摘要

A closure or closure element manufactured by injection moulding and provided with an easy opening device having a pull-ring and a tearing strip emerging therefrom. The tearing strip forms and defines a region which is concave. A recess is arranged cross-wise in a major part of an inlet to the concave region. The recess can be formed by the injected molten material having been diverted and delayed when entering the concave region. The delay enables the concave region and the portion of the tearing strip defining it to be formed substantially simultaneously. The orientation of the material at the junction of the tearing strip and the concave region is also diverted.
