Abstract

The aim is to avoid the sepn of components that sometimes occurs after mixing the which is believed to be due to friction arising when the tube is subsequently bent to reach the upper teeth. A delivery tube (1) is used which maintains its cross sectional area even when it is bent. This is pref. done by making the tube with two longitudinal slits (4) which remain closed while the tube is straight (i. e. until mixing is complete) and open only afterwards, when the tube is bent. Initially the slits may be held closed by removable rings, or they may be only partly cut so that they are not fully formed until the tube bends.
