Description

Wärmflaschenverschluß mit Sicherheitsventil Die Erfindung bezieht sich auf Wännfiaschenverschlüsse, die als Sicherheitsventil wirken. Gemäß der Erfindung ist die Verschraubung des Verschlusses mit' einer Ringkammer versehen, die durch Lochungen mit dem Inneren des Ventilverschlusses in Verbindung steht. Dadurch wird austretender Dampf von der Tragvorrichtung der Wärmflasche abgeleitet und ein Verbrennen beim Tragen der Flasche vermieden.Hot water bottle cap with safety valve The invention relates on bottle closures that act as a safety valve. According to the invention the screw connection of the closure is provided with an annular chamber, which through Perforations with the interior of the valve closure is in communication. This will escaping steam is diverted from the carrying device of the hot water bottle and burns avoided when carrying the bottle.

Wie der Längsschnitt in der Zeichnung erkennen läßt, ist auf den an sich bekannten Verschraubungsteil a mit Ventilteller c eine Verschlußschraubee aufgesetzt, die eine unten offene Ringkammer g, h hat, welche durch Löcher f mit dem Ventilraum in Verbindung steht. Es wird demnäch bei Überdruck in der Wärmflasche unter Anheben des- durch die Feder d belasteten Ventiltellers c ausströmender Dampf durch die Locher f zur Kam> mer g, h -gelangen und hier, gleichmäßig verteilt, so abgelenkt werden, daß die Trageinrichtung (Tragring) nicht getroffen wird. Ein Verbrennen ist. somit vermieden. Der Erfindungsgegenstand kann an bereits vorhandenen Wärmefiaschemn ohne weiteres gegen die alte Verschlußschraube umgewechselt. werden.As the longitudinal section in the drawing shows, is on known screw connection part a with valve disk c a screw plug is attached, which has an annular chamber g, h which is open at the bottom and which connects to the valve chamber through holes f communicates. It is then raised when there is overpressure in the hot water bottle des- by the spring d loaded valve disk c escaping steam through the Hole punch f to chamber g, h-get and here, evenly distributed, so deflected be that the support device (support ring) is not hit. A burn is. thus avoided. The subject matter of the invention can be attached to existing heat bottles easily exchanged for the old screw plug. will.
