The channel is adjacent to at least one of the edges of the packaging and extends from one end to the other of said packaging. At least one of the channel ends is sealed and in internal communication with the main compartment while the other may be opened for pouring. According to the method, a strip-like partition is inserted between the two side walls of the packaging and at least one longitudinal mid-portion (13) of the strip constitutes said partition and has evenly spaced communicating means (8) arranged above the bottom seal (10) of the packaging, and each side wall of the packaging is sealed to one edge of the partition.
