Delivery device and method for its operation
First Claim
1. A method for operating 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 method comprisingtransmitting radiation towards a 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.

Abstract
Provided is a method for operating a preparation delivery device wherein the device comprises 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 method comprises 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.

44. A method for operating 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 method comprising
transmitting radiation towards a 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, and comparing the characteristics of the received radiation with a predetermined characteristic representative of a predetermined functional property of the container or its content, to establish if the predetermined functional property of the container or its content is present and thereby verify a status of the container acceptable for use.
