Container closure with a retractable turnspout

Claim 1

Container closure of plastics material for mounting on a container having a container mouth and a longitudinal axis, comprising; a) a closure plug (5) rotationally fixedly inserted in the container mouth and having a plug base, b) an upwardly extending bush (6) which is eccentrically arranged on the plug base and having an internal passage passing through through the plug base, d) a turret (9b) which sealingly engages over the bush and is rotatable around an axis of rotation and which together with a tube (9a) projecting from said turret transverse to said axis of rotation forms a turnspout, d) a continuous liquid passage in the turret and tube, e) a sealing means between the bush (6) and turret (9b), f) a cap (2) which lockingly engages over the closure plug and the container mouth along said longitudinal axis, is rotatable with respect to the closure plug and has a lateral opening (3) through which the tube (9a) passages in an operational position and one edge (35) of which cap serves to move the tube out of the operational position, said cap having a cap base, and a cap axis g) a shield (8) upstanding from the plug base (5a) for closing the lateral opening when the turnspout (9) is pivoted toward a closed position, h) a wall (26) which is on the cap base (2a), projects towards the plug base (5a) and extends concentrically to cap axis and having a first engaging edge (39) which peripherally limits said wall with said first engaging edge pivoting the tube (9a) out into its operational position, wherein: i) a longitudinal slot (7) is provided in the bush (6) which longitudinal slot together with an inward end of the liquid passage (9c) forms a tap, j) the shield (8) is partially cylindrical, has on its inner wall a projection (8a) for abutment by the free end of the tube and serves to limit the inward pivotal movement of the tube and the shield seals the free end of the tube (9a) when it has been pivoted to said closed position, k) the wall (26) projecting from the cap has towards the plug base has the shape, with the exception of an interruption, of a closed cylindrical wall whose outer diameter is somewhat smaller than the inner diameter of the shield (8), l) a first engaging side (39) is provided on the wall (26), and m) a second engaging (40) is provided on the wall (26) for pivoting the tube in towards the end of the inward pivotal movement until it is behind the shield in a predefined storage position.
