A lid-spout assembly for a package for a pourable product; wherein the lid-spout assembly comprises: • a collar comprising a pouring outlet and an outer surface; • a coupling ring arranged around the collar; • a lid connected to the coupling ring, wherein the lid is configured to be moveable between • an open position wherein the pouring outlet is opened; and • a closed position wherein the pouring outlet is closed; wherein the collar comprises: • a first ridge protruding from the outer surface of the collar; • a second ridge protruding by a second ridge distance from the outer surface of the collar and being axially displaced from the first ridge; • a groove defined between a lowersurface of the first ridge and an upper surface of the second ridge; wherein the coupling ring comprises: • an inner surface facing the outer surface of the collar; • a plurality of flap elements, wherein each flap element comprises a proximal portion, a middle portion, and a distal portion; wherein: ∘ the proximal portion is attached to the inner surface of the coupling ring, ∘ the middle portion extends between the proximal portion and the distal portion, wherein a longitudinal axis of the middle portion extends in a middle portion direction, ∘ the distal portion is configured to be arranged in the groove, wherein ▪ an upper abutment surface of the distal portion is configured to abut the lower surface of the first ridge, ▪ an end abutment surface of the distal portion is configured to abut an end surface of the groove, ▪ a longitudinal axis of the distal portion extends in a distal portion direction, wherein the distal portion direction extends at a non-straight angle from the middle portion direction, ▪ wherein the distal portion extends by an end distance from the middle portion into the distal portion direction, wherein the end distance is greater than the second ridge distance that the second ridge protrudes from the outer surface of the collar. • a collar comprising a pouring outlet and an outer surface;
