Abstract

The consumer, and in particular the beverage consumer, frequently demands different packaging units which consist of different beverages or different assortments of beverages. That means that packaging units must be assembled which contain, for example, two bottles of a carbonated fruit-flavor beverage and four bottles of a beverage containing cola. The labelling and other packaging of the container must correspond to the product In the individual container. The packaging units are generally assembled either manually or semi-automatically. The invention relates to a method which simplifies the preparation of packaging units which contain different filling products. The invention is characterized by the fact that to fill the containers according to a Specified or selected filling formation with different filling products, i.e. optionally with at least a first or a second filling product, the filling machine is controlled by a control device so that, as a function of the filling formation, the filling positions dispense different products into containers which are unique and appropriate to each product.
