A device for delivering a dose of medicament includes a generally elongated housing, a container containing medicament to be injected through a needle, a force device acting on the container and capable of, upon activation, moving the container and the needle for penetration and subsequently expelling medicament through the needle, and an activating device arranged to activate the force means. The data stream is divided into a sequence of blocks, and a detection interval is defined including a predetermined number of blocks in the sequence. The method comprises a dual film continuous dual laminating process for producing a metallized laminate. The fitting is filled with fluid from the container by turning the sleeve in a direction away from the closed position on the nipple to an open position to thereby establish fluid communication between the container and fitting.
