Description

Das Öffnen von Dosen ist oft mit Schwierigkeiten verbunden. Die Dosen müssen, um ihren Zweck zu erfüllen, luftdicht schließen, damit das Füllgut frisch erhalten bleibt. Diese Forderung aber ist nur durch gute konstruktive und fertigungstechnische Durchbildung von Ober- und Unterteil zu erreichen, und zwar derart, daß zwei leicht konisch geformte Zylinder übereinandergeschoben werden und durch Reibung aneinander haften. Diese Reibung muß nun überwunden werden, wenn man die Dose öffnen will. Opening cans is often difficult. The cans must, in order to fulfill their purpose, close airtight so that the product is fresh preserved. This requirement is only possible through good design and manufacturing To achieve through formation of upper and lower part, in such a way that two easily conically shaped cylinders are pushed one on top of the other and by friction against each other be liable. This friction must now be overcome if you want to open the can.

Es gibt nun einige Vorschläge zur Erleichterung des Öffnens. Im allgemeinen wird ein Messer genommen, mit der Klinge zwischen Ober- und Unterteil gefahren und auf diese Weise eine zwangsweise Trennung beider Teile erreicht. Die Folge davon ist eine Deformierung des abdichtenden Teiles und oft genug auch eine Verletzung der Hände. Ein anderer Vorschlag geht dahin, eine Öffnung durch Rollen zu erzwingen. Die unausbleibliche Folge ist, daß das Füllgut herausgedrückt wird und sogar herausfällt. There are now some suggestions to make opening easier. In general a knife is taken, moved with the blade between the upper and lower part and in this way a compulsory separation of both parts is achieved. The consequence of this is a deformation of the sealing part and often enough also an injury of the hands. Another suggestion is to force an opening by rolling. The inevitable consequence is that the filling material is pushed out and even falls out.

Einen wesentlichen Fortschritt brachte die Anbringung eines seitlichen Hebels am Deckelring, welcher auf den Begrenzungswulst des Unterteils drückt, dadurch das Oberteil, den sog. Deckel, verdrückt und einseitig abhebt. Diese Einrichtung gewährleistet jedoch nicht mehr eine einwandfreie Anlage der abdichtenden Flächen. The addition of a side panel was a major step forward Lever on the cover ring, which presses on the bead delimiting the lower part, thereby the upper part, the so-called cover, squeezes and lifts off on one side. This facility however, no longer guarantees that the sealing surfaces will fit perfectly.

Die vorliegende Erfindung soll nun eine völlig neuartig wirkende und technisch einwandfreie Lösung dieses Problems bringen. Konstruktiv wird nur der Deckel abgeändert. Er erhält am einfachsten am Ubergang vom Seitenring zur Deckelfläche einen Wulst angedrückt. Die Deckelfläche erhält eine wellenförmige, ringförmige Verformung und ist entweder nach oben leicht gewölbt bei Dosen mit vertieftem Boden oder kann auch flach bleiben mit Rücksicht auf die Verpackung. Durch diese wellenförmige Verformung erhält die Deckelfläche einen membranartigen Charakter und kann durch leichten Fingerdruck um ein oder mehrere Millimeter, je nach Größe der Dose, nach innen bewegt werden. Nach Fortfall des Fingerdruckes geht sie wieder in die Ausgangsstellung zurück, da das Material nicht über die Elastizitätsgrenze beansprucht wird. The present invention is now intended to be a completely novel one and bring a technically perfect solution to this problem. Only becomes constructive the lid modified. It is easiest to get at the transition from the side ring to the top surface pressed a bead. The cover surface is given a wavelike, annular shape Deformation and is either slightly curved upwards in the case of cans with a recessed bottom or can remain flat with consideration for the packaging. Through this wavy Deformation gives the cover surface a membrane-like character and can through light finger pressure by one or more millimeters, depending on the size of the can be moved inside. After the finger pressure has ceased, it returns to the starting position back, as the material is not stressed beyond the elastic limit.

In der Mitte dieser Membrane wird nun entweder eine leicht konisch ausgebildete steife zweite Deckelfläche oder eine flach ausgebildete, mit eingedrückten Versteifungsnuten versehene Scheibe angeschweißt, angelötet oder angenietet, wobei letztere in der Mitte eine eingedrückte Vertiefung aufweisen muß oder ein Zwischenstück verwendet werden muß. Dieser Sekundärdeckel ist so ausgebildet, daß er die Bewegung des Befestigungspunktes, welcher punkt-, flächen- oder ringförmig sein kann, in jeder Richtung mitmacht, die Bewegung des Membrandeckels aber nicht behindert.In the middle of this membrane there is either a slightly conical shape formed rigid second cover surface or a flat formed, with indented Washer provided with stiffening grooves is welded, soldered or riveted, whereby the latter must have a depressed depression in the middle or an intermediate piece must be used. This secondary cover is designed to allow the movement of the attachment point, which can be point, area or ring-shaped, in participates in any direction, but does not hinder the movement of the membrane cover.

Ist die Dose geschlossen, so sitzt der Sekundärdeckel allseitig auf den Rand des Unterteils am ganzen Umfang auf. Das Öffnen der Dose geht nun so vor sich: Man nimmt die geschlossene Dose so in eine Hand, daß der Daumen und der Mittelfinger den Deckel am Außenring festhalten und am Wulst des Deckels einen Widerstand finden. Das Unterteil wird dabei von der anderen Hand erfaßt. Drückt man nun mit dem Zeigefinger der ersten Hand auf die membranartige Deckelfläche, so wird das Unterteil durch den mitbewegten Sekundärdeckel ausgestoßen und von der zweiten Hand abgenommen. Eine Ausführung mit gewölbter Deckelfläche zeigt die Abbildung.If the can is closed, the secondary lid sits on all sides the edge of the lower part around the entire circumference. This is how you open the can yourself: You take the closed can in one hand so that your thumb and middle finger Hold the cover by the outer ring and find a resistance at the bead of the cover. The lower part is grasped by the other hand. Now press with your index finger the first hand on the membrane-like cover surface, the lower part is through ejected the secondary cover that was moved with it and removed it by the second hand. The illustration shows a version with a curved cover surface.
