1. A medicament delivery system, comprising:

  • a container for storing a medicament prior to use, the container having one or more openings therein, the container comprising;

    a first housing for containing a medicament;

    a stopper associated with the first housing;

    a second housing, wherein the first housing is held within the second housing, and the first housing is movable relative to the second housing;

    an injection member associated with a lower portion of the first housing;

    a spring disposed between the first housing and the second housing; and

    an actuation mechanism;

    wherein the actuation mechanism interacts with the container to move the first housing relative to the second housing in a first direction, such that the spring is in a biased state, the injection member is ejected from the second housing traversing a first contaminant barrier, and move the stopper relative to the first housing in a first direction to deliver the medicament through the injection member, such that when the first housing moves relative to the second housing in a second direction, the spring is in an unbiased state and the injection member is retracted into the second housing to prevent an unintentional contact with the injection member.
