1. A cap assembly, the cap assembly comprising: a funnel having a first portion and a second portion;the first portion including a first wall defining a first bore and the second portion including a floor extending radially outward from the first portion to form a shoulder adjacent to the first portion;a second wall extending upward from the floor defining a second bore, the first bore and second bore being in fluid communication with each other;a self-sealing membrane having a first portion and a second portion, wherein the first portion is received in the first bore and wherein the second portion is received in the second bore of the funnel and includes a perimeter that extends radially outward of the first portion to overlap at least a portion of the floor; anda cap that is configured to fit over the second portion of the funnel, the cap defining at least one evacuating opening configured to receive a suction, the cap including a cover portion that extends radially inward over at least a portion of the self-sealing membrane to retain the self-sealing membrane when the suction is applied to the evacuating opening, the cover portion defining a gap above the self-sealing membrane to allow the self-sealing membrane to be selectively displaced axially outward from the first bore of the funnel to provide fluid communication between the first bore of the funnel and the second bore of the funnel. 2. The cap assembly of claim 1, the cover portion includes an annular wall that defines a central opening, wherein the at least one evacuating opening is located radially outward of the central opening. 3. The cap assembly of claim 1, the cover portion defines three evacuating openings circumferentially spaced from each other and located on a common circle, wherein the common circle overlies the perimeter of the self-sealing membrane. 4. The cap assembly of claim 3, wherein the perimeter of the self-sealing membrane contacts the second wall of the funnel. 5. The cap assembly of claim 1, the cap further comprises a cap wall, an end of the cap wall extending axially inward of the second portion of the funnel, the cap wall defining an internal thread on an interior surface thereof. 6. A cap assembly configured to removeably attach to a bottle, comprising: a cap assembly including a funnel having a first portion and a second portion, the first portion configured to be insertable within the interior of a bottle and the second portion configured to engage a portion of the bottle to support the funnel above a rim of the bottle, 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 interior of the bottle;a 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 displacement 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. 7. The cap assembly of claim 6, 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. 8. The cap assembly of claim 6, 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. 9. The cap assembly of claim 6, 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. 10. The cap assembly of claim 9, wherein the common circle is aligned with a joint between the perimeter of the self-sealing membrane and the funnel. 11. The cap assembly of claim 6, further comprising a tapered transition between the second portion of the serum stopper and the first portion of the serum stopper. 12. The cap assembly of claim 6, wherein the first portion of the serum stopper includes a pair of legs spaced from each other by a gap. 13. The cap assembly of claim 6, 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. 14. The cap assembly of claim 6, further comprising a bottle to which the cap assembly can removeably attach, wherein the bottle is constructed of a shatter resistant material. 15. The system of claim 14, wherein the shatter resistant material is plastic or a medical grade plastic. 16. A cap assembly, comprising: a funnel configured to be positioned in a neck of a bottle, the funnel having a first portion and a second portion, where the second portion extends radially outward from the first portion to form a floor on an interior thereof and a shoulder on an exterior thereof, the first portion defining a first bore and the second portion defining a second bore fluidly connected to the first bore;a serum stopper configured to be positioned within the funnel, the serum stopper having a first portion and a second portion, the first portion of the serum stopper sized to fit within the first bore of the funnel, and the second portion of the serum stopper having the self-sealing membrane, the second portion of the serum stopper sitting on top of the floor and within an interior of the second bore of the funnel when the first portion of the serum stopper is inserted within the first bore of the funnel; anda cap having a cap wall sized to receive the funnel and the serum stopper positioned within the funnel, wherein the cap includes a cover portion extending radially inward from the cap wall, the cover portion defining the evacuating opening, the cover portion defining a gap above the serum stopper to allow the serum stopper to be displaced axially outward from the first bore of the funnel when a suction is applied to the evacuating opening. 17. The cap assembly of claim 16, further comprising a bottle having an opening on a neck, wherein the cap assembly removeably attaches to a threading on the neck of the bottle. 18. The cap assembly of claim 16, wherein the first portion of the serum stopper includes a pair of legs. 19. The cap assembly of claim 18, wherein at least one of the pair of legs includes at least one outward projection. 20. The cap assembly of claim 19, wherein the at least one outward projection engages an interior of the first bore.
