Abstract: A drug delivery system includes a container comprising a luer compartment and a fluid compartment, a luer fitting arranged within the luer compartment and in fluidic communication with the fluid compartment, and a dispenser in fluidic communication with the fluid compartment. A method of aseptically transferring a drug to such a drug delivery system may include providing a vial comprising the drug to be transferred, withdrawing a volume of the drug from the vial with a syringe, coupling the syringe to a drug delivery system via the luer fitting, transferring the drug from the syringe to the drug delivery system, and decoupling the syringe from the drug delivery system.

Abstract: Various nesting structures for storage, transport and/or assembly of dispensers and containers are described herein. For example, a packaging structure for a plurality of drug dispensers may include a support surface and a plurality of dispenser covers arranged on the support surface, where at least one dispenser cover includes a locking flexure member configured to couple a dispenser to the at least one dispenser cover.
