Description

Bei den bekannten Einmachgefäßen liegt der Deckel mit seiner ringförmigen Dichtfläche (oft mit Wulst) auf einer entsprechenden Dichtfläche des Gefäßrandes (oft mit Rille) auf. Zwischen beiden Flächen liegt ein Gummiring zum Abdichten. In the known canning jars, the lid is ring-shaped Sealing surface (often with a bulge) on a corresponding sealing surface on the edge of the vessel (often with a groove). There is a rubber ring between the two surfaces for sealing.

Zum Öffnen eines solchen verschlossenen Gefäßes muß man den Gummiring aus seiner normalen Lage so weit herausziehen, daß Luft eindringt. To open such a closed vessel you have to use the rubber ring pull it out of its normal position enough to allow air to enter.

Hierbei kommt es leicht vor, daß der Gummiring beschädigt wird oder sich nicht herausziehen läßt.It can easily happen that the rubber ring is damaged or cannot be pulled out.

Im letzteren Fall kommt es bei weiteren Öffnungsversuchen meist zu Beschädigungen des Gefäßes.In the latter case, further attempts to open it usually result Damage to the vessel.

Zur Vermeidung dieser Übelstände erhalten die Dichtflächen eine besondere Ausbildung in Form in sich zurücklaufender gerader Wendelfiäcleen a mit veränderlichem Steigungswinkel, die das Öffnen des Gefäßes nicht durch Herausziehen des Gummiringes, sondern durch Drehen des Deckels ermöglichen. Hierbei wird der Deckel auf Grund des Gesetzes der schiefen Ebene trotz des Schließdrucks der Außenluft ohne großen Kraftaufwand zwangsläufig nach oben bewegt, wodurch Lücken entstehen, in die Luft eindringen kann. To avoid these inconveniences, the sealing surfaces are given a special one Training in the form of receding straight Wendelfiäcleen a with variable Angle of inclination that prevents the vessel from being opened by pulling out the rubber ring, but enable it by turning the lid. Here, the lid is on the ground of the law of the inclined plane despite the closing pressure of the outside air without great Exertion of force inevitably moves upwards, creating gaps in the air can penetrate.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt. In the drawing, an embodiment of the invention is for example shown.

Abb. 1 ist die Seitenansicht des Gefäßes, Abb. 2 die Draufsicht, Abb. 3 ein Querschnitt nach der LinieA-A der Abb. 1, Abb. 4 eine Ansicht des abgewickelten Gefäßdeckels und -halses. Fig. 1 is the side view of the vessel, Fig. 2 is the top view, Fig. 3 is a cross-section along the line A-A of Fig. 1, Fig. 4 is a view of the developed Vessel lid and neck.
