Closing device with integrated rotary closure for feeding bottle and bottle

A device for sealing a feeding bottle or bottle, characterized in that it comprises:

• a teat
• a retaining ring
• an internal screw thread intended to collaborate with the screw thread of the feeding bottle or bottle, characterized in that it comprises a repositionable rotary safety closure inserted between the retaining ring and the screw thread of the feeding bottle or bottle, this closure being able to be moved between a position in which it completely closes the feeding bottle or bottle and a position that allows a liquid contained in the feeding bottle or bottle to flow, the repositionable rotary closure comprising two superposed ferrules, with their top surfaces in the form of flat disks, each having an opening and configured as follows:
• an external ferrule bearing a screw thread intended to accept the retaining ring and a first disk having an off-centered opening partially closing off the feeding bottle or the bottle, the surface area occupied by the opening being more than ¼,
• an internal ferrule bearing an internal screw thread and a second disk having an off-centered opening partially closing off the feeding bottle or bottle and in contact with the first disk, it being possible for the external ferrule to be orientated in such a way that the openings and of the first and second disks respectively face one another to allow a liquid contained in the feeding bottle or bottle to flow and in such a way that the openings and of the first and second disks respectively are offset, completely closing off the feeding bottle.
