1. An adapter cap for a sample collection container, comprising: a monolithic elongate body having an upper neck portion with an open needle bore, wherein the upper neck portion merges into a larger lower body portion with an open internal cavity configured to receive a sample collection container,
1. An adapter cap for a sample collection container, comprising: a monolithic elongate body having an upper neck portion with an open needle bore, wherein the upper neck portion merges into a larger lower body portion with an open internal cavity configured to receive a sample collection container, wherein the needle bore has a downwardly extending wall with an inner surface that comprises (i) a plurality of circumferentially spaced apart longitudinally extending flat surfaces and (ii) first and second circumferentially spaced apart threads that extend radially inward from the inner surface so that respective innermost edges reside on opposing sides of an axially extending centerline of the elongate body, and wherein at least some of the plurality of circumferentially spaced apart longitudinally extending flat surfaces are separated by neighboring wall segments having a different wall thickness than the wall segments comprising the flat surfaces. 2. The adapter cap of claim 1, wherein the upper neck portion has a circular outer perimeter and merges into the larger lower body portion, and wherein the upper neck portion is concentrically aligned with the open internal cavity. 3. The adapter cap of claim 1, wherein the flat surfaces extend a distance above and below the threads. 4. The adapter cap of claim 3, wherein the threads have a respective injection molded thread configuration and the thread on one side of the needle bore resides above the thread on an opposing side of the needle bore, and wherein the first and second threads circumferentially extend only about a sub-portion of a circumference of the inner wall. 5. The adapter cap of claim 1, wherein the plurality of flat surfaces is between 2-6 flat surfaces, wherein the plurality of flat surfaces project outward a distance from the inner surface of the downwardly extending wall so that the wall segments with the flat surfaces have a greater wall thickness than the neighboring wall segments, and wherein the downwardly extending wall of the upper neck portion of the needle bore is cylindrical. 6. The adapter cap of claim 1, wherein the elongate body comprises a molded polymeric material with a substantially constant wall thickness of between about 0.5 mm to about 2 mm. 7. The adapter cap of claim 6, wherein the wall thickness of the elongate body is about 1 mm, and wherein the polymeric material is polypropylene. 8. The adapter cap of claim 1, wherein the wall segments with the flat surfaces define wall segments with increased wall thickness of between 0.01 mm and 0.03 mm, average, relative to the neighboring wall segments. 9. The adapter cap of claim 1, wherein the plurality of longitudinally extending flat surfaces are four flat surfaces that are symmetrically circumferentially spaced apart. 10. The adapter cap of claim 1, wherein the plurality of longitudinally extending flat surfaces have a common substantially constant width that is between about 5%-30% of a major diameter of the needle bore. 11. The adapter cap of claim 1, wherein the needle bore has a major diameter of about 4.60 mm, and wherein the plurality of longitudinally extending flat surfaces have a width that is between about 0.25 mm to about 1 mm. 12. The adapter cap of claim 1, wherein at least some of the flat surfaces have a length of between about 2-2.8 mm. 13. The adapter cap of claim 1, wherein the needle bore has a major diameter of about 4.60 mm, and wherein opposing pairs of the plurality of longitudinally extending flat surfaces have a thickness sufficient to define a nominal diameter therebetween of about 4.40 mm. 14. The adapter cap of Claim 1 in combination with a culture collection container with an upper portion thereof residing in the open internal cavity of the larger lower body portion under the needle bore. 15. An adapter cap for a sample collection container, comprising: a monolithic elongate body having an upper neck portion with an internal bore, wherein the upper neck portion merges into a larger lower body portion with an open internal cavity configured to receive a sample collection container, wherein the upper neck portion has a downwardly extending cylindrical outer wall with an inner surface providing the internal bore, wherein the inner surface comprises (i) a plurality of circumferentially spaced apart longitudinally extending flat surfaces that are separated by neighboring wall segments of lesser wall thickness and (ii) first and second circumferentially spaced apart threads that extend radially inward from the inner surface and extend only partially about a circumference of the internal needle bore, and wherein respective innermost edges of the threads reside on opposing sides of an axially extending centerline of the elongate body. 16. The adapter cap of claim 15, wherein the plurality of longitudinally extending flat surfaces have a common substantially constant width that is between about 5%-30% of a major diameter of the internal bore. 17. The adapter cap of claim 15, wherein the internal bore has a major diameter of about 4.60 mm, and wherein the plurality of longitudinally extending flat surfaces have a width that is between about 0.25 mm to about 1 mm. 18. The adapter cap of claim 15, wherein at least some of the flat surfaces have a length of between about 2-2.8 mm. 19. A method of fabricating an adaptor cap, comprising: providing an injection mold cavity;placing a core pin in the mold cavity, wherein the core pin has an end portion with a plurality of longitudinally extending spaced apart flat surfaces and a thread configuration;introducing a moldable polymer material into the injection mold cavity having the core pin;injection molding a monolithic adapter cap of claim 1; andusing a straight pull to remove the core pin thereby exposing the injection molded adapter cap with the needle bore without requiring spinning to form the threads to fabricate the adaptor cap. 20. The method of claim 19, further comprising placing a cavity pin in the mold cavity aligned with the core pin before the injection molding, wherein the cavity pin has a plurality of longitudinally extending spaced apart flat surfaces and a thread configuration. 21. The method of claim 19, wherein the injection molding is carried out to form the needle bore having the plurality of longitudinally extending flat surfaces so that the plurality of longitudinally extending flat surfaces extend above and below the threads.
