Patent ID: 7117579

Claim:
Method of producing a combination packaging container comprising a beaker-shaped plastic inner part having a base and a casing-type outer part surrounding the plastic inner part and retained on the external face of the plastic inner part in an interlocking arrangement, by which method the two parts are pushed one inside the other in the interlocking arrangement, the outer part is retained in a holder, the plastic inner part is introduced into the outer part retained in the holder and then pushed down into the outer part so as to interlock, a first catch means being provided in the region of an open end face of the plastic inner part and a second catch means being provided in the region of the base to interlock the plastic inner part and the outer part, and before and during the process of pushing the plastic inner part into the outer part, the second catch means is reduced by means of a predefinable deformation of the base to a degree so that it corresponds more or less to an internal diameter of the outer part in the region of a smaller dimension and can therefore be pushed completely into the outer part while meeting a significantly reduced amount of resistance.
