    Abstract: A method and device for the production of a closure cap having a first part (16, 17) and a second part (18), joined together by at least one thinner section (19). The device contains a female mould part (11) and a male mould part (12), which are moveable relative to one another, in order to enclose a mould cavity. After the closing of the mould cavity, an additional mould part (14) is moveable relative to the mould cavity. In order to reduce the volume thereof, until the plastics material fills the mould cavity completely. Consequently the invention ensures that when compression moulding in the mould cavity, the closure cap and in particular also the thinner section (19) are formed completely in the mould provided.
