ABSTRACT:
A liquid dispenser has relatively rotatable closure, sleeve and plunger members, the latter two being locked against reciprocation of the plunger member by a misalignment between ribs and grooves therebetween. One of the grooves has a pair of upstanding pegs on opposite sides so as to not only avoid inadvertent alignment when the ribs and grooves are in a misaligned position, but to also permit the plunger and sleeve members to rotate together as the rib abuts against one or the other of the pegs when in a misaligned position. A spacer element surrounding the plunger rod maintains the inlet valve in a closed position despite a slight separation between the plunger and sleeve members when rotated to the misaligned position. Also, the closure member is adapted to be removed only with difficulty from the container on which it is affixed.
