Abstract
A readily openable and reclosable opening arrangement for use on a packing container comprises a pouring pipe attached to the outside of the packing container, wherein a slide is maneuverable within the pouring pipe by means of a projecting gripping element. When the slide is pushed to the open position the packing container wall is penetrated by ploughlike elements joined to the slide, so that the contents may be emptied out via the pouring pipe. The opening arrangement also may be used on packing containers which consist of several part containers whose contents may be emptied out through a joint pouring pipe.
