Abstract
A preparation delivery device comprising a) a container for the preparation having or being prepared for the arrangement of an opening, b) a mechanism operable to deliver at least part of the preparation in the container through the opening, c) attachment means for connection of the container to the mechanism and d) a sensor system arranged to detect at least one predetermined property of the container or its content. The device comprises a radiation transmitter arranged to irradiate the container position or a part thereof, a radiation receiver arranged to receive at least an area part of the radiation from the transmitter after the radiation having been affected by the container position and the receiver being designed to give an output response representative for the total radiation received from said area part. A method for operating the device comprises the step of transmitting radiation towards the container position or a part thereof to allow the radiation to be affected by the container position, receiving at least a part of the affected radiation from at least an area part of the container position in a non-imaging way and comparing the characteristics of the received radiation with a predetermined characteristic representative for the predetermined property to establish whether or not the predetermined property of the container is present.
