The invention relates to an opening and pouring system for disposable containers that are manufactured with a laminate made of plastic, carton and aluminum and used for packing beverages. Said containers have two flaps (2-2'), each of which comprises two right triangles that are reciprocally folded by identical common sides which, once superimposed, form a narrow cavity (4) that gradually extends from the vertex towards the hypotenuse until it communicates with the interior of the container (1). One of the flaps (2-2') has an orifice (3) in the triangle (5), contacting the small vertical face (6), which is sealed with a strip prior to filling and which is then torn off before pouring.
