A sterilizing apparatus and related method are provided for sterilizing an object, such as a container. The sterilizing apparatus may include a housing, a source of fluid sterilant, a fluid sterilant station for transmitting fluid sterilant onto a surface of the object, a flow system for circulating air or gas within the housing, a system for removing fluid sterilant from the surface of the object, and a system for evacuating fluid sterilant from the housing. The container may include a body defining a storage chamber for receiving a product, and a container closure. A sealing portion may be engageable with the body to form a substantially dry hermetic seal between the container closure and body.

1. A method comprising: (i) placing an object into a housing(ii) transmitting a fluid sterilant into the housing;(iii) moving or flowing the fluid sterilant in a desired flow pattern within the housing;(iv) contacting the fluid sterilant with at least a portion or surface of the object for a sufficient time to sterilize at least said at least a portion or surface, and thereby sterilizing at least said at least a portion or surface with the fluid sterilant;(v) transmitting a first application of air or another gas into the housing and onto the at least a portion or surface of the object, thereby removing fluid sterilant from the at least a portion or surface of the object;(vi) transmitting a second application of air or another gas into the housing and onto the at least a portion or surface of the object, thereby further removing fluid sterilant from the at least a portion or surface of the object; and(vi) evacuating the fluid sterilant from the housing. 2. A method as defined in claim 1, wherein the evacuating step includes drawing the fluid sterilant out of the housing with at least one vacuum source. 3. A method as defined in claim 1, wherein the evacuating step further comprises exhausting or pumping the fluid sterilant through an exhaust manifold of the housing. 4. A method as defined in claim 3, further comprising chemically processing the fluid sterilant during or after the evacuating step. 5. A method as defined in claim 1, further comprising transmitting a sterile gas into the housing during one or more of steps (iii) to (vi). 6. A method as defined in claim 1, wherein said moving or flowing step includes pumping the fluid sterilant. 7. A method as defined in claim 1, further comprising: mounting the object on a conveyor located at least partially within the housing, the housing having an inlet end and an outlet end, and the conveyor having a direction of conveyor movement between the inlet end and the outlet end of the housing;moving the object on the conveyor to at least one sterilizing station within the housing;performing the contacting step at the at least one sterilizing station;moving the object on the conveyor to a first sterilant removal station located downstream of the sterilizing station in the direction of conveyor movement;transmitting said first application of air or another gas into the housing through at least one first nozzle and onto the object at the first sterilant removal station, and thereby removing fluid sterilant from the object;moving the object on the conveyor to a second sterilant removal station located downstream of the second sterilant removing station in the direction of conveyor movement; andtransmitting said second application of air or another gas into the housing through at least one second nozzle and onto the object at the second sterilant removal station and thereby further removing fluid sterilant from the object. 8. A method as defined in claim 1, wherein the fluid sterilant comprises hydrogen peroxide. 9. A method as defined in claim 1, wherein the housing has an inlet end and an outlet end, and the moving or flowing step includes creating an over pressure of sterile gas from a source of sterile gas coupled in fluid communication with the housing and separate from the source of fluid sterilant, and directing a flow of the sterile gas within the housing substantially in a direction from the outlet end toward the inlet end of the housing. 10. A method as defined in claim 1, wherein the object is a sealed container. 11. A method as defined in claim 10, wherein the container has a needle penetrable and resealable portion defining a closure for the container, and the contacting step includes contacting fluid sterilant with an external surface of the resealable portion. 12. A method as defined in claim 1, wherein the housing defines a sterilizing zone, and further comprising preventing ambient atmosphere or contaminants from outside the housing from entering the sterilizing zone throughout steps (i) through (vi). 13. An apparatus comprising: a housing,a source of fluid sterilant placeable in fluid communication with the housing;at least one fluid sterilant station located within the housing, coupleable in fluid communication with the source of fluid sterilant, and configured to transmit fluid sterilant into the housing and into contact with at least a portion or surface of an object located within the housing for a sufficient time to sterilize said at least a portion or surface;a flow system, configured to cause fluid sterilant to move or flow in a desired flow pattern within the housing;a sterilant removal system configured to transmit a first application of air or another gas into the housing and onto the at least a portion or surface of the object and thereby remove fluid sterilant from the at least a portion or surface of the object; andtransmit a second application of air or another gas into the housing and onto the at least a portion or surface of the object and thereby further remove fluid sterilant from the at least a portion or surface of the object; anda sterilant evacuation system configured to remove the fluid sterilant from the housing. 14. An apparatus as defined in claim 13, wherein the sterilant evacuation system comprises at least one vacuum source or pump configured to draw fluid sterilant from the housing. 15. An apparatus as defined in claim 13, wherein the sterilant evacuation system comprises an exhaust manifold configured for exhausting or pumping fluid sterilant therethrough. 16. An apparatus as defined in claim 15, wherein the sterilant evacuation system comprises a catalytic converter configured to process fluid sterilant during or after said pumping or exhausting of fluid sterilant through the exhaust manifold. 17. An apparatus as defined in claim 13, further comprising a source of sterile gas placeable in fluid communication with the housing to one or more of (i) move or flow fluid sterilant in a desired flow pattern within the housing; or (ii) remove fluid sterilant from the housing. 18. An apparatus as defined in claim 13, wherein the flow system includes a pump. 19. An apparatus as defined in claim 13, wherein the housing defines an inlet end and an outlet end; wherein the apparatus further comprises a conveyor located at least partially within the housing and defining at least one position thereon configured to support and move at least one object in a direction from the inlet end toward the outlet end; wherein the at least one fluid sterilant station is located downstream of the inlet end in a direction of conveyor movement; and wherein the apparatus further comprises a first sterilant removal station located between the at least one fluid sterilant station and the outlet end of the housing and coupleable in fluid communication with air or another gas for removing fluid sterilant from the object, and a second sterilant removal station located downstream of the first sterilant removing station and coupleable in fluid communication with air or another gas for removing fluid sterilant from the object. 20.
