Injection Device

Abstract:

An injection device comprising a housing and a cap at a distal end of the housing, the cap comprising: an outer member; an intermediate member disposed within the outer member, at least one of the intermediate member or outer member being rotatable relative to the other of the intermediate member or outer member; and, an inner member disposed within the intermediate member, and coupled to at least one of the outer member and the intermediate member, the inner member being configured to engage a needle shield in the housing. The injection device further comprises a lifting mechanism to reduce a force required to remove the cap from the housing, the lifting mechanism comprising at least one axially-inclined portion in engagement with at least one lifting portion such that rotational movement of the outer member or intermediate member is converted into an axial movement of the inner member from the housing.
