Abstract

A plastic body including a generally cylindrical upper portion having an open end configured for engagement with an automated pipettor. The plastic body further includes a plurality of longitudinally oriented ribs disposed on an inner surface of the open end of the upper portion and a plurality of concave recesses disposed on an outer surface of the upper portion. Each of the recesses is disposed directly opposite an associated one of the ribs, and each of the recesses extends along at least part of the length of the associated rib.

First claim

What is claimed is:

1. A plastic body comprising:
a generally cylindrical upper portion having an open end configured for engagement with an automated pipettor;
a plurality of longitudinally oriented ribs disposed on an inner surface of the open end of the upper portion; and
a plurality of concave recesses disposed on an outer surface of the upper portion, each of the recesses being disposed directly opposite an associated one of the ribs, and each of the recesses extending along at least part of the length of the associated one of the ribs,
wherein the recesses are configured to flex or expand radially outwardly relative to an axial center of the upper portion when a force is applied to the ribs.

2. The plastic body of claim 1 , wherein the ribs are spaced equidistantly apart.

3. The plastic body of claim 1 , wherein at least one of the ribs comprises an enlarged portion proximate a distal end thereof.

4. The plastic body of claim 3 , wherein the enlarged portion comprises a detent for engaging the automated pipettor in an interference fit.

5. The plastic body of claim 1 , wherein each of the ribs comprises an enlarged portion proximate a distal end thereof.

6. The plastic body of claim 5 , wherein the enlarged portion comprises a detent for engaging the automated pipettor in an interference fit.

7. The plastic body of claim 1 , wherein a proximal end of each of the ribs is beveled.

8. The plastic body of claim 1 , wherein each of the recesses extends along the entire length of the associated one of the ribs.

9. The plastic body of claim 1 , wherein the open end of the upper portion is configured for frictional engagement with the automated pipettor.

10. The plastic body of claim 1 , further comprising a tapered lower portion.

11. The plastic body of claim 10 , wherein the tapered lower portion is closed-ended.

12. The plastic body of claim 1 , wherein the plastic body is a unitary structure.

13. The plastic body of claim 1 , wherein at least one of the ribs comprises a detent configured for engaging the automated pipettor in an interference fit.

14. The plastic body of claim 13 , wherein each of the ribs comprises a detent configured for engaging the automated pipettor.

15. The plastic body of claim 13 , wherein a proximal end of each of the ribs is beveled.

16. The plastic body of claim 13 , wherein each of the recesses extends along the entire length of the associated one of the ribs.

17. The plastic body of claim 13 , further comprising a tapered lower portion.

18. The plastic body of claim 17 , wherein the tapered lower portion is closed-ended.

19. The plastic body of claim 13 , wherein the plastic body is a unitary structure.
