<p>Two-part outlet closure for containers, esp. for liquids, consists of a cap the front wall of which is fitted with a through bore leading into a recess in which a rocker arm has a swivel bearing. The rocker arm is flexible and is equipped with a passage channel. That end of the arm facing the through bore has a largely rotation symmetrical surface which provides a seal for the arm while adjoining it in a vertical position relative to the axis of the through bore on the cap side. The sealing surface (23) has a sprung elastic fit on the rocker arm (20). The sealing surface consists of a wall section (23) which has - at least at one end -a single piece connection to the tip-up lever.</p> |
