Abstract
The present invention is a collection assembly useful for collecting small quantities of blood. The assembly comprises a container with an integral lip for facilitating collection of the blood and a cap suitable for enclosing the container. The assembly further comprises a sealing arrangement for securing the cap to the container using a protrusion on the cap and a locking ring on the container, wherein the container includes a riser below the locking ring that interacts with the protrusion on the cap to unsecure the cap from the container, when the cap is rotated on the container.
