Abstract
A closing arrangement made of plastic material for packing containers includes a tubular part which is anchored in an opening provided in the pour opening of the container and a cap member attached to the tubular part at one side and which includes a pull ring extending from the other side. The cap member is also attached to the tubular part by means of a frangible region which is broken as the pull ring is lifted, and the cap is automatically retained in the open position to facilitate pouring of the contents from the container.
