ABSTRACT OF THE DISCLOSURE A speciman container primarily for medical use is described and comprises a tubular container body and a cap for the body. The body defines a cavity to receive a specimen and includes an annular neck which defines an opening providing axis to said cavity and which has an outer end portion including an end edge surrounding said opening. The cap is fitted to the neck of the container body and closes the opening and comprises a circular top having an inner surface formed with an annular groove arranged to closely receive the outer end portion of said neck, and an annular skirt which projects outwardly from the inner surface of the top and extends around the neck of the container body. The skirt and neck have co-operatinq screw threads for removably retaining the cap on the container body and the cap further comprises an annular seal member formed integrally with the inner surface of the circular top and arranged to fit inside the opening of the container body. The annular seal member is in the form of a relatively thin, resilient lip disposed inwardly of said groove in said top and having a flat outer surface which is co-extensive with an inner wall of said groove and which lies in continuous surface-to-surface contact with the inner surface of said neck of the container body, thereby sealing said opening in the container body. The lip is outwardly inclined toward the skirt of the cap when the cap is separate from the container body so as to be progressively deflected inwardly by contact with the neck of container body as the cap is screwed on to said body, whereby the seal member is urged against the annular neck portion of the container body under preload when the cap is in its fully tightened position.
