Abstract: An injection device (110) comprises a housing (112) having a syringe (114) with a discharge nozzle (118). The syringe is movable between a retracted position in which the discharge nozzle is contained within the housing and an extended position in which the discharge nozzle extends from the housing. There is syringe cap (180) for enclosing the discharge nozzle. The syringe cap is removable from the syringe by rotation to the syringes. A syringe carrier (150) in the housing is adapted to restrain rotation of the syringe relative to the housing as the cap is removed.

Abstract: An injection device 110 is described having a housing 112 and a housing closure means 130. The injection device 110 houses a syringe 114 having a needle 118 which is sealed by a boot 117. The housing closure means 130 is arranged so that the boot 117 can be connected to the housing closure means 130 simply, but cannot be removed from the housing closure means 130. The housing 112 and housing closure means 130 are arranged so that upon rotation of the housing closure means 130, the housing closure means 130 member first rotates relative to the housing and then moves away from the housing. The injection device is simple to use and manufacture.
