The trigger button (6) has a concave position and a convex position. Movement of the trigger button (6) from the convex position to the concave position causes activation of the drive mechanism (5). ## Claims ### Claim 1 A medicament delivery device comprising: a container of a medicament, the container including a needle; a case adapted to hold the container, wherein the container is slidably disposed in the case and moves between a first position in which the needle is substantially covered by the case and a second position in which the needle extends beyond a distal end of the case; a drive mechanism adapted to expel the medicament from the container; a trigger button disposed on the case and operably coupled to the drive mechanism, the trigger button having a concave position and a convex position, wherein movement of the trigger button between the convex position and the concave position causes activation of the drive mechanism; and an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button. ### Claim 2 (depends on 1) The medicament delivery device according to claim 1, wherein the drive mechanism includes a plunger adapted to apply a force on a stopper in the container and a drive spring adapted to apply a force on the plunger. ### Claim 3 (depends on 1) The medicament delivery device according to claim 1, wherein a diameter of the trigger button is substantially equal to a diameter of the case. ### Claim 4 (depends on 1) The medicament delivery device according to claim 1, wherein translation of the interlock member from the extended position to the retracted position causes transition of the trigger button from the concave position to the convex position. ### Claim 5 (depends on 1) The medicament delivery device according to claim 1, wherein the interlock member is biased in the extended position. ### Claim 6 (depends on 1) The medicament delivery device according to claim 1, wherein the interlock member is locked in the extended position after the interlock member translates from the retracted position to the extended position and the trigger button transitions from the convex position to the concave position. ### Claim 7 (depends on 1) The medicament delivery device according to claim 1, wherein an audible feedback is generated when the trigger button transitions from the concave position to the convex position. ### Claim 8 (depends on 1) The medicament delivery device according to claim 1, wherein the trigger button is biased in the concave position. ### Claim 9 (depends on 1) The medicament delivery device according to claim 1, wherein the trigger button is disposed on a proximal end of the case. ### Claim 10 (depends on 9) The medicament delivery device of claim 9, wherein the trigger button is disposed on a proximal-most end of the case. ### Claim 11 (depends on 1) The medicament delivery device according to claim 1, wherein the trigger button is made from at least one flexible thermoelastic polymer. ### Claim 12 (depends on 11) The medicament delivery device according to claim 11, wherein the at least one flexible thermoelastic polymer includes a styrenic block copolymer, a polyolefin blend, an elastomeric alloy, thermoplastic polyurethane, thermoplastic copolyester or a thermoplastic polyamide. ### Claim 13 (depends on 11) The medicament delivery device according to claim 11, wherein the trigger button creates a hermetic seal for a proximal end of the case. ### Claim 14 A medicament delivery device comprising: a case adapted to hold a container of a medicament; a trigger button disposed on the case, the trigger button having a convex position and a concave position, the trigger button configured to move between the convex position and the concave position; a drive mechanism operably coupled to the trigger button, the drive mechanism configured to expel the medicament from the container in response to the trigger button moving between the convex position and the concave position; and an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button. ### Claim 15 (depends on 14) The medicament delivery device according to claim 14, wherein the trigger button is biased in the concave position. ### Claim 16 (depends on 14) The medicament delivery device according to claim 14, wherein the trigger button has elastic properties that produce an audible feedback in response to the trigger button moving between the convex position and the concave position. ### Claim 17 (depends on 14) The medicament delivery device of claim 14, wherein the trigger button is disposed on a proximal-most end of the case. ### Claim 18 A medicament delivery device comprising: a case adapted to hold a container of a medicament; a drive mechanism adapted to expel the medicament from the container, wherein the drive mechanism includes a plunger adapted to apply a force on a stopper in the container and a drive spring adapted to apply a force on the plunger; a trigger button disposed on the case and operably coupled to the drive mechanism, the trigger button having a concave position and a convex position, wherein movement of the trigger button between the convex position and the concave position causes activation of the drive mechanism; and an interlock member telescopically coupled to the case and translatable between an extended position relative to the case and a retracted position relative to the case, wherein the interlock member is operably coupled to the trigger button.
