ABSTRACT:
The present invention relates to a system for ensuring that the correct container (10) containing a replenishment fluid is connected to a vessel (26) for that fluid. The container carries one component (18) of a pair of axially engageable members (20). The other (28) is carried by the vessel (26, 27), notably around the necks extending therefrom, so that the members (20, 30) have to engage and nest so as to allow the necks of the container and the vessel to engage fully and thus mount the container on the vessel, one of the members (18, 28) being a moveable fit upon the container (10) or vessel (26), preferably by virtue of being a snap fit thereon, so that the member can be rotated to align its projections (20) with the recesses (30) on the other member. The invention is of especial application in ink jet printers to identify solvent and ink refill bottles and ensure that they are connected to the correct reservoir and by the use of the snap fit members allows a conventional refill bottle and reservoir to be used to achieve this.
