Description
Einrichtung zum Öffnen von Blechdosen. Bei den bekannten Einrichtungen zum Öffnen von Blechdosen dient ein seitlich im Innern der Dose gelagerter Riegel, Hebel o. dgl., welcher durch Hochschieben ein Öffnen des Deckels bewirken soll. Hierbei stößt aber der Riegel o. dgl, seitlich vom Deckelrand gegen die Deckelunterseite, wobei der Deckel kantet und sich nur mit Gewalt vom Dosenunterteil abtreiben läßt. Da nun das Material des Deckels beim Pressen gerade beim Rand sehr beansprucht wird, so ist dieses beim Abtreiben des Deckels nicht widerstandsfähig genug und wird von dem Riegel, Hebel o. dgl. durchstoßen, ohne jedoch den Deckel abzuheben.Device for opening tin cans. With the known institutions A latch on the side inside the can is used to open tin cans, Lever or the like, which is supposed to open the lid by pushing it up. Here, however, the bolt or the like hits the side of the lid edge against the underside of the lid, whereby the lid is edging and can only be driven off the bottom part of the can with force. Since the material of the lid is now very stressed when pressing, especially at the edge, so this is not resistant enough when the cover is wiped off and is removed from the bolt, lever or the like. Pierce, but without lifting the cover.
Durch die Erfindung wird dieser Übelstand in wirksamster Weise beseitigt und besteht das Wesen derselben darin, daß der zum Öffnen der Dose .dienende Stift in einer in der Mitte des Dosenbodens angeordneten röhrenförmigen Hülse geführt wird, so daß derselbe in der Mitte den Deckel angreifen und ihn somit zentral ohne Kanten und Deformieren gleichmäßig abheben kann, wobei der Stift durch Aufsetzen auf einen Tisch o. dgl. den erforderlichen Druck gegen die Deckelunterseite ausübt. Die Hülse im Dosenboden kann auch pyramiden- oder kegelförmig sein, während der Stift von einer Feder an der Deckelunterseite anliegend gehalten wird, so daß bei Druck auf denselben der Deckel sich vom Dosenunterteil abhebt.This drawback is eliminated in the most effective manner by the invention and its essence consists in the fact that the pen used to open the box guided in a tubular sleeve arranged in the middle of the bottom of the can so that the same attack the lid in the middle and thus centrally without Edges and deforming can lift off evenly, the pin by touching down on a table or the like the required pressure against the underside of the lid exercises. The sleeve in the bottom of the can can also be pyramidal or conical, while the pin is held against the underside of the lid by a spring so that when pressure is applied to the same, the lid lifts off the lower part of the can.
In der Zeichnung sind drei beispielsweise Ausführungsformen der Erfindung dargestellt; es zeigt: Abb. i einen Querschnitt durch die erste Ausführungsform, Abb.2 einen gleichen Schnitt durch die zweite Ausführungsform, Abb.3 einen Schnitt durch die dritte Ausführungsform.In the drawing are three exemplary embodiments of the invention shown; It shows: Fig. i a cross section through the first embodiment, Fig.2 shows the same section through the second embodiment, Fig.3 shows a section by the third embodiment.
Der Boden a der Dose b ist gemäß Abb. i und 2 in seiner Mitte mit einem Loch c versehen, an welches sich die im Innern der Dose fortgeführte Röhre d anschließt. Diese Röhre d reicht bis zur Höhe des Dosenrandes, so daß beim Auffüllen der Dose b nichts über die Röhre d hinweg und durch diese nach außen ablaufen kann. Wird nun durch die Röhre d der durch den Deckel e der verschlossenen Dose.b ein Dorn o. dgl. gesteckt, bis dieser an die Unterseite des Deckels e anstößt, so genügt ein leichter und kurzer Druck mit dem Dorn gegen den Deckel e, worauf sich dieser gleichmäßig von der Dose abhebt. Da eine Beschädigung des Deckels hierbei vollständig ausgeschlossen ist, so kann dieser jedesmal nach Gebrauch der Dose wieder aufgesetzt werden, um den erforderlichen dichten Abschluß herbeizuführen.The bottom a of the can b is provided in its center with a hole c as shown in FIGS. I and 2, to which the tube d continued inside the can is connected. This tube d extends to the level of the can rim, so that when the can b is filled, nothing can run off over the tube d and through it to the outside. If a pin or the like is now inserted through the tube d through the lid e of the closed Dose.b until it hits the underside of the lid e, a light and short pressure with the pin against the lid e is sufficient, whereupon it stands out evenly from the can. Since damage to the lid is completely excluded, it can be put back on each time the can is used in order to achieve the required tight seal.
Die in Abb.2 dargestellte Ausführungsart wird noch durch einen in die Röhre d eingesetzten Dorn ergänzt, welcher durch eine Blattfeder g am Boden a der Dose b befestigt ist. Die Wirkungsweise beim Öffnen der Dose ist die gleiche wie beschrieben, wobei nach Aufheben des Druckes auf den Dorn f dieser durch die Feder g wieder in seine vorherige Stellung zurückgeführt wird. Das im Innern der Dose befindliche Dornende liegt in Ruhestellung dicht unterhalb der Unterseite des Deckels e. Es bleibt freigestellt, den Dorn t an seinem oberen Ende noch stempelartig auszubilden. Gemäß Abb. 3 wird beim Pressen der Dose h der Boden i von unten nach oben durchgepreßt, so daß der konische Kanal k gebildet wird, dessen obere Öffnung Z mit dem Dosenrand abschneidet. Der Vorgang des Abhebens des Deckels m ist der gleiche wie bei der Dose in Abb. i, indem ein Dorn durch den Kanal k bis zum Deckel geführt und durch Druck auf diesen der Deckel abgehoben wird.The embodiment shown in Fig.2 is supplemented by a mandrel inserted into the tube d, which is fastened to the bottom a of the can b by a leaf spring g. The mode of operation when the can is opened is the same as described, whereby after the pressure on the mandrel f is released, it is returned to its previous position by the spring g. The end of the mandrel located inside the can is in the rest position just below the underside of the lid e. It remains optional to design the mandrel t at its upper end in the manner of a stamp. According to Fig. 3, when pressing the can h, the bottom i is pressed through from bottom to top, so that the conical channel k is formed, the upper opening Z of which cuts off with the edge of the can. The process of lifting off the lid m is the same as for the can in Fig. I, in that a mandrel is passed through the channel k to the lid and the lid is lifted by applying pressure.
Es bleibt vorbehalten, bei besonders großen Dosen auch mehrere Bodendurchbrüche c, d oder k, l vorzusehen.We reserve the right to provide several bottom openings c, d or k, l for particularly large boxes.
