Description

Einkochen von Konservengefäßen Es ist bekannt, den Deckel von Konservengläsern während des Einkochens mit flächenförmig drückenden Bügeln ,aufzupressen (vgl. beispielsweise die schweizerische Patentschrift 28354) ebenso hierzu auch Hauben und ähnliche Außenbügel zu verwenden. Dann ist es bekannt, Verschlußplättchen für Konservengefäße aus dünnen, wenig widerstandsfähigen Folien auf der ganzen Fläche durch widerstandsfähiges Material zu schützen (vgl. die britische Patentschrift 458 541, die französischen Patentschriften. 438 261, besonders Abb. 5, und 324 592 und die britische Patentschrift 207 764).Preserving canning jars It is known to use the lids of canning jars during the boiling process with flat pressing brackets (cf. for example Swiss Patent 28354) also covers hoods and similar outer brackets to use. Then it is known to make sealing plates for canning jars made of thin, less resistant foils on the whole surface due to resistant material to protect (see British patent specification 458 541, the French patents. 438 261, especially Fig. 5, and 324 592 and British patent specification 207 764).

Erfindungsgemäß wird das gefüllte Glas mit dem Deckel aus dünnem Blech oder Zellhaut luftdicht verschlossen. Dann wird der widerstandsfähige Überdeckel in seiner ganzen Fläche etwa -mit Hilfe eines seitlichen Spannringes auf den Deckel gepreßt, uns den Überdruck ,auf Deckel und Dichtung während des Einkochens voll aufzufangen, -und danach für weitere Verwendung abgenommen Abb. i zeigt einen Schnitt und teilweise Vorderansicht des Spannringes. Es sind: a Überdeckel, b Spannring, c Korkring im Gberdeckel, cl Blechdeckel, e Gummiring. Abb. 2 zeigt die Hälfte der Draufsicht auf Gberdeckel und Spannring mit schwenkbarem Schraubbolzen unfd Mutter im Anschlag.According to the invention, the filled glass with the lid is made of thin sheet metal or cell skin sealed airtight. Then the resilient overcap in its entire area - with the help of a side clamping ring on the lid pressed, us the overpressure, on the lid and seal during the boiling full and then removed for further use Fig. i shows a section and partial front view of the clamping ring. There are: a cover, b clamping ring, c cork ring in the cover, cl sheet metal cover, e rubber ring. Fig. 2 shows half of the Top view of cover and clamping ring with swiveling screw bolt and nut at the ready.

Der Vorteil gegen bisherige Verfahrenli,egt darin, daß für Deckel und Dichtung nur eine Materialstärke nötig ist, die lediglich für luftdichtes Verschließen bei Druckgleichheit innen und außen genügt, nicht aber dem zeitweiligen überdruck während des Einkochens a ler dem dauernden Unterdruck durch Vakuum nach dem Einkochen standzuhalten braucht, und darin, @daß die Dichtung durch Einkochüberdruck nicht gefährdet wird, .obgleich das Glas bis zum Rande gefüllt ist.The advantage over previous procedures lies in the fact that for covers and seal only a material thickness is necessary, which is only for airtight sealing If the pressure inside and outside is equal, it is sufficient, but not the temporary overpressure during the boiling process a ler the constant negative pressure caused by vacuum after boiling needs to withstand, and in the fact that @ the seal by boiling overpressure does not is endangered, although the glass is filled to the brim.

PATI:NTANSPRUCII: Einkochen von Konservengefäßen seit dünnen, gegen einen Überdruck reicht widerstandsfähigen Deckeln, vorwiegend aus dünnem Blech oder Zellhaut, gekennzeichnet durch die Anwendung eines überJekkels aus widerstandsfähigem Werkstoff, der in seiner ganzen Fläche, beIspIelsweise mit Hilfe eines seitlichen Spannringes, auf den Deckel gepreßt wird und nur während des Einkochens bei überdruck zur Anwendung kommt.PATI: NTANSPRUCII: Preserving canning vessels since thin, against overpressure is sufficient for resistant lids, predominantly made of thin sheet metal or Cell skin, characterized by the use of an overlay made of resistant Material that covers its entire surface, for example with the help of a lateral Clamping ring, is pressed onto the lid and only during the boiling process with excess pressure is used.
