Abstract
A tamper evident, removable and anti-rotative lock for a rotatable plunger with a manually operable dispensing pump in which the plunger has a hollow stem reciprocable through an annular collar of the pump during pumping operation, the lock comprising an arcuate strip partially surrounding the stem and located between the stem and the collar when the lock is installed on the pump, the strip having at least one tooth, protuberance or rib adapted to engage the collar when the lock is installed for preventing rotation between the strip and the collar, and axially extending mating rib and groove elements on the strip and on the stem when the lock is installed on the pump for transmitting the rotative immobility to the plunger from the strip.
