1. A method of removing a syringe from a packaging, the method comprising:
peeling off a removable cover from a blister packaging tray of the packaging, the blister packaging tray having a cavity configured to contain the syringe therein, wherein the blister packaging tray includes a dome-shaped projection associated with and extending away from a base of the cavity of the blister packaging tray in a direction opposite to an opening of the cavity, and the dome-shaped projection is aligned with the syringe;
pushing a portion of the dome-shaped projection towards the cavity of the blister packaging tray, wherein pushing the portion of the dome-shaped projection causes a portion of the blister packaging tray to flex; and
orienting the blister packaging tray so that the opening of the cavity faces a sterile surface to release the syringe from the blister packaging tray.
 
7. A method of removing a syringe from a packaging, the packaging including a tray having a cavity, a dome-shaped projection associated with the cavity, and an opening covered by a gas-permeable material, wherein the dome-shaped projection extends away from a base of the cavity in a direction opposite to the opening of the tray;
the method comprising:
removing the gas-permeable material so as to expose the opening of the tray;
pushing the dome-shaped projection towards the cavity and a barrel of the syringe, wherein the step of pushing the dome-shaped projection also causes a portion of the tray to flex; and
ejecting the syringe from the tray.
 
18. A method of removing a syringe from a packaging that includes a flexible tray having a base for receiving the syringe and a dome-shaped projection extending away from the base in a direction opposite to the syringe;
the method comprising:
removing a cover that is coupled to the flexible tray and disposed over the base to expose an opening of the flexible tray, wherein the cover is permeable to a gaseous sterilant;
pushing the dome-shaped projection towards the syringe to flex a portion of the base, wherein the dome-shaped projection is hollow and open towards the opening of the flexible tray; and
ejecting the syringe from the base.
