Description
Schutzkappe für die Deckelventile von Konservengefäßen. Es ist bekannt, die Lufteinlaßventile im Deckel von Vakuumkonservengefäßen mit einer Schutzkappe zu versehen, so daß sie vor unbeabsichtigtem Druck und Stoß bewahrt bleiben. Diese Schutzkappen werden nachträglich aufgesetzt, so daß besondere Vorkehrungen zu treffen sind, die das Lüften des Ventils unter dem beim Kochen in dem Konservengefäß auftretenden Überdruck begrenzen.Protective cap for the lid valves of canning jars. It is known, the air inlet valves in the lids of vacuum canning jars with a protective cap to be provided so that they are protected from unintentional pressure and impact. These Protective caps are subsequently put on so that special precautions have to be taken are the venting of the valve under the occurring when cooking in the canning vessel Limit overpressure.
Gemäß :der Erfindung bildet die Schutzkappe einen Teil des Ventilgehäuses, in dem der als Ventilkörper dienende Stöpsel auf und ab zu spielen vermag. Dabei ist die Kappe außer zum Schutz des Ventils und zur Hubbegrenzung des Ventilkörpers auch für das Entweichen der aus dem Konservengefäß abgeblasenen Luft eingerichtet. Zu diesem Zweck ist am unteren Rande ,der Schutzkappe eine Krempe angeordnet, die in die .das Lufteinlaßventil aufweisende Vertiefung des Deckels paßt und @in .dieser Vertiefung durch einen Bajoniettverschluß leicht lösbar befestigt wind. Zwischen der Krempe und der das Lufteinlaßventil aufweisenden Vertiefung des Deckels verbleibt ein Spalt, der die beim Kochen des Gefäßinhalts infolge des inneren Überdruckes durch das geöffnete Ventil abgeblasene Luft entweichen läßt.According to: the invention, the protective cap forms part of the valve housing, in which the plug serving as the valve body is able to play up and down. Included is the cap except to protect the valve and to limit the stroke of the valve body also set up for the escape of the air blown from the canning jar. For this purpose, a brim is arranged on the lower edge of the protective cap, which in the .das air inlet valve having recess of the lid fits and @in .dieser Indentation easily detachable attached by a bayonet fastener. Between the rim and the recess of the cover which has the air inlet valve remains a gap that forms when the contents of the vessel boil due to the internal overpressure allows air blown off through the open valve to escape.
Die Schutzkappe kann als Massenartikel einfach und billig hergestellt werden, In der Zeichnung ist die Schutzkappe in einer Ausführungsform zur Darstellung gebracht.The protective cap can be mass-produced simply and cheaply In the drawing, the protective cap is in one embodiment for illustration brought.
Abb. i zeigt die Schutzkappe in Draufsicht bzw. Seitenansicht; Ahb. 2 .zeigt das Lufteinlaßventil in einem zur Aufnahme der Schutzkappe nach Abb. i eingerichteten Deckel; Abb. 3 veranschaulicht die Schutzkappe in der Gebrauchsstellung.Fig. I shows the protective cap in plan view and side view; Ahb. 2 .shows the air inlet valve in one for receiving the protective cap according to Fig. I decorated lid; Fig. 3 illustrates the protective cap in the position of use.
Die Schutzkappe besteht aus einer oben geschlossenen Hülse a, die am Kopf bei c ringsherum geriffelt .ist und am unteren Rande eine Krempe besitzt, welche in die das Lufteinlaßventil aufweisende Vertiefung b des Deckels paßt, so daß ider Ventilkörper d mit Spielraum umschlossen wird.The protective cap consists of a sleeve closed at the top a, which the head at c is fluted all around and has a brim on the lower edge, which fits into the recess b of the lid having the air inlet valve, so that ider valve body d is enclosed with clearance.
Die Befestigung der Schutzkappe am Deckel erfolgt durch einen Bajonettverschluß. Indem Ausführungsbeispiel weißt die Krempe der Schutzkappe an zwei einander diametral gegenüberliegenden Stellen Ausschnitte f auf, die mit Nasen g am oberen Rande,der Vertiefung b des Deckels zusammenwirken. -Nachdem die Schutzkappe in die Vertiefung b so eingesetzt ist, daß die Nasen g durch die Randausschnitte f treten, ist mittels des geriffelten Kopfes c eine Drehung der Kappe herbeizuführen, durch welche diese fest am Deckel gesichert wird, dabei aber .zwischen der Vertiefung b und der Krempe einen Spalt für das Entweichen von Luft offen läßt. Die Schutzkappe bildet in ihrer Gebrauchsstellung einen Teil des Ventilgehäuses, in dem der als Ventilkörper dienende - Stöpsel d auf und ab zu spielen vermag.The protective cap is attached to the lid by means of a bayonet lock. In the exemplary embodiment, the rim of the protective cap knows two diametrically opposite one another opposite places cutouts f on, those with noses g on the upper edge, the Cooperate recess b of the lid. -After that, put the protective cap into the recess b is inserted so that the lugs g pass through the edge cutouts f is by means of of the corrugated head c to bring about a rotation of the cap, through which this is firmly secured on the lid, but .between the recess b and the brim leaves a gap open for air to escape. The protective cap forms in their Position of use a part of the valve housing in which the valve body is used - Able to play plug d up and down.
Zum leichten Lösen des Deckels von dem Konservengefäß ist die Schutzkappe abzunehmen, damit der als Ventilkörper dienende Stöpsel d zugängig wird und für den inneren und äußeren Druckausgleich gelüftet werden kann.The protective cap is used to easily detach the lid from the canning jar to remove so that serving as the valve body plug d is accessible and for the internal and external pressure equalization can be vented.
