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. Additionally or alternatively it is proposed to provide such a drinking bottle (10) with a temperature sensor (56), wherein the electronic evaluation unit (30) is adapted to activate and deactivate the distance sensor (50) as a function of a temperature measured by this temperature sensor (56).
