Abstract

A filler pipe for a packing machine for consecutively filling a traveling and continuous series of connected packing container blanks, with a liquid product such as yogurt, and a separate jam product, without mixing the two types of product. This filler pipe is used in conjunction with blanks formed of two joined webs and provides sealing of the filled packing containers. The invention utilizes a nozzle with multiple filling paths each of which passes product to at least one of the packing container blanks. The nozzle receives the liquid product from a flat shaped larger delivery pipe, and the jam product from a smaller delivery pipe parallel to the larger pipe. The smaller pipe, which may be located inside or on the outer wall of the large pipe, is placed at a predetermined distance above the junction of the larger delivery pipe and the nozzle. In this way each container is first filled with its share of jam product and then with the liquid (yogurt) product with no mixing of the two products. This invention represents an advance over existing packing methods which can only supply mixed products.
