An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening; a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle; a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle; a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane to restrain movement thereof, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle.

1. An evacuated bottle system, comprising: a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening;a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle;a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle;a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle;the second portion of the funnel includes a floor that extends radially outward relative to the first portion of the funnel and a second wall extending axially outward from the floor;the bore includes a first bore and a second bore, each having a respective lateral dimension;the first portion defines the first bore and the second portion defines the second bore, wherein the second bore has a greater lateral dimension than the first bore;the self-sealing membrane is provided on a serum stopper, wherein the serum stopper includes a first portion extending axially inward to the interior of the bottle and being insertably received in the first bore of the funnel; andthe serum stopper includes a second portion extending radially outward relative to the first portion and residing in the second bore of the funnel. 2. The system of claim 1, wherein the cover portion includes an annular ring defining a central opening, the annular ring defining plural evacuating openings spaced radially outward from the central opening. 3. The system of claim 1, wherein the cover portion defines at least one evacuating opening, the at least one evacuating opening being located over at least a portion of a perimeter of the self-sealing membrane. 4. The system of claim 1, wherein the cover portion defines three evacuating openings located over at least a portion of a perimeter of the self-sealing membrane, the three evacuating openings are circumferentially spaced from each other and located on a common circle. 5. The system of claim 4, wherein the common circle is aligned with a joint between the perimeter of the self-sealing membrane and the funnel. 6. The system of claim 1, wherein the first portion of the serum stopper has a circular end. 7. The system of claim 1, wherein the first portion of the serum stopper includes a pair of legs spaced from each other by a gap. 8. The system of claim 1, wherein the cap includes a wall extending axially inward relative to the cover portion and overlying a portion of the neck, wherein the wall and the neck are attached to each other by cooperating threads formed thereon. 9. The system of claim 1, wherein the bottle is constructed of a shatter resistant material. 10. The system of claim 9, wherein the shatter resistant material is plastic or a medical grade plastic. 11. The system of claim 1 further comprising a chamber adapted to receive the bottle with cap assembly attached thereto, the chamber including a vacuum source adapted to apply a lower pressure than a pressure within the hollow interior to cause at least a portion of the self-sealing membrane to move axially outward within the gap and draw fluid from the hollow interior to form a vacuum or lower pressure within the bottle. 12. The system of claim 1 further comprising a pressure device placed in fluid communication with the cap assembly and adapted to apply suction to the cap assembly to displace at least a portion of the self-sealing membrane axially upward into the gap to create fluid communication between an implement and the hollow interior of the bottle until a selected lower pressure is attained within the bottle. 13. The system of claim 12 wherein the cap defines evacuation openings therein, wherein the implement fluidly communicates with the evacuation openings. 14. The system of claim 12, wherein the pressure device includes a housing defining a port adapted to fit over a portion of the cap assembly. 15. The system of claim 14, wherein the housing includes a seal extending into the port and adapted to seal the cap assembly within the port. 16. A bottle system, comprising: a bottle having an interior that houses a fluid, the bottle includes a neck with a rim defining an opening to the interior;a cap assembly supported by the bottle, the cap assembly includes a funnel, a self-sealing membrane, and a cap;the funnel having a first portion and a second portion, the first portion being insertable within a portion of the neck and the second portion engaging a portion of the rim to support the funnel;the funnel defines a bore that fluidly communicates with the interior of the bottle;the self-sealing membrane that covers the bore formed by the funnel to selectively seal the interior of the bottle;the cap attachable to an exterior of the neck of the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle;the second portion of the funnel includes a floor that extends radially outward relative to the first portion of the funnel and a second wall extending axially outward from the floor;the bore includes a first portion and a second portion, wherein the second portion has a greater lateral dimension than the first portion;the self-sealing membrane includes a first portion extending axially inward to the interior of the bottle and being insertably received in the first portion of the funnel; andthe self-sealing membrane includes a second portion extending radially outward relative to the first portion and residing in the second portion of the funnel. 17. The bottle system of claim 16, wherein the first portion of the self-sealing membrane includes a pair of legs. 18. The bottle system of claim 17, wherein at least one of the pair of legs includes at least one outward projection.
