<p>DISPENSER A dispenser for semi-solid material such as deodorant comprises a tubular barrel, a radial flange of which holds captive a knurled drive wheel for rotation about the axis of the barrel. An elevator is mounted on a spindle connected to the drive wheel and is adapted to move deodorant up and down the barrel on rotation of the wheel. To facilitate bottom-filling of the dispenser the elevator is formed from a radially inner part and a radially outer part. The radially outer part is positioned in the barrel before filling, and the radially inner part, preassembled on the spindle, is then clipped into the radially outer part whilst the deodorant is still in liquid form.</p> |
