Abstract

A specimen collection container includes inner and outer tubes. The inner tube includes a bottom end, a top end, and a sidewall extending therebetween defining an interior. The sidewall includes an inner surface and an outer surface having at least one annular protrusion extending therefrom. The inner tube includes at least one funnel portion adjacent the top end for directing a specimen into the inner tube interior, and an annular ring disposed about a portion of the outer surface of the sidewall adjacent the top end. The outer tube includes a bottom end, a top end, and a sidewall extending therebetween, the sidewall having an outer surface and an inner surface defining an annular recess adapted to receive a portion of the annular protrusion therein. The inner tube is disposed within the outer tube and a portion of the top end of the outer tube abuts the annular ring.

First claim

What is claimed is:

1. A specimen collection container comprising:
an inner tube having a closed bottom end, a top end, and a sidewall extending therebetween defining an inner tube interior, said sidewall having an inner surface including at least one angled surface extending toward the closed bottom end, the inner tube comprising at least one funnel portion adjacent the top end, said funnel portion including at least one introducing surface having a curvature configured for directing a specimen down the funnel and into the inner tube interior, said angled surface and said at least one introducing surface together forming a combined angled surface; and
an outer tube comprising a bottom end, a top end including an upper end, and a sidewall extending therebetween, wherein the inner tube is disposed at least partially within the outer tube such that the at least one funnel portion sits above the upper end of the outer tube, wherein the sidewall of the inner tube is configured to cooperate with the sidewall of the outer tube to secure the inner tube within the outer tube, wherein the sidewall of the inner tube has an outer surface having at least one annular protrusion extending therefrom and the sidewall of the outer tube has an inner surface defining an annular recess adapted to receive at least a portion of the annular protrusion therein to secure the inner tube within the outer tube.

2. The specimen collection container of claim 1 , wherein the sidewall of the inner tube includes an annular ring extending outwardly therefrom and the at least one funnel portion is located adjacent to and above the annular ring and wherein a portion of the upper end of the outer tube abuts the annular ring.

3. The specimen collection container of claim 1 , wherein the top end of the inner tube comprises a second funnel portion, such that the second funnel portion is substantially opposite the at least one funnel portion.

4. The specimen collection container of claim 1 , wherein at least one of the sidewall of the inner tube and the sidewall of the outer tube includes at least one fill-line for allowing a clinician to determine the volume of specimen within the inner tube.

5. The specimen collection container of claim 1 , wherein the bottom end of the outer tube comprises at least one vent for venting air from the space defined between the inner tube and the outer tube.

6. The specimen collection container of claim 1 , wherein the inner tube comprises at least one stabilizer extending therefrom and extending along the sidewall of the inner tube in a longitudinal direction for contacting a portion of an inner surface of the sidewall of the outer tube.

7. The specimen collection container of claim 1 , wherein the inner tube completely seals the top end of the outer tube.

8. The specimen collection container of claim 1 , further comprising a specimen collection cap sealing at least one of the top end of the inner tube and the top end of the outer tube.

9. A specimen collection container comprising:
an inner tube having a closed bottom end, a top end, and a sidewall extending therebetween defining an inner tube interior, the inner tube comprising at least one funnel portion adjacent the top end for directing a specimen into the inner tube interior;
an outer tube comprising a bottom end, a top end including an upper end, and a sidewall extending therebetween, wherein the inner tube is disposed at least partially within the outer tube such that the at least one funnel portion sits above the upper end of the outer tube; and
a specimen collection cap sealing at least one of the top end of the inner tube and the top end of the outer tube,
wherein the specimen collection cap includes a top surface, an annular shoulder depending therefrom, and an annular interior wall depending from the top surface with the annular shoulder circumferentially disposed about the annular interior wall.

10. The specimen collection container of claim 9 , wherein a tube receiving portion is defined between the annular shoulder and the annular interior wall, and wherein at least a portion of the at least one funnel portion is received within the tube receiving portion.

11. The specimen collection container of claim 9 , wherein the specimen collection cap includes a self-sealing elastomeric stopper.

12. The specimen collection container of claim 11 , wherein the elastomeric stopper comprises a concave receiving surface adjacent a top surface of the specimen collection cap for directing an instrument to an apex of the concave receiving surface.

13. The specimen collection container of claim 11 , wherein the elastomeric stopper comprises an inverted receiving surface adjacent a bottom end of the specimen collection cap.

14. The specimen collection container of claim 9 , further comprising a plurality of ribs extending along a portion of an exterior surface of the specimen collection cap.

15. The specimen collection container of claim 9 , wherein the specimen collection cap includes a top surface and an annular shoulder depending therefrom having an inner surface, wherein at least a portion of the inner surface of the annular shoulder and an outer surface of the inner tube interact to form a seal, wherein the seal comprises a tortuous fluid path.

16. The specimen collection container of claim 9 , wherein the inner tube and the outer tube are formed from two different polymeric materials.

17. The specimen collection container of claim 1 , wherein an overall length of the container is a length that is compatible with standard industry specifications for automated clinical processes.

18. The specimen collection container of claim 17 , wherein the overall length of the container is between 75 mm and 100 mm.
