ABSTRACT:
A self-contained swab includes a hollow stick, one or both ends of which is formed with a fluid storing chamber separated from the stick by a transverse wall and the fluids stored within sealed by a thin membrane. The stick is further formed with two annular rings in the vicinity of the fluid storing chamber. A socket means includes a clamping end by means of which the socket means is couplable with the stick and slidable between the two annular rings. The other end of the socket means, on which a nonwoven cottom mass is carried, is formed with an inwardly projecting prong. The prong impales the thin membrane releasing the fluid when the socket means is slid back along the stick from the second to the first annular ring. The fluid absorbed by the cotton mass can then be appropriately applied.
