1. An injector system for needleless, high pressure delivery of a medicament, the system comprising:

  • an injector comprising;

    an injector body, andan injector piston which is movable within the injector body such that when the injector piston is moved away from an initial position an injector chamber is defined by the injector body and the injector piston, the injector body having a distal end defining an outlet of the injector chamber;

    a medicament container comprising;

    a reservoir for accommodation of a medicament, the reservoir defining an outlet in a distal end, anda reservoir piston movable within the reservoir;

    a fluid connection adapted to be fluidly connected to the outlet of the reservoir;

    wherein the injector body is movable in relation to the fluid connection between;

    a first position, wherein the outlet of the fluid connection is not fluidly connected to the outlet of the injector body, anda second position, wherein the outlet of the fluid connection is fluidly connected to the outlet of the injector body such that when the fluid connection additionally is fluidly connected to the outlet of the reservoir, movement of the reservoir piston towards the distal end causes the medicament to be pressurised whereby the injector piston is moved away from the initial position and the injector chamber is filled; and

    wherein the fluid connection and/or the injector comprises holding means for holding the injector body in each of the first and second position relative to the fluid connection.
