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 directing 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 gradually 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 inner tube and the outer tube are press-fit together within the same forming process or are in-molded, wherein the inner tube and outer tube are molded and assembled in the same press,
wherein a portion of the sidewall of the inner tube including at least a portion of the angled surface comprises an exterior stabilizer extending along the sidewall of the inner tube in a longitudinal direction, the exterior stabilizer being configured to contact a portion of an inner surface of the sidewall of the outer tube, the angled surface of the inner tube being angled relative to the exterior stabilizing surface and wherein the sidewall of the inner tube is tapered from the at least one angled surface to the closed bottom end to increase a column height of the specimen disposed within the interior of the inner tube.

2. The specimen collection container of claim 1 , 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.

3. 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.

4. 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.

5. 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.

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

7. 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.

8. 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.

9. The specimen collection container of claim 8 , wherein the overall length of the container is between 75 mm and 100 mm.

10. The specimen collection container of claim 1 , wherein an outer surface of the exterior stabilizer includes an inwardly tapered portion extending away from and out of contact with the inner surface of the sidewall of the outer tube.

11. The specimen collection container of claim 1 , wherein the at least one angled directing surface extends toward the closed bottom end and is configured for directing an instrument toward the closed bottom end.

12. 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 directing 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 gradually 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 inner tube and the outer tube are press-fit together,
wherein a portion of the sidewall of the inner tube including at least a portion of the angled surface comprises an exterior stabilizer extending along the sidewall of the inner tube in a longitudinal direction, the exterior stabilizer being configured to contact a portion of an inner surface of the sidewall of the outer tube, the angled surface of the inner tube being angled relative to the exterior stabilizing surface and wherein the sidewall of the inner tube is tapered from the at least one angled surface to the closed bottom end to increase a column height of the specimen disposed within the interior of the inner tube, 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.

13. 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 directing 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 gradually angled surface, said top end of said inner tube having a receiving portion diameter D 1 and an annular ring having an outer diameter D 2 that is greater than D 1 , said at least one funnel portion being located adjacent to and extending above the annular ring; and
an outer tube comprising a bottom end, a top end, and a sidewall extending therebetween defining an outer tube interior having an inner diameter D 3 which is greater than D 1 and less than D 2 and wherein the inner tube is disposed at least partially within the outer tube, wherein the inner tube and the outer tube are press-fit together within the same forming process or are in-molded, wherein the inner tube and outer tube are molded and assembled in the same press,
wherein a portion of the sidewall of the inner tube including at least a portion of the angled surface comprises an exterior stabilizer extending along the sidewall of the inner tube in a longitudinal direction, the exterior stabilizer being configured to contact a portion of an inner surface of the sidewall of the outer tube, the angled surface of the inner tube being angled relative to the exterior stabilizing surface, and wherein the sidewall of the inner tube is tapered from the at least one angled surface to the closed bottom end to increase a column height of the specimen disposed within the interior of the inner tube.

14. The specimen collection container of claim 13
