Description

Die üblichen Isolierflaschen, unter dem Namen Thermosflaschen bekannt, besitzen an ihrem äußeren Flaschenkolben ein Kapillarzäpfchen als abstehenden Ansatz, um mit dessen Hilfe das Auspumpen des Zwischenwandhohlraums vornehmen zu können. Dieser Zapfenansatz ist sehr lästig, da er sowohl die Standfestigkeit der Flasche behindert, als auch selbst sehr gefährdet ist, so daß die Isolierflasche in einer eigens mit Rücksicht auf den Zapfenansatz gebauten Schutzhülle untergebracht werden muß, um überhaupt stehen zu können und bruchsicherer gemacht zu werden. Dieser Mangel verteuert die Therma-flasche wesentlich.The usual vacuum flasks, known as thermoses, have a capillary cone on their outer flask as a protruding attachment, in order to be able to use it to pump out the intermediate wall cavity. This spigot approach is very annoying as it both reduces the stability of the bottle handicapped, as well as itself is very endangered, so that the vacuum flask in a Specially built protective cover with due consideration for the peg attachment can be accommodated must in order to be able to stand at all and to be made more break-proof. This lack makes the Therma bottle much more expensive.

Die Erfindung beseitigt diese Mängel und damit auch die Schutzhülle dadurch, daß in dem nach innen gewölbten Boden des äußeren Flaschenkolbens an Stelle des Kapillarzäpfchens eine nach außen gerichtete Vakuumpumpöffnung versenkt angebracht ist.The invention eliminates these deficiencies and thus also the protective cover in that in the inwardly curved bottom of the outer bottle piston in place of the capillary cones an outwardly directed vacuum pump opening is sunk is.

Durch diese Einrichtung wird die Isolierflasche standfest, und die Vakuumpumpöffnung liegt geschützt und ist nicht hinderlich. Man kann daher diese Isolierflasche ohne Schutzhülle verwenden. Der Erfindungsgedanke läßt sich auch auf andere gleichartige Gefäßformen übertragen.Through this facility, the vacuum flask is stable, and the The vacuum pump opening is protected and not a hindrance. One can therefore do this Use vacuum flask without protective cover. The idea of the invention can also transferred to other similar vessel shapes.

Aus der Zeichnung ist eine Ausführungsform des Isoliergeräts nach der Erfindung ersichtlich.From the drawing is an embodiment of the insulating device according to of the invention can be seen.

Die leiden Flaschenkolben i und 2 sind oben am Rand .I d.;s Halses 3 miteinander verschmolzen, nachdem der innere Kolben 2 von oben in den äußeren Kolben i hineingesteckt und der Hals' 3° an den Hals 3 in die Lage 3b angedrückt wurde. Der äußere Flaschenkolben i hat einen nach innen gewölbten Boden 5, in dem eine nach außen gerichtete kapillare Öffnung z. B. in Form eines kleinen Zylinder- oder Röhrenansatzes 6 versenkt angebracht ist. Diese kleine Vakuum.pumpöffnung scann leicht durch ein Schmelzgerät 7 zugedrückt und verschmolzen werden. Es entsteht so eine kleine Schmelzstelle, die nicht hervorsteht und durch ihre im Boden versenkt.° Lage nicht gefährdet ist.The bottlenecks i and 2 are at the top of the rim. I d.; S neck 3 fused together after the inner piston 2 from above into the outer Piston i inserted and the neck pressed 3 ° against the neck 3 in position 3b became. The outer bottle piston i has an inwardly curved base 5 in which an outwardly directed capillary opening e.g. B. in the form of a small cylinder or tubular extension 6 is mounted sunk. This small vacuum pump opening is scanned easily pressed shut by a melter 7 and fused. It arises such a small melting point that does not protrude and sunk into the ground through her. ° Location is not endangered.
