ABSTRACT:
A constant diameter passageway within a dispensing tip channels and dispenses a cyanoacrylate adhesive from a container through a discharge outlet at the extremity of the tip. A cap for the tip includes a plunger for matingly and penetrably engaging the passageway to force reverse flow of the cyanoacrylate adhesive back into the container. The forced flow, due to the viscosity and surface tension characteristics of the cyanoacrylate adhesive, initiates complete drainage of the passageway and prevents any crusting of the cyanoacrylate within the passageway and clogging of the passageway.
