Abstract
A stopper is provided which is intended to replace the lid fitted at the production stage, for the screw closure of bottles for liquids, with a device for drawing up metered amounts of the product. A stopper includes a capsule (9) with internal thread for screwing onto the threaded neck (1A) of the bottle. The capsule (9) forms coaxially and in one piece a cylinder (12) of a syringe metering device (10). The syringe metering device(10) has a control rod (16) which is graduated to allow measurement of the suction stroke of the plunger and hence to allow measurement of the amount of liquid drawn up.
