Abstract: An autoinjector device includes a dose cassette having an outer container and a needle cap having a base with a diameter larger than the outer container of the dose cassette. The autoinjector device further include a housing for receiving the dose cassette, a clasp mechanism configured to hold the dose cassette within the housing, and an actuator configured to move the dose cassette proximally within the housing after the dose cassette is secured within the housing. The movement of the dose cassette causes the base of the needle cap to mechanically engage with a distal end of the housing, and the mechanical engagement between the base of the needle cap and the distal end of the housing causes the needle cap to separate from the dose cassette.
