  • connection elements are an embodiment of the invention in the course of blow molding a drip pan made of plastic connected to the tub side walls.
  • connection elements it can are an injection molded part.
  • the connection element consists of the same or at least a similar material to the drip pan.
  • the connector should be a good one weldable material.
  • the connecting element is inserted into the Blow mold preheated.
  • connection element on the inside of the tank from the side wall of the tub is covered.
  • the connection element is located in other words on the outside of the drip pan.
  • connection element uninterrupted or open from the Tub side wall covered This can be done in a simple way ensure that the drip pan is also in the connection area between connection element and assigned Tub side wall is tight. But it is also in the frame the invention that the tub side wall or so connected connection element with suitable openings, Slitting and the like can be provided, the connection serve the connecting element.
  • the tightness of the drip pan is through the intimate material connection between the tub side wall and the connection element in the other areas guaranteed.
  • the invention further teaches a method for producing a liquid tank of the type described at the outset, two connecting elements being inserted on two opposite sides of a blow mold for the collecting trough, the collecting trough is then produced by blow molding and a material connection between a connecting element and the associated trough side wall is realized in each case and then the inner container and the connecting element are inserted into the collecting trough with the proviso that each end of the connecting element is connected to a connecting element.
