ABSTRACT A method and an apparatus for producing a container (10) filled with goods (60) and possessing superior mechanical stability are dis- closed. A preform (10a) which is filled with the filling goods, consists of crystallizable plastic material and comprises a bottom portion (11a) and an opening portion (13), is reformed into the container by means of a mechanical forming tool (20). On the reforming of the bottom portion, the mechanical forming tool displaces the bottom portion towards the opening portion of the preform under simultaneous temperature conditioning of the material of the bottom portion, The mechanical forming tool abuts against the bottom portion for such a length of time that the bottom portion obtains a total crystallinity of at least 15%. An apparatus according Lo the invention includes a holder (50) in which the preform (10a) is received and in which the preform is retained on reforming of its bottom portion, and a mechanical forming tool (20) with an abutment surface (22) which, by means (26), is given an elevated temperature. The apparatus is included in equipment for filling of the preform with filling goods and the forming tool is disposed for the above-mentioned displacement of the bottom portion, once the preform has been supplied with filling goods and for retention of the abutment surface during a predetermined period of time at an end position of the above-mentioned displacement.
