Pouring package as well as a method and system for manufacturing the same

Abstract

The invention relates to a method for manufacturing a pouring package, and the pouring package. The pouring package comprises a container ( 1 ) formed from a packaging material with an inner space bounded by walls ( 12,13,14,15 ) for receiving a fluid therein. The walls comprise a base ( 11 ), two partially triangular side walls ( 12 A, 12 B) rising therefrom and a front and rear wall ( 13,14 ) which are connected to the base, extend between the side walls and are mutually connected between the top corners ( 17 ) of said triangular side walls ( 12 A, 12 B) in a closing strip ( 15 C). The front and/or rear wall is provided with a weakening line ( 18 A, 18 B), such that the closing strip ( 15 C) can be pressed in toward the base in order to deform the front and/or rear wall along the weakening line for of forming an upper wall ( 15 A, 15 B) extending between the top corners.
