Sealing cap for sealing a filler neck of a liquid container comprises a restoring device formed by a control element rotationally fixed to a cap body or a sealing body and rotatably fixed to the other component

摘要

Sealing cap comprises a sealing body (2) anchored in a form-locking manner in a filler neck (1) on rotation about an axis of rotation (D), an upper cap body (3) rotatably mounted on the sealing body about a release angle ( alpha ) defined by a first stop in a closed position and a second stop in an open position, and a restoring device which rotates the upper cap body automatically from the open position back into the closed position. The restoring device is formed by a control element (4) rotationally fixed either to the cap body or to the sealing body and rotatably fixed about the axis of rotation via a guide thread to the other component (cap body or sealing body). The first stop and the second stop restrict the longitudinal movement of the control element. Preferred Features: The rotationally fixed connection of the control element is designed so that the control element is positioned on the cap body or the sealing body in an axially displaceable manner parallel to the axis of rotation.
