摘要：A spout (1) for a flexible pouch (100) for liquid food, such as fruit juices, yoghurt, fruit or vegetable purees and the like, comprises a tubular barrier (30) embedded in the tube (18), made of a material impermeable to atmospheric oxygen. The spout is made by moulding equipment which comprises a counter-mould (300) with fixed insert (302) and a movable skirt (304), slidably fitted on the fixed insert (302). The spout may be made by means of a production method in which, during the injection of a first oxygen permeable plastic material, the skirt (304) is moved, coming out of the barrier (30), which remains in a fixed initial position.
