Drip stopper and packaging therefor

A drip stopper being insertable into a neck of an opened bottle for preventing the undesired falling of drops during pouring from the bottle into a drinking vessel, the drip stopper comprising a radially flexible substantially cylindrical wall having an axial length, the wall defining an insertion part which in an inserted state extends into the bottle neck, a pouring-out part which in an inserted state protrudes above an upper edge of the bottle neck, a plurality of radially outwardly oriented position elements between the insertion part and the pouring-out part and a folding zone constituted by an axially parallel nook-shaped recess which extends over the entire length of the wall wherein the recess comprises inwardly directed side walls, the side walls together with the cylindrical wall forming two opposing axially extending edges which are approximated by narrowing the cylindrical wall and wherein the folding zone by this narrowing transfers tension force between adjacent areas of the recess and the cylindrical wall.
