Closing arrangement for a cap of a tube in a carrier, wherein the arrangement comprises at least three moveable engagement members, wherein the three moveable engagement members are guided coaxially to one another to close the cap of the tube,
- wherein the three engagement members comprise a fixture for the carrier, a guide finger, and a pushing element, wherein an inclined surface is adapted for engagement with the cap and for a transfer of movement of the cap relative to the tube, wherein the inclined surface is further adapted as a guidance for the guide finger;
- and
- wherein the inclined surface and the guide finger are adapted for a relative translatory movement towards each other, and the guidance of the inclined surface allows for a sliding movement of the guide finger relative to the inclined surface.
Method of closing tubes, each tube being connected with a cap, the tubes being arranged on a carrier, wherein an inclined surface, a guide finger, and a pushing element are provided, wherein the method comprises:
- moving a cap by the inclined surface, impinging the guide finger on the inclined surface, guiding the guide finger by the inclined surface, moving the cap by impact of the guide finger, pushing the cap by the pushing element to close the cap.
