Abstract

The dispenser has a syringe housing with a narrow open end section for dispensing the viscous material through a hollow needle and a wider end opposite this. There is a supply of viscous material inside the housing and a cast stopper above the viscous material in the direction of the wider end of the syringe housing. The stopper is of a waxy, slippery, easily melted substance, such as hard paraffin wax, which may be blended with resin and synthetic wax to give a mixt. melting at 93.2 degrees C. A simple, easily produced, accurate and reliable device eliminating all the problems of known dispensers, esp. that of excluding air.
