An apparatus and method of delivering a predetermined volume of a liquid product, defined as the liquid end product, formed by addition of a first and second liquid product, into a thermoplastic container formed from a heated preform positioned in a mold and having an opening opposite an injection head. Prior to injecting the second liquid product into the preform causing expansion of the container, the preform is at least partially, filled with the first liquid product.

In a method for operating an apparatus for transforming plastic preforms into plastic containers, the apparatus acts upon a flowable medium to plastic preforms in order to expand these plastic preforms to form the plastic containers, and the apparatus carries out this transforming operation while taking account of a plurality of process parameters. The plurality of process parameters is determined on the basis of a machine model, wherein a predefined number of input parameters are transferred to this machine model and at least one processor unit determines the process parameters and/or values characteristic of these process parameters on the basis of these input parameters.
