摘要： The invention relates to closure devices with opening indication element for bottles with a threaded neck. The closure device for bottle having a neck, comprising a pour sleeve (10) made with the ability to be installed on the neck, a closed sleeve (1) with means of fixation on the pour sleeve (10), a sealing means (11), an open sleeve (3) and an indicator ring (5), wherein the closed sleeve (1) and the open sleeve (3) form a cavity (4), and the indicator ring (5) is provided with an annular belt (6) placed in said cavity (4) before the first opening. The annular belt is made with the ability to be released from said cavity during the first opening and preventing the return of the indicator ring to its initial position when closing the bottle again. In another embodiment, the open sleeve can form a cavity with the closed sleeve (1), as well as an indicator ring (5) with annular belt (6) placed in the cavity (4) with the ability to be released during the first opening and preventing the indicator ring (5) from returning to its initial position when the bottle is closed again. Technical result of the invention is increased reliability and security of the closure cap indicating any opening by improving the visual indication of opening of the bottle and strengthening the protection against its bad-faith reuse.
