Abstract A swab is packaged in a tube having an open end and containing a culture-sustaining or bacteria identification liquid at the bottom of a tube, and a plug including a one-way isolating valve located above the liquid and a barrier member forming a leak-proof chamber between the plug and the barrier member. After removal of the swab from the tube and swabbing of a body canal or the like with the absorbent tip of the swab, the swab may be placed back in the tube with the absorbent tip adjacent the plug and within the substantially air-tight chamber. The plug may then be forced downwardly through the liquid by pressing on the end of the swab or another rigid member telescoped within the tube so as to force the liquid up through the valve into contact with the absorbent tip. A closure or cap which may be used to press on the end of the stick or the rigid member then forms a seal at the open end of the tube.
Apparatus for collecting cultures, said apparatus comprising: (a) a hollow tubular container having a closed end, an open end and sides extending therebetween; (b) a culture-sustaining medium position within said tubular container adjacent said closed ends; (c) a swab including an elongated member and an absorbent tip, said swab extending into said container; and (d) a movable piston means extending the cross tubular member and adapt to form a seal with said sides, said piston means being movable through said culture-sustaining medium toward said closed end when said swab is in pushing contact with said piston means, said piston means including valve means for allowing said culture-sustaining medium to flow through said valve means from a position adjacent said closed end through and into contact with said absorbent tip.
