Description
Wiederverwendbarer kochf' t::@ieschluß für Konservendosen Die Erfindung betrifft einen wiederverwendbaren kochfesten Verschluß für Konservendosen, bei dem Deckel und Dosenflansch unter Zwischenschaltung eines Dichtungsringes mittels einer starren Ringzwinge U-förmigen Querschnitts zusammengeschlossen werden. Bekannt ist es, solche Ringzwingen in zwei Halbringzwingen zu teilen und beide durch ein zangenartiges Werkzeug von beiden Seiten herauf den Deckel- und Dosenflansch aufzuschieben.Reusable boilers The invention relates to a reusable boil-proof closure for food cans in which Lid and can flange with the interposition of a sealing ring by means of a rigid ring clamp U-shaped cross-section are joined together. Is known it is to divide such ring clamps into two half-ring clamps and both with a pair of pliers To push the tool from both sides up the lid and can flange.
Von Hand aus sind diese Zwingen aber schwer aufbringbar; weil die auf einmal aufzuschiebende Bogenlänge zu groß ist. Diese Schwierigkeit soll gemäß der Erfindung dadurch behoben werden, daß die Ringzwinge aus mehreren (mindestens drei) Ringteilen besteht, welche unter Zusammenpressen des dazwischen liegenden Gummiringes nacheinander aufgeschoben werden. Ist der Querschnitt des Gummiringes in an sich bekannter Weise quadratisch gewählt, so kommt in den Dichtungsring eine genügende Elastizität hinein, um eine kochfeste Anlage des Gummiringes an allen vier Begrenzungsflächen des Ringquerschnittes zu gewährleisten, während die Unterteilung der Ringzwinge in drei, vier oder mehr Teile infolge ihrer kurzen Bogenlänge ein Aufbringen von Hand unter gleichzeitigem starkem Zusammenpressen - des Gummiringes auf die Teilstrecke ermöglicht. Ebenso ist auch das Öffnen des Dosenverschlusses ohne besonderes Werkzeug durch seitliches Abdrücken der Ringzwingenteile nach außen erleichtert, während andererseits, wie die Erfahrung bewiesen hat, der Verschluß eine unbegrenzte kochdruckfeste Dichtung gewährleistet. Die Zeichnung zeigt in vergrößertem Maßstab einen Teilquerschnitt von Dosen- und Deckelrand.However, these clamps are difficult to apply by hand; because the arc length to be postponed at once is too great. This difficulty should according to the invention can be remedied in that the ring clamp consists of several (at least three) ring parts, which under compression of the intermediate Rubber ring are pushed on one after the other. Is the cross section of the rubber ring chosen square in a manner known per se, one comes into the sealing ring Sufficient elasticity in order to ensure that the rubber ring fits all boil-proof four boundary surfaces to ensure the ring cross-section while the subdivision the ring ferrule into three, four or more parts due to its short arc length Applying by hand with simultaneous strong compression - the rubber ring on the partial route. The same is also true for opening the can closure without any special tools by pressing the ring clamp parts outwards from the side relieved, while on the other hand, as experience has shown, the closure an unlimited pressure-resistant seal guaranteed. The drawing shows in enlarged Scale a partial cross-section of the can and lid edge.
Zwischen dem Randwulst a1 der Dose a und dem Randwulste bi des Deckels b ist ein bei Dosen mit U-förmigem Verschlußband und gerollten Flanschen schon verwendeter, im Querschnitt ungefähr quadratischer Gummiring c eingelegt, und von der Außenseite her sind ringsum nach der Erfindung mindestens drei Ringzwingenteile von U-förmigem Querschnitt d übergeschoben, die hierbei mittels der Ringwulsten keilförmig nach beiden Seiten den Gummiring c so weit zusammendrücken, daß er sich allseitig fest und dichtend an die vier Begrenzungsflächen legt, ohne daß er in der Mitte bis über die Grenze seiner Elastizität zusammengedrückt wird. Zwischen den unterteilten Ringzwingen ist je ein kurzer Spalt vorhanden. Bei großen Dosen kann die Ringzwinge auch in mehr als drei Teile aufgeteilt werden.Between the edge bead a1 of the can a and the edge bead bi of the lid b is already used for cans with a U-shaped sealing tape and rolled flanges, in cross-section approximately square rubber ring c inserted, and from the outside forth are all around according to the invention at least three ring ferrule parts of U-shaped Cross-section d pushed over, which in this case is wedge-shaped by means of the annular beads Press the rubber ring c together on both sides so that it is tight on all sides and places it tightly on the four boundary surfaces without it being in the middle to over the limit of its elasticity is compressed. Between the divided ring clamps there is a short gap in each case. With large doses, the ring clamp can also be used in more than three parts are split.
