ABSTRACT:
A two-piece telescoping cylinder made of a flexible plastic material forms a disposable container for a swab and a liquid culture medium. The upper piece serves as a handle for the swab and cooperates with the lower piece to form a sealed container for the swab and liquid. A generally conical plug having a base slightly larger than the inside diameter of the cylinder divides the lower piece into two compartments, sealing the liquid from the swab. When the telescoping parts are pushed together, the swab contacts the plug and pivots it in relation to the side walls of the tube so that the seal is broken and the liquid may saturate the swab or a cotton wad immediately above the swab.
