Container comprising code information elements

This invention relates to a container ( 10 ) for a medication delivery ( 110 ) device comprising an optical reader ( 111 ), where said container comprises a code information element ( 20 ) carrying a set of information readable by said optical reader where the container comprises at least one more code information element ( 20 ) carrying the set of information readable by said optical reader. The invention further relates to a method of applying code information elements onto the container and to a method of reading a code information element. The code information elements can be aligned with at least one protrusion on the container, or are aligned with at least one cavity on the container. Alternatively or additionally, the code information elements are juxtaposed to one another. Hereby, an optical code reader, embedded in the medication delivery device, will be able securely to read the information carried by means of image processing software compiling and combining more code information elements. With more code information elements available, it is possible to re-create a perfect image from several code information elements applied on the container. Thus, the undesirable effects, arising from humidity, dirt, dirty or sweaty fingers damaging the code information elements are minimised.
