Patent ID: 10640351

Abstract:
A method and apparatus for applying a cap to a container may include arranging a first cap in relation to the neck portion of a first container, such that a threaded portion of the first cap faces a complementary threaded neck portion of the first container. Further, a symmetry axis of the first cap and a symmetry axis of the neck portion of the first container may be aligned. The first cap may be rotated around its symmetry axis to a pre-recorded initial angular position. The first cap may be applied to the neck portion by moving the cap towards the threaded neck portion or vice versa along their symmetry axes and by rotating the first cap in a direction of engagement with the threaded neck part. A path length of the first cap may be recorded in relation to its initial angular position after which it has completely engaged the complementary threaded neck portion and reached a bottom part of the neck portion. If the recorded path length for the first cap deviates from a predefined value, the initial angular position of a second cap may be adjusted to a new initial angular position.
