It has extending from the grip edge (3) a cylindrical portion (5) open towards the inside of the bottle. At the open end there are a number of protrusions (6) or recesses, spaced round the periphery, engaging with complementary recesses or protrusions (7) on a cylindrical extension piece (8) from the bellows (2), so that stopper and bellows are positively coupled together.
