Abstract: Drinking bottles (10) are known from the prior art comprising a bottle body (12) for holding liquid and a closure unit (20) with a movable or removable lid (40), said drinking bottles (10) having electronic evaluation unit (30) which are adapted to evaluate at least one sensor signal, wherein the closure unit (20) of such a drinking bottle comprises an optical distance sensor (50) directed into the bottle body (12) to detect the amount of liquid remaining in the bottle body (12) It is proposed to enhance such drinking bottles with a closure unit (20) having an insulation wall (60) which, in the closed state, isolates an electronic space (42) from an interior of the bottle body (12), wherein the distance sensor (50) is arranged in this electronic space (42) and wherein the insulation wall (60) is penetrated by at least one aperture (62, 64) in which a transparent light conducting element (72, 74) is arranged.

Abstract: Smart bottles (10) with a bottle body (12) and a closure unit (20) are known from the prior art. A closure unit (20) is provided having a base (30) and a hinged lid (80) pivotally attached to the base (30), said hinged lid (80) being secured in a closed position by a retaining portion (42) of the base (30). A first button (44) is provided on the base (30), by means of which the retaining portion (42) can be pressed into a release position releasing the hinged lid (80). Furthermore, the closure unit (20) has a locking System (50) with a second button (54). Said second button (54) is coupled to a push-in lock (56) which can be switched between a locked state and an unlocked state by means of the second button (54), wherein the first button (44) being locked in the locked state.

Abstract: Method for monitoring the use of a drinking bottle and a system for carrying out the method. A drinking bottle is designed to detect, on the basis of sensor data of at least one sensor, whether the dispensing of liquid from the drinking bottle is caused by drinking and to distinguish this from dispensing processes which do not represent drinking processes. An evaluation system collects sensor data of the at least one sensor. The evaluation system evaluates this sensor data, and if the dispensing was caused by a drinking process, stores the number of drinking processes and/or the volume of the liquid dispensing caused by drinking.
