mit mehreren Schlitzen versehen ist, in welchen mehrere Messer zwangsweise radial geführt werden. Diese Messer sind mit Führungsstiften versehen, welche in exzentrisch verlaufende Schlitze einer zweiten Platte greifen. Beide Platten sind mit Griffen versehen und um eine gemeinsame Achse drehbar. Durch Gegeneinanderbewegen der Griffe werden die Messer infolge der exzentrischen Schlitzführung in radialer Richtung verschoben ; hierdurch wird der Öffner einesteils in einem Arbeitsgang für die betreffende Größe eingestellt und gleichzeitig das Konservenglas durch Einführen der Messer zwischen Deckel und Verschlußring geöffnet. Zum Halten von Konservendosen sind derartige Platten mit bogenförmigen und exzentrisch verlaufenden Schlitzen 'bekannt.This disadvantage is intended by the opener according to the present invention be remedied. The opener consists essentially of a plate, which is in known way is provided with several slots in which several knives forcibly be guided radially. These knives are provided with guide pins which are inserted in grip eccentric slots of a second plate. Both panels are provided with handles and rotatable about a common axis. By moving towards each other of the handles, the knives become radial as a result of the eccentric slot guide Shifted direction; This means that the opener is on the one hand in one operation adjusted for the size in question and at the same time inserting the canning jar the knife is opened between the cover and the locking ring. For holding food cans are such plates with arcuate and eccentrically extending slots 'known.

Mit Hilfe dieses Mittels ist ein Öffnen des Glases unter Anwendung nur ganz geringer Kraft möglich: weder Glas noch Deckel oder Gummiring werden beschädigt, da die Messer in jeder Richtung zwangsweise geführt werden und sich demzufolge nicht ecken können. Der Deckel wird beim Öffnen zwischen den Messern aufgefangen.With the help of this means an opening of the glass is under application only very little force possible: neither the glass nor the lid or the rubber ring will be damaged, since the knives are forcibly guided in every direction and therefore not can corners. The lid is caught between the knives when it is opened.

Die Zeichnung Fig. i zeigt den Öffner in der Aufsicht von unten. a ist eine Platte aus geeignetem Stoff mit Griff b, c sind die Führungsschienen der Schlitze d, e sind die Messer mit der angebogenen Schneide ei, f sind die Führungszapfen, g ein Bolzen, welcher die gemeinsame Achse bildet und die Platten zusammenhält, h ist die zweite Platte mit den exzentrisch verlaufenden- Schlitzen k. Fig. a zeigt diese beispielsweise Ausführungsform im Schnitt A-B.The drawing Fig. I shows the opener in a plan view from below. a is a plate made of suitable material with a handle b, c are the guide rails of the slots d, e are the knives with the bent cutting edge ei, f are the guide pins, g is a bolt that forms the common axis and holds the plates together, h is the second plate with the eccentrically extending slots k. Fig. A shows this example embodiment in section AB.
