Abstract
A closing arrangement for a packing container is disclosed including a tubular member that may be firmly anchored within a pouring opening of the container. A cap member closes the tubular member and is provided with a pull-ring. The cap member is joined to the tubular member by a first connecting member which may be broken to open the container. The cap member is also joined to the tubular member by a second connecting member which forms a hinge located diametrically opposite to the pull ring. The second connecting member retains the cap member on the tubular member after the container is opened. The pull ring includes a locking element which cooperates with the tubular member to provide a catch. Upon movement of the pull-ring to open the container, the catch is caused to disengage from the tubular member. In this way, the first connecting element is broken but the catch permits a reclosure of the container. The closing arrangement is preferably made of a plastic material especially polyolefin.
