Abstract
A manually operated rotary syringe comprises a fixed base member and a relatively rotable cap member, one of which has an arcuate recess and the other of which carries a mating plug which is received in the arcuate recess in fluid tight relationship with the walls of the recess. Outlet means extend through the stationary base from one end of the arcuate recess such that on rotation of the cap the plug will be caused to traverse the recess towards the outlet to expel the contents of the recess through the outlet means in the base. Means are provided to permit rotation of the cap with respect to the base in only in the direction of operation.
