A method for joining at least two plastic parts () along a predeterminable common joining point using infrared radiation (IR), is characterized in that each of the plastic parts () to be joined is heated using infrared radiation at least along the joint by radiation sources without touching the respective plastic parts (). One radiation source is operated independently and spatially separated from the other radiation source. The radiation sources emit their respective infrared radiation to the respective plastic parts () without contact and following the contour of the joint. The degree of heating by the respective infrared radiation is selected such that the joint is formed when the plastic parts () are brought together.

Method and apparatus for joining at least two plastic parts

A sealing arrangement is for a container () and/or container part, such as a closure cap placed onto the container (). The interior of the container () is used to accommodate a medium, particularly a fluid bottled in a sterile manner, which can be removed from the container () by a removal device such as a syringe needle. The removal device penetrates sealing material () connected to the container. The sealing material () is fixedly connected to the outside () of the container () and/or container parts facing the environment by a fused and/or adhesively bonded connection.
