Abstract
An end closure for a packaging container where the closure is of the basic type having a so called one step opening arrangement, i.e. where an outer layer and an inner layer are removed in unison or simultaneously by shaping the tearing denotations in a proper pattern. In order to provide an opening procedure giving less splash the outer layer is divided into a central part having a grip for individually removing the central part from the inner layer laying under the outer layer without being connected thereto. A circumferentially extending region all around the closure, is defined by said circumferential tearing denotation and the central part and is removable together with the inner layer inside the tearing denotation.
