Method for producing a pouch (10) for holding a beverage. The method comprises forming a valve device (11) in a sheet (1) of pouch material by: folding the sheet (1) on three parallel folding lines (2, 3, 4), to obtain a double layered part (B, C) extending substantially perpendicular to the rest of the sheet (i); affixing the double layered part (B, C) together over a first fixation pattern (SI); cutting a first cutting pattern (CI) along a part of the fixation pattern (SI) and along a central part of a middle one (3) of the three parallel folding lines (2, 3, 4); and folding the sheet (1) back over the double layered part (B, C). The pouch (10) manufactured accordingly can be used for large scale production, and for distribution of various beverages. The pouch is easy to fill, and provides a well sealed pouch. |
