Abstract

The glass tankard has silvered, double walls, like a Dewar flask. This improves insulation of the contents.

Description

Insbesondere in der warmen Jahreszeit ist die Erwärmung eines gekühlten Getränks unerwünscht, da die Erwärmung mitunter den Geschmack des Getränks beeinträchtigt, aber auch den Trinkgenuss. Besonders betroffen sind hiervon die großen 1 l Trinkgefäße (bayerischer Maßkrug), da für das Leeren dieses großen Gefäßes mehr Zeit beansprucht wird und der Wärmeaustauschprozess entsprechend schneller abläuft.Especially in the warm season is the warming one chilled drink undesirable, because the warming sometimes the taste of the drink impaired but also the pleasure of drinking. The large 1 l are particularly affected Drinking vessels (Bavarian Maßkrug) there for that Emptying this big Vessel more It takes time and the heat exchange process runs correspondingly faster.

Ziel der vorliegenden Erfindung ist es daher, Gebrauchstrinkgefäße mit einem effizienten Thermoschutz zu versehen, damit das ausgeschenkte Getränk während der gesamten Trinkzeit keine oder nahezu keine Umgebungswärme aufnimmt. Aufgrund der Gesetzmäßigkeiten der Lehre von der Wärme- und Stoffübertragung kann diese Aufgabe vorzugsweise ein evakuiertes Doppelwandgefäß leisten, das zur Verhinderung der Wärmestrahlung auch noch verspiegelt ausgeführt sein kann, um auch den Wärmedurchgang der Strahlung zu minimieren.The aim of the present invention is it, therefore, use drinking vessels with a to provide efficient thermal protection so that the drink served during the takes up almost no ambient heat during the entire drinking period. Because of the laws the teaching of heat and Mass transfer can perform this task preferably an evacuated double wall vessel, that to prevent heat radiation also mirrored can also be to heat transfer to minimize the radiation.

Diese an sich bekannte Erfindung ist als sog. DEWAR Gefäß bekannt und findet seine Anwendung u.a. in Behältern für flüssigen Stickstoff, aber auch bei einfachen Haushaltsthermoskannen. Zielsetzung der Erfindung ist es, diesen an sich bekannten Thermoschutz auf offenen Gebrauchstrinkgefäßen anzuwenden.This invention known per se is known as a so-called DEWAR container and finds its application i.a. in containers for liquid nitrogen, but also in simple household thermos. The aim of the invention is it to apply this known thermal protection to open drinking vessels.
