Set consisting of a pump dispenser for dispensing pharmaceutical or cosmetic liquids and an evaluation unit with the following features: a. the pump dispenser has a liquid store, to the upper end of which a dispensing head is attached, and b. the dispensing head has a base which is fastened to the liquid store, and a pushbutton which can be pressed down with respect to the base for the purpose of dispensing, and c. the dispensing head has a pumping device which can be actuated by way of pressing down of the pushbutton, and which, in the case of actuation, conveys liquid from an inlet channel which is connected to the liquid store to a dispensing opening which is provided on the dispensing head, and d. the evaluation unit is configured for the detection of the actuation of the pumping device, the evaluation unit being configured as an external evaluation unit which has a receiving container which is open at least on one side and into which at least the liquid store is inserted in releasably, with the result that at least the dispensing opening protrudes out of the receiving container at a first upper end, a detection sensor being arranged at an opposite second end of the receiving container or of a closure which is attached thereto, which detection sensor is loaded with force by way of the liquid store when the pushbutton is pressed down, with the result that the actuation of the detection sensor can be detected, characterized by one of the following features: e. the receiving container has a length which is sufficiently great, in order that the liquid store can be received completely or virtually completely therein, the receiving container being of permanently closed configuration at the second end and, at its first end, having an opening which is sufficiently large, in order that at least the liquid store can be pushed in, or f. the receiving container is of open configuration on both sides, an opening at the first end having at least locally a smaller clear cross section than a maximum cross section of the pump dispenser, with the result that the pump dispenser can be pushed from the inside through the opening only partially, but at least with the dispensing opening. a. the pump dispenser has a liquid store, to the upper end of which a dispensing head is attached, and b. the dispensing head has a base which is fastened to the liquid store, and a pushbutton which can be pressed down with respect to the base for the purpose of dispensing, and c. the dispensing head has a pumping device which can be actuated by way of pressing down of the pushbutton, and which, in the case of actuation, conveys liquid from an inlet channel which is connected to the liquid store to a dispensing opening which is provided on the dispensing head, and d. the evaluation unit is configured for the detection of the actuation of the pumping device, the evaluation unit being configured as an external evaluation unit which has a receiving container which is open at least on one side and into which at least the liquid store is inserted in releasably, with the result that at least the dispensing opening protrudes out of the receiving container at a first upper end, a detection sensor being arranged at an opposite second end of the receiving container or of a closure which is attached thereto, which detection sensor is loaded with force by way of the liquid store when the pushbutton is pressed down, with the result that the actuation of the detection sensor can be detected, e. the receiving container has a length which is sufficiently great, in order that the liquid store can be received completely or virtually completely therein, the receiving container being of permanently closed configuration at the second end and, at its first end, having an opening which is sufficiently large, in order that at least the liquid store can be pushed in, or f. the receiving container is of open configuration on both sides, an opening at the first end having at least locally a smaller clear cross section than a maximum cross section of the pump dispenser, with the result that the pump dispenser can be pushed from the inside through the opening only partially, but at least with the dispensing opening.
