1. An apparatus, comprising:
a medicament container configured to be movably coupled to a carrier of a medicament delivery device, the carrier including a needle; a first elastomeric member disposed within a proximal end portion of the medicament container; a second elastomeric member disposed within the medicament container, the first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively defining, at least in part, a medicament volume; and a stopper 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 defining, at least in part, a vent volume, the stopper having a first retention portion and a second retention portion, the first retention portion configured to engage a first portion of the carrier to limit movement of the medicament container relative to the carrier when the medicament container is in a first position relative to the carrier, the second retention portion configured to engage a second portion of the carrier to limit movement of the medicament container relative to the carrier when the medicament container is in a second position relative to the carrier, the stopper configured to fluidically isolate the needle from the vent volume when the medicament container is in the first position, the needle is disposed through a portion of the stopper to fluidically couple the vent volume to the needle when the medicament container is in the second position, the needle is disposed through a portion of the second elastomeric member to fluidically couple the medicament volume to the needle when the medicament container is in a third position relative to the carrier. |
