Container lid with tear-off ring - has attached to remainder of lid to form pull ring
Реферат: The tear-off is removed at first opening. The container (1) has grooves (3, 4) round its top edge. The lid (5) is of flexible plastic material and has a peripheral groove into which the rim of the container fits. A rim engages in the upper groove (4) and the tear-off ring is initially in the lower groove (3). The tear-off ring is removed upwards using a tab (13) and is attached to the remainder of the lid at a non-weakened point (12) so that the ring can be used to pull off the lid.
