<p>The invention relates to a spout closure (1) for liquid packagings (2), which comprises a pouring neck (9) with a radially projecting lower rim (12) and a screw lid (11). Said screw lid (11) has a larger diameter than the pouring neck (9) and an elastically deformable ring element (10) is disposed between the pouring neck (9) and the screw lid (11). The ring area (13) of said ring element extends at an oblique angle to the ring plane, the inner ring rim (14) running into a projection (15) that projects downward and that can be put over the pouring neck (9). The outer ring rim (16) runs into a projection (25) that projects upward and that is provided with an external thread (26) onto which the closure lid (11) is screwed. The ring element (10), when elastically deformed, may shift into two stable states, namely firstly into the state in which the ring area (13) slopes from the inner (14) to the outer ring rim (16). In this state, the spout closure (1) is compressed and is less than 5 mm high. In the other state in which the ring area (13) ascends, the spout closure (1) is approximately three times as high and allows a reliable pouring of the liquid across the flared flange (6) of the liquid packing (2) that is spaced approximately 11 mm from the pouring neck (9) and is 5 mm high.</p> |
