ABSTRACT:
A device for collecting samples of blood and other fluids for clinical testing purposes. The device includes an open-ended vial and a cap equipped with a capillary tube for drawing samples into the wall. The cap is internally threaded and the vial is provided at its open end with at least one arcuate flange engagable with the threads of the cap to shift the parts axially as they are rotated with respect to each other. A vent opening in the cap is sealed by the flange when the parts are threaded tightly together and is unsealed to allow passage of air to and from the vial when the parts are unthreaded but still connected. Retention lips provided by the cap retain the parts together when they are in their unthreaded condition.
