Abstract: A container (1) with two receiving spaces (3, 5) for liquids that are to be mixed only just prior to use has a bottle-shaped lower part (2) with first receiving space (3) and an upper part (4) which can be mounted on lower part (2) and has a second receiving space (5). Second receiving space (5) is connected to receiving space (5) of lower part (2) by an opening, which is initially closed by a diaphragm (20) or a closure plug (35) and is opened only just before the mixed liquids are to be used. To do this, diaphragm (20) is slit by a cutting edge (36) corresponding to closure top (10). If the opening is closed by a stopper-shaped closure (35), closure top (10) has a plunger (40) for pushing closure plug (3) out. Both cutting edge (36) and plunger (40) are connected to the closure top so that they can be activated by a screwing motion of closure top (10).

Abstract: In a method for control of a sanitary mixer for cold and hot water, merely the actual temperature is continuously measured in the mixed water and compared to a preset temperature. At least two separate, time-varying regulating values, used for electromechanical adjustment both of the cold as well as of the hot water supply, are electronically derived from the difference between the set and actual temperature. A preset flow rate of the mixed water that is to be kept constant during temperature control is taken into account in the determination of the regulating values. Furthermore, partial flow rates for the cold water supply and hot water supply that are proportional to the regulating values can be determined from the time-varying regulating values. These are then used to continuously determine the instantaneous cumulative filling volume of the mixed water. As soon as a cumulative filling volume value equal to a preset cumulative filling volume is reached, the cold and hot water supplies can be shut off.
