Abstract

The invention relates to a single-piece closure (V) produced according to a plastic injection method. Said closure comprises a closing cover (6) and a wall (8) extending from the edge (7) of the cover (6) downwards. A tear-off lug (13) is formed in the wall (8) of the closure by two vertical thin places (14) which are formed at a peripheral distance in the wall (8) of the closure and which lead to a hinge area (15) formed on the upper side therebetween. In order to form the tear-off lug which can continue to fulfil the function of a grip element, whereby the first utilization thereof can be indicated in a more effective manner, the geometry of the bead (17) is identical, having the same depth over the entire internal wall area, including the inner surface of the tear-off lug (13), in a radially inner direction; the beading (17) is associated with the hinge area (15), and the thin places (14) are formed exclusively between the peripheral area of the wall (8) of the closure which remains once the tear-off lug has been opened and the hinge area (15). Alternately, when seen from the tear-off lug (13), a deflecting wall (24) which protrudes in a radially outward manner, extending in a vertical direction is formed beyond a vertical thin point (14), said wall extending into a covering (U), as far as the tear-off lug (13) .
