Claims (5)

1. Wärmekissen, gefüllt mit
  • 1. einer unterkühlten, wässrigen Natriumacetatlösung (20),
  • 2. einem elastisch verformbaren Gehäuse (34) innerhalb dieser wässrigen Lösung (20),
  • 3. einem metallischen Körper (24) innerhalb des Gehäuses (34), der in dem Gehäuse (34) so gelagert ist, dass dieser metallische Körper (24) bei elastischer Verformung des Gehäuses (34) eine solche elastische Verformung erfährt, dass dadurch eine Kristallisation der Lösung (20) in einem exothermen Prozess auslösbar ist, dadurch gekennzeichnet, dass
  • 4. der metallische Körper aus einer einzelnen Schraubenwendel (24) besteht,
  • 5. das Gehäuse ein Kunststoffüberzug (34, 34.2) ist,
  • 6. der Kunststoffüberzug (34, 34.2) fest auf der Wendel (24) vorhanden ist,

3. Wärmekissen nach Anspruch 2, dadurch gekennzeichnet, dass
  • 1. der Überzug (34, 34.2) in Richtung der Längsachse (40) der Wendel (24) das freie Ende der Wendel (24) überragt.
3. Heat pad according to claim 2, characterized in that
  • 1. the coating (34, 34.2) of the helix (24) extends in the direction of the longitudinal axis (40), the free end of the coil (24).
4. Wärmekissen nach Anspruch 2, dadurch gekennzeichnet, dass
  • 1. der Überzug (34, 34.2) das freie Ende der Wendel (24) umgreift.
4. Heat pad according to claim 2, characterized in that
  • 1. the coating ( 34 , 34.2 ) engages around the free end of the helix ( 24 ).
5. Wärmekissen nach einem der vorstehenden Ansprüche, dadurch gekennzeichnet, dass
  • 1. der Kunststoffüberzug (34) ein Spritzgussteil ist.
5. Heat cushion according to one of the preceding claims, characterized in that
  • 1. the plastic coating ( 34 ) is an injection molded part.
