Abstract: A drug delivery device and method of using the same may include a housing having an opening and a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening. The drug storage container may be coupled with the housing such as to substantially prevent relative movement therebetween. A guard may be positioned adjacent to the opening and operably coupled with the plunger biasing member such that a relative movement between the guard and the housing permits release of a plunger biasing member to urge a plunger in to expel a drug from the drug storage container. A lock component may be configured to resist the relative movement between the guard and the housing until the lock component is released by a user force, whereafter the user force drives the housing and the drug storage container toward an injection site.

Abstract: A drug delivery device including a housing, a drug storage container, and a removable cap is provided. The removable cap may be configured to be removably coupled with the housing such that the removable cap has a storage position where the removable cap is coupled with the housing and at least partially covering an opening in the housing and a removed position where the removable cap is not coupled with the housing. The removable cap may include an outer portion, an inner portion, and a gap separating at least a portion of the inner portion and at least a portion of the outer portion such that the at least a portion of the outer portion is allowed to bend with respect to the at least a portion of the inner portion if the at least a portion of the outer portion is subjected to an external force. Additionally or alternatively, the removable cap may be configured such that an external force applied to the removable cap induces at least one bending moment in a proximal end and/or a distal end of the removable cap.
