Abstract
The invention relates to a method of capping a hollow container, the container including a neck which defines an opening towards the interior of the container, the capping method including the following steps: placing a film over the entire edge of the opening in the container so as to cover the opening; deep drawing the film in the opening in the neck of the container with a die, such that the film forms a collar, a central region and a riser at the junction between the collar and the central region, the riser being in contact with the inner wall of the neck; and securing the deep drawn film to the neck, thus rendering the film integral with the body of the container.
