Abstract

An apparatus includes a medicament container, a first elastomeric member, a second elastomeric member and a stopper. The first and second elastomeric members are disposed within the medicament container. The first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively define a medicament volume. The stopper is coupled to a distal end portion of the medicament container. The second elastomeric member, a second portion of the medicament container and the stopper collectively define a vent volume. A first retainer of the stopper is configured to engage a first portion of a carrier to limit movement of the medicament container when in a first position. A second retainer of the stopper is configured to engage a second portion of the carrier to limit movement of the medicament container when in a second position.
