Abstract
A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.
