| 摘要 |
The specification describes a plastic closure adapted to be screwed onto the neck (1) of a plastic container, with a screw-on ring (5) and with an insert portion (11) comprising a flexible bellows (14) and a pour spout (15), with a frame cap (21) adapted to be screwed on to an external thread (19) on the spout. In order to maintain good pouring properties, e.g. by means of the flexible bellows, and to make automatic production simpler and cheaper, the invention proposes that the frame cap (21) is integral with the screw-on ring (5), and the top wall (23) of the cap (21) is moulded on so that it projects a distance (d) from the top wall (8) of the ring (5).
