摘要

A unit closure for hermetically sealing a liquid bottle is a hollow teat with a cover. The teat has an outlet and a radially extending base flange with a fixing section. The cap presses the fixing section into place on the rim of the bottle. When the cap is removed the teat comes into contact with the atmosphere and the bottle contents. The fixing section of the flange is a ring or flange directed inwards which is clamped between the bottle rim and a hollow stopper (5) which is pressed into the bottle top. The stopper has openings which are closed when the cap is on and opened when it is removed.
