Claim 0:
1. A fluid dispenser comprising a barrel defining a longitudinal axis terminating at a first fluid delivery end region; a dispenser body movable in a first phase along the barrel relative to the first fluid delivery end region between a pre-dispensing configuration and a dispensed configuration, and in a second phase along the barrel relative to the first fluid delivery end region between the dispensed configuration and a locked post-dispensing configuration, wherein the dispenser body is configured to rotate about the longitudinal axis during the first phase for aligned orientation with at least one locking structure configured to lock the dispenser body in the locked post-dispensing configuration during travel in the second phase, wherein the dispenser body includes a needle carrier with a second fluid delivery end region defined thereon, the dispenser body includes a fluid capsule carrier moveable relative to the needle carrier in the first phase to dispense fluid from a fluid capsule on the fluid capsule carrier, wherein the dispenser body includes a plunger structure movable relative to the fluid capsule carrier in at least part of the first phase to pressurize the fluid capsule; and at least one rotation interface defined across a plurality of cooperating elements respectively on the fluid capsule carrier and at least one of the plunger structure and the needle carrier, to enable axial rotation of the fluid capsule carrier relative to the barrel, wherein the at least one rotation interface includes a first rotation interface provided between the fluid capsule carrier and the plunger structure and/or wherein the at least one rotation interface includes a second rotation interface provided between the fluid capsule carrier and the needle carrier.
